Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a formwork hoisting device for building construction. Background Technology

[0002] Construction formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components into specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete projects, accelerate construction progress, and reduce project costs.

[0003] Common building formwork includes steel formwork and wooden formwork. Since it is not easy to fix the hoisting structure on the surface of wooden formwork, cloth straps are usually used to bind the wooden formwork during hoisting. However, the binding process is relatively complicated. If the binding is not secure, it is easy to fall off when it swings in the air after being hoisted, which poses a great safety hazard. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a formwork hoisting device for building construction.

[0005] The technical solution of this utility model to achieve the above objectives is a formwork hoisting device for building construction, comprising:

[0006] The boss-type base is placed on the ground. It consists of a square tube frame and a panel. The panel is welded to the upper surface of the square tube frame. A hinge shaft is set on both sides of the center of the front and rear surfaces of the boss.

[0007] The hinged sleeve has its lower end movably hinged to the hinge shaft and slides in contact with the boss side surface of the boss-type base.

[0008] A rectangular hoisting frame is movably placed on a boss-type base and movably fitted onto the boss of the boss-type base, with hoisting lugs installed at the four corners of its upper surface;

[0009] The positioning boss is located at the center of the front and rear surfaces inside the annular square lifting frame. Adjusting slide rods are installed at both ends of the boss. One end of the adjusting slide rod is fixedly connected to the annular square lifting frame, and a compression spring is installed at the other end. The compression spring is fitted onto the adjusting slide rod.

[0010] The adjusting slider is fitted onto the adjusting slide rod and slides in contact with the inner surface of the annular square hoisting frame. A hinge shaft is provided on one side of the frame.

[0011] The hinged telescopic rod has its lower end slidably inserted into the hinged sleeve, its upper end movably hinged to the hinge shaft, and its lower end is equipped with a limiting slide pin, which is located inside the hinged sleeve and slidably connected to the hinged sleeve.

[0012] The positioning slide rod is installed on both sides of the center of both ends of the boss-type base, and is located outside the boss of the boss-type base. It is slidably inserted into the ring square lifting frame, and a limit stop is installed at its upper end.

[0013] In this utility model, when the annular square hoisting frame is placed on the boss-type base, its upper surface is flush with the upper surface of the boss of the boss-type base.

[0014] In this utility model, when the annular square lifting frame is placed on the boss-type base, the hinged telescopic rod and the hinged sleeve are housed in the gap between the annular square lifting frame and the boss-type base.

[0015] In this utility model, when the annular square hoisting frame is hoisted up by external hoisting equipment, the hinged telescopic rod extends out from the hinged sleeve and is adjusted at the corresponding angle to make the annular square hoisting frame rise vertically.

[0016] In this utility model, when the annular square hoisting frame rises to below the limiting block, the limiting sliding column rises to the uppermost end inside the hinged sleeve.

[0017] In this invention, when the annular square hoisting frame rises below the limiting block, the adjusting slider contacts the compression spring and squeezes the compression spring, so that the compression spring is in a compressed state.

[0018] In this invention, the lifting lugs are located outside the limiting block and are symmetrically distributed along the center line of the annular square lifting frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By placing the ring-shaped square lifting frame on the boss-type base, the building formwork can be quickly stacked on the boss of the boss-type base, which facilitates the loading and unloading of the building formwork and makes it more convenient to use.

[0021] 2. The ring-shaped hoisting frame is hoisted by external hoisting equipment, which gradually raises it and drives the hinged sleeve to rotate. The hinged sleeve and the positioning slide rod limit the building formwork on the boss-type base. On the one hand, the building formwork can be hoisted without being tied, reducing the workload of the workers. On the other hand, it can prevent the building formwork from falling due to shaking during the hoisting process, thus improving the safety of building formwork hoisting.

[0022] 3. By utilizing the limiting contact of multiple limit blocks and limit sliding columns, the connection between the annular square hoisting frame and the boss-type base is made more stable, thereby ensuring the uniformity of force on the boss-type base during hoisting and ensuring the stability of the building formwork hoisting.

[0028] 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.

[0029] This utility model provides a technical solution, such as Figures 1-3 As shown; a construction formwork hoisting device includes: a boss-type base 1, placed on the ground, which is composed of a square tube frame 11 and a panel 12. The panel 12 is welded to the upper surface of the square tube frame 11, and hinge shafts 13 are provided on both sides of the center of the front and rear surfaces of the boss; a hinge sleeve 2, the lower end of which is movably hinged to the hinge shafts 13 and slides in contact with the boss side surface of the boss-type base 1.

