Summary of the invention
Technical problem to be solved in the utility model is, a kind of construction formwork integral type connecting pin is provided, and it connects and dismantles simply, fast, can be repeatedly used.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of construction formwork integral type connecting pin, has bearing pin, its technical scheme is that described construction formwork integral type connecting pin also has taper pin, the pin sheet, above-mentioned bearing pin links together taper pin and pin sheet, taper pin has and is tubular pin cap, be tubular shank, the outer end of shank has chamfering, have a square groove that runs through shank on the shank, this square groove is at the chamfered end opening of described shank, shank is provided with perpendicular to the opening direction of square groove and runs through the pin shaft hole of shank at described square groove position, the both ends of described pin sheet are circular arc, have the chute that runs through the pin sheet on the pin sheet, this chute is divided into the clamp segment that is positioned at its centre, be positioned at two arc sections at its two ends, two changeover portions that described clamp segment is connected to two arc sections, the center line of the clamp segment of chute is with respect to angle of longitudinal centre line inclination of pin sheet, the center of arc of two arc sections of chute is all on the longitudinal centre line of pin sheet, the pin sheet passes the square groove on the shank of taper pin, and bearing pin passes the chute on shank and the pin sheet by the above-mentioned pin shaft hole on the taper pin and taper pin and pin sheet are connected as a single entity.
In the technique scheme, the profile of described pin sheet is symmetrical structure with respect to the longitudinal centre line of pin sheet, and described chute is centrosymmetric with the longitudinal centre line mid point of pin sheet.
To sell first sheet when the utility model uses and be rotated into unanimously with the axial direction of taper pin, and then pass construction formwork limit rib connecting hole with taper pin, will sell at last sheet rotation 90o wedging and get final product, will sell that sheet pounds out is detachably.All parts of the utility model all link together, and have in use reduced the part collapsing loss, adopt the wedge type clamping mode, and connection and dismounting are simple, quick, can be repeatedly used.
