Description

[Detailed description of the present invention] (a) Industrial application field The present invention relates to a guide for building a retaining wall steel material used when a supporting steel material such as an H-section steel is built in a continuous hole drilled in the ground.

(B) Conventional technology Conventionally, when forming a retaining wall containing steel columns, first, a continuous hole is drilled in the ground using an earth auger, and holes 1, 3, and 5 are respectively formed as shown in FIG. H-section steel columns
1a, 5a are built, and then the long ruler 6 of the L-shaped steel is applied to the side surfaces of these support steels, the support steels 1a, 5a are built, and then the support steels 1a, 5a and the long ruler 6 are attached. It is fixed with separate clamp-type fasteners B1 and B1, the column steel members 1a and 5a are erected, and the column steel members 2a and 4a (the fourth (Refer to the figure).

(C) Problems to be solved by the invention In the conventional example, the long ruler 6 of the clamp type is separated from the long ruler 6 of the clamp type, so that the long ruler 6 can be separated from the supporting steel. When mounting and removing, tighten
B1 may fall into the hole, so that several replacement fasteners must always be prepared, which is extremely uneconomical and inefficient in handling when attaching and detaching. The present invention is intended to solve the drawbacks of the conventional example, and does not lose the fasteners attached to the long ruler material, so that it can be conveniently handled when fixing the long ruler material to the H-section steel. An object of the present invention is to obtain a guide for building a steel retaining wall.

D. Means for Solving the Problems As shown in FIGS. 1 and 2, the present invention provides a clamp-type fastening tool having a fastening screw 7 for holding a supporting steel member 1a on one leg 8a. When B is provided at both ends of the long ruler member 6, a slider 10 movable along the longitudinal direction is provided on the long ruler member so as not to fall off, and tightening of the slider and the fastener is performed. The leg 8b on the side without the screw 7 is connected by a pin 10a, and
Is a rock retaining wall steel guide for forming a retaining wall wall in which a space is formed between the long ruler member 6 and the tightening screw 7 so that the supporting column steel member 1a can be inserted therebetween. .

E Action In FIG. 4, A is a retaining wall, and continuous column holes 1 to 5 mm.
Injecting cement milk into each hole and supporting H-section steel 1a
~ 5a ‥ built. In constructing the retaining wall A, cement milk is poured while drilling the holes 1 to 5 using an earth auger, and first, the strut steel materials 1a, 3a, 5a are respectively inserted into the holes 1, 3, and 5. Stand up. The fastening tool B is centered on a pin 10a connecting the slider 10 movably attached along the longitudinal direction of the long ruler member 6 and the leg 8b of the fastening tool B on the side where the fastening screw 7 is not provided. Since the fastener B swings and a space is formed between the long ruler member 6 and the tightening screw 7 so that the column steel member 1a can be sandwiched between the long ruler member 6 and the tightening screw 7, the long ruler member 6 is connected to the column steel member 1a, 3a, 5a. The flanges f of the supporting steel members 1a and 5a are put in the same space, and the tightening screws 7 are turned. The long ruler 6 is fixed to the supporting steel members 1a by the tightening tool B as shown in FIG. , 5a. At this time, support steel materials 1a, 5a
When the position of the flange portion f does not match the position of the fastener B, the slider 10 is moved along the long ruler member 6 to adjust the position of the fastener B to clamp the flange portion f. Then, using the long ruler member 6 as a guide, the column steel members 2a and 4a are built in the holes 2 and 4 respectively. When this step is completed, the fastening screw 7 is loosened, the fastening tool B is removed from the column steel materials 1a and 5a, and the same operation is performed thereafter to complete the entire retaining wall A. Since the fastener B is attached to the long ruler member 6, it does not fall into the hole when the fastener B is attached to or detached from the steel column.

(C) Embodiment One embodiment of the guide for building a retaining wall steel material according to the present invention will be described with reference to FIGS. 1 and 2. FIG. B is a clamp-type fastening tool provided at both ends of the long ruler member 6. Reference numeral 8 denotes a main body of the tightening tool. A tightening screw 7 with a handle 7a is screwed inward on the long leg 8a. Reference numeral 9 denotes a lip-shaped guide frame fixed along the longitudinal direction to the back of one side of the long ruler member 6 made of L-shaped steel. The ruler 6 can be moved along the longitudinal direction. 10a is the handle 9 of the slider 10
a pin connecting the lower end of the leg 8b on the side of the main body 8 where the tightening screw is not provided, so that the long ruler 6 can swing, and the lower part is opened to open an opening between the leg 8a and the leg 8a. Form 11. The position of the pin 10a is provided substantially opposite to the traveling direction of the tightening screw 7. 7b is a seat plate at the inner end of the tightening screw 7 protruding from the leg 8a to the opening 11. This seat plate is not required. The upper end of the flange portion f of the supporting steel members 1a, 5a is inserted into the space between the inner end (the seat plate 7b) of the tightening screw 7 and the long ruler member 6, and the tightening screw 7 is inserted as shown in FIG. When the screw is advanced, the long ruler member 6 comes into contact with the flange portion f, and the flange portion f is sandwiched between the screw end and the long ruler member 6, and as shown in FIG. The member 6 is fixed to the column steel members 1a and 5a. Therefore, another pillar steel material can be aligned and built in the hole between the pillar steel materials 1a and 5a using the long ruler 6 as a guide.

(G) Effects of the present invention The present invention provides a clamp-type tightening tool B having a tightening screw 7 for holding the supporting steel member 1a on one leg 8a.
When providing at both ends of the long ruler material 6,
A slider 10 movable along the longitudinal direction is provided so as not to fall off, and the slider is connected to a leg 8b of the fastener without the fastening screw 7 by a pin 10a. Since the ruler is swingable with respect to the fastener B and a space is formed between the ruler 6 and the tightening screw 7 so that the supporting steel member 1a can be sandwiched between the ruler B and the fastening ruler B. In this case, the fastener B does not fall into the hole and is lost, and the position of the fastener B can be adjusted by moving the fastener B, so that the long ruler and the fastener can be efficiently handled in a lump.
