Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable to facilities for track and field events and ball games, golf courses,
Regarding elastic pavement structures that are ideal for small paths or jogging courses, etc., in particular, we need a construction method that can easily treat the end portions of such elastic pavement materials, and a curb structure that is optimal for this construction method. Regarding.

[Conventional technology]

Natural grass and dirt are being considered as surfaces for outdoor stadiums, however, these are difficult to maintain. Therefore, elastic pavement structures have been provided that use small lumps or granules of rubber, cork, elastic synthetic resin, etc., and use a cushion layer made of these combined with a binder resin, or that are made of urethane resin alone. Ru.

An example of such a conventional elastic pavement structure is explained with reference to FIG. 3. An elastic pavement material is constructed by applying and curing a fluid such as urethane resin on a base l made of asphalt, concrete, etc. 2 facilities. The end portion of such elastic paving material 2 is constructed as follows. That is, first, the curb 3 is installed adjacent to the base 1 so that the upper surface of the base 1 and the upper surface thereof are at a uniform level. Next, a formwork board 4 is placed on the side of the curb 3 opposite to the extending direction of the elastic paving material 2 with a predetermined gap so that the end portion of the elastic paving material 2 hangs downward. A back-up material 5 made of foam material or the like is temporarily fixed to the lower part of the board 4 and the side surface of the curb 3 to define a gap with the curb 3. Finally, to prevent the fluid elastic paving material 2 from flowing down, a stone, soil, contour block, etc. is placed on the surface of the board 4 opposite to the bank-up material 5 so that the back-up material 5 is pressed closely against the curb 3. A pressing member 6 is provided. The fluid elastic paving material 2 is poured into the gap between the curb stone 3 and the board 4 thus framed, and when it hardens, the pressing member 6 and the board 4 are removed.

It should be noted that the elastic paving material 2 above the curb 3 is located at a corner of the facility and will not be used as a direct competition or playground, so it does not need to be very thick. Therefore, two layers of elastic paving material are used, and the upper surface of the lower layer of elastic paving material is installed at the same level as the upper surface of the curb 3, and the upper layer of elastic paving material is installed on top of the lower layer of elastic paving material. ing.

[Problem to be solved by the invention]

However, in both construction methods, the formwork board and backup material are pressed against the curb using a pressing member, which is an unstable condition, and the thickness of the depressed part of the elastic paving material becomes unstable. Instead, a gap may form between the backup material and the curb, and if such a gap occurs, the liquid resilient paving material will flow out.

In addition, in the latter case, the foundation must be lowered from the top surface of the curb by the thickness of the lower layer elastic paving material, making it difficult to install the foundation and causing unevenness6.Therefore, near the curb, the upper layer elastic The thickness of the paving material is being adjusted while pouring.

Therefore, an object of the present invention is to provide a method for constructing an end section of an elastic paving material by making simple improvements to the curb stone, and to provide a curb stone that is easy to perform end treatment. It is to be.

[Means to solve the problem]

The terminal construction method of the elastic pavement structure of the present invention is to provide a base so that its top surface is located at approximately the same level as the top surface of a curb having a step at its upper corner, and The surfaces of the board members for the formwork are temporarily fixed, and a fluid elastic paving material is applied to the desired thickness on the top surface of the foundation and curb, and the elastic paving material is applied to the gaps between the steps framed by the board members. After pouring the material and curing the elastic paving material,
The feature is that the punched member is removed from the curb.

This invention also provides a curb for fixing an end portion of an elastic pavement structure in which an elastic pavement material is provided to a predetermined thickness on a base.
A curb stone is provided at the upper corner of the side opposite to the extending direction of the elastic paving material, and has a stepped portion for dropping the end portion of the elastic paving material.

This curb stone also has another step at the upper corner facing in the direction of extension of the elastic paving material, and the bottom surface of this another step defines the top surface of the base.

[For production]

Since the base only needs to be installed so that its top surface is located at approximately the same level as the top surface of the curb, it is possible to easily level the base. Since the plate member for the formwork can be temporarily fixed to the side surface of the curb in surface contact, the plate member will not be peeled off from the curb when the elastic paving material is poured.

therefore.

The elastic paving material is poured into the gap between the steps of the curb framed by the board members, and after the elastic paving material has hardened, the end part of the elastic paving material can be reliably attached to the curb by simply removing the board members from the curb. It can be dropped to a predetermined thickness and fixed.

In addition, the curb can be securely fixed because the plate-shaped member for the formwork can be fixed to the side surface in surface contact, and the end of the elastic paving material can be placed in the gap formed by the step between the plate-shaped member and the curb. can be dropped and fixed. Since the leveling of the foundation can be done using a part of the curbstone, the leveling of the foundation can also be done easily.

