Problems solved by technology

However, in the production process, each wooden strip is independently coated, and the large-width glass cloth needs to be cut into relatively narrow cloth strips to wrap each wooden strip. The coating process is relatively complicated. The process is prone to overlap and cause smooth problems

Embodiment 1

[0030] A formwork formed of wooden strips covered with a full width of glass cloth, such as figure 1 As shown, it includes a plurality of wood strips 1 arranged side by side, and the wood strips are wood strips with uniform cross-section processing, or at least make their thickness processing consistent, that is, the thickness and width processing are all consistent, the width may be inconsistent, and the length may be consistent or inconsistent , but the template width after splicing is consistent; the template is provided with an inner layer of glass cloth layer 2 that is bonded together by immersing the wooden strip wrappers arranged side by side and then coated again for increasing strength. The outer layer of glass cloth layer 3 bonded by epoxy resin is then cured to form the final template, wherein the inner layer of glass cloth layer is formed on the wooden bar without breaking between the wooden bars The whole wide glass cloth layer is staggered below; the wooden strip...

Embodiment 2

[0032] A formwork formed of wooden strips covered with a full width of glass cloth, such as figure 1 As shown, the template includes a plurality of wooden strips 1 arranged side by side, and the wooden strips arranged side by side are coated with an inner layer of glass cloth 2 and an outer layer of glass cloth 3 and immersed in epoxy resin for bonding and curing to form the template, wherein , the inner layer of glass cloth is not broken between the wooden strips, forming a whole wide glass cloth that is staggered on the top and bottom of the wooden strips; as figure 2 and image 3 As shown, the cladding process is as follows: first, the multiple wooden strips required to form the formwork are divided into two rows of upper row 4 and lower row 5, such as image 3 As shown, the upper row is the 1st, 3rd, 5th, and 7th wooden strips arranged in sequence in the template wooden strips, and the 2nd, 4th, and 6th wooden strips in the lower row are the sequentially arranged wooden ...

Embodiment 3

[0037] A formwork production line formed by covering wooden strips with a whole width of glass cloth, such as Figure 4 , Figure 5 and Figure 6 As shown, it includes a wood strip primary coating section 9, a buffer dipping section 10, a secondary coating section 11, a forming and curing section 12 and a template puller 13 connected sequentially; Figure 5 As shown, an dripping glue tank 14 is provided above the buffer dipping section to complete the dipping of the wooden strips after the primary coating, and the dripping glue tank is provided with resin dripping holes for the gap between the wooden strips; Pressure rollers 15 are respectively arranged above and below the coating section, and the pressure rollers are used to guide rolling and pressing the secondary coated glass fiber cloth 16 impregnated with resin and pasted on the surface of the wooden strip. Its dripping glue tank is also used to cover the glass fiber cloth dipping tank on the wooden strips arranged side...

Abstract

The invention discloses a formwork formed by wrapping battens with whole wide glass cloth and a production line. The formwork comprises the multiple battens arranged side by side, and is formed by wrapping the battens with the inner glass cloth and the outer glass cloth and infusing epoxy resin for adhesion and solidification. The inner glass cloth layer is a whole piece wrapping the upper and lower faces of the battens in a crossing manner without breaking off between the battens. According to the formwork, the whole piece of wide glass cloth wraps the battens in a crossing manner firstly, so that the connecting structure of the battens arranged side by side is improved, the traditional manner that battens are wrapped independently and adhere to one another with resin is changed to the manner that the battens are connected by the glass cloth and the resin at the same time, so that the connection strength between the battens is improved, and the strength property of the formwork is improved.

Description

technical field [0001] The invention relates to the field of building consumables, in particular to a formwork, a method and a production line formed by covering wooden strips with full-width glass cloth. Background technique [0002] Building formwork is the main tool for concrete structure engineering construction. In the structural engineering of cast-in-place concrete, formwork engineering generally accounts for 20% to 30% of the cost of concrete structure engineering, 30% to 40% of labor costs, and 50% of the construction period. about. Formwork technology directly affects the quality, cost and benefit of engineering construction. Therefore, formwork technology is an important part of promoting the progress of construction technology. [0003] For this reason, the inventor has developed a formwork formed by glass cloth-coated wooden strips bonded and pressed with resin. This formwork has completely changed the use mode of the traditional formwork in the construction i...
