Precautions for post-pouring belt template operation

What should I do with the post-pouring tape template? GB50204-2015 "Code for Acceptance of Construction Quality of Concrete Structure Engineering" has only 15 short words: the formwork and bracket at the post-pouring belt should be set independently. Hubei Wangke Formwork Co., Ltd. introduces that the post-casting belt model is divided into two parts, one is the support model, and the other half is the concrete pouring. Part of the template, the post-pouring belt support is set independently.

Post-pouring tape practice pay attention to the following points:

1. The template and bracket should be designed. The formwork and support should have sufficient bearing capacity, rigidity and stability, and should be able to reliably bear various loads generated during the construction process. Therefore, this model is just a practice. The distance between the vertical poles and the horizontal poles varies from project to project, so you should not copy it.

Attention should be paid to the bracket design: the aspect ratio of the template bracket should not be greater than 3; when the aspect ratio is greater than 3 At the time, stability measures should be added, and the anti-overturning check calculation of the support should be carried out. The step distance of the vertical poles should not be greater than 1.8m; the top-level vertical pole step should be appropriately reduced, and should not be greater than 1.5m.

2, a two-way horizontal rod should be set on the vertical rod every step, and the horizontal rod should be buckled with the vertical rod.

3. A pad should be set at the bottom of the pole.

4. The height of the adjustable bracket from the top horizontal rod should not be greater than 600mm, outside the adjustable bracket screw The diameter should not be less than 36mm, and the insertion depth should not be less than 180mm.

5. At the bottom of the pole, in the horizontal direction, the sweeping pole should be set up in the vertical and horizontal order.

6. Adjacent steel pipe joints cannot be in the same step, and the mutual offset should be greater than 500mm.

Post-pouring belt template support standard practice operation points

1. The post-pouring belt formwork support must adopt an independent design system, which does not affect the installation and disassembly of the full house scaffolding. And the upper and lower poles are placed coaxially, and the post-pouring concrete cannot be removed without pouring; the floor passages should be reserved for frame openings according to the clear position in the plan, and the post-pouring slab surface should be protected and strictly implemented in the implementation process.

2. The upper side opening of the post-pouring belt template of the cast-in-situ slab is consistent with the saw groove of the steel bar position, and the installation is firm. Or use steel wire (board) net to support firmly, add wooden squares on both sides of the upper mouth, and use wooden formwork to seal and protect as a whole, until it opens when the concrete is poured.

3. After pouring the concrete on both sides of the basement roof, a retaining platform will be added, and the basement wall will be pouring behind. The belt is executed according to the design plan.
