Description

BRIEF DESCRIPTION OF DRAWINGS

[0014] FIG. 1 is bolt-type connection.

[0015] FIG. 2 is steel-bar-type connection.

[0016] FIG. 3 is drainage and inspection hole.

IMPLEMENTATION WAYS FOR THIS INVENTION

[0017] 1) Connection

[0018] With both the bolt-type and steel-bar-type connections, rustable steel or iron products need to be galvanized. Diameter of steel bars and their distance to each other shall guarantee that in earthquake enough tensile resistance and compressive resistance be provided by them. According to thickness of joints between the bricks, diameter of the steel bars can be as thick as possible with enough mortar above and under them. The horizontal distance between two steel bar connectors can be around 50 cm (reference value. In practice it shall be based on structural calculations).

[0019] With the bolt-type connection, as in FIG. 1, if height of concrete block 2 is great, bolt 3 will correspondingly be long. At this time two steel bars B can be put around bolt 3 and be buried to the joints above and under concrete block 1 respectively, each of them being near to the two ends of bolt 3. In this way the whole tensile and compressive strengths will be boosted and distances between the bolts can be increased (but the average distance between steel bars need to be kept the same), thus number of the bolts can be reduced to save material.

[0020] With the steel-bar-type connection, as in FIG. 2, the two semicircle-shaped steel bars 3 are put together to form an X shape (the middle section of both the bars needs to be made straight: if the middle section is bent, the strength will be greatly reduced) and are buried together. The two steel bars can also be bent to the shape of a square bracket and be put back to back forming a I shape for burying (the X-shaped bars are a little stronger than the I-shaped bars). If the above pairs of steel bars are welded together, the strength can be further increased. If a single steel bar is bent to form a square with the ends welded together, and with two opposite sides of the square buried into the joints of face bricks and concrete blocks respectively, the strength can also be kept. Otherwise, if the steel bars are not buried in pairs and symmetry of the above modes, whatever shape a single bar is bent into, the strength will be decreased.

[0021] In the two types of connection above, the bolt can have various shapes and may not necessarily have screw on it; the nut can be replaced by a pin or other obstacles that can prevent the steel bars from slipping out of the bolt; the X-shaped bars, I-shaped bars, and square bar can be cast products or other metal products. Whatever shape and material, the principles and modes will be the same.

[0022] 2) Insulation

[0023] For buildings with higher insulation requirements, an insulation layer ought to be put between the face brick and concrete block. As there are connectors of bolt or steel bar between the two wythes, loose insulation fiber may be easier to install; If insulation sheets are to be used, slits can be made at positions of the connectors.

[0024] The distance between face brick and concrete block need to be as near as possible to save space as well as the amount of steel bars and insulation fiber. However, if the concrete block and face brick themselves cannot provide enough function of insulation, the distance between them needs be increased, so does the amount of insulation fiber.

[0025] 3) Service Life

[0026] The appearance of brick wall will not be affected much by time, and may even look more charming with age (the bricks of the Great Wall still do not look old today). If qualified inorganic insulation fiber is used and the steel bars and bolts are hot-galvanized properly, then the above external wall of face brick can last at least 100 years. If the cavity between the face brick and the concrete block is sealed with sealant (but drainage holes ought to be set at the bottom in case water enters the cavity), at the same time, a suitable amount of calcined lime is put in the cavity (which can absorb excessive moisture in the air left in the early stage), and moisture filtering materials are put at the drainage and air-flowing holes (which can prevent moisture but allow an amount of air to flow due to change of temperature), then all the functions of the external wall can be protected better and the service life can be prolonged. If conditions are ready for using stainless steel instead of the above galvanized steel bar and bolt, the service life may be regarded as permanent.

[0027] 4) Safety Inspection

[0028] During the process of laying concrete blocks, at the bottom of each wall a gap can be reserved for installation of the drainage and inspection hole. As FIG. 3 shows, drainage and inspection hole 1 is reserved at the lowest layer of block 2 and has the same height as it; when the drainage pipe (or drainage channel etc.) is installed, the rest of the hole will to be blocked. The blocking material needs to be removable. When inspection is to be done, the blocking material will be removed and inspecting devices can be put into the cavity. Size of the inspection hole needs to allow passage of a inspecting mirror or other devices.

[0029] Conditions of the steel bars, bolts, insulation fibers, etc. need to be inspected periodically, so that an accurate assessment can be made on the whole external wall.

INDUSTRIAL APPLICABILITY

[0031] For energy-saving, this face brick external wall has two wythes plus an insulating layer, and thickness of the insulating layer can be freely set. Hence it can satisfy the highest requirement for thermal insulation in all areas, and save a huge amount of energy for temperature control of houses. Compared to the current curtain walls that have not good performance in thermal insulation, this face brick external wall can improve the insulating performance for more than 10 times; Compared to concrete wall or brick wall, its insulating performance can also be times higher.

[0032] For appearance of buildings, this face brick external wall has a particular primitive style, and its hollow face brick can make a more natural effect than decorative tiles. This style plays an irreplaceable role in the planning of urban and suburban development, and is able to bring abundant visual effects. However, now its proportion is extremely low, forming a vacancy for development. In architectural planning and design, its models and renderings can express most of the real effects, making an advantage in bidding of related projects.

[0033] In terms of construction cost, this face brick external wall's how brick, concrete block, and insulating sheet are each just dozens CNY per square meter; the connectors of a bolt or two and steel bars for each square meter also cost very low. In comparison to curtain walls that need hundreds or more than a thousand CNY for a square meter to be built, this face brick external wall's cost is many times lower.

[0034] For construction, the techniques for this face brick external wall are not complicated. Across the country there are still many technicians with good command of brick laying. Training for people is also not difficult.

[0035] In conclusion, application and promotion of this face brick external wall can bring a big economic benefit and long term comprehensive benefits for architectural units, urban and suburban planning units, construction units, real estate development companies, and the vast number of users.
