Description

Technical Field

[0001] The invention relates to the field of building construction, and more specifically to an integrated platform for caisson construction equipment. Background Art

[0002] At present, the traditional method of bridge anchor caisson construction is mainly a combination of walking tower crane and flip form + gantry crane. The caisson concrete structure is constructed using the flip form technology. During the construction of each section of the caisson, the operator stands on the cantilever construction platform to tie, connect and install the embedded parts of the vertical steel bars. After the hidden acceptance of the steel bar binding, the caisson structure formwork is installed and reinforced by manual cooperation with the tower crane, and then the concrete is poured by a car pump. After the concrete reaches the strength, the tower crane is used to flip the formwork and the cantilever construction platform to the previous wall section, completing the construction of a structural section.

[0003] In order to move the mud pump pipe in the caisson, a gantry crane needs to be installed on the top of each caisson grid. After the construction of each structural section is completed, the gantry crane leg track is installed on the top of the caisson concrete structure. The gantry crane can slide horizontally on the travel track. The sliding of the gantry crane drives the vertical mud suction pump pipe to pump out the mud in the caisson. The horizontal mud pump pipe is placed on the cantilever construction platform.

[0004] Each time the caisson sinks and the caisson concrete structure is constructed, the gantry crane on the top of the caisson structure needs to be moved outside the safe range of the caisson. After the caisson sinks into place or the structure construction is completed, the gantry crane is moved back to the top of the caisson concrete structure. Due to the influence of site conditions, the number of gantry cranes, the installation and disassembly method of the driving track, etc., the installation and disassembly time of the gantry crane is one month each time, which greatly increases the overall construction period of the caisson. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an integrated platform for caisson construction equipment, which can effectively improve the work efficiency of caisson construction, has strong turnover, and saves the overall construction period.

[0006] The technical solution adopted by the present invention to solve its technical problems is: construct an integrated platform for caisson construction equipment, including a support column, a steel platform, a lower hanger, a hanger, a one-way self-locking clamp, a shoulder pole, a hook, a climbing rod, a steel template and a hydraulic cylinder, the hanger is fixed on the caisson concrete structure by attachment, the one-way self-locking clamp is connected to the hanger through a shoulder pole, the support column is connected to the hanger, the top of the support column is fixedly connected to the steel platform, the support column is provided with a window hole for climbing in coordination with the hook of the hanger, the hydraulic cylinder is installed on the bottom crossbeam of the support column, the climbing rod is arranged on the bottom crossbeam of the support column and connected with the one-way self-locking clamp on the hanger, the lower hanger is hung on the bottom of the steel platform through a suspension rod, and the steel template is hung on the lower part of the steel platform through a chain; When the hydraulic cylinder is extended, it pushes the support column upward, and the support column disengages the hook claw. The beam transfers the downward force it receives to the climbing rod, and then to the shoulder pole and the bracket, and finally to the concrete structure of the caisson. After the hydraulic cylinder pushes the support column upward through a stroke, the hook claw supports the support column again, and the hydraulic cylinder is retracted to achieve a rise of the crossbeam and the climbing rod. The above steps are repeated, and the hydraulic cylinder is raised by multiple small strokes to achieve the jacking of the support column to complete the predetermined total stroke.

[0007] In the above scheme, a rotatable hook is provided on the hanging seat, and a plurality of blocks cooperating with the hook are provided on the supporting column, and the hook is stuck under the block to prevent the supporting column from falling; when the supporting column is lifted, the block above the hook is disengaged from it, and when the block below the hook moves upward to contact with the hook, the hook rotates under the action of the block, and when the block moves up to above the hook, the hook returns to its initial position, and the hook blocks the block above.

[0008] The above scheme also includes a winch, which is suspended under the steel platform through a truss.

[0009] The above scheme also includes a material placing machine, which is placed on a sliding support on the top of the steel platform.

[0010] In the above solution, the hanging bracket is attached to the caisson concrete structure through a rotatable screw.

[0011] In the above solution, the top of the supporting column is connected to the steel platform by high-strength bolts.

[0012] In the above scheme, a walkway plate and a flap are provided on the lower hanging frame.

[0013] In the above solution, the steel platform is composed of Bailey plates.

