[Technical field to which the device belongs]

 The present invention relates to improvement of Utility Model Registration No. 3006815 "Concrete Border Block Joint Plate" proposed by the present inventor.

[0002]

[Prior art]

 The structure of the joint plate proposed by the present inventor has the same shape as the connecting surface of the boundary block, and the joint plate body such as a rubber plate or a rubber-based foam body has a circular or square shape for bonding on both sides thereof. A groove hole is formed, and one or two filling holes are formed so that the groove hole and the peripheral surface of the joint plate body communicate with each other. When constructing using this, place a number of boundary blocks side by side first, insert the joint plate main body between the boundary blocks to make them adhere, and then fill the perforated surface of the upper part of the joint plate main body. Glue was injected through the holes to fix both sides to the boundary block.

[Problems to be solved by the device]

 However, when the joint board is inserted between the boundary blocks arranged in advance, if the clearance between the boundary blocks is narrow, the rear boundary block must be moved to secure the necessary clearance, which is troublesome. there were. Also, when the boundary block gap is too wide, after inserting the joint plate, it is necessary to press the rear boundary block to bring them into close contact with each other.Fine adjustment of the boundary block gap is required when inserting the joint plate. I had to do it. Moreover, when arranging the boundary blocks, if there is a dent, the joint plate will fall downward between the boundary blocks, and it will take a lot of time to lift the joint plate, and if there is a protrusion, the joint plate will be the boundary block. I had to get out of the upper and side parts of the building, and every time I had to position it so that it would fit well by grounding the ground between the boundary blocks. Further, if the joint board is not adhered between the boundary blocks, there is a problem that a large amount of adhesive is used, or the adhesive does not serve its purpose and the adhesive strength is drastically reduced.

The present invention provides a joint board for concrete boundary blocks in which the boundary blocks are arranged and the joint boards are also brought into close contact with each other at the same time, and the work of fine adjustment of the gap and the positioning of the joint board are omitted to improve the work efficiency. The purpose is to provide. Another object of the present invention is to provide a joint boundary block joint plate which always holds a fixed position of the joint plate so as not to be displaced or come off and to always obtain a stable adhesive force.

[Means for Solving the Problems]

 The present invention has been made in order to solve the above-mentioned problems, that is, one end face of the joint plate main body is provided with the adhesive groove and the upper surface of the joint plate main body in the same manner as in the conventional case. A filling hole or filling groove is formed in advance, and an adhesive layer composed of an adhesive and a release paper or an adhesive layer of a double-sided sheet is provided on the other end surface of the joint plate body. As the joint plate body, as in the conventional case, a rubber plate or a rubber-based foam extruded product, or a crushed product of a rubber plate or foam solidified with a synthetic resin or the like is used.

[0006]

[Embodiment of device]

 Embodiments of the present invention will be described below with reference to the drawings. (1) is a joint plate body having the same shape as the connecting surfaces (51), (52) of the boundary block (5), and the material thereof is a rubber plate or a product without rubber foam, or a rubber plate or foam. Use a crushed body molded with a synthetic resin. The joint plate body (1) has a thickness of about 15 mm. The expansion ratio of the rubber-based foam is preferably in the range of 3 to 20 times, but 7 times is the best. (2) is a circular bonding slot formed in the one end surface (11) of the joint plate body (1), and its depth is preferably 0.5 mm to 2 mm. The depth of the slot (2) is the thickness of the adhesive layer, and the larger the size, the larger the adhesive area. Further, the shape of the slot (2) is not limited to the above-mentioned circle, but may be a polygon such as a quadrangle or a hexagon. (3) is a filling hole formed from the upper surface (13) of the joint plate body (1) to the slot (2), and the filling hole (3) is for pouring an adhesive or the like into the slot (2). It is for. Reference numeral (4) is an adhesive layer provided on the other end surface (12) of the joint plate body (1). The adhesive layer (4) is an adhesive agent (41) and a release paper (42) attached thereon. Or a double-sided sheet is used. As shown in FIG. 3, a filling groove (3 ′) may be formed instead of the filling hole (3), and the filling groove (3 ′) is formed from above the joint plate body (1). The hole (2) is drilled up to near the center, and its shape is a semicircular or U-shaped cross section.

