In addition, it is preferable that the cross rail having the upper rail and the lower rail extending in the longitudinal direction and the end plate that covers the end surface of the horizontal rail be provided.

[0006]

The feature of the present invention is that the lattice member is provided with the upper and lower bars and the standing piece softly attached to the engaging piece inserted into the upper and lower bars, and the angle between the upper and lower bars and the standing piece is adjustable. Since the engaging piece is attached to the side in the direction in which a plurality of columns are arranged side by side, as in the conventional example, according to the inclination angle of the stairs, etc. It is not necessary to cut it into pieces, and it is sufficient to cut it into a predetermined length at a right angle. Hereinafter, the operation of the present invention will be described according to the claims. As for the invention of the method of the present invention, in the method for mounting a variable lattice member for civil engineering construction, wherein a variable tilt type lattice member having a standing member and a horizontal rail is mounted on a support, an engaging piece is rotatably attached to the standing member. And a step of inserting the engaging piece into a horizontal rail formed by extending in the longitudinal direction, the variable tilt type lattice member is assembled, and the horizontal rail with respect to the standing member is set at a predetermined angle to the standing member or / and the It comprises a step of rotationally adjusting the cross rail and a step of fixing the end of the engaging piece to the side of the column.

However, it is possible to deal with any setting of the inclination angle of the stairs. Then, by fixing the ends of the engaging pieces to the support columns, a lattice that matches a predetermined angle is attached.

[0007] Further, the grid member includes a step of softly attaching the first engaging piece to the standing piece so as to be rotatable and a step of inserting the first engaging piece into a cross rail formed by extending in a longitudinal direction. And assembling the second engaging piece to the side of the column, and contacting the end of the first engaging piece inserted into the horizontal rail to attach the second engaging piece. And a step of inserting it into the end of the horizontal rail, instead of fixing the end of the engaging piece to the support, the second engaging piece provided on the support is attached to the side. By inserting it into the end of the crosspiece, a lattice conforming to a predetermined angle is attached.

[0008] Further, a step of rotatably attaching the first engaging piece to the standing piece, and a pitch interval between the first engaging piece and the standing piece are determined in a horizontal rail formed by extending in the longitudinal direction. Assembling the variable tilt grid member by alternately inserting the space engaging pieces, and softly attaching the second engaging piece to the side surface of the column, and the first inserting in the cross rail. And a step of inserting the second engaging piece into an end portion of the horizontal rail by abutting on an end of the engaging piece or the interval engaging piece, Since the first engaging pieces and the spacing engaging pieces are alternately inserted, if a plurality of dimensions of the spacing engaging pieces are prepared, it is possible to cope with different standing pitches, and the pitch of the predetermined spacing is increased. Rather than prepare a long first engaging piece provided with an engagement hole with the standing piece and cut it to a predetermined length,
It suffices to store the short first engagement piece and the short engagement piece, and since the first engagement piece is softly attached to the stand, the stand can be folded and stored, so the storage space is reduced.

The invention of this mechanism is a variable tilt type lattice mechanism for civil engineering construction, which has a standing member and a horizontal rail and is attached to a column,
An engaging piece rotatably provided on the standing piece for adjusting the angle between the standing piece and the horizontal crosspiece; the horizontal crosspiece formed by extending in the longitudinal direction to insert the engaging piece; And a column having laterally a holding portion for holding the end portion of the engaging piece. Therefore, the angle between the standing beam and the cross rail is freely adjusted by the engaging piece softly attached to the standing plate,
It is not necessary to prepare many kinds of lattice members according to the inclination angle of the stairs, and it is possible to cope with any setting of the inclination angle of the stairs. Then, by fixing the ends of the engaging pieces to the support columns, a lattice that matches a predetermined angle is attached.

Further, in order to adjust the angle between the standing member and the horizontal crosspiece, a first engaging piece rotatably provided on the standing member and extending in the longitudinal direction are formed. In order to adjust the angle between the cross rail into which the joint piece is inserted and the post and the cross rail, it is rotatably provided on the side of the post,
In the case of being configured with a second engaging piece that comes into contact with the end of the first engaging piece that is inserted into the cross rail, the end portion of the engaging piece is provided on the supporting column instead of being fixed to the supporting column. By inserting the obtained second engaging piece into the end portion of the cross rail, a lattice conforming to a predetermined angle is attached.

[0011] Further, a space engaging piece which is inserted into the horizontal rail alternately with the first engaging piece and determines a pitch of the standing member,

And a second engaging piece that comes into contact with the second engaging piece, the first engaging piece and the interval engaging piece are alternately inserted into the horizontal rail, and thus the interval engaging piece is inserted. If you prepare multiple dimensions of the joint piece, you can accommodate different standing pitches, prepare a long first engaging piece with engaging holes for standing pieces at a pitch of a predetermined interval, and cut it to a predetermined length. The storage space can be reduced because the shorter first engagement piece and the shorter engagement piece need only be stored as compared with the case of using the same.

Further, in the case where it is constructed by including the horizontal rail formed by extending in the longitudinal direction and having an upper rail and a lower rail, and an end plate which covers the end surface of the horizontal rail, Since the end plate is covered at the end portion of the horizontal rail, the end plate is locked by the engaging piece provided on the column, and even if the horizontal rail is inclined, the end plate does not fall off by its own weight.
