Description

architectural structures

[0001] The present invention relates to a construction structure, and more particularly, to a construction structure that can prevent falling of construction equipment such as a ladder, thereby improving the safety of workers.

[0002] In modern society, construction equipment such as ladders are widely used in construction sites and other workplaces.

[0003] When working at heights using these ladders, the worker climbs to the top of the ladder, causing the center of gravity to be located at the top of the ladder. As a result, the ladder loses its balance and can easily fall over, leading to safety accidents.

[0004] In order to prevent safety accidents caused by ladders falling, it is stipulated that 2 to 4 people should hold the ladder during high-altitude work. However, due to work efficiency and manpower shortages, safety accidents frequently occur due to avoidance of the above regulations.

[0005] Techniques have been proposed to improve the tipping problem of these ladders. Prior art utility model registration No. 20-0412244 proposes a system of auxiliary legs that are attached to the leg members of a standard ladder and have wider lower sections than the main ladder, thereby alleviating the problem of tipping forward, backward, and side-to-side. However, the spread of the auxiliary legs alone cannot resolve the problem caused by the weight located at the top.

[0006] Another prior art, Registered Utility Model No. 20-0479669, configured a foldable outrigger leg (tip-prevention device) on both sides of each leg of a pair of leg members so that the leg members could be supported on the ground over a wide area. However, the length of the outrigger leg (tip-prevention device) was fixed, making it difficult to use in various work environments and inconvenient to operate.

[0007] Therefore, there is a need to develop architectural structures that can be easily used in various work environments and are easy to operate.

[0008] The problem to be solved by the present invention is to provide a construction structure that is easy to operate and can increase the safety of workers by preventing the falling of construction equipment.

[0009] Embodiments of the present invention have the advantage of preventing the falling of the construction equipment, thereby increasing the safety of workers, and facilitating operation, by providing an auxiliary support member that is connected to the construction equipment and a support shaft and has an adjustable length.

In addition, one outer wall of the first protruding member (132b) for the second hook comes into contact with the end of the cover (112) for the sliding bar, so that the relative movement of the first protruding member (131b) for the first hook with respect to the sliding bar body (111) can be restricted.

[0066] The second protruding member (132c) for the second hook is formed by protruding from the inner wall of the through hole (P) for the bar and is positioned so as to face the first protruding member (132b) for the second hook. This second protruding member (132c) for the second hook passes through the second cut groove (H2) and comes into contact with the outer wall of the fixed bar portion (120).

[0067] The second guide protrusion member (132d) is formed to protrude from the second hook member body (132a) in a direction toward the first hook member body (131a) of the first hook member (131). This first guide protrusion member (131d) is arranged spaced apart from the first elastic body (133). In addition, the second guide protrusion member (132d) is arranged opposite to the first guide protrusion member (131d).

[0068] The second protruding member (132e) for the first elastic body is formed by protruding from the second hooking member body (132a) in a direction toward the first hooking member body (131a). This second protruding member (132e) for the first elastic body is arranged spaced apart from the second guide protruding member (132d).

[0069] The first elastic body (133) is arranged between the first hooking piece (131) and the second hooking piece (132). The first elastic body (133) is connected to the first hooking piece body (131a) of the first hooking piece (131) and the second hooking piece body (132a) of the second hooking piece (132) to elastically press the first hooking piece (131) and the second hooking piece (132) to move in a direction where they are spaced apart from each other. In the present embodiment, the first elastic body (133) may be formed of a ring-shaped spring into which a first protruding member (131e) for the first elastic body and a second protruding member (132e) for the first elastic body can be inserted into a central region.

[0070] Due to the elasticity of the first elastic body (133), the first catch piece (131) and the second catch piece (132) are spread apart from each other, and the lengths of the first cut groove (H1) and the second cut groove (H2) shielded by the sliding bar cover (112) formed in a shape in which one end is slanted are different, and accordingly, as illustrated in FIG. 9, the first catch piece (131) and the second catch piece (132) are inclined in a wedge shape.

