Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a pre-embedded sleeve positioning support device. Background Technology

[0002] Pre-embedded pipe sleeves are a type of pipe system that is pre-installed in concrete, walls, or underground before building construction or decoration. They are mainly used to protect pipes, facilitate subsequent installation and maintenance, and meet the requirements for accurate pipe installation and structural positioning.

[0003] Pre-embedded sleeves are widely used in industrial and civil building and structural engineering projects. However, during concrete pouring and other processes, pre-embedded sleeves are susceptible to displacement or deformation due to external forces, leading to a series of negative consequences: difficulties in pipe installation, increased risk of leakage, weakened structural strength, reduced local load-bearing capacity, and problems such as backflow. Displacement or deformation of pre-embedded sleeves requires repair by damaging the wall, resulting in complex maintenance and high costs.

[0004] Traditional methods of positioning and supporting embedded sleeves involve adding additional steel bars around the sleeve for fixation. During concrete pouring, the impact of the concrete on the embedded sleeve or the additional steel bars can cause displacement and deformation of the sleeve. Therefore, it is essential to improve and enhance the construction of embedded sleeves in building engineering to ensure accurate positioning, elevation, and orientation of the embedded sleeves, while also ensuring simple control methods, quick installation, and high control precision. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a pre-embedded sleeve positioning support device that is simple to install, easy to operate, can improve the accuracy of pre-embedded sleeves, and can reduce construction costs and shorten the construction period.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A pre-embedded sleeve positioning support device includes a square positioning support and a continuous threaded rod arranged parallel to the outer sides of the four corners of the square positioning support. The length of the continuous threaded rod is greater than the length of the sleeve, and the outer diameter of the continuous threaded rod is tangent to the inner diameter of the sleeve. The square positioning support includes a second positioning support arranged in the middle plane of the sleeve, a first positioning support and a third positioning support arranged in the inner sides of both ends of the sleeve, and the first positioning support, the second positioning support and the third positioning support are arranged in parallel.

[0008] A further improvement of this utility model's technical solution lies in that: the through-length screw adopts a φ...

[0009] The 14mm HPB300 round steel bar is 400mm longer than the sleeve, and the length of the continuous screw extending out of the sleeve at both ends is 200mm.

[0010] A further improvement of this utility model is that the square positioning support is welded from the ends of four equal-length φ14mm HPB300 round steel bars; the side length of the square is:

[0011]

[0012] Where d is the inner diameter of the sleeve and φ is the diameter of the through screw.

[0013] A further improvement of this utility model is that the first positioning support and the third positioning support are located 150mm inward from both ends of the sleeve.

[0014] A further improvement to the technical solution of this utility model is that the apex of each continuous screw and the square positioning support is machine welded.

[0015] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0016] This utility model uses a three-dimensional grid structure positioning support, which is welded from a continuous screw and a square positioning support machine, to replace the traditional method of adding additional steel bars around the pre-embedded sleeve for fixing. During construction, the position, support, and elevation of the pre-embedded sleeve are controlled. This pre-embedded sleeve positioning support device is easy and quick to install, has high control accuracy, avoids the sleeve from shifting due to external forces, ensures the accuracy of the pipeline crossing position, and reduces construction costs.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0022] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] like Figure 1 As shown, a pre-embedded sleeve positioning support device utilizes leftover φ14mm HPB300 steel bars to fabricate a continuous threaded rod 1. The length of the threaded rod is:

[0025] L = L1 + L2, L2 = 400mm

[0026] The sleeve length L1 is determined by the engineering design documents;

[0027] Four equal-length φ14mm HPB300 round steel bars are welded at their ends to form a square positioning support 2, where α=90°, and the side length of the square is:

[0028]

[0029] Where d is the inner diameter of the casing and φ is the diameter of the through screw; the four through screws 1 are machine-welded to the vertices of the three square positioning supports 2 to form a three-dimensional grid frame structure positioning support. The four through screws 1 and the three square positioning supports 2 are set in parallel, and the through screws 1 and the square positioning supports 2 are set in perpendicular.

[0030] The positioning support of the three-dimensional grid frame structure passes through the interior of the pre-embedded sleeve 3. The second positioning support 2-2 is located in the middle plane of the sleeve 3. The first positioning support 2-1 and the third positioning support 2-3 are located 150mm inward from both ends of the sleeve. The two ends of the through screw 1 extend 200mm out of the sleeve and form a rigid connection with the outer frame of the template.

[0031] In summary, this utility model of pre-embedded sleeve positioning support device uses a three-dimensional grid structure positioning support made of a continuous screw and a square positioning support machine welded together to replace the traditional method of adding additional steel bars around the pre-embedded sleeve for fixing. During construction, the position, support, and elevation of the pre-embedded sleeve are controlled. This pre-embedded sleeve positioning support device is easy and quick to install, has high control accuracy, avoids the sleeve from shifting due to external forces, ensures the accuracy of the pipeline crossing position, and reduces construction costs.
