Description

Technical Field

[0001] This invention relates to the field of civil engineering construction technology, and more specifically, to an installation device and method for prefabricated steel truss floor decking. Background Technology

[0002] In recent years, the application of steel structures has seen significant development, with both quantity and quality far exceeding previous levels. Steel structure buildings have experienced rapid growth in economically developed regions. Prefabricated steel truss floor decks are an important type of floor deck in civil engineering construction and are widely used in steel structure buildings. Prefabricated steel truss floor decks consist of steel trusses and steel plates, with the steel trusses fixed to the upper layer of the steel plates. The steel truss floor deck formwork system integrates the steel reinforcement in the concrete floor slab with the construction formwork, forming a load-bearing component capable of withstanding the self-weight of wet concrete and construction loads during the construction phase. This component can also be used as lateral support for steel beams during construction. During the service phase, the steel truss and concrete work together to bear the service load. Steel truss floor decks can meet the requirements of rapid construction in steel structure buildings, providing a working platform for construction workers in a short time, increasing the rigidity of the floor slab while saving on the amount of steel reinforcement and concrete used. During construction, the prefabricated steel truss floor decks are first laid one by one on the already erected steel beams. Currently, this laying operation is mainly done manually. The floor decks are lifted onto the steel beams by a crane, and then the laying and welding are manually aligned. Since the workers are working at height for a long time, there are significant construction safety hazards. In addition, manual laying has the disadvantages of low efficiency and high labor requirements. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an installation device and method for prefabricated steel truss floor decking. The paving trolley of this device can be adapted to be installed on building steel beams and can travel along the length of the steel beams. During the travel, it can realize automated floor decking laying. This device is also designed with a supplementary trolley, which can replenish floor decking to the paving trolley in real time to meet the needs of continuous paving.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An installation device for prefabricated steel truss floor decking includes a paving trolley and a crane chassis. The paving trolley has a first storage area where floor decking to be paved is stacked. The crane chassis is mounted on the paving trolley platform, and a paving crane is movably mounted on the crane chassis. A floor decking lifting device is installed on the paving crane, which can grab the floor decking. The paving trolley has a paving side, and the paving crane can move in the paving side direction. The floor decking can be lifted onto a steel beam in the paving side direction by the floor decking lifting device.

[0006] Furthermore, the crane chassis includes a transmission frame, a crane drive assembly, and a crane base. The transmission frame is fixedly installed on the paving trolley platform, the crane drive assembly is installed inside the transmission frame, the crane base is drivenly connected to the crane drive assembly, and the paving crane is fixedly installed on the crane base.

[0007] Furthermore, the crane drive assembly includes a transmission screw, guide rods, and a motor. The transmission screw is rotatably mounted within the transmission frame. The two guide rods are respectively mounted on both sides of the transmission screw and are fixedly installed. The output end of the motor is connected to the transmission screw. The crane base is mounted on the two guide rods and is threadedly connected to the transmission screw.

[0008] Furthermore, the paving crane includes a column, a crossbeam, and a crane beam. The bottom of the column is fixedly connected to the crane base, and the crossbeam is fixedly connected to the top of the column. A guide rail is installed on the crossbeam, and one end of the crane beam is movably mounted on the guide rail. A first push cylinder is installed on the crossbeam, and the piston rod end of the first push cylinder is connected to the crane beam. When the piston rod of the first push cylinder extends, the crane beam can move towards the paving side. Several second push cylinders are installed on the crane beam, and the second push cylinders are installed vertically downward. The floor slab hanger is connected to the piston rod end of the second push cylinder.

[0009] Furthermore, a stroke control bolt and a linkage switch are installed on the transmission frame. Both the stroke control bolt and the linkage switch are installed on the paving side. The stroke control bolt and the linkage switch block the movement path of the crane base. The linkage switch circuit is connected to the first push cylinder. When the crane base contacts the stroke control bolt, the linkage switch is triggered by the pressure of the crane base, and the piston rod of the first push cylinder extends in linkage.

