Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to an assembly scaffold that is locked at the building frame positions at both ends of each layer of the scaffold when the scaffold is used at each site such as construction and civil engineering. It relates to the end safety frame.

(Prior art) Conventionally, when scaffolding is used at each site of construction work, civil engineering work, etc., steel pipes (single pipes) are clamped laterally by clamps at both ends of the building frame that are arranged at appropriate intervals. It is a dead end by doing.

(Problems to be solved by the invention) However, the conventional method requires a lot of work time and materials for mounting, and the worker is often troublesome, so that it is dangerous.

The present invention has been made in view of the above points, and an object thereof is to provide an end safety frame in an assembled scaffold that can be locked at an appropriate place of a building frame and that is safe for the scaffolding user. And

(Means for Solving the Problems) The gist of the present invention for achieving the above-mentioned object is that it has a substantially U-shaped configuration composed of vertical frame portions (2) (2) ′ and horizontal frame portions (3). In the frame body (1) of the above, the hook-shaped locking portion (4) that locks to the left and right horizontal bars (7) (7) 'of the building frame (6) is attached to the end of the vertical frame (2) (2)'. ) (4) ', and the upper horizontal frame (11) is provided between the vertical frame parts (2) (2)'.
(2) (2) 'and both corners (5) (5)' formed by the horizontal frame (3)
The end safety frame in an assembly scaffold is characterized in that the horizontal frame portion (3) is formed so as to project from both sides in a U shape so that the horizontal frame portion (3) is longer than the horizontal width of the building frame (6).

(Operation) As described above, the end safety frame in the assembly scaffold of the present invention is
By locking the frame body (1) at appropriate positions on both sides of the building frame with the locking portions (4), (4) ', the frame body (1) at the opening of the building frame (6).
The horizontal frame part (3) of the scaffold is formed for a dead end extending laterally, and is used at both ends of each layer of the scaffold assembled by a building frame, a cloth plate and the like.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of the present invention, FIG. 2 is a perspective view showing another embodiment of the present invention, and FIG. 3 is a perspective view of a state of use of the present invention.

In the drawing, (1) is the frame body, and the vertical frame part (2) using round steel
(2) 'and a horizontal frame part (3) are deformed U-shapes, and the ends of the vertical frame parts (2) (2)' are folded back to provide hook-shaped locking parts (4) (4) ' . The width between the vertical frame parts (2) (2) ′ is slightly shorter than the lateral width of the building frame (6), and the horizontal bars (7) (7) ′ of the building frame (6) engage the locking parts (4) ( Four)'
The width of the vertical frame portions (2), (2) 'is set to an appropriate length so as to fit various building frames (6). Both corners (5) (5) 'of the frame body (1) are formed to project in a U-shape in both directions, and the distance between the corners (5) (5)', that is, the length of the lateral frame (3). Is longer than the total length of the upper rod (10) of the building frame (6). (11) is the upper horizontal frame,
It is a single frame whose both ends are bent at a right angle, and is integrally formed at an appropriate position between the vertical frame parts (2) and (2) 'in parallel with the horizontal frame part (3). The upper horizontal frame (11) is the horizontal bar of the target building frame (6).
(7) Depending on the location and the length of the vertical frame portion (2), it may not be provided as shown in FIG. 2, and conversely, two upper horizontal frames (11) may be provided at appropriate intervals. (6) is a torii type building frame, which is the same as the conventional building frame, such as leg rods (9) (9) ', upper rods (10), reinforcing rods (8) (8)'.
The length of the reinforcing rod is not particularly limited.
The location and number of the horizontal bar (7) interposed between (8) and the rod (9) are appropriate.

Therefore, the safety frame of the present invention is assembled into the building frames at both ends of the scaffold.
When using it for (6), take the safety frame from the scaffolding side as shown in Fig. 3, and attach it to the left and right horizontal bars (7), (7) 'of the building frame (6) respectively with the locking parts (4) ( By locking 4) ′, the frame body (1) can be easily locked to the building frame (6), and the horizontal frame (3) and the upper horizontal frame (11) can be used to open the building frame (6). A two-stage horizontal frame is formed. In addition, the frame body (1), due to the leg rod (9) of the building frame (6),
Since it never opens to the outside, it is safe even if an operator hits the frame body (1).

Further, in the present embodiment, the frame body (1) is a modified U-shape, but may be a straight or arc-shaped single frame, in which case the horizontal frame portion (3) becomes the frame body (1) itself, The frame body (1) can be detachably attached to the horizontal bar (7), the reinforcing rod (8), and the leg rod (9) at both ends, and the retained frame body (1) can hold its height. A shaped locking part (4) shall be provided. In addition, a horizontal frame that blocks the passage is formed in advance on the building frame (6) itself, and a building frame dedicated to the end
As (6), it is possible to omit the attachment and detachment of the frame body (1).

(Effects of the Invention) As described above, according to the present invention, since the locking portion is hook-shaped, it is very easy to attach / detach to / from the building frame, it is very easy to carry, and the safety frame is provided. Since there is no screw part in the machine, there is no fear of rusting, there is no need for a worker to cut out, and the safety during work is extremely high. or,
Since it has a very simple structure, it is extremely easy to process, there are few points to be repaired, even if there is any, it can be easily cured, and the cost is low.
