Wallboard for building

Abstract

The invention provides a wallboard for a building, which comprises at least one wallboard, wherein each wallboard is provided with a frame which is formed by upper, lower, left and right four metal section bars; an inner decorative plate is connected with one side of the frame; an outer decorative plate is connected with the other side of the frame; a heat-insulating material is filled between the inner decorative plate and the outer decorative plate; the cross sections of the four metal section bars all have the shape of irregularly shaped bulges or irregularly shaped slots; or one of the four metal section bars has the shape of irregularly shaped bulge while the other has the shape of irregularly shaped slot; when a plurality of wallboards are connected, the irregularly shaped bulges are matched with the irregularly shaped slots; an outwards raised top tray is arranged on the cross section of each of the irregularly shaped bulges, two ends of the top tray are respectively connected with the upper ends of vertical plates and all the plates form a cavity; an inwards raised top panel is arranged on the cross section of each of the irregularly shaped slots, the two ends of the top panel are respectively connected with the upper ends of a panel and all the plates form one cavity; the top panel, a first vertical panel and a second vertical panel form one slot; and the slot is located on the exterior of the cavity. The invention can solve the problem of the prior art.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to a building wall panel. Background technique [0002] With the continuous improvement of the technological level of the construction industry, residential construction needs to develop in the direction of industrialization. The walls, kitchens, toilets, etc. on the building are produced in industrial workshops, and then transported to the construction site for assembly, so as to reduce the workload of on-site construction and the pollution of the site environment, and fundamentally improve the construction progress and efficiency. Urgent requirements for the development of the construction industry. [0003] At present, most of the building exterior wall panels are reinforced concrete prefabricated structures, and the following problems are found in use: 1. The weight of itself is relatively high, and it requires high load-bearing strength for the foundation and ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the building exterior wall panels are reinforced concrete prefabricated structures, and the following problems are found in use: 1. The weight of itself is relatively high, and it requires high load-bearing strength for the foundation and frame of the building, so the building foundation and The design standard of the frame is increased, which leads to an increase in the project cost; second, its own strength is relatively high, and it is easy to cause damage or damage to the frame of the building during hoisting or earthquakes and other accidents; third, the production and installation efficiency is low , it not only has a long production cycle, but also takes time and effort to install on the building; 4. The surroundings of the wall panels are in a plane shape. When multiple wall panels are assembled on the building frame, the exact distance between each wall panel Flat positioning is quite inconvenient, resulting in low installation efficiency, and although the gaps between the wall panels are sealed, they cannot fundamentally prevent the infiltration of rainwater; 5. The periphery of the window is in a flat shape, which cannot effectively prevent rainwater from flowing to the window and the window. Infiltration into the gap of the frame, etc.
