Steel structure buildings have the advantages of mature structural design, convenient production, comprehensive construction measures, fast construction period, light weight, less waste emissions, and good durability. They have been widely used in the fields of industrial buildings and civil industrial buildings in my country. At the same time, compared with concrete buildings, steel structure buildings have lower carbon emissions. In recent years, the technical research and development and project implementation of steel structures have become increasingly intense, and they have occupied an increasingly important position in my country's construction field.

[0030] The following combination Figure 1-2 This application is described in further detail.

[0031] The present application discloses a quick and easy connection structure for outdoor heat-insulating cantilever beams of assembled steel structures. Figure 1 and Figure 2 , including a connecting member 1, a first end plate 2, a second end plate 3, a glass fiber reinforced plastic block 4 and a stainless steel bolt 5. The first end plate 2 and the second end plate 3 are respectively abutted against the opposite ends of the glass fiber reinforced plastic block 4 and fixed by the stainless steel bolt 5. The axis of the stainless steel bolt 5 is arranged in the horizontal direction; one end of the connecting member 1 is welded to the flange of the steel column 7, and the other end of the connecting member 1 is welded to the end of the first end plate 2 away from the glass fiber reinforced plastic block 4; the end of the second end plate 3 away from the glass fiber reinforced plastic block 4 is welded to the cantilever steel beam 8.

[0032] Through the cooperation of the connecting piece 1, the first end plate 2, the second end plate 3, the glass fiber reinforced plastic block 4 and the stainless steel bolt 5, the cantilevered steel beam 8 is firmly connected to the flange of the steel column 7, avoiding direct contact between the cantilevered steel beam 8 and the steel column 7. In addition, the heat transfer coefficient of the glass fiber reinforced plastic material is 0.25W / (m 2 ·K), the glass fiber reinforced plastic block 4 is arranged between the cantilevered steel beam 8 and the steel column 7, which can reduce the heat transfer coefficient between the cantilevered steel beam 8 and the steel column 7, effectively reduce the thermal bridge effect, reduce the heat loss of the building, and enhance the energy-saving performance of the assembled steel structure building.

[0033] An installation hole 61 is opened on the building exterior wall 6, and the installation hole 61 passes through the building exterior wall 6, and the axis of the installation hole 61 is set in the horizontal direction; the connecting member 1, the first end plate 2, the second end plate 3 and the fiberglass block 4 are all located in the installation hole 61, and the four sides of the fiberglass block 4 are abutted against the inner wall of the installation hole 61, so that the fiberglass block 4 is firmly installed in the installation hole 61.

[0034] Moreover, the cross-sectional areas of the first end plate 2 and the second end plate 3 are equal to the cross-sectional area of the FRP block 4, so that the connection between the FRP block 4 and the connecting member 1 and the cantilevered steel beam 8 is more stable. In particular, one end of the FRP block 4 close to the cantilevered steel beam 8 protrudes from the outer wall of the building exterior wall 6, avoiding direct contact between the second end plate 3 and the building exterior wall 6, so that the heat of the cantilevered steel beam 8 can neither be further transferred to the steel column 7 nor to the building exterior wall 6, which can further reduce the generation of the thermal bridge effect.

The heat transfer coefficient of the stainless steel material is 15W / (m 2 ·K), and the penetration area of the stainless steel bolt 5 is small, which can reduce the heat transfer coefficient between the steel column 7 and the cantilever steel beam 8.

[0036] A plurality of stainless steel bolts 5 are provided, and the plurality of stainless steel bolts 5 are evenly distributed to ensure the connection stability between the glass fiber reinforced plastic block 4 and the first end plate 2 and the second end plate 3. In this embodiment, the number of stainless steel bolts 5 is 10, and the 10 stainless steel bolts 5 are arranged in two rows along the vertical direction, each row is equipped with 5 stainless steel bolts 5, and the 5 stainless steel bolts 5 in each row are evenly distributed.

[0037] The connecting member 1 is an I-beam, and the web of the connecting member 1 is vertically arranged. One end of the web of the connecting member 1 is vertically welded to the outer side of the flange of the steel column 7, and the other end of the web of the connecting member 1 is vertically welded to the end of the first end plate 2 away from the glass fiber reinforced plastic block 4; and, one end of the two flanges of the connecting member 1 is respectively vertically welded to the outer side of the flange of the steel column 7, and the other end of the two flanges of the connecting member 1 is respectively vertically welded to the end of the first end plate 2 away from the glass fiber reinforced plastic block 4, so as to achieve a stable connection between the steel column 7 and the glass fiber reinforced plastic block 4.

[0038] The outer side of the flange of the steel column 7 abuts against one end of the building exterior wall 6 close to the steel column 7, which is used to improve the connection stability between the cantilevered steel beam 8 and the steel column 7. In order to improve the thermal insulation effect of the building, the gap between the connector 1 and the mounting hole 61 is filled with thermal insulation material 9, which can reduce the contact between the connector 1 and the air, effectively reduce the heat loss of the steel column 7, reduce the energy consumption of the building, and help promote the development of green buildings.

[0039] The implementation principle of the quick and easy connection structure of the outdoor heat-insulating cantilever beam of the prefabricated steel structure steel column disclosed in the embodiment of the present application is as follows: a connecting member 1, a first end plate 2, a second end plate 3, a glass fiber reinforced plastic block 4 and a stainless steel bolt 5 are arranged between the cantilevered steel beam 8 and the steel column 7, the first end plate 2 and the second end plate 3 are respectively clamped at the opposite ends of the glass fiber reinforced plastic block 4 and fixed by the stainless steel bolt 5, and the axis of the stainless steel bolt 5 is arranged in the horizontal direction; one end of the connecting member 1 is welded to the outer side of the flange of the steel column 7, the other end of the connecting member 1 is welded to the end of the first end plate 2 away from the glass fiber reinforced plastic block 4, and the end of the second end plate 3 away from the glass fiber reinforced plastic block 4 is welded to the cantilevered steel beam 8, so as to firmly connect the cantilevered steel beam 8 to the outer side of the flange of the steel column 7; the overall heat transfer coefficient of the present application is reduced by nearly 60%-80% compared with the conventional node structure, which effectively reduces the thermal bridge effect, reduces the heat loss of the building, and enhances the energy-saving performance of the prefabricated steel structure building.
