Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a cantilever casting formwork support. Background Technology

[0002] A cantilever refers to a part of a building that is suspended outside of a support structure and is not supported by the ground. The design and manufacture of cantilever formwork need to take into account the weight and shape of the cantilever structure, as well as the use of formwork supports, to ensure that the formwork can withstand the weight and pressure of the poured concrete.

[0003] Chinese patent CN221031435U discloses a cantilever formwork for construction, including a support mounted on a wall. The support has a load-bearing plate for supporting the cantilever structure. The support also has a folding mechanism for unfolding the load-bearing plate to one side. The folding mechanism includes drive columns rotatably mounted on both sides of the top of the support. The load-bearing plate is hinged to the drive columns. Two drive bars are located on the outer side of the support, and the load-bearing plate is mounted on the drive bars. This design, through the folding mechanism, first unfolds the load-bearing plate inwards, allowing it to rest against the upper part of the wall, reducing the overall load and facilitating the installation of the support on the wall. It also prevents the load-bearing plate from obstructing workers during installation, reducing the difficulty of installing the formwork. Furthermore, during transportation, the drive bars can be rotated to one side for folding, reducing the overall footprint of the device and saving transport space.

[0004] However, in actual use, the transmission bar is the hypotenuse in the triangular support structure of the bracket and the load-bearing plate. The length of the transmission bar is greater than the distance from the hinge point between the transmission bar and the bracket to the hinge point between the bracket and the load-bearing plate. The load-bearing plate can only be rotated to the side of the bracket away from the transmission bar for storage. The fact that the end of the transmission bar extends beyond the bracket will cause the device to occupy more transportation space, which is not conducive to carrying and transporting. Utility Model Content

[0005] The present invention aims to provide a cantilever casting formwork support to solve the problem mentioned above that the prior art is not conducive to carrying and transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cantilevered casting formwork support, installed on the outside of a wall, comprising...

[0007] The bracket is installed on the wall, and a load-bearing plate is rotatably connected to the top of the bracket;

[0008] The folding assembly includes a lower support plate, an upper support plate, a limiting bolt, a limiting plate, and a connecting bolt. One end of the upper support plate is detachably connected to the load-bearing plate, one end of the lower support plate is hinged to the bracket, and the other end of the lower support plate has a sliding groove. The other end of the upper support plate is slidably inserted into the sliding groove. A limiting groove is provided on the upper support plate. The limiting bolt is threaded into the lower support plate, and its end extends into the limiting groove. The connecting bolt passes through the limiting plate and is threaded into the bottom of the bracket. The side of the lower support plate away from the bracket abuts against the limiting plate.

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

[0010] 1. The upper and lower support plates connect the load-bearing plate and the support frame respectively, forming a triangular support structure. The upper support plate can slide within the groove of the lower support plate, and the load-bearing plate can be detached from the upper support plate. When not in use, the overlap size of the upper and lower support plates can be increased, thereby reducing the total length of the upper and lower support plates. This allows the load-bearing plate to rotate along the support frame to the side of the support frame closer to the lower support plate, thus reducing the space occupied by the device when stored and making it easier to carry.

[0011] 2. The bracket and the limiting plate are connected by connecting bolts, so that the limiting plate can provide support for the lower support plate while also being detachable from the bracket. This makes it easier for the limiting plate to make way for the load-bearing plate when folded and stored, further reducing the space required for storage and making the device easy to carry.

[0012] The present invention is further configured such that: the bottom of the load-bearing plate near the wall has a protruding edge, and a relief groove is provided on the protruding edge; the top of the bracket is rotatably installed in the relief groove, and the distance between the top edge of the bracket and the bottom edge of the load-bearing plate is not less than the thickness of the lower support plate.

[0013] The principle and effect of this technical solution: By setting the convex edge and controlling the distance between the top edge of the bracket and the load-bearing plate, the load-bearing plate can rotate to be parallel to the bracket when it rotates around the bracket via the convex edge. At this time, the lower support plate is just between the bracket and the load-bearing plate, so that the device can achieve maximum storage capacity and is easy to transport and carry.

