JP 7-292632 A Japanese Patent Laid-Open No. 10-88537 Utility Model Registration No. 3011701 JP 2000-27134 A

  In the above Patent Documents 1 to 4, there are proposed mounting brackets having a structure in which the protrusion of the support to the sidewalk side is suppressed.

  However, in the proposals disclosed in these patent documents, the horizontal beam holding portion is divided into two parts in the vertical direction and the front-rear direction, so that it is easily deformed or destroyed when the vehicle collides. Moreover, when a one-side bolt is used, the number of parts of the attachment part to a support | pillar will become many and will become complicated.

  The object of the present invention is to make it difficult to be deformed or destroyed even if a vehicle collides with a horizontal rail or a horizontal rail mounting bracket, and has a structure that suppresses the protrusion of a fixing bolt for fixing the horizontal rail mounting bracket to a column. It is in providing a horizontal rail mounting bracket of a protective fence and a protective fence using the same.

  As a result of various studies on the shape of the horizontal rail mounting bracket and the shape of the fixing bolt for mounting the horizontal rail mounting bracket to the column, the present inventors obtained the knowledge shown in the following (a) to (p) Completed the invention.

  (a) When the vehicle collides with the horizontal beam or the horizontal beam mounting bracket, in order to prevent the horizontal beam mounting bracket from being deformed or destroyed, the horizontal beam mounting bracket should be housed in the column as much as possible.

  (b) When a vehicle collides with a horizontal beam or a horizontal beam mounting bracket, the load should be received by the entire horizontal beam mounting bracket or the entire column. For this purpose, it is preferable to accommodate the horizontal rail mounting bracket in the column as much as possible.

  (c) In order to accommodate the horizontal rail mounting bracket in the column, an opening may be formed on the side surface of the column on the holding member side that holds the horizontal beam.

  (d) In order to accommodate the horizontal rail mounting bracket in the column as much as possible, it is preferable that the holding member is constituted by a holding portion installed on the outer surface of the column and a bracket that can be inserted into the side opening of the column. The holding portion and the bracket may be formed separately and then joined, or may be formed integrally. When it is desired to accommodate the bracket in the column below the position of the holding portion, a connecting portion may be interposed between the holding portion and the bracket. When passing through the connecting portion, it may be formed separately and then joined, or may be formed integrally.

  (e) To fix the bracket inserted in the side opening of the column to the column, attach the mounting auxiliary member to the side wall of the column opposite to the bracket insertion opening, and insert the bracket. And what is necessary is just to fix a bracket to a support | pillar via an attachment member with a fixing bolt.

  (f) In order to fix the bracket to the support via the mounting support member with the fixing bolt while the bracket is inserted into the side opening of the support, pass the fixing bolt horizontally through both the bracket and the mounting support member. A vertical wall provided with a hole or a screw hole may be provided, and the two vertical walls may be fixed with fixing bolts. The shape of the auxiliary mounting member may be a plate shape, or may be a cylindrical shape or a frustum shape. When the vertical wall of the bracket and the vertical wall of the mounting auxiliary member are fixed with fixing bolts, the vertical walls may be in contact with each other or may be separated from each other. Moreover, when using a cylindrical or frustum-shaped attachment auxiliary member, the vertical wall may be formed separately from the cylindrical portion or the frustum portion, and may be joined, or may be integrally formed.

  (g) When a holding member having a connecting portion is used between the holding portion and the bracket, the bracket can be accommodated in the column below the position of the holding portion. Therefore, it can also be designed so that the bracket fixing bolt can be fixed from the bracket insertion column opening. In this case, since the support opening for inserting the bracket can also serve as the opening for fixing the bolt, it is not necessary to form the opening for fixing the bolt on the side of the support.

  (h) As described above, if the shape of the auxiliary mounting member is a plate, the fixing bolt can be accommodated in the column. And if the shape of an attachment auxiliary member is made into a cylinder shape or a frustum shape, the whole fixing bolt can be accommodated in a support | pillar. A nut may be used to fix the bolt, but the entire fixing bolt including the nut used at this time can be accommodated in the column.

