Description

Technical Field

[0001] This application relates to the field of scaffolding construction technology, and in particular to an adjustable support structure for disc-lock scaffolding. Background Technology

[0002] As a core support equipment in the construction field, modular scaffolding is widely used in housing construction, bridge engineering, tunnel construction and other scenarios. It mainly undertakes key functions such as formwork support, construction personnel operation platform construction, and material stacking and bearing. Its structural stability directly determines construction safety and project quality.

[0003] In existing technologies, the construction process of disc-lock scaffolding usually follows these steps: First, a base is laid on the concrete foundation or hardened ground of the construction site. Then, the uprights (vertical load-bearing components of the scaffolding) are inserted into the base and connected to the horizontal and diagonal braces (lateral and diagonal stabilizing components) through the connecting discs on the uprights to form a three-dimensional support frame. Finally, the scaffolding is built layer by layer upwards according to the construction height requirements.

[0004] Traditional scaffolding bases are mostly fixed-height structures, only suitable for single flat foundations. When the construction site has undulating terrain or foundation elevation deviations (such as uneven concrete pad thickness), the height of the uprights cannot be flexibly adjusted, making it difficult to guarantee the verticality of the scaffolding uprights. This leads to uneven stress on the frame and increases the risk of collapse. Furthermore, the outer sleeves of existing starting uprights generally use an upward-opening design. When the upright connects to the base, the weld of the outer sleeve directly bears the weight of the upright, construction loads, and horizontal impact forces. Long-term stress can easily cause weld cracking and detachment, which can directly lead to local instability of the scaffolding and cause safety accidents. At the same time, the upward-opening outer sleeve design allows rainwater, construction dust, concrete residue, and other debris to enter the sleeve, which is difficult to clean. Long-term accumulation accelerates corrosion of the inner wall of the upright, shortening the service life of the components. Corroded uprights have reduced connection precision, increasing disassembly difficulty and further increasing construction and maintenance costs and the risk of project delays. Utility Model Content

[0005] To address or partially address the problems existing in related technologies, this application provides an adjustable support structure for disc-type brackets, which achieves height adjustment through an adjustable base and uses a downward-facing outer base to avoid stress on the weld seams of the connecting sleeves on the uprights.

[0006] The first aspect of this application provides an adjustable support structure for a disc-type bracket, comprising: a base plate, a lead screw, a connecting disc, an outer base, a sleeve, and a vertical pole. The lead screw is vertically connected to the middle of the base plate. The connecting disc and the outer base are sleeved on the outside of the lead screw, with the bottom of the outer base abutting against the upper end of the connecting disc. The connecting disc and the outer base can move along the axial direction of the lead screw and are fixed by a nut. A limiting member is provided in the middle of the outer base, and a pin hole is opened at the top. The sleeve is sleeved on the top of the outer base and abuts against the limiting member. A fixing hole is opened on the sleeve corresponding to the pin hole and fixed by the connecting member. The sleeve is located at the bottom of the vertical pole.

[0007] The connector is a flexible pin or cotter pin with an anti-slip design.

[0008] The connecting plate has eight octagonal or eight circular eight-hole plates evenly distributed on it, which are used to connect with horizontal bars and diagonal bars.

[0009] The limiting component is an annular boss set on the outer sleeve base, used to limit the axial displacement of the sleeve.

[0010] The nuts include a fixing nut installed on the top of the outer base and an adjusting nut installed on the bottom of the connecting plate. The top surface of the fixing nut is flush with the top surface of the outer base, and the outer diameter of the fixing nut is less than or equal to the outer diameter of the outer base.

