Description

Technical Field

[0001] This utility model relates to the field of building railing technology, specifically a building railing. Background Technology

[0002] Construction railings are safety protection facilities used in construction sites, roads, balconies, and other areas. They are typically made of materials such as steel pipes, steel mesh, or aluminum alloys. Their structural design meets safety standards and can effectively isolate dangerous areas, prevent people from falling or objects from falling, and ensure the safety of construction workers and pedestrians.

[0003] Traditional welded connections for building railings have significant maintenance drawbacks. Because the protective bars used for shielding and blocking in building railings need to balance cost and weight, they typically use thinner diameter bars, resulting in a high damage rate over long-term use. Current welded fixing methods require destructive removal for replacement: 1. Damaged bars need to be cut using an angle grinder; 2. Re-welding requires grinding the contact surfaces and precise alignment; 3. Welding generates sparks, posing a safety hazard. Furthermore, replacing a single protective bar is time-consuming, requires a professional welder, and is not convenient; multiple welds weaken the beam structure, accelerating the overall railing's lifespan. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a building railing that can effectively solve the technical problem that the thin guardrails in the existing building railings are not easy to disassemble and replace individually.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model discloses a building railing, including support columns, two sets of which are symmetrically arranged. Two sets of mounting beams are longitudinally arranged between the two sets of support columns. Multiple guardrails are installed between the two sets of mounting beams. A mounting seat is provided on the inner side of each mounting beam. Locking caps are installed at both ends of each guardrail. The locking caps are slidably fitted onto the guardrails and threadedly locked to the corresponding mounting seats. An installation cavity is formed inside the mounting beam to cooperate with the mounting seats. A limiting piece is elastically slidably connected in the installation cavity. A limiting post is fixedly installed at the end of the limiting piece near the locking cap. A limiting groove is formed at the end of the locking cap near the limiting post. The limiting post slides to the outside of the mounting beam and engages with the limiting groove. A retraction component is installed on the mounting beam in cooperation with the limiting post.

[0006] Preferably, a spring is installed between the outer side of the limiting piece and the inner wall of the mounting cavity. The spring provides a restoring force to the limiting piece, so that the limiting post can be stably positioned in the limiting groove when there is no external interference, thereby achieving the locking cap limiting.

[0007] Preferably, the side of the limiting piece has a limiting slider, and the side wall of the mounting cavity is provided with a limiting groove. The cooperation of the limiting slider and the limiting groove can improve the movement stability of the limiting piece in the mounting cavity, thereby making the movement of the limiting post more stable and precise.

[0008] Preferably, the retraction assembly includes a movable frame that is slidably mounted on the mounting beam. A first magnetic block is engaged on the movable frame, and a second magnetic block is mounted on the limiting plate. The first and second magnetic blocks are magnetically attracted to each other. When installing the locking cap, the first magnetic block can be moved to the outside of the corresponding limiting plate under the action of the movable frame. This allows the first and second magnetic blocks to cooperate under the action of magnetic attraction, overcoming the spring force, so that the limiting post can be retracted into the mounting cavity. This enables convenient screwing of the locking cap. After the locking cap is screwed and fixed, the movable frame is removed. Under the action of the spring, the limiting plate can drive the limiting post to extend out of the mounting beam again and engage with the corresponding limiting groove. This restricts the arbitrary rotation of the locking cap and prevents the locking cap from becoming loose or being arbitrarily disassembled. Here, when not in use, the first magnetic block can be removed from the movable frame.

[0009] Preferably, the mounting beam has a movable groove, and the inner side of the movable frame has a movable slider. The movable slider slides within the movable groove. The movable groove and the movable slider work together to achieve a limited sliding installation of the movable frame on the mounting beam. The movable groove and the movable slider can achieve friction locking when there is no external force.

[0010] Preferably, the mounting base has a locking groove on one side, and the top of the protective rod has a locking block. The locking block slides and engages with the locking groove. During installation, the locking block at the end of the protective rod is engaged into the corresponding locking groove, thereby achieving rapid positioning of the protective rod when installed between the two sets of mounting bases, improving installation accuracy, convenience, and stability.

[0011] Preferably, the bottom end of the support column is equipped with a movable wheel, and a locking frame is slidably mounted on the support column. The bottom end of the locking frame has a locking lug. The movable wheel facilitates the movement of the entire structure. When it is necessary to fix the entire structure, the locking frame can be moved downward from the support column so that the locking lug at the bottom end of the locking frame contacts the ground. The locking lug has a fixing hole structure, which can cooperate with external ground nails to connect and fix the locking lug to the building ground, thereby improving the stability of the entire structure during use.

