Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an expansion joint for covering a gap in a building, and more particularly to an expansion joint having a large strain absorption width.

[0002]

[Prior art]

 Buildings are constantly distorted due to expansion and contraction due to temperature changes, unequal subsidence, earthquakes, etc. Although a large structure has a gap structure for the purpose of preventing damage to the building due to the distortion. Conventionally, various expansion joints have been used as a structure for covering this gap.

[0003]

[Problems to be solved by the device]

 In recent years, as the size of buildings has increased and the height of the building has increased, the width of the gap has become wider, so the strain in the vertical and horizontal directions also increases, and if an expansion joint with a large strain absorption width is configured, the overall load of the expansion joint increases. There were problems, and there was a demand for simplification and weight reduction of the structure.

The present invention has been made in view of the above problems, and is capable of sufficiently absorbing large strains in the vertical and horizontal directions and in the inclination direction, resulting in a lightweight and simple structure, and to a portion where the joint construction surfaces are orthogonal to each other. It is an object of the present invention to provide an expansion joint suitable for construction.

[0005]

[Means for Solving the Problems]

 The expansion joint according to the present invention is an expansion joint provided on a surface in the direction orthogonal to the strain absorbing gap of a building, and one of the two constructions sandwiching the gap is opposed to the surface of the adjacent construction. A frame base fixed to the edge of the building and having a sliding groove extending in the longitudinal direction on the surface, and a hinge member mounting groove fixed to the surface of the other building and extending in the longitudinal direction on the surface And a hinge base composed of the above, and a base is slidably fitted in a sliding groove of the frame base, and a columnar engaging projection is formed integrally with the base. A child, a hinge member in which a base is fixed to a hinge member mounting groove of the hinge base, and a columnar pin shaft is integrally formed at a tip of a support arm extending from the base; The mating protrusions are slidably engaged with the sliding grooves formed on the back surface side, and are attached to the frame base through the sliders, respectively. A hanging rod that is slidable in a lateral direction and tiltable, and a pin rod of the hinge member that is pivotally installed in an axial hole formed at one end so as not to be pulled out, and the hanging rod. The gist of the present invention is that the rods are fixed in parallel in the longitudinal direction at appropriate intervals and are composed of a covering plate that covers the gaps of the building.

[0006]

[Action]

 Therefore, when the structure is relatively displaced through the gap due to expansion and contraction due to temperature change, unequal settlement, and earthquake, etc., the slider is fixed on the frame base and the hinge base fixed with the gap of the structure. Since the hinge member is pivotally installed and fixed, and the cover plate is fixedly installed on the slider and the hanging rod that is installed on the hinge member, the direction in which the gap is extended by the slider, the tilt direction, and the lateral direction. In addition, the structure is such that it is slidably or angularly displaced in the tilt direction via the hinge member, and the strain can be sufficiently absorbed by the sliding range of the slider and the tilt of the member that interferes with the slider.

【Example】

 An embodiment of an expansion joint according to the present invention will be described below with reference to the drawings. 1 to 4 show an embodiment of an expansion joint for outer walls of buildings a and b which are orthogonal to each other with a gap in between, and a frame base 1 made of an aluminum form material is provided adjacently with a gap in between. The frame fixing anchor 2 is fixed to the end of the building a which faces the surface of the building b. The frame base 1 is formed by integrally molding sliding grooves 3 having locking edges 4 in the longitudinal direction along the inner side edges.

The base portion 6 of the slider 5 is fitted in the sliding groove 3 of the frame base 1 so as to be slidable in the longitudinal direction (arrow A), and the base portion 6 is projectingly provided on each of the sliders 5. A column-shaped engaging projection 7 having a substantially cylindrical cross section is integrally formed in the longitudinal direction on the back surface of a hanging rod 8 hung on the frame base 1 and slidable in the direction of arrow B with respect to a sliding groove 9. In addition, it is fitted so as to be tiltable in the direction of arrow C.

On the surface of the other building b, a hinge base 10 made of an aluminum frame material is fixed by a frame fixing anchor 2 at a position corresponding to the extension of the surface of the adjacent building a. Set up. The hinge base 10 has a hinge member mounting groove 11 having a holding edge 12 formed on the surface in the longitudinal direction, and a cover plate locking edge 13 formed integrally along the outer side edge. Become.

The hinge member mounting groove 11 of the hinge base 10 is fitted with a base 14 having a bolt 15 protruding from the hinge member 16 so that the fitting position can be adjusted in the longitudinal direction (arrow D). The through hole 18 formed in the above is externally inserted into the bolt 15, and is fastened by a nut 19 from the outside. The hinge member 16 is provided with a supporting arm 20 that can swing freely without interfering with the sliding groove 9 of the hanging rod 8 and projects obliquely forward from the base portion 17. A cylindrical pin shaft 21 which is sufficiently longer than the groove width of the sliding groove 9 is integrally formed at the tip, and the pin shaft 21 has a shaft hole 22 formed in a side wall near one end of the sliding groove 9. It is pivotally mounted (arrow E) with respect to. The shaft hole 22 is formed with slits 23, 23 into which the plate thickness of the support arm 20 can be inserted sufficiently from the end of the sliding groove 9. As shown in FIG. The pin shaft 21 can be inserted and installed in the shaft hole 22 by using 23 and 23.

A cover plate 24, which covers one end of the hanging rod 8 and the gap between the buildings a and b, is fastened to the front side of the hanging rod 8 by a cover fixing screw 25. An engaging edge 26 formed in a stepped manner on the side edge is engaged with the cover plate locking edge 13 of the hinge base 10, and a plurality of hanging rods 8 arranged in parallel with the cover plate 24 are predetermined. The structure is fixed with a space of. In addition, a packing fitting groove 27 which is located on the rear surface of the edge of the covering plate 24 on the side of the building a and faces inward is integrally formed, and a packing 28 is fitted in each packing fitting groove 27 to form a lip portion. The structure is such that 29 is slidably in close contact with the surface of the building a.

Reference numeral 30 is a waterproof gutter formed of a soft material such as vinyl chloride resin, and has both side edges between the frame base 1 and the building a and the hinge base 10 and the surface of the building b. It is fixed with sufficient bending.

The expansion joint having the above-described configuration is arranged between the frame base 1 and the hinge base 10 that are fixedly installed with a gap between the buildings a and b, and the direction in which the gap extends through the slider 5 and the hinge member 16. Since the covering plate 24 is fixedly mounted on the hanging rod 8 which is slidably movable in the tilting direction and the lateral direction, the covering plate 24 having a sufficient width for covering the gap is adjusted to the width of the covering plate 24. By changing the length of the hanging rod 8, it is possible to deal with a building having a large gap, and at the same time, the displacement in the extending direction of the gap can be sufficiently absorbed.
