Embodiment 1

[0024] Example 1, such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 as shown in:

[0025] Taking the strip-shaped refractory and heat-insulating concrete sandwich wallboard as an example, the present invention includes a concrete inner panel 5 and a concrete outer panel 8, and the two sides in the width direction of the concrete inner panel 5 and the concrete outer panel 8 are provided with concrete The anchor 1 of the inner panel 5 and the concrete outer panel 8, the base material of the anchor in this embodiment is a plywood strip. An epoxy resin adhesive coating is provided on the surface of the plywood slats, and evenly distributed sand grains are arranged on the edges of the long sides of the plywood slats. The epoxy resin adhesive coating is carbon fiber impregnated adhesive. A thermal insulation core material 61 is arranged between the concrete inner panel 5 and the concrete outer panel 8, and the thermal insulation core material 61 is selected to...

Embodiment 2

[0033] Example 2, such as Image 6 as shown in:

[0034] In this embodiment, a reinforcing anchor 7 for strengthening the tension between the inner concrete panel 5 and the outer concrete panel 8 is provided between the inner concrete panel 5 and the outer concrete panel 8 . In addition, a fire-proof and heat-insulating layer 62 is provided between the heat-insulating core material 61 and the concrete inner panel. The thickness of the heat insulating core material 61 is 30mm. Suitable for use in southern regions. The insulating core material 61 is foamed plastics, such as EPS, XPS, PU and other foamed plastics.

[0035] When making the fire-resistant and heat-insulating concrete sandwich wallboard of the present invention, the inner panel 5 of fine stone concrete is poured on the mold bottom plate, and after being flattened and compacted, the reinforced anchor 7 is placed, and the reinforced anchor 7 and the The material of the anchor 1 is the same, but the embedded part 2...

Abstract

A fire-proof adiabatic concrete sandwich wallboard and mounting method thereof, belonging to the building technical field, especially the technical field of building outer wall, comprises a concrete inner panel and a concrete outer panel. A binding component for connecting inner panel and the outer panel of the concrete is mounted at two sides of the width direction of the inner panel and the outer panel of the concrete. A metal embedded part is mounted on the inner panel of the concrete. The metal embedded part is fixed to the binding component. An adiabatic core material is mounted between the inner panel and the outer panel of the concrete. A fire-proof groove is mounted at two sides of the length direction of the inner panel of the concrete. This invention has the following advantage:improving the fire-proof performance because this invention comprises a fire-proof groove structure which can effectively prevent the flame directly burning the wallboard core material. And this invention can completely remove the thermal bridge in the wallboard and the whole building.

Description

【Technical field】 [0001] The invention relates to a fire-resistant and heat-insulating concrete sandwich wall panel and an installation method thereof, belonging to the technical field of buildings, in particular to the technical field of building exterior walls. 【Background technique】 [0002] The development of concrete wall panels for building exterior walls is an important part of the industrialization of construction. In addition to the conventional physical and mechanical properties, the ideal concrete wall panels for building exterior walls should also have the following two characteristics: First, the installation method of building exterior wall panels should be in the form of hanging, and the beams, slabs, and columns of the main structure should be It is clad on the inner side of the outer wall to help completely eliminate the cold bridge of the entire building. Secondly, the exterior wall panels should have good thermal insulation properties. [0003] The paten...
