Description

[Technical field]

[0001] The present invention relates to a rope fixing device for cleaning buildings, and more specifically, to an invention that can be easily assembled to the reinforcing bars that make up the walls and pillars of a building, and then installed on the exterior wall of a building by pouring concrete, and that is devised to ensure safety by tensioning a cleaning rope that hangs a worker when wiping and cleaning the exterior walls and windowpanes of a high-rise building.

[0002] In particular, the present invention relates to a rope fixing device for cleaning buildings, which can improve ease of use by reinforcing a case fixed to reinforcing bars and allowing a rope fixing tool housed inside to move smoothly in response to pressure when pouring concrete. [Background technology]

[0003] Generally, when carrying out maintenance work or facility construction on the exterior walls of a high-rise building, or when cleaning the exterior walls of windows, tiles, etc., a worker is suspended from a rope and descends from the top of the building to clean. At this time, the rope must be tied and secured to the top of the building, so that typical high-rise buildings are equipped with a rope fixing device for suspending such a rope.

[0004] In particular, a rope fixing device for cleaning buildings must be firmly attached to the wall of the building so as to be able to safely support a person suspended from the rope.

[0005] Therefore, in general, when constructing a building, a rope fixing device for cleaning a building is installed by tying and fixing a case to a steel frame or reinforcing bar that is placed inside the wall of the building, and then pouring concrete so that the case and the reinforcing bar are embedded in part of the wall, thereby forming a safe and sturdy installation structure.

[0006] That is, when pouring concrete to form the exterior wall or pillar of a building to install a rope fixing device for cleaning a building, the part to which the rope is tied is exposed to the exterior wall surface of the building, and the remaining part is tied to and embedded in the reinforcing bars of the building's wall.

[0007] An example of a prior art that satisfies the above conditions is Korean Utility Model Registration No. 20-0459687. The technology described in this publication is a rope fixing device for cleaning buildings, which comprises a main body with a groove formed on the front surface, a mounting hole formed through the rear wall surface of the main body, a fixing piece inserted into the mounting hole, a rope loop fastened to the tip of the fixing piece for hanging a rope, and a rebar insertion hole formed at the rear end of the fixing piece for inserting and fixing an auxiliary rebar to be installed inside the wall of a building, and two brackets are protruded on the rear side on both sides of the mounting hole, and the fixing piece inserted into the mounting hole is configured to be fixed and attached to the brackets.

[0008] However, the above-mentioned prior art has the inconvenience of having to secure the auxiliary rebars to the vertically formed rebars one by one by wrapping wire around them, and has problems such as the position of the main body fluctuating because it is supported only by the fixing pieces assembled with the auxiliary rebars when pouring concrete, causing the front of the main body to become blocked by concrete or the rope loops to become unable to move.

[0009] In addition, since the fixing piece of the rope fixing device is fixed only to the auxiliary rebar and supported by the wall of the building, as the building ages, the wire and concrete that assembled the auxiliary rebar may fall off, making it impossible for the rope fixing device to be stably fixed. As a result, there is a problem that the safety of workers cannot be guaranteed.

[0010] Furthermore, the main body of the rope fixing device is formed from a relatively thin metal plate, and the worker hooks the rope to the rope loop housed inside by pulling it; however, due to the injection pressure of the mortar when pouring concrete to form the exterior wall of the building, or the volume expansion pressure during the concrete curing process, the entire side of the main body becomes distorted and concave toward the inside where the rope loop is located, and as a result the rope loop cannot be pulled, making it impossible to hook the rope, or the main body can be damaged by pulling the rope loop too hard. [Prior art documents] [Patent documents]

[0012] The present invention has been devised to solve the problems of the prior art as described above, and its purpose is to provide a rope fixing device for building cleaning that allows the ring fastener to be directly connected to the reinforcing bars of the building, preventing the case from moving loosely and ensuring the safety of the worker.

