Description

Safety net structure for building construction

The present invention relates to a safety net structure that is installed for the safety of workers and to prevent falling objects during construction work, and more particularly, the installation work of the pipe structure by adopting a ladder-type prefabricated pipe structure, a support method using a bracket, and the like. It is possible to carry out the installation work on the inside of the building or safety net, so that the worker can be safely protected from the danger of falling, etc. In particular, the length and angle of exiting to the outside of the building are sufficient because the length can be extended using the assembly characteristics of the pipe structure. By securely securing, it is possible to greatly increase the functionality of the safety net structure, and also relates to a safety net structure for construction engineers using a structural characteristic exhibited by the ladder form to secure a balanced sense of stability for the structure.

In general, in the case of various construction sites, safety nets are installed to prevent tools, various building materials, and workers from falling to the ground during inadvertent or other various reasons.

The safety net can guarantee the safety of the worker, and also can ensure the safety of workers and pedestrians on the ground, so it is a very important means that must be installed at the construction site.

In general, the installation and dismantling of safety nets requires the worker to go outside the building and move through a scaffolding pipe or safety net structure to connect or dismantle the pipe structure and the safety net. Therefore, the worker must always work with the risk of being exposed to safety accidents. There is.

Although safety ropes are used to prevent falling accidents during work, most workers do not wear safety ropes because of the inconvenience that the safety ropes cause interference or obstacles when the workers move and work. Due to this, there is a problem that frequently occurs safety accidents of workers.

On the other hand, most of the pipe structure applied to the existing safety net structure uses a pipe of a fixed length (4m long pipe), in this case, due to the characteristics of the pipe structure is usually installed inclined about 45 ° narrow area extending out of the building as a safety net There is a drawback of not being able to fulfill the function, and when it is installed almost horizontally without giving an angle to compensate for this, there is a disadvantage that the structural stability is lowered and the safety net is not easy to clean.

To this end, the applicant has filed and registered Utility Model Registration No. 389366 (Building Safety Net) on July 1, 2005. However, the length of the pipe is adjusted because the pipe structure is triangular. It is inconvenient and lacks structural stability. In addition, since the means for holding the structure is made of only wire, there is anxiety about many dangers, such as severe shaking of the safety net when high winds blow.

On the other hand, the current art provides a means for extending the length of the pipe as in the present invention, which is good workability because it is a way to weld using a connection pin 31, such as Figure 5 Also, if the connecting pin is bent after use, there is a problem such as unfolding it again or replacing it.

Therefore, the present invention has been devised in view of such a point, and adopts a method of prefabricating connecting the pipe structure and the bracket for its support so that the installation and dismantling of the safety net structure or safety net can be performed inside the building. By doing so, it is possible to protect the safety of the operator to the maximum, such as the risk of falling, and the purpose of providing a safety net structure for building construction workers can also quickly and easily install the safety net.

In addition, another object of the present invention is to ensure a sufficient length and angle of the pipe going out of the building by connecting the pipe structure prefabricated, it is possible to secure a larger safety area than the existing safety net, the installation of the safety net The state can be inclined toward the building to facilitate the handling and management of safety net cleaning, etc. In particular, by adopting a pipe structure having a ladder shape, it provides a safety net structure for construction engineers who can secure structural stability for the structure. have.

In addition, another object of the present invention is to further improve the structural stability by connecting and supporting the pipe structure and the upper wire connecting bracket with a connection pipe of 3m.

The present invention for achieving the above object is installed on each of the three consecutive layers up and down wire connection bracket for supporting the pipe structure and the pipe connection bracket between, and the upper end is connected to the wire extending from the up and down wire connection bracket And a lower end portion is connected to the pipe connecting bracket through a clamp and supported by a clamp, and the safety net structure of the construction engineer is constructed of a pipe structure on which the safety net is covered. Composed of a combination structure of two parts of the ladder possible, it is possible to connect and cover the safety net on the pipe structure side while pulling the pipe structure toward the building by using the bending structure of the clamp side of the pipe connection bracket. Of structure The ladder member is characterized by consisting of a long ladder member and a short ladder member.

