Description

Technical Field

[0001] The invention belongs to the technical field of hoisting walls, and particularly relates to a combined hoisting wall and an installation method. Background Art

[0002] The hoisting wall is composed of two words, hoisting and wall. Hoisting generally refers to the installation and positioning of equipment by a crane or a hoisting mechanism. During the overhaul or repair process, various hoisting tools are used to change the position of equipment, workpieces, etc. The wall is mainly a barrier for construction. A precast slab is a type of wall. The hoisting wall refers to the steps of installing the wall during the installation process.

[0003] Traditional hoisting walls do not have a combined function. When constructing precast wall panels and hoisting the boards, they are hoisted one by one, which wastes time, reduces work efficiency, and is not conducive to large-scale operations. Traditional steel beams and channel steels do not have a supporting function and are usually used separately. When not in use, it is easy to cause the loss of steel beams and channel steels. And during the matching process, there is no function of cleaning and oiling the channel steels for maintenance. If the channel steels are not maintained in time after long-term use, the service life of the channel steels will be reduced. When traditional hoisting walls hoist precast slabs, they usually fix the precast slabs with screws or bolts. Such a hoisting method is not stable, easily causes the precast slabs to slip during hoisting, has a certain danger, and is easy to damage the precast slabs. Summary of the Invention

Traditional steel beams and channel steels do not have a supporting function and are usually used separately. When not in use, it is easy to cause the loss of steel beams and channel steels. And during the matching process, there is no function of cleaning and oiling the channel steels for maintenance. If the channel steels are not maintained in time after long-term use, the service life of the channel steels will be reduced.

[0023] The present invention also discloses a method for installing a combined hoisting wall, which specifically includes the following steps:

[0024] S1. Connection of precast slabs. Place the channel steel between the first precast slab and the second precast slab. Rotate the positioning bolt. The positioning bolt rotates and descends inside the threaded nut and rotates into the second precast slab, thereby realizing the fixation of the second precast slab. When it is necessary to disassemble the second precast slab, when the positioning bolt is turned out of the threaded nut, due to the elastic force of the second spring, the positioning bolt pops out, eliminating the need for manual removal. Moreover, the fixing sleeve has a certain limiting and fixing effect on the positioning bolt to prevent the positioning bolt from falling when not in use.

[0025] S2. Hoisting of the precast slab. Due to the elastic force of the third spring, the side block moves and is inserted into the positioning cavity. Then, pull the bolt pin. The movement of the bolt pin drives the contraction of the fourth spring and drives the bolt pin to be inserted into the inner part of the collar, thus further fixing the second precast slab;

[0026] S3. Matching and storage of the channel steel and the steel beam. When the wall panel does not need to be hoisted, place the channel steel inside the steel beam and rotate the cover plate. Due to the elastic forces of the telescopic rod and the first spring, the top block at one end of the telescopic rod is embedded inside the convex block to achieve the storage of the channel steel. Then, move the extension shaft. The movement of the moving shaft drives the cleaning brush to slide on the outer surface of the channel steel, thus cleaning the outer surface of the channel steel. After cleaning, press the moving shaft to move, driving the piston plate to move, and squeezing the antirust oil into the cleaning brush, thus performing antirust treatment on the channel steel.

[0027] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are:

[0028] 1. In the present invention, by installing a steel beam, a channel steel, a first precast slab, a second precast slab and a towing cable, rotate the positioning bolt. The positioning bolt rotates and descends inside the threaded nut and rotates into the second precast slab, thus fixing the second precast slab. When the second precast slab needs to be disassembled, when the positioning bolt is turned out from the threaded nut, due to the elastic force of the second spring, the positioning bolt pops out without the need for manual removal. And the fixing sleeve has a certain limit fixation on the positioning bolt to prevent the positioning bolt from falling when not in use, solving the problem that the traditional hoisting wall does not have a combined function. When constructing and hoisting the precast wall panel, it is hoisted one by one, wasting time, reducing work efficiency and being not conducive to large-area operation. It is more practical and has a higher work efficiency.

