Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a socket-type disc-type scaffold telescopic device. Background Art

[0002] During construction, the formwork support system is a critical component for ensuring construction safety and structural stability. Traditional formwork support systems typically utilize steel tube coupler scaffolding. However, with technological advancements, disc-type scaffolding has gradually become the mainstream choice for construction due to its advantages such as structural stability and ease of assembly and disassembly.

[0003] The disc-type scaffolding is mainly composed of vertical poles, horizontal poles, diagonal poles and other components, and can be quickly assembled and disassembled through the disc-type connection method. However, the horizontal tie rod module of the disc-type scaffolding is usually fixed, and common modules are 0.6 meters, 0.9 meters, 1.2 meters and 1.5 meters. In the actual application of the project, since the position of the beam does not necessarily conform to the secondary module, it is often impossible to fully match. Especially in the plate position, since the formwork is arranged from the beam, when encountering a part that does not conform to the module, it is necessary to use the existing steel pipe fasteners for tensioning, which is not only inefficient, but also has certain safety hazards. Utility Model Content

[0004] In order to flexibly adapt to the different module requirements of horizontal pull rods and improve construction efficiency and safety, the present application provides a socket-type disc-type scaffolding telescopic device.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] A socket-type disc-type scaffold telescopic device includes a pull rod and a fastener. The pull rod includes a connector for connecting to a vertical beam and an adjustable cross bar. The pull rod is provided with two different sizes. Any two of the pull rods are combined into a telescopic pull rod. The telescopic pull rod is composed of two pull rods of the same size or two pull rods of different sizes. The fastener is connected to the overlapping part of the cross bar and is used to fix the two pull rods.

[0007] By adopting the above device, pull rods with horizontal bars of different lengths are set, which can be flexibly combined to adapt to construction requirements of different lengths. In addition, any two pull rods can be combined into a telescopic pull rod type, and the two pull rods are fixed by fasteners to ensure the stability of the telescopic pull rod, thereby improving the stability and safety of the entire scaffolding system. In addition, the rapid assembly and adjustment functions of the pull rods are realized, which effectively reduces the construction time of the scaffolding and improves work efficiency.

[0008] Preferably, in the pull rods of the two different sizes, the lengths of the horizontal bars are different.

[0009] By adopting the above device, the lengths of the horizontal bars are different, which can more accurately match the different size requirements encountered during construction. Construction workers can choose the appropriate size of pull rod according to the actual construction environment and the specific requirements of the formwork support, thereby achieving more precise adjustment and matching.

[0010] Preferably, the length of the pull rod is 500-750 mm.

[0011] By adopting the above device, the length of the pull rod is set to 500-750mm, which covers the non-standard modular sizes commonly found in disc-type scaffolding. This enables the telescopic device to precisely adapt to these specific construction needs, improves the flexibility and adaptability of construction, and allows for more efficient use of materials.

[0012] Preferably, a plurality of adjustment holes are provided on the horizontal bar at intervals, and the width of the adjustment holes is greater than the distance between two adjacent adjustment holes.

[0013] By employing this device, the multiple adjustment holes spaced apart on the horizontal bar allow the fastener to be adjusted between these holes, thereby flexibly adjusting the length of the horizontal bar. Furthermore, because the width of the adjustment holes is greater than the distance between two adjacent adjustment holes, the contact area between the fastener and the horizontal bar is increased, thereby enhancing the stability of the connection and reducing the risk of structural loosening due to an unstable connection.

[0014] Preferably, the fastener includes a plurality of pins, and the plurality of pins are cooperatively inserted into the adjustment holes on the cross bar.

[0015] By adopting the above device, when the telescopic rod is adjusted to a suitable position, the telescopic rod can be quickly fixed by inserting the pin into the adjustment hole, thereby improving the efficiency of scaffolding construction and adjustment, reducing construction difficulty, improving construction convenience, and enhancing the connection stability between the horizontal bars.

[0016] Preferably, when any two of the pull rods are combined into a telescopic pull rod, the length between the two pull rods is 600-1200 mm.

[0017] By adopting the above-mentioned device, the adjustable length range is 600-1200mm, and the length covers a variety of common construction requirements, so that the telescopic device of this application can adapt to a wider range of construction scenarios, improving flexibility and versatility.

[0018] Preferably, the length of the overlapping portion of the horizontal bars in the telescopic pull rod is greater than half the length of any horizontal bar.

[0019] By adopting the above arrangement, the length of the overlapping portion is greater than half the length of the crossbar, ensuring that the connection has sufficient overlapping area to distribute the load, thereby enhancing the strength and stability of the connection.

[0020] Preferably, a locking piece is provided on the connecting head, and the locking piece is used to connect the pull rod and the vertical beam.

[0021] By adopting the above device and providing a locking plate on the connector, the connection between the tie rod and the vertical beam can be ensured to be more secure and stable, reducing the risk of structural instability or safety accidents caused by loose connections. In addition, the locking plate connects the tie rod to the vertical beam, facilitating the installation and removal of the tie rod and improving work efficiency.

