Description

A mold for preparing fiber grid cloth reinforced board

technical field

The utility model relates to a mold for preparing a fiber grid cloth reinforced plate, which belongs to the technical field of building materials.

Background technique

At present, the building boards on the market generally have the defect of poor toughness. Fiber mesh cloth is widely used in the field of construction engineering because of its good toughness, high tensile strength, light weight, and corrosion resistance.

The invention patent with the publication number CN 105625639 A discloses a carbon fiber cloth roll-type tensioning and anchoring system. In this patent, the carbon fiber cloth is pasted to the bottom of the concrete beam to realize the reinforcement of the concrete beam; this patent also involves the fiber cloth. Fixing, the fixing method is pasting, the disadvantage of the pasting method is that the interface bonding strength between the fiber cloth and the substrate is not high, and the integrity is not strong.

The utility model relates to embedding a fiber grid cloth into a board substrate in an embedded manner to realize integral molding of the board and the substrate, which can better avoid the above-mentioned situation and solve the problem of poor toughness of building boards.

Utility model content

The purpose of this utility model is to provide a mold for the preparation of fiber mesh reinforced plates, the mold realizes the integral casting of fiber mesh cloth and plate matrix by fixing double or multi-layer fiber mesh cloth, so as to prepare Composite products with significantly improved compressive strength, flexural strength, impact strength and tensile strength.

The purpose of this utility model is achieved through the following technical solutions, which include:

A molding component is composed of a first molding surface (1) and a second molding surface (2).

The supporting member has no less than two sets of U-shaped grooves (3) and (4) of grid cloth, the U-shaped grooves are in the shape of toothed ribs and are connected with the toothed ribs inserts (8 ) match; there are bolt holes (5) at the four corners of the supporting member.

A fixing member having four bolts (6), eight nuts (7) and not less than six toothed rib inserts (8).

The molding member of this mold is provided with first molding surface (1) and second molding surface (2) to mold the appearance surface of the product; the distance between the first molding surface (1) and the second molding surface (2) is equal to The thickness of the molded product. The material of the forming component is preferably a material with light weight, high strength and good transparency, such as an organic acrylic plate, to allow direct observation of the bubble characteristics on the outer surface of the air-entrained insulation board during the molding process, and the pore size and uniformity of the product Wait.

The supporting member of the mold, as shown in Figure 2, is preferably made of steel; it is placed between the first forming surface (1) and the second forming surface (2), and is used to support the forming member to form a cavity. There are at least two groups of grid cloth U-shaped grooves (3) and (4) inside the supporting member, the purpose of which is to embed double-layer fiber grid cloth. The U-shaped groove is in the shape of a tooth-shaped convex rib, which fits with the tooth-shaped convex rib insert (8) in the fixed component; there are bolt holes (5) at the four corners of the supporting component.

The bolt (6) in the mold fixing member connects the molding member with the through hole and the supporting member in series, and cooperates with the nut (7) to securely fix the forming member and the supporting member. The tooth-shaped rib insert (8) in the fixed component is embedded in the fiber mesh cloth close to the U-shaped grooves (3) and (4) of the mesh cloth, so as to complete the fixing of the double-layer fiber mesh cloth.

This mold is mainly used for forming fiber mesh reinforced insulation boards, and can also be used for forming fiber mesh reinforced concrete, fiber mesh reinforced composite functional materials, etc.

The beneficial effects of the utility model:

1. The mold of the utility model has changed the traditional molding methods of fiber mesh cloth reinforced plates—spray molding method and water spray molding method. In these traditional methods, the fiber mesh cloth is not fixed firmly and the mixing of water and cementitious materials is uneven. , unable to prepare air-entraining foam products, limited scope of application and other disadvantages.

2. This mold can effectively fix the fiber mesh cloth. When preparing the board, after mixing the raw materials such as water, cementitious material and admixture evenly, it is integrally formed by pouring.

3. In addition to traditional products, this mold can also prepare air-entraining foam products, which obviously improves the limitations and disadvantages of traditional preparation methods.

4. The one-piece molding method adopted by this mold simplifies the operation steps, optimizes the production process, and can significantly improve production efficiency.

detailed description

In order to better understand the utility model, the utility model will be further described below in conjunction with the accompanying drawings, but the utility model is not limited.

The fiber mesh cloth reinforced plate mold of this embodiment, as shown in FIG. 1 , includes a forming member, a supporting member and a fixing member. In this embodiment, the outer dimension is 330mm-360mm-330mm and the height is 30mm, and the inner dimension is 300mm-300mm-300mm and the height is 30mm. In practical applications, the size of the mold can be flexibly adjusted to meet the actual needs of different projects.

Place the supporting member shown in Figure 2 horizontally, then insert the fiber mesh cloth with a size slightly larger than the mold size into the U-shaped groove (3) of the mesh cloth, and place the three tooth-shaped convex rib inserts (8) respectively Insert the fiber mesh into the U-shaped groove (3) of the mesh close to the fiber mesh; use the same method to embed the fiber mesh into the U-shaped groove (4) of the mesh to complete the double-layer fiber mesh on the support member. on the fixed.

Fix one end of the bolt (6) with a nut (7), and then pass the other end of the bolt (6) through the first forming surface (1), the supporting member on which the grid cloth has been fixed and the second forming surface (2 ), and then fix it with the nut (7). Tighten the eight nuts inward along the ends of the bolts (6) until the supporting member is completely fixed to the two molding surfaces.

Place the mold opening upwards on the level ground, mix the raw materials such as water, cementitious material and admixture evenly, and adopt the pouring method to integrally form; after pouring, the mold is cured in the standard cement curing box for 24 hours, demoulding, and then continue After standard maintenance to the specified age, the required plate products can be obtained.
