Description

The present invention relates to a handrail used to safely assemble the scaffold by reordering upwards when assembling multi-stage frame scaffolds and other similar scaffolds installed at a construction / civil engineering site, In particular, the present invention relates to a leading handrail that can be used for a master rope connecting lifelines.

In general, at a construction / civil engineering site, as shown in Patent Documents 1 and 2, a passage and a scaffolding board are installed corresponding to the work position, and a pair of struts facing each side of the passage and a space between the struts. A master rope is erected and the end of the lifeline is joined to this master rope, or it is slidably attached to ensure the safety of the operator. In other words, by connecting a lifeline wrapped around the worker's body to the master rope, even if the worker walks down the passage of the scaffolding or falls off the scaffolding while working, the lifeline The operator is prevented from falling to the ground.

On the other hand, frame scaffolds are often installed at construction and civil engineering sites, and when assembling the framework scaffolds vertically and horizontally, for example, as shown in Patent Document 3, the leading handrail is placed on the lower scaffold plate in advance. The building frame and scaffolding plate are assembled further upward while using this leading handrail for safety. That is, when the frame scaffolding is sequentially assembled upward, the leading handrail is always replaced in advance.

Usually, a master rope is provided on both sides of the passage, and handrails are often not provided on both sides of the passage. For this reason, if a handrail is not installed, there is a danger that an operator will step out of the passage at a high place and fall below the passage during work. At this time, since the worker is supported by the lifeline, it is prevented to some extent from falling to the ground or colliding with an obstacle below the passage.

However, since the master rope disclosed in Patent Documents 1 and 2 is a rope, when the operator falls, the rope bends or stretches. The worker falls downward by a distance corresponding to the amount of bending or stretching, and the load on the worker increases according to the drop height. When this load increases, the tightening force on the worker's body increases with the lifeline, which is dangerous and development of countermeasures is demanded.

On the other hand, in the frame scaffolding where the leading handrail is arranged, the safety of the worker is achieved by using this leading handrail, but there is still a risk that the worker who has stepped off the scaffolding board will fall down from the gap of the handrail. There is a desire for improvement.

Accordingly, an object of the present invention is to provide a leading handrail that also serves as a master rope so that a large load is not applied to the worker even if the worker falls from the work path or the scaffolding plate.

In order to achieve the above-mentioned object, one preceding handrail of the present invention has a frame scaffold B comprising a pair of left and right building frames A, A and a scaffolding plate 13 installed between the building frames A, A from below to above.

The support column 2A is detachably coupled to the third mounting member 23 in the adjacent building frame A so as to be continuously arranged in the lateral direction, and the horizontal support column 4A is used as a support for the master rope. The guide 10 is slidably inserted into the horizontal support 4A.
Similarly, the other means is that when the frame scaffold B comprising the pair of left and right building frames A and A and the scaffolding plate 13 laid between the building frames A and A is sequentially assembled from the bottom to the top, In the leading handrail installed on the building frames A and A while being replaced, a pair of left and right short vertical struts 2C, a long vertical strut 3C, and a plurality of shafts 12A and 3C that are rotatably supported via pins 12A. First and second mounting members 7 and 8 which are provided on the upper side of the horizontal columns 4C and 4C, and are attached to the building frame A so as to be detachably attached to the lower side of one long vertical column 3C; A pipe 3a coupled to the first and second mounting members 7, 8; a guide 10 slidably inserted into the lateral strut 4; and a lifeline 9 coupled to the guide 10; A hollow guide body 10a inserted into the guide body and a lifeline handle suspended from the guide body 10a It is composed of a metal fitting 10c and a split portion 10b having a width larger than the outer diameter of the pin 12A formed on the side of the guide body 10a, and a long vertical column 3C is inserted into the pipe 3a to be detachably coupled to the building frame A. Then, the end portions of the horizontal struts 4C, 4C are protruded laterally from the short vertical struts 2C, and are detachably inserted into the end portions of the horizontal struts 4C, 4C in the adjacent preceding handrail, and continuously in the lateral direction. The guide 10 is inserted into the horizontal strut 4 while being arranged and using the horizontal strut 4 as a strut for the master rope.

Similarly, the other preceding handrails are sequentially assembled when a frame scaffold B comprising a pair of left and right building frames A and A and a scaffolding plate 13 installed between the building frames A and A is sequentially assembled from below to above. Kenwaku a while changing Sheng upwards in the prior handrail installed in a, and a long vertical strut 103 and the left-right pair of short vertical posts 102, and axially supported rotatably by a pin 112 to each vertical strut 102 and 103 horizontal A column 104 , first and second mounting members 70 and 80 which are provided at the lower part of the long vertical column 103 and detachably couple the vertical column 103 to the lower part of the building frame A; And a guide 100 inserted movably in the rotation direction, and a lifeline 9 coupled to the guide 100, a hollow guide main body 101 in which the guide 100 is inserted into the horizontal strut 104, and a side of the guide main body 101.

According to the preceding handrail according to the present invention, when the frame scaffolding or the like is sequentially assembled upward, the work is performed safely by installing the upper building frame, the scaffolding plate, or the fixed handrail every time the frame is assembled.

Moreover, because the horizontal strut is used as a strut for the master rope, and a lifeline is connected to this via a guide, even if the operator falls, the horizontal strut does not bend or stretch greatly, so the operator's fall distance Can be shortened as compared with the conventional rope, thereby reducing the load and impact on the worker and improving the safety for the worker. That is, since the horizontal strut is a rigid body, even if the operator falls from the work path or the scaffolding plate, a large load is not applied to the worker and it is safe.

Furthermore, even if the frame scaffolding is continuous in the horizontal direction, the guide moves along the horizontal support, so that the operator is always supported by the horizontal support through the lifeline at any position.
In particular, according to the first and second aspects of the invention, even if the pin that pivotally supports the horizontal strut protrudes in the horizontal direction, the split portion straddles the pin and the other preceding adjacent one from the horizontal strut on one preceding handrail side It can pass to the side rail of the handrail
Further, according to the invention of claim 3, since the guide is inserted so as to be movable in the horizontal direction and the rotational direction, even if the horizontal struts are continuously connected in the horizontal direction, they are coupled to the vertical struts. Since the split part can pass through the pin, the guide body can slide in the horizontal direction along the horizontal support.
On the other hand, when the guide main body comes to the position of the central column , the guide main body is rotated 90 degrees to change the position to the downward position of the split part. It can slide laterally without causing interference.