In addition, the length of each long ladder and short ladder member of the pipe structure is characterized in that the total length of the pipe structure is 5m consisting of 4m and 1m. At this time, the lengths of the long ladder members 10a and the short ladder members 10b may be 3 m and 2 m, respectively.

In addition, the pipe structure is characterized in that the connection pipe and the other end of the 3m one end is bound by the clamp to the upper wire connection bracket is connected and supported.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are exploded / combined perspective view showing the components of the safety net structure according to the present invention.

1 and 2, the safety net 15, which functions to prevent the fall of workers and falling of building materials, etc. during the construction of the building for the construction of the building is installed in a structure supported by the safety net structure.

The safety net structure provided by the present invention is a pipe structure 10 to secure the open area of the safety net 15, and a plurality of brackets for supporting the pipe structure 10 and connecting the wire 15, that is, wire connection It consists of the brackets 11a and 11b and the pipe connection brackets 12a and 12b.

The pipe structure 10 is a structure that substantially holds the safety net 15 when the worker or building materials, etc. fall, consists of a combination of two parts taking the form of a ladder, each ladder member is two side by side It consists of a structure that is arranged across the short pipes between the long pipes and then connected by a conventional clamp.

For example, the ladder-shaped member of the two parts constituting the pipe structure 10 may be a combination of the long-legged member 10a and the short-legged member 10b, and the clamp 14 is connected to these connecting portions. ) Is interposed.

The long-legged member 10a and the short-legged member 10b provide an effect of significantly extending the overall length of the pipe structure 10, that is, the total length of the exiting the building, resulting in the safety net 15 It is possible to secure a sufficient area.

For example, a pipe structure made of a combination of long / short ladder members can extend the length out of the building, compared to most safety net structures that are usually made of 4m long pipes. It is possible to secure a sufficient area of 15).

In the case of the ladder-type structure consisting of the long-legged member 10a and the short-legged member 10b, the overall stability of the structure is ensured by the structural characteristics exhibited by the ladder shape.

In actual building construction, the length of each long-legged member 10a and the short-legged member 10b of the pipe structure 10 may be 4m and 1m, and the total length of the pipe member may be made 5m. . This is because the length of the pipe to be mass-produced is usually 4 m, and the lengths of the long-legged member 10a and the short-legged member 10b may be 3 m and 2 m, respectively.

Clamp 14 used in the connection between the ladder member or the bracket side of the pipe structure 10 is composed of a pair of circular holders 17 connected by the hinge portion 16 as shown in Figure 3, Commonly used ones can be used.

The pair of circular holders 17 may be coupled to the pipe side in such a way that they are opened by closing or releasing the two semi-circular members, and may be freely rotated in one direction by the intermediate hinge portion 16.

Of course, the hinge can be rotated in a state in which the fastening state is released due to the nature of the hinge part of the bolt fastening structure, and finally, after the connection of the clamp is completed, the hinge part can be fixed while being fastened again.

Therefore, by using the clamp 14, two pipes can be connected in a straight line (substantially shifted by the center distance between the circular holders), and the direction between the two circular holders 17 through the hinge portion 16 can be adjusted. When twisted, two pipes intersecting 90 ° can be easily connected.

The clamp 14 may be equally applied to each ladder member connection portion, bracket side connection portion, and wire connection portion of the pipe structure 10.

The role of supporting the pipe structure 10 or connecting the wire 13 to the concrete structure 20 side of the building is to connect the wire connecting bracket (11a), (11b) and the pipe connecting bracket (12a), (12b) is in charge.

The wire connecting brackets 11a and 11b and the pipe connecting brackets 12a and 12b are bracket bodies 18b, screw type vices 18a serving as fastening elements, and bracket bars for connecting pipes and wires. It consists of 18c.

