Description

Technical Field

[0001] This application relates to the technical field of scaffolding structures, and in particular to anti-sinking trusses. Background Technology

[0002] When constructing modular scaffolding, due to the need for access to building entrances, semi-basement light wells, and vehicle access, it's often impossible to ensure that every scaffolding pole is firmly on the ground. Some sections of the scaffolding may be suspended in the air to allow space for vehicle access.

[0003] Disc-lock scaffolding uses socket-type connections. Currently, diagonal braces are often used to set up reverse supports to ensure that the uprights that are not on the ground do not fall. However, because the connection points of socket-type disc-lock scaffolding will have a certain degree of deformation and movement, the uprights may sag, resulting in poor overall scaffolding performance and even safety hazards.

[0004] Regarding the aforementioned technologies, it has been found that existing scaffolding often has overhead pipe structures at the entrance and exit points. In actual use, the suspended round pipes connected by disc buckles are prone to sinking due to external vibrations or long-term stress. When the sinking accumulates to a certain extent, it will seriously affect the overall stability and safety of the scaffolding. Utility Model Content

[0005] To reduce the sinking of suspended scaffolding pipes, this application provides an anti-sinking truss.

[0006] The anti-sinking truss provided in this application adopts the following technical solution:

[0007] The anti-sinking truss includes a main truss, which consists of two parallel square tubes connected at the middle by a support base. The support base is sleeved on the square tube and fixedly connected to it. A tilting frame assembly is installed at both ends of the square tube. One end of the tilting frame assembly is fixedly connected to the square tube, and the other end of the tilting frame assembly is equipped with a length adjustment frame. The length adjustment frame is rotatably connected to the tilting frame assembly, and the lower end of the length adjustment frame is supported on the ground. A reinforcing bracket is also installed between the length adjustment frame and the square tube.

[0008] By adopting the above technical solution, the main truss consists of two parallel square tubes. These square tubes possess high strength and stability, enabling them to withstand significant weight. The two square tubes are connected by support bases, further enhancing the overall structural strength of the main truss and preventing deformation during load-bearing, effectively preventing truss subsidence. After the main truss is assembled, tilting frame assemblies can be fixedly installed at both ends. These tilting frame assemblies are then used to connect length adjustment frames. In use, the length adjustment frames at both ends provide stable support for the main truss, ensuring that the main truss can support the suspended vertical pipes of the scaffolding through the support base sleeves. This multi-structure support system effectively prevents subsidence.

[0009] Optionally, the support base includes a double-shell base and a suspended insertion tube, wherein the suspended insertion tube is vertically installed at the center of the upper end face of the double-shell base and is fixedly connected to the double-shell base.

[0010] By adopting the above technical solution, and by designing the support base as a structure that combines a double-shell base and a suspended insertion tube, it is ensured that the double-shell base can be fitted onto the two square tubes during use, thus ensuring stable support for the suspended insertion tube on the upper end. Moreover, by placing the suspended insertion tube at the center of the upper end of the double-shell base, the ductwork is more even, making it more convenient for the two square tubes to be stably supported.

[0011] Optionally, the double-shell base includes a shell portion and a middle base plate for suspending the insertion tube. The shell portion is symmetrically installed at both ends of the middle base plate and is fixedly connected to the middle base plate. The shell portion is sleeved and fixed in the middle of the square tube.

[0012] By adopting the above technical solution, the shell portion of the double-shell base is fitted and fixed in the middle of the square tube, increasing the support points of the square tube and distributing the pressure borne by the square tube. The suspended insertion tube not only serves as a connection point for the suspended vertical pipes of the scaffolding, but also enhances the stability of the support base to a certain extent.

[0013] Optionally, the suspended insertion tube includes a riser section and a reinforcing plate. The riser section is fixedly installed at the center of the upper surface of the middle seat plate, and the reinforcing plate is fixedly installed between the riser section and the casing section.

[0014] By adopting the above technical solution, the combined design of the sleeve and the telescopic inner tube allows the length of the length adjustment frame to be adjusted according to the flatness of the ground and actual support requirements. Locking the telescopic inner tube with connecting bolts ensures that the length adjustment frame maintains a stable length after adjustment, providing reliable support for the truss and preventing truss subsidence due to uneven ground. The reinforcing plate further improves the connection strength between the suspended insert and the double-shell base, enabling the support base to better perform its supporting function and preventing the main truss from subsiding.