  (i) The head of the fixing bolt may be located on either the mounting auxiliary member side or the bracket side. The tip of the bolt may be inserted into a screw hole or may be inserted into a through hole. However, when inserting into a through-hole that is not cut by an internal thread, a nut for fixing the bolt is required. When inserting into the through hole in which the female thread is cut, a nut for fixing the bolt may be used, or the use of the nut may be omitted.

  (j) If the outer shape of the bracket is matched with the shape of the opening provided on the side of the column, the load can be firmly received by the entire column when the vehicle collides with the horizontal beam or the horizontal beam mounting bracket. it can.

  (k) If both the cross-sectional shape of the outer surface of the bracket and the shape of the opening provided on the side of the column are made circular, the bracket is inserted into the column with the through-hole or screw hole through which the fixing bolt is passed as the rotation axis. Can be rotated with respect to the column, and the mounting angle of the horizontal beam with respect to the column can be freely set. At this time, the vertical walls may be in contact with each other or may be separated from each other.

  (l) It is preferable that the vertical wall of the bracket and the vertical wall of the mounting auxiliary member are rotatably fitted. When the mounting auxiliary member and the vertical wall of the bracket are fitted to each other, when the vehicle collides with the horizontal rail or the horizontal rail mounting bracket, the load can be more firmly received by the entire mounting auxiliary member and the bracket.

(m) In order to hold and fix the end portion of the horizontal rail, a bolt insertion hole may be provided in the holding portion and the end portion of the horizontal rail may be fixed to the holding portion. If the inner shape of the holding portion is adapted to the outer shape of the end portion of the horizontal rail, the end portion of the horizontal rail can be securely fixed to the holding portion. For example, when the end of the horizontal rail is cylindrical, the shape of the inner surface of the holding portion may be cylindrical, and when the cross-sectional shape of the end of the horizontal rail is rectangular, the cross-sectional shape of the inner surface of the holding portion is A rectangle may be used. In addition, if it is made to surround substantially the entire circumference of the end portion of the horizontal rail on the inner surface of the holding portion, it can be securely fixed.
(n) Instead of directly holding the end of the horizontal rail by the holding portion, an inner sleeve may be installed to fix the end of the horizontal rail to the holding portion. The inner sleeve may be installed directly inscribed in the holding portion, or may be installed inscribed through the end of the horizontal rail.

  (o) When installing the inner sleeve directly inscribed in the holding part, prepare an inner sleeve longer than the length of the holding part and fix the inner sleeve directly inscribed in the holding part. One end of the cross rail is extrapolated to each end of the inner sleeve that protrudes from both ends of the holding portion. At this time, if the outer diameter of the horizontal rail and the outer diameter of the holding portion are the same, the horizontal rail and the holding portion are arranged in a straight line with the same outer diameter, so that a protective fence with a clean appearance can be obtained.

  (p) When the inner sleeve is installed in contact with the holding portion through the end of the horizontal rail, the length of the inner sleeve may be longer than the length of the holding portion, but may be slightly shorter. Absent. Each end of the inner sleeve is inserted into the holding portion at each end of the inner sleeve, and both ends of the inner sleeve and the horizontal rail are fixed to the inner surface of the holding portion. In this case, the cross-sectional shape does not have to be around the entire circumference of the end of the horizontal rail on the inner surface of the holding part, and a part of the cross-sectional shape may be suitable. The degree is increased. For example, when the end portion of the horizontal rail is cylindrical, the inner shape of the holding portion may be a semi-cylindrical shape obtained by dividing the cylinder vertically in half, or may be obtained by dividing it by a quarter. A quarter cylinder may be used. At this time, since the shape of the holding portion can be reduced, the horizontal rails are arranged in a straight line, and a protective fence with a clean appearance can be obtained.

  The gist of the present invention is the horizontal rail mounting bracket for the protective fence shown in the following (1) to (13) and the protective fence shown in the following (14). Hereinafter, the inventions according to (1) to (14) may be collectively referred to as the present invention.

  According to the present invention, it is difficult to be deformed or destroyed even when a vehicle collides with a horizontal rail or a horizontal rail mounting bracket, and has a structure in which a protrusion of a fixing bolt for fixing the horizontal rail mounting bracket to a column is suppressed. A horizontal rail mounting bracket for a protective fence and a protective fence using the same can be provided.

