Description

Technical Field

[0001] This application relates to the field of architectural decorative structures, and in particular to a prefabricated stair railing. Background Technology

[0002] Stair railings are an essential personal safety protection product for buildings. Their main function is to prevent people from falling from heights and ensure their safety. Secondly, stair railings also have certain guiding and decorative functions.

[0003] According to the manufacturing process, stair railings can be divided into welded stair railings and assembled stair railings. Welded stair railings mainly use welding rods of the same material as the base material to weld the various stair components into a whole; assembled stair railings mainly involve dividing the stair railing into various prefabricated components, and then transporting the prefabricated support components to the installation site for installation.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When installing stair railings, the supports and handrails need to be transported to the installation site. However, the handrails on stair railings are either welded or integrally formed. Integral handrails have relatively high requirements for installation and transportation space during transportation and installation. On-site welding installation of railings is inefficient and costly. Furthermore, when railings are damaged, the efficiency of dismantling integrally formed or welded railings is low. Utility Model Content

[0005] To address the issue of low installation and dismantling efficiency of stair railings, this application provides a prefabricated stair railing.

[0006] The prefabricated stair railing provided in this application adopts the following technical solution:

[0007] A prefabricated stair railing includes a support, a column fixed to the support, and a first handrail disposed at the end of the column away from the support. The handrail is characterized in that: clamping plates are provided on both sides of the column; glass is fixedly connected between the clamping plates of adjacent columns; a locking mechanism for locking the clamping plates is fixedly connected to the column; a movable column head is fixedly connected to the end of the column away from the support; a movable rod is hinged to the movable column head; a double-ended stud is fixedly connected to the movable rod; the double-ended stud passes through the movable rod; and threaded holes adapted to the double-ended stud are provided at both ends of the first handrail.

[0008] By adopting the above technical solution, when installing the support column, the support column is installed on the support, the glass is installed in the clamping plate, and the locking mechanism fixes the clamping plate to both sides of the support column. When installing the first handrail, the threaded hole at the end of the first handrail is aligned with the double-headed stud on the movable rod, and the first handrail is fixed to the movable rod by twisting it. Then, the other end of the handrail is fixed to the movable rod, and the movable rod at the other end of the first handrail is fixed to the movable column head. The movable rod on the movable column head is rotated according to the angle of the stairs to adjust the angle between the movable rod and the movable column head to be consistent with the inclination angle of the stairs. The entire first handrail is disassembled into a segmented structure, which makes it easier to transport and install the railing on site.

[0009] Optionally, the locking mechanism includes a control box fixed to the side of the support column away from the support, a locking rod slidably connected to the end of the control box near the support, a locking groove formed on the clamping plate away from the support, and a receiving plate fixed to the side of the support column near the support. The locking mechanism also includes a lifting assembly for controlling the lifting and lowering of the locking rod.

[0010] By adopting the above technical solution, when installing the clamping plate, one end of the clamping plate is placed against the receiving plate, the lifting component controls the locking rod to move away from the locking groove, the position of the clamping plate is adjusted so that the locking rod is aligned with the locking groove, the lifting component lowers the locking rod so that the locking rod extends into the locking groove, and the clamping plate is fixed on the support column.

[0011] Optionally, the lifting assembly includes a rotating rod rotatably connected inside the control box, a cam coaxially fixed to the rotating rod, a movable plate and a sliding plate slidably connected inside the control box, a spring disposed between the movable plate and the control box and passing through the locking rod, wherein the spring between the movable plate and the control box is more than the spring on the locking rod, and the movable plate is fixedly connected to the locking rod.

[0012] By adopting the above technical solution, twisting the rotating rod causes the cam on the rotating rod to rotate with the rotating rod. The cam presses against the moving plate, causing the moving plate to move upward. The spring on the locking rod causes the locking rod and the moving plate to move upward, aligning the locking groove on the clamping plate with the locking rod. Releasing the rotating rod causes the spring between the moving plate and the control box to move the moving plate downward. The moving plate causes the cam to rotate, and the cam presses against the moving plate, causing the moving plate to move downward. The moving plate then drives the locking rod to insert into the locking groove, fixing the clamping plate to the pillar. When the glass is damaged, twisting the rotating rod can remove the clamping plate from the side of the pillar, improving the removal efficiency when the guardrail is damaged.

