Problems solved by technology
At present, the master molds for making FRP molds are mostly made of gypsum, wood, cement, paraffin and other substrates. The master molds made of these materials often have low dimensional accuracy, rough surface quality, complicated processing, and are prone to pores, cracks and flatness. Inferior defects
[0005] It can be seen that it is an urgent problem in this field to provide a FRP laminated template and its manufacturing method that can solve the problems of low dimensional accuracy, poor surface quality, and complicated processing in the past.

[0017] The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", etc., are only appended The directions in the figure are only used to explain and illustrate the present invention, not to limit the protection scope of the present invention.
[0018] see figure 1 The composition structure of the FRP laminated formwork is given, which includes four angular frames, and the composite formwork formed by the four angular frames can be installed on the base to be used for the processing and forming of concrete slabs; each angular frame has several Two equidistant U-shaped grooves. When processing concrete slabs, steel bars are interspersed in the middle of the concrete. The ends of the steel bars are erected in the U-shaped grooves. The lowest point of the U-shaped grooves is located in the middle of the angular frame, passing through the U-shaped grooves. To prevent the steel bars from sinking, the...

Abstract
The invention provides an FRP (Fiber Reinforced Plastics) laminated template. The FRP laminated template comprises four angular frames; multiple equidistant U-shaped grooves are configured on each angular frame; when a concrete slab is processed, reinforcing steel bars are interspersed in the concrete; the ends of the reinforcing steel bars are erected in the U-shaped grooves; the lowest points ofthe U-shaped grooves are located in the middle of the angular frames; and the reinforcing steel bars are prevented from sinking through the U-shaped grooves. A manufacturing method of the FRP laminated template comprises the following steps of creating suitable environmental conditions, selecting raw materials, making a gel coat, configuring a resin glue solution, laying a mold base layer, and demoulding and trimming. According to the FRP laminated template provided by the invention, a mold layup method is used to complete the production of a mold reinforcement layer in one day, and release amold in two days; and due to the use of a zero shrinkage curing system, the molding speed of the base layer can be accelerated, and glass fiber injection can be used to obtain higher efficiency, themold has better dimensional stability, and the mold has a better surface effect.
Description
【Technical field】 [0001] The invention relates to the technical field of composite new material manufacturing, in particular to an FRP laminated formwork and a manufacturing method thereof. 【Background technique】 [0002] FRP (Fiber Reinforced Plastics, Fiber Reinforced Composite Plastics), also known as FRP. FRP composite materials are high-performance materials formed by mixing fiber materials and matrix materials in a certain proportion. Generally, FRP has the characteristics of light and hard, non-conductive, high mechanical strength, less recycling, and corrosion resistance. [0003] FRP laminated formwork is a commonly used equipment in the construction field, mainly used for forming and processing concrete slabs. Because of its light weight, rigidity and high mechanical strength, it is more and more popular in formwork production. [0004] The first thing to make a FRP mold is to make a master mold, that is, a real sample of the product. At present, the master mold...
