What is the definition of a composite wall in construction? What is the definition of a composite wa

Originally, it was actually a laminated wall, not a composite wall.

Simply put, a composite wall consists of multiple layers of walls, and the materials of each layer can be different.

Taking underground engineering as an example, our common terms include "ground connecting wall" and "lining wall", but according to the combination of the two, it should be strictly divided into [composite wall system] and [superimposed wall system].

The composite wall system is a three-layer sandwich structure, and the ground wall is not connected to the lining wall.

The first layer – the ground wall – maintains the structure.

The second layer - waterproof layer - waterproof isolation.

The third layer - lined wall - the main structure.

In addition, the integrity embodied by the composite wall is not in the wall, but the waterproof isolation layer, because the walls on the inner and outer sides are not closely connected, so the waterproof layer can be closely connected to the structural bottom plate, side wall, and roof plate to form a continuous waterproof closure.

On the other hand, a superimposed wall is the opposite.

The two kinds of walls need to be connected by steel bars in a large area, and they are bitten into a tight whole, and when the subway station is constructed, we often say that [two walls in one] actually refers to the superimposed wall system.

Analysis of the structural system of composite walls and laminated walls in metro stations.

It is a wall with a variety of building materials and decorative materials.

The vertical side wall of the underground wall and the main structure is made into a whole, that is, the inner side of the underground wall is chiseled and connected with the main structure with a shear block, which is a structural form that can withstand shear force at the joint part.

The external force acting on the wall during construction, when it is just completed and after a long time is different, and the change of stress or the occurrence of temperature stress, shrinkage deformation stress, etc., due to the different position of the cross brace and the position of the horizontal member.

It is to make the vertical side wall of the underground wall and the main structure into a whole, that is, the inner side of the underground wall is chiseled and connected with the main structure with a shear block, which is a structural form that can withstand shear force at the joint part, and the external force acting on the wall is different during construction, when it has just been completed and after a long time, and the change of stress or the occurrence of temperature stress, shrinkage deformation stress and so on are caused by the different positions of the cross brace and the position of the horizontal member.

Matters added: composite walls are generally composed of thermal insulation materials and surface materials.

1 Thermal insulation materials: There are many types of wall thermal insulation materials. Basically, it can be summarized into two categories: inorganic and organic.

2. Surface materials: Surface materials are divided into two categories: non-metal and metallic.

Load-bearing materials (such as bricks or blocks) are often compounded with high-efficiency insulation materials (such as polystyrene boards, rock wool boards or glass wool boards, etc.) to form composite walls.

It is a benzene board in the middle, and steel wire mesh on both sides is plastered with cement plastered walls.

Walls made of a combination of ordinary bricks and other materials.

It is a wall with a variety of building materials and decorative materials.

In the current building, composite wall, superimposed wall and other building structures are very common, composite wall and superimposed wall are prefabricated buildings, Shi Rangzhi is one of the representative technologies in the field of new construction engineering technology, have good standards, high efficiency, thermal insulation, energy saving, environmental protection and other advantages, although the two similarities are strong, but there are certain differences, so what is the difference between composite walls and superimposed walls? Let's take a look with Qeeka Home experts.

1. What is the difference between composite wall and laminated wall.

The difference between composite wall and superimposed wall lies in the different prefabricated components and application range, the superimposed wall is composed of prefabricated insulation exterior wall panels, thermal insulation material boards, prefabricated outer leaf panels, intermediate cast-in-place layers, prefabricated inner leaf panels and other multi-layer structures, which are generally used in stations, while composite wall panels are made of ordinary Portland cement, sand, pulverized coal, etc., and are widely used in partition walls, steel structures, bathrooms, etc.

2. What are the types of composite walls?

1. Internal insulation composite wall.

The internal insulation composite wall is generally constructed on the inner side of the load-bearing wall, mainly the thermal insulation material can be compounded on the inner side of the load-bearing wall, it is very simple, and the scope of application is wide, the key is to meet the basic load-bearing premise of the building, and can be appropriately thinned, flexible, in the construction is generally required to do the protection of the covering layer, or install the air insulation layer in the insulation layer to keep warm, isolate moisture.

2. External thermal insulation composite wall.

The difference between the external thermal insulation composite wall and the internal thermal insulation composite wall is that it is constructed outside the load-bearing wall, that is, the thermal insulation material is compounded on the outside of the load-bearing wall, and the annihilation achieves the purpose of thermal insulation and heat insulation, in addition to protecting the main structure, prolonging the service life of the building, eliminating the influence of thermal bridges, saving energy, improving the humidity of the wall, etc., it is very powerful to keep the room temperature constant, and it also avoids the damage of the insulation layer by decoration.

Summary: The above is an introduction to the difference between composite walls and superimposed walls, I hope the content shared can give you some reference, if you want to know more about relevant knowledge, you can **** Qeeka Home to consult.

Laminated walls and composite walls are new building products with the advantages of high efficiency, thermal insulation and environmental protection. Therefore, it is widely used in modern building construction. However, many people don't know much about these two walls, so what is the difference between a superimposed wall and a composite wall?

