TECHNICAL FIELD
[0001] The present application relates to the technical field of building construction, in particular to an inlaid node of a steel structure building and a construction method. BACKGROUND
[0002] Fabricated steel structure system refers to a building produced by transporting a housing unit or a component produced according to unified and standard building part specifications to the construction site for assembly. With the development of building requirements and the increasing complexity of steel structure building functions, the building structure has also changed significantly.
[0003] In the design of fabricated steel structure buildings, the steel structure node directly affects the construction speed and the degree of assembly of the structure. In the prior art, field welding is often used at the node of a steel structure building. Although this connection method is a rigid connection, the node has poor ductility and is prone to brittle failure in an earthquake. In addition, field welding is required, which greatly affects the construction speed and quality, and is not suitable for multi-story fabricated steel structure buildings. At the same time, due to the large welding area, large residual stress is easily generated, which affects the stress performance of the node. A fabricated double-flange beam-column bolt node connection device with a cover plate is disclosed in Chinese Patent No. CN105888060A, which includes a plurality of flange plate splicing plates. The flange plate and the steel beam are connected by bolts, and the splicing plate and the steel beam are connected by bolts, thereby avoiding the influence of field welding to some extent.
[0004] The inventors have found that the prior art at least has the following defects: In order to ensure the connection strength, construction personnel usually use more bolts for fixation. However, due to the increase in the number of bolts, the probability of bolt falling off at the node also increases, thereby causing a large safety hazard. SUMMARY
[0005] The embodiments of the present application provide an inlaid node of a steel structure building and a construction method, which solve the safety hazard caused by bolt falling off at the node connection of a steel structure building in the prior art.
[0006] To solve the above technical problems, the present application adopts the following technical scheme: an inlaid node of a steel structure building, comprising a vertical beam and a horizontal beam matched with the vertical beam, a connecting beam is fixed on one side of the vertical beam, the connecting beam can be connected with the horizontal beam, a sleeve is arranged at the end of the horizontal beam, the sleeve is nested on the outer periphery of the horizontal beam and can move relative to the horizontal beam, a fixed plate is arranged at one end of the sleeve, and the fixed plate can be fixed with the side surface of the vertical beam.
[0007] Since the outer periphery of the horizontal beam is movably provided with the sleeve, when the horizontal beam is connected with the connecting beam, the sleeve can cover the bolts at the connecting position of the horizontal beam and the connecting beam by moving, which can effectively avoid the loosening and falling off of the bolts at the connecting position, thereby avoiding the safety hazard caused thereby.
[0008] Further, the bottom of the connecting beam has a lower flange, and the lower flange is fixed to the beam body of the cross beam by bolts; the top of the end of the cross beam has an upper flange, and the upper flange is fixed to the beam body of the connecting beam by bolts; thus, the cross beam and the connecting beam are more convenient to butt joint.
[0009] Further, the connecting beam and the cross beam are both I-shaped steel, and a cladding plate is arranged on both sides of the butt joint of the connecting beam and the cross beam, and the cladding plate is fixed to the web of the corresponding I-shaped steel by bolts.
[0010] Further, the upper and lower edges of one end of the sleeve each have a fixing plate, and the fixing plate is provided with a through hole and can be fixed to the vertical beam by bolts.
[0011] Further, the upper and lower bottom surfaces of the sleeve are each provided with a rib plate between the fixing plate; thus, the strength of the sleeve can be enhanced, and the protection performance of the sleeve can be improved.
[0012] Further, the fixing plate has a vertical strip-shaped hole; thus, the hole position on the fixing plate can be aligned with the corresponding empty position on the vertical beam, and the fixing of the sleeve is facilitated.
[0013] Further, the upper surface and the lower surface of the inner cavity of the sleeve are each provided with a strip-shaped groove, and the groove transversely penetrates the two end surfaces of the sleeve; the groove can avoid the interference between the bolts at the upper flange and the lower flange and the inner wall of the sleeve.
[0014] Further, the construction method of the inlaid node of the steel structure building comprises the following steps:
[0015] Step one, aligning the end of the cross beam with the end of the connecting beam, fixing the lower flange to the beam body of the cross beam by bolts, and fixing the upper flange to the beam body of the connecting beam by bolts;
[0016] Step two, installing and placing the cladding plate on both sides of the web at the butt joint of the cross beam and the connecting beam, and fixing the cladding plate by bolts;
[0017] Step three, moving the sleeve horizontally, and fixing the fixing plate of the sleeve to the side surface of the vertical beam.
