Abstract
The utility model discloses a kind of braced structures for constructing tunnel, comprise and support vertical beam, support platform, support bar, support switch block and gripper shoe, described support platform is positioned at and supports above vertical beam; Described support bar has many and is located at side by side in support platform, and the top of support bar is provided with ball-type groove; Described support switch block one end is provided with the bulb with the ball-type groove match of described supporting bar top, and the other end is curved surface, and this curved surface is connected with the gripper shoe of arch; The utility model is uniform force in constructing tunnel process, and reliability is high, is easy to mounting and adjusting.
Description
Technical field
The utility model relates to constructing tunnel, particularly relates to a kind of braced structures for constructing tunnel.
Background technology
When carrying out constructing tunnel, needing, braced structures is set in tunnel and supports, to guarantee the safety in work progress.Braced structures needs to arrange many support bars according to the radian of inverted arch for the support that tunnel invert provides, and support bar is connected with supporting seat by hinge, by the angle between hinge change support bar and supporting seat, inverted arch carried out to the support of varied angle.This braced structures is comparatively complicated, and hinge becomes a ring of most fragile in overall structure, once hinge crumbles, just likely directly causes tunnel cave.
Utility model content
Utility model object: the utility model object is to provide a kind of uniform force, and reliability is high, is easy to the braced structures for constructing tunnel of mounting and adjusting.
Technical scheme: a kind of braced structures for constructing tunnel, comprises and supports vertical beam, support platform, support bar, support switch block and gripper shoe, and described support platform is positioned at and supports above vertical beam; Described support bar has many and is located at side by side in support platform, and the top of support bar is provided with ball-type groove; One end that described support switch block is connected with support bar 20 is provided with the bulb with the ball-type groove match of described supporting bar top, and the other end is curved surface, and this curved surface is connected with the gripper shoe of arch.
Further, described support bar is Height Adjustable Telescopic rod structure.
Further, the described end face of support switch block and the mating shapes of gripper shoe.
Further, the two ends of described gripper shoe are provided with jack.
Further, the width of described support vertical beam is identical with the width of support platform bottom.
Further, the width of described support platform bottom is less than the width on top.
Beneficial effect: compared with prior art, the utility model arranges the support bar and support switch block that cooperatively interact, support switch block to rotate in the ball-type groove of support bar thus coordinate the angle in the tunnel be supported by it, easy to adjust, and the stress point of spherical syndeton is positioned at the centre of sphere on ball top all the time, support switch block and forward various angle to, its power of bearing is all pass to support bar vertically downward, this just makes integrally-built stressing conditions be consistent, thus improves the reliability of braced structures.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing of A in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
As shown in Figure 1-2, the described braced structures for constructing tunnel, comprises and supports vertical beam 10, support bar 20, support switch block 30 and gripper shoe 40;
Support platform 11 is positioned at the top supporting vertical beam 10, and supporting vertical beam 10 is rectangle, and support platform 11 is isosceles trapezoid, and the length of support platform 11 minor face is equal with the length supporting vertical beam 10, is located on the bottom surface, tunnel 101 of tunnel 100 central authorities;
The top of support bar 20 is provided with ball-type groove 21, and support bar 20 has five and is located in support platform 11 side by side; Support bar 20 is set to adjustable for height Telescopic rod structure, support bar 20 is first reduced to the shortest height before supporting, then be fixed on to support after in vertical beam 10 and start upwards to regulate height until contact with gripper shoe 40, adopt such structure that installation can be made more convenient.Wherein, stretching structure realizes by a pair screw thread pair, by the flexible height of threaded adjustment support bar 20;
One end that support switch block 30 is connected with support bar 20 is provided with the bulb matched with the ball-type groove 21 on described support bar 20 top, and the other end is curved surface, and this curved surface is connected with the gripper shoe 40 of arch; Gripper shoe 40 is for below tunnel 100 and its two ends are supported on bottom surface, tunnel 101 by jack 41, jack is set and carrys out the installation that supported plate 40 can facilitate early stage, gripper shoe 40 is inserted tunnel 100 and is deployed in after below tunnel 100, by two ends jack upwards jack-up, gripper shoe 40 just can be fitted with upper end, tunnel 100 wall, and the middle part of arch support plate 40 is from top to bottom supported by above-mentioned supporting seat switch block 30, support bar 20 and support vertical beam 10 successively; Support the end face of switch block 30 and the mating shapes of gripper shoe 40, adopt the design of matched that the bottom surface of the end face of support switch block 30 and gripper shoe 40 can be made more to fit, support more firm;
The section shape of gripper shoe 40 and the shape of cross section in tunnel 100 match, and gripper shoe 40 is designed to mate with the shape of cross section in tunnel 100 and can makes the stressed more even of gripper shoe 40, thus improves the reliability of braced structures further.