  In addition, when the outer surface of the bracket has a cylindrical or frustoconical shape, the mounting angle to the column can be adjusted according to the slope of the road. A metal fitting and a protective fence using the metal fitting can be provided. In this case, even if the mounting angle to the column is adjusted, the horizontal beam mounting bracket having the same shape can be used, so that there is an advantage that it is not necessary to separately prepare a special shape horizontal beam mounting bracket.

  Below, the holding bolt used for the horizontal rail mounting bracket which concerns on this invention, an attachment auxiliary member, and the fixing bolt for attaching a holding member to a support | pillar via an attachment auxiliary member are demonstrated. Also, a description will be given of a protective fence obtained by holding the end of the horizontal rail directly or by installing an inner sleeve on the holding portion of the holding member and attaching it to the column.

A. About the holding member The holding member that forms a part of the horizontal rail mounting bracket according to the present invention includes a holding portion for holding the horizontal rail and a bracket whose outer surface is cylindrical or frustum-shaped. It has a vertical wall with through holes or threaded holes that pass in the direction. And a bracket is inserted in the opening part formed in the side surface by the side of the roadway of a support | pillar, and is fixed to a support | pillar via the attachment auxiliary member mentioned later.

  The inner surface shape of the holding portion may be any shape as long as the inner surface can hold and fix the end portion of the cross rail directly or via the inner sleeve. In addition, there is no restriction | limiting of the outer surface shape of a holding | maintenance part.

  And the outer surface shape of a bracket should just have the shape of the cylinder or frustum shape which can be inserted in the opening part formed in the side surface by the side of the roadway of a support | pillar. For example, a cylindrical shape or a rectangular cylindrical shape, a truncated cone shape or a truncated pyramid shape. The inner surface of the bracket only needs to have a space for installing a fixing bolt or nut for fixing the bracket and the mounting auxiliary member, and the inner surface of the bracket may be hollow or solid. When the inner surface of the bracket is hollow, the inner surface shape is not particularly limited, and examples thereof include a truncated cone shape and a truncated pyramid shape, and a cylindrical shape and a rectangular cylindrical shape.

  The material of the holding member is not particularly limited for both the holding part and the bracket, but plastics such as polyester can be used in addition to metals such as aluminum, carbon steel, and stainless steel. Further, the holding portion and the bracket may be formed integrally, or may be formed separately and joined by welding, bolts and nuts, or the like. If the holding portion and the bracket are integrally formed, even if the vehicle collides with the protective fence and stress is applied to the holding portion and the bracket, the holding portion and the bracket are not easily deformed.

  When it is desired to accommodate the bracket in the column below the position of the holding portion, a connecting portion may be interposed between the holding portion and the bracket. Even when the connection portion is interposed, they may be formed separately and then joined, or may be integrally formed.

B. About the mounting auxiliary member The mounting auxiliary member forming a part of the horizontal rail mounting bracket according to the present invention is a bolt fixing formed on the side opposite to the opening on the side surface of the column on the roadway side, that is, on the side surface of the column on the sidewalk side. And a vertical wall having a through hole or a screw hole through which the fixing bolt passes in the horizontal direction. The shape of the auxiliary mounting member may be a plate shape, or may be a cylindrical shape or a frustum shape. And a bracket is fixed to a support | pillar via a mounting auxiliary member with a fixing bolt.

  In addition, when a holding member having a connecting portion is used between the holding portion and the bracket, the bracket can be accommodated in the support below the position of the holding portion. The bracket fixing bolt can be designed to be fixed from an opening formed on the roadway side. At this time, since the support opening for inserting the bracket can also serve as the opening for fixing the bolt, it is necessary to join the mounting auxiliary member to the wall of the side of the support on the opposite side. It is not necessary to form an opening for bolt fixing operation.

  The material of the attachment auxiliary member is not particularly limited, but plastics such as polyester can be used in addition to metals such as aluminum, carbon steel, and stainless steel.

