Abstract
The utility model discloses a double-layer anchor tray which comprises two single-layer anchor trays, wherein the peripheries of the two single-layer anchor trays are fixedly connected through a connector and inner holes of the two single-layer anchor trays are fixedly connected through a pipe. According to the double-layer anchor tray provided by the utility model, the two single-layer anchor trays are fixedly connected into a whole body through the connector and the pipe. When the double-layer anchor tray is used with an anchor in a matching form, the exposed length of an anchor screw thread is reduced, the anchor is prevented from being disintegrated by gangues after firing, the double-layer anchor tray is detachable and reusable, the supporting strength and the supporting effect of the anchor are enhanced and the supporting cost of the anchor is saved.
Description
Technical field
The utility model relates to bolt support technology, relates in particular to a kind of double-deck anchor rod pallet board.
Background technology
Anchor rod pallet board cooperates anchor pole to finish supporting to coal mine down-hole rock tunnel usually, existing anchor rod pallet board is single layer structure, as shown in Figure 1, 2, during concrete supporting, anchor pole 2 threaded ends need to pass in the mesopore 11 of anchor rod pallet board 1, tunnel inwall 3 is established in one side 12 holders that make anchor rod pallet board be level, and the not threaded end of anchor pole hangs to be established, as shown in Figure 3; But existing individual layer anchor rod pallet board structure, because the threaded part of anchor pole is exposed at the pallet outside, very easily the crumble screw thread of anchor pole of the rear spoil of blowing out, most anchor poles can not reuse, and have caused great waste.
The utility model content
The double-deck anchor rod pallet board that the utility model provides is used for overcoming defective of the prior art, realizes effectively protection anchor pole, increases the recycling rate of waterused of anchor pole.
The utility model provides a kind of double-deck anchor rod pallet board, and this bilayer anchor rod pallet board comprises two individual layer anchor rod pallet boards, and periphery one circle of two described individual layer anchor rod pallet boards is fixedly connected with by connector, and the endoporus of two described individual layer anchor rod pallet boards is fixedly connected with by a pipe fitting.
Further, described connector is that many steel bar intervals are arranged, the periphery of two described individual layer anchor rod pallet boards is welded respectively at described steel bar two ends.
Wherein, the length of described pipe fitting is 30 millimeters.
The double-deck anchor rod pallet board that the utility model provides is by the integral body that is fixedly connected to form of connector and pipe fitting and two individual layer anchor rod pallet boards; When being used in conjunction with anchor pole, not only reduce anchor pole screw thread protruded length, avoided behind the big gun spoil anchor pole that crumbles, detachably reused, and strengthened supporting intensity and the supporting effect of anchor pole, saved the supporting expense of anchor pole.

The specific embodiment
Such as Fig. 4, shown in Figure 5, the utility model embodiment provides a kind of double-deck anchor rod pallet board, this bilayer anchor rod pallet board comprises the first individual layer anchor rod pallet board 10 and the second individual layer anchor rod pallet board 20, be fixedly connected with by connector 4 between the periphery of the periphery of the first individual layer anchor rod pallet board 10 and the second individual layer anchor rod pallet board 20, the endoporus 11 of the first individual layer anchor rod pallet board 10 is fixedly connected with by a pipe fitting 5 with the endoporus 21 of the second individual layer anchor rod pallet board.The first individual layer anchor rod pallet board 10 and individual layer two anchor rod pallet boards 20 are prior art, can both buy in market.
The double-deck anchor rod pallet board that the utility model provides is fixedly connected to form an integral body by connector 4 and pipe fitting 5 with the first individual layer anchor rod pallet board 10 and individual layer two anchor rod pallet boards 20; When being used in conjunction with anchor pole 2, not only reduce anchor pole screw thread protruded length, avoided behind the big gun spoil anchor pole that crumbles, detachably reused, and strengthened supporting intensity and the supporting effect of anchor pole, saved the supporting expense of anchor pole.
As the specific implementation of above-described embodiment, connector 4 is that many steel bars or spacing of reinforcement are arranged, the periphery of the first individual layer anchor rod pallet board 10 and the second individual layer anchor rod pallet board 20 is welded respectively at steel bar or reinforcing bar two ends.Connector 4 also can be a rectangular steel tube or round steel pipe.Pipe fitting specifically adopts steel pipe, and endoporus 11 peripheries of steel pipe one end and the first anchor rod pallet board weld respectively, and the endoporus 21 periphery welding of the other end and the second anchor rod pallet board guarantee support rigidity, and the length of steel pipe is 30 millimeters, and is suitable with the screw thread length of anchor pole 2.This kind structure fabrication is simple, directly anchor pole is penetrated in the steel pipe during use to get final product, and is very convenient, and its intensity and supporting effect can both satisfy the instructions for use of anchor pole.
It should be noted that at last: above each embodiment is not intended to limit only in order to the technical solution of the utility model to be described; Although with reference to aforementioned each embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