[0013] Optionally, the receiving plate has a slot, and the clamping plate has a protrusion that matches the slot fixed at one end near the support.

[0014] By adopting the above technical solution, when installing the clamping plate, the protrusion on the clamping plate is aligned with the slot. The slot can initially fix the clamping plate on the support column, and make it easier to align the locking groove on the clamping plate with the locking rod, making the support column installation more convenient.

[0015] Optionally, both ends of the movable rod are fixed with connecting pipes to facilitate the installation of the first handrail.

[0016] By adopting the above technical solution, when installing the first handrail on the movable rod, the connecting pipe is opened, the first handrail is inserted into the connecting pipe, the first handrail is twisted to tighten the double-ended stud and the threaded hole, and then the connecting pipe is locked to tighten the first handrail. The connecting pipe can make the threaded hole inside the first handrail align with the double-ended stud, making the installation of the first handrail more convenient. At the same time, the connecting pipe can prevent the first handrail from loosening after prolonged use.

[0017] Optionally, a glass support plate is fixedly connected inside the clamping plate, and a fixing plate is fixedly connected to one end of the clamping plate away from the support. The glass support plate is threadedly connected to the fixing plate, and the glass is bonded to the glass support plate.

[0018] By adopting the above technical solution, when the glass is broken, the clamping plate is first removed from the support, and then the screws are turned to remove the glass support plate from the fixing plate. The damaged glass is then replaced, which prevents small glass shards from being left in the clamping plate when the glass is broken, thus reducing the difficulty of maintenance.

[0019] Optionally, a glass support circular support is fixedly connected to the end of the clamping plate near the support, and the glass support plate has a groove that matches the glass support circular support.

[0020] By adopting the above technical solution, the glass support ring can make the clamping plate and the glass support plate more secure, and avoid loosening between the glass support ring and the glass support plate.

[0021] Optionally, a second handrail is fixed to the side of the support column.

[0022] By adopting the above technical solution, the second handrail fixed to the side of the support can prevent pedestrians from directly contacting the support, keep pedestrians away from the edge of the stairs, and meet the needs of people of different heights.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When installing the first handrail of the staircase, align the movable rod with the movable column head, and fix the rotating rod with screws. Then align the end of the first handrail with the connecting pipe, and align the threaded hole at the end of the first handrail with the double-ended stud. Twist the first handrail to fix it to the movable rod. Then tighten the other end of the first handrail to the movable rod. Tighten the movable rod fixed to the other end of the handrail to the movable column head, and adjust the angle between the movable rod and the movable column head so that the first handrail is parallel to the inclined surface of the staircase. Compared with transporting the one-piece molded first handrail to the site for installation, or welding the first handrail, this first handrail has lower requirements for transportation and installation space, and the installation and dismantling operations are simple, which can effectively improve the efficiency of installation and dismantling.

[0025] 2. When installing stair glass, the glass is placed in a glass support plate, which is then installed in a clamping plate using a fixing plate. The clamping plate is then fixed to both sides of the support column using locking rods. If the glass is damaged, the clamping plate can be directly removed, and the glass support plate can be taken out and replaced, reducing the difficulty of maintenance. At the same time, when installing the glass on site, it is only necessary to fix the clamping plate to the support column using locking rods. Installation and removal are simple and efficient, effectively improving the efficiency of installation and removal. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a prefabricated stair railing. (Refer to...) Figure 1-3The prefabricated stair railing includes a support 1, on which a support column 3 is fixedly connected. A first handrail 2 is provided at the end of the support column 3 away from the support 1. The first handrail 2 is a stainless steel pipe with a diameter of 51mm and a wall thickness of 2.5mm. Clamping plates 71 are provided on both sides of the support column 3. Glass 72, which is transparent tempered glass with adhesive, is fixedly connected between the clamping plates 71 of adjacent support columns 3. Locking mechanisms for locking the clamping plates 71 are provided on both sides of the support column 3 away from the support 1. A detachable... The movable column head 41 is rotatably connected to the movable column head 41, and the movable column head 41 and the movable rod 42 are fixed together by anti-theft screws. The movable rod 42 is fixedly connected with a double-ended stud 43. Both ends of the first handrail 2 are provided with threaded holes that are compatible with the double-ended stud 43. Both ends of the movable rod 42 are welded with connecting pipes 44, which are steel pipes compatible with the first handrail 2. The double-ended stud 43 can also be a steel pipe with threads on the inner wall, and the two ends of the first handrail 2 are also provided with threads that are compatible with it.