[0015] Optionally, the flipping frame assembly includes a plug-in shell and a flipping seat for mounting the length adjustment frame. One end of the plug-in shell is sleeved and fixed on the square tube, and the flipping seat is installed at the other end of the plug-in shell, and the flipping seat is rotatably connected to the plug-in shell.

[0016] By adopting the above technical solution, the tilting seat and the plug-in shell are rotatably connected, allowing the length adjustment frame to be angled according to actual needs, adapting to different ground conditions and usage scenarios. This adjustable structural design increases the flexibility and applicability of the truss, ensuring that the length adjustment frame can be stably supported on the ground, thereby effectively preventing the truss from sinking. By setting the tilting frame as a structure in which the plug-in shell and the tilting seat cooperate, the plug-in shell can be fitted onto both ends of the square tube during use and connected and fixed by bolts, while the tilting seat ensures that the length adjustment frame can be stably fitted and fixedly connected.

[0017] Optionally, the plug-in shell includes a vertical plate, an end shell sleeve, and an outer ear plate for rotating installation of the flip seat. The end shell sleeve and the outer ear plate are respectively fixed on both sides of the vertical plate, and the vertical plate, the end shell sleeve, and the outer ear plate are integrally formed.

[0018] By adopting the above technical solution, the plug-in shell is designed with a structure in which the base plate, end shell sleeve and outer ear plate cooperate, ensuring that it can be fixedly connected to the square tube through the end shell sleeve during use, and the setting of the outer ear plate ensures that the length adjustment frame can be stably connected and used.

[0019] Optionally, the length adjustment frame includes a sleeve and a telescopic inner tube. The head of the sleeve is fitted and fixed on the flip seat, and the telescopic inner tube is slidably installed on the lower end of the sleeve. The sleeve is also equipped with connecting bolts that lock together with the telescopic inner tube.

[0020] By adopting the above technical solution, and by designing the length adjustment frame as a structure in which a sleeve and a telescopic inner tube cooperate, it is ensured that the telescopic inner tube can be slidably adjusted to adjust the overall length of the length adjustment frame during use. After the length is adjusted, it can be fixedly connected by drilling holes and inserting bolts.

[0021] Optionally, the reinforcing bracket includes a mounting base and an auxiliary inclined frame. The mounting base is fixedly mounted on the main truss, the head of the auxiliary inclined frame is rotatably connected to the mounting base, and the lower end of the auxiliary inclined frame is fixedly connected to the sleeve by bolts.

[0022] By adopting the above technical solution, the reinforced bracket installed between the length adjusting frame and the square tube can form a supporting triangular structure, ensuring greater overall stability. Furthermore, by designing the reinforced bracket as a structure that combines a mounting base and an auxiliary diagonal frame, the auxiliary diagonal frame increases the connection strength and stability between the length adjusting frame and the main truss. It can transfer some of the pressure borne by the length adjusting frame to the main truss, further dispersing the pressure and improving the overall truss's resistance to subsidence.

[0023] In summary, this application includes at least one of the following beneficial technical effects: By increasing the support points of the main truss through the support base, the adjustability of the tilting frame assembly and the length adjustment frame, and the enhanced auxiliary support function of the support frame, this application effectively improves the overall stability of the truss and prevents it from sinking during use. The adjustable length of the length adjustment frame and the adjustable angle of the tilting frame assembly allow the truss to adapt to different ground conditions and usage scenarios, improving its applicability. In actual use, it can flexibly provide stable support for the scaffolding, ensuring the overall stability and safety of the scaffolding. Attached Figure Description

