Description

Firewall panel {A panel for protective wall}

The present invention relates to a panel for a firewall used to be installed in the H-beams installed at regular intervals in order to extend the road or to perform construction without interference from rocks and soil during construction or civil works.

In general, when expanding roads, crushing rocks or removing soils during construction or civil engineering work, H beams are placed at regular intervals of about 2m between the work site and the roads or flat sections, and are machined into squares in the space of the beams. By inserting wood to form a firewall of a certain height, in recent years, in terms of safety and economics, a panel for barriers made of metal materials is mainly used instead of rectangular wood.

The barriers installed in this way are installed for the purpose of preventing the damage of vehicles or various safety accidents passing through the road by preventing rock or soil from leaking out during rock crushing or soil removal.

The panel for the firewall used for the above purpose is presented the following techniques, in addition to the various presented, various technologies are still being developed.

In Korean Utility Model Registration No. 0221908, two to five protective plates connected to the connecting protrusion formed in the H-beams installed at regular intervals are projected on both sides of the body to protrude connecting slopes to form an outward bend. And, by inserting the bolt into the assembly hole of the body is proposed a rock fracture protection device configured to form a protective wall with a nut in the fixing hole of the fixing plate from the outside of the wing,

The design panel No. 0370765 is presented by the present applicant for the firewall panel used by combining the '' 'shaped panel with the same direction in FIG. 8,

As shown in FIG. 9, a panel for a firewall used by combining 'c'-shaped panels in a zigzag form is presented as a design registration No. 0302397 by the present applicant.

In the case of the firewall panel made as shown in Figure 8 has the advantage of being installed between the H-beams are installed at regular intervals do not leak soil outward, 'c' shaped when lifting by using a crane or excavator Since openings of the section steel are arranged in the same direction, the load is swept toward one side, which causes inconvenience in installation.

In the case of the barrier panel made as shown in FIG. 9, when installed between the H-beams installed at intervals when lifting using a crane or excavator, there is an advantage that the load is slightly removed to one side, and the installation is easy. As shown in Fig. 10, the soil is leaked.

In addition, as shown in FIG. 11, the fixing plate of the fixing member used to fix the H beam is often rotated by the frequent impact load generated by the rock, and thus, the fixing state is often released between the H beam and the barrier panel. .

The present invention is to solve the above disadvantages,

The barrier panel is made of 'c' shaped steel and 'ㅁ' shaped steel to prevent tipping and leakage of soil.

In addition, an object is to prevent the fixed state from being released between the H beam and the barrier panel even when the fixing plate is rotated by the impact applied to the barrier panel.

The present invention to achieve the above object,

In the panel for the protection wall which is installed in the H-beams provided at regular intervals and used to block the inflow of rock or soil, and the fixing member for fixing the panel to the H-beams,

The panel is made of 'c' shaped steels installed so as to be visible in one direction, and 'ㅁ' shaped steels stacked with the 'c' shaped steels,

The fixing member is composed of a bolt installed through the 'c' shaped steel, a fixing plate installed through the bolt and a nut fastened to the bolt, and the fixing plate is fixed even when rotated by shock and vibration. It is made of a square or circle with a through hole formed so that the bolt can be inserted in the center so as not to be released.

In addition, side plates are further installed on both sides of the 'ㅁ' shaped steel so that inflows such as earth and sand do not enter the inner side of the 'ㅁ' shaped steel.

By using the panel made by stacking the 'c' shaped steel and 'ㅁ' shaped steel as described above, it is possible to prevent the phenomenon of installation by preventing the phenomenon to be pulled to one side during installation. There is.

In addition, by using a fixed plate formed in a square or circular shape of the fixing plate for fixing the panel, even if the fixing plate is rotated by the impact and vibration applied to the panel for the barrier, the fixing state is not released between the H beam and the panel for the barrier wall. It is effective in preventing safety accidents.

Referring to the accompanying drawings in more detail with respect to the panel for the present inventors,

As shown in FIG. 1, the barrier panel A of the present invention is installed in an H beam provided at regular intervals to block rocks and soils, and to block rocks and soils and the like. It consists of the fixing member 2 which fixes (1) to H beam.

The panel 1 is manufactured by combining the 'c' shaped steel 11 and the 'ㅁ' shaped steel 12 in a suitable number of layers.

In the exemplary embodiment of the present invention, for example, the panel 1 manufactured by using the five section steels is described as an example. Usually, the panel 1 is composed of three to six section steels. Assemble or weld.

When the panel 1 is manufactured, the 'c'-shaped steels 11 have a plate 11a portion at the front and an opening 11b at the rear.

In addition, when the panel 1 is manufactured, the 'c' shaped section 11 is disposed at the top and bottom, and only the 'ㅁ' shaped section 12 is installed between the 'c' shaped section 11 or 'c' shaped section 11 and ' ㅁ '-shaped steel 12 can be installed.

The 'ㅁ' shaped steel 12 used in the production of the panel 1 may be used by cutting a long 'ㅁ' shaped steel of an integral type as shown in FIG. 7A, or cutting a long 'ㄷ' shaped steel as shown in FIG. 7B. And the plate can be welded and used to recreate 'ㅁ' shaped steels.

In addition, the side plate 13 may be welded to the side surface as shown in FIG. 3 in order to prevent foreign matters such as earth and sand from being inserted into the inner space of the 'ㅁ' shaped steel after installation of the barrier panel A. FIG.

3 and the fixing member 2 are usually disposed at four corners of the panel 1 to stably fix the panel 1, and the bolt 21 and the bolt installed through the panel 1 are installed. It consists of a fixing plate 23 that is penetrated through the 21 and the nut 22 is fastened to the bolt 21 to apply a fastening force to the fixing plate 23.

The fixing plate 23 is formed in a square or circular shape as shown in FIGS. 5 and 6 so that the fixing member 2 may be fixed to the H beam even after the shock and vibration applied to the panel for the barrier wall.

In general, the firewall panel A is subjected to shock and vibration due to rock and construction, and thus, the fastening force of the bolt 21 and the nut 22 of the fixing member 2 is weakened, or the shock and vibration are illustrated in FIG. 11. As described above, the fixing plate 23 may rotate. However, when the fixing plate 23 is formed in a square or a circle as described above, and the bolt 21 penetrates through the center portion, the fixing state of the panel 1 is canceled by the rotation of the fixing plate 23. It can be prevented.
