Description

Technical Field

[0001] This utility model relates to the field of surface construction of curved buildings, and specifically to a prefabricated construction frame for surface construction of curved buildings. Background Technology

[0002] The installation of hyperboloid stadium wall panels typically employs methods such as full-span scaffolding, mobile aerial work platforms, and suspended scaffolds. Because the radius of curvature of the hyperboloid wall varies, a large amount of scaffolding or work platforms of different sizes are required, resulting in relatively slow construction speed and significant material consumption for scaffolding and work platforms. Therefore, effectively reducing material consumption, minimizing costs, and increasing construction speed are crucial issues that the project needs to address.

[0003] Therefore, to solve the above problems, a prefabricated construction scaffold is needed for the construction of curved building surfaces, which can reduce the amount of materials used in construction measures, reduce construction costs, and increase construction speed. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the defects in the prior art and provide a prefabricated construction frame for the construction of curved building surfaces, which can reduce the materials used in construction measures, reduce construction costs, and increase construction speed.

[0005] The present invention relates to a prefabricated construction frame for curved building surface construction, comprising support segments, standard segments, and connecting mechanisms.

[0006] The connecting mechanism includes connecting part I, connecting part II, connecting part III, and connecting part IV;

[0007] The connecting part III is hinged to the connecting part I;

[0008] The connecting mechanism further includes an angle positioning component with the hinge axis between the connecting part III and the connecting part I as the axis, which is used to connect the connecting part III and the connecting part IV at a set angle.

[0009] The angle positioning assembly includes a connector having several positioning parts, a fastener I for cooperating with any of the positioning parts, and a fastener II for cooperating with any of the positioning parts.

[0010] The connecting part II is detachably assembled on the connector via fastener I, and the connecting part IV is detachably assembled on the connector via fastener II; so that by adjusting the fastener I and fastener II to be closer or farther away on the connector, the connecting part II and the connecting part IV are correspondingly moved closer or farther away.

[0011] In use, connecting parts I and II are connected to the support segment, and connecting parts III and IV are connected to the standard segment, so that the support segment and the standard segment are connected at a set angle by the connecting mechanism.

[0012] Furthermore, the connecting mechanism also includes an angle adjustment component, which includes a connecting part V, a connecting part VI, and a push-pull member. The push-pull member is used to move the connecting parts V and VI closer or further apart. The connecting part V is connected to the support segment, and the connecting part VI is connected to the standard segment.

[0013] Furthermore, the standard segment consists of several segments, and adjacent standard segments are connected by corresponding connecting mechanisms so that adjacent standard segments are connected at a set angle by adjusting the corresponding connecting mechanisms.

[0014] Furthermore, it also includes a counterweight assembly disposed on the support segment, the counterweight assembly being used to increase or decrease the weight of the support segment.

[0015] Furthermore, the counterweight assembly and the standard segment are respectively located at both ends of the support segment.

[0016] Furthermore, the support segment is provided with a traveling mechanism I for driving the support segment to travel along a predetermined route and lock it in a predetermined position.

[0017] Furthermore, the standard segment is equipped with a walking mechanism II for driving the standard segment along a predetermined route and locking it in a predetermined position.

[0018] Furthermore, the walking mechanism I and the walking mechanism II are far apart from each other in the height direction.

[0019] Furthermore, the standard segment has a ladder.

[0020] This solution also discloses a method for constructing curved building surface layers, including the prefabricated construction frame for constructing curved building surface layers; it also includes the following construction steps:

[0021] S1. Assemble support segments and standard segments at the construction site that have a curvature close to that of the curved building surface to be constructed;

[0022] S2. Transport the assembled support segments and standard segments to the top construction platform of the curved building to be constructed;

[0023] S3. Construction of curved building surface layer;

[0024] S4. Move the assembled support segment and standard segment to the next construction position, and repeat step S3;

[0025] If the curvature of the surface to be constructed at the next construction site is different from that at the previous construction site, the angle between the support segment and the standard segment is adjusted by the connecting mechanism to be close to the curvature of the surface to be constructed at the next construction site.

[0026] If the height of the construction surface of the curved building to be constructed at the next construction site increases or decreases, standard segments are added or removed through the connecting mechanism, and step S3 is repeated.