[0014] The present invention is further configured such that: the top of the upper support plate is detachably connected to an installation plate, the bottom of the load-bearing plate is provided with an installation groove, the installation plate abuts against the installation groove, an installation bolt is inserted into the load-bearing plate, the end of the installation bolt is threaded into the installation plate, and the dimension of the installation groove along the length of the load-bearing plate is larger than the dimension of the installation plate along the length of the load-bearing plate.

[0015] The principle and effect of this technical solution: The mounting plate is connected by mounting bolts, so that the mounting plate can be fixed relative to the load plate, thereby ensuring that the upper support plate can stably bear the pressure of the load plate. The mounting plate can be disassembled relative to the load plate, which is convenient for subsequent folding and carrying. By making the size of the mounting groove larger than the mounting plate, the mounting plate can be more easily positioned and installed in the mounting groove.

[0016] The present invention is further configured to include a fixing unit, which includes an outer baffle, a fixing bolt, a plug plate, an inner baffle, and a driving assembly. The side wall of the bracket is provided with a fixing groove, and the wall is provided with a plug hole. The plug plate passes through the plug hole and the fixing groove. The fixing bolt is inserted into the outer baffle and its end extends to be threaded into the plug plate. The outer baffle abuts against the bracket. The inner baffle is slidably fitted onto the plug plate and abuts against the wall. The driving assembly is installed on the plug plate and is used to control the position of the inner baffle relative to the wall.

[0017] The principle and effect of this technical solution: By using the insertion plate to penetrate the fixing slot and the insertion hole, and by using the outer baffle and fixing bolts, the insertion plate can be disassembled and assembled relative to the bracket. The inner baffle abuts against the wall, and the outer baffle abuts against the bracket, thus supporting the bracket and the wall, providing fixation and limiting for the bracket. The insertion plate bears the downward pressure on the bracket, and the abutment between the outer baffle and the bracket bears the deflection force of the bracket, ensuring the stability of the bracket. The drive component can adjust the position of the inner baffle relative to the insertion plate, allowing the inner baffle to abut against walls of different thicknesses by changing its position. Compared to directly fixing the bracket to the wall with bolts, this method is more stable and reliable, easier to assemble and disassemble, and smaller parts such as fixing bolts are less prone to deformation under pressure, allowing for a higher number of reuses.

[0018] The present invention is further configured such that: the driving assembly includes a rotating cap and a screw, a driving groove is provided on the insert plate, the screw is rotatably installed in the driving groove, one end of the screw extends to the outside of the insert plate and is fixed with the rotating cap, the inner baffle is slidably adapted to the driving groove, and the inner baffle is threadedly fitted on the screw.

[0019] The principle and effect of this technical solution: By rotating the cap, the screw can be driven to rotate, which can drive the inner baffle to slide along the insert plate, so that the insert plate can be tightly pressed against the wall. Then, the clamping force between the inner baffle and the outer baffle will firmly install the bracket on the wall without the need for multiple drilling.

[0020] The present invention is further configured such that: multiple fixing grooves are spaced apart along the length of the bracket.

[0021] The principle and effect of this technical solution: The setting of multiple fixing slots allows the position of the bracket to be adjusted according to the actual height of the wall and the height required for pouring the formwork, avoiding the problem of multiple drilling due to positioning errors when using bolts to connect to the wall.

[0022] The present invention is further configured such that the angle between the contact surface of the limiting plate and the lower support plate and the horizontal plane is 45°.

[0023] The principle and effect of this technical solution: By limiting the contact angle between the limiting plate and the lower support plate, the rotation angle of the lower support plate relative to the bracket is limited. With the 45° support setting, half of the force of the load-bearing plate away from the wall and the support end against the upper and lower support plates is converted into a vertical downward pressure and half into a pressure force perpendicular to the wall. This makes the stress direction of the bracket more dispersed and less likely to concentrate, thus protecting the local stress of the bracket. Attached Figure Description

[0036] Example:

