Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention constructs a mountain retaining wall in order to prevent the collapse of the surrounding ground during the construction of an underground skeleton. The present invention relates to a bracket member used to hold a main pile or a shelf pile at a predetermined position.

(Prior art) A mountain retaining wall is constructed in order to prevent the collapse of the surrounding ground during underground structure construction. This retaining wall is driven by H-shaped steel piles at appropriate intervals into the ground. Insert a horizontal sheet pile for retaining the soil between the piles and stretch it, and further attach a bulge to each parent pile on the side to be excavated, and install a cutting beam between each bulge and each parent pile. It is built to support the earth pressure on piles and sheet piles.

This uprising is attached by mounting it on the uprising bracket that is fixed to the main pile by welding at the required intervals, and the beam is connected to the opposite uprising at its both ends. It is placed on a shelving bracket that is fixed by welding to a shelf pile made of H-shaped steel that has been driven into the ground at some point and is erected.

(Problems to be solved by the invention) The brackets that hold upsets or beams are welded to parent piles or shelf piles, but you cannot take a welding machine with a too large capacity to the construction site. Therefore, there is a drawback that it takes a long time to weld the bracket and a lot of man-hours are required.

Also, many pile retaining materials such as main piles, side sheet piles, upsets, cut beams, and shelf piles used for underground construction work are leased and used repeatedly on many sides. Although it must be dismantled, the bracket will be an obstacle during the dismantling work, and eventually it must be melted and removed by gas etc., which requires a lot of man-hours and damage to the bracket. However, there is a drawback that it may not be reused.

(Means for Solving the Problem) The present invention has been made in view of the above-mentioned conventional problems, and has a simple structure and can be detachably attached to a parent pile or a shelf pile by bolting without welding. It is intended to solve the above-mentioned problems by dramatically improving the function of the bracket member by making it possible to mount it on the.

According to the present invention, a metal fitting body provided with a screw hole is provided with a U-shaped locking portion at one end thereof and a through hole or a bolt hole near the center, which is vertically provided at the other end opposite to the locking portion. A plurality of holding metal fittings having a holding portion provided with any of them; a holding hole is formed near one end, and a holding hole is formed near the lower end near the other end of a horizontal arm having a flat upper surface. A holding member having the upper end of the holding arm fixed at a required angle; one flange of the H-shaped steel of the pile, which is opposed from both sides and is fitted in two steps at predetermined intervals via the locking portion, and the screw hole is formed. Two pairs of the holding metal fittings fixed via the through-holes and the two-stage holding shafts having the tips fixed in the through-holes or the bolt holes; and the holding members at the centers of the holding metal fittings on both sides. A bracket characterized by being positioned and fixed by two pairs of the holding shafts through the holding holes of the both arms. It is a member.

Also, the present invention provides a metal fitting body provided with a screw hole, a U-shaped locking portion at one end thereof, and a through hole or a bolt hole near the center, which is provided at the other end so as to hang down to the opposite side of the locking portion. A plurality of holding metal fittings provided with a holding portion provided with any one of: a holding arm provided with a holding hole near one end and an outer end having a lower end vertically suspended at the one end near the other end of a horizontal arm having a flat upper surface. A holding member having an upper end of a holding arm fixed to a connecting arm having a flat surface fixed at a required angle; and fitted to one flange of the H-shaped steel of the pile from both sides via the locking portion, A pair of holding metal fittings fixed through the screw holes are holding shafts which are inserted through the through holes and whose ends are fixed in the through holes or bolt holes; the holding member is provided at the center of the pair of holding metal fittings. Is positioned and fixed by the holding shaft through the holding hole of the horizontal arm. A socket member.

(Operation) Since each part of the bracket member is attached to the H-shaped steel of the parent pile or the shelf pile by tightening the bolts, the attachment is easy and requires less work man-hours, and a welding machine and a welding engineer are required. Instead, it can be worn by low-techies.

Further, when the underground retaining wall construction is completed and the mountain retaining wall is dismantled, the bracket member can be easily removed, which does not require much man-hours.

Further, since the bracket member has a simple structure and can be attached and detached by tightening bolts, it is not damaged during its work and can be used much more repeatedly than the conventional one.

Next, the holding member 40 is positioned between the two holding fittings 31, 38, the holding shaft 49 is inserted through the through hole 36 of the holding fitting 31 and the holding hole 42 of the connecting plate 44, and then the bolt hole 39 of the holding fitting 38. Screw the bolt 23 into the screw hole 43 of the connecting plate 44 to fix the horizontal arm 45 to both holding brackets 31, 38, and attach the bracket member 49 to the parent pile or shelf pile. . When a gap is created between the connecting arm 46 and the flange surface of the H-shaped steel 24, the connecting arm 46
The adjusting bolt 53 provided near the lower end of the is put in and out and brought into contact with the flange surface.

In the case of another embodiment, attachment to the H-section steel 24 is easier than in the case of one embodiment. Other functions and effects are similar to those of the first embodiment.

In the other embodiment described above, the holding fitting 38 is provided with the bolt hole 39, but the bolt 39 is provided on either of the holding fittings 31, 38 facing each other.
If a nut is screwed onto the screw 51 of the holding shaft 49 to attach to the holding metal fittings 31, 38, the bolt hole 39 may be used as the through hole 36.

Further, although the angle members 41, 41 ', 41 "are used for the holding member 40, the angle members 41, 41', 41" are provided if flat surfaces are formed on the upper surface of the horizontal arm 45 and the outer side of the connecting arm 46, respectively, and have strength. Any of groove steel, T-shape steel, etc. may be used in place of "".

Further, in the holding member 40, the connecting plate 44 having the holding hole 42 is used at the connecting portion of the horizontal arm 45 and the connecting arm 46, but the both arms 45 and 46 are directly connected without using the connecting plate 44. The reinforcing tube 14 may be used as in the example.
