In building construction, the hoisting of PC columns is often involved to achieve the purpose of rapid construction. In order to ensure the quality of the building, the verticality of the PC columns needs to be corrected after the hoisting is completed.

[0003] The verticality of the existing PC column is composed of 2 sets of oblique adjustable screws, and the verticality of the PC column is adjusted by adjusting the length of the screws on both sides.

[0004] After the PC column is hoisted into place, the verticality of the PC column is checked with a ruler. If there is any deviation, it can be adjusted with an adjustable screw. The prefabricated column or prefabricated wall is connected and fixed to the cast-in-place structure through an adjustable screw.

[0005] Since the existing PC column verticality correction is relatively cumbersome, in order to further improve the convenience of PC column verticality adjustment, it is necessary to provide a new PC column verticality adjustment tool. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a PC column verticality adjustment tool, which can conveniently determine the verticality of the PC column and make rapid corrections; at the same time, it ensures that the supporting function is not affected, facilitates the operation of operators, and improves the efficiency of operators.

[0007] The technical solution adopted by the utility model to solve the above technical problems is to provide a PC column verticality adjustment tool, including a support screw and a plumb bob, the support screw is a support screw with adjustable length, one end of the support screw is an upper fixing piece fixedly connected to the PC column, and the other end of the support screw is a lower fixing piece fixedly connected to the horizontal floor slab, the upper fixing piece and the lower fixing piece are free chain structures with adjustable angles, the plumb bob is connected to a wire box through a nylon rope, and the wire box is installed on the PC column through a fixing plate.

[0008] The above-mentioned PC column verticality adjustment tool, wherein the upper fixing member is provided with an angle indicator plate and a vertical pointer, and the vertical pointer is always along the direction of gravity.

[0009] The above-mentioned PC column verticality adjustment tool, wherein the fixing plate is tied to the PC column by a fixing rope.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the PC column verticality adjustment tool provided by the utility model replaces the traditional ruler, and the verticality of the PC column is judged by checking the plumb bob and the nylon rope, and then the purpose of PC column verticality correction is achieved by adjusting the supporting screw; at the same time, it is ensured that the supporting function is not affected, the operation of the operator is convenient, and the efficiency of the operator is improved.

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Figure 1 It is a schematic diagram of the structure of the PC column verticality adjustment tool of the utility model.

[0020] See also Figure 1 The utility model provides a PC column verticality adjustment tool, including a support screw 3 and a plumb bob 4, the support screw 3 is a length-adjustable support screw, one end of the support screw 3 is an upper fixing member 1 fixedly connected to the PC column 8, and the other end of the support screw 3 is a lower fixing member 2 fixedly connected to the horizontal floor slab 9, the upper fixing member 1 and the lower fixing member 2 are free chain structures with adjustable angles, the plumb bob 4 is connected to the wire box 6 through a nylon rope 5, and the wire box 6 is installed on the PC column 8 through a fixing plate 7.

[0021] The PC column verticality adjustment tool provided by the utility model has a support screw 3 that can achieve the function of fixed support, with a diameter of about 30 mm, and the screw length can be adjusted at the same time. The wire box 6 is used to store the nylon rope 5, and the depth of the wire box is about 100 mm from the PC column. The nylon rope 5 is used to connect the wire box 6 and the plumb bob 4, and the plumb bob 4 is always vertically downward. The fixing plate 7 prevents the plumb system from falling due to gravity. The vertical dimension of the fixing plate 7 is about 150 mm, and it is tied to the PC column 8 by the fixing rope. The PC column verticality adjustment tool provided by the utility model replaces the traditional ruler, and the verticality of the PC column is judged by checking the plumb bob 4 and the nylon rope 5, and then the verticality correction of the PC column 8 is achieved by adjusting the support screw 3.
