Description

Technical Field

[0001] The present invention relates to the technical field of edge protection structures for stairs, and particularly to an adjustable movable edge protection structure for stairs. Background Art

[0002] As an important part of a building, stairs are used for going up and down floors in current high-rise buildings, and it is stipulated that stairs are essential as escape channels in high-rise buildings. Therefore, the design and construction of stairs are indispensable in construction.

[0003] When constructing stairs currently, generally only the stair surface is erected for construction, and structures such as guardrails and handrails of the stairs are carried out in the later decoration project of the construction; when the position of the stairs is within the enclosed passage inside the building, both sides of the stairs are walls, so there is no need to additionally set guardrails; while the position of some stairs is set on the side of the wall, one side is adjacent to the building body, and the other side is suspended. Such stairs need to be separately provided with structures such as guardrails and handrails. However, during the construction of the building body, some suspended parts are only protected by temporary guardrails, which have many potential safety hazards; especially, the bottom of the temporary guardrail cannot cooperate well with the internal corner structure of the stairs, there is a large triangular space, and some building materials may fall from the gap at the internal corner, causing safety accidents.

[0004] It can be seen that there is still room for urgent improvement in the current edge protection structure of stairs, and it is necessary to be improved to enhance the reliability of edge protection, especially to provide good protection for the internal corner position of the edge of the stairs and reduce potential safety hazards. Therefore, a more reasonable technical solution needs to be proposed to solve the technical problems existing in the prior art. Summary of the Invention

[0005] To at least overcome one of the above-mentioned defects, the present invention proposes an adjustable movable edge protection structure for stairs, which protects the internal corner of the stairs through the movable protection structure, avoiding the situation that building materials and other objects fall from the internal corner structure and causing safety accidents. It improves the reliability of the protection structure and ensures safety during construction.

[0006] To achieve the above purpose, the protection structure disclosed by the present invention can adopt the following technical solutions:

[0007] An adjustable movable edge protection structure for stairs, comprising a main protection frame, with a number of outer protection plates and inner protection plates respectively arranged on the inner and outer sides of the main protection frame. The outer protection plates cover the outside of the main protection frame to form an outer protection; the inner protection plates are movable relative to the main protection frame and can be adjusted vertically up and down. When the main protection frame is arranged at the edge of the stairs and forms a triangular gap with the internal corner of the stairs, the inner protection plates descend to block the triangular gap to form an internal protection.

[0008] The protective structure disclosed above is provided with an adjustable inner guard plate, which covers the triangular gap between the protective main frame and the stair surface to avoid gaps on the edge of the stairs for falling materials, thereby improving the safety and reliability of the stair edge protection structure.

[0009] Furthermore, in the present invention, the arrangement of the inner guard plate and the protective main frame is not limited to a single one, and different forms can be adopted in different structures. Here, an optimization is made and one of the feasible options is proposed: the inner guard plate and the protective main frame are matched through an adjustment structure, and the adjustment structure includes an adjustment block that slides and rises along the protective main frame, and a rotating connector disposed on the adjustment block; the rotating connector connects the inner guard plate and deflects in the longitudinal direction, so that the inner guard plate fits and blocks the triangular gap. When such a solution is adopted, the adjustment structure can adjust the height of the inner guard plate, and at the same time adjust the angle of the inner guard plate, so that the inner guard plate can block the triangular gap corresponding to the stairs.

[0010] Furthermore, in some solutions, the inner guard plate and the rotating connector can be set to slide together, so that the inner guard plate can be raised and lowered relative to the rotating structure. This can improve the flexibility and convenience of adjusting the inner guard plate during actual use.

[0011] Furthermore, the connection method of the spiral connector on the protective main frame is not limited to a single method, and it can be implemented by a variety of feasible solutions. Here, we optimize and propose one feasible option: the protective main frame is provided with a slide groove, and the adjustment block slides along the slide groove to achieve lifting; a locking structure is also provided between the adjustment block and the slide groove to lock the adjustment block in a specified position. When such a solution is adopted, the adjustment block slides along the slide groove to achieve longitudinal adjustment, driving the inner guard plate to lift and lower in the longitudinal direction; and when it is lifted and lowered to a suitable position, it is locked by the locking structure to keep the adjustment block fixed in position, thereby keeping the inner guard plate fixed in position.

