Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage ditch installation method for implementing a side ditch of a road or a drainage ditch of a building, and a grating support fitting for supporting and fixing a grating.

[0002]

2. Description of the Related Art In the conventional construction method, a steel material H such as a C type rope is
They should be placed back to back and sized appropriately, and the upper and lower parts should be temporarily fixed by welding with a rebar, etc., and then installed. After placing concrete, the upper rebar I
Remove the parts and finish the welding of the removed part with sander, and finish the water distribution in the groove inside J with mortar K, and then inside the groove J
After finishing the above, since the reinforcement welding was performed on the inside J of the groove with the rebar rod L such as a reinforcing bar, there were many work steps, and it took 2 times and 3 times. Also, in level adjustment, if you adjust the level with a camber (tapered wood piece) N etc. and adjust the left and right positions, the level will change again, so you have to adjust the two at the same time, which was a very difficult task.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to easily and easily construct a drainage groove and to reliably support and fix the grating, and a grating support method. It is to provide metal fittings.

[0004]

[Means for Solving the Problems] As a means for solving the problems, a concrete anchor is placed in the soil of a gas station or the like, and a base anchor having an anchor projecting on the lower surface of a plate having a connecting nut on the upper surface is planted. While embedding it in the concrete foundation, screw the lower end of the support bolt of the set bolt consisting of the set plate, the fixed nut and the support bolt into the connection nut, move each fixed nut up and down to adjust the level of the set plate, After tightening each fixing nut again, fix the set plate, fix the fixed part to the lower surface of the opposing support plate with the nut, insert the stopper into the insertion port and connect it, assemble the grating support bracket, and assemble the assembled grating After centering the support metal fittings on the set plate, fix them by welding, and then use a concrete casting curing iron around them. After raising, placed mortar in grating support fitting, the water gradient was formed by iron from above like, culvert installation construction method, which comprises placing a grating on the grating locking portion. In addition, the flat U-shaped insertion port provided inside the two support plates with the front U-shaped grating locking part formed by bending the flat plate and the front type that is detachably inserted into the insertion port A grating support fitting, characterized in that a connecting portion composed of a stopper is provided, and a flat plate-shaped fixing portion for fixing on a set plate is integrally fixed to a bottom surface with bolts and nuts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drainage ditch installation method of the present invention will be described below with reference to FIGS. (1) About 30 base anchors 2 in which concrete is placed in the soil 1 of a gas station or the like, and anchors 2C are projected on the lower surface of the plate 2b having the connecting nut 2a on the upper surface.
It is embedded in a concrete foundation while being planted at a pitch of 00 mm. (2) Support bolt 3C of set bolt 3 including set plate 3a, fixing nut 3b and support bolt 3C
The lower end of the set nut is screwed into the connecting nut 2a, the fixing nuts 3b are moved up and down to adjust the level of the set plate 3a, and the fixing nuts 3b are tightened again before the set plate 3
Fix a. (3), the fixing portion 4 is provided on the lower surface of the supporting plates 4a, 4a facing each other.
B is fixed with a nut 4c, and the stopper 4 is inserted into the insertion port 4d.
Assemble the grating support fitting 4 by inserting e and connecting. (4) After the assembled grating support fitting 4 is centered on the set plate 3a, it is fixed by welding. (5) After mortaring and mortaring the concrete with 0 concrete casting, the mortar M is put into the grating support fitting 4 and the water distribution M1 is formed from above with a trowel or the like. (6), the grating G on the grating locking portion 4a1
To place.

Next, the grating support fitting 4 will be described in detail with reference to FIGS. 3 and 4. Grating support bracket 4
Is a flat U-shaped insertion port 4d provided inside two support plates 4a having a front U-shaped grating locking portion 4a1 formed by bending a flat plate, and detachable from the insertion port 4d. A connecting portion 4f including a front stopper 4e to be inserted is provided, and a flat plate-shaped fixing portion 4b for fixing the set plate 3a on the bottom surface is integrally fixed by a bolt 4c1 and a nut 4c.

The width dimension 5 of the grating support fitting 4 may be set freely according to the size of the grating G. Further, the means for fixing the grating support fitting 4 on the set plate 3a is not limited to welding, but bolts or the like may be set arbitrarily.

[0008]

INDUSTRIAL APPLICABILITY The present invention has an effect that a drainage groove can be easily and easily installed without requiring skill, and that the grating can be surely and quickly supported and fixed.
