Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a foldable umbrella-shaped multi-span linkage scaffold and an automated installation and disassembly method thereof. Background Art

[0002] In the field of modern construction engineering, full-height support scaffolding is an important temporary support system, but its technical development is still significantly insufficient. Although the traditional scaffolding system represented by ordinary steel pipe fastener type and disc fastener type can meet the basic needs in terms of structural rigidity and bearing capacity, it has systematic technical bottlenecks in terms of construction efficiency, safety performance and economy. Specifically, it is manifested as follows:

[0003] 1. The lack of modular design leads to cumbersome erection and dismantling procedures. The current scaffolding adopts a discrete rod connection system. The construction process needs to go through many basic processes such as material classification and handling, layered assembly, and step-by-step reinforcement. The whole process relies on manual handling and erection. Taking the disc-type full-floor support scaffolding as an example, its erection process generally goes through the process of carrying whole bundles of materials, laying out material parts, erecting the base and sweeping rods, extending the vertical poles layer by layer, connecting the horizontal poles layer by layer, and reinforcing the diagonal braces. Similarly, during the dismantling process, the vertical poles, horizontal poles, and diagonal poles must be dismantled layer by layer from top to bottom, and the dismantled parts must be bundled regularly and finally transported in bundles. Since the scaffolding system contains many types of basic components and a large number of special accessories, and the entire operation process is manual, the modularity of the frame structure is low. Especially in scenarios where multiple turnovers are required, the cumbersome erection and dismantling procedures greatly increase the construction cost and time cost, seriously affecting the construction efficiency.

[0004] 2. There are hidden safety hazards in high-altitude operations. At the working level with a height of more than 2m, construction workers need to manually climb the frame. Statistics show that 68% of high-fall accidents in scaffolding construction occur during the horizontal rod connection process, and the main reason is the local deformation of the frame caused by the instability of temporary supports.

[0005] 3. Insufficient reliability of diagonal bracing. The traditional diagonal bracing system adopts discrete layout, and its node connection reliability coefficient is low. Under the action of dynamic load, the lateral displacement of the frame can reach 1.5-2 times the design value. Especially in the concrete pouring stage, the probability of resonance between the frame vibration frequency and the construction machinery increases, posing a major safety hazard.

[0006] The above technical defects have formed a multi-dimensional bottleneck that restricts the development of the scaffolding system. The traditional scaffolding system can no longer meet the comprehensive requirements of modern construction for modularization, intelligence, and safety. It is urgent to build a new scaffolding system with self-balancing and adaptive characteristics through structural innovation to achieve a systematic breakthrough in construction efficiency, safety performance, and technical and economic indicators.

[0026] S04: on the foldable unit of step S02, a plurality of A-type foldable units are spliced ​​and connected in the longitudinal direction to form an A-type linked foldable strip frame including a certain number of foldable units in the longitudinal direction;

[0027] S05: On the B-type foldable unit of step S03, multiple B-type foldable units are spliced ​​and connected along the longitudinal direction to form a B-type linked foldable strip frame including a certain number of foldable units in the longitudinal direction.

[0032] S014: Take the pin and the other end of the diagonal rod with the diagonal rod reaming hole to achieve hinge connection;

[0033] S015: Insert the slider guide crossbar into the bidirectional slider.

[0034] Furthermore, a method for quickly erecting and dismantling a foldable umbrella-shaped multi-span linkage scaffold is provided, comprising the following steps:

[0035] Quick setup process:

[0036] M01: transporting a certain number of type A linked foldable strip frames and type B linked foldable strip frames described in step S04 and step S05 to the construction area according to the design size requirements;

[0037] M02: According to the design plane position, a certain number of type A linked foldable strip frames and type B linked foldable strip frames described in step M01 are positioned, unfolded, and the sliders are locked to form a number of strip-shaped statically indeterminate trusses whose basic unit side projection shapes are "flat" and whose top rods are all triangularly hinged;

[0038] M03: alternately splicing the strip-shaped statically indeterminate trusses formed by unfolding the A-type linked foldable strip-shaped frame in step M02 and the strip-shaped statically indeterminate trusses formed by unfolding the B-type linked foldable strip-shaped frame to form a full-height scaffolding frame of a certain width and length; thus, the rapid erection process of the foldable scaffolding is completed;

[0039] Quick removal process:

[0040] F01: Adjust the height adjustment nuts of all the vertical bars on the B-type linkage foldable bar frame, lower the B-type linkage foldable bar frame, and separate the bracket pin hole on the top of the B-type linkage foldable bar frame from the crossbar pin of the A-type crossbar.

