Abstract
A new hole pipe. The pipe body includes a screen layer in the middle, an outer layer and an inner layer which are attached to the two sides of the screen layer. The screen layer is formed of plain weave mesh grid. The diagonal of the net hole thereof is the same with the pipe body axis; the outer layer and inner layer are made from elastic materials. The screen can be a metal mesh or a non-metal-mesh. The outer layer is made from polyurethane, and the inner layer is made from synthetic plastic. The utility model has advantages that: the screen in the middle greatly increases the tensile anti-rapture strength of the pipe body, the design that the diagonal of the net hole thereof is the same with the pipe body axis brings a function that the utility model can extend or shrink according to the elastic inner and outer layers at the length direction. When the component hole is pressed or vibrating, the utility model is stable, not flat and no collapse failures, anti-high-temperature, anti-wear, and is reliable product which is convenient to use, simple-structured, small friction, low cost, easy to pull out, and never breaks inside the hole under any situation.
Description
Technical field
The utility model relates to a kind of drilling pipe (rod), belongs to building product, is a kind of casement that cement components with holes uses of building in railway, bridges in highway engineering and other large-scale construction engineerings.
Background technology
The bending that the cement components of above-mentioned engineering generally all slightly arches upward is so that member has prestressing force.In the past when building this class A of geometric unitA, the drilling pipe that uses is to use rubber, perhaps make by rubber and cotton, this drilling pipe heaviness, big, the difficult extraction of friction disconnect when withdrawing sometimes, and the part of breaking in the hole is difficult to take out, even member is scrapped, increased engineering cost, influenced programming, made very big trouble to construction.
Summary of the invention
The purpose of this utility model just provides a kind of novel drilling pipe, to solve big, the difficult extraction out of heaviness, friction that existing drilling pipe exists, sometimes when withdrawing, disconnect, the part of breaking in the hole is difficult to take out, even member is scrapped, increase engineering cost, influenced the problem of programming.
The technical solution of the utility model is: the silk screen layer in the middle of its body comprises and the skin and the internal layer that are compounded in its both sides, and described silk screen layer is made of the plain weave net, and the diagonal of its mesh is axially identical with described body; Described skin and internal layer are made by elastomeric material.
Described silk screen can be a wire gauze, also can be non-wire gauze.
Described skin is made by polyurethane; Described internal layer is made by synthetic plastic.
Described internal layer is full of pore, becomes solid barred body.
The utility model has the advantages that: middle silk screen layer has strengthened the tension breaking strength of body greatly, and the design that its diagonal is axially identical with body has at length direction with the flexible performance of flexible ectonexine it.When pressurized shakes in component hole, have good stability, not flat flat, indeformable, high temperature resistant, extremely wear-resisting, be a kind of use light, simple in structure, friction is minimum, cost is low, easy withdrawing, the Reliable Products in the hole of when also can not breaking.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, silk screen layer 1 in the middle of body of the present utility model comprises and the skin 2 and the internal layer 3 that are compounded in its both sides, described silk screen layer 1 constitutes (single or multiple lift) by the wire gauze or the nonmetal silk screen of plain weave, and the diagonal of its mesh is axially identical with described body; Described outer 2 and internal layer 3 make by elastomeric material (as rubber and polyurethane), preferable material is outer 2 to adopt polyurethane, internal layer 3 adopts synthetic plastics, outer 2 closely are combined with each other with internal layer 3 and silk screen layer 1.Constitute outer 2 polyurethane and have high temperature resistant, anti-pulling force, flexible, extremely wear-resisting characteristic; The silk screen layer 1 of centre not only strengthens tension and anti-disconnected performance, and its diagonal has the performance of stretching with skin 2 and internal layer 3; The synthetic plastic material that internal layer 3 adopts has very approximate elasticity, flexible and resistant to elevated temperatures characteristic with the polyurethane that constitutes outer 2, under the prerequisite that can satisfy elastically-deformable requirement, has reduced material cost.Internal layer 3 also can adopt and outer 2 identical materials.
The organizine of silk screen layer 1 and tram can be burst formula side by side, also and row arrangement.
Internal layer 3 of the present utility model also can be full of pore, becomes solid barred body.
The utility model is when withdrawing, and the silk screen at its axial diagonal angle 1 is out of shape when elongating along with the elongation of elastic tube wall, and the variation in diameter of pipe is convenient to extract out, restores to the original state rapidly again after unclamping.After repeated multiple times was used, the diameter of pipe do not reduce, indeformable, do not rupture, wear-resisting, high temperature resistant.Simple in structure, science, rationally, cost reduces, easy to use.
Claims (5)
