Embodiment 1

[0026] Example 1: An open-type profiled FRP board and recycled concrete sandwich insulation composite wall.

[0027] 1. See figure 1 Known, it includes recycled concrete outer wall panels (1), recycled concrete inner wall panels (2), open-type FRP panels (3), FRP wall male connectors (4), FRP wall female connectors (5), where the FRP board is placed in the middle of the wall, and the flange (11) of the FRP board is poured in the inner and outer slabs of recycled concrete, in the space separated by the web (12) of the FRP board and the wall board Filled with thermal insulation expanded polystyrene EPS material (6). At the same time, the FRP wall connecting concave and convex parts (4), (5) are placed at both ends of the wall.

[0028] 2. According to the design requirements, determine the pouring thickness of the inner and outer wall panels, the open profile FRP panel (3), the thickness and position of the FRP wall connecting concave and convex parts (4), (5), support the template,...

Embodiment 2

[0032] Example 2: A necking-type pressed FRP board and recycled concrete sandwich insulation composite wall.

[0033] The construction steps of the composite wall are the same as those in Example 1, and it only needs to replace the open-type profiling FRP sheet (3) with a necking-type profiling FRP sheet (9). See figure 2 .

Embodiment 3

[0034] Example 3: A U-shaped FRP board and recycled concrete sandwich insulation composite wall.

[0035] The construction steps of the composite wall are the same as those in the first embodiment, and only the open-type pressed FRP sheet (3) is replaced with a U-shaped FRP sheet (10). See image 3 .

[0036] FRP materials can also be replaced by organic composite materials such as carbon fiber reinforced composite materials (CFRP), glass fiber reinforced composite materials (GFRP), and aramid fiber reinforced composite materials (AFRP).

Abstract

The invention discloses a heat-preservation combined wall of a FRP plate and a recycled concrete sandwich. The heat-preservation combined wall comprises a recycled concrete outer layer wall plate, a recycled concrete inner layer wall plate, the FRP plate and FRP wall connecting concave and convex pieces. The FRP plate is placed in the middle of the wall, and the wing edges of the FRP plate are poured into the recycled concrete outer layer wall plate and the recycled concrete inner layer wall plate. Separated spaces of webs of the FRP plate and the wall plates are filled with heat-preservation expanded polystyrence (EPS) materials. Meanwhile the FRP wall connecting concave and convex pieces are placed at the two ends of the wall. According to the heat-preservation combined wall of the FRP plate and the recycled concrete sandwich, discarded building waste concrete is recycled to be manufactured into recycled concrete, the resources are saved; through combination of the FRP plate and the recycled concrete sandwich, the defects that a traditional wall is troublesome in construction, high in construction cost, inconvenient to construct, poor in ductility and the like are overcome; on the other hand, the self-weight of the wall is relieved, construction cost is reduced, and the wall simultaneously has a good heat-preservation effect; and the heat-preservation combined wall of the FRP plate and the recycled concrete sandwich can be used for house buildings and industrial plants provided with heat-preservation non-bearing infilled walls and bearing and anti-seismic shear walls.

Description

Technical field [0001] The invention belongs to the field of civil engineering, and particularly relates to an FRP board and recycled concrete sandwich insulation composite wall. Background technique [0002] At present, the amount of waste concrete in the construction waste caused by the demolition of old buildings every year in our country is huge, and it is increasing day by day. The huge processing cost and the environmental problems caused by it are also very prominent. In order to minimize the exploitation of natural resources, the recycling of construction waste must be maximized. It is imperative to effectively process and utilize waste concrete to make it a recyclable renewable resource, and to increase the development and research of its application technology. However, due to the inherent damage of recycled aggregate and its surface covered with a layer of old mortar, the water absorption rate of recycled concrete is large, resulting in the strength and durability of ...
