Abstract
The invention discloses a baffle used for plugging gaps of the bottom portion of a guardrail clevis and a using method thereof. A baffle body is composed of three sections of baffles which are connected into a whole in sequence. The three sections of baffles are respectively an upper baffle, a middle baffle and a lower baffle. The cross section structure of the baffle body is shaped like a Chinese character 'zhi'. Through holes are evenly formed in the upper baffle and the middle baffle, wherein the bore diameter of each through hole is between 5mm and 10mm. The lower baffle is a plate body without through holes. The baffle body is pre-made of pentatricopeptide repeats (PPR) or other plastic materials which are good in hardness, toughness and weather fastness. The upper baffle and the middle baffle can respectively reverse around an intersecting line between the baffles. Rubber cushions with good elasticity are stuck on the intersecting line portion between the baffles. When the guardrail clevis is installed, a self-stable formwork system can be built, and the baffle used for plugging the gaps of the bottom portion of the guardrail clevis and the using method are beneficial for achieving dense filling of the gaps between the guardrail clevis and a flange plate in the process of pouring of concrete of a guardrail.
Description
Technical field
The present invention relates to the baffle plate that uses when closely knit filling construction is carried out in a kind of guardrail link plate of newly building bridge and frange plate gap and the using method of this baffle plate.
Background technology
The job practices of bridge concrete guardrail has three kinds, and the one, inside and outside side frames shuttering (needing to remove), then cast-in-place guardrail concrete; The 2nd, guardrail is integral prefabricated, and the bottom is reserved cast-in-place on a small quantity; The 3rd, template (not removing) is made with prefabricated concrete board in the outside, interior bogie side frame shuttering (needing to remove), then cast-in-situ concrete.Above-mentioned the first job practices, although guardrail and frange plate gapless, the field operation operation is intersected many, and the reinforcement cover qualification rate is low, and the template consumption is large, and speed of application is slow, and structural linetype capable of regulating amplitude is little.Above-mentioned the second job practices, the guardrail concrete quality is controlled, and the field operation operation is intersected few, and speed of application is very fast, but the guardrail globality is relatively poor, requires high and gap guardrail and frange plate is difficult to effective closely knit filling to the plant equipment at scene.The third above-mentioned job practices is between above-mentioned first and second two kinds of methods; prefabricated concrete board both as the concrete exterior sheathing of guardrail also as the permanent protection of guardrail; speed of application is very fast, and is less demanding to on-the-spot plant equipment, and the structural linetype adjustable range is large.
The third above-mentioned job practices is selected by domestic a large amount of bridge engineering, following several situation in use often occurs: (1) is linear for the outward appearance that guarantees bridge, need adjustment link plate position, part, cause the gap length of link plate and frange plate to differ; (2) Material Filling such as the multiplex batten in top in link plate and frange plate gap, rubble, mortar bar is as the bed die of guardrail cast-in-situ concrete; (3) the multiplex mortar in middle part and bottom in link plate and frange plate gap is filled, and not only takes time and effort, sealing effectiveness is poor also easily comes off; The water cross flow of (4) oozing out from link plate and frange plate gap is to the frange plate bottom surface, causes that the concrete surface slurry comes off, the exposed corrosion of steel bar of even accelerating of aggregate.
Summary of the invention
Task of the present invention is to solve the deficiency that prior art Bridge concrete guardrail job practices exists, and a kind of baffle plate for gap, shutoff guardrail link plate bottom is provided, and a kind of using method of the baffle plate for gap, shutoff guardrail link plate bottom.
Its technical solution is:
A kind of baffle plate for gap, shutoff guardrail link plate bottom, baffle body is comprised of three sections baffle plates that are linked to be successively an integral body, three sections baffle plates are respectively overhead gage, middle baffle plate and lower baffle plate, the cross-sectional configuration of baffle body is similar to " it " font, overhead gage and middle baffle plate all offer the through hole that equally distributed aperture is 5～10mm, and lower baffle plate is without the through hole plate body.
The width of above-mentioned baffle body goes out greatly 20～50mm than the maximal clearance between guardrail link plate and frange plate, and the free end of lower baffle plate is provided with horizontal brace, and horizontal brace can embed in the notch that is opened in guardrail link plate lower inside.
Above-mentioned baffle body be by PPR or other hardness, toughness and weatherability all good plastic materials be prefabricated into.
Above-mentioned overhead gage and middle baffle plate can be respectively reverse around the intersection between baffle plate, and the intersection position between baffle plate is pasted with the good rubber pad of elasticity.
A kind of using method of above-mentioned baffle plate for gap, shutoff guardrail link plate bottom comprises the following steps:
A reserves the notch of certain depth and width in the lower inside of guardrail link plate, in horizontal brace embedding notch by lower baffle plate, baffle body is fixed, when the guardrail link plate is installed, overhead gage and middle baffle plate can be out of shape along with guardrail link plate and dwindling of frange plate spacing and adapt to it, in order to guarantee the sealing up and down in guardrail link plate and frange plate gap;
B carries out guardrail concreting after completing steps a, the concrete that a part of particle diameter is little in casting process enters three sections gaps between baffle plate by the through hole on overhead gage and middle baffle plate, realizes the closely knit filling in guardrail link plate and frange plate gap.
In above-mentioned steps a, an end of the close frange plate of overhead gage is lower than the end near the guardrail link plate, and the leading edge of overhead gage is near guardrail outermost embedded ribs, and the top of lower baffle and the lowermost end of frange plate distance are controlled in 20～50mm scope; At overhead gage and intersection position between middle baffle plate and middle baffle plate rubber pad together with all paste at the intersection position between lower baffle plate, in order to guarantee the effective sealing of baffle body and frange plate and guardrail link plate when adjusting the gap of frange plate and guardrail link plate.
The present invention has following useful technique effect:
The present invention can build the template system of self-stabilization when the guardrail link plate is installed, be particularly conducive to the closely knit filling that realizes guardrail link plate and frange plate gap when guardrail concreting.
