Technical Field

[0001] The utility model relates to the technical field of casing construction, in particular to a casing auxiliary positioning device. Background Art

[0002] As the name implies, a pipe shaft is a space for laying various pipes. A pipe shaft is a vertical pipe centralized installation area with a large variety and quantity of pipes. Therefore, there are many types and quantities of casings passing through the floor slab. In a pipe shaft, the common method for casings is to reserve holes, then install pipes and reserve casings, and finally set up supports, formwork, implant steel bars, pour concrete, cure, and then remove the formwork in the pipe shaft.

[0003] The existing reserved casing molds are time-consuming and cumbersome during construction positioning, and are inconvenient to fix after positioning, which easily leads to position deviation. When the construction positions of upper and lower floors such as in a building are the same, the position deviation may cause the later construction pipes to be inclined, making it inconvenient to use. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the utility model provides a casing auxiliary positioning device, and the specific technical solutions are as follows:

[0015] In summary, the present utility model includes at least one of the following beneficial effects:

[0016] 1. By designing a steel plate bottom form that is adapted to the size of the reserved hole for pre-positioning, and prefabricating all the reserved sleeves on the steel plate bottom form, the bottom form sleeves of the pipe well are modularized. The modularized set of fixings can reduce the positioning deviation between the reserved sleeves on different floors and improve the installation accuracy. After the installation of various pipelines is completed, concrete can be directly poured on the steel plate bottom form to complete the plugging of the reserved hole and the reserved sleeve. When pouring concrete, there is no need to additionally formwork and remove the formwork, which is convenient and practical.

Specific implementation manners

[0024] The following further elaborates on the present utility model in conjunction with the Figures 1-4 accompanying drawings.

[0025] An embodiment of the present utility model discloses a sleeve auxiliary positioning device. Referring to Figures 1-2 , it includes a pipe shaft floor slab 1. A reserved hole 11 is provided inside the pipe shaft floor slab 1. A steel plate bottom mold 2 that is adaptively arranged is movably provided at the inner bottom of the reserved hole 11 of the pipe shaft floor slab 1. The inner side wall of the pipe shaft floor slab 1 is in abutting connection with the outer side wall of the steel plate bottom mold 2, so that the pipe shaft floor slab 1 can assist in positioning the steel plate bottom mold 2 through the reserved hole 11, and the steel plate bottom mold 2 is the pipe shaft bottom plate.

[0026] Referring to Figures 1-2 , a plurality of reserved sleeves 21 are fixedly provided in the middle of the steel plate bottom mold 2. The steel plate bottom mold 2 can support and fix the reserved sleeves 21. Among them, the reserved sleeves 21 can be prefabricated on different steel plate bottom molds 2 through the shaping and positioning of the mold, so that the positions of the reserved sleeves 21 on different steel plate bottom molds 2 can correspond one by one when removed from the mold, thus playing a role in auxiliary positioning.

[0027] Referring to Figures 3-4 , two groups of symmetrically distributed annular reinforcements 31 are slidably provided on the top of the steel plate bottom mold 2. Two groups of symmetrically distributed sliding grooves 22 are provided on the top of the steel plate bottom mold 2. Sliders 3 are slidably provided in both groups of sliding grooves 22. The annular reinforcements 31 are fixedly provided on the top of the sliders 3. The sliding grooves 22 can connect the sliders 3 and the steel plate bottom mold 2. The sliders 3 can connect the steel plate bottom mold 2 and the annular reinforcements 31. The annular reinforcements 31 are annular steel bars, and the longitudinal section of the slider 3 is in the shape of an inverted "T", so that the slider 3 can slide in the sliding groove 22 without detaching.

[0028] Referring to Figures 1-3, a limiting component is provided at the bottom of the annular rib 31. The limiting component includes a return spring 4 fixedly provided on the side of the slider 3 away from the reserved sleeve 21, and a rotating rod 41 fittingly inserted on the other side of the slider 3. One end of the return spring 4 is fixedly provided on one side of the chute 22, and one end of the rotating rod 41 is rotatably provided on the other side of the chute 22. The steel plate bottom mold 2 can support and hide the return spring 4 through the chute 22, and the steel plate bottom mold 2 can conveniently limit the rotating rod 41 through the chute 22.

