Description

Technical Field

[0001] This utility model relates to the field of pre-embedded fixing sleeve technology, specifically to a non-welded pre-embedded fixing sleeve fixing device for aluminum formwork beams. Background Technology

[0002] In the construction industry, more and more real estate projects are being delivered fully furnished. Compared with traditional construction projects, fully furnished projects have a large number of pre-embedded points for fire protection pipes, water supply and drainage pipes, ventilation pipes, gas pipes, and electrical conduits. The pre-embedding accuracy of these pipe points is also very high. If the pre-embedded position deviates, it will affect the subsequent decoration construction. Therefore, controlling the accuracy of the pre-embedded pipe points is a major problem that urgently needs to be solved in the main construction stage.

[0003] Traditional methods of pre-embedded sleeve positioning involve fixing the sleeve to the reinforcing bars during the rebar tying process using tying wires or welding positioning bars. However, when the sleeve is fixed by tying wires, the reinforcing bars are prone to swaying during formwork erection, and the pre-embedded sleeve will also deviate from its intended position. Therefore, this application is hereby submitted. Utility Model Content

[0004] This application proposes a non-welded pre-embedded fixing sleeve fixing device for aluminum formwork beams to solve the technical problem in the prior art where, during the rebar tying process, the sleeve is fixed to the rebar by means of tying wire or welding positioning bars. When the sleeve is fixed by tying wire, the rebar is prone to shaking during formwork erection, and the pre-embedded sleeve will also deviate along with the rebar. The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A non-welded pre-embedded fixing sleeve fixing device for aluminum formwork beams includes an aluminum formwork, a hole, a sleeve, and a pre-embedded fixing device. The hole is formed on the aluminum formwork, and the pre-embedded fixing device is located inside the sleeve. The pre-embedded fixing device and the sleeve are arranged between the hole in the aluminum formwork. The pre-embedded fixing device includes a fixing head, a pin, a first telescopic tube, a second telescopic tube, a spring, and a piston head. The first telescopic tube and the second telescopic tube are slidably connected. The fixing head is respectively located at the ends of the first telescopic tube and the second telescopic tube. The spring is arranged between the two fixing heads and is sleeved on the first telescopic tube and the second telescopic tube. The pin is respectively located at the center position of the two fixing heads and is connected to the hole.

[0006] Furthermore, each of the fixed heads is equipped with a piston head.

[0007] Furthermore, the piston head is interference-fitted with the sleeve.

[0008] Furthermore, the piston head is a rubber piston head.

[0009] Furthermore, the diameter of the pin is 12-15mm.

[0010] Furthermore, the diameter of the hole is 14-17 mm.

[0011] Compared with the prior art, the beneficial effects of this utility model include:

[0012] Based on the diameter and length of the pre-embedded sleeve, this application pre-fabricates the pre-embedded fixing device, inserts the pre-embedded fixing device into the sleeve, and after the sleeve is installed in the pre-embedded position, squeezes the sleeve and the pre-embedded fixing device into the aluminum template, so that the shaft pin is inserted into the hole in the aluminum template to fix the sleeve. This reduces the binding or welding positioning process, greatly improves the efficiency of sleeve pre-embedding, saves labor costs, and the pre-embedded fixing device can be reused multiple times. After the template is removed, the pre-embedded fixing device can automatically pop out, which can reduce construction costs. Attached Figure Description

[0020] Please see the appendix Figure 1-3 A non-welded pre-embedded fixing sleeve fixing device for aluminum formwork beams includes an aluminum formwork 1, a hole 2, a sleeve 3, and a pre-embedded fixing device. The hole 2 is opened on the aluminum formwork 1, and the diameter of the hole 2 is 14-17mm. The pre-embedded fixing device is located inside the sleeve 3, and the pre-embedded fixing device and the sleeve 3 are arranged between the hole 2 of the aluminum formwork 1. The pre-embedded fixing device includes a fixing head 4, a pin 5, a first telescopic tube 6, a second telescopic tube 7, a spring 8, and a piston head 9. The first telescopic tube 6 and the second telescopic tube 7 are slidably connected. The fixing head 4 is respectively located at the ends of the first telescopic tube 6 and the second telescopic tube 7. The spring 8 is arranged between the two fixing heads 4 and is sleeved on the first telescopic tube 6 and the second telescopic tube 7. The pin 5 is respectively located at the center position of the two fixing heads 4 and is connected to the hole 2. The diameter of the pin 5 is 12-15mm.

[0021] In this embodiment, the non-welded pre-embedded fixing sleeve 3 fixing device for the aluminum formwork beam mainly consists of aluminum formwork 1, holes 2, sleeve 3, and pre-embedded fixing devices. The aluminum formwork 1 serves as the foundation of the building formwork, and the holes 2 on it are used to install the pre-embedded fixing devices and sleeve 3. The pre-embedded fixing devices are the core components of the device. They are located inside the sleeve 3 and achieve a fixing effect by cooperating with the holes 2 on the aluminum formwork 1.

[0022] Installation Preparation: First, drill holes 2 of the appropriate diameter on the aluminum template 1 according to the design requirements. Then, insert the sleeve 3 into the hole 2, ensuring that the sleeve 3 fits tightly against the wall of the hole 2. The pre-embedded fixing device consists of a fixing head 4, a shaft pin 5, a first telescopic tube 6, a second telescopic tube 7, a spring 8, and a piston head 9. Place the entire pre-embedded fixing device into the sleeve 3. At this time, the first telescopic tube 6 and the second telescopic tube 7 maintain a certain degree of expansion and contraction under the action of the spring 8. After the pre-embedded fixing device is fully inserted into the sleeve 3, it is initially fixed by the cooperation of the shaft pin 5 and the hole 2. At this time, the position of the pre-embedded fixing device can be finely adjusted by adjusting the expansion and contraction lengths of the first telescopic tube 6 and the second telescopic tube 7 according to actual needs, ensuring that it fits tightly against the aluminum template 1. After adjustment, the elasticity of the spring 8 will maintain the stable position of the pre-embedded fixing device in the sleeve 3. At the same time, the tight cooperation between the shaft pin 5 and the hole 2 further enhances the stability of the fixing.

[0023] Pre-installed fixing devices are customized according to the diameter and length of sleeve 3. The corresponding model of the pre-installed fixing device is inserted into the sleeve 3. After the formwork is installed, a hole 2 is drilled at the pre-installation position of sleeve 3. The diameter of hole 2 is generally 16mm (2mm larger than the diameter of pin 5). Then, the beam and slab reinforcement is fabricated. During or after the reinforcement construction, under the force of spring 8, sleeve 3 and the pre-installed fixing device are installed at the pre-installation position. Pin 5 is inserted into the aluminum formwork 1 with the pre-drilled hole 2. After checking that the installation is secure, concrete pouring can proceed. After the concrete is poured and the formwork removal conditions are met, the beam side formwork can be removed. The pre-installed fixing device will automatically pop out during formwork removal; there is no need to use brute force to remove it and damage the concrete edges. Simply remove the pre-installed fixing device. Then, the pre-installed fixing devices are stored according to their model for use in the pre-installation construction of sleeve 3 in the next layer of beams.

[0024] In some embodiments, each fixing head 4 is provided with a piston head 9, which is interference-fitted with the sleeve 3. The piston head 9 is a rubber piston head 9. This enhances the sealing and stability between the embedded fixing device and the sleeve 3. The rubber material has good elasticity and sealing performance, and can closely fit the inner wall of the sleeve 3, ensuring that mortar does not enter the interior of the embedded fixing device during concrete pouring.