[0013] Another object of the present invention is to provide a rope fixing device for cleaning buildings in which a side panel reinforcing portion is formed on the side panel of the case so that the side panel of the case does not warp despite the pressure associated with pouring concrete, thereby allowing the rope loop to move smoothly.

[0014] Furthermore, still another object of the present invention is to provide a rope fixing device for building cleaning in which a case bracket attached to the lower part of the back surface of the case can be connected to a reinforcing bar, so that the case supported by the ring fastener and the case bracket can be held in a fixed position even when concrete is being poured. [Means for solving the problem]

[0015] According to the present invention, which solves the technical problems described above, the present invention comprises a main case 10 having a ring accommodating section 12 formed inside a housing with an open front and a fastener fitting hole 13 formed at the upper part of the ring accommodating section 12, a ring fastener 30 having a rope ring 35 rotatably assembled to one side of a ring fixing plate 31 and the other side being inserted into the fastener fitting hole 13 of the main case 10 and having a building reinforcing bar 3 assembled to the reinforcing bar assembly hole 32 at the tip, and a case bracket 20 fixed to the lower part of the back surface of the main case 10 and supported by the building reinforcing bar 3.

[0016] In addition, the main body case 10 may be configured so that the side plate 18 of the ring accommodating section 12 has a shape selected from a vertical "|" shape, a horizontal "-" shape, or a "+" shape in which the horizontal and vertical directions intersect, and at least one side plate reinforcing section 19 is protruded.

[0017] Furthermore, the side plate 18 of the main body case 10 may further be provided with a side warp prevention band 50 which is bent continuously at an incline on both sides of the side support plate 53 and has a side fixing plate 51 welded to the upper and lower surfaces of the side plate 18.

[0018] Furthermore, the main body case 10 may be configured so that a fastener welding plate 14 protruding toward the rear side along the periphery of the fastener fitting hole 13 is provided and is supported by a surface of a ring fixing plate 31 inserted into the fastener fitting hole 13 and welded to the surface.

[0019] Furthermore, the main body case 10 may be configured so that the inner wall surface of the ring accommodating portion 12 and the inner wall surface of the fastener welding plate 14 formed at the upper part of the fastener fitting hole 13 are flush with each other, and the ring fixing plate 31 inserted into the fastener fitting hole 13 may be supported by a surface against the inner wall surface of the ring accommodating portion 12.

[0020] Furthermore, the ring fastener 30 may be configured such that a plurality of reinforcing bar assembly holes 32 are formed in the ring fixing plate 31 at intervals equal to the diameter of the reinforcing bars 3, so that the horizontal reinforcing bars 3 arranged on the front or rear surface of the vertical reinforcing bars are inserted through the reinforcing bar assembly holes 32 for assembly.

[0021] Furthermore, the case bracket 20 may be configured to be composed of a fixed receiving plate 21 provided on one side and welded to the bottom surface of the main case 10, and a locking receiving plate 23 extending further toward the back surface of the main case 10 with its tip bent upward, and a connecting member 40 to be assembled with the reinforcing bar 3 is fitted into a bracket fitting space 25 arranged between the main case 10 and the locking receiving plate 23.

[0023] Furthermore, the ring fastener 30 may be configured so that a reinforcing bar insertion portion 32a is formed at the bottom of the reinforcing bar assembly hole 32 of the ring fixing plate 31, and the reinforcing bar insertion portion 32a is inserted from the top of the reinforcing bar 3 to assemble it into the reinforcing bar assembly hole 32.

[0024] In addition to these, the ring fixing plate 31 may be formed so that the spacing between the reinforcing bar insertion portions 32a is smaller than the inner diameter of the reinforcing bar assembly hole 32, and a locking claw 34 may be provided at the tip of the reinforcing bar insertion portion 32a connected to the reinforcing bar assembly hole 32 so that the reinforcing bar 3 tightly fitted into the reinforcing bar assembly hole 32 is caught on the locking claw 34 and prevented from moving into the reinforcing bar insertion portion 32a. Effect of the Invention

[0025] According to the present invention, the ring fastener can be easily connected directly to the reinforcing bars of a building and firmly installed in a concrete wall, thereby preventing the case from moving loosely and ensuring the safety of workers.

