Description
Technical field
The utility model relates to the technical field of construction of the protective device of bridge, particularly for the concrete anticollision of bridge
The template system of guardrail.
Background technique
In the infrastructure of traffic, bridge is a kind of very common building structure, in river, mountain valley, existing road
Top build road when, all can use arrive bridge structure.In order to avoid vehicle falls from the edge of bridge, then, bridge
The anticollision barrier as made of concreting can be all arranged in the marginal position of beam.Before carrying out the pouring of concrete, elder generation is needed
Install the template system of anticollision barrier.Template system mainly includes that inner side template, outboard template and formwork reinforcement mechanism, template add
Gu mechanism includes split bolt, reinforcing rod, inclined support bar；Inner side template and outboard template are oppositely arranged, inner side template and outside
The cavity for being used for casting concrete is formed between template, one of inner side template and outboard template far from cavity is arranged in reinforcing rod
Side, and reinforcing rod being strained and fixed also cross inner side template and outboard template using split bolt, thus make inner side template and
Outboard template is relatively fixed, and is able to bear lateral pressure when concreting, is propped up by inclined support bar inner side template
Then support passes through split bolt and the adjustable outside of reinforcing rod so that the vertical tilt angle of inner side template be made to meet the requirements
The vertical tilt angle of template also complies with requirement.
The both ends of split bolt are equipped with the buckle for the reinforcing rod that is fixed, due to split bolt need also cross
Inner side template and outboard template, then, the buckle of one end on split bolt need to install again after split bolt passes through template
It up, is in the prior art usually that from outboard template side, side template side carries out penetrating split bolt inwardly by split bolt,
Then buckle is mounted on split bolt in the side of inner side template, installation buckle more convenient in this way.But due to outside
Template closes on the edge of bridge, and worker needs to observe the position of through-hole on outboard template when split bolt is penetrated outboard template
It sets, then, needs worker to body is leant out on the outside of bridge to operate, and then make the operation of worker there are biggish safety
Hidden danger.Inclined support bar is to be followed closely inclined support bar in bridge by using steel nail after adjusting the tilt angle of inner side template
It is fixed on the concrete of beam, when removing inclined support bar, needs to extract steel nail out of concrete, caused tiltedly
The dismounting of support rod is more troublesome；Meanwhile when pouring if necessary to the tilt angle of adjustment template, need inclined support bar
Fixation is re-started after dismounting, causes adjustment to operate also more time-consuming, it has not been convenient to be operated.
Summary of the invention
This programme is intended to provide a kind of template system of concrete anti-collision guard bar for bridge, to solve in the prior art
The outboard template of the concrete anti-collision guard bar of bridge is inconvenient to carry out the fixed problem of installation.
The technical solution of the utility model are as follows: the template system of the concrete anti-collision guard bar for bridge, including by inside
The template group of template and outboard template composition, the two sides of template group are equipped with lateral reinforcing rod, are additionally provided in template group and laterally pass through
The Screw arbor with nut at both-ends of template group is worn, Screw arbor with nut at both-ends is equipped with the buckle group for the reinforcing rod that is fixed, and buckle group includes inside card
Button and outside buckle, inside buckle be sleeved on Screw arbor with nut at both-ends, inside buckle far from inner side template side be equipped with to draw spiral shell
The lower end of the nut that bar is threadedly coupled, the outside buckle slidably connects sliding block, and sliding block is hinged with outboard template, outside buckle
It is equipped with the threaded hole being threadedly engaged with Screw arbor with nut at both-ends, outside buckle is axial parallel with threaded hole along the glide direction of sliding block.
Inner side template and outboard template: being separately positioned on the two sides of the framework of steel reinforcement of anticollision barrier by working principle, by position
Reinforcing rod in outboard template side is placed on the buckle of outside, then from the side of inner side template towards the side of outboard template
Screw arbor with nut at both-ends is penetrated, when Screw arbor with nut at both-ends is pierced by outboard template, outside is pulled up and buckles one end far from sliding block, make outer
Threaded hole on the buckle of side is opposite with Screw arbor with nut at both-ends, and rotation Screw arbor with nut at both-ends makes to realize Screw arbor with nut at both-ends in Screw arbor with nut at both-ends insertion threaded hole
With the threaded connection of outside buckle, then the nut on the side of inner side template rotation Screw arbor with nut at both-ends, drives Screw arbor with nut at both-ends
Outside buckle and inside buckle move closer to, so that the reinforcing rod of template group two sides is driven gradually to clamp template group, realization pair
The fixation of template group.
Compared with prior art, be the advantages of this programme: Screw arbor with nut at both-ends wears outside side template from the side of inner side template
Side and template group is fixed, so that worker be made to be not necessarily to penetrate Screw arbor with nut at both-ends toward body is chosen on the outside of bridge, from
And the installation for facilitating outboard template is fixed, and then improves the safety of worker operation.
Further, the penetrating end of the threaded hole is in horn-like.The penetrating end of threaded hole is arranged to it is horn-like, thus
Screw arbor with nut at both-ends forms guiding role when penetrating threaded hole, and Screw arbor with nut at both-ends is facilitated to penetrate in threaded hole.
It further, further include support frame, support frame as described above includes pedestal, upright bar and brace, under the upright bar and brace
End is hinged with pedestal, and the upper end of brace and the top of upright bar are hinged, and brace is adjustable telescopic bar, and upright bar and inner side template can
Dismantling connection is removably connected with clump weight on the pedestal.By setting pedestal, upright bar and brace, make pedestal, upright bar and tiltedly
Bar forms a triangular support system；By the way that brace is arranged to adjustable telescopic bar, the convenient length by adjusting brace
To control the verticality of upright bar, and then the purpose that the verticality of inner side template is adjusted in realization；Counterweight is set on pedestal
Block, increases the weight of support frame, so that pedestal be made to be not susceptible to move.Lateral support is carried out to inner side template by support frame,
To be conducive to improve the stability of template group, while also facilitating and the verticality of inner side template is adjusted.
Further, the brace include coaxial arrangement sleeve, first support bar and second support bar, first support bar with
Sleeve rotation connection, second support bar are connect with bush whorl.By rotational sleeve, make between sleeve and second support bar in spiral shell
It can extend and shorten under the action of line, and then conveniently be adjusted.
Further, the side of the separate inner side template of the outboard template is equipped with vertical bar, and the upper end of bar is fixed
It is connected with lateral connecting rod, connecting rod is hinged with upright bar, and the angle of bar and connecting rod is less than 90 °.By the way that bar, benefit is arranged
Outboard template can be fixed temporarily with bar when not reinforcing, avoid outboard template toward the outer inclination of bridge
.
Further, the bottom of the pedestal is fixedly connected with several spike-tooths.By the way that spike-tooth is arranged, pedestal can be with by spike-tooth
Increase the frictional force between bridge, so as to improve the stability of pedestal placement.
