And a slide strut locked at a desired height by a joint lock member. A coupling fitting having a holder with a receiving hole is attached to the main strut or the slide strut, and the wedges are attached to both ends of the connecting material. The connecting material is coupled to the support column by fitting it into the receiving hole.

  The support apparatus according to claim 2 is the support apparatus according to claim 1, wherein a locking member inserted into the receiving hole is provided on the metal fitting body that couples the braces, and the metal fitting body is slidable. A clamping member that inserts and clamps the holder is attached to the metal fitting body.

The support apparatus according to claim 3 is the support apparatus according to claim 1 or 2, wherein the joint lock member includes a clamp member including a spring fitted to an outer periphery of the main support, and the main support. And a lock pin inserted into a lock hole formed in the slide column.

  According to the present invention, the height of the column can be easily adjusted by the slide column that is slidably inserted into the main column, and the height of the coupling bracket can be changed. It is possible to connect the connecting material and the brace with only one type of metal fitting.

It is a front view of the support apparatus of this invention. It is a side view of FIG. It is a side view of a joint lock member. It is CC sectional view taken on the line of FIG. It is an expansion perspective view of A part of FIG. It is an expansion perspective view of the B section of FIG. It is an enlarged side view of B part of FIG.

Hereinafter, embodiments of the support device of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a support apparatus, and FIG. 2 is a right side view of FIG.
The support device is composed of a support column 1 facing in the vertical direction, a connecting material 2 facing in the horizontal direction, and a brace 3 facing in an oblique direction. The support column 1 is composed of a main support column 1a provided at a lower portion and a slide support column 1b having a smaller diameter than the main support column 1a and slidably inserted into the main support column 1a. The main support 1a and the slide support 1b are connected by a joint lock member 4.

  3 and 4 show the configuration of the joint lock member 4. The joint lock member 4 includes a clamp member 5 made of a substantially semicircular spring, and a lock pin 6 fixed to the inner center of the clamp member 5 and protruding from the opening. A lock hole 7a is formed at the upper end of the main column 1a, and a lock hole 7b is formed at a predetermined interval in the slide column 1b. The lock holes 7a and 7b of the main column 1a and the slide column 1b are aligned with each other. The lock pin 6 is inserted into the lock holes 7a and 7b, and the outer periphery of the main column 1a is clamped by the clamp member 5. Thus, the slide column 1b is fixed at a predetermined height position.

FIG. 5 is an enlarged view of a portion A in FIG.
In FIG. 5, in the fitting 8, planar arc-shaped holders 11 and 11 ′ having vertical receiving holes 10 are fixed to four locations on the outer periphery of the sleeve 9. The holders 11 and 11 facing each other across the sleeve 9 have the same height, and the holders 11 ′ and 11 ′ adjacent to the holders 11 and 11 ′ are different in height. Thereby, the joining materials 2 to be joined and the brace 3 are prevented from interfering with each other. In the sleeve 9, the main support 1a is fixed to the slide support 1b by welding or the like.

  A wedge member 12 is fixed to the end of the connecting material 2. By inserting the wedge member 12 into the receiving hole 10 of the coupling bracket 8 from above, the connecting member 2 is coupled to the slide column 1b and the main column 1a via the coupling bracket 8.

FIG. 6 is an enlarged view of a portion B in FIG.
In FIG. 6, the brace fitting 14 is joined to the fitting 8. The brace fitting 14 includes a main body portion 15, a locking member 16, and a clamping member 17.

The main body 15 is formed with side plates 19 that are parallel to both sides of the rear plate 18. The locking member 16 has a notch groove 20 formed in the rear portion, and is fixed to the inner surface of one side plate 19. The sandwiching member 17 is a plate having a tapered surface 17a at the rear part.

When the brace 3 is attached to the rear part of the side plate 19 via the shaft 22, the locking member 16 is inserted into the receiving hole 10 of the holder 11 ′, and the clamping member 17 is inserted into the front part of the side plate 19, the taper surface 17 a becomes the side plate 19. The holding member 17 is pushed forward by being guided by the guide plate 21 provided inside the holder 11, and the holder 11 ′ is held by the locking member 16 and the holding member 17. When the brace fitting 14 moves upward and tries to detach from the holder 11 ′, the notch groove 20 is locked to the holder 11 ′, so that the detachment is prevented.

  As shown in FIG. 1, a screw-type jack 25 is provided at the lower end portion of the main support 1a so that the height of the support 1 can be adjusted by a rotating operation.

  By selecting the lock hole 7b of the slide column 1b and jointing to the main column 1a with the joint lock member 4, the height of the column 1 can be easily extended and the height of the coupling member 8 can be changed. It can be adapted to the size of the brace 3. Therefore, the braces 3 of various sizes can be coupled with one type of coupling member 8. In addition, the height accuracy of the support | pillar 1 can be arbitrarily set by making the space | interval of the lock hole 7 small.

The support device of the present invention is used at construction sites, and damages to the structure of the building due to earthquakes and other disasters cause secondary disasters such as collapse and collapse due to the effects of aftershocks and its own weight. In order to prevent secondary collapse when there is a danger, the damaged exterior wall, ceiling, or opening of windows, doors, etc. are supported by supporting columns to stabilize the damaged part of the building. It is also used as a structure called a shoring device.
