Technical Field

[0001] The present invention belongs to the technical field of building construction, and in particular relates to a common rail method for a construction elevator and an integrated intelligent construction platform for facade operations. Background Art

[0002] In the field of cast-in-place buildings and prefabricated buildings, the installation method of outdoor rail-type construction elevators is usually to set up a separate track for operation, which is distinguished from the operating equipment such as the buckle frame, steel pipe frame, and climbing frame of the main structure of the on-site construction. This method has high requirements on the on-site foundation and needs to deliberately avoid interference with the main structure construction equipment. It is also necessary to set up separate columns as elevator operation tracks, and it is necessary to carry out separate on-site vertical adjustment and measurement. The process is relatively cumbersome, the safety of the interlayer attachment is low, the construction cost is high, and it needs to be improved. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses a common track method for a construction elevator and an integrated intelligent construction platform for facade operations. The standard sections of the integrated platform are used as the common tracks of the on-site construction elevator, and a column foundation and foundation reinforcement are shared. The overall installation volume of the construction elevator equipment is reduced, the number of columns is reduced, the verticality is controlled by the integrated platform, the operating efficiency is increased, and the safety is more reliable.

[0004] To achieve the above object, the technical solution of the present invention is as follows: The common track method of construction elevators and the integrated intelligent construction platform for facade operations uses the standard sections of the integrated platform as the common track for on-site construction elevators, while sharing a column foundation and foundation reinforcement to achieve multifunctional integration of intelligent construction equipment.

[0005] The common rail installation method of the construction elevator and the facade operation intelligent construction integrated platform includes the following steps: S1 track foundation construction During foundation construction, screw rods are embedded in advance, and after acceptance, concrete is poured and the foundation surface is leveled; S2 construction elevator base and standard section installation After the foundation concrete reaches the specified strength, first fix the base to the foundation surface through embedded screws; Connect the standard sections to form a guide rail frame; Install construction elevator buffer springs; S3 integrated platform installation According to the installation sequence, the installation of the bracket system, the drive system and the steel platform system are gradually carried out. The standard section of the construction elevator is used as the support system, and the external drive sleeve is installed. The motor gear of the drive system is meshed with the standard section rack. The motor rotates to drive the integrated platform or the construction elevator to run, and the two are set on the same track; S4 construction elevator common rail installation The loose installation method is adopted. After the drive system is installed on the standard section, the construction elevator car part and the drive part are assembled.

[0006] As a supplement to the present invention, the screw rods described in step S1 are pre-buried, and their positions are set using a total station.

[0007] As a supplement to the present invention, the guide rail frame described in step S2 is 650mm×650mm×1508mm, the rack module is 8mm, the standard section wall thickness is 6mm, and M24-8.8 grade bolts are used from bottom to top to connect the standard sections to form a guide rail frame, which is connected to the foundation embedded parts through the chassis and fixed to the building with the wall frame to serve as the guide rail for the construction elevator to run up and down.

[0008] As a supplement to the present invention, the construction elevator described in step S2 shares a base with the integrated intelligent construction platform for facade operations, and has the same specifications and models. As a supplement to the present invention, the specific steps of step S3 are as follows: After the S31 basement roof reaches the required strength, the cradle is laid out according to the design drawings. First, the horizontality of the cradle installation is ensured, and second, the overall elevation of the cradle is raised to ensure that protection can be carried out after installation. After the cradle is erected, the cradle is assembled in situ and constructed upwards synchronously with the main structure. Finally, the main structure and the cradle system meet at the Nth floor. At this time, the overall installation of the building machine can be completed, and the cradle is connected to the steel platform of the building machine. After the lifting conditions are met, it is lifted to provide protection for the structure of the N+1th floor; S32 As the assembly height of the bracket increases, the standard section of the column is inserted for heightening and installation. When the concrete strength of the first floor of the building reaches 75%, the first wall-attached rod is installed; S33 Step 2 After the bracket is installed, the drive system installation begins. The drive system is inserted into the installed standard section. Each drive system is hoisted twice. The number of motors is 9 to 12. Each drive system is equipped with 2 anti-drop devices. The drive motor drives the drive system to run on the standard section rack to realize the overall operation of the integrated platform. The anti-drop device is arranged on the drive plate, and the pinion is engaged with the rack to prevent the drive sleeve from stalling and falling. S34 After the main structure is constructed to the third floor and the supporting system has at least two attached walls, the Bailey frame is inserted for hoisting. The Bailey frame is divided into sections and numbered, and assembled on the ground according to the numbering sequence. The single-piece Bailey frame is connected by pins to form a whole Bailey frame for hoisting. After the hoisting is completed, the anti-top limit device is connected to the uppermost part of the drive frame, and the designed signal transmission device is overlapped with the column rack track. When the signal transmission device exceeds the rack, the signal is fed back to each motor to stop running, thereby meeting the anti-top requirement of the power system.