[0012] The above content describes a stair edge protection structure. The present invention also provides another stair edge protection structure, which is now described.

[0013] A movable and adjustable stair edge protection structure comprises a main protection frame, the main protection frame comprises a plurality of protection units connected in sequence, a connecting unit is arranged between adjacent protection units, and the connecting unit is rotatably connected to the protection unit; a plurality of outer guard plates and inner guard plates are respectively arranged on the inner and outer sides of the main protection frame, the outer guard plates cover the outer side of the main protection frame and form outer side protection; the inner guard plates are movable relative to the main protection frame and can be raised and lowered in the longitudinal direction, and when the main protection frame is arranged at the edge of the stairs and forms a triangular gap with the inner corner of the stairs, the inner guard plates descend and block the triangular gap to form internal protection.

[0014] The edge protection structure of the staircase disclosed herein is provided with a connection unit that can achieve the overlapping of adjacent protection units, facilitating the turning setting and folding storage.

[0015] Furthermore, in the present invention, the setting method of the inner guard plate and the protection main frame is not uniquely limited, and different forms can be adopted in different structures. Here, an optimization is carried out and a feasible option is proposed: the inner guard plate and the protection main frame are cooperated through an adjustment structure. The adjustment structure includes an adjustment block that slides up and down along the protection main frame, and a rotary connector arranged on the adjustment block; the rotary connector is connected to the inner guard plate and deflects longitudinally, so that the inner guard plate fits and blocks the triangular gap. When adopting such a scheme, the adjustment structure can adjust the height of the inner guard plate and also adjust the angle of the inner guard plate, facilitating the inner guard plate to block the triangular gap corresponding to the staircase.

[0016] Still further, in some schemes, a sliding fit can also be set between the inner guard plate and the rotary connector, that is, the lifting adjustment of the inner guard plate relative to the rotary structure can be realized, which can improve the flexibility and convenience of the adjustment of the inner guard plate in the actual use process.

[0017] Furthermore, the connection method of the spiral connector on the protection main frame is not uniquely limited, and it can be realized by a variety of feasible schemes. Here, an optimization is carried out and a feasible option is proposed: a chute is arranged on the protection main frame, and the adjustment block slides along the chute to achieve lifting; a locking structure is also arranged between the adjustment block and the chute to lock the adjustment block at a specified position. When adopting such a scheme, the adjustment block slides along the chute to adjust to achieve the longitudinal adjustment, driving the inner guard plate to lift and lower longitudinally; and when it is lifted to an appropriate position, it is locked by the locking structure to keep the position of the adjustment block fixed, so as to keep the position of the inner guard plate fixed.

[0018] Still further, in the present invention, in order to achieve the folding and overlapping between adjacent protection units, the connection unit needs to be able to achieve the 180° overlapping cooperation of adjacent protection units. Here, an optimization is carried out and a feasible option is proposed: the length of the connection unit is greater than or equal to the thickness of the protection main frame after the outer guard plate and the inner guard plate are set.

[0019] The present invention also provides an edge protection structure that can be adjusted longitudinally, facilitating the adjustment of the protection unit longitudinally to better cooperate with the staircase surface. The following is an explanation:

[0020] A movable and adjustable stair edge protection structure comprises a main protection frame, the main protection frame comprises a plurality of protection units connected in sequence, connecting units are arranged between adjacent protection units, the connecting units are rotatably connected to the protection units, and the connecting units and the protection units slide and cooperate with each other in the longitudinal direction; a plurality of outer guard plates and inner guard plates are respectively arranged on the inner and outer sides of the main protection frame, the outer guard plates cover the outer side of the main protection frame and form outer side protection; the inner guard plates are movable relative to the main protection frame and can be raised and lowered in the longitudinal direction, and when the main protection frame is arranged at the edge of the stairs and forms a triangular gap with the inner corner of the stairs, the inner guard plates descend and block the triangular gap to form internal protection.

