Description

Technical Field

[0001] The present application belongs to the technical field of auxiliary tooling for construction, and specifically relates to a pipe groove reservation device. Background Art

[0002] During residential wall construction, water pipes need to be laid inside the walls, so pipe grooves must be reserved inside the walls. Currently, a common method for preserving pipe grooves is to add water pipe grooves to the casting formwork. Compared to directly grooving the wall after casting, grooving effectively protects the building's overall structure and avoids cutting into the building's structural reinforcement during the grooving process.

[0003] However, in the actual construction process, due to the limited load-bearing capacity of the bolts connecting the water pipe trough and the formwork, the repeated use and tightening capacity are reduced, and the water pipe trough is in the form of multiple sections. Under the radial load applied by the concrete during the pouring process, part of the water pipe trough often becomes loose and deformed, causing concrete to leak between the water pipe trough and the formwork, resulting in poor pipe trough forming quality and difficulty in removing the formwork. Summary of the Invention

[0004] The present application provides a pipe groove reservation device, which aims to solve the problem that water pipe grooves are easily loosened and damaged during the existing residential construction process, resulting in poor pipe groove forming quality.

[0008] In an optional solution, the first folded edge is fixed to the connecting leg by welding; the first folded edge is disconnected from the center, so that the connecting portion forms two mutually symmetrical structural parts;

[0009] There is an avoidance space between the two sections of the first folded edge and the end faces of the connecting legs on both sides, and the end faces of the connecting legs are higher than the sections of each first folded edge; the avoidance position is defined as the first welding position, and the abutment position between the end edge of the trough body shaping arc plate and the outer side surface of the first folded edge is defined as the second welding position.

[0010] In an optional solution, the first folded edge is fixed to the connecting leg by assembly; a plurality of assembly holes are opened on the first folded edge;

[0011] During assembly, the nut portion of the fastener is installed into the central cavity of the pressing groove portion, and the screw rod of the fastener is passed through the interval between the two connecting legs and into the assembly hole for assembly and fastening.

[0012] In an optional solution, the grooved portion is formed by splicing together a number of identical structural segments, one end of the grooved portion is provided with an inwardly extending insertion groove, and the other end of the grooved portion is extended outwardly to form an insertion tenon.

[0034] In order to solve the problem that water pipe grooves are easily loosened and damaged during existing residential construction, resulting in poor pipe groove forming quality, the present application provides a pipe groove reservation device, and the specific embodiments are as follows:

[0035] In one embodiment, see Figure 1 and Figure 2 The present application provides a pipe groove reservation device, including a groove pressing part 1 and a connecting part 2.

[0036] In this embodiment, the trough pressing part 1 includes a trough body shaping arc plate 11, a connecting leg 12, and an inner support 13. The trough body shaping arc plate 11 is semicircular, and the inner side surface of the trough body shaping arc plate 11 is aligned with the outer end surface of the water supply pipe, or the inner diameter of the trough body shaping arc plate 11 is slightly larger than the diameter of the water supply pipe, ensuring that the water supply pipe can be smoothly placed in the cast pipe trough.

[0037] In this embodiment, the connecting feet 12 are constructed by extending from both ends of the trough body shaping arc plate 11 toward the center, and the connecting feet 12 at both ends are on the same horizontal plane; the internal support 13 is located in the central cavity formed by the trough body shaping arc plate 11 and the connecting feet 12, providing support for the trough body shaping arc plate 11 and ensuring the structural strength of the trough pressing part 1.

[0038] In this embodiment, the connecting portion 2 includes a first folded edge 21 and a second folded edge 22, and two second folded edges 22 are symmetrically arranged; the two ends of the first folded edge 21 are integrally formed with the second folded edge 22 and are perpendicular to each other. The outer side surface of the first folded edge 21 is fixedly connected to the bottom surface of the connecting leg 12. The connecting leg 12 is bent inward by the groove body shaping arc plate 11 to ensure the flatness of the connecting surface between the groove portion 1 and the connecting portion 2, and to prevent the connecting leg 12 from bending outward, resulting in excess grooves left in the wall after casting, which affects the appearance; the second folded edge 22 is provided with a plurality of through holes, which can be connected to the casting template 5 with the help of assembly parts such as pins, making the pipe groove reservation device flexible to use and well-applicable.

