Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an expansion joint for covering a gap in a building, and more particularly to a floor expansion joint with a reduced number of parts and improved workability. Is.

[Prior Art] Since a structure is constantly distorted due to expansion and contraction due to temperature changes, unequal subsidence, and earthquakes, etc., a gap structure is configured as a means for preventing destruction of the structure caused by the distortion. Various expansion joints are used as a covering structure.

As an expansion joint for floors / walls of this type, as shown in FIG.
The connecting plate 102 is slidably suspended between the base frames 101 fixed to the side surfaces, and the surface of the connecting plate 102 is covered by the cover plates 103 and 104 and the floor gasket 105 that can expand and contract in the plane direction. The structure having the above structure is used, and covers the gap G formed between the floor a and the wall b so as to be able to expand and contract.

[Problems to be Solved by the Invention] However, in this type of floor joint expansion joint, the base 10
0 and the base frame 101 are fastened to the floor a or the wall b by bolts 107 that are screwed into the anchor plugs 106, and the wall-side base frame 101 is provided with a cover plate 108 for concealing the mounting structure by the bolts 107. Since the wall surface rising portion H to be installed on the front surface is formed, there is a problem that the "edge-shaped structure portion" is always generated around the floor and the design is limited. Further, in general, since the mounting surface of the wall b is wavy, there is also a drawback that the "edge-shaped structure portion" by the fixed construction of the base frame 101 cannot be finished beautifully.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a floor-expansion expansion joint having a new structure, which is simple in construction and has no structure of a wall rising portion.

[Means for Solving the Problems] A floor expansion joint according to the present invention is a floor expansion joint that covers a gap formed between a floor and a wall, in which a support edge is formed at one end edge of a substrate portion, and A base formed by forming a cover member fixing edge on the upper edge of the standing wall portion rising in a letter shape, and fixing the above-mentioned substrate portion to the edge of the floor by fixing means such as bolts,
An engaging edge is formed on an end edge of a plate receiving portion projecting from a frame base having an L-shaped cross section, and the frame base is fixed to a level below the finishing level of the floor of the wall by fixing means such as bolts. And a sliding plate part to be mounted on the supporting edge of the base on one side, and is mounted on the plate receiving part of the base frame on the other side to fit with the engaging edge. A support edge protruding from the connecting plate and one side fixed to the cover member fixing edge of the base, and a pressing edge facing the support edge of the base at the other end. And a cover plate formed by slidably gripping the sliding plate portion of the connecting plate between the holding edge and the supporting edge, and an interposing between the wall side end of the connecting plate and the base frame. And a gasket that hides the base frame mounting structure and a floor gasket that is provided on the upper surface of the sliding plate of the connecting plate to maintain the floor surface and is expandable and contractible. It is an Abstract that consist.

[Operation] According to the above configuration, the base frame fixed to the wall side is mounted so as to be lower than the finishing level of the floor, and the mounting structure of the base frame is concealed by the gasket after the connecting plate is hung. Therefore, not only there is no joint structure protruding from the floor surface, but also the connecting plate can be easily installed.

[Embodiment] An embodiment according to the present invention will be described below with reference to FIGS. 1 and 2.

The floor a forms a gap G with the wall b, and the floor expansion joint of the present invention has a structure that covers the gap G. Reference numeral 1 is a base made of an aluminum pulling member that is fixed to the upper surface of the edge portion on the floor a side in parallel with the wall b surface, and has a support edge 12 and a water blocking plate fitting port 13 at one end edge of the base plate portion 11. And a cover member fixing edge 15 is formed on the upper edge of the standing wall portion 14 that rises in an L shape. The base plate portion 11 of the base 1 is provided with through holes 16, 16 for inserting fixing bolts in the longitudinal direction, and at the same time, the through holes for inserting the fixing bolts are attached to the anchor plugs 91 mounted on the floor a. The bolts 92 inserted from 16 are screwed together and fixed.

On the other hand, on the surface on the side of the wall b, a base frame 2 made of an aluminum drawn object is fixedly installed so as to face the base 1, and the frame base 21 having an L-shaped cross section has an upper end at the floor finishing level F. So that the fixing bolts pass through holes 22, 22 in the longitudinal direction.
, And the bolts 94 inserted through the fixing bolt insertion through holes 22 are screwed and fixed to the anchor plugs 93 formed on the wall surface b.
An engaging edge 24 is formed on the edge of the plate receiving portion 23 that projects from the. Further, reference numeral 25 is a water stop plate fitting port formed at the lower edge of the frame base 21.

Reference numeral 3 is the support edge 12 of the base 1 and the plate receiving portion 23 of the base frame 2.
A support plate 32 which is a connecting plate suspended above and constitutes a sliding plate part 31 mounted on the support edge 12, and on the other side is mounted on the plate receiving part 23 and fitted with the engaging edge 24. And a gasket fitting groove 33 is formed on the edge of the support edge 32.

Reference numeral 4 is a cover plate having one side fixed to the cover member fixing edge 15 of the base 1, and the cover plate is at the same level as the surface of the surface base material c via the fixing screw 45 on the cover member fixing edge 15. Is fixed to the support edge 12 at the other edge.
And a pressing edge 41 facing the sliding plate portion 3
1 is gripped between the pressing edge 41 and the support edge 12.

A gasket fitting groove 33 is formed at the end of the connecting plate 3 on the wall b side.
The gasket 5 that fits with is interposed between the wall b and
In addition to hiding the heads of the bolts 93, a floor gasket 6 which is capable of expanding and contracting in the lateral direction is provided between the pressing edge 41 of the cover plate 4 and the step wall on the upper surface of the sliding plate 31 so as to maintain the floor surface F. The floor gasket 6 is fitted with a fitting projection 61 at the end of the floor gasket 6 and the other end 62 is fitted under the holding edge 41.

Further, reference numeral 7 is a floor surface material provided on the surface of the surface base material c on the floor a side, and the floor surface material 7 is continuously stuck to the front surface of the cover plate 4.

Between the water blocking plate fitting ports 13 and 25 of the base 1 and the base frame 2, fitting edges 81 and 81 having water blocking plates 8 made of soft synthetic resin formed at both ends thereof are fitted and fixed. It becomes.

In the expansion joint for floor rotation having the above-mentioned configuration, the base frame 2 on the wall b side on which the connecting plate 3 is hung is installed to be lower than the floor level F, so that after the base frame 2 is installed around the floor surface. Never appears in.

[Advantages of the Invention] As described above, the expansion joint for floor according to the present invention does not have a joint structure protruding from the floor surface, so that not only is there a problem that the indoor design is limited, but also by the attachment of the connecting plate. Since the mounting structure of the base frame is concealed, it has features such as easy construction, and the practical effect after implementing the present invention is extremely large.
