Description

Technical Field

[0001] The utility model relates to the technical field of EMC precast laminated shear wall construction, and particularly to a rapid leveling system for EMC precast shear walls. Background Technique

[0002] In existing practices, the horizontal adjustment techniques for EMC (prestressed concrete) precast shear walls mainly include two strategies. First, the first strategy involves deploying plastic shims at the bottom of precast wall panels for height correction. The length and width of these shims shall not exceed the limit of 80 mm, and their thickness is carefully selected according to the horizontal gap height measured on site. Usually, a series of shims with an increment of 5 mm are available for selection. Before installation, the required shim thickness is determined through precise measurement and fixed to the floor slab using cement nails to prevent displacement during the installation process. However, since the minimum step for shim thickness adjustment is 5 mm, this method has limitations in terms of accuracy and is difficult to achieve fine adjustment.

[0003] Secondly, another method is to pre-embed sleeves at the bottom of the wall panel during the precast stage, aiming to finely control the elevation of the wall panel by inserting adjustment screws subsequently. During implementation, the screws need to be screwed into the pre-embedded sleeves before the hoisting operation. Although this solution theoretically provides a more flexible adjustment mechanism, in practice, it faces challenges: the incomplete flatness of the top surface of the building results in the need for repeated fine adjustment of the wall to achieve horizontal. Coupled with the huge weight of the precast wall panel itself, once placed on the floor slab, the adjustment screws often become fixed due to bearing the entire weight, making further adjustment difficult. Usually, it is necessary to use a tower crane to lift the wall again to continue the adjustment, which undoubtedly delays the hoisting process and affects the overall progress of the project.

[0004] Therefore, there is an urgent need for a new device to solve the problem that the original leveling system needs to be adjusted multiple times by a tower crane, which affects the hoisting progress, and also avoid the problem of damage to precast components caused by the original crowbar installation and positioning method.

[0005] Therefore, the utility model proposes a rapid leveling system for EMC precast shear walls to solve the above problems. Content of the Utility Model

[0038] Embodiment III

[0039] On the basis of Embodiment II, a movable ball 9 is provided to be adapted to a ball chute 8. A linear bearing rod 17 is arranged inside the transverse moving frame 10. There are two groups of the linear bearing rods 17, and the two groups of the linear bearing rods 17 are respectively located on both sides inside the transverse moving frame 10;

[0040] A guiding hole 18 is formed on the surface of the longitudinal moving frame 14. The guiding hole 18 penetrates through the longitudinal moving frame 14. There are two groups of the guiding holes 18, and the two groups of the guiding holes 18 are symmetrically distributed about the central axis of the longitudinal moving frame 14. The inside of the guiding hole 18 and the outer wall of the linear bearing rod 17 are in sliding connection;

[0041] During use, while driving the transverse moving frame 10 and the longitudinal moving frame 14 to move through the sliding device 12, the movable ball 9 correspondingly rolls in the ball chute 8. Similarly, the linear bearing rod 17 correspondingly slides in the guiding hole 18, thereby respectively providing guiding and supporting effects for the movement of the transverse moving frame 10 and the longitudinal moving frame 14, and improving the stability of the device;

[0042] The sliding device 12 includes a square plate 20, a vertical plate 21, a rotating lever and rollers 16. Four groups of the sliding devices 12 are provided at the bottoms of both the transverse moving frame 10 and the longitudinal moving frame 14. The four groups of the sliding devices 12 are respectively arranged at the four ends of the lower surfaces of the transverse moving frame 10 and the longitudinal moving frame 14. The rollers 16 can respectively roll on the bottom wall of the bottom frame 2 and the transverse moving frame 10. The rollers 16 are located at the middle positions of the rotating rods 13.

[0043] During use, the roller 16 is fixed at the middle position of the rotating rod 13 to ensure the stability of the lateral moving frame 10 and the longitudinal moving frame 14 during movement and avoid deviation.

[0044] The hydraulic claw jack 6 is fixed inside the longitudinal moving frame 14 by bolts, and an angle steel 7 is fixed to the L-shaped claw of the hydraulic claw jack by welding.

[0045] During use, considering that the EMC precast composite shear wall is relatively heavy and the L-shaped claw of the jack used has a relatively compact design and a very small contact area, which results in a very large pressure on the contact point and is likely to cause damage to the corners of the component. Therefore, in order to ensure that the wall is not locally damaged during the elevation adjustment process, a protection measure is taken, that is, an angle steel 7 is added as a reinforcement pad at the contact point between the L-shaped claw and the bottom end of the wall to disperse the pressure and protect the component intact.

[0046] Working principle: In actual use, this device does not require the long-term cooperation of a tower crane for installation, nor does it require multiple hoisting and adjustment. The tower crane hoists the wall to the installation position, roughly adjusts the installation and installs the inclined strut, and then the hook can be removed. Then, with the help of this auxiliary positioning and leveling device, the rapid positioning and leveling of the precast composite shear wall can be achieved. The horizontal longitudinal and lateral adjustment of the hydraulic claw jack 6 can be realized through the sliding device 12 installed at the bottom of the lateral moving frame 10 and the longitudinal moving frame 14, and the vertical height adjustment can be realized through the set hydraulic claw jack 6. This method is simple, convenient and fast, does not require multiple hoisting and adjustment by the tower crane, and can achieve the fast and accurate positioning and leveling of the precast composite shear wall. At the same time, by adding an angle steel 7 as a reinforcement pad at the contact point between the L-shaped claw and the bottom end of the wall to disperse the pressure and protect the component intact, the problem of multiple adjustments of the original leveling system affecting the hoisting progress is solved, and the problem of damage to the precast component by the original crowbar installation and positioning method is also avoided.

[0047] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
