Description

Screwless combined angle steel structure

This creation is about a screw-free combined angle steel structure, especially refers to a kind of auxiliary positioning during use to prevent the situation that the cross bar and the straight bar are separated and falling off under external force collision, and the use of the whole is more increased. Innovative designer of screw-free combined angle steel structure with practical efficiency features.

Press, it is often seen that people use angle steel to form various types of racks for placing and displaying various items, and the angle steel is L-shaped, and several holes are arranged on the surface of the angle steel, so that the first size can be adjusted according to the required size. The angle steel is cut to an appropriate length, and then the angle steel is merged together, and the screw is used to fix the positioning through the holes formed on the surface of each angle steel, and the angle steel is assembled into the desired style; however, the angle steel is in the group Since the connection requires the use of screw fixing components for screw connection, it is extremely inconvenient for its operation.

As a result, an industry has developed a bulletin No. M421748 "Combined Shelf" published on February 1, 2012, which mainly includes: more than four angle steels, which have two side walls adjacent to each other at right angles to make the cross section In the shape of "L", most of the above-mentioned two side walls are formed with coupling holes in the shape of an inverted gourd; more than one shelf support group, each shelf support group is composed of three horizontal bars, and two ends of each horizontal bar are formed respectively More than one clamping column is correspondingly engaged in the coupling hole at the corresponding height on the angle steel, and each cross bar is tied to the upper and lower ends of a vertical portion to form a horizontal portion to form a wavy shape; more than one laminate, It is a rectangular plate body, one side of which extends at a right angle to form a blocking portion, the blocking portion is formed at the bottom of the straight portion to form a horizontal portion, and the outer ends of the straight portion are respectively formed with more than one clamping post, and Matches the joint hole on the angle steel.

However, although the above "combined rack" can achieve the expected effect without using screw components during the assembly process, it is also found in its actual operation and use that the structure has the following disadvantages:

1. Due to the structure, the cross bar is clamped in the binding hole at the corresponding height on the angle steel by the clamping column, so that if the external force collides accidentally, the cross bar is easily detached from the angle steel, resulting in the whole set of racks The collapse occurred, so that there is still room for improvement in the overall structural design.

2. The angle steel and crossbar of the structure are at right angles at each end angle, causing people to be cut at each end angle regardless of the assembly process or use, resulting in their existence. Use safety issues.

The reason is that in view of this, the creators have maintained many years of rich experience in design and development and actual production in the related industry, researched and improved on the existing deficiencies, and provided a screw-free combined angle steel structure in order to achieve better practical value. .

The main purpose of this creation is to provide a screw-free combined angle steel structure, which can be used for auxiliary positioning during use to prevent the situation where the cross bar and the straight bar separate and fall off under external force collision.
