Problems solved by technology

However, the PBL shear member needs to open holes and penetrate the steel bars, which greatly increases the construction complexity and is not conducive to construction, and the opening of the holes will increase the height of the ribs, increase the amount of steel, and it is not convenient to lay steel mesh

Embodiment 1

[0024] A shear-resistant and pull-resistant connector of the present invention can fix the steel structure 1 and the concrete structure 2 together to form a whole under common force. The steel structure 1 is I-shaped steel. Of course, other common steel structures can also be selected. .

[0025] like Figure 1-4 As shown, a shear-resistant and pull-out connector includes a plurality of stiffening ribs 3 vertically arranged on the upper surface of a steel structure 1 and a plurality of studs 4 welded on both sides of the stiffening rib 3 . The stiffeners 3 are arranged in parallel along the length direction of the steel structure 1 .

[0026] The specifications of each stud 4 are the same, and each stud 4 is welded side by side and horizontally on both sides of the stiffener 3 along the length direction of the stiffener 3, so as to provide the concrete structure 2 with the shear strength in the horizontal direction and the vertical strength. Lift-off strength in the vertical...

Embodiment 2

[0031] In this embodiment, the structure of a shear-resistant and pull-resistant connector of the present invention is skillfully combined with the structure of the PBL shear member, such as Figure 5 As shown, specifically, several through-holes 5 are opened at the positions corresponding to the two adjacent stiffeners 3, and the same peg 4' penetrates through the corresponding through-holes 5 on the two stiffeners 3. , The studs 4 and the studs 4' are distributed at intervals on both sides of the same stiffener 3, so that a shear-resistant and pull-out resistant connector of the present invention is used in conjunction with a PBL shear member.

Abstract

The invention discloses a shear-resistant and pull-out connecting piece, which comprises a plurality of stiffening ribs vertically arranged on the upper surface of a steel structure and a plurality of studs welded on both sides of the stiffening ribs, the stiffening ribs The plates are arranged in parallel along the length of the steel structure. The invention provides a shear-resistant and pull-out connecting piece, which has a simple structure and is convenient for construction, and at the same time can improve the shear and pull-out resistance between steel and concrete, thereby ensuring reliable interface connection between the two, and ensuring a steel-concrete composite structure of integrity.

Description

technical field [0001] The invention relates to the field of road and bridge construction, in particular to a shear-resistant and pull-out resistant connector. Background technique [0002] The steel-concrete composite structure rationally combines steel and concrete to form a joint force-bearing whole through shear connectors, giving full play to the material characteristics of the two. sex is widely used. Among them, the shear connector provides an indispensable guarantee for ensuring that the interface between steel and concrete does not slip or separate relative to each other. There are many forms of shear connectors, among which stud shear connectors and perforated steel plate connectors (ie PBL shear connectors) are the most common. The stud shear connection has low stiffness and is prone to large deformation during the stress process, which reduces its shear bearing capacity. In addition, the stud shear connection mainly uses the nail cap to resist the lifting forc...