[0026] In addition, by using the side panel reinforcement portion formed on the side panel of the case to prevent the side panel from warping against the pressure associated with pouring concrete, the rope ring placed in the ring housing portion can be pulled and pushed in smoothly, improving usability.

[0029] The rope fixing device for cleaning buildings of the present invention is an invention designed to be easily assembled to the reinforcing bars that make up the walls and pillars of a building, and then installed on the exterior wall of the building by pouring concrete.The invention is designed to ensure safety by tensioning the cleaning rope that hangs the worker when wiping and cleaning the exterior walls and windowpanes of a high-rise building.

[0030] In particular, the case fixed to the reinforcing bars is reinforced so that the rope fixing device housed inside can move smoothly in response to the pressure applied when pouring concrete, thereby improving ease of use.

[0031] The features of the rope fixing device 100 for cleaning buildings according to the present invention will be better understood from the embodiments described in detail below with reference to the accompanying drawings.

[0032] Since the present invention can be modified in various ways and can have various embodiments, specific embodiments are illustrated in the drawings and described in detail in the detailed description. It is not intended to limit the present invention to the specific embodiments, but it should be understood that the present invention includes all modifications, equivalents, and alternatives within the spirit and technical scope of the present invention.

[0033] First, the rope fixing device 100 for cleaning buildings of the present invention mainly comprises a main case 10 which is embedded in the exterior wall of a building, a ring fastener 30 which is passed through the ring receiving portion 12 of the main case 10 and assembled with the reinforcing bar 3, and a case bracket 20 which is fixed to the lower part of the main case 10 and supported by the reinforcing bar 3.

[0034] The main body case 10 forms a ring accommodating section 12 inside a housing with an open front, and a fastener fitting hole 13 is formed at the top of the ring accommodating section 12. A front support plate 11 is provided around the front of the ring accommodating section 12 and is bent outward to come into surface contact with the mold 2 for pouring concrete, thereby preventing concrete from flowing into the ring accommodating section 12.

[0035] In this case, it is preferable that the front support plate 11 of the main body case 10 has a plurality of screw holes 15 formed at intervals so that the mold 2 and the front support plate 11 are joined by inserting nails or fixing pins or the like into the screw holes 15 from the back surface of the front support plate 11, which is in surface contact with the mold 2, and so that the mold 2 and the front support plate 11 can be easily separated after the concrete has cured.

[0036] The main body case is a housing for forming the ring accommodating portion 12 that can be molded into one of a circular, rectangular, or daruma shape to correspond to the shapes of the ring binder 30 and the rope ring 35, but in this invention a rectangular housing will be described.

[0037] In addition, the housing of the main body case 10 is designed to be embedded in the exterior wall of a building, and the pressure of the concrete is transmitted to the top and bottom plates and side plates 18, which have a relatively thin cross-sectional thickness. Although the ring fixing plate 31 of the ring fastener 30 is supported on the top plate, causing interference, the side plates 18 are prone to distortion due to the pressure of the concrete, so a side panel reinforcement portion 19 is further formed to prevent distortion of the side panels 18.

[0038] The side panel reinforcing portion 19 formed on the side panel 18 of the main body case 10 is configured to protrude in the vertical "|" direction from the side panel 18 of the ring accommodating portion 12, and by forming at least one side panel reinforcing portion 19 on the side panel 18, the rigidity of the side panel 18 against pressure due to external forces is improved.

[0039] In addition, the side plate reinforcing portion 19 may be provided to protrude in an arc shape to improve the efficiency of processing and manufacturing, and the present invention may also include continuously arranging the shapes of circular protrusions in the vertical direction.