[0033] During installation, the support column 3 is welded or threaded onto the support 1, the glass 72 is installed between the two clamping plates 71, and the clamping plates 71 are fixed to the support column 3 by the locking mechanism. The movable rod 42 and the movable column head 41 are fixed by turning the anti-theft screw. The first handrail 2 is inserted into the connecting pipe 44, so that the threaded hole on the first handrail 2 is aligned with the double-ended stud 43. The first handrail 2 is turned to fix the first handrail 2 to the movable rod 42. Then the other end of the first handrail 2 is tightened to fix it to the movable rod 42. Then the movable rod 42 is fixed to the movable column head 41. Each section of the first handrail 2 is installed in this way. The connecting pipe 44 can prevent the first handrail 2 from loosening and falling off after long-term use. When fixing the movable rod 42 to the movable column head 41, the angle of the movable rod 42 is adjusted so that the first handrail 2 is parallel to the inclined surface of the stairs, which effectively reduces the installation time of the railing and improves the installation efficiency.

[0034] Reference Figure 1-3The locking mechanism includes a control box 51 welded or threaded to the side of the support column 3 away from the support 1, a locking rod 52 slidably connected to the bottom of the control box 51 in a vertical direction, a locking groove 53 opened on the end of the clamping plate 71 away from the support 1, and a receiving plate 54 fixedly connected to the side of the support column 3 near the support 1. The direction of the locking groove 53 is parallel to the direction of the first handrail 2. The receiving plate 54 has a slot. The clamping plate 71 is integrally formed with a protrusion that matches the slot. The depth of the slot is small. A rotating rod 61 is rotatably connected inside the control box 51. A cam 62 is coaxially fixed to the rotating rod 61. A moving plate 63 and a movable plate 64 are slidably connected inside the control box 51. The moving plate 63 is fixedly connected to the end of the locking rod 52 near the first handrail 2. A spring passes through the locking rod 52. Two springs are also provided between the movable plate 64 and the control box 51. One end of the rotating rod 61 passes through the control box 51 and has an anti-theft screw hole at its end.

[0035] When installing the clamping plate 71, align the protrusion of the clamping plate 71 with the slot on the receiving plate 54, twist the rotating rod 61, the rotating rod 61 drives the cam 62 to rotate, the protruding section of the cam 62 abuts against the movable plate 64, causing the movable plate 64 to move upward, compressing the spring between the movable plate 64 and the control box 51, the spring passing through the locking rod 52 causes the moving plate 63 to move upward, causing the locking rod 52 to disengage from the locking groove 53, align the locking groove 53 on the clamping plate 71 with the locking rod 52, release the rotating rod 61, the spring between the movable plate 64 and the control box 51 causes the movable plate 64 to move upward. The cam 64 moves downward, causing the flat end of the cam 62 to abut against the movable plate 64. The cam 62 compresses the movable plate 63, causing the locking rod 52 to move downward, so that the locking rod 52 extends into the locking groove 53, thereby fixing the clamping plate 71 to the support column 3. When the glass 72 is damaged, the rotating rod 61 is twisted to move the locking rod 52 away from the locking groove 53 and lift the clamping plate 71, so that the protrusion moves away from the slot, and the clamping plate 71 can be removed from the side of the support column 3. Compared with welded or one-piece molded guardrails, the installation and removal of this guardrail is simple and fast, which can effectively improve the installation and removal efficiency.

