Problems solved by technology

[0003] However, there are great defects in the use of this formwork: the surface of the building formwork is not smooth, resulting in uneven surface of the poured concrete, which affects its aesthetics. At the same time, more manpower and steps are required to remove the formwork, which increases the production cost.
Due to the brittleness of the FRP on the surface of the formwork, when a large force acts on the surface of the formwork, the FRP on the surface of the formwork is easily broken and damaged, and then the glass fiber will leak out
Because the glass fiber is a synthetic fiber and has high mechanical strength, it is easy to scratch the hands of the removal workers or cause allergies
At the same time, after pouring concrete, due to the fluidity of the concrete and the action of gravity, the concrete will squeeze the surrounding building formwork, which will lead to changes in the formed concrete structure or damage to the building formwork

no. 1 example

[0032] Such as figure 1 As shown, this embodiment provides a building formwork 100a, which includes a building formwork body 102. The building formwork body 102 includes four wooden strips 101 arranged side by side in a horizontal direction, and a layer of reinforcement is coated on the outer periphery of each wooden strip 101. The cloth layers 103 are glued together.

[0033] Wherein, the material of each wooden strip 101 is plywood, the height of each wooden strip 101 is 20 mm in thickness, and the width is 70 mm. The reinforced cloth layer 103 mainly includes the reinforced cloth layer 103 made by curing the non-woven fabric and the resin composition.

[0034] Non-woven fabric is a kind of fabric formed without spinning and weaving. It is just oriented or random arrangement of short textile fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. Non-woven fabrics have the advantages of easy shaping and good...

Embodiment 2

[0076] Such as Figure 5 As shown, this embodiment provides another building formwork 100b, which roughly matches the structure of the building formwork 100a provided in Embodiment 1. However, the positional relationship between the reinforcing cloth layer 103 and the bonding adjacent wooden strips 101 changes, and the arrangement of the composite layer and the protective layer is also different.

[0077] Such as Figure 6 As shown, the reinforcing cloth layer 103 between two adjacent wood strips 101 is formed by curing three cloth pieces 113 and a resin composition. Cloth 113 is polyester. The three cloth pieces 113 are respectively distributed at the two ends and the middle of the wooden strip 101, and the uniform distribution can make the bonding more stable.

[0078] It should be noted that the number of cloth pieces 113 is not limited to 3, but may be 1 or 2 or 5 or even more, and the positions of the cloth pieces 113 are not necessarily uniform. At the same time, the...

Embodiment 3

[0083] The building formwork provided in this embodiment is substantially the same in structure as the building formwork 100a provided in Example 1, the difference lies in the structure of the reinforcing cloth layer 103 between two adjacent wooden strips 101, and the first surface 108 covered on the first surface. The structures of the composite layer 104 and the first protective layer 106 are different from the structures of the second composite layer 105 and the second protective layer 107 covering the second surface 109 .

[0084] Two layers of reinforced cloth layers 103 are arranged between two adjacent wooden strips 101, and the first reinforced cloth layer 103 is formed by curing the cloth strips 110 and the resin composition. Cloth strip 110 is polypropylene fiber. The width of the cloth strip 110 is smaller than that of the wooden strip 101 . The use of cloth strips 110 saves the use of raw materials, thereby saving costs. At this time, the bonding degree and mecha...

Abstract

The invention relates to the building field, in particular to a building template, a manufacturing method of the building template and a building laminated timber. The building template comprises a building template body comprising a plurality of battens. The battens are transversely arranged side by side, and every two adjacent battens are spliced through strengthened cloth layers. The building template body comprises a first surface and a second surface opposite to the first surface. The first surface is sequentially provided with a first composite layer and a first protective layer, and the second surface is sequentially provided with a second composite layer and a second protective layer. The protective layers of the building template can cover glass fibers exposed when glass steel is damaged and can prevent the double hands of a worker conducting separation from being scratched. Meanwhile, the protective layers greatly improve the degree of finish of the surfaces of the building template.

Description

technical field [0001] The invention relates to the field of construction, in particular, to a building formwork, a manufacturing method thereof, and a building wooden square. Background technique [0002] The preparation process of the existing building formwork is mainly to wrap a layer of glass fiber cloth on the outer surface of each wooden strip and pour the resin composition between the wooden strips, so that multiple wooden strips coated with glass fiber cloth are glued in turn. Glued together, as a wooden strip body. Then, a layer of glass fiber cloth is covered on the upper and lower surfaces of the wooden strip, and at the same time, the resin composition is poured, and the resin composition is soaked in the glass fiber cloth, and then the wooden strip body is transported into the shaping furnace, and the liquid resin composition React with glass fiber cloth to solidify. Finally, the surface of the wooden bar body is covered with high-hardness, high-waterproof gl...
