Description

  The present invention mainly relates to a temporary or permanent partition structure having mass and strength, which is easy to install along the construction of a traffic route of a vehicle and along each other.

  2. Description of the Related Art Conventionally, a partitioning structure has been installed so as not to hinder the safety of construction and the passage of a passing vehicle when the construction is performed on the road side of the vehicle's traffic route or when the left and right routes are partitioned. As the partition structure, a simple one such as a color cone (registered trademark) or a barricade made of steel, wood, resin, FRP, etc., concrete, or a combination of H-shaped steel and a guardrail, There is a combination of concrete blocks and guardrails, a steel plate processed into a unique shape, a steel material such as multiple H-shaped steels and lining plates, and a guardrail attached to the road side. There are various partition structures ranging from permanent to permanent. Among them, the permanent structure is used as a protection fence for a part of the permanent structure, and the vehicle is actually collided with the protection fence (actual vehicle collision test), and given to the behavior of the vehicle after the collision and the vehicle occupant. There are some which verify the influence, damage of the protective fence, etc., and use a protective fence having a structure and shape capable of ensuring safety.

  On the other hand, a protective wall is installed on the road side of the vehicle as a shielding means having a height to block noise, exhaust gas, scattered matter, etc. As the protective wall, a sound insulating plate, a universal wall, H There is a combination of shaped steel and wooden and steel sheet piles, a light-shielding net with a height, etc. These are constructed on the ground or floor slab of the construction site, or steel pipe Is placed in the soil and used as a foundation, and the above-mentioned wall-shaped objects are raised higher than the foundation.

  As described above, in the conventional partition structure related to the traffic route of a vehicle, a function as a mere partition between routes, a partition that separates a passage portion and a construction portion, or a function as a structure that prevents entry of a vehicle. As a partition structure with different purposes to satisfy its functions, it is different from the shielding function for preventing the entry of noise, exhaust gas, scattered matters, etc. It was built alone. Furthermore, for those requiring strength, a foundation was constructed at the construction site, and a structure was constructed on the foundation. Therefore, there has been no idea of quickly building a unit having various functions and strength as a single unit at the construction site.

  The work on the construction site having the existing traffic route is often accompanied by traffic regulation, and in some cases, it is required to perform more work within a limited time such as a predetermined time at night. The shortening of the work can suppress the occurrence of occupational accidents and the construction cost, but there are Patent Documents 1 and 2 described below as an attempt to speed up the construction at the construction site from this viewpoint.

  In Patent Document 1 shown in FIG. 10, a column mounting cylinder B is provided on the upper surface of the foundation A of the iron box, and an H-shaped steel insertion cylinder C is integrally mounted on the upper surface of the foundation A, and the column is mounted on the column mounting cylinder B. D is inserted, and a guard fence body E is fixed and supported on the upper part of the support column D by bolts and nuts. A support structure as a protective fence is provided by arranging a plurality of foundations A having the above-mentioned configuration at the construction site and inserting and connecting the H-shaped steel F to the H-shaped steel insertion tube C. The foundation A may be simply installed on the ground, or may be fixed to the ground with an anchor via a metal fitting G attached to the lower side of the foundation A, thereby shortening the work on the construction site. It is a thing.

  Further, Patent Document 2 shown in FIG. 11 uses an H-shaped steel J as a column base, and a column K is welded and fixed to the H-shaped steel J placed at a position to be temporarily installed at an appropriate interval. The material L is fastened and fixed with bolts and nuts. Although it takes time to weld the column K to the H-shaped steel J, the installation time at the construction site is shortened.

  Furthermore, as in Patent Document 2 shown in FIG. 12, a container-like column base P having a water inlet / outlet M and a column attachment portion O and capable of containing water is arranged at a construction site with an interval. Then, there is a temporary protective fence that attaches and installs the column R supporting the beam material Q to the column mounting portion O of the column base P, and then fills the space in the column base P with water. This is intended to shorten the installation of protective fences at the construction site.