[0012] Preferably, the inner side of the locking frame has a connecting slider, and the side of the support column has a connecting groove. The connecting slider and the connecting groove are slidably engaged. Through the engagement of the connecting slider and the connecting groove, the locking frame can be adjusted and installed by sliding up and down on the support column. Thus, when moving, the locking frame can slide up and off the ground, which facilitates the overall movement. Here, the connecting slider and the connecting groove can be frictionally locked when there is no external force.

[0013] Compared with known public technologies, the technical solution provided by this utility model has the following beneficial effects: 1. This utility model achieves modular design of building railings through a detachable guardrail structure, significantly improving maintenance efficiency. The guardrail ends are connected to the mounting base via threaded locking caps, and the quick positioning of the locking blocks and slots simplifies the installation process. When a section of the guardrail is damaged, the locking cap can be unscrewed for individual replacement simply by using the magnetic suction assembly controlled by the moving frame to release the locking post, eliminating the need for welding or overall disassembly. This design not only reduces labor and time costs but also minimizes material waste and avoids damage to the beam structure. Furthermore, the automatic reset function of the locking posts and slots effectively prevents unauthorized disassembly by non-professionals, balancing convenience and safety.

[0014] 2. This utility model adds double safety to the easily loosened threaded connection by the synergistic action of the limiting plate, spring, limiting post, and limiting groove. After the locking cap is tightened, the spring drives the limiting post to engage with the limiting groove, forming a mechanical lock; while the first magnetic block on the moving frame requires manual operation to release the lock, avoiding accidental loosening caused by vibration. The cooperation between the limiting slider and the groove further improves the stability of the limiting post's movement, ensuring a durable and reliable locked state.

[0015] 3. In this utility model, the combination of movable wheels at the bottom of the support column and a liftable locking frame gives the building railing excellent mobility and stability. When moving, the locking frame slides up and off the ground, and can be easily pushed by the movable wheels; when fixing, the locking frame is lowered so that the locking ears contact the ground, and can be firmly anchored with ground nails. The friction locking mechanism connecting the slider and the groove simplifies the height adjustment operation and requires no additional tools. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to embodiments. Please refer to the embodiments. Figures 1-6 .

[0020] The aforementioned construction railing includes support posts 1, with two sets of support posts symmetrically arranged. Two sets of mounting beams 2 are longitudinally arranged between the two sets of support posts 1. Multiple guardrails 3 are installed between the two sets of mounting beams 2. Mounting seats 4 are provided on the inner side of the mounting beams 2. Locking caps 5 are installed at both ends of the guardrails 3. The locking caps 5 are slidably fitted onto the guardrails 3 and threadedly locked with the corresponding mounting seats 4. The mounting beams 2 have mounting cavities 6 that cooperate with the mounting seats 4. Limiting plates 7 are elastically slidably connected in the mounting cavities 6. A limiting post 8 is fixedly installed at the end of the limiting plate 7 near the locking cap 5. A limiting groove 9 is opened at the end of the locking cap 5 near the limiting post 8. The limiting post 8 slides to the outer side of the mounting beams 2 and engages with the limiting groove 9. A retraction component is installed on the mounting beams 2 in cooperation with the limiting post 8.

[0021] Please see Figures 1-6 As one implementation of the limiting piece 7: a spring 10 is installed between the outer side of the limiting piece 7 and the inner wall of the mounting cavity 6. The spring 10 provides a restoring force to the limiting piece 7, so that the limiting post 8 can be stably located in the limiting groove 9 when there is no external force interference, thereby realizing the limiting of the locking cap 5.

[0022] In this utility model, the side of the limiting piece 7 has a limiting slider 11, and the side wall of the mounting cavity 6 is provided with a limiting groove 12. The cooperation of the limiting slider 11 and the limiting groove 12 can improve the movement stability of the limiting piece 7 in the mounting cavity 6, thereby making the movement of the limiting post 8 more stable and precise.

[0023] Please see Figures 1-6 As one embodiment of the shrink-fit assembly: the shrink-fit assembly includes a movable frame 13, which is slidably mounted on the mounting beam 2. A first magnetic block 14 is engaged on the movable frame 13. The first magnetic block 14 can be detachably engaged on the movable frame 13 by friction locking. A second magnetic block 15 is mounted on the limiting plate 7. The first magnetic block 14 and the second magnetic block 15 are magnetically attracted to each other. When installing the locking cap 5, the first magnetic block 14 can be moved to the outside of the corresponding limiting plate 7 under the action of the movable frame 13, so that the first magnetic block 14 and the second magnetic block 15 cooperate under the action of magnetic attraction to overcome the spring. The elastic force of the spring 10 allows the limiting post 8 to retract into the mounting cavity 6, thereby enabling the locking cap 5 to be easily screwed on. After the locking cap 5 is screwed on and fixed, the moving frame 13 is removed. Under the action of the spring 10, the limiting piece 7 can drive the limiting post 8 to extend out of the mounting beam 2 again and engage with the corresponding limiting groove 9, thereby restricting the arbitrary rotation of the locking cap 5 and preventing the locking cap 5 from becoming loose or being arbitrarily disassembled. Here, when not in use, the first magnetic block 14 can be removed from the moving frame 13. The first magnetic block 14 can be made of neodymium iron boron magnet, preferably with a magnetic attraction force 1.2-1.5 times that of the elastic force of the spring 10.

