Description

A kind of reinforcement device of floor slab edge beam formwork

technical field

The utility model relates to a reinforcement device for a formwork of a floor slab side beam, which belongs to the field of building formwork engineering.

Background technique

The wall formwork must ensure the thickness of the side beams. It must not only have tensioning tools to prevent the thickness from increasing, but also support tools to prevent the thickness from becoming smaller. The correct cross-sectional size is an important condition for the qualified quality of the side beams. The traditional side beam reinforcement method is to use supporting tools and tensioning tools under the side beams. This method has three shortcomings. On the one hand, the supporting tools and tensioning tools are separated, that is, they play a supporting role in the formwork There is no corresponding relationship between tools and tools that act as reinforcement outside the formwork. If there is no support tool at the position where the tool is tightened, the thickness of the edge beam at the position will become smaller when the tool is tightened. During the operation, many support tools will fall off or It is no longer in a horizontal position, which will cause the size of the side beam to be locally reduced and affect the forming quality of the side beam. Second, this kind of reinforcement tool cannot be used for turnover. After the formwork is poured with concrete, the support tool will remain in the formwork. The third aspect , the reinforced position is far away from the top of the side beam, and it is not easy to control the thickness of the top of the side beam.

Utility model content

The technical problem to be solved by the utility model is to study a reinforcement device for the formwork of the side beam of the floor to solve the problem that the supporting tool and the tensioning tool in the prior art are separated, which may easily cause the size of the side beam to be locally reduced and affect the forming quality of the side beam. The problem is that the strengthening tools cannot be recycled and used, and the thickness of the upper edge of the side beam is not easy to control.

The technical scheme of the utility model is: a floor slab edge beam formwork reinforcement device, including a butterfly buckle and a screw rod, the concrete block is embedded in the floor slab, the concrete block is provided with an opening, and the screw rod is a 90-degree bending part. One end is clamped in the opening of the concrete block, the other end passes through the formwork above the floor, the inner nut is screwed on the screw and is close to the inside of the formwork, and the screw on the outside of the formwork is sequentially sleeved with square timber, buckled with butterfly buckle and screw thread Attach the outer nut. The reinforcing device is located above the floor, and other parts of the device except the concrete block can be used in a cycle. When in use, tighten the outer nut inwardly, push the butterfly buckle to compress the square wood and further compress the formwork, the outer nut prevents the section of the side beam from becoming thicker, and the inner nut prevents the section of the side beam from becoming thinner.

Preferably, the concrete block is integrally fixed with the bottom form of the floor slab, so that the position of the concrete block is more stable and the firmness of the whole device is improved.

Preferably, the height of the concrete block is equal to the thickness of the floor slab, and the concrete block remains in the floor slab after the reinforcement is completed. After the screw is taken out, grouting material is injected into the opening of the concrete block to make the floor slab structure complete.

Preferably, the lower part of the concrete block is fixed by iron nails, and the iron nails are buried when the concrete block is made, and the concrete block is fixed on the floor bottom form by iron nails, so that the position of the concrete block is more stable.

Preferably, the diagonal brace is welded to the bending part of the screw to reinforce the screw, so as to avoid affecting the reinforcement accuracy due to the change of the angle force at the bending part of the screw during the subsequent reinforcement process.

The beneficial effect of the utility model is: to design a reinforcement device for the formwork of the floor slab side beam, compared with the prior art, the advantages mainly include:

1. The reinforced position of the device of the utility model is above the floor, and other parts of the device except the concrete blocks can be recycled, which saves costs and solves the problem that some devices in the prior art cannot be recycled;

2. The concrete block at the fixed point of the utility model device and the floor slab are poured as a whole, and the bottom is fixed by iron nails, which increases the firmness of the whole device and improves the stability of the formwork reinforcement. It acts as a reinforcement and improves the stability of the entire device;

3. The utility model device tightens the outer nut, pushes the butterfly buckle to compress the square wood and further compresses the formwork, the outer nut prevents the section of the side beam from becoming thicker, and the inner nut prevents the section of the side beam from becoming thinner. The quality effect of side beam section is good;

In addition, the device has a simple structure and is easy to use. The height of the concrete blocks is equal to the thickness of the side beams. After use, the openings of the concrete blocks are filled to make the floor structure complete.
