Description

Clamp Assembly for Fixing Concrete Form work and Pipe

The present invention relates to a clamp assembly for fixing a concrete formwork and a single pipe pipe, and more particularly, to a clamp assembly for combining a single pipe pipe for fixing and supporting a form horizontally and vertically when assembling a concrete formwork and a formwork.

In general, a formwork is a temporary structure in which unhardened concrete is poured in order to make a concrete structure into a certain shape or size, and cured and supported until the desired strength is reached, and is also called a formwork. Along with concrete and reinforcing bars, it is a very important element in civil engineering and construction work, and it is also used as a term to refer to the dongbari supporting temporary materials. The formwork is designed and constructed to fit the shape or dimensions of the finished structure in order to obtain the desired shape.

Formwork is usually made up of a cladding in contact with unconsolidated concrete and a brace, wale, and form tie that supports it. Steel wires, bolts, and form ties that penetrate the concrete are also used. In many cases, it is easy to remove after hardening by applying a release agent to the blocking board beforehand. It will support the load of concrete together with the caster, and it must be made strong so that the concrete does not crack due to deformation of the form due to the pressure or vibration of the concrete poured into the form, or impact during concrete pouring.

If the form is deformed due to lack of hardware such as fasteners, unequal settlement due to poor copper rods, or form deformation due to lateral pressure of concrete, the deformation due to external force is greater than the plastic deformation capacity of concrete, which may cause cracks. Moreover, when pouring concrete, severe vibration or high pressure may be applied to the formwork, or thermal stress may be generated due to steam curing. Since it is used repeatedly, the formwork should be strong and easy to assemble and remove.

Depending on the type of formwork, wood formwork, euroform, large panel method, table form, iron removal form, gang form, tunnel form, active form, automatic rise form, al form, warp form, concrete structure integral external insulation form, steel wire reinforcement plastic are used. A variety of complex forms are being developed, such as a form using Except for a small area, curves, or curves among the formwork, standardized formwork is used for most walls.

As for the installation of Euroform, which is mainly used among the formwork, the work of assembling the formwork begins when the reinforcing work of walls and columns is completed to some extent. If the floor surface is horizontal, it is okay to combine the foam in the bare floor construction, but if there is a deviation or it is difficult to combine it with only concrete nails, a mudsill is installed. Lay out a square with wood to be level with the designated ink line and assemble Euroform on it. Euroform also has separate nail holes for bonding with wood. To make it easier to remove the nail head when dismantling it, leave about 1/3 to 1/4 of the nail head and bend the nail head. Common Euroform has holes of a certain size for each interval, and a wedge pin for coupling is inserted between them and assembled. Since the weight and pressure of the concrete cast object is very high, to prevent the form from collapsing or bursting under this pressure, a single pipe pipe (or wale, bracing, bundle, bracing) and form ties, etc. are installed.

Conventionally, a wedge pin is inserted and fixed in an assembly hole formed on the side of the Euroform to be interviewed while installing the Euroform vertically and horizontally for pouring a concrete wall. In addition, a horizontal single pipe pipe and a vertical single pipe pipe or braces are installed on the rear surface of the installed Euroform to support the weight of the concrete injected into the Euroform. At this time, a plurality of wedge pins are used to couple the Euroform continuously installed vertically and horizontally, and a plurality of hooks fixed to the Euroform are used to couple the horizontal single pipe pipe and the vertical single pipe pipe to the Euroform, and the single pipe pipe Use pipe clamps to join them. Therefore, there is a problem in that the construction period and construction cost increase due to the disadvantage that the number of work hours is increased and the number of working people and time are increased because many auxiliary materials are applied for the installation of Euroform in the prior art.

As a prior art related to the present invention, Patent Document 1 discloses a first body 12 in which a pipe is drawn in, a hemispherical inner surface is formed, and a first fitting hole 11 is formed in the inner surface, and the first body ( A second body 14 having a hemispherical inner surface that is hinged by one side of 12) and a hinge pin 13 and a pipe is drawn into the inner side, and the first body 12 and the second body 14 a clamp (10) having a bolt (15) provided on the upper side of the first body (12) for fastening and a nut (16) fastened to the bolt (15); The bonding surface 22 and the bonding surface having a second fitting hole 21 coming to a position corresponding to the first fitting hole 11 through the inner surface of the first body 12 of the clamp 10 is through a bracket 20 having a fastening surface 24 bent from 22 and having a fastening hole 23 formed therein; The first body 12 of the clamp 10 is connected to the first fitting hole 11 and the second fitting hole 21 of the bracket 20, and fixed flanges 31 and 31 are formed at both ends, respectively. A construction scaffolding clamp coupling structure including a fastening member 30 is disclosed.
