Abstract

The invention discloses a molding and manufacturing craft for non-load-bearing inner partition wall lightweight wallboard in buildings; wherein, horizontal type molds are adopted by the invention, which are hierarchically cast by slurry and covered by fiber. After the lower layer is cast by slurry and fibers, a mold core pipe is arranged and died, then the upper layer is cast by slurry and fibers; finally, the upper slurry is manually leveled or by using a temper mill. The craft is suitable for hollow lightweight wall boards, sandwich lightweight wall boards and solid air-ejecting lightweight wall boards of various materials. The lightweight wall board produced by the invention has the advantages of uniform, flat and unexposed fiber protective layer in slurry, high bending and tensile strength, and stable production quality.

Description

Flat die shaping technique of light wall board

One. technical field

The present invention relates to the moulding manufacturing technology of non-bearing internal partition wall Light trabs for building, particularly the moulding process of Light trabs.

Two. technical background

Light trabs is the construction material that is used for the non-bearing internal partition wall on a kind of building, and the interior divider wall of multi-story structure generally all adopts Light trabs.At present the Light trabs former that uses all is to adopt formwork erection open-close type machinery, and its moulding process is that fuse pipe, fortifying fibre are contained in the die cavity, behind the matched moulds by manually slip being poured in the die cavity.Because fiber can't be fixed in die cavity, after slip pours into, position of fibers and flatness irregular, the wallboard fiber after the moulding exposes and out-of-flatness, causes the insufficient strength of wallboard, percent defective and height.

Three. summary of the invention

At the deficiency of existing technology, the invention provides the Light trabs moulding process of a kind of horizontal die layering casting, layering laying fiber.

Technical solution of the present invention is as follows:

After mould enters production line, by feeding machine or manually casting ground floor slip and pressing in mould, the about 5mm of thickness, by the fleece-laying machine or manually lower floor's fiber is tiled in above the slip, again by feeding machine or artificial in mould casting second layer slip and plane on the slip is pressed into the shape that meets core pipe Lower Half substantially.By manipulator or manually the core pipe that combines is packed in the mould, again with concavo-convex mould limit, the termination merges fixing.Then by feeding machine or artificial casting the 3rd layered material slurry and flattening in mould, this layered material about 5mm in plane on the mould is again by the fleece-laying machine or manually top fiber is tiled on the slip.At last by feeding machine or artificial casting the 4th layered material slurry in mould, and by planisher or manually will go up the plane and flatten, the wallboard moulding finishes.Light trabs moulding process provided by the invention both can adopt mechanization to produce continuously, also can be used for making by hand.Also be applicable to manufacturing of filled board.The Light trabs that adopts this technology to make has: characteristics such as fiber is smooth, fibrous protective layer is even, wallboard intensity height, mechanization production efficiency height.

Five. the specific embodiment

Embodiment 1:

Embodiment moulding process such as Fig. 1～shown in Figure 4

Fig. 1～Fig. 4 is a kind of concrete fact Example of the present invention, the specific embodiment of embodiment is when the mould die opening state, casting ground floor slip (3) in mould, lay lower floor's fiber (4), the second layer slip (5) of casting again, and the upper surface of second layer slip (5) is pressed into the shape that meets core pipe Lower Half substantially, then the core pipe (8) that combines is packed in the mould, the mould convex-concave is touched limit (1) and (2) close up inwards, after the merging of core pipe end support is fixing, casting the 3rd layered material slurry (6) and pressing in mould, again top fiber (7) is tiled in the 3rd layered material slurry (6) above, the 4th layered material of casting slurry (9), after planisher or manually the last plane of the 4th layered material slurry (9) is touched flat, Light trabs through curing finished product.

Embodiment 2

Fig. 5 is a kind of specific embodiment of the present invention, accompany the foam Insulating board in the wallboard of this embodiment, its forming process is as follows: when die opening state, casting ground floor slip (3) also flattens, lay lower floor's fiber (4), the second layer slip (5) of casting again, then cystosepiment (6) is packed in the mould, punch-die limit (1) and (2) are closed up, face end support is closed up and casting the 3rd layered material slurry (7) and pressing in mould afterwards admittedly the last plane of the 3rd layered material slurry (7) that again top fiber (8) tiled, the 4th layered material of casting again slurry (9), after planisher or manually the last plane of the 4th layered material slurry (9) is touched flat, Light trabs through curing finished product.
