Description

Technical Field

[0001] The invention relates to a concrete structure connector, in particular to a double steel plate-concrete composite structure plate type connector, belonging to the field of building construction. Background Art

[0002] As an important structural form in steel-concrete composite structure, the double steel plate-concrete composite wall panel structure is a structural form formed by connecting the steel plates on both sides and the concrete in the middle through shear connectors, so that the composite structure can play a good overall performance and enhance the shear resistance out of the plane. Through the mutual restraint between the steel plates on both sides and the built-in concrete, the overall structure embodies advantages such as high bearing capacity, good ductility, excellent seismic performance, and advantages in impact resistance and leakage prevention. It is widely used in nuclear containment, explosion-proof walls, polar offshore structures and hull structures.

[0003] The shear connectors currently used have the problem that the cross-bolts cause the steel plates on both sides to be uneven. In the case of non-cross-bolts, the shear connectors have poor shear or tensile resistance. At the same time, the traditional connectors are prone to interface slip due to the small welding interface with the steel plate. The above shortcomings of traditional connectors may cause the shear connectors and steel plates to not work properly together, which may lead to structural failure and cause greater hidden dangers. Summary of the invention

[0004] In order to solve the problems of small welding interface between existing single connector and steel plate, low weld reliability, possible separation of connector and steel plate in the structure, poor tensile and shear resistance of the connector, and reduced structural integrity, the present invention proposes a double steel plate-concrete composite wall panel connector.

[0005] The present invention proposes a double steel plate-concrete composite wall panel connector, comprising two steel plates and a plurality of structural connectors, wherein the plurality of structural connectors are installed between the two steel plates, and the structural connectors include two angle steel connectors, which are arranged opposite to each other, and the outer ends of the two angle steel connectors are respectively fixedly connected to the two steel plates.

[0006] Preferably, the angle steel connector is formed by welding an equilateral angle steel and a rectangular steel plate whose side length is the length of a single side of the equilateral angle steel.

[0007] Preferably, bolt holes are opened on the rectangular steel plate and cylindrical bolts are welded thereon.

[0008] Preferably, the circular holes and bolts of the two opposite angle steel connectors penetrate each other to form left and right limit stops.

[0009] Preferably, the spacing between adjacent structural connectors is at least slightly larger than the width of the equilateral angle steel, so that the upper and lower angle steel connectors can be moved horizontally and connected during construction.

[0010] Preferably, the angle steel connector is fixed to the adjacent steel plates by full double-sided welding of fillet welds.

[0011] The double steel plate-concrete composite wall panel connector of the present invention has the following beneficial effects:

[0012] 1. The present invention has a simple design and is easy to obtain, and can be processed in batches in a steel processing plant, saving time and labor.

[0013] 2. The present invention is easy to process and convenient to construct. The two angle steel connectors are connected up and down to form a whole. While keeping both sides of the steel plate flat, the tensile and shear resistance of the connectors is guaranteed, which greatly enhances the overall performance of the structure.

[0020] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings:

[0021] Specific implementation method 1: See Figure 1-3 The double steel plate-concrete composite wall panel connector described in this embodiment includes two steel plates 1 and a plurality of structural connectors, wherein the plurality of structural connectors are installed between the two steel plates 1, and the structural connectors include two angle steel connectors 2, which are arranged opposite to each other, and the outer ends of the two angle steel connectors 2 are fixedly connected to the two steel plates 1 respectively.

[0022] The angle steel connector 2 is formed by welding an equilateral angle steel and a rectangular steel plate whose side length is the length of a single side of the equilateral angle steel.

[0023] The rectangular steel plate is provided with bolt holes and is welded with cylindrical bolts, wherein the diameter of the circular holes is slightly larger than the diameter of the bolts.

[0024] The angle steel connector 2 is fixed to the adjacent steel plate 1 by full double-sided welding of the fillet weld.

[0025] The circular holes of the two opposite angle steel connectors 2 and the bolts penetrate each other to form left and right limit stops.

[0026] The spacing between adjacent structural connectors is at least slightly larger than the width of the equilateral angle steel, so as to facilitate the translation and connection of the upper and lower angle steel connectors during construction.

[0027] The angle steel connector 2 is composed of an equilateral angle steel and a processed thin steel plate, wherein the processed thin steel plate is processed with a circular hole and a cylindrical bolt, wherein the diameter of the circular hole is slightly larger than the diameter of the bolt. The two angle steel connectors 2 are arranged opposite to each other, and the screw rods and the bolt holes are mutually connected.

[0028] A plurality of structural connectors are installed between the two steel plates, and both ends of each angle steel connector 2 on the structural connector are fixedly connected to the two steel plates respectively.

[0029] The working principle of the double steel plate-concrete composite wall panel connector described in the present invention is:

[0030] When the present invention is working, the angle steel connector 2 is welded to one side of the steel plate 1. The spacing between the angle steel connectors 2 on the same steel plate 1 is at least slightly larger than the width of the equilateral angle steel. When the steel plates 1 on both sides are spliced, the angle steel connectors 2 on the two steel plates 1 are first staggered, and then the upper and lower angle steel connectors 2 are translated and connected. After each angle steel connector 2 is connected to each other, the two steel plates 1 and the structural connector form a stable whole, which is used as a concrete pouring template to pour concrete. After the concrete hardens, a double steel plate-concrete composite wall panel is formed, which is put into use in the project as a construction module unit.

[0031] The welding work of the steel plate 1 and the angle steel connector 2 in the present structure can be completed in the prefabricated component factory, and then the welded steel plate 1 processed parts are transported to the site for installation and connection, and finally the concrete is poured on site.

[0032] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. It can also be a reasonable combination of the features recorded in the above embodiments.
