Description

Technical Field

[0001] This utility model relates to the field of building support technology, and in particular to a one-time molding support frame for an ultra-long waterproof post-pouring strip. Background Technology

[0002] A post-cast strip is a concrete strip left at the corresponding position of the foundation slab, wall, or beam in the construction process to prevent harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or settlement. According to the design or construction specifications, the post-cast strip temporarily divides the structure into several parts. After the internal shrinkage of the component, the construction joint concrete is poured again after a certain period of time to connect the structure into a whole.

[0003] Traditional formwork construction for post-cast strips in floor slabs involves using the same formwork support system for both the beam / slab and the post-cast strip. Since the floor slab and the post-cast strip cannot be poured simultaneously, the support frame for the post-cast strip must be removed along with the floor slab support frame before a second formwork is constructed at the post-cast strip. This process can easily result in poor contact between the formwork and the concrete surface, causing concrete slurry to squeeze out along the gaps. This results in a height difference at the junction of the new and old concrete, causing the bottom of the floor slab to be uneven.

[0004] Therefore, it is necessary to provide a new one-time molding support frame for ultra-long waterproof post-pouring strips to solve the above-mentioned technical problems. Utility Model Content

Installed on the edge of the post-pouring strip 8, the positioning structure 4 includes a positioning plate 41, a telescopic rod 42, a positioning rod 43, and a spring 44. The positioning plate 41 is engaged with the edge of the post-pouring strip 8. The telescopic rod 42 is vertically fixed to one end of the surface of the positioning plate 41, and the positioning rod 43 is vertically fixed to the other end of the surface of the positioning plate 41. The spring 44 is disposed inside the telescopic rod 42. A connecting structure 3 is connected between the positioning rod 43 and the fixed platform 1. A reinforcing structure 5 is vertically supported between the upper and lower floor slabs. The reinforcing structure 5 includes a vertical pole 51, a horizontal bar 52, and a connector 53.

The horizontal bar 52 is connected between the support rod 21 and the vertical pole 51 through the connector 53.

[0023] In the specific implementation process, such as Figure 1As shown, the screw tube 24 abuts against the bottom end of the branch support frame 22, and the branch support frame 22 is supported on the bottom surfaces of both ends of the timber 7 by the positioning block 23; the side wall of the support rod 21 is also provided with the insertion plate 53, and the crossbar 52 and the insertion plate 53 are fixed by a pin, which makes it easy to restrict the position of the branch support frame 22 by the screw tube 24, so that the top end of the branch support frame 22 and the top end of the support rod 21 are at the same horizontal height, thereby providing stable support for the timber 7.

[0024] In the specific implementation process, such as Figure 1 As shown, the positioning plate 41 is L-shaped, and the positioning plate 41 is engaged with the edge of the lower floor slab surface by the inner corner, so that the positioning plate 41 can be restricted in position by the included angle at the post-pouring strip 8 of the floor slab.

[0025] In the specific implementation process, such as Figure 1 As shown, the connecting structure 3 includes a connecting rod 31, a first connecting member 32, and a second connecting member 33.

Furthermore, the connecting rod 31 and the telescopic rod 42 are connected via the first connecting member 32, which allows the telescopic rod 42 to restrict and support the position of the connecting rod 31, and also restricts the position of the positioning plate 41.

[0026] The working principle of the one-time molding support frame for the ultra-long waterproof post-pouring strip provided by this utility model is as follows:

[0027] In use, firstly, the positioning plate 41 is engaged with the inner corner of the floor slab at the edge of the lower post-pouring strip 8, with one end of the positioning rod 43 facing outwards. The connecting rod 31 is then connected to the top of the positioning rod 43, and the other end of the connecting rod 31 is engaged with the side wall of the fixed platform 1 via the second connecting piece 33 and secured with a pin. The fixed platform 1 is supported directly above the post-pouring strip 8 by the connecting rod 31 and the positioning rod 43. Then, the connecting rod 31 and the telescopic rod 42 are connected together by the first connecting piece 32, so that the telescopic rod 42 restricts and reinforces the position of the connecting rod 31 via the first connecting piece 32. Then, with the fixed platform 1 as the center, the uprights 51 are erected on the floor slabs on both sides of the fixed platform 1, and the base plate 6 is erected on the bottom surface of the upper floor slab, with the uprights 51 supported on the bottom surface of the base plate 6. The support rod 21 is erected on the surface of the fixed platform 1 and fixed with bolts. The base plate 6 is erected on the bottom surface of the upper post-pouring strip 8 and aligned with the base plate 6 on the bottom surface of the floor slab. The timber 7 is then placed laterally against the bottom surface of the base plate 6. The position of the timber 7 is adjusted so that it is directly above the support rod 21. The support height of the support rod 21 is adjusted so that the positioning block 23 at the top of the support rod 21 is engaged with the side wall of the timber 7. The support rod 21 supports the base plate 6 through the timber 7. At the same time, the branch support frame 22 is adjusted upward and restricted by the screw cylinder. The branch support frame 22 is supported at both ends of the timber 7 by the positioning block 23, thereby strengthening the stability of the timber 7 supporting the base plate 6. Then, the upright 51 and the support rod 21 are connected together by the crossbar 52, thereby strengthening the stability of the support rod 21.

[0028] Compared with related technologies, the one-time molding support frame for ultra-long waterproof post-pouring strip provided by this utility model has the following beneficial effects:

[0029] This utility model provides a one-piece forming support frame for an ultra-long waterproof post-pouring strip. First, the positioning structure 4 is engaged with the edge of the floor slab at the post-pouring strip 8 on the lower floor slab, initially restricting the position of the positioning structure 4. Then, the fixing platform 1 is supported directly above the post-pouring strip 8 and centered on it via the connecting structure 3. Next, the support structure 2 is fixed to the fixing platform 1 with bolts. A base plate 6 is then erected on the bottom surface of the upper post-pouring strip 8, and wooden beams are horizontally erected on the bottom surface of the base plate 6. 7. The support structure 2 supports the bottom plate 6 of the post-cast strip 8 through the wooden beam 7. At the same time, the supporting force of the support structure 2 will squeeze the fixed platform 1, so that the fixed platform 1 squeezes the positioning structure 4 through the connecting structure 3, making the positioning structure 4 more stable. Then, according to the position of the support rod 21, the reinforcement structure 5 is erected on both sides of it, and the reinforcement structure 5 and the support structure 2 are fixedly connected together through the crossbar 52 to enhance the stability of the support structure 2.
