DETAILED DESCRIPTION

[0058] The following will be combined with the accompanying Figures 1-12 Further detailed description will be made to the present application.

[0059] The embodiment of the application discloses a formwork support assembly for building construction, which is used for quickly supporting a completed formwork structure and improving the efficiency of pouring construction.

[0060] Referring to Figure 1 A formwork support assembly for building construction comprises two movable frames 1, and universal wheels 16 are installed at the bottom of the movable frames 1 to facilitate the movement of the movable frames 1. A containing groove 11 is formed in the side of the movable frame 1 close to the adjacent movable frame 1, so that the movable frames 1 are arranged in a C shape as a whole. When the two movable frames 1 abut against each other, the two containing grooves 11 can jointly form a containing area, and the shape of the containing area is the same as that of the built formwork structure, so that the two movable frames 1 can be stably positioned outside the formwork structure and the possibility of deviation of the movable frames 1 is reduced.

[0061] In addition, the two movable frames 1 are detachably fixed through a locking component 12. The locking component 12 comprises a sub-dog part fixed to one of the movable frames 1 and a female dog part fixed to the other movable frame 1. When the two movable frames 1 abut against each other, the sub-dog part can be buckled with the female dog part. The sub-dog part and the female dog part are both prior art, and will not be described here.

[0062] Referring to Figure 2 The formwork structure of the embodiment is arranged in a rectangular shape, and a plurality of limiting parts 41 are integrally formed on each side of the formwork structure. Referring to Figure 1 The movable frame 1 is provided with a plurality of groups of support units 2, and the number of the support units 2 is equal to that of the limiting parts 41. Each group of support units 2 located on the side of the formwork structure can be limited with each limiting part 41 of the adjacent side, so as to support the formwork structure and reduce the possibility of formwork explosion.

[0063] Referring to Figure 3 、 Figure 4 The support unit 2 comprises an inclined support column 21, a reinforcing column 22, a pressure bearing seat 23, a driving component 24 and a guide telescopic mechanism 25. One end of the inclined support column 21 is rotatably connected with a sliding seat 211, and the movable frame 1 is provided with a movable groove 17 on the top surface. The sliding seat 211 is slidingly installed in the movable groove 17, so that the inclined support column 21 can slide and rotate relative to the movable frame 1. The pressure bearing seat 23 is rotatably connected to the end of the inclined support column 21 away from the sliding seat 211. The side of the pressure bearing seat 23 away from the inclined support column 21 is provided with a limiting groove 231 extending through the two opposite sides of the pressure bearing seat 23, so that the pressure bearing seat 23 is arranged in a C shape as a whole. When the two movable frames 1 are connected outside the prefabricated base 3, each limiting part 41 enters each limiting groove 231.

[0064] The guide telescopic mechanism 25 comprises a first movable column 251 and a second movable column 252. The first movable column 251 is fixed to the bottom of the pressure bearing seat 23 and is arranged obliquely relative to the vertical direction. The second movable column 252 is fixed to the top surface of the moving frame 1 and is arranged obliquely relative to the vertical direction. The first movable column 251 and the second movable column 252 are movably inserted and connected with each other. The first movable column 251 can be inserted into the end of the second movable column 252, or the second movable column 252 can be inserted into the end of the first movable column 251. The extension directions of the two columns remain unchanged. By making one side of the limiting groove 231 of the pressure bearing seat 23 always face the formwork structure, the pressure bearing seat 23 can only move along the telescopic direction of the guide telescopic mechanism 25.

[0065] The driving component 24 of the embodiment is a hydraulic cylinder. The driving component 24 is fixed to the top surface of the moving frame 1 and located outside the sliding seat 211. The movable end of the driving component 24 is connected to the sliding seat 211. By controlling the action of the driving component 24, the sliding seat 211 can be moved, the inclined support column 21 can rotate around the hinge position between itself and the sliding seat 211, the pressure bearing seat 23 can be forced to move along the telescopic direction of the guide telescopic mechanism 25 and move towards the formwork structure, and finally the pressure bearing seat 23 can be tightly attached to the side surface of the formwork structure, and the lower end wall of the limiting groove 231 can be tightly attached to the limiting piece 41, thereby stably supporting the formwork structure.

[0066] One end of the reinforcing column 22 is rotationally connected to the top of the moving frame 1, and the rotationally connected position of the reinforcing column 22 and the moving frame 1 is located between the sliding seat 211 and the second movable column 252. The end of the reinforcing column 22 away from the moving frame 1 is rotationally connected with a sliding block 221. The side surface of the inclined support column 21 is fixed with a sliding rail 212, and the sliding block 221 is slidingly connected to the sliding rail 212. Through the cooperation of the sliding block 221 and the sliding rail 212, the reinforcing column 22 is slidingly connected to the middle part of the inclined support column 21, which can enhance the support strength and stability of the inclined support column 21 and reduce the possibility of local bending deformation or even fracture of the inclined support column 21 under stress.

[0067] The implementation principle of the formwork support assembly for building construction according to the embodiment is as follows:

The two moving frames 1 that abut against each other are fixed and connected through the lock buckle component 12, so that the moving frames 1 are stably positioned. At this time, each limiting piece 41 on the outside of the formwork structure is located in the limiting groove 231 of each pressure bearing seat 23.

[0069] By controlling the driving parts 24 of each group of support units 2 to act, the corresponding sliding seat 211 is driven to move, which can make the inclined support column 21 connected with the sliding seat 211 rotate, and force the pressure seat 23 to move along the telescopic direction of the telescopic guide mechanism 25, and move to the direction close to the formwork main body 4. Finally, the pressure seat 23 is attached to the side of the formwork structure, and the lower end wall of the limiting groove 231 is attached to the limiting piece 41, which can play a good supporting role on the formwork structure and reduce the possibility of mold explosion. The whole supporting operation is fast and convenient, which saves the time of setting a large number of inclined support rods, and highlights the convenient construction advantages of the whole formwork system, so as to quickly complete the construction and pouring of the load-bearing column.
