Accessories for anti-seismic supports

Introduction Anti-seismic support accessories 1. C-shaped steel, lead screw, female C-shaped steel lead screw combination and lead screw combination serve as load-bearing rods (columns, diagonals, longitudinal diagonals, transverse arms ), C-shaped steel curling with

Accessories for anti-seismic supports

1. C-shaped steel, screw, female screw joint

The combination of C-shaped steel and screw has the function of rod bearing (column, diagonal spacer , longitudinal diagonal struts, transverse arms), the C-shaped steel curling has serrations and there are band mounting holes on the back. All special accessories for earthquake brackets and hangers can be adjusted and installed with any combination.

2. Recessed Corbels and Slots

Corbels are used for wall support and can be used as cross beams to support air ducts, cables, decks, etc. . The oval hole design makes installation easier and can be adjusted to different lengths to meet actual on-site working conditions.

Recessed grooves are used for medium sized fastening systems such as pipex installation (ventilation ducts, air conditioning ducts, water pipes, etc.).

3. Anti-seismic hinges (type A and type B)

Anti-seismic hinges are used between rods and anti-seismic structures or between gates. brackets and structures.Link, the installation angle can be flexibly adjusted according to on-site working conditions and design requirements.

4. Hose clamp (U-shaped hose clamp, O-shaped hose clamp, ohm hose clamp)

U-shaped hose clamp is used for tube lateral unique The attachment of the seismic support and clamps; O-type clamps are used to fix the single-pipe longitudinal seismic bracket and Ohm clamps are used to fix the door-type seismic bracket and; hanger pipes; U-shaped hose clamps, Type O pipes. Hoses and ohmic hose clamps are used with rubber pads for insulation, shock absorption and noise resistance.

5. Fasteners

Special accessories for earthquake supports and brackets are used in combination to strengthen them.

Building electromechanical engineering:

Building electromechanical engineering is an important part of the construction project, mainly including water supply and drainage systems, drainage systems. power supply, air conditioning and ventilation systems, low currents. systems, fire protection systems, intelligent Six aspects of the system. The quality of mechanical and electrical engineering directly affects the overall quality of the construction project, including operational effects, whether it is energy efficient and whether the building is practical when operated.actually put into service.

Electromechanical seismic resistance of buildings:

Refers to the seismic design of electromechanical installations such as pipelines, air ducts, cable trays, etc. Before the promulgation of the standard, domestic protection of electromechanical installations was still in use. It is a load-bearing support system, which mainly plays a load-bearing role, basically it does not take into account the seismic design, which brings great hidden dangers to the safety of the system. The main objective of its anti-seismic support is safety, that is, to minimize the loss of life and property caused by earthquakes. In simple terms, this type of product is also called earthquake support and support.

Seismic support and suspension design

1. Design scope: water supply ≥DN65, hot water,fire protection, air conditioning water pipes or other equipment whose gravity exceeds 1.8KN, air ducts with a rectangular section greater than or equal to 0.38 m2 and circular ducts with a diameter greater than or equal to 0.7 m must be equipped with anti-seismic supports and suspensions.

2. Electrical piping with an inner diameter of at least 60 mm or cable ladders and cable ducts with a gravity of at least 150 KN/M,All bus conduits shall be designed with anti-seismic supports and brackets.

3. Horizontal pipelines must be equipped with lateral seismic supports and supports within 0.6 m of the turning point. When the diagonal reinforcement acts directly on the pipeline, it can be used as a longitudinal anti-seismic. support and suspension for the pipeline on the other side.

4. Each section of horizontal straight pipe must be equipped with anti-seismic side supports and suspensions on two sections.

5. When the distance between two side seismic supports and supports is greater than or equal to the maximum design spacing, one side seismic support and one support should be added in the middle.

6. Each section of horizontal straight pipe must be equipped with at least one longitudinal anti-seismic support and one support.

Installation principles of seismic supports and brackets

Read the construction drawings carefully before installation, carry out on-site investigation and compare them with the construction drawings. At the same time, it must cooperate with the progress of the installation of other types of works. After studying the site according to the construction plans, it is necessary to carry out cabling and positioning work. At the same time, mark the places where hanging objects such as pipes, bridges and air ducts must climb and turn, leaving athus space for the installation of supports and suspensions. When a variety of pipelines are brought together, the principles of small to large, pressure to non-pressure and normal temperature to heat preservation should be followed.

When installing brackets and brackets, they must be installed in strict accordance with the installation spacing, installation method and installation angle required by the drawings. There are four main forms of earthquake supports: a single water pipe system, a single air pipe system, a single bridge system, and a combined system.

1. Installation steps of seismic bracket and single tube bracket

According to the installation type of single tube, the installation steps of single tube mainly include: measurement, anchor bolt. positioning → material cutting → main crane installation → diagonal reinforcement installation → Ininstallation of the stiffening device.

2. Steps for installing anti-seismic brackets and brackets for air ducts

Take a rectangular air duct as an example. According to the shape of the air duct, select the corresponding anti-seismic. -seismic supports and supports for installation. The steps mainly include: measuring, positioning anchor bolts → cutting material → installing main crane → installing transverse beams → installing diagonal reinforcements → installing stiffening devices

3. Installation steps of bridge anti-seismic brackets and brackets

According to the shape of the bridge, select the corresponding anti-seismic brackets and brackets for installation. The installation steps mainly include: measurement, anchor bolt positioning → material. cutting → main crane installation → installationof horizontal → lateral beam, Installation of longitudinal supports → Installation of stiffening devices

Steps for installing combined anti-seismic supports and hangers

There are many types of combinations, but the installation steps are basically the same. Now water pipes take the suit as an example to install. According to the installation form of the combination, select the corresponding anti-seismic brackets and brackets for installation. The installation steps mainly include: measuring, anchor bolt positioning → material cutting → main crane installation → channel steel crosspiece installation, water pipe fixing → installation of lateral and longitudinal supports → installation of stiffening devices.

Seismic supports and supports are widely used in mechanical engineering installationsanical and electrical such as water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, communications, etc. mechanical and electrical construction. In response to earthquake disasters, they can reduce the damage caused by earthquakes, reduce and prevent the occurrence of secondary disasters as much as possible, and achieve the goal of reducing casualties and property losses.