[0037] As attached Figure 1-4 As shown, this utility model discloses a cantilever casting formwork support, including a support 201, a folding assembly, a load-bearing plate 301, and a fixing unit. The bottom of the load-bearing plate 301 near the wall has a protruding edge 304, so that the load-bearing plate 301 and the protruding edge 304 together form the shape of a "7". The side wall of the protruding edge 304 has two symmetrical relief grooves 302. A support 201 is rotatably installed in each of the two relief grooves 302. The distance between the top edge of the support 201 and the bottom edge of the load-bearing plate 301 is not less than the thickness of the lower support plate 401. When installing this device, the load-bearing plate 301 can be rotated to the top of the wall 101 first (at this time, the protruding edge 304 and the load-bearing plate 301 abut against the top of the wall 101, and the load-bearing plate 301 is in a vertical state, not shown in the figure), thereby overcoming the resistance brought by the weight of the load-bearing plate 301 to the installation of the support 201.

[0038] Each bracket 201 corresponds to a set of folding components and a fixing unit. The folding components include a lower support plate 401, an upper support plate 403, a limiting bolt 405, a limiting plate 406, and a connecting bolt 407. The top of the upper support plate 403 is detachably connected to a mounting plate 501 (which can be as follows). Figure 1 The bolt connection shown, or any other stable connection and fixation method, will be used (only briefly described again). A mounting groove 303 is provided at the bottom of the load-bearing plate 301. The mounting plate 501 abuts against the mounting groove 303. A mounting bolt 502 is inserted into the load-bearing plate 301, and the end of the mounting bolt 502 is threaded into the mounting plate 501. The dimension of the mounting groove 303 along the length of the load-bearing plate 301 is larger than the dimension of the mounting plate 501 along the length of the load-bearing plate 301. One end of the lower support plate 401 is hinged to the bracket 201, and the other end of the lower support plate 401 has a sliding groove 40. 2. The other end of the upper support plate 403 is slidably inserted into the slide groove 402. Two limiting grooves 404 are provided on the upper support plate 403, one for unfolded connection positioning and the other for folded connection positioning. A limiting bolt 405 is threaded into the lower support plate 401, with its end extending into the limiting groove 404. A limiting plate 406 is installed at the bottom of the bracket 201 via connecting bolts 407, and the side of the lower support plate 401 away from the bracket 201 abuts against the limiting plate 406. The angle between the contact surface of the limiting plate 406 and the lower support plate 401 and the horizontal plane is 45°. The specific shape of the limiting plate 406 is as follows: Figure 1 As shown.

[0039] The fixing unit includes an outer baffle 603, fixing bolts 604, a plug plate 601, an inner baffle 605, and a drive assembly. The side wall of the bracket 201 is provided with multiple fixing slots 202 spaced apart. The wall 101 has insertion holes 102, the positions of which are determined according to actual construction. After pouring, concrete or similar materials can be poured into the insertion holes 102 to fill them. The plug plate 601 passes through the insertion holes 102 and the fixing slots 202. The fixing bolts 604 are inserted into the outer baffle 603, with their ends extending to the insertion holes. The plate 601 is threaded in, the outer baffle 603 abuts against the bracket 201, and the inner baffle 605 is slidably fitted on the plate 601 and abuts against the wall 101. The drive assembly includes a rotating cap 606 and a screw 607. The plate 601 has a drive groove 602, and the screw 607 is rotatably installed in the drive groove 602. One end of the screw 607 extends to the outside of the plate 601 and is fixed to the rotating cap 606. The inner baffle 605 is slidably adapted to the drive groove 602, and the inner baffle 605 is threadedly fitted on the screw 607.

[0040] When the fixing unit is in use, the insert plate 601 can be pre-embedded in the wall structure 101 to form the insertion hole 102. After use, the insert plate 601 can be knocked out from the wall. When used in self-built brick and tile houses, this fixing unit will not damage the brick structure, thus protecting the exterior wall. Compared with the traditional bolt fixing method, which requires multiple bolts and makes it easy for the bolts to drill into the bricks and damage the brick structure, resulting in a decrease in wall strength, this device can avoid damage to the wall structure by removing the insert plate 601 and filling it with concrete and bricks after use. Therefore, using this fixing unit can reduce damage to the exterior wall.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
