Concrete anchor
An anchor for supporting a load includes an anchor rod having a first threaded end portion for being embedded in a concrete structure and a second end portion for attachment to a load; a metallic wedge-shaped body attached to the first threaded end portion; and the body includes a circular cross-section, a circular top surface and a circular bottom surface joined by a side surface.
Structure for joining column and beam frame and shear wall
In between a shear wall of a reinforced concrete structure disposed in a column and beam frame of a reinforced concrete structure and the frame, transmission capability of a shear force between is enhanced from a stage which a relative deformation occurs among between the frame and the shear wall. Plate is disposed between an inner peripheral surface of a frame and an outer peripheral surface of a shear wall, integrated with any one of the frame and the shear wall, and continuous in a longitudinal direction and in a height direction of the shear wall and penetrate the plate in a thickness direction. The anchors are dispersedly in the longitudinal direction and in the height direction of the shear wall.
Lift anchor for precast concrete component
A precast concrete component is provided with anchor having a cylindrical rod bent to form a centrally-positioned handle and two downwardly extending legs. The handle can be relatively smooth and die legs are provided with a series of projections along their lengths, such as are formed by threads. The legs of the anchor may converge inwardly from the handle and are compatible with precast concrete double tees having webs or stems that taper from the flange of the double tee downward. Alternatively, the legs of the anchor may diverge outwardly from the handle.
STRUCTURE FOR JOINING COLUMN AND BEAM FRAME AND SHEAR WALL
In between a shear wall of a reinforced concrete structure disposed in a column and beam frame of a reinforced concrete structure and the frame, transmission capability of a shear force between is enhanced from a stage which a relative deformation occurs among between the frame and the shear wall. Plate is disposed between an inner peripheral surface of a frame and an outer peripheral surface of a shear wall, integrated with any one of the frame and the shear wall, and continuous in a longitudinal direction and in a height direction of the shear wall and penetrate the plate in a thickness direction. The anchors are dispersedly in the longitudinal direction and in the height direction of the shear wall.
METHOD AND ARRANGEMENT FOR SUPPORTING A FLOOR ELEMENT ON A BEAM AND BEAM
A method and an arrangement for supporting a first floor element at a beam and a beam. The beam is provided with a supporting flange section configured to support the first floor element. The method includes supporting the first floor element on the supporting flange section so that a first space is formed between the first floor element and the beam, providing elongated transverse fittings in the beam, providing transverse reinforcements to extend between the beam and the first floor element. The elongated transverse fitting have a first free end at the first lateral side of the beam, and a first protective element is connected to the first free end of the elongated transverse fitting outside the web section of the beam.
CONCRETE FASTENER INSTALLATION USING LOW VISCOSITY ADHESIVE
A method for installing fastener in a base material. The fastener has a shank having a first end and a second end defining a length, a head provided at the second end, and a thread provided on the shank which includes a leading edge and a trailing edge adapted remove portions of the base material when inserted into the base material. The method includes forming a hole having a diameter which is a nominal shank diameter of the fastener to be installed in the base material. The hole is then filled with an adhesive having a viscosity of 350 cP or less. Finally, the fastener is rotated into the hole such that the adhesive is forced into portions of the base material adjacent to the shank and thread when the thread is fully inserted into the hole.
Anchor bolt for adhesive anchor, adhesive anchor, and method for constructing adhesive anchor
An anchor bolt for an adhesive anchor or the like that can be caused to exert substantial tensile strength at a relatively shallow embedding depth. An anchor bolt for an adhesive anchor that is fixed via adhesive to an anchor hole formed in a fixed body includes: a head part that is inserted into a hole back part of the anchor hole; a shank part that is continuous with the head part and formed to have a diameter smaller than the diameter of the head part; and a sleeve part into which the shank part is inserted, the sleeve part extending from an opening part to the hole back part of the anchor hole and having a tip end thereof abutted onto the head part.
Clamper plate
A clamper plate for securing a tower having a flange to a pedestal having an embedded first bolt and second bolt is disclosed. The clamper plate includes a first surface coming into contact with the flange and a second surface coming into contact with the pedestal. The clamper plate also includes a first through-hole for receiving the first bolt therethrough and a second through-hole for receiving the second bolt therethrough. During installation the clamper plate is placed over the flange and secured to the pedestal through the first bolt and second bolt.
HOLD DOWN SYSTEM WITH DISTRIBUTED LOADING FOR BUILDING WALLS
A hold down system for a building wall comprises a first rigid member and a second rigid member, the second rigid member being vertically spaced apart from the first rigid member, the first rigid member is supported on a horizontal member of a stud wall, the first and second rigid members including first and second openings, respectively; a tie-rod with a lower end portion for being anchored to an anchorage, the tie-rod extending transversely through the first and second openings, the tie-rod dividing the first and second rigid members into a first lateral section on one side of the tie-rod and a second lateral section on a diametrically opposite side of the tie-rod; first support and second support disposed between the first and second rigid members, the first support being disposed in the first lateral section, the second support being disposed in the second lateral section, the tie-rod extending through the first and second rigid members outside of the first support or the second support; and a nut threaded to the tie-rod, the nut exerting pressure on the second rigid member to place the tie rod under tension loading, the tension loading is transferred by the second rigid member to the first and second supports to subject the first and second supports to compression loading, thereby causing the first rigid member to press on the horizontal member of the stud wall via the first and second lateral sections of the first rigid member, thus distributing the compression loading.
COMPRESSION AND TENSION REINFORCED WALL
A reinforced building wall includes a foundation and an anchor rod anchored to the foundation; a first stud wall disposed above the foundation; the first stud wall having a first bottom plate, a first top plate and first and second vertical studs operably joined to the first bottom plate and the first top plate; a horizontal first bridge member disposed between the first stud and the second stud, the first bridge member having a first vertical opening; a rod post having one end operably connected to the anchor rod and operably connected to the first bridge member to transfer downward forces from the first bridge member and the second bridge member to the rod post; the anchor rod is attached to an anchor; and the anchor is disposed in an upper portion of the foundation.
