Abstract

PURPOSE:To prevent peeling of a tile by a method wherein a number of ribs and protruding lock pieces are formed on a tile mounting sheet secured to a cover sheet positioned facing the tile mounting sheet with a gap therebetween equal to the gap of a building. CONSTITUTION:Frame base beds 1 are positioned facing each other with a gap G. A covering coupling sheet 8 and a packing 9 are engaged with each other between a bottom sheet part 3 and a cover sheet 6, and a slide allowable width is left therebetween. A tile mounting sheet 11 is secured on the surface of the cover sheet 6, and a number of microrising ribs are formed in a laterally and longitudinally aligned state on the tile mounting sheet 11. Locking pieces 18 engaged with a laterally extending dovetail groove 17 are formed on the rear of a tile 13, and are laterally and longitudinally cut and rise and are protruded and engaged with the dovetail groove 17 of the tile 13. This constitution prevents the occurrence of an accident, e.g. peeling, a drop, of the tile.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in the decorative structure of a cover plate in an expansion joint device for covering a gap in a wall of a building.

[Prior Art] Buildings are constructed with gap structures as a means of preventing destruction of buildings due to expansion and contraction due to temperature changes, uneven settlement, and distortion due to earthquakes, etc. A cover connecting plate is attached between a pair of frame bases fixed to the ends of the cover plate, and the cover connecting plate is sandwiched from both sides by cover plates. Therefore, the large line that divides the design of the building by expansion joints on the wall of the building is cursed, so conventionally in this type of expansion joint, the surface of the cover plate and covering connecting plate is covered with tiles or other surface materials of the building. Apply the same or similar surface material to harmonize the design.
Attempts are being made to resolve the divide.

[Problems to be Solved by the Invention] However, when the cover plate and covering plate are finished with the same material as the surface of the building as described above, distortion occurs in the expansion joint part due to constant expansion and contraction of the gap and displacement. At the same time, various forces are applied, and in many cases it is not possible to use the same or similar base material as the building material.For example, when tiles are used as a surface material, the tiles tend to peel off more easily than other parts, which poses safety concerns. I had a problem with that.

In view of the above problems, the present invention has a structure that has excellent design consistency with adjacent wall surfaces, has a gripping force of one surface material, and has excellent safety, and can make the gap structure of a building less noticeable. The object of the present invention is to provide a decorative structure for a cover plate in an expansion joint device.

[i! ! [Means for Solving Problem II] The decorative structure of the cover plate in the expansion joint device according to the present invention is arranged between a pair of frame bases which are fixed oppositely to the edges of both buildings with a gap between them. In addition to slidably installing the covering connecting plate on the
A cover plate is fixed and extended from the edge of both frame bases toward the front surface of the covering connecting plate, and the surface of the covering connecting plate and/or the cover plate is covered with a tile surface material. In the expansion joint device, a tile mounting plate having a plurality of locking pieces cut and raised vertically and horizontally at predetermined intervals on one surface is fixed to the surface of the covering connecting plate and/or cover plate, and the tile mounting plate is The gist of this method is to attach a tile having at least one dovetail groove extending laterally on the back side of the locking piece by engaging the dovetail groove, and attaching the tile using cement mortar joints.

In addition, each locking piece of the above tile mounting plate is a parallelogram,
It is preferable to engage with the dovetail groove of the tile and the upper groove wall thereof, and furthermore, it is preferable to provide a large number of micro-raised rib structures on the surface of the tile mounting plate to increase the bonding area.

[Function] That is, according to the above configuration, the surface decorative structure provided on the cover plate and/or covering connecting plate that face each other with substantially the same gap as the gap in the building is able to prevent the tile mounting plate fixed to the adhering surface. Since the engagement structure by the locking pieces and the dovetail grooves of the tiles are in a securely fitted state, when the joints are filled between the tiles, accidents such as individual tiles peeling off and falling do not occur.

Therefore, the gripping force of one surface material is large and the structure exhibits excellent safety.

[Example] An example of a decorative structure of a cover plate in an expansion joint device according to the present invention will be described below with reference to the drawings.

Fig. 1 shows an expansion joint in which a decorative structure according to the present invention is applied to the surface of a cover plate, and reference numerals 1°1 indicate anchors at each step of the building a, a, b, with a gap G in between. These are frame bases with a substantially U-shaped cross section to which a bottom plate part 3 is fixed via bolts 2, and are opposed to each other with one gap in between. It protrudes from the finish level of the base material C. A screw 5 is attached to each of the front edges 4.
A cover plate 6 is attached to which the cover plate 6 is fastened.
A packing groove 7 formed on the back surface of the end portion of the cover plate 6 is fitted with a packing 9 that closely slides on the surface of a cover connecting plate 8, which will be described later. The covering connecting plate 8 is connected to the both frame bases 1, 1.
The inner edge 810.10 is provided at the inner end of the bottom plate portion 3, and is spanned so as to leave a sufficient sliding width on both side edges.

In addition, tile mounting plates 11 shown in FIGS. 4 to 7 are fixed on the surfaces of the double-sided bar plates 6 and 6, respectively, with screws 12, and the same as the exterior material Tiles 13 are attached and adhered with cement mortar joints 14.

The string tile mounting plate 11 has a large number of slightly raised vertical ribs 15 and horizontal ribs 16 arranged in parallel vertically and horizontally, and a locking plate that fits into a dovetail groove 17 extending in the horizontal direction formed on the back surface of the tile 13 shown in FIG. The pieces 18, 18... are cut and raised vertically and horizontally at predetermined intervals.

Each stopper piece 18 has a parallelogram shape with upper and lower edges at an angle of 45 degrees, and is configured to engage with the upper groove wall of the dovetail groove 17 of the tile 13. The tiles 13 can have various vertical and horizontal widths as shown in FIG.
The dovetail groove 17 formed on the surface is the locking piece 18 of the tile mounting plate 11.
Needless to say, it is a condition of the configuration that the pitches in the vertical direction correspond to each other.

Incidentally, reference numeral 19 denotes a water stop plate made of a flexible material whose both ends are fitted into the inner edges of the frame bases 1, 1 at 10 degrees.

The expansion joint device having the above structure covers the front surface with the tile 13 that covers the surface of the cover plate 6, and when the tile 13 engages the dovetail groove 17 with the locking piece 18 of the tile mounting plate 11. Since it is adhesive, it has high integrity and will not peel off easily. Further, by pasting the decorative tiles C on the base material surfaces of the buildings a and a so as to be on the same level as the tiles 13 on the cover plate 6, the surfaces of these parts can be integrated.

Furthermore, tiles 13 as a surface material can be attached to the surface of the covering connecting plate 8 of the expansion joint with a structure similar to that of the cover plate 6 via the tile mounting plate 11.

In this embodiment, a structure for a wall surface has been described, but it goes without saying that the present invention can also constitute a similar expansion joint for a ceiling surface.

[Effects of the Invention] As described above, the decorative structure of the cover plate in the expansion joint device according to the present invention is such that the decorative surface structure provided on the cover plate facing with substantially the same gap as the gap of the building is covered. Because it is securely engaged with the engagement structure of the tile mounting plate that is fixed to the mounting surface, accidents such as peeling and falling do not occur, and it is especially suitable for the structure of expansion joints used in high-rise buildings. It is useful and the effects after implementation of the present invention are extremely large.