[0039] Therefore, the present application combines the grooving part 1 and the connecting part 2 of the pipe groove reservation device into one body, uses the grooving part 1 to reserve the pipe groove for casting, and uses the connecting part 2 to directly assemble and connect with the casting template 5, thereby reserving a flat pipe groove without affecting the overall structure of the building, avoiding the problem of loosening and damage of the water pipe groove during the casting process caused by assembling the water pipe groove by bolts, resulting in poor pipe groove forming quality. The pipe groove forming quality is good, and the pipe groove reservation device and the casting template 5 are easy to disassemble and assemble.

[0040] In one embodiment, see Figure 2 The first folded edge 21 is fixed to the connecting leg 12 by welding. The first folded edge 21 is disconnected from the center, so that the connecting portion 2 forms two mutually symmetrical structural parts. Specifically, the connecting portion 2 can be directly divided and made using existing template profiles.

[0041] In this embodiment, an escape space is left between the two cross sections of the first folded edge 21 and the end surfaces of the connecting legs 12 on both sides, and the end surfaces of the connecting legs 12 are higher than the cross sections of each first folded edge 21. This escape space is defined as the first welding position 3, and the position where the end edge of the trough body shaping arc plate 11 abuts the outer surface of the first folded edge 21 is defined as the second welding position 4. That is, through the welding operation of the first welding position 3 and the second welding position 4, both ends of the connecting leg 12 are connected and fixed to the first folded edge 21, making the device integrated and having good structural strength, avoiding the loosening or falling off of the groove pressing part 1 affecting the forming quality of the pipe groove, and both the first welding position 3 and the second welding position 4 have sufficient welding operation space, and the device is easy to process.

[0042] In one embodiment, see Figure 3 The first folded edge 21 is fixed to the connecting leg 12 by assembly. The connecting portion 2 can directly use an existing template profile with a plurality of assembly holes opened on the first folded edge 21.

[0043] During assembly, the nut portion of the fastener is slid into the central cavity of the groove portion 1 from both ends or directly installed through the gap between the connecting legs 12, and the bottom surface of the connecting leg 12 is abutted against the outer surface of the first folded edge 21 to complete the fitting of the groove portion 1 and the connecting portion 2. At the same time, the screw portion of the fastener is passed through the gap between the two connecting legs 12 and into the corresponding assembly hole on the first folded edge 21 for assembly and tightening. The compression force between the fastener nut and the connecting legs 12 and the compression force between the nut and the first folded edge 21 is used to achieve the compression and fixation of the groove portion 1 and the connecting portion 2. Assembly is convenient and processing costs can also be reduced.

[0044] In one embodiment, the groove portion 1 is formed by splicing together several identical structural segments. One end of the groove portion 1 is provided with an inward insertion groove, and the other end of the groove portion 1 is provided with an outward extension with a splicing tenon. This splicing combination facilitates the device's adaptation to different wall heights, providing greater applicability.

[0045] In one embodiment, see Figure 4 The inner support 13 includes a first support plate 131 and a second support plate 132. Among them, two first support plates 131 are symmetrically arranged, and the two ends of the first support plate 131 are respectively fixedly connected to the inner side surface of the trough body shaping arc plate 11 and the top surface of the connecting foot 12; the two ends of the second support plate 132 are respectively fixedly connected to the middle section of the first support plate 131 on both sides. Specifically, the first support plate 131 is perpendicular to the connecting foot 12 or the inner angle between the first support plate 131 and the connecting foot 12 is an acute angle. By increasing the connection and fixing position of the trough body shaping arc plate 11 and the connecting foot 12 through the first support plate 131 and the second support plate 132, the integrity of the groove pressing part 1 is stronger and the structure is more stable.

[0046] Furthermore, the inner support 13 is detachably fixedly connected to the inner side surface of the groove body shaping arc plate 11 and the top surface of the connecting foot 12 by limiting the contact therewith through the first support plate 131, thereby enabling the processing and manufacturing of the groove pressing part 1 to be completed by sheet metal bending, welding, etc., thereby avoiding the high processing cost of the one-piece molding processing method.

[0047] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.

[0048] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