[0021] Furthermore, in the present invention, the arrangement of the inner guard plate and the protective main frame is not limited to a single one, and different forms can be adopted in different structures. Here, an optimization is made and one of the feasible options is proposed: the inner guard plate and the protective main frame are matched through an adjustment structure, and the adjustment structure includes an adjustment block that slides and rises along the protective main frame, and a rotating connector disposed on the adjustment block; the rotating connector connects the inner guard plate and deflects in the longitudinal direction, so that the inner guard plate fits and blocks the triangular gap. When such a solution is adopted, the adjustment structure can adjust the height of the inner guard plate, and at the same time adjust the angle of the inner guard plate, so that the inner guard plate can block the triangular gap corresponding to the stairs.

[0022] Furthermore, in some solutions, the inner guard plate and the rotating connector can be set to slide together, so that the inner guard plate can be raised and lowered relative to the rotating structure. This can improve the flexibility and convenience of adjusting the inner guard plate during actual use.

[0023] Furthermore, the connection method of the spiral connector on the protective main frame is not limited to a single method, and it can be implemented by a variety of feasible solutions. Here, we optimize and propose one feasible option: the protective main frame is provided with a slide groove, and the adjustment block slides along the slide groove to achieve lifting; a locking structure is also provided between the adjustment block and the slide groove to lock the adjustment block in a specified position. When such a solution is adopted, the adjustment block slides along the slide groove to achieve longitudinal adjustment, driving the inner guard plate to lift and lower in the longitudinal direction; and when it is lifted and lowered to a suitable position, it is locked by the locking structure to keep the adjustment block fixed in position, thereby keeping the inner guard plate fixed in position.

[0024] Furthermore, in some feasible schemes, the protection unit can be adjusted to directly cooperate with the triangular gap of the stairs, so as to achieve shielding and closure of the edge position, which will result in a stepped structure formed between the tops of adjacent protection units. Therefore, the adjustment block can be adjusted upward to drive the inner guard plate to rise and shield the tops of adjacent protection units to form a smooth and smooth protection structure.

[0025] Compared with the prior art, some beneficial effects of the disclosed technical solution of the present invention include:

[0026] In the present invention, the protective main frame is used as the main supporting structure for the edge of the stairs, and the outer protective plate and the inner protective plate are combined to achieve the protection of the edge of the stairs; in particular, the inner protective plate can be adjusted movably, which can protect and block the triangular gap formed between the protective main frame and the stair surface, forming a complete protective surface for the edge of the stairs, preventing construction materials and the like from falling through the triangular gap, reducing potential safety hazards, and improving the safety and reliability of the protective structure for the edge of the stairs.

[0036] The present invention will be further explained below in conjunction with the drawings and specific embodiments.

[0037] In view of the situation that the edge protection structure of the existing staircase has incomplete protection, which is prone to causing safety accidents due to the falling of materials from the corner position of the staircase, the following embodiments are optimized to overcome the defects existing in the prior art.

[0038] Embodiment 1

[0039] As Figure 1 shown, this embodiment provides a movable adjustable edge protection structure for staircase 6, including a main protection frame 1. A number of outer protection plates 2 and inner protection plates 5 are respectively arranged on the inner and outer sides of the main protection frame 1. The outer protection plates 2 cover the outer side of the main protection frame 1 to form an outer protection; the inner protection plates 5 are movable relative to the main protection frame 1 and are adjusted up and down longitudinally. When the main protection frame 1 is arranged at the edge of the staircase 6 and forms a triangular gap with the corner of the staircase 6, the inner protection plates 5 descend to block the triangular gap to form an inner protection.

[0040] For the protection structure disclosed in this embodiment, by setting the movable adjustable inner protection plates 5, the triangular gap between the main protection frame 1 and the surface of the staircase 6 is blocked and covered by the inner protection plates 5, avoiding the gap for falling materials at the edge of the staircase 6, thereby improving the safety and reliability of the edge protection structure of the staircase 6.

[0041] In this embodiment, the setting method of the inner protection plates 5 and the main protection frame 1 is not uniquely limited, and different forms can be adopted in different structures. This embodiment is optimized and one feasible option is adopted: the inner protection plates 5 and the main protection frame 1 are cooperated through an adjustment structure.

When adopting such a scheme, the adjustment structure can adjust the height of the inner protection plates 5 and can also adjust the angle of the inner protection plates 5, facilitating the inner protection plates 5 to block the triangular gap corresponding to the staircase 6.

