Definitions
- the present invention relates to an improvement of a buried object such as a recessed lighting device buried in a concrete pavement such as an airport runway, a taxiway, an apron, or a road, and particularly to a buried in a prestressed concrete pavement.
- the present invention relates to a recessed lamp and a buried object.
- the recessed lighting device 30 is, for example, buried in an airport runway or the like, and has a bottomed cylinder buried in a prestressed concrete pavement plate (hereinafter referred to as “PC pavement plate”) 31. It is generally composed of a base 32 in the shape of a circle, and a lamp 34 attached to the upper part of the base 32 via a lamp holding member 33 called an adjustment ring.
- the recessed lighting device 30 can be easily embedded in the PC pavement plate 31 by placing concrete at a predetermined position on the existing pavement surface together with a buried pipe, PC steel, etc., and then casting concrete. be able to.
- the outer surface of the base 32 of the recessed lamp 30 is a flat cylindrical body, the connection between the outer surface of the base 32 and the PC paving plate 31 is inherently required.
- the strength (combination) is not enough.
- a large load from an aircraft or the like is applied to the upper surface of the lamp body 34, the resistance between the cylindrical outer peripheral surface of the base 32 and the PC paving plate 31 is small, and the load is reduced to the base 3 2 Take intensively below.
- a load exceeding the strength of the PC paving plate 31 below the base 32 is applied from the bottom of the base 32, causing damage to the concrete part below the base and the resulting light fixture. Collapse is likely to occur.
- the PC pavement plate 31 below the base 32 is directly attached to the lower surface of the base 32.
- a downward stress acts from the edge of the lower end of the base 32. Therefore, when a large load such as an aircraft repeatedly acts on the recessed lighting device 30, the portion supporting the base 32 of the PC pavement plate 31 becomes cracked in a short period of time and becomes weak, The recessed lamp 30 may collapse.
- the first problem to be solved by the present invention is to effectively use the prestress added to the PC paving plate 31 to press the outer peripheral surface of the base 32, thereby causing a gap between the PC paving plate 31.
- the structure has a structure that can prevent the load from concentrating below the base of the recessed lamp.
- An object of the present invention is to provide a recessed lamp.
- arrow S As shown in, the prestress from the PC pavement plate 3 1 acts to press the outer peripheral surface of the base 3 2, but the outer surface of the base 3 2 having greater rigidity than the PC pavement plate 3 1
- the applied prestress is attenuated by the tension on the outer peripheral surface of the base (constraining force counteracting force in the opposite direction). For this reason, the bonding force between the PC paving slab and the PC paving slab is reduced, and the holding power of the base by the PC paving slab is reduced.
- the tension of the base 32 has a component for canceling the prestress of the PC pavement plate 31, the lower portion of the base 32, that is, the portion supporting the load applied to the base 32. In this case, the prestressing of the PC pavement plate 31 is insufficient.
- the PC pavement plate 31 maintains the strength of the concrete by applying a certain pre-stress in advance, so the strength is reduced if the pre-stress is insufficient.
- the outer peripheral surface of the base 32 which is a cylindrical body with a bottom, is made of a metal plate 32a and is deformed to some extent in the thickness direction with respect to the stress from the direction crossing the plate surface, so that the stress force The amount of elimination is small compared to the lower edge of the base.
- the lower end edge of the base corresponds to the outer peripheral edge of the bottom plate 32b, so that it is hardest to deform and has the highest rigidity. It has a strong power to overcome, and reduces the prestress from PC paved version.
- the lower end edge of the base 32 makes the PC fining plate located below the base bottom. The applied prestress is reduced, and the concrete strength in that area is reduced. In this state, if a large load from an aircraft or the like is applied to the upper surface of the lamp, bending stress will cause cracks in the PC paving slab located below the base, and eventually the embedded lamp 30 Inconveniences such as collapse are likely to occur.
- the second problem to be solved by the present invention is to minimize the area in which the base constituting the embedded lamp buried in the PC paving slab reduces the prestress by restraining the prestress on the outer peripheral surface. As a result, the prestress is applied more effectively to the entire base, thereby increasing the bonding force between the base and the PC paving slab more effectively, and reducing the strength of the concrete portion located below the base. It is an object of the present invention to provide a recessed type lighting device for preventing the occurrence of a lighting problem. Disclosure of the invention
