Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a falling object curing device installed on a frame scaffold.

[0002]

2. Description of the Related Art In the construction and repair of buildings and the like, frame scaffolds are temporarily installed outside the frame of a building. When the frame scaffolds are installed adjacent to or along a road, In order to prevent construction materials, repair materials, tools, and other articles from falling onto the road, a fallen object curing device is installed on the road in an inverted eaves shape.

The falling object curing device is composed of, for example, a pair of left and right main members facing each other and a plurality of panel members mounted between the main members, and a device main body rotatably pivotally mounted on a frame scaffold. , And a support member that connects the apparatus body to a frame scaffold.

As the supporting member, for example, Japanese Patent Publication No. 4-7
There are two configurations, a structure in which the device main body is suspended and supported from the upper side as shown in Japanese Patent No. 2023, and a structure in which the device main body is supported from the lower side as shown in Japanese Patent Publication No. 4-57888.

Particularly, in the latter construction, the support member is constructed so as to be extendable and contractible so that, in the extended state, the main material is held in a standby state in which it is held in a substantially vertical position.
The contracted state is held at a regular installation position, and the falling object curing device having such a configuration is relatively easy to install as compared with the configuration in which it is suspended from the above side. It has the advantage that there is no risk of it colliding with a supporting member and jumping out on the road, and it is expected to become more popular in the future.

[0006] Further, the apparatus body of the falling object curing apparatus is provided with a brace-like steady rest member for preventing deformation if necessary, and some panel members may be arranged in the interval direction of the main material. The one in which a plurality of sheets are arranged in the flow direction of the apparatus main body, that is, the longitudinal direction of the main material is often used. In this case, a groove portion whose opposite surfaces are open is formed in each of the main materials, and each panel member is formed. Is assembled by inserting it into the groove portion in order from the front end of the main material and sliding it toward the base end side of the main material so that the last inserted panel member is fixed to both main materials.

[0007]

However, in the above-mentioned conventional falling object curing apparatus, in order to maintain the expanding and contracting support member in a predetermined state (extended state or contracted state), the diameter of the two pipes at the overlapping position is increased. The length of the support member must be fixed with a pin or the like that penetrates in the direction, and since the work of inserting the fixing pin is carried out by leaning forward from the frame scaffold, the worker is forced to perform dangerous work. .

Further, there is a drawback that the structure of the above-mentioned supporting member is complicated, and that the supporting member has a slightly large diameter in order to give a required supporting strength, and thus becomes heavy, which makes it difficult to handle.

Further, in the falling object curing device, when the panel members inserted into the leading end portions of both main members are slid toward the base end side, the panels are inclined with respect to the sliding direction and their corners are caught by the main member to smoothly move the base member. In some cases, it may not be possible to assemble to the end. In such a case, the inclination of the panel member should be corrected, but in order to correct the inclination of the caught panel member,
It is necessary to raise the lower side of the panel member or lower the higher side of the panel member, but if you try to move the panel member in this direction, the panel will be caught more strongly, so it is easy. The above inclination cannot be corrected.

Further, in addition to the work of mounting the panel member as described above, the work of mounting the steady rest is performed outside the frame scaffolding, so that the safety of the worker is ensured only by the lifeline. It has been pointed out as a major problem in these days due to the shortage of skilled aerial workers.

In view of the above circumstances, the present invention can be simply
In addition, it is an object of the present invention to provide a falling object curing device that can be smoothly installed and has improved safety during installation work.