[0040] Furthermore, as shown in FIG. 7a, the side plate reinforcing portion 19 is formed to have a shape selected from a horizontal "-" shape or, as shown in FIG. 7b, a "+" shape in which the horizontal and vertical directions intersect, so as to improve the rigidity of the side plate 18 against pressure from an external force while also improving the manufacturing efficiency, which is also included in the present invention.

[0041] Moreover, as shown in FIG. 7c, the present invention may also include forming the side plate reinforcing portion 19 to have a shape in which a plurality of horizontal and vertical directions intersect.

[0042] And, as shown in FIGS. 2 and 3, the main body case 10 is bent and formed in the back direction along the periphery of the fastener fitting hole 13, and a fastener welding plate 14 protruding is provided, and is supported and welded to the surface of the ring fixing plate 31 of the ring fastener 30 inserted into the fastener fitting hole 13.

[0043] At this time, the main body case 10 is configured to be arranged such that the inner wall surface of the ring accommodating portion 12 and the inner wall surface of the fastener welding plate 14 formed at the upper part of the fastener fitting hole 13 are flush, and the top surface of the ring fixing plate 31 inserted into the fastener fitting hole 13 is supported on the surface of the inner wall surface of the ring accommodating portion 12, so that the main body case 10 can be supported more stably.

[0044] The ring fastener 30 has a rectangular plate shape corresponding to the shape of the fastener fitting hole 13, and a rope ring 35 is rotatably assembled on one side of the ring fixing plate 31, and the other side is configured such that the steel bar 3 of the building is assembled into the steel bar assembly hole 32 provided at the tip inserted into the fastener fitting hole 13 of the main body case 10.

[0045] The rope loop 35 of the ring fixing plate 31 is formed to have a cross-sectional diameter smaller than that of the ring assembly hole 33, and is formed so that its outer diameter is smaller than the horizontal width of the ring housing section 12, so that an operator can connect a rope by pulling the rope loop 35 while the rope loop 35 is stored in the ring housing section 12 of the main body case 10.

[0046] Here, a front cover (not shown) that covers the ring receiving portion 12 may be further provided on the front of the main body case 10, but the present invention also includes providing hook-shaped cover fasteners on both sides of the front cover so that the ring receiving portion can be covered while the cover fasteners are assembled into the grooves of the side panel reinforcement portion 19.

[0047] Alternatively, while the front cover is supported on the front receiving plate 11 of the main case 10, a removable cover fixing pin can be inserted into the screw hole 15 to shield the ring accommodating section 12, and if necessary, the front cover can be removed to enable the rope ring to be used.

[0048] The ring fastener 30 has a plurality of rebar assembly holes 32 formed in the ring fixing plate 31 at intervals equal to the diameter of the rebar 3, so that the position of the main body case 10 can be easily adjusted and the front support plate 11 can be supported by the mold 2 that forms the wall body.

[0049] That is, the reinforcing bars 3 installed within the wall of a building are arranged such that the horizontal reinforcing bars 3 are placed on the front or rear surface of the vertical reinforcing bars and tied and fixed with wire. By fixing the horizontal reinforcing bars to the front surface of the vertical reinforcing bars or by assembling the reinforcing bar assembly holes 32 into the horizontal reinforcing bars fixed to the rear surface of the vertical reinforcing bars, it is easy to adjust the distance from the mold 2 for forming the wall without deforming the horizontal reinforcing bars or using separate reinforcing bars.

[0050] A plate-shaped case bracket 20 is welded to the lower part of the rear surface of the main case 10, and one end of the case bracket 20 is supported by the reinforcing bars 3 of the building to further improve the stability of the main case 10.

[0051] The case bracket 20 is composed of a fixed receiving plate 21 provided on one side and welded to the bottom surface of the main case 10, and a locking receiving plate 23 extending further toward the back surface of the main case 10 with its tip bent upward. The locking receiving plate 23 and the horizontal reinforcing bar may be fixed by tying them together with wire, or a connecting member 40 to be assembled with the reinforcing bar 3 may be fitted into a bracket fitting space 25 arranged between the main case 10 and the locking receiving plate 23 to be assembled.

