Description

[Detailed description of the invention] [Purpose of the invention] Industrial field of application The invention relates to a structural reinforcing bar for a bearing plate for integrally constructing a large plate made of reinforced concrete with an anchor bolt driven into the ground. It is.

BACKGROUND ART Conventionally, when constructing a bearing plate, anchor bolts 13 are drilled in a slope 11 cut from a ground 10 as shown in FIG. 7A by drilling a hole with a drill 12 as shown in FIG. 7B. Enter, then
As shown in FIG. 7C, a formwork 14 made of steel plate, wood, or plastic is attached to the exposed part of the anchor bolt 13, and a hardening agent 15 made of fluid such as concrete or mortar is cast, and after hardening, the mold is removed. As a result, a large plate 16 was formed as shown in FIG. 7D.

Problems that the invention aims to solve However, according to the above conventional construction method, large, heavy, and difficult-to-handle formwork such as steel plate is used, so it is difficult to carry it in, move it, and attach it to anchor bolts. Not only is it difficult and time-consuming, but
The concrete had to be removed from the mold after it had been poured and hardened, making the construction work complicated and prolonging the construction period.

In addition, conventional wooden formworks are difficult to reuse, and plastic formworks are expensive.

Furthermore, with conventional formwork, it is necessary to attach a soft material such as rubber to the bottom of the formwork to prevent the flowable hardening material from leaking, and to prevent gaps from forming between the ground and the formwork. There were also problems such as the unit cost of the formwork becoming high and the installation work becoming complicated.

The present invention was made in order to solve the above-mentioned conventional problems, and its purpose is to provide a structural reinforcing bar for a bearing plate that is lightweight, easy to handle, and inexpensive.

[Structure of the invention] Means for solving the problem The structural reinforcing bars for a bearing plate of the present invention are constructed by arranging reinforcing bars in a lattice shape, and the ends of some of the reinforcing bars are made almost at right angles. A large number of bent ends are formed around the plate reinforcing bars by bending, and thin reinforcing bars are arranged in a mesh or fence shape to form a band around the plate reinforcing bars. Assemble the mesh formwork, align the tips of the bent ends of the reinforcing bars for the plate with the lower ends of the mesh formwork, and tie these bent ends to the reinforcing bars of the mesh formwork with a binding material such as wire. The present invention is characterized in that the plate reinforcing bars and the mesh formwork are integrated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a structural reinforcing bar for a bearing plate, which is composed of a plate reinforcing bar 1a and a mesh formwork 1b.

As is clear from Figure 1A, the plate reinforcing bars 1a are constructed by arranging reinforcing bars in a lattice pattern, and the thickness of the reinforcing bars and the spacing of the lattice are determined depending on the ground, soil quality, and plate. Set as appropriate depending on the received pressure, etc. Further, the ends of some of the reinforcing bars of the plate reinforcing bar 1a are bent downward at approximately right angles, and a large number of bent ends 1 are formed around the plate reinforcing bar 1a.
form a′.

On the other hand, the net-like formwork 1b is constructed in the form of a band as a whole by assembling reinforcing bars thinner than the plate reinforcing bars 1a into a fine mesh or fence shape.

As shown in FIG. 1A, the structural reinforcing bars 1 for the bearing plate are constructed by constructing the mesh formwork 1b so as to surround the reinforcing bars 1a for the plate, and as shown in FIG. 1B. The bent ends 1a' of the reinforcing bars 1a for the plate are tied to the reinforcing bars of the mesh formwork 1b using a binding material such as wire 2 to integrate them.

Furthermore, if the length of the bent end 1a' of the plate reinforcement 1a is set to about half the height of the net formwork 1b,
As is clear from FIG. 1B, simply by aligning the tip of the bent end 1a' with the lower end of the mesh formwork 1b, the plate reinforcing bar 1a can be positioned approximately in the middle of the height of the mesh formwork 1b and integrated.

In this embodiment, the structural reinforcing bar 1 for the bearing plate is constructed in a square shape, but the present invention is not limited to this. For example, it may be constructed in a circular shape as shown in FIG. It may be any shape, such as a diamond shape or a diamond shape.

Further, a sleeve 1c (see FIG. 1) for inserting an anchor bolt may be attached to the center of the structural reinforcing bar 1 for the bearing plate, if necessary.

Next, a method for constructing a bearing plate using the structural reinforcing bar 1 for a bearing plate constructed as described above will be described.

First, as shown in Fig. 3, a hole is made with a drill 5 in a slope 4 cut into the ground 3, and an anchor bolt 6 is driven into the hole, and the structural reinforcing bar 1 for the bearing plate is fixed as shown in Fig. 4. .

Subsequently, as shown in FIG. 5, a fluid hardening material 7 such as concrete or mortar is sprayed. In this case, the fluid hardening material 7 is not only filled into the mesh formwork 1b, but also sprayed onto the outer surface of the mesh formwork 1b, as is clear from FIG. to bury.

Incidentally, as shown in FIG. 6, the flowable hardening material may be simultaneously sprayed over the entire surface of the slope other than the plate.

In addition, the topsoil on the mountain surface may be washed away due to rainfall,
If there is a risk that the topsoil will freeze and collapse during frozen ground, set the structural reinforcing bars 1 for the bearing plate on the slope on the same day after cutting the slope, and immediately fill and spray a fluid hardening material to form a large plate. At the same time, hardening material is sprayed on other slopes to prevent damage from rain and frost, and then an anchor plate is driven into the ground through the large plate to stably anchor the bearing plate. It is also possible.

[Effects of the invention] (1) The structural reinforcing bars for bearing plates of the invention are:
The ends of some of the reinforcing bars of the plate reinforcing bars, which are constructed by arranging reinforcing bars in a lattice pattern, are bent at almost right angles to form a large number of bent ends around the plate reinforcing bars. A net-like formwork is constructed by assembling thin reinforcing bars in a mesh or fence shape to surround the reinforcing bars for the plate, and the tip of the bent end of the reinforcing bar for the plate is attached to the mesh-like formwork. Aligned with the lower edge of the formwork, these bent ends were tied to the reinforcing bars of the mesh formwork with a binding material such as wire, and the reinforcing bars for the plate and the mesh formwork were integrated, making it extremely easy to use on site. It is possible to provide a structural reinforcing bar for a bearing plate that is not only easy and quick to assemble, but also strong, lightweight, and inexpensive.

(2) Since the bent ends of the plate reinforcing bars are fastened to the reinforcing bars of the mesh formwork using a fastening material such as wire, they can be fastened and integrated quickly and easily using inexpensive materials.

(3) By simply aligning the tip of the bent end of the plate reinforcing bar with the lower end of the mesh formwork, the position of the plate reinforcing bar relative to the height of the mesh formwork can be positioned reliably and accurately.

(4) The structural reinforcing bar for bearing plates of this invention is
In addition to temporary work such as retaining ground slopes, excavated surfaces of the ground, and foundation work excavation surfaces, it can be used for slope construction in emergencies such as disaster recovery, and for construction combined with vegetation construction methods. You can also do that.
