Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building construction, and particularly relates to a positioning device for a vertical pipe of a cantilevered scaffolding. Background Art
[0002] At the present stage, the cantilevered frame of multi-story high-rise buildings is still the preferred method for structural construction and exterior decoration work. During the construction process, it involves the installation and positioning of the steel pipes of the cantilevered scaffolding on the cantilevered steel beams (I-beams). Vertical steel bars are welded on the cantilevered steel beams through through slots, and then the lower end of the vertical pipe (steel pipe) is sleeved on the vertical steel bars, and the transverse connecting pipes are connected to multiple vertical pipes through fasteners to form a cantilevered scaffolding.
[0003] The erection of the existing cantilevered scaffolding requires welding positioning steel bars, and during the later disassembly of the positioning steel bars, operations such as cutting are also time-consuming and laborious.
[0004] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention
[0005] To overcome the defects existing in the prior art, the present invention provides a positioning device for a vertical pipe of a cantilevered scaffolding to solve the problem of the cumbersome installation and disassembly of the existing cantilevered scaffolding.
[0006] To achieve the above object, a positioning device for a vertical pipe of a cantilevered scaffolding is provided, including:
[0007] A support member for resting on the upper flange plate of the cantilevered steel beam, with both ends of the support member upturned to form upturned plate segments;
[0008] An insertion rod vertically provided on one upturned plate segment;
[0009] Limiting flanges, with the opposite sides of the other upturned plate segment turned down respectively to form the limiting flanges, and a clamping space for clamping the upper flange plate is formed between the two limiting flanges;
[0010] An anti-slip flange for preventing the upper flange plate from slipping off, with the anti-slip flange formed by the opposite sides of the two limiting flanges extending towards each other, and the distance between the anti-slip flange and the other upturned plate segment being greater than the thickness of the upper flange plate. After the upper flange plate penetrates through the clamping space, the vertical pipe of the cantilevered scaffolding is sleeved on the insertion rod, and one upturned plate segment is turned downwards under the downward pressure of the vertical pipe to cause the other upturned plate segment to turn upwards. After the other upturned plate segment turns upwards, the anti-slip flange presses against the bottom of the upper flange plate to lock the upper flange plate.
[0011] Further, a first anti-slip cushion layer is laid at the bottom of the support member.
[0012] Further, a second anti-slip cushion layer is laid on the anti-slip flange.
[0013] Further, anti-slip lines are formed at the bottom of the support member.
[0014] Further, the distance from the insertion rod to the support member is greater than the distance from the end of the anti-slip flange away from the support member to the support member.
[0015] Further, lower hanging plates are rotatably mounted on opposite sides of the one seesaw section. A locking block is formed on the inner side of the lower hanging plate. The distance between the two locking blocks is less than the width of the upper flange plate. An extrusion slope is formed at the bottom of the locking block. The extrusion slope is arranged obliquely upward towards the inner side of the upper flange plate. After the one seesaw section is turned downward, the upper flange plate outwardly pushes against the extrusion slope, and the lower hanging plate turns outward and upward to enable the upper flange plate to extend above the locking block. After the upper flange plate extends above the locking block, the lower hanging plate turns inward and downward, so that the locking block abuts against the bottom of the upper flange plate to lock the upper flange plate.
[0016] Further, the lower hanging plate is rotatably connected to the side of the one seesaw section through a hinge shaft.
[0017] Further, the locking block is arranged at the bottom of the lower hanging plate.
[0018] The beneficial effect of the present invention is that the positioning device for the vertical pipe of the suspended scaffold of the present invention is attached to the upper flange plate of the suspended steel beam through the clamping space and the anti-slip flange. After the frame body is installed on the insertion rod, the weight of the frame body is used to press down the seesaw section to lock the positioning device for the vertical pipe of the suspended scaffold of the present invention on the suspended steel beam automatically, realizing the efficient and convenient installation and disassembly of the positioning device for the vertical pipe of the suspended scaffold of the present invention, and improving the erection efficiency of the suspended scaffold. On the other hand, the suspended steel beam after disassembly does not need to be cut, and the suspended steel beam and the positioning device for the vertical pipe of the suspended scaffold of the present invention can be reused, improving the turnover efficiency and reducing the engineering construction cost.

