Description

Technical Field

[0001] This invention relates to the field of construction scaffolding, specifically to an edge protection device for building construction. Background Technology

[0002] Since roof construction involves working at heights, certain safety protections are necessary for personnel. Currently, there are two main forms of protection for sloping roof construction: one is using external scaffolding, and the other is installing protective barriers by embedding steel pipes or using expansion bolts. Because the protective devices do not have an expandable or retractable function, the structure of the protective device cannot be changed after installation, regardless of the fixing method. When it is necessary to install other functional components (install water pipes or embedded structural components on the external wall) or add an extra processing platform, the protective device must be removed directly from the wall. After the phase of work is completed, the protective device must be reinstalled. This construction process is not only time-consuming, but also leaves repeated broken holes from the expansion bolts on the wall surface. Summary of the Invention

[0003] This invention provides an edge protection device for building construction, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this invention to solve its technical problem is: An edge protection device for building construction includes a fixed frame, side panels, and a movable baffle. The fixed frame and side panels are symmetrically arranged. The upper and lower ends of the two fixed frames are provided with connecting shafts. The upper and lower ends of the two side panels are connected to the fixed frame through the connecting shafts. The movable baffle is arranged between the two side panels. When the two side panels are closed, the movable baffle is covered. The upper end of the side fan is provided with a second sliding groove, and a first rotating shaft is provided in the second sliding groove. The two first rotating shafts are connected by a connecting rod. When the two side fans are unfolded, the connecting rod slides away from the fixed frame to the end of the second sliding groove. The surface of the side fan is provided with a first sliding groove, and the movable baffle is slidably connected to the first sliding groove through the movable connecting shafts provided on both sides of its upper end. A movable support rod is installed on the side of the movable baffle close to the fixed frame. The movable support rod is driven to swing by a traction mechanism. When the movable support rod swings to be parallel to the slide groove, it is fixed to the surface of the fixed frame by a support block, and the movable baffle moves to the end of the slide groove away from the fixed frame. Both side sashes have windows on their surfaces, and movable sash plates are installed inside the windows. The movable sash plates are connected by hinges on both sides at their lower ends. Both movable sash plates have slots on their surfaces, and the two slots form a limiting groove. A fixing component is installed in the limiting groove. Both the fixing component and the slots are T-shaped structures.

[0005] In a preferred embodiment, a magnetic sheet is provided at the end of the movable fan plate away from the window, and a corresponding metal lug is provided inside the window. When the movable fan plate swings into the window, the movable fan plate is fixed to the surface of the metal lug by magnetic adsorption.

[0006] In a preferred embodiment, the fixing member includes a wedge, an L-plate, and a vertebral plate. The wedge and the L-plate are symmetrically arranged on both sides of the vertebral plate. The wedge is positioned closer to the vertebral plate than the L-plate. The two wedges form a wedge groove with an included angle through the inclined surfaces of their adjacent surfaces, and the vertebral plate is embedded in the wedge groove. The L-plate, wedge, and vertebral plate are sequentially inserted into the L-plate.

[0007] In a preferred embodiment, the surface of the support block near the movable support rod is provided with an arc-shaped surface, and the arc-shaped surface is adapted to the outer wall contour of the movable support rod. When the movable support rod swings to be parallel to the slide groove, the outer wall of the movable support rod fits against the arc-shaped surface, and the support block is locked to the surface of the fixed frame by bolts.

[0008] In a preferred embodiment, a pad is provided on the side of the fixed frame away from the movable baffle. The pad is fixed to the wall by bolts provided on the surface of the fixed frame, and the traction mechanism passes through the pad from bottom to top.

[0009] A preferred technical solution is that the traction mechanism includes a traction rope and a rotating winding column fixed to the upper end of the pad. An arc-shaped block is provided at the upper end of the fixed frame. One end of the traction rope is connected to the surface of the movable support rod, and the other end passes through the arc-shaped block, the pad, and the rotating winding column in sequence before being wound around the surface of the rotating winding column. A groove for the traction rope to pass through is provided inside the rotating winding column. The groove consists of a winding part and a threading part. The winding part is provided on the surface of the rotating winding column, and the threading part is provided inside the rotating winding column. The winding part is spirally arranged, and one end of the winding part is provided on the surface of the rotating winding column, while the other end extends into the rotating winding column and communicates with the threading part. The threading part extends to the lower end face of the rotating winding column. The rotating winding column is threadedly connected to the pad, and a rocker arm is provided at the upper end of the rotating winding column. When the traction rope passes through the threading part and is wound around the surface of the winding part, the length of the traction rope wound around the surface of the winding part can be increased by rotating the winding column.