The difference between a laminated wall and a composite wall is that the prefabricated components are different and the range of applications is different. It is composed of multi-layer structures such as superimposed wall exterior wall panels, insulation material boards, outer leaf panels, and intermediate cast-in-place layers, which are often used in stations; The composite wall is composed of a variety of building materials, such as Portland cement, sand, pulverized coal, etc., instead of traditional bricks and tiles, and is widely used in partition walls, bathrooms and other areas.

What are the hidden disturbances of composite wallboard:

1. Moisture-proof and good main structure.

Although the surface of the composite wall panel does not have any waterproof finish, it can still stay dry when exposed to water. And it can be nailed or drilled in any part of the wall without causing damage to the wall.

2. Sound insulation and increase the usable area.

The sound insulation effect of composite wall panels is much higher than that of ordinary walls, and generally 90 mm of lightweight interior walls can block the volume of 43db. Moreover, the thickness of the composite wall panel is half of that of the wall tiles we commonly use, so it can also greatly increase the usable area.

3. Fireproof and environmentally friendly.

The fire performance of the composite wall panel reaches the Class A standard, that is, it can be burned for 4 hours at a high temperature of 1000 degrees, and at the same time will not emit toxic gases.

4. Light weight and good seismic performance.

The density of composite wall panels is 1 3 of ordinary wall tiles, and the weight is only 1 6 of wall tiles. Moreover, it is a prefabricated wall, so the impact and bending resistance are twice as high as that of ordinary masonry walls.

Summary: The above is the difference between the superimposed wall and the composite wall and the advantages of the composite wall panel, I hope to help friends in need, if you need to know more about the relevant knowledge in the later stage, welcome to pay attention to Qeeka Home.

Walls can generally be divided into five categories according to materials, uses, characteristics, location, etc.:

1. Classification according to wall materials 1Brick wall The bricks used for the wall include ordinary cat earth bricks, drilled porous bricks, drilled hollow bricks, lime sand bricks, coke ballast bricks, etc. 2.

Aerated concrete block wall Aerated concrete block is a lightweight material, which is made of cement, sand, finely ground slag, fly ash, etc., with aluminum powder as foaming agent, and made by steaming and curing. It has the characteristics of small apparent density, cut, sound insulation, and good thermal insulation performance, and is mainly used for non-load-bearing partition walls and infill walls of frame structures. 3.

Stone wall Stone wall is made of natural stone, mainly used in mountainous areas and stone-producing areas, and is divided into stone wall, whole stone wall and stone wall. 4.Plate wall The materials of the plate wall are mainly reinforced concrete plates, aerated concrete plates, stone blue plates, etc., and glass curtain walls, metal curtain walls, etc. are also of this type.

5。Load-bearing concrete hollow small block wall This type of wall is made of C20 concrete and is mostly used in residential buildings with 6 floors and below. Second, according to the location of the classification of the wall according to its position in the building is divided into the outer wall and the inner wall, according to the direction and there are longitudinal walls and horizontal walls, the long direction in the rectangular plane of the building is longitudinal, the wide direction is horizontal.

3. Classification according to the load-bearing mode The wall is divided into transverse load-bearing, longitudinal load-bearing, mixed load-bearing, etc. according to the load-bearing mode. When the floor slab is supported on the transverse wall, it is called transverse load-bearing; When the floor slab is supported on the longitudinal wall, it is called longitudinal load-bearing; When the floor slab is partially supported on the transverse wall and part is supported on the longitudinal wall, it is called mixed load-bearing. Fourth, according to the characteristics of the force classification 1

Load-bearing wall The load-bearing wall bears the vertical load transmitted by components such as roofs and floor slabs, as well as horizontal loads such as wind and force. 2.Self-weight walls Self-weight walls only bear the loads of the walls themselves, not the loads transmitted by components such as roofs and floors.

3.Retaining wall The enclosure wall is mainly protected from wind, snow, rain, etc., and has the functions of heat preservation, heat insulation, sound insulation, and waterproofing. 4.

Partition wall The partition wall is mainly to divide the larger building space into several small rooms. The partition wall should meet the requirements of sound insulation and line of sight separation. 5. Classification according to the construction practice According to the construction method of the wall, the wall can be divided into solid wall, clay hollow brick wall, empty bucket wall (including sleepless empty bucket wall, sleeping empty bucket wall, composite wall) and so on.

Composite wall panel is a new generation of industrially produced high-performance building partitions, which are composed of a variety of building materials, replacing the traditional brick front sail tile, which has the obvious advantages of environmental protection, energy saving, pollution-free, lightweight, earthquake-resistant, fireproof, thermal insulation, sound insulation, and fast construction.

The difference between a composite wall and a laminated wall is that the prefabricated components are different and the range of applications is different. The superimposed wall is composed of multi-layer structures such as prefabricated thermal insulation exterior wall panels, thermal insulation material panels, prefabricated outer leaf panels, intermediate cast-in-place layers, and prefabricated inner leaf panels, which are generally used in stations; The composite wallboard is made of ordinary Portland cement, sand, pulverized coal, etc., which is widely used in partition walls, steel structures, bathrooms, etc.

Composite walls are generally composed of thermal insulation materials and surface materials.
