[0028] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0029] refer to Figure 1-2 A specific embodiment of the present invention provides an H-shaped steel and C-shaped steel mounting fastener, wherein a plurality of C-shaped steels 4 are detachably connected to the H-shaped steel through a plurality of mounting fasteners, and the mounting fasteners include:

[0030] A galvanized upper gusset plate 1, which is in contact with the outer side surface of the upper flange of the H-shaped steel and the bottom plate of the C-shaped steel 4;

[0031] The galvanized lower gusset plate 2 abuts against the open side of the C-shaped steel 4 and is detachably connected to the galvanized upper gusset plate 1. The bottom plate of the first end of the C-shaped steel 4 abuts against the inner side surface of the upper flange of the H-shaped steel through the galvanized upper gusset plate 1 and the galvanized lower gusset plate 2.

[0032] Generally, the installation of C-shaped steel 4 on H-shaped steel is usually welded, and then the fasteners are installed, and then the ceiling panel is installed. The installation of fasteners is not very applicable in some specific areas, such as IT computer rooms. The airtightness requirements inside the computer room are high, so the ordinary C-shaped steel 4 fastener installation method is not very applicable. In the present application, the C-shaped steel 4 is clamped on the inner side of the upper flange of the H-shaped steel by using a galvanized upper gusset plate 1 and a galvanized lower gusset plate 2; wherein the galvanized upper gusset plate 1 and the galvanized lower gusset plate 2 are connected in a detachable manner, which can be installed multiple times and recycled without welding; after the C-shaped steel 4 is fixed, the ceiling panel can be installed, and there is no gap at the junction of the ceiling panel and the C-shaped steel 4, thereby achieving the effect of a closed space.

[0033] Further optimization plans also include:

[0034] Bolt assembly: the galvanized upper gusset plate 1 and the galvanized lower gusset plate 2 are detachably connected via the bolt assembly.

[0035] The main function of the bolt assembly is to connect the galvanized upper gusset plate 1 and the galvanized lower gusset plate 2.

[0036] To further optimize the solution, the bolt assembly includes:

[0037] The galvanized upper gusset plate 1 is detachably connected to the galvanized lower gusset plate 2 by means of the fastening bolts.

[0038] The galvanized upper gusset plate 1 and the galvanized lower gusset plate 2 can be detachably connected by tightening the bolts, so as to facilitate reuse.

[0039] Further optimization scheme, fastening bolts include:

[0040] The galvanized U-shaped bolt 3 has its U-shaped section inner side abutted against the side of the galvanized upper gusset plate 1 away from the H-shaped steel. The two sets of threaded sections of the galvanized U-shaped bolt 3 respectively penetrate the galvanized lower gusset plate 2 and are detachably connected to the galvanized lower gusset plate 2. The C-shaped steel 4 is located between the two sets of threaded sections.

[0041] The galvanized U-shaped bolt 3 is divided into a U-shaped section and a threaded section fixedly connected to the two ends of the U-shaped section. The galvanized U-shaped bolt 3 passes through both sides of the galvanized upper gusset plate 1 and is detachably connected to the galvanized lower gusset plate 2. The U-shaped section is squeezed on the galvanized upper gusset plate 1, the outer side surface of the upper flange of the H-shaped steel and the bottom plate of the C-shaped steel 4 in turn, and the galvanized lower gusset plate 2 is squeezed on the opening side of the C-shaped steel 4.

[0042] Further optimization plans also include:

[0043] Nuts 5, two groups of nuts 5 abut against the side of the galvanized lower gusset plate 2 away from the C-shaped steel 4, and are threadedly connected with the two groups of threaded sections.

[0044] By threading the nut 5 with the galvanized U-bolt 3, a detachable connection between the galvanized upper gusset plate 1 and the galvanized lower gusset plate 2 can be achieved.

[0045] Further optimization plans also include:

[0046] The groove 6 is provided on the side of the galvanized upper gusset plate 1 away from the H-shaped steel and is arranged corresponding to the bottom plate of the C-shaped steel 4 . The inner side of the U-shaped section abuts against and fits in the groove 6 .

[0047] The main function of the groove 6 is to limit the galvanized U-shaped bolt 3, which passes through the galvanized lower buckle plate 2, thereby preventing the galvanized upper buckle plate 1 or the galvanized lower buckle plate 2 from shifting during the installation process.

[0048] Further optimization plans also include:

[0049] The first extension plate 7 is fixedly connected to a side of the groove 6 away from the H-shaped steel and abuts against the bottom plate of the C-shaped steel 4 .

[0050] The main function of the first extension plate 7 is to make the galvanized upper gusset plate 1 more stably abut against the outer surface of the upper flange of the H-shaped steel and the bottom plate of the C-shaped steel 4, so as to ensure the installation stability of the H-shaped steel and the C-shaped steel 4.

[0051] Further optimization plans also include:

[0052] The second extension plate 8 is fixedly connected to one end of the galvanized lower gusset plate 2 away from the H-shaped steel.

[0053] The main function of the second extension plate 8 is to make the galvanized lower gusset plate 2 more stably abut against the open side of the C-shaped steel 4, thereby ensuring the installation stability of the H-shaped steel and the C-shaped steel 4.

[0054] A method for installing H-shaped steel and C-shaped steel mounting fasteners is used to install the above-mentioned H-shaped steel and C-shaped steel 4 mounting fasteners, and the installation steps are as follows:

[0055] Step 1: Lift the first end of the C-shaped steel 4 through the galvanized lower gusset plate 2 and move it closer to the inner side of the upper flange of the H-shaped steel; make the bottom plate of the C-shaped steel 4 close to the inner side of the upper flange of the H-shaped steel and maintain this action;

[0056] Step 2: Place the galvanized upper gusset plate 1 on the outer side of the upper flange of the H-shaped steel. The galvanized upper gusset plate 1 is attached to the outer side of the upper flange of the H-shaped steel and the bottom plate of the C-shaped steel 4, and corresponds to the galvanized lower gusset plate 2;

[0057] Step 3: Clamp the galvanized upper gusset plate 1 and the galvanized lower gusset plate 2, install the C-shaped steel 4 on the H-shaped steel, and then install the ceiling plate on the C-shaped steel 4. There is no gap at the junction of the ceiling plate and the C-shaped steel 4, so as to achieve the effect of a closed space.

[0058] To further optimize the solution, in step one, the first end of the C-shaped steel 4 is closely attached to the inner side of the upper flange of the H-shaped steel and is arranged close to the web of the H-shaped steel.

[0059] Such an arrangement can ensure the installation stability of the H-shaped steel and the C-shaped steel 4 .
