In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] Reference Figure 1-4 The present embodiment provides a seismic node bracket of a reinforced concrete structure, which includes: a bottom support seat 1, an adjustable pipe clamp 4, a main hanging assembly 5 and a side hanging assembly. The adjustable pipe clamp 4, the main hanging assembly 5 and the side hanging assembly are all arranged on the bottom support seat 1. The radial size of the adjustable pipe clamp 4 is adjustable, and its position on the bottom support seat 1 is also adjustable; the main hanging assembly 5 is vertically arranged on the outside of the adjustable pipe clamp 4, and is used to suspend and fix the bottom support seat 1; the side hanging assembly is obliquely arranged on the outside of the main hanging assembly 5, and the bottom end is movably connected to the bottom support seat 1, cooperating with the main hanging assembly 5 to suspend and fix the bottom support seat 1.

[0036] The bottom support seat 1 can be constructed by common channel steel, and a positioning hole 11 is opened on the side wall of the channel steel. There are several positioning holes 11 distributed along the length direction of the bottom support seat 1. A connecting hole 31 is constructed on the adjustable pipe clamp 4, and the connecting hole 31 and the positioning hole 11 are constructed in the same direction. The positioning pin 2 is inserted into the connecting hole 31 and the positioning hole 11 to fix the position of the adjustable pipe clamp 4 on the bottom support seat 1. After the positioning pin 2 is removed, the adjustable pipe clamp 4 can be slid along the length direction of the bottom support seat 1 to change its position on the bottom support seat 1.

[0037] In order to improve the smoothness and stability of the position adjustment of the adjustable pipe clamp 4, a slider 3 can be constructed at the bottom of the adjustable pipe clamp 4, the side wall of the slider 3 abuts the inner wall or outer wall of the bottom support seat 1 (channel steel), the connecting hole 31 is constructed on the slider 3, and the positioning pin 2 is penetrated through the connecting hole 31.

[0038] The adjustable pipe clamp 4 includes a bottom plate 41, a pipe support 42 and a U-shaped hoop 43. The pipe support 42 is arranged on the bottom plate 41, and its top surface is arc-shaped to match the outer wall shape of the supported pipe. The opening of the U-shaped hoop 43 faces the pipe support 42, and its two ends are respectively arranged on both sides of the pipe support 42, and pass through the bottom plate 41 and are fixed by the positioning pin 2 44. By adjusting the length of the two ends of the U-shaped hoop 43 passing through the bottom plate 41, the size of the annular area surrounded by the U-shaped hoop 43 and the pipe support 42 can be changed to clamp and fix pipes of different radial sizes.

[0039] During implementation, two positioning holes 431 can be respectively configured at both ends of the U-shaped hoop 43. There are several two positioning holes 431 distributed along the height direction of the adjustable pipe clamp 4 (that is, the extension direction of the end of the U-shaped hoop 43). A two connecting holes 411 are configured on the bottom plate 41. After the two ends of the U-shaped hoop 43 pass through different two connecting holes 411, they are fixed by two positioning pins 44 penetrated in the two positioning holes 431. The two positioning pins 44 can be configured only below the bottom plate 41, or they can be configured above and below the bottom plate 41. Each two positioning pins 44 can be penetrated only in the two positioning holes 431 at one end of the U-shaped hoop 43, or they can be penetrated in the two positioning holes 431 at both ends of the U-shaped hoop 43. The above implementation methods can be determined by technicians in this field during construction, and no more specific restrictions are made here. In order to improve the fixing effect on the pipeline, there should be at least two U-shaped hoops 43 distributed along the axial direction of the pipe support 42.

[0040] The above-mentioned positioning pin 1 2, positioning pin 2 44, etc. can all be selected from common components in the art such as bolts that can be movable after loosening and can be fixed after tightening.

[0041] The main suspension assembly 5 includes a main suspension rod 51, an anchor bolt 52 and a connecting bolt 53. The main suspension rod 51 is vertically arranged; the connecting bolt 53 is arranged at the bottom end of the main suspension rod 51 for connecting to the bottom support 1; the anchor bolt 52 is arranged at the top end of the main suspension rod 51 for connecting to the main building to anchor the earthquake-resistant node bracket. In order to improve the fixing effect on the pipeline, the main suspension assembly 5 should be provided with at least one set on both sides of the adjustable pipe clamp 4.

