Abstract
The utility model relates to an anchor rod grouting joint. The anchor rod grouting joint comprises a joint mother tube. A movable nut is assembled at one end of the joint mother tube, and threads capable of being matched with a valve are machined through the other end of the joint mother tube. The middle section of the joint mother tube is provided with a groove with a semicircular normal section along the axis of a steel tube, a movable tube piece is movably hinged with the groove, and a locking device is arranged on the outer side of the movable tube piece. The joint mother tube at the lower end of the groove is provided with a lower semicircular groove in a welded mode, an upper semicircular groove is arranged in the movable tube piece in a welded mode, and the lower semicircular groove and the upper semicircular groove are respectively provided with a side semicircular groove. A through hole is formed between the joint mother tube and the movable tube piece. Two side semicircular grooves penetrate through the through hole. After the lower semicircular groove and the upper semicircular groove are folded, the two side semicircular grooves form an inclined hole, an exhaust tube is arranged in the inclined hole, one end of the exhaust tube extends to the external world, and the other end of the exhaust tube extends into the joint mother tube. The anchor rod grouting joint has the advantages of facilitating installation of the exhaust tube needing to penetrate out from the grouting joint and improving construction efficiency.
Description
Technical field
The utility model relates to a kind of bolt grouting joint.
Background technology
According to railroad industry standard " hollow bolt technical condition " (TB/T3209-2008), the medium parcel anchor rod bodies such as combination hollow bolt need injected water cement mortar for underground construction arch supportings such as tunnels make anchor rod body and country rock bonding.Full for guaranteeing slip casting, the combination hollow bolt is furnished with special stack.And the stack that gos deep into bottom the anchor hole adopts plastic pipe usually, is filled in to such an extent that the stop grouting plug of " very tight " flattens for the plastic row tracheae that prevents " softer ", and standard code: the stack therefrom hollow endoporus of the spare anchor body of rod passes.When filling adaptor was installed, stack must be drawn in filling adaptor.Existing filling adaptor is normally: an oblique mouth is set in the side of filling adaptor, and tiltedly mouth has the inclined hole more bigger than stack, and stack is drawn from this inclined hole.Because needing iterative cycles, uses filling adaptor, its inner chamber has been full of mortar and has covered the inclined hole outlet that is positioned at joint inside, in wearing the stack process, not only need to draw the part mortar, even the inclined hole outlet is without mortar, be subjected to the restriction of the on-the-spot lighting condition of underground engineering construction, also be difficult to observe inclined hole outlet position, cause construction to use inconvenience.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of bolt grouting joint, this bolt grouting joint is applicable to the therefrom anchor pole that passes of spare anchor body of rod endoporus of stack, and can conveniently install needs the stack that passes from filling adaptor, improves efficiency of construction.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of bolt grouting joint, this joint comprises the female pipe of joint, the traveling nut that the female Guan Yiduan assembling of joint can match with hollow bolt body of rod external screw thread, the other end processes and can be connected with valve the screw thread that cooperates, it is semicircular groove that the stage casing of the female pipe of described joint is provided with normal section along the steel pipe axis, be movably hinged on the groove and be provided with movable section of jurisdiction, described movable section of jurisdiction and groove are suitable, and be provided with locking device in the outside of movable section of jurisdiction, when closing up and lock, movable section of jurisdiction consists of the cast of the female pipe of described joint, and the seam of sealing activity section of jurisdiction and the female pipe of joint; Welding is provided with second circular groove in the female pipe of the joint of groove lower end, welding is provided with upper half-round slot in the movable section of jurisdiction, upper half-round slot and second circular groove are respectively equipped with the side half slot, be provided with through hole between the female pipe of described joint and the movable section of jurisdiction, two side half slots pass through hole, close up latter two side half slot formation inclined hole at upper half-round slot and second circular groove, and be provided with stack in inclined hole, one end of stack extends to the external world, and the other end extends in the pipe of the female pipe of joint.
As preferably, described junction in the female pipe of groove two side connectors and movable section of jurisdiction arranges respectively hinge, and movable section of jurisdiction is take hinge as the axis folding.
The utility model has been owing to adopted above-mentioned technical scheme, this bolt grouting joint to be applicable to the therefrom anchor pole that passes of spare anchor body of rod endoporus of stack, and can conveniently install needs the stack that passes from filling adaptor, improves efficiency of construction.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after the part of Fig. 1 is analysed and observe.
Wherein, the female pipe of 1-joint, 2-movable section of jurisdiction, 3-upper half-round slot, 4-second circular groove, 5-stack, 6-locking device, 7-hinge, 8-joint connection, 9-hollow bolt body of rod.
The specific embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing to the utility model bolt grouting joint.
A kind of bolt grouting joint as shown in Figure 1 and Figure 2, get 30 millimeters of external diameters, 2 millimeters of wall thickness, length and be 200 millimeters steel pipe, in the steel pipe stage casing, intercept the movable section of jurisdiction 2 of the about 150 millimeters half slot work of a segment length along the steel pipe axis, the remaining main part of steel pipe is made the female pipe 1 of joint.The traveling nut 8 that the assembling of the female pipe of joint 1 one ends can match with the hollow bolt body of rod 9 external screw threads, the other end processes and can be connected with valve the screw thread that cooperates.Second circular groove 4 is welded on the female pipe 1 of joint, upper half-round slot 3 is welded on the movable section of jurisdiction 2, opposite side junction in the female pipe 1 of joint and movable section of jurisdiction 2 arranges hinge 7, movable section of jurisdiction 2 is take hinge 7 as the axis folding, after closing, with the female pipe of joint 1 composite reduction steel pipe shape, and the inclined hole that upper half-round slot 3 and second circular groove 4 lucky compositions can wrapped row tracheaes 5.During use, open movable section of jurisdiction 2, stack 5 inserts the female pipe 1 of joint through nut 8, stack 5 is placed on second unlimited circular groove 4 the activity section of jurisdiction 2 of closing, the seam crossing sealing of movable section of jurisdiction 2 and the female pipe 1 of joint, upper half-round slot 3 and second circular groove 4 just complete wrapped row tracheaes 5, utilize locking device 6 fast fixing movable sections of jurisdiction 2, last, nut 8 is screwed into the hollow bolt body of rod 9 and gets final product.
