Fixing bar for connecting slab concrete form to wall concrete form}

The present invention relates to a connector for connecting a wall formwork and a slab formwork, and more particularly, a pedestal stacked on the top surface of the wall formwork, and one or more control units and control units stacked on the pedestal and低位) The wall formwork and the slab formwork connector which can be easily connected between the wall formwork and the slab formwork, and the height can be adjusted according to the height of the wall to be constructed by being composed of the joints joined together in a state where the slab formwork is stacked on the upper surface. will be.

Concrete buildings start with the installation of formwork for the construction of walls and slabs. The walls and slabs are made by creating a frame with the same space as the shape of the walls and slabs, and injecting and curing concrete into the interior of the frame. As described above, a mold having a space for injecting concrete as described above is a formwork, and the formwork is installed by connecting a plurality of formwork panels on the same plane.

The formwork as described above, the wall formwork formed in the wall-shaped interior space is installed upright on the floor, and the slab formwork is installed in the horizontal direction on the top surface of the wall formwork, as follows. .

As shown in FIG. 1, the conventional formwork is a wall formwork 11 installed to face each other by standing upright on an upper surface of a wood foundation bar 12 fixed to the bottom A, and an upper end of each wall formwork 11. It consists of a slab formwork 13 and the like installed horizontally in a state where one end is stacked on the surface.

By the way, the slab formwork 13 has been commonly used wood plywood bar, in order to support the concrete to be poured a plurality of joists (14, 長線) in close contact with the bottom of the slab formwork 13 in parallel, On the bottom of these joists 14, a plurality of yokes 15 are orthogonal to and parallel to them, and a plurality of supports S3 are erected up to the floor A along the bottom of each yoke 15 to form a slab formwork. 13) as a structure for supporting the slab formwork 13 and the wall formwork 11 are coupled to the wood (T) parallel to the joist 14 along the upper end of the wall formwork.

In addition, on each rear surface of the wall formwork 11, a plurality of formwork panels constituting the wall formwork are prevented from being separated from the initial assembly position by the pressure of the load of the concrete poured for the construction of the wall W. The vertical support (S1) and the horizontal support (S2) is coupled, the slab formwork 13 made of plywood is a structure that is fixed to the nail (T) fixedly coupled along the upper end of the wall formwork (11).

In the case of the above formwork, the wall formwork is made of wooden formwork panel made of wood frame and plywood, and the slab formwork lacks rigidity because plywood is used, and the installation time is long because excessive reinforcing members are used to reinforce it. Not only that, but when the formwork is dismantled, there is a disadvantage that the damage rate of the formwork panel, plywood, reinforcing member, etc. is high.

Therefore, in recent years, a metal formwork panel made of a metal such as steel or aluminum alloy frame has been developed and used for wall formwork as well as slab formwork.

However, because the metal formwork panel, such as the wall formwork is used for the slab formwork, the connection structure between the wall formwork and the slab formwork is also different compared to when the plywood is used for the slab formwork.

As shown in FIG. 2, the formwork in which the metal formwork panel is used is connected to the top surface of the wall formwork 21 and has a bar-shaped connector 23 having a relatively long length compared to the cross-sectional dimension, and the connector ( 23, the horizontal slab formwork 22 is in close contact with the upper side of the side, the wall formwork 21 and the connector 23 and the connector 23 and the slab formwork 22 are in close contact with each other to the connecting pin (P). It is a structure that is coupled through.

By the way, the connector 23, in the cross-sectional view, one side of the lower end is open state, the support ribs L1 and the lower end of the coupling ribs (L2) of the side end in the state of being broken with the teeth (L1) for each formwork and pin connection A plurality of circular connection holes (h) are formed through the longitudinal direction, respectively, there is a problem when installing the formwork.

The ribs L1 and L2 and the connection holes penetrated in the frame of the formwork panels 21A and 22A constituting each formwork are formed at regular intervals so as to match each other, but the connection of the ribs according to the construction site conditions. The connection hole of the ball and the formwork panel may not be exactly matched with each other. In this case, since the two connection holes must be matched, the formwork becomes difficult and the installation time becomes long.

In addition, since the outer end of the support rib L1 and the lower end of the coupling rib L2 are separated from each other, the ribs L1 and L2 may be deformed by external loads or impacts during the installation, dismantling, and handling of the formwork. When the slab formwork is not sufficiently supported in the state in which the slab formwork is connected to the joining rib L2, the joining rib L2 may be easily deformed downward.

And while the formwork panel constituting the formwork is standardized and manufactured in a constant length, the height from the floor to the bottom of the slab or the thickness of the slab may vary depending on the building, and accordingly the distance between the floor and the slab is appropriate. Since all the connectors having a height must be provided, the manufacturing and inventory costs of the connector are increased.

The present invention has been made to solve all the problems of the conventional connector used for connecting the wall formwork and the slab formwork when installing the wall formwork and the slab formwork using the formwork panel, one end of the horizontal slab formwork is laminated It is not only stable in connection, but also easy and simple to connect with the connection hole of formwork regardless of the horizontal position of formwork panel. It is an object of the present invention to provide.

Another object of the present invention is to provide a formwork connector that can reduce the inventory cost for retaining the connector for each height of the slab by having a multi-stage stacking structure capable of height adjustment according to the height of the slab.

Another object of the present invention is to provide a connector that is easy to stack operation despite having a laminated structure, and can maintain a stable state without flowing in the width direction in a stacked state.

The above object of the present invention is achieved by a multi-stage separable stack structure consisting of a pedestal and one or more control rods and connecting rods sequentially stacked, and a straight connection hole respectively formed along the longitudinal direction of the pedestal and connecting rod.

Wall formwork and slab formwork connector of the present invention, because the height can be adjusted, can reduce the inventory cost for the connector having to retain the connector according to the height of the slab, and the number of holes in the form of connecting the pin and the coupling joints Is not formed at regular intervals independently formed by a long straight line has the advantage that can be easily coupled to the formwork while moving the connecting pin along the connecting hole regardless of the horizontal position of the formwork.

In addition, since the slab formwork is combined in a stacked manner, the deformation resistance of the connector is significantly increased, and thus the breakage rate during the installation, dismantling and handling of the formwork is significantly reduced.

In addition, the coupling protrusions and the coupling grooves provided in the pedestal, the adjustment bar and the connector have a structure in which the cross-sectional area is gradually enlarged from the upper end to the lower end on the longitudinal section, thereby making it easy to insert the coupling protrusion into the coupling groove, There is an advantage that the insertion state of the groove is always maintained in a constant form.
