Description

TECHNICAL FIELD

[0001] The application relates to the technical field of roof steel structure frame layer construction, in particular to a roof steel structure frame layer installation method and a sliding positioning device. BACKGROUND

[0002] Some steel structure frame layers are designed according to planning needs for a house building roof, for example, as a support structure of a curtain wall keel or a photovoltaic support, so as to facilitate the installation of a curtain wall or a photovoltaic panel. The steel structure frame layer is usually composed of main trusses, secondary beams, supports and purlines, and is designed as a spatial grid or a planar truss system. The length of a single frame of some steel structure frame layers is 15-40 m, the weight is 5-50 t, the installation elevation is more than 30 m from the ground, and in addition to bearing the load of the curtain wall or the photovoltaic panel, the steel structure frame layer also needs to meet the requirements of overall wind resistance, earthquake resistance and deformation control, so the cross section of the component is large, the node is complex, and high requirements are put forward for installation and deformation control.

[0003] At present, there are mainly two methods for installing the roof steel structure frame layer, namely the hoisting mechanical lifting method and the lifting equipment lifting method. The hoisting mechanical lifting method is to assemble the steel structure in blocks or in whole frames on the ground, and then use crawler cranes, truck cranes and other hoisting equipment to lift the components to the roof installation position according to the weight of the components, one or more times. When lifting in blocks, high-altitude secondary assembly is also required on the roof. The lifting equipment lifting method is to install a temporary lifting frame on the vertical components on the roof, and use multiple hydraulic jacks to vertically lift the frame layer assembled in whole or in blocks on the ground to the installation position. After the frame layer is fixed, the lifting frame and the jacks are removed.

[0004] However, the above two methods have obvious defects: 1. The hoisting mechanical lifting method requires high bearing capacity of the foundation for the hoisting machinery, and additional reinforcement is required for soft sites, resulting in prolonged construction period and increased cost. The turning radius of large-tonnage hoisting machinery is large, occupies a lot of space, and hinders the cross operation of surrounding processes. In addition, the selection of hoisting equipment is limited due to the limitation of building height, component weight and site space, and the safety risk is high. 2. In the lifting process of the lifting equipment lifting method, the stress condition of the component is often inconsistent with the design use condition, which requires re-calculation and possible additional reinforcement of the component, resulting in prolonged construction period and increased cost. The control of multiple hydraulic jacks in the vertical direction is difficult, and additional stress and deformation are easy to occur, which affects the installation precision. The lifting area needs to be fully enclosed, and the vertical space cannot be used, which seriously restricts the subsequent processes. At the same time, the processing of the lifting frame and the matching system takes a long time to install and remove, and the cost is high, which is not economical. SUMMARY

Unless otherwise specified, the above orientation description can be flexibly arranged in the actual application process under the condition of meeting the relative positional relationship shown in the drawings.

[0023] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] At present, there are mainly two methods for installing the roof steel structure frame layer, which are the hoisting machinery hoisting method and the lifting equipment lifting method. The hoisting machinery hoisting method is to assemble the steel structure in blocks or whole pieces on the ground, and then use crawler cranes, automobile cranes and other hoisting equipment to hoist it to the roof installation position according to the weight of the components, one or more times; when hoisting in blocks, high-altitude secondary assembly is also needed on the roof. The lifting equipment lifting method is to install a temporary lifting frame on the vertical components on the roof, and use multiple hydraulic jacks to vertically lift the frame layer assembled in whole or in blocks on the ground to the installation position, and then remove the lifting frame and jacks after the frame layer is fixed.

[0025] However, the above two methods have obvious defects: 1. The hoisting machinery hoisting method requires high bearing capacity of the foundation for the hoisting machinery, and the soft site needs additional reinforcement, which leads to the extension of the construction period and the increase of the cost; the turning radius of large-tonnage hoisting machinery is large, and it occupies more space, hindering the cross operation of the surrounding processes; and the selection of hoisting equipment is limited by the building height, component weight and site space, and the safety risk is high. 2. The lifting equipment lifting method often has inconsistent stress conditions and design use conditions during lifting, which needs to be recalculated and possibly reinforced additionally, leading to the extension of the construction period and the increase of the cost; the control of multiple hydraulic jacks in the vertical direction is difficult, and additional stress and deformation are easy to occur, affecting the installation precision; the lifting area needs to be fully enclosed, and the vertical space cannot be used, which seriously restricts the subsequent processes; at the same time, the lifting frame machine supporting system needs to be processed, and the installation and removal period is long, the cost is high, and the comprehensive economy is poor.

