Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a long car stop block used at the boundary between a sidewalk and a roadway, which relates to a product that is easy and safe in manufacturing, and safe and quick in construction. is there.

[0002]

[Prior art]

 The most commonly used conventional product is a product with a length of 60 cm according to the Japanese Industrial Standards Concrete Border Block (JIS-A-5307), but the closest product is a product with a length of 2 m. Has also come to be used.

The manufacturing method of these products is as follows: For products of 60 cm of Japanese Industrial Standard, concrete is placed from the bottom of the product, at the time of finishing, at least two lifting bar reinforcements are buried and they are lifted and removed at the time of demolding. Since the product is 60 cm in length or is to be molded, it was demolded using scissors.

When the length of the product becomes 2 m, the scissors removing tool cannot be used, and the lifting bar of 2 to 4 is exclusively buried in the bottom part (concrete pouring surface) and demolded.

At the time of construction of the product, in the case of a product of 60 cm of Japanese Industrial Standard, the product is lifted by sandwiching both sides with a number wire, and when the product is 2 m long, an opening is provided and the product is lifted through a wire. It was constructed.

[0006] However, these products and construction methods have the following disadvantages and problems.

[0007] First, at the construction site, since the product in the state of manufacturing is inverted and constructed on a horizontal basic concrete, there was a drawback that the hanging bar reinforcing bar at the time of manufacturing demolding was an obstacle. However, in order to eliminate this condition, a groove is constructed so that the lifting bar can be bent at the time of construction, but it is often difficult to finish and it is necessary to smooth the bottom of hardened concrete during construction, which is very difficult. I was forced to spend time and effort.

[0008] Considering these drawbacks, it is dangerous to use scissors-removing metal fittings at the time of demolding without using the hanging bar rebar, and at the same time, both sides were sandwiched by the number lines at the time of construction. , There was always the danger of slipping.

[0009] Even if the product is a 2m product, the use of the lifting bar had the drawbacks of the above-mentioned instructions. Even if the product has an opening and is lifted through a wire, the lifting bar at the time of demolding is necessary and the above-mentioned instructions are given. However, when the wire was pulled out after the construction was completed, the end of the wire (hook) could get caught in the opening and move the product. Therefore, if the opening was enlarged to compensate for this defect, it could not be made at all because the opening was exposed from the pavement surface.

Therefore, the inventors of the present invention have been engaged in the manufacture and construction of these products for a long time, and have solved the problems of the present invention as follows.

[0011]

[Problems to be solved by the invention] The formwork does not require any special cost and the materials used are inexpensive. It should be safe and easy to manufacture and to perform safe and easy work even when demolding. It should be possible to safely and swiftly perform product reversal, hoisting during construction, and subtle setting adjustments. It should be possible to prevent products that have been carefully constructed from being pushed and moved due to rolling pressure on the road surface. In addition, make the devised technology available for manufacturing and construction of other environmental products.

Based on the above problems, the solution means of the present invention is as follows.

[0013]

[Means for Solving the Invention] Penetration through two important points on both sides of the form of a long product that is cast from the lower part to the concrete. , The attachment form will be further provided with an opening for accommodating the rebar bar, so that the product can be manufactured by placing it as a rebar of a length that can be flexibly used and placing concrete.

This will be described sequentially with reference to the drawings of the embodiments.

[0015]

【Example】

 The embodiment [FIG. 1] is a perspective view showing the outline of a typical product according to the present invention and a detailed view of the main parts. First of all, the bottom part that comes into contact with the foundation concrete during construction is the concrete placing surface 1. The product has a length of L = 2 m or more, and has a long formwork structure. The joint joint filling section 2.2. Are provided, and two recesses are formed on both sides of the bottom surface through the recesses 3.3. It was designed as an attachment formwork (open formwork of a size that is not exposed on the pavement surface), and two parts were bent at one location of this attachment formwork so that it would protrude by at least 50 mm or more from the product width. Bendable rebar rebar 4-1.4-2.4-3.4-4. A long pedestrian road boundary block B. It is.

The drawings of the examples are all Katamaru (a product of a site where one side in the extension direction of the top is a chamfered product and the sidewalk is higher than the road), but both circles (the height of the road and the sidewalk are the same. (Products on site) All the products are the same except that the joint filling part is formed on the entire surface of the end except the ground contact surface.

The embodiment [FIG. 3] is a schematic perspective view of the product of the embodiment of [claim 2], and the drainage opening 5. And a generator that can be freely extracted in cooperation with this 6. Generator opening part 6-1. Same as the product of [Claim 1] of the above instruction, except that the special attachment form is used for manufacturing (the drawing is in the center, but you can move the attachment to change the construction position). Since this is the case, the description is omitted.

[FIG. 4], [FIG. 5] and [FIG. 6] are environmental long pedestrian road boundary blocks B. It is a perspective view of an example product, and the surface of the mold is a decorative surface as an environmental product. 1 is the same as the product shown in FIG. 1 and the description thereof is omitted.

7 to 8 are pedestrian road boundary blocks B. Is made into a long product, and a recess is planted at the top of the product. Or, a convex planting BOX7. And build a flower 8. Since the planting method is the same as that of the product shown in [Fig. 1], its description is omitted.

The present invention constructed as described above has the following actions and effects.

[0021]

[Effects and effects of the invention] Regardless of whether the product is a single-circle product shown in the drawing or a double-circle product not shown in the drawings, a conventional standard formwork is provided with an attachment formwork with a through hole for the recess. Since it is only necessary to provide an opening for insertion of the lifting bar reinforcement, no special cost is required and the materials used are inexpensive.

For manufacturing, just insert a long rebar (a length that can be bent from a demolding hook and attached to the asphalt after installation) by inserting a long rebar into the attachment form of the through hole of the recess. There is no need for finishing, and there is no need to dig a groove for bending the reinforcing bar as in the past, or to cut this reinforcing bar after finishing and demolding, and at the same time, demolding work can be performed safely and easily [Fig. 2- 1] You can.

In addition to product reversal and lifting during construction [Fig. 2-2], the work is safe and easy because it is a four-point suspension by bending the reinforcing bar from the demolded state. As for the subtle front and rear or high and low setting adjust of [3], lift the front two or rear two or one place and use the lever bar in the recess penetrating hole 9. By moving the front and back, the delicate work can be done quickly and easily, and when the work is finished and the asphalt pavement is completed, the asphalt can enter the recessed holes and fix the product.

In addition, in the conventional product, the set adjust may be so small that the product constructed with a great deal of work may be pushed and moved by the rolling force of the machine when the wire is pulled out or when the road surface is paved. Then, the reinforce bar after construction is buried in pavement asphalt at an appropriate angle and height [Fig. 2-4] by bending and placing it so that the product is pressed by the rolling pressure of the road paving machine. There is no movement.

In addition, the technology of the present invention can be applied to the environmental products of the embodiments of [FIG. 4], [FIG. 5] and [FIG. 6].