  The shape when using a plate-like member as the attachment auxiliary member is not particularly limited. For example, a circular shape, an oval shape, a rectangular planar shape, or a bent shape thereof can be used. Moreover, the inner surface shape when using a cylindrical or frustum-shaped member as the attachment assisting member is not particularly limited. For example, a cylindrical shape or a rectangular cylindrical shape, a truncated cone shape or a truncated pyramid shape. The outer surface shape of the mounting auxiliary member is not particularly limited, and examples thereof include a cylindrical shape or a rectangular cylindrical shape, a truncated cone shape or a truncated pyramid shape.

  There is no restriction | limiting in particular as a method of joining the edge part of an attachment auxiliary member to the wall surface of the opening part for bolt fixation operation formed in the support | pillar, and welding, snapping, screwing, adhesion | attachment, etc. can be used. Welding can be performed by, for example, the open end of the wall surface of the opening or the entire circumference of the inner wall surface or spot welding. The fitting is possible when a cylindrical or frustum-shaped mounting auxiliary member is used as the mounting auxiliary member. For example, the mounting auxiliary member is inserted into the opening while the support column is elastically deformed by an external force. After removing the external force, or by removing the external force after inserting the mounting auxiliary member into the opening with a part of the mounting auxiliary member elastically deformed by the external force, the mounting auxiliary member is restored to its original shape. It remains in the opening. At this time, it is preferable to use an adhesive in combination.

  If the bracket insertion column opening can also serve as a bolt fixing operation opening, the bolt fixing operation opening should be formed on the side of the column opposite to the bracket insertion column opening. Although not necessary, the end of the attachment assisting member when the opening is not formed is joined to the inner wall surface of the side surface of the opposite column. The method at this time is not particularly limited, and welding, screwing, adhesion, or the like can be used. For example, welding can be performed by spot welding.

C. Inserting the bracket into the column opening The bracket is inserted into the opening formed on the side of the column on the side of the roadway, and on the side of the column opposite the roadway side, that is, on the side wall of the column on the side of the sidewalk It is fixed by a fixing bolt between the attachment auxiliary members to be joined, that is, between the vertical wall of the bracket and the vertical wall of the attachment auxiliary member.

  At this time, if the outer shape of the bracket is adapted to the shape of the opening formed on the side surface of the column on the roadway side, when the vehicle collides with the horizontal beam or the horizontal beam mounting bracket, the load is firmly applied to the entire column. I can take it. In addition, when the outer shape of the bracket is cylindrical or frustoconical, the bracket can be used as a support shaft with a through hole or screw hole through which the fixing bolt is passed as a rotation axis even after the bracket is inserted into the opening formed on the side surface of the support. On the other hand, it can be rotated, and the mounting angle of the horizontal rail becomes free. At this time, the vertical wall of the bracket and the vertical wall of the mounting auxiliary member may be in contact with each other or may be separated from each other.

  Further, when the vertical wall of the bracket and the vertical wall of the mounting auxiliary member are rotatably fitted, when the vehicle collides with the horizontal beam or the horizontal beam mounting bracket, the load is further increased in the entire bracket and the mounting auxiliary member. It can be taken firmly.

D. About the fixing bolt for attaching a holding member to a support | pillar The fixing bolt for attaching the holding member which concerns on this invention to a support | pillar is for fixing a bracket to a support | pillar via an attachment auxiliary member. Each of the bracket and the mounting auxiliary member has a vertical wall having a through hole or a screw hole, and after passing the fixing bolt through the through hole or screw hole in the horizontal direction, the bracket is tightened by tightening the fixing bolt. Secure to the mounting aid. At this time, the vertical walls may be in contact with each other or may be separated from each other.

  The head of the fixing bolt may be located on either the roadway side or the sidewalk side. The tip of the bolt may be inserted into a screw hole or may be inserted into a through hole. However, when inserting into a through-hole that is not cut by an internal thread, a nut for fixing the bolt is required. When inserting into the through hole in which the female thread is cut, the use of a nut can be omitted, but a nut may be used in combination. A nut may be used to fix the bolt, but the entire fixing bolt including the nut used at this time can be accommodated in the column.