[0009] As a supplement to the present invention, the specific steps of step S4 are as follows: S41 After the integrated platform is installed, install the left fence, left rear fence, right rear fence, right fence, power cabinet frame, front fence, door support of the outer cage in sequence, and adjust the verticality of each fence; S42 Use lifting equipment to lift the cage into place, install cage top protection fence, upper and lower channel detection, transmission trolley and cable bracket; S43 Connect the power cord and check whether the indicator light, circuit, cage door lock and outer cage door lock contact iron are normal; S44 lower limit stopper and limit switch stopper installation; S45 upper limit stopper and limit switch stopper are installed.

[0010] As a supplement to the present invention, the specific steps of step S44 are as follows: S441 Raise the cage to above the lower limit stop iron installation position and cut off the power supply; fix the cage to the guide rail frame with a wire rope or maintenance pipe clamp to prevent it from sliding down; S442 Install the lower limit stopper and the limit switch stopper, power on the cage, and untie the wire rope or pipe clamp; S443 Start the construction elevator to the horizontal position of the outer cage threshold, confirm whether the lower limit stopper and the limit switch stopper are working normally, and ensure that the limit stopper is activated before hitting the spring buffer.

[0011] As a supplement to the present invention, the specific steps of step S45 are as follows: S451 raises the cage to the N-1 floor position at the bottom of the integrated platform and determines the position where the upper limit touches the iron and the limit switch touches the iron; S452 Lower the cage to below the installation position of the upper limit stopper and the limit switch stopper, and install the upper limit stopper and the limit switch stopper. There needs to be an overtravel distance of 150mm between the two during installation. After S453 is installed, start the lift to the point where the upper limit switch touches iron and the limit switch touches iron, and confirm whether the upper limit switch and the limit switch are working normally; S454 Every time the integrated platform is lifted, the upper limit switch must be repositioned and the upper limit switch or limit switch must be checked to see if it is normal.

[0012] The beneficial effects of the present invention are: (1) Compared with the traditional construction elevator installation, the common rail elevator described in the present invention not only ensures the operation of intelligent equipment, but also realizes the common rail integration of the elevator, which is conducive to the development and gradual realization of the functional integration of intelligent construction equipment.

[0013] (2) Improve operational efficiency. By sharing the same track with intelligent construction equipment, there is no need for separate wall support and standard section hoisting, which greatly reduces construction costs and downtime. At the same time, it reduces on-site vertical adjustment and measurement. All pre-processing steps are completed uniformly when the intelligent construction equipment is lifted, improving the operating efficiency of the construction elevator.

[0014] (3) Safety and environmental protection. By setting up the common rail with the integrated platform, the requirements of layer-by-layer attachment of the integrated platform are referred to, and the verticality measurement and setting of each layer are required, which greatly guarantees the operation safety of the common rail elevator.

[0015] (4) Reduce project costs. By sharing the same track with the integrated platform, the construction elevator foundation and standard section do not need to be set up separately, and the workers do not need to install the wall-mounted rods separately, thereby reducing project costs.

[0016] (5) High installation accuracy. When the foundation of the integrated platform is manufactured, the screws are pre-buried in advance to ensure the installation accuracy of the construction elevator. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] As shown in the figure, the common track method for construction elevators and the integrated intelligent construction platform for facade operations described in the present invention uses the standard sections of the integrated platform as the common tracks for on-site construction elevators, and shares a column foundation and foundation reinforcement, thereby realizing the multifunctional integration of intelligent construction equipment, reducing the overall installation volume of construction elevator equipment, reducing the number of columns, controlling the verticality of the integrated platform, increasing operating efficiency, and making safety more reliable.

[0024] The specific construction process is as follows: 1. Construction Preparation 1 According to the construction site conditions, take full account of the common rail position of the construction elevator and the integrated platform column, formulate a construction plan, and conduct safety technical briefings and pre-job training education for all construction personnel; 2 Carry out the construction elevator foundation production and component installation in advance, and provide a working surface to ensure that the construction elevator can be installed immediately after the integrated platform is installed.

