JPH07279538A - Doorsill and installation structure for doorsill - Google Patents

Abstract

PURPOSE:To obtain an installation structure which facilitates installation operation and is free from the generation of squeak even in stamping, by forming an anchor striking hole on a doorsill and striking an anchor from an installation striking hole in a demountable manner on a closing plate. CONSTITUTION:A stay 12 is welded, keeping an interval, on the reverse surface of a steel body 11. Then, an L-shaped steel plate 13 is welded on the stay 12, and an anchor striking hole 14 is drilled on the L-shaped steel plate 13. Then, the L-shaped steel plate 13 is placed on a concrete foundation 2, and drilling is carried out on the foundation 2. Then, an anchor 3 is inserted into a hole 21, and a pin P is inserted, and the foot part is spread by the tapping by a hammer. Then, the pin P is pulled out. A closing plate 17a is installed in a demountable manner in a pulling-out/striking hole 13a, and the intrusion of rainwater, dust, etc., is prevented. Accordingly, a shoe slide can be installed only by striking the anchor 3 into the anchor striking hole 14, and the execution work can be carried out easily.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel slide and a structure for mounting the wheel slide, and more particularly to a structure which can be easily attached to a concrete foundation by an anchor.

[0002]

2. Description of the Related Art Conventionally, for example, JP-A-2-240386.
In Japanese Patent Laid-Open Publication No. 2003-242, there is known a mounting structure of a sliding member in which a supporting metal member is fixed to a base frame member for receiving concrete through bolts, and the sliding member is mounted on the supporting metal member by bolts. In this type of mounting structure, it is necessary to align the base frame material and the supporting metal fittings, which requires time and effort for construction, and in addition, mounting the mounting structure There was a problem that the strength was not high. Therefore, generally, the slinging is fixed to the vertical frame or integrated with the vertical frame, and the vertical frame is used for mounting to the building frame.

[0003]

However, as in the conventional case, the sliding member is fixed to the vertical frame or is integrated with the vertical frame.
When mounting to the building frame with a vertical frame, a gap is likely to be created between the gutter and the concrete foundation below it, and if a gap is created, if the gutter is stepped on,
There was a drawback that the slipper would bend and creak.

The present invention has been made by paying attention to the problems in the conventional gears and the attachment structure of the gears, and the purpose thereof is to attach the conventional gears and the attachments of the gears. It is an object of the present invention to solve the problems in the structure, provide an attachment structure that is easy and easy to attach, and that does not cause squeaking even when stepped on, and an attachment structure for a slide.

[0005]

In order to achieve the above object, the present invention set forth in claim 1 is characterized in that an anchor driving hole is provided.

According to the second aspect of the present invention, there is provided an anchor driving hole, and a closing plate is detachably attached to the anchor driving hole.

Further, the attachment structure of the present invention as set forth in claim 3 uses the chamfer as claimed in claim 1 or 2, and the chamfer is made by driving an anchor from an anchor driving hole of the chamfer. It is characterized by being attached to a concrete foundation.

In the present invention, the material of the sliding gear is
Although not particularly limited, for example, in addition to metals such as steel, stainless steel, aluminum and brass, synthetic resins such as FRP can be used.

In the present invention as set forth in claim 3, the material of the anchor is not particularly limited.
Metals such as steel, stainless steel, aluminum and brass can be used.

[0010]

In the present invention, the anchor driving hole is provided, so that when the present invention sliding tool is attached to the concrete foundation, the anchor is driven into the anchor driving hole of the present invention sliding tool. The sole of the present invention can be attached to the concrete foundation by itself.

In the present invention, the anchor driving hole is provided, and the closing plate is detachably attached to the anchor driving hole. Therefore, when mounting the present invention sliding tool on the concrete foundation. After the closing plate is removed from the anchor driving hole of the present invention and the anchor is driven into the anchor driving hole to attach the present invention sliding door to the concrete foundation, the closing plate is attached to the anchor driving hole to fix the anchor driving hole. It is possible to prevent rainwater and dust from entering the anchor driving hole.

Further, in the attachment structure of the present invention as set forth in claim 3, the gear slide according to claim 1 or 2 is used, and the anchor is driven through the anchor driving hole of the gear slide. Is attached to the concrete foundation, the drawer is firmly attached to the concrete foundation, and there is no risk of the drawer sliding and bending.