[0052] Here, the connecting member 40 has a plate shape, and as shown in Figure 8, both ends of the spacing fixing plate 41 are formed in a shape bent downward, one end is formed so that a reinforcing bar fixing rod 42 that wraps around the reinforcing bar 3 is curved, and the bracket fixing rod 43 at the other end has a fixing protrusion 44 protruding from the center corresponding to the spacing of the bracket fitting space 25.

[0053] Therefore, with the ring fastener 30 welded to the top of the main case 10 connected to the reinforcing bar 3, the connecting member 40 is simply fitted into the bracket fitting space 25 arranged between the main case 10 and the locking receiving plate 23 from the top of the reinforcing bar 3, thereby fixing the gap at the bottom of the main case 10 and stably supporting the bottom of the front receiving plate 11 which is in surface contact with the mold 2.

[0054] At this time, it is also preferable that a bellows portion is further formed in the spacing fixing plate 41 of the connecting member 40, and when the length between the bracket fitting space and the reinforcing bar is shorter than the spacing fixing plate, the spacing fixing plate is deformed to be curved upward or downward so that the connecting member can be easily inserted and supported between the bracket fitting space and the reinforcing bar.

[0055] As an embodiment of the present invention, the ring fastener 30 may be configured so that a reinforcing bar insertion portion 32a is formed at the bottom of the reinforcing bar assembly hole 32 of the ring fixing plate 31, and the reinforcing bar insertion portion 32a is inserted from the top of the reinforcing bar 3 to assemble it into the reinforcing bar assembly hole 32.

[0056] Therefore, the convenience of installation work can be improved by first tying and fixing the horizontal reinforcing bars and the vertical reinforcing bars, and then fitting the reinforcing bars into the reinforcing bar insertion portion 32a of the ring fixing plate 31.

[0057] In addition, the ring fixing plate 31 is formed so that the spacing between the reinforcing bar insertion portions 32a is smaller than the inner diameter of the reinforcing bar assembly hole 32, and a locking claw 34 is provided at the tip of the reinforcing bar insertion portion 32a connected to the reinforcing bar assembly hole 32.The reinforcing bar 3 tightly fitted into the reinforcing bar assembly hole 32 is hooked onto the locking claw 34 and fixed to the reinforcing bar assembly hole 32 while shaking due to the impact of pouring concrete, etc., thereby restricting movement of the main body case 10.

[0058] As shown in FIG. 9, a side warp prevention band 50 arranged vertically is further welded and fixed to the side panel 18 of the main case 10, making it possible to maintain the shape of the main case 10 despite the pressure of the concrete. The side warp prevention band 50 is bent continuously at an angle on both sides of the side support plate 53 and formed into a side fixing plate 51 which is welded to the upper and lower surfaces of the side panel 18.

[0059] Therefore, by welding and fixing the side warp prevention band 50 to a product in which a side panel reinforcing portion is not formed on the side panel 18 of the main body case 10, it is possible to prevent distortion of the side panel, and it is also possible to weld and fix the side warp prevention band 50 to a product in which a side panel reinforcing portion 19 is formed on the side panel 18, thereby further improving the rigidity of the side panel 18.

[0060] In addition, the side warp prevention band 50 can be further formed with a protruding support reinforcement portion on the side support plate 53 to increase its rigidity, and the present invention also includes selectively welding and fixing it to the side and bottom surfaces of the main body case 10 to increase its rigidity.

[0061] The side support plate 53 of the side warp prevention band 50 fixed to the main body case 10 is tied with wire to the vertical or horizontal reinforcing bar 3 to fix the main body case 10, so that the main body case 10 can be supported more stably than when concrete is poured.

[0062] As described above, the above-mentioned embodiment is an explanation of the most preferred embodiment of the present invention, but the present invention is not limited to the above-mentioned embodiment, and it will be apparent to those skilled in the art that a wide variety of modifications can be made without departing from the technical concept of the present invention.