[0010] Compared with existing technologies, this technical solution has the following advantages: The protective device of this invention enables the free opening and closing of the side sash through the linkage between the traction mechanism and the movable support rod. After the side sash is opened, the movable sash plate on the surface of the side sash is opened inward to form a construction platform supporting the construction personnel. After the movable sash plate is opened, the window is open, which can provide a passage for the construction personnel and increase the working space. When special operations require a corresponding working space, the entire protective device can be stored by simply reversing the operation. Attached Figure Description

Detailed Implementation

[0025] like Figures 1 to 12 As shown, the present invention proposes an edge protection device for building construction, including a fixed frame 1, side panels 2 and a movable baffle 3. The fixed frame 1 and the side panels 2 are symmetrically arranged. The upper and lower ends of the two fixed frames 1 are provided with connecting shafts 14. The upper and lower ends of the two side panels 2 are connected to the fixed frame 1 through the connecting shafts 14. The movable baffle 3 is arranged between the two side panels 2. When the two side panels 2 are closed, the movable baffle 3 is covered. The upper end of the side fan 2 is provided with a second sliding groove 26, and a first rotating shaft is provided in the second sliding groove 26. The two first rotating shafts are connected by a connecting rod 4. When the two side fans 2 are unfolded, the connecting rod 4 slides away from the fixed frame 1 to the end of the second sliding groove 26. The surface of the side fan 2 is provided with a first sliding groove 22. The movable baffle 3 is slidably connected to the first sliding groove 22 through the movable connecting shafts 33 provided on both sides of its upper end. The movable baffle 3 is installed on the side of the fixed frame 1 close to the movable baffle 1. The movable support rod 31 is driven to swing by a traction mechanism. When the movable support rod 31 swings to be parallel to the first sliding groove 22, it is fixed to the surface of the fixed frame 1 by a support block 13, and the movable baffle 3 moves to the end of the first sliding groove 22 away from the fixed frame 1. In its initial closed state, the two side fans 2 are parallel and attached to both sides of the fixed frame 1, and the movable baffle 3 is covered inside the side fans 2. The whole device has a flat and folded shape, which is convenient for storage or does not take up too much space when not in use.

[0026] During the protective deployment operation, the construction workers first stand in a safe position on the roof, holding the outer edges of the two side panels 2 with both hands and applying an outward horizontal pushing force. The two side panels 2 rotate synchronously outward around the vertical axis of the fixed frame 1, with their connecting shafts 14 at their upper and lower ends as the center of rotation. As the side panels 2 gradually open, the connecting rods 4 installed in the upper sliding grooves 26 of the two side panels 2 begin to move—the rotating shafts at both ends of the connecting rod 4 respectively embed into the corresponding sliding grooves 26. Under the displacement caused by the rotation of the side panels 2, the rotating shafts slide slowly along the track direction of the sliding grooves 26 from the end closer to the fixed frame 1 to the end farther away from the fixed frame 1. The construction workers continue to push the side panels 2 until the rotating shafts at both ends of the connecting rod 4 simultaneously reach the end position of the sliding grooves 26. At this point, the connecting rod 4 is tightened and spans between the tops of the two side panels 2, providing rigid support and limiting the side panels 2 from continuing to rotate outward. The deployment angle reaches the maximum design value, forming a stable protective facade.

[0027] After the side panel 2 is fully extended, the construction workers operate a traction mechanism, such as a manual winch or a push-pull handle, to drive the movable support rod 31 to swing around its connection point with the movable baffle 3. Observing the swing direction of the movable support rod 31, they swing it from an inclined state to a horizontal state parallel to the slide groove on the surface of the side panel 2. Then, they push the end of the movable support rod 31 into the slot of the support block 13 fixed to the surface of the fixed frame 1 to complete the locking. During this process, the movable connecting shafts 33 on both sides of the upper end of the movable baffle 3 are pushed by the movable support rod 31 and slide along the slide groove from the end closest to the fixed frame 1 to the outer end away from the fixed frame 1 until the movable connecting shafts 33 reach the end of the slide groove. The movable baffle 3 then extends completely and together with the two side panels 2, forms a complete continuous protective surface. The entire operation is completed by manual pushing, pulling, and locking, without the need for additional lifting equipment or any drilling or pre-embedding work on the wall.