The bracket body (18b) is made of a "c" shape is installed in a structure that is inserted into the concrete structure 20 of the jaw structure and then can be firmly fixed by tightening the screw type vise (18a), the bracket bar 18c extends a certain length from the bracket body 18b to the outside of the building, whereby the ladder 14 and the wire 13 can be connected through the clamp 14.

Meanwhile, the pipe structure 10 may have a structure in which one end of the pipe structure 10 is connected to the other end of the 3m connecting pipe 30, which is connected to the upper wire connecting bracket 11a by a clamp, as shown in FIG. 4. This eliminates the need to bind up and down like wires, since it is supported by rigid connection pipes compared to conventional loose wires. have. That is, in the case of high-rise, it is possible to further improve the safety of the safety net against strong wind.

Hereinafter, the installation process of the safety net structure according to the present invention.

First, each bracket is installed on three floors of the building. For example, a wire connecting bracket 11a for connecting a 3m long wire 13 or a 3m long connecting pipe 30 is usually provided on the top layer, and a 10m long wire 13 is usually provided on the bottom layer. ) To install the wire connecting bracket (11b) for connecting, and between the two layers to install the pipe connecting brackets (12a, 12b) at intervals between each other in order to connect the pipe structure (10). .

In this case, the 3m long wire 13 or 3m long connecting pipe 30 is used to extend the pipe structure 10 finally installed to the safety net outside the building, and the 10m long wire 13 is completely at a predetermined angle. A wire that supports the unfolded pipe structure 10.

In the state of connecting the pipe structure 10 to the pipe connection brackets 12a and 12b, two lower ends of the prefabricated pipe structure 10 are connected to the pipe brackets 12a by the respective clamps 14. To the bracket bar 18c of (12b).

At this time, the pipe structure 10 is connected to the lower end of the pipe structure 10, and the upper end of the pipe structure 10, two wires (or connecting pipes), that is, 3m long and 10m long wire is connected.

The fixing of the wire may be adopted by using a clamp 14 or the like, and the pipe structure, which is a heavy object in the pipe structure connecting operation or the wire connecting operation, may be supported by a conventional crane or the like.

The process of connecting the bar end of the safety net 15 to the pipe structure 10 may be performed inside the building because the pipe structure 10 is erected to the building.

Connecting the safety net to the pipe can be done in the usual way, and the inner end of the safety net is usually fixed to the building side.

Therefore, as in the past, the worker can completely eliminate risk factors such as going out of the building, and work can be performed quickly in a safe state because the work is performed inside the building.

When the installation installation of the safety net 15 is completed, the pipe structure 10 is flipped out by using a 3m wire to the outside of the building.

In this case, the pipe structure 10 can be easily flipped by using the hinge portion 16 of the clamp 14 mounted on the pipe connecting brackets 12a and 12b.

Subsequently, when the safety net 15 is fully unfolded, the wire 13 and the safety net 13 are firmly fixed in this state to complete the safety net.

In the case of the pipe structure thus installed, a combination of 4m and 1m (or 3m and 2m) ladder members with a total length of 5m is built at an approximately 45 ° angle, so the safety nets covered there are sufficient area (outside the building) Distance from about 3.5m), and in the case of safety net, it is about 15∼ inclined low toward the building with a height difference between the outer end connected to the upper end of the pipe structure and the inner end connected to the building side. By maintaining an angle of 20 °, it is possible to easily clean and manage the foreign matters falling on the safety net.

As described above, the safety net structure provided in the present invention can install and dismantle the safety net structure or the safety net from inside the building, and further extend the length of the pipe structure to ensure sufficient length and angle of the pipes going out of the building. As a result, the safety of the worker can be protected as much as possible from the fall, and the safety net can be installed quickly and easily, and the safety net can be secured to the outside of the building. There is an effect that can facilitate the handling and management of the back.

In addition, by employing a ladder-shaped pipe structure has the effect of ensuring a structural stability for the whole structure.

In addition, by replacing the existing loose wire with a rigid pipe has the effect of improving the safety of the safety net against strong winds.
