Description

Reinforcement device for beamless floor column cap formwork

technical field

The utility model relates to the construction field, in particular to a reinforcement device for a column cap formwork of a beamless floor slab.

Background technique

At present, beamless floor structures are used in more and more buildings, especially in building structures with functions such as garages and shopping malls. In order to ensure the clear floor height, column caps are often used to support the upper floor, which greatly reduces the frame. Effect of beams on storey height.

The traditional way of supporting the formwork is to use diagonal braces and counter-drawing screws for reinforcement. In the reinforcement of the formwork on the side of the column cap, due to the inclination of the formwork, it often leads to quality problems such as lax seams and mold leakage. At the same time, it is necessary to Drill holes in the formwork on the side of the column cap and pass through the tensioning screws. Especially when there are many tensioning screws, the formwork on the side of the column cap will have more holes, and the formwork cannot be used effectively. Secondary cleaning is required, and the construction is complex, time-consuming and labor-intensive.

Contents of the invention

The technical problem to be solved by the utility model is to provide a beamless floor column cap formwork reinforcing device which is convenient for disassembly and assembly, safe and reliable.

The technical scheme adopted by the utility model to solve the technical problem is: to construct a beamless floor column cap formwork reinforcement device, including floor support frame, column cap diagonal brace, adjustable top support, floor wooden square, floor formwork, column cap Hoops, column cap back corrugated wood square and column cap side formwork, the floor support frame is fixed on the lower floor, the column cap diagonal brace is perpendicular to the column cap side formwork and connected with the floor support frame by fasteners, and the adjustable jack is installed on the floor The support frame and the top of the column cap diagonal bracing respectively withstand the wooden square of the floor and the column cap hoop. The column cap hoop consists of four steel pipes connected by right-angle fasteners. The wooden square is fixedly connected with the floor formwork, and the corrugated wooden square at the back of the column cap is fixedly connected with the side formwork of the column cap.

In the above scheme, the wooden square of the floor slab is fixedly connected with the floor formwork by iron nails.

In the above scheme, the back corrugated wood square of the column cap is fixedly connected with the side formwork of the column cap by iron nails.

In the above solution, the floor formwork and the column cap side formwork are spliced after chamfering at the joint.

In the above solution, the adjustable jack is U-shaped.

Implementing the beamless floor column cap template reinforcement device of the present utility model has the following beneficial effects:

1. When the column cap is reinforced, it is often necessary to set the opposite pull screw; the utility model uses the column cap hoop for reinforcement, without the need to thread the opposite pull screw separately, and saves the process of drilling holes on the side formwork of the column cap and piercing the opposite pull screw, and there is no sawdust generated, reducing costs;

2. The traditional column cap reinforcement method requires a lot of column cap braces. At least 4 column cap braces are required on one side, and a total of 16 braces are required on the four sides. It is more complicated, consumes more materials, and is time-consuming and laborious. In view of this situation, the utility model adopts a column cap hoop for reinforcement, and the column cap hoop forms a rigid whole, and the formwork is not easily deformed.

3. The diagonal brace of the column cap is directly supported on the column cap hoop instead of being supported on the square wood on the back of the column cap. The combination of the column cap diagonal brace and the column cap hoop cleverly forms a "hanger", and the column cap diagonal brace A whole is formed between them, and the column cap diagonal brace can simultaneously bear the vertical force and the horizontal force, firmly fix the column cap hoop, and prevent the column cap hoop from moving down.