[0027] The beneficial effects of this utility model are as follows: The prefabricated construction frame disclosed in this utility model for the construction of curved building surfaces, through the use of the connecting mechanism, allows adjacent segments to actively adapt to the curvature of the corresponding irregular structure, replacing the rigid support structure with a flexible segmental structure, which greatly improves the adaptability of the construction device of this solution, reduces the on-site support construction, lowers costs, and is convenient to use, thus improving construction efficiency.

[0036] Figures 1-7 The figure shows a schematic diagram of the structure of this utility model. The prefabricated construction frame for curved building surface construction in this embodiment includes a support segment 1, a standard segment 2, and a connecting mechanism.

[0037] In this embodiment, the support segment 1 includes a support body with a U-shaped top opening. The lateral projection of the support body is trapezoidal. It also includes a sheet-like support frame that runs through the middle of the length of the support body. The sheet-like support frame is perpendicular to the bottom frame opposite the opening of the support body, and the sheet-like support frame and the bottom frame form a cross-shaped connection structure. The support body has a diagonal brace that connects the top and front end of the cross shape. In the lateral projection, the side of the support body with the diagonal brace is triangular.

[0038] The standard segment 2 is detachably assembled and disassembled on the support segment 1 via a connecting mechanism. The support segment 1 is used to set the entire device in a preset position. Taking the surface construction of a hyperboloid stadium as an example, the support segment 1 is set in the top gutter of the hyperboloid stadium, and the support segment 1 is equipped with a walking mechanism I3 for driving the support segment 1 along a predetermined route and locking it in a predetermined position. In this scheme, the walking mechanism I3 is set at the bottom of the sheet support frame, and the height of the walking mechanism I3 is adjustable. Specifically, the walking mechanism I3 is a walking wheel with a top rod. Several through holes are opened at the bottom of the support rod of the sheet support frame along the height direction. The top rod is fastened to any of the through holes by a connecting pin to realize the height adjustment of the walking mechanism I3. The walking mechanism I3 includes two sets corresponding to the number of support rods at the bottom of the sheet support frame to ensure support stability and walking stability. The walking wheel has a locking function so that it forms a stable support for the overall structure after being locked in a predetermined position. The walking mechanism can be assembled with a top rod with a connecting pin using any existing walking wheel structure with a locking function. This will not be elaborated further here.

[0039] The support body has a counterweight assembly 5 on the bottom frame of the side with the diagonal brace. The counterweight assembly 5 is used to increase or decrease the weight of the support segment 1. Specifically, the counterweight assembly 5 includes several counterweight plates.

[0040] Furthermore, the counterweight component 5 and the standard segment 2 are respectively located at both ends of the support segment 1. After the support segment 1 is set in the preset position, the counterweight component 5 is in the front and the standard segment 2 is in the back. In use, the standard segment 2 is used to support the construction personnel to carry out the construction of the surface layer of the curved building. In this solution, the standard segment 2 is set with several segments. Several standard segments 2 are connected in sequence through corresponding connecting mechanisms at a set angle to form a construction frame with a curvature radius similar to or the same as that of the construction site. This can realize the construction of the surface layer of the curved building with multiple construction positions, and can dynamically adjust the curvature of the construction frame, reduce the materials used in construction measures, reduce construction costs, and improve construction speed to achieve high efficiency in construction.

[0041] The support body has several uprights along the height direction on the bottom frame of the diagonal bracing side. Specifically, the uprights are arranged in two rows on the front horizontal section of the "+" shape. Each counterweight plate has mounting holes corresponding to several uprights. In use, the counterweight plate is dropped onto several uprights. The counterweight mass is adjusted by increasing or decreasing the number of counterweight plates stacked, which meets the support requirements of support segment 1, prevents the overall device from tipping over or shifting during use, and improves the application safety of the structure.

[0042] In this embodiment, the standard segment 2 includes a cylindrical truss with several bottom horizontal support rods at the bottom that serve as ladders. During construction, construction workers are protected inside the standard segment 2 and walk along the ladders. The standard segment 2 also has top horizontal support rods that can be used to suspend safety devices.

