Description

Technical Field

[0001] This application relates to the field of building support structure technology, and in particular to a modular scaffolding component. Background Technology

[0002] To ensure construction safety, scaffolding is usually set up outside the building for workers to stand and work. Scaffolding has many longitudinal and transverse steel structures. Existing scaffolding uses bolts and nuts to fix these longitudinal and transverse structures together. However, the installation and removal of bolts and nuts require tools and are not convenient. Setting up and dismantling scaffolding is quite time-consuming. Utility Model Content

[0003] The purpose of this application is to provide a modular scaffolding component that can effectively improve the efficiency of disassembly and assembly.

[0004] To achieve the above objectives, this application provides a modular scaffolding assembly: including uprights and crossbeams, wherein a bridging sleeve is adapted to be fitted over the uprights, the bridging sleeve is fixed relative to the uprights by an insertable anti-slip member, and the crossbeam is connected to the bridging sleeve by an insertable anti-detachment member; the lower end of one upright is adapted to be fixedly connected to the upper end of another upright by an insertable limiting member, thereby improving the flexibility of longitudinal dimension expansion of the scaffolding.

[0005] As a preferred embodiment, the column is made of hollow steel pipe. The upper end of the column has a top outer pin hole that penetrates the inner and outer walls. The lower end of the column is fixedly connected to a plug end by a retaining ring. The plug end has a bottom inner pin hole that penetrates the side. The plug end of one column is suitable for insertion into the upper end of another column. The limiting member includes a horizontal pin rod, which is suitable for simultaneous insertion into the top outer pin hole and the bottom inner pin hole. One end of the horizontal pin rod is also fixedly connected to a horizontal handle for easy insertion and removal of the horizontal pin rod.

[0006] As a preferred embodiment, the bridging sleeve includes a sleeve fitted over the column, the sleeve having an outer pin hole penetrating the middle of the inner and outer walls, and a middle inner pin hole being formed at the middle height of the column. The anti-slip component includes a longitudinal handle, the end of which has a pin rod suitable for simultaneously engaging with the middle inner pin hole within the middle outer pin hole, ensuring the stability of the bridging sleeve on the outside of the column.

[0007] As a preferred embodiment, the sleeve has an overlap block on its outer side, and each end of the crossbeam has a pair of overlap plates. The overlap block is located between the pairs of overlap plates, and the pairs of overlap plates are connected to the overlap block through the anti-detachment component to ensure the stable configuration of the crossbeam.

[0008] As a preferred embodiment, the overlapping block has an inner longitudinal pin hole that runs through the upper and lower surfaces, and the paired overlapping plates have aligned outer longitudinal pin holes. The anti-detachment component includes a longitudinal pin rod, which is suitable for simultaneous insertion into the outer longitudinal pin hole and the inner longitudinal pin hole. The upper end of the longitudinal pin rod is also fixedly connected to a slanted handle for easy insertion and removal of the longitudinal pin rod.

[0009] As a preferred embodiment, a base is also inserted into the lower end of the bottom column, and the base is also fixed relative to the column by a limiting member, thereby ensuring the stability of the column configuration.

[0010] As a preferred embodiment, the base includes a plug sleeve adapted to be fitted over the plug end. The plug sleeve has a bottom outer pin hole that penetrates the inner and outer walls. The horizontal pin is adapted to simultaneously engage with the bottom outer pin hole and the bottom inner pin hole, thereby limiting the position and angle of the column relative to the base.

[0011] As a preferred embodiment, the lower end of the plug sleeve has a retaining ring, and the retaining ring has a connecting hole on the part outside the plug sleeve, which is suitable for bolts and other connecting parts to pass through to fix the base to a solid bottom surface.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: (1) By designing limiting components to limit the insertion between columns, by designing anti-slip components to limit the insertion between the bridge sleeve and the column, and by designing anti-detachment components to limit the insertion between the beam and the bridge sleeve, the scaffolding can be dismantled and assembled quickly without the need for additional tools, thus improving the efficiency of scaffolding configuration and dismantling. (2) By designing modular assembly units such as columns, bridging sleeves, limiting parts, anti-slip parts, crossbeams, anti-detachment parts and bases, the size expansion of the scaffolding is more flexible. The limiting parts, anti-slip parts and anti-detachment parts can use friction and their own weight to maintain the stability of the connection. The erected scaffolding can maintain good structural stability. Attached Figure Description

[0024] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-10 The modular scaffolding assembly shown includes uprights 1 and beams 5. Uprights 1 are made of hollow steel pipes and are typically installed vertically, while beams 5 are typically installed horizontally. A bridging sleeve 2 can be fitted over the uprights 1. The bridging sleeve 2 is fixed relative to the uprights 1 by inserting anti-slip parts 4. Specifically, the bridging sleeve 2 includes a sleeve 201 fitted over the uprights 1. Before being fixed, the sleeve 201 can slide along the outer side of the uprights 1. The sleeve 201 has two sets of external pin holes 202 penetrating the middle of the inner and outer walls, for a total of four holes, with two holes in each set. The column 1 is aligned with the central inner pin hole 104 at its middle height. The number of central inner pin holes 104 is the same as the number of central outer pin holes 202, and they can be aligned. The anti-slip component 4 includes a vertical handle 401. The end of the vertical handle 401 has a pin 402. Both ends of the vertical handle 401 have pins 402. The two pins 402 are parallel to each other and perpendicular to the vertical handle 401. Each pin 402 can be simultaneously inserted into the central inner pin hole 104 in the central outer pin hole 202, thereby restricting the bridge sleeve 2 to the middle part outside the column 1.

