[0001] The utility model relates to the technical field of building construction, in particular to a gap plugging structure and a shear wall formwork system. Background Technique
[0002] High-rise and super high-rise buildings are mainly of frame-shear wall and shear wall structures. During the construction of cast-in-place reinforced concrete walls and columns, due to the inability to accurately control the height difference between the cast-in-place panels, it is necessary to reduce the height when preparing the shear wall formwork to control the installation of the matching floor slabs. Therefore, a gap will appear between the lower end face of the shear wall formwork and the floor slab, so it is necessary to plug this gap.
[0003] In the existing gap plugging structure, a dense wire mesh is plugged at the gap by concrete steel nails and cement mortar is injected on the outer layer to achieve the plugging effect. However, due to the holes in the wire mesh itself and insufficient anchoring force, the plugging effect is limited, and the use of mortar will cause honeycombing and pitting on the bottom of the concrete shear wall, affecting the appearance. Content of the Utility Model

[0017] Preferably, at the joint between the shear wall formwork and the floor, a leak-proof groove with an opening facing away from the pouring cavity is formed, and the plugging member is clamped in the leak-proof groove and presses against the bottom of the leak-proof groove.

[0035] The following further illustrates the technical solution of the present utility model in conjunction with the accompanying drawings and through specific embodiments.
[0036] like Figure 1 - Figure 2 As shown, the utility model provides a gap plugging structure for plugging gaps. The gap plugging structure includes a plugging member 1, a reinforcement member 2 and a locking member 3. The plugging member 1 is configured to plug the joint 300 between the shear wall formwork 100 and the floor slab 200; a bending portion 21 is provided at one end of the reinforcement member 2 in the length direction, and the other end abuts against the back rib 101 of the shear wall formwork 100, and the bending portion 21 is configured to press the plugging member 1 against the joint 300; the locking member 3 is configured to connect and lock the reinforcement member 2 in series to the shear wall formwork 100.
[0037] One end of the reinforcement member 2 is pressed against the back rib 101 of the shear wall formwork 100, and the bent portion 21 at the other end can press the sealing member 1 against the joint 300 between the shear wall formwork 100 and the floor slab 200. The locking member 3 connects the reinforcement member 2 in series and locks it on the shear wall formwork 100. The setting of the reinforcement member 2 is more conducive to transmitting the pressure to the sealing member 1. There is no need to use cement mortar to seal the gap, and no honeycombed surface will be produced. The structure is simple, the production cost is low, and local materials can be used at the construction site.
[0038] Specifically, the locking member 3 includes a through-rod 31 and two locking members 32. The through-rod 31 is configured to connect the reinforcement member 2 and the shear wall formwork 100 in series; the two locking members 32 are screwed to the two ends of the through-rod 31 in the length direction, and the locking members 32 can lock the through-rod 31 in the length direction of the through-rod 31. With the above arrangement, the locking members 32 and the through-rod 31 cooperate to provide pressure for the reinforcement member 2 and the blocking member 1.
[0039] Specifically, the locking member 3 further includes two locking blocks 33, which are respectively sleeved at the two ends of the length direction of the through-connecting rod 31, and the locking member 32 presses the locking blocks 33 against the side of the reinforcing member 2 away from the shear wall formwork 100 in a one-to-one correspondence. The arrangement of the locking blocks 33 can increase the force-bearing area of the reinforcing member 2 and improve the structural stability.
[0040] Specifically, a receiving groove 321 is provided on one side of the locking block 33 facing the locking member 32, and the connecting rod 31 is inserted into the receiving groove 321 from the bottom of the groove 321, and both ends of the connecting rod 31 in the length direction do not extend out of the receiving groove 321. The provision of the receiving groove 321 can prevent the end of the connecting rod 31 from scratching workers, thereby improving the safety of the structure.
[0041] Specifically, the plugging member 1 is made of wood. The above configuration enables the plugging member 1 to have a certain elasticity and to be able to absorb water and expand to a certain extent, and the production cost is low, and the material can be obtained locally at the construction site.
[0042] The present utility model further provides a shear wall formwork system for the casting construction of shear walls. The shear wall formwork system includes two relatively arranged shear wall formworks 100 and the above-mentioned gap sealing structure. The two shear wall formworks 100 and the floor slab 200 enclose a casting cavity, and the shear wall is cast and formed in the casting cavity.
[0043] It can be understood that the shear wall formwork system has all the beneficial effects of the gap sealing structure, which will not be elaborated here.
[0044] Specifically, at the joint 300 between the shear wall formwork 100 and the floor slab 200, a leakage prevention groove with an opening facing away from the casting cavity is provided. The sealing member 1 is clamped in the leakage prevention groove and presses against the bottom of the leakage prevention groove. The setting of the above-mentioned leakage prevention groove can increase the contact area between the shear wall formwork 100 and the sealing member 1, improve the anchoring force of the sealing member 1, have a better sealing effect, and prevent the sealing member 1 from tilting in the vertical plane.
[0045] Specifically, in the extending direction of the shear wall, the shear wall formwork 100 is provided with multiple groups that can be spliced with each other. Both the backing ribs 101 and the sealing member 1 extend along the extending direction of the shear wall. The reinforcing members 2 are arranged at intervals along the extending direction of the shear wall, and the locking members 3 correspond to the reinforcing members 2 one by one. With the above setting, the number of the locking members 3 and the reinforcing members 2 can be adaptively set according to the actual requirements of the construction site, and the versatility is strong.
[0046] Specifically, the shear wall formwork 100 is provided with a bent-up portion 102. In the extending direction of the shear wall, the bent-up portions 102 of adjacent shear wall formworks 100 can abut and fit against each other. The setting of the above-mentioned bent-up portion 102 increases the contact area between two adjacent shear wall formworks 100 and facilitates their mutual connection.
[0047] More specifically, connection holes are provided on the bent-up portion 102, and the connection holes of two adjacent bent-up portions 102 can communicate with each other. With the above setting, the mutual connection of two adjacent shear wall formworks 100 can be realized by using commonly used pin, rivet or bolt structures in the art.
