Description

Technology Field

[0001] The present invention relates to a plate scattering prevention device, and more specifically, to a plate scattering prevention device that provides a double wire system capable of effectively absorbing the kinetic energy of the plate and confining the falling range within a certain trajectory in an emergency situation where the bonding force of the plate is lost. Background Technology

[0003] Recently, due to the increase in high-rise buildings and the expansion of demand for renewable energy, the installation of stone panels and metal panels on building exteriors, as well as solar panels on rooftops and walls, is surging.

[0004] These plates are typically secured to the frame using rigid connection methods with bolts, anchors, or simple brackets.

[0005] However, these traditional fixing methods have the following technical limitations.

[0006] First, if continuously exposed to strong winds, earthquakes, or external vibrations, there is a high risk of bolt loosening or material fatigue failure, leading to a loss of bonding strength in the plates.

[0007] Second, if the connecting member is damaged, the plate will fall along an unexpected trajectory due to gravity and wind load, which causes serious secondary damage to pedestrians or surrounding structures.

[0008] Third, existing fall prevention nets detract from the appearance and are cumbersome to install, and in the case of wire support methods, it is difficult to resolve the wire sagging phenomenon that occurs over time.

[0009] In this regard, a technology for supporting solar panels using steel wires has been proposed in the past (Prior Art Document 1), but this focused on simply supporting multiple panels in a grid form, and had the disadvantage of lacking the ability to absorb dynamic loads and restrain the falling trajectory when individual panels are uncoupled. Prior art literature

[0011] Republic of Korea Registered Patent No. 10-1004108 Republic of Korea Registered Patent No. 10-2939894 The problem to be solved

[0012] The present invention aims to solve the problems of the prior art described above. The objective of the present invention is to provide a plate scattering prevention device that provides a double wire system capable of effectively absorbing the kinetic energy of the plate and confining the falling range within a certain trajectory in emergency situations where the bonding force of the plate is lost.

[0013] In addition, another objective of the present invention is to provide a plate scattering prevention device that can ensure the reliability of the system for a long period of time by maintaining the wire tension constant even with changes in the external environment. means of solving the problem

[0015] A technical concept for achieving the present invention is a plate scattering prevention device comprising: a frame forming a structural framework of a building or apparatus; a plate disposed on the upper side of the frame; and a scattering prevention means provided between the frame and the plate to prevent the plate from detaching from the frame and scattering upon external impact or release of connection.

[0016] In addition, the above-mentioned scattering prevention means comprises: a coupling member that integrally fixes and combines the plate to the upper side of the frame; a first wire disposed at the lower side of the frame, with both ends fixed to the frame and extending in the longitudinal direction; and a second wire, one end of which is connected to the first wire and the other end of which is connected to the back surface of the plate, which transmits the dynamic load of the plate to the first wire to restrain the detachment trajectory when the coupling force of the plate is lost due to damage to the coupling member.

[0017] In addition, the first wire is fastened with a predetermined tensile force applied to the lower part of the frame so as to absorb, through elastic deformation, the impact load transmitted through the second wire when the plate detaches.

[0018] In addition, at least one of the second wires is provided spaced apart at regular intervals along the length direction of the first wire.

[0019] In addition, a plate material scattering prevention device characterized by having a tension maintaining device installed on the first wire.

[0020] In addition, the above-mentioned scattering prevention means includes a coupling bracket that supports the plate material to surround it and is in close contact with one side of the frame.

[0021] In addition, the coupling bracket comprises an insertion portion that wraps around the plate, a first contact portion that is bent and extended from the lower side of the insertion portion and is in close contact with one side of the frame, and a second contact portion that is bent horizontally from the first contact portion and is in close contact with the lower surface of the frame.

[0022] In addition, a protrusion that is bent is further formed on the lower side of the second contact portion, and the first wire is made to pass through the protrusion. Effects of the invention

[0024] In the technical concept for achieving the present invention, the plate scattering prevention device according to the present invention can fundamentally prevent the free fall of the plate by having the second wire hold the plate and the first wire elastically absorb the impact even when the connecting member is damaged.

[0025] In particular, through a structure in which the protrusion of the coupling bracket is threaded onto the first wire, the bracket itself slides on the wire to disperse the impact and has the effect of ensuring the final structural stability of the system. Brief explanation of the drawing

[0028] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined by the description in the claims.

[0029] Meanwhile, the terms used in this specification are for describing the embodiments and are not intended to limit the invention. In this specification, the singular form includes the plural form unless specifically stated otherwise in the text. As used in this specification, "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components, steps, operations, and / or elements to the mentioned components, steps, operations, and / or elements. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0030] FIG. 1 is a schematic perspective view showing the state in which a plate material scattering prevention device according to one embodiment of the present invention is installed, FIG. 2 is an enlarged perspective view showing the tension maintaining device and lower wire connection structure shown in FIG. 1, FIG. 3 is a front cross-sectional view showing the state in which the device of the present invention is coupled to a frame and a plate material, and FIG. 4 is an enlarged cross-sectional view showing in detail the coupled state of the tension maintaining device applied to the present invention.

[0032] Referring to FIGS. 1 to 4, a plate material scattering prevention device according to one embodiment of the present invention is largely composed of a frame (100), a plate material (200), and a scattering prevention means (300).

