A large-span floor beam formwork reinforcement structure

Technical Field

The present application relates to the technical field of formwork support for building construction, and in particular to a large-span floor beam formwork reinforcement structure.

Background Art

In the system of cast-in-place floor beams, the formwork is generally fastened by tension screws. At this time, the tension screws need to pass through the cast-in-place wall and the formwork at the same time, and the formwork on both sides of the cast-in-place wall is squeezed and fastened by the extrusion pieces on the tension screws.

Among them, the tension screws are easy to damage the formwork, reducing the turnover times of the formwork, and the opening position of the formwork is prone to leakage, affecting the quality of concrete forming. In the process of disassembling the tension screws, it is sometimes necessary to cut them off and fill the holes on the floor beams. The operation process is cumbersome and there is a risk of external wall leakage. At the same time, the force points of the tension screws are concentrated at one point, and the formwork is prone to deformation at this position.

The end forms 2 are located at both ends of the casting cavity 31 in the length direction. The reinforcement assembly 4 fixes the side form 1 to the base plate 3 on the one hand, and is used to reinforce the side form 1 on both sides of the casting cavity 31 in the length direction on the other hand.

1, 2 and 3, the reinforcement assembly 4 includes a first rib 41, a second rib 42, a diagonal brace 43 and a diagonal brace seat 44, the first rib 41 is fixed to the side of the side mold 1 away from the casting cavity 31 by bolts along the length direction of the casting cavity 31, the second rib 42 is fixed to the side of the side mold 1 away from the casting cavity 31 by bolts along the length direction of the casting cavity 31, and the second rib 42 is located below the first rib 41, and a first slide groove 411 with a T-shaped cross section is opened on the side of the first rib 41 away from the casting cavity 31 along the length direction of the casting cavity 31, and the second rib 42 is located below the first rib 41. A second slide groove 421 with a T-shaped cross section is provided on the side of 42 away from the casting cavity 31 along the length direction of the casting cavity 31. One end of the diagonal support rod 43 slides in the first slide groove 411 along the opening direction of the first slide groove 411 through the first slider 412. The first slider 412 is located in the first slide groove 411 and is consistent with the cross section of the first slide groove 411. One end of the diagonal support rod 43 is rotatably connected to the first slider 412, and the rotation axis is consistent with the opening direction of the first slide groove 411. In the present application, the diagonal support rod 43 is a telescopic rod, and the length of the diagonal support rod 43 is adjusted by bolt tightening.

One end of the diagonal support seat 44 slides in the second slide groove 421 along the opening direction of the second slide groove 421 through the second slider 422. The second slider 422 is located in the second slide groove 421 and has the same cross-section as the second slide groove 421. The bottom of the diagonal support seat 44 contacts the bottom plate 3. When the diagonal support seat 44 slides to a certain position, the diagonal support seat 44 is fixed to the bottom plate 3 by bolts. A clamping block 45 is provided on the upper surface of the diagonal support seat 44. After determining the installation position of the diagonal support seat 44, the personnel adjust the distance of the diagonal support rod 43 so that the end of the diagonal support rod 43 away from the first slider 412 abuts against the side of the clamping block 45 close to the casting cavity 31, thereby completing the installation and reinforcement of the side mold 1.

2 and 3 , in order to increase the support strength of the side mold 1 , a plurality of clamping blocks 45 are provided, and are evenly distributed on the diagonal support seat 44 along a direction perpendicular to the opening of the second slide groove 421 . Personnel adjust the angle between the diagonal support rod 43 and the diagonal support seat 44 through the installation position of the first rib 41 , and a 45° angle is preferably used in the present application.