[0043] The standard segment 2 is equipped with a walking mechanism II4 for moving the standard segment 2 along a predetermined route and locking it in a predetermined position. The walking mechanism II4 acts as a driven component to guide the overall structure. In use, it is supported by the purlins or walls at the bottom of the building. The number of sets of walking mechanisms II4 can be set according to the actual situation. Its structure is the same as that of walking mechanism I3, and it has telescopic and locking functions so that it can be locked in a set position after adjusting the construction distance. In this scheme, the walking mechanism II4 and the walking mechanism I3 are far apart in the height direction. The walking mechanism II4 is set only on the bottom standard segment 2, opposite to the walking mechanism I3, so that the overall structure is erected on the construction curved surface, thereby increasing the construction space.

[0044] In this embodiment, the connecting mechanism includes connecting part I, connecting part II, connecting part III, and connecting part IV;

[0045] The connecting part III is hinged to the connecting part I; the hinge axis of the connecting part III and the connecting part I is parallel to the transverse direction, allowing free rotation in the height direction between adjacent support segments 1 and standard segments 2, as well as between adjacent standard segments 2, forming a whole and improving the reliability of the connection structure. This transforms the rigid connection of the construction frame into a flexible connection, providing a certain angle adjustment function, improving the applicability to irregular curved surfaces, and greatly reducing the on-site scaffolding setup and construction costs. The hinge structure connecting adjacent support segments 1 and standard segments 2, as well as between adjacent standard segments 2, is detachable and serves as a limiting structure for the rotating shaft and locking nut, improving the ease of disassembly and assembly of components, facilitating component turnover, and reducing construction costs.

[0046] The connecting mechanism also includes an angle positioning component 6, which uses the hinge axis between connecting part III and connecting part I as the axis to connect connecting part III and connecting part IV at a set angle. That is, after the adjacent segments are adjusted to the set angle, they are positioned at the set angle by the angle positioning component 6. This adds the feature of rigid connection on the basis of flexible connection, improving structural safety and stability. Moreover, the angle positioning component 6 is a detachable structure. In non-curved structures, the angle positioning component 6 can be disassembled and fixed by means of locking bolts to fasten the adjacent adjacent support segments 1 and standard segments 2, as well as the adjacent standard segments 2. This allows the device to be used as a fixed support, which has multi-functionality and versatility. It greatly improves the utilization rate of material turnover and reduces construction costs.

[0047] The angle positioning component 6 includes a connector with several positioning parts, a fastener I for cooperating with any of the positioning parts, and a fastener II for cooperating with any of the positioning parts; the connecting part II is detachably assembled and disassembled on the connector via the fastener I, and the connecting part IV is detachably assembled and disassembled on the connector via the fastener II; so that by adjusting the fastener I and the fastener II to be closer or farther away on the connector, the connecting part II and the connecting part IV are correspondingly moved closer or farther away.

[0048] In use, connecting parts I and II are connected to support segment 1, and connecting parts III and IV are connected to standard segment 2, so that support segment 1 and standard segment 2 are connected at a set angle by the connecting mechanism. Specifically, the connecting parts are elongated and have several mounting holes along their length as positioning parts. Fasteners I and II are bolts equipped with lock nuts. In use, the bolts with lock nuts pass through the positioning parts at the set positions to detachably assemble support segment 1, standard segment 2, and adjacent standard segment 2, and position them at the set angle. Connecting parts I, II, III, and IV are connected to support segment 1 and standard segment 2 respectively. The connection method is not limited to bolted assembly, welding, or integral molding, etc., and will not be described in detail here. In this design, connecting parts I, II, III, and IV are all integrally formed on the supporting segment 1 and the standard segment 2, respectively, and have through holes for fastener I or fastener II to pass through. Specifically, connecting part II is integrally formed at the upper rear end of the supporting segment 1, and connecting part I is integrally formed at the lower rear end. Connecting part IV is integrally formed at the upper front end or the lower rear end of each standard segment 2, and connecting part III is integrally formed at the lower rear end. This allows adjacent standard segments 2, as well as supporting segments 1 and standard segments 2, to be stably assembled through the connecting mechanism, and the angle can be adjusted accordingly to improve the stability of the connecting nodes and meet the requirements for angle-adjustable use.

[0049] In this embodiment, angle positioning components 6 are provided at corresponding positions on both sides of the support segment 1 and on both sides of the standard segment 2 to reduce the encroachment on the internal space and improve the reliability of the mechanism installation.