[0033] The above frame (100) is a member that forms a structural framework such as a roof or outer wall of a building, and mainly square steel pipes (square tubes) can be used in multiple numbers.

[0034] The above plate (200) is a finishing material or exterior material placed on the upper side of the frame (100).

[0035] The above scattering prevention means (300) is a means to prevent the plate material (200) from detaching from the frame (100) and flying away due to impacts such as a gust of wind.

[0036] The above scattering prevention means (300) includes a connecting member (310), a first wire (320), and a second wire (330).

[0037] The above connecting member (310) is provided in the form of a screw, bolt, press cap, molding bar, etc., and primarily fixes the plate (200) to the upper side of the frame (100), and in the present invention, the state in which a molding bar is used is shown.

[0038] The first wire (320) is positioned at the bottom of the frame (100) and both ends are tightly fixed to the frame structure side and extend along the length direction of the frame.

[0039] The second wire (330) is provided in a vertical direction, with one end tied or connected to the first wire (320) at the bottom, and the other end fastened to the back surface of the plate (200) or to a plate fixing part.

[0040] The above second wire (330) may be provided in multiple numbers spaced apart at regular intervals along the length direction of the first wire (320).

[0041] Through this structure, even if the upper connecting member (310) is destroyed by strong winds, the plate (200) is suspended from the lower first wire (320) via the second wire (330) so that it does not scatter outwards.

[0042] In particular, the first wire (320) is fastened with an initial tension (tensile force) applied so that it can absorb the impact dynamic load transmitted through the second wire (330) when the plate (200) is detached through linear elastic deformation.

[0043] In addition, a tension maintaining device (400) is installed on the first wire (320) so that the first wire (320) can maintain stable tension.

[0044] The above tension maintaining device (400) includes a housing (410), a first wire connecting part (420) connected to one side of the housing (410), a second wire connecting part (430) connected to the other side of the housing (410), and an elastic member (440) disposed inside the housing (410) and disposed between the first wire connecting part (420) and the second wire connecting part (430). With this configuration, the phenomenon of the first wire (320) line automatically unwinding is prevented and the tension can be stably maintained.

[0046] FIG. 5 is a schematic perspective view of a plate-type shatter prevention device with a coupling bracket additionally applied according to another embodiment of the present invention, FIG. 6 is an enlarged view of a key part of FIG. 5, FIG. 7 is a front cross-sectional view of a plate-type shatter prevention device with a coupling bracket additionally applied according to another embodiment of the invention, FIG. 8 is an enlarged view of a key part of FIG. 7, FIG. 9 is a perspective view of a coupling bracket applied to another embodiment of the present invention, and FIG. 10 is a side view of a coupling bracket applied to another embodiment of the invention.

[0047] Referring to FIGS. 5 to 10, as another embodiment of the present invention, the scattering prevention means (300) may further include a coupling bracket (500) that firmly interlocks the plate (200) and the side of the frame (100).

[0048] The above-mentioned connecting bracket (500) may have a multi-stage bent shape as shown in FIGS. 9 and FIGS. 10.

[0049] Specifically, it includes an insertion part (510) that supports wrapping around the end of a plate (200), a first contact part (520) that is bent downward vertically from the lower side of the insertion part (510) and is in close contact with one side of the frame (100), and a second contact part (530) that is bent horizontally again from the first contact part (520) and is in close contact with the lower side of the frame (100).

[0050] In addition, the upper part of the insertion part (510) may be formed to be inclined downward so as to elastically support the plate.

[0051] Furthermore, a protrusion (540) that is bent vertically downward may be further formed on the lower side of the second contact portion (530).

[0052] The above-mentioned protrusion (540) has a perforated hole formed therein, which serves to guide the first wire (320) described above to pass through the protrusion (540).

[0053] Through this, the connecting bracket (500) acts as a primary structural support that prevents the plate (200) from coming off, and at the same time, it acts as a guide that firmly maintains the path of the first wire (320).

[0054] The plate scattering prevention device of the present invention configured as described above exhibits the following protective action and effects in environments where unexpected external impacts, such as strong winds or gusts, are applied.

[0055] Even if the connecting member (310), which is the primary fixing means, is damaged or the fastening force is lost due to continuous wind load, the plate (200) remains suspended from the lower first wire (320) through the second wire (330) connected to the back surface.

[0056] At this time, the first wire (320) effectively absorbs the instantaneous impact and dynamic load generated as the plate (200) detaches through linear elastic deformation.

[0057] This can fundamentally prevent the plate from completely separating and scattering into the air, thereby preventing secondary casualties and property damage.

[0058] In addition, even if large displacement behavior or continuous vibration occurs due to wind when exposed to an outdoor environment for a long period, the tension of the first wire (320) is not loosened by the tension maintaining device (400).

[0059] In addition, the additionally applied connecting bracket (500) wraps around the end of the plate (200) and is in close contact with the side and bottom surface of the frame (100) in multiple stages, thereby significantly improving the primary structural support force that resists detachment of the plate.

[0060] In addition, by consistently guiding the penetration path of the first wire (320), which extends lengthwise through the protrusion (540) at the bottom of the bracket, and preventing sagging, it serves to maximize the durability and ease of construction of the entire system.

[0062] The present invention has been described with reference to one embodiment illustrated in the attached drawings, but it will be understood by those skilled in the art that various modifications and other embodiments are possible. Explanation of the symbols