  Moreover, there exists a technique like patent document 3 shown in FIG. 13 as a strong protection fence. The patent document 3 is a protective wall block used for a central separation band, and the protective wall block U is placed and fixed via a pile rod T protruding from the discarded mold S on the base side. Although a high-strength protective wall block can be easily installed on the foundation, the foundation has to be constructed at the construction site, either existing or new.

  On the other hand, Patent Document 4 shown in FIG. 14 is directed to a construction girder V in which a plurality of juxtaposed beams are arranged side by side with a leading end facing the construction side, and a column member W suspended from the rear ends of the plurality of girder V, An L-shaped guard consisting of a sheet pile X spanned between the pillars W and a work board Y that is a working flat laid on each spar V. The length of the spar V is 3.5 to 4 m. The length of the column member W is a protective fence having a height that can also serve as a partition with a main line vehicle of about 2 to 3.5 m. It has the strength to withstand the collision with the sheet pile X, such as the scattering of crushed materials and falling rocks, but the pillar material is intermittently exposed on the side where the vehicle collides. Does not have any function that should originally be owned as a protective fence. Therefore, in order to share the protective fence, it was necessary to consider a separate strength member such as providing additional means such as a steel beam material on the road side. Including that, the number of parts was large, and there was a defect that required a lot of time for on-site construction.

  As described above, the temporary partition structure has no weight and strength even when construction at the construction site is easy, and cannot cope with a large impact such as a vehicle collision. Also, in the case of building a protective wall block on the foundation, construction is impossible if there are underground pipes in the ground, and even if it can be done, it requires long work at the construction site. There was no temporary installation. Furthermore, the protective fence having a height is not strong and has a large number of parts as in the above-described conventional example, and it takes a lot of time to construct it.

  As described above, the conventional partition structure technology has a partition function, an impact response function, a shielding function for noise, exhaust gas, flying objects, etc., a blind function to avoid line of sight, or a function to make use of line of sight as one structure. It was not something that had to be combined.

JP 2001-20235 A Japanese Utility Model Publication No. 6-27920 JP-A-2-58606 Japanese Patent No. 3122637

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a partition structure 1 according to the present invention. The partition structure 1 is a guard fence (hereinafter referred to as a partition structure 1) that is installed or fixed on an installation surface such as a ground or a floor slab surface (hereinafter referred to as ground) G. The part mainly having a partition function and an impact response function by a passing vehicle located at the lower part of the vehicle is called a protective fence) 2 and a column 3a fixed to the protective fence 2 and a wall plate provided as a blocking member between the columns 3a 3b and a protective wall (hereinafter, a part mainly having a shielding function and a blindfold function located above the partition structure 1 is referred to as a protective wall) 3 and moves against the impact received by the protective fence 2 And a horizontal member 4 having a stable holding function such as holding the standing state of the protective fence 2 and the protective wall 3 stably. The partition structure 1 has strength and mass that can withstand wind loads, seismic forces, and the like by designing it as a continuous structure that is connected and fixed to its own weight and other partition structures. .

  The protective fence 2 is installed or fixed on a ground or floor slab (hereinafter referred to as ground) G such as a road surface or a road side, and includes a vertical portion 5 having a predetermined height and thickness, and is integrated with a horizontal member 4. The front side of the vertical portion 5 facing the passing vehicle is a small protruding portion, and the horizontal member 4 is formed as a large protruding portion on the back side. The front side is an inclined surface 7 that recedes upward at a position rising from the lower end of the tip 6 of the small protrusion, and the vertical portion 5 is inclined slightly upward from the upper end of the inclined surface 7 upward. The front part 8 having an inclined surface is formed, and a thick structure as a whole is formed.

