Background
Modern large stadiums and garden modeling need to build large stairs, large roof boards and large concrete structural modeling, irregular concrete member construction is often needed, the upper opening of the concrete member is a regular plane, the lower opening of the concrete member is composed of pyramid tops formed by converging three or more surfaces, a plurality of templates are needed to be spliced into corresponding pyramids to cover the pyramid tops of the concrete member, the templates are not parallel to the templates of the regular plane of the upper opening, the pyramid-shaped template group needs to be reliably reinforced to ensure the quality of the member, and the prior template reinforcement usually adopts the following methods:
1. the periphery of the steel pipe is reinforced, namely the upper part and the lower part of the floor slab or the rectangular concrete member are firmly hooped by the hoops and the steel pipes to reinforce the template, and the method has the advantages of large consumption of steel pipe material, high cost and long construction period;
2. the upper opening of the template is firmly clamped by adopting a step tightening tool, the method is suitable for the components with smaller height and capable of being completely fixed from the upper opening of the template of the component, and the components with higher components are only clamped from the upper opening, so that the lower part of the template can generate a die expansion phenomenon to influence the quality of the components;
3. the method is simple by using the iron wire counter-pulling template, but the template is easy to expand the membrane and leak the slurry when the concrete is poured and tamped because the iron wire has too high flexibility;
4. the common split bolt is designed into two parallel mountain-shaped clamps, the upper opening and the lower opening of the irregular concrete member are not parallel to the pulling surface, the split bolt cannot form vertical pulling force on the formwork, and the formwork at the end part of the pyramid top of the concrete member bears the lateral pressure of the concrete and the pulling force of the split bolt to form an inclination angle, so that the formwork is easy to run.
When the reinforcement of the traditional templates cannot achieve the best effect on irregular concrete members, particularly the reinforcement of the top of the pyramid combined by the templates is not firm, so that the phenomena of serious slurry leakage, template running, irregular and straight concrete member corners and the like are caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a defect in order to solve prior art existence that is used for the counter-pull screw rod of irregular concrete component template.
Realize the utility model discloses purpose technical scheme is:
the opposite pulling screw for irregular concrete member formwork has one end screwed and provided with high strength nut, and unlike available technology, the opposite pulling screw has one barb protecting structure in the other end and the barb is set in the end of the opposite pulling screw,
the protective support is a pyramid protective angle formed by steel plates, the shape of the pyramid protective angle is matched with the pyramid top of the concrete member, the pyramid protective angle can be movably sleeved on the oppositely-pulling screw rod through a through hole formed in the top end of the pyramid protective angle, the bottom of the pyramid protective angle faces to the threading end of the oppositely-pulling screw rod, the top end of the pyramid protective angle faces to the barb end of the oppositely-pulling screw rod, when the protective support works, the barb clings to the outer surface of the pyramid protective angle, and the pyramid protective angle wraps the surface of the pyramid top end formed.
Furthermore, the thickness of the steel plates forming the pyramid angle bead is not less than 2 mm.
Furthermore, the bottom edge of the corner protector forming the pyramid is not less than 100 mm.
Further, the barb length is not less than 50 mm.
Furthermore, the number of the barbs is two, and the barbs are symmetrically arranged on two sides of the end of the counter-pulling screw rod.
Furthermore, one end of the mantle fiber of the split screw is also provided with a mountain-shaped buckle.
The utility model discloses when using, at first use the template to build the pyramid according to the pyramid top shape of concrete component, install the pyramid angle bead to the pyramid top of template combination, then pass the top of pyramid angle bead, the pyramid top of template combination in proper order with the mantle fiber end of the counter-pull screw rod of present case to pass the hole in the template of concrete component rule plane perpendicularly, with barb clench pyramid angle bead, hold mountain-shaped card, the nut that excels in and screw up, taut template in the concrete component. Before inserting the split screw, the plastic sleeve is installed at the corresponding position, and the split screw can be recycled when the template is detached.
The utility model discloses the structure adopts the barb to protect and holds in the palm the structure, can carry out good fixed action to the template top of pyramid concrete component, the pyramid angle bead compresses tightly on the template face under barb and mantle fiber bolt combined action, the template top of constituteing each face of pyramid all is wrapped up by the pyramid angle bead, be difficult for running the mould when pouring and tamping the concrete, effectively reduce pyramid top thick liquid phenomenon that leaks, this processing is simple to the lag screw, the barb can directly adopt current split bolt and the processing of steel bar waste to form, the prism angle bead also can adopt old and useless steel sheet welding to form, the cost of manufacture is low, satisfy energy saving and consumption reduction requirement, simple to operate simultaneously, the concrete component shape that the back mould came out is in the same direction as straight, impression quality promotes greatly.