[0030] In this embodiment of the utility model, by utilizing the shape of the boss-type base 1, the annular square lifting frame 3 can be lowered above it, thereby making the upper surface of the boss-type base 1 flush with the upper surface of the annular square lifting frame 3. Workers can use manual labor or forklifts to quickly move the building template onto the boss-type base 1, so that the building template can be quickly loaded and unloaded, making it convenient for workers to use.

[0031] In this embodiment of the utility model, the boss-type base 1 composed of the square tube frame 11 and the panel 12 can utilize the strength of the square tube frame 1 to ensure the strength of the boss-type base 1, enabling it to stably hoist and transport building templates. The panel 12 can ensure the smoothness and flatness of the upper surface of the boss-type base 1, making the stacking of building templates more stable.

[0032] In this embodiment of the utility model, hinged sleeves 2 are provided on the front and rear sides of the boss of the boss-type base 1, which can be adjusted by angle and stand upright on the front and rear sides of the boss of the boss-type base 1, thereby limiting the building template to prevent it from falling during hoisting.

[0033] A rectangular hoisting frame 3 is movably placed on a boss-type base 1 and movably fitted onto the boss of the boss-type base 1. Hoisting lugs 31 are installed at the four corners of its upper surface. A positioning boss 4 is set at the center of the front and rear surfaces inside the rectangular hoisting frame 3. Adjusting slide rods 41 are installed at both ends of the boss. One end of the adjusting slide rod 41 is fixedly connected to the rectangular hoisting frame 3, and a compression spring 42 is installed at the other end. The compression spring 42 is fitted onto the adjusting slide rod 41. An adjusting slider 5 is slidably fitted onto the adjusting slide rod 41 and slides in contact with the inner surface of the rectangular hoisting frame 3. A second hinge shaft 51 is set on one side surface of the slider. A hinge telescopic rod 6 has its lower end slidably inserted into the hinge sleeve 2. Its upper end is movably hinged to the second hinge shaft 51. A limiting slide post 61 is installed at its lower end. The limiting slide post 61 is located inside the hinge sleeve 2 and is slidably connected to the hinge sleeve 2.

[0034] In this embodiment of the utility model, by utilizing the sliding cooperation between the adjusting slide rod 41 and the adjusting slider 5, the annular square hoisting frame 3 can be lifted under force during hoisting, thereby driving the hinged telescopic rod 6 to extend, and causing the hinged telescopic rod 6 to drive the hinged sleeve 2 to adjust the angle, so that the hinged telescopic rod 6 and the hinged sleeve 2 are gradually adjusted to a vertical state, thereby moving the annular square hoisting frame 3 to the upper side of the building formwork.

[0035] In this embodiment of the utility model, by utilizing the lifting lug 31, the annular square lifting frame 3 can be quickly connected to the lifting equipment using wire ropes and hooks, enabling it to carry out lifting work quickly.

[0036] In this embodiment of the utility model, by using the compression spring 42, when the annular square hoisting frame 3 rises to its highest position, the adjusting slider 5 can squeeze the compression spring 42 to compress it. When the annular square hoisting frame 3 descends, the elasticity of the compression spring 42 can be used to push the hinge telescopic rod 6 to drive the hinge sleeve 2 to adjust the angle, so that the annular square hoisting frame 3 can quickly descend onto the boss-type base 1 by its own weight, so that workers can unload the building formwork.

[0037] The positioning slide rod 7 is installed on both sides of the center of both ends of the boss-type base 1 and is located outside the boss of the boss-type base 1. It is slidably inserted into the annular square lifting frame 3, and a limit stop 71 is installed on its upper end.

[0038] In this embodiment of the utility model, by using the positioning slide bar 7, after the building template is placed on the boss-type base 1, the positioning slide bar 7 and the four-sided limiting of the hinge sleeve 2 can restrict the building template on the boss of the boss-type base 1, thereby effectively ensuring the safety of the building template during the hoisting process and preventing it from falling due to accidents during the hoisting process.

[0039] In this embodiment of the utility model, by using the setting of the limiting block 71, the ring square hoisting frame 3 can be limited by the limiting block 71 during hoisting, so as to drive the boss-type base 1 to rise and fall, so as to facilitate the hoisting work of building formwork.

[0040] In this utility model, when the ring-shaped square hoisting frame 3 is placed on the boss-type base 1, its upper surface is flush with the upper surface of the boss of the boss-type base 1; this makes it convenient for workers to quickly stack building templates onto the boss of the boss-type base 1.

[0041] In this utility model, when the annular square lifting frame 3 is placed on the boss-type base 1, the hinged telescopic rod 6 and the hinged sleeve 2 are stored in the gap between the annular square lifting frame 3 and the boss-type base 1; by hiding the hinged telescopic rod 6 and the hinged sleeve 2, it is avoided that they affect the loading and unloading of the building formwork, making the device more convenient to use.

