  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 front view showing a protective fence constructed by a horizontal beam mounting bracket for a protective fence according to the present invention. FIG. 2 shows the protective fence constructed by a horizontal beam mounting bracket for a protective fence according to the present invention obliquely from below. FIG. 3 is a front view showing one of the protective fence lateral beam mounting brackets according to the present invention, and FIG. 4 is a front view showing the other protective fence lateral beam mounting bracket according to the present invention.

  As shown in FIGS. 1 to 4, the horizontal beam mounting bracket C1 (hereinafter simply referred to as a horizontal beam mounting bracket C1) for a guard fence according to the present invention is formed by bending a steel plate as a plate material into a U-shape. A band portion 2 as a fixing portion fixed by being wound around 1 and a pair of transverse beam attachment portions 4 to which the transverse beam 3 is attached are formed.

  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 attaching portions 4 is formed with a bolt hole 7 through which the transverse beam attaching bolt 5 is inserted and a transverse beam temporary placing portion 8 in which the transverse beam 3 is temporarily placed.

  The horizontal beam temporary placement portion 8 includes an inner temporary placement portion 9 and an outer temporary placement portion 10 that are formed with an interval (T) (see FIG. 3). It is formed inside the lower part of the part 4. The height of the inner temporary placement portion 9 is formed higher than the height of the outer temporary placement portion 10. In FIG. 3, the difference in height is indicated by (H).

  In the illustrated embodiment, the horizontal beam temporary placement portion 8 is formed by bending the lower portion of the horizontal beam mounting portion 4 inward. However, the horizontal beam temporary placement portion 8 is manufactured separately and is formed as a horizontal beam. You may fix to the inner side of the lower part of the attachment part 4 by welding etc.

  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 11 that covers the top of the column 1. Between the upper band portion 2a and the lower band portion 2b, a band portion 2 of a transverse beam mounting bracket C2 (hereinafter simply referred to as a lateral beam mounting bracket C2) of the other guard fence of the present invention, which will be described later, is inserted. The

  Since the band portion 2 is integrated with the cap 11, a fixing bolt for the horizontal beam mounting bracket for fixing the horizontal beam mounting bracket C1 to the support column 1 is not required, and positioning of the horizontal beam mounting bracket C1 is ensured. It can be done.

  The other lateral beam mounting bracket C2 does not move up and down because the band portion 2 is inserted between the upper band portion 2a and the lower band portion 2b of the one lateral beam mounting bracket C1. 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. 4, the above-mentioned one horizontal beam mounting bracket C1 and the other horizontal beam mounting bracket C2 mounted on the opposite side across the support column 1 have a band portion 2 having an upper band portion 2a and a lower band portion 2b. It is different from one of the protective fence lateral beam mounting brackets C1 only in that it is not divided into two (see FIG. 4).

  In order to attach the transverse beam 3 between the columns 1 with the one and the other transverse beam fittings C1 and C2, the following is performed.

  The band portion 2 of one horizontal beam mounting bracket C1 and the band portion 2 of the other horizontal beam mounting bracket C2 sandwiched between the upper band portion 2a and the lower band portion 2b are fitted from the upper end of the column 1. Since the upper band portion 2a and the cap 11 of the support column 1 are integrated, if the band portion 2 of one and the other lateral beam mounting brackets C1 and C2 is fitted into the support column 1, the cap 11 is automatically attached to the support column 1. The one and the other lateral beam mounting brackets C1 and C2 are securely mounted at predetermined positions on the support column 1 without using the fixing bolts for the horizontal beam mounting brackets.

  Next, the end of the transverse beam 3 is temporarily placed on the transverse beam temporary placement portion 8 of the transverse beam mounting brackets C1 and C2 of the support column 1.

  When the transverse beam 3 is temporarily placed, as shown in FIG. 7A, when the distance (L) between one strut 1a and the other strut 1b is a reference distance, the transverse beam 3 is attached to the transverse beam. Although there is no risk of falling off the horizontal beam temporary placement portion 8 of the metal fittings C1 and C2, as shown in FIG. 7B, when the interval between the support columns 1a and 1b is longer than the reference interval by (L1) due to construction errors. For example, when one end of the horizontal beam 3 is brought into contact with one of the columns 1a, the other end of the horizontal beam 3 falls off from the horizontal beam temporary mounting portion 8 of the horizontal beam mounting bracket C2 of the other column 1b. There is a fear.

  In this case, as shown in FIG. 7C, one end portion of the horizontal beam 3 is temporarily placed on the outer temporary placement portion 10 of the horizontal beam mounting bracket C1 of one of the columns 1a (in FIGS. 5 and 6). See left side). The height of the inner temporary placement portion 9 is formed higher than the height of the outer temporary placement portion 10, and the inner temporary placement portion 9 is separated from one of the columns 1a. It contacts the inner temporary placement part 9. As a result, the other end portion of the transverse beam 3 can be surely temporarily placed on the transverse beam temporary placement portion 8 without dropping from the transverse beam temporary placement portion 8 of the other column 1b. In the example shown in FIG. 7C, the other end portion of the horizontal beam 3 can be temporarily placed on the outer temporary placement portion 10 of the horizontal beam temporary placement portion 8 of the other column 1b.

  When the horizontal beam 3 is tilted between the columns 1 and attached, for example, one end of the horizontal beam 3 is temporarily inclined to the temporary setting part 7 of the horizontal beam mounting bracket C2 of one column 1a. When the interval between the columns 1a and 1b is longer than the reference interval, the lower part of one end of the horizontal beam 3 is hooked in the gap (S) between the inner temporary holder 9 and the outer temporary holder 10 (FIGS. 5 and 6). Middle, see right). As a result, even if the interval between the columns 1a and 1b is longer than the reference interval, the transverse beam 3 can be tilted and reliably placed between the columns 1.

  After the horizontal beam 3 is temporarily placed between the columns 1 in this way, the horizontal beam 3 is fixed between the columns 1 by inserting the horizontal beam mounting bolt 5 into the bolt hole 7 and fixing it with a nut (not shown). Can be easily attached to.

  As described above, according to the present invention, the transverse beam 3 can be easily attached to the column 1 by forming the transverse beam temporary placing portion 8 in the transverse beam attaching portion 4.

  Further, according to the present invention, the horizontal beam temporary placement portion 8 is configured by the inner temporary placement portion 9 and the outer temporary placement portion 10 having different heights, so that the interval between the support columns 1 is larger than the reference interval due to construction errors. Even if it is long, the horizontal beam 3 can be temporarily placed on the horizontal beam temporary placement portion 8 without fail regardless of the mounting angle of the horizontal beam 3 with respect to the column 1.

  In addition, according to the present invention, the fixing portion fixed to the support column 1 is formed by the band unit 2 wound around the support column, and the band unit 2 and the cap 11 of the support column 1 are integrated, so that Since the transverse beam mounting bracket can be attached to the support column 1 without using a fixing bolt, the attachment of the transverse beam 3 to the support column 1 can be easily performed, the appearance is excellent, and the cost can be reduced. .
