Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for installing an elevated structure at the edge of a roadway.
Concerning the construction of overhang sidewalks to be constructed.

Traditionally, irrigation canals have been used to drain water or water during the day. li is h, road//) Edge f is to create a sidewalk, Ic is for irrigation canals and rice fields 31! Arrangements had to be made. However, a sidewalk with a structure like this is actually an irrigation canal! Fill the field 1χ
Since it requires a lot of time and expense, it also eliminates the need for irrigation canals.

As a method of constructing an irrigation canal, etc., by extending a sidewalk over the edge of an elevated road (roadway) that is higher than the surrounding area without burying it, there is a conventional method, such as the structure shown in Figure 1. That is, a substantially frame-shaped concrete ring foundation block person, the foundation professional, the concrete ring overhanging beam B placed and fixed on the upper surface of the foundation professional, and the overhanging beam B being the foundation professional, It is formed from anchor bolts C and D planted on the top surface of the person.

Then, to create the sidewalk E ((First, excavate the soil at the edge of the roadway F to form an excavated section G in the shape of a disconnection line.Next, create a foundation professional made of GIC conocret for this excavated section. A are placed in parallel along the roadway F, and then fresh concrete H is poured into the foundation concrete A (after solidifying in Step 7, several anchor bolts C and D are planted). .

Then, place the overhanging beam B on the top surface of the foundation block A, and then position the foundation block in the several bolt insertion holes previously provided at the base a of the overhanging beam B. The anchor bolt G after

D through the bolt insertion hole 1. Place mortar h inside J and harden. And this anchor Porto C, DV
By screwing the two parts together through the CPl metal, the overhanging beam B is fixed to one surface of the base plate and rim. The surface plate on one side of the overhanging crosspiece B is paved with soil and asphalt (K and L) that have been backfilled into the excavated area G to create a sidewalk E.

! -7 However, the above-mentioned conventional product shown in Fig. 1 is constructed by placing the foundation block A iC'4E concrete H and inserting the anchor bolts C and D into the core bolt insertion hole I.
Place the mortar h completely in J and let it harden. Then, by screwing together the anchor bolts C and D through the washers, the projecting beam B is fixed to one side of the base plate A. After removing the surface plate on one side of the stretched crosspiece B, the excavated part G is backfilled with asphalt and L is paved to create a sidewalk E.

However, in the above-mentioned intermediate product shown in Fig. 1, the anchor bolt CID is placed in the foundation block by placing the ready-mixed concrete H on the foundation block. The casting work Cc is time consuming, and the installation position of anchor bolts C and D must be measured, which takes time and effort.

The mounting position of D was uneven for each basic pro and RIA.

It also took time and effort to sequentially attach the projecting beams B to the E surfaces of the foundation blocks A that were arranged side by side along the roadway F. Therefore, this conventional product is the sidewalk El! There was a drawback that it took a long time to construct i-.

Moreover, in order to plant the overhanging beam B on the top surface of the basic pro, the anchor pole (pol) [,D
Because the installation position of the base plate varies depending on the frame, the gap between the projecting beams B and the one placed several hundred meters away from each other may differ between the inside (roadway) and the outside (sidewalk side). Due to the unevenness of the road, it was not possible to construct an IE Chichichi walkway along the road.

The present invention has been made in view of the points mentioned above,
The purpose of this is to make it possible to create a sidewalk in a narrow space in a short construction period, and to make sure that the distance between the overhanging crosspieces is the same as the one at hand and the one on the outside of the surface board. We would like to provide a professional overhang walkway that can be laid at uniform intervals without causing irregular intervals.

An embodiment of the present invention will be described below with reference to FIGS. 2I"J to 4.

As a means for placing and fixing the above-mentioned two wooden projecting crosspieces 7, 7 on one surface of the two wooden projecting crosspieces 7, several bolts 9 planted on one upper surface of the overhanging crosspieces 77 can be used, for example. After inserting the bolt into the bolt insertion hole 10 provided at the corresponding position on the surface plate 8, insert the washer 1. and fix it with nut 11. 12 is a cover formed on one side of the surface plate 8; 13 is a mounting hole provided in this cover 12;
The supports 15 are attached and serve by inserting the ends of the supports 15 of the guide fence 14 into the grooves and filling and solidifying concrete. 16 is a guide rail, and 1γ is its support.

One embodiment of the present invention has the structure as described in (T) below, and the laying method for the operation (F) will be explained below.

To construct the sidewalk 2, first, an excavated portion 3 having a cross-section with a cross-section is formed at the edge of the roadway 1.

Next (In order to create the sidewalk 2, first, the foundation blocks 4 are installed in the excavated section 3 with a cross-section shaped like a cross section on the edge of the roadway 1. Reinforcement is placed between the opposing leg parts 5 and 5 of the foundation pro 2 and 4, and then the main concrete 11 is continued into the gap between the opposing leg parts 5 and 5 of the foundation pro and the girder 4. The foundation plate 4 is fixed to the excavated portion 3 by pouring and hardening, and the overhanging crosspiece 1 formed on the north face of the foundation plate 4 is cantilevered on the edge of the city road 1. ,
To support.

The gap in the excavated portion 3 is roughly backfilled at t18.

Then, on the long side of the two overhanging crosspieces γ and 7 formed on the upper surface of the basic protrusion 4,
Fixed at 1.

The arrogance is to backfill the gap in the excavated part 3 with ±18 and surface plate 8.
A roadway 1 and a sidewalk 2 are created by laying and solidifying γ Sfumalt 19.20 on the -E side of the road.

埒らε・こ、Surface plate 8 r) -1! The lower end of the post 15 is inserted into the mounting hole 13 of the ground foundation 12 formed at il+, and conocrete is filled and solidified to erect the post 15 and form the guide fence 14.

Similarly, on the roadway 1 side, a guide rail 16 is formed by extending the pillars 17 through 11C. Note that (in the invention described in -), two projecting beams γ are provided on the north face of the base plate 4, but the invention is not limited to this, and several pieces may be provided.

As mentioned above, the present invention has a structure in which the side surface of the foundation block is opened by forming the upper surface (C overhanging crosspiece) of the concrete foundation block, so that the foundation block 2 is lighter. At the same time, it was installed parallel to the excavated part on the edge of the city road, and the foundation pro was firmly attached to the excavated part by simply pouring ready-mixed concrete continuously on the legage part facing the base pro. It is possible to create a sidewalk at the edge of the roadway by fixing it to the concrete surface and making use of the convenient slope.By pouring ready-mixed concrete continuously in this way, the foundation projector was established as a strong VC excavation area. Therefore, the tilting of the foundation block can be prevented from IE.

For this reason, unlike in the past, it took a lot of time and effort to pour raw conocrete inside the foundation block, solidify it, and then plant it in the anokur/gelt. Since the installation work is simplified, the construction period can be shortened and construction costs can be reduced.

As mentioned above, the overhanging pier is still formed on the top surface of the foundation block, so the foundation protrusions are installed side by side along the elevated roadway. The gap between the parts is uniform on the inside and outside, and it is exactly 1 step toward the city road.
6 can be created.
