  According to the above-described conventional mounting bracket A, the horizontal beam 22 can be temporarily placed on the receiving bracket 23. Therefore, the mounting of the lateral beam 22 to the support column 21 can be easily performed, but the receiving bracket mounting bolt 27 is indispensable. Therefore, the appearance is bad and material costs are required.

  According to the above-described conventional mounting bracket B, the fixing bolt 41 is not exposed, and thus the appearance is excellent, but the fixing bolt 41 is indispensable, so that the material cost is increased. Moreover, since it is difficult to fasten the fixing bolt 41, it takes time to attach the lateral beam 40 to the column 37.

  Therefore, the object of the present invention is that the horizontal beam can be temporarily placed, so that the horizontal beam can be easily attached to the column, and the fixing bolt for the horizontal beam mounting bracket for fixing the horizontal beam mounting bracket to the column is unnecessary. Therefore, also from this point, it is an object to provide a horizontal beam mounting bracket for a protective fence that can easily attach a horizontal beam to a support column, has an excellent appearance, and can reduce costs.

  The present invention has been made to achieve the above object, and is characterized by the following.

The invention according to claim 1 is a protective fence transverse beam mounting bracket for attaching a transverse beam to a support made of a round pipe , and has a shape in which a tubular body having a contact surface with the support at one end is halved. The horizontal beam mounting bracket body has a pair of symmetrical horizontal beam mounting bracket bodies, the upper corner portion of the horizontal beam mounting bracket body has a notch, and the lateral beam is mounted on the side surface of the horizontal beam mounting bracket body. A bolt hole is formed through which a horizontal beam mounting bolt to be mounted on the beam mounting bracket main body is inserted, and a protrusion that engages with an opening formed in the column is formed on the contact surface of the horizontal beam mounting bracket main body. The interval between the protrusions is widened by inserting the transverse beam between the transverse beam mounting bracket main bodies, and the lower surface of the transverse beam mounting bracket main body is formed to be inclined downward toward the abutting surface side. The tip of the tube is bent outward along the contact surface, and the contact surface closes one end of the transverse beam mounting bracket body and is concave so as to be in close contact with the outer peripheral surface of the support column. It is characterized by being formed .

  According to the present invention, by providing a protrusion on the contact surface of the horizontal beam mounting bracket main body with the support and engaging the protrusion with the opening formed in the support, the horizontal beam can be temporarily placed and the horizontal beam can be placed. The horizontal beam mounting bracket can be attached to the column without using the fixing bolt for the mounting bracket. As a result, it is possible to easily attach the lateral beam to the support column, to improve the appearance, and to reduce the cost.

  One embodiment of the horizontal beam mounting bracket for a protective fence according to the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view showing a state in which a horizontal beam is attached to a column by a horizontal beam mounting bracket for a protective fence according to the present invention, and FIG. FIG. 3 is a side view showing a state in which a horizontal beam is attached to the column by the protective fence horizontal beam mounting bracket of the present invention, and FIG. 4 is a column of the protective fence horizontal beam mounting bracket of the present invention. FIG. 5 is a perspective view showing a state after the lateral beam is attached to the column by the protective fence transverse beam mounting bracket of the present invention.

  As shown in FIG. 1 to FIG. 5, a horizontal beam mounting bracket C (hereinafter simply referred to as a horizontal beam mounting bracket C) for a guard fence according to the present invention includes a pair of symmetrical horizontal beam mounting bracket bodies 1 a and 1 b. It has become. Each of the transverse beam mounting metal bodies 1a and 1b has a shape in which a tubular body having a contact surface 4 with a support 2 made of a round pipe attached to the transverse beam 3 at one end is halved. The outer diameter of the transverse beam 3 is the distance (L) between the transverse beam mounting bracket bodies 1a and 1b when the transverse beam 3 is inserted between the transverse beam mounting bracket bodies 1a and 1b temporarily fixed to the column 2 (see FIG. 1, 3, and 4) have dimensions to expand.

The contact surface 4 is formed so as to close one end of the transverse beam mounting metal bodies 1a and 1b, and is formed in a concave shape because the support column 2 is made of a round pipe. When the support column 2 is formed of a square pipe, the contact surface 4 is planar.