[0042] In this utility model, when the annular square hoisting frame 3 is hoisted and raised by external hoisting equipment, the hinged telescopic rod 6 extends out from the hinged sleeve 2 and is adjusted at the corresponding angle to make the annular square hoisting frame 3 rise vertically; by using the rise of the annular square hoisting frame 3, the hinged sleeve 2 extends out from the boss-type base 1, thereby limiting the building formwork and ensuring the safety of the building formwork hoisting.

[0043] In this utility model, when the annular square hoisting frame 3 rises below the limiting block 71, the limiting sliding column 61 rises to the uppermost part inside the hinge sleeve 2; so that the boss-type base 1 can be evenly stressed, thereby ensuring the safe use of the device and making the hoisting of building formwork more stable.

[0044] In this invention, when the annular square hoisting frame 3 rises below the limiting block 71, the adjusting slider 5 contacts and squeezes the compression spring 42, causing the compression spring 42 to be in a compressed state. When the annular square hoisting frame 3 descends under its own weight, the compression spring 42 can push the adjusting slider 5 to move, thereby enabling the hinged telescopic rod 6 and the hinged sleeve 2 to automatically adjust their angles so that the annular square hoisting frame 3 can automatically descend onto the boss-type base 1, thus facilitating the unloading of the building formwork.

[0045] In this utility model, the lifting lugs 31 are located outside the limiting block 71 and are symmetrically distributed along the center line of the annular square lifting frame 3; ensuring the stability of the building formwork during lifting.

[0046] When using this utility model, the annular square lifting frame 3 is located on the boss-type base 1, and the hinged telescopic rod 6 and the hinged sleeve 2 are located in the gap between the annular square lifting frame 3 and the boss-type base 1. Workers can use a forklift or manual means to move the building template onto the boss of the boss-type base 1 and stack and align them.

[0047] After the building formwork is placed, the workers connect the hook of the hoisting equipment to the wire rope and install the hooks at both ends of the wire rope onto the hoisting lugs 31. Then they can control the hoisting equipment to carry out the hoisting work.

[0048] As the hoisting equipment lifts the ring-shaped hoisting frame 3, the ring-shaped hoisting frame 3 detaches from the boss-type base 1 and is positioned vertically by the positioning slider 7. At the same time, during the lifting process of the ring-shaped hoisting frame 3, the adjusting slider 5 drives the hinged telescopic rod 6 to rotate. By the movement of the adjusting slider 5 and the gradual extension of the hinged telescopic rod 6 from the hinged sleeve 2, the ring-shaped hoisting frame 3 gradually rises.

[0049] When the annular square lifting frame 3 rises to the highest position, the annular square lifting frame 3 moves to the lower end of the limiting block 71, and at the same time the limiting slide column 61 rises to the uppermost end of the hinge sleeve 2, and the hinge sleeve 2 and the hinge telescopic rod 6 are in a vertical state, so that the adjusting slider 5 pushes the compression spring 42 to compress.

[0050] During the above process, as the hinged sleeve 2 and the hinged telescopic rod 6 gradually rotate out from the gap between the annular square hoisting frame 3 and the boss-type base 1 and are positioned on the front and rear sides of the building formwork, they block and limit the front and rear sides of the building formwork. At the same time, the positioning slide rod 7 limits the left and right ends of the building formwork, so that the building formwork is stably placed on the boss-type base 1. With the limiting effect of the positioning slide rod 7 and the hinged sleeve 2, the building formwork will not fall off the device even if it shakes during the hoisting process, thus ensuring the safety of the building formwork hoisting. Furthermore, since the building formwork does not need to be tied, the workload of the workers can be effectively reduced.

[0051] Then, external equipment can be used for hoisting, so that the annular square hoisting frame 3 can be lifted by multiple limiters, thereby raising the boss-type base 1 and hoisting the building formwork to the place of use.

[0052] When the building formwork needs to be unloaded, as the boss-type base 1 descends to the usage location, the external hoisting equipment continues to descend, causing the annular square hoisting frame 3 to gradually descend under its own weight and disengage from the limit block 71. At the same time, the compression spring 42 uses its elasticity to push the adjusting slider 5 to move, causing the adjusting slider 5 to drive the hinged telescopic rod 6 and the hinged sleeve 2 to adjust their angles and tilt at a certain angle. Then, the annular square hoisting frame 3 gradually descends under its own weight, causing the hinged telescopic rod 6 to gradually retract into the hinged sleeve 2, and its angle adjustment is used to gradually tilt it.

[0053] Once the ring-shaped hoisting frame 3 descends onto the boss-type base 1, the hinged telescopic rod 6 and the hinged sleeve 2 are then stored in the gap between the ring-shaped hoisting frame 3 and the boss-type base 1. After that, the workers can unload the building formwork from the boss-type base 1.
