Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a construction method for constructing concrete-shaped ditches, L-shaped side ditches, etc.

[Problems to be solved by conventional technology and invention]

Conventionally, the method of laying this type of concrete trench, etc.
First, a concrete foundation is poured, and after it is hardened, mortar is poured on the top surface of the concrete foundation.The concrete groove is placed on top of the mortar while the mortar is not hardened, and the level etc. is adjusted. It was installed. As described above, the adjustment performed when the mortar is uncured is extremely laborious, takes a considerable amount of time, and is extremely difficult to perform. Therefore, a technical problem arises that needs to be solved in order to be able to perform operations such as level adjustment easily and to quickly lay the concrete trench.

[Means for Solving the Problems] This invention was proposed in view of the above-mentioned problems and as a solution to the above problems. Then, two rugs are arranged and glued at appropriate intervals on the upper surface of this foundation in the longitudinal direction, and then the upper surface of the foundation is filled with mortar and leveled to the height of the rugs. , to provide a method for laying concrete grooves, etc., characterized in that the concrete grooves, etc. are laid by placing and bonding the concrete grooves, etc. on the upper surface of the mat without the mortar drying. It is.

[Effect]

In this invention, two rugs having a certain height and width are adhered to the upper surface of a pre-cast concrete foundation at a predetermined interval in the longitudinal direction. In such cases, the mats will each have a certain height above the concrete foundation. Therefore, since the upper surface of the concrete foundation is poured to have a certain level in advance, when a concrete groove or L-shaped gutter is placed on the upper surface of the two strips of carpet glued to this upper surface, It is always placed at a certain level. Therefore, mortar is filled between the two mats glued to the top surface of the concrete foundation, and the mortar is leveled to the height of the mat before it hardens. If the release body of the adhesive on the upper surface is peeled off and the concrete groove etc. is placed on the upper surface of the rug, the concrete groove etc. will adhere well to the two rugs and will not press the rug. It sinks into the mortar, and as the mortar hardens, it is firmly laid on the concrete foundation. Therefore, the concrete trench etc. can be laid easily and quickly on the upper surface of the concrete foundation, which also contributes to cost reduction.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings. Figure 1 is a partially cutaway slope view showing the state in which a concrete trench is laid on the top surface of a concrete foundation. FIG. 2A is a partially cutaway slope view of the rug used in this construction method, and FIG. 2B is a sectional view taken along the line -A in FIG. In Figure 1, foundation 1 is poured with concrete. And this basic 1
The upper surface is previously formed horizontally for laying the concrete trench 2. Moreover, the rug 3 is shown in FIG. This rug 3 may be a long article having a certain height and width and generally having a rectangular cross section, but is not limited thereto. Furthermore, adhesive tapes 3a, 3a are adhered to the upper and lower surfaces of this rug 3, and release bodies 3 are attached to the outer surfaces of the rug 3, respectively.
b and 3b are attached. That is, this mold release body 3
b, 3b can be easily peeled off from the adhesive tapes 3a, 3a, and after peeling off, the adhesive tapes 3a,
It goes without saying that 3a can be easily adhered to other objects. However, this rug 3 may be made of a hard and elastic material. Further, although FIG. 3 shows a concrete L-shaped side gutter 4, the present invention can be applied to the concrete L-shaped side gutter 4 and others in addition to the concrete gutter 2.

As mentioned above, after the foundation 1 is poured with concrete and its upper surface is made horizontal and hardened, two strips of mats 3, 3 are placed at a constant interval in the longitudinal direction of this foundation 1. Glue. That is, the mold release bodies 3b on one side of the mats 3, 3 are peeled off and adhered to the upper surface of the concrete foundation 1, respectively. Then, mortar 5 is filled between the two mats 3, 3. Thereafter, the mortar 5 is leveled to the height of the mats 3, 3. Then, the mold release bodies 3b on the upper surfaces of the mats 3, 3 are peeled off, and the concrete grooves 2, etc. are placed on the upper surfaces. At this time, since both sides of the bottom of the concrete groove 2 in the longitudinal direction are placed on the mats 3, 3, the concrete grooves 2, etc. are placed neatly with almost no need for level adjustment, and the mats 3 , 3, the concrete grooves 2, etc. are well bonded with the adhesive tapes 3a, 3a on the top surface, and are firmly connected to the concrete foundation 1 by the hardening of the mortar 5, and the concrete grooves 2, etc. This construction method can be carried out extremely quickly, easily and reliably.

〔Effect of the invention〕

As described in detail in the above-mentioned embodiment, in this invention, two strips of carpet are glued at a constant interval in the longitudinal direction of the top surface of a concrete foundation whose top surface is formed horizontally in advance, so mortar is filled between them. Furthermore, the height of the rug is leveled and smoothed, and the release body on the top surface of the rug is peeled off to expose the adhesive tape surface, and the concrete groove etc. are placed on this top surface. The concrete grooves, etc., which are supported on both sides in the longitudinal direction by two strips of carpet, sink slightly by pressing the mortar uniformly, and when the mortar hardens, they are integrally connected to the concrete foundation, and the concrete It is an invention that brings about various great effects, such as being able to lay grooves extremely easily, quickly and reliably, contributing to improved workability and cost reduction.
