BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a concrete gutter used for roads and the like integrally with a gutter cover, and a manufacturing form used for the same. More specifically, the present invention relates to a method for manufacturing a concrete gutter having a cover receiving elastic material embedded and fixed for preventing noise on a cover receiving surface of a main body, and a manufacturing form used therein. ＠

2. Description of the Related Art Conventionally, there has been provided a gutter cover on both ends of a back surface of a main body in which an elastic material is exposed to be buried and fixed. Since the elastic material is manufactured by a flat hitting method in which the elastic material is placed and pressed from above, there is a disadvantage that the depth at which the elastic material is embedded in the side groove cover is not constant. Therefore, the thickness of the entire gutter cover was not uniform, and the surface did not become flat even when used as a gutter cover on a road or the like. Therefore, concrete gutters in which an elastic material for lid receiving is embedded and fixed on the lid receiving surface have come to be used. As shown in FIGS. 8 and 9, this type of concrete gutter needs to embed a lid receiving elastic material in the lid receiving surface.
As shown in (2), it is common to manufacture the lid receiving elastic material on the lid receiving portion of the production form by placing a concrete on the lid receiving elastic material. The depth embedded in the side groove was constant. However, simply placing the elastic member on the lid receiving part of the manufacturing form frame causes the elastic member to be displaced when concrete is poured, or the concrete seeps from the side of the elastic member. As a result, when the gutter is completed, concrete adheres to the surface of the lid receiving elastic material, or it takes time to clean the production form. Therefore, recently, as shown in FIGS. 10 and 11, a cover receiving elastic material having a recess in the surface longitudinal direction is used, and a bar magnet is fitted into the recess of the elastic material, and the magnetic force of the bar magnet is used. A method has been devised in which the lid receiving elastic material is tightly fixed to the lid receiving portion of the production form, thereby preventing the lid receiving elastic material from being displaced and preventing concrete from seeping from its side. ＠

However, in the above-mentioned conventional method, there remains a problem that the operation of fitting the bar magnet to the lid receiving elastic member is complicated, and the formed side groove is removed by removing the formed side groove. Even if the bar magnet is to be removed from the lid receiving elastic material, there is still a problem that the bar magnet is tightened due to the contraction of the lid receiving elastic material due to the shrinkage of the concrete, so that it is difficult to remove the bar magnet. It had been. ＠The present invention was devised there, and the purpose of the invention is to easily attach the lid receiving elastic material,
In addition, the present invention provides a method for manufacturing a concrete gutter in which the cover receiving elastic material is not displaced when concrete is poured and the concrete does not seep from the side, and a manufacturing form used directly in this manufacturing method is provided. Is to do. ＠

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete gutter 20 according to the present invention will now be described.
An embodiment of the manufacturing method 100 and the concrete mold 100 for forming a gutter used in the method will be described with reference to FIGS. The production formwork 100 of the concrete gutter of the present invention is:
As shown in FIG. 1 and FIG. 2, it comprises a convex body 10 for forming an inner wall 40 of a concrete side groove 200 and the like, a pair of both side plates 20, and a pair of both end plates 30. ＠ The convex body 10 is the inner wall 40 of the concrete gutter 100.
And a lid receiving surface 41 of a concrete gutter 200 protruding to both sides from the inner wall portion 11.
And a lid receiving portion 12 for forming the same. A rectangular bar as a locking portion 13 is fixed in the longitudinal direction to the edge of the lid receiving portion 12 so as to lock one end of the lid receiving elastic member 70. The locking portion 13 may be a square bar perpendicular to the lid receiving portion 12 as shown in FIG. 3, but may be a tapered bar as shown in FIG. 13a or a locking portion 13b made of an inverted L-shaped bar as shown in FIG. 5, the lid receiving elastic member 70 is connected to the inner wall portion 11 and the locking portion 13a.
This is preferable because the lid receiving elastic member 70 is unlikely to come off when locked with the a and 13b. The lower ends of the side plates 20 are pivotally supported on both sides of the lower surface of the convex body 10, respectively, and are pivotally opened on both sides. The engagement protrusions 21 that fit into the engagement fittings 31 provided are provided on both upper sides of the side plate 20. And these two side plates 2
0 is a concrete gutter 2 as shown in FIGS.
When 00 becomes a product, it acts to form the outer wall 50. The lower end plate 30 is pivotally supported at both ends of the lower surface of the convex body 10 and pivots to open on both sides, and is provided on both upper sides of the side plate 20 when closed. The engagement metal fitting 31 for fitting the engagement projection 21 to the end plate 30
Are provided at both upper ends. And when these concrete side gutters 200 become a product, these both end plates 30
Acts to form end face 60. Each of the end plates 30 is provided with a fixing lever 32 for fixing the both side plates 20 and both end plates 30 when they are closed.製造 A method of manufacturing the gutter 200 using the concrete formwork 100 for gutters configured as described above will be described. First, as shown in FIG. 1, the fixing lever 32 is operated to operate the side plates 2 of the production formwork 100 of the concrete gutter.
0 and both end plates 30 are opened. Next, the lid receiving elastic member 70 is engaged with the lid receiving portion 12. First, one end of the lid receiving elastic member 70 is locked to the locking portion 13. Then, the other end is fitted into the inner wall portion 11. In this manner, the lid receiving elastic members 70 are sequentially fitted in the longitudinal direction, and the lid receiving elastic members 70 are locked by the locking portions 13 and the inner wall portion 11.
The lid receiving elastic member 70 is engaged with the lid receiving section 12. Next, the both side plates 20 and both side plates 30 are closed, and the fixing lever 32 is operated to be firmly fixed. By the above operation, the preparation work of the production formwork 100 for the concrete gutter is completed. In this state, the concrete is poured from above while applying vibration, and the raised unnecessary concrete is removed with an iron to finish the upper surface. Then, it is left for a while while heating and drying until the concrete solidifies. Next, when the concrete has solidified, the concrete is released. The fixing lever 32 is operated to open both side plates 20 and both end plates 30. Thereafter, the end face 60 of the formed concrete gutter 200 is locked by a crane or the like, pulled up, and removed from the mold. By the above operation, the concrete side groove 2 in which the lid receiving elastic member 70 is embedded and fixed in the longitudinal direction.
00 can be manufactured. It is preferable to use a soft rubber material such as vinyl chloride as the lid receiving elastic member 70 in that the operation of fitting the other end of the lid receiving elastic member 70 to the inner wall portion 11 is easy.
Further, as the lid receiving elastic member 70 to be used, the same lid receiving elastic member 70 used in the conventional example shown in FIG. 12 can be used. This is the lid receiving elastic material 7
This is because, since the material 0 is made of a soft rubber material or the like, it has an advantage of being easily curved, and can be fitted between the locking portion 13 and the inner wall portion 11. ＠On the other hand, vinyl chloride or the like used for the lid receiving elastic member 70 has a drawback that processing accuracy is not good and it is difficult to finish the lid receiving elastic member 70 with a constant width. Therefore, if the lid receiving elastic member 70 having the contractible bulging portion 72 as shown in FIGS. 6 and 7 is used, even if the dimensional accuracy slightly varies, the locking portion 13 and the inner wall portion 11 can be connected. It can fit properly between. ＠

As described in detail above, according to the present invention,
The reverse tapered engaging portion is provided in the cover receiving portion of the convex body, a lid receiving
One end of the elastic member is locked to the locking portion, and the other end is fixed to the inner wall.
