Description

  It relates to the protection of pedestrians during road occupations in construction and road construction.

  Conventionally, in the case of road occupation in building construction and road construction, methods for protecting pedestrians have been division of temporary walkways by Color Cone (registered trademark) and guidance by traffic guides. For this reason, pedestrians were to pass by cars and heavy equipment in the work site.

  However, in the case of a car colliding with a temporary lane division by Color Cone (registered trademark) or guidance by a traffic guide or when a heavy construction machine hits, it is almost meaningless from the viewpoint of pedestrian protection. In addition, when an opponent comes, it will protrude from the roadway side and the construction site, increasing the risk that the pedestrian will come into contact with the vehicle and heavy equipment for construction.

  As an improvement measure, there is also a method of dividing the mesh fence by setting it at the boundary between the temporary walkway and the roadway. However, the mesh fence is fixed with a circular block and the mesh fences are tied with a string or a wire, and a single pipe is used. Otherwise, there was a risk of collapse due to strong winds. There is also a method of separating the temporary walkway and the roadway with a product with a guard rail attached to the H steel installed with the web facing upward, but the hole-in anchor is set to asphalt during installation so that the H steel does not shift due to a car crash or the like. It was necessary to drive in and bolt it down, and at the time of removal, the asphalt was damaged because it thundered or gas cut the hole-in anchor. Since the unit weight of H steel used with it is as light as 100 kg to 135 kg per meter, there was a drawback that the H steel was greatly shifted in a car crash.

  In addition, there is a method to divide the construction site from the temporary walkway by a universal pot, but the material is weak, so if a construction heavy machine collides, the universal pot is damaged, and the pedestrian may be put at risk. Due to structural problems, the universal wall is driven by a single pipe, and the construction site side is set aside, so the construction site side becomes narrower than the universal wall with a width of 1 m or more. In addition, there was a large possibility of collapsing to the sidewalk side in the case of strong winds due to the lack of driving length of single pipes that were driven on the side of the front side.

  In terms of costs, the conventional temporary walkway method requires one traffic director at each end for traffic control, and it is necessary to arrange a traffic director in the middle as the distance increases. Even when heavy equipment for construction works near a temporary walkway, it is necessary to arrange a supervisor and a traffic guide, which increases construction costs.

The present invention solves these problems, sidewalk step receiving side is formed in one direction at one end against, a sidewalk concrete plate stepped restrained side is formed at the other end, another intersecting the one direction A concrete plate for sidewalks, characterized in that a concave groove is formed near one end in the direction and a rectangular opening or a concave groove is formed near a pair in another direction. It is used as an integrated sidewalk.

By applying an inverted T-shaped cutting to the concave groove bottom described in (0007) above , the guard pipe or the fall prevention fence is used as a structure that can be slid and inserted along the inverted T-shaped cutting.

  As shown in FIGS. 1 and 5, H steel is built in a rectangular opening provided in the upper part of the concrete plate for sidewalk at one end in the other direction intersecting with one direction described in (0007), and the flange of the H steel and the flange Insert a soundproof panel between them.

  A guard pipe or fall prevention fence is installed at one end or both ends by inserting and installing strut hardware in a concave groove provided in the upper part of the concrete plate for sidewalks at one end or both ends in one direction intersecting one direction described in (0007) above. It is used as a structure that can be installed.

  A structure in which curbstones can be inserted and installed at one end or both ends by providing a concave groove provided in the upper part of the concrete plate for sidewalks at one end or both ends in another direction intersecting one direction described in (0007) above. Used as

  In the present invention, for example, as shown in the embodiment, a step of about 20 cm to 40 cm is provided on the roadway and the sidewalk to give a car stop effect, and the weight of the concrete plate for sidewalk is set to, for example, about 1300 kg per sheet and overlapped. To make it difficult to slip even if a car crashes.

  By installing the guard pipe shown in the above (0009), it is possible to prevent a pedestrian from protruding onto the roadway.

  Protecting pedestrians from sound and scattered objects at the construction site while protecting the pedestrian by separating the construction site from the sidewalk by installing the panel with the rigidity and soundproofing effect of H steel shown in (0008) above To do.

  Since the sidewalk is easily established with the above configuration, it is not necessary to arrange traffic directors or surveillance personnel, and installation and removal can be performed without damaging asphalt. In addition, since the concrete plate for sidewalks is a single unit combination, partial repair is possible even if it is damaged. Therefore, even when the sidewalk rises or sinks due to an earthquake or the like, it can be restored early by partial repair, and the construction period can be shortened. In addition, the concrete plate for the sidewalk itself is a single product that can be diverted because it is a concrete product that is not easily crushed. This eliminates the need for industrial waste treatment of asphalt, concrete, and secondary concrete products on the sidewalks that were disposed of as industrial waste in the conventional construction method, contributing to reductions in industrial waste emissions, construction costs, and environmental aspects. sell.

  Hereinafter, an example of a concrete version for sidewalk will be described with reference to the drawings. The concrete plate 3 for sidewalk shown in FIG. 1 is installed on asphalt or on the ground after unevenness correction. Since there is some uneven surface on the asphalt or the ground after unevenness adjustment, the adhesion between the ground and the concrete plate 3 for the sidewalk is spread with 2-3 cm of sand or a mixture of sand and empty mortar and sand. By increasing, the uneven settlement is suppressed by the overall load.

  2 is hung on a suspension ring 5 integrated with the sidewalk concrete plate 3 shown in FIG. 3 in a circular opening 4 opened at both ends intersecting the sidewalk concrete plate 3 in one direction. Install it at the planned position with a crane. At this time, the opening 6 side for building the soundproof panel column is set on the construction site side, and the concave column metal slide groove 8 side is set on the roadway side.

