[0002] The pouring of concrete walls of high-rise buildings is a complex and delicate process involving multiple steps and key links.

[0003] In the traditional wall casting mode, first of all, the formwork needs to be made according to the construction drawings and project requirements, and then the formwork is transported to the construction site and supported. After that, the steel bars are tied inside the supported formwork, and then the prepared concrete is poured into the supported formwork. After waiting for the concrete to solidify, the formwork can be disassembled and removed.

[0004] However, in the traditional wall casting mode, the connection between the templates is fixed by a large number of bolts, nuts, etc., which is a cumbersome process and takes a lot of time.

[0024] The following is combined with Figure 1-5 This application is described in further detail.

[0025] The embodiment of the present application discloses a tool-type formwork structure for a concrete wall of a high-rise building.

[0026] See also Figure 1 The tool-type template structure includes a template block 1, and the template block 1 includes an inner plate 2 and an outer plate 3. The inner plates 2 have two groups, namely a first inner plate 21 and a second inner plate 22.

There are two first outer plates 31 and they are symmetrically arranged, and there are two second outer plates 32 and they are symmetrically arranged. The first outer plates 31 and the second outer plates 32 are staggered in the circumferential direction, and the second outer plates 32 are located between the first outer plates 31 and abut against each other. The first outer plates 31 and the second outer plates 32 are arranged around the inner plate 2, and a casting cavity 11 is formed between the inner plate 2 and the outer plates 3 for pouring concrete. In order to improve the strength of the wall formed by casting, a steel cage is tied in the casting cavity 11, and the steel cage is tied and fixed to the reserved steel bars on the ground.

When in use, the outer plate 3 and the inner plate 2 are connected by the connecting columns 12, which is conducive to resisting the static pressure exerted on the outer plate 3 and the inner plate 2 by the concrete in the pouring space.

[0029] There are multiple inner plates 2 stacked up and down in the vertical direction, that is, there are multiple first inner plates 21 and multiple second inner plates 22 stacked up and down in the vertical direction, respectively. There are multiple outer plates 3 stacked up and down in the vertical direction, that is, there are multiple first inner plates 21 and multiple second inner plates 22 stacked up and down in the vertical direction, respectively. The tool-type formwork structure also includes a fixed column 13 and a locking column 14. The fixed column 13 is arranged in the casting cavity 11. There are multiple fixed columns 13 and they are evenly spaced along the extension direction of the casting cavity 11. The two ends of the fixed column 13 are respectively abutted against the opposite sides of the inner plate 2 and the outer plate 3. The fixed column 13 is tied and fixed to the steel cage in the casting cavity 11. In the embodiment of the present application, there are four fixed columns 13.

[0030] See also Figure 1 and Figure 2 , locking holes 15 are respectively opened in the middle of the inner plate 2 and the outer plate 3, and the locking holes 15 are respectively aligned with the ends of the fixing columns 13, the central axis of the locking hole 15 coincides with the central axis of the fixing column 13, and the diameter of the locking hole 15 is smaller than the diameter of the fixing column 13. The locking column 14 is passed through the locking hole 15, and there is a one-to-one correspondence between the locking column 14 and the locking hole 15. The locking column 14 is threadedly connected to the end of the fixing column 13, and a locking block 141 is fixedly connected to one end of the locking column 14 away from the fixing column 13. During installation, the locking block 141 abuts against the outer walls of the inner plate 2 and the outer plate 3. At this time, the fixed connection between the inner plate 2 and the outer plate 3 is realized by the locking column 14 and the fixing column 13, and the spacing between the inner plate 2 and the outer plate 3 is maintained by the fixing column 13.

[0031] See also Figure 2 and Figure 3 , sealing grooves 16 are formed at opposite ends of the inner plate 2 and at opposite ends of the outer plate 3, and the sealing grooves 16 extend in the vertical direction. Extrusion grooves are formed in the inner plate 2 and the outer plate 3, respectively. The extrusion grooves are located directly above the locking holes 15, and the extrusion grooves correspond to the locking holes 15 one by one. The inner plate 2 and the outer plate 3 are respectively provided with extrusion airbags 4, which are installed in the extrusion grooves and correspond one by one. The outer walls and the middle positions of the extrusion airbags 4 are fixedly connected to the walls of the extrusion grooves. The inner plate 2 and the outer plate 3 are symmetrically formed with connecting holes, and the two sides of the connecting holes are respectively connected to the sealing grooves 16 and the extrusion grooves. The two opposite sides of the extrusion airbags 4 are respectively fixedly connected with sealing airbags 5, and the sealing airbags 5 are accommodated in the connecting holes.