[0043] The beneficial effect of the present application is that: by pre-assembling scattered support components into frame units, and then further bridging these frame units into foldable units, and finally combining the foldable units to form two types of foldable strip frames, type A and type B, and by alternately using type A and type B strip frames for erection, a scaffolding structure that meets the construction design requirements can be quickly constructed. This innovative construction method not only improves construction efficiency, but also ensures the stability and safety of the structure during construction.

[0044] The following technical advantages can be achieved by using the scaffolding and the installation and disassembly method of the present application:

[0045] First, by forming modular design units, the use of discrete parts can be significantly reduced, which not only reduces the number of connection nodes, but also simplifies the assembly process. This modular design makes the scaffolding erection and dismantling process faster and more convenient, thereby greatly improving the scaffolding reuse rate and reducing material waste.

[0046] Secondly, since the scaffolding design of the present application reduces the reliance on manual labor, it can effectively reduce the incidence of high-fall accidents caused by improper manual operation. This not only improves the safety of construction workers, but also reduces project delays and cost increases caused by accidents.

[0047] Finally, each frame unit presents an "umbrella"-like structure when folded, and a "flat"-like structure when unfolded. This unique umbrella-flat conversion frame mechanism is not only highly innovative, but also highly stable and reliable. This design is particularly suitable for working environments that need to withstand dynamic loads and can meet the needs of operations under various complex construction conditions.

[0073] The specific implementation methods of the present application are described below in conjunction with the accompanying drawings so that those skilled in the art can better understand the present application.

[0074] like Figure 1-17 As shown, a foldable umbrella-shaped multi-span linkage scaffold and an installation and disassembly method thereof are provided.

[0075] like Figure 1 As shown, the basic frame unit of the scaffolding of this application comprises: a vertical pole 1, two longitudinal cross bars 2, three transverse cross bars 3, a slider guide cross bar 4, a bidirectional slider 5 and two diagonal bars 6;

[0076] like Fig. 9 As shown, the vertical pole 1 is composed of a slider guide vertical pole 12, a vertical extension vertical pole 13, a height adjustment nut 14, a height adjustment screw rod 15 and a base 16 from top to bottom. The top of the slider guide vertical pole 12 is provided with a vertical pole ear hole 11. The height adjustment nut 14 is connected to the height adjustment screw rod 15 through the thread hole. The height adjustment nut 14 can rotate freely around the axis of the height screw rod 15 and can continuously adjust the height of the vertical pole 1 within a certain range. The slider guide vertical pole 12 is provided with a slider vertical limit device 17, which is composed of a slider limit baffle 171 and a slider vertical limit pin hole 172.

[0077] A longitudinal cross bar ear hole 21 is respectively provided at both ends of the longitudinal cross bar 2 .

[0078] like Figure 10-11 As shown, the transverse crossbar 3 includes two types of crossbars, type A and type B, wherein the two ends of the type A crossbar are provided with crossbar latches 321, and the two ends of the type B crossbar are provided with crossbar brackets 311 and bracket pin holes 312 opened in the crossbar brackets.

[0079] like Fig.13 As shown, a slider transverse limiting device 41 is provided on the slider guide crossbar 4, and the slider transverse limiting device 41 is composed of two groups of slider transverse limiting pin holes 411 and purchased pins.

[0080] like Fig.14 As shown, the bidirectional slider 5 includes a slider body 50, on which a transverse sliding hole 52 and a vertical sliding hole 53 are provided. Both the transverse sliding hole 52 and the vertical sliding hole 53 are through holes and intersect vertically in a three-dimensional space. The transverse sliding hole 52 is sleeved on the slider guide crossbar 4 for horizontal sliding, and its transverse adjustment is controlled by the slider transverse limit device 41. The vertical sliding hole 53 is sleeved on the vertical bar 1 for up and down sliding, and its vertical adjustment is controlled by the slider vertical limit device 17. A slider transverse connecting sleeve 54 is provided on the transverse sliding hole 5, and the transverse sliding hole 5 and the slider transverse connecting sleeve 54 are arranged vertically.

