Abstract
The utility model discloses a device used for strengthening concrete column and shear wall mould, which comprises two locating blocks 1 and a resisting device 3, wherein, the two locating blocks 1 are positioned with one side being a plane or an arc surface and the other side having a bulge at the middle part and inside the bulge a cross through hole 7 with a wedge strip 2 drilling through the transverse through hole is provided; the resisting device 3 composed of a rigid tube with a ringent middle part is arranged with the inside of the rigid tube provided with an axial direction hollow screw stem 5, one end of the rigid tube equipped with a nut 6 fitting close with the screw thread of the screw stem 5 and one side of the screw stem provided with a fastener 4. The utility model has the advantages of simple structure, low manufacture cost, convenient use, high work efficiency and reclaiming for reuse.
Description
Technical field
The utility model relates to a kind of device of reinforcing construction formwork, relates in particular to the device of a kind of reinforced concrete column, shear wall formwork.
Background technology
All need to be provided with earlier template at building trade placing of concrete post especially shear wall, mostly the construction worker is to carry out position and fastening by iron wire or other fixture when mounting template at present, to prevent the template deformation displacement, influences construction quality.Locate formboard fastening with iron wire and cause waste easily, increase construction cost, can not guarantee construction precision; It is fastening to adopt screw rod to position when shear wall formwork is installed, and the body of wall deviation takes place easily, and operation is numerous and diverse, efficient is low, moreover it is less more to position fastening required accessory with screw rod, is difficult for reclaiming reusing, and increases construction cost.
Summary of the invention
The purpose of this utility model provides a kind of device that makes things convenient for reinforced concrete column, shear wall formwork.
The designed technical scheme of the utility model is: be provided with two locating pieces, one side of locating piece is plane or arcwall face, the plane can increase the contact surface of locating piece and template, arcwall face can be pressed in the Circular Rigid pipe on the template and that template is carried out the large tracts of land location is fastening, the opposite side central protrusion of locating piece and within it portion be provided with cross phase through hole, have a wedge-shaped bar to pass transverse holes in the cross phase through hole, this wedge-shaped bar can fasteningly be passed the reinforcing bar of the axial hole of locating piece; Other is provided with a chest expander, this chest expander is made up of the rigid pipe of an intermediate openings, be provided with the screw rod of an axial hollow in the inside of rigid pipe, one end of rigid pipe is provided with a nut that matches with the screw rod rib-loop, swivel nut can make the screw rod displacement, side at screw rod has securing member, can fasteningly pass the reinforcing bar of screw rod.When using, reinforcing bar is passed template and reinforcing bar is fastening with locating piece, the other end of reinforcing bar passes another locating piece and chest expander, fastening with the securing member on the screw rod reinforcing bar, swivel nut carries out the pull reinforcing bar and puts in place by template, use another locating piece that reinforcing bar is fastening then, unclamp the screw rod securing member, withdraw from chest expander and can reach the purpose of reinforcing locating template.
The apparatus structure that is used for reinforced concrete column, shear wall formwork provided by the utility model is simple, and cost of manufacture is low, and is easy to use, high efficiency, recyclable repeated use.