  Further, the shape of the head of the fixing bolt is not particularly limited. For example, a bolt having an outer surface having a hexagonal shape, a square shape, a round shape, or the like can be used. If the outer surface of the head is a cylindrical bolt (with a recessed head and a hexagonal or square cross section inside it), the diameter of the bolt fixing opening provided on the side of the column should be reduced. Can do.

E. Attaching the horizontal rail to the holding portion of the holding member When holding the end of the horizontal rail to the holding portion of the holding member according to the present invention, it may be held directly, or an inner sleeve is installed and held. May be.

  When fixing the end of the horizontal beam to the holding part directly without using the inner sleeve, if the inner shape of the holding part is adapted to the outer shape of the end of the horizontal beam, the end of the horizontal beam becomes the holding part. It can be fixed securely. For example, when the end of the horizontal rail is cylindrical, the shape of the inner surface of the holding portion may be cylindrical, and when the cross-sectional shape of the end of the horizontal rail is rectangular, the cross-sectional shape of the inner surface of the holding portion is A rectangle may be used. In addition, if it is made to surround the perimeter of the edge part of a horizontal crossing with the inner surface of a holding | maintenance part, it can fix reliably. At this time, the outer diameter of the end portion of the horizontal rail is the same as the inner diameter of the holding portion.

  Attachment of the cross rail to the holding portion of the holding member can be performed by the following procedure. That is, the end of the horizontal beam is inserted into one end of the holding unit in advance and fixed with the horizontal beam fixing bolt and the horizontal beam fixing nut, and then the bracket is attached to the column via the mounting auxiliary member. The bracket may be fixed with a fixing bolt, or the bracket may be fixed to the column via the auxiliary mounting member after being inserted into both ends of the holding portion and fixed in advance. Or after fixing a bracket to a support | pillar via an attachment auxiliary member, the edge part of a horizontal beam may be inserted in the edge part of a holding | maintenance part, and the bolt for horizontal beam fixation may be fixed.

  In this way, when one or two or more horizontal rails are attached to a plurality of columns using the holding member, the attachment auxiliary member, and the fixing bolt according to the present invention, a protective fence is obtained. In this protective fence, since the fixing bolt is accommodated in the column, the fixing bolt for mounting to the column does not protrude toward the sidewalk, and a clean appearance can be obtained. In particular, when a bracket having an outer surface of a cylindrical shape or a truncated cone shape is used, the bracket can be rotatably mounted on the support column, so that the mounting angle of the horizontal beam can be freely set. Therefore, even on a sloped road, it is easy to attach to the support column, and a protective fence with a clean appearance can be obtained.

  On the other hand, when the inner sleeve is installed and the end of the horizontal beam is fixed to the holding unit, the inner sleeve is installed directly in the holding unit or is inscribed through the end of the horizontal beam. May be installed.

  The inner sleeve has a cylindrical shape, and a bolt insertion hole is provided to fix the inner sleeve to the holding portion of the holding member and to fix the end of the horizontal rail to the inner sleeve. In the bolt insertion hole provided in the inner sleeve, a female screw is cut, or instead of cutting the female screw, a nut is joined to the inner surface of the inner sleeve by welding or the like. A nut may be used in combination with the female thread being cut.

  When installing the inner sleeve directly inscribed in the holding part, prepare an inner sleeve longer than the length of the holding part, fix the inner sleeve in contact with the holding part, and then protrude from both ends of the holding part. One end of the cross rail is extrapolated to each end of the inner sleeve. Since the inner sleeve at this time requires a bolt insertion hole for fixing the inner sleeve to the holding portion of the holding member and a bolt insertion hole for fixing the end portion of the horizontal rail to the inner sleeve, At least three bolt insertion holes are required. If the outer diameter of the horizontal rail and the outer diameter of the holding portion are the same, the horizontal rail and the holding portion are arranged in a straight line with the same outer diameter, so that a protective fence with a clean appearance can be obtained.

