Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simple curing morning glory attached to a temporary fence or a temporary scaffolding at a construction site.
[0002]
[Prior art]
The simple curing morning glory can be installed using a temporary enclosure cloth pipe installed outside the temporary scaffolding, or can be easily installed from a building frame such as a framed scaffolding. It is used to prevent the fall of small items such as.
[0003]
As shown in FIG. 8, the conventional simple curing morning glory is composed of a body fitting 50, a body arm 51, a connecting material 52, and a strut 53. A vertical member 54 suspended from the main body metal fitting 50 is attached along the construction site T of the frame scaffold or the cloth pipe of the temporary enclosure, and is fixed by the hook bolt 55 or the clamp. The main body arm 51 is formed of a square pipe, and a base end portion thereof is fixed to the main body metal fitting 50 via a pin. The main body arm 51 can be stowed upward after completion of the operation and set in a protruding state when the operation is performed again. The ends of the connecting material 52 and the strut 53 are attached to the gravity locks 56 at both ends of the main body arm 51, and a curing sheet (not shown) is stretched thereon. When a certain span of the building site or a standard span cannot be obtained, an extendable handrail bar is used as the connecting material 52.

[Problems to be solved by the invention]
There are 1800,1500,1200,900,600 (unit mm) in the span of the construction site of the temporary scaffolding, and the span varies by several tens of millimeters depending on the inch size system, meter size system, and the system unique to the construction company, The connecting material 52 using the conventional telescopic handrail rod has a problem that the length adjustment is troublesome. There is also a problem that a large number of struts 53 must be prepared for each system in each span.
[0007]
Further, since the vertical member 54 is suspended from the main body metal fitting 50, there are problems such as bulkiness and troublesome attachment to the building site. Furthermore, in the corner portion, it is necessary to dispose two arms at a right angle on one building, but the main body bracket 50 with the vertical member 54 cannot be attached to one building, There was a problem with the processing of the department.
[0008]

It is shown. By using the connecting material 3 in FIGS. 3 and 4, it is possible to cope with spans S _{2 to} S ₆ (1800 to 600) and to make an inch size system, meter size system, and certain construction by fine adjustment of α. Can handle company-specific systems.
[0025]
Further, in FIG. 5, by appropriately selecting the gravity lock 5 to which the connecting material 3 is attached, the gap L between the pair of connecting materials 3, 3 different in the inch size system, the meter size system, and a system unique to a certain construction company is supported. be able to.
[0026]
In addition, for the streak 4, by appropriately selecting the gravity lock 5, it is possible to use the streak 4 having the same length in an inch size system, a meter size system, or a system unique to a certain construction company. In span S ₂ , the same length striation 4 can be used. Below span S ₃ you can use the same length streak 4 for inch-size systems and a system unique to a construction company, and for meter-size systems you must use a different streak 4 '. You can reduce the type of streaking.
[0027]
FIG. 6 shows an example of the main body 1, which includes a mounting plate 30, a pair of left and right side plates 31, 31, and a reinforcing plate 32. The clamp 6 is fixed to the mounting plate 30 with bolts and nuts 33. This clamp 6 is a so-called dual-purpose clamp and can be fixed to a building with two different diameters. Fixing holes 34 corresponding to the mounting holes 12 and 12 of the main body arm 2 are formed in the side plate 31. By inserting a fixing pin 35 into these mounting holes 12 and the fixing holes 34, the main body arm 2 is attached to the main body bracket. 1 can be fixed. A plurality of (three in the illustrated example) lower fixing holes 34 are arranged on an arc centered on one upper fixing hole 34, and the main body arm 2 is inclined forward and protrudes. It can be set to an installed state or a stowed state in which it is stood on the building side.
[0028]
As shown in FIGS. 6 (d) and 6 (e), the fixing pin 35 is an L-shaped pin, and a locking claw 36 for preventing separation is provided at the tip. When the locking claw 36 is inserted into the mounting hole 12 and the fixing hole 34, it automatically drops and prevents the fixing pin 35 from being detached. The locking claw 36 is fixed to the fixing pin 35 by two pins 37, 38. By enlarging the insertion hole of the pin 38, the pin 37 is rotated by a predetermined angle around the pin 37 so that the tip end portion of the locking claw 36 can be projected and retracted. The fixing pin 35 is attached to the side plate 31 via a wire 39.
[0029]
FIG. 7 shows a plane arrangement of a simple curing morning glory in the corner portion of the temporary scaffold, and the clamps 6 of the two main body arms 2 orthogonal to each other are placed at the same height position on the corner building T _1. Can't install. Therefore, as shown in FIG. 7 (b), a mounting plate 30 made of L-shaped steel (angle material) is mounted on two orthogonal surfaces of the base body 6a of the clamp 6, and a pair of L-shaped steel 30 is attached to each of two sides. by providing the two body fitting 1, 1 attached to the side plates 31 and 31, as shown in FIG. 7 (a), Kenchi T ₁ of the corner, located two body arms 2,2 orthogonal can do.
[0030]
In addition, the clamp 6 cannot be placed on the adjacent building sites T ₂ and T ₃ at the connecting portion of the two temporary scaffolds that are orthogonal to each other at the corner portion. Therefore, the clamp 6 is fixed to one building site T _2. It is necessary to fix the main body arm 2 of the clamp 6 and the unsupported main body arm 2 ′ without the clamp. However, the main body arm 2 and the main body arm 2 ′ can be doubled by making the main body arm a circular steel pipe. It is possible to connect with a clamp.
