CONCRETE IMPLEMENTATION METHODS

[0022] 1) Outdoor Installation:

[0023] A) When the frames of a house, stadium, conservatory, etc. have been constructed, structure A and structure B described in the previous text can be installed onto the frames. According to the thermal expansion coefficient of the hollow sheet's material, the diameter of bolt hole 5 in FIG. 1 needs to be bigger than the diameter of bolt and has enough space for the hollow sheet's displacement caused by thermal expansion. At the same time, the bolt nut needs to have a gasket or blocking plate with a dimension bigger than the bolt hole (otherwise the bolt would not be able to fix the hollow sheet). Also, between two neighboring hollow sheets there shall be set a space enough for their expansion. In these respects there are already a lot of experiences and techniques for reference. The difference here is that the energy-saving hollow sheet may be much thicker than the traditional one, so bolts of corresponding lengths need to be fixed to the building's frame through bolt nuts, welding, etc.

[0024] B) For convenience of the hollow sheet's installation and replacement, when it is installed outdoors, its rain-proofing can be done as follows:

[0025] a) When the hollow sheet is installed vertically or obliquely (usually as a wall it is installed vertically; as a roof it is installed obliquely), at where the upper and lower hollow sheets connect, the section in FIG. 4 can be applied: At the lower brim of upper hollow sheet 1 there is set a covering plate 2. If covering plate 2 needs to be made stronger, ribs 3 can be set on it at intervals. Covering plate 2 can cover the upper brim of lower hollow sheet 4, so that the rain cannot enter the space between hollow sheet 1 and 4. The bigger width of covering plate 2, the better function of rain-proofing. During installation, lower hollow sheet 4 needs to be installed before upper hollow sheet 1. When the above covering plate is applied on the roof, the roof cannot be set level, but should have a slope (Angle of this slope shall be determined according to the maximum rainfall of the area).

[0026] b) The connection of left and right hollow sheets can be done as in the top view of FIG. 5: Rain cover 1 is fixed by bolt 2 to the building's frame (For rain-proofing of the bolt hole in the rain cover, see section c in the following text); Hollow sheets 3,4 have rain-proofing plate 5,6 respectively; Between hollow sheets 3,4 there is enough space for expansion; When the hollow sheets expand or shrink, rain-proofing plates 5,6 can move within the space under rain cover 1; Rain cover 1 and rain-proofing plates 5,6 can prevent the rain from entering the space between hollow sheets 3,4. The shape of rain cover 1 has some resemblance to the U-shaped locker of current techniques. The difference is that the U-shaped locker can be locked onto the curved edge of two neighboring hollow sheets while the hollow sheets at the two sides of rain cover 1 have no curved edge and the rain cover cannot be locked. Furthermore, the hollow sheets can freely move under the rain cover, and inside the rain cover there needs to be set an insulating layer to reach the same insulating level as the hollow sheets.

[0027] During installation, the upper rain cover shall be aligned with the lower rain cover, and at the lower brim of the upper rain cover there shall be set a covering plate, which covering plate shall cover the upper brim of the lower rain cover, in a similar way to the connection of upper and lower hollow sheets. If under special circumstances the upper and lower rain covers cannot be aligned, then at the upper end of the rain cover there needs to be set a slant plate, which slant plate needs to be connected to under the covering plate of the hollow sheet above it; At the same time, at the lower end of the rain cover there needs to be set a covering plate to cover the upper brim of the hollow sheet under it.

[0028] c) Rain-proofing of the bolt hole can be done as in FIG. 6: Bolt 1 is fixed to the building's frame; Rain-proofing ring 2 (which can be made with the same material as the hollow sheet) is fixed by welding or gluing on hollow sheet 3 (or on a rain cover) around bolt hole 4; The diameter of rain-proofing ring 2s bottom is smaller than its top so that the rain running on hollow sheet 3 cannot enter the rain-proofing ring; Near the top of bolt 1 there is set stopping panel 7 which is fixed by bolt nuts 5,6; Stopping panel 7 and the supports under hollow sheet 3 can prevent hollow sheet 3 from vertically moving, but allow it to move horizontally (Inside rain-proofing ring 2 there is space, so bolt 1 is not wrapped by rain-proofing ring 2. Therefore, although hollow sheet 3 is connected to rain-proofing ring 2 to form one body, hollow sheet 3 can still move in the front-back and left-right directions); Stopping panel 7 needs to cover rain-proofing ring 2, and on bolt nut 6 there must be installed insulating cover 8 and rain-proofing cap 9 (They may be fixed by glue if necessary); Rain-proofing cap 9 can prevent the rain from entering the bolt hole at the middle of stopping panel 7; Stopping panel 7 can prevent the rain from entering rain-proofing ring 2; Thus the rain would not be able to enter the bolt hole in hollow sheet 3.

