Problems solved by technology

[0003] The wall panels of the traditional prefabricated concrete structure are generally reinforced concrete wall panels, which are heavy, and the production, transportation and construction costs are high; the wall panel technology of the traditional prefabricated steel structure is not perfect, and there are still thermal bridges, roof panel leakage, and floor panel sound insulation and the poor heat insulation effect of the wall; the level of industrialization and standardization of building components is low, and it does not match the main body of the steel structure building, which no longer meets the requirements of the modern development of my country's construction industry

Embodiment 1

[0030] Such as figure 1 A light prefabricated exterior wall panel is shown, including a light steel keel frame 3, a rectangular frame surrounded by C-shaped steel, and diagonal ribs 8 arranged at the corners of the rectangular frame. Reinforcing ribs are also provided in the rectangular frame. Diagonal ribs can not only improve the strength of the skeleton, but also serve as the passing point of the connecting piece, so as to avoid the damage of the outer panel or the inner base plate caused by the connecting piece being too close to the edge.

[0031] The inner surface of the light steel keel frame 3 is fixedly connected with the inner base plate 1, and the outer surface of the light steel keel frame 3 is fixedly connected with the outer base plate 7, and a number of through holes are opened on the outer base plate 7, and the outer surface of the outer base plate 7 is fixed. An outer panel 5 is provided, and the outer surface of the outer panel 5 is provided with a plasterin...

Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 is that the profile of the light-duty keel frame is a thin-walled rectangular tube, and the threaded connection is a tension bolt 10 passing through the outer plate, the outer base plate, the light-duty steel keel frame and the inner base plate. On the light steel keel frame, there are reserved holes for the passage of the pull bolts, such as image 3 shown. The various parts are connected by the tension bolts, the reliability is higher, and the structural strength of the wallboard is further improved, and the hard foam polyurethane also plays the role of anti-loosening and rust prevention for the tension bolts.

[0037] The preparation method of above-mentioned two embodiment exterior wall boards, comprises the steps:

[0038] (1) Make the outer board, the outer base board and the inner base board, and open a number of through holes on the outer base board, wherein the outer board and the inner base board are aut...

Abstract

The invention relates to a light prefabricated outer wall plate comprising a light steel keel skeleton, inner base layer plates fixedly connected to the inner side face of the light steel keel skeleton, and outer base layer plates fixedly connected to the outer side face of the light steel keel skeleton and provided with a plurality of through holes. Outer side plates are fixedly arranged on the outer side faces of the outer base layer plates, and cavities defined by the outer base layer plates, the inner base layer plates and the light steel keel skeleton are filled with pouring-type heat-insulating materials; and pouring holes are formed in the side wall of the light steel keel skeleton. According to the light prefabricated outer wall plate, the light steel keel skeleton serves as a bearing body for mounting of all the layer plates, the poured heat-insulating materials are utilized to play a role in thermal insulating and bonding all the layer plates into a hole, and thus a wall plate structure is firm and reliable; meanwhile, the heat-insulating materials achieves looseness preventing and rustproof effects on threaded connecting pieces, and thus the service life of the wall plate is further ensured; and the wall plate can be manufactured in a factory, the construction efficiency is improved substantially, and meanwhile, the industrialization and standardization level is alsoincreased advantageously.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a light-weight prefabricated exterior wall panel and a preparation method thereof. Background technique [0002] Vigorously develop prefabricated buildings, realize industrialization of building parts production, integration of technology applications, standardization of engineering design, assembly of on-site construction, integration of civil engineering and decoration, and informatization of life cycle management. This is a profound change in the industrial transformation and upgrading of the construction field. Major innovations in construction technology and engineering construction methods are an inevitable trend in the development of green buildings and building energy conservation. They are conducive to reducing resource and energy consumption, reducing construction waste and dust pollution, improving construction efficiency and building quality, and contributing to build...
