[0002] Light steel keel is a metal frame material widely used in the construction industry. It is generally made of galvanized pipes and is widely used in the ceiling of public places such as decoration stores and work shops.

[0003] The light steel keel for suspended ceiling is generally composed of the keel body, hanging rod frame, expansion screw and nut.

[0004] During the specific installation, the expansion screw is first fixed to the top wall of the house through the preset expansion screw, which is the existing technology. Then, the hanger frame is fixed to the expansion screw through the nut. Then, the welded keel body can be hung on the hanger frame. Later, bolts are needed to fix the keel body and the hanger frame.

[0005] At present, when fixing and installing the keel body and the hanger frame on the existing light steel keel for suspended ceilings, bolts are generally passed through preset through-holes on the keel body and the hanger frame, and then the preset nuts are threadedly fixed with the passed bolts. Therefore, an open-end wrench and a screwdriver are required. At the same time, the open-end wrench and the screwdriver need to be turned continuously to fix the bolts and nuts, which is time-consuming and troublesome, and greatly reduces the convenience of hanging and installing the keel body and the hanger frame on the light steel keel for suspended ceilings.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-5 A light steel keel structure that is easy to install includes a keel body 1, a positioning groove 11 is opened on the keel body 1, a hanging rod frame 2 is hung on the keel body 1, the hanging rod frame 2 is provided with an expansion screw 21, a horizontal through-hole 3 and a damping sliding hole 7 are opened on the hanging rod frame 2, a top through-hole 31 is opened in the horizontal through-hole 3, a mounting pressure rod 4 is slidably connected to the hanging rod frame 2, a clamping groove 42 is opened on the mounting pressure rod 4, and a limit plate 41 and a limit block 43 are provided on the mounting pressure rod 4;

[0028] The hanger frame 2 is provided with a fixing block 5, the fixing block 5 is provided with a sliding pin 51, the sliding pin 51 is provided with a pin pull ring 52, and the pin pull ring 52 is provided with a spring 53;

[0029] The hanger frame 2 is provided with an embedding groove 6, in which a positioning pad 61 and a positioning column 62 are provided. Some structures recorded in this patent are commonly used structures of light steel keels for suspended ceilings and are prior art. Some existing structures are not drawn and marked and need not be described in detail.

[0030] The overall structure of the hanger frame 2 is a "G" shape. The installation pressure rod 4 passes through the damping slide 7 and is laterally slidably connected to the hanger frame 2. The inner wall of the damping slide 7 has a damping silicone layer with damping friction elasticity, which prevents the installation pressure rod 4 from sliding freely when not subject to external force.

[0031] The side cross-sections of the transverse through-hole 3 and the damping sliding hole 7 are both rectangular openings and pass through the hanger frame 2 , so as to prevent the installation pressure rod 4 from rotating in the damping sliding hole 7 .

[0032] The top opening 31 is opened at the top of the inner wall of the transverse opening 3 and passes through the transverse opening 3. Figure 4 and Figure 5 When the mounting rod 4 slides to the left, it is ensured that the limiting block 43 passes through the top opening 31 to the left.

[0033] The sliding pin 51 is vertically slidably connected to the fixed block 5, and the pin pull ring 52 is arranged at the lower end of the sliding pin 51. The upper and lower ends of the spring 53 are fixed to the fixed block 5 and the pin pull ring 52 respectively, and combined with the clamping groove 42, it is convenient to elastically and quickly clamp and position the installation pressure rod 4.

[0034] The limit plate 41 is provided at the right end of the mounting rod 4, see Figure 5 When the sliding latch 51 is inserted into the engaging groove 42 , the left end surface of the limiting plate 41 is also in stable limiting contact with the hanger frame 2 .

[0035] The limit block 43 is located at the top of the mounting rod 4. Figure 4 The limit block 43 can prevent the installation pressure rod 4 from slipping out of the damping sliding port 7 to the right.

[0036] The embedding groove 6 and the positioning pad 61 are integrally formed into a group. The front view of the embedding groove 6 and the positioning pad 61 is a U-shaped structure and longitudinally passes through the hanger frame 2, thereby achieving the stability of the clamping connection between the keel body 1 and the positioning pad 61.

[0037] The positioning groove 11 is opened at the lower end of the keel body 1, and the positioning column 62 is a cylindrical structure as a whole. The lower end of the positioning column 62 is fixed to the hanger frame 2 and vertically penetrates the positioning pad 61. The positioning pad 61 is made of silicone material and has damping friction, which further improves the damping and anti-slip properties of the keel body 1 suspended from the positioning pad 61.

[0038] Working method: During installation, first fix the expansion screw 21 on the top wall of the house through the preset expansion screw, then suspend the keel body 1 through the preset crane (existing technology), then hang the suspended keel body 1 on the hanger frame 2 through the preset crane, and ensure that the lower end of the keel body 1 is stuck in the positioning pad 61 on the embedded groove 6, then pull the pin pull ring 52 downward to drive the sliding pin 51 to slide down into the preset sliding hole of the fixing block 5. At this time, the spring 53 is stretched and deformed, and then the limit plate 41 is pushed to the left, driving the installation pressure rod 4 to move horizontally along the damping slide 7 Slide to the left, and the pressure rod 4 to be installed passes horizontally through the horizontal through-hole 3, while ensuring that the engaging groove 42 is vertically aligned with the sliding locking pin 51, stop pushing the limit plate 41, and then loosen the pin pull ring 52, the spring 53 pulls back and drives the sliding locking pin 51 to quickly engage in the engaging groove 42 upward, realizing rapid engaging and positioning of the installation pressure rod 4. At the same time, the installation pressure rod 4 also stably presses the upper end surface of the keel body 1, completing convenient hanging and installation, realizing convenient hanging, engaging and limiting installation between the keel body 1 and the hanger frame 2, and improving the convenience of hanging and installing the keel body 1 and the hanger frame 2 on the light steel keel for suspended ceilings.

[0039] In addition, when the keel body 1 is suspended by a preset crane and clamped into the positioning pad 61 on the embedded groove 6, the positioning groove 11 at the lower end of the keel body 1 will be stably clamped and positioned with the positioning column 62, avoiding the longitudinal sliding displacement of the keel body 1 in the hanger frame 2 during the later sliding installation of the pressure rod 4 and the sliding pin 51, further improving the positioning and anti-sliding displacement of the keel body 1 and the hanger frame 2 during the hanging installation process.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