[0029] C) With structure A described in the previous text (see FIG. 1), the cavities are closed. When the ambient temperature changes, the difference of air pressure can make the hollow sheet convex or concave. If the cavities are opened to the outside, then the vapor may mist the cavities, affecting its function of transparency. To solve this problem, the cavities can be connected to air-bags: When the cavities are heated, the expanded air would be discharged into the air-bags; When the cavities are cooled, the air in the air-bags would be sucked into the air-bags. If the cavities are filled with inert gas, its thermal insulating function can be further improved. With structure B described in the previous text (see FIG. 3), the cavities can be set as half-closed: When there is a difference of air pressure, the air can move into or out of the cavities through small holes or filtering panels; When there is no difference of air pressure, the air would not move into or out of the cavities.

[0030] D) For highly energy-saving buildings, if the energy-saving hollow sheets are installed outdoors, the frame of building should be totally covered by the hollow sheets, avoiding as much as possible that any part be uncovered. Also, the bolt nuts on the hollow sheets and the part of bolts protruding above the hollow sheets shall be securely covered by insulating caps or sheaths, with structural adhesive used if necessary. Adjacent hollow sheets must be sealed: Between the hollow sheets and the frame of building there shall be installed gasket of neoprene etc., so that the hollow sheets can move but keep being sealed. At the inner side of the outermost panel in the hollow sheet there shall be added a anti-thermal-radiation and anti-ultraviolet coating (This coating can also be added at other layers of panel. But it shall be avoided to make the coating on the hollow sheet's surface, so as to avoid that the coating be scared or fall off). The hollow sheet's fire rating and content of hazardous substances, etc. must also meet the related standards.

[0031] 2) Indoor Installation:

[0032] A) Single-storey Building

[0033] When installing the hollow sheets indoors for a single-storey building, the methods are similar to that of outdoor installation described above. The differences are:

[0034] a) When the hollow sheets are installed as the roof, they are hung under the frame of the roof with the bolts pointing downward. Rain-proofing needs to be done near the root of the bolts to prevent that the rain flow along the bolt into the room. When the hollow sheets are installed as the external wall, the bolts point inward, and rain-proofing also needs to be done near their root. The rain-proofing can be done as in FIG. 7: Near the root of bolt 1 is set a spherical surface 2; The top of stopping panel 3 is set as a convex; At the root of this convex there is a rain groove 4. Push Stopping panel 3 to spherical surface 2 and use bolt nut 5 to make it fixed. At the same time, on hollow sheet 6 set rain-proofing ring 8 around bolt hole 7 (in the same way as in FIG. 6). Then push hollow sheet 6 upward to let bolt 1 enter bolt hole 7. Next add gasket and bolt nut at the lower end (or the inner end) of bolt 1, so that hollow sheet 6 would be fixed under the frame of roof (or inside the frame of external wall), and the rain would be prevented from entering bolt hole 7. At the lower end or inner end of bolt 1 there shall be installed a insulating cap.

[0035] b) When the hollow sheets are installed as the external wall, every upper row of hollow sheets shall be installed before the lower row. Otherwise, the lower row would block the covering plate of the upper row (see FIG. 4) .

[0036] c) When the rain cover (see FIG. 5) is installed between the neighboring left and right hollow sheets, the rain cover shall be installed first (at this time the direction that the bolt points in is opposite to that in FIG. 5, and is the same as the direction of the bolt in FIG. 7). Then the hollow sheets at the two sides shall be installed (This order of installation is the inverse of that with outdoor installation).

[0037] d) With single-storey buildings, when the hollow sheets are installed indoors, they do not need to cover the frame of building, so different visual effects can be created, yet their thermal insulating performance won't be second to that of outdoor installation.

[0038] B) Multiple-storey Building

[0039] For multiple-storey buildings, indoor installation is more significant, because replacement of the hollow sheets, which have a relative short service life, is much more easily and safely carried out indoors than outdoors on the higher floors of the building. For indoor installation and replacement of hollow sheets on multiple-storey buildings, on the basis of the methods with single-storey as described above, the following adjustments need to be made:

[0040] a) Based on the patent mentioned in the previous text, in FIG. 8, outside a multiple-storey building's floor there shall be installed connecting rods 1,2 (Due to the light weight of hollow sheet, these connecting rods do not need to be directly pre-embedded in the concrete frame of building, but can be fixed onto relatively sparse pre-embedded bolts etc.). Connecting rods 1,2 are respectively inserted in the bolt holes of upper hollow sheet 3 and lower hollow sheet 4; Their rain-proofing can be done as per what's described above (see Indoor Installation Aa). The curved shape of the connecting rods can further prevent the rain from entering the room.

