Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a cantilever casting formwork bracket. Background Art

[0002] A cantilever is a part of a building that is suspended outside a support and is not supported by the ground. It is usually made of poured concrete. During construction, according to the weight and shape of the cantilever structure, a formwork support is first built, and then the cantilever formwork is laid on the formwork support. The cantilever formwork is supported by the formwork support to ensure that the formwork can withstand the weight and pressure of the poured concrete.

[0003] Some existing formwork supports are usually anchored to the wall by bolts, which is more suitable for concrete walls. However, some existing buildings use hollow brick masonry brick wall structures. The anchor point when the bolt is anchored into the wall may coincide with the brick, that is, the anchor hole is opened on the brick, and the hollow brick is limited by its own structure and it is difficult to bear a large ballast load. When the load generated during the pouring of the cantilever structure is transmitted to the hollow brick through the bolt, it may cause the hollow brick to be crushed and damaged, and then cause the formwork support to shift. Even the existing bracket installation method will make the installation of the formwork support insufficiently stable, which is not conducive to practical use. Utility Model Content

[0004] The utility model aims to provide a cantilever casting formwork support to solve the above-mentioned problem of insufficient installation stability of the existing formwork support.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions: a cantilever casting formwork support, installed on the wall, including

[0006] A pull plate is inserted through the wall and located between the bricks of the wall, one end of the pull plate is provided with a plug hole, and the other end of the pull plate is provided with a latch slot;

[0007] The latch piece is wedge-shaped in appearance, inserted into the latch groove, and abutted against the wall;

[0008] The bracket plate group has hooks arranged on its side walls, the hooks are inserted into the insertion holes, the pull plate abuts against the bracket plate group, and the bracket plate group abuts against the wall.

[0009] The principle and effect of this technical solution:

[0010] 1. During the construction of brick concrete houses, the mortar thickness between the upper and lower adjacent bricks is usually between 10-20mm. During the masonry, wooden strips are embedded between the bricks (the thickness of the wooden strips does not exceed the gap between the upper and lower adjacent bricks, so as not to affect the construction of the upper bricks. Bricks are usually built in a staggered manner. By controlling the width of the pull plate, the pull plate does not completely overlap with the bricks, thereby ensuring the strength of the wall during construction), so as not to affect the construction of the wall. After the masonry is completed, when the cantilever formwork is installed, the embedded wooden strips are knocked out of the masonry. When a cavity appears on the masonry, the pull plate is inserted into the cavity, and the bracket plate group is abutted against the wall through the hook and plugged into the pull plate, so that the bracket plate group can be tightened on the wall through the pull plate, and then the pin piece is knocked into the plug groove and pressed against the wall, and the different lengths of the pin piece and the plug groove are matched to adapt to different wall thicknesses (when the thickness is larger, the length of the pin piece passing through the pin groove is smaller, and when the thickness is smaller, the length of the pin piece passing through the pin groove is larger). After the cantilever pouring is completed, the wall can be restored by removing the pull plate and filling with mud to have the required strength.

[0011] 2. The setting of the bracket plate group is installed by the pull plate, which is easy to disassemble and assemble without damaging the structural strength of the wall; and compared with the bolts, the pull plate has a larger projection area, which can reduce the load applied to the unit area of ​​the brick, avoid brick fracturing and damage, and improve the installation stability of the formwork bracket.

[0012] The utility model is further configured as follows: the bracket plate group includes a horizontal support plate, a vertical support plate and an oblique support plate, the hooks are fixed on the side walls of the vertical support plates, and multiple hooks are arranged at intervals along the vertical direction, the vertical support plates are abutted against the wall, the horizontal support plates are installed on the top of the vertical support plates, one end of the oblique support plates is connected to the vertical support plates, and the other end of the oblique support plates is connected to the horizontal support plates.

[0013] The principle and effect of this technical solution: a triangular support structure is formed by setting up horizontal braces, vertical braces and diagonal braces, so that the pressure of the concrete poured on the top can be partially offset by the friction generated between its own weight and the wall, thereby reducing the pressure that the anchoring structure or the fixed structure needs to bear.

[0014] The utility model is further configured as follows: the horizontal bracing plate, the vertical bracing plate and the diagonal bracing plate are welded and connected.

[0015] The principle and effect of this technical solution: through welding connection, the horizontal brace plate, the vertical brace plate and the diagonal brace plate form a whole without disassembly, and the overall installation is more convenient and has strong stability.

[0016] The utility model is further configured as follows: an assembly screw is fixed on the top of the vertical support plate, the assembly screw passes through the horizontal support plate, and a nut is threadedly mounted on the threaded sleeve; pressure plates are respectively fixed at both ends of the oblique support plate, and connecting bolts are passed through the two pressure plates, and the two connecting bolts are respectively threadedly inserted into the side wall of the horizontal support plate and the side wall of the vertical support plate.

[0017] The principle and effect of the technical solution: the setting of the assembly screw rods, nuts, pressure plates and connecting bolts makes the vertical bracing plates, horizontal bracing plates and diagonal bracing plates detachable as a whole, which is convenient for transportation and carrying.

[0018] The utility model is further configured as follows: a reinforcing plate with an I-shaped appearance can be detachably installed on one side of the oblique bracing plate close to the wall, and the reinforcing plate is respectively abutted against the horizontal bracing plate and the vertical bracing plate.

[0019] The principle and effect of this technical solution: the setting of the reinforcement plate can distribute the pressure on the diagonal brace plate, and through the abutment between the reinforcement plate, the transverse brace plate and the vertical brace plate, the pressure on the transverse brace plate can be transmitted through the vertical brace plate, thereby reducing the pressure on the diagonal brace plate and further improving the pressure-bearing capacity of the diagonal brace plate.

[0020] The utility model is further configured as follows: a convex edge is provided on the top of the vertical support plate, the convex edge is located at a side of the vertical support plate away from the wall, and the convex edge is in contact with the horizontal support plate.

[0021] The principle and effect of this technical solution: the setting of the convex edge can expand the contact area between the horizontal brace plate and the vertical brace plate, so that the pressure of the horizontal brace plate on the vertical brace plate is more uniform and stable, and the connection between the horizontal brace plate and the vertical brace plate is more stable.

[0022] The utility model is further configured as follows: a plurality of adjusting screws are arranged at intervals on the top of the cross bracing plate; an adjusting sleeve is threadedly sleeved on the adjusting screw; and a placing plate is fixed on the top of the adjusting sleeve.

[0023] The principle and effect of this technical solution: the setting of the adjusting screw, the adjusting sleeve and the placing plate allows the height of the placing plate to be adjusted. By adjusting the height of the placing plate, the height of the casting template placed on the bracket can be adjusted to adapt to assembly errors and installation errors.

[0024] The utility model is further configured as follows: a retaining edge is installed at one end of the top of the cross brace plate away from the wall.

[0025] The principle and effect of the technical solution: the setting of the retaining edge can shield the edge of the template, thereby improving the stability of the template when placed on the bracket. BRIEF DESCRIPTION OF THE DRAWINGS
