Metal-free prefabricated cement sheet composite wall

Abstract

The invention discloses a metal-free prefabricated cement sheet composite wall which comprises two parallel formworks, the two formworks are made of prefabricated fabric reinforced concrete sheets, a plurality of trapezoidal columns arranged along the wall face are arranged on the opposite faces of the two parallel formworks, and the two parallel formworks are connected through connecting pieces. The prefabricated fabric reinforced concrete thin plates are adopted to form the formworks, the thickness of the plate faces is reduced, so that transportation and building are facilitated, the construction speed is increased, and the anti-bullet and anti-explosion performance of the wall is improved by laying the multiple layers of fiber fabric nets. Through cooperation of the flat plates and the trapezoidal folded plates, the formworks on the two sides have certain bending strength and overall stability, then the connecting pieces are arranged between the formworks on the two sides of the wall for fixing, filled tamped immature soil or cemented soil and the like are restrained transversely, and therefore the vertical bearing capacity of the wall is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a metal-free prefabricated cement sheet composite wall. Background technique [0002] The HESCO explosion-proof wall (HESCO) commonly used in military industry is a simple explosion-proof wall that is easy to make. This kind of wall uses galvanized steel wire mesh and internal polypropylene bags as templates, and is filled with sand and soil. This kind of wall can only be used as a temporary explosion-proof wall, and the wall is usually not load-bearing. Although the explosion-proof wall made of reinforced concrete can be built with floors and roofs, the construction of reinforced concrete requires a lot of scaffolding and formwork. The process is too complicated. [0003] In the prior art, the method of sandwiching rammed earth walls with prefabricated reinforced concrete slabs is simpler than that of cast-in-place reinforced concrete walls. However, the thickness of ...

This kind of wall can only be used as a temporary explosion-proof wall, and the wall is usually not load-bearing. Although the explosion-proof wall made of reinforced concrete can be built with floors and roofs, the construction of reinforced concrete requires a lot of scaffolding and formwork. The process is too complicated

[0003] In the prior art, the method of sandwiching rammed earth walls with prefabricated reinforced concrete slabs is simpler than that of cast-in-place reinforced concrete walls. However, the thickness of reinforced concrete slabs is limited by the requirements of the protective layer of steel bars and cannot be too thin, and its concrete blocks are relatively thin. It is heavy and inconvenient to transport; the rammed earth formwork made of reinforced concrete prefabricated slabs has poor integrity; the existence of steel bars in concrete has an unavoidable influence on electronic signals. The signal transmission is unfavorable; and the speed of laying on site is slow and the construction period is long; the method of laying two walls with masonry and rammed earth is as slow as the method of laying concrete prefabricated panels, and the construction period is long, so there is an urgent need for a metal-free prefabrication Cement thin plate combination wall to solve the above problems
