Description

Embedded steel structure assembly of residential exterior wall panels

technical field

The utility model relates to a building technology, in particular to a prefabricated building component that can be produced in a factory and assembled on site, in particular an embedded steel structure assembled housing exterior wall panel.

Background technique

At present, there are mainly three types of steel structure residential technologies on the market: one is low-rise light steel keel residential technology; the second is medium and high-rise steel structure support system + block wall; the third is medium and high-rise steel structure support system + Lightweight wall panel technology; the first technology is relatively mature, but because the main structure adopts cold-formed thin-walled steel with limited bearing capacity, it is not suitable for multi-storey and high-rise buildings, and it is difficult to promote on a large scale. The second type is far from the concept of building industrialization due to the large amount of on-site masonry work and does not conform to the future development direction. The third technology is still in development and is far from mature, and there are still some technical problems. The biggest problem is that both the inner and outer walls are made of grouted lightweight wall panels, which is easy to cause structural displacement at the connection of the main structure. This phenomenon is particularly prone to occur in some high-rise residential buildings, and this problem is more prominent in some pilot communities that have been built. In addition to the three structures mentioned above, there is also an embedded steel structure assembly building system, which is a green new type of assembly steel structure building system, which is based on the modular "double module" coordination and "module combination" Technology is the main feature of the building and an industrialized building technology system characterized by embedded steel structures and PC panels. This technology runs through the entire process of building (residential) design, processing, installation, equipment installation, decoration, and smart home. , Realize the industrialization, intensification and socialization of the whole process of housing construction, thereby improving the quality and efficiency of construction projects, and realizing energy saving, emission reduction and resource conservation.

The main features of this embedded assembly house are: the building system adopts a dual-modulus coordination mechanism to form modules, which can combine the building planes and building facades of various houses from 80㎡ to 160㎡. As long as the standard board formed by the basic module and some special-shaped boards are added, the plane and elevation dimensions of various living requirements can be met, thereby forming a standardized design and laying the foundation for factory production. The building adopts a steel structure load-bearing system and PC large slab series, laminated floor (roof) panels, EC wall panels, and ALC wall panels to form a complete main structure, which improves the service life and seismic performance of the building. The PC slab adopts an internal insulation structure with concrete on both sides and an insulation layer in the middle, which meets the thermal insulation function and improves the energy-saving effect. At the same time, it meets the requirements of fire prevention and sound insulation. Scaffolding, formwork, plastering and other projects have been basically canceled, beams, columns cast-in-place and steel bar binding and other processes have been cancelled, wet operations on site have been reduced, and the integrated decoration has a flat and smooth surface of the model, eliminating the need for traditional mortar to find Equal process, can directly carry out puttying, whitening and other processes, saving materials. Therefore, the construction period of this prefabricated industrial building is shortened by 2/3 compared with the conventional one, and the labor cost is reduced by 2/3, which ensures safe production and engineering quality. At the same time, the usable area of steel structure residences can be increased by 3% to 5%, and the advantages of energy saving and environmental protection are prominent. After comparative analysis of the cost of the main structure, the cost of the steel structure prefabricated house is basically the same as that of the traditional concrete structure, but its construction period is 1/3 of the traditional one, shortening the investment recovery period, and judging from the current steel market price trend, Traditional labor costs continue to increase, steel prices are falling, and the cost of steel structure housing is expected to further decrease. As one of the key technologies of the embedded steel structure assembly building system, it is necessary to design an embedded exterior wall panel that is light in weight and easy to install.

Utility model content

The purpose of this utility model is to design an embedded steel structure assembly house exterior wall panel according to the needs of the embedded steel structure assembled building system, to replace the traditional hanging or cast-in-place concrete wall, to improve the assembly efficiency and improve the exterior wall panel. aesthetics.

The technical scheme of the utility model is:

An embedded steel structure assembled residential exterior wall panel, which includes a panel body 1, characterized in that the upper side of the panel body 1 is provided with a step body 2 attached to the outer surface of the upper steel beam, and its lower side is provided with an insertion The groove 3 in the lower steel beam is provided with a fixing hole 4 on the step body 2 for fixing the plate body and the upper beam.

The width of the board body 1 is set with a modulus of 3.

The panel body 1 is a sandwich structure, wherein the middle layer is an EPS insulation material layer, and both sides of the EPS insulation material layer are prefabricated concrete panels.

The thickness of the EPS insulation material layer is not less than 150 mm.

The beneficial effects of the utility model:

The utility model can be installed in the steel square column, has beautiful appearance, light weight, fast and convenient installation, and reliable fixing.

Description of drawings

Fig. 1 is the structural representation of the utility model.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1.

An embedded steel structure assembled residential exterior wall panel, which includes a panel body 1 composed of three layers, the middle of the panel body 1 is an EPS insulation material layer 4 with a thickness of about 150 mm, and the outer two layers are reinforced prefabricated concrete panels. The overall composition is a sandwich structure. In order to achieve embedded installation and convenient positioning, the upper side of the board body 1 is provided with a step body 2 attached to the outer surface of the upper steel beam. The thickness of the step body 3 is exactly the difference between the width of the column and the beam. The lower side of 1 is provided with a groove 3 inserted into the steel beam of the lower layer, and a fixing hole 4 for fixing the plate body and the upper beam is provided on the step body 2 . As shown in Figure 1, in order to realize factory production and reduce the number of spare parts, the width of the board body 1 is set at a modulus of 3 during specific design, that is, the width of the board body is a multiple of 3. In addition, on the wall with windows, corresponding window holes are also opened on the board body 1 .

The parts not involved in the utility model are all the same as the prior art or can be realized by adopting the prior art.
