Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and in particular relates to a detachable hook device for parapet walls. Background Technology

[0002] With the rapid development of urban construction in China, the number of high-rise buildings is increasing daily. In pursuit of more aesthetically pleasing building facades, roof curtain wall designs and lines are becoming more prevalent, with some curtain wall designs even located quite high above the roof. Since these decorative components, including designs and lines, are situated at the highest point of the building, how to safely, efficiently, and economically hoist and install curtain wall materials has become a prominent challenge in traditional curtain wall construction.

[0003] Traditional construction methods typically employ the following approaches:

[0004] 1. Using structural tower cranes to lift materials required for curtain wall and roof construction. While this method is convenient and ensures construction safety, the cost of curtain wall construction increases significantly because it usually takes place after the structure is topped out, requiring the continued rental of structural tower cranes for separate curtain wall construction.

[0005] 2. The sliding rail construction process is used for lifting materials required for curtain wall and roof structure construction. Compared to tower cranes, the sliding rail method is less expensive; however, the installation of the sliding rail system involves the installation of a complete system including winches, guide rails, supports, and electric lifting devices. Due to the complex structure of the sliding rail system and the need for installation at the highest point of the roof, there are inherent safety risks during its construction. Ensuring the reliability of each node in the sliding rail system is also a pressing issue that needs to be addressed.

[0006] 3. A prefabricated, mobile mini crane is used for lifting materials required during the construction of the curtain wall and roof structures. This device is a prefabricated assembly, approximately 2 meters high, and utilizes a lever principle requiring a counterweight for lifting relatively light materials. Equipped with wheels at the bottom, it can be moved on flat ground, making construction convenient and cost-effective. However, its disadvantages include limited construction height; it cannot be used for curtain wall structures exceeding 2 meters above the roof, or when the parapet wall is excessively high.

[0007] Therefore, there is an urgent need for a parapet wall hook device that is simple in structure, easy to construct, improves construction efficiency, is low in cost, easy to assemble, and reusable. Summary of the Invention

[0008] To solve the above problems, the technical solution adopted by the present invention is: a detachable hook device for parapet walls, comprising: a hanger body, a fixing structure, and a hook structure;

[0009] The main body of the hanger is installed on the parapet wall.

[0010] The fixing structure is provided on the main body of the hanger and the parapet wall;

[0011] The hook structure is fitted onto the fixed structure.

[0012] A further improvement is that the main body of the hanger includes two hanger structures, which are respectively set on both sides of the parapet wall.

[0013] A further improvement is made so that both the fixing structure and the hanger structure are made of square steel.

[0014] A further improvement includes a stabilizing structure that fixes the main body of the hanger to the parapet wall.

[0015] A further improvement is made to the fixing structure, which includes: a threaded tube penetrating the parapet wall, gaskets fitted at both ends of the threaded tube, and nuts disposed on the outside of the gaskets, the nuts being tightened onto the threaded tube.

[0016] A further improvement is made to the fixing structure, which includes two bolts that tighten the main body of the hanger into the pre-set bolt holes of the parapet wall.

[0017] A further improvement is made to the hook structure being a sealed U-shaped structure.

[0018] A further improvement is made to the hook structure being a sealed U-shaped square steel.

[0019] A further improvement includes a support structure, one end of which is connected to the main body of the hanger, and the other end of which is connected to the fixed structure.

[0020] A further improvement is that a fixing plate is provided at the bottom of the fixing structure, and the bolts connect the fixing plate to the parapet wall.

[0021] The beneficial effects of the invention are:

[0022] The detachable hook device for parapet walls of this invention is simple to manufacture and easy to install. The main body of the hanger is formed by welding square steel and other materials, and it is securely installed on the parapet wall using various fixing structures. The hook structure with a U-shaped closure is used to connect lifting equipment. The device itself can be disassembled and reused, solving the problems of high construction costs, cumbersome construction methods, and low safety associated with traditional roof curtain wall lines and shapes. It improves construction efficiency, saves on material and machinery rental costs, and features convenient construction, resource conservation, reusability, and lower cost.

