Description

Reinforcing device of forms for constructing buidings and a support Technical Field

The present invention relates to a structure for reinforcing a formwork for a building constructed with cement mortar, that is, a cement mortar filled with a filling and used essentially for curing the cement mortar, and a support thereof.

Formwork is used in the construction of building structures that are constructed by curing cement mortar. Such formwork is a construction member which is essential for curing cement mortar. It is manufactured by installing a rim steel for reinforcement by turning to a rectangular plywood edge cut to a suitable width, ie, subunit area, in consideration of transportation and storage. . Thus, formwork is formed by connecting at least one unit board made of small units according to the shape and area of the structure. Here, the side strength of the formwork is weak when the formwork is formed by connecting several unit plate materials formed by small unit areas. In other words, the formwork formed by connecting the unit plate materials made of thin plates is pushed out by heavy cement mortar load. A reinforcing structure is additionally installed to support each unit board from the outside of the formwork.

Such a reinforcing structure is usually a reinforcing bar using lumber or section steels having a suitable length, and in recent years, many sections are mainly used. As an example, the reinforcing bar formed by arranging at least one or more section steels in parallel is installed at a suitable distance on the outward side of the formwork, and the reinforcing bar is formed by using a fastening nut on the fastening bar that is directed outwardly from the inside of the formwork. Integral with and to achieve the desired reinforcement structure.

However, these reinforcing rods had to be cut to a certain length of a separate section steel, and thus a joining process using welding or binding bolts for joining with adjacent section steels was not easy to manufacture and the manufacturing cost was increased. Installation and dismantling work is inconvenient, that is, the work to loosen and tighten the fastening nut on the fastening rod is not easy to install and dismantle the formwork, the construction of the building construction is poor.

The present invention has been made in consideration of the above circumstances, and its purpose is to use the ready-made steel as it is as a reinforcing bar and to easily install the reinforcing bar by using a support that is simply fitted to the unit panel of the formwork. It is to provide a formwork reinforcement device for building a building easy and therefore excellent construction.

Another object of the present invention is to provide a support for formwork reinforcement for building a structure to improve the installation and dismantling work of the reinforcement by simply installing the reinforcement using a support that is simply fitted to the unit panel of the formwork. Is in.

The object of the present invention is achieved by providing a reinforcement device and a support for formwork for building structures that are constructed with cement mortar, that is, cement mortar is filled with filling and used essentially for curing the cement mortar. This reinforcement device has horizontal support in the horizontal direction at the top, and is formed for cement mortar curing by connecting the unit boards with the frame steel to the edge of rectangular plate cut in small units according to the shape and area of the building structure to be constructed. A reinforcing device for supporting the side of the several reinforcing bars, the reinforcing bar is to use a ready-made form steel; And one end is fitted to the frame-shaped steel of the unit plate by using a wedge, and the other end includes the support being installed several times by allowing the reinforcing rod to be fitted longitudinally to be bound by a binding bolt to maintain proper spacing on the formwork. It is a reinforcement device of formwork for building buildings characterized by.

Next will be described in detail with respect to an embodiment of the present invention. Figure 1 shows the formwork installed by using the reinforcement of the formwork for building buildings according to the present invention. Formwork 10 is usually made by connecting the unit panel 12 of the tank to be manufactured in small units according to the shape, area of the designed building structure. The formwork 10 installed in this way is supported on the side by the horizontal support 13 is installed in the horizontal direction at the upper end and the reinforcing rods 14 installed in the transverse or longitudinal direction on the entire surface of the formwork 10. In this case, the unit panel 12 has a rim steel (16) to the edge of the plywood cut to a predetermined width in consideration of transportation and storage, the rim steel (16) of the additional unit is coupled to the adjacent unit panel Equipped with a coupling hole or insertion groove (16a) for binding.

The present invention relates to a reinforcing structure that supports the side of the formwork 10, and more specifically, it is installed using the support 20 shown in FIG. The support 20 is a tubular receiving portion 22 into which the reinforcing rod 14 provided with a ready-made shaped steel that is cut and supplied to a predetermined length without additional processing is inserted in a longitudinal direction, and the receiving portion 22 is one side. And a support piece 24 extending a predetermined length of the support piece 24, and a binding member 26 of a screw bolt that is penetrated into and out of the accommodation portion 22 and installed on the other side of the accommodation portion 22. have.

3 and 4 are shown cut along the line A-A or B-B of Figure 1, it is shown in detail with respect to the configuration of the subject innovation reinforcement device. First, at least one supporter 20 is fitted to the reinforcing rod 14 by using the receiving portion 22 to maintain a proper distance. In this way, the reinforcing bar 14 having the at least one support 20 installed thereon is installed to extend over the entire length of the formwork 10. At this time, the upper end of the reinforcing rod 14 is to provide a supporting force to the horizontal support neck 13 is installed on the upper end of the formwork (10). The support piece 24 of the support 20 is inserted into the insertion groove 16a formed when the frame-shaped steel 16 installed at the edge of the unit panel 12 of the formwork 10 is joined to the adjacent side. The first wedge which fits and engages and penetrates the through-holes 16b of the rim steel 16 in the horizontal direction intersecting the support piece 24 in the through-hole 24a formed at the end side of the support piece 24. (17) and the second wedge (18) is installed in the vertical direction again to the first wedge (17) to form a reinforcing device.

In addition, the support 20 is installed on the upper side of the reinforcing table 14 is further provided with a supporting member 23 for supporting the lower portion of the horizontal support neck 13 of the upper end of the formwork 20.

Figure 5 (a, b) shows another embodiment of the present invention support. What is different in the present embodiment is that the shape of the accommodating portion 22 is square or semicircular to match the shape of the reinforcing table 14 to be supported. It may have other shapes.

And (c) as another embodiment of the present invention the support of the present invention, in the present embodiment by dividing the main wall of the receiving portion 22 of the support 20 to the left and right to open and close one side. This configuration is for convenience in installation or dismantling of the reinforcement 14.

Explaining the effect of the formwork reinforcement device and its support for building the present invention, the present invention can use the ready-made steel or the stock steel of the stock as it is without a separate processing process, thereby reducing the material cost and thus, the construction cost There is an advantage to reduce.

The present invention is also easy to install and dismantle the reinforcement device has the effect of improving the workability.

As described above, an embodiment of the present invention has been described, but the present invention is not limited thereto and may be changed within the scope of the claims.
