Description

Technical Field

[0001] This utility model relates to the field of fire protection engineering equipment technology, specifically a pipe pre-embedding device for fire protection engineering construction. Background Technology

[0002] In fire protection engineering construction, pipeline pre-laying is a core link to ensure the stable operation of the subsequent fire protection system. Its installation accuracy and adaptability directly affect the project quality and later maintenance efficiency.

[0003] Existing pipe embedding devices used in fire protection engineering construction have limited ability to adjust pipe length. These devices use bolts for rigid fixing, requiring repeated disassembly and tightening for adjustment, which is cumbersome and makes it difficult to accurately control the fixed position. Although the devices have a certain length adjustment function, the adjustment range is narrow and cannot meet the pre-embedded length requirements of fire protection pipes on different floors and in different apartment types. Especially in complex building structures, the problem of pipes being reserved too long or too short is prone to occur, leading to later cutting or splicing and increasing the risk of leakage. Therefore, they do not meet the existing needs, and we propose a new pipe embedding device for fire protection engineering construction. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe pre-embedding device for fire protection engineering construction, so as to solve the problem that the existing pipe pre-embedding devices for fire protection engineering construction mentioned in the background art have limited ability to adjust the pipe length. The device uses bolts for rigid fixation, which requires repeated disassembly and tightening during adjustment. The operation is cumbersome and it is difficult to accurately control the fixed position. Although the device has a certain length adjustment function, the adjustment range is narrow and cannot meet the pre-embedding length requirements of fire protection pipes of different floors and different apartment types. Especially in complex building structures, it is easy to have the problem of the pipe being reserved too long or too short, which leads to problems of later cutting or connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe pre-embedding device for fire protection engineering construction, comprising a base, with screw holes penetrating through the four corners of the base, a pipe groove penetrating through the middle of the top of the base, a pipe fixedly installed in the pipe groove, a first arc-shaped locking block symmetrically provided on one side of the top of the base, and the first arc-shaped locking block fixing one end of the pipe, the bottom ends of the two first arc-shaped locking blocks being fixedly connected to the first connecting blocks, the bottom ends of the first connecting blocks being provided with multiple first tension springs, the bottom ends of the first tension springs being fixedly connected to the inner wall of the base, and a second arc-shaped locking block symmetrically provided on the other side of the top of the base through an adjustment device, and the other end of the pipe being fixed by the second arc-shaped locking block.

[0006] Preferably, a second connecting block is fixedly provided at the bottom end of the second arc-shaped block, and a plurality of second tension springs are provided at the bottom end of the second connecting block. A movable plate is fixedly connected to the bottom end of the second tension springs. A groove is provided through one side of the base, and the movable plate is slidably connected to the bottom end of the groove and fixed by an adjustment device.

[0007] Preferably, the adjusting device includes a handle, a fixing rod, a spring, a locking block, and a locking groove. One end of the moving plate is fixedly provided with a spring, and the other end of the spring is fixedly connected to the locking block. A fixing rod is fixedly provided in the middle of the top of the locking block, which is inside the spring and passes through the moving plate. A handle is fixedly provided at the top of the fixing rod. Multiple locking grooves are provided through one side of the base. The locking grooves are serrated, and the locking block is engaged with one of the locking grooves.

[0008] Preferably, the bottom of the inner wall of the groove is symmetrically provided with T-shaped grooves, and the bottom of the movable plate is symmetrically fixed with T-shaped blocks. The T-shaped blocks are slidably connected in the T-shaped grooves, and the movable plate is slidably connected to the T-shaped grooves of the groove through the T-shaped blocks.

[0009] Preferably, when the locking block is engaged with one of the slots on the base, the spring is not compressed, and the second arc-shaped locking block fixes the other end of the pipe. When the locking block is not engaged with one of the slots on the base, the spring is compressed, and the second arc-shaped locking block slides in the T-slot of the groove in the base through the T-block of the moving plate.

[0010] Preferably, both the first arc-shaped card block and the second arc-shaped card block are provided with anti-slip rubber pads on their surfaces.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes the elastic extension and contraction characteristics of the first and second tension springs to allow the base to automatically adapt to and clamp fire-fighting pipes of different diameters, eliminating the need for frequent replacement of special fasteners. This saves on accessory costs and reduces the time spent changing tools during construction, making it particularly suitable for scenarios where multiple pipe diameters need to be pre-embedded in the same project.

[0013] 2. This utility model drives the second arc-shaped locking block to move through the adjustment device, and the fixed spacing can be freely adjusted according to the actual length of the pre-buried pipe, ensuring that the two ends and the middle of the pipe of different lengths can be stably supported, avoiding unstable fixing due to the pipe being too long or too short, and reducing the risk of pipe displacement and leakage in the later stage.

[0014] 3. This utility model provides a continuous and uniform clamping force through the first and second tension springs. Combined with the contact design between the surfaces of the first and second arc-shaped clamping blocks and the pipe surface, it can increase the contact area, avoid damage to the pipe due to excessive local pressure, and ensure that the pipe maintains accurate position in subsequent processes such as concrete pouring, thus guaranteeing the final function of the fire protection system.

[0022] The adjusting device 8 includes a handle 801, a fixing rod 802, a spring 803, a locking block 804, and a locking groove 805. One end of the moving plate 16 is fixedly provided with the spring 803, and the other end of the spring 803 is fixedly connected to the locking block 804. The fixing rod 802, which is inside the spring 803 and passes through the moving plate 16, is fixedly provided at the middle position of the top of the locking block 804. The top of the fixing rod 802 is fixedly provided with the handle 801. A plurality of locking grooves 805 are provided through one side of the base 1. The locking grooves 805 are serrated, and the locking block 804 is engaged in one of the locking grooves 805.

[0023] T-shaped grooves 12 are symmetrically provided through the bottom of the inner wall of the groove 9, and T-shaped blocks 13 are symmetrically fixed at the bottom of the movable plate 16. The T-shaped blocks 13 are slidably connected in the T-shaped grooves 12, and the movable plate 16 is slidably connected to the T-shaped grooves 12 of the groove 9 through the T-shaped blocks 13.

[0024] When the locking block 804 is engaged with one of the slots 805 on the base 1, the spring 803 is not compressed, and the second arc-shaped locking block 4 fixes the other end of the pipe 7. When the locking block 804 is not engaged with one of the slots 805 on the base 1, the spring 803 is compressed, and the second arc-shaped locking block 4 slides on the T-slot 12 of the groove 9 of the base 1 via the T-block 13 of the moving plate 16.

The moving plate 16 is slidably connected to the T-groove 12 of the groove 9 through the T-shaped block 13. When it reaches the appropriate position, the handle 801 is released. At this time, the spring 803 returns to its original state and drives the fixed rod 802 to move. The locking block 804 at the bottom of the fixed rod 802 is engaged with one of the locking grooves on the base 1. At this time, the second tension spring 11 pulls the second connecting block 10 to make the second arc-shaped locking block 4 tightly fit against the other end of the pipe 7 and fix it.
