Description

[Detailed explanation of the idea] This idea relates to stairs.

For stairs with support plates that support the treads from below fixed to the inner surfaces of the stringers that face each other on the left and right, if the dimensions of the treads and the support plates in the horizontal plane length direction are not the same, there will be a gap between the treads and the stringers, or Either the tread was bent or the support plate was not securely fixed.

This idea was made to solve the above problem, and even if there is a difference in the horizontal dimension of the tread and support plate, there will be no gap between the tread and the stringer, and the tread will not bend. Also, the fixation of the support plate provides a reliable staircase.

An embodiment of this invention will be described below based on the drawings.

In FIG. 1, reference numeral 1 indicates a side beam, and this side beam 1 is provided to face each other on the left and right sides.

Reference numeral 2 denotes a downwardly U-shaped support plate, and the support plate 2 is attached by bolting the side plate 3 to the side beam 1 as shown in FIG.

An elastic spacer 4 is sandwiched between the side plate 3 and the inner surface of the side beam 1, and the thickness of the spacer 4 is changed by the adjusting pressure of the bolt.

Note that as the spacer 4, a rubber plate, a soft synthetic resin plate, or the like is used.

Reference numeral 5 denotes an L-shaped cedar board, and this L-shaped board 5 is cut out from a tread 6 and a riser 7 formed by hanging down from the front end of the tread 6, and when the tread 6 is placed on the support plate 2, both of them are connected to the side girder 1. The stringer 1 is fixed using nails, screws, etc.

As described above, the present invention provides an arrangement in which a resilient spacer 4 is inserted between the inner surface of the stringer 1.1 facing left and right and the side plate 3 of the downward U-shaped support plate 2, and the spacer 4 is inserted between the stringer 1 and the support plate. The side plate 3 of 2 is fixed with bolts, and the tread plate 6 of the L-shaped plate 5 formed by hanging the riser plate 7 from the front end of the tread plate 6 is placed on this support plate 2. is fixed to the stringer 1, and the dimensions between the stringers 1 and 1 are increased or decreased by changing the thickness of the spacer 4 by adjusting the adjustment pressure of the bolts applied to the spacer 4. 6 is stringer 1,
1, and the step board 6 comes into contact with the inner surface of the side beams 1, 1.

Therefore, there is no gap between the tread and the stringer, which is a problem posed by the present invention, the tread does not bend, and the support plate is securely fixed.

Claims (1)

[Scope of utility model registration request] An elastic spacer 4 is inserted between the inner surfaces of the side beams 1, 1 facing each other on the left and right and the side plate 3 of the U-shaped support plate 2 facing downward, and the side plate 3 of the side beam 1 and support plate 2 are fixed with bolts. Then, when the tread plate 6 of the L-shaped plate 5 formed by hanging the riser plate 7 from the front end of the tread plate 6 is placed on this support plate 2, the L-shaped plate 5 is further fixed to the stringer 1. A staircase.
