Description

Technical Field

[0001] The invention relates to the technical field of prefabricated building construction, and in particular to auxiliary equipment for installing prefabricated building walls. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. When installing building walls, the steel bars on the assembly plane need to be accurately inserted into the grouting sleeves in the wall, and then the wall surface is grouted and fixed.

[0003] During the assembly process of some walls, the steel bars need to be straightened first so that they are in a vertical state to facilitate their insertion into the grouting sleeves in the wall. Currently, this operation is mostly done by manual straightening of the steel bars. Some straightening equipment is also used to straighten the steel bars, but this type of equipment needs to adjust its position multiple times to complete the straightening of all the steel bars, which makes the wall assembly efficiency low. In addition, walls are usually installed by hoisting, and during this process, multiple workers are required to push the wall to adjust its position until the steel bars enter the grouting sleeves of the wall. This process is time-consuming and labor-intensive, which increases the difficulty of wall installation. In addition, the joint end faces of the wall need to be kept clean to ensure the firmness of the mortar at the bottom of the wall. Currently, this cleaning operation needs to be done manually, which further reduces the wall assembly efficiency. Summary of the invention

This setting can block impurities swept from the bottom surface of the wall 11, reduce impurities falling from the "U"-shaped groove to the ground, reduce the pollution of the connecting surface, and the steel bar 10 can pass through the contact gap position of the two flexible shielding sheets, without affecting the steel bar 10 entering the grouting sleeve of the wall 11; during the descent of the lifting plate 3, the cleaning component 8 can clean the bottom surface of the wall 11, realize the synchronous operation of assembling and cleaning the wall 11, and after the entire auxiliary equipment is moved out of the construction position, the impurities on its surface can be cleaned.

[0035] The working principle of the present invention is as follows:

[0036] When it is necessary to install the prefabricated building wall 11, the auxiliary equipment is first pushed to the position of the steel bar 10 on the assembly plane 9, and the steel bar 10 is inserted into the "U"-shaped groove of the bottom plate 1 and the lifting plate 3, and the motor 45 is started to drive the lead screw 44 to rotate. The lead screw 44 drives the lower sliders 41 at both ends to slide close to each other, so that the lower slider 41 drives the upper slider 43 to slide through the top support rod 42. At this time, the lifting plate 3 slides upward on the guide column 2; the upper slider 43 drives the first driving plate 61 to slide through the connecting plate 63, and the first driving plate 61 pushes the sliding column 52 through the driving block 62 connected thereto, so that the sliding column 52 drives the straightening block 53 to extend to the outside of the lifting plate 3. When the two straightening blocks 53 are fitted together, a circular straightening hole is formed, and the steel bar 10 is located in the straightening hole. The straightening block 53 is driven upward by the lifting plate 3 to realize the overall straightening operation of the steel bar 10.

[0037] The wall 11 is hoisted to the position above the auxiliary equipment. During the upward movement of the lifting plate 3, the lifting plate 3 pulls the pull rope 75, so that the pull rope 75 drives the positioning wall 72 to rotate, and the positioning wall 72 drives the positioning block 73 connected thereto to contact the edge of the wall 11. After the positioning block 73 contacts the edge of the wall 11, it continues to move, so that the positioning block 73 pushes the wall 11. When the four positioning blocks 73 move to the highest point, they can form a rectangular area, which just positions the wall 11 directly above the steel bar 10 and aligns the steel bar 10 with the grouting sleeve hole in the wall 11.

[0038] The wall 11 is slowly lowered so that the steel bar 10 enters the grouting sleeve of the wall 11, and the bristles of the cleaning brush 82 are in contact with the bottom surface of the wall 11, and then the wall 11 and the lifting plate 3 move downward synchronously. During this process, the gear 84 and the rack 85 produce relative movement, the gear 84 rotates, and the gear 84 drives the coaxial turntable 83 to rotate, so that the driving column on the turntable 83 slides in the straight groove ring 87, and the straight groove ring 87 drives the driving frame 86 to make a linear reciprocating motion, thereby driving each cleaning brush 82 to move horizontally and linearly through the second driving plate 81, thereby realizing the cleaning operation of the bottom surface of the wall 11.

[0039] The present invention integrates the functions of straightening the steel bars 10 during the installation of the prefabricated building wall 11, assisting the alignment of the grouting sleeves between the steel bars 10 and the wall 11, and cleaning the bottom surface of the wall 11, and can realize the rapid auxiliary installation of the prefabricated building wall 11, thereby improving the assembly efficiency of the wall 11.
