Abstract

(57) [Abstract] [Purpose] L-shaped slab 4 sharing the upper end surface with the sidewalk surface 2
When the vehicle rides on the curb A of, the force of arrow P is applied,
There is an engraved part in the lower part of the section A, and the structure is such that the concrete wall thickness is insufficient in terms of strength and the destruction is prevented. [Structure] A lid water receiving plane 10 for supporting one surface of the vessel lid 7,
In an L-shaped receiving frame made up of a wall surface 11 standing upright from one end of the horizontal surface, a ceiling surface 12 is planted further obliquely upward from the end surface of the wall surface 11, and a side wall 13 having a blind end surface in the longitudinal direction is provided. A configuration having.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a frame receiving tool for a sill lid which is installed at a boundary of a pedestrian road and constitutes a gutter for road surface drainage and which is incorporated in an L-shaped slab.

[0002]

[Prior art]

 Conventionally, an L-shaped frame block has a configuration in which an L-shaped receiving frame member 8 having an L-shaped cross-section is shared and two L-shaped receiving frame members 8 are provided in parallel.

[0003]

[Problems to be solved by the device]

 The main point of the present invention is that when the vehicle rides on the curb A of the L-shaped curb mass 4 that shares the upper end surface with the sidewalk surface 2, a force is applied to the arrow P, and the engraved portion is formed at the lower part of the section A. However, the technical problem to be solved is to construct a structure that prevents the destruction of concrete due to insufficient concrete thickness in terms of strength.

[0004]

[Technical means for solving the problem]

 The technical means for solving the above-mentioned problem is to construct a ceiling surface 12 in a substantially diagonally upward direction from an upper end of an upright wall surface 11 of an L-shaped receiving frame hardware 8 of an inverted L-shape having a conventional structure, In addition, the side wall 13 that makes the longitudinal end face of the receiving frame 9 blind is formed.

[0005]

[Action]

 With the above configuration, when the load P is applied to the curb A, the ceiling surface 12 of the receiving frame metal 9 made of cast iron or the like serves as a reinforcing material at the upper portion of the concrete engraved portion, and only the ceiling surface 12 is used as a piece. Although it is weak in holding and supporting, it has sufficient strength because it has a box shape due to the side wall 13.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, 1 is a roadway, 2 is a sidewalk, 3 is a concrete L-shape, 4 is an L-shaped slab, 5 is rainwater to an underground pipe, 6 is an opening, 7 is a lid , 8 is an L-shaped frame hardware, 9 is a sidewalk frame hardware, 10 is a lid water receiving plane, 11 is a wall surface, 12 is a ceiling surface, 13 is a side wall, and 14 is an anchor.

[0007]

[Effect of device]

 As described above, according to the present invention, the structure is simplified and sufficient strength is imparted, and there is an effect that it can be carried out by a conventional simple casting technique in manufacturing.

Claims (1)

[Scope of utility model registration request] 1. A receiving frame provided at a portion of a L-shaped slab that is installed at equal intervals of concrete L-shapes constituting road surface drainage gutters at the boundary of a pedestrian road to support a sill lid that closes an opening. A metal wall, especially on the sidewalk, has a wall surface that forms an L shape in an upright direction from a horizontal plane that supports the sash lid, and has a ceiling surface that is approximately obliquely upward from the upper end of the wall surface and that has a length that matches the concrete upright surface. An L-shaped frame lump receiving metal piece characterized in that it is provided with a side wall that is protruded and the end face in the longitudinal direction is blind.
