Description

  The present invention relates to a position adjustment jig.

  At present, a solar car port equipped with a solar panel to enable power generation has been proposed. When constructing a foundation structure of such a solar car port, if reinforced concrete is adopted as in the foundation structure of a building, complicated work such as processing of rebar, assembly of a form, dismantling of a form occurs. Had a problem of protracted

  Therefore, in recent years, square steel pipes are fixed to the upper ends of at least two piles driven into the ground, long H-shaped steels are disposed above these square steel pipes, and a plurality of bolts and nuts are used. A technique has been proposed in which a square steel pipe is connected to an H-shaped steel, and concrete is cast on the outside of a pile, a square steel pipe and an H-shaped steel to form a foundation structure (see, for example, Patent Document 1). By adopting this technology, it is possible to omit work such as processing of reinforcing bars, and construction in a short construction period becomes possible.

JP, 2016-44495, A

  By the way, even if the technique described in Patent Document 1 is adopted, the following complicated operations still remain. That is, in order to connect the square steel pipe to the H-shaped steel, first, the center point O is scored on the upper plate portion 110 of the square steel pipe 100 as shown in FIG. After the allocation (positioning) operation from point O, the fixing positions of the plurality of bolts B (the fixing positions in the long holes 120 of the square steel pipe 100) are determined, and the bolts B are fastened with the nuts N at the fixing positions. Thereafter, as shown in FIG. 10, each bolt B was inserted through the insertion hole 211 of the H-shaped steel 200, and the square steel pipe 100 was connected to the H-shaped steel 200 using the nut N. For this reason, there were cases in which the bolt B was difficult to insert into the insertion hole 211 of the H-shaped steel 200 depending on the inclination of the pile and the misalignment of the pile. Further, depending on the degree of deviation, it is necessary to loosen the bolt B, so a relatively large number of workers (at least three) are required.

  The present invention has been made in view of the above circumstances, and an H-shaped steel is disposed above a square steel pipe fixed to the upper end of a pile driven into the ground, and a plurality of bolts are used to make the square steel pipe H An object of the present invention is to significantly reduce the time and labor required for bolt positioning work when connecting mold steels.

  In order to achieve the above object, the positioning jig according to the present invention fixes square steel pipes to the upper ends of at least two piles driven into the ground, and arranges an H-shaped steel above the square steel pipes, When connecting an H-shaped steel to a square steel pipe with a plurality of bolts and nuts inserted through the elongated holes formed in the upper plate portion of the rectangular steel pipe and the insertion holes formed in the lower plate portion of the H-shaped steel, A first member having a plurality of bolt supports for supporting the plurality of bolts in an upright state, and a second member for supporting the first member from below A plurality of bolts inserted from the upper side of the long hole of the rectangular steel pipe supported in a state of being erected by the bolt support portion of the first member, and the second member The first member is configured to slide inside the square steel pipe in a supported state. Those which are.

  When this configuration is adopted, each of the plurality of bolts inserted from the upper side of the long hole of the rectangular steel pipe is supported in a state of being erected by the bolt supporting portion of the first member, and the second member In the supported state, the first member can be slid inside the square steel pipe. Therefore, when performing positioning in order to insert a bolt in the penetration hole of H type steel, a plurality of bolts can be moved collectively without changing relative physical relationship between a plurality of bolts. Conventionally, through the allocation (positioning) operation from the center point, the fixing position in the long hole of a square steel pipe of a plurality of bolts is determined, and each bolt is fastened to the fixing position in the insertion hole of H-shaped steel. Since it had been inserted, there were cases in which it was difficult to insert the bolt into the insertion hole of the H-shaped steel depending on the inclination of the pile and the misalignment of the pile core. However, by using this jig, it is not necessary to perform scribing work of the central point and allocation work from the central point conventionally performed at the time of positioning of the bolt, thereby significantly reducing the time and labor required for the positioning operation. be able to. In addition, by using this jig, it is not necessary to fasten each bolt to the long hole of the square steel pipe, and therefore, there is no need to loosen the bolt, which has conventionally been required when misalignment occurs. From this point as well, the positioning operation can be simplified (for example, the operation conventionally performed by three persons can be performed by two persons). In addition, even when fine adjustment is required due to the inclination of the pile or misalignment of the pile, sliding the first member inside the square steel pipe has the advantage of facilitating such fine adjustment.

  In the position adjusting jig according to the present invention, a first member having a plate-like portion can be employed. In such a case, a plurality of recesses provided in the plate-like portion can be adopted as a bolt support portion so as to support the respective bolts in an erected state by fitting the heads of the plurality of bolts. At this time, four recesses can be provided to correspond to the four bolts.

  Adopting such a configuration allows each bolt to be easily supported with a simple configuration (recess provided in the plate-like portion).

  In the position adjusting jig according to the present invention, a first member having a gripping portion gripped by a user can be employed.

  With this configuration, the user can grip the grip portion, so that the first member can be easily slid inside the square steel pipe. Therefore, fine adjustment becomes easy.

  In the position adjusting jig according to the present invention, a plurality of members (for example, two plate members having the same shape and having a predetermined height) can be adopted as the second member.

  When such a configuration is adopted, another member (for example, a bolt for fastening the upper end of the pile and the lower plate portion of the square steel pipe) exists below the vicinity of the widthwise central portion of the first member. Also, the second member (plural members) can be disposed below the both widthwise end portions of the first member to support the first member from below so as to avoid the member.

  According to the present invention, the H-shaped steel is disposed above the square steel pipe fixed to the upper end of the pile driven into the ground, and when connecting the H-shaped steel to the square steel pipe using a plurality of bolts, It is possible to significantly reduce the time and effort required for the positioning operation.

By adopting a plurality of members in this manner as the second member 20, as shown in FIG. 5, another member (the upper end of the pile P and the square steel pipe 100) is provided in the lower part near the widthwise center of the first member 10. Even if there is a bolt B) for fastening the lower plate portion 130, the second member 20 is disposed below the vicinity of both widthwise ends of the first member 10 so as to avoid that member. Thus, the first member 10 can be supported from below.

  Next, a method of using the position adjusting jig 1 according to the present embodiment will be described with reference to FIGS.

  First, the second members 20 (two plate members 21) of the position adjusting jig 1 are inserted into the square steel pipe 100 and arranged. At this time, as shown in FIG. 5, the two plate members 21 are erected so as to sandwich the bolt B for fastening the upper end of the pile P and the lower plate portion 130 of the square steel pipe 100. Next, as shown in FIGS. 5 and 7, the first member 10 is placed above the second member 20, and the first member 10 is supported by the second member 20 from below. Subsequently, as shown in FIG. 5 to FIG. 7, each of the plurality of bolts B inserted from the upper side of the long hole 120 of the square steel pipe 100 is supported by the bolt support portion 11 of the first member 10. .
