Description

Technical Field

[0001] The utility model relates to the field of steel connection structures, in particular to a connection conversion structure between a cross and a box-shaped steel structure. Background Art

[0002] Cross steel, also known as angle steel, refers to steel with an "L"-shaped cross section. Box steel is a type of steel with a cross-sectional shape similar to a box. Its cross section consists of two parallel upper and lower flange plates and vertical webs on both sides. Their respective advantages and characteristics can be fully utilized through a reasonable combination. In multi-story steel frames and villa structures, box steel is used as the main frame, and cross steel is used to connect and support various parts to form a stable structural system. Usually, welding is used to connect the cross steel and the box steel to form a stable overall structure.

[0003] However, during the welding process, the cross steel needs to be welded to the lining plate at multiple angles, resulting in a larger welding area. After the lining plate is welded, several support plates need to be welded on the lining plate to connect it to the box-type steel structure. The welding support plate connects the two together, which once again increases the welding area. Moreover, the larger the welding area during welding, the greater the angle of deformation of the cross-shaped steel structure or the box-type steel structure, which not only affects the efficiency of assembly, but also leads to increased costs. Utility Model Content

[0004] The main purpose of the utility model is to provide a connection conversion structure between a cross and a box-shaped steel structure, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a connection conversion structure between a cross and a box-type steel structure, including a cross steel and a box steel, a circular connecting steel is arranged between the box steel and the cross steel, the interior of the connecting steel is arranged in a single step shape, the connecting steel is sleeved on the surface of the box steel, the cross steel is inserted into the interior of the connecting steel, steel plates are arranged around the inner wall of the connecting steel, gaps are arranged between the steel plates and the inner wall of the connecting steel, the steel plate is located inside the box steel, the steel plate and the connecting steel are an integrally formed structure, oblique grooves are opened around the inner wall of the connecting steel, the oblique grooves extend to the surface of the steel plate, and the cross steel is inserted into the interior of the oblique grooves.

[0006] A mounting plate is fixedly welded to the edge of the cross steel, the width of the mounting plate is greater than the thickness of the cross steel, and the width of the inclined groove is the same as the width of the mounting plate.

[0007] Triangular connecting plates are installed on both sides of the vertical plate of the cross steel, and one side of the connecting plate is welded to the surface of the mounting plate and the inner wall of the connecting steel.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] 1. In the utility model, by setting connecting steel, steel plate, cross steel and box steel, the connecting steel is sleeved on the surface of the box steel, and the steel plate is stuck inside the box steel at this time. Then the edge of the cross steel is stuck inside the inclined groove. Since the edge of the cross steel is a straight line, it will squeeze the steel plate at the bottom, so that the steel plate is deformed and pressed against the inner wall of the box steel. The deeper the installation position of the cross steel, the more stable the clamping, thereby ensuring the installation of the cross steel and the box steel. This process does not require welding, and the installation is very convenient.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-4As shown, a connection conversion structure between a cross and a box-type steel structure comprises a cross steel 1 and a box steel 2, wherein a circular connecting steel 3 is arranged between the box steel 2 and the cross steel 1, wherein the interior of the connecting steel 3 is arranged in a single step shape, wherein the space at the bottom is larger than the space at the top, wherein the connecting steel 3 is sleeved on the surface of the box steel 2, wherein the cross steel 1 is inserted into the interior of the connecting steel 3, wherein steel plates 4 are arranged around the inner wall of the connecting steel 3, wherein gaps are arranged between the steel plates 4 and the inner wall of the connecting steel 3, wherein the steel plates 4 are located inside the box steel 2, wherein the steel plates 4 and the connecting steel 3 are an integrally formed structure, and the connectivity and deformation capacity of the two are ensured, wherein inclined grooves 5 are arranged around the inner wall of the connecting steel 3, wherein the inclined grooves 5 extend to the surface of the steel plates 4, and wherein the cross steel 1 is inserted into the interior of the inclined grooves 5.

[0018] When installing and connecting the cross steel 1 and the box steel 2, the connecting steel 3 is directly sleeved on the surface of the box steel 2. At this time, the steel plate 4 is stuck in the inside of the box steel 2, and then the edge of the cross steel 1 is inserted along the inside of the inclined groove 5. Since the edge of the cross steel 1 is a straight line, the steel plate 4 at the bottom will be squeezed, so that the steel plate 4 is deformed and pressed against the inner wall of the box steel 2. The deeper the installation position of the cross steel 1, the more stable the clamping, thereby ensuring the installation of the cross steel 1 and the box steel 2. This process does not require welding and is very convenient to install. However, it should be noted that this installation method is not suitable for places with high connection strength.

[0019] A mounting plate 6 is fixedly welded to the edge of the cross steel 1, the width of the mounting plate 6 is greater than the thickness of the cross steel 1, and the width of the inclined groove 5 is the same as the width of the mounting plate 6. When the cross steel 1 is installed, the contact area between the cross steel 1 and the connecting steel 3 is increased, and the pressure exerted by the cross steel 1 on the connecting steel 3 is reduced as much as possible, thereby protecting the connecting steel 3.

[0020] A triangular connecting plate 7 is installed on both sides of the vertical plate of the cross steel 1. The connecting plate 7 is a right-angled triangle. One side of the connecting plate 7 is welded to the surface of the mounting plate 6 and the inner wall of the connecting steel 3. The triangular connecting plate 7 is used to increase the connection stability between the cross steel 1 and the mounting plate 6 and the connecting steel 3, and indirectly ensure the tightness between the cross steel 1 and the box steel 2. At the same time, the welding method is relatively simple, and the required materials are less than traditional welding materials, reducing the cost of connection.

[0021] It should be noted that the utility model is a connection conversion structure between a cross and a box-type steel structure. When in use, when the cross steel 1 and the box steel 2 are installed and connected, the mounting plate 6 is first welded to the edge of the cross steel 1, and the connecting steel 3 is directly sleeved on the surface of the box steel 2. At this time, the steel plate 4 is stuck inside the box steel 2, and then the mounting plate 6 is inserted along the inside of the inclined groove 5. Since the edges of the mounting plate 6 and the cross steel 1 are straight lines, the bottom steel plate 4 will be squeezed, so that the steel plate 4 is deformed and pressed against the inner wall of the box steel 2. The deeper the installation position of the cross steel 1, the more stable the clamping, thereby ensuring the installation of the cross steel 1 and the box steel 2, and then the connecting plate 7 is welded to the surface of the mounting plate 6 and the inner wall of the connecting steel 3 to ensure the tightness between the cross steel 1 and the box steel 2.