[0026] To solve the defects of the above two installation methods, the related technology proposes another installation method: first use the tower crane to hoist the parts for making the framework layer to the roof, and then assemble the complete framework layer at the installation position on the roof. However, this installation method still has the following defects: 1. The tower crane position is fixed, when the installation position of the framework layer exceeds the hoisting radius of the tower crane, the parts need to be adjusted to the roof first, and then manually or by small machine tools, the second time is dragged and moved to the installation position, which is labor intensive and low efficiency; 2. The framework layer is usually located on the outermost side of the roof or above the parapet wall, if directly assembled at the edge, the operation surface is narrow and has no reliable foothold, a cantilever operation platform and lifeline need to be set up, any time the component slips or the personnel loses balance will directly cause a high-altitude falling accident, the safety protection cost and supervision pressure increase dramatically.

[0027] Based on this, referring to Figure 1 , Figure 2 The embodiment of the present application provides a roof steel structure framework layer installation method, comprising: S1, dividing a making area 11 and an installation area 12 on the roof 1.

[0028] Specifically, referring to Figure 2 The making area 11 is the core area of the modular assembly of the roof steel structure framework layer, and its arrangement should meet the two requirements of one-time positioning of the tower crane and safe and efficient operation. For example, the making area 11 is preferentially arranged in the central area of the roof 1 within the hoisting radius of the tower crane, so that all parts such as rods, node plates and high-strength bolts can be hoisted into the making area 11 at one time, avoiding manual secondary handling, reducing labor intensity and high-altitude falling risk; a assembling platform is reserved in the central area, and high-edge protection and a safety channel are arranged around the central area, which ensures the cross-operation surface of multiple processes and provides sufficient buffer for measurement, welding, coating and other processes. The installation area 12 is the installation area of the roof steel structure framework layer, which can be determined according to the design drawing.

[0029] S2, dividing the steel structure framework layer into a plurality of standard modules 2 along the horizontal direction in the making area 11.

[0030] Specifically, when all parts such as rods, node plates and high-strength bolts are hoisted into the making area 11 by the tower crane, the steel structure framework layer can be divided into a plurality of standard modules 2 along the horizontal direction according to the design drawing. In this way, most of the welding and assembly work can be completed in the making area 11 on the roof 1 instead of in the air, which improves the construction quality and eliminates the safety risk of secondary assembly in the air.

[0031] S3, translating the standard module 2 from the making area 11 to the installation area 12 for installation.

[0032] Specifically, the various standard modules 2 are sequentially translated from the manufacturing area 11 to the installation area 12 according to the designed assembly sequence for installation and fixation; the flanges or splicing plates are pre-installed at the splicing positions of adjacent standard modules 2, and after being positioned, the assembly is completed at one time through high-strength bolts without the need for on-site welding. Since the standard modules 2 are manufactured in blocks along the horizontal direction, the top and bottom elevations and the relative sizes of the nodes are basically consistent, and after the standard modules 2 are translated into the installation area 12, only fine adjustment is needed by using jacks or adjusting supports, so that one-time positioning and permanent fixation can be achieved, and the entire process does not need secondary lifting or in-air turning, which eliminates the safety risks brought by high-altitude assembly, reduces the installation difficulty, and shortens the installation period.

[0033] The roof steel structure framework layer installation method provided by the embodiment of the application can complete most of the welding and assembly work in the manufacturing area 11 of the roof 1 instead of in the air, and replace the vertical lifting in the air with horizontal sliding, so that the working surface height is always controlled at the roof elevation, personnel do not need to work in the air for a long time, the safety risks are greatly reduced, the construction process can be cross-performed with other processes, and the site utilization rate is improved.

[0034] Compared with the hoisting mechanical lifting method, the application does not need a large-tonnage crawler crane or a truck crane, saves the foundation reinforcement and the time for large hoisting machinery to enter and exit the site, greatly shortens the construction period, and reduces the construction cost. Compared with the lifting equipment lifting method, the application does not need to install a temporary lifting frame, saves the lifting frame installation and removal time, shortens the construction period, and reduces the construction cost; the standard module is in a stress state consistent with the design working condition during translation, does not need to be additionally reinforced, avoids additional stress and deformation caused by synchronization error in vertical lifting, and improves the installation quality of the steel structure framework layer.

[0035] In some embodiments, referring to Figure 2 , in step S1, the support sliding frame 3 extending from the manufacturing area 11 to the installation area 12 is also laid on the roof 1; and in step S2, the standard module 2 is manufactured on the support sliding frame 3 in the manufacturing area 11.