[0081] The sliding principle of the bidirectional slider 5 in the vertical and horizontal directions is as follows:

[0082] Vertical direction: When the frame is fully extended, the upper end of the vertical sliding hole 53 of the two-way slider 5 contacts the lower end of the slider limit stop plate 171, and the lower end of the vertical sliding hole 53 corresponds to the upper end of the slider vertical limit pin hole 172; when the vertical sliding hole 53 of the two-way slider 5 contacts the slider limit stop plate 171, it indicates that the frame has been fully extended. At this time, by inserting the pin into the slider vertical limit pin hole 172, the position of the two-way slider 5 on the vertical pole 1 is fixed. If the fixation needs to be released, just pull out the pin, and the two-way slider 5 can slide freely on the vertical pole 1.

[0083] Horizontal direction: The distance between the two sets of slider horizontal limit pin holes 411 is equal to the length of the horizontal sliding hole 52 of the bidirectional slider 5. When the slider limit pin is not inserted into the slider limit pin hole 411, the bidirectional slider 5 can slide freely horizontally on the slider guide cross bar 4; once the slider limit pin is inserted into the slider limit pin hole 411, the bidirectional slider 5 is locked on the slider guide cross bar 4 and cannot slide freely.

[0084] like Figure 1 As shown, an oblique rod ear hole 61 is provided at one end of the oblique rod 6, and an oblique rod reaming hole 62 is provided at the other end.

[0085] Step S01: The basic frame unit is connected in the following manner:

[0086] S011: Select a transverse crossbar 3 and two longitudinal crossbars 2, insert the transverse crossbar 3 into the longitudinal crossbar ear holes 21 at one end of the two longitudinal crossbars 2 and the vertical rod ear holes 11 at the top of the vertical rod 1, and after hinged connection, realize the connection between the transverse crossbar 3, the two longitudinal crossbars 2 and the top of the vertical rod 1;

[0087] S012: Take a bidirectional slider 5 and install it on the vertical rod 1. The specific operation is to make the vertical rod 1 pass through the vertical sliding hole 53 of the bidirectional slider 5;

[0088] S013: Select two transverse crossbars 3 and two diagonal bars 6, and respectively pass the two transverse crossbars 3 through the longitudinal crossbar ear holes 21 at the other ends of the two longitudinal crossbars 2 described in step S011, and the diagonal bar ear holes 61 of the two diagonal bars, so as to achieve the top connection of the transverse crossbars 3, the longitudinal crossbars 2 and the diagonal bars 6 on both sides;

[0089] S014: Take pins to respectively hinge the oblique rod reaming holes 62 at the other ends of the two oblique rods 6 with the slider reaming holes 51 on both sides of the two-way slider 5, so as to realize the connection between the two oblique rods 6 and both sides of the two-way slider 5;

[0090] S015: Insert the slider guide cross bar 4 into the transverse sliding hole 52 of the bidirectional slider 5.

[0091] Connected in the above manner, the vertical pole 1, the longitudinal cross bar 2, the transverse cross bar 3, the slider guide cross bar 4, the two-way slider 5, and the diagonal rod mechanism 6 can form a basic frame unit whose side projection shape is an "umbrella" shape (when folded or half-folded) or a "flat" shape (when fully unfolded).

[0092] After completing the assembly of the basic frame unit, the two basic frame units are further arranged in parallel, and the bidirectional sliders 5 of the two basic frame units are connected by the slider connecting cross bar 7. The connection method is that the two ends of the slider connecting cross bar 7 are directly inserted into the slider transverse connecting sleeves 54 of the two basic frame units, thereby forming a basic folding unit.

[0093] like Figure 3-Figure 5 As shown, the frame folding unit is in an "umbrella"-shaped semi-folded state, a fully folded state, and a "flat" state after unfolding.

