Embodiment 1

[0012] Embodiment 1, a kind of method of making square box of glass fiber reinforced plastics, each panel of square box is prefabricated earlier, carries out square box splicing again, splicing method is: the side panel of square box is hoisted on the bottom panel, bottom panel and side panel and side panel The seams between the panels are reinforced by hand lay-up,

[0013] The steps to make the panel are:

[0014] (1) Making the inner layer of FRP with a thickness of 5-10mm; the gel time is 30-60 minutes;

[0015] (2) Make the interlayer of fine stone mortar for the panel: first, mix fine stone with a certain grade and resin to prepare fine stone mortar, and the weight ratio is: large stones with a particle size of 8-15mm: medium stones with a particle size of 4-6mm: Small stones with a particle size of 0.5-2mm: resin = 15-20%: 25-30%: 45-50%: 8-15%, and the prepared fine stone mortar is laid on the inner layer of the above-mentioned flat glass fiber reinforced plastic, wit...

Embodiment 2

[0017] Embodiment 2, the optimum weight proportion of fine stone mortar is: the large stone of particle diameter 8-15mm: the medium stone of particle diameter 4-6mm: the small stone of particle diameter 0.5-2mm: resin=16-18%: 26 -28%: 46-48%: 10-12%.

Abstract

The invention relates to a method for fabricating a glass fiber reinforced plastic square box. Panels of the square box are prefabricated first and then are spliced into the square box. The splicing method is that the side panels of the square box are hoisted to a bottom panel, and splicing joints between the bottom panel and the side panels and between the side panels are manually pasted for reinforcement. The fabrication steps of the panels are that: (1) the fabricating glass fiber reinforced plastic inner layer with thickness of 5-10mm is fabricated; (2) the fine aggregate mortar interlayer of the panel is fabricated; and (3) the surface of the fine aggregate mortar is ground, the surface is leveled by using resin putty and finally the glass fiber reinforced plastic outer layer of the panel is fabricated. The invention has the advantages that the production preparation tasks are simplified, the overall rigidity is enhanced, the assembling is rapid and simple because the panels are fixed into a whole body in a splicing way, the large square box can be spliced in the field and the transportation difficulty is reduced. Moreover, the invention solves the defects that the fabrication of the glass fiber reinforced plastic square box is very difficult and the square box is apt to be deformed, the cost is reduced because low-cost fine aggregate mortar is used for substituting for the glass fiber reinforced plastic layer, the overall rigidity of the square box is improved and the safety in use is improved.

Description

technical field [0001] The invention relates to a technology for manufacturing FRP products, in particular to a method for manufacturing FRP square boxes. Background technique [0002] Due to the poor rigidity of the flat plate, the FRP square box is prone to deformation. Therefore, it is necessary to fully consider improving the rigidity of the plane during production. The methods are: 1. Increase the thickness of the plate; 2. Design mesh ribs. However, the first method greatly increases the production cost, and the second method makes the production more difficult and affects the appearance. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a method for making a glass fiber reinforced plastic square box that greatly increases the thickness of the flat plate and thereby improves the rigidity of the plane. [0004] The technical problem to be solved in the present invention is achieved through the following tech...
