[0030] Specific implementation method: when pouring the cement square column, determine the size of the cement square column in advance, adjust the positions of the first template 1 and the second template 2, and insert the rotating rod 8 into the concave hole on the surface of the gear 6 through the third through hole. In the groove, operate the rotating rod 8 to rotate according to the required size, the rotating rod 8 drives the gear 6 to rotate, the gear 6 meshes with two racks 7, and the two racks 7 respectively drive the first template 1 and the second template 2 to move toward each other , the horizontal parts on the first template 1 and the second template 2 slide out along the hollow plate 3, and the first spring 5 is stretched. The first template 1 and the second template 2 are controlled to maintain a fixed position, and the cement slurry is poured inside to complete the pouring of the cement square column.
[0031] After the cement square column is fixed and formed...

The invention discloses a cement concrete square column formwork convenient to disassemble, and relates to the technical field of building formworks. The cement concrete square column formwork convenient to disassemble comprises a first formwork, a second formwork and a hollow slab; horizontal parts of the first formwork and the second formwork both penetrate through the hollow slab in a sliding mode; a first spring is fixedly connected between the ends, arranged in the hollow slab, of the first formwork and the second formwork; limiting mechanism is installed in the hollow slab; fixing plates are installed on the outer side faces of vertical parts of the first formwork and the second formwork; cavities are formed in the fixing plates; trapezoidal blocks are slidably connected with the interiors of the cavities; a plurality of first through holes are formed in the rear side walls of the fixing plates; supporting rods are slidably connected with the interiors of the first through holes; second through holes are formed in the positions, right opposite to the first through holes, of the vertical parts of the first formwork and the second formwork; and the supporting rods abut against the inclined faces of the trapezoidal blocks. The problems that in the prior art, a formwork is installed and fixed through cement nails, the interior of a combined structure is unstable, and demolding is difficult are solved, operation is easy and convenient, and practicability is high.
Description
technical field [0001] The invention relates to the technical field of building formwork, in particular to a cement concrete square column formwork which is easy to disassemble. Background technique [0002] In the construction process of reinforced concrete in construction projects, especially when pouring square concrete columns, the formwork is usually spliced and assembled into a square column formwork in advance, and cement is poured into it, and the formwork is removed when the cement strength meets the requirements for demoulding. [0003] When the existing square column formwork is used, cement nails are usually used to install and fix the formwork. The interior of the combined structure is very unstable, and it is prone to the problem of difficult demoulding, and the operation is inconvenient, which directly affects the square column. Quality and aesthetics. Contents of the invention [0004] The purpose of the present invention is to provide a cement concrete ...
