Description

  The present invention relates to a bracket used for a protective fence that is installed to prevent a pedestrian from crossing a roadway or to prevent a pedestrian from falling from a road to a river / waterway. The present invention relates to a bracket body that can be linearly supported and a protective fence using the bracket body.

  Some of the fences used at the borders of roadways and sidewalks to prevent pedestrians from crossing and to fall into rivers and waterways have beams or frame-shaped panel crosspieces connected and fixed to the columns. . In general, a connecting member called a bracket is used to connect the support column and the beam or the crosspiece of the panel. Conventionally used brackets are disclosed in Japanese Utility Model Laid-Open No. 63-116515.

  This bracket for a protective fence is composed of an arc-shaped column holding part and a horizontal beam holding part, and bent pieces are formed on the upper and lower ends excluding the tip of the horizontal beam holding part. By using this bracket, it has a feature that the beam or the crosspiece of the panel can be freely installed within a predetermined angle range one or simultaneously with respect to the road gradient or curve. In addition, since it is formed by bending a single flat plate, the column holding part for fixing to the column and the horizontal beam holding unit for fixing the beam or panel horizontal beam are integrally formed, and there is a feature that the number of members is small. ing.

FIG. 13 is a view showing a connecting step of a column and a horizontal rail using a bracket disclosed in Japanese Utility Model Laid-Open No. 63-116515. FIG. 13 is a partial cross-sectional view for convenience of explanation. (Step 1) First, the bracket is temporarily fixed to one of the columns with bolts. When temporarily fixing the bracket to the support column, bolts are tightened in the through holes on the support column side of the two through holes provided in the bracket so that the bracket does not slide off from the support column. For convenience of explanation, the bracket temporarily fixed first is a reference bracket and the other is a free bracket. (Step 2) Next, a beam or a crosspiece is inserted into the reference bracket. At this time, push the beam or the crosspiece as far as possible into the reference bracket. Since the conventional bracket is temporarily fixed with a bolt, the horizontal beam holding portion has a cylindrical shape, and the beam or the horizontal beam must be inserted from the opening of the horizontal beam holding unit. Therefore, when a pair of brackets face each other, it is necessary to insert a beam or a crosspiece into one bracket to the back. Furthermore, since the distance between the bracket openings is shorter than the length of the beam or the horizontal beam, it is necessary to insert the beam or the horizontal beam while rotating the free bracket with the opening of the free bracket as shown in the figure. There is. (Step 3) After determining the height position, orientation, etc. of the free bracket, it is temporarily fixed to the column with bolts, and the position of the bolt hole provided on the side surface of the beam or the side rail matches the position of the bolt hole provided on the bracket. Move the beam or crosspiece. (Step 4) Next, both the reference bracket and the free bracket are securely fastened with the bolts that have been temporarily fixed, and the brackets and the beam or the crosspiece are fastened with bolts. In this way, all the beams or crosspieces were connected to the column.
Japanese Utility Model Publication No. 63-116515

  However, the bracket disclosed in Japanese Utility Model Laid-Open No. 63-116515 has a problem that the connection between the column and the beam or the crosspiece is difficult, and the working efficiency is very poor. In the conventional bracket, the horizontal beam holding portion is normally opened radially, so when temporarily fixing the reference bracket to the support column, the horizontal beam holding unit must be closed to the extent that it can be temporarily fixed to the support column. However, since the conventional bracket is made of a single steel material and has a certain thickness, a considerable force is required to close the horizontal rail clamping portion. In addition, the bracket has to be fixed to the column while closing the horizontal beam holding portion with one hand, and the bolt must be temporarily fixed with the other hand, so that the work is very difficult and difficult.

  Furthermore, as described above, since the free bracket and the reference bracket must be temporarily fixed while frequently changing the position and angle of the beam or the cross beam, the number of work steps increases, and the work efficiency is extremely poor. have. Furthermore, in order to temporarily fix the free bracket, the position of the free bracket must be fixed with one hand while closing the horizontal bracket of the free bracket, and the free bracket must be inserted into the free bracket while holding the beam or panel with the other hand. It must be very difficult. In addition, after inserting the beam or panel into the free bracket while holding the beam or panel, the beam or side rail and the free bracket must be held, and the bolt must be temporarily fixed with the other hand, which is very difficult. Had the problem.

  When connecting a column and a beam with a conventional bracket, a long hole is provided in the beam and the bracket is fixed with a bolt or the like in order to absorb an installation error of an installation interval between adjacent columns. Using the bolt as an axis, the beam rotated and freely adapted to the gradient. However, since the beam is provided with a long hole, when the beam approaches the support column and is connected, it may come into contact with the support column when rotated. Therefore, it was necessary to provide a center of rotation further away from the support column so as to prevent the beam from interfering with the support column when rotated, so that the rotation center of the beam was separated from the support column. As a result, if the beam and panel crosspieces intersect the imaginary line parallel to the gradient and a plurality of beams and panels are installed, the beam and panel crosspieces will not be in a straight line but will be intermittent at the column. , Had a problem of lack of landscape. In addition, there is a problem that the angle of the panel becomes larger than the slope of the road and the adaptive range of the slope cannot be effectively used.

  In addition, the conventional bracket has a structure in which the bent pieces formed at the upper and lower ends have a gap with respect to the diameter of the beam or the horizontal beam, and thus the bracket protrudes in the vertical direction from the beam diameter. When the bracket is attached to the support via the bracket, there is a problem that the bracket stands out conspicuously when viewed from the road side and the sidewalk side.