[0014] The integrated platform for caisson construction equipment of the present invention has the following beneficial effects: 1. The present invention uses the caisson concrete structure as an attachment fulcrum. The overall upward movement of the platform drives the vertical steel formwork to move upward, without the need for tower cranes and other equipment, avoiding on-site disassembly and assembly operations, saving labor and improving the appearance quality of the concrete; the steel formwork system is hung at the bottom of the steel platform by chains, greatly reducing on-site manual installation and disassembly operations; 2. The present invention adopts a movable truss and a winch to completely replace the gantry crane to translate the mud pump and the mud discharge pipe in the caisson, thereby avoiding the influence of the gantry crane track on the caisson concrete structure construction and greatly shortening the gantry crane installation and disassembly period; 3. The top of the present invention is a truss platform connected by longitudinal and transverse Bailey plates, which not only enhances the overall safety of the structure, but also provides a valuable aerial work platform and a platform for the integration of the crane system, the rack system, the hanging of the steel formwork and the placing machine; 4. The present invention matches the vertical steel bar → formwork → concrete → bottom mud removal process, meets the 7-day / layer progress of the caisson concrete structure construction, and provides convenience for the caisson structure section operation without interfering with the structure construction; 5. The top steel platform of the present invention can adopt light 321 type Bailey plate, which improves the overall safety of the device and provides a rare equipment integration site for high-altitude operations. The setting of hydraulic remote control placing machine and small lifting equipment can effectively serve the on-site construction and improve the on-site work efficiency; 6. The present invention places the horizontal mud pump pipe on the hanger, and the horizontal mud pump pipe rises together with the platform jacking, which reduces the installation and removal of the mud pump pipe and saves construction time.

DETAILED DESCRIPTION

[0016] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0017] like Figure 1-8, the integrated platform for caisson construction equipment of the present invention includes a supporting column 1, a rotatable screw rod 2, a steel platform 3, a lower hanger 4, a hanger 5, a one-way self-locking clamp 6, a shoulder pole 7, a hook 8, a climbing pole 9, a steel formwork 10, a hydraulic cylinder 11, a placing machine 13, a truss 16 and a winch 17.

[0018] like Figure 1 As shown, when the caisson construction equipment integrated platform is lifted, it is supported by three sets of hangers 5, the middle hanger is used as the main load-bearing component of the vertical force, and the upper and lower hangers 5 mainly bear the horizontal force to prevent the column from tilting; the hanger 5 is connected to the caisson concrete structure through a traversable bolt 2; the hook 8 is combined with the hanger 5 through a pin, and the hook 8 supports the supporting column through the window baffle 14 provided by the structure of the supporting column 1 itself, the shoulder pole 7 is connected to the hanger 5 through a pin, and the one-way self-locking clamp 6 is installed on the shoulder pole to clamp the upper part of the climbing rod 9 and limit the climbing rod 9 to move only upward, the lower part of the climbing rod 9 is connected to the crossbeam 12 built into the cavity of the supporting column 1 through a pin, the lower part of the crossbeam 12 is connected to the lower part of the hydraulic cylinder 11 built into the cavity of the supporting column, and the upper part of the hydraulic cylinder 11 is connected to the stiffening plate 22 inside the supporting column 1. The upper end of the supporting column 1 is fixedly connected to the steel platform 3, and the steel platform 3 is suspended by the suspension rod 18 to set the lower hanger 4. The steel template 10 is suspended at the bottom of the steel platform 3 by a chain 19 .

[0019] The working principle of the present invention is as follows: Through the extension of the hydraulic cylinder 11, the support column 1 is pushed back to rise, and the support column 1 is disengaged from the hook 8. At this time, the cross beam 12 transmits the downward force it receives to the climbing rod 9, and then to the shoulder pole 7 and the hanger 5, and finally transmits the force to the caisson concrete structure. After the hydraulic cylinder 11 drives the support column 1 to rise by one stroke, the hook 8 supports the support column 1 again. Through the retraction of the hydraulic cylinder 11, the climbing rod 9 and the cross beam 12 are raised by one stroke. Finally, the one-way self-locking clamp 6 of the shoulder pole 7 locks the climbing rod 9 again, and the above steps are repeated. Through the hydraulic cylinder 11, the small strokes are raised multiple times to realize the jacking of the support column 1 to complete the predetermined total stroke. In the process, the sensor 15 installed in the support column 1 is used to monitor and feedback the stroke of the hydraulic cylinder 11 and the action of the hook 8 supporting the support column 1. The lifting of the support column 1 drives the overall lifting of the steel platform 3, and the lifting of the steel platform 3 can also drive the steel template 10, the placing machine 13, the lower hanger 4, the truss 16 and the winch 17 to lift.

