Description

Technical Field

[0001] The present invention relates to the technical field of steel structures, and particularly to an easily installable C-shaped steel structure and an installation method thereof. Background Technique

[0002] C-shaped steels are all automatically processed and formed by a C-shaped steel forming machine. According to the given dimensions of the C-shaped steel, the forming process of the C-shaped steel can be automatically completed. It is widely used for purlins and wall beams of steel structure buildings, and can also be self-assembled into lightweight roof trusses, brackets and other building components. In addition, it can also be used for columns, beams, arms, etc. in mechanical and light industrial manufacturing.

[0003] In the prior art, the installation of C-shaped steels is diverse. For example, two C-shaped steels are installed side by side, stacked back to back, the C-shaped steel is stacked and welded on the H-shaped steel, or the C-shaped steel is used as an arm and installed on the flange of the H-shaped steel. After retrieval, it is found that a Chinese patent (application number: 202411452617.7) provides an installation fastener and an installation method for H-shaped steel and C-shaped steel, including: a galvanized upper buckle plate is abutted on the outer side of the upper flange of the H-shaped steel and on the bottom plate of the C-shaped steel, a galvanized lower buckle plate is abutted on the open side of the C-shaped steel and is detachably connected to the galvanized upper buckle plate, and the bottom plate at the first end of the C-shaped steel is abutted on the inner side of the upper flange of the H-shaped steel through the galvanized upper buckle plate and the galvanized lower buckle plate; the inner side of the U-shaped section of the galvanized U-shaped bolt is abutted on the side of the galvanized upper buckle plate away from the H-shaped steel, and the two threaded sections of the galvanized U-shaped bolt respectively penetrate through the galvanized lower buckle plate and are detachably connected to the galvanized lower buckle plate, and the C-shaped steel is located between the two threaded sections.

[0004] In the above patent, the galvanized upper buckle plate and the galvanized lower buckle plate are detachably connected, which can be installed multiple times and recycled, and there is no welding. After the C-shaped steel is fixed, a ceiling plate can be installed, and there is no gap at the junction of the ceiling plate and the C-shaped steel, realizing the function of a closed space.

[0005] However, after long-term use, the nuts in the above patent are prone to loosening. In addition, if the C-shaped steel is impacted and the impact force is opposite to the rotation direction of the nut locking, it may cause the C-shaped steel to rotate horizontally, affecting its practicality. At the same time, the C-shaped steel is fixed on the H-shaped steel through the installation fastener, and the fixing area is small, and there is no structure to support the C-shaped steel below. If the load at the free end of the C-shaped steel is large, it may cause the C-shaped steel to bend or even break, and the stability is not very good. Therefore, it is necessary to improve the above prior art. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides an easily installable C-shaped steel structure and an installation method thereof, which solve the problems mentioned in the background technique.

[0007] To achieve the above purposes, the present invention is realized through the following technical solutions:

[0008] A C-shaped steel structure convenient for installation, including a C-shaped steel main body, with a number of equally spaced circular side holes opened on the two side plates of the steel main body. A support frame is provided at one end of the steel main body. The support frame presses the top of one end of the steel main body against the upper flange plate of the H-shaped steel, and the lower end of the support frame presses against the lower flange plate of the H-shaped steel. The support frame includes two support rods. The upper ends of the support rods are installed at one end of the steel main body, and the lower ends are welded to the lower flange plate of the H-shaped steel.

[0009] In order to better support the steel main body, the waists of the two support rods are arranged in a cross shape. A long hole is opened in the middle of one of the support rods, and the lower end of the other support rod extends out through the long hole.

[0010] In order to adapt to the different spacings of the two flange plates of the H-shaped steel, the upper ends of the support rods are rotatably installed on the steel main body.

[0011] In order to realize the rotation of the support rod, a circular shaft is rotatably installed in the circular side hole. A shaft sleeve is fixed at the upper end of the support rod, and the shaft sleeve is rotatably installed on the circular shaft. Limit plates are fixed at both ends of the circular shaft extending out of the circular side hole, and the limit plates abut against the outer sides of the two side plates of the steel main body.

[0012] The present invention also discloses an installation method for the above-mentioned C-shaped steel structure convenient for installation, including the following steps:

[0013] Step 1: Rotate the two support rods of the support frame outwards. The support rods drive the shaft sleeve to rotate around the circular shaft, reducing the height of the entire support frame. In this way, the steel main body and the support frame can be placed between the two flange plates of the H-shaped steel, and the steel main body is pushed to the required position.

