Embodiment 1

[0035] With reference to Fig. 1 and Fig. 3, Fig. 1 represents the production process flow of a kind of lightweight concrete composite wallboard of the present invention, and it carries out following process successively:

[0036] A. Put more than one cement slab into the mold frame. The cement slab used is glass fiber reinforced cement slab. The size of the mold frame depends on the specifications of the wallboard to be made. The cement slab

[0037] 2 It can be replaced by gypsum board, silicon-calcium board or steel mesh board.

[0038] B. Fill the first layer of concrete layer 5 on the cement slab 2. The concrete used in the concrete layer 5 is lightweight high-strength concrete, which is mixed with cement and filler, wherein the cement is Portland cement and sulfoaluminate Cement-like or aluminate-like cement, the filler is a single or a mixture of more than one of the following materials: sand, gravel, ceramsite, expanded perlite, polystyrene foamed particles, expanded ve...

Embodiment 2

[0045] With reference to Fig. 2 and Fig. 4, Fig. 2 represents the production technological process of a kind of lightweight concrete composite wallboard of the present invention, and it carries out following process successively:

[0046] A. Put more than one cement slab 2 into the mold frame. The cement slab used is glass fiber reinforced cement slab. The size of the mold frame depends on the specifications of the wallboard to be made. The cement slab 2 can be gypsum board, calcium silicate board or stencil instead.

[0047] B. Fill the first layer of concrete layer 5 on the cement slab 2. The concrete used in the concrete layer 5 is lightweight high-strength concrete, which is mixed with cement and filler, wherein the cement is Portland cement and sulfoaluminate Cement-like or aluminate-like cement, the filler is a single or a mixture of more than one of the following materials: sand, gravel, ceramsite, expanded perlite, polystyrene foamed particles, expanded vermiculite, ci...

Embodiment 3

[0054] With reference to Fig. 5, the process of the present embodiment is identical with embodiment two (referring to Fig. 2), and material used is also roughly the same with embodiment one, difference is process:

[0055] C. The thermal insulation material 4 pre-clamped in the steel mesh 3 is combined with a fireproof material layer 6, and the fireproof material layer 6 is a refractory material such as mineral wool board, rock wool board, volcanic rock wool board or glass wool board.

[0056] The product structure of this embodiment is shown in Figure 5, and this wallboard is used in occasions with higher fire protection requirements.

Abstract

A construction method for light weight concrete wall, floor plate and sound screen on road follows the steps as: A. put plate into a module frame; B. fill in a premier layer of concrete on the plate; C. on the premier concrete layer put a steel web pre-inserted with heat preservation material and connected to the frame; D. grout a secondary layer of concrete filling into the steel web or put plate on it; E. modeling press. F. standing and harden.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for manufacturing lightweight wall boards, floor boards or expressway sound barrier boards including concrete layers. Background technique [0002] Due to its superior comprehensive performance, lightweight composite wall panels are becoming more and more popular in the field of modern architecture. The company's earlier application for a patent "lightweight composite exterior wall panels and its manufacturing method (patent application number is 200610054638.9)" , can produce composite exterior wall panels with better comprehensive performance. The characteristics of this type of exterior wall panels are: a load-bearing layer of reinforced concrete layer with reinforced mesh, and a lightweight thermal insulation material is placed in the sandwich of the load-bearing layer, which can greatly reduce the weight of the board itself. The weight of the board can gr...
