Description

Technical Field

[0001] This invention belongs to the field of scaffolding protection devices, and in particular relates to an internal retaining protection device for external wall scaffolding. Background Technology

[0002] Before commencing work at heights during construction, safety protection facilities should be erected to ensure construction safety. Typically, external scaffolding is required during the main structure and decoration construction of buildings. Currently, in general construction processes, a certain gap is left between the external scaffolding and the concrete beams or shear walls; this gap is called the scaffold inner support, generally 25-30cm. According to regulations, the inner support of the external scaffolding must be sealed off every 10m to prevent falling objects.

[0003] Existing internal protective measures mostly involve covering the space between the scaffolding and the building with pre-cut wooden boards. While this provides some protection, it is not suitable for different construction scenarios and cannot be reused, resulting in waste. On the other hand, existing protective devices that are applicable to different construction scenarios are inconvenient to use and lack stability, thus resulting in poor protective effects. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an internal protective device for external wall scaffolding that is convenient to use, has good stability, and improves the protective effect.

[0005] The aforementioned internal retaining protection device for external wall scaffolding includes a trough, and a support frame that slides left and right with the trough is provided on one side of the trough.

[0006] The support frame has a through groove that connects the front and back. Support rods are horizontally and evenly distributed in the through groove. A support component is provided between the support frame and the groove to make the support frame fit tightly against the wall. A locking component is provided on the groove to prevent the support frame from falling off the wall. A fixing component is provided at the bottom of the groove to connect with the scaffolding.

[0007] Furthermore, the support frame has horizontally opened sliding grooves at both the upper and lower ends, and a slider is provided in the sliding groove to slide left and right with it. Both the sliding groove and the slider have a "T" shaped structure.

[0008] Furthermore, the support assembly includes several evenly distributed first springs, one end of which is fixed to the outer wall of the support frame, and the other end of which is fixed to the inner wall of the groove.

[0009] Furthermore, the locking assembly includes a connecting rod, which is independently installed inside the first spring. Both the groove and the support frame have through holes for the connecting rod to pass through. One end of the connecting rod is located inside the support frame and can rotate freely up and down with it. The other end located outside the groove is fixed with a fixing block. A limiting nut with a threaded engagement is provided on the connecting rod between the fixing block and the groove. The diameter of the through hole is smaller than the diameter of the limiting nut.

[0010] Furthermore, a second spring is provided between the left and right ends of the slider and the slide groove.

[0011] Furthermore, the fixing component includes a horizontally arranged support plate, with a buckle plate hinged to the bottom of the support plate in a clamping state. The buckle plate has an overall arc-shaped structure, and the bottom of the support plate has a groove for interference fit with the steel pipe of the scaffold. When the support plate and the buckle plate are clamped, a circular groove for interference fit with the steel pipe of the scaffold is formed between the support plate and the buckle plate.

[0012] Furthermore, the junction between the top of the trough and the top of the support frame is an inclined surface that is lower on the left and higher on the right.

[0013] Furthermore, the limiting nut consists of two nuts, and the threads of the two nuts are in opposite directions.

[0014] Furthermore, the length of the support plate is less than the length of the connecting block, and the length of the support plate is not less than half the length of the connecting block.

[0015] Furthermore, the bottom of the contact end between the support frame and the wall is rounded.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention facilitates application to construction scenarios with different gaps through the sliding cooperation of the support frame and the groove. Furthermore, the setting of the support components allows the support frame to fit tightly against the wall, thereby increasing the support effect and maintaining stability. The setting of the locking components helps to prevent the support components from being damaged and falling off during use, thus avoiding safety hazards. The setting of the fixing components facilitates connection with scaffolding, thereby covering and protecting the gap between the scaffolding and the wall. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0025] Example 1

[0026] This embodiment describes an internal retaining protection device for external wall scaffolding, such as... Figure 1 and Figure 2 As shown, it includes a groove 1, which is a groove structure without a left side wall and a rear side wall, so that the support frame 2 can be inserted and slide left and right. The groove 1 can also be a groove structure without a left side wall, in which the support frame 2 can be inserted entirely into the groove 1 and slide left and right.

[0027] The tank 1 is provided with a support frame 2 that slides left and right on one side, which makes it easy to adjust the protection length according to different spacing, thereby improving the applicability and the protection effect and avoiding safety hazards due to insufficient protection length.

[0028] The support frame 2 has a through groove that connects the front and back. The support rods 5 are horizontally and evenly distributed in the through groove, which can provide protection while reducing weight and making it easy to carry, and also reduce manufacturing costs.

[0029] A support component is provided between the support frame 2 and the groove 1 to ensure that the support frame 2 is tightly attached to the wall. This ensures that the support frame 2 is always tightly attached to the wall at different gaps, thereby increasing stability, improving support effect and friction to prevent direct detachment.

[0030] The groove 1 is equipped with a locking component to prevent the support frame 2 from falling off the wall, which further increases the support effect between the support frame 2 and the wall, thereby preventing it from falling off and improving the protection effect.

[0031] The bottom of the structure is equipped with a fixing component for connection with the scaffolding, which facilitates connection with the scaffolding and blocks the gap between the scaffolding and the wall, preventing construction workers and building materials from falling directly and improving protection.

