Description

Technical Field

[0001] This article relates to modular building pipeline integrated pre-embedded devices. Background Technology

[0002] Modular construction, as an efficient and environmentally friendly building form, significantly shortens the construction cycle through factory prefabrication and on-site assembly, and has been widely used in residential and commercial buildings in recent years. However, the pipeline layout of existing modular buildings still has significant shortcomings:

[0003] 1. Exposed pipelines are a prominent issue: In order to simplify construction, most modular buildings adopt the design of exposed pipelines, with water pipes, electrical conduits, etc. directly exposed on the wall surface or under the ceiling. This not only damages the overall aesthetics of the building, but also makes the pipelines prone to wear and tear due to collisions and friction.

[0004] 2. Insufficient pipeline protection: Exposed pipelines are subject to long-term environmental factors (such as humidity, temperature changes, and dust accumulation), resulting in a significantly shortened service life. For example, exposed high-voltage electrical conduits are prone to short circuits due to rainwater seepage, while exposed low-voltage electrical conduits are susceptible to electromagnetic interference affecting signal transmission.

[0005] 3. High maintenance difficulty: Exposed pipelines are mixed with the building's decorative layer, and the decorative structure needs to be disassembled during maintenance, which not only increases maintenance costs but may also cause secondary damage to the building modules.

[0006] In existing technologies, although some pre-embedded solutions attempt to hide pipelines inside the wall, most of them adopt the method of simultaneous pipe embedding during on-site pouring, which has the following problems: First, the accuracy of the pre-embedded position is low, and the pipeline is easily damaged due to the displacement of the concrete pouring; second, the prefabrication of modules and the pre-embedded pipeline are disconnected, and on-site adjustment is difficult; third, the connection strength between the pipeline and the building structure is insufficient, and it is easy to loosen after long-term use.

[0007] Therefore, there is an urgent need for a device that can achieve integrated pre-embedding of pipelines, balance installation strength and aesthetics, and adapt to the prefabrication characteristics of modular buildings, in order to solve the above-mentioned technical defects. Utility Model Content

[0008] This utility model aims to provide a modular building pipeline integrated pre-embedded device, effectively solving the problems of poor aesthetics, easy damage, and difficult maintenance caused by exposed modular building pipelines. It also overcomes the poor adaptability of traditional pre-embedded solutions, providing a modular building pipeline integrated pre-embedded device. The specific solution is as follows:

[0009] A modular building pipeline integrated pre-embedded device includes a prefabricated cover plate and a base plate, with a pipe groove area formed between the cover plate and the base plate, the pipe groove being used to install pre-embedded pipe fittings;

[0010] The base plate has multiple pre-embedded rivets inside, and the cover plate has mounting holes at corresponding positions. The rivet includes a mounting plate, and the surface of the mounting plate has two L-shaped bent plates pre-embedded inside the base plate. The straight edge of the L-shaped bent plate is connected to the mounting plate in a perpendicular direction, and the bent edge of the L-shaped bent plate is parallel to the mounting plate. The surface of the bent edge is provided with a threaded tube, and the threaded tube is provided with internal threads.

[0011] The bottom of the threaded tube is connected to the bent edge, and a gap is provided between the top of the threaded tube and the surface of the mounting plate. The initial included angle between the straight edge of the L-shaped bent plate and the mounting plate is 95°-105°. After the bolts are tightened, the included angle is reduced to 85°-95°, and the maximum deformation of the straight edge does not exceed 10°. Through the existence of the gap and angle, when the bolts are tightened, the L-shaped bent plate is driven to undergo a small-angle bending deformation, so that the cover plate and the base plate are firmly connected.

[0012] To ensure the stability of the connection between the cover plate and the base plate, 4-8 rivets are used, evenly distributed along the edge of the base plate, with a spacing of more than 300mm between adjacent rivets. This distribution ensures uniform stress distribution and prevents excessive local stress from causing deformation of the cover plate or base plate.

[0013] Furthermore, the L-shaped bend plate is made of spring steel with a thickness of 1-5mm, and the length of the straight edge is 40-60mm to ensure the anchorage depth between the L-shaped bend plate and the base concrete, preventing the tie rods from coming out of the base plate; the bend length is set to 20-40mm to provide a stable installation foundation for the threaded pipe, and the elastic restoring force enhances the clamping force between the bolt and the threaded pipe, improving the connection strength.