[0022] This application has the following beneficial effects:

[0023] 1. In this application, pull rods with horizontal bars of different lengths are provided, which can be flexibly combined to adapt to construction requirements of different lengths. In addition, any two pull rods are combined into a telescopic pull rod type, and the two pull rods are fixed by fasteners to ensure the stability of the telescopic pull rod, thereby improving the stability and safety of the entire scaffolding system. In addition, the rapid assembly and adjustment functions of the pull rods are realized, which effectively reduces the construction time of the scaffolding and improves work efficiency.

[0024] 2. In this application, the multiple adjustment holes spaced apart on the horizontal bar allow the fastener to be adjusted between these holes, thus flexibly adjusting the length of the horizontal bar. Furthermore, because the width of the adjustment holes is greater than the distance between two adjacent adjustment holes, the contact area between the fastener and the horizontal bar is increased, thereby enhancing the stability of the connection and reducing the risk of structural loosening due to an unstable connection.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] Example:

[0032] Socket-type disc-type scaffold expansion device, such as Figure 1-2 As shown, the scaffolding comprises a tie rod 1 and a fastener 2. The tie rods 1 are available in two different sizes. Any two tie rods 1 can be combined to form a telescopic tie rod. This telescopic tie rod can be composed of two tie rods 1 of the same size or two tie rods 1 of different sizes. The fastener 2 is connected to the overlapping portion of the two tie rods 1 to secure them together, simplifying the construction process and improving the safety and reliability of the scaffolding.

[0033] Specifically, such as Figure 1 As shown, the pull rod 1 includes a connector 11 and a horizontal bar 12. The connector 11 is used to connect to the vertical beam 3, and a locking piece 111 is provided on the connector 11. During installation, the locking piece 111 is inserted into the connector 11 and the disc buckle on the vertical beam 3 to complete the connection between the pull rod 1 and the vertical beam 3; during disassembly, the locking piece 111 is pulled out to separate the pull rod 1 from the vertical beam 3. This installation method can ensure that the connection between the pull rod 1 and the vertical beam 3 is more firm and stable, reducing the risk of structural instability or safety accidents caused by loose connections. At the same time, it facilitates the installation and disassembly of the pull rod 1, which helps to improve work efficiency.

[0034] In addition, if Figure 1 As shown, the length of the tie rod 1 can be 500-750mm. In this embodiment, the lengths of the two different sizes of tie rods 1 are 500mm and 750mm respectively. By combining the two lengths of tie rods 1 in different ways, a telescopic tie rod of a desired non-standard modular size can be formed. This allows the telescopic device of the present application to flexibly adapt to different construction requirements, helping to improve construction flexibility and adaptability. In other embodiments, the length of the tie rod 1 can be 600mm, 650mm, 700mm, etc., to meet the needs of different working conditions.

[0035] like Figure 1-2 As shown, a plurality of adjustment holes 121 are spaced apart on the horizontal bar 12. The width of the adjustment hole 121 is greater than the distance between two adjacent adjustment holes 121. In this embodiment, the width of the adjustment hole 121 is set to 30 mm, and the distance between two adjacent adjustment holes 121 is 20 mm. In addition, the fastener 2 includes a plurality of pins 21. During installation, the adjustment holes 121 on the two horizontal bars 12 connected to each other on the telescopic pull rod are aligned with each other, and then the two pins 21 are respectively inserted into the two adjustment holes 121 to fix the two pull rods 1. During disassembly, the pins 21 are pulled out to separate the two pull rods 1, which improves the efficiency of scaffolding construction and adjustment, reduces the difficulty of construction, improves the convenience of construction, and also enhances the connection stability between the horizontal bars 12.

[0036] like Figure 1-3As shown, when any two pull rods 1 are combined into a telescopic pull rod, the adjustable length range of the telescopic pull rod is between 600 mm and 1200 mm, which is selected according to the actual construction scenario. In this embodiment, the telescopic pull rod is divided into two adjustable ranges, namely 600-900 mm and 900-1200 mm. The former telescopic pull rod consists of a 500 mm pull rod 1 and a 750 mm pull rod 1, and the latter telescopic pull rod consists of two 750 mm pull rods 1. In addition, the length of the overlapping part of the horizontal bars 12 in the telescopic pull rod is greater than half the length of any horizontal bar 12, so as to ensure that the connection between the pull rods 1 has sufficient overlapping area to disperse the load, thereby enhancing the strength and stability of the connection, reducing the shaking and deformation of the structure, improving the overall stability of the telescopic pull rod, and reducing the potential safety hazards that may occur during the construction process.

[0037] Working Principle: By docking two tie rods 1 to form an adjustable telescopic tie rod, and securing them with a pin 21, the flexible adjustment requirements of the scaffolding telescopic device of this application are achieved. This application is suitable for various construction scenarios, especially when the position of the vertical beam 3 does not conform to the module during construction. The telescopic device of this application has higher safety, flexibility and reliability.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
