Description

Technical Field

[0001] This utility model relates to the field of pre-embedded pipe casing technology for water and heating wells in building engineering, and in particular to an integrated direct-buried device for building water and heating well casing based on BIM, which is especially suitable for the pre-embedding construction of pipe casings for building water supply, drainage, fire protection, heating and other pipeline systems. Background Technology

[0002] In recent years, with the acceleration of urbanization and the gradual development of high-rise buildings, people have higher and higher requirements for their living environment. The leakage of water and heating pipe wells in high-rise buildings, as well as the positioning and fixing methods of the casings, have become the main reasons restricting the installation accuracy.

[0003] Traditional pre-embedded casing for plumbing wells has the following problems:

[0004] Sleeve size deviation: The size of the sleeve depends on the size of the pipe. Building plumbing pipe wells are often relatively narrow. If the pipe and its valve components are not arranged in advance, they may not meet the specifications and usage requirements, resulting in pipe dismantling and modification.

[0005] Positioning deviation: The pre-embedded position of the casing depends on manual layout. The water and heating pipe well is subject to the accuracy of civil construction. Positioning deviation is easily caused by structural deformation or construction error, which leads to the cheap casing and the need for rework or hole hanging later, which increases costs.

[0006] Fixing method: The conventional fixing method is to nail four stators around the sleeve to fix it to the formwork, and then tie it firmly with tie wire. This method is prone to displacement due to factors such as concrete vibration, rebar tying, and construction workers stepping on it.

[0007] Potential leakage: If the casing is incorrectly embedded, the secondary hanging hole at the connection between the casing and the pipe is not tight, or the thickness of the waterproof layer is not considered, leakage may easily occur.

[0008] Low construction efficiency: Each sleeve requires four nails for fixing. High-rise buildings have numerous water and heating pipe systems, and the installation and fixing of sleeves takes a long time and is inefficient.

[0009] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a BIM-based integrated direct-buried device for building plumbing well casings. Utility Model Content

[0026] Furthermore, both sides of the threaded steel bar are welded and fixed to the horizontal plane.

[0027] Furthermore, the outer peripheral side of the sleeve contacts the horizontal surface of the threaded steel or angle steel adjacent to it, and the sleeve is welded and fixed to the horizontal surface of the threaded steel or angle steel adjacent to it to position and fix the sleeve.

[0028] Furthermore, the lower end of the sleeve is flush with the bottom surface of the outer frame, and the upper end of the sleeve is 50mm above the finished ground surface.

[0038] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0039] See Figures 1 to 3 As shown;

[0040] This embodiment discloses a BIM-based integrated direct-buried device for building plumbing well casing. The device includes an outer frame 1; multiple threaded steel bars 2 fixed inside the outer frame 1, with positioning spaces formed between adjacent threaded steel bars 2 and between the threaded steel bars 2 and the outer frame 1; and a casing 3 fixed inside the positioning space.

[0041] The adjacent sides of the outer frame 1 are constructed with a height difference to avoid interference between the transversely arranged threaded steel bars 2 and the longitudinally arranged threaded steel bars 2, and the height difference between the adjacent sides of the outer frame 1 is equal to the outer diameter of the threaded steel bars 2.

[0042] Specifically, the integrated direct-buried device in this embodiment mainly includes angle steel, threaded steel 2, and casing 3. The angle steel is welded and fixed to form the outer frame 1 of this embodiment. First, four angle steels are overlapped and welded to form a quadrilateral frame according to the perimeter of the well. The angle steel in this embodiment uses an overlap welding method, which creates a height difference through its thickness. This height difference can also be used as the height difference generated when the threaded steel 2 is overlapped, thus avoiding interference between the horizontally and vertically arranged threaded steel 2. Finally, the threaded steel 2 and the outer frame 1 are used to construct the positioning space for the casing 3 that meets the design size requirements.

[0043] Preferably, the outer frame 1 of this embodiment is welded from four angle steels; wherein, the outer frame 1 includes two first angle steels 101 extending along a first direction; and two second angle steels 102 extending along a second direction; wherein, the first direction is perpendicular to the second direction;

[0044] The first angle steel 101 is located below the second angle steel 102. The end faces of the vertical surfaces 103 of the first angle steel 101 and the second angle steel 102 are close to each other and welded together. The horizontal surface 104 of the second angle steel 102 overlaps the horizontal surface 104 of the first angle steel 101.

[0045] The outer frame 1 creates a height difference by having the second angle steel 102 overlap the first angle steel 101.

[0046] In this embodiment, the first angle steel 101 and the second angle steel 102 are arranged in an overlapping manner, with the overlapping surface being the horizontal plane, and are fixed by welding. During the overlapping and welding, welding is required in the X, Y, and Z axis directions to ensure the stability of the device, thereby forming a square frame that adapts to the perimeter of the well, and finally forming the basic outer frame of the positioning device for the casing inside the well.

[0047] The two ends of the transversely arranged threaded steel 2 overlap the horizontal plane 104 of the first angle steel 101, and the two ends of the longitudinally arranged threaded steel 2 overlap the horizontal plane 104 of the second angle steel 102.

[0048] The longitudinally arranged threaded steel bar 2 is located above the transversely arranged threaded steel bar 2, and the longitudinally arranged threaded steel bar 2 is attached to the upper end of the transversely arranged threaded steel bar 2 and welded and fixed.

[0049] Based on the overlapping form of the first angle steel 101 and the second angle steel 102, the threaded steel 2 arranged laterally and longitudinally in this embodiment also relies on this overlapping form to stagger the arrangement of the threaded steel 2, thereby avoiding interference between the threaded steel 2.

[0050] The parametric modeling in this embodiment is based on BIM software such as Revit 2020 to create a 3D model of the water supply and drainage, fire protection, heating / air conditioning pipe system of the plumbing well. Combined with the civil engineering and structural models, automatic collision detection is performed to optimize the pipe layout of the plumbing well, thereby determining the precise positioning of the sleeve in the pipe well and ensuring that the positioning error is ≤5mm. Therefore, based on this method, after the position of the sleeve is determined, the positioning space is constructed by the above-mentioned transverse threaded steel 2 and longitudinal threaded steel 2, and the corresponding sleeve 3 can be fixed.

[0051] In this embodiment, the sleeve 3 is made of steel or composite material, and its inner diameter is generally two sizes larger than the actual pipe diameter. The outer circumference of the sleeve 3 contacts the horizontal surface of the threaded steel 2 or angle steel close to it, and the sleeve 3 is welded and fixed to the horizontal surface 104 of the threaded steel 2 or angle steel close to it to position and fix the sleeve 3. The lower end of the sleeve 3 is flush with the bottom surface of the outer frame 1, and the upper end of the sleeve 3 is 50mm higher than the finished surface of the ground.

[0052] In the construction simulation, BIM software such as Fuzor2020 or Navisworks2020 is used to pre-play the later installation plan in the model, simulate the pre-embedding process of sleeve 3, ensure that the pipeline installation construction meets the specifications, and verify the feasibility of construction.

[0053] To ensure structural stability and thus indirectly ensure positioning accuracy, both sides of the threaded steel bar 2 in this embodiment are welded and fixed to the horizontal plane 104.

[0054] In the above technical solution, the integrated direct-buried device for building water and heating well casing based on BIM provided by this utility model has the following beneficial effects:

[0055] The integrated direct-buried device of this utility model consists of angle steel, threaded steel 2 and sleeve 3, which can ensure the accurate positioning of sleeve 3. The device is easy to source materials and construct, avoids secondary pouring, and ensures the quality and efficiency of sleeve installation.

[0056] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