  When a passing vehicle collides with the protective fence 2, the approach angle is often about 15 ° or less, and in the case of a contact level of a vehicle with a small contact state, the side surface of the wheel has a small protrusion and the tip portion 6 has a vertical shape. It is possible to avoid the vehicle main body from coming into contact with the front surface portion 8 in contact with the rising portion 9. In addition, as shown in FIG. 2 (a), when the approach speed is relatively low even if the approach angle is large, the wheel of the passing vehicle only needs to ride on the inclined surface 7 of the tip 6 of the small protrusion. The wheel that has ridden can move the vehicle body away from the protective fence 2 by the inclination of the inclined surface 7.

  However, as shown in FIG. 2B, when the speed of the vehicle is high or the approach angle is large, the wheel rides further upward than the inclined surface 7, and the wheel and the vehicle main body are placed on the front surface portion 8. A collision occurs and a large impact is applied to the vertical portion 5. Even if the front surface portion 8 is about the height of a normal vehicle or less, the inclined surface of the front surface portion 8 causes the vehicle to tilt away from the protective wall 3, and vehicle damage occurs at the lower portion. It will be within the height of the front face 8. Therefore, if the vertical portion 5 having a certain height is made thick enough to obtain mass and strength, direct impact response by the vehicle can be made at that portion.

  As described above, the vertical portion 5 having the front surface portion 8 has a thickness and a height enough to withstand the collision and collision, and the effect of dispersing the impact energy that the side surface of the vehicle is supposed to contact and the collision vehicle after the collision It has a guidance function that runs along a protective fence. Due to the direct impact, a force that moves in the direction of the back surface acts on the vertical portion 5, but the horizontal member 4 has a predetermined thickness from the bottom of the vertical portion 5 toward the back surface side. Since it is formed to extend, the vertical portion 5 serves as a movement preventing means by contact between its mass and the ground or by burial resistance.

  Further, in this embodiment, the front surface portion 8 of the vertical portion 5 of the protective fence 2 is continuously formed with the protective wall 3 at a position retracted from the upper end portion 10 to the rear surface side. The distance from the protective wall 3 can be further increased, and the collision can be dealt with only the protective fence 2 portion. Furthermore, it is possible to eliminate or extremely reduce the impact such as the collision of the vehicle and the contact of the scattered parts caused by the vehicle damage, thereby eliminating the need to damage the protective wall 3 and the accompanying replacement. .

  The height of the vertical portion 5 is defined as the height of the vertical portion 5 up to the upper end portion 10 of the front surface portion 8. In the vertical portion 5, the lower portion of the pillar 3 a is embedded and fixed in the longitudinal direction, and the upper portion extends outward from the upper end portion 10. As the member of the column 3a, an H-shaped steel is optimal, and the flange surface of the H-shaped steel is fixed toward the front surface portion 8 side, so that the web between the flanges is orthogonal to the longitudinal direction of the vertical portion 5. It becomes the position to do.

  The number of the pillars 3a is embedded and fixed as appropriate according to the length of the protective fence 2 in the installation direction, the required strength, and the like. Further, in terms of structure and rust prevention, the front and rear flanges are embedded and fixed at the inner position from the surface of the concrete to be placed, and the embedded position has retreated from the position of the upper end portion 10 of the front surface portion 8. The front flange is located at the position. Since the wall plates 3b, 3c,... Described later do not protrude forward from the column 3a, the protection wall 3 composed of the columns 3a,... And the wall plates 3b, 3c,. 2 is erected at a position retracted from the upper end 10.

  The wall plates 3b, 3c,... Are provided between the webs of the adjacent pillars 3a facing each other. FIG. 3 shows two embodiments of the wall plates 3b, 3c,. As one example, a belt-like wall plate 3b having a relatively low height is fitted and attached between recesses formed by front and rear flanges and webs of adjacent columns 3a. The wall plate 3b is inserted from the upper part. The height of the wall plate 3b can be appropriately selected as necessary. The wall plate 3b may be a rectangular long plate. However, the upper and lower edges of the wall plate 3b are provided with uneven portions and L-shaped engaging portions to achieve vertical engagement without any gap. can do.