[0028] Both side panels 2 have windows 23 on their surfaces. Movable sash plates 21 are installed inside the windows 23. The movable sash plates 21 are connected by hinges 25 on both sides of their lower ends. Both movable sash plates 21 have slots 212 on their surfaces. The two slots 212 form a limiting groove. A fixing member 211 is installed in the limiting groove. Both the fixing member 211 and the slots 212 are T-shaped structures. A magnetic sheet 213 is provided at the end of the movable sash plate 21 away from the window 23. A corresponding metal lug 24 is provided inside the window 23. When the movable sash plate 21 swings into the window 23, it is fixed by adsorbing onto the surface of the metal lug 24 through the magnetic sheet 213. When the movable sash plate 21 is retracted into the window 23, it is fixed by the adsorption effect between the magnetic sheet 213 and the metal lug 24.

[0029] Furthermore, the fixing member 211 includes a wedge 2111, an L-plate 2112, and a vertebral plate 2113. The wedge 2111 and the L-plate 2112 are symmetrically arranged on both sides of the vertebral plate 2113. The wedge 2111 is arranged closer to the vertebral plate 2113 than the L-plate 2112. The two wedges 2111 form a wedge groove with an included angle through the inclined surfaces of their adjacent surfaces. The vertebral plate 2113 is embedded in the wedge groove. The L-plate 2112, the wedge 2111, and the vertebral plate 2113 are sequentially installed into the L-plate 2112. First, the assembled fastener 211 is inserted into the T-shaped limiting groove formed by the two slots 212. At this time, the wedge block 2111 and the L plate 2112 are in a relaxed state without expansion within the limiting groove. Then, the operator pushes or taps the vertebral plate 2113 deeper into the wedge groove. As the vertebral plate 2113 moves forward along the wedge groove, its two sides slide relative to the inclined surfaces of the two wedge blocks 2111 and apply a lateral thrust. Since the wedge groove gradually narrows along the forward direction, the vertebral plate 2113 forces the two wedge blocks 2111 to push them simultaneously to both sides perpendicular to the forward direction during the forward movement. The pushed wedge blocks 2111 then transmit the thrust to the L plate 2112 located on its outer side, causing the two L plates 2112 to open outward and press tightly against the inner wall of the limiting groove, generating a tension friction force. The deeper the vertebral plate 2113 is pushed in, the greater the outward movement of the wedge block 2111, and the greater the positive pressure of the L-plate 2112 on the wall of the limiting groove. This locks the fixing member 211 and the limiting groove into a rigid whole with no relative movement. The lateral tension prevents the upper ends of the two movable fan plates 21 from displacing or separating along the hinge 25 flipping direction or horizontal direction. When unlocking is required, simply knock or pull out the vertebral plate 2113 in the opposite direction to remove it from the wedge groove. After losing the inclined plane pushing force, the wedge block 2111 and the L-plate 2112 automatically retract inward to reset. The tension disappears, and the fixing member 211 can be easily pulled out of the limiting groove, and the two movable fan plates 21 return to their free flipping state.

[0030] Furthermore, the surface of the support block 13 near the movable support rod 31 is set in an arc shape, and the arc shape is adapted to the outer wall contour of the movable support rod 31. When the movable support rod 31 swings to be parallel to the slide groove 22, the outer wall of the movable support rod 31 fits against the arc shape, and the support block 13 is locked to the surface of the fixed frame 1 by bolts 132.

[0031] Furthermore, a pad 11 is provided on the side of the fixed frame 1 away from the movable baffle 3. The pad 11 is fixed to the wall by bolts provided on the surface of the fixed frame 1, and the traction mechanism passes through the pad 11 from bottom to top.

