Description

  TECHNICAL FIELD The present invention relates to a floor slab form for a side groove cover, a floor slab for a side groove cover, and a method for forming a floor slab for a side groove cover.

Conventionally, there are various sizes of side grooves, and their uses are also various, and small ones are provided for drainage of rainwater on the side edges of roads and passages. There are water channels used for agriculture, water channels as part of natural water rivers, or factory waste water channels for domestic wastewater that has been purified.
Of the side grooves, the side grooves provided at the side edges of the roads and passages are usually provided with lids to ensure safety, and the side units of the side grooves have small units. So, when using a lid constructed by simply injecting only concrete into an appropriate formwork, or after placing several reinforcing bars in the appropriate formwork, the concrete is appropriately placed The lid formed by pouring into the mold is used.

On the other hand, in the side gutter used as the above-mentioned water channel having a larger scale than the side gutter provided on the side edge of the road or passage, a person or a vehicle etc. crosses the gutter at a specific place. For this purpose, it is a common practice to form a small-scale bridge by laying an appropriate plate-like body in such a manner as to partially cover the side groove.
A small bridge-like structure that partially covers such a gutter may pass a vehicle, such as an automobile, as part of the road. It is weak in strength and does not function as a normal bridge.
Therefore, in order to obtain a predetermined strength as a part of the side gutter lid that functions as a part of the road, that is, a small bridge, a side gutter having an appropriate reinforcing bar or reinforcing steel inserted in the concrete. A lid is often used.

  By the way, conventionally, when installing a lid for a side groove that also serves as a passage or a road in a predetermined side groove, a predetermined scaffold or a support is usually assembled in the side groove, and then a wooden product is assembled thereon. After forming an appropriate formwork using materials, after placing an appropriate number of rebars in a lattice form in the wooden formwork, pouring concrete into the formwork and curing the concrete, By removing the wooden formwork and simultaneously removing the scaffold or supporting work, a passage that also serves as a passage or road on a predetermined gutter is completed.

  However, in such a conventional construction method, the work process is complicated and the construction period is long, and furthermore, the installation of the scaffold or the support work and the dismantling work are dangerous. It was the cause.

  Furthermore, when there is a three-dimensional change in the surface shape of the side groove, that is, the topography in the vicinity of the side groove, for example, when the width of the side groove is changed, or the bank portion on one side of the side groove and If there is a step between the corresponding opposite bank, or the bank on one side is horizontal, the bank on the other side is not horizontal but inclined or up and down In the case where there are undulations, the method of forming the wooden formwork at a predetermined position using the scaffold or the support work makes the construction work more complicated and sometimes makes the construction impossible.

  Furthermore, in the prior art, it is assumed that the floor slab form for the side groove cover is formed on the scaffold or support, so that all the operations are performed at the site where the side groove cover is constructed. Therefore, in addition to requiring a lot of workers, it takes time to select the formwork and to install the formwork. However, it is necessary to accurately install the formwork, and at the same time to cut and bend the rebar. The work and the work of accurately placing and binding the reinforcing bars inside the formwork must also be performed at the site, so the work needs to be accurate and employ highly skilled workers. There is a problem that the necessity for the work is high and a long working time and labor are required, and the construction cost is increased due to frequent constructions and delays.

Furthermore, conventionally, after the concrete curing is completed, it is necessary to dismantle and remove all the formwork. Except for the parts to be reused, further work including the generation and transportation work of industrial waste This was an increase in time and cost.
As a method for solving such a conventional problem, as disclosed in, for example, JP-A-2004-285823 (Patent Document 1) or JP-A-2005-330809 (Patent Document 2), A reinforcing steel material having a plurality of hollow square cross sections in a direction orthogonal to the direction of water flow in the side groove, a reinforcing steel material having a U-shaped cross section, or a reinforcing steel material having an I-shaped cross section is closely connected There has been proposed a floor slab bridge that is arranged in parallel across the width of the side groove, and in which appropriate reinforcing bars or metal bars are arranged in a direction perpendicular to the reinforcing steel material, and concrete is injected into the reinforcing steel material.

  However, this method requires the installation of scaffolding or support works, and at the same time, the main gutter bridge is made of metal reinforcing steel, its usage is extremely large, and the usage of concrete is: Since it is only a small amount from the whole, not only is the manufacturing cost high, but it is necessary to cover the upper surface of the reinforcing steel material with a separate pavement material, which requires a further construction process, which naturally leads to an increase in cost. was there.

Japanese Patent Laying-Open No. 2005-299344 (Patent Document 3) discloses a structure of a side groove cover body in which concrete is placed by placing a reinforcing bar on the upper surface of a remaining mold frame portion as a cover body covering a large side groove. The feature is that a plurality of reinforcing ribs having a reverse taper section are formed on the upper surface of the residual mold part to prevent the residual mold part from being bent.
However, in the said patent document 3, while the said side groove cover body is formed in the construction site, the concrete arrangement | positioning form of a reinforcing bar, and the countermeasure with respect to the protection of the concrete of the side wall part of the said side groove cover body There is no disclosure or suggestion regarding.
