Description

[Detailed explanation of the invention] [Purpose of the invention] Industrial application field This invention is a method for horizontal movement of equipment that can easily move equipment horizontally within a scaffold consisting of multiple frames on the upper, lower, left and right sides of a construction site. The present invention relates to a combination structure of a rail and a guide cart used in a construction site for use with a device.

Conventional technology Traditionally, scaffolding at a construction site is constructed first;
It is used from the construction of the building itself to the exterior and interior, and various methods have been used to transport equipment to upper floors, but when moving horizontally, workers must carry it on scaffolding boards on each floor. Even if it is,
The scaffolding was narrow and lacked stability, so in reality, it was difficult to move heavy objects horizontally, with a maximum weight of around 25 kg, creating an extremely dangerous situation that could cause equipment to fall or cause personal injury.

Problems to be Solved by the Invention The present invention provides a combination structure of a rail and a guide cart at a construction site, which can be used as a horizontal movement device for equipment that easily and safely moves the equipment horizontally within the scaffolding at the construction site. That is.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention has been developed by fixing a horizontal rod to a continuous frame above the hierarchy of a scaffold consisting of a large number of upper, lower, left and right frames, and below the horizontal rod to a scaffold. A rail is installed horizontally in the longitudinal direction via a fixture in the same direction as the scaffolding board, the outside of the rail is opened, and a U-shaped guide cart is installed from below the rail, and a shaft is installed above the guide cart. The above-mentioned drawbacks are solved by providing a combination structure of a rail and a guide cart for construction sites, which extends horizontally into the rail and is fitted with a roller that is rotatably attached to the shaft so as to come into contact with the lower part of the rail. That is.

Function The present invention uses appropriate means to place, engage, support, etc. equipment on a guide trolley that runs on rails installed above each floor within the scaffolding of a construction site, so that the equipment can be easily and safely leveled. It moves in the same direction.

The short holding plates 17, 17a each having a horizontal U-shape on one side are used to cover and fit the rails 6, 6a, . The plates 17, 17a are tightened together, and at the center of the holding board 16 there is a mounting bracket having pins 19, 19a fixedly attached to the upper part thereof to be inserted into the elongated holes 15, 15a, etc. of the hanging brackets 14, 14a. 20, 20a are erected and fixed, and rails 6, 6a... are attached to horizontal rods 5, 5a... fixed to the scaffolding 1.
are mounted horizontally via fixtures 7, 7a, . . .

Incidentally, 21, 21a are holes for bolts 18, 18a drilled in the upper part of the rail members 9, 9a, etc., and the holes 21, 21a are elongated holes in the longitudinal direction (center The distance L' is 29 mm or more), and the recesses 10, 10 of the rail members 9, 9a...
Similarly to the formation of the convex portions 11, 11a, etc., it is possible to accommodate scaffolds of two different sizes.

22 is a U-shaped guide trolley;
Shafts 23, 23a... are fitted above the guide cart 22, and the shafts 23, 23a...
5, 25a..., flat plates 26, 26a... are fixed to the guide cart 22, while shafts 23, 23a...
The other end of... extends into the rails 6, 6a..., and the shafts 23, 23a... have bearings 27, 27a, collars 28, 28a, and rollers 30 which are brought into contact with the lower part of the rails 6, 6a... by nuts 29, 29a. 30
A is rotatably attached to the guide carriage 22 so that it can freely run on the rails 6, 6a, . . .

Note that 31 is a reinforcing plate of the guide cart 22.

In addition, a hanging shelf 32, a rope (not shown), or a pulley 33 is fixed to the lower end of the guide cart 22, which is supported by the rails 6, 6a, so as to be able to run horizontally. A rotating shaft 36 to which a roll 35 is fixed is rotatably supported, and the rotating shaft 36

[Effect of idea]

In short, the present invention consists of a large number of frames 2, 2
Horizontal rods 5, 5a... are fixed to frames 2, 2a... which are continuous above the floors 3, 3a... of the scaffolding 1 consisting of a..., and are placed below the horizontal rods 5, 5a... in the longitudinal direction of the scaffold 1. The fixture 7 is horizontal and in the same direction as the scaffolding boards 4, 4a...
Since the rails 6, 6a... are attached via the rails 7a..., the worker can move on the scaffolding boards 4, 4a... and easily, safely and quickly move the equipment M horizontally within the narrow and unstable scaffold 1. The manual weight limit (approximately 25 kg) has been significantly increased (approximately 200 to 400 kg).
Also, the outside of the rails 6, 6a... can be opened, and the U-shaped guide cart 18 can be inserted into the rails 6, 6a...
The shafts 23, 23a are installed horizontally on the rails 6, 6 above the guide cart 22.
a... is extended and fitted into the shaft 23, 23a.
Since the rollers 30, 30a are rotatably attached to the rails 6, 6a so as to be in contact with the inner lower part thereof, the rollers 30, 30 rotate on the rails 6, 6a, and the guide cart 22 can easily move horizontally. Its practical effects are enormous, such as being able to move the equipment M horizontally within the scaffold 1 by placing it on a hanging shelf connected to the guide cart 22 or hooking it to a hook.
