Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure buildings, in particular to a steel structure connection node for assembled house construction. Background Art

[0002] Prefabricated steel structure buildings refer to prefabricated buildings whose structural system is composed of steel components. Compared with prefabricated concrete buildings, prefabricated steel structure buildings have the following advantages: 1. There are no on-site cast-in-place nodes, so the installation speed is faster and the construction quality is easier to ensure; 2. Steel structure is a ductile material with better seismic performance; 3. Compared with concrete structure, steel structure has lighter deadweight and lower foundation cost; 4. Steel structure is a recyclable material and is more environmentally friendly; 5. Well-designed steel structure prefabricated buildings are more economical than prefabricated concrete buildings; 6. The cross-section of beams and columns is smaller, and more usable area can be obtained.

[0003] The beam-column connection in the steel structure is an important factor affecting the strength and sense of security of the steel structure building. The current beam-column connection structure is mostly realized by T-plates and high-strength bolts. When the beam is heated or cooled to extend or shorten, the beam will produce lateral pressure or tension on the column. Since the lateral force that the column can withstand is small, in an environment with a large temperature difference between day and night, the thermal expansion and contraction of the beam will cause the column to bend, thereby destroying the structural performance of the column, which in turn affects the safety of the building.

[0004] In summary, the utility model therefore provides a connection node for steel structures in prefabricated building construction to solve the above-mentioned problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a prefabricated building construction steel structure connection node, which is achieved by the following specific technical means:

[0006] A prefabricated steel structure connection node for building construction comprises a connection frame and a crossbeam, wherein the crossbeam is composed of a vertical plate and a wing plate, wherein the wing plates are respectively arranged at the top and bottom of the vertical plate, and the vertical plate and the wing plate are in an I-shaped style, wherein the wing plate is symmetrically provided with two groups of first connection holes on both sides of the vertical plate, and the vertical plate is symmetrically provided with two groups of second connection holes between the two wing plates, wherein the connection frame comprises a fixed plate, wherein two first connection plates are symmetrically provided on one side of the fixed plate, and two pairs of third connection holes are symmetrically provided on the first connection plate, and two second connection plates are symmetrically provided on one side of the fixed plate between the two first connection plates, and two groups of fourth connection holes are symmetrically provided on the second connection plate, and an I-shaped buffer is also provided on the fixed plate between the two first connection plates.

[0007] Furthermore, the first connection hole and the second connection hole are both in strip shape and are parallel to the extension direction of the crossbeam.

[0008] Furthermore, the number of each group of the first connection holes is the same as the number of each group of the third connection holes, and the positions correspond one to one, and the number of each group of the second connection holes is the same as the number of each group of the fourth connection holes, and the positions correspond one to one.

[0009] Furthermore, the shape and size of the I-shaped buffer member are matched with the cross-sectional shape and size of the crossbeam, and the vertical portion in the middle of the I-shaped buffer member passes between the two second connecting plates.

[0010] Furthermore, the I-shaped buffer is made of rubber material.

[0011] Furthermore, a first reinforcing rib plate is provided between a side of the two first connecting plates that is away from each other and the fixed plate, and a second reinforcing rib plate is provided between a side of the two second connecting plates that is away from each other and the fixed plate.

The first connecting hole and the second connecting hole in the strip style allow the crossbeam to have a certain lateral movement space, so that when the crossbeam is heated or cooled to extend or shorten, the crossbeam will not shear the high-strength bolts used for assembling the connecting frame and the crossbeam, and at the same time reduce the lateral force generated by the crossbeam on the column, thereby improving the safety of the connection.

[0022] Among them, the first connecting hole 203 and the second connecting hole 204 are both strip-shaped and parallel to the extension direction of the beam 2, so that there can be a certain lateral movement space between the beam 2 and the connecting frame 1, thereby reducing the impact of the beam 2 on the connecting frame 1 when it is heated or cooled.

[0023] Among them, the number of each group of first connecting holes 203 is the same as the number of each group of third connecting holes 103, and the positions correspond one to one, the number of each group of second connecting holes 204 is the same as the number of each group of fourth connecting holes 105, and the positions correspond one to one, and the connection between the beam 2 and the connecting frame 1 is achieved through the first connecting holes 203, the second connecting holes 204, the third connecting holes 103 and the fourth connecting holes 105.

[0024] The shape and size of the I-shaped buffer member 106 match the cross-sectional shape and size of the beam 2 , and the vertical portion in the middle of the I-shaped buffer member 106 passes between the two second connecting plates 104 .

[0025] Among them, the I-shaped buffer 106 is made of rubber material, and the rubber I-shaped buffer 106 is used for buffering between the beam 2 and the column. On the one hand, the thickness of the I-shaped buffer 106 can control the position of the high-strength bolts in the first connecting hole 203 and the second connecting hole 204 in the strip style when the connecting frame 1 and the beam 2 are installed. On the other hand, it can reduce the impact of the beam 2 on the connecting frame 1 and improve the stability of the connection.

[0028] Specific working principle:

[0029] During the use of the utility model, firstly, a connecting frame 1 is installed at both ends of the cross beam 2 in the utility model respectively. When installing the connecting frame 1, firstly, the end of the cross beam 2 is inserted between the two first connecting plates 102 on the connecting frame 1, and at the same time, during the insertion process, the vertical plate 201 is inserted between the two second connecting plates 104, and then high-strength bolts are respectively passed through the corresponding first connecting holes 203, the third connecting holes 103, the second connecting holes 204, and the fourth connecting holes 105 and fixed.

After the installation is completed, the first connecting holes 203 and the second connecting holes 204 in a strip style and the I-shaped buffer 106 are provided. The first connecting holes 203 and the second connecting holes 204 in a strip style allow the beam 2 to have a certain lateral movement space, so that when the beam 2 is heated or cooled to cause it to elongate or shorten, the beam 2 will not shear the high-strength bolts used for assembling the connecting frame 1 and the beam 2, and at the same time reduce the lateral force generated by the beam 2 on the column, thereby improving the safety of the connection.
