Basic information
It is used to support the structural members of the overhead laying pipeline on the ground, support the pipeline and limit its deformation and displacement, and bear the elastic force of internal pressure, external load and temperature deformation from the pipeline.
Divided into fixed bracket and movable bracket. Movable support is divided into sliding support, guiding support, rolling support and hanging support.
Pipe supports will be used wherever pipes are laid, also known as pipe supports, pipe fittings, etc. As the supporting structure of pipelines, according to the operational performance and layout requirements of pipelines, pipe racks can be divided into fixed and mobile types. The place where the fixed point is set becomes the fixed bracket. This kind of pipe rack cannot move relative to the pipe rack. Moreover, the deformation of the fixed pipe rack after being stressed is smaller than that of the pipeline compensator, because the pipe rack should have sufficient rigidity. Movable pipe supports are used where intermediate supports are arranged. Relative displacement is allowed between pipes and pipe supports, and thermal deformation of pipes is not restricted.
classify
1. According to the load, it is divided into three grades: ultra-light (Q), intermediate and ultra-heavy (Z). In each load level, there are four structural types: axial sliding, bidirectional sliding, guided sliding and double guided sliding.
2. According to the material of the bracket, it can be divided into steel structure, reinforced concrete structure and brick-wood structure.
3. According to the purpose, it can be divided into movable bracket (bracket that allows the pipeline to move on the bracket) and fixed bracket (bracket fixed on the pipeline). The fixed bracket is used where the axial displacement of the pipeline is not allowed, and several commonly used fixed brackets are given in the figure.
Movable support is divided into sliding support, guiding support and rolling support.
method of erection
The installation method of pipe support is as follows:
1. Installation of buried support
2, welding bracket installation
3, expansion bolt method bracket installation
4, hoop method bracket installation
5, nail bracket installation
Construction requirements
The national standard Code for Acceptance of Construction Quality of Building Water Supply, Drainage and Heating Engineering (GB50242-2002) has the following requirements for pipe supports:
Article 3.3.7? The installation of pipe supports, hangers and supports shall meet the following requirements:
1, the position is correct, and the embedding should be smooth and firm;
2, fixed bracket and pipeline contact should be close, fixed shadow is firm;
3. The sliding supports should be flexible, and there should be a gap of 3 to 5 mm between the sliding supports and the chute, and the longitudinal movement should meet the design requirements;
4. Hangers and suspenders of non-thermal extension pipes shall be installed vertically;
5. Hangers and suspenders with thermal extension pipes should be offset in the opposite direction of thermal expansion;
6, fixed on the building structure, hanger shall not affect the safety of the structure.
By introducing the product information of pipeline support, we have a better understanding of what classification is. After knowing what a pipe support is, we can make better use of it. Pipe supports are waterproof and corrosion-resistant, and easy to install. If you need to decorate your home with pipe supports, you can refer to Bian Xiao's introduction, hoping to help you.