[0018] Through the above technical solutions, the present application has at least the following technical effects or advantages:
[0019] 1. Since the outer periphery of the cross beam is movably provided with a sleeve, when the cross beam is connected to the connecting beam, the bolts at the connecting position of the cross beam and the connecting beam can be covered by moving the sleeve, and the loosening and falling off of the bolts at the connecting position can be effectively avoided, and the safety hazards caused thereby can be avoided.
[0020] 2. Since the lower flange is integrated with the connecting beam and can be fixed to the beam body of the crossbeam with bolts, and the upper flange is integrated with the crossbeam and can be fixed to the beam body of the connecting beam with bolts, it is more convenient to connect the crossbeam and the connecting beam.
[0021] 3. Because the upper and lower bottom surfaces of the sleeve are provided with ribs between them and the fixed plate, the strength of the sleeve can be enhanced and the protective performance of the sleeve can be improved.
[0022] 4. Because the fixing plate has vertical slots, it is easy to align the holes on the fixing plate with the corresponding slots on the vertical beam, which facilitates the fixing of the sleeve.
[0023] 5. Because the inner cavity of the sleeve has a groove that runs laterally through both end faces, interference between the bolts at the upper and lower flanges and the inner wall of the sleeve can be avoided. Attached Figure Description

[0032] Connecting beam 3 is I-beam, one end of connecting beam 3 is welded and fixed with vertical beam 1, the other end of connecting beam 3 has lower flange 6, and the lower flange 6 is integrated with the bottom of connecting beam 3 and extends away from vertical beam 1. Boltholes are provided on the plate surface of the extended lower flange 6, and correspondingly, boltholes are also provided on the lower bottom surface of cross beam 2, so that the lower bottom surface of cross beam 2 can be fixed with the lower flange 6 at one end of connecting beam 3 by bolts.
[0033] Cross beam 2 is I-beam, upper flange 7 is provided at the end of cross beam 2 abutting against connecting beam 3, the upper flange 7 is integrated with the top of cross beam 2 and extends towards vertical beam 1. Boltholes are provided on the plate surface of the extended upper flange 7, and correspondingly, boltholes are also provided on the upper bottom surface of connecting beam 3, so that the upper flange 7 at the end of cross beam 2 can be fixed with connecting beam 3 by bolts. After the lower flange 6 is fixed with the lower bottom surface of cross beam 2 and the upper flange 7 is fixed with the upper flange 7 of connecting beam 3, cross beam 2 can be preliminarily abutted and fixed with cross beam 2.
[0034] Paste plate 8 is also provided on both sides of the abutting position of connecting beam 3 and cross beam 2, and the paste plate 8 is provided with a plurality of through holes penetrating the plate surface, and correspondingly, a plurality of through holes are also provided on the web plate at the abutting position of connecting beam 3 and cross beam 2. When the hole positions of the through holes on the paste plate 8 coincide with the hole positions of the through holes on the web plate, the paste plate 8 is fixed by penetrating through bolts.
[0035] Sleeve 4 is located at the end of cross beam 2, and cross beam 2 is located in the cavity of sleeve 4, and when sleeve 4 moves along cross beam 2, sleeve 4 can be separated from cross beam 2. The end of sleeve 4 close to vertical beam 1 has fixed plate 5, and the fixed plate 5 is integrated with the upper and lower edges of sleeve 4, respectively. Through holes are provided on the fixed plate 5, and correspondingly, boltholes or through holes are provided on the side surface of vertical beam 1, so that the fixed plate 5 can be fixed with the side surface of vertical beam 1 by bolts.
[0036] The through hole on the fixed plate 5 is long strip-shaped and vertically arranged, thereby facilitating the relative fixation of the fixed plate 5 and the vertical beam 1. The rib plate 9 is arranged between the upper and lower bottom surfaces of the sleeve 4 and the fixed plate 5 of the sleeve 4, thereby enhancing the strength of the sleeve 4. The length of the sleeve 4 is greater than the length of the connecting beam 3.

[0041] Step three: after the relative fixation of the horizontal beam 2 and the connecting beam 3, move the sleeve 4 transversely, so that the fixed plate 5 of the sleeve 4 is relatively fixed to the side surface of the vertical beam 1.
[0042] Through the above construction method, the end of the horizontal beam 2 and the end of the connecting beam 3 can be more conveniently and quickly fixed. After the relative fixation of the horizontal beam 2 and the connecting beam 3, the sleeve 4 can cover the bolts at the connecting part, and at the same time, the loosening of the bolts can be avoided, thereby improving the connecting strength and effectively avoiding the safety hazard.