[0094] According to the different end structures of the transverse crossbar 3, the A-type foldable unit and the B-type foldable unit are assembled respectively. The specific steps are as follows:

[0095] Step S02: Assembling the A-type foldable unit: Select a transverse crossbar 3 with a crossbar latch 321 at the end to assemble the frame unit of step S01, and set two such frame units in parallel. The tops of the two frame units share the transverse crossbar 3, and the two bidirectional sliders 5 corresponding to the two frame units are connected by the slider connecting crossbar 7 to form an A-type foldable unit;

[0096] Step S03: Assembling the B-type foldable unit: Select a transverse crossbar 3 with a crossbar bracket 311 and a bracket pin hole 312 provided in the crossbar bracket at the end to assemble the frame unit of step S01, and set two such frame units in parallel. The tops of the two frame units share the transverse crossbar 3, and the two bidirectional sliders 5 corresponding to the two frame units are connected by the slider connecting crossbar 7 to form a B-type foldable unit;

[0097] Step S04: on the foldable unit of step S02, a plurality of A-type foldable units are spliced ​​and connected along the longitudinal direction to form an A-type linked foldable strip frame including a certain number of foldable units in the longitudinal direction;

[0098] Step S05: on the B-type foldable unit of step S03, multiple B-type foldable units are spliced ​​and connected along the longitudinal direction to form a B-type linked foldable strip frame including a certain number of foldable units in the longitudinal direction;

[0099] A schematic diagram of the A-type linkage foldable strip frame or the B-type linkage foldable strip frame in a semi-folded state is shown in FIG. Figure 6 , see the fully folded state diagram Figure 7 , the fully expanded state is shown in Figure 8 As shown. The specific process of the foldable strip frame from the semi-folded state to the unfolded state is as follows: first, all the slider vertical limit devices 17 and slider horizontal limit devices 41 on the strip frame are loosened, and then the slider connecting cross bars 7 at both ends of the strip frame are lifted up to a certain height by a forklift or an AGV transport trolley with a lifting device. At this time, due to the supporting effect of the two-way slider 5 and the slider guide cross bar 4, the entire strip frame together with the vertical pole 1 will be lifted up; then, a forklift or an AGV transport trolley with a lifting device is used to stretch and unfold the frame along the longitudinal ends until the top longitudinal cross bars 2 of all basic frame units are on the same plane. At this time, all the slider vertical limit devices 17 and slider horizontal limit devices 41 on the strip frame are locked, and the entire strip frame can form an over-static truss structure composed of triangular units with vertical pole legs; then, the lifting height of the forklift or AGV transport trolley is reduced, and the frame is placed on the ground.

[0100] like Fig.15 and Fig.16 As shown, a method for quickly erecting a foldable umbrella-shaped multi-span linkage scaffold is provided, comprising the following steps:

[0101] M01: transporting a certain number of type A linked foldable strip frames and type B linked foldable strip frames described in step S04 and step S05 to the construction area according to the design size requirements;

[0102] M02: According to the design plane position, a certain number of type A linked foldable strip frames and type B linked foldable strip frames described in step M01 are positioned, unfolded, and the sliders are locked to form a number of strip-shaped statically indeterminate trusses whose basic unit side projection shapes are "flat" and whose top rods are all triangularly hinged;

[0103] M03: Alternately splice the statically indeterminate strip trusses formed by unfolding the A-type linked foldable strip frame in step M02 and the statically indeterminate strip trusses formed by unfolding the B-type linked foldable strip frame to form a full-height scaffolding frame of a certain width and length; during the alternating splicing process, the crossbar latch 321 of the A-type crossbar is directly inserted into the bracket pin hole 312 of the B-type crossbar to achieve the transverse connection between the A-type and B-type crossbars (see Fig.12 ).

[0104] At this point, the rapid erection process of the foldable scaffolding is completed.

[0105] like Fig.17 The figure shows the final three-dimensional state of the assembled scaffolding.

[0106] After the work is completed, when it is necessary to Fig.17 When the scaffold is dismantled, the rapid dismantling method comprises the following steps:

[0107] F01: Adjust the height adjustment nuts of all the vertical bars on the B-type linkage foldable bar frame, lower the B-type linkage foldable bar frame, and separate the bracket pin hole on the top of the B-type linkage foldable bar frame from the crossbar pin of the A-type crossbar.

[0108] F02: Loosen all the vertical limit devices and horizontal limit devices of the slider on the B-type linkage foldable strip frame, fold the B-type linkage foldable strip frame and transport it to the next construction area;

[0109] F03: Loosen all the vertical limit devices and horizontal limit devices of the slider on the A-type linkage foldable strip frame, fold the A-type linkage foldable strip frame and transport it to the next construction area, until all the A-type linkage foldable strip frames and B-type linkage foldable strip frames are folded and transported, and the rapid dismantling process of the foldable scaffolding is also completed.

All equivalent structural changes made using the present application are included in the protection scope of the present application.