  In another embodiment, the wall plate 3c is a large rectangular plate, the height is approximately the same as the height of the extended column 3a, and the width is a length that fits between adjacent webs. A wall body can be formed by inserting the wall plate 3c from above between adjacent webs of the pillar 3a.

  The protective wall 3 prevents noise and exhaust gas from entering, protects against flying objects and inputs, shields that prevent flying objects generated from the work on the back side from jumping out to the road, blinding function to avoid line of sight, or conversely It is not necessary to use a member that can withstand the impact of the above-described vehicle collision. Therefore, the wall board 3b may be made of concrete, fiber-made concrete, or other materials, and the thickness can be reduced to about several cm to 20 cm. A variety of materials can be used as long as they can provide strength and mass that can withstand wind loads and seismic forces. In some cases, a transparent or translucent glass or acrylic plate having a thickness of several centimeters or less can be used to show the scenery outside the road without requiring blindfolding.

  FIG. 4 shows another embodiment of the partition structure 11 of the present invention. As in the first embodiment, the partition structure 11 prevents the guard fence 12 and the guard wall 13 above the guard fence 13 and the guard fence 12 from moving against an impact, and the guard fence 12 and the like. It comprises a horizontal member 14 having a stable holding function such as holding the standing state of the protective wall 13 stably.

  In the present embodiment, an embedding hole 16 for mounting a pillar is provided at an appropriate position of the vertical portion 15 of the protective fence 12, and a lower portion of the column 13a is inserted into the embedding hole 16 at a factory or a construction site. Concrete or mortar is poured into the insertion hole 16 to fix the column 13a. The filling hole 16 may be filled with sand or the like as long as the pillar 13a can be fixed at a predetermined position, and in that case, it can be disassembled again after temporary use and reused in the same procedure.

  As in the first embodiment, wall plates 13b, 13c,... Are appropriately attached to the pillar 13a fixed to the protective fence 12. Further, the wind load, seismic force, etc. or the relationship with the vehicle is the same as in the first embodiment.

  Fig.5 (a) has shown the other Example of the partition structure 17 of this invention. As in the first and second embodiments, the partition structure 17 includes a guard fence 18, a guard wall 19 and a horizontal member 20 located above the guard fence 18.

  As in the second embodiment, an embedding hole 22 for pillar mounting is provided at an appropriate position of the vertical portion 21 of the protective fence 18, and the lower portion of the column 19a is inserted and fixed in the embedding hole 22 at the construction site. The wall plate 19b is attached to the column 19a in advance, and the mounting of the wall plate 19b is completed simultaneously with the fixing of the column 19a.

  In this embodiment, the protective fence 18 is formed with two embedded holes 22, and the two pillars 19 a and 19 a and the three lateral members 19 c inserted into the embedded hole 22 as the protective wall 19 and the transverse members 19 c are provided. The figure shows a structure formed by a frame formed by three connecting members 19d protruding in the horizontal direction continuously to the horizontal member 19c, and a wall plate 19b fixed to the frame.

  The protective wall 19 is lifted using a crane or the like, the lower portions of the pillars 19a and 19a are inserted into the embedded holes 22 and 22, respectively, and the embedded holes 22 and 22 are filled with concrete, mortar or the like and hardened. Thus, the partition structure 17 is completed. Further, even if the filling hole 22 is not solidified, such as sand, it is only necessary that the pillar 19a can be fixed at a predetermined position. In that case, it can be disassembled again after temporary use and reused in the same procedure.

  FIG. 5B shows a state in which the partition structure 17 is connected to another adjacent partition structure 17 ′. By connecting the connecting member 19d protruding in the lateral direction of the frame to the adjacent horizontal member 19c 'of the frame, a structure extending in the longitudinal direction can be obtained.