[0032] Furthermore, the traction mechanism includes a traction rope 32 and a rotating winding column 12 fixed to the upper end of the pad 11. An arc-shaped block 15 is provided at the upper end of the fixed frame 1. One end of the traction rope 32 is connected to the surface of the movable support rod 31, and the other end passes through the arc-shaped block 15, the pad 11, and the rotating winding column 12 in sequence before winding around the surface of the rotating winding column 12. A wire groove 121 for the traction rope 32 to pass through is provided inside the rotating winding column 12. The wire groove 121 is composed of a winding part and a threading part. The winding part is provided on the surface of the rotating winding column 12, and the threading part is provided inside the rotating winding column 12. The winding part is spirally arranged, and one end of the winding part is provided on the surface of the rotating winding column 12, while the other end extends into the rotating winding column 12 and communicates with the threading part. The threading part extends to the lower end face of the rotating winding column 12. The rotating winding column 12 is threadedly connected to the pad 11, and a rocker arm 122 is provided at the upper end of the rotating winding column 12. When the traction rope 32 passes through the threading part and is wound around the surface of the winding part, the length of the traction rope 32 wound around the surface of the winding part can be increased by rotating the winding column 12.

[0033] The traction mechanism drives the traction rope 32 to wind up by manual rotation, which in turn pulls the movable support rod 31 to swing. Its specific working process is as follows: Threading and Initial Preparation Stage: The construction personnel first fix one end of the traction rope 32 to the surface of the movable support rod 31. The other end of the traction rope 32, as the free end, passes sequentially through the arc-shaped block 15 and the pad 11 at the upper end of the fixed frame 1, and then is introduced into the rotating winding column 12. During threading, the free end of the traction rope 32 is inserted into the threading section inside the rotating winding column 12 from its lower end face, moving upwards along the internal axis of the column until it exits from the starting port of the spiral winding section on the surface of the column. After exiting, the traction rope 32 is wound around the spiral groove of the winding section 1 to 2 times to pre-fit the rope into the spiral groove, completing the threading and pre-fixing.

[0034] Driven winding and tension transmission stage: The construction worker holds the rocker arm 122 at the upper end of the rotating winding column 12 and applies a rotational torque clockwise or counterclockwise in a predetermined direction. Since the rotating winding column 12 and the pad 11 are connected by threads, the rotational action not only drives the column to rotate, but also forces the column to produce axial displacement relative to the pad 11, i.e., moving downward or upward. During the rotation, the spiral grooves on the surface of the winding part generate friction and guidance on the traction rope 32 attached to it, converting the rotational motion of the column into a winding action on the traction rope 32—each rotation causes the traction rope 32 to be arranged and tightened in an orderly manner along the spiral groove, effectively shortening the length of the free section of the traction rope 32 between the movable support rod 31 and the rotating winding column 12.

[0035] Support rod driving and locking stage: As the free section of the traction rope 32 shortens, the traction rope 32 becomes taut and applies a pulling force to the movable support rod 31 in the direction of the fixed frame 1. This pulling force is transmitted through the movable support rod 31 to the movable baffle 3, forcing the movable support rod 31 to swing upwards around its connection point with the movable baffle 3. During this process, the arc-shaped block 15 changes the direction of the pulling force of the traction rope 32, allowing the rope to avoid interference from the edge of the fixed frame 1 and smoothly transmit the horizontal or oblique pulling force to the support rod. The construction personnel continue to shake the rocker arm 122 until the movable support rod 31 swings to a horizontal state parallel to the slide groove 22, at which point the rotation stops. Because the threaded connection has a self-locking characteristic, i.e., the thread helix angle is less than the equivalent friction angle, the rotating winding column 12 will not reverse due to the tension of the traction rope 32 when there is no external driving force, thus maintaining the winding length of the traction rope 32 unchanged and locking the movable support rod 31 in the desired position.

[0036] Unlocking and Reverse Operation Phase: When it is necessary to retract the device or release the support, the construction personnel shake the rocker arm 122 in the opposite direction, the rotating winding column 12 rotates in the opposite direction and returns to its axial position, the winding part gradually releases the winding traction rope 32, the length of the free section of the rope increases, the traction force disappears, and the movable support rod 31 can swing back to its original position under its own weight or manual push.

[0037] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
