Abstract

The present invention provides a safety platform for scaffolds, which eliminates spaces between adjacent work platforms and thus can obviate accidents where a worker's foot slips into such spaces or a dropped tool causes damage to a worker working below the platforms. By coupling a fixing means to both ends of each work platform configured to fix the safety platform to a horizontal support bar of a scaffold system, the present invention eliminates spaces between adjacent work platforms by means of the fixing means, and thus can obviate accidents where a worker's foot slips into such spaces or a dropped tool causes damage to a worker working below the platforms. In addition, the present invention enables convenient installation and can also secure the coupling to the horizontal support bar, by forming on a lower portion of the fixing means a fixing member configured for fixing the horizontal support bar, wherein the fixing means, when hooked from above the horizontal support bar, pivots to move upward and then contacts a lateral surface of the horizontal support bar upon return, thereby fixing the horizontal support bar. In addition, by integrally forming a reinforcement bar formed below the work platforms, through integrally extrusion molding same, the present invention enables a simpler manufacturing process compared to integrally forming same by welding, and thus can reduce manufacturing costs.

Description

scaffolding safety scaffolding

The present invention relates to a safety scaffold for scaffolding, and more specifically, to an accident in which a worker's foot falls and is injured by removing the space between the working scaffold and the working scaffold, as well as an accident in which the working tool falls down and the worker working under the scaffold is injured. It relates to a safety scaffold for scaffolding that can be prevented in advance.

Looking at high-place work platforms (scaffolds, patriarchs, etc.) that are generally and commonly applied in various industrial fields such as shipbuilding, construction, and civil engineering sites, as shown in FIG. etc.), the scaffold support 10 is firmly installed at regular intervals, and a guard rail 30 is installed at the end of the scaffold support 10 to prevent safety accidents such as falling of the operator, On the scaffold support 10, one or more scaffolds 20 are installed in a state connected to each other.

However, in the conventional case, both footrests adjacent to each other have their ends overlapped up and down, and then the footrest is installed together with the support 10 by wire (W).

Looking at this in more detail, after binding the footrest located at the lower part of the footrests 20 that are connected to each other with wire to the support, put another foothold on the bound footrest, and then wire the footrest overlapped with the supporter again. It is a form of work that binds.

In the conventional high working platform as described above, in the connection structure of the scaffolding, a step is generated as much as the thickness of the scaffold because the scaffolding is connected to each other in an overlapping state. There is always a risk of a safety accident in which a worker may fall down and fall down depending on the system.

In addition, in the conventional scaffolding connection structure, since both adjacent scaffolds are connected in an overlapping state, the scaffold length is shortened by the overlapping length, thereby causing lengthwise damage to the scaffolding, and thus a greater number of supports 10, scaffolds ( 20), the installation of the guard rail 30, etc. was required, and since the footrests are bound with wires in a state of overlapping each other, unreasonable and uneconomical vulnerabilities arise such as the problem of wasting unnecessary materials and the problem of increasing the installation cost of the high-place workbench. became

Recently, as shown in FIG. 2a, a safety scaffold 100 having hook-shaped hooks 120 formed at both ends of the working scaffold 110 is being used, and such a safety scaffold 100 is as shown in FIG. 2b. Similarly, the hook 120 is hung on the horizontal support 210 and used.

However, in the scaffolding system, the safety scaffold 100 is horizontally formed so that the operator can move safely, but the working scaffold 110 and the working scaffold 110 by the hook 120 hung on the horizontal support 210. There was a problem in that a space was created in between, and the worker's foot fell into this space and injured, as well as an accident in which the work tool fell down and the worker working under the scaffold was injured.

On the other hand, due to the above problems, the present inventor has previously applied for a technology for configuring a connecting member between the scaffold and the scaffold, and the Korean Utility Model Application No. 20-2019-0004338 No. 20-2019-0004338 scaffolding connecting member for scaffolding (October 28, 2019) The scaffolding connecting member 10 of one application) has an open lower part as shown in FIG. 3, and a fixture that is inserted into and fixed to the horizontal support 110 through the open lower part; It is coupled to the upper portion of the fixture, characterized in that it comprises a connecting plate installed between the footrest 120 and the footrest (120).

However, the connection structure of the scaffolding requires a separate connection member to eliminate the space between the scaffolding, and since it takes time according to the material cost and installation of the connection member, there is a problem in that the efficiency of the operation is lowered.

Accordingly, the present inventors have developed a safety footrest that does not require a separate connecting member when connecting the footrest and the footrest, and prevents a space from occurring in the fixing means for connecting the footrest.

Therefore, the present invention has been proposed to improve such conventional problems, including an accident in which a worker's foot falls out and is injured by eliminating the space between the work scaffold and the work scaffold, and an accident in which the worker working under the scaffold is injured by the falling down of the work tool. It is a task to be solved to provide a new type of scaffolding safety scaffold that can be prevented in advance.

In particular, by combining the fixing means for fixing the working scaffold to the horizontal support bar of the scaffolding system at both ends of the working scaffold, the space between the working scaffold and the working scaffold can be eliminated by the fixing means, including accidents in which the worker’s foot falls and is injured. It is a task to solve the problem to provide a new type of scaffolding safety scaffolding that can prevent in advance the accident where the work tool falls down and the worker working under the scaffolding is injured.

In addition, by forming a fixing member for fixing the horizontal support in the lower part of the fixing means, when the fixing means is hung through the upper side of the horizontal support, the fixing member rotates and moves upward and then returns to contact the side surface of the horizontal support to fix the horizontal support It is a task to solve the problem of providing a new type of scaffolding safety scaffold that can be easily installed and fixed with a horizontal support stably.

In addition, a new type of safety for scaffolding that allows the manufacturing process to be simplified and the cost associated with manufacturing can be reduced by integrally extruding and integrally forming the reinforcing bar formed on the lower side of the working scaffold, compared to forming integrally by welding. Providing a foothold is a challenge to be solved.
