Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, specifically to a tool suitable for hoisting assembly type composite floor. BACKGROUND

[0002] With the acceleration of urbanization, the construction industry is facing unprecedented challenges and opportunities. In today's pursuit of efficiency, energy saving and environmental protection, assembly type composite floor as a kind of modern building components, because of its standardization production, rapid installation and good structure performance, has been widely used in modern buildings. This floor is usually composed of prefabricated concrete layer and steel bar truss components, which not only ensures the stability of the structure, but also improves the construction efficiency;

[0003] However, in the hoisting process of assembly type composite floor, the traditional method often relies on the hook of tower crane and steel wire rope for direct hoisting. Although this method meets the basic needs of hoisting to some extent, its inherent limitations are increasingly highlighted. Specifically, due to the large volume, heavy weight and flat shape of the composite floor, when hoisted directly with hook and steel wire rope, the attitude control of the floor in the air becomes particularly difficult. Under the influence of wind, operation error and other factors, the floor is easy to shake, which not only increases the construction difficulty, but more importantly, brings great safety hazards to the on-site construction personnel and equipment, therefore we propose a tool suitable for hoisting assembly type composite floor to solve the above problems.

[0013] Further, the specification of the first steel wire rope is M12, and the specification of the second steel wire rope is M14.

[0014] (Three) beneficial effects

[0015] Compared with the prior art, the tool suitable for hoisting assembly type composite floor has the following beneficial effects:

[0016] When the tower crane starts hoisting, the lifting hook lifts the whole hoisting tool through the first steel wire rope and the first universal lifting lug. Since the first steel wire rope is locked together by the padlock and is stably connected with the upper square steel pipe, the stability and safety during hoisting can be ensured. The second steel wire rope forms a stable triangular hoisting system through the fixed lifting lug, the fixed pulley and the second universal lifting lug, further enhancing the load-bearing capacity and stability of the whole hoisting tool. During hoisting, the weight of the composite floor body is evenly distributed to the whole hoisting tool through the second universal lifting lug and the fixed pulley, thereby avoiding damage or safety accidents caused by excessive stress on a single point. In addition, since the first universal lifting lug and the second universal lifting lug have the universal adjusting function, they can adapt to the hoisting requirements of different angles and directions, improving the hoisting efficiency and flexibility.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figures 1-4The utility model discloses a kind of tools suitable for hoisting assembly type composite floor shown in an embodiment of the utility model, including horizontal steel pipe 1, two second steel wire ropes 11 and composite floor body 9, two horizontal steel pipe 1 are equipped, multiple square steel pipes 2 are fixedly connected between two horizontal steel pipe 1, the top of horizontal steel pipe 1 is equipped with two first universal lifting lug 3, first universal lifting lug 3 is equipped with first steel wire rope 4, the top of first steel wire rope 4 is equipped with lifting hook 5, four first steel wire ropes 4 are hooked together with lifting hook 5 by lock catch, the bottom of two square steel pipes 2 in four square steel pipes 2 is welded with two connecting pipes 6, the end of connecting pipe 6 is welded with fixed lifting lug 7, the bottom of other two square steel pipes 2 in four square steel pipes 2 is rotatably connected with two fixed pulleys 8, and the top of composite floor body 9 is movably contacted with multiple second universal lifting lug 10, second steel wire rope 11 passes through fixed lifting lug 7, second universal lifting lug 10, fixed pulley 8 in turn and with an fixed lifting lug 7 fixed, form stable triangle structure, when tower crane starts to hoist, lifting hook 5 is lifted by first steel wire rope 4 and first universal lifting lug 3, since first steel wire rope 4 has been locked together by lock catch, and is connected with upper square steel pipe 2 firm, thus can ensure stability and safety in hoisting process, second steel wire rope 11 forms a stable triangle hoisting system through fixed lifting lug 7, fixed pulley 8 and second universal lifting lug 10, further enhances the load capacity and stability of entire hoisting tool, in hoisting process, the weight of composite floor body 9 is evenly distributed to entire hoisting tool through second universal lifting lug 10 and fixed pulley 8, to avoid damage or safety accident caused by single-point force too large, and simultaneously, since first universal lifting lug 3 and second universal lifting lug 10 have universal adjusting function, thus can adapt to hoisting demand of different angles and directions, improve hoisting efficiency and flexibility.

[0025] In some embodiments, two sides of the second universal lifting lug 10 are welded with a connecting block 12, the connecting block 12 is threadedly connected with the composite floor body 9 by a bolt 13, and the connecting block 12 is provided to play a connecting role.

[0026] In some embodiments, the fixed pulley 8 is made of high-strength aluminum alloy material, and the static tension of the fixed pulley 8 is 3T. The high-strength aluminum alloy has the characteristics of light weight and high strength. Its density is relatively small, but its strength is much higher than that of ordinary aluminum alloy. This makes the fixed pulley 8 significantly reduce the weight while ensuring sufficient strength, thereby reducing the dead weight of the entire hoisting tool and improving the hoisting efficiency. The fixed pulley 8 has a static tension of 3T, which means it can withstand a pulling force of up to 3 tons without being damaged.

[0027] In some embodiments, the bolt 13 is made of alloy steel material, which has high strength and hardness, and thus has good fatigue resistance. In the case of hoisting and assembling the composite floor and other places that need to bear dynamic load frequently, the alloy steel bolt 13 can maintain stable connection performance for a long time, reducing the risk of fracture caused by fatigue.

[0028] In some embodiments, the square steel pipe 2 has a cross-sectional size of 200mm x 200mm x 8.00mm. The cross-sectional size of 200mm x 200mm provides a larger stress area, and the wall thickness of 8.00mm makes the square steel pipe 2 have higher bending and torsional strength. When bearing transverse load and torque, the square steel pipe 2 of this specification performs well, effectively enhancing the overall stability of the building structure and reducing the risk of deformation.

[0029] In some embodiments, the first steel wire rope 4 has a specification of M12, and the second steel wire rope 11 has a specification of M14. By selecting the first steel wire rope 4 with a specification of M12 and the second steel wire rope 11 with a specification of M14, the carrying capacity and safety during hoisting and assembling the composite floor can be ensured, while the maintenance cost is reduced and the work efficiency is improved.

[0030] The working principle or structural principle is that when the tower crane starts hoisting, the hook 5 lifts the entire hoisting tool through the first steel wire rope 4 and the first universal lug 3. Since the first steel wire rope 4 has been locked together by the lock and is connected stably with the upper square steel pipe 2, the stability and safety during hoisting can be ensured. The second steel wire rope 11 forms a stable triangular hoisting system through the fixed lug 7, the fixed pulley 8 and the second universal lug 10, further enhancing the carrying capacity and stability of the entire hoisting tool. During hoisting, the weight of the composite floor body 9 is evenly distributed to the entire hoisting tool through the second universal lug 10 and the fixed pulley 8, thereby avoiding damage or safety accidents caused by excessive stress on a single point. At the same time, since the first universal lug 3 and the second universal lug 10 have universal adjustment function, they can adapt to hoisting requirements of different angles and directions, improving the hoisting efficiency and flexibility.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
