Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a sleeve concentric positioning installation tool. Background Art

[0002] In recent years, many high-rise buildings under construction have several plumbing shafts installed. Each shaft is equipped with water supply risers, wastewater risers, heating risers, and even fire hydrant system risers. When installing these pipes, they need to be pre-buried in the position where they pass through the floor slab, and the pre-buried casings in the two adjacent floor slabs must correspond one to one up and down.

[0003] In the prior art, wooden wedges are usually used to fix the casing and then cast it. However, the existing casing installation method has poor molding effect, difficulty in concentrically stabilizing the casing, narrow construction working surface and difficult operation, and difficulty in fixing the formwork with wooden wedges, thereby reducing the construction quality qualification rate, prolonging the construction time and affecting work efficiency.

[0009] The limiting hole is formed on the fixing block, and the limiting hole extends to the center position of the fixing block.

[0010] The jacks are symmetrically arranged on the fixing block at positions on both sides close to the limiting holes.

[0011] More preferably, there are multiple mounting rods, and the multiple mounting rods are vertical and parallel to each other.

[0012] Further preferably, one end of the plurality of fixing rods away from the fixing block is commonly fixed to the inner ring of the annular fixing frame, and the installation positions of the plurality of fixing rods correspond to the position of the installation rod.

[0013] More preferably, the opening direction of the limiting hole corresponds to the opening position of the installation opening, and the latch is inserted into the limiting hole.

[0014] Further preferably, a hook is installed at the bottom of the steel wire rope, and the counterweight is hung on the bottom of the steel wire rope through the hook.

[0015] Compared with the prior art, the utility model has the following advantages: by fixing the position of the steel wire rope, the steel wire rope limits the position of the installation rod, the annular fixing frame and the limit assembly at the casting position, and then when the casing is sleeved on the installation rod and the annular fixing frame, the accuracy of the casing position at the casting position is improved, and the stability of the casing casting is further improved.

[0020] The following is combined with Figures 1 to 3 The utility model is further introduced in detail.

[0021] A casing concentric positioning installation tool, such as Figure 1 As shown, it includes a mounting rod 1, on which a plurality of annular fixing frames 2 are installed at equal intervals along the length direction. Furthermore, the number of the annular fixing frames 2 is three, and a limiting assembly 3 is installed at the inner circle position of the annular fixing frame 2 near the top and bottom ends of the mounting rod 1. Specifically, the mounting rod 1, the annular fixing frame 2 and the limiting assembly 3 together constitute an installation tool. Further, the height of the installation tool is greater than the height of the installation sleeve, a pin 4 is inserted into the limiting assembly 3, and an installation opening 5 is opened on one side of the annular fixing frame 2. A steel wire rope 6 is commonly arranged between the two limiting assemblies 3, and a counterweight block 8 is arranged at the bottom of the steel wire rope 6.

[0022] By fixing the position of the steel wire rope 6, the steel wire rope 6 limits the position of the installation rod 1, the annular fixing frame 2 and the limit assembly 3 at the casting position. Then, when the casing is sleeved on the installation rod 1 and the annular fixing frame 2, the accuracy of the casing position at the casting position is improved, and the stability of the casing casting is further improved. At the same time, the construction quality qualification rate is improved, the operational difficulties caused by the narrow working surface are reduced, and the casing can be effectively installed in a narrow working surface, thereby shortening the construction time and improving the construction efficiency.

[0023] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the limiting component 3 includes:

[0024] There are three fixing rods 31 , which are fixedly connected to the inner circle of the annular fixing frame 2 along the circumferential direction.

[0025] The fixing block 32 is fixedly connected to the opposite end of the plurality of fixing rods 31 , and the fixing block 32 is located at the center of the annular fixing frame 2 .

[0026] The limiting hole 33 is formed on the fixing block 32 , and the limiting hole 33 extends to the center of the fixing block 32 . Furthermore, the limiting hole 33 can be formed in a vertical direction or an inclined direction.

[0027] The insertion holes 34 are symmetrically arranged on the fixing block 32 near the two sides of the limiting hole 33 .

[0028] Furthermore, when in use, the steel wire rope 6 is clamped in the limiting hole 33, and the latch 4 is inserted in the insertion hole 34, so as to fasten the steel wire rope 6, thereby improving the stability of tool installation and further improving the stability of casing casting.

[0029] Specifically, Figure 1 and Figure 2 As shown, there are multiple installation rods 1, and the multiple installation rods 1 are vertical and parallel to each other, which improves the stability of tool installation when in use.

[0030] Specifically, one end of the plurality of fixing rods 31 away from the fixing block 32 is commonly fixed to the inner circle of the annular fixing frame 2, and the installation positions of the plurality of fixing rods 31 correspond to the position of the installation rod 1, further improving the stability of the tool when in use.

[0031] Specifically, the opening direction of the limiting hole 33 corresponds to the opening position of the installation opening 5, and the pin 4 is inserted into the limiting hole 33, which facilitates the wire rope 6 to be clamped in the limiting hole 33 during use. The pin 4 prevents the wire rope 6 from escaping, further improving the stability of the tool use and the stability of the casing casting.

[0032] Specifically, a hook 7 is installed at the bottom of the steel wire rope 6 , and the counterweight 8 is hung on the bottom of the steel wire rope 6 through the hook 7 .

[0033] How it works

[0034] When in use, first place the installation tool as a whole vertically at the position of the reserved hole to be poured, extend the wire rope 6 from the installation port 5 to the position of the limit hole 33, insert the pin 4 into the socket 34, and fasten the socket 34 with the pin 44. Then move the position of the wire rope 6, ensure that the wire rope 6 is located in the center of the reserved hole as much as possible, and tie a knot to fix the top of the wire rope 6. The counterweight block 8 is hung on the bottom of the wire rope 6 through the hook 7. At this time, place the casing to be poured on the outside of the installation tool for pouring.

[0035] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
