Description

Technical Field

[0001] The utility model relates to the field of shear walls, in particular to a shear wall formwork reinforcement device. Background Art

[0002] Shear walls are also called wind-resistant walls, earthquake-resistant walls or structural walls. They are walls in houses or structures that mainly bear horizontal and vertical loads caused by wind loads or earthquakes to prevent structural shear damage. They are generally made of reinforced concrete.

[0003] When the existing shear wall is constructed by formwork casting, wooden formwork is generally used in combination with water-stop screws to fix the formwork and cast concrete. However, when the wooden formwork is used, holes need to be punched for the installation and use of the water-stop screws. Therefore, the punching position of the wooden formwork will cause the formwork to crack, and leakage will occur in the later construction. At the same time, due to the cracking of the holes, the overall performance of the formwork is damaged, affecting its multiple uses in the later period. When the traditional water-stop screws are used, it is necessary to cut off the excess materials after casting and forming, which is not conducive to the reuse of materials.

[0004] Therefore, a new type of shear wall formwork reinforcement device is needed to meet the usage requirements. Utility Model Content

[0005] In view of this, the shear wall formwork reinforcement device of the utility model converts the traditional whole formwork into a block-type formwork by punching holes to install tension screws, and adopts thick steel plates at the positions where holes need to be punched to install tension screws, thereby avoiding the cracking of the traditional formwork due to punching holes, which affects the flatness of the overall formwork and facilitates later reuse. At the same time, a three-stage water-stop screw is adopted, which is convenient for disassembly and recycling of the screw after casting and forming. At the same time, the setting of positioning tubes and transverse support rods effectively ensures the structural strength during casting.

[0006] A shear wall formwork reinforcement device includes a formwork assembly attached to the shear wall, a positioning tube used in conjunction with the formwork assembly, and a waterstop screw assembly used in conjunction with the positioning tube; the formwork assembly includes a plurality of film formworks spaced in sequence along the vertical height direction of the shear wall and a thick steel plate arranged between adjacent film formworks, and the waterstop screw assembly locks the film formworks and the thick steel plate after being fixedly installed.

[0007] Furthermore, it also includes a transverse support rod arranged along the length direction of the shear wall, the transverse support rod and the positioning tube are arranged perpendicular to each other, the transverse support rod is installed on the outer surface of the positioning tube, and the water stop screw assembly locks the transverse support rod and presses the positioning tube.

[0008] Furthermore, the thick steel plate is provided with a plurality of steel plate mounting holes along the length direction of the shear wall, and the waterstop screw assembly includes an intermediate screw, two end screw groups with the same structure, and a waterstop plate used in conjunction with the intermediate screw, and the waterstop screw assemblies are installed at the plurality of steel plate mounting holes.

[0009] Furthermore, there are multiple positioning tubes and the multiple positioning tubes are evenly spaced and distributed along the length direction of the shear wall. The positioning tubes are steel tubes with rectangular structures, and the steel plate mounting holes are arranged between two adjacent positioning tubes.

[0010] Furthermore, the transverse support rods are provided in multiple groups and the multiple groups of transverse support rods are evenly arranged along the vertical direction of the shear wall.

[0011] Furthermore, the transverse support rod includes an upper support rod and a lower support rod with the same structure, and the water-stop screw assembly simultaneously locks the upper support rod and the lower support rod and achieves compression of the positioning tube.

[0012] The beneficial effects of the utility model are as follows: the shear wall formwork reinforcement device disclosed in the utility model converts the traditional whole-piece formwork into a block-type formwork method by punching holes to install tension screws, and adopts thick steel plates at positions where holes need to be punched to install tension screws, thereby avoiding cracking caused by punching holes in the traditional formwork and affecting the flatness of the overall formwork, which is convenient for later reuse.

As shown in the figure, a shear wall formwork reinforcement device includes a formwork component attached to the shear wall, a positioning tube 6 used in conjunction with the formwork component, and a waterstop screw assembly 3 used in conjunction with the positioning tube 6; the formwork assembly includes a plurality of film formworks 2 distributed in sequence along the vertical height direction of the shear wall and a thick steel plate 4 arranged between adjacent film formworks, and the waterstop screw assembly is fixedly installed to lock the film formwork 2 and the thick steel plate; the shear wall formwork reinforcement device disclosed in the utility model converts the traditional whole-piece formwork into a block-type formwork method by punching holes to install tension screws, and adopts a thick steel plate method at the position where the tension screws need to be punched to install, thereby avoiding the traditional formwork from being cracked due to punching holes, affecting the flatness of the overall formwork, and facilitating later reuse. At the same time, a three-stage waterstop screw is adopted, which is convenient for disassembly and recovery of the screw after casting and forming. At the same time, the positioning tube and the horizontal support rod are arranged to effectively ensure the structural strength during casting.

[0017] In this embodiment, a transverse support rod is also arranged along the length direction of the shear wall. The transverse support rod and the positioning tube 6 are arranged perpendicular to each other. The transverse support rod is installed on the outer surface of the positioning tube 6 (such as Figure 1 The left and right sides of the shear wall 1 are the outside), and the water-stop screw assembly locks the transverse support rod and presses the positioning tube. The transverse support rod is locked by the water-stop screw assembly 3 and then pressed against the outer side of the positioning tube 6 to form an overall positioning support effect. A thick steel plate 4 is arranged between two adjacent film formworks 2 for positioning and installing the water-stop screw assembly 3. The film formwork 2 can be made of wood or other plates with good flatness.

[0018] In this embodiment, the thick steel plate 4 is provided with a plurality of steel plate mounting holes along the length direction of the shear wall, and the water-stop screw assembly includes an intermediate screw, two end screw groups with the same structure, and a water-stop sheet 31 used in conjunction with the intermediate screw, and a plurality of the steel plate mounting holes are provided with water-stop screw assemblies. The water-stop screw adopts a three-stage water-stop screw, which is convenient for later disassembly and reuse, and avoids material waste (here is a three-stage water-stop screw in the prior art, which will not be described in detail). The thick steel plate 4 is punched to avoid inaccurate positioning of the punching holes in the later stage, and the traditional wooden formwork will crack when the holes are punched. The thick steel plate 4 is used at the location where the stress is concentrated, which is also conducive to a more stable and reliable overall structure.

[0019] In this embodiment, there are multiple positioning tubes 6 and the multiple positioning tubes are evenly spaced along the length direction of the shear wall. The positioning tubes 6 are rectangular steel tubes, and the steel plate mounting holes are set between two adjacent positioning tubes.

The multiple groups of transverse support rods 5 are evenly distributed according to the height of the shear wall 1 to improve the overall structural performance.

[0021] In this embodiment, the transverse support rod includes an upper support rod 5 and a lower support rod 51 of the same structure, and the water-stop screw assembly simultaneously locks the upper support rod 5 and the lower support rod 51 and realizes the compression of the positioning tube. The locking member of the water-stop screw assembly just locks a group of support rods, which has better structural performance.