[0036] In other feasible embodiments, the movable plate 64 can be fixed inside the control box 51. The movable plate 64 has a groove that matches the cam 62. The locking rod 52 is provided with a spring. The spring between the movable plate 64 and the control box 51 may not be provided. When installing the clamping plate 71, the rotating rod 61 is turned, and the spring causes the locking rod 52 to move upward, aligning the locking groove 53 of the clamping plate 71 with the locking rod 52. The rotating rod 61 is turned again, so that the protruding end of the cam 62 abuts against the groove on the movable plate 64. The cam 62 causes the movable plate 63 to move downward, and the spring is in a compressed state, so the locking rod 52 is inserted into the locking groove 53. Springs are provided between the movable plate 64 and the control box 51 and on the locking rod 52. After aligning the clamping plate 71, it is not necessary to turn the rotating rod 61 again. The spring between the movable plate 64 and the control box 51 can insert the locking rod 52 into the locking groove 53. The installation process is simpler; a spring is only inserted through the locking rod 52. When installing the clamping plate 71, after twisting the rotating rod 61, it is not necessary to maintain the state of the locking rod 52 continuously, and multiple people are not required to cooperate in the installation.

[0037] Reference Figure 2 and Figure 4 A fixing plate 74 is fixedly connected inside the clamping plate 71. The fixing plate 74 is threadedly connected to a glass support plate 73. The glass support plate 73 can be made of plastic, aluminum alloy, etc. A glass support circular support 75 is fixedly connected to the bottom of the clamping plate 71. The glass support plate 73 has a groove that matches the glass support circular support 75. The glass 72 is installed on the glass support plate 73 and fixed with glass glue. A second handrail 8 is also connected to the side of the support column 3. The installation method of the second handrail 8 is the same as that of the first handrail 2.

[0038] When glass 72 is damaged, the common installation method is to install glass 72 on both sides of the support column 3 and fix it with glass glue. When glass 72 is damaged, glass shards are easily adhered to the groove of the support column 3 due to the glass glue. When glass 72 is damaged, the glass support plate 73 can be removed from the clamping plate 71 for replacement, preventing glass shards from falling directly into the groove of the clamping plate 71. The fixing plate 74 and the glass support round support 75 can prevent the glass support plate 73 from loosening with the clamping plate 71, ensuring the firmness of the glass 72 support column 3. The second handrail 8 prevents pedestrians from approaching the edge of the stairs and is also convenient for people of shorter height to use.

[0039] The implementation principle of a prefabricated stair railing according to an embodiment of this application is as follows: During installation, the support column 3 is threaded or welded to the support 1, and the glass 72 is installed inside the glass support plate 73. The groove at the bottom of the glass support plate 73 is aligned with the glass support round support 75, and the glass support plate 73 is fixed to the clamping plate 71 by the fixing plate 74. The rotating rod 61 is twisted to move the locking rod 52 away from the locking groove 53, and one end of the clamping plate 71 abuts against the receiving part. The rotating rod 61 is released, and the moving plate 63 drives the locking rod 52 to extend into the locking groove 53, so that the clamping plate 71 is fixed to the support column 3. The movable support column 3 is adjusted. The angle between the first handrail and the movable rod 42 is adjusted, and the first handrail 2 is inserted into the connecting tube 44 so that the threaded hole at the end of the first handrail 2 is aligned with the double-ended stud 43. The first handrail 2 is then twisted to fix it to the movable rod 42, and the connecting tube 44 is locked to prevent the first handrail 2 from loosening during use. Then, the screws at the movable column head 41 and the movable rod 42 are tightened again to make the first handrail 2 parallel to the inclined surface of the staircase. This stair railing disassembles the integrally formed first handrail 2 into individual parts, reducing the requirements for transportation and safety space, and the installation method is simple, effectively improving installation efficiency.

[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