[0071] In this way, the first hooking piece (131) and the second hooking piece (132) are tilted into a wedge shape by the elasticity of the first elastic body (133) and the different lengths of the first cut groove (H1) and the second cut groove (H2) shielded by the sliding bar cover (112), so that the first protruding member (131b) for the first hooking piece and the second protruding member (131c) for the first hooking piece bite the fixed bar portion (120) and the first hooking piece (131) is fixed to the fixed bar portion (120), and the first protruding member (132b) for the second hooking piece and the second protruding member (132c) for the second hooking piece bite the fixed bar portion (120) and the second hooking piece (132) is fixed to the fixed bar portion (120). In this state, one outer wall of the first protruding member (131b) for the first hooking piece comes into contact with the inner wall of the first cut groove (H1), so that the relative movement of the first protruding member (131b) for the first hooking piece with respect to the sliding bar body (111) is restricted, and one outer wall of the first protruding member (132b) for the second hooking piece comes into contact with the end of the cover (112) for the sliding bar, so that the relative movement of the first protruding member (132b) for the second hooking piece with respect to the sliding bar body (111) is restricted. Therefore, in the state of FIG. 9, the relative movement of the sliding bar part (110) with respect to the fixed bar part (120) is restricted.

[0072] In order to allow relative movement of the sliding bar (110) with respect to the fixed bar (120), as shown in Fig. 10, the worker applies an external force to the first catch piece (131) and the second catch piece (132) so that the first catch piece (131) and the second catch piece (132) are in a parallel state.

[0073] In the state illustrated in FIG. 10, at least one of the first protruding member (131b) for the first hook and the second protruding member (131c) for the first hook does not contact the outer wall of the fixed bar (120), and at least one of the first protruding member (132b) for the second hook and the second protruding member (132c) for the second hook does not contact the outer wall of the fixed bar (120), thereby allowing relative movement of the sliding bar (110) with respect to the fixed bar (120).

[0074] Meanwhile, the second elastic body (134) is positioned between the first hooking piece (131) and the second hooking piece (132) and is spaced apart from the first elastic body (133).

In the present embodiment, the second elastic body (134) may be formed of a ring-shaped spring into which a first guide protrusion member (131d) and a second guide protrusion member (132d) can be inserted into a central region.

[0075] In this way, the first guide protrusion member (131d) and the second guide protrusion member (132d) are inserted into the central region of the second elastic body (134), so that the second elastic body (134) does not come off between the first catch piece (131) and the second catch piece (132) during the stretching process of the second elastic body (134).

[0076] Meanwhile, the supporting part (140) is rotatably connected to the sliding bar body (111). This supporting part (140) comes into contact with the ground and firmly fixes the sliding bar body (111) to the ground.

[0082] The first auxiliary bracket (210) is connected to the main frame (M) of the construction equipment (20).

[0083] The first connecting bar (230) is rotatably connected to the first auxiliary bracket (210). In the present embodiment, the first connecting bar (230) is formed in a square bar shape with a hollow interior. A second connecting hole (231) is formed in the first connecting bar (230).

[0084] The second connecting bar (240) is connected to the first connecting bar (230) so as to be relatively movable and can be inserted into the interior of the first connecting bar (230). A plurality of first connecting holes (241) are formed in the second connecting bar (240). These plurality of first connecting holes (241) are formed to be spaced apart from each other and can be connected to the second connecting hole (231) by the relative movement of the first connecting bar (230) and the second connecting bar (240).

[0085] The second auxiliary bracket (220) is coupled to the sliding bar body (111) of the support shaft (100). A second connecting bar (240) is rotatably coupled to the second auxiliary bracket (220).

[0086] The bar joint (250) is connected to the first connecting bar (230) and the second connecting bar (240) to restrict relative movement of the first connecting bar (230) and the second connecting bar (240).

[0087] The bar coupling part (250) according to the present embodiment includes, as illustrated in FIGS. 2 to 4, a fixing pin (251) inserted into a first coupling hole (241) and a second coupling hole (231), a fixing body (252) coupled to the first connecting bar (230), an elastic body (253) for pins coupled to the fixing pin (251) and the fixing body (252) to elastically press the fixing pin (251), and a pin handle (254) coupled to the fixing pin (251).

[0088] The worker can pull the pin handle (254) to pull the fixed pin (251) out of the first coupling hole (241) and the second coupling hole (231). After that, when the pin handle (254) that was pulled is released after adjusting the positions of the first connecting bar (230) and the second connecting bar (240), the fixed pin (251) moves forward due to the elastic force of the pin elastic body (253), and accordingly, the fixed pin (251) passes through the first coupling hole (241) and the second coupling hole (231) to be fixed in position.

[0089] The operation of the architectural structure according to the present embodiment is described below with reference to FIGS. 1 to 11.

[0090] First, the length adjustment of the auxiliary support (200) is described.

[0091] The worker pulls the pin handle (254) to pull the fixed pin (251) out of the first connecting hole (241) and the second connecting hole (231). Then, after adjusting the positions of the first connecting bar (230) and the second connecting bar (240), when the pulled pin handle (254) is released, the fixed pin (251) advances due to the elastic force of the pin elastic body (253), and accordingly, the fixed pin (251) passes through the first connecting hole (241) and the second connecting hole (231), and the positions of the first connecting bar (230) and the second connecting bar (240) are fixed.

