Description

Technical Field

[0001] The present invention relates to a gutter cover that protects damaged gutters of buildings and the like and can be used in the same way as new ones.

Background Art

[0002] As a conventional technique, a flat plate is bent to form a top plate on the upper surface, a horizontal grating locking portion is formed below it, and a holding portion connected vertically is provided on the grating locking portion. A pedestal is provided at the lower part of two support plates, and a detachable width holding plate is provided between the grating locking portions of the two support plates. A grating support tool characterized by this, and when placing disposable concrete, the upper end of the lower plate of the base anchor is visible and constructed at a required interval. A first step of preliminarily attaching an upper plate with a long hole for placing the grating support tool drilled between the anchor bolts of the base anchor and temporarily fixing it with nuts; a second step of fixing the grating support tool on the upper plate and performing vertical adjustment with each nut to level the concrete finish; a third step of performing horizontal adjustment with each nut to adjust the horizontal level of the grating support tool; a fourth step of reinforcing the area around the base anchor with steel bars, placing paving concrete, and finishing along the top plate; a fifth step of removing the width holding plate and constructing a water gradient on the inner bottom surface of the grating support tool; and a sixth step of arranging and fixing a bolt-fixed grating between the grating locking portions. There is a drainage gutter installation method characterized by consisting of these steps. (See Patent Document 1)

[0003] Also, as another conventional technique, a connecting portion including an insertion port and a stopper detachably inserted into the insertion port is provided inside two support plates formed by bending a flat plate to form a top plate on the upper surface and a grating locking portion below the top plate, and a locking piece is formed on the bottom surface. In the grating support fitting, the grating support fitting is characterized in that an air vent hole is provided in the top plate. When placing the disposable concrete, the top edge of the lower plate of the base anchor is constructed at a required interval so as to be visible, and an upper plate on which the grating support fitting is placed is pre-attached between the anchor bolts of the base anchor and temporarily fixed with nuts in the first step. In the second step, the grating support fitting is placed on the upper plate, and each nut is adjusted to level the concrete finish. In the third step, the horizontal level of the grating support fitting is adjusted, and in order to fix the support plate, a clamping portion of the clamping plate of the mounting fitting is attached to the upper plate, a hook shaft is attached to the support portion, the tip of the hook is locked to the locking piece of the support plate, and the clamping portion is fixed with bolts and nuts, and the tip of the hook is locked and fixed to the locking piece with nuts. In the fourth step, reinforcing bars are arranged around the base anchor, paving concrete is placed, and paving concrete can be surely placed around the support plate, and the grating is placed in the grating locking portion of the support plate. There is a drainage ditch installation method characterized by construction by the fourth step. (See Patent Document 2)

Summary of the Invention

Problems to be Solved by the Invention

[0005] The above two conventional techniques are inventions of the present applicant and are used when newly constructing a drainage ditch. They are still well-received and have obtained market evaluations. This application is a groove cover that can be used in the same way as a new one by removing the grating for gratings and supports that have been deformed or damaged due to long-term use.

[0006] The present invention aims to solve the problems existing in such conventional configurations. Mainly, the drainage grooves of existing gratings may be damaged after long-term use and may be left as they are. The purpose is to provide a groove cover that can remove the grating, protect the upper part, and be used safely.

Means for Solving the Problems

[0007] In order to achieve the above object, the present invention forms a groove portion provided with a substantially U-shaped drainage port at the center of a cover body of a long flat plate, and forms a fixing portion provided with mounting holes in both horizontal directions. Also, The depth and width of the groove portion are characterized by being smaller than the height and width of the grating.

Effects of the Invention

[0008] 1), This groove cover can be easily and surely attached with bolts from above in a state where the grating of the existing damaged grating drainage groove is removed by the groove portion and the fixing portion, and it is possible to walk or run safely on the groove. 2), By making the depth and width dimensions of the groove portion smaller than those of the grating, it can surely enter inside and drain water.

Modes for Carrying Out the Invention

[0010] 1 is a trench cover, which forms a groove part 2a with a plurality of rectangular drainage ports 2a1--- in a substantially U-shape in the central longitudinal direction of a cover body 2 of a long flat plate, and forms a fixing part 2b with a plurality of long hole-shaped mounting holes 2b1--- in both horizontal directions on both sides. Note that the depth F and width H of the groove part 2a are made smaller than the height and width of the grating.

[0011] A construction example of the trench cover 1 will be described. For example, after removing a grating (not shown) of a grating support GS embedded in concrete K that has been deformed or damaged after long-term use, the groove part 2a of the trench cover 1 is inserted from above, and an anchor bolt B is screwed into the mounting holes 2b--- of the fixing parts 2b·2b and fixed to the concrete K, and drainage HS can be discharged from the drainage port 2a1.

[0012] In the above embodiment, the material is not particularly limited, and iron, stainless steel, etc. are conceivable. Also, the size, length, etc. of the trench cover may be determined according to the need. Furthermore, the size, number of drainage ports, number of mounting holes, etc. may also be determined according to the need. Furthermore, it can also be used for C-shaped grooves and the like of conventional construction methods.