  The use of the sidewalk is made by integrating the sidewalk concrete slab 3 by using the stepped side 14 on one side in one direction shown in FIG. Install the parts. By installing this concrete plate 3 for sidewalks, a step of 20 cm to 40 cm as a substitute for a car stop is born and protects the pedestrian from the car. Also, even if the car crashes, if the weight of the concrete plate for sidewalk is preferably about 1300kg per piece, it will be the same weight as a passenger car, and the overlapping structure will add many times the weight, so it will shift It becomes difficult.

  The tip of the soundproof panel support 1 is lifted with a crane and installed in the vertical direction in the opening 6 for building the soundproof panel support shown in FIG.

  By pressing the inner walls of the soundproof panel support 1 and the opening 6 for mounting the soundproof panel support with the padding 7 shown in FIG. 5, the sidewalk concrete plate 3 is integrated with the strength of the iron. Moreover, since the padding 7 is an iron horizontal screw type, the inner wall of the soundproof panel support 1 and the soundproof panel support opening 6 can be pushed firmly from the top of the opening even in a narrow opening, eliminating the gap completely. Prevents H steel from falling.

  As shown in FIG. 1, by inserting a soundproof panel 2 between the flanges of the soundproof panel support 1, the soundproof panel support 1 and the soundproof panel 2 protect pedestrians from collisions, sounds, and scattered objects of heavy equipment for construction. To do. Since the soundproof panel 2 is inserted into the groove between the flanges of the soundproof panel support (H steel) 1, the steps such as welding and bolting are omitted, and the workability is improved.

  The guard pipe strut hardware 10 is inserted and joined to the guard pipe strut 11 along the concave guard pipe strut hardware slide groove 8 shown in FIG. The support hardware slide groove 8 is provided with a reverse T-type cutting bar 9 for preventing the guard pipe from falling over, so that it does not fall down on the side of the roadway or the sidewalk. Moreover, the concave support | pillar hardware slide groove | channel 8 also plays the role of a drainage channel.

  When the guard pipe strut hardware 10 and the guard pipe strut 11 are not inserted into the concave guard pipe strut hardware slide groove 8, as shown in FIGS. 7, 8 and 10, a curb stone having a width of 10 cm to 22 cm, preferably 15 cm to 20 cm. It can also be used as a groove in which 16 is inserted.

  A pedestrian can install a grating 15 in the gap 8 between the guard pipe strut hardware 10 and the guard pipe strut hardware 10 formed between the guard pipe strut hardware 10 and the guard pipe strut hardware 10 shown in FIGS. Make sure that your feet do not fit into the hardware slide groove 8.

  By attaching the guard pipe 12 to the guard pipe column 11 shown in FIG. 5, the pedestrian is protected from jumping out from the sidewalk concrete plate 3 to the roadway side.

  As shown in FIGS. 6, 11, 12, 13, 14, and 15, the gap between the step receiving side 13 and the step restraining side 14 of the concrete plate 3 for sidewalks is widened up to a maximum of 40 cm on the fan-shaped arc side. It can be installed without losing integration by overlapping. The merit of integrating is to prevent the soundproof panel support 1 and the soundproof panel 2 from collapsing due to wind pressure in a strong wind, and to prevent the sidewalk concrete plate 3 from being displaced by a collision of a heavy machine for construction work or construction after installation. Also, fill the open gap with water and hold it with upper mortar. The step receiving side 13 also has a staircase function with a kick width of 10 cm to 20 cm and a tread width of 25 cm at the end.

  By integrating and integrating the concrete plates for sidewalks, the soundproof panel support 1 and soundproof panel 2 have a structure that can withstand strong winds due to the weight of the concrete plate 3 for sidewalks and the strength of H steel, and heavy equipment for construction collides. But H steel can protect pedestrians. By providing the step receiving side step suppressing side of the concrete plate 3 for sidewalk, the integration is not hindered even in the curved road portion. Concerning the gap generated in the curved road part, the step 10 cm to 20 cm on the receiving side restraint side can be used instead of the formwork, and if only one is covered, it can be pressed with sand and mortar and construction is easy. Moreover, a step of 20 cm to 40 cm is created by installing the concrete plate 3 for sidewalks, and the car can be stopped between the roadway and the sidewalk.

  Since the guard pipe strut hardware 10 is slidable, it can be installed at a free position, and processing and drilling at a guard pipe strut pitch can be omitted even on a curved road. By providing a cavity in the guard pipe strut hardware slide groove 8, it also functions as a drainage channel so that water cannot be collected on the sidewalk. When the guard pipe support hardware is not inserted, it can also be used as a groove for inserting and installing a curbstone, so that the installation position is not mistaken due to the work of drawing the ink and pulling the yarn, and the work is easy.

  The support metal slide groove 8 is provided with guard pipe toppling prevention reverse T-shaped cutting rods 9 at both ends of the bottom, and projections are applied to both ends of the bottom of the guard pipe support 10 to prevent the guard pipe from overturning.

  The soundproof panel support 1 is constructed so as to be built vertically from the opening 6 for the soundproof panel support at the top of the concrete plate. By using the padding 7, the gap is eliminated by the strength of the iron, preventing the fall, and the concrete plate for sidewalk 3 and integrated. Since it can be installed on the ground or asphalt without drilling anchors or H steel piles, it can be installed in a short period of time, and repair is not required after removal. After installation, separation by the step between the sidewalk and the roadway, separation between the sidewalk and the construction site by H steel and soundproof panel is done completely, so there is no need to arrange traffic directors or supervisors and reduce construction costs Is done.
