[Industrial applications]

 The present invention relates to an inexpensive main landing gear installation device that can adjust the installation position of a main landing gear embedded in a foundation at a ground position and can be embedded in concrete.

Conventionally, when embedding a main leg material in a foundation, a method of adjusting the position of the main leg material, installing the main leg material at a predetermined position, and then pouring concrete has been adopted. At this time, to install the main landing gear, place the mounting base at the bottom of the foundation hole, put the main landing gear on it, adjust the position of the main landing gear with the base mounting base, and move the main landing gear to the specified position. Was often installed. Therefore, the installation work of the main leg material had to be performed at the bottom of the foundation hole, and the workability was poor and dangerous. In addition, after the main landing gear is installed, rebar is placed around the main landing gear before casting concrete, but if the installed main landing gear moves at a certain time, the installation must be corrected again. And the task was very difficult.

[0003] In addition, when the main leg is installed in a foundation hole that cannot be accessed by humans, it is necessary to adjust the installation height and installation position at the opening of the foundation hole, and it is difficult to make fine adjustments. Was.

[0004]

[Problems to be solved by the invention]

 In order to solve such problems, the present invention adjusts the installation position of the main leg material embedded in the foundation at the ground position, can be fixed at a predetermined position, and can be embedded in the foundation at low cost. It is intended to propose a material installation device.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in the device of the present invention, one end of the ring adjustment member and the frame are attached with a nut, and the other end of the ring adjustment member and the main leg holding ring are connected by a link joint via a support member. It was done.

[0006] Further, the frame and the suspension bolts are attached with nuts.

[0007]

[Action]

 By the above means, in the main leg material installation device, the ring adjusting member and the frame are attached with the nut, and the ring adjusting member moves up and down according to the tightened state of the nut. When the ring adjusting member is moved upward, the end of the support member linked to the ring adjusting member is lifted, and the end of the support member receives a reaction force from the foundation hole wall. The support member that has received the reaction transmits the reaction perpendicular to the foundation wall to the main leg holding ring.

When the support portion stands upright on the foundation wall, the main leg holding ring linked to the other end of the support portion can move in the horizontal direction. Since the main leg holding ring is fixed by being wound around the main leg, when the ring adjusting member is adjusted to move the main leg holding ring horizontally, the main leg also moves right and left in synchronization.

[0009] The four ring adjusting members of the main leg material installation device are connected to four front, rear, left and right locations of the main leg material holding ring via support members. By changing the amount of nut tightening of the ring adjustment member attached to the frame, the reaction force obtained by the support part from the foundation wall can be adjusted, and the main leg holding ring can be moved back and forth and left and right with four ring adjustment members. Adjust and fix the horizontal mounting position of the main landing gear.

[0010] The frame is provided with suspension bolts, and the main leg material is suspended with the suspension bolts, and the mounting height of the main leg materials is adjusted by adjusting the amount of tightening of the nut attached to the suspension bolt. I do.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is an overall view of the main leg material installation apparatus, in which a ring adjusting member 2 and a frame 1 are joined by a nut 3, and the ring adjusting member 2 extending vertically downward includes a main leg material holding ring 4 and a support member 5. It is a state that the link connection 6 is made via the.

As shown in FIG. 1, a main leg material installation device B is mounted on a main leg material A, and inserted into a hole C excavated for driving a foundation. To attach the main leg material installation device B to the main leg material A, the main leg material holding ring 4 is fixed to the center of the main leg material A, and a plurality of suspension bolts 7 are fixed to the upper position of the main leg material A. do it.

As shown in FIG. 2, in order to install the main leg material A in the hole C for foundation, the main leg material A with the main leg material installation device B is inserted into the hole C for foundation, Frame 1 is fixed. After fixing the frame 1, the mounting height of the main leg A is adjusted by tightening the suspension bolts 7 with the nuts 8.

As shown in FIG. 2, the horizontal position of the main leg material A is adjusted by moving four ring adjusting members 2 attached to the frame 1 up and down. The other end of the ring adjusting member 2 is link-joined 6 to a support member 5 which is link-joined 6 to the front, rear, left and right of the main leg material holding ring 4. As the ring adjusting member 2 is moved upward, the support member 5 obtains a larger reaction force than the foundation hole wall, and rises perpendicularly to the foundation hole wall. When the support member 5 rises vertically to the foundation hole wall, the main leg holding ring 4 linked to the support member 5 is pushed, so that the main leg holding ring 4 can move in the horizontal direction.

After the horizontal installation position of the main leg material A is adjusted by the ring adjustment member 2, the nut 3 is tightened to fix the ring adjustment member 2, whereby the installation position of the main leg material can be adjusted and fixed.

As shown in FIG. 3, a method of connecting using a jack 9 instead of the support member 5 via the ring adjusting member 2 and the main leg holding ring 4 is also effective. The jack 9 also expands and contracts vertically with the foundation hole wall by receiving a reaction force from the foundation hole wall. At this time, it is preferable to mount the jack 9 so that the jack 9 moves the main leg material holding ring 4 right and left by moving the ring adjusting member 2 up and down. A plurality of jacks 9 are attached so that the main leg material A can be adjusted right and left and back and forth.

As shown in FIG. 4, after the main leg material A is installed and fixed by the main leg material installation device B, concrete is poured into the hole C for the foundation and the foundation is poured. The main landing gear installation device B is embedded in the concrete poured together with the main landing gear A.

[0017]

[Effect of the invention]

 The present invention has the following effects by performing the above-described procedure.

[0018]

According to the main leg material installation device of the first aspect, the installation position of the main leg material embedded in the foundation can be adjusted by the link adjusting member and the suspension bolt attached to the ground position, so that the workability of the main leg material installation is improved. Safety is improved.

Furthermore, the main leg material installation device can be manufactured at a low cost because it can be assembled with a simple structure and with a small number of parts, and is economical even when embedded in concrete.
