Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a prefabricated column installation and positioning device. Background Art

[0002] In order to shorten the construction period, many building components are constructed using prefabricated installation methods, such as assembled prefabricated frame columns. During the hoisting construction of assembled prefabricated frame columns, the prefabricated columns are slowly lifted by lifting equipment. When they are lifted to a certain height from the ground, the installation workers check the positioning lines on the floor, stabilize the prefabricated columns, and check whether the sleeve holes of the prefabricated columns are aligned with the positions of the connecting steel bars. After the inspection is qualified, they are slowly lowered for installation.

[0003] The existing positioning and adjustment device for prefabricated column installation with publication number CN111424996A comprises a measuring mechanism and an adjusting mechanism, wherein the measuring mechanism is used to measure the position information of the prefabricated column, and the adjusting mechanism is used to adjust the position of the prefabricated column according to the position information so that the prefabricated column corresponds to the mounting seat below the prefabricated column; however, the existing positioning and adjustment device for prefabricated column installation still has certain shortcomings: it is necessary to control multiple mortgage parts to abut and fix with the prefabricated column by adjusting multiple screws, which is time-consuming and labor-intensive to operate, and during the installation process, the mortgage parts rub against the surface of the prefabricated column, which will cause serious wear and tear after long-term use, thereby greatly shortening the life of the structure. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a prefabricated column installation and positioning device which is easy to install and operate and can ensure that the structure can be used for a long time.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0007] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0008] This device uses the slide grooves of the right splicing steel block and the left splicing steel block to relatively fix the position of the bottom plate and the dowel, and uses the limit plate to limit the prefabricated column so that the prefabricated column can be accurately inserted into the dowel. In order to avoid serious wear on the surface of the limit plate, a first wear-resistant steel plate that can be disassembled and assembled is provided on the limit plate. Similarly, a second wear-resistant steel plate is also provided at the bottom of the bottom plate. The steel plate itself has a hard texture and a long structural life. After a long period of use, the first wear-resistant steel plate and the second wear-resistant steel plate can be replaced, thereby extending the service life of the device.

[0009] As a preferred embodiment, a further technical solution of the utility model is:

[0010] Preferably, the first connecting plate and the first wear-resistant steel plate, as well as the second connecting plate and the second wear-resistant steel plate, are connected and fixed by fastening bolts, so as to facilitate replacement of the first wear-resistant steel plate and the second wear-resistant steel plate.

[0013] Preferably, a steel gasket is also provided on the upper surface of the ground corresponding to the prefabricated column pre-installation position; after the prefabricated column is inserted into the dowel, its bottom will abut against the surface of the steel gasket.

[0024] like Figures 1 to 4This embodiment provides a prefabricated column installation and positioning device. A plurality of evenly distributed dowel bars 3 are arranged on the upper surface of the ground 1 where the prefabricated column is preinstalled. Two bottom plates 8 are arranged on both sides of the dowel bars 3 on the ground 1. The bottom plates 8 are provided with limit plates 7 for limiting the prefabricated column. The limit plates 7 are arranged perpendicular to the bottom plates 8. The upper edge of the limit plates 7 is detachably connected to a first wear-resistant steel plate 9 through a first connecting plate. The lower side of the bottom plate 8 is detachably connected to a second wear-resistant steel plate 10 through a second connecting plate. The first connecting plate and the first wear-resistant steel plate 9, and the second connecting plate and the second wear-resistant steel plate 10 are connected and fixed by fastening bolts 21 and matching nuts. A connecting block is welded on the side of the bottom plate 8 close to the dowel bars 3. A right splicing steel block 12 is arranged on the connecting block. A left splicing steel block 13 is connected to the right splicing steel block 12. A through groove is opened on the side opposite to the right splicing steel block 12. The through groove matches the outer diameter of the dowel bars 3.

[0025] The surface of the prefabricated column 2 abuts against the surface of the first wear-resistant steel plate 9 , and the ground 1 abuts against the bottom surface of the second wear-resistant steel plate 10 .

[0026] During the descent of the prefabricated column 2, in order to avoid serious wear on the surface of the limit plate 7, a disassembled first wear-resistant steel plate 9 is provided on the limit plate 7. Similarly, a second wear-resistant steel plate 10 is also provided at the bottom of the base plate 8. The steel plate itself has a relatively hard texture and a long structural life. After a long period of use, it can be removed and replaced with a new one by tightening the bolts 21. Compared with other positioning devices, this design allows users to only replace the parts of the structure that are prone to wear, thereby reducing the cost of use.

[0027] like Figure 4 As shown, the left spliced ​​steel block 13 is slidably connected to the right spliced ​​steel block 12, and the sliding connection structure is: sliding grooves 14 are opened on both sides of the through groove of the right spliced ​​steel block 12, and sliders 15 are set on both sides of the through groove of the left spliced ​​steel block 13 corresponding to the sliding grooves 14, and the sliders 15 are slidably connected to the sliding grooves 14; a limiting groove 17 is opened on the surface of the sliding groove 14, and a limiting block 16 is welded on the surface of the slider 15, and the limiting block 16 matches the limiting groove 17.

[0028] like Figure 1 As shown, a handle 11 is welded to a side wall surface of the left spliced ​​steel block 13 relative to the right spliced ​​steel block 12 , and a plurality of evenly distributed anti-slip strips 20 are fixedly connected to the surface of the handle 11 .

