  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.

  According to the first aspect of the present invention, in the transverse beam mounting bracket for a protective fence for attaching a transverse beam to a support, a band portion wound around the support and the transverse beam are attached by bending a plate material into a U shape. A pair of transverse beam attachment portions is formed, and each of the transverse beam attachment portions is formed with a temporary placement portion of the transverse beam and a bolt hole through which the transverse beam attachment bolt is inserted, and the band portion is The temporary placing portion is integrated with the cap of the support column, and the temporary placement portion includes a support material insertion opening formed at a lower portion of the horizontal beam attachment portion, and a support material that can be inserted into the support material insertion opening. It has a feature in being.

  According to the present invention, the horizontal beam can be easily attached to the support column by forming the horizontal beam temporary placement portion in the horizontal beam attachment portion.

  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 partial plan view showing a protective fence constructed by a horizontal beam mounting bracket for a protective fence according to the present invention. FIG. 2 is a partial front view showing a protective fence constructed by a horizontal beam mounting bracket for a protective fence according to the present invention. 3 is a view as viewed from the direction of the arrow A in FIG. 1, FIG. 4 is a view as viewed from the direction of the arrow B in FIG. 1, and FIG.

  As shown in FIG. 1 to FIG. 4, 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 is formed by bending a steel plate as a plate material into a U shape. 1 comprises a band portion 2 wound around 1 and a pair of transverse beam attachment portions 4 to which a transverse beam 3 is attached. The transverse beam attaching portions 4 are formed in parallel to face each other, and the end portions of the transverse beams 3 are sandwiched between the transverse beam attaching portions 4 and fixed by the transverse beam attaching bolts 5. Reference numeral 6 denotes a reinforcing emboss.

  Each of the transverse beam attachment portions 4 is formed with a temporary placement portion 7 for the transverse beam 3 and a bolt hole 8 through which the transverse beam attachment bolt 5 is inserted.

  The temporary placement portion 7 is formed by bending the lower corner portion of the horizontal beam attachment portion 4 inward. By bending the lower corner portion of the transverse beam attachment portion 4 inward, the distance between the opposing transverse beam attachment portions 4 is narrower than the outer diameter of the transverse beam 3, so that the transverse beam 3 can be temporarily placed. In addition, since the transverse beam attaching portion 4 is formed by bending the lower corner portion inward, the interval between the opposing transverse beam attaching portions 4 is gradually formed downward. As a result, since the deviation and rotation of the transverse beam 3 between the transverse beam attachment portions 4 can be suppressed, the attachment of the transverse beam 3 to the column 1 can be easily performed.

  The band part 2 is divided into two parts, an upper band part 2 a and a lower band part 2 b, and the upper band part 2 a is integrated with a cap 9 that covers the top of the column 1. Between the upper band portion 2a and the lower band portion 2b, the band portion 2 of the other transverse beam mounting bracket C described later is inserted.

  Since the band portion 2 is integrated with the cap 9, a fixing bolt for the horizontal beam mounting bracket for fixing the horizontal beam mounting bracket C to the support column 1 becomes unnecessary, and positioning of the horizontal beam mounting bracket C can be performed. The Since the band part 2 is inserted between the upper band part 2a and the lower band part 2b of the one horizontal beam mounting bracket C, the other horizontal beam mounting bracket C does not move up and down. By eliminating the need for the fixing bolt for the horizontal beam mounting bracket, it is possible to easily attach the horizontal beam 3 to the support column 1 and to improve the appearance and to reduce the cost.

  As shown in FIG. 6, the above-mentioned one horizontal beam mounting bracket C and the other horizontal beam mounting bracket C mounted on the opposite side across the support column 1 are only in that the band portion 2 is not divided. It is different from the horizontal beam mounting bracket C for the protective fence (see FIG. 5).

  In order to attach the horizontal beam 3 to the support column 1 with the one and the other horizontal beam mounting bracket C, the band portion 2, the upper band portion 2a and the lower band portion 2b of the one horizontal beam mounting bracket C from the upper end of the support column 1 are connected. The band part 2 of the other horizontal beam mounting bracket C sandwiched between the two is fitted. Since the upper band portion 2a and the cap 9 of the support column 1 are integrated, the cap 9 is automatically put on the support column 1 when the band portion 2 of one and the other lateral beam mounting bracket C is fitted into the support column 1. The one and the other lateral beam mounting bracket C are mounted at predetermined positions of the column 1 without using the fixing bolt for the lateral beam mounting bracket.

  Next, the end of the transverse beam 3 is temporarily placed on the temporary placement portion 7 of the transverse beam mounting bracket C (see FIG. 2), and the transverse beam mounting bolt 5 is connected to the bolt hole 8 of the transverse beam mounting portion 4 and the bolt of the transverse beam 3. It is inserted into the hole 10 and fixed by the nut 11.

  As described above, the horizontal beam 3 can be attached to the support column 1 by the one and the other horizontal beam mounting bracket C.

  FIG. 7 shows another protective fence transverse beam mounting bracket C according to the present invention. This horizontal beam mounting bracket C is different from the above-described horizontal beam mounting bracket C only in the shape of the temporary placement portion 7 of the horizontal beam 3. The temporary placement portion 7 of the illustrated horizontal beam mounting bracket C is formed by bending the substantially central portion of the lower end of the horizontal beam mounting portion 4 in a mountain shape, and the temporary placement effect is the same as that of the horizontal beam mounting bracket C described above. It is the same.

  FIGS. 8A to 8C show another temporary placement unit. 8A to 8C, the same reference numerals as those in FIGS. 1 to 7 denote the same components.

  The temporary placement portion includes a support material insertion opening 12 formed in a lower corner portion of the transverse beam mounting portion 4 and a support material 13 that can be inserted into the support material insertion opening 12. As described above, by inserting the support member 13 into the opening 12, the transverse beam 3 can be temporarily placed, and the temporary placing portion 7 formed by bending a part of the transverse beam attaching portion 4 inward, Similar effects can be obtained.

  The support member 13 may be any tool that can support the own weight of the transverse beam 3 and can be inserted into the opening 12 such as a tool such as a screwdriver, a reinforcing bar, and wood.

  As described above, according to the present invention, the horizontal beam 3 can be easily attached to the support column 1 by forming the temporary placing portion 7 of the horizontal beam 3 in the horizontal beam attaching portion 4.

  Further, according to the present invention, the band portion 2 wound around the support column 1 and the cap 9 of the support column 1 are integrated, so that the horizontal beam mounting bracket C can be attached to the support column 1 without using the fixing bolt for the horizontal beam mounting bracket. Therefore, it is possible to easily attach the horizontal beam 3 to the support column 1 and to improve the appearance, and to reduce the cost.
