Abstract
Description
Technical Field
[0001] The utility model relates to the field of steel structure factory building construction, in particular to a fully assembled building construction system using gutters as tie rods. Background Art
[0002] Traditional steel structure workshops transfer axial loads through horizontal tie rods set along the longitudinal direction of the building; the organized drainage function of the workshop is undertaken by the inner or outer gutters. The gutter wall thickness is only 1mm. In a humid environment, steel is prone to corrosion, penetrating the thin wall and affecting the drainage function. At the same time, the gutters are usually connected by spot welding. The welding stress causes the gutters to deform, and the welds are prone to leakage and accelerated corrosion. In addition, during the construction process, the tie rods and the drainage gutters are prone to conflict in position during the design deepening process, but this point is usually ignored. Utility Model Content
[0003] (I) Problem to be solved: The purpose of the utility model is to provide a fully assembled building construction system using gutters as tie rods, so as to simplify the current steel structure plant construction process and improve the corrosion resistance of the gutters.
[0004] (II) Technical Solution: To achieve the above purpose, the utility model provides a technical solution: a fully assembled building construction system using the gutter as a tie rod, as a horizontal support, arranged along the steel column to transmit the axial load. The gutter is made of U-shaped steel.
[0005] Furthermore, the wall thickness of the U-shaped steel is greater than 3 mm, and the cross-sectional dimensions are determined according to the local rainfall, wherein the cross-sectional web width needs to be smaller than the column width. Based on the slenderness ratio verification and the overall strength stability verification, the gutter also serves as a horizontal force transmission member of the roof support system.
[0006] Furthermore, the gutter is arranged along the steel column, and the connection method between the gutter and the adjacent steel column is bolt connection, and the distance from the center of the bolt connection opening to the edge of the plate must be greater than or equal to 1.5 times the hole diameter; the center-to-center distance of the hole must be greater than 3 times the hole diameter and less than 8 times the hole diameter.
[0007] Furthermore, rubber pads with holes are arranged between each gutter section, between the gutter end and the steel plate, and between the gutter drainage hole and the rainwater pipe. The rubber pads are 3 mm thick and then bolted together. The elastic deformation of the rubber is used to fill the connecting gaps to increase the density of the interface.
[0008] The utility model proposes a fully assembled building construction system using gutters as tie rods, which has the following beneficial effects:
[0009] 1. When building a steel structure workshop, directly install U-shaped steel between columns instead of tie rods to avoid component position conflicts during the design process and simplify the construction process.
[0010] 2. Ensure the longitudinal rigidity of the steel structure factory while improving the drainage function and corrosion resistance of the gutter. BRIEF DESCRIPTION OF THE DRAWINGS