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses an anti-sinking truss in its embodiments. (Refer to...) Figure 1 , Figure 2 and Figure 3 As shown, the anti-sinking truss includes a main truss 1, which consists of two parallel square tubes connected at their midpoints by a support 2. The support 2 is fitted onto the square tubes and fixedly connected to them. Tilting frame assemblies 3 are installed at both ends of the square tubes. One end of each tilting frame assembly 3 is fixedly connected to the square tube, and the other end is equipped with a length adjustment frame 4. The length adjustment frame 4 is rotatably connected to the tilting frame assembly 3, and its lower end is supported on the ground. A reinforcing bracket 5 is also installed between the length adjustment frame 4 and the square tubes. The main truss 1, composed of two parallel square tubes, possesses high strength and stability, enabling it to withstand significant weight. The connection of the two square tubes via the support 2 further enhances the overall structural strength of the main truss 1, making it less prone to deformation during load-bearing and effectively preventing truss sinking. After the main truss 1 is assembled, tilting frame assemblies 3 can be fixedly installed at both ends. The length adjustment frames 4 are then connected via the tilting frame assemblies 3. This allows the length adjustment frames 4 at both ends to provide stable support for the main truss 1 during use. The main truss 1 can also support the suspended vertical pipes of the scaffolding using support seats 2 sets. Multiple structural supports work together to prevent sinking. The main truss 1 uses two parallel square tubes, preferably made of high-strength carbon steel, such as Q345 carbon steel, which has good strength and toughness and can withstand large loads. The specifications of the square tubes can be selected according to actual usage requirements.

[0033] Reference Figure 2 and Figure 3As shown, the support base 2 includes a double-shell base 21 and a suspended insertion tube 22. The suspended insertion tube 22 is vertically installed at the center of the upper surface of the double-shell base 21 and is fixedly connected to the double-shell base 21. By designing the support base 2 into a structure where the double-shell base 21 and the suspended insertion tube 22 cooperate, it is ensured that the double-shell base 21 can be fitted onto two square tubes during use, thus ensuring stable support for the suspended insertion tube 22 on the upper surface. Furthermore, placing the suspended insertion tube 22 at the center of the upper surface of the double-shell base 21 ensures more even distribution and facilitates stable support for the two square tubes. Both the double-shell base 21 and the suspended insertion tube 22 of the support base 2 are made of carbon steel, matching the material of the square tubes to ensure the strength and stability of the connection. The double-shell base 21 includes a casing portion 211 and a middle base plate 212 for mounting the suspended insertion tube 22. The casing portion 211 is symmetrically installed at both ends of the middle base plate 212 and is fixedly connected to the middle base plate 212. The casing portion 211 is fitted and fixed in the middle of the square tube. The casing portion 211 of the double-shell base 21, fitted and fixed in the middle of the square tube, increases the support points of the square tube and distributes the pressure borne by the square tube. The suspended insertion tube 22 can not only serve as a connection point for the suspended upright of the scaffold, but also enhance the stability of the support base 2 to a certain extent. The suspended insertion tube 22 includes an upright portion 221 and a reinforcing plate 222. The upright portion 221 is fixedly installed at the center of the upper end face of the middle base plate 212, and the reinforcing plate 222 is fixedly installed between the upright portion 221 and the casing portion 211. The combined design of the sleeve 41 and the telescopic inner tube 42 allows the length of the length adjustment frame 4 to be adjusted according to the flatness of the ground and the actual support requirements. By locking the telescopic inner tube 42 with connecting bolts, the length adjustment frame 4 can maintain a stable length after adjustment, providing reliable support for the truss and preventing the truss from sinking due to uneven ground. The reinforcing plate 222 further improves the connection strength between the suspended insertion tube 22 and the double shell base 21, enabling the support base 2 to better perform its supporting function and prevent the main truss 1 from sinking.

