Description

[Detailed Description of the Invention] [Objective of the Invention] Industrial Field of Use The present invention is directed to a construction site where equipment can be easily moved horizontally within a scaffold consisting of multiple frames on the upper, lower, left and right sides of a construction site. This invention relates to a horizontal movement 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. However, the scaffolding was narrow and lacked stability, so the weight limit was, for example, 25 kg, making it difficult to move heavy objects horizontally.
It was even dangerous.

Problems to be Solved by the Invention The present invention aims to provide a horizontal movement device for equipment at a construction site that easily and safely moves equipment horizontally within a scaffold at a construction site.

[Structure of the invention]

Means for Solving the Problems In view of the above, the present invention provides a structure in which a horizontal rod is fixed to a continuous frame above the hierarchy of a scaffold consisting of a large number of upper, lower, left, and right frames, and a scaffold is installed below the horizontal rod. A horizontal movement device for equipment at a construction site, in which a rail is installed horizontally in the longitudinal direction through a fixture in the same direction as the scaffold board, and a guide cart is supported on the rail through rollers, and a pulley is attached to the guide cart. The present invention is intended to solve the above-mentioned drawbacks.

Function The present invention makes it easy and safe to place, hang, support, etc. equipment on a guide cart running on rails installed above each floor within a scaffold at a construction site using appropriate means. It moves in the horizontal direction.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.
2a... is a scaffold constructed by Scaffold 1
consists of a plurality of floors 3, 3a..., scaffolding boards 4, 4a... are installed below each floor 3, 3a..., and horizontal rods 5, 5a are installed above each floor 3, 3a... of the scaffold 1. ...is fixedly installed.

The horizontal rods 5, 5a, . . . may be formed by utilizing the arm tubes of the frames 2, 2a, the reinforcing tubes below the arm tubes, or may be fixedly installed as separate bodies.

6, 6a... are horizontal in the longitudinal direction of the scaffold 1 via fixing devices 7, 7a... below the horizontal rods 5, 5a... of the frames 2, 2a... which are continuous above each floor 3, 3a... of the scaffold 1. The rails are installed in the same direction as the scaffolding boards 4, 4a..., and the rails 6, 6a... have U-shaped channel steel rail members 9, 9a... having bent portions 8, 8a... at the tips. The rail members 9, 9a... have a length L of 1800 mm in the longitudinal direction.
, and one end is provided with recesses 10, 10a...
The other side has convex portions 11, 11a... corresponding to the concave portions 10, 10a..., and the concave portions 10, 10a...
The depth W of 10a... and the height H of the convex portions 11, 11a... are at least 29 mm or more, so that it can be used for both metric and inch scaffolds.

Note that 12, 12a, 13, 13a... are reinforcing members for the rails 6, 6a... and the rail members 9, 9a...

Next, to specifically explain the structure of the fixtures 7, 7a... for attaching the rails 6, 6a... to the horizontal rods 5, 5a..., the fixtures 14, 14a... form an inverted U-shape, and the upper large diameter is connected to the lower end. It is a hanging fitting in which long holes 15, 15a... are bored, and the hanging fittings 14, 14a...
The horizontal rods 5, 5a, which are fixedly installed, are fitted externally so as to be crowned from above, while each rail 6,
At each connection part of the rails 6, 6a..., the upper part of the rails 6, 6a... is further covered and fitted with a long holding board 16 having a horizontal U-shape on one side from above. The short holding plates 17, 17a, each having a horizontal U-shape on the sides, are crowned and fitted onto the outside, and bolts 18, 18a are applied from above the holding plates 17, 17a to the rails 6, 6a..., the holding board 16, and the holding plate. 17, 17a, and in the center of the holding board 16 there is a mounting bracket 20 having pins 19, 19a, etc. fixedly installed on the upper part thereof, which are inserted into the long holes 15, 15a, etc. of the hanging brackets 14, 14a, etc. , 20a are erected and fixed, and rails 6, 6a... are attached to horizontal rods 5, 5a... which are fixed to the scaffold 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 brought into contact with the lower part of the rails 6, 6a... by nuts 29, 29a. 3
0a is rotatably attached, so that the guide cart 22 can run freely on rails 6, 6a, . . . .

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

In addition, a hanging shelf 32, a net (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, etc. 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
A handle 37 is attached to one end, and a roll 35 is attached to one end.
A net 39 with a hook 38 attached to the tip is wound around the net.

In addition, when the pulley 33 is fixedly installed as shown in FIG. 1, the other end of the net 39 may be connected to the drive section 40.

Next, to explain the operation of the horizontal movement device for equipment at a construction site according to the present invention, workers move on the scaffolding boards 4, 4a, etc., and the equipment M mainly uses winches, lifts, etc. from the outside of the scaffolding 1. Transport the equipment M to floors 3, 3a, etc., then place it on the hanging shelf 32, or hook it to the hook 38 and turn the handle 37 to wind the net 39 to raise the equipment M from the scaffolding. push or pull directly to
Alternatively, the equipment M is moved horizontally within the scaffold 1 by pulling a rope (not shown) tied to the guide cart 22.

〔Effect of the invention〕

In short, the present invention provides a large number of upper, lower, left and right 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... and the guide cart 22 is supported on the rails 6, 6a... via the rollers 30, 30a, the worker can move on the scaffolding boards 4, 4a... The equipment M can be moved horizontally within the unstable scaffold 1 easily, safely and quickly, and the weight limit (approximately 25 kg) can be greatly increased (approximately 200 to 400 kg) by hand. be.

Also, since the pulley 33 was attached to the guide cart 22,
When placing it on the hanging shelf 32 or the hook 38
Its practical effects are enormous, such as being able to easily raise it from above the scaffolding boards 4, 4a, especially in the case of heavy objects.