[0042] In the natural state, after the main protection frame 1 is set up, the inner protection plates 5 can move downward under the action of gravity and contact the surface of the staircase 6, thereby realizing the blocking of the triangular gap.

[0043] Preferably, all the adjustment blocks 3 cooperate with the main protection frame 1 to realize lifting and lowering. The rotary connector 4 is rotatably connected to the adjustment block 3 and can realize 360° longitudinal rotation, thereby driving the inner protection plates 5 to adjust the angle.

[0044] Preferably, the rotary connector 4 can be fixedly connected to the inner protection plates 5 through a number of bolts.

[0045] In some feasible embodiments, a sliding fit can also be provided between the inner guard plate 5 and the rotary connector 4, so as to realize the lifting adjustment of the inner guard plate 5 relative to the rotating structure, which can improve the adjustment flexibility and convenience of the inner guard plate 5 during actual use.

[0046] The connection method of the spiral connector on the main protection frame 1 is not uniquely limited, and it can be realized by a variety of feasible solutions. This embodiment is optimized and one of the feasible options is adopted: a chute is provided on the main protection frame 1, and the adjusting block 3 slides along the chute to realize lifting; a locking structure is also provided between the adjusting block 3 and the chute to lock the adjusting block 3 at a specified position. When adopting such a solution, the adjusting block 3 slides along the chute to adjust to realize the longitudinal adjustment, driving the inner guard plate 5 to lift and lower longitudinally; and when it is lifted to an appropriate position, it is locked by the locking structure to keep the position of the adjusting block 3 fixed, so as to keep the position of the inner guard plate 5 fixed.

[0047] Preferably, the locking structure can adopt a tightening screw structure, that is, a threaded hole is provided on the adjusting block 3, and a tightening screw is fitted in the threaded hole. When the adjusting block 3 slides along the chute to a specified position, the tightening screw is rotated to tighten the chute so as to fix the sliding block at the specified position.

[0049] The content of Embodiment 1 describes a structure for protecting the edge of a staircase 6. This embodiment also provides another edge protection structure, which will be described now.

[0050] As Figures 2 to 4 shown, this embodiment provides a movable adjustable edge protection structure for a staircase 6, including a main protection frame 1. The main protection frame 1 includes a number of protection units connected in sequence, and a connection unit 7 is provided between adjacent protection units. The connection unit 7 is rotatably connected to the protection unit; a number of outer guard plates 2 and inner guard plates 5 are respectively provided on the inner and outer sides of the main protection frame 1. The outer guard plates 2 cover the outside of the main protection frame 1 to form an outer protection; the inner guard plate 5 is movable relative to the main protection frame 1 and is adjusted to lift and lower longitudinally. When the main protection frame 1 is arranged at the edge of the staircase 6 and forms a triangular gap with the inner corner of the staircase 6, the inner guard plate 5 descends to block the triangular gap to form an inner protection.

[0051] For the edge protection structure of the staircase 6 disclosed in this embodiment, the provided connection unit 7 can realize the superposition of adjacent protection units, which is convenient for turning setting and folding storage.

[0052] The difference from Embodiment 1 is that through the movable connection of the connection unit 7, the edge protection of the staircase 6 with a turning inclination angle can be realized, and at the same time, it can be folded and stored after disassembly, greatly improving the flexibility of use and the convenience of disassembly and assembly.

[0053] In this embodiment, in order to achieve the folding and overlapping between adjacent protection units, it is required that the connecting unit 7 can achieve the overlapping and matching of adjacent protection units at 180°. Here, an optimization is carried out and a feasible option is proposed: the length of the connecting unit 7 is greater than or equal to the thickness of the protection main frame 1 after the outer protection plate 2 and the inner protection plate 5 are provided.

[0054] Preferably, the connecting unit 7 includes a square connecting frame 701. The two sides of the connecting frame 701 are respectively hinged to the protection unit, and a connecting protection plate 702 is further provided inside the connecting frame 701.

