Description

The present invention relates to a construction loading platform suitable for detachably attaching to the outer surface of a steel frame structure during construction of a high-rise building, receiving building materials and other loads from the outside, and carrying them into a building. is there.

At the construction site, in order to carry the load suspended by an external crane to two or more high floors, it is installed so that a shelf-like loading frame is extended outside the building. However, when such a cargo handling gantry is installed, there is a problem that the cargo handling gantry on the upper floor gets in the way when loading the cargo into the lower floor. Therefore, various loading platforms have been developed to enable loading on lower floors.

For example, in Japanese Patent Laid-Open No. 7-48023, a pair of left and right holder beams are fixed to the floor of a building, and slide beams with handrails are slidably provided on the left and right holder beams. There is disclosed an apparatus in which a carriage is installed between the two so that a slide beam and a carriage can be drawn into the housing. However, since this loading platform has only a slide beam and a carriage protruding outside, it can be easily retracted indoors and can be retracted from the outside in a short time, while a holder beam placed on the floor surface. The support beam is interposed between both ends of the upper floor and the lower surface of the slab on the upper floor, and the holder beam is pressed and fixed with a total of four support columns on the front, rear, left and right, and the holder beam is exposed on the floor. However, there was a problem that it interfered with the transportation of cargo and work indoors.

Japanese Patent Application Laid-Open No. 10-25896 discloses a vertical fixed frame fixed to the scaffold or the frame side, a horizontal base plate connected to the lower end of the fixed frame, an upper end and a base plate of the fixed frame. It consists of left and right chains and blow-up prevention materials (sticking rods) that connect the tip of the top and electric chain blocks installed on the left and right of the upper end of the fixed frame, and disengages the blow-up prevention materials and the base plate. In addition, a load handling gantry that can be folded by pulling up the tip of the base plate with an electric chain block is disclosed. However, while this load-carrying stand does not cause any obstacles to indoor work after folding, it is necessary to disengage the tip of the base plate from the blow-up prevention material when folding, and the folding work is troublesome. In addition, it takes a long time to evacuate the loading platform from the outside, and the folded loading platform remains outside the scaffolding or the frame, causing problems when loading on the lower floor. was there.

A rectangular horizontal platform that has a horizontally long main body and a front edge thereof. And a handrail erected on the left and right side edges, and a locking tool for connecting the loading hook of the chain block to the front part of the left and right side edges of the horizontal base. Left and right support bars with vertical columnar bodies fixed to the left and right in an intersecting manner, an arm projecting toward the housing side fixed to the upward part of this columnar body, and the tip of this arm protruding from the upper surface of the floor slab of the housing A bar-shaped stopper that is in contact with the horizontal steel frame for supporting the lower surface of the floor slab protrudes from the downward portion of the columnar body, and is connected to one end of a pair of left and right turnbuckles at the tip of the horizontal base. And connect the other end of the wire to the housing. Characterized by being detachably connected to the upper floor portion.

In the above construction loading platform, the left and right supports are fixed to the upper surface of the floor slab of the frame in advance by any means such as bolting or embedding, and then the loading platform body is lifted with a crane and the The tip of the arm protruding backward is connected to the support metal with a horizontal pin, one end of a wire with a turnbuckle is connected to the tip of the horizontal base, and the other end is connected to the upper floor side portion of the housing, for example, the upper floor side It is detachably connected to a flange of a horizontal steel frame that supports the floor slab, and the tip of the rod-shaped stopper is brought into contact with the horizontal steel frame for support on the bottom surface of the floor slab while lowering the loading gantry body, and the turnbuckle is attached. The wire is fixed to the housing by adjusting the length of the wire. Therefore, the downward load applied to the load handling gantry main body is supported by the horizontal pin at the upper part of the columnar body, the bar-shaped stopper at the lower part of the columnar body, and the left and right turnbuckle wires. In addition, the horizontal stopper can be easily leveled by forming the rod-shaped stopper so that the length can be adjusted.

If it is necessary to collect the cargo on the lower floor after installing the above-mentioned loading platform, separate the two chain blocks on the left and right, and use the upper floor of the chassis in the same way as the wire with the turnbuckle. Connect to the side part and hang it, hang the load hook on the hook that protrudes in front of the side edge of the horizontal base, and then pull up the front end of the horizontal base by operating the chain block. As a result, the cargo handling platform can be lifted substantially vertically and retracted into the housing. Since the left and right columnar bodies protrude almost horizontally slightly above the floor slab on the outer surface of the horizontal platform raised at this time, there is no hindrance to the lower floor loading operation. On the other hand, since only the support metal and the above-mentioned columnar body exist on the left and right ends of the floor slab in the housing, there is no problem in the housing work.

Then, when the loading work on the lower floor is completed, the horizontal platform is lowered by operating the chain block to lower the horizontal platform and bringing the tip of the stopper into contact with the horizontal steel frame below the floor slab. It is returned to the horizontal position, and work on the loading platform is possible. In addition, when the loading operation by the loading platform is completed, the chain block and the wire with the turnbuckle are removed from the upper floor side portion of the frame, and the horizontal pin connecting the tip of the arm and the support metal is removed. Allows the loading platform to be separated from the enclosure and can be lifted by a crane.

The building loading gantry according to the present invention is attached to the housing as needed using the upper and lower steel frames of the floor slab if the support metal is fixed to the upper surface of the floor slab of the housing in advance by any means. Can be easily attached to and detached from the housing. Then, suspend the chain block on the upper floor of the frame, hang the load hook on the hook at the front edge of the side of the horizontal base, and pull up the front end of the horizontal base with this chain block. The gantry can be retracted into the housing, and in this case, the left and right columnar bodies only protrude almost horizontally on the outer surface of the horizontal platform, so there is no hindrance to the loading work on the lower floor, and the housing Since there are only support metal and columnar bodies on the left and right ends of the floor slab, there is no hindrance to the work inside the housing. Then, by operating the chain block to lower the horizontal table, the horizontal table can be returned to the horizontal position, and the returning operation is easy.
