Abstract
The invention discloses a template-root-adjustable sealing structure, which is easy to operate and especially applicable to the construction of reinforced-concrete anti-collision guardrails for bridges. The template-root-adjustable sealing structure disclosed by the invention comprises a sealing component arranged at the bottom of a template, the sealing component comprises an extensible steel belt which is formed by connecting at least two steel belts in series through a movable extensible device, the extensible steel belt is connected with a baseplate of the template through multiple sets of screw connecting assemblies which are arranged at intervals along the length direction of the extensible steel belt, and the bottom surface of the extensible steel belt is provided with a stripper rubber. After the sealing structure disclosed by the invention is used, mortar stripes are not required to be plastered below a template, other underbeds are not required to be filled below the template, and the template is directly supported on a cast bridge floor (plate surface), therefore, the labor and the time are saved, namely, both the construction cost is lowered and the time limit for a project is shortened, mortar leakage and root rotting can be prevented, meanwhile, the potential safety hazard is reduced, and the quality of concrete is improved. Compared with the traditional method, the quality, time limit for a project, safety and cost of the sealing structure are controlled better and reach higher levels.
Description
Technical field
The present invention relates to the formwork root hermetically-sealed construction in the realm of building construction, be particularly useful for the construction of bridge reinforcement concrete anti-collision guard bar.
Background technology
At present Collison fence for bridge concrete construction all adopts to build under template smears mortar band or filled plastics foam props up the conventional methods such as underbed, last for a long time, this method is first at formwork erection place, to repair and smear mortar band, formwork on mortar band again after mortar band reaches some strength, then concreting, form removal after concrete soil reaches some strength, after form removal, use the artificial mortar band of removing, time-consumingly not only increase construction cost but also incur loss through delay the duration, potential safety hazard is large, and rotten of root spillage is more, the inconsistent presentation quality that affects of concrete color after repairing, quality duration safety cost all cannot better be controlled,
Summary of the invention
The technical problem that the present invention is intended to solve is to provide a kind of ground easy and simple to handle formwork root adjustable sealing structure.
Formwork root adjustable sealing structure of the present invention comprises the seal that is positioned at template bottom, the seal comprises the scalable steel band being in series through movable telescopic device by least two steel bands, this scalable steel band is connected with the base plate of template along the spaced screw rod coupling assembling of scalable steel band length direction by many groups, and the bottom surface of described scalable steel band is provided with stripper rubber.
Further, on described base plate with described each screw rod coupling assembling in the suitable screw hole of screw rod be the bar shaped screw hole elongating along scalable width of steel band direction.
Further, described movable telescopic device comprises sliding sleeve, and this sliding sleeve is sleeved on the outside of the overlapped part of adjacent two steel band.
The invention has the beneficial effects as follows: without building, smear mortar band under template, also without fill other underbeds under template, directly watering the upper formwork of bridge floor (plate face), saving of work and time has reduced construction cost reduction of erection time again, can mortar leakage prevention and rotten, reduce potential safety hazard simultaneously, improved concrete quality.Quality duration safety cost is all better controlled compared with conventional method, and it is higher to be up to the standard.
Accompanying drawing explanation

The specific embodiment
For Collison fence for bridge concrete construction, as shown in Figure 1,3, on beam body 8, build two mutual opposed templates 7, the region between these two templates 7 is the die cavity of concreting.The bottom of template 7 is provided with seal, the seal comprises scalable steel band 1, scalable steel band 1 is connected with the base plate 4 of template 7 along the spaced screw rod coupling assembling 3 of scalable steel band 1 length direction by many groups, and the bottom surface of described scalable steel band 1 is provided with stripper rubber 2.Wherein, screw rod coupling assembling 3 is the structure that conventional screw rod 3a adds nut 3b, and this structure is used very general, can regulating base board 4 and scalable steel band 1 between distance.Scalable steel band 1 is in series through movable telescopic device by least two steel bands, and therefore, this scalable steel band 1 can stretch on its length direction.Movable telescopic device can adopt various structures, such as directly adjacent steel band wherein on a steel band, establish chute, make another piece steel band and this chute adaptation; Or, can adopt sliding sleeve 6, sliding sleeve 6 is sleeved on to the outside of the overlapped part of adjacent two steel band, this structure is more simple.Because scalable steel band 1 itself has certain elasticity and can also stretch on its length direction, therefore, when the External Force Acting lower time of scalable steel band 1 in the face of screw rod coupling assembling 3, this scalable steel band 1 just can deform in the direction perpendicular to scalable steel band 1, thereby the stripper rubber 2 that makes scalable steel band 1 bottom surface can adapt to the absolute altitude on ground to be changed, reach mortar leakage prevention and rotten object.In addition, on described base plate 4 with described each screw rod coupling assembling 3 in the suitable screw hole of screw rod 3a be the bar shaped screw hole 5 elongating along scalable steel band 1 width, like this, when unclamping nut 3b, just laterally (being the width of scalable steel band) regulates the position of the stripper rubber 2 of scalable steel band 1 and its below, so that stripper rubber 2 can adapt to the variation of surface state better, be also convenient to the installation setting of formwork root adjustable sealing structure simultaneously.