[0029] The device is convenient for fixing the positioning device. During operation, the prefabricated column 2 is firstly hoisted to a height of about 50 cm above the ground 1 by an external hoisting machine, and then the bottom plate 8 is pushed horizontally to align the through groove on the surface of the right spliced ​​steel block 12 with the dowel 3 on one side, and then the slider 15 on the surface of the left spliced ​​steel block 13 is aligned with the slide groove 14 on the surface of the right spliced ​​steel block 12 and inserted. At this time, the bottom plate 8 is fixed to the position on one side of the dowel 3. Since the prefabricated column 2 mainly swings horizontally, it will not affect the fixation between the left spliced ​​steel block 13 and the right spliced ​​steel block 12. Then, under the restriction of the limit plates 7 on both sides, the precast column 2 stops swinging and is located directly above the dowel rod 3. The precast column 2 will be accurately inserted into the dowel rod 3 and will stop descending immediately after the dowel rod 3 is inserted. At this time, the left spliced ​​steel block 13 is removed using the handle 11, and the positioning device is removed. The structure can avoid the possible risks of people extending their hands directly under the precast column 2 by setting the handle 11. After the removal is completed, the precast column 2 can be completely lowered and the bottom can be sealed with cement. In this process, the installation and removal of the positioning device can be completed quickly, and the structure has strong stability.

[0030] like Figure 2 As shown, a steel gasket 4 is arranged on the upper surface of the ground 1 between a plurality of dowel bars 3 , and a prefabricated column 2 is arranged on the upper side of the steel gasket 4 .

[0031] After the prefabricated column 2 is inserted into the dowel 3, its bottom will abut against the surface of the steel gasket 4. At this time, the user can fill the gap between the prefabricated column 2 and the ground 1 with cement so that the structure can remain stable on the ground 1.

[0032] like Figure 1 , Figure 3 As shown, the upper surfaces of the two bottom plates 8 are symmetrically connected to the fixing columns 5 by bolts, the inside of the fixing columns 5 is slidably connected to the adjusting rods 6, the top of the adjusting rods 6 is welded with the mounting plate 22, the lower edge of the limiting plate is provided with a third connecting plate extending outward corresponding to the mounting plate 22, and the mounting plate 22 is connected to the limiting plate 7 through the third connecting plate. The adjusting rods 6 and the fixing columns 5 in the device are connected in a sliding manner, so the user can collapse the structure after use, thereby reducing the space occupied during transportation.

[0033] like Figure 1 As shown, a threaded rod 19 is threadedly connected to the side wall surface of the fixed column 5, one end of the threaded rod 19 extends into the interior of the fixed column 5 and abuts against the surface of the adjusting rod 6, and one end of the threaded rod 19 located outside the fixed column 5 is fixedly connected to a turning handle.

[0034] The user rotates the threaded rod 19 by the turning handle so that the end of the threaded rod 19 abuts against the surface of the adjusting rod 6 inside the fixed column 5, so that the limiting plate 7 on the top of the adjusting rod 6 can be at the correct horizontal height to limit the prefabricated column 2.

[0035] Since the prefabricated column 2 has a large mass and is prone to lateral swing during the hoisting process, Figure 1 As shown, in this embodiment, a support rod 18 is welded between the bottom plate 8 and the fixing column 5 so that the structure can remain stable during operation.

[0036] The working principle of a positioning device for prefabricated column installation provided by the utility model is as follows:

[0037] The first step: The device is more convenient for fixing the positioning device. During operation, first use an external lifting machine to lift the prefabricated column 2 to a height of about 50 cm above the ground 1, then push the bottom plate 8 horizontally, so that the through groove on the surface of the right spliced ​​steel block 12 is aligned with the dowel 3 on one side, and then align the slider 15 on the surface of the left spliced ​​steel block 13 with the slide groove 14 on the surface of the right spliced ​​steel block 12 and insert it. At this time, the bottom plate 8 is fixed to the position on one side of the dowel 3. Since the prefabricated column 2 mainly swings horizontally, it will not affect the fixation between the left spliced ​​steel block 13 and the right spliced ​​steel block 12. Then, under the restriction of the limit plates 7 on both sides, the prefabricated column 2 stops swinging and is located directly above the dowel 3. The prefabricated column 2 will be accurately inserted into the dowel 3 and will stop descending immediately after the dowel 3 is inserted. At this time, the left splicing steel block 13 is removed by using the handle 11, and the positioning device is removed. The structure can avoid the possible risk of people reaching directly under the prefabricated column 2 by setting the handle 11. After the removal is completed, the prefabricated column 2 can be completely put down and the bottom can be sealed with cement. In this process, the installation and removal of the positioning device can be completed quickly, and the structure has strong stability.

[0038] The second step: during the descent of the prefabricated column 2, in order to avoid serious wear on the surface of the limit plate 7, a first wear-resistant steel plate 9 that can be disassembled and assembled is set on the limit plate 7. Similarly, a second wear-resistant steel plate 10 is also set at the bottom of the base plate 8. The steel plate itself has a hard texture and a long structural life. After a long period of use, it can be removed and replaced with a new one by tightening the bolts 21. Compared with other positioning devices, this design allows users to only replace the parts of the structure that are prone to wear, thereby reducing the cost of use.
