Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a separator used when constructing a footing portion of a cloth foundation.

[Conventional technology] Normally, a cloth foundation is constructed by laying cut stones at the bottom of the cut, and a cloth foundation with a footing is constructed by constructing the footing part and then creating an upright part to integrate it. It is something.

This footing is for reinforcing the foundation, and has become increasingly necessary as land prices have soared and the number of two- and three-story buildings has increased in recent years.

To construct this footing part 51, as shown in FIG. 7, piles 52 are driven into a place where split stones 6 are spread so as to have a certain width, and formwork plates 5 are arranged outside along the piles 52. . Then, after filling the outside of the form plate 5 with earth and sand 7 and fixing the form plate 5, concrete 8 is poured. The poured concrete 8 is densely filled and compacted by poking with a stick, etc., and the top surface is leveled with a trowel to finish. In addition, in order to securely fix the formwork board, it is also done to fix the formwork plate by nailing it to the formwork opening prevention crosspiece.

[Problems to be Solved by the Invention] However, the conventional method of constructing a formwork has the drawback that it requires considerable effort and time to construct the formwork, such as by piling and nailing. In other words, this is because it takes time and effort to continuously hold and fix the formwork boards at regular intervals, and especially when nailing the formwork boards using formwork stoppers, it is difficult to construct the formwork. Moreover, removing the formwork was also time consuming.

Furthermore, in the conventional method, it is difficult to arrange the formwork plates side by side with a constant width, so there is a drawback that the assembled width of the formwork plates is not constant and the width of the footing is not constant.

Furthermore, since it is difficult to stand the formwork plates vertically, misalignment may occur at the joints of the formwork plates.

[Means for Solving the Problems] Therefore, the present inventor has made the present invention as a result of intensive research in view of the above points, and its characteristics are as follows.
In a cloth foundation with a footing, it is used when constructing the footing part, and includes a rod-shaped main body, and is arranged at both ends of the main body and fits into the upper end of the form plate to sandwich the form plate. The upper limit position of the form plate is regulated so that a height difference is created between the fork-shaped support part and the upper end of the form plate provided on the support part and held between the main body and the support part. It consists of a locking part.

Here, the term "cloth foundation" as used herein refers to a foundation that is connected in a band shape and is constructed on the ground to support a building. Among these cloth foundations, those with a wide lower end and a so-called inverted T-shape are called cloth foundations with footings. A cloth foundation with a footing is formed by first constructing the footing portion and then constructing the rise of the cloth foundation on this.

The term "main body" refers to a rod-shaped object that has support portions at both ends that hold the formwork plate therebetween. The cross-sectional shape of this may be any shape such as round or square, or may be cylindrical like a pipe. Furthermore, since the width of the footing portion is determined by the length of the main body, it is preferable to configure the footing so that this length can be adjusted. Any adjustment method may be used, but various methods can be used, such as dividing the main body into two parts, providing one with a plate having a plurality of through holes, and providing the other with a member that can be inserted into the through holes. It would be convenient if it could be inserted and fixed in this position. Another possible method is to use one side of the main body as a pipe, insert the other side into it, and fix it with a screw provided on the pipe.

"Supporting parts" are provided at both ends of the main body and are formed into a fork shape. The formwork plate is fitted into and supported by this frame-like portion. Usually, it is simple and cost-friendly to form the support part with a bifurcated bar having a gap that allows the frame plate to be inserted thereinto. Furthermore, the closer the spacing is to the thickness of the formwork plates, the more closely the formwork can be arranged side by side.

[The locking portion J is meant to provide a difference in height between the main body and the upper end of the form plate when the form plate is inserted into the support portion. This is to prevent the formwork plate from entering the support portion beyond a certain level when the formwork plate is inserted. For example, this can be achieved by reducing the width of the support portion above a certain height, eliminating a space above a certain height, or providing a stopper at a certain height.

The purpose of this locking tool is to provide a space between the main body and the upper surface of the concrete, thereby making it possible to level the upper surface of the concrete with a trowel or the like.

[Example] FIG. 1 is a perspective view showing an example of the separator 1 of the present invention.

In this example, the main body 2 is rod-shaped, and the supporting parts 3 are composed of two left and right parts. Further, the locking portion 4 is configured to have a width such that a formwork plate does not fit into the upper portion of the support portion 3.

FIG. 2 is a perspective view showing the example in FIG. 1 in use.

The formwork plate 5 is fitted into the support part 3 of the separator 1 and assembled in parallel and upright position on the split stone 6. Concrete is poured into this space g1;

FIG. 3 is a sectional view of FIG. 2. It can be clearly seen that the formwork plate 5 is supported upright by the separator 1. In this way, concrete 8 is supported by separators 1 and poured into the assembled formwork. In this case, it is preferable to fill the outside of the formwork plate 5 with earth and sand 7 to support the formwork when the formwork plate 5 is assembled, and then concrete 8 is poured. The concrete 8 is filled up to the chain line area shown in the figure, and compacted densely by poking with a stick or the like. Then, the top surface of the concrete 8 is leveled and finished with a trowel or the like. This troweling operation can be easily performed because there is a height difference between the main body 2 of the separator 1 and the upper surface of the concrete 8.

Then, when the concrete 8 has solidified to some extent, the separator 1 is removed and the construction of the footing portion is completed.

FIG. 4 (al (bl) shows another embodiment of the present invention, in which the length of the main body 2 is adjustable.

In this case, the main body 2 is divided into two parts, a hook 9 is provided on one side, and a plurality of hooks 10 are provided on the other side. In this example, the length of the main body 2 is adjusted by hooking the hook 9 to any one of the four hooking parts 10. In addition, as shown in FIG.
It is also possible to divide it into two parts, each with a screw thread (one with a reverse thread), and to adjust it steplessly with the turn buckle 11.

FIG. 6 (al) and (bl) respectively show other embodiments of the locking part 4. In FIG. The projection 12 is brought into contact with the protrusion 12. In addition, as shown in FIG. 3B, a screw thread is carved into the outer support part 3, and the position can be adjusted by screwing a nut 13 into the thread. This is how it was done.

C Effects of the Invention As described above, the separator according to the present invention has various excellent effects described below.

■ It has a simple structure and can be reused, so it costs almost nothing.

■ The assembly width of the formwork plate is always constant, and the formwork plate can be supported vertically.

■ In particular, if the joints of opposing formwork plates are shifted and assembled, the formwork can be assembled straight without meandering.

■ By using this separator, even unskilled workers can easily and reliably assemble the formwork, saving labor costs and working time.