[0025] 2. Common rail design of guide rail frame 1 According to the relevant data provided by the construction elevator manufacturer, design and calculate the stress, strength and deformation of the whole and each component of the working platform during the ascending and descending stages; 2 The guide rail frame (standard section) is 650mm×650mm×1508mm, the rack module is 8mm, and the wall thickness of the standard section is 6mm. Use M24-8.8 grade bolts from bottom to top to connect the standard sections to form a guide rail frame, which is connected to the foundation embedded parts through the chassis and fixed to the building with the wall frame to serve as the guide rail for the construction elevator to run up and down.

[0026] 3. Foundation steel bar binding 1 According to the design drawings and the dimensions of the construction elevator foundation, carry out targeted reinforcement design to ensure that the bearing capacity meets the design requirements.

[0027] 4. Pre-embedded foundation screw According to the requirements of the drawings, 8.8-grade / M24 / 780mm long screws are selected. According to the point requirements of the drawings, the screw points are placed using a total station, and then the placed screw points are welded using a welding machine to effectively avoid the deviation of the screw points. It is required to use the total station at the same point to place all the screw points at one time. After the placement is completed, 10% of the sample points are taken for review the next day.

[0028] 5. Foundation formwork support and concrete pouring According to the design drawings, the foundation formwork is set up. After the foundation reinforcement is accepted, wooden formwork is used for construction. After the four sides of the formwork are set up, they are reinforced with wooden planks to prevent the formwork from shifting due to plastering and causing the foundation pouring to shift. During pouring, a special person is assigned to finish the surface to ensure the foundation is level.

[0029] 6. Installation of construction elevator base and standard sections 1 After the foundation concrete reaches the required strength, the base is installed (the construction elevator and the integrated intelligent construction platform for facade operations share the same base, with the same specifications and models). The base is fixed to the foundation surface through embedded screws. The column base is leveled using a leveler. Steel washers (specification size: 50×50×2mm) are added to the base to meet the base level control. After the base is leveled, the standard section installation is started. At the same time, steel washers are used. The double nut combination locks the base to the embedded screw; 2 When installing the standard section, it is necessary to distinguish between the conventional standard section and the reinforced standard section used in the integrated platform. The common rail of the construction elevator uses a 6mm thick standard section. When installing the standard section, use M24-8.8 grade bolts from bottom to top to connect the standard sections to form a guide rail frame. For the installed standard section, measure and adjust the verticality, and check the verticality of each riser of the guide rail in the adjacent direction ≤1 / 1500; 3 Install the construction elevator buffer spring on the buffer spring seat, and then place the buffer spring.

[0030] 7. Integrated platform installation According to the installation sequence, the installation of the bracket system, the drive system and the steel platform system shall be carried out step by step. When installing each system, it is necessary to inspect and accept the installation of each system in accordance with the requirements of the construction plan. It can be put into use only after passing the inspection and acceptance.

[0031] 1 After the basement roof reaches a certain strength, the cradle is laid out according to the design drawings. The first is to ensure the horizontality of the cradle installation, and the second is to raise the overall elevation of the cradle to ensure that protection can be carried out after installation. After the cradle is erected, the cradle is assembled in situ and constructed upwards synchronously with the main structure, completely eliminating the impact of the frame installation on the protection during the main construction process. Finally, the main structure and the cradle system intersect on the fifth floor. At this time, the overall installation of the building machine can be completed, and the cradle is connected to the steel platform of the building machine. After the conditions for jacking are met, it is lifted to provide protection for the sixth-floor structure. 2 As the assembly height of the bracket increases, the standard section of the column is inserted for heightening and installation. When the concrete strength of the first floor of the building reaches 75%, the first wall-attached rod can be installed.

[0032] 3 After the second step of the bracket installation, the drive system installation begins. The drive system is inserted into the installed standard section (verticality has been checked). Each drive system is hoisted twice for a total of 8 meters. Each drive system is reviewed according to the actual force on site. The number of motors is 9 to 12, and each drive system is equipped with 2 anti-drop devices. The drive motor drives the drive system to run on the standard section rack to realize the overall operation of the integrated platform. The anti-drop device is arranged on the drive plate, and the engagement of the pinion and the rack can effectively prevent the drive frame from stalling and falling.

[0033] 4 After the main structure is constructed to the third floor and the support system has at least two attached walls, the Bailey frame is inserted for hoisting. The Bailey frame is divided into sections and numbered. It is assembled on the ground according to the numbering sequence. The single-piece Bailey frame is connected by pins to form a whole Bailey frame for hoisting. After the hoisting is completed, the anti-collision limit device is connected to the top of the drive frame, and the designed signal transmission device is overlapped with the column rack track. When the signal transmission device exceeds the rack, the signal is fed back to each motor to stop running, meeting the anti-collision requirements of the power system.

