Description

Technical Field

[0001] This application relates to the field of pipeline connection technology, specifically a pipeline connection structure for basement roof slabs under large differential settlement. Background Technology

[0002] The construction site is a non-self-weight collapsible loess site, with a collapsibility level of I (slight) and II (moderate); a certain project requires structural measures, and the entire project is divided into 13 sections.

[0003] An existing patent (publication number: CN214574450U) discloses a design including an embedded part, a hanger, and a connecting hose. The embedded part is embedded in the basement roof slab on both sides of the settlement joint. The hanger is correspondingly located at the bottom of the embedded part and includes a hanger rod and a clamp. The hanger rod is connected to the bottom of the embedded part. The horizontal cross-section of the hanger rod is L-shaped, including a horizontal plate section and a vertical plate section. A first through hole for the basement pipe is opened at the lower part of the vertical plate section. A support plate is provided at the lower part of the hanger rod, located on the inside corner side, and the support plate supports the bottom of the basement pipe. A second through hole is opened on the support plate. The clamp is attached to the basement pipe, and the lower end of the clamp passes through the second through hole. The two ends of the connecting hose are respectively connected to the basement pipes on both sides of the settlement joint, and the connecting hose is connected to the basement pipes through flanges. The length of the connecting hose is adjustable. This utility model solves the technical problem that traditional pipes are prone to damage and leakage when passing through settlement joints.

[0004] The aforementioned connection structure, through the use of flexible hoses, solves the technical problem of pipe damage and leakage risks when traditional pipes pass through settlement joints. However, while flexible hoses are easy to install, their material and structure may lead to aging and damage during long-term use, increasing maintenance difficulty and costs. Secondly, the safety of pipes in the basement ceiling is crucial. Although flexible hoses have advantages in some aspects, they may not be able to withstand high pressure or external impacts in certain situations, posing certain safety hazards. Furthermore, when the basement pipes at both ends of the flexible hose settle, the connection point may not be at the same level, easily causing deformation of the flexible hose, reducing its flow capacity and making it prone to blockage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a basement roof slab pipe connection structure under large differential settlement, which has advantages such as adaptive adjustment support and solves the problems in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a basement roof slab pipe connection structure under large differential settlement, comprising multiple embedded parts, each embedded part having a U-shaped frame at its bottom, and each U-shaped frame having an adaptive component installed on its inner bottom wall;

[0007] Each of the aforementioned adaptive components includes a sleeve, a telescopic block, multiple ratchet blocks, a fixing plate, a pawl, a rotating rod, and a torsion spring;

[0008] Each of the telescopic blocks is fixedly connected to a support plate at its top end, and each of the support plates is provided with a clamping assembly on its upper surface.

[0009] Each of the clamping assemblies includes two clamping rings, two threaded rods, and two clamping blocks.

[0010] Through the above scheme, the adaptive components enable the embedded parts to move downwards when they sink, causing the U-shaped frame and sleeve to protrude from the sleeve and keep the pipeline in the predetermined position, achieving an adaptive effect. The pawls and ratchet blocks limit the movement of the expansion blocks, maintaining support for the pipeline and effectively preventing pipeline breakage during settlement. The threaded rods and clamping blocks effectively limit the movement of pipelines of different sizes, improving overall practicality.

[0011] Furthermore, each of the U-shaped frames has a fixing hole on its upper surface that penetrates the embedded part.

[0012] The above solution, through the setting of fixing holes, can achieve the purpose of fixing the U-shaped part to the embedded part.

[0013] Furthermore, the bottom end of each sleeve is fixedly connected to the adjacent U-shaped frame, each telescopic block is slidably inserted into the adjacent sleeve, each fixed plate is fixedly connected to the adjacent sleeve, each ratchet block is fixedly connected to the adjacent telescopic block, both ends of each rotating rod are rotatably connected to the adjacent fixed plate, and both ends of each torsion spring are fixedly connected to the adjacent fixed plate and rotating rod, respectively.

[0014] The above scheme, through the setting of ratchet blocks and pawls, can achieve the purpose of limiting the telescopic block.

[0015] Furthermore, the bottom end of each clamping ring is hinged to the support plate adjacent to it, each threaded rod is threadedly connected to the clamping ring, and each clamping block is rotatably connected to the threaded rod adjacent to it.

[0016] The above scheme, through the setting of threaded rods and clamping blocks, can achieve the purpose of fixing external pipelines.

[0017] Furthermore, each of the clamping rings has a connection hole at its top end.

[0018] The above solution, through the setting of the connecting hole, makes it easy to connect two close clamping rings using external bolts.

[0019] Furthermore, a turntable is fixedly connected to the top of each of the threaded rods.