[0042] The side hanging assembly includes an X-direction side hanging assembly 6 and a Y-direction side hanging assembly 7. The X-direction side hanging assembly 6 is respectively constructed at the two ends of the length direction of the bottom support seat 1, and the Y-direction side hanging assembly 7 is respectively constructed at the two ends of the width direction of the bottom support seat 1. The top ends of the two extend outward from the bottom support seat 1 respectively. The X-direction side hanging assembly 6 and the Y-direction side hanging assembly 7 can not only help the main hanging assembly 5 to disperse the gravity load of the pipeline it bears, but also the two groups of X-direction side hanging assemblies 6 and the two groups of Y-direction side hanging assemblies 7 are distributed in four directions outside the main hanging assembly 5, which can antagonize the vibration loads in four horizontal directions brought to the bottom support seat 1 when the soil vibrates, thereby improving the stability of the seismic node bracket and the pipeline.

[0043] Reference Figure 1The X-direction side hanging assembly 6 comprises a first connection seat 61 and an X-direction oblique hanging rod 62. Both ends of the X-direction oblique hanging rod 62 are rotatably connected to the first connection seat 61. The first connection seat 61 at the bottom end of the X-direction oblique hanging rod 62 is connected to the bottom support seat 1 through a second connection bolt 63. The first connection seat 61 at the top end of the X-direction oblique hanging rod 62 is provided with a second anchor bolt 64. The second anchor bolt 64 is used to connect the main body of the building to anchor the anti-seismic node bracket. The first connection seat 61 and the X-direction oblique hanging rod 62 can be connected by bolts, which can facilitate the angle between the first connection seat 61 and the X-direction oblique hanging rod 62 and stably fix the first connection seat 61 and the X-direction oblique hanging rod 62. By rotating the first connection seat 61 and the X-direction oblique hanging rod 62, the X-direction side hanging assembly 6 can be fixed to any part of the main body of the building, which can be a flat surface or an uneven surface at the top of the anti-seismic node bracket. It is only necessary to adjust the angle between the first connection seat 61 and the X-direction oblique hanging rod 62 to make the bottom support seat 1 horizontal.

[0044] Reference Figure 4 The Y-direction side hanging assembly 7 comprises a second connection seat 71 and a Y-direction oblique hanging rod 72. Both ends of the Y-direction oblique hanging rod 72 are rotatably connected to the second connection seat 71. The second connection seat 71 at the bottom end of the Y-direction oblique hanging rod 72 is connected to the bottom support seat 1 through a connection bolt 3 73. An anchor bolt 3 74 is arranged on the second connection seat 71 at the top end of the Y-direction oblique hanging rod 72. The anchor bolt 3 74 is used to connect the main body of the building to anchor the anti-seismic node bracket. The second connection seat 71 and the Y-direction oblique hanging rod 72 can be connected by bolts, which can not only facilitate the angle between the second connection seat 71 and the Y-direction oblique hanging rod 72, but also stably fix the second connection seat 71 and the Y-direction oblique hanging rod 72. By rotating the connected second connection seat 71 and the Y-direction oblique hanging rod 72, the Y-direction side hanging assembly 7 can be fixed to any part of the main body of the building, which can be a flat surface or an uneven surface at the top of the anti-seismic node bracket. It is only necessary to adjust the angle between the second connection seat 71 and the Y-direction oblique hanging rod 72 to make the bottom support seat 1 horizontal.

[0045] When using this bracket: adjust the radial size of the adjustable pipe clamp 4 and its position on the bottom support seat 1 according to the diameter and layout requirements of the pipeline; firmly connect the top of the main hanging component 5 to the main building; adjust the angle of the side hanging component according to the shape of the main building, and firmly connect the top of the side hanging component to the main building.

[0046] Compared with the prior art, the beneficial effects of the present invention are as follows: through the adjustable pipe clamp 4 whose position on the bottom support seat 1 and its own radial size are adjustable, it is possible to adapt to different construction needs, fix pipes of different diameters, and improve the universality of the seismic node bracket. After being manufactured in a template, it can be adjusted by the construction personnel themselves, and the adjustment method is simple, efficient and low-cost; through the main hanging assembly 5 and the side hanging assemblies located around it, the bottom support seat 1 and the adjustable pipe clamp 4 are synergistically suspended, so that the seismic performance of the seismic node bracket can be adjusted to improve the stability of the pipe supported by it.

[0047] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
