Description

Technical Field

[0001] The utility model relates to the technical field of construction of cantilevered ends near the edges of composite floor slabs, and more specifically, to a reinforced node for cantilevered ends near the edges of composite floor slabs. Background Art

[0002] Compared with traditional concrete structures, steel structures have natural advantages such as light weight and fast installation. In steel structure projects, floor decking is widely used for laying floor slabs. During the construction stage, the floor decking can directly use corrugated steel plates as formwork to pour concrete. However, for the floor decking at the cantilever end, since the concrete is not formed during the pouring process and cannot reach the designed strength, the bending moment at the cantilever end is large, which easily causes the formwork to deform and cannot be constructed. To solve this problem, the commonly used practice nowadays is to use wall-mounted triangular steel supports, but this type of steel support has a large weight, is difficult to install, and has a high cost, which is not conducive to construction. Utility Model Content

[0003] An object of the present invention is to solve at least the above problems and to provide at least the advantages which will be described below.

[0005] The side mold comprises a horizontal section, a vertical section and a bending section formed by bending in sequence, wherein the horizontal section and the bending section are respectively arranged at two ends of the vertical section, the horizontal section is perpendicular to the vertical section, and the bending section is bent toward the horizontal section; the horizontal section is fixedly overlapped on the top surface of the frame side beam;

[0006] A stiffener, which is fixedly arranged on the horizontal section perpendicular to the axial direction of the frame side beam, and one end of which extends out of the horizontal section and is fixedly connected to the top surface of the frame side beam;

[0007] The pull rod is arranged obliquely, one end of which is fixedly connected to the bending section, and the other end of which is fixedly connected to the stiffening member.

[0008] Preferably, the stiffeners are provided in plurality, and the plurality of stiffeners are arranged at equal intervals along the length direction of the frame side beam.

[0009] Preferably, the distance between two adjacent stiffeners is 500 mm.

[0014] The utility model at least has the following beneficial effects:

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a composite floor slab cantilevered end reinforcement node, which is arranged on the frame edge beam 4 and includes:

[0022] The side mold 1 comprises a horizontal section 11, a vertical section 12 and a bent section 13 which are bent in sequence, wherein the horizontal section 11 and the bent section 13 are respectively arranged at two ends of the vertical section 11, the horizontal section 11 is perpendicular to the vertical section 12, and the bent section 13 is bent toward the horizontal section 11; the horizontal section 11 is fixedly overlapped on the top surface of the frame side beam 4;

[0023] A stiffener 2, which is fixedly arranged on the horizontal section 11 perpendicular to the axial direction of the frame side beam 4, and one end of which extends out of the horizontal section 11 and is fixedly connected to the top surface of the frame side beam 4;

[0024] The pull rod 3 is arranged obliquely, with one end fixedly connected to the bending section 13 and the other end fixedly connected to the stiffening member 2 .

[0025] In this technical solution, the frame side beam 4 is usually made of H-shaped steel, and its top surface is the upper flange of the H-shaped steel. Before pouring the floor deck, the flat side formwork is first bent 90° to form the horizontal section 11 and the vertical section 12, and then the vertical section 12 is bent here to form the folded section 13. The length of the horizontal section is the length of the cantilever end plus the lap length, the length of the vertical section is the thickness of the floor deck, and the length of the folded section is sufficient to ensure a stable connection with the tie rod. The horizontal section 11 is overlapped on the frame side beam 4 to form a casting cavity for the concrete structure of the floor deck. In the casting cavity, the stiffener 2 is respectively connected to the horizontal section 11 and the frame side beam 4, and combined with the tie rod 3 to form a stable support system to ensure that the side formwork at the cantilever end of the floor deck will not be deformed during concrete pouring, and to provide a certain strength for the floor deck. One end of the stiffener 2 connected to the frame side beam 4 may be flush with or exceed the center line of the frame side beam 4, and the other end may not abut against the vertical section 12 under the premise of satisfying the support of the floor slab concrete. Preferably, the side form 1 may be made of a 3mm thick steel plate.

[0026] In another technical solution, the stiffener 2 is provided in plurality, and the plurality of stiffeners 2 are arranged at equal intervals along the length direction of the frame side beam 4. Furthermore, the spacing between two adjacent stiffeners 2 is 500 mm. The tie rods are also provided in plurality, and are arranged one-to-one with the stiffeners. The stability of the reinforced node is ensured by the plurality of stiffeners 2 and the tie rods 3, so as to avoid deformation of the side form 1 under the deadweight load of the upper concrete before the concrete of the floor slab solidifies.

[0027] In another technical solution, the stiffener 2 is an angle steel, and the tie rod 3 is a round steel. The horizontal portion of the stiffener 2 is fixedly connected to the horizontal section 11 and the top surface of the frame side beam 4, and the vertical portion is fixedly connected to the tie rod 3, so that there is a sufficient connection length between the tie rod 3 and the stiffener 3. In actual construction, the side mold 1, the frame side beam 4, the stiffener 2 and the tie rod 3 can all be connected by welding.

[0028] In another technical solution, the bending section 13 is arranged in parallel with the tie rod 3 to increase the connection length between the bending section 13 and the tie rod 3 so that the two are firmly connected. The length of the tie rod 3 is greater than the length of the horizontal section 11 so that the connection between the tie rod 3 and the stiffener 2 is close to the center line of the frame side beam 4, further ensuring the stability of the reinforced node.

[0029] In another technical solution, the overlap width between the horizontal section 11 and the top surface of the frame edge beam 4 is not less than 50 mm. Sufficient overlap width can effectively prevent leakage from the connection between the two during grouting of the floor deck concrete.

[0030] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
