Self-heat-preservation prefabricated outer wall board with frame net rack

Abstract

The invention discloses a self-heat-preservation prefabricated outer wall board with a frame net rack. The prefabricated outer wall board comprises a heat-preservation sandwich board, steel wire net sheets and inclined inserting bars, wherein a space steel wire net rack is formed by the upper and lower steel wire net sheets and the heat-preservation sandwich board is arranged in the space steel wire net rack; the upper and lower steel wire net sheets are arranged at the peripheral edges along with the heat-preservation sandwich board, are bent inwards by two rows and are additionally provided with tie bars to form a frame steel bar cage; and lightweight concrete wall bodies are arranged on the upper and lower surfaces, and the peripheries of the space steel wire net rack. According to the self-heat-preservation prefabricated outer wall board, industrial prefabrication can be realized and the self weight is light; the periphery can be in flexible connection with a main body so that the anti-seismic effect is better; and meanwhile, the self-heat-preservation prefabricated outer wall board has the characteristics of rapid construction speed, low construction cost, energy conservation and environmental friendliness, safety and reliability and good heat preservation effect.

Problems solved by technology

[0002] Since the comprehensive promotion of the policy of "no concrete and limited sticking" at the beginning of this century, blocks have been used to replace solid clay bricks in the filling walls of traditional concrete frame structures, which has achieved certain resource saving effects and reduced structural weight to a certain extent. , but because the infill wall is still a masonry structural component, its integrity is poor. In previous destructive earthquakes, the seismic damage of the infill wall, such as cross shear cracks, is still one of the typical earthquake damages. Although the ring beam structure is adopted The anti-seismic measures such as pillars, but did not fundamentally solve the occurrence of such earthquake damage

On the other hand, in order to prevent the infill wall from flashing and collapsing during an earthquake, the current codes or regulations stipulate that necessary connection measures must be taken between the masonry infill wall and the frame main structure, such as laying tie bars or paving Reinforcement mesh, etc. In this way, the stiffness contribution of the infill wall to the frame structure must be considered, which increases the seismic action. Some scholars have proposed the method of adding horizontal and vertical flexible separation layers during the construction of the block wall, which effectively reduces the The block wall contributes to the rigidity of the main body of the frame, but at the same time it also increases the construction process, prolongs the construction period, and the traditional masonry construction quality is difficult to effectively guarantee

It can be seen that as long as the traditional on-site masonry construction method is still used, there are two fundamental problems: the construction period is long, and the construction quality cannot be absolutely guaranteed, which leads to the fact that the impact of the filling wall on the seismic performance of the frame body cannot be fundamentally and effectively solved

The good luck is not long, a large number of hand-inserted wire boards flood the market, disrupting the normal order, lowering prices, brutal construction, common cracking of surface plastering, seriously affecting use, and even being restricted in some places