  Cutouts 5 are formed in the upper corner portions of the horizontal beam mounting metal bodies 1a and 1b. The reason why the notch 5 is formed is that when the horizontal beam 3 is temporarily placed on the horizontal beam mounting bracket body 1a, 1b after the horizontal beam mounting bracket body 1a, 1b is temporarily fixed to the column 2, as will be described later. This is because it is easy to insert the end portion of the transverse beam 3 into the transverse beam mounting bracket main bodies 1a and 1b. The lower surfaces of the horizontal beam mounting bracket main bodies 1a and 1b are formed to be inclined downward toward the contact surface 4 side. The reason why the lower portions of the horizontal beam mounting bracket main bodies 1a and 1b are formed to be downwardly inclined toward the abutting surface 4 is that the above-described effects due to the formation of the notches 5 in the horizontal beam mounting bracket main bodies 1a and 1b. This is because the end portion of the transverse beam 3 is easily inserted into the transverse beam mounting bracket main bodies 1a and 1b by a synergistic effect.

  Bolt holes 7 through which the transverse beam mounting bolts 6 for attaching the transverse beam 3 to the transverse beam attaching metal bodies 1a, 1b are inserted are formed on the side surfaces of the transverse beam attaching metal bodies 1a, 1b.

  On the abutment surface 4 of the horizontal beam mounting bracket main body 1a, 1b, a projection 9 is formed that engages with an opening 8 formed in the support column 2 and whose tip is bent outward. Further, when the horizontal beam mounting bracket main bodies 1a and 1b are brought into contact with (combined with each other), the protrusion 9 has a slightly smaller distance between the tips than the opening 8 formed in the column 2 (-1 to-). 2 mm). Accordingly, when the tip of the protrusion 9 is inserted into the opening 8 formed in the support column 2, the tip of the protrusion 9 engages with the opening 8. Therefore, as in the conventional mounting brackets A and B, the horizontal beam mounting bracket main body 1a. The fixing bolt which fixes 1b to the support | pillar 2 becomes unnecessary.

  In order to attach the transverse beam 3 to the column 2 by the transverse beam mounting bracket C, the following is performed.

  The transverse beam mounting bracket main bodies 1a and 1b are brought into contact with each other, and the protrusion 9 is inserted into the opening 8 formed in the column 2 so that the horizontal beam mounting bracket main bodies 1a and 1b are temporarily fixed to the column 2. At this time, the abutment surface 4 of the transverse beam mounting bracket C abuts on the column and the tip of the projection 9 is bent outward, so that the projection 9 engages with the opening 8. Further, since the movement of the horizontal beam mounting bracket C is restricted by the contact surface 4 of the horizontal beam mounting bracket C coming into contact with the column, the horizontal beam mounting bracket main bodies 1 a and 1 b are not detached from the column 2. .

  Next, the distal end of the transverse beam 3 is inserted between the transverse beam attachment fitting main bodies 1a and 1b from above the transverse beam attachment fitting main bodies 1a and 1b, and the transverse beam 3 is temporarily placed on the transverse beam attachment fitting main bodies 1a and 1b. By inserting the tip of the horizontal beam 3 between the horizontal beam mounting bracket main bodies 1a and 1b, the interval (L) between the horizontal beam mounting bracket main bodies 1a and 1b is widened. And the bent tip of the protrusion 9 engages with the opening 8 of the column 2 without rattling. As a result, the transverse beam mounting bracket main bodies 1 a and 1 b are firmly fixed to the support column 2.

  Moreover, since the horizontal beam 3 can be temporarily placed on the horizontal beam mounting bracket main bodies 1a and 1b, the horizontal beam 3 can be easily attached to the support column 2. The horizontal beam 3 is temporarily placed with notches 5 formed in the upper corners of the horizontal beam mounting bracket main bodies 1a and 1b, and the lower surfaces of the horizontal beam mounting bracket main bodies 1a and 1b facing the contact surface 4 side. Since it is formed in the downward slope, it can be easily performed.

  Next, the horizontal beam mounting bolt 6 is inserted into the horizontal beam mounting bracket main bodies 1 a and 1 b and the bolt hole 10 of the horizontal beam 3 and fixed by the nut 11.

  As described above, the transverse beam 3 can be attached to the support column 2 by the transverse beam mounting bracket C.

  As described above, according to the present invention, the horizontal beam mounting bracket main bodies 1a and 1b can be mounted on the support column 2 only through the projections 9, and the horizontal beam 3 can be mounted on the horizontal beam mounting bracket main bodies 1a and 1b. Since the horizontal beam 3 can be easily attached to the support column 2 and a fixing bolt for fixing the horizontal beam mounting bracket main bodies 1a and 1b to the support column 2 is not required, the appearance is excellent. In addition, the cost can be reduced.
