Description

Technical Field

[0001] The utility model relates to a template supporting structure for a joint between shear wall layers. Background Art

[0002] In building construction, ensuring that the joints of reinforced concrete shear walls do not leak is an important node that is complex and difficult to construct, especially when there are many joints between the exterior walls of high-rise structures, which makes construction even more difficult. Water seepage occurs at the construction joints of some exterior walls, seriously affecting the use function and visual quality. Summary of the invention

[0003] The utility model aims to provide a template support structure for the joint between shear wall layers, adds a leak-proof rubber pad at the bottom end of the outer template, and adds template support points on the lower outer wall, which effectively solves the problem of slurry leakage at the joint of the outer wall construction joint.

[0004] In order to achieve the above purpose, the technical solution of the utility model is:

[0005] A template support structure for the joint between shear walls, including an inner template and an outer template clamped and fixed by an inner steel pipe and an outer steel pipe on both sides of the upper shear wall to be poured, a shear support rod extending from the poured lower shear wall, the shear support rod being provided with a clamping block, the outer template and the outer steel pipe being supported on the shear support rod, the outer template being horizontally provided with a groove on the surface attached to the lower shear wall, a long rubber sealing pad being provided in the groove, the shear support rod pressing the outer template and the lower shear wall through the clamping block so that the rubber sealing pad is compressed and tightly adhered to the lower shear wall to form a seal.

[0006] The solution is further as follows: positioning nuts are pre-embedded in the poured lower shear wall, the shear support rod is a bolt rod with threads on both ends, one end of the bolt rod is screwed into the positioning nut to fix it to form a shear support rod extending from the lower shear wall, the clamping block is a sleeve with a protrusion at one end to form a step, the sleeve is sleeved into the bolt rod, the protrusion of the sleeve is against the outer steel pipe, the outer steel pipe presses the outer formwork, and the other end of the bolt rod on the outer side of the sleeve step is screwed into the locking nut, and as the locking nut is screwed in, the outer formwork and the lower shear wall are pressed tightly so that the rubber sealing pad is compressed and tightly adheres to the lower shear wall to form a seal.

[0007] A further solution is: the shear support rod passes through the outer template and the outer steel pipe to support the outer template and the outer steel pipe.

[0008] A further solution is that the upper end surface of the rubber sealing pad is flush with the upper end surface of the lower shear wall.

[0009] The beneficial effects of the utility model are:

[0010] 1. Compared with the existing technology, it has a simple structure, easy operation, saves labor and materials, and solves the safety hazards in the template installation process to a certain extent.

[0011] 2. Compared with the existing technology, the bottom of the formwork is reinforced by pre-embedded locking screws at the joints to improve the stability of the main structure. The added rubber pads solve the problem of leakage at the joints of the traditional shear wall to be poured.

[0012] 3. Compared with the existing technology, the support ensures the quality of concrete construction at the joints of the shear wall, is easy to operate, improves the construction speed, and saves construction time.

[0013] 4. Compared with the existing technology, this support only requires one-time investment in materials and can be recycled multiple times, which meets the national environmental protection requirements of green construction. At the same time, the application of this support avoids material waste.

[0017] A template support structure for the joint between shear walls, such as Figure 1 and Figure 2 As shown, the formwork support at the joint between the shear wall layers includes an inner formwork 4 and an outer formwork 5 which are clamped and fixed by an inner steel pipe 2 and an outer steel pipe 3 on both sides of the upper shear wall 1 to be poured, a shear support rod 7 is extended from the poured lower shear wall 6, and the shear support rod is provided with a clamping block 8, the outer formwork 5 and the outer steel pipe 3 are supported on the shear support rod 7, and the outer formwork 5 is horizontally provided with a long groove 501 on the surface attached to the lower shear wall, and a long sponge rubber sealing pad 9 with a width of 2 cm is provided in the groove 501, and the shear support rod 7 presses the outer formwork 5 and the lower shear wall 6 through the clamping block 8 so that the rubber sealing pad 9 is compressed and tightly adheres to the lower shear wall 6 to form a seal.

[0018] In the embodiment: a positioning nut 10 is pre-embedded in the poured lower shear wall 6. Figure 2As shown, the shear support rod 7 is a bolt rod with threads on both ends, one end of the bolt rod is screwed into the positioning nut 10 to fix it to form a shear support rod extending from the lower shear wall 6, the clamping block 8 is a sleeve with a protrusion at one end to form a step 801, the sleeve is sleeved into the bolt rod, the protrusion 801 of the sleeve is against the outer steel pipe 3, the outer steel pipe 3 presses the outer formwork 5, and the other end of the bolt rod on the outer side of the sleeve step is screwed into the locking nut 11, and a gasket 12 is placed in front of the locking nut 11. As the locking nut 11 is screwed in, the outer formwork 5 is pressed against the lower shear wall 6 so that the rubber sealing pad 9 is compressed and tightly adheres to the lower shear wall 6 to form a seal.

[0019] In order to support stability: the shear support rod 7 is inserted from the outer formwork 5 and the outer steel pipe 3 and passes through to support the outer formwork 5 and the outer steel pipe 3.

[0020] Wherein: the upper end surface of the rubber sealing pad is flush with the upper end surface of the lower shear wall.