[0024] Please see Figures 1-6 As one embodiment of the mounting beam 2: the mounting beam 2 is provided with a movable slide groove 16, and the inner side of the movable frame 13 is provided with a movable slider 17. The movable slider 17 is slidably located in the movable slide groove 16. Through the cooperation of the movable slide groove 16 and the movable slider 17, the movable frame 13 can be limited and slidably installed on the mounting beam 2. The movable slide groove 16 and the movable slider 17 can be frictionally locked when there is no external force.

[0025] Please see Figures 1-6As one implementation of the mounting base 4: a locking groove 18 is provided on one side of the mounting base 4, and a locking block 19 is provided at the top of the protective rod 3. The locking block 19 is slidably locked with the locking groove 18. During installation, the locking block 19 at the end of the protective rod 3 is locked into the corresponding locking groove 18, thereby realizing the quick positioning of the protective rod 3 when it is installed between the two sets of mounting bases 4, improving the installation accuracy, convenience and stability.

[0026] Please see Figures 1-6 As one implementation of the support column 1: a movable wheel 20 is installed at the bottom end of the support column 1, and a locking frame 21 is slidably installed on the support column 1. The bottom end of the locking frame 21 has a locking ear 22. The movable wheel 20 facilitates the movement of the whole. When it is necessary to fix the whole, the locking frame 21 can be moved downward from the support column 1 so that the locking ear 22 at the bottom end of the locking frame 21 contacts the ground. The locking ear 22 has a fixing hole structure, which can cooperate with external ground nails, etc. to connect and fix the locking ear 22 to the building ground, thereby improving the stability of the whole during use.

[0027] Please see Figures 1-6 As one embodiment of the locking frame 21: the inner side of the locking frame 21 has a connecting slider 23, and the side of the support column 1 has a connecting groove 24. The connecting slider 23 and the connecting groove 24 are slidably engaged. Through the engagement of the connecting slider 23 and the connecting groove 24, the locking frame 21 can be adjusted and installed by sliding up and down on the support column 1. Thus, when moving, the locking frame 21 can slide up and off the ground, which facilitates the overall movement. Here, the connecting slider 23 and the connecting groove 24 can be frictionally locked when there is no external force.

[0028] The complete working principle and steps of the above embodiments are as follows: This utility model provides a detachable protective rod 3, which facilitates the installation and removal of the protective rod 3. During installation, the locking block 19 at the end of the guard rod 3 is locked into the corresponding locking groove 18, thereby achieving quick positioning of the guard rod 3 when it is installed between the two sets of mounting seats 4; Then, tighten the locking cap 5 so that the locking cap 5 cooperates with the mounting base 4 to lock and fix the locking cap 5 and the mounting base 4, thereby achieving the locking and fixing of the protective rod 3 and the mounting base 4. During this process, the moving frame 13 controls the first magnetic block 14 to be located outside the corresponding mounting base 4, so that the first magnetic block 14 and the second magnetic block 15 cooperate under the action of magnetic attraction to overcome the elastic force of the spring 10 and drive the limiting post 8 to be retracted into the mounting cavity 6. At this time, the magnetic attraction force generated by the first magnetic block 14 and the second magnetic block 15 is greater than the elastic force of the spring 10, thereby realizing the convenient screwing of the locking cap 5. After the locking cap 5 is screwed and fixed, the moving frame 13 is removed to remove the magnetic attraction. Under the action of the spring 10, the limiting piece 7 can be driven to move the limiting post 8 to reset, extend the mounting beam 2 again, and engage with the corresponding limiting groove 9. This can limit the arbitrary rotation of the locking cap 5 and prevent the locking cap 5 from becoming loose or being arbitrarily disassembled. When disassembling, simply reverse the steps described above. This utility model facilitates the flexible installation and disassembly of the guardrail 3 in building railings, thereby making it easy to replace the guardrail 3 that is partially damaged, saving maintenance costs. Furthermore, the combination of structures such as the limiting post 8, limiting plate 7, limiting groove 9, first magnetic block 14, and second magnetic block 15 can prevent the locking cap 5 from being twisted or loosened at will, which could lead to the guardrail 3 becoming loose or being disassembled at will, thus improving the installation protection.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