[0026] The following further elaborates the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. Additionally, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings.
[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will elaborate the present application in detail with reference to the drawings and embodiments.
[0028] Refer to Figures 1 to 6 As shown, the present invention provides a positioning device for the vertical pipe of a cantilever scaffold, including: a support member 1, a plug rod 2, a limiting flange 3, and an anti - detachment flange 4.
[0029] The positioning device for the vertical pipe of the cantilever scaffold of the present invention is used for the cantilever scaffold. The cantilever scaffold includes a cantilever steel beam and a scaffold body. The scaffold body is installed on the cantilever steel beam through the positioning device for the vertical pipe of the cantilever scaffold of the present invention. The cantilever steel beam is an I - shaped steel beam. Specifically, the cantilever steel beam 7 includes an upper flange plate 71, a lower flange plate, and a web 72. The web is connected between the upper flange plate and the lower flange plate.
[0030] Both ends of the support member 1 are upturned to form upturned plate segments 11. In this embodiment, the length of the support member is relatively small. With the support member as the fulcrum, when an upward or downward pressure is applied to one upturned plate segment, the other upturned plate segment will turn downward or upward in the opposite direction with the support member as the fulcrum. The support member and the two upturned plate segments are integrally formed to form a lever structure.
[0031] In use, the support member 1 is used to rest on the upper flange plate 71 of the cantilever steel beam 7.
[0032] The plug rod 2 is vertically arranged on one upturned plate segment 11. In use, the lower end of the vertical pipe of the scaffold body of the cantilever scaffold is sleeved on the plug rod.
[0033] On opposite sides of the other rocker segment 11, downward flips are respectively formed to form limiting flanges 3. A clamping space is formed between the two limiting flanges 3. The clamping space is used to clamp the upper flange plate 71.
[0034] In this embodiment, the distance between the limiting flanges on opposite sides of the other rocker segment is adapted to the width of the upper flange plate. A clamping through groove is formed by enclosing between the two limiting flanges and the bottom surface of the other rocker segment, and the upper flange plate is slidably disposed in the clamping through groove.
[0035] Anti - detachment flanges 4 are formed by extending oppositely on the opposite sides of the two limiting flanges 3. The distance from the anti - detachment flanges 4 to the other rocker segment 11 is greater than the thickness of the upper flange plate 71. The anti - detachment flanges 4 are used to prevent the upper flange plate 71 from slipping off. Specifically, the anti - detachment flanges are used to prevent the upper flange plate from slipping off from the notch of the clamping through groove.
[0036] During the actual erection process of the cantilevered scaffolding, first, the cantilevered steel beam is installed on the outer facade of the building structure. Align the clamping space of the positioning device for the vertical pipe of the cantilevered scaffolding of the present invention with the end of the upper flange plate of the cantilevered steel beam, and movably insert the upper flange plate through the clamping space. After the insertion rods of the positioning devices for the vertical pipes of the cantilevered scaffolding of the present invention are respectively installed on multiple cantilevered steel beams and moved to the designed positions, the lower end of the vertical pipe of the framework is sleeved on the insertion rod, such that one rocker segment supports on the vertical pipe. After the vertical pipe is sleeved on the insertion rod, cross bars are erected on multiple vertical pipes to form the framework of the cantilevered scaffolding. At this time, the weight of the framework is dispersed and pressed against one rocker segment of multiple positioning devices for the vertical pipes of the cantilevered scaffolding of the present invention, such that one rocker segment flips downward with the support member as the fulcrum. Correspondingly, the other rocker segment flips upward with the support member as the fulcrum. After the other rocker segment flips upward with the support member as the fulcrum, the anti - detachment flanges on the other rocker segment press against the bottom of the upper flange plate to prevent the upper flange plate from slipping off from the clamping space (i.e., the notch of the clamping through groove), thereby forming the positioning device for the vertical pipe of the cantilevered scaffolding of the present invention to be self - locked on the upper flange plate of the cantilevered steel beam, effectively locking the framework on multiple cantilevered steel beams.
