Where are the three wing rings of the civil air defense casing used

The casing between civil air defense and civil air defense is three wing rings, and the casing between civil air defense and non-civil air defense is two wing rings.

Waterproof casings have flexible waterproof casings.

Structurally speaking, the flexible waterproof casing has three wing rings and a pressure flange, and the rigid waterproof casing has one wing ring. The role of the wing ring:

Judging from the name, it is called waterproof wing ring, and it can be known that the function of the wing ring is waterproof, in addition, because the waterproof casing is an embedded part.

In the installation process, it needs to be fixed in the special position of the steel skeleton of the wall, so the wing ring has a fixed role.

This is one of the practices of the civil air defense engineering ventilation pipe through the airtight wall, and the "air defense basement ventilation equipment installation" 07FK02 atlas is called the type of embedded pipe, and another type of embedded pipe is called type.

The difference between the two is: the former has three airtight ribs (it is not called a wing ring in the civil air defense profession), which are at both ends of the pipe and the pipe **; The latter has only two airtight ribs, which are the pipe end and the pipe **.

There are two functions of pipe port welding sealing ribs, one is that when the ventilation pipe penetrates the closed wall, it is no longer necessary to take the embedded pipe out of the wall, which is convenient for the construction of the formwork and can also ensure the construction quality of the embedded pipe; Second, the ventilation pipe and the airtight rib are welded to ensure the straightness of the pipe outside the wall.

Two types of embedded pipes, respectively suitable for two-end pipe and one-end pipe. If you are worried about the wrong direction when the pipe is embedded in the pipe, you can use all the pipe instead.

For example: the diffusion chamber and the dust chamber through the wall pipe adopt the type, and the diffusion chamber side is connected with an elbow; The wall pipe of the dust chamber and the filter chamber is adopted, and the side of the filter chamber is connected; The wall pipe of the filter room and the fan room is typed, and the two ends are connected.

Hello Chi Zi Kiss I am happy to answer this question for you. Yes. The casing between civil air defense and civil air defense is a three-way wing ring, and the casing between civil air defense and non-civil air defense is the source wing ring of the two families.

The waterproof casing is divided into flexible waterproof casing and rigid waterproof casing, structurally speaking: the flexible waterproof casing has three wing rings and a pressure flange, and the rigid waterproof casing has a wing ring. The role of the wing ring:

Judging from the name, it is called waterproof wing ring, you can know that the function of the wing ring is waterproof, in addition, because the waterproof casing is an embedded part, it needs to be fixed in the special position of the steel skeleton of the wall during the installation process, so the wing ring has a fixed role.

Kiss! Hello, happy to answer your <>

The rigid waterproof wing ring is suitable for structures (buildings) that do not bear the vibration and telescopic deformation of pipelines at the wall of pipelines, and is suitable for the renovation of buildings or pipelines with limited space at the walls of pipelines or where pipelines are installed before structures (buildings) or pipelines. For areas with ** fortification requirements, such as the use of 02S404 rigid waterproof wing ring, the pipe into the pool wall or the outer wall of the building should be set up with a flexible connection nearby. 1.

The thickness of the concrete wall or brick wall at the pipe penetration should not be less than 200, otherwise one or both sides of the wall should be thickened. 2.The dimensional tolerances and geometric tolerances of welded structures are carried out in accordance with JB.

The welding adopts manual arc welding, the electrode model E4303, the grade J422, and the basic form and size of the weld groove are implemented in accordance with GB958-88. 3.When the steel pipe is installed vertically, grout or concrete can be used instead of expanded cement.

Do you have any other questions?

In civil air defense engineering, <> threading is a device used when threading wires or pipes through walls or floor panels. The following are some of the anti-cannula situations in which the use of a thread is usually required for repentance:1

Wire traversal: When installing wires (such as power lines, network cables, etc.) through the walls or floors of civil air defense projects, it is usually necessary to use threads to protect the wires and ensure that they pass through the crossing point safely and smoothly. 2.

Pipeline crossing: If there are water pipes, gas pipes, heating pipes and other pipes that need to pass through the walls or floors of civil air defense projects, it is also necessary to use threads to protect the pipes and reduce the impact on the civil air defense structure. 3.

Fire and smoke prevention requirements: According to the requirements of civil air defense engineering, in order to ensure the effect of fire and smoke prevention, when wires and pipes pass through the civil air defense structure, it is usually necessary to use a thread made of refractory materials to meet the corresponding fire and smoke prevention requirements. It should be noted that the requirements and standards for threading in specific civil air defense projects may be different, and will vary according to the specifications, design requirements and specific engineering requirements of different regions.

Therefore, in the actual construction, the construction unit and the construction unit should carry out specific operations according to the relevant design documents and standards. If you need to use threading in civil air defense projects, it is recommended that you consult and negotiate with relevant professionals, engineers or construction team members to ensure compliance with local codes and safety requirements.

Summary. It is stabilized in the special part of the steel frame of the wall, so the wing ring has the effect of fixing it.

The waterproof casing in the middle of civil air defense and non-civil air defense is two wing rings.

It is stabilized in the special part of the steel skeleton of the wall, so the wing ring has the effect of fixing, and the intermediate waterproof casing of civil air defense and non-civil air defense is two wing rings.

Yes, the casing between civil air defense and civil air defense is three wing rings, and the casing between civil air defense and non-civil air defense is two wing rings.

The waterproof casing is divided into flexible waterproof casing and rigid waterproof casing, structurally speaking: the flexible waterproof casing has three wing rings and a pressure flange, and the rigid waterproof casing has one wing ring. The role of the wing ring:

Judging from the name of the acacia, it is called the waterproof wing ring before the cherry, you can know that the role of the wing ring is waterproof, in addition, because the waterproof casing is an embedded part, it needs to be fixed in the special position of the steel skeleton of the wall during the installation process, so the wing ring has a fixed role.