[0036] Specifically, before the formal fabrication of the steel structure frame layer, a support sliding frame 3 is laid between the fabrication area 11 and the installation area 12. All standard modules 2 are positioned, welded, pre-assembled, and translated on the support sliding frame 3. The stiffness of the support sliding frame 3 has been verified by finite element analysis, providing rigid support for the standard modules 2 consistent with the design support reaction force. This ensures that the standard modules 2 maintain zero deflection and zero additional stress during translation, guaranteeing that the standard modules 2 are under the same stress condition as the design during horizontal sliding, avoiding secondary corrections due to changes in stress conditions. By fabricating the standard modules 2 on the support sliding frame 3, the prefabricated standard modules 2 can be directly translated to the installation area 12 along the support sliding frame 3 using a drive mechanism, eliminating the need for secondary hoisting, turning, or aerial assembly, thus eliminating the risks of high-altitude operations and improving construction efficiency.

[0037] In some embodiments, see Figure 3 , Figure 4 In step S1, the top of the supporting sliding frame 3 has several parallel positioning slots 311, which extend from the manufacturing area 11 to the installation area 12. Several evenly distributed stop blocks 4 are fixed at the bottom of the positioning slots 311. In step S3, several linear actuators 5 extending obliquely downward are hinged on the side of the standard module 2 away from the installation area 12. The linear actuators 5 correspond one-to-one with the positioning slots 311. The lower end of the linear actuator 5 extends into the corresponding positioning slot 311. The linear actuators 5 are controlled to extend and retract so that their lower ends abut against different stop blocks 4 to move the standard module 2 from the manufacturing area 11 to the installation area 12.

[0038] Specifically, the height of the stop block 4 is equal to or slightly lower than the groove depth of the positioning slot 311, providing a reliable fulcrum for the linear actuator 5 while ensuring no interference between the standard module 2 and the stop block 4 during sliding. The upper end of the linear actuator 5 is hinged to the standard module 2 via a horizontal pivot, allowing the linear actuator 5 to rotate up and down around the horizontal pivot. See also Figure 4 The left side of the diagram represents the manufacturing area 11, and the right side represents the installation area 12. The process of sliding the standard module 2 from the manufacturing area 11 to the installation area 12 using the linear actuator 5 is as follows: The lower end of the linear actuator 5 is placed in the positioning slot 311 and abuts against the right side of the leftmost stop block 4. The linear actuator 5 is then controlled to extend synchronously, and the downward thrust is counteracted by the stop block 4, pushing the standard module 2 one step to the right along the support sliding frame 3. The linear actuator 5 is then controlled to retract until its lower end passes the next stop block 4. This process is repeated until the standard module 2 is moved to the installation area 12. Correspondingly, this combination of positioning slot 311, stop block 4, and linear actuator 5, using a step-by-step pushing method, slides the standard module 2 from the manufacturing area 11 to the installation area 12. This method is simple in structure, convenient in operation, occupies little installation space, and requires no heavy-duty winch, making it safe and reliable.

[0039] In some embodiments, the linear drive 5 can adopt a single-acting or double-acting hydraulic cylinder, the cylinder body of which is hinged to the standard module 2 through a horizontally arranged pin shaft, so that the hydraulic cylinder can automatically adjust the swing angle along with the sliding of the standard module 2; the end of the piston rod of the hydraulic cylinder is used to abut against the stopper 4. When the piston rod is extended, a horizontal thrust is generated with the stopper 4 as the fulcrum, and when the piston rod is retracted, the next stopper 4 is passed and abuts against it, so as to realize step-by-step pushing.

[0040] In some embodiments, referring to Figure 4 , the linear drive 5 includes a hydraulic cylinder 51 and a setting slider 52, the cylinder body of the hydraulic cylinder 51 is used to be hinged to the standard module 2, the piston rod of the hydraulic cylinder 51 is hinged to the setting slider 52, and the end of the setting slider 52 away from the hydraulic cylinder 51 is used to abut against different stoppers 4 when the hydraulic cylinder 51 is extended or retracted.

[0041] Specifically, the cylinder body of the hydraulic cylinder 51 is hinged to the tail node of the standard module 2 through a hinge, and the end of the piston rod is hinged to the setting slider 52; the setting slider 52 is roughly wedge-shaped, and its lower surface is a guide slope and is subjected to hardening treatment. Referring to Figure 4 , in operation, the hydraulic cylinder 51 is extended to make the left end of the setting slider 52 abut against the right side of the stopper 4, and the right end of the setting slider 52 is supported above the next stopper 4; when the hydraulic cylinder 51 is retracted, the setting slider 52 is slid forward and passes the next stopper 4 under the guidance of the lower surface thereof; the above operation is repeated to realize step-by-step pushing. Correspondingly, the entire cycle has no rigid impact and low noise, and the setting slider 52 can be replaced individually after wear, further reducing maintenance cost.

