Description

Pillar formwork {FIXING DEVICE FOR MOLD CONCRETE COLUMN OF CONSTRUCTION}

The present invention relates to a column formwork fixing device, and more specifically, to form a screw fastening protrusion on the outer surface of the square pipe-type fastening rod, and constitutes a screw fastening hole formed with a screw fastening groove on the inner surface to be fastened to the screw fastening rod, In the construction of the square formwork, which is cross-bonded to each other, to secure the outer surface of the column formwork, the work efficiency is improved and the assembly efficiency is improved. It is a pillar formwork fixing device that can be easily work alone by inducing cost reduction by manpower saving.

In general, the formwork used when building a concrete column structure is usually a wooden panel, which is made depending on the combination method of fitting the wooden panel one by one.

Therefore, not only is the problem that the work takes a long time to create and dismantle the form, but also a huge loss caused by the massive consumption of the once used parts, such as wire or nails, when making the form.

In addition, the wood formwork has a short lifespan that can be repeatedly used because of its weak durability in terms of material properties, and has a drawback in that it is made of relatively expensive wood and has low economical efficiency.

Accordingly, in recent years, a tendency is to install metal formwork by using a metal plate instead of wood formwork and by adding a reinforcing material other than that.

On the other hand, when constructing the pillars of the building to form a square frame of the pillars to form the concrete to support the outside of the formwork in order to maintain the shape of the square frame until deformation after drying.

Conventionally used formwork fixing device is to support the round bar or lumber on the outside of the form after completing the rectangular frame with the formwork, because the round bar or lumber must be fastened with a wire, etc., workability and productivity are reduced, and also cross each other Round bar or lumber has the problem of not firmly pressing the formwork because it depends on the tightening of the wire.

In addition, the angle of the round bar or lumber can be changed during the process of tightening the wire, so that if the round bar or lumber does not cross perpendicular to each other, the bearing force is not evenly distributed in the width direction of the formwork to surround the four sides of the column. There was a risk that one side might burst out of the formwork.

In addition, simply supporting the round bar or lumber in the horizontal direction with respect to the pillar is not able to firmly support the formwork so that it is inclined from the sides of the form or round bar and the lumber, in which case it takes up a lot of space and There was a problem that could be an obstacle, obstruct the traffic of the worker and cause a safety accident.

In order to solve this problem, techniques for fixing the column pillars have been proposed.

As an example, a formwork supporting device for a building pillar, which was applied as a utility model application No. 20-2007-0005569, was conceived, which supports the outside of the formwork horizontally, and at one end thereof, a plurality of fastening holes are formed at regular intervals. A pair of horizontal beams having an inclined surface on the other end, and a plurality of fastening holes corresponding to the horizontal beams are formed at a predetermined interval and coupled to the horizontal beam in a state intersected with the horizontal beam in the vertical direction. A pair of longitudinal beams and a U-shaped connecting bracket which is installed at the intersection of the horizontal beam and the vertical beam to fix the connecting portion and has a handle for position adjustment at the rear, and is inserted into the connecting bracket in the vertical direction. It consists of a fixing clamp and a wedge inserted into a space formed by the inclined surface of the horizontal beam and the inner portion of the connecting bracket.

As another example, a fixed structure for pillar formwork has been devised Patent No. 10-0860831, which is formed extending from one end of the band body and the band body disposed around the pillar form, having a receiving space therein A pair of main bands including a guide band and the other end of the main band located opposite to the guide band are installed to face up and down to have a working space therein, and a plate bar inclined adjacent to the main band is installed. An opening for opening the working space to the outside is formed on the opposite side of the plate bar, a guide plate having a guide hole formed in the longitudinal direction adjacent to the opening, a hinge shaft that slides along the guide hole; And a guide body extending in the cross direction from the body and the body assembled to the hinge axis, A pull nut having a threaded groove formed therein and one end connected to the main band in parallel to the main band through the hinge shaft while receiving the pull nut, and rotated, and the other end is inserted into the inner receiving space of the guide band to form a pillar. A pair of connecting bands arranged around the other end of the main band and the other end of the main band and a fastening element to maintain and maintain the assembled state of the assembled guide band, and mounted on the plate bar and rotated, the guide member of the pull nut It is composed of fastening bolts which are screwed together to adjust the spacing of the connection bands.

However, these conventional technologies have a problem in that the assembly workability is greatly reduced because many components constituting the pillar formwork fixing device are poor in storage and have to be worked several times during the installation work.

In addition, the prior art has a problem that the labor cost of the worker is increased because two or more workers have to work together to bring the waste and increase the worker more than necessary.

The present invention has been made to solve the problems of the conventional column formwork fixing device, the screw fastener is formed on the inner surface of the square pipe-type fastening rod and the screw fastening groove is formed on the inner surface to be fastened to the screw fastener In order to fix the outer surface of the column formwork installed in the square shape by constructing the cross coupling sphere where the fastening rods cross each other, it is not only economical because it improves the work efficiency and the assembly efficiency. The purpose is to provide a column formwork for one-person workers who can easily work alone and induce cost reduction by manpower reduction.