[0029] Refer to Figures 1-3 , a slot 32 is formed on one side of the slider 3, and one end of the rotating rod 41 is fittingly inserted into the slot 32. After the rotating rod 41 rotates, one end can be inserted into the slot 32. Thus, under the elastic force of the return spring 4 on the slider 3, one end of the rotating rod 41 can press against the slider 3 to limit the slider 3. A pull ring 42 is fixedly provided at the top of the rotating rod 41, and people can lift and rotate the rotating rod 41 through the pull ring 42.

[0030] Refer to Figure 1 and Figure 3 , at the top of the inner sides of the two groups of annular ribs 31, transverse ribs 12 are both fittingly abutted. The two groups of transverse ribs 12 are respectively fixedly provided on both sides of the reserved hole 11. One end of the transverse rib 12 is embedded in the pipe well floor slab 1. The transverse rib 12 can hang the abutted annular rib 31, thereby supporting the steel plate bottom mold 2. The return spring 4 is located directly below the transverse rib 12, facilitating the slider 3 to be pushed to a position away from the transverse rib 12 under the elastic force of the return spring 4.

[0031] Refer to Figure 1 and Figure 3 , a first annular groove 23 is formed at the top of the outer side wall of the steel plate bottom mold 2. A first sealing ring 5 that fittingly abuts against the reserved hole 11 is movably provided in the first annular groove 23 of the steel plate bottom mold 2. The steel plate bottom mold 2 can support and limit the first sealing ring 5 through the first annular groove 23.

[0032] Refer to Figure 1 and Figure 3 , a second annular groove 24 is formed at the bottom of the outer side wall of the steel plate bottom mold 2. A second sealing ring 51 that fittingly abuts against the reserved hole 11 is movably provided in the second annular groove 24 of the steel plate bottom mold 2. The steel plate bottom mold 2 can support and limit the second sealing ring 51 through the second annular groove 24. The first sealing ring 5 and the second sealing ring 51 can double-seal the connection between the pipe well floor slab 1 and the steel plate bottom mold 2, preventing water inside the concrete from flowing down through the connection between the pipe well floor slab 1 and the steel plate bottom mold 2 during concrete pouring and causing leakage.

[0033] The implementation principle of a sleeve auxiliary positioning device in an embodiment of the present utility model is as follows:

[0034] During use, people can design a steel plate bottom mold 2 that fits the size of the reserved hole 11 to assist in pre-positioning, so that the steel plate bottom mold 2 forms the bottom plate of the pipe well. All the reserved sleeves 21 are prefabricated on the steel plate bottom mold, making the pipe well bottom mold sleeves modular. The positions of the prefabricated reserved sleeves 21 on the steel plate bottom molds 2 of different floors can correspond one by one, thereby reducing the positioning deviation between the reserved sleeves of different floors.

[0035] During installation, people can insert the steel plate bottom mold 2 from the bottom of the pipe well floor 1 into the lower opening of the reserved hole 11. At this time, under the elastic force of the return spring 4, the ring rib 31 and the slider 3 will be pushed to the side away from the inner wall of the reserved hole 11. When the steel plate bottom mold 2 is inserted, the ring rib 31 will move away from the cross rib 12, so that the cross rib 12 will not obstruct the process of the steel plate bottom mold 2 entering the reserved hole 11.

[0036] Then people can rotate the rotating rod 41 through the pull ring 42 so that one end of the rotating rod 41 can be inserted into the slot 32 of the slider 3 after rotation to compress the return spring 4. At this time, under the rotation and push of the rotating rod 41, the ring rib 31 will move with the slider 3, so that the ring rib 31 can be hung on the cross rib 12 after moving to support the steel plate bottom mold 2 in the reserved hole 11.

[0037] After people set the pipeline into the reserved sleeve 21, they can pour concrete onto the steel plate bottom mold 2. At this time, after the concrete solidifies, it can seal the reserved hole 11 and the reserved sleeve 21.

[0038] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