[0014] Furthermore, a buffer pad is provided on the side of the cover plate facing the pipe groove. The buffer pad is made of rubber or closed-cell foam with a thickness of 2-5mm. The surface of the buffer pad is provided with an arc-shaped groove that is compatible with the pre-embedded pipe fitting, which can limit the pipeline and prevent displacement.

[0015] Furthermore, both the base plate and the cover plate are made of precast concrete and have internal steel mesh reinforcement, which effectively enhances the structural strength and meets the load-bearing requirements of modular buildings.

[0016] Beneficial effects:

[0017] During installation, first place the water pipes, power pipes, and low-voltage pipes that need to be pre-buried into the pipe groove, and then put the cover plate on the upper surface of the base plate, ensuring that the mounting holes of the cover plate correspond to the through holes of the base plate tie rods.

[0018] Then, multiple bolts are sequentially passed through the mounting holes and through-holes to connect with the threaded pipe. When the bolts are tightened, the L-shaped bending plate will bend at a small angle, causing the bolts and tie rods to connect tightly, thereby fixing the cover plate to the base plate, ensuring that the device has a certain installation strength, realizing the concealed pre-embedding of pipelines, and solving the problem of exposed pipelines in existing modular buildings.

[0024] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0025] Example 1:

[0026] like Figure 1-4 As shown, a modular building pipeline integrated pre-embedded device is applied to residential bathroom or kitchen modules, and its specific structure is as follows:

[0027] Base plate 2: Made of C30 precast concrete, with dimensions of 1200mm×600mm×80mm, and has Φ6mm steel mesh inside.

[0028] There are four rivet components, two on each side of the long side of the base plate 2. Mounting plate 4 is made of Q235 steel, 4mm thick, 80mm x 50mm in size, with a 2mm radius corner radius; through hole 5 has a diameter of 9mm. L-shaped bent plate 6 is made of 65Mn spring steel, 1.5mm thick, with a straight edge length of 50mm, a bent edge length of 30mm, and an initial included angle of 90°; threaded pipe 7 is M8 specification, 20mm long, and welded to the bent edge.

[0029] The cover plate 1 and the base plate 2 are made of the same material, have the same length and width, and are 50mm thick. The mounting hole 3 has a diameter of 10mm and is opened at the position of the rivet. The side of the cover plate 1 facing the pipe groove 8 is provided with a 3mm thick nitrile rubber buffer pad, and the surface is provided with an arc-shaped groove that is compatible with DN20 water pipe, PVC25 power pipe and Φ20 low voltage pipe.

[0030] Installation steps:

[0031] When the base plate 2 is prefabricated in the factory, the tie rods are embedded in the concrete to ensure that the mounting plate 4 is flush with the surface of the base plate 2 and the threaded pipe 7 faces the outside of the pipe groove.

[0032] Before the modules are assembled on site, DN20 PPR water pipes, PVC25 high-voltage conduits, and Φ20 low-voltage corrugated pipes are placed into the three sub-slots of pipe trench 8, with maintenance length reserved at the pipe joints.

[0033] Fasten the cover plate 1 onto the base plate 2, aligning the mounting hole 3 with the through hole 5 of the rivet. Use an M8×30 ​​bolt to pass through the mounting hole 3 and through hole 5 in sequence, and screw it onto the threaded pipe 7. When tightening the bolt, the bent edge of the L-shaped bent plate 6 bends about 4° toward the mounting plate 4, reducing the included angle to 86°. The pre-tightening force generated by the deformation secures the cover plate 1 to the base plate 2.

[0034] After installation, check the unobstructed flow of pipelines and the sealing of the cover.

[0035] Effect verification:

[0036] Connection strength: Tested using a tensile testing machine, the tensile strength of a single bolt reaches 6.2kN, meeting the seismic requirements of modular buildings;

[0037] Pipeline protection: After high and low temperature cycle testing from -20℃ to 60℃, the pipelines in the pipe trench showed no cracking or aging, while the exposed pipelines showed two cracks during the same test.

[0038] Ease of maintenance: It only takes 3 minutes to remove 4 bolts, which can fully expose the pipeline, improving maintenance efficiency by 4 times compared to traditional exposed pipelines.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
