Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reinforcing member used for an H-shaped pile.

[0002]

[Prior Art]

 When the conventional H-shaped pile was placed in the ground at the construction site, it was deformed due to resistance due to stones, bedrock, soil, earth pressure, etc. existing in the ground, and the flange was sometimes deformed. As a result, the gaps between the grips were widened due to the inward deformation of the flanges formed at the ends, which narrowed the gap between the grips, and the expanded deformation of the flanges. In addition, the web deformed and the distance between the flanges narrowed, and the H-shape of the pile collapsed. This deformation was particularly remarkable at the tip portion. When the H-shaped piles are driven in such a deformed state, there are drawbacks such as that they cannot be driven vertically or they cannot be driven in a straight line, and the resistance when driving is increased.

[0003]

[Problems to be solved by the device]

 The conventional H-shaped pile consists of a web and a flange, and since the flange part with the highest resistance to driving is not provided with reinforcing means, when driving at the construction site, stones and rocks existing in the ground However, there was a problem that the resistance H shape was destroyed by deformation due to resistance due to soil quality, earth pressure, etc. According to the present invention, the H-shaped pile is reinforced by the reinforcing member so that the H-shaped pile can be driven vertically or linearly without being easily deformed even if it receives resistance. It is intended to provide a reinforcing plate for piles.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is characterized in that a steel member is processed to form a reinforcing member, and the reinforcing member is attached to the flange of the H-shaped pile or the web and the flange. Alternatively, it is characterized in that the steel material is bent at the central portion, both ends are fixed to the inside of the flange, and the bent portion is fixed to the web. Alternatively, it is characterized in that a steel material is bent to form a triangular shape and each corner is fixed to a web and a flange. Alternatively, it is characterized in that the frame-shaped member is made of steel and the X-shaped member is fixed to each corner of the frame-shaped member. As described above, the reinforcing member of the present invention has various shapes, but basically, the triangular shape or a combination thereof is advantageous in terms of strength.

[0005]

[Action]

 When the H-shaped pile with the reinforcing member attached to the flange or the web and the flange as described above is driven into the ground, the H-shaped pile causes resistance due to the stone, rock, soil, earth pressure, etc. existing in the ground. It does not easily deform even if it receives it, and it can be placed vertically or smoothly in a straight line.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 is an H-shaped pile, reference numeral 2 is a web, reference numeral 3 is a flange, reference numeral 4 is a grip, reference numeral 5 is a reinforcing member, reference numeral 6 is a welding portion, reference numeral 7 is a mounting piece, and reference numeral 8 is a step portion. In the first embodiment shown in FIG. 1, a reinforcing member 5 made of steel material formed in a V shape between the flanges 3 is provided with a bent portion on the web 2 and each tip portion on an inner portion of the flange 3. It is abutted against and fixed at the abutting point by welding. Although the reinforcing member 5 is provided on one side in the first embodiment shown in FIG. 1, the reinforcing member 5 may be provided on both sides as shown in FIG. Further, the fixing of the abutting portion and the reinforcing member in other embodiments is not limited to welding but may be fixing means such as bolts. In the second embodiment shown in FIG. 3, the reinforcing member 5 is formed in a triangular shape, and its corners are welded to the web 2 and the flange 3 for reinforcement. Of course, this reinforcing member is used for the web 2 It may be provided on both sides of.

In the third embodiment shown in FIG. 4, a reinforcing member 5 composed of a quadrilateral frame 11 and a reinforcing member 12 formed in an X shape is abutted on the flange 3 on two sides thereof to form the frame 11 Each corner of the is welded and fixed. The two sides of the reinforcing member 5 that come into contact with the flange 3 may be extended to expand the frame shape 11 to reinforce the vicinity of the web 2. Further, the reinforcing members 5 of the frame shape 11 may be provided on both sides of the web 2. It may be provided. The fourth embodiment shown in FIG. 5 is one in which each corner of the K-shaped reinforcing member 5 is brought into contact with the web 2 and the flange 3 and the abutting portions are welded. You may provide the reinforcement member 5 on both sides of 2.

In the fifth embodiment shown in FIG. 6, each end portion of the reinforcing member 5 formed in an X shape is brought into contact with the flange 3 and each contact portion is welded, and in this case as well. Reinforcing members 5 may be provided on both sides of the web 2. In the sixth embodiment shown in FIG. 7, each end portion of the reinforcing member 5 including the reinforcing member 13 formed in an I shape and the reinforcing member 14 formed in the shape of a quadrangle is connected to the web 2 and the flange 3 respectively. In this case, the reinforcing members 5 may be provided on both sides of the web 2.

The reinforcing member 5 may be attached to the H-shaped pile by providing it at the tip of the H-shaped pile or at an appropriate place as necessary. Further, as shown in FIG. A plurality of 5 may be provided. Furthermore, when attaching the reinforcing member 5 including the quadrilateral frame shape 11 of the third embodiment shown in FIG. 4 and the reinforcing member 12 formed in the X shape to the tip of the H-shaped pile, As shown in FIG. 8, the upper ends of the two opposite sides of the quadrilateral frame are extended to form a mounting piece 7, and the reinforcing member made of the quadrilateral frame is fitted to the tip of the H-shaped pile to form the mounting piece. 7 may be brought into contact with the flange 3 and then welded or fixed and tightened with bolts and nuts 9.

Further, as shown in FIG. 9, when a step portion 8 is formed when the upper ends of two opposite sides of the quadrilateral frame are extended to form the mounting piece 7, the step portion 8 is an H-shaped pile. When the H-shaped pile is driven into the ground, the reinforcing member will come off from the tip of the H-shaped pile even if the welding location or the fixing or tightening with bolts and nuts 9 is removed. Never.

Although the reinforcing member 5 shown in FIG. 9 is formed by mounting the mounting piece 7 along the outside of the flange 3, the reinforcing member's mounting piece 7 is arranged along the inside of the flange 3 as shown in FIG. If formed in this manner, the flange 3 and the reinforcing member 5 are flush with each other, so that when the H-shaped profile is struck in the ground, the friction resistance is reduced and the slab can be smoothly struck.

When the reinforcing member 5 of the present invention is attached to the H-shaped pile, when the hydraulic press-fitting / extracting machine is used, the H-shaped pile can be attached on the spot after inserting the chuck. Also, when grasping at the top with a bilob, etc., it can be installed either at the factory or at the work site, so efficient installation work can be selected based on the work plan.

[0013]

[Effect of the device]

 Since the present invention is configured as described above, when the H-shaped profile is placed in the ground at the construction site, the H-shaped profile is formed due to the stone, rock, soil, earth pressure, etc. existing in the ground. The pile can be driven vertically and in a straight line without being deformed due to resistance and the H-shape of the pile is not destroyed. In addition, the increase of the resistance force due to the driving due to the deformation of the pile is small. Further, since the reinforcing member can be easily attached to the conventional H-shaped pile, there is no need to purposely manufacture a reinforced H-shaped pile, and the manufacturing cost can be reduced and it is economical. Furthermore, since the installation can be performed either at the factory or at the work site, efficient installation work can be performed based on the work plan, and work efficiency is improved.