[0032] See also Figure 4 and Figure 5 The tool-type template structure also includes an extrusion assembly 6. When the locking column 14 passes through the locking hole 15, the extrusion assembly 6 squeezes the extrusion airbag 4, and the air in the extrusion airbag 4 flows into the sealing airbag 5, so that the sealing airbag 5 expands into the sealing groove 16 (the sealing groove 16 is Figure 3 At this time, the outer wall of the sealing airbag 5 on the second outer plate 32 abuts against the adjacent first outer plate 31, and the outer wall of the sealing airbag 5 on the second inner plate 22 abuts against the adjacent first inner plate 21. In addition, the sealing airbag 5 fills the sealing groove 16, which is conducive to achieving the sealing between the adjacent inner plates 2 and the adjacent outer plates 3, and reducing the amount of concrete leakage in the casting cavity 11.

[0033] The extrusion assembly 6 includes an extrusion plate 61, an extrusion column 62, a slider 63 and a push plate 64. The extrusion plate 61 is fixedly connected to the bottom of the extrusion airbag 4 and slides up and down in the extrusion groove. A receiving groove 151 is provided on the top hole wall of the locking hole 15. The receiving groove 151 is located between the locking hole 15 and the extrusion groove. The inner plate 2 and the outer plate 3 are rotatably connected to the hinge shaft 18 respectively. The hinge shaft 18 is located in the receiving groove 151 and away from the casting cavity 11. The push plate 64 is a long plate-like structure. The push plate 64 is fixedly connected to the outer peripheral side of the hinge shaft 18, and the push plate 64 is located in the receiving groove 151.

[0034] The inner plate 2 and the outer plate 3 are respectively provided with elastic driving members, which are driving torsion springs 181, which are sleeved on the outer peripheral side of the hinge shaft 18, and one end of the driving torsion spring 181 abuts against the side of the push plate 64 facing away from the locking hole 15, and the other end abuts against the wall of the receiving groove 151. When the driving torsion spring 181 is elastically released, the driving push plate 64 is flipped downward until the push plate 64 is flipped into the locking hole 15 near the casting cavity 11 and abuts against the bottom hole wall of the locking hole 15. When the locking column 14 passes through the locking hole 15, the locking column 14 slides on the pushing plate 64, and at this time, the locking column 14 pushes the pushing plate 64 to flip into the receiving groove 151.

[0035] The slider 63 is arranged on the side wall of the push plate 64 away from the locking hole 15, and the slider 63 slides on the push plate 64 and slides along the length direction. The extrusion column 62 slides up and down in the inner plate 2 and the outer plate 3, and the extrusion column 62 corresponds to the extrusion plate 61 one by one. One end of the extrusion column 62 is fixedly connected to the bottom of the extrusion plate 61, and the other end is ball-hinged to the side of the slider 63 close to the extrusion plate 61. When the push plate 64 flips upward into the accommodating groove 151, the extrusion column 62 is pushed to slide upward, driving the extrusion plate 61 to squeeze the extrusion airbag 4 upward, so that the airflow in the extrusion airbag 4 flows into the sealing airbag 5. While the extrusion column 62 slides upward, the slider 63 slides on the push plate 64 along the length direction.

[0036] See also Figure 3 and Figure 5 The extrusion airbag 4 is provided with two mounting blocks 41, and the two mounting blocks 41 are respectively fixedly connected to the inner walls on opposite sides of the extrusion airbag 4. A rotating shaft 42 is rotatably connected between the two opposite mounting blocks 41, and a supporting block 51 is fixedly connected to the inner wall of the sealing airbag 5 on the side away from the extrusion airbag 4. A connecting rope 43 is fixedly connected to the supporting block 51, and one end of the connecting rope 43 away from the supporting block 51 is fixedly connected to the outer peripheral side of the rotating shaft 42.

[0037] A driving coil spring 44 is wound around the outer peripheral side of the rotating shaft 42, one end of the driving coil spring 44 is clamped and fixed on the outer peripheral side wall of the rotating shaft 42, and the other end is clamped and fixed on the mounting block 41. When the driving coil spring 44 is elastically released, the rotating shaft 42 rotates and winds the winding connecting rope 43, so that the connecting rope 43 pulls the supporting block 51, driving the sealing airbag 5 to shrink back into the connecting hole. When the sealing airbag 5 expands into the sealing groove 16, the supporting block 51 pulls the connecting rope 43, so that the rotating shaft 42 releases the connecting rope 43, and at this time the driving coil spring 44 enters an elastic contraction state.