[0034] Reference Figure 4As shown, the tilting frame assembly 3 includes a plug-in shell 31 and a tilting seat 32 for mounting the length adjustment frame 4. One end of the plug-in shell 31 is fitted and fixed onto the square tube, and the tilting seat 32 is mounted on the other end of the plug-in shell 31, with the tilting seat 32 rotatably connected to the plug-in shell 31. This rotatable connection allows the length adjustment frame 4 to be adjusted in angle according to actual needs, adapting to different ground conditions and usage scenarios. This adjustable structural design increases the flexibility and applicability of the truss, ensuring that the length adjustment frame 4 can be stably supported on the ground, thus effectively preventing truss sagging. By setting the tilting frame in a structure where the plug-in shell 31 and the tilting seat 32 cooperate, the plug-in shell 31 can be fitted onto both ends of the square tube and fixed with bolts during use, while the tilting seat 32 ensures that the length adjustment frame 4 can be stably fitted and fixed. The plug-in shell 31 and the tilting seat 32 of the tilting frame assembly 3 are made of cast steel, possessing high strength and wear resistance. The plug-in housing 31 includes a vertical plate 311, an end sleeve 312, and an outer ear plate 313 for the rotating mounting base 32. The end sleeve 312 and the outer ear plate 313 are respectively fixed on both sides of the vertical plate 311, and the vertical plate 311, the end sleeve 312, and the outer ear plate 313 are integrally formed. By designing the plug-in housing 31 with a structure in which the vertical plate 311, the end sleeve 312, and the outer ear plate 313 cooperate, it is ensured that the end sleeve 312 can be used to fix and connect to the square tube, while the outer ear plate 313 ensures that the length adjustment frame 4 can be stably connected and used.

[0035] Reference Figure 6 As shown, the length adjusting frame 4 includes a sleeve 41 and a telescopic inner tube 42. The head of the sleeve 41 is fitted and fixed on the flip base 32, and the telescopic inner tube 42 is slidably installed on the lower end of the sleeve 41. A connecting bolt that locks with the telescopic inner tube 42 is also installed on the sleeve 41. By designing the length adjusting frame 4 with a structure in which the sleeve 41 and the telescopic inner tube 42 cooperate, it is ensured that the overall length of the frame 4 can be adjusted by sliding the telescopic inner tube 42 during use. After the length is adjusted, it can be fixedly connected by inserting bolts through drilling holes. The sleeve 41 and the telescopic inner tube 42 of the length adjusting frame 4 are made of seamless steel pipes, which have good sealing performance and strength.

[0036] Reference Figure 5As shown, the reinforcing bracket 5 includes a mounting base 51 and an auxiliary diagonal bracket 52. The mounting base 51 is fixedly mounted on the main truss 1. The head of the auxiliary diagonal bracket 52 is rotatably connected to the mounting base 51, and the lower end of the auxiliary diagonal bracket 52 is fixedly connected to the sleeve 41 by bolts. The reinforcing bracket 5, installed between the length adjusting frame 4 and the square tube, forms a supporting triangular structure, ensuring greater overall stability. Furthermore, by designing the reinforcing bracket 5 as a structure where the mounting base 51 and the auxiliary diagonal bracket 52 cooperate, the auxiliary diagonal bracket 52 increases the connection strength and stability between the length adjusting frame 4 and the main truss 1. It can transfer part of the pressure borne by the length adjusting frame 4 to the main truss 1, further dispersing the pressure and improving the overall truss's resistance to subsidence. The mounting base 51 and the auxiliary diagonal bracket 52 of the reinforcing bracket 5 are made of angle steel or channel steel, possessing high strength and stability.

[0037] The implementation principle of the anti-sinking truss in this embodiment is as follows: During actual assembly, two square tubes are placed parallel to each other, and then the sleeve part 211 of the support seat 2 is fitted onto the middle of the square tube. The support seat 2 and the square tube are fixed firmly by welding or bolting. The end sleeve 312 is fitted onto both ends of the square tube and fixed by bolting. The flip seat 32 is rotatably connected to the outer ear plate 313 by a pin, ensuring that the flip seat 32 can rotate flexibly. The head of the sleeve 41 is fitted onto the flip seat 32 and fixed by welding or bolting. The telescopic inner tube 42 is inserted into the lower end of the sleeve 41, and its length can be adjusted and locked by connecting bolts. The mounting seat 51 is fixed to the main truss 1 by welding or bolting. The head of the auxiliary inclined frame 52 is rotatably connected to the mounting seat 51 by a pin, and its lower end is fixedly connected to the sleeve 41 by bolts. In actual use, the length of the length adjustment frame 4 and the angle of the flip frame group 3 are adjusted according to the flatness of the ground and the actual support requirements, so that the lower end of the length adjustment frame 4 is stably supported on the ground. Meanwhile, the stability of the truss is further enhanced by strengthening the support 5, ensuring that the truss will not sink during the load-bearing process.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
