Description

Technical Field

[0001] The present application relates to the field of construction protection, and specifically to a protective device for exterior wall construction. Background Art

[0002] In modern engineering construction, when constructing buildings of a certain height, it is necessary to use assembled scaffolding on the periphery of the scaffolding to assist in construction. Scaffolding has many advantages, such as providing auxiliary structural support, protecting workers during high-altitude operations, and facilitating the high-altitude transportation of materials. However, when performing detailed construction of exterior walls, workers need to climb onto the scaffolding and step on the scaffolding steel pipes to perform construction work. This method is extremely dangerous and poses a significant safety risk to workers, as well as other workers located below and on the ground. Therefore, currently, wooden boards are often used to be placed between two scaffolding crossbars, and workers perform construction on the wooden boards. However, the load-bearing capacity of wooden boards is limited, and their strength deteriorates significantly after long-term use. At the same time, they are prone to slipping and displacement during operation, especially in rainy and slippery conditions and when using high-force tools such as electric drills. In addition, due to the different spacing between the scaffolding crossbars, a large number of wooden boards of different lengths need to be prepared to accommodate them. Shorter wooden boards cannot be erected, and longer wooden boards are easily stepped on and cause the edge of the scaffold to be overhanging, resulting in lever reversal.

[0003] For example, the scaffolding with protective function disclosed in publication number CN211286583U includes a frame rod, a transverse connecting rod, a frame plate, and an oblique protective assembly. The frame rods are arranged vertically, and any two of the frame rods are connected and fixed by the transverse connecting rods. The frame plate is laid horizontally and is fastened to the frame rods. The oblique protective assembly includes a protective net and a connecting pin, and the connecting pin is fixed at the corner of the edge of the protective net. The frame rods are provided with a plurality of connecting holes, and the connecting pins cooperate with the connecting holes and are fastened. The above-mentioned protective structure protects the workers in the vertical direction and intercepts dropped objects through the provided protective frame and the oblique protective assembly. However, it cannot be applied to the situation where the spacing between the cross bars of large assembled scaffolding is different and the load-bearing plate needs to be changed for use. It also cannot solve the problem that the load-bearing plate is prone to sliding displacement during operation. Therefore, the present application designs a protective device for exterior wall construction that can lock the scaffolding cross bars to prevent sliding displacement and is adaptable to different widths.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 5 As shown, the utility model provides the following technical solutions: a protective device for exterior wall construction, comprising a plate body 1, an unlocker 2 and a locking mechanism 3 for locking the plate body 1 to the scaffold; the plate body 1 is a telescopic structure, the locking mechanism 3 is slidably connected to the lower part of the plate body 1, the unlocker 2 is slidably connected to the upper part of the plate body 1, the unlocker 2 is slidably connected to the locking mechanism 3, a sliding card block 4 is provided in the locking mechanism 3, the sliding card block 4 is a trapezoidal structure, the locking mechanism 3 drives the sliding card block 4 to clamp the scaffold to fix the plate body 1 on two scaffold cross bars, the plate body 1 locked by the locking mechanism 3 provides protective support for the workers, and the unlocker 2 unlocks the locking mechanism 3 by pressing.

[0024] As another example, Figure 2 and Figure 3 As shown, the plate body 1 includes an inner plate 11 and an outer plate 12. The inner plate 11 and the outer plate 12 have a damped sliding connection inside. The inner plate 11 is slidably connected through a vertical track inside the outer plate 12. A knob 13 for adjusting the sliding damping is provided on the outside of the outer plate 12. A threaded rod 18 is inserted into the side of the knob 13. The threaded rod 18 is threadedly connected to the outer plate 12. The other end of the threaded rod is rotatably connected to a damping plate 19. The damping plate 19 is slidably connected to the inner wall of the outer plate 12 with a limited position, and one side of the damping plate 19 is in contact with the inner plate. When in use, hold the outer plate 12, turn the inner plate 11 downward so that the inner plate 11 slides out from the outer plate 12 to extend the plate body, so that the device can be used between scaffolding cross frames with different spacings. By turning the knob 13, the threaded rod 18 rotates and the damping plate 19 is displaced, which changes the pressure on the inner plate 11, thereby adjusting the damping between the inner plate 11 and the outer plate 12, so that the sliding speed of the inner plate 11 can be controlled.

[0025] See also Figure 1 , an annular groove 14 is formed on the lower part of both the outer plate 12 and the inner plate 11, and a clamping plate 15 is fixedly provided on the side of the annular groove 14. By clamping the clamping plate 15 on one side of the inner plate 11 to the scaffolding crossbar, the annular groove 14 on the inner plate 11 will naturally clamp the scaffolding crossbeam. The clamping plate 15 can play a positioning role. Then, pull the outer plate 12, clamp the clamping plate 15 on the outer plate 12 to the scaffolding crossbeam, and the annular groove 14 will be locked.

