Abstract
The utility model relates to a kind of evacuation platform for tunnel fixed support, and comprise curved support, cross binding and gripper shoe, it is welded by steel plate combination.Described curved support can be close to the circular surface in tunnel, and curved support is provided with installing hole, and installing hole quantity is no less than two, for the connection of pre-buried channel flow in curved support and tunnel structure matrix.The radian of described curved support and and described cross binding between angle should design according to different tunnel form actual conditions, ensure cross binding in the horizontal direction, described cross binding upper surface is used for placing evacuation platform channel plate, and described fixed support all carries out galvanizing by dipping process.Compared with prior art, the utility model has the advantages that: this fixed support and tunnel structure matrix junction are set to arcuate structure, curved support can be close to the circular surface in tunnel, compared with traditional linear pattern support, space is no longer left in the both sides of support, makes the space availability ratio of circular tunnel reach maximization.
Description
Technical field
The utility model relates to a kind of platform fixed support, particularly relates to a kind of evacuation platform for tunnel fixed support.
Background technology
The fixed installation of the similar tunnel space such as subway inner platform adopts support bracket fastened form more, because of strict to the security requirement of installing, the various unfavorable factors such as vibrations, fatigue and corrosion will be considered simultaneously, the design and devdlop aspect of tunnel frame in the past, many uses crab-bolt carries out anchoring installation, form of structure and selection are all more single, can not adapt to the needs of support installing form.
At present, how in tunnel structure matrix, to bury pre-buried channel flow underground, carry out being connected and fixed of external structure by T-shaped bolt, but in circular tunnel, great majority adopt the form of linear support, waste certain tunnel space.
Utility model content
The purpose of this utility model is exactly to overcome the defect existed in above-mentioned prior art and a kind of sound construction, the joint space-efficient circular tunnel platform fixed support that provide.
To achieve these goals, the technical solution adopted in the utility model is: evacuation platform for tunnel fixed support comprises curved support, cross binding and gripper shoe.It is welded by steel plate combination, it is characterized in that: described curved support can be close to the circular surface in tunnel.
Described curved support is characterized in that: curved support is provided with installing hole, and the quantity of installing hole is no less than two, and concrete quantity designs according to concrete load-bearing conditions.
Described curved support is characterized in that: curved support is connected with T-shaped bolt with conduit pre-buried in tunnel structure matrix.
The radian of described support bracket fastened curved support and and cross binding between angle should design according to different tunnel form actual conditions, ensure cross binding in the horizontal direction.
Described cross binding upper surface is used for placing evacuation platform channel plate.
Described fixed support all carries out galvanizing by dipping process.
Compared with prior art, the utility model has the advantages that: this fixed support and tunnel structure matrix junction are set to arcuate structure, curved support is connected with T-shaped bolt with conduit pre-buried in tunnel structure matrix, curved support can be close to the circular surface in tunnel, compared with traditional linear pattern support, space is no longer left in the both sides of support, makes the space availability ratio of circular tunnel reach maximization.
Accompanying drawing explanation
Fig. 1 is the structural representation of support bracket fastened a kind of embodiment of evacuation platform for tunnel of the present utility model.
In figure, sequence number illustrates: 1-curved support, 2-cross binding, 3-gripper shoe, 4-baffle plate, 5-channel plate, 6-pre-buried channel flow, 7-T type bolt.
Detailed description of the invention
Below in conjunction with Fig. 1, the technical solution of the utility model is described in detail, but content of the present utility model is not limited thereto.
As shown in Figure 1, evacuation platform for tunnel fixed support comprises curved support, cross binding and gripper shoe.It is welded by steel plate combination, and curved support is provided with multiple installing hole, for the connection of conduit pre-buried in curved support and tunnel structure matrix.The radian of support bracket fastened curved support and and cross binding between angle should design according to different tunnel form actual conditions, ensure cross binding in the horizontal direction.Cross binding upper surface is used for placing evacuation platform channel plate.
The foregoing is only embodiment of the present utility model citing, and be not used to limit scope of authority of the present utility model, all interest fields of containing with the application's the scope of the claims and implementer, all do not depart from protection domain of the present utility model.
