Abstract
An anchor-line isolating frame relating to the prestressing force technology field of a rock anchoring provides a handy and lightly weighed anchor-line isolating frame. The anchor-line isolating frame consists of a plank body and a grout hole arranged on the plank body. At the outer flank of the plank body an open bar tendon hole is arranged, the minimum measurement of which is smaller than the inside diameter of the open bar tendon hole. The utility model is applicable to occasions where a plurality of prestressing force tendons are required to be bunched and then penetrated into a pore canal to be grouted, such as a construction of geotechnical engineering, a hydroelectric engineering and a bridge construction. Compared with the prior art, the utility model is lightly weighed, moreover, can load a plurality of prestressing force tendons into the frame swiftly and deftly, and better solves the problems of penetrating a plurality of prestressing force tendons into the pore canal, the inconvenience of penetration in the grouting construction and the asymmetry of the backward grouting. The utility model has the advantages of high construction efficiency and good construction quality.
Description
Technical field
The utility model relates to the prestressing technique field of rock bolting, especially a kind ofly many presstressed reinforcing steels is formed in an orderly manner a branch of, penetrates support used in the duct then.
Background technology
Anchor cable needs one section one section ground of a plurality of anchor cable isolating frames to make each anchor cable isolated when penetrating the duct, makes it to realize orderly arrangement, to strengthen bond stress between anchor cable and the hole wall.At present the anchor cable isolating frame that uses is by being provided with a plurality of muscle hole in the circular plate body and grout hole constitutes.There is following problem in this technical scheme: the muscle hole of (1) anchor cable isolating frame all is arranged in the plate body, for porous anchor cable isolating frame, long presstressed reinforcing steel need be connected by root, and anchor cable is worn time-consuming, the effort of muscle on the anchor cable isolating frame; (2) anchor cable isolating frame outside is a complete circle, and big with the duct contact surface when anchor cable penetrates the duct, the resistance of reeving is big; (3) the anchor cable isolating frame only is provided with grout hole, muscle hole, and during grouting, slurry can only return out from the gap of gap, hole wall and the rope of muscle hole and muscle or from the anchor cable bottom, causes to return slurry and be obstructed, and causes the part to return to starch inhomogeneous in the duct in, can not guarantee construction quality.
Summary of the invention
Subject matter to be solved in the utility model provides a kind of anchor cable isolating frame easy to use, lightweight.
In order to address the above problem, the scheme that the utility model adopts is: it comprises plate body and the grout hole that is located on the plate body, and the described plate body outside is provided with opening muscle hole, and the opening minimum dimension in this opening muscle hole is less than the opening rib-holed inner diameter.So that presstressed reinforcing steel buckles into opening muscle hole from described opening part when using, make it to play effect of contraction.
Above-mentioned opening can open to the plate body outer ledge, so that presstressed reinforcing steel buckles into opening muscle hole from described opening part; The shape of described plate body outer ledge is preferably arcwall face, to reduce the resistance that plate body is reeved in the duct.Also can be provided with on the above-mentioned plate body and return the slurry hole, uneven phenomenon is starched in returning that grouting may occur in the duct when constructing in order to solve.
Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:
1, because the plate body outside is provided with opening muscle hole, the opening minimum dimension in this opening muscle hole is less than the opening rib-holed inner diameter, thereby, presstressed reinforcing steel only needs to buckle into opening muscle hole along opening muscle hole opening part and gets final product, and difficult drop-off, therefore, this anchor cable isolating frame has improved efficiency of construction and quality greatly, has saved labour hour.
2, owing to the arcwall face that is shaped as of plate body outer ledge, therefore in the process of reeving, reduced the friction in anchor cable isolating frame and duct, be convenient to reeve.
3, because anchor cable isolating frame plate body outward flange by the hole disjunction of opening muscle, is the multistage cambered surface, but not only weight reduction and when wearing muscle in the duct, can reduce that therefore uneven rock, helps the anchor cable installation to the obstruction of anchor cable isolating frame in the duct in.
4, because the anchor cable isolating frame is provided with a plurality of slurry holes of returning, slurry is returned out from return the slurry hole, therefore, can guarantee engineering construction quality better.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 be among Fig. 1 A-A to view.
Fig. 3 is the user mode structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples structure of the present utility model is described in further detail:
Fig. 1, Fig. 2 and shown in Figure 3, this anchor cable isolating frame includes plate body 1, is provided with 5, three grout holes 4 in 3 muscle holes and nine in the plate body 1 and returns slurry hole 3, and the outside of plate body 1 is provided with nine opening muscle holes 2.The opening in opening muscle hole 2 opens to the plate body outer ledge, and the minimum dimension d of opening is less than opening rib-holed inner diameter D.Plate body 1 outer ledge be shaped as arcwall face.
This anchor cable isolating frame is when use connects anchor cable, no matter be bifilar, three strands, four strands, five strands and even 37 strands, only need anchor cable 6 is buckled in the opening muscle hole 2 along opening muscle hole opening part, can effectively separate and keep equidistant, thereby make its proper alignment; During grouting, slurry can return out the hole 3 from returning slurry, in the time of can avoiding anchor cable isolating frame part to return slurry being obstructed in the duct part return and starch uneven phenomenon.It is main raw material(s) that this anchor cable isolating frame can be taked the high-quality polyethylene, cooperate enhancing to add material and cast, so this anchor cable isolating frame strength character is good, and existing hardness, flexible is difficult for embrittlement again, and in light weight.Be not only applicable to geotechnical engineering construction, be applicable to hydroelectric project, road and bridge construction etc. yet.
Claims (3)
1, a kind of anchor cable isolating frame comprises plate body and the grout hole that is located on the plate body, it is characterized in that: the described plate body outside is provided with opening muscle hole, and the opening minimum dimension in this opening muscle hole is less than the opening rib-holed inner diameter.
2, anchor cable isolating frame as claimed in claim 1, it is characterized in that: described opening opens to the plate body outer ledge; Described plate body outer ledge be shaped as arcwall face.