[0020] The above solution, with the turntable, makes it easy for users to rotate the turntable to move the threaded rod.

[0021] Furthermore, the outer surface of each turntable is knurled.

[0022] The above solution, which involves knurling the outer surface of the turntable, can reduce the likelihood of the user's hand slipping.

[0023] Furthermore, a flexible pad is fixedly installed on the upper surface of each of the support plates.

[0024] The above solution, through the installation of flexible pads, can reduce wear on external pipes.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] This basement roof slab pipe connection structure under large differential settlement features an adaptive component that allows the embedded parts to move downwards when they settle, causing the U-shaped frame and sleeve to protrude from the sleeve and keep the pipe in a predetermined position, achieving an adaptive effect. The pawls and ratchet blocks limit the movement of the expansion blocks, maintaining support for the pipe and effectively preventing pipe breakage during settlement. The threaded rods and clamping blocks effectively limit pipes of different sizes, improving overall practicality. Attached Figure Description

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, a basement roof slab pipe connection structure under large differential settlement includes multiple embedded parts 1. Each embedded part 1 has a U-shaped frame 2 at its bottom. Each U-shaped frame 2 has an adaptive component 3 installed on its inner bottom wall. Each U-shaped frame 2 has a fixing hole 6 through the embedded part 1 on its upper surface. The fixing hole 6 can be used to fix the U-shaped part to the embedded part 1.

[0035] Please see Figure 1 , Figure 2 and Figure 4 Each adaptive component 3 includes a sleeve 301, a telescopic block 302, multiple ratchet blocks 303, a fixing plate 304, a pawl 305, a rotating rod 306, and a torsion spring 307;

[0036] Please see Figure 1 , Figure 3 and Figure 4 Each telescopic block 302 has a support plate 4 fixedly connected to its top end. Each support plate 4 has a flexible pad 9 fixedly installed on its upper surface. The flexible pad 9 reduces wear on external pipes. Each support plate 4 has a clamping assembly 5 on its upper surface. Each sleeve 301 has a U-shaped frame 2 fixedly connected to its bottom end. Each telescopic block 302 is slidably inserted into its sleeve 301. Each fixed plate 304 is fixedly connected to its sleeve 301. Each ratchet block 303 is fixedly connected to its telescopic block 302. Each rotating rod 306 has its two ends rotatably connected to its fixed plate 304. Each torsion spring 307 has its two ends fixedly connected to its fixed plate 304 and rotating rod 306. The ratchet block 303 and pawl 305 limit the telescopic block 302.

[0037] Please see Figure 1 , Figure 3 and Figure 4Each clamping assembly 5 includes two clamping rings 501, two threaded rods 502, and two clamping blocks 503. The bottom end of each clamping ring 501 is hinged to the support plate 4 adjacent to it. Each threaded rod 502 is threadedly connected to the clamping ring 501. Each clamping block 503 is rotatably connected to the threaded rod 502 adjacent to it. The arrangement of the threaded rods 502 and clamping blocks 503 enables the fixing of external pipes. Each clamping ring 501 has a connection hole 7 at its top end. The connection hole 7 allows for easy connection of two adjacent clamping rings 501 using external bolts. Each threaded rod 502 has a turntable 8 fixedly connected to its top end. The turntable 8 allows the user to rotate it to move the threaded rod 502. The outer surface of each turntable 8 is knurled to reduce the risk of slippage.

[0038] This embodiment presents a basement roof slab pipe connection structure under large differential settlement. Through the adaptive component 3, when the embedded part 1 settles, the embedded part 1 can drive the U-shaped frame 2 and the sleeve 301 to move downward, and the telescopic block 302 will be exposed from the sleeve 301, keeping the pipe in a predetermined position and achieving an adaptive effect. Through the pawl 305 and the ratchet block 303, the telescopic block 302 can be limited to maintain the support effect on the pipe and effectively avoid the pipe breaking under settlement. Through the threaded rod 502 and the clamping block 503, pipes of different sizes can be effectively limited, improving the overall practicality.

[0039] The working principle of the above embodiment is as follows: the embedded part 1 is connected to the basement roof slab. When the embedded part 1 is subjected to the downward moving force of settlement, the embedded part 1 drives the U-shaped frame 2 connected to it to move downward. The U-shaped frame 2 drives the fixed sleeve 301 to move downward. Since the pipeline is supported downward by other support plates 4, the pipeline height can remain unchanged. When the sleeve 301 moves downward, the telescopic block 302 moves away from the sleeve 301. At the same time, the pawl 305 does not limit the pawl block 303. After the settlement is completed, the pawl 305 limits the pawl block 303 to ensure that the telescopic block 302 does not fall with gravity, thereby achieving the continuous support effect of the pipeline and achieving the effect of adaptive adjustment.
