Abstract
Description
Technical Field
[0001] This utility model relates to the field of seismic bracing and support systems for buildings, specifically a seismic bracing and support system for lateral pipes in concrete structures. Background Technology
[0002] With the continuous development of urban infrastructure construction, the layout of internal pipe systems in buildings is becoming increasingly complex, placing higher demands on the stable installation of various types of pipes such as water supply, air conditioning, fire protection, and drainage. In traditional buildings, pipe supports and hangers typically only bear static loads, and their design is mainly focused on load-bearing, neglecting the ability to respond to lateral dynamic loads such as earthquakes. Especially in earthquake-prone areas or high-rise buildings, the lack of effective seismic connection structures can easily lead to pipe instability, detachment, and even secondary disasters.
[0003] Currently, most seismic bracing systems on the market are arranged longitudinally. For pipe support structures installed laterally on walls, their seismic performance has not been systematically designed. Especially in concrete walls, due to limitations in anchoring methods and pipe location, traditional support structures cannot meet the multiple requirements of "shear resistance, vibration resistance, and shock absorption." Furthermore, some existing products have excessively rigid connection points and poor adjustability, making them unsuitable for multi-angle construction or different pipe diameter conditions, resulting in low installation efficiency and poor stability.
[0004] Furthermore, the lack of lateral support systems with diagonal bracing for energy dissipation is a major shortcoming in current seismic suspension design. During an earthquake, diagonal members without a proper angle will cause the vibration to act directly on the pipe body, easily leading to deformation, damage, or the risk of collapse.
[0005] Therefore, we urgently need to design a seismic-resistant hanger for lateral pipes in concrete structures to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a seismic-resistant hanger for lateral pipes in concrete structures to solve the problems mentioned in the background art.

[0008] A seismic-resistant hanger for lateral pipes in a concrete structure includes: a first connecting seat, one end of which is connected to the concrete structure wall via a self-expanding bottom anchor bolt; the other end of the first connecting seat is movably connected to one end of a second connecting seat via a pivot; the other end of the second connecting seat is connected to the lower side wall of one end of a channel steel via bolts; the front side wall of the other end of the channel steel is connected to one end of a U-shaped connecting seat via bolts; the other end of the U-shaped connecting seat is movably connected to one end of a connecting block via a pivot; and the other end of the connecting block is connected to one end of a pipe clamp via bolts.
[0009] As a preferred technical solution of this utility model, the self-expanding bottom anchor bolt is of M12 specification and has a size of 18×80mm.
[0010] As a preferred technical solution of this utility model, the cross-sectional dimensions of the channel steel are 41mm×41mm and the thickness is 2.5mm.

[0013] As a preferred technical solution of this utility model, the connection position between the U-shaped connecting seat and the channel steel is provided with an angle adjustment mark, specifically an angle scale.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This utility model provides a seismic-resistant hanger for lateral pipelines in concrete structures, which adopts a multi-node rotatable connection structure, including a rotating shaft connection between connecting seat one and connecting seat two, a movable connection between the channel steel brace and the U-shaped connecting seat, and a flexible connection between the connecting block and the pipe clamp. The whole structure forms a spatial mechanical system with energy-dissipating and buffering capabilities, which can effectively disperse stress and absorb energy under earthquake or impact loads, and significantly improve the stability and seismic performance of the pipeline system under lateral disturbances.
[0016] Furthermore, this utility model uses channel steel diagonal bracing set within an angle range of 45° to 59°, combined with a preset angle scale adjustment structure, which not only facilitates quick on-site installation and leveling, but also enhances the system's adaptability to different wall layouts and pipe diameter specifications.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] See Figure 1 and Figure 2 This utility model discloses a lateral pipe seismic hanger for concrete structures, aiming to enhance the stability and safety of pipes under earthquakes or other lateral loads. The seismic hanger embodies its seismic design philosophy in terms of connection layout, structural rigidity, and energy dissipation mechanism. The structure is as follows:
[0023] This device includes core components such as connecting seat 1, self-expanding bottom anchor bolt 2, connecting seat 2 3, channel steel 4, U-shaped connecting seat 5, connecting block 6, and pipe clamp 7.
[0024] The connecting seat 1 is welded from steel plate and anchored to the concrete structure wall by M12 self-expanding anchor bolts 2 with dimensions of 18×80mm, providing high pull-out resistance to ensure that the hanger will not fall off at the root during an earthquake. To enhance the flexible response during vibration, the connecting seat 1 and the connecting seat 2 are connected by a pin shaft, allowing relative rotation within a certain range to absorb some seismic energy and alleviate stress concentration.
[0025] The connecting seat 3 and the channel steel 4 are connected by high-strength bolts. The channel steel 4 is a hot-rolled channel steel with a cross-section of 41mm×41mm and a thickness of 2.5mm, exhibiting high overall rigidity and strong load-bearing capacity. The installation angle of the channel steel is 45°~59°. This angle setting is based on the "diagonal bracing energy dissipation" principle in seismic mechanics, which can effectively decompose lateral seismic forces into axial forces and transfer them to the concrete structure, thereby reducing the direct impact on the pipeline body.
[0026] The front end of the channel steel 4 is fixed to the U-shaped connecting seat 5 by bolts. The U-shaped connecting seat 5 is used to connect the diagonal braces at different angles to the vertical pipe support system. The U-shaped connecting seat 5 and the connecting block 6 are connected by a rotating shaft, which allows for small-angle swinging under vibration, helping to avoid structural damage caused by rigid impact. In addition, the U-shaped connecting seat is equipped with angle scale markings on the outside, which facilitates precise adjustment of the installation angle during construction and improves the consistency of the support system.
[0027] Connecting block 6 serves as a transitional connection component, and it is bolted to pipe clamp 7. Pipe clamp 7 is a double-eared clamp structure, which is fixed around the outer circumference of the pipe and is treated with anti-corrosion paint, providing high strength and rust and corrosion resistance to ensure long-term reliability. The clamping force can be adjusted by bolts to accommodate different pipe diameters, and it is recommended for use with water pipes or air conditioning main pipes with a diameter of 382A.
[0028] Under lateral loads such as earthquakes, the hanger system, through its structural system of "upper flexible connection - middle rigid channel steel diagonal bracing - lower multi-degree-of-freedom connection", effectively absorbs vibration energy, avoids pull-out, twisting and falling off, and effectively improves the seismic toughness and service life of the entire pipeline system.
