Description

Technical Field

[0001] The utility model relates to the technical field of embedded technology for narrow and complex pipe wells, and more specifically, to an upward turning limit device for buried pipelines in narrow and complex pipe wells of high-rise buildings. Background Art

[0002] In current high-rise residential buildings, to ensure the usable area of indoor owners, the area of public areas is gradually compressed, and the size of the plumbing shaft is usually relatively narrow. However, with the rapid development of the construction industry and the increasing demands of owners, the functions of building mechanical and electrical engineering are becoming more and more, and the pipeline system is also increasing, which leads to the increasingly compressed space of the plumbing shaft where the space is already not sufficient. Subsequent pipeline construction technology and maintenance have become key and difficult points. To facilitate subsequent pipeline construction technology and maintenance, the upward turning of buried pipelines has become one of the preparatory links in building construction. The upward turning of buried pipelines refers to a laying method in which the pipelines originally buried underground need to bend upward and return above the ground or enter the building under specific conditions.

[0003] The traditional pipeline construction method is to first introduce the buried plastic pipelines into the plumbing shaft after laying the indoor buried pipelines. After the indoor pipeline construction is completed, the redundant pipelines in the plumbing shaft are cut off, and a hot-melt steel-plastic conversion joint is connected to the horizontal branch pipe in the plumbing shaft. The above method has low installation efficiency, cannot guarantee the horizontal and vertical perpendicularity of the buried plastic pipelines after upward turning, and the construction quality of the pipelines cannot be guaranteed due to the operation in a narrow space, and the work efficiency is also reduced, which cannot meet the requirements of the project.

[0004] Therefore, how to provide a limit device with simple structure, convenient use, recyclable and low cost to ensure the construction quality of buried pipelines after upward turning is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0005] For this reason, the purpose of the present utility model is to provide an upward turning limit device for buried pipelines in narrow and complex pipe wells of high-rise buildings, which solves the problems of low installation efficiency of the existing construction technology and inability to guarantee the horizontal and vertical perpendicularity of buried plastic pipelines after upward turning.

[0010] According to the technical solution of the present utility model, the bracket is made of section steel into a rectangular frame, and it has four auxiliary support legs at the bottom, and a vertically arranged limiting part is connected to the frame.

[0011] According to the technical solution of the present utility model, the limiting part is a semi-circular limiting pipe, and the pipe wall of the limiting pipe fits with the pipeline.

[0012] According to the technical solution of the present utility model, the fastener adopts a hoop.

[0013] According to the technical solution of the present utility model, an anti-loosening clamp is arranged at the joint of the hoop and the limiting part.

[0015] According to the technical solution of the present utility model, the support leg can be folded on the auxiliary support leg.

[0016] According to the technical solution of the present utility model, the support leg is connected to the bracket through a hinge.

[0017] It can be seen from the above technical solutions that compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] The technical solution of the present utility model integrates the up-turned pipes of buried pipelines in different systems and at different positions into an overall structure.

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0028] Since the traditional pipeline construction method has low installation efficiency, it cannot ensure the horizontal and vertical perpendicularity of the buried plastic pipeline after upward turning. At the same time, the construction quality of the pipeline cannot be guaranteed in the narrow space operation, and the work efficiency is also reduced, which cannot meet the requirements of the project.

[0029] In view of this, the present invention provides an upward turning limit device for buried pipelines in a narrow and complex pipe shaft of a high-rise building. Refer to the attached Figures 1-4 , including: a bracket 1, on which a plurality of vertically arranged limiting parts 4 can be connected according to the pipeline layout requirements; a fastener 5, which is connected through the fastener 5 after the limiting part 4 is attached to the pipeline; a leg 2, the bracket 1 is connected with a leg 2, and the bottom of the leg 2 is connected to a fixed buried plate 3.

[0030] The above technical solution can integrate the up-turned pipes of buried pipelines in different systems and at different positions into an integral structure. After the indoor buried pipelines are arranged, the mold can be directly placed in the pipe well without measuring and positioning each up-turned pipeline one by one. As long as the pipelines are placed on the limiting parts one by one and connected by fixing parts, the installation efficiency of the construction technology is improved, the horizontal and vertical perpendicularity of the buried plastic pipelines after up-turning is ensured, the operation is simple and convenient, it has the characteristics of prefabrication and batch production, and the investment of labor is reduced.

[0031] In the technical solution of the present utility model, the bracket 1 can be made of profiled steel into a rectangular frame, which has four auxiliary support legs at the bottom, and a vertically arranged limiting part 4 is connected to the frame. Among them, there are multiple cross bars horizontally arranged with the frame at the top of the frame, and multiple limiting parts 4 also correspond to the cross bars. Among them, the auxiliary support legs are vertically arranged with the top of the frame, which is convenient for supporting when just placed in the well.

[0032] Advantageously, the limiting part 4 is a semi-circular limiting pipe, and the pipe wall of the limiting pipe fits the pipeline. The semi-circular limiting pipe has a certain length, which is convenient for positioning the pipeline. In this way, the positioning is more accurate and convenient for construction.

[0033] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0034] In the embodiment of the present utility model, the fastener 5 adopts a hoop. An anti-loosening clamp is arranged at the joint of the hoop and the limiting part 4, and the clamp is tightened by bolts, which is convenient for limiting and fixing the pipeline.

[0035] In the above solution, the fixed buried plate 3 has multiple threaded holes and is installed on the ground of the shaft through expansion bolts.

[0036] More advantageously, the support leg 2 can be folded on the auxiliary support leg. The support leg 2 is connected to the bracket 1 through a hinge. The support leg can be welded by two steel pipes and connected by a hinge between them. It can be unfolded and fixed to the ground during use and folded and retracted after use, which is convenient for controlling the telescopic support leg. The above support legs are fixed around the bracket and can perform relative micro telescoping and torsion, which is suitable for different pipe well shapes.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0038] The present utility model utilizes prefabricated assembly technology and BIM modeling technology, combines the construction procedures and construction techniques of buried pipes, and is particularly applicable to the water heating shafts where the degree of repetition is high, the pipe wells are narrow and complex, and it is not convenient for personnel to enter the pipe wells for construction. Aiming at the pipeline installation techniques such as the horizontal and vertical fixation of the up - turned water supply, reclaimed water, and heating buried pipes after they enter the water heating shaft, it particularly relates to a limiting device for the up - turned limit of buried pipes in narrow and complex pipe wells of high - rise residences.

[0039] Process the support according to the construction location. After the pipeline is introduced into the water heating shaft, place the support and the support legs in the water heating shaft, put in the mold, and fix the fixed buried plate on the ground of the water heating shaft with expansion bolts. Heat - melt the up - turned elbow and up - turned pipe of the horizontal buried pipeline introduced into the water heating well, and the up - turned distance can be adjusted by itself to meet the technical requirements of the project's civil engineering. Then tightly fix the up - turned vertical plastic pipeline inside the limiting pipe. After confirming that there is no gap when it is tightly attached, firmly fix the hoop. And so on, after all the up - turned pipelines of the water supply, reclaimed water, and heating systems in the water heating shaft are fixed, pour the ground concrete, and pull out the mold before the concrete begins to set, so as to ensure the accurate positioning of the up - turned pipeline.