[0026] As another example, Figure 1 、 Figure 4 as well as Figure 5 As shown, the locking mechanism 3 includes a cylinder 31, a push spring 32, a spring pin 33, a pedal handle 34 and a locking groove 35; the locking mechanism 3 is provided with two symmetrical groups, the lower end of the cylinder 31 contacts the inclined surface of the sliding block 4, the upper end of the cylinder 31 is plugged into the pedal handle 34, the outer periphery of the two groups of cylinders 31 are respectively slidably connected with the inner plate 11 and the outer plate 12, the spring pin 33 is arranged on the side of the cylinder 31, and the locking groove 35 is opened inside the inner plate 11 and the outer plate 12, one end of the push spring 32 is connected to the sliding block 4, and the other end of the push spring 32 is connected to the inner wall of the inner plate 11 and the outer plate 12. After placing the device on the scaffolding cross frame, the operator steps on the pedal handle 34 downward to make the cylinder 31 slide downward, driving the spring pin 33 to move downward synchronously. The downward-moving cylinder 31 drives the sliding block 4 to move toward the card plate 15, thereby cooperating with the card plate 15 to compress and lock the scaffolding cross frame from two directions. At the same time, the spring pin 33 falls into the locking groove 35 to prevent the push spring 32 from pushing the sliding block 4, so that the cylinder 31 is lifted up. After stepping on the pedal handles 34 on the upper part of the inner plate 11 and the outer plate 12, the device is locked.

[0027] See also Figure 4 The lower part of the inner plate 11 and the outer plate 12 are both provided with a slide groove 16, and the sliding block 4 is slidably connected with the inner plate 11 and the outer plate 12 through the slide groove 16. The lower end of the sliding block 4 is also provided with an arc-shaped portion to fit and clamp the lower part of the scaffolding cross frame to a certain extent, thereby improving the stability of the device and further preventing the device from flipping over.

[0028] See also Figure 4 as well as Figure 5 The unlocker 2 includes a button 21, a pull rod 22, and a slot 23. The slot 23 is provided on the side of the pedal 34. The button 21 is slidably connected to the pedal 34 through the slot 23. The upper end of the pull rod 22 is plugged into the rear end of the button 21, and the lower end of the pull rod 22 is plugged into the spring pin 33. Holes are provided inside the inner and outer panels 11 and 12 for the horizontal displacement of the pull rod 22. When the operation is completed or the device needs to be moved, the button 21 is pressed, causing the pull rod 22 to move horizontally, driving the spring pin 33 out of the locking slot 35. At this time, the spring 32 pushes the sliding block 4 back to its original position, thereby lifting the cylinder 31 and the pedal 34, releasing the device from the locked state. The device can be disassembled by pressing the buttons 21 on the upper ends of the inner and outer panels 11 and 12 respectively.

[0029] See also Figure 5 The inner and outer panels 11 and 12 have receiving holes 17 at their upper ends. In the locked state, the pedal handle 34 is stepped on to move into the receiving hole 17 and does not protrude from the panel surface, thus not affecting the operator. When unlocking is required, the operator simply inserts his hand or a tool into the receiving hole 17 and operates the button 21.

[0030] See also Figure 4 The lower end of the cylinder 31 is set to an inclined surface with the same slope as the inclined surface of the sliding block 4. This makes it easier for the cylinder 31 to drive the sliding block 4, reduces workpiece wear, and increases the service life of the device.

[0031] Working principle: When in use, first turn the inner plate 11 downward so that the inner plate 11 slides out of the outer plate 12. The damping between the inner plate 11 and the outer plate 12 can be adjusted by the knob 13 to control the sliding speed. The card plate 15 at the lower end of the inner plate 11 is clamped to the scaffolding crossbar on the opposite side. The annular card groove 14 naturally clamps the scaffolding crossbar. Then, the annular card groove 14 on the side of the outer plate 12 is clamped to the scaffolding crossbar. By stepping on the pedal 34, the cylinder 31 moves downward, driving the sliding block 4 to move toward the card plate 15, and the scaffolding crossbar is locked. The spring pin 33 bounces into the locking groove 35 to limit the sliding block 4. After the pedal handles 34 at the upper ends of the inner plate 11 and the outer plate 12 are stepped on respectively, the device is locked and installed. When the operation is completed or the device needs to be moved, the button 21 is pressed to drive the spring pin 33 out of the locking groove 35. At this time, the push spring 32 pushes the sliding block 4 back to its original position, and then lifts the cylinder 31 and the pedal handle 34, so that the device is unlocked. After pressing the buttons 21 at the upper ends of the inner plate 11 and the outer plate 12 respectively, the device is disassembled.