[0050] In this embodiment, the connecting mechanism further includes an angle adjustment component 7, which includes a connecting part V, a connecting part VI, and a push-pull member 10. The push-pull member 10 is used to move the connecting part V and the connecting part VI closer or further apart. The connecting part V is connected to the support segment 1, and the connecting part VI is connected to the standard segment 2.

[0051] The angle adjustment component 7 in this solution is provided in only one set, which includes an upper pull plate 8 used as a connecting part V and a lower pull plate 9 used as a connecting part VI, as well as any of the existing lifting cylinders used as a push-pull component 10.

[0052] like Figure 6 As shown, the lifting cylinder is used in pairs. The cylinder bodies of the two lifting cylinders are fixed on the pull-down plate 9, and the push rod is hinged on the pull-up plate 8, which is similar to a four-bar linkage mechanism. It is intended to bring the pull-up plate 8 and the pull-down plate 9 closer or further apart at a preset angle, and to stably pull the pull-up plate 8 and the pull-down plate 9. It will not be described in detail here. The hinge axis of the lifting cylinder is parallel to the hinge axis of the connecting part III and the connecting part I, so as to adapt to the use requirements of different angles.

[0053] Specifically, in use, the upper pull plate 8 is set on the upper support segment 1 or standard segment 2, and the lower pull plate 9 is set on the lower standard segment 2. The upper pull plate 8 and the lower pull plate 9 are inserted into the crossbar at the end of the corresponding support segment 1 or standard segment 2. After the crossbar at the end of the corresponding support segment 1 or standard segment 2 is adjusted, a support and limiting structure is formed.

[0054] During initial installation, support segments 1 and standard segments 2 with similar curvatures are assembled on the construction site. First, the angle between adjacent support segments 1 and standard segments 2 or adjacent standard segments 2 is adjusted using angle adjustment components 7. Then, adjacent support segments 1 and standard segments 2 or adjacent standard segments 2 are assembled using angle positioning components 6. The assembly order is not limited on the construction site. If high-level assembly is required, it is done from top to bottom to ensure structural reliability.

[0055] During subsequent adjustments, i.e., dynamically adjusting the angle of the corresponding standard segment 2 at a high position, the angle adjustment component 7 is first used to limit the angle between the adjacent support segment 1 and the standard segment 2 or the adjacent standard segment 2. Then, the angle positioning component 6 at the corresponding location is disassembled. Subsequently, the angle between the adjacent support segment 1 and the standard segment 2 or the adjacent standard segment 2 is adjusted by the angle adjustment component 7. The angle positioning component 6 at the corresponding location is then reassembled. The assembly is carried out from top to bottom to ensure the reliability of the structure.

[0056] During construction, a crane is generally used to hoist the entire assembly to the preset position. When moving, only the power equipment is needed to push the entire structure to move. The structure of the entire construction frame is simple, without any unnecessary structural reinforcements or other auxiliary components. The structure is significantly lightweight and comes with its own walking mechanism I3 and walking mechanism II4, making it convenient to use and facilitating quick and easy construction.

[0057] This solution also discloses a method for constructing curved building surface layers, including the prefabricated construction frame for constructing curved building surface layers; it also includes the following construction steps:

[0058] S1. Assemble support segments 1 and standard segments 2 at the construction site, which have a curvature close to that of the building surface to be constructed. Counterweight components 5 can be set at this step or after subsequent hoisting, depending on the construction conditions. This will not be elaborated further here.

[0059] S2. Transport the assembled support segment 1 and standard segment 2 to the top construction platform of the curved building to be constructed;

[0060] S3. Construction of curved building surface layer;

[0061] S4. Move the assembled support segment 1 and standard segment 2 to the next construction position, and repeat step S3;

[0062] If the curvature of the surface to be constructed at the next construction site is different from that at the previous construction site, the angle between the support segment 1 and the standard segment 2 is adjusted through the connecting mechanism to be close to the curvature of the surface to be constructed at the next construction site.

[0063] If the height of the construction surface of the curved building to be constructed at the next construction site increases or decreases, standard segment 2 is added or removed through the connecting mechanism;

[0064] S5. Repeat steps S3 and S4 until construction is complete.

[0065] The construction method described in this plan requires only one hoisting of the scaffold. During subsequent structural adjustments and relocations, the high-level construction method fully utilizes the scaffold's characteristics, reducing construction costs and significantly shortening the construction period.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
