Detailed Description

In order to make the technical problem, technical solution and beneficial effects to be solved by the present invention more clearly understood, the following description is made in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present invention will be further explained with reference to the accompanying drawings and specific embodiments:

concrete embodiment is shown in fig. 1 to 4, the utility model provides a prefabricated composite wall of single chamber assembled steel mould rack, including wearing to be equipped with diagonal reinforcement unit's heat preservation 1, the first net 2 and the second of welding that is fixed in diagonal reinforcement unit both ends welds net 4, locates the muscle expansion net 3 that has in the first net 2 outside of welding, has the muscle expansion net 3 and forms the concrete placement chamber that is not less than 50mm between 1 with the heat preservation, and the second welds the distance between net 4 and the heat preservation 1 and is not more than 30mm.

Compared with the prior art, the single-cavity assembled steel mould net rack prefabricated composite wall body provided by the utility model comprises a heat preservation layer 1, a first welding net 2, a ribbed expansion net 3, a second welding net 4, diagonal reinforcement units and cushion blocks, wherein the first welding net 2 is arranged on one side of the heat preservation layer 1 at intervals, a pouring cavity for pouring is formed by a gap between the first welding net 2 and the heat preservation layer 1, and the pouring cavity is a concrete pouring cavity with the width not less than 50 mm; the second welding net 4 is arranged on the other side of the heat insulation layer 1, and the distance between the second welding net 4 and the heat insulation layer 1 is not more than 30mm, and the arrangement distance can ensure that a part of the second welding net 4 is embedded into the heat insulation layer 1 after the concrete is poured into the pouring cavity; the reinforcing bar expansion net 3 is arranged outside the first welding net 2, cement mortar is conveniently smeared on the surface of concrete, and in addition, the reinforcing bar expansion net 3 can also improve the strength of the cement mortar on the surface of the concrete.