[0020] like Figure 1 and Figure 6 As shown, the hydraulic cylinder 11 is equipped with a displacement sensor 15 and a matching power pump station 23. The displacement sensor 15 is used to judge and feedback the extension length of the hydraulic cylinder. The power pump station 23 is used to provide power for the extension of the hydraulic cylinder 11, thereby realizing automatic lifting of the hydraulic cylinder 11 under the control of the electronic control system.

[0021] The lifting and supporting system of the present invention drives the steel platform to rise, thereby realizing the lifting of the integrated platform of the caisson construction equipment. The present invention can be widely used in caisson construction and the lifting or lifting and supporting structure of similar liftable systems, and also belongs to the protection scope of the present invention.

[0022] In the above embodiment, the support column 1 includes high-strength bolts, steel, window baffles 14, horizontal stiffening plates 22, steel plates and connecting bolts. A single support column 1 has a bearing capacity of 50 tons, the window baffles 14 can provide a bite point for the support of the hook 8, and the internal cavity can provide sufficient protection for the hydraulic cylinder 11 and the sensor 15.

[0023] In the above embodiment, the steel platform 3 is composed of a single 1.5m high and 3m long 321-type standard Bailey sheet and a non-standard Bailey sheet with a length other than 3m, which are spliced ​​horizontally and vertically. The arrangement of the Bailey sheet is specifically designed according to the plane structure of the caisson, and is adopted after overall modeling and calculation by Midas calculation software. The top surface of the steel platform 3 can be used for pedestrians and stacking of some materials, and a placing machine 13 can be installed. The lower part can be installed with a truss 16 and a winch 17. The bottom surface of the steel platform 3 is suspended by a hanger 18 to set up a rack system to assist in the construction of the working layer.

[0024] In the above embodiment, a facade protection net 20 is provided on the outer facade of the steel platform 3, and the facade protection net 20 is arranged on both sides of the Bailey plate of the steel platform at the top of the steel platform. Its purpose is to meet the necessary protective measures set up for on-site safe operations. The integrated design with the caisson construction equipment integrated platform further highlights the safety characteristics of the platform.

[0025] In the above embodiment, the lower bracket 4 is suspended at the bottom of the steel platform by the suspension rod 18, and the bracket system includes the suspension rod 18, a small cross bar, a patterned steel plate walkway plate, a patterned steel plate flap and other components. The components are assembled by welding bolts, pins and flat irons, the number of walkways is 7 or so, and the single-step height is 2m or more. The lower bracket 4 acts as a structural construction platform for the caisson steel formwork 10 by the top walkway, the middle area of ​​the lower bracket 4 acts as a channel for placing the air supply pipe and the exhaust pipe, the middle walkway of the lower bracket 4 acts as a cleaning and maintenance platform on the structural facade after demoulding, and the bottom walkway of the lower bracket 4 acts as a construction platform for the revolving screw rods for removing the hanger.

[0026] In the above embodiment, a one-way self-locking clamp 6 is installed on the shoulder pole 7, and the self-locking clamp 6 can clamp the upper part of the climbing pole 9, which is enough to offset the vertical downward pulling force of the supporting column 1 during the rising process, thereby limiting the climbing pole 9 to only go upward, and also has the function of a fall arrester.

[0027] In the above embodiment, the hook claw 8 is made of steel plate. When the supporting column 1 rises, the hook claw 8 can rotate by the upward friction force of the supporting column 1, thereby not hindering the rising of the supporting column 1. However, when the supporting column 1 descends and encounters the window pane baffle 14, the hook claw 8 will automatically rotate under its own gravity and support the window pane baffle 14 of the supporting column 1.

[0028] In the above embodiment, the climbing pole 9 is made of solid 45# round steel, which can support the vertical force exerted on the entire supporting column 1 and is more advantageous for controlling the verticality of the supporting column 1 during its ascent, and rises with the recovery of the hydraulic cylinder 11.

[0029] In the above embodiment, the hydraulic cylinder 11 is a cavity built into the supporting column 1. The bidirectional hydraulic pump is driven by the speed regulating motor, and the bidirectional hydraulic pump directly drives the hydraulic cylinder to extend, thereby pushing the supporting column 1 to rise. The multiple hydraulic cylinders 11 are synchronously dynamically adjusted and monitored through oil pressure and real-time displacement, so as to achieve synchronous extension of the multiple hydraulic cylinders 11, thereby achieving synchronous rise of the multiple supporting columns 1.