[0032] To elaborate further, such as Figure 1 As shown, the support frame 2 has horizontally opened sliding grooves at both the upper and lower ends. A slider 4 is provided in the sliding groove to slide left and right. Both the sliding groove and the slider 4 are "T"-shaped structures, which can increase the smoothness of the support frame 2 sliding left and right in the groove 1 and prevent the support frame 2 and the groove 1 from falling off during the sliding process and affecting safety.

[0033] In practical use, a drawer-type connection can also be adopted, with the side walls of the slot 1 and the support frame 2 connected by guide rails for left and right sliding.

[0034] Example 2

[0035] This embodiment further illustrates the technology, such as Figure 1 As shown, the support assembly includes several evenly distributed first springs 7. One end of the first spring 7 is fixed to the outer wall of the support frame 2, and the other end is fixed to the inner wall of the groove 1, so that the support frame 2 can be squeezed when it slides left and right. Then, the force of the first spring 7 restoring the support frame 2 forms support, which makes it easy to adapt to different gaps, improves the applicability and the support effect, and prevents the support frame 2 from falling directly to the wall.

[0036] The support assembly may also include a plurality of evenly distributed first springs 7. One end of the first spring 7 is fixed to the outer wall of the support frame 2, and the other end is fixed to the inner wall of the groove 1. A stop is provided on the groove 1 or support frame 2 at one end of the first spring 7, and the length of the first spring 7 in the maximum compressed state is equal to or less than the length of the stop, so as to avoid excessive compression of the first spring 7, which may damage the service life or even affect the safety.

[0037] Example 3

[0038] This embodiment further illustrates the technology, such as Figure 1 and Figure 2 As shown, the locking assembly includes a connecting rod 6, which is independently inserted into the first spring 7. This facilitates limiting the contraction path of the first spring 7, thereby increasing stability and improving its service life to a certain extent.

[0039] Both the groove 1 and the support frame 2 are provided with through holes for the connecting rod 6 to pass through. One end of the connecting rod 6 is located inside the support frame 2 and can rotate freely up and down with it. The other end located outside the groove 1 is fixed with a fixing block 8, which is convenient to prevent the movable end of the connecting rod 6 from entering the groove 1 and affecting the left and right sliding of the support frame 2, and to prevent the support frame 2 from sliding too much and falling out of the groove 1.

[0040] The fixed end of the connecting rod 6 is connected to the inner wall of the support frame 2 via a bearing, which facilitates the free rotation of the connecting rod 6.

[0041] The connecting rod 6 between the fixing block 8 and the groove 1 is provided with a limiting nut 9 that is threaded to it, and the diameter of the through hole is smaller than the diameter of the limiting nut 9, so that after the support frame 2 is tightly attached to the wall, it can be further tightened and locked, thereby further increasing the support effect of the support frame 2 and preventing the first spring 7 from affecting the fit between the support frame 2 and the wall when it is damaged, making its support effect more stable.

[0042] To elaborate further, such as Figure 1 As shown, a second spring 3 is provided between the left and right ends of the slider 4 and the slide groove, which can further increase the smoothness of the support frame 2 and the groove 1 when sliding left and right, and can effectively prevent the support frame 2 from getting stuck and unable to slide during the sliding process.

[0043] Example 4

[0044] This embodiment further illustrates the technology, such as Figure 4 and Figure 5 As shown, the horizontally arranged support plate 11 has a buckle plate 12 hinged to its bottom, which is in a clamping state. The buckle plate 12 has an arc-shaped structure. The bottom of the support plate 11 has a groove for interference fit with the steel pipe of the scaffold. When the support plate 11 and the buckle plate 12 are clamped, a circular groove for interference fit with the steel pipe of the scaffold is formed between the support plate 11 and the buckle plate 12. This whole section forms a fixing component for connection with the scaffold, which facilitates connection with the steel pipe of the scaffold, thereby blocking the gap between the scaffold and the wall.

[0045] The fixing component can also use existing fasteners, and a horizontal connecting block 13 is fixed at the top of the fastener. The top of the connecting block 13 is hinged to a connecting block 13 that swings up and down, which facilitates fixing to the steel pipe of the scaffold.

[0046] To elaborate further, such as Figure 4 As shown, the junction of the top of the trough 1 and the top of the support frame 2 is an inclined surface with the left side lower than the right side, which helps to avoid the height difference between the trough 1 and the support frame 2 being too large, affecting the walking of construction workers and preventing construction workers from kicking their feet and falling and getting injured.

[0047] To further explain, the limiting nut 9 consists of two nuts with opposite thread directions (not shown in the figure). This design enhances the fixing effect and prevents the nuts from falling off due to vibration during use, thus maintaining the fixing effect.

[0048] To elaborate further, such as Figure 4As shown, the length of the support plate 11 is less than the length of the connecting block 13, and the length of the support plate 11 is not less than half the length of the connecting block 13. This is to increase the support effect and improve stability while avoiding the connection block 13 being too long and exceeding the balance point, which would increase the burden on the support plate 11 and affect stability.

[0049] In actual use, if the length of the support plate 11 is 5 cm, the length of the connecting block 13 should be 5-10 cm.

[0050] To elaborate further, such as Figure 4 As shown, the bottom of the contact end of the support frame 2 with the wall has rounded corners, which facilitates the downward pressing of the support frame 2 against the wall to complete the fixation. At the same time, it also facilitates the maximum contact surface between the contact end of the support frame 2 and the wall when the support frame 2 is in a horizontal position, thereby increasing stability and friction, and preventing the support frame 2 from continuing to slide downward and causing it to fall off.