[0029] The crossbeam 5 is connected to the bridging sleeve 2 via an insertable anti-detachment component 6. Specifically, the sleeve 201 has overlapping blocks 203 on its outer side. Each sleeve 201 has four, six, or eight overlapping blocks 203 on its outer side; typically, four are chosen. These overlapping blocks 203 are equidistantly arranged around the axis of the sleeve 201. Each end of the crossbeam 5 has a pair of overlapping plates 501, which are parallel to each other. The overlapping blocks 203 can be located between the pairs of overlapping plates 501. The pairs of overlapping plates 501 are connected to the overlapping blocks 203 via the anti-detachment component 6. To achieve the anti-detachment component 6... For rapid configuration, a matching interlocking structure needs to be designed. An inner longitudinal pin hole 204 penetrating the upper and lower surfaces will be opened in the overlapping block 203, and an outer longitudinal pin hole 502 will be opened in the paired overlapping plate 501. The outer longitudinal pin hole 502 can be aligned with the inner longitudinal pin hole 204. The specific structure of the anti-detachment component 6 includes a longitudinal pin rod 601, which is used to simultaneously insert into two outer longitudinal pin holes 502 and one inner longitudinal pin hole 204. The upper end of the longitudinal pin rod 601 is also fixedly connected to a slanted handle 602, which makes it easy to lift upwards and pull the longitudinal pin rod 601 out of the inner longitudinal pin hole 204 and the outer longitudinal pin hole 502.

[0030] The lower end of one column 1 can be fixedly connected to the upper end of another column 1 through a plug-in limiting member 3. Specifically, the upper end of column 1 has a top outer pin hole 103 that penetrates the inner and outer walls, and the lower end of column 1 is fixedly connected to a plug end 102 through a retaining ring 101. The plug end 102 has a bottom inner pin hole 105 that penetrates the side. The plug end 102 of one column 1 is suitable for plugging into the upper end of another column 1. The limiting member 3 includes a horizontal pin 301, which can be plugged into both the top outer pin hole 103 and the bottom inner pin hole 105 at the same time, thereby constraining the lower end of the upper column 1 together. One end of the horizontal pin 301 is also fixedly connected to a horizontal handle 302, which facilitates the application of insertion and extraction forces to the horizontal pin 301.

[0031] The lower end of the bottom column 1 is also connected to a base 7. The base 7 also needs to be fixed relative to the column 1 by the limiting member 3. The base 7 includes a plug sleeve 701, which is used to fit over the plug end 102. The plug sleeve 701 has a bottom outer pin hole 702 that passes through the inner and outer walls, which is suitable for aligning with the bottom inner pin hole 105. The horizontal pin 301 is inserted into both the bottom outer pin hole 702 and the bottom inner pin hole 105 at the same time. The lower end of the plug sleeve 701 has a coaxial fixing ring 703. The part of the fixing ring 703 outside the plug sleeve 701 has a connecting hole 704, through which bolts or rivets and other connecting parts are passed to fix the base 7 to the solid ground, thereby ensuring the stability of the entire scaffold.

[0032] Working principle: Bolts or rivets are pre-embedded in suitable locations on the cement ground. During assembly, the required base 7 is first matched with the pre-embedded bolts, and all bases 7 are fixed to the cement ground with nuts. Then, the column 1 is taken and its insertion end 102 is inserted into the insertion sleeve 701, and the insertion is constrained by the limiting member 3. The limiting member 3 will penetrate the insertion sleeve 701 and use friction to keep it stable within the bottom inner pin hole 105 and the bottom outer pin hole 702. Then, a bridging sleeve 2 is put on each column 1 and constrained by the anti-slip member 4. The pin 402 passes through the sleeve 201 and is kept stable in the middle inner pin hole 104 and the middle outer pin hole 202 by friction. Then, a crossbeam 5 is erected between adjacent bridging sleeves 2, so that the overlapping plates 501 at both ends of the crossbeam 5 are aligned with the overlapping blocks 203 on the opposite side of the bridging sleeve 2, and the anti-detachment parts 6 are used for insertion and restraint. The longitudinal pin 601 passes through the two overlapping plates 501 and is kept stable in the inner longitudinal pin hole 204 and the outer longitudinal pin hole 502 by its own weight. When all the crossbeams 5 are in place, a transverse structure is formed.

[0033] Continue to take column 1 and insert its lower end into the upper end of the nearly fixed column 1, and use the limiting member 3 for restraint. The horizontal pin 301 will pass through column 1 and use friction to keep it stable in the bottom inner pin hole 105 and the top outer pin hole 103. Then install in the same way, use the bridging sleeve 2 to configure the horizontal beam 5, and then continue to configure the next layer of horizontal structure until a complete scaffold is formed. The completed scaffold has sufficient stability. Because all the components of this scaffolding are connected by plug-in joints, they can be quickly disassembled, sorted, organized, and recycled during dismantling. Therefore, this modular scaffolding component is not only highly efficient to assemble, but also highly efficient to dismantle.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