[0030] In the above embodiment, the sensor 15 is installed in the cavity inside the support column 1, and is closely combined with each hook window baffle 14 of the support column 1, using a photoelectric sensor. The sensor 15 can monitor the action of the hook and feedback the load-bearing state, thereby monitoring and feedback the jacking process.

[0031] In the above embodiment, the template system includes a chain 19, a connector 21 and a steel template 10. The steel template 10 is connected to the steel platform 3 through the connector 21. The steel template 10 is installed and removed as a whole when in use. After the steel template 10 is demolded by the tension screw, it is moved backward as a whole to disengage from the vertical structure of the caisson, and the caisson construction equipment integrated platform is moved forward to close the mold after it is self-lifted for a section, thus realizing the integrated design of the template system and the caisson construction equipment integrated platform.

[0032] In the above embodiment, the concrete placing machine 13 is placed on the top of the steel platform 3. The concrete placing machine 13 in this embodiment is a remote control concrete placing machine, which includes a fixed base, a hydraulic turntable, and an adjustable concrete placing arm. The complete set of equipment is usually supplied by a professional manufacturer. The base of the concrete placing machine 13 is fixed on the top surface of the steel platform 3. The pump pipe only needs to be connected to the bottom of the concrete placing machine 13 to achieve concrete pouring and distribution in a large range in the caisson, thereby improving the convenience of concrete pouring and operation efficiency.

[0033] In the above embodiment, the truss 16 and the winch 17 are arranged at the bottom of the steel platform 3. The winch 17 can move horizontally on the truss 16, and can lift and transport the mud pump within the caisson. At the same time, it can also facilitate the lifting and material transportation of small weight operations in the working area, thereby improving the level of on-site assembly operations.

[0034] In the above embodiment, compared with the traditional mold turning device, the lower hanger 4 of the present invention can cover a higher height, the bottom surface of the steel platform 3 is integrated with the hanging steel formwork 10, the top surface of the steel platform 3 is integrated with the fabricator, and the longitudinal and transverse structures of the steel platform 3 tie the outer ring frame together to enhance the overall safety of the device, which has obvious advantages over the traditional mold turning device.

[0035] In the above embodiment, the suspended steel formwork 10 is first disconnected from the caisson concrete structure before the device is lifted, and then the steel formwork 10 is carried up to a construction section height by the power of the hydraulic cylinder 11, and the vertical reinforcement of the previous section is tied. After the vertical reinforcement of the previous section is tied, the steel formwork 10 is closed, and finally the concrete is poured using the placing boom 13 to complete a standard construction process. The construction period of a standard layer is 15 days.

[0036] The implementation process is shown in the attached Figure 8a-8i The present invention sets a low-position wall-attached fulcrum at the lower part of the working layer to provide "steel cover" protection around and on the top of the working surface, and integrates construction auxiliary equipment and frames with it to achieve the maximum auxiliary effect on on-site services. The standard construction process is 15 days / layer. For details, see the flow chart. The following only describes the key working procedures of the building construction equipment operation.

[0037] Step 1: The concrete pouring of the vertical structure of the n-layer caisson is completed to the initial state.

[0038] Step 2: After the n-layer caisson vertical structure steel formwork 10 reaches the dismantling conditions, the reinforcing screw rods and back ribs are removed to separate the n-layer caisson vertical structure steel formwork 10 from the structure.

[0039] Step 3: Flip up the horizontal protective flap of the bracket system, check whether the lower bracket 4 and the steel formwork 10 are detached from the structure, and then control the hydraulic device through the control room on the top surface of the steel platform 3 to lift the supporting column 1 together with the entire caisson construction equipment integrated platform by one structural section.

[0040] Step 4: Tie up the n+1 layers of vertical reinforcements, and inspect the vertical reinforcements after tying is completed.

[0041] Step 5: Support the caisson steel formwork 10 and close the mold for the n+1 layer of vertical reinforcement. The area where the formwork 10 is hung only needs to push the formwork 10 toward the wall and clamp it to the wall.

[0042] Step 6: Pour the n+1 layer of vertical concrete.

[0043] Step 7, return to the first step, enter the initial state, and repeat the construction operation over and over again.

[0044] During the structural construction process, the crane system at the bottom of the steel platform mobilizes the mud pump to discharge the mud in the caisson.

[0045] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