  The installation procedure when the inner sleeve is installed directly inscribed in the holding portion is as follows. First, the holding portion is prepared with a bolt insertion hole drilled in at least one place. Then, extrapolate the end of the horizontal beam to one end of the inner sleeve in advance and fix the inner sleeve and the end of the horizontal beam with the horizontal beam fixing bolt of the inner sleeve, and then fix with the horizontal beam fixing bolt of the holding part Alternatively, it is possible to extrapolate the end of the cross rail to both ends of the inner sleeve in advance and fix the end of the inner sleeve and the cross rail with the cross rail fixing bolt of the inner sleeve before holding the holding portion. It may be fixed with the horizontal beam fixing bolt. Alternatively, the inner sleeve is inscribed in the holding portion and fixed with the horizontal rail fixing bolt of the holding portion, and then the end of the horizontal rail is extrapolated to one or both ends of the inner sleeve and fixed with the horizontal rail fixing bolt of the inner sleeve. May be.

  On the other hand, when the inner sleeve is installed in contact with the end of the horizontal rail, the length of the inner sleeve is preferably longer than the length of the holding portion, but may be slightly shorter. . After the end portions of the cross rails are extrapolated to both ends of the inner sleeve, the end portions of the two cross rails are inscribed in one holding portion. That is, the inner sleeve is inscribed in the holding portion via both end portions of the horizontal rail. The inner sleeve at this time can serve both as a bolt insertion hole for fixing the inner sleeve to the holding portion of the holding member and a bolt insertion hole for fixing the end of the cross rail to the inner sleeve. There may be two bolt insertion holes to be drilled. Of course, a bolt insertion hole for fixing the end of the cross rail to the inner sleeve may be provided separately. The outer diameter of the end portion of the horizontal rail is the same as the inner diameter of the holding portion, and the outer diameter of the inner sleeve is the same as the inner diameter of the end portion of the horizontal rail.

  The attachment procedure in the case where the inner sleeve is installed in contact with the holding portion via the end portion of the horizontal rail is as follows. First, the holding part is prepared with two bolt insertion holes. Then, one end of the inner sleeve is inserted into the end of the horizontal rail. At this time, the fixing bolt insertion hole formed in the inner sleeve and the fixing bolt insertion hole formed in the end portion of the horizontal rail are aligned. With this alignment, the end of the cross rail in which the end of the inner sleeve is inserted is inscribed in the holding portion. At this time, alignment is also performed with the fixing bolt insertion hole formed in the holding portion. Then, the horizontal beam fixing bolts of the holding unit are passed through the three fixing bolt insertion holes of the holding unit, the end of the horizontal beam, and the inner sleeve. Then, the edge part of a crosspiece is extrapolated to the edge part on the opposite side of an inner sleeve. In the same manner, the horizontal beam fixing bolt of the holding unit is passed through the three fixing bolt insertion holes of the holding unit, the end of the horizontal beam, and the inner sleeve. Thereafter, the crosspiece fixing bolts passed through the two bolt insertion holes of the holding portion are fixed by tightening.

  When the inner sleeve is installed in contact with the holding portion via the end of the horizontal rail, the inner shape of the holding portion is such that the inner surface of the holding portion surrounds almost the entire circumference of the end of the horizontal rail. Not only that, but a part of the shape may be suitable. For example, when the end portion of the horizontal rail is cylindrical, the inner shape of the holding portion may be a semi-cylindrical shape obtained by dividing the cylinder vertically in half, or may be obtained by dividing it by a quarter. A quarter cylinder may be used. At this time, since the shape of the holding portion can be reduced, the horizontal rails are arranged in a straight line, and a protective fence with a clean appearance can be obtained.

  Moreover, as for the shape of the opening formed on the side surface of the support column, the opening on the roadway side only needs to have a shape into which the bracket can be inserted, but it is preferable to match the shape of the outer surface of the bracket. For example, a circle or a rectangle can be mentioned. The opening on the sidewalk only needs to be capable of fixing a bracket fixing bolt or a nut thereof for fixing the bracket to the support via the mounting auxiliary member, and examples thereof include a circle and a rectangle. However, if a holding member with a connecting part is used between the holding part and the bracket, it can also be designed so that the bracket fixing bolt can be fixed from the support column opening for bracket insertion. It may not be necessary to form the opening on the side in the column.
