Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carport construction, and particularly relates to a carport steel frame structure. BACKGROUND

[0002] In the process of urbanization, with the increasing number of private vehicles and shared bicycles, the demand for parking spaces is increasing. In order to meet this demand, many areas have begun to build various types of parking sheds in large quantities. The existing carport is mostly made of reinforced concrete structure or light metal frame. Although these traditional structures can meet the basic functional requirements, there are still obvious limitations in service life, construction speed and aesthetics. In addition, due to the shortage of urban land resources, how to efficiently use limited space has become an important consideration factor. The several carport construction schemes commonly used in the current market mainly include traditional brick-concrete structure, cast-in-place concrete column plus roof design and simple frame structure welded by light steel.

[0003] Among them, the brick-concrete structure has high cost and long construction period, which is not suitable for large-scale rapid deployment; the cast-in-place concrete structure is relatively stable, but due to the large amount of on-site pouring operation, it is difficult to realize modular production and assembly; compared with the above two, the light steel welding frame has good economy and flexibility. The conventional light steel welding frame currently mainly includes a carport steel frame, a plurality of tie bars installed at intervals on the carport steel frame, a plurality of purlins fixedly installed at intervals on the tie bars, and a roof installed on the purlins, so as to realize the construction of the carport.

[0004] However, the current carport steel frame construction mode generally has high construction complexity and lacks sufficient safety, especially poor resistance to adverse weather conditions, which brings inconvenience to the users and increases the cost burden of later maintenance. CONTENT OF THE INVENTION

[0005] In order to improve the support strength of the carport steel frame and improve the resistance of the carport to adverse weather conditions, the present application provides a carport steel frame structure.

[0006] The carport steel frame structure provided by the present application adopts the following technical scheme:

[0007] A carport steel frame structure, comprising a plurality of support steel frames arranged at intervals on the ground, a plurality of tie bars arranged at intervals on two adjacent support steel frames and perpendicular to the support steel frames, and a plurality of purlins arranged at intervals on the plurality of tie bars, wherein the support steel frame comprises:

[0008] A column arranged on the ground through a base;

[0009] The cantilever beam is rotatably arranged on the column and the two ends of the cantilever beam are located on the opposite sides of the column, and the column is divided into a boundary line to divide the cantilever beam into a first beam and a second beam, and the length of the first beam is greater than the length of the second beam;

[0010] The first support rod is arranged on one end of the first beam, and the other end of the first support rod is arranged on the end of the column away from the ground;

[0011] The auxiliary support is arranged on the column and supports the second beam, and the cantilever beam is supported and fixed by the column, the first support rod and the auxiliary support.

[0012] By adopting the above technical scheme, the cantilever beam is rotatably arranged on the column, the first support rod supports and fixes the first beam, and the auxiliary support supports and fixes the second beam, so as to disperse the force on the cantilever beam, improve the support strength of the carport steel frame, and improve the resistance of the carport to severe weather conditions.

[0013] Further, the auxiliary support comprises:

[0014] The second support rod is arranged on the base at one end, and the other end of the second support rod is arranged on one end of the second beam;

[0015] The third support rod is arranged on one end of the second beam at one end, and the other end of the third support rod is arranged on the end of the column away from the ground.

[0016] By adopting the above technical scheme, the second support rod disperses the force of the cantilever beam to the base, and the third support rod and the first support rod interact to fix the two ends of the column at the same position, thereby reducing the probability of bending deformation of the column.

[0017] Further, the connecting point of the second support rod and the second beam at one end is located on the end away from the column.

[0018] By adopting the above technical scheme, when the distance between the connecting point of the second support rod and the second beam and the column is greater, the support force required to balance the force of the cantilever beam is smaller, thereby improving the stability of the second support rod.

[0019] Further, the column is provided with a support assembly for supporting the side of the cantilever beam close to the column, and the support assembly comprises:

[0020] The support block abuts against the side wall of the column and supports the bottom of one end of the first beam;

[0021] The locking bolt is arranged on the support block and is threadedly connected to the column.

[0022] By adopting the technical scheme, the support block is fixedly installed on the stand column through the plurality of locking bolts, and the support and fixing effect of the stand column on the cantilever beam is improved through the support block.

[0023] Further, the support block is provided with a U-shaped abutting plate on the side close to the cantilever beam, and the U-shaped abutting plate is abutted on the bottom of the cantilever beam and the side wall close to the bottom.

[0024] By adopting the technical scheme, the U-shaped abutting plate is supported and fixed with the bottom of the cantilever beam and the side wall close to the bottom, so as to facilitate the support and fixing effect of the support block on the cantilever beam.

[0025] Further, the first support rod is rotationally arranged on the stand column and locked through the fixing bolt.

[0026] By adopting the technical scheme, during installation, the fixing bolt is loosened, so that the first support rod is rotationally connected with the stand column, so as to facilitate the adjustment of the relationship between the cantilever beam and the stand column, and when the position adjustment of the cantilever beam is completed, the fixing bolt is screwed, so as to fix the first support rod on the stand column.

[0027] Further, the cross-sectional area of the end of the cantilever beam away from the stand column is smaller than the cross-sectional area of the end of the cantilever beam close to the stand column.

[0028] By adopting the technical scheme, since the force required to be borne by the cantilever beam is greater as the end of the cantilever beam is closer to the stand column, the cross-sectional area of the end of the cantilever beam close to the stand column is made larger, so that the cantilever beam ensures good support effect while reducing its own weight.

[0029] Further, a plurality of installation holes are spaced apart on the first beam, and the tie rod passes through the installation hole and is arranged on the adjacent cantilever beam.

[0030] By adopting the technical scheme, the installation hole is spaced apart on the first beam, so as to facilitate the fixing installation of the tie rod on the cantilever beam.

[0031] In summary, the present application has at least one of the following beneficial technical effects:

[0032] By rotationally installing the cantilever beam on the stand column, the first support rod supports and fixes the first beam, the second support rod and the third support rod jointly act on the second beam to support and fix the second beam, so as to disperse the force on the cantilever beam, improve the support strength of the carport steel frame, and improve the resistance of the carport to severe weather conditions.

The column 2 is a cylindrical structure, and the bottom of the column 2 is fixedly installed on the ground through a base 21. The cantilever beam 3 is rotatably installed on the column 2, and the two ends of the cantilever beam 3 are located on the opposite sides of the column 2, respectively. The rotation axis of the cantilever beam 3 is perpendicular to the axis of the column 2. The cantilever beam 3 is divided into a first beam 31 and a second beam 32 by the column 2 as a boundary line. The length of the first beam 31 is much greater than the length of the second beam 32. The first beam 31 is mainly used for subsequent construction of the carport, and the second beam 32 is mainly used for improving the support and fixing effect of the column 2 on the cantilever beam 3.
