Description

Post-pouring with hanging plate formwork for floors

technical field

The utility model relates to tools and equipment in the technical field of construction, in particular to a hanging board mold for post-casting belts on floors.

Background technique

In order to prevent harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven temperature and shrinkage during construction, according to the requirements of the design or construction specifications, post-casting strips are left at the corresponding positions of the foundation floor, roof, floor, and roof slab to temporarily seal the structure. Divided into several parts, after the internal shrinkage of the components, the post-cast concrete will be poured and tamped after a certain period of time to connect the structure into a whole. Post-processing and post-casting is a troublesome work, especially when the basement, floor slab, and roof slab have a high clearance, in order to ensure the quality of concrete pouring, the formwork support system requires high safety, and sometimes it is necessary to build part of the full hall. Personnel bring difficulties and troubles, and the construction cost is relatively high. Although some technicians use some methods of hanging formwork with wooden formwork, the quality of concrete construction cannot be guaranteed, and some practices violate the requirements of relevant construction quality specifications.

Contents of the invention

The purpose of the utility model is to solve the problems of post-casting belt construction and post-processing troubles, time-consuming, labor-intensive and high-cost defects, and the proposed floor post-casting belt hanging plate formwork.

In order to achieve the above object, the utility model adopts the following technical solutions:

The floor post-casting belt hanging plate formwork is characterized in that it includes a supporting beam, and two symmetrical supporting columns are arranged at the bottom of the supporting beam. On the floor, a connecting screw is fixedly hoisted through a wing nut in the middle of the supporting beam, and fixed and matched with the floor pouring formwork through a tightening nut at the bottom of the connecting screw.

On the basis of above-mentioned technical scheme, can have following further technical scheme:

A hexagonal big head is provided at the bottom of the connecting screw rod, that is, a big-headed screw rod, and the floor pouring formwork is clamped and fitted between the hexagonal big head at the bottom of the connecting screw rod and the tightening nut.

Beneficial effects of the utility model: the utility model can complete the formwork without erecting the support frame twice, has the advantages of simple structure, material saving, labor saving and labor saving, not only improves the working efficiency, but also ensures the construction quality of the concrete structure.

After the floor slab post-cast belt support is removed, install the hanging formwork device, adjust the middle screw, fix the bottom formwork of the floor slab, and then the floor slab post-cast belt concrete can be poured.

detailed description

As shown in Fig. 1 and Fig. 2, the post-casting belt suspension formwork provided by the utility model is characterized in that it includes a square tube support beam 6, and the square tube support beam 6 is horizontally arranged between two formed floor slabs 2 to reserve On the upper part of the crack 3 in the post-cast belt of the floor, two symmetrical support columns 7 are arranged at the bottom of the support beam 6, and the two support columns 7 at the bottom of the support beam 6 respectively support and fix the floor slab poured and formed on both sides of the crack 3 of the post-cast belt 2, the middle part of the support beam 6 is fixed and hoisted with a connecting screw 4 through the wing nut 5. The connecting screw 4 is a big-headed screw, and the lower part of the connecting screw 4 penetrates and fits between the two formed floors 2 to reserve a post-casting belt for the floor. On the floor pouring formwork 1 at the crack 3, a hexagonal big head 4a is provided at the bottom of the connecting screw 4, and a tightening nut 8 is fitted on the upper part of the hexagonal big head 4a, and the floor pouring formwork 1 is clamped and matched with the hexagonal big head 4a at the bottom of the connecting screw 4 and the tightening nut 8.

After the floor slab post-cast belt support is removed, install the hanging formwork device, adjust the middle screw, fix the bottom formwork of the floor slab, and then the floor slab post-cast belt concrete can be poured.

The utility model is not limited to the above-mentioned embodiments, and other structural designs obtained by adopting the same or similar structures as the above-mentioned embodiments of the utility model are within the scope of protection of the utility model.
