JP3165580U - L-shaped reinforcing plate for stairs for built houses - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a stomping sound of a staircase for a wooden house. SOLUTION: This is a reinforcing plate for a staircase for a wooden house, which comprises a tread plate for a staircase for a wooden house and a kick plate arranged perpendicular to the tread plate for a wooden house, and is applied to the back surface of the tread plate. It consists of a flat steel plate and a vertical steel plate that hangs down at a right angle from 22 cm of the flat steel plate and is applied to the kick plate. [Selection diagram] Fig. 1

Description

The present invention is an L-shaped reinforcing plate that is used for staircases in wooden houses and is used to reinforce them.

One of the causes of the squealing of stairs in wooden houses is that there is a 7mm square groove on the back of the tread, and a kick plate is inserted into the groove and stopped with a nail (screw nail). This is where the sign 7 points out. In addition, since the surface of the kick board is coated with synthetic resin, a wood bond is used when assembling the stairs, but the synthetic resin has little effect of the bond and is separated by the vibration of rising and falling.

Japanese Unexamined Patent Publication No. 7-34628

For this reason, there is a problem with the construction method of the staircase, and with the vibration or the house becoming old, the connection between the tread board and the kick board is loosened, and the trumbling due to the friction between the tread board and the kick board occurs. Therefore, in view of the above-described problems, the object of the present invention is to prevent tapping if a reinforcing plate is tightened with a designated wood screw to prevent tapping noise of a wooden house stairs.

A flat steel plate that is a reinforcing plate of a wooden house staircase that reinforces a staircase for a wooden house, and includes a step board for a wooden house staircase and a kick board arranged perpendicularly thereto, and applied to the back surface of the tread board, It is a reinforcement plate of the staircase for L-shaped wooden houses which consists of a vertical steel plate applied to the back surface of the kick plate suspended from the end of the flat steel plate.

In addition to the conventional construction, treading can be completely prevented by fixing the L-shaped reinforcing plate to the tread plate and the kick plate with the specified wood screw.

Reference numeral 20 in FIG. 1 of the present invention is an L-shaped reinforcing plate.
As shown in FIGS. 1 and 2, the L-shaped reinforcing plate includes a flat steel plate 1 and a vertical steel plate 3. The flat steel plate 1 is a steel plate applied to the back surface of the tread. For example, the vertical steel plate 3 having a length of 22 cm, a width of 5 cm and a thickness of 2 mm is a steel plate applied to the back surface of the kick plate. 1 and 2, the length of the vertical steel plate 3 connected in a vertical direction from the end of the flat steel plate 1 formed in a racket shape is formed, for example, 20 centimeters. As shown in FIG. 2, the front end side is a racket portion 10 that is widened. Further, a screw hole 2 is formed through the flat steel plate 1 and the vertical steel plate 3.

Based on the above, the vertical steel plate 3 of FIG. 7 is further tightened with wood screws 12, and the racket portion of FIG. 4 is a multi-hole type, and the position varies depending on the height of the stairs. When tightening, always tighten up, down, left, right, alternately. The reason for this is that the material of the tread is made of a laminated material, a compression plate or the like. There are various types of staircases, such as a straight type, a rotating staircase, and a folding staircase. For example, in the case of a rotating staircase, the tread has a triangular shape. 1 in which the length of 1 is 29 centimeters is a standard type M, the flat steel plate 1 on the inner side is called S type, and the outer side is called O type. Therefore, depending on the stairs, three types of L-shaped reinforcing plates are used.

When building wooden houses, use hardware and plate vaults, etc. stipulated in the Building Law. This is a structural problem, and the reinforcing plate for the wooden house staircase of the present invention can be used regardless of the law.
As soon as I wish to apply for an L-shaped reinforcing plate made of steel for stairs for wooden houses.