[0042] In some embodiments, referring to Figure 3 , the support sliding frame 3 includes a plurality of support sliding setting channel steels 31 arranged in parallel and at intervals, and the grooves of the support sliding setting channel steels 31 form setting channels 311.

[0043] Specifically, each support sliding setting channel steel 31 can be fixed on the roof 1 through bolts or other fasteners, adjacent support sliding setting channel steels 31 can be welded together through connecting plates, and the grooves of the support sliding setting channel steels 31 are directed to and form the setting channels 311. Correspondingly, the support sliding frame 3 adopts a plurality of support sliding setting channel steels 31 arranged in parallel and at intervals, the grooves of which directly serve as the setting channels 311, one thing serving two purposes, which saves the process of welding additional tracks and greatly reduces the amount of on-site installation. The flanges and webs of the channel steels form a closed force ring with large torsional stiffness, which can provide a continuous, rigid and non-settling sliding surface for the standard module 2, ensuring that the step-by-step pushing process is always consistent with the designed stress working condition, and the sliding is stable and high in precision.

[0044] When the standard module 2 is sliding on the support sliding frame 3, the plurality of hydraulic cylinders 51 can be out of sync, and after the standard module 2 is slid to the installation area 12, it needs to be horizontally corrected. In order to reduce the correction workload of the standard module 2 after being slid to the installation area 12, in some embodiments, referring to Figure 3 、 Figure 5 , in step S1, the top of the support sliding frame 3 also has a guide groove 321 parallel to the setting groove 311, and the guide groove 321 extends from the manufacturing area 11 to the installation area 12; in step S3, the side of the standard module 2 towards the installation area 12 is connected with a guide sliding block 6 which is in sliding cooperation with the guide groove 321. Wherein, the guide sliding block 6 can be bolted with the standard module 2.

[0045] Correspondingly, by setting the guide groove 321 parallel to the setting groove 311 on the top of the support sliding frame 3, and slidingly cooperating the guide sliding block 6 connected with the standard module 2 in the guide groove 321, the standard module 2 is always guided by the cooperation of the guide sliding block 6 and the guide groove 321 during the step-by-step pushing process, forming a bidirectional constraint structure of front guiding and rear pushing, avoiding the transverse deviation of the standard module 2 due to the out-of-sync of the plurality of hydraulic cylinders 51, reducing the correction workload of the standard module 2 after being slid to the installation area 12, and improving the installation efficiency of the standard module 2.

[0046] In some embodiments, referring to Figure 3 , the support sliding frame 3 further comprises a plurality of support sliding guide channel steels 32 which are arranged in parallel and at intervals, and the inner cavity of the support sliding guide channel steel 32 forms the guide groove 321.

[0047] Specifically, the support sliding guide channel steel 32 can be fixed on the roof 1 by bolts and other fasteners, and the support sliding guide channel steel 32 and the support sliding setting channel steel 31 can also be welded together through the connecting plate, and the recess of the support sliding guide channel steel 32 faces and forms the guide groove 321. The top of the support sliding guide channel steel 32 is flush with the top of the support sliding setting channel steel 31 to form a support sliding surface for supporting and sliding the standard module 2.

[0048] Referring to Figure 3 、 Figure 4 , the embodiment of the application provides a roof steel structure framework layer sliding setting device, which comprises a support sliding frame 3, the top of the support sliding frame 3 has a plurality of parallel setting grooves 311, the bottom of the setting groove 311 is fixed with a plurality of evenly distributed stoppers 4, the upper side of each setting groove 311 is provided with an inclined linear actuator 5, the upper end of the linear actuator 5 is used for hinging the standard module 2 arranged on the support sliding frame 3, and the lower end of the linear actuator 5 is arranged in the setting groove 311 and abuts against different stoppers 4 when being stretched and retracted.

[0049] The embodiment of the application provides a roof steel structure frame layer sliding setting device, which is combined by a setting groove 311, a stop block 4 and a linear driver 5, adopts a step pushing mode, and can slide a standard module 2 from a manufacturing area 11 to an installation area 12 along a support sliding frame 3, is simple in structure, convenient to operate, small in occupied installation space, and safe and reliable without heavy hoists in the whole process.

[0050] The above is only a specific embodiment of the application, but the protection scope of the application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the application, which should be covered in the protection scope of the application.
