Abstract
The invention innovatively provides a hollow prestressed steel strand. The hollow prestressed steel strand comprises a central pipe and a plurality of steel wires, the steel wires are spirally and peripherally coiled on the central pipe which is a corrugated pipe, and the steel wires include at least one regularly-deformed steel wire or bright steel wire. The hollow prestressed steel strand has the advantages that by adoption of the technical scheme, directly grouting through the middle corrugated pipe can be realized, and simplicity in operation and effectiveness in anchoring are achieved.
Description
Technical field
The invention belongs to steel strand wires field, especially relates to a kind of hollow prestress wire.
Background technology
In rock, dam and tunnel, in order to prevent avalanche and stone from dropping, generally need to adopt anchor cable to carry out roadway support, but the anchor cable that currently used general steel strand wires are made, grouting inconvenience, anchorage effect is not strong yet, and this just needs a kind of steel strand wires that can provide better anchorage effect.
Summary of the invention
It is the problem that existing steel strand anchor cable grouting inconvenience and anchorage effect are not strong yet that the invention will solve.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of hollow prestress wire, comprises a central tube and some steel wires being spirally coiled in described central tube periphery.
Preferably, described central tube is bellows.
Preferably, the pitch of waves of described bellows is 3-9mm, and wall thickness is 0.6-1.2mm, and internal diameter is 10-15mm, and external diameter is 14-20mm.
Preferably, described steel wire comprises rule deforming steel wire or the bright steel wire of at least one.
Preferably, described steel wire is comprise indented wire or the helix rib steel wire of at least one.
Preferably, described steel wire is 9 indented wires or 9 bright steel wires or 9 helix rib steel wires.
Preferably, the lay pitch of 9 steel wire spiral coilings is 12-18 times of whole steel strand wires diameter.
Preferably, the sth. made by twisting of described bellows is to contrary with the direction of peripheral steel wire coiled coil.
The advantage that the invention has and good effect are:
Owing to adopting technique scheme, directly can be in the milk from the bellows of centre, simple to operate, and anchorage effect is stronger.
Accompanying drawing explanation
In order to be illustrated more clearly in the invention embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only the embodiment of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the invention;
Fig. 2 is the central tube schematic diagram of the invention;
Fig. 3 is the assembling schematic diagram of the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the invention embodiment, be clearly and completely described the technical scheme in the invention embodiment, obviously, described embodiment is only the invention part embodiment, instead of whole embodiments.Based on the embodiment in the invention, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the invention protection.
Set forth a lot of detail in the following description so that fully understand the invention, but the invention can also adopt other to be different from alternate manner described here to implement, those skilled in the art can do similar popularization under the condition without prejudice to the invention intension, and therefore the invention is not by the restriction of following public specific embodiment.
Secondly; the invention is described in detail in conjunction with schematic diagram; when describing the invention embodiment in detail; for ease of explanation; the profile of indication device part structure can be disobeyed general ratio and be made partial enlargement; and described schematic diagram is example, it should not limit the scope of the invention protection at this.In addition, the three-dimensional space of length, width and height should be comprised in actual fabrication.
As shown in Figure 1 to Figure 3, the invention comprises a central tube 1 and some steel wires 2 being spirally coiled in described central tube periphery, and described central tube 1 is bellows, and the pitch of waves of described bellows is 7mm, and wall thickness is 1mm, and internal diameter is 12mm, and external diameter is 16mm.The bellows meeting dimensional requirement not only increases hollow area, when reducing bellows wall thickness, not reducing its bearing capacity, and can stretch bending to a certain extent, using convenient.
Described steel wire 2 is 9 indented wires or the rule deforming steel wire such as 9 bright steel wires or 9 helix rib steel wires.
What does is the definition of rule deforming steel wire?
The lay pitch of 9 steel wire 2 coiled coils is 15 times of whole steel strand wires diameter, can ensure the uniformity of whole steel strand wires and bond ability.
The sth. made by twisting of described bellows, to contrary with the direction of peripheral steel wire 2 coiled coil, has ensured the stability of outside diameter.
During use, the invention directly can be in the milk from the bellows of centre, simple to operate, and anchorage effect is stronger, and mechanical property is also more excellent.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
