Abstract
The invention relates to a manufacturing process of expansion joints and expansion joints of a bridge anti-collision guardrail. When the anti-collision guardrail template is installed, the template splicing joints are adjusted to the designed deformation joint positions, steel plates are inserted into the splicing joints, and the template splicing joints are connected with the guardrail template into a whole through bolts. And then adhering foam boards on two sides of the steel plate according to the reserved deformation seam width, processing the foam boards into a guardrail shape, and coating lubricating oil on the contact surface of the steel plate and the foam. When the template is disassembled, the steel plate is taken out upwards, and a standard deformation joint is formed. The process has the advantages that the process is convenient to install and remove the template, the template can be recycled, the cost is saved, the manufactured deformation joint and the expansion joint are straight and attractive, the manufacture is convenient and easy, and the process is rapid and reliable.
Description
Technical field
The invention belongs to bridge construction engineering field, relate to the reservation anticollision barrier, the manufacture craft of especially a kind of Collison fence for bridge shrinkage joint, deformation joint.
Background technology
For preventing anticollision barrier stress deformation cracking, (common 2～5m) need establish deformation joint one to anticollision barrier, and in the position of corresponding deck expansion joint, this guardrail also will be provided with the shrinkage joint every a determining deviation.Because the spacing of deformation joint is shorter, the length of one-time-concreting guardrail is longer, needs to adopt a kind of device to reserve deformation joint, shrinkage joint.At present Collison fence for bridge shrinkage joint, deformation joint adopt plank to reserve usually, not only waste material, reinforce difficulty, the colleague is shifted when stamped concrete easily, influences attractive in appearance; And plank is embedded in the concrete the flexible effect of influence.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, the manufacture craft of a kind of Collison fence for bridge shrinkage joint, deformation joint is provided, the shrinkage joint of this technology made and deformation joint high conformity, and make efficiency height do not influence the operation of building of guardrail.
The present invention realizes that the technical scheme of purpose is:
The manufacture craft of a kind of Collison fence for bridge shrinkage joint, deformation joint, it is characterized in that: step is:
⑴ deformation joint steel plate is by the guardrail template assembly cross dimensions processing of design, is shaped on bolt hole at the outline of deformation joint steel plate as uniform interval, and the made bolt hole of this bolt hole and guardrail template is corresponding, makes a dismounting hole for hoist in the upper end of deformation joint steel plate;
⑵ select cystosepiment also to be processed into the guardrail shape according to the width of guardrail reservation deformation joint, and two cystosepiments before the guardrail template is installed, are placed in the position of deformation joint in advance, and the centre of two cystosepiments is according to the thickness reserved location of deformation joint steel plate;
⑶ install the guardrail template, and between cystosepiment the deformation joint steel plate is installed, and guardrail template and deformation joint steel plate adopt bolton to be integral, and cystosepiment and deformation slit formwork is closely connected, deformation joint steel plate and cystosepiment contact surface coating lubricating oil;
⑷ build the guardrail concrete between the guardrail template;
⑸ after the concrete setting, remove the guardrail template, hang out deformation slit formwork, promptly form the deformation joint of one standard from the dismounting hole for hoist of deformation joint steel plate.
And, the two sides coating lubricating oil of the deformation joint steel plate of described step ⑴.
Advantage of the present invention and good effect are:
1, this technology template is installed, is removed conveniently, template can reuse, and saves cost, adopts steel plate to reserve deformation joint, shrinkage joint, steel plate two sides coating lubricating oil, deformation joint is wide to paste cystosepiment in the steel plate both sides according to reserving then, and is processed into the guardrail shape in this position, and presses the bolt position prepared screw-bolt hole of guardrail template, adopt bolt and template to fix, tear open when holding template, upwards take out steel plate, promptly form the deformation joint of one standard.
2, the deformation joint of this technology made and shrinkage joint are straight, attractive in appearance, and be easy to make easy, fast and reliable, and employed template can be used as bulkhead simultaneously, have the effect of reinforcing that is equipped with concurrently, reservation seam hollow, the effect of the distortion that really reaches.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail by embodiment:
The manufacture craft of a kind of Collison fence for bridge shrinkage joint, deformation joint, step is:
⑴ be processed into guardrail 6 lateral dimension sizes with deformation joint steel plate 2, is shaped on bolt hole 5 at the outline of deformation joint steel plate as uniform interval, and the made bolt hole of this bolt hole and guardrail template 1 is corresponding, makes one in the upper end of deformation joint steel plate and removes hole for hoist 4;
⑵ reserve the width of deformation joint according to guardrail, select the cystosepiment 3 of suitable thickness, also be processed into the guardrail shape, with two cystosepiments before the guardrail template is installed, be placed in the position of deformation joint in advance, the centre of two cystosepiments is according to the thickness reserved location of deformation joint steel plate;
⑶ install the guardrail template, and by the position of design the deformation joint steel plate is installed between cystosepiment, and guardrail template and deformation joint steel plate adopt bolton to be integral, and cystosepiment and deformation slit formwork is closely connected, and the deformation joint steel plate is installed preceding two sides coating lubricating oil;
Processing guardrail template is planned the every joint length of template, guarantees that the form joint position is corresponding with the deformation joint position.
⑷ built the guardrail concrete before the guardrail template;
⑸ after the concrete setting, remove the guardrail template, hang out deformation slit formwork, promptly form the deformation joint of one standard from the dismounting hole for hoist of deformation joint steel plate.
The foregoing description only is a preferred implementation of the present invention, and in addition, the present invention can also have other implementations.Need to prove that under the prerequisite that does not break away from the present invention's design, any conspicuous improvement and modification all should fall within protection scope of the present invention.
