Description

The present invention relates to a net member attaching device for temporary scaffolding, for example, at a construction site.

Temporary scaffolding is used for construction of structures such as houses and buildings, painting of outer walls, and construction for rain leaks. The temporary scaffolds are mainly frame scaffolds, single-pipe scaffolds, bracket one-sided scaffolds, wedge-tightened scaffolds (also called "Bike scaffold" (registered trademark)), overhanging scaffolds, hanging scaffolds, hanging shelf scaffolds, log scaffolds, etc Are listed.

Preventing accidents such as workers falling from the scaffolding, conversely, preventing collisions of passers-by and falling objects from construction sites with passers-by, family members, neighbors, etc. In order to prevent damage to the building, a curing sheet (also referred to as a "construction sheet") is usually provided between the rows of pedestals (also referred to as "struts") on the side opposite to the structure of the temporary scaffold. ) Is stretched.

This curing sheet has a structure in which it is erected so as to form a wall surface in the vertical direction because the construction work is necessarily a laminated structure. Therefore, in the event of a typhoon, a strong wind/strong wind will be received on the vertical surface. The curing sheet is mainly designed in a mesh shape such as a mesh sheet, so that it is designed to allow some ventilation, but since it has a role of preventing the scattering of paint and water, it has a considerably fine mesh. Therefore, the curing sheet cannot avoid the situation of receiving the wind, even if it passes the wind. In this case, there is no problem if it is a little wind, but the reality is that the scaffold sways when a typhoon or strong wind hits. In addition, when the curing sheet receives gusts/storms/strong winds, this creates a pressing force in the lateral direction, which causes accidents such as scaffold collapse.

To prevent such accidents, before the gusts/storms/strong winds caused by typhoons act on the vertical surface of the curing sheet, remove the sheet temporarily so as not to receive the wind, and adjust the sheet tension as soon as the influence of the wind disappears. Needs to be restored. If you take the wind, you cannot eliminate the risk of collapse, but if you leave the seat removed, you can ensure the original safety (prevention of falling of objects, prevention of falling of workers). This is because it will not be possible to achieve this, and in principle the state of tensioning the seat should be maintained. Normally, two or four workers work together to form a set of curing sheets, and the seats are separated by a span of one scaffold with different workers holding both sides of the seat, and the seat is expanded to the vertical plane. A string is passed through a ring formed at the right and left end portions of the seat in the vertical direction at a pitch of, for example, 300 mm, and the string is attached to the vertical material of the scaffold (in the case of a single pipe scaffold, a vertical single pipe, In the case of a frame scaffolding, it is tied to a frame vertical member to fix it in the lateral direction, and then a string is passed through a ring perforated at a pitch of, for example, 300 mm in the lateral direction near the upper and lower ends of the seat. It is common to perform the work of fixing it in the vertical direction by binding it to the horizontal member.

In order to remove the curing sheet temporarily installed in this way, contrary to the above, two or four workers made up a group, which was passed through the ring and tied to the vertical and horizontal members of the scaffold. You will have to untie the strings one by one, and fold the sheet while bundling the strings so that they will not be lost for convenience during recovery. Due to the above-mentioned circumstances, the sheet temporarily removed in this manner needs to be immediately restored. For restoration, the above-mentioned work of tensioning will be followed.

FIG. 1 is an example of a diagram showing a state in which a curing sheet as a mesh member is attached to a general temporary scaffold.

A building frame 3 having a fixed base metal fitting 2 is installed vertically and horizontally on a pair of floor plates 1, and a cross bracing 4 is provided between the pillars 3-1 of the building frame 3. A cloth frame 5 with a plate is arranged at a horizontal seating position 3-2 of the building frame 3 which faces the building frame 3.

The worker 200 is about to attach the curing sheet S as a mesh member to the temporary scaffold 100-1.

When the curing sheet S is normally deployed, eyelets are formed on the four sides as a plurality of through holes for passing a plurality of strings, and the strings are tied to the pedestal or the like through the eyelets. To attach the curing sheet S, a separate mounting component is required, and product management is also required. Moreover, it takes time and effort to attach the curing sheet S, and the worker may lose his balance and step out.
