BG1252U1 - A protective grid for a draining channel - Google Patents

Abstract

The protective grid for a draining channel can be applied in the road building and, more specifically, for diverting the rainwater to the edge of the pavement. It is made impossible to separate the protecting grid from the frame of the draining channel and to be opened when being stepped upon by vehicles, at the same time its durability being increased. The protective grid includes a frame (1) inwhich the grid (6) is fastened and they are joined by means of at least one stud hinge (9) fixed in one end of the frame (1) and grid (6) and crossing completely through the frame (1) and partially through the grid (6).

Description

The drainage drainage grille is used in road construction, and especially in the discharge of rainwater at the end of the roadway.

BACKGROUND OF THE INVENTION

Protective grilles are known for a drainage duct made of cast iron or reinforced concrete castings, representing a frame with a protective grille in which elongated openings are formed.

The disadvantages of the known drainage grilles are that they are fully open and the safety grille is completely detached from the frame. This is the reason why much of the safety grilles are stolen and canals become very dangerous for pedestrians and vehicles. Another disadvantage is that the known safety grilles open when they come into one end of the vehicles, which is dangerous for pedestrians and vehicles. Another disadvantage is that the reinforced concrete castings from which the protective grilles are made have low durability and durability. The atmospheric conditions and the loads to which they are subjected, lead to their destruction, creating openings dangerous for pedestrians and vehicles.

The technical nature of the utility model

The task of the utility model is to create a drainage grille, which prevents the grille from being detached from the drainage channel frame and not open when approaching vehicles, while having increased durability and increased durability.

The problem is solved by a drainage grille including a frame in which the grille is mounted. According to a useful model, the frame and the grille are connected by at least one pin hinge mounted at one end of the frame and the grille and extending completely through the frame and partially through the grate.

The advantages of the drainage grille are that it is not possible to detach the drainage grille from the drainage frame and to open upon approaching vehicles, while increasing durability and increased durability.

The drainage grille includes a frame 1 which has a rectangular shape and consists of a front 2, a rear 3 and two lateral sides 4. The front 2 and the rear 3 sides are in the horizontal direction of the letter "b", and both side 4 has the form of an upside down "T". In the upper rear part of the two lateral sides 4 of the frame 1, openings 5 are formed along the entire thickness of the lateral sides 4. To the frame 1 is attached a grate 6, which is a monolithic plate in which longitudinal openings 7 are arranged parallel to the front and the back of the grate 6. Two blind holes 8 are formed at the rear of the sides of the grille 6, the axes of which coincide with the axes of the holes 5 of the frame 1. These

1252 υι two blind openings may be completely drilled such that the two openings 8, the axes of which coincide with the axes of the openings 5 of the frame 1. In the assembled position of the frame 1 with the grate 6 in the openings 5 and in the blind or openings 8 is located at least one hinge pin 9.

Using the utility model

Frame 1 is placed at the top of the constructed drainage channel (not shown in the accompanying drawings). Installation shall be carried out before the last layer of road surface is installed or installed in the existing road surface, taking into account the level of the frame 1 not to exceed the level of the floor. The frame 1 serves to hold and restrict the protective grille from being displaced to the sides and from falling deep. At least one hinge 9 is mounted on the frame 1, which enables the safety grille to open and does not allow it to be detached from the frame. The guard 6 is placed at the top of the drainage channel on the frame 1. It is a cast iron guard with longitudinal openings that enters the frame so that it closely overlaps with the level of the frame and the roadway. Thanks to the hinge pin 9 mounted at one end of the guard 6, it becomes openable, but at the same time it is not disassembled. When assembling the roadway article, it is assembled and its individual elements cannot be separated.

Claims (1)

1. A drainage grille comprising a grille which is mounted in a frame, characterized in that the frame (1) and the grate (6) are connected by at least one pin hinge (9) mounted at one end of the frame (1) and the grate (6) and passing completely through the frame (1) and partly through the grate (6).
