What are the types of deformation joints, what are the deformation joints, what are the types, and w

In order to prevent the use and safety impact of the building caused by factors such as temperature change, uneven settlement and **, the building is disconnected in the deformation sensitive part in advance during the design, and is divided into a number of relatively independent units, and the reserved gap can ensure that the building has enough deformation space, and the structural joint that is set up is called the deformation joint.

Deformation joints can be divided into three types: expansion joints, settlement joints, and shockproof joints.

1) Expansion joints: Deformation joints are not protected, and building components will be expanded and contracted due to changes in temperature and humidity and other factors. For this reason, vertical joints are usually set up at the appropriate part of the building, and the walls, floor layers, roofs and other components of the house are disconnected from above the foundation, and the building is separated into several independent parts.

2) Settlement joint: between the various parts of the superstructure, due to the large difference in the number of layers, or the difference in the use load; Or due to the large difference in the compressibility of the foundation, in a word, when the uneven settlement of the foundation may occur, it is necessary to set up a joint to divide the structure into several parts, so that the settlement of each part is relatively uniform, so as to avoid additional stress in the structure, and the joint is called "settlement joint".

3) Shockproof joint: Its purpose is to divide large buildings into smaller parts to form a relatively independent earthquake-proof unit to avoid damage caused by uncoordinated overall vibration of the building.

Expansion joints, settlement joints, shockproof joints.

Changshu Guli Town Baimao Linkage Building Deformation Joint Device Factory is an enterprise specializing in the manufacture of building deformation joint devices.

Expansion joints, settlement joints, shockproof joints Now there are 3 seams in one.

Deformation joints are a general term for expansion joints, settlement joints, and shockproof joints. Buildings are often deformed under the action of external factors, leading to cracking and even destruction. A deformation joint is a construction joint that is reserved for this situation.

1. Expansion joint.

Building components will expand and contract due to changes in temperature and humidity and other factors. For this reason, vertical gaps are usually set up in the appropriate parts of the building, and the walls, floor layers, roofs and other components of the house are disconnected from above the foundation, and the building is separated into several independent parts. Joints set up to overcome excessive temperature differences, the foundation can be disconnected from the top surface of the foundation to the roof along the structure.

2. Earthquake-proof joints: In order to make the building more regular and conducive to the seismic resistance of the structure, the foundation can be opened. The purpose of its setting is to divide large buildings into smaller parts to form a relatively independent earthquake-proof unit to avoid damage caused by the overall vibration of the building.

In order to make the building more regular, and the joints that are conducive to the earthquake resistance of the structure, the foundation can be opened. The purpose of its setting is to divide large buildings into smaller parts to form a relatively independent earthquake-proof unit to avoid damage caused by the overall vibration of the building.

In the seismic fortification area, the settlement joints and expansion joints must meet the requirements of seismic joints.

3. Settlement joint.

It refers to the building structure joints set up when the height of the same building is very different, the upper load is unevenly distributed, or when it is built on different foundation soils, in order to avoid uneven settlement and cracking of walls or other structural parts. Settlement joints divide the building into several sections, which are self-contained, from the foundation, walls, floor slabs to the roof.

The seam width is generally 70-100 mm. A vertical joint that completely separates a building or structure from the foundation to the top. In order to avoid the uneven subsidence of each section and the formation of cracks.

It is usually set between parts of the building that vary greatly in height, load or foundation capacity, as well as at the junction of the old and new buildings.

There are several reasons for failure of a failed expansion joint, but experience has shown that failure can be divided into several different categories. This list includes, but is not limited to: damage to transportation and handling, improper installation of inadequate protection, during and after installation, improper anchoring, guidance and support of the system, anchor failure in use, corrosion, system overpressure, excessive bellows deflection, torsion, bellows erosion, and particulate matter in bellows gyration that restricts normal movement.

There are a number of measures that can be taken to prevent and minimize expansion joint failures. During installation, carefully follow the instructions provided by the manufacturer to prevent any damage to the bellows. After installation, carefully inspect the entire piping system to see if there is any damage during installation, whether the expansion joint is in the correct position, and whether the expansion joint flow direction and positioning are correct.

In addition, expand joints are inspected regularly throughout the operating life of the system to check for external corrosion, loosening of threaded fasteners, and damage to anchors, rails, and other hardware.

Deformation joints are a general term for expansion joints, settlement joints, and shockproof joints. Deformation joints can be divided into three types: expansion joints, settlement joints, and shockproof joints.

1. Expansion joint.

The expansion joint requires that the walls, floor layers, roofs and other parts above the ground of the building are all disconnected, and the foundation part does not need to be disconnected because it is less affected by temperature changes.

2. Settlement joint.

Settlement joints are deformation joints set up for the damage caused by uneven settlement of various parts of the building.

3. Shockproof joints.

For building earthquake protection, generally only the influence of horizontal ** waves is considered.