Next, a method of constructing the boundary block (5) using the product of the present invention will be described. First, the release paper (42) of the adhesive layer (4) provided on the other end surface (12) of the joint plate body (1) is peeled off [see FIG. 4 (a)]. Before construction, attach it to the connecting surface (51) of the boundary block (5) [see Fig. 4 (b)]. The boundary blocks (5) to which the joint plate body (1) is attached are sequentially pressed, and the boundary blocks (5) are arranged while ensuring a state in which the boundary blocks (5) are in close contact with each other via the joint plate body (1). Then, an adhesive or the like is injected from the filling hole (3) formed in the upper surface (13) of the joint plate body (1) [see FIG. 4 (c)]. After the adhesive is filled in the groove (2), the adhesive or the like may be sequentially injected in the same manner from the filling hole (3) of the next joint plate body (1). As described above, the present invention product simply attaches the joint plate body (1) to the boundary block (5) before arranging the boundary blocks (5), and always holds the joint plate in the orientation. All that is required is to arrange (5), and the displacement and disengagement of the joint plate body (1) as in the conventional case is eliminated. Further, since the boundary block (5) and the jointing plate body (1) are adhered and fixed in a close contact state with almost no gap, a stable adhesive force can be obtained. During the actual construction, after fixing the boundary block (5) and completing the construction, especially on the boundary block (5) that is on a business trip, on the peripheral surface of the joint plate body (1) within the range visible from the roadway. Paints with glass beads or luminescent coating are applied so that pedestrians and drivers stopping cars can notice the curbs and boundaries at a glance even at night.

[Effect of device]

 The present invention has the following effects by being configured in this way.

As described in claim 1, a groove hole (2) is formed in one end surface (11) of the joint plate body (1) and a filling hole (3) is formed, and the other end surface (12) is formed. By providing the adhesive layer (4), the other end face (12) side of the joint plate body (1) is fitted to the outer shape of the boundary block (5) from the beginning so that one connecting surface (51) of the boundary block (5) is located. Since it can be attached to the boundary blocks (5), when the boundary blocks (5) are arranged, a close contact state can be secured between the joint block body (1) and the boundary block (5) from the beginning. Since the work of finely adjusting the gap between the boundary blocks (5) is unnecessary and the work of adjusting the displacement of the joint plate body (1) is not necessary, the product of the present invention only needs to arrange the boundary blocks (5). Anyone can easily perform the work and save time and effort. Therefore, it can contribute to speeding up the construction work and reducing the design price. Further, since the boundary block (5) and the joint plate main body (1) are bonded and fixed in a close contact state with almost no gap, a stable adhesive force can be obtained.

Since the joint plate main body (1) is formed of a rubber plate or a rubber-based foam as described in claim 2, the joint plate main body (1) inserted between the boundary blocks (5) is Even if the boundary block (5) expands or contracts due to changes in climatic conditions, the joint plate body (1) has elasticity so that it can be sufficiently followed for a long period of time. It is possible to ensure airtightness across.

As described in claim 3, the joint plate body (1) is molded by solidifying a crushed product of a rubber plate or a foam with a synthetic resin or the like, thereby providing good wear resistance and weather resistance. Since the rubber plate or the crushed product of the foam can be used as industrial waste, it can contribute to the effective use of resources.

When the adhesive layer (4) comprising the adhesive (41) and the release paper (42) is used as in claim 4, the other end surface (12) side of the joint plate body (1) is previously attached. It can be attached to one of the connecting surfaces (51), (52) of the boundary block (5) and the construction of the boundary block (5) can be simplified.

If a double-sided sheet is used as the adhesive layer (4) as described in claim 5, it can be easily attached to the joint plate body (1) and the workability becomes extremely good.

As described in claim 6, the filling groove (3 ′) is formed from above the one end surface (11) of the joint plate main body (1) to near the center of the groove hole (2). 3 ') is easier to form than the filling hole (3), and the adhesive flows straight from the filling groove (3') into the groove (2), so that the bonding work can be performed faster. In addition, even if a large amount of adhesive is poured, it can be filled by flowing out from the side of the filling groove (3 ') inside the slot (2), so that the bonding work can be done faster and the filling is also reliable. It will be something that can be done.
