Description

[Detailed Description of the Invention] Background of the Invention The present invention provides an elastic structure supporting both sides of the joint gap for exchange joints such as ramps of overpasses, bridges, sidewalks, and floors of multi-story parking lots. The present invention relates to a device for splicing with at least one elastic cellular band made of a material.

Discussion of the Prior Art In the prior art, an example of a device of this type is designed in the form of a sealing strip, which is fixed in place by tightening a non-slip fitting on the side of the joint or on the retaining means. The strip had means on the sides thereof. Such a sealing strip in the center of the intersection is formed with a horizontal channel, making it easier for the sealing strip to be compressed or slid as the sides of the joint move closer together (and to In other prior art designs that fill the joint gap, the sealing strip is generally in the form of a hollow body with deformation cells that cause the hollow body to slide or fold as the joint gap becomes smaller. It was easy to do.

However, both prior art methods were found to have the following drawbacks. In other words, the sealing strip flexes and sinks into the joint.
It should be lower than the top level of the side of the joint. The larger the width of such a 1.1 gap of subsidence, the more pronounced it becomes. In addition, the strip may block the position above the level, or both forms of deformation may occur simultaneously, creating a danger to pedestrians and others walking on the sidewalk in such cases, and the sunken portion of the strip may become a source of debris. Such debris will shorten the operating life of the sealing strip.

SUMMARY OF THE INVENTION One object of the invention is therefore to
The aim is to design and further develop the joint so that, no matter where the joint is located, there is no danger to anyone walking or driving on the equipment.

Yet another object or goal of the invention is to prevent as much dirt from accumulating as possible, whatever the width of the joint gap.

To accomplish these and other objects of the invention, the upper side of the sealing strip is comprised of a number of interconnected planar surfaces aligned in a single plane no matter where the strip is in its operative position. There is.

This design of the ζ strip according to the invention is intended to ensure that the surfaces of the gap compensating means are always at the same level, while e.g. the strip is partially or fully extended. or when compressed, compressed or 4
, so that its upper surface is in the same plane as the horizontal plane, whatever the degree of extension. (Therefore, the risk of accidents is significantly reduced. Smooth movement takes place on the sides of the joint gap. Also, even when it rains, muddy water does not accumulate, and in cold climates A further advantage of the gap compensation or emphasis of the present invention is that, whatever the joint condition, no debris buildup will generally occur on the sealing strip. .Debris build-up is a common cause of strip deterioration.The sealing strip is held firmly in place at the end in specially designed retaining means that are also flush with the top surface of the sealing strip. They are lined up.

Other useful examples and details of the invention will become apparent from the description of the embodiments with the aid of the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION In cross-section 17 The joint or sealing strip 1 has a central part of construction which is generally characterized by being made of cells of a special design.

Web or cell walls 6.6a 16b, 9 and 9a
All of them are designed to spread out and converge with each other (
The self is formed with an equilateral rhombic cross-section in the central part thereof, and one vertex of this quadrilateral faces toward a flat or planar object 13a. There are cells 8 on both sides of such a cell, and each cell 8 has a quadrilateral cross-sectional shape. In this example, each such quadrilateral is generally in the form of a scalene trapezoid, with one of its vertices facing planar surface 13 in one quadrilateral and surface 13b in the other quadrilateral. ing.

Planar surfaces 13 and 13b are associated with further planar surfaces 11 and 14. The planar surfaces are all in a single plane and are separated from each other by short notches. The shape of these notches is distinctly V-shaped.

At the end, the planar webs 11 and 14 are connected to the edge web 1.
5, its edge web 15 forms a seam 1- with an outwardly directed lip 3 at a lower level than the planar surface.
Alternatively, the contact surface 2 is formed.

The lip 3 is followed by relatively thin elastic feathers or edges 4 which are bent inwards towards planar bodies 11 and 14. Such a feather has a bead 5 at the end. The beat 5 may be made of an elastic material if necessary.

The sealing strip 1 is fixed or locked in reinforcements 17 provided at predetermined positions on both sides along the end of the joint gap member 16. This retaining means 17 is generally U-shaped, the longer leg 18 of which generally extends up to the upper surface 10 of the installed sealing strip 1, where said leg is bent round and pointing downwards; It forms a hook-shaped head 19 whose unrestrained end takes the form of a shelf for sealing against the abutment surface 2 of the lip 1.

The other leg 20 is somewhat shorter in length and may be slightly narrower towards the longer leg 18a. lip 3
, elastic feathers 4 and beads 5 (see Figure 2)
is housed in a recess 29 formed by the legs 18 and 20, so that the sealing strip 1 is locked in place by a force fit and cannot be removed or lifted out of position except by special purpose tools. It is designed not to.

The holding means 17 has mooring means, which in this embodiment are connected to a rail 2 joined to the outer bottom of the holding means 17.
In addition to this design, other well-known forms of anchoring means may be used as the retaining means 17.
It can also be used for.

The reader will see from FIGS. 2 and 3 that the upper surface 10 of the sealing strip or band 1 is always flush with the upper edge of the side of the joint gap in the member 16. Bent head 19 of holding member 17
Alternatively, the hooks are also aligned with this plane, creating a generally uninterrupted flat surface except by short notches 12, which do not impair the planar shape of said upper surface.

This form of the invention is considered a simple and inexpensive means of compensating or filling joint gaps. Depending on the actually applied loads, the webs or hill walls forming the planar surface are reinforced, for example by providing reinforcing ribs, etc. or by providing metallic or non-metallic reinforcements. Write reinforcement.

A further embodiment of the apparatus of the invention is shown in FIGS. 4-6. In the central part, the sealing strip in this case comprises cells 24 and 25. Two cells 24 next to each other have a triangular cross-section, with the apex of the triangle pointing toward the top surface of the strip, while
The two cells with triangular cross-sections adjacent to them have their bases on top. The upper surface 10 has planar surfaces 11a and 14.
Two central planar surfaces 13c and 13d adjacent to a
formed by. The web 23 or the cell wall is connected laterally with an upper web 30 which is designed to be particularly thick. In this case too, there is an abutment surface 2 or a shelf, and a lip 3
The feather 4 continues to the feather 4, and the cross section of the feather 4 becomes thinner, and points upward to a planar shape 11a or 14a.

At the end of the feather 4 or edge there is a bead 5.

This sealing strip is locked in place in exactly the same way as the strip shown in FIG. 1, the only difference being that the short leg 20a is rounded to form a fold 27. The unconstrained end of the fold or head 27 is bent down at a right angle to form a leg 28 . Again, there is a tether 21 which is locked in place no matter what specific member 16 forms the side of the joint gap 22.

With this device as well, as shown in FIG. 6, the sealing strip 1a moves smoothly in the same plane relative to the end of the joint gap in the member 16 when it is compressed.