[0041] b) Based on the patent mentioned in the previous text, in FIG. 9, outside a multiple-storey building's floor there shall be installed insulating block 1; At the top and bottom of insulating block 1's inner side there shall be respectively set rain-proofing plates 2, and a covering plate 3. At the same time, on upper hollow sheet 4 there shall be set covering plate 5 through gluing, welding, etc.; Covering plate 5 shall be set at the same height as the top of rain-proofing plate 2 and its lower brim shall be elastic and lower than the top of rain-proofing plate 2. During installation, insulating block 1 shall be installed first; Then install the upper and lower hollow sheets. When installing the upper hollow sheet, its bolt hole shall be put onto the connecting rod (see description in the previous paragraph), then it shall be pushed outward till the lower brim of covering plate 5 is pushed against the top of rain-proofing plate 2 and is bent. Then continue with the outward pushing till covering plate 5 surpasses rain-proofing plate 2 and its lower brim restores the original shape, so that the rain would not be able to flow into the space between the hollow sheet and the insulating block. When the hollow sheet has been pushed to the limit, install gasket, bolt nut, and insulating cap at the end of the bolt. The bigger width of covering plate 5 and its lower brim, the better function of rain-proofing. But the rigid part of covering plate 5 needs to be set at a position a little higher than the top of rain-proofing plate 2; Otherwise covering plate 5 might not be able to surpass rain-proofing plate 2 smoothly or might cause damage. At the same time, the bottom of covering plate 5's rigid part shall be set slanting outward, so shall the top of insulating block 1's top be set. In this way, their function of rain-proofing can be further improved. When removing the hollow sheet, the insulating cap, bolt nut, and gasket shall be removed first; Then pull the hollow sheet inward (On the inner side of the hollow sheet there shall be set handles for the pulling).

[0042] At position of the connecting rods described above (at part a), the insulating block described in the previous paragraph needs to be made wider and thicker (If the connecting rods are horizontally close to each other, the whole insulating block may be made wider and thicker) with space set at its inner side, so that the connecting rods can be covered (see the front view in FIG. 10: Insulating block 1 needs to be made wider and thicker at the connecting rods' positions 1a, 1b). At the same time, the insulating block's rain-proofing plate 2 and the covering plate of the hollow sheet above it shall be set along its side line 3 (see the front view in FIG. 10). At position of the side line's vertical part 3a, there shall be set on rain-proofing plate 2 a brim 3b pointing outward (see the enlarged top view in FIG. 11), so that the rain would be prevented from flowing to the inside.

[0043] At where the horizontal insulating block and the vertical rain cover meet (see Outdoor Installation Bb and FIG. 5), vertical rain cover 1 can bend outward (see the side view in FIG. 12 and the front view in FIG. 13), so that it can cover insulating blocks 2,3 at its two sides.

[0044] c) The rain cover described in the previous text (see Outdoor Installation Bb and FIG. 5) needs to be installed at the outside of the building's vertical frame (Because the vertical frame has only a limited width, the installation can still be done indoors. See the top view in FIG. 14, wherein rain cover 2 is installed outside frame 1). On a same floor, installation of the rain cover need to be done prior to that of the hollow sheet. And, as in FIG. 14, according to the width of the building's vertical frame 1, rain cover 2 needs to have adjustments accordingly, so that it can surpass frame 1 at the two sides and hollow sheets 3, 4's rain-proofing plates 5, 6 can move in the space at the inner side of rain cover 2.

[0045] d) On the top floor of a multiple-storey building, installation and replacement of the hollow sheets for the roof can be directly done indoors.

[0046] e) Based on the technology of the patent mentioned in the previous text, at the edge of the floor of and above the second storey there must be installed safety railing or safety net (If the hollow sheet has a panel strong enough and is installed securely enough, then the safety railing or net may be canceled). At positions with Anti-burglary requirement, there shall be installed anti-burglary net. On every hollow sheet, insulating block, rain cover, etc. there must be moulded the time of production, and they must be replaced in time.

[0047] f) This energy-saving hollow sheet can also be used as partition wall inside the building. With the cancel of spacing bars, its sound-insulating function can improved.

[0048] 3) Application of Energy-saving Hollow Sheet

[0049] The energy-saving hollow sheet used on multiple-storey buildings has a weight times lower than glass curtain wall, yet has higher strength and lower risk of breakage or falling off. Therefore, it can significantly increase the overall height of a building, and can be widely applied on residential buildings, office buildings, hotels, etc., resulting in higher efficiency of land use and further-decreased price of housing.

[0050] When the energy-saving hollow sheet is applied on houses with frame of reinforced concrete, as the bearing wall is canceled, to ensure the house's anti-seismic function, the horizontal beam's span must not be set too long, and shear walls or counter-shear structures shall be set. If steel structure is selected for the house's frame, its anti-seismic function can be improved. With whatever type of structural frame, an ordinary high-rise building must not be designed to look like a pen. Otherwise its foundation would not suffice to resist the horizontal wave in a earthquake. Only when the ratio of the building's area of foundation to its height is made large enough, and proportion of the building's length and width are suitable, avoiding narrow and straight types whose shape in top view is like the longitudinal section of a stick, and applying the types with shape of a square, a cross, etc. in top viewcan the building's anti-seismic function be assured.

[0051] When the energy-saving hollow sheet is applied on various types of building, any level of thermal insulation can be achieved, and the problem of energy-saving can be fundamentally solved, resulting in the comprehensive benefits in the long run.