[0031] like Figure 1 , Figure 2 As shown, a detachable hook device for a parapet wall 4 includes a hanger body 1, a fixing structure 2, and a mounting bracket 1. Figure 3The hook structure 3 is shown; the main body 1 of the hanger is set on the parapet wall 4; the fixing structure 2 is set on the main body 1 of the hanger and the parapet wall 4, and is used to firmly fix the main body 1 of the hanger to the parapet wall 4; the hook structure 3 is fitted onto the fixing structure 2, and is used to connect the lifting equipment to lift the curtain wall material. The detachable hook device for the parapet wall of the present invention is simple to manufacture and easy to construct. The main body of the hanger is formed by welding materials such as square steel, and is firmly installed on the parapet wall with various fixing structures. The hook structure is set to connect the lifting equipment. The device itself can be disassembled and reused, which solves the problems of high construction cost, cumbersome construction method and low safety of traditional roof curtain wall lines and shapes, improves construction efficiency, saves material and machinery rental costs, and has the characteristics of convenient construction, resource saving, reusability and lower cost.

[0032] The main body of the hanger 1 includes two hanger structures, which are respectively set on both sides of the parapet wall 4. Through the joint action of the hanger structures on both sides, the main body of the hanger 1 is reliably installed on the parapet wall 4.

[0033] Both the fixed structure 2 and the hanger structure are made of square steel. Specifically, the hanger structure can be welded from 70×70×5mm square tubing, and the steel used for the square tubing should be no less than Q235 steel to ensure that the main body of the hanger 1 has sufficient structural strength and load-bearing capacity. The width of the main body of the hanger 1 can be set according to the width of the structural beam, and the length is the width of the parapet wall 4 plus 470mm, with a width of 70mm and a height of 670mm. The length of the cantilever beam at the top of the hanger is 400mm.

[0034] This device also includes a stabilizing structure 5, which fixes the main body 1 of the hanger to the parapet wall 4 to prevent the main body 1 of the hanger from sliding along the beam direction or undergoing other unstable displacements. The stabilizing structure 5 can be fixed to the structure using 2×M16 expansion bolts, which horizontally fix the main body 1 of the hanger to the structural beam to ensure the stability of the overall structure.

[0035] The stabilizing structure 5 includes a threaded pipe 6 penetrating the parapet wall 4, washers 7 fitted at both ends of the threaded pipe 6, and nuts 8 located on the outside of the washers 7. The nuts 8 are tightened onto the threaded pipe 6. In practice, holes can be drilled or pre-drilled in the parapet wall 4, and M14 tie bolts can be used as threaded pipe 6, which are then fixed in conjunction with the washers 7 and double nuts 8. That is, the hanger is fixed to the parapet wall 4 by the M14 tie bolts. The use of double nuts 8 can effectively prevent loosening and enhance the reliability of the connection. Alternatively, two bolts can be directly fixed into the pre-drilled bolt holes, which is simple to operate and provides a stable connection.

[0036] The hook structure 3 is a closed U-shaped structure. Specifically, the hook structure 3 is a closed U-shaped square steel, also known as a lifting ring. The lifting ring can be made of... It is made of 20 steel bars and welded to the top cantilever beam or other suitable positions of the main body 1 of the hanger for reliable connection of lifting equipment such as hand chain hoists.

[0037] This device also includes a support structure 9, one end of which is connected to the main body 1 of the hanger, and the other end is connected to the fixed structure 2. Preferably, the angle between the support structure 9 and the fixed structure 2 is 60°. The support structure 9 can provide auxiliary support and reinforcement for the connection between the fixed structure 2 and the main body 1 of the hanger, further improving the load-bearing capacity and stability of the overall structure. For example, a square steel tube of appropriate specifications can be used as the support structure 9, which is welded or bolted between the main body 1 of the hanger and the fixed structure 2.

[0038] A fixing plate 10 is installed at the bottom of the fixing structure 2, and bolts 11 connect the fixing plate 10 to the parapet wall 4. By setting the fixing plate 10, the contact area between the fixing structure 2 and the parapet wall 4 is increased, making the fixing effect of the bolts more uniform and reliable, and further improving the installation stability of the fixing structure 2.

[0039] When using the detachable hook device for the parapet wall 4, the first step is to check whether the structural beam at the location of the fixed hanger device has reached the design strength. Then, the position on the beam where the material to be lifted needs to be laid out. Next, holes are drilled for the fixing bolts and expansion bolts are placed. Holes are drilled or sleeve holes are pre-drilled in the parapet wall 4. The hanger device is then clamped onto the beam and fixed with M14 tie bolts, and finally secured at the top with expansion bolts. After the hanger device is fixed to the structure, one end of a hand-operated hoist is connected to the hook structure 3 (lifting ring) at the top, and the other end is connected to the material to be lifted. Lifting is then performed. The operator of the hand-operated hoist can be located inside or outside the suspended basket on the roof. This device has a load limit of 300 kg for the lifted components and materials to ensure construction safety.

[0040] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