[0055] In this embodiment, the setting method of the inner protection plate 5 and the protection main frame 1 is not uniquely limited, and different forms can be adopted in different structures. Here, an optimization is carried out and a feasible option is proposed: the inner protection plate 5 and the protection main frame 1 are matched through an adjusting structure. The adjusting structure includes an adjusting block 3 that slides and lifts along the protection main frame 1, and a rotary connector 4 provided on the adjusting block 3; the rotary connector 4 is connected to the inner protection plate 5 and deflects longitudinally, so that the inner protection plate 5 fits and blocks the triangular gap. When such a solution is adopted, the adjusting structure can adjust the height of the inner protection plate 5 and also adjust the angle of the inner protection plate 5, which is convenient for the inner protection plate 5 to block the triangular gap corresponding to the staircase 6.

[0056] In the natural state, after the protection main frame 1 is set up, the inner protection plate 5 can move downward under the action of gravity and contact the surface of the staircase 6, so as to block the triangular gap.

[0057] Preferably, all the adjusting blocks 3 cooperate with the protection main frame 1 to achieve lifting and lowering. The rotary connector 4 is rotatably connected to the adjusting block 3 and can achieve a 360° longitudinal rotation, so as to drive the inner protection plate 5 to adjust the angle.

[0058] Preferably, the rotary connector 4 can be fixedly connected to the inner protection plate 5 by a plurality of bolts.

[0059] In some feasible embodiments, a sliding fit can also be provided between the inner protection plate 5 and the rotary connector 4, that is, the lifting adjustment of the inner protection plate 5 relative to the rotating structure can be achieved, which can improve the flexibility and convenience of the adjustment of the inner protection plate 5 during actual use.

[0060] The connection method of the spiral connector on the main protection frame 1 is not uniquely limited, and it can be realized by various feasible solutions. In this embodiment, optimization is carried out and one of the feasible options is adopted: a chute is provided on the main protection frame 1, and the adjusting block 3 slides along the chute to realize lifting; a locking structure is also provided between the adjusting block 3 and the chute to lock the adjusting block 3 at a specified position. When adopting such a solution, the adjusting block 3 slides along the chute to adjust and realizes the longitudinal adjustment, driving the inner protective plate 5 to lift and lower longitudinally; and when it is lifted to an appropriate position, it is locked by the locking structure to keep the position of the adjusting block 3 fixed, so as to keep the position of the inner protective plate 5 fixed.

[0061] Preferably, the locking structure can adopt a pressing screw structure, that is, a threaded hole is provided on the adjusting block 3, and a pressing screw is fitted in the threaded hole. When the adjusting block 3 slides along the chute to a specified position, the pressing screw is rotated to press against the chute so as to fix the sliding block at the specified position.

[0062] Embodiment 3

[0063] This embodiment also provides an edge protection structure, which can be adjusted longitudinally, facilitating the adjustment of the protection unit longitudinally so as to better cooperate with the surface of the staircase 6. The following is an explanation:

[0064] As Figure 5 、 Figure 6 shown, a movable adjustable edge protection structure for the staircase 6 includes a main protection frame 1, the main protection frame 1 includes a number of protection units connected in sequence, a connection unit 7 is provided between adjacent protection units, the connection unit 7 is rotatably connected to the protection unit, and the connection unit 7 is slidably matched with the protection unit longitudinally; a number of outer protection plates 2 and inner protection plates 5 are respectively provided on the inner and outer sides of the main protection frame 1, the outer protection plates 2 cover the outside of the main protection frame 1 and form an outer protection; the inner protection plates 5 are movable relative to the main protection frame 1 and are adjusted to lift and lower longitudinally. When the main protection frame 1 is arranged at the edge of the staircase 6 and forms a triangular gap with the internal angle of the staircase 6, the inner protection plate 5 descends and blocks the triangular gap to form an internal protection.

[0065] Through the movable connection of the connection unit 7, the edge protection of the staircase 6 with a steering inclination angle can be realized, and at the same time, it can be folded and stored after being disassembled, greatly improving the flexibility of use and the convenience of disassembly and assembly.

[0066] In this embodiment, in order to realize the folding and overlapping between adjacent protection units, it is required that the connection unit 7 can realize the 180° overlapping cooperation of adjacent protection units. Here, optimization is carried out and one of the feasible options is proposed: the length of the connection unit 7 is greater than or equal to the thickness of the main protection frame 1 after the outer protection plate 2 and the inner protection plate 5 are provided.