Furthermore, if another step is provided on the curb, when the elastic paving material is composed of two layers (upper and lower), the thickness of the lower layer elastic paving material can be set at this separate step, so two layers can be set. Structural elastic paving materials can be easily constructed.

〔Example〕

Hereinafter, embodiments of the present invention shown in the drawings will be described.

The same reference numerals are given to the same components throughout each embodiment, and detailed explanation thereof will be omitted.

First, a first embodiment will be explained with reference to FIG. 1. A curb 12 that fixes the end portion of an elastic paving material 11 similar to the above-mentioned elastic paving material 2 has a base 13 whose upper surface is made of asphalt, concrete, etc. installed at a level with the top surface of the A plate-like member 14 for formwork is temporarily fixed to the surface of the curbstone 12 facing the base 13 with an adhesive material 15 such as double-sided adhesive tape.

The plate-like member 14 is made of a synthetic resin such as polyethylene or polypropylene that has good releasability from the elastic paving material 11, or a wooden board with adhesive tape or the like attached to the surface. At the corner of the curb 12 on the side of the plate member 14, a stepped portion 16 is formed into which the end portion of the elastic paving material 1 is dropped and fixed. The elastic paving material 11 is poured into the gap formed by the plate member 14 and the stepped portion 16, and after hardening, the plate member 14 is peeled off from the curb 12, and the construction of the end portion is completed.

Based like this! 113 can be installed at the same level as the top surface of the curb 12, so the installation of the base 13 is extremely easy, and the plate member 14 can be fixed to the side of the curb 12 in surface contact, so it can be securely temporarily fixed. It can be fixed, and the pressing member 6 unlike the conventional one is not required. Further, since the step portion 16 for dropping is formed on the curb 12, the lowering of the end portion of the elastic paving material 11 can be carried out simply by pouring.

A second embodiment shown in FIG. 2 shows a case where the elastic paving material is composed of an upper layer elastic paving material 21 and a lower layer elastic paving material 22. The upper layer elastic pavement material 2I is composed of a cushion layer made of, for example, urethane resin, which has excellent durability and weather resistance.
The lower layer elastic paving material 22 is made of rubber or cork chips bonded to the upper layer elastic paving material 21 via a primer or the like.
It consists of a cushion layer consisting mainly of lumps or granules, which are bonded together with a binder resin. Curb 12
The lower layer elastic paving material 22 is placed at the corner opposite to the step 16.
A step portion 23 is formed for this purpose. The upper surface of the base 13 is constructed so as to be at the same level as the stepped portion 23.

In this second embodiment, the top level of the base 13 is
It is only necessary to construct the paving material so that it is at the same level as the stepped portion 23, and the lower elastic paving material 22 can be easily constructed because it is sufficient to cast the lower layer elastic paving material 22 on the base 13 up to the level of the upper surface of the curb stone 12. Additionally, the upper layer elastic paving material 21 may be cast to a desired thickness on the upper surface of the lower layer elastic paving material 22 and the curbstone 12.
Only the upper layer elastic paving material 21 is located on the upper surface of the stone I2, and the end portion of the upper layer elastic paving material 21 is located between the stepped portion 16 and the plate member 14.
It can be securely fixed in between.

It goes without saying that the configurations of the upper elastic paving material 21 and the lower elastic paving material 22 in the second embodiment may be reversed.

〔Effect of the invention〕

The terminal construction method of the elastic pavement structure of the present invention is to provide a base so that its upper surface is located at the level between the upper surface of a curb having a step at its upper corner and the side surface of the curb having a step. Temporarily fix the surface of the board member for the formwork to the top surface of the foundation and curb, and apply a fluid elastic paving material to the desired thickness on the top surface of the foundation and curb. After pouring the paving material and curing the elastic paving material,
Since the end portion of the elastic pavement structure can be reliably fixed to the curb through the simple process of removing the plate member from the curb, the end treatment becomes extremely easy.

Further, in the curb of the present invention, a plate member for formwork is fixed along the extending direction of the curb on the side surface opposite to the extending direction of the elastic paving material of the curb into which the end portion of the elastic paving material is dropped, Since a step part for wrapping the elastic paving material is formed at the upper corner of the plate-shaped member, the plate-shaped member can be securely fixed to the side surface of the curb in surface contact, and the step between the plate-shaped member and the curb can be fixed. The end part of the elastic paving material can be dropped into the gap formed by the part and fixed. Therefore, it is possible to prevent the elastic paving material from peeling off from the curb due to thermal contraction or expansion. Furthermore, since the foundation can be leveled using a part of the curbstone, the foundation can be easily leveled. Furthermore, if another stepped part is provided on the curb, 1
When the elastic pavement system is composed of upper and lower two layers, the thickness of the lower layer elastic paving material can be set at this separate step part, so that the two-layer structured elastic paving material can be easily constructed.