[0014] Step 2: Rotate the two support rods on the support frame inwards to lift the steel main body, increasing the height of the entire support frame until the top of one end of the steel main body abuts against the upper flange plate of the H-shaped steel and the support rods abut against the lower flange plate of the H-shaped steel.

[0015] Step 3: Weld the lower ends of the support rods. Here, before welding, the lower ends of the support rods can be cut flat with a cutting machine to ensure that the welding area between the support rods and the lower flange plate of the H-shaped steel is large enough. In this way, the support rods are welded to the lower flange plate of the H-shaped steel to realize the installation and support of the entire support frame for the steel main body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: After the steel main body is installed on the H-shaped steel through the support frame, it will not rotate in the horizontal direction. The entire support frame can be divided into upper and lower triangular frames, strengthening the support strength for the steel main body and being more stable. Moreover, before installation, the support frame can adjust the height of the steel main body to cope with the spacing between the two flange plates on different H-shaped steels, improving the practicability of the support frame.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] As Figure 1 shown, the present invention provides a C-shaped steel structure that is convenient for installation, including a C-shaped steel main body 1. A number of equally spaced circular side holes 1-1 are provided on the two side plates of the steel main body 1. A support frame is provided at one end of the steel main body 1. The support frame presses the top of one end of the steel main body 1 against the upper flange plate of the H-shaped steel X, and the lower end of the support frame presses against the lower flange plate of the H-shaped steel X. The support frame includes two support rods 2. The upper ends of the support rods 2 are installed at one end of the steel main body 1, and the lower ends are welded to the lower flange plate of the H-shaped steel X.

[0024] As Figures 2-4 shown, in order to better support the steel main body 1, the waists of the two support rods 2 are arranged in a cross shape. A long opening 2-1 is provided in the middle of one of the support rods 2, and the lower end of the other support rod 2 extends out through the long opening 2-1. The two support rods 2 can divide the support frame into upper and lower triangles. When adjusting the height of the support frame, the two support rods 2 rotate relative to each other in the long opening 2-1. According to the characteristics of the stability of the triangle, the support for the steel main body 1 is strengthened.

[0025] As Figure 2 shown, in order to adapt to the different distances between the two flange plates of the H-shaped steel X, the upper ends of the support rods 2 are rotatably installed on the steel main body 1, so that the two support rods 2 can rotate to adjust the height of the entire support frame.

[0026] As Figures 3-4As shown, in order to achieve the rotation of the support rod 2, a circular shaft 3 is rotatably installed in the circular side hole 1-1. A bushing 4 is fixed to the upper end of the support rod 2, and the bushing 4 is rotatably installed on the circular shaft 3. Limit plates 5 are fixed to both ends of the circular shaft 3 extending out of the circular side hole 1-1, and the limit plates 5 abut against the outer sides of the two side plates of the steel main body 1, so as to prevent the circular shaft 3 from laterally disengaging from the source 1-1.

[0027] The present invention also discloses an installation method for the above-mentioned C-shaped steel structure that is easy to install, including the following steps:

[0028] Step 1: Rotate the two support rods 2 of the support frame outwards. The support rods 2 drive the bushing 4 to rotate around the circular shaft 3, reducing the height of the entire support frame. In this way, the steel main body 1 and the support frame can be placed between the two flange plates of the H-shaped steel X, and the steel main body 1 is pushed to the required position.

[0029] Step 2: Rotate the two support rods 2 on the support frame inwards to lift the steel main body 1 and increase the height of the entire support frame until the top of one end of the steel main body 1 abuts tightly against the upper flange plate of the H-shaped steel X, and the support rods 2 abut tightly against the lower flange plate of the H-shaped steel X.

[0030] Step 3: Weld the lower ends of the support rods 2. Here, before welding, the lower ends of the support rods 2 can be cut flat with a cutting machine to ensure that the welding area between the support rods 2 and the lower flange plate of the H-shaped steel X is large enough, so that the support rods 2 are welded to the lower flange plate of the H-shaped steel X, realizing the installation and support of the entire support frame for the steel main body 1.

[0031] Finally, the most important contribution of the present invention is that after the steel main body 1 is installed on the H-shaped steel X through the support frame, it will not rotate in the horizontal direction. The entire support frame can be divided into upper and lower triangular frames, strengthening the support strength for the steel main body 1 and making it more stable. Moreover, before installation, the support frame can adjust the height of the steel main body 1 to cope with the distance between the two flange plates of different H-shaped steels X, improving the practicality of the support frame.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