[0067] Preferably, the connection unit 7 includes a square connection frame 701. The two sides of the connection frame 701 are respectively hinged to the protection unit, and a connection protection plate 702 is further arranged inside the connection frame 701.

[0068] Preferably, in this embodiment, a sliding buckle 8 is sleeved on the connection frame 701. The sliding buckle 8 slides longitudinally up and down along the connection frame 701, and the sliding buckle 8 is hinged to the protection unit to realize flipping and folding.

[0069] In this embodiment, the setting manner of the inner protection plate 5 and the protection main frame 1 is not uniquely limited, and different forms can be adopted in different structures. This embodiment is optimized and one feasible option is adopted: the inner protection plate 5 and the protection main frame 1 are matched through an adjustment structure. The adjustment structure includes an adjustment block 3 that slides up and down along the protection main frame 1, and a rotary connection head 4 arranged on the adjustment block 3; the rotary connection head 4 is connected to the inner protection plate 5 and deflects longitudinally, so that the inner protection plate 5 fits and blocks the triangular gap. When adopting such a solution, the adjustment structure can adjust the height of the inner protection plate 5 and can also adjust the angle of the inner protection plate 5, which is convenient for the inner protection plate 5 to block the triangular gap corresponding to the staircase 6.

[0070] In the natural state, after the protection main frame 1 is set up, the inner protection plate 5 can move downward under the action of gravity and contact the surface of the staircase 6, so as to realize the blocking of the triangular gap.

[0071] Preferably, all the adjustment blocks 3 cooperate with the protection main frame 1 to realize lifting and lowering. The rotary connection head 4 is rotatably connected to the adjustment block 3 and can realize 360° longitudinal rotation, so as to drive the inner protection plate 5 to adjust the angle.

[0072] Preferably, the rotary connection head 4 can be fixedly connected to the inner protection plate 5 through a plurality of bolts.

[0073] In some feasible embodiments, the inner protection plate 5 and the rotary connection head 4 can also be set to be in sliding fit, that is, the lifting adjustment of the inner protection plate 5 relative to the rotation structure can be realized, which can improve the adjustment flexibility and convenience of the inner protection plate 5 during actual use.

[0074] The connection method of the spiral connector on the main protection frame 1 is not uniquely defined, and it can be implemented by a variety of feasible solutions. In this embodiment, it is optimized and one of the feasible options is adopted: a chute is provided on the main protection frame 1, and the adjusting block 3 slides along the chute to achieve lifting and lowering; a locking structure is also provided between the adjusting block 3 and the chute to lock the adjusting block 3 at a specified position. When adopting such a solution, the adjusting block 3 slides along the chute to adjust and realizes the longitudinal adjustment, driving the inner protective plate 5 to lift and lower longitudinally; and when it is lifted to an appropriate position, it is locked by the locking structure to keep the position of the adjusting block 3 fixed, so as to keep the position of the inner protective plate 5 fixed.

[0075] Preferably, the locking structure can adopt a tightening screw structure, that is, a threaded hole is provided on the adjusting block 3, and a tightening screw is fitted in the threaded hole. When the adjusting block 3 slides along the chute to a specified position, the tightening screw is rotated to tighten the chute so as to fix the sliding block at the specified position.

[0076] In some feasible solutions, the protection unit can be adjusted to directly cooperate with the triangular gap of the staircase 6, so as to realize the occlusion and enclosure of the edge position. This will result in a stepped structure being formed between the tops of adjacent protection units. Therefore, the adjusting block 3 can be adjusted upward, driving the inner protective plate 5 to rise and occluding the tops of adjacent protection units to form a smooth and flat protection structure.

[0077] The above are the implementation manners listed in this embodiment, but this embodiment is not limited to the above optional implementation manners. Those skilled in the art can arbitrarily combine the above manners to obtain many other implementation manners, and anyone can obtain various other forms of implementation manners under the inspiration of this embodiment. The above specific implementation manners should not be understood as limiting the protection scope of this embodiment, and the protection scope of this embodiment should be defined by the claims.