[0037] After the framework is demolished, after the downward pressure on one rocker segment disappears, the anti - detachment flanges release the pressing and locking on the upper flange plate. Correspondingly, the installation and disassembly of the positioning device for the vertical pipe of the cantilevered scaffolding of the present invention are convenient and efficient.
[0038] The positioning device for the vertical pipe of the cantilever scaffold of the present invention is attached to the upper flange plate of the cantilever steel beam through the clamping space and the anti - detachment flange. After the scaffold is installed on the insertion rod, the weight of the scaffold presses down the rocker section to lock the positioning device for the vertical pipe of the cantilever scaffold of the present invention onto the cantilever steel beam, achieving efficient and convenient installation and disassembly of the positioning device for the vertical pipe of the cantilever scaffold of the present invention, and improving the erection efficiency of the cantilever scaffold. On the other hand, the cantilever steel beam after disassembly does not need to be cut, and the cantilever steel beam and the positioning device for the vertical pipe of the cantilever scaffold of the present invention can be reused, improving the turnover efficiency and reducing the engineering construction cost.
[0039] After the upper flange plate 71 passes through the clamping space, the vertical pipe of the cantilever scaffold is sleeved on the insertion rod 2. One rocker section 11 flips downward after being pressed by the vertical pipe, causing the other rocker section 11 to flip upward. After the other rocker section 11 flips upward, the anti - detachment flange 4 presses against the bottom of the upper flange plate 71 to lock the upper flange plate 71.
[0040] As a preferred embodiment, a first anti - slip cushion layer is laid at the bottom of the support member 1. Preferably, a second anti - slip cushion layer is laid on the anti - detachment flange 4. Further, the first anti - slip cushion layer and the second anti - slip cushion layer are rubber anti - slip cushion layers.
[0041] In some embodiments, anti - slip cushion layers are respectively laid at the bottoms of the support member and the rocker section
[0042] In some other embodiments, anti - slip patterns are formed at the bottom of the support member 1.
[0043] Continue to refer to Figure 2 As shown, the distance L1 from the insertion rod 2 to the support member 1 is greater than the distance L2 from the end of the anti - detachment flange 4 far from the support member 1 to the support member 1.
[0044] As a preferred embodiment, refer to Figure 5 and Figure 6 As shown, lower hanging plates 5 are rotatably installed on opposite sides of one rocker section 11. Lock blocks 6 are formed on the inner sides of the lower hanging plates 5. The distance between the two lock blocks 6 is less than the width of the upper flange plate 71. An extrusion slope 60 is formed at the bottom of the lock block 6. The extrusion slope 60 is inclined upward and inward towards the upper flange plate 71. After one rocker section 11 flips downward, the upper flange plate 71 pushes against the extrusion slope 60 outward. The lower hanging plates 5 flip outward and upward, causing the upper flange plate 71 to extend above the lock blocks 6. After the upper flange plate 71 extends above the lock blocks 6, the lower hanging plates 5 flip inward and downward, so that the lock blocks 6 abut against the bottom of the upper flange plate 71 to lock the upper flange plate 71.
[0045] Continue to refer to Figure 6As shown, the lower hanging plate 5 is pivotally connected to the side of a rocker segment 11 through a hinge shaft 51. A locking block 6 is provided at the bottom of the lower hanging plate 5. The locking block is wedge-shaped. The top of the locking block is a flat surface, and the bottom of the locking block is a ramp surface.
[0046] The above description is only the preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) having similar functions disclosed in the present application.