[0011] The technical solution provided in this application may include the following beneficial effects: This application provides an adjustable support structure for disc-lock scaffolding. Height adjustment is achieved through an adjustable base. A downward-facing connection method is used to connect the upright sleeve to the base, allowing the load of the upright to be transferred to the base via the outer base. This avoids direct stress on the weld seams, eliminating the risk of cracking and weld detachment caused by uncontrollable weld quality, and significantly improving the vertical load-bearing safety of the scaffolding. The downward-facing design effectively prevents rainwater, dust, concrete residue, and other debris from entering the pipe, reducing the risk of corrosion on the inner wall of the upright from the source.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0019] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1An adjustable support structure for a disc-type bracket is shown, comprising: a base plate 1, a lead screw 2, a connecting disc 3, an outer base 4, a sleeve 5, a vertical pole 6, an adjusting nut, and a fixing nut. The base plate 1 is made of thick steel plate with a large area, effectively distributing the load and ensuring stable placement of the base. The lead screw 2 is vertically welded to the center of the base plate 1, and its surface has external threads. It cooperates with the adjusting nut to coarsely adjust the height. The connecting disc 3, the outer base 4, and the sleeve 5 are sequentially fitted onto the outer side of the lead screw 2 from bottom to top. For ease of installation, the connecting disc 3 is welded to the bottom of the outer base 4. The rigid assembly formed by the outer base 4 and the connecting disc 3 is moved axially along the lead screw 2 by rotating the adjusting nut and fixed by the fixing nut. The inner wall of the outer base 4 has a clearance fit with the lead screw 2, allowing axial movement but restricting circumferential rotation. The length of the lead screw 2 is greater than the sum of the length of the outer base 4 and the maximum adjustable height, ensuring that even at the highest position, the top of the outer base 4 is still lower than the top of the lead screw 2.

[0021] like Figure 2 As shown, the outer base 4 has a limiting member in the middle and a pin hole at the top. The limiting member is an annular boss on the outer base 4, used to limit the axial displacement of the sleeve 5. The sleeve 5 is fitted onto the top of the outer base 4 and abuts against the limiting member. The sleeve 5 is a connecting structure welded to the bottom of the upright 6 for connecting the upright 6. The sleeve 5 has a fixing hole corresponding to the pin hole and is fixed based on the connecting member to fix the upright 6 and prevent it from being pulled out. The connecting member is an elastic pin or cotter pin with an anti-slip design. The elastic pin has an annular anti-slip barb on its surface. After being inserted into the fixing hole, the barb locks into the hole wall. After the cotter pin is inserted, the tail end is bent at an angle of ≥60° to prevent axial pull-out. The bottom of the outer base 4 abuts against the upper end of the connecting plate 3. The connecting plate 3 has 8 octagonal or 8 annular eight-hole plates evenly distributed on it for connecting with horizontal bars and diagonal bars.

[0022] A fixing nut is installed on the top of the outer base 4 and works in conjunction with an adjusting nut installed on the bottom of the connecting plate 3. The lead screw 2 passes through the adjusting nut, the connecting plate 3 + outer base 4, and the fixing nut in sequence. The connecting plate 3 and the outer base 4 are welded and fixed. The adjusting nut presses upward against the bottom surface of the connecting plate 3, and the fixing nut presses downward against the top surface of the outer base 4, forming a "paired clamping" state. The adjusting nut presses upward against the bottom surface of the connecting plate 3, restricting the rigid component from sliding downward along the lead screw 2; the fixing nut presses downward against the top surface of the outer base 4, restricting the rigid component from moving upward along the lead screw 2. The two work together to "lock" the component at a fixed height on the lead screw 2, eliminating the risk of vertical displacement.

[0023] The top surface of the fixing nut is flush with the top surface of the outer base 4, and the outer diameter of the fixing nut is less than or equal to the outer diameter of the outer base 4. A countersunk groove is machined on the top of the outer base 4, and the depth of the countersunk groove is equal to or slightly greater than the thickness of the fixing nut. This ensures that after the fixing nut is tightened, it is flush with the top surface of the outer base 4, allowing the sleeve 5 to be fitted into the outer base 4 without obstruction by the nut, and that it is tightly fitted by the bottom surface of the sleeve and the bottom of the countersunk groove. The adjusting nut is a nylon lock nut, and the nylon ring on its inner wall fits tightly with the external thread of the lead screw 2 after tightening, forming an anti-loosening self-locking mechanism.

[0024] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the units can be selected to achieve the purpose of this embodiment according to actual needs.

[0026] Furthermore, the functional units in the various embodiments of this application can be integrated into one processing unit, or each unit can exist physically separately, or two or more units can be integrated into one unit.