[0092] Next, the length adjustment of the support shaft (100) is described.

[0093] In order to adjust the position of the sliding bar (110) relative to the fixed bar (120), the worker applies an external force to the first catch piece (131) and the second catch piece (132) so that the first catch piece (131) and the second catch piece (132) become parallel as shown in FIG. 10.

[0094] In the state illustrated in FIG. 10, at least one of the first protruding member (131b) for the first hook and the second protruding member (131c) for the first hook does not contact the outer wall of the fixed bar (120), and at least one of the first protruding member (132b) for the second hook and the second protruding member (132c) for the second hook does not contact the outer wall of the fixed bar (120), thereby allowing relative movement of the sliding bar (110) with respect to the fixed bar (120).

[0095] After the position adjustment, when the worker removes the external force, the first catch piece (131) and the second catch piece (132) are tilted into a wedge shape as shown in Fig. 9 due to the elasticity of the first elastic body (133) and the second elastic body (134) and the different lengths of the first cut groove (H1) and the second cut groove (H2) shielded by the sliding bar cover (112), so that the first protruding member (131b) for the first catch piece and the second protruding member (131c) for the first catch piece bite the fixed bar portion (120) and the first catch piece (131) is fixed to the fixed bar portion (120), and the first protruding member (132b) for the second catch piece and the second protruding member (132c) for the second catch piece bite the fixed bar portion (120) and the second catch piece (132) is fixed to the fixed bar portion (120). It is fixed to the fixed bar (120). In this state, one outer wall of the first protruding member (131b) for the first hooking piece comes into contact with the inner wall of the first cut groove (H1), so that the relative movement of the first protruding member (131b) for the first hooking piece with respect to the sliding bar (110) is restricted, and one outer wall of the first protruding member (132b) for the second hooking piece comes into contact with the end of the cover (112) for the sliding bar, so that the relative movement of the first protruding member (132b) for the second hooking piece with respect to the sliding bar (110) is restricted. Therefore, in the state of FIG. 9, the relative movement of the sliding bar (110) with respect to the fixed bar (120) is restricted.

[0096] Next, the worker places the supporting member (140) in contact with the ground so that the safety tipping prevention belt (10) stably supports the construction equipment (20).

[0097] In this way, the construction structure according to the present embodiment has an auxiliary support (200) that is connected to the construction equipment (20) and the support shaft (100) and has an adjustable length, thereby preventing the construction equipment (20) from falling, thereby increasing safety for workers and providing the advantage of easy operation.

[0098] FIG. 12 is a drawing showing a non-use mode state of an architectural structure according to a second embodiment of the present invention, and FIG. 13 is a drawing showing a use mode state of the architectural structure of FIG. 12.

[0099] Hereinafter, a second embodiment of the present invention will be described. This embodiment differs from the first embodiment in that it additionally includes a climbing prevention shielding member (300). However, in other aspects, it is identical to the first embodiment of FIGS. 1 to 11. Therefore, the configuration with the difference will be described below.

[0100] The safety fall prevention belt (10) according to the present embodiment includes a climbing prevention shielding member (300) that is connected to an auxiliary support member (200) and is positioned between climbing frames (N) in a non-use mode.

[0101] The climbing prevention shielding member (300) is formed in a 'U' shape. This climbing prevention shielding member (300) is connected to the first connecting bar (230).

[0102] The climbing-prevention shielding member (300) according to the present embodiment is positioned between the climbing frames (N) in the non-use mode as illustrated in FIG. 12 to prevent the worker from climbing the construction equipment (20). On the other hand, in the use mode illustrated in FIG. 13, the climbing-prevention shielding member (300) avoids the climbing frames (N) so that the worker can easily climb the construction equipment (20).

[0103] In this way, the building structure according to the present embodiment is provided with a climbing-prevention shielding member (300) positioned between the climbing frames (N) in the non-use mode, so that the worker cannot step on the climbing frame (N) in the non-use mode when the support shaft (100) is not extended in the safety mode, and thus the worker can be prevented from climbing in the non-use mode, thereby increasing the safety of the worker.

[0104] Although the present embodiment has been described in detail with reference to the above drawings, the scope of the present embodiment is not limited to the above drawings and description.

[0105] As such, the present invention is not limited to the described embodiments, and it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications and variations should fall within the scope of the claims of the present invention.

[0106] The present invention can be used to prevent falling of construction equipment such as ladders.