  In addition, a force that moves toward the back side acts on the vertical portion 18 due to the impact of the vehicle, but the horizontal member 20 has a predetermined thickness from the bottom of the vertical portion 18 toward the back side. Since it extends and is in contact with the ground, the horizontal member 20 serves as a movement preventing means that resists impact.

  FIG. 6 shows another embodiment of the partition structure 23 of the present invention. It can be applied to all of the first to third embodiments, and the rear of the horizontal portion due to a construction place where there is no margin on the back side with respect to the installation or fixing of the partition structure 23 to the ground G or for other reasons. When it is desired to reduce the extension to the rear, the extension length of the horizontal member 25 on the rear side of the protective fence 24 to the rear is reduced, and instead the thickness is increased.

  In addition, when a sufficient length cannot be obtained behind the protective fence 24, but it is desired to reduce the weight as much as possible with respect to the installation of the partition structure 23 at the site, the weight is increased in order to increase the mass and stability after the installation. As an increasing means, a heavy object 26 is mounted on the upper surface of the horizontal member 25.

  As the heavy object 26, anything that has a weight and can be mounted on the horizontal member 25, such as a steel frame, a concrete lump, a bag or a container enclosing earth and sand, or a liquid, can be used.

  In FIG. 7A, there is room for extending a horizontal member 29 extending from the back of the guard fence 28 behind the partition structure 27. However, the partition structure 27 is reduced in weight and can be easily installed. In the same way as in the fourth embodiment, in addition to the loading of the heavy object 30, the mass increasing auxiliary material 31 is connected to the rear of the horizontal member 29.

  At the rear end of the horizontal member 29, a bolt hole 32 for attaching a connecting metal fitting to be integrated with the heavy mass auxiliary material 31 is provided, and between the horizontal member 29 and the mass additional auxiliary material 31. The weight of the partition structure 27 can be increased by integrating with the connecting metal fitting 33 straddling.

  In addition, a notch portion corresponding to the thickness of the connecting bracket is provided at the rear end portion of the upper surface of the horizontal member 29, and a similar notch portion is provided at the front end portion of the upper surface of the mass augmentation auxiliary material 31, and both are connected by the connecting bracket. In addition, a notch portion corresponding to the thickness of the connecting metal fitting is provided at the rear end portion of the lower surface of the horizontal member 29, and a similar notch portion is also provided at the front end portion of the lower surface of the mass expansion auxiliary member 31, and both are connected via the connecting metal fitting. Can be integrated. Various connecting means can be appropriately selected as means for integrating.

  FIG. 7B shows another embodiment in which a mass expansion auxiliary material 35 is provided behind the horizontal member 34, and concrete is placed on the site as the mass expansion auxiliary material 35. A notch 36 is provided in the upper part of the rear end of the horizontal member 34, and a mass increasing auxiliary material 35 is integrally provided behind the horizontal member 34 by placing concrete so as to fill the notch 36. it can. It is also possible to form a reinforcing bar and a reinforcing bar that match the above shape in advance and then place concrete on it. As long as the cast concrete can be integrated with the horizontal member 34, it is not limited to the notch 36.

  FIG. 8 shows that the ground G is obstructed when the stability of the installation of the partition structure 37 is further strengthened or when the auxiliary member for mass expansion cannot be provided on the horizontal member 39 continuous on the back side of the protective fence 38. The partition structure 37 can be anchored at the construction site on the condition that an object or the like is not buried. By providing a through-hole 41 from the top to the bottom of the tip 40 of the protective fence 38, the horizontal member 39, etc., the anchor 42 can be inserted and driven and firmly fixed to the ground G.

  Also, the L-shaped metal fitting 43 is brought into contact with the rear end portion of the horizontal member 39, and one is fixed to the end vertical portion 44 of the horizontal member 39 and the other is fixed to the ground G. 37 can be firmly fixed on the ground G. In order to fix the L-shaped metal fitting 43, a horizontal bolt hole may be provided in the end vertical portion 44 in advance.