When building a house in the ** area, it should strive to be simple in shape, symmetrical and evenly distributed in weight and stiffness, and the center of gravity and center of gravity of the building should be as close as possible to avoid sudden changes in the plane and façade.

"1) According to the parts used in the building, it is divided into: floor deformation joints, exterior wall deformation joints, interior wall deformation joints, roof deformation joints, and roof deformation joints.

2) According to the characteristics of the deformation joint, it can be divided into: plane type and corner type.

3) According to the structural characteristics of the deformation joint device, it can be divided into: metal cover plate type, metal lock type, single-row embedded flat type, double-row embedded flat type, and rubber embedded flat type.

4) According to the special requirements of the use function, it is divided into: load-bearing and seismic type. "

Deformation seams. What are the three types? Deformation joint device is a kind of device used in the construction industry, due to the temperature difference between day and night, uneven settlement and the sensitive parts or other necessary parts that may cause structural damage, resulting in some wall cracking and pure, or distortion and other phenomena, in the long run, not only unsightly, but also sometimes affect safety.

Therefore, it is necessary to cut the building (pre-pure code first to leave the seam) after the disconnection of each part of the building into an independent unit, or divide it into simple, regular, uniform sections, and make the joints between the sections reach a certain width to be able to adapt to the needs of deformation. Our deformation seam products are mainly used in such situations, put it on to avoid this phenomenon of twisting and cracking.

What are the types of deformation seams?

There are three types of deformation seams! What are the three types of deformation joints? Let me go through them one by one:

Deformation joints have expansion joints.

There are three types of settlement joints and shockproof joints.

The thermal expansion and contraction of the building due to the influence of external temperature changes.

In order to prevent the occurrence of irregular damage to the building, a gap is often reserved at certain distances or at a large structural change along the length of the building, and this gap is called an expansion joint.

Reserve a vertical gap in the appropriate part of the building, divide the building into a number of independent structural units, so that each unit can settle freely, this joint is called a settlement joint.

In order to prevent the damage to the house, a vertical gap must be set to divide the house into a number of independent units with simple shape, stiffness and uniform quality, which is called a seismic joint.

The summary is as follows: 1. Expansion joints (temperature joints.

Corresponding to the deformation caused by the temperature difference between day and night;

2. Settlement joints - corresponding to the deformation caused by uneven settlement;

3. Shockproof seam - corresponding to the deformation that may be caused by **.

<> building deformation joint device is used to cover and decorate the building deformation joint of the building accessories, it is composed of aluminum alloy profile, aluminum alloy plate (or stainless steel plate, brass plate), stainless steel slide bar and rubber insert and other industrial products that integrate practicality and decoration.

Classification of deformation joint building structures and devices.

It is divided into four categories according to the use of the deformation joint device of the building.

Deformation joints on the floor.

Deformation joints of interior walls and ceilings.

Deformation joints of exterior walls.

Roof deformation joints.

According to the structural characteristics of both sides of the deformation joint, it is divided into two types:

Flat type: The installation structure surfaces on both sides of the deformation joint are on the same plane.

Corner type: The installation structure planes on both sides of the deformation joint are perpendicular to each other.

According to the structural characteristics of the deformation joint device, it can be divided into six types:

Metal cover plate type: It is composed of aluminum alloy base, aluminum alloy center cover plate (or stainless steel plate, brass plate) and stainless steel slide rod, and is connected by stainless steel slide rod between the cover plate and the base fixed on both sides of the deformation joint, so as to ensure that when the base is displaced, the metal cover plate is still maintained in the center of the seam when the base is displaced, and has the characteristics of being flat with the decoration layer. Suitable for 50 500mm seam width.

Metal lock type: It is composed of an aluminum alloy base, an aluminum alloy side cover plate and an aluminum alloy sliding plate. The center sliding plate is sandwiched between the side cover plate and the aluminum alloy base, which has a neat appearance and easy installation.

Suitable for 50 200mm seam width, double-row embedded flat type: composed of aluminum alloy base, aluminum alloy center plate, stainless steel slide bar and rubber strip, aluminum alloy center plate is grooved, can be embedded in stone, floor tiles, carpets and other decorative materials, suitable for high cleanliness requirements of the floor. Suitable for 100 300 seam widths.

Single-row embedded flat type: composed of aluminum alloy base and rubber strips, after installation, it is combined with the decoration layer smoothly and tightly, and is suitable for 50mm seam width.

Seismic type: composed of aluminum alloy base, center cover, rubber strip, slide bar and seismic spring, when the first occurs, the slide rod with seismic spring is deformed after being stressed, which can make the center cover rise along the base frame to protect the building structure on both sides of the deformation joint from damage, and so on After the force is eliminated, the center cover will automatically return to its original state It can withstand multi-directional displacement, with the characteristics of smooth seams and good decorative effects. Suitable for 75 500mm seam width, load-bearing:

Increase the thickness of the cover plate and improve the bearing capacity, which can generally meet the passage of 3t vehicles, and can also be customized by the manufacturer according to the design load.
