Description

Technical Field

[0001] This utility model belongs to the field of prefabricated steel structure technology, specifically relating to a prefabricated steel structure for high-rise buildings. Background Technology

[0002] Prefabricated steel structure is a modern construction technology that constructs building structures through factory prefabrication and on-site assembly. This technology combines the advantages of prefabricated buildings and steel structure buildings, and features high construction efficiency, controllable quality, environmental protection and energy saving, and strong flexibility. It is widely used in residential, commercial buildings, industrial plants and other fields.

[0003] The current prefabricated steel beam-column connection structure of high-rise buildings is relatively simple. It is either directly welded or bolted. During the connection process between the beam and the column, a lifting device is needed to lift the beam and then fix it to the column by welding or bolting. Only after the lifting device can the beam be released. During the construction process, the next beam can only be constructed after the previous beam is fixed. This makes the construction efficiency very low.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a prefabricated steel structure for high-rise buildings.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figure 1-8 As shown, an embodiment of the present invention provides a prefabricated steel structure for high-rise buildings, comprising: beams and columns 1, and a beam connection mechanism 2.

[0033] like Figure 1-4 As shown, a mounting head 101 is installed on the beam-column 1, which serves as a support. The mounting head 101 is used to connect the crossbeam 204. An I-shaped slot 102 is carved into the bottom of the beam-column 1, and the beam-column 1 is inserted into the I-shaped slot 102, connecting it to the mounting head 101. A pair of mating seats 103 are fixed to the bottom of the mounting head 101. The mating seats 103 are engaged in the steel grooves on both sides of the beam-column 1, thus securing the beam-column 1 within the mounting head 101.

[0034] like Figure 1-4As shown, multiple corresponding first bolt holes 104 are drilled on the beam-column 1 and the pair of mating seats 103. First bolts 106 are installed in each of the first bolt holes 104, and the beam-column 1 and the mounting head 101 are fixed together by the first bolts 106. Multiple corresponding second bolt holes 105 are drilled on the side walls of the beam-column 1 and the pair of mating seats 103. Second bolts 107 are installed in each of the second bolt holes 105, and the second bolts 107 reinforce the fixation between the beam-column 1 and the mounting head 101.

[0035] like Figure 2-8 As shown, the beam connecting mechanism 2 is mounted on the mounting head 101. The beam connecting mechanism 2 includes a beam 204. A connector 216 is fixed to one end of the beam 204 near the mounting head 101. The connector 216 is snapped onto the mounting head 101. A snap-fit ​​block 201 is fixed to the mounting head 101. A snap-fit ​​groove 205 adapted to the snap-fit ​​block 201 is cut on the connector 216. The beam 204 is snapped onto the mounting head 101 by snapping it into the snap-fit ​​block 201 through the snap-fit ​​groove 205. A support plate 202 is fixed to the bottom of the snap-fit ​​block 201. A pair of support triangle plates 203 are fixed between the bottom of the snap-fit ​​block 201 and the mounting head 101. The support plate 202 supports the beam 204, and the support triangle plates 203 support the support plate 202.

[0036] A fixing component is installed between the connector 216 and the mounting head 101, which fixes the crossbeam 204 to the mounting head 101 from the top. A first connector 212 is installed between the mounting head 101 and the connector 216, and a second connector 213 is installed between two adjacent connectors 216. In beams and columns 1 located at different installation positions, when there is no crossbeam 204 installed on the adjacent side wall of the mounting head 101, the crossbeam 204 is fixed to the mounting head 101 by the first connector 212. When crossbeams 204 are installed on both adjacent side walls of the mounting head 101, the two adjacent crossbeams 204 are fixed by the second connector 213.

[0037] like Figure 4-8As shown, the fixing assembly includes a first fixing plate 208 and a second fixing plate 209. For beams and columns 1 located at different installation positions, when the mounting head 101 has first bolt holes 104 on both sides, the first fixing plate 208 fixes the two crossbeams 204 on opposite sides of the mounting head 101 to the mounting head 101. When the mounting head 101 has a crossbeam 204 on only one side, the second fixing plate 209 fixes the mounting head 101 to the crossbeam 204, with the end of the second fixing plate 209 near the first fixing plate 208 overlapping the first fixing plate 208. The mounting head 101 has a mounting groove 206, into which both the first fixing plate 208 and the second fixing plate 209 are embedded, securing them and preventing rotation.

[0038] like Figure 4-8 As shown, a retaining plate groove 207 is cut into the connector 216. One end of the first fixing plate 208 and the second fixing plate 209, located within the retaining plate groove 207, is fixed with a retaining plate 217. The retaining plate 217 is engaged in the retaining plate groove 207, thereby fixing the connector 216 with either the first fixing plate 208 or the second fixing plate 209. Multiple third bolts 210 are fixed between the retaining plate 217 and the connector 216. Multiple fourth bolts 211 are fixed between the first fixing plate 208, the second fixing plate 209, and the mounting head 101. The third bolts 210 and the fourth bolts 211 fix the first fixing plate 208, the second fixing plate 209, and the connector 216, and also fix the first fixing plate 208, the second fixing plate 209, and the mounting head 101.

[0039] like Figure 4-8 As shown, a fifth bolt 214 is fixed between the first connector 212 and the mounting head 101 and the connector 216, and a sixth bolt 215 is installed between the second connector 213 and an adjacent pair of connectors 216. The first connector 212 is fixed between the mounting head 101 and the connector 216 by the fifth bolt 214, and the second connector 213 is fixed between an adjacent pair of connectors 216 by the sixth bolt 215.

[0040] Working principle: When in use, first fix the beam and column 1 to the designated installation position, then install the mounting head 101 onto the beam and column 1, insert the beam and column 1 into the I-shaped slot 102, and at the same time make the mating seat 103 snap into the steel groove of the beam and column 1. Then, fix the beam and column 1 and the mounting head 101 together with the first bolt 106 and the second bolt 107.

[0041] Then, install the crossbeam 204. Use a lifting device to lift the crossbeam 204, then align the snap-fit ​​groove 205 on the connector 216 with the snap-fit ​​block 201, and snap the snap-fit ​​groove 205 onto the snap-fit ​​block 201. Then, the lifting device can release the crossbeam 204 to assemble the other crossbeams 204. Subsequently, the operator fixes the crossbeam 204 and the mounting head 101. When the mounting head 101 has first bolt holes 104 on both sides, the first fixing plate 208 connects the two crossbeams 204 on opposite sides of the mounting head 101 to the mounting head 101. For mounting head 101, when only one side of the crossbeam 204 is installed, the mounting head 101 is fixed to the crossbeam 204 by the second fixing plate 209. If the crossbeam 204 is already installed on the adjacent side wall of the mounting head 101, the end of the second fixing plate 209 near the first fixing plate 208 is superimposed on the first fixing plate 208. Then, the clamping plate 217 is fixed to the connecting head 216 by the third bolt 210, and the first fixing plate 208, the second fixing plate 209 and the mounting head 101 are fixed by the fourth bolt 211.

[0042] Then, the first connector 212 or the second connector 213 is used to fix the side wall of the crossbeam 204. When there is no crossbeam 204 installed on the adjacent side wall of the mounting head 101, the crossbeam 204 is fixed to the mounting head 101 by the first connector 212 and the fifth bolt 214. When there are crossbeams 204 installed on both adjacent side walls of the mounting head 101, the two adjacent crossbeams 204 are fixed by the second connector 213 and the sixth bolt 215, thus completing the assembly.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
