Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipeline installation, and relates to a compensation structure for a rainwater system pipeline passing through a structural joint. Background Art
[0002] Some existing buildings require a light and transparent spatial effect. The periphery is a whole glass curtain wall, which is supported by a windbreak truss. The size of the structural column cannot be too large and cannot be wrapped externally, and all are exposed and sprayed with fluorocarbon paint. In view of the aesthetic requirements of the building, it is required that the siphonic rainwater riser cannot be set completely exposed.
[0003] Since large-sized ring plates are provided at the floor slabs of the structural columns, the rainwater riser cannot be laid along the columns. After repeated research, it is determined that part of the siphonic rainwater riser is laid in the concrete-filled steel tube column in a concealed manner, and the other part is laid along the windbreak truss on the outside of the building, in the patio or courtyard.
[0004] A structural joint refers to the general term for expansion joints, settlement joints, seismic joints, etc. provided between two adjacent buildings or two parts of a building to avoid temperature expansion and contraction, foundation settlement, earthquake collision, etc. When installing the siphonic rainwater pipe, it is inevitable to pass through the expansion joint. When passing through the heat medium, thermal elongation of the pipeline will occur and deformation will be generated. Since the pipeline is a flexible structure, it will return to its original position after cooling. Therefore, a relatively stable structure is required to achieve compensation at the deformation position and avoid hard connection caused by limiting, resulting in damage to the pipeline and difficulty in resetting.
[0005] In summary, a compensation structure for a rainwater system pipeline passing through a structural joint of the present utility model is proposed. Summary of the Invention

A vertical guide plate is installed in the vertical part located in the frame body, and a guide groove is formed on the side of the vertical guide plate opposite to the telescopic rod. The contact roller is installed in the guide groove.
[0014] In a further technical solution, the telescopic rod includes an inner column and an outer cylinder. The inner column is installed in the outer cylinder, and a sealing plate is installed at the end of the inner column in the outer cylinder.
[0015] A connecting spring is also installed in the outer cylinder. The two ends of the connecting spring are respectively fixedly connected to the inner wall of the outer cylinder and the sealing plate.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0035] The application principle of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0036] Embodiment 1
[0037] As Figures 1-5 shown, it is an implementation solution of the present utility model, a compensation structure for a rainwater system pipeline passing through a structural joint, including a basement roof structure 1, and a drainage gutter 2 is arranged at the basement roof structure 1; a structural joint 6 is arranged at the bottom of the drainage gutter 2;
[0038] including a rainwater pipe 4, the rainwater pipe 4 is communicated with the bottom of the drainage gutter 2, and a debris guard 3 is installed at the top of the rainwater pipe 4;
[0039] The rainwater pipe 4 includes a horizontal part 41 and a vertical part 42, the horizontal part 41 horizontally penetrates through the structural joint 6, and a double-hinged expansion joint 5 is installed at the horizontal position where the rainwater pipe 4 passes through the structural joint 6; there are two groups of vertical parts 42 and they are respectively connected to both ends of the horizontal part 41 through arc-shaped pipe orifices 43; a limiting member 7 is installed on the vertical part 42 located below the horizontal part 41, and a fixed support 9 is installed at the bottom.
[0040] In a further technical solution, the double-hinged expansion joint 5 includes a connecting ring one 51 and a connecting ring two 52, the connecting ring one 51 and the connecting ring two 52 are respectively fixedly connected to the horizontal part 41 and the corresponding arc-shaped pipe orifice 43, and are located on both sides of the structural joint 6;
[0041] A corrugated pipe 53 and a connecting member are connected between a first connecting ring 51 and a second connecting ring 52. The two ends of the corrugated pipe 53 are fixedly connected to the first connecting ring 51 and the second connecting ring 52 respectively, and the connecting member is adapted to be connected to the outside of the corrugated pipe 53.
[0042] In a further technical solution, the connecting member includes a hinge seat 54. The hinge seats 54 are symmetrically arranged between the first connecting ring 51 and the second connecting ring 52. A first rod 55 is rotatably connected to the hinge seat 54, and the two groups of first rods 55 are rotatably connected to each other. An external shape 8 is also installed outside the basement roof structure 1.
[0043] Operation method:
[0044] First step, before the construction of the rainwater pipe 4, first prepare materials according to this design, check the installation position and the dimensions of the drawings, hang a line and install the fixed bracket 9 and the fasteners of the rainwater pipe 4.
[0045] Second step, install the rainwater pipe 4 in the drainage gutter 2 of the basement roof structure 1, and set a debris screen 3 on the top of the rainwater pipe 4 in the drainage gutter 2.
[0046] Third step, assemble the rainwater pipe 4 pipeline system in the factory or on-site. A double-hinged expansion joint 5 is installed in the horizontal direction of the rainwater pipe 4 at the turn (i.e., at the structural joint of the pipeline). The double-hinged expansion joint 5 bears the pressure thrust generated in the intermediate pipe connecting the two expansion joints and in the system. The double-hinged expansion joint 5 greatly enhances its own displacement capacity through cold tightening. Its compensation force meets the expansion and contraction requirements of the pipeline at the structural joint.
[0047] The schematic diagram of the expansion and contraction deformation shows the displacement schematic diagram 6 in Figure 1. For horizontal expansion and contraction, the lower part of the rainwater pipe 4 displaces along the lower part of the position-limiting member 7.

Since then, the compensation system for the rainwater system pipeline passing through the structural joint is installed.
[0050] Sixth step, carefully check each fixed bracket 9 to ensure that the pipeline system is firm and reliable. After debugging, conduct a water passing test, and it can be used after passing the test.

One is to check the flow rate operation condition of all siphonic rainwater inlets in the system and review the minimum negative pressure of the system. The other is when there is a possibility of blockage of the siphonic rainwater inlet in the place where the siphonic rainwater system is set, it should be calculated according to the operation condition that any one siphonic rainwater inlet fails and its design flow rate is evenly distributed to other rainwater inlets of the system, and review the minimum negative pressure value of the system and the water accumulation depth of the gutter (or roof). Set the number and size of the overflow ports according to the calculation results.
