Embodiment Construction

[0007] As shown in the figure, it is a loose-leaf internal corner template, including two template bodies 2 and 8 intersecting at the sidelines, and a hinge 1 is provided at the intersection of the two template bodies 2 and 8, and the two template bodies 2 and 8 can be Rotate around the hinge 1 to change the angle. Nuts 4 and 6 are hinged through the pin shafts 3 and 7 on the back of the template body 2 and 8. The threads of the two nuts 4 and 6 are positive and the other negative. The double-threaded adjusting rod 5 of anti-teeth can change the angle between the template body 2 and 8 by rotating the double-ended threaded adjusting rod 5 .

Abstract

The invention discloses a loose leaf type inside corner mould plate, belonging to the architectural mould plate field. The loose leaf type inside corner mould plate comprises two mould plate bodies, intersecting curve of which is provided with a hinge; the back surface of each mould plate body is hinged with a nut by a pin shaft, screw threads of the two nuts are opposite in direction, a double thread adjusting lever with positive threads and negative threads is connected between the two nuts. In the invention, by turning the double thread adjusting lever, the included angle between the two mould plate bodies can be increased or reduced, thereby being capable of adapting to vertical moulds in inside corners with different angles; while demoulding, by turning the double thread adjusting lever, the included angle between the two mould plate bodies is reduced, and the mould plate can be conveniently taken off. Compared with the prior art, the mould plate of the invention has the advantages of being used in a plurality of places, facilitating the standardized production, saving cost , being conveniently used and being capable of loosening the mould plate from the single side, along with easy demoulding and convenient assembly and disassembly.

Description

technical field [0001] The invention relates to an appliance for building construction, in particular to a formwork for pouring concrete. Background technique [0002] In the prior art, formwork is needed when pouring concrete to form it. The inner corner formwork is mainly used for the inner corner part of pouring concrete, and its shape is generally a right angle or an acute angle. The existing inner corner formwork mainly includes two formwork bodies, and the two formwork One side of the body is fixed to intersect. This formwork needs to be taken off as a whole when demoulding, and the formwork disassembly is very difficult, and the angle is difficult to adjust. A type of internal corner requires a formwork, which is expensive and inconvenient to use. Contents of the invention [0003] The purpose of the present invention is to provide a loose-leaf internal corner formwork, which has low cost and is easy to use. [0004] The purpose of the present invention is achiev...
