Embodiment 1

[0029] Such as Figure 1 to Figure 7 As shown, each FRP plate in this embodiment is 206*103*3 channel type FRP plate A, 100*3 flat FRP plate B, 300*3 flat FRP plate C, 400*3 flat FRP plate D , 600*3 flat FRP plate E, 100*100*3-angle FRP plate F, 103*103*3-angle FRP plate G, (units are mm).

[0030] in, figure 1 Shown is a channel-type FRP plate A, which is used to support the formwork of the entire wall thickness. The outside of any end of the notch is connected by pressing or thermosetting epoxy structural adhesive or hot-melt adhesive or mechanical connection. Any one or a combination of several fixes a 40×25×1.8 galvanized flat steel pipe 1. The 40×25×1.8 galvanized flat steel pipe is placed flat and stretched out halfway for connecting adjacent FRP flat plates. In this embodiment, the groove Profile type FRP flat plate A all fixes described galvanized flat steel pipe 1 at both ends.

[0031] Figure 2 to Figure 5 The flat FRP plates B, C, D, and E of different lengths ...

Embodiment 2

[0036] refer to Figure 9 , this embodiment illustrates a kind of FRP formwork for construction, wherein the FRP slabs are made of the same material as the FRP slabs used in Embodiment 1, but the formwork and specification selection are changed according to the construction needs.

[0037] It consists of 2 pieces of 206*103*3 channel type FRP panels A, 4 pieces of 100*3 flat FRP panels B, 2 pieces of 400*3 flat FRP panels D, 4 pieces of 600*3 flat FRP panels E, 2 A 100*100*3-angle FRP flat panel F, two 103*103*3-corner FRP flat panels G, are made by splicing support molds such as Figure 9 FRP formwork (for walls) for construction shown.

Abstract

The invention belongs to the technical field of buildings, and particularly relates to an RRP template for a building and a manufacturing method thereof. The FRP template for the building is formed bysplicing a plurality of FRP flat plates or splicing FRP flat plates and part of auxiliary materials; each FRP flat plate is formed by taking 4800TEX twistless roving with mass content being 35-45% and an alkali-free glass fiber felt with specification being 300-900g / m<2> as reinforcing materials and taking unsaturated polyester resin with viscosity being 350-750 mPa.s as a base body through a pultrusion process, wherein a forming process is mainly a pultrusion forming process and also can be other FRP forming processes such as mould-pressing forming, vacuum guide forming, hand lay-up formingand the like; and any end of each FRP flat plate is fixedly equipped with a connecting tube for connecting the adjacent FRP flat plate. The FRP template has comprehensive advantages of light mass, high strength, convenient splicing, convenient mould removal, high use and transfer time number and low cost.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an FRP formwork for construction and a preparation method thereof. Background technique [0002] The building formwork is a temporary support structure. It is manufactured according to the design requirements so that the concrete structure and components are formed according to the specified position and geometric size to maintain their correct positions and bear the self-weight of the building formwork and the external load acting on it. The purpose of formwork engineering is to ensure the quality of concrete engineering and construction safety, speed up the construction progress and reduce engineering costs. [0003] Formwork commonly used in construction projects includes aluminum alloy formwork, steel formwork, and wood / plywood formwork. The above-mentioned formworks have their own advantages, but also have obvious disadvantages: the one-time use of steel fo...
