Two caps for being used to connect the scalable column of advance timbering are symmetrically arranged with, the cap includes top and fixes company with top plate
The contiguous block connect, two through holes set along top plate width, the connection between two through holes are provided with contiguous block
Block block bottom is to top plate direction indent and forms groove, the connecting rod in inverted " u " font is provided with below the groove, and connect
It is embedded at the top of bar in groove, the cap is provided with reinforcement supporting plate close to the side of the second side plate, and opposite side, which is provided with, to be added
Strong support member, wherein, the top for strengthening supporting plate is fixedly connected with contiguous block, and bottom is fixedly connected with the second side plate, described to add
Strong support member include being arranged on vertical gripper shoe below contiguous block and with vertical gripper shoe is set in parallel first is connected
Plate, the top of vertical gripper shoe are fixedly connected with contiguous block, and the top of the first connecting plate is fixedly connected with top plate, vertical gripper shoe
Bottom be fixedly connected with the bottom of the first connecting plate by the second connecting plate.
Described two reinforcement supporting members are connected by two the 3rd connecting plates be arrangeding in parallel, the both ends of the 3rd connecting plate
It is vertical with the first connecting plate of two reinforcement supporting members respectively to be fixedly connected.
Rings seat is provided with second side plate, suspension ring are provided with rings seat.
Plate body bottom of first side plate between two reinforcement supporting members is provided with the breach in isosceles trapezoid.
Compared with prior art, the utility model has the advantages that：
First, a kind of advance timbering beam structure described in the utility model, back timber is in use by cap with that can stretch
Contracting column connects, and cap is more stable under carrying of the reinforcement supporting member with strengthening supporting plate so that back timber with it is scalable
Column connection is more stable, greatly reduces advance timbering and situation about toppling over occurs, and improves the service life of advance timbering；
2nd, beam structure described in the utility model is reasonable in design, can be moved freely between the anchor shaft anchor cable in tunnel, from
And make it that anchor shaft anchor cable need not be removed when using advance timbering, the time is saved, substantially increases production efficiency.