[0038] The bottom of the inner plate 2 and the outer plate 3 are respectively formed with a fixing groove 19, and the top of the inner plate 2 and the outer plate 3 are respectively formed with a connecting groove 192, which is connected to the extrusion groove; and when the inner plate 2 is stacked up and the outer plate 3 is stacked up, the upper and lower adjacent fixing grooves 19 and connecting grooves 192 are aligned and connected with each other. A fixing block 45 is fixedly connected to the top of the extrusion airbag 4, and a guide surface 451 is formed on the top of the fixing block 45 in an inclined and symmetrical manner, and the guide surface 451 guides the fixing block 45 to be inserted into the fixing groove 19.

[0039] In the initial state, the fixed block 45 is located in the extrusion groove. When the extrusion plate 61 squeezes the extrusion airbag 4 upward, the extrusion airbag 4 expands upward, driving the fixed block 45 to pass through the connecting groove 192 and enter the fixed groove 19. At this time, the top part of the fixed block 45 is inserted into the fixed groove 19, which is beneficial to improve the shear resistance between the upper and lower inner plates 2 and the shear resistance between the upper and lower outer plates 3.

[0040] The inner plate 2 and the outer plate 3 are respectively hinged with a fixing plate 17 at the top. Two fixing plates 17 are symmetrically arranged and located directly above the fixing block 45. The hinge points of the two fixing plates 17 are located at positions far away from each other. The fixing groove 19 has installation grooves 191 respectively opened on the vertical side walls on both sides. When the fixing block 45 is inserted into the fixing groove 19, the fixing block 45 slides on the side wall of the fixing plate 17 away from the fixing groove 19, pushing the fixing plate 17 to flip upward until it abuts against the groove wall of the installation groove 191 away from the fixing groove 19. At this time, the fixing block 45 abuts against the opposite sides of the two fixing plates 17, further improving the shear resistance between the inner plates 2 and the shear resistance between the outer plates 3. A clamping groove 193 is provided on the vertical groove wall of the installation groove 191 away from the fixing groove 19, and a clamping block 171 is fixedly connected to the fixing plate 17. The clamping block 171 is a right-angled triangle block structure, and the inclined surface of the clamping block 171 faces away from the push plate 64, and one of the right-angled surfaces of the clamping block 171 is located near the hinge point of the fixing plate 17. When the fixing plate 17 abuts against the groove wall on the side away from the fixing groove 19, the clamping block 171 is clamped into the clamping groove 193, and the bottom of the clamping block 171 abuts against the groove wall at the bottom of the clamping groove 193, which is conducive to limiting the upper and lower inner plates 2 from moving away from each other and limiting the upper and lower outer plates 3 from moving away from each other.

[0041] The implementation principle of a tool-type formwork structure for a high-rise building concrete wall in the embodiment of the present application is as follows: Before pouring the concrete wall of a high-rise building, the outer plate 3 is supported, and then the steel cage is tied, and when the steel cage is tied, the fixed column 13 is tied and fixed with the steel cage at the same time. Then the inner plate 2 is supported, and the number of the outer plate 3 and the inner plate 2 is determined according to the height of the wall. Then the locking column 14 is inserted and fixed. When the locking column 14 is inserted and fixed, the fixed block 45 is inserted into the fixed groove 19, the fixed plate 17 is turned into the installation groove 191, and the clamping block 171 is clamped into the clamping groove 193, and the airflow in the extrusion airbag 4 flows into the sealing airbag 5, so that the sealing airbag 5 expands into the sealing groove 16, and the first inner plate 2 and the second inner plate 2 are sealed, and the first outer plate 31 and the second outer plate 32 are sealed. Finally, the connecting column 12 is fixed and supported, and then the concrete can be poured into the pouring cavity 11 to realize the pouring of the wall, which can make the template structure adapt to the wall height and greatly shorten the support time of the template structure.

[0042] When the concrete solidifies, the formwork structure can be disassembled. At this time, the connecting column 12 is first removed, and then the locking column 14 is removed. Then, the formwork blocks 1 can be pried away from the wall one by one in the horizontal direction, which greatly shortens the disassembly time of the formwork structure.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
