Technical field
The utility model belongs to the glass fiber reinforced plastic pipeline production technical field, relates to a kind of tube wall hollow and strengthens structural glass fiber reinforced plastic pipeline and moulding process thereof.
Background technique
Glass fiber reinforced plastic pipeline (hereinafter to be referred as fiber reinforced plastic pipe) has fabulous anticorrosive property, on intensity, can compare favourably with stainless steel pipeline again, and construction is fast, cost performance is high, has been widely applied to the every field of municipal unit, hydraulic engineering construction.Yet in heavy caliber glass reinforced plastic sand pipe production technical field, because the restriction of technology, appointed condition, the weight of heavy caliber glass reinforced plastic sand pipe can form progression form along with the increasing of caliber to be increased, and causes accumulating, and the difficulty of aspect is safeguarded in construction and installation.
The model utility content
The purpose of this utility model is to overcome the heavy caliber fiber reinforced plastic pipe because of a series of problems that weight produces, and a kind of simple in structure, excellent performance is provided, and strengthens the structural glass steel pipeline from heavy and light, the low tube wall hollow of transportation installation cost.
For achieving the above object, the technical solution of the utility model is: a kind of tube wall hollow strengthens the structural glass steel pipeline, comprise external structure layer and inner structure layer, it is characterized in that: fix by the hollow enhancing construction layer support and connection of built-in spatial structure between described external structure layer and the inner structure layer.
Described spatial structure can be arbitrary shape.The spatial structure axial section is circular pipe as described, or axial section is the Hexagon hollow elongated tubular, is intertwined and connected fixing with described inner structure layer outer side surface.
Described spatial structure and the supporting surface that places described spatial structure both sides are and the perpendicular circle structure of fiber reinforced plastic pipe axis, and thick, the intermediate thin in interior outer periphery of described supporting surface annulus is the I-shape beam shape structure.
Described spatial structure also can be honey comb structure, and the axis of described honeycomb and fiber reinforced plastic pipe axis are perpendicular.
Good effect of the present utility model is: compare with the heavy caliber glass reinforced plastic sand pipe, tube wall hollow strengthens the structural glass steel pipeline, can be on the basis of the mechanical properties such as intensity that guarantee fiber reinforced plastic pipe, decay resistance, owing to there is hollow to strengthen construction layer between external structure layer and the inner structure layer, can reduce or give up original fiber reinforced plastic pipe burning into sand layer fully, thereby alleviate the weight of pipeline self; Reduce operating costs such as construction, transportation, installation.

Embodiment
Structure of the present utility model such as Fig. 1～shown in Figure 5, a kind of tube wall hollow strengthens the structural glass steel pipeline, comprise external structure layer 3 and inner structure layer 1, it is characterized in that: fix by the hollow enhancing construction layer support and connection of built-in spatial structure 4 between described external structure layer 3 and the inner structure layer 1.
Described spatial structure 4 can be arbitrary shape: as axial section is the pipe shape, or is the Hexagon hollow elongated tubular, is intertwined and connected fixing with described inner structure layer 1 outer side surface.
Described spatial structure 4 and the supporting surface 2 that places described spatial structure 4 both sides are and the perpendicular circle structure of fiber reinforced plastic pipe axis, and thick, the intermediate thin in interior outer periphery of described supporting surface 2 annulus is the I-shape beam shape structure.Prefabricated hollow shown in Figure 2 strengthens construction layer likeness in form I-steel and is curled into annulus, arrange linking one by one, this construction layer all adopts " the beam type structure " of humidification at the inside and outside wall jointing, thereby makes that the glutinous company between the outer wall of inwall, inner structure layer 1 of it and external structure layer 3 is tightr.Use this structure on its mechanical property of assurance basis up to standard fully, to save production cost by regulating the size of hollow space voluntarily.
Described spatial structure 4 also can be honey comb structure, as shown in Figure 4 and Figure 5, the axis of described honeycomb and fiber reinforced plastic pipe axis are perpendicular, tube wall C-C shown in Figure 1 position is cut open, section is honey comb like structure, the benefit of this structure is that the structure of each honeycomb all is spaces independently, is arranged in a time-out one by one and does not produce the gap, helps the enhancing of construction layer.
Tube wall hollow strengthens the making moulding process of structural glass sodium channel: in the present embodiment, adopt commercial polyethylene resin, 196 adjacent benzene type unsaturated polyester resins, 9503 terephthalic unsaturated polyester resins, or 9406 metaphenylene unsaturated polyester resin, with the methyl-ethyl ketone peroxide of providing together as curing agent, the weight ratio of resin and curing agent is 100: 1.5, do matrix with the Zhejiang megalith Tex4800 of group alkali-free glass fibre, conventional method makes inside and outside construction layer and hollow strengthens construction layer:
(1) twisting surface felt on mould, use resin impregnated, twine needled mat, again with conventional methods such as resin impregnated, the non-twist glass fibre of alkali-free (meeting the GB/T18369 regulation) is horizontal behind unsaturated resin (meeting the GB/T8237 regulation) dipping, vertically intersection is wrapped in the surface of mould, makes inner structure layer 1;
(2) with making glass fibre reinforced plastic material, the prefabricated hollow of molded method of vacuum bag or pultrusion method strengthens the hollow ring member of construction layer, is wrapped in and can forms hollow enhancing construction layer on the mould.
(3) strengthen the construction layer external chiasma in hollow and twine the glass fibre that is soaked into by unsaturated resin, form external structure layer 3.
Making resin solidification, solidifying temperature by the infrared rays heating after described production process is finished is 50 ℃～60 ℃, and be 10～20 minutes curing time.
The product pipe walls hollow that makes strengthens the structural glass steel pipeline through Mechanics Performance Testing, test result shows: tube wall hollow strengthens the structural glass steel pipeline, in all cases, comprise stiffness coefficient, all shown good performance, reach the technical order of original glass reinforced plastic sand pipe fully, and weight light 60%.Can satisfy the needs of pipe-line construction engineering.