[0029] 2. In the present invention, by installing a third spring, a side block and a positioning cavity, when the first precast slab and the second precast slab need to be hoisted, due to the elastic force of the third spring, the side block moves and is inserted into the positioning cavity. Then, pull the bolt pin. The movement of the bolt pin drives the contraction of the fourth spring and drives the bolt pin to be inserted into the inner part of the collar, thus further fixing the second precast slab. This solves the problem that when the traditional hoisting wall hoists the precast slab, it usually fixes the precast slab by screws or bolts. Such a hoisting method is not stable, easily causes the precast slab to slide during hoisting, has a certain danger, and is easy to damage the precast slab. It is convenient for assembly and disassembly and is more convenient during hoisting;

[0030] 3. In the present invention, with the side shell, the fifth spring and the cleaning brush installed, when the wall panel does not need to be hoisted, the channel steel is placed inside the steel beam, and the cover plate is rotated. Due to the elastic force of the telescopic rod and the first spring, the top block at one end of the telescopic rod is embedded inside the convex block to achieve the storage of the channel steel. Then, the moving shaft is moved. The movement of the moving shaft drives the cleaning brush to slide on the outer surface of the channel steel, thereby realizing the cleaning of the outer surface of the channel steel. After the cleaning is completed, the moving shaft is pressed to move, driving the piston plate to move, and squeezing the antirust oil into the cleaning brush, thereby realizing the antirust treatment of the channel steel. This solves the problem that the traditional steel beam and channel steel do not have the function of supporting use, and they are usually used separately. When not in use, it is easy to cause the loss of the steel beam and channel steel, and there is no function of cleaning and oiling maintenance for the channel steel during the matching process. If the channel steel is not maintained in time after long-term use, the service life of the channel steel is extended. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the fourth spring (28) is fixedly connected to the outer surface of the bolt (27), and the other end of the fourth spring (28) is fixedly connected to the inner wall of the second mounting shell (29). Two second mounting shells (29) are symmetrically installed about the longitudinal center axis of the collar (26).

5. A combined hoisting wall according to claim 4, wherein, a second cleaning cotton (37) is arranged on the inner wall of the steel beam (11). The upper surface of the second cleaning cotton (37) contacts and presses against the lower surface of the channel steel (6). A side shell (4) is fixedly installed on the side wall of the steel beam (11).

6. A combined hoisting wall according to claim 5, wherein, a piston plate (39) is slidably installed on the inner wall of the side shell (4). An extension shaft (3) is inserted and installed inside the side shell (4). One end of the extension shaft (3) is fixedly connected to the side wall of the piston plate (39). A fifth spring (34) is sleeved on the outer surface of the extension shaft (3). One end of the fifth spring (34) is fixedly connected to the outer surface of the extension shaft (3), and the other end of the fifth spring (34) is fixedly connected to the outer surface of the side shell (4).

7. A method for installing a combined hoisting wall according to claim 6, wherein, specifically includes the following steps: S1. Connection of precast slabs: Place the channel steel (6) between the first precast slab (5) and the second precast slab (8). Rotate the positioning bolt (7). The positioning bolt (7) rotates and descends inside the threaded cap (19) and rotates into the second precast slab (8), thus fixing the second precast slab (8). When it is necessary to disassemble the second precast slab (8), when the positioning bolt (7) is removed from the threaded cap (19), due to the elastic force of the second spring (14), the positioning bolt (7) is ejected without the need for manual removal. And the fixing sleeve (17) has a certain limit and fixation on the positioning bolt (7) to prevent the positioning bolt (7) from falling when not in use. S2. Hoisting of precast slabs: Due to the elastic force of the third spring (23), the side block (21) moves and is inserted into the positioning cavity (22). Then pull the bolt (27). The movement of the bolt drives the fourth spring (28) to contract and drives the bolt (27) to be inserted into the inner ring sleeve (26), thus further fixing the second precast slab (8). S3. Cooperation and storage of the channel steel (6) and the steel beam (11): When the wall panel does not need to be hoisted, place the channel steel (6) inside the steel beam (11). Rotate the cover plate (33). Due to the elastic force of the telescopic rod (32) and the first spring (10), the top block (9) at one end of the telescopic rod (32) is embedded in the convex block (36) to achieve the storage of the channel steel (6). Then move the moving shaft (13). The movement of the moving shaft (13) drives the cleaning brush (38) to slide on the outer surface of the channel steel (6), thus cleaning the outer surface of the channel steel (6). After cleaning, press the extension shaft (3) to move, driving the piston plate (39) to move, and squeezing the antirust oil into the cleaning brush to achieve the antirust treatment of the channel steel (6).
