Abstract

The utility model discloses a glass fiber reinforced plastic interlayer pipe, particularly a clamping block pipe of glass fiber reinforced plastic wound by fibers, which is composed of a structure layer and a leakage resisting layer. The utility model is characterized in that the outer part and the inner part of the pipe is orderly provided with the structure layer and the leakage resisting layer. A clamping block layer is arranged on the middle part of the structure layer and the leakage resisting layer is the inner wall of the pipe. Thus the clamping block pipe effectively increases the strength and the rigidity of the structure layer. The performance is increased, the uneven thickness of the pipe wall is corrected, the raw material is saved and the raw material cost is reduced.

Description

Fiber fw frp fixture block pipe

The utility model relates to a kind of fiberglass interlayer pipe, specifically is fiber fw frp fixture block shape conduit.

The domestic and international at present various glass fiber reinforced plastic sand-inclusion pipelines of producing, great majority are made up of structure sheaf and impervious barrier, and its structure sheaf is formed by fiber fw frp layer and resin mortar layer (burning into sand layer).The burning into sand layer structural strength of this structure sheaf is low, wall unevenness even, and the cost height.

The purpose of this utility model is to provide the property management of a kind of fiber fw frp fixture block shape, resin sand (diffusing) slurry layer that need not be traditional in structure sheaf, (it is defined as the arbitrary shape solid but adopt block, there is a major diameter to be all block greater than 2.8mm person, conventional resins screed, sand grains directly are 0.3-1.2mm) the sticking layer that unifies, thus the strength and stiffness of raising interlayer, and correct its tube wall became uneven, thereby reduce cost.

Major technique content of the present utility model is, this fiber fw frp fixture block shape property management is made up of structure sheaf and impervious barrier, to pipe, be followed successively by structure sheaf and impervious barrier by pipe is outer, structure sheaf has removed the burning into sand layer and has been made up of outer wrap, fixture block layer, interior winding layer, impervious barrier is the inside pipe wall layer, is made up of inner liner and time inner liner.

Technique effect of the present utility model is, this fiber fw frp fixture block pipe, and its structure sheaf mainly is a load-carrying construction, and impervious barrier is antiseep and anticorrosion.Owing to removed traditional resin mortar layer in the structure sheaf, increased the fixture block layer, therefore the bulk strength and the rigidity of structure sheaf have been increased effectively, raw-material potentiality have been given full play to, improve performance, correct the tube wall uneven distribution, saved raw material, reduce cost, improved the market competitiveness greatly.

Fig. 1 is a structural representation of the present utility model.

Winding layers in 1 outer wrap, 2 fixture block layers, 3,4 inner liners, 5 inner liners.

Realize embodiment of the present utility model as shown in the figure, this fiber fw frp fixture block pipe, form by structure sheaf and impervious barrier, to pipe, be followed successively by structure sheaf, impervious barrier by pipe is outer, structure sheaf is made up of outer wrap 1, fixture block layer 2, interior winding layer 3, and inner liner is that the inside pipe wall layer is made up of inferior inner liner 4, inner liner 5.

The fixture block layer can be the block that all metals such as stone, cement block (concrete), ceramic block, potter's clay piece, unit of plastic, foam-plastic blocks, wooden unit, bamboo piece, nonmetal, organic and inorganic piece, plate, bar, sheet, shell, rod, pipe etc. comprise hollow, solid, the foam porous shape of garden shape, ellipse garden shape, square, rectangle, flute profile, T type, I-shaped and various geometrical bodies, or with the mixture of resin mortar, the maximum major diameter of block size is greater than the block of 2.8mm.

Claims

1, fiber fw frp fixture block pipe, form by structure sheaf and impervious barrier, it is characterized in that being followed successively by structure sheaf, impervious barrier by pipe is outer to pipe, structure sheaf has removed the burning into sand layer to be made up of outer wrap, fixture block layer, interior winding layer, and impervious barrier is that the inside pipe wall layer is made up of inner liner and time inner liner.

2, according to the described fiber fw frp of claim 1 fixture block pipe, it is characterized in that pressing from both sides the block layer can be stone, cement block, ceramic block, potter's clay piece, unit of plastic, foam block, wooden unit, bamboo piece, metal, nonmetal, organic and inorganic piece, plate, bar, sheet, shell, rod, pipe, the block of hollow, solid, the foam porous shape of garden shape, ellipse garden shape, square, rectangle, flute profile, T type, I-shaped and various geometrical bodies, or with the mixture of resin mortar, the maximum major diameter of block size is greater than the block of 2.8mm.