[0034] 8. Common rail installation of construction elevator 1 After the integrated platform is installed, install the left fence of the outer cage, the left rear fence (inspection door frame, door), the right rear fence, the right fence, the power cabinet frame, the front fence, install the door support, and adjust the verticality of each fence.

[0035] 2 Use lifting equipment to lift the cage into place, install the cage top protective fence, upper and lower channel detection, transmission trolley and cable bracket.

[0036] 3 Connect the wires and turn on the power, and check whether the indicator lights, circuits, cage door locks and outer cage door locks are functioning normally.

[0037] 4 Installation of lower limit stopper and limit switch stopper (1) Raise the cage to above the lower limit stop iron installation position and cut off the power supply; fix the cage to the guide rail frame with a wire rope or maintenance pipe clamp to prevent it from sliding down; (2) Install the lower limit stopper and the limit switch stopper, power on the cage, and untie the wire rope or pipe clamp; (3) Start the construction elevator to the horizontal position of the outer cage threshold, confirm whether the lower limit stopper and the limit switch stopper are working normally, and ensure that the limit stopper is activated before the spring buffer is touched.

[0038] 5. Installation of upper limit stopper and limit switch stopper (1) Raise the cage (top of the transmission mechanism) to the N-1 floor position at the bottom of the integrated platform, and determine the position of the upper limit iron contact and the limit switch iron contact; (2) Lower the cage to below the installation position of the upper limit stopper and the limit switch stopper, and install the upper limit stopper and the limit switch stopper. There needs to be an overtravel distance of 150 mm between the two during installation; (3) After installation, start the lift until the upper limit switch touches iron and the limit switch touches iron, and confirm whether the upper limit switch and the limit switch are working normally.

[0039] (4) Each time the integrated platform is lifted, the upper limit switch must be repositioned and the upper limit switch or limit switch must be checked to see if it is normal.

[0040] The construction elevator and the integrated platform described in the present invention have the same support system design, both use the standard section of the construction elevator as the support system, and the principle is that the motor gear is meshed with the standard section rack, and the integrated platform or the construction elevator is driven by the rotation of the motor, so the two can be set on a common track.

[0041] The construction elevator described in the present invention needs to be installed on site after the installation of the integrated platform is completed. The overall installation form is different from the installation of the construction elevator by inserting it into the standard section. It adopts a bulk installation method. After the drive system is installed on the standard section, the construction elevator car part and the drive part are assembled to ensure that the two are smoothly integrated together.

[0042] In order to accurately install the construction elevator, the position of the construction elevator and the integrated platform when they are integrated must be strictly considered during the production of the foundation of the integrated platform, while avoiding interference with the main structure. The screws must be embedded in advance during foundation production, and the screw positions must be accurately placed using a total station. The positions of each screw must be reviewed according to the plan, and after acceptance, concrete is poured and the foundation surface is leveled to ensure the horizontality of the base installation.

[0043] Economic Benefit Analysis Take the integrated intelligent construction platform for facade operations and the common rail construction of construction elevators for a new resettlement housing project on a certain plot as an example to conduct a benefit analysis; (1) Traditional elevator construction method It takes about 2 man-days to make the foundation alone, about 30 man-days to install the standard section, 30 man-days to install the wall, and 24 man-days to maintain and measure the daily work. The average labor cost is 500 yuan / (person-day); Labor cost: 86×500=43,000 yuan Standard section rental fee: 60×45×6=16,200 yuan Attached wall rental fee: 10×45×6=2,700 yuan Elevator rental fee: 6×5=300,000 yuan Total cost = 361,900 yuan (2) Integrated platform construction elevator common rail No need to make a foundation separately, install standard sections, install attached walls separately, or maintain verticality. Elevator rental fee: 6×5=300,000 yuan Total cost = 300,000 yuan Table 10.1 Economic Benefit Analysis Table Fee Type Cost of this method (ten thousand yuan) Cost of traditional method (10,000 yuan) Amount saved (10,000 yuan) Labor cost 0 4.3 4.3 Material cost 0 1.89 1.89 Machinery and equipment fee 30 30 0 total 30 36.19 6.19 In summary, the economic benefit achieved by adopting this method is 61,900 yuan, and the cost savings are 6.19 / 36.19=17.10%, which has good economic benefits.

[0044] The method of sharing tracks between construction elevators and integrated work platform construction elevators. The cost estimation is only for a single construction elevator. If the overall investment of a single project or the overall investment of a single area project is considered, the economic benefits generated will be greatly increased.
