JP3004656U - Variable side groove with a fitting slide lid configuration - Google Patents

Abstract

(57) [Summary] (Modified) [Purpose] In the variable gutters for roads, it is possible to safely open the concrete lid during cleaning inspection without removing the concrete lid, and at the same time, the contact angle of the concrete lid is missing due to the handling of the product. Providing products that eliminate the problem. [Structure] The lid of the variable gutter is configured with a concrete lid 4 on both sides and a grating lid 5 in the center, and the lid abutment 3 is provided.
A groove or hole is provided in the cover to remove the grating lid when the lid is opened, pull up the concrete lids on both sides, and lean over the both culverts to stand up.The grating lid or pins are used to prevent the concrete lid from falling. It is a variable side groove of the fitting slide lid.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combination structure of lids in a gate-type variable gutter having a top-end ditch on both side walls.

[0002]

[Prior art]

 The conventional variable gutter has double gables at the top end, and has the following problems and drawbacks due to the combination of two concrete lids or one grating at the opening.

Two concrete lids are heavy. The one-plate grating had a drainage effect, but the pedestrian had a large discomfort at the opening, and the two concrete lids had a poor drainage effect. Removal was difficult and dangerous at the time of cleaning and inspection, including when fitting the lid. Since there is no construction clearance when removing the lid and refitting it on the abutment, the products often had corner cuts due to the contact between the lids or the lid of the main body.

Therefore, the applicant of the present invention has made the product of the present invention as follows while engaging in the manufacture and construction of these products.

[0005]

[Problem to be Solved by the Invention] By using a small lid and combining it with a small grating in the center, the concrete lid is made lighter than before, and at the same time, the cost of the entire product is reduced. Both sides are made of concrete lid and the center is made of grating to improve the drainage effect and facilitate the work. For maintenance of cleaning and inspection, the lid will be removed from the main unit and it will not be moved as before. While eliminating the danger of removing and moving work, it is possible to prevent the corners of the main body or lid from coming into contact with each other when handling and contacting each other.

The solution means of the present invention is as follows in consideration of the above problem to be solved.

[0007]

[Means to be solved by the device]

 Variable side gutters Main body lids are concrete lids on both sides, and a small grating lid is used in the center.In the case of an opening for maintenance, use a lid support abutment of the main body to put heavy concrete on both sides. Slide the lid, stand it up without removing it, and fix it with gratings or pins to prevent the lid from tipping over. This will be sequentially described with reference to the drawings of the embodiments.

[Example of device]

 Both soil retaining side walls 1.1. And a ridge end 2.2. Although not shown in the figure as an integrated gate type, the bottom slab is placed with invert concrete to form a water channel, and in the variable gutters that form a water channel, a lid fitting abutment is provided on the inner surfaces of the top ends on both sides 3.3. Is installed, and its abutment 3.3. At the end of the groove (at a position where clearance 2 to 3 mm is provided in the width of the concrete cover thickness t.) 9.7. Are installed opposite to each other.

This abutment 3.3. Use both sides with concrete lids 4.4. Lid thickness t. It is installed and fitted as a product shortened by 1/2 or more.

At the center thereof, a grating lid 5.5. Having a width of a lid thickness t / 2 or more. Concrete cover 4.4. Similarly, it is fitted and provided.

Grating lid 5. Fig.4 shows the case of one sheet. As shown in the cross-sectional drawing of the product in Figure 7, the lid falls prevention bottle hole 7-7-1. And

With the configuration of the product of the present invention, the opening of the lid during cleaning and inspection management, which has been difficult in the past, is performed by the following procedure.

First, the central grating 5.5. Which can be removed relatively easily. The heavy concrete lids on both sides 4.4. To the thickness of the lid 5.5. Slide to the space removed from the top, and the apex abutments on both sides 2.2. Stand up in the direction.

Next, the previously removed grating 5.5. Abutment 3.3. Grating Groove 7.7. (When there is one grating in the center, this grating drop groove 7.7. Is a hole groove 7-1.7-1. Into which a steel retaining pin or a metal fitting can be fitted).

The product of the present invention thus constructed has the following actions and effects.

[0016]

[Operation and effect of the device] The structure of the lid is lighter than that of the conventional product due to the combination of the two concrete lids on both sides and the grating lid in the center. A draining effect is good because the center has a grating lid. Once the lid is fitted and installed, it can be guided without being removed from the abutment during cleaning and inspection management, and the work can be done easily and safely without danger. There is no risk of contact between the lids or the product contact angle with the main body during installation. In addition, the grating grooving groove that prevents the lid from falling when the lid is raised also serves as an opening for the abutment in the lower part of the concrete lid to enhance the drainage effect. As described above, the non-removable variable side groove of the present invention has greater safety and at the same time an economical effect as compared with the conventional products.
