Description

Technical Field

[0001] The invention relates to the technical field of house structures, and in particular to a telescopic steel roof truss flange used for buildings. Background Art

[0002] Many buildings built in the last century have their own unique historical and cultural connotations and are listed as key historical buildings. Their reinforcement and renovation are extremely challenging and difficult for designers and construction workers. The purpose is to preserve their historical features and cultural heritage to the greatest extent without destroying their facade effects and usage functions.

[0003] Especially when the large roofs of old buildings are sloping, in order to maintain the layering and facade of the roof during the roof maintenance process, it is a common practice to set up a steel structure sloping roof. The steel structure sloping roof has the advantages of strong bearing capacity, long service life, high node strength, mature connection method, convenient on-site installation and manufacturing, and low on-site construction difficulty. However, the connection of the traditional finished flange at the connection between the horizontal and longitudinal steel beams of the steel structure sloping roof has become a problem. The longitudinal and lateral parts cannot be installed using traditional rectangular finished flanges, so the roof structure is easy to deform and the deformation joint may become larger, and rainwater and debris will fall from the deformation joint, which poses certain safety hazards.

[0004] It can be seen that the slope roof flange structure used in the existing building structure has great limitations and cannot be well compatible with the installation and fixation of the slope roof structure, resulting in poor stability of the slope roof structure, easy deformation, and failure to achieve rainproof and shielding debris, etc. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Summary of the invention

[0005] In order to overcome at least one of the above-mentioned defects, the present invention proposes a retractable steel roof truss flange for construction. The present invention provides a retractable steel roof truss flange, whose telescopic variability can solve the problem that the flange cannot be connected to the structure due to the enlargement of the deformation joint, and the variability of its end sleeve is suitable for connection with steel beams under any cross section, which can effectively ensure the applicability of its nodes, and its convenient connectivity is easy to install on site, and effectively prevents rainwater and falling objects.

[0006] In order to achieve the above-mentioned purpose, the steel roof truss flange structure disclosed in the present invention can adopt the following technical solutions:

[0007] A telescopic steel roof truss flange for use in buildings comprises a main body forming an upper arch space structure, the lower part of the main body is open and used to cover the connecting seams of the transverse and longitudinal beams of the steel roof truss; the main body extends in a straight line and is fastened to the steel roof truss through a connecting structure at the lower opening of the main body; the outer top surface and the inner top surface of the upper arch space structure are respectively provided with alignment structures for matching the adjacent main bodies.

[0008] The steel roof truss flange disclosed above is mainly used to cover the connection between the crossbeam and the longitudinal beam of the steel roof truss to avoid water leakage or leakage at the connection seam. The flange provided in the present invention can be used to well maintain the building structure with a sloping roof, thereby improving the convenience of the maintenance project of the old building and improving the quality of the maintenance.

[0009] Furthermore, the main structure disclosed in the present invention is not limited to a single one, and it can be constructed into a variety of structural schemes. Here, it is optimized and one feasible option is given: the upper arch space structure includes a top plate, and the two edges of the top plate are respectively provided with inclined side plates, and the angle between the side plate and the top plate is an obtuse angle. When such a scheme is adopted, the top plate and the side plate are integrally formed to form an inverted V-shaped structure or a trapezoidal structure.

[0010] Furthermore, in order to facilitate the connection and fixation between the main body and the steel roof frame, the structure of the side plate is optimized here and one feasible option is given: the lower edge of the side plate is connected with a horizontal connection part, and the connection part is provided with a connection hole. When such a solution is adopted, the connection hole is used to align with the steel roof frame, and the connection part is fixed to the steel roof frame by the connection piece. The connection piece can adopt a variety of solutions, for example, a connection bolt can be used.

[0011] Furthermore, the connection part arrangement in the present invention is not limited to a single one, and a variety of feasible solutions can be adopted. Here, an optimization is made and one feasible option is given: the connection part extends along the lower edge of the side plate and is equal to the length of the side plate, and the connection holes are arranged at intervals on the connection part. When such a solution is adopted, the connection part and the side plate are integrally formed.

[0012] Further, in the present invention, the two main bodies spliced ​​together are connected and matched by an alignment structure. The alignment structure can adopt a variety of feasible solutions, which are not limited to the only one. Here, one feasible option is given: the alignment structure includes an alignment groove, and an alignment strip or alignment block matched with the alignment groove. When such a solution is adopted, the alignment structure keeps the two adjacent matching main bodies in a straight line to achieve telescopic matching.

[0013] Furthermore, in some schemes, the alignment structure may specifically adopt a specific selection, which is optimized and explained here: the alignment structure includes an alignment bar arranged on the upper surface of the top plate, and also includes an alignment groove arranged on the lower surface of the top plate. When two adjacent main bodies are spliced, the alignment bar slides and splices into the alignment groove. When such a scheme is adopted, the alignment groove may adopt a square groove, a triangular oblique groove, a trapezoidal groove and other structures. When the alignment bar corresponds to the alignment bar, the alignment bar can slide in from the end of the alignment groove, and the alignment bar can avoid falling off after sliding with the alignment groove.

[0014] Furthermore, in order to enhance the waterproof effect of the main body, especially the waterproof effect of the main body after assembly, an optimization is made here and one of the feasible options is given: when multiple main bodies are sequentially spliced ​​along the length direction, an end face sealing structure is provided at the end face of the last main body. When such a solution is adopted, the end face of the main body is sealed by the end face sealing structure to prevent water from entering from here and causing leakage, and it can also block some objects; at the same time, the end face sealing structure can also be used to connect the steel roof frame to improve stability.

[0015] Furthermore, in the present invention, the scheme adopted by the end face closing structure is not limited to a single one, and an optimization is made here and one feasible option is given: the end face closing structure includes a closing plate, and a matching structure for connecting the steel roof truss is arranged on the closing plate. When such a scheme is adopted, the shape of the closing plate fits the space structure surrounded by the top plate and the side plate of the main body, and when the closing plate is connected to the main body, the end faces of the top plate and the side plate are closed, and it can be connected and fixed by welding, or by other various methods.

[0016] Furthermore, the matching structure is used to connect the steel roof truss and improve stability. The scheme is not limited to the only one. Here, an optimization is made and one feasible option is given: the matching structure includes a sleeve structure. When such a scheme is adopted, one or more sleeve structures can be provided.

[0017] Furthermore, the main body is used to prevent water and other debris from entering the connection seam of the steel roof frame. In order to protect the main body itself, an optimization is made here and one of the feasible options is given: the surface of the main body is provided with an anti-rust layer. When such a solution is adopted, the anti-rust layer can be coated on the surface of the main body with paint.

[0018] Compared with the prior art, some beneficial effects of the technical solution disclosed in the present invention include:
