Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to improvement of expansion joints for covering gaps in buildings, and more particularly to a waterproof gutter for expansion joints used in floor expansion joints. .

[Prior Art] Buildings are constantly expanded and contracted due to temperature changes, strains are generated due to unequal settlement, earthquakes, etc. Therefore, various expansions and contractions are used as a structure for covering a gap structure configured as a means for preventing the destruction of the structure caused by the distortion. A joint is used, and a third joint has been used to prevent rainwater and domestic water from entering from the expansion joint.
A water stop plate as shown in the figure is used.

That is, the conventional water blocking plate 50 is provided between the pair of frame bases 51, 51 that are fixedly fixed to each other on both edges of the floors a, b of the building with the gap G for absorbing strain of the building interposed therebetween. In this structure, a band material made of a soft material wider than the gap G is bent and attached in a U shape. The cover plates 52 are hung on the both frame bases and stopped by the hanging members 53. The expansion joint is worn.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional water stop plate for expansion joints, since it is necessary to configure the flexure amount that can correspond to the maximum separation displacement of the gap G, the flexure amount in the normal state is large. Not only does the material cost rise because of the need to take water, but also the water stop plate 50
After installing between the frame bases 51, 51, there is a problem that the expansion joint cannot be operated from a gap in the ceiling below, for example.

The present invention has been made in view of the above-mentioned problems, and it is possible to perform various operations on the expansion joint from the gap in the ceiling below the floor even after attaching the water shutoff gutter, and to an expansion joint used for gaps of any width. It is an object of the present invention to provide a water shutoff trough for expansion joints having a new structure that can use the same standard product.

[Means for Solving the Problems] A waterproof gutter for expansion joints according to the present invention includes a pair of frame bases facing each other at both edges of a floor of a building with a strain absorbing gap interposed therebetween. In the expansion joint, both side edges or one of the side edges is provided between the two frame bases with a covering plate slidably displaceable with respect to the frame bases. A groove-shaped trough stop port is formed over the entire length in the longitudinal direction at the innermost end of each of them, and a fitting ridge provided on the back surface of the water stop trough having a groove-shaped cross section is fitted into each trough stop port. However, the gist is to have a structure in which the water receiving surface of the water shutoff gutter is fixed so as to be located at the rear of the innermost end of the frame base.

The waterproof gutter is preferably made of hard or semi-hard synthetic resin.

Further, the fitting ridges can be provided not only over the entire length of the back surface of the water shutoff trough but also at a part thereof.

[Operation] According to the above configuration, since the waterproof gutter is independently attached to both frame bases facing each other in the gap, it can be used regardless of the width of the gap. It can be implemented by standard products, which is economically advantageous. In addition, since the waterproof gutter is independent, a continuous opening is formed inward of the gap between both the waterproof gutters, so that it is possible to work from the back side of the gap even after installing the waterproof gutter. become.

[Embodiment] The first embodiment of the waterproof gutter for expansion joints according to the present invention will be described below.
It will be described with reference to FIGS.

FIG. 1 shows a vertical cross-sectional view of the construction state, and the gap G
On both floor surfaces a and b on the same level with the frame sandwiched between them, the frame bases 1 and 1 made of aluminum pulling objects are provided at their edge portions, respectively.
Are fixed facing each other. Both frame bases 1 and 1 are mounting frame parts 2
A hanging rod locking groove 3 having a downward groove shape is formed on the inner edge of the whole length of the hanging rod locking groove 3, and a groove-shaped gutter fastening port is formed behind the hanging rod locking groove 3 and has a narrow edge. It is formed over the entire length in the longitudinal direction. Further, a flat sliding step portion 5 is formed on the front surface of the mounting frame portion 2 and extends outside the gap G.
A cover plate 6 having the same level as the floor finishing surface F is mounted on the sliding step portions 5, 5 of both frame bases 1, 1 with a sufficient sliding stroke between the both edges and the step portion edges 7, 7. It will be put up. The covering plate 6 is provided with sliding rollers 9 and 9 which are rotatably projected at both ends of a hanging rod 8 which is longer than the width of the gap G (accurately, a length exceeding the widening displacement allowance of the gap is required). A mounting screw 10 that is engaged with the suspension rod locking grooves 3 and 3 of the frame bases 1 and 1 respectively, and is inserted from the plate surface of the cover plate 6 into a screw hole 10a that is screwed in the center of the suspension rod 8. Be tightened and fixed. Floor gaskets 11, 11 which are expandable and contractible in the width direction are interposed between both edges of the cover plate 6 and the step edges 7, 7.

As shown in FIG. 2, the waterproof gutter 12 of the present invention has one oblique edge 14 of one side of the gutter body 13 having a U-shaped groove section.
Fitting ridges 15 which are fitted on the rear surface over the entire length thereof by elastically deforming the trough attachment ports 4 of the frame bases 1 and 1
The waterproof gutter 12 is formed of a hard or semi-hard resin such as vinyl chloride resin. still,
The fitting ridge 15 of the waterproof gutter 12 may have a projecting structure which is not continuous over the entire length.

In the waterproof gutter 12 having the above-described configuration, the gutter body 13 is located behind the inner edges (arrows A) of the hanging rod locking grooves 3 and 3 of the frame bases 1 and 1, so that the floor gasket 11 is provided along the floor surface. The water that has entered from between the gaps drops from the inner edge portion to the gutter main body 13 to receive all the water and does not leak to the outside.

Needless to say, the waterproof gutter 12 of the present invention can be used by stacking it with the conventional waterproof plate described above by adding an attachment port to the frame base.

[Effects of the Invention] As described above, the waterproof gutters for expansion joints according to the present invention have various shapes regardless of the width of the gap because the waterproof gutters are independently attached to both frame bases. Since it can be used for expansion joints of, it can be implemented with a single standard product, which is extremely economically advantageous, and enables various operations from the back side of the gap even after mounting the waterproof gutter,
It has a feature of facilitating the installation work of the expansion joint, and the practical effect after implementing the present invention is extremely large.