[0010] Furthermore, the floor slab hoist includes a lifting platform, two electromagnets are installed below the lifting platform, and two symmetrically arranged welding assemblies are installed on the lifting platform. Each welding assembly includes a third push cylinder and a lifting linkage plate. Several third push cylinders are arranged in a row and installed vertically downward on the lifting platform. The lifting linkage plate is connected to the piston rod end of the third push cylinder, and several welding guns are installed on the bottom surface of the lifting linkage plate.

[0011] Furthermore, the paving trolley is equipped with a supplementary trolley, which has a floor slab replenishment port. The supplementary trolley can move along the same trajectory as the paving trolley and can dock with the floor slab replenishment port of the paving trolley. The supplementary trolley has a second storage area where the floor slabs to be replenished are stacked. The supplementary trolley is equipped with a slab discharge conveyor belt located in the second storage area. The paving trolley is equipped with an infeed conveyor belt that starts from the floor slab replenishment port and extends into the first storage area. Correction components are installed on both sides of the first storage area of ​​the paving trolley and both sides of the second storage area of ​​the supplementary trolley.

[0012] Furthermore, the first storage area of ​​the paving trolley is provided with an opening, which faces the direction of the floor slab replenishment opening. Two opening and closing stops are symmetrically installed at the opening position of the first storage area, and the opening and closing stops can control the opening and closing position of the first storage area opening.

[0013] Furthermore, the opening and closing stop includes a stop box and a linkage box. The stop box is fixedly installed on the platform of the paving trolley, and the linkage box is installed on the paving trolley body. A first piston is installed inside the stop box. One side of the first piston is set as a first oil chamber, and a spring is installed on the other side of the first piston. Two stop rods are connected to the first piston. The stop rods are installed on the side of the first oil chamber. The first oil chamber extends through to the outside of the stop box. A second piston is installed inside the linkage box. A second oil chamber is set on one side of the second piston, and a piston connecting rod is installed on the other side of the second piston. The piston connecting rod is fixedly connected to the second piston. The first oil chamber and the second oil chamber are connected by pipelines. Two docking heads are connected to the supplementary trolley. The docking heads are set one-to-one with the linkage box. The piston connecting rod blocks the movement trajectory line of the docking heads.

[0014] An installation method for prefabricated steel truss floor decking, using an installation device for prefabricated steel truss floor decking, includes the following steps:

[0015] (a) The paving trolley is lifted onto the existing steel beams of the steel structure building by a crane;

[0016] (b) Adjust the travel of the floor slab hoist so that the first floor deck can be accurately laid on the side steel beam parallel to the trajectory line of the laying trolley;

[0017] (c) Control the paving trolley to move in a straight line along the length of the steel beam and lay the floor decking onto the side steel beam one by one;

[0018] (d) The supplementary trolley is lifted by a crane onto the steel beam where the paving trolley is located, and the second storage area of ​​the supplementary trolley is filled with floor decking.

[0019] (e) After the floor decking of the paving trolley is used up, the replenishment trolley is moved towards the paving trolley until the replenishment trolley and the paving trolley are connected. Then the floor decking is replenished. After the replenishment is completed, the replenishment trolley is disengaged and returned to the initial position. Then the floor decking is filled again and the trolley is ready for the next replenishment operation.

[0020] (f) After the paving trolley has traveled the entire length of the steel beam, it completes the paving of the floor decking on one line. The paving trolley and the supplementary trolley are then hoisted onto the adjacent steel beam in sequence to carry out the paving of the floor decking on the next line.

[0021] The beneficial effects of this invention are:

[0022] 1. The paving trolley of the present invention can be adapted to be installed on building steel beams. It can travel along the length of the steel beams and can realize automated floor decking laying during the travel. The present invention is also designed with a supplementary trolley, which can replenish the floor decking of the paving trolley in real time to meet the needs of continuous paving.

[0023] 2. The application of this invention can greatly reduce the manual input in construction. Workers only need to complete equipment operation and finishing operations, which greatly reduces the time workers spend working at height and improves construction safety.

[0024] 3. This invention enables continuous straight-line paving of floor decking, which has the advantage of high construction efficiency. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] On the top of the assembled steel structure building, a top steel beam will be installed. The purpose of this invention is to lay a steel truss floor deck on the top steel beam, such as... Figures 1-6The device shown is an installation apparatus for prefabricated steel truss floor decking, including a paving trolley 1 and a crane chassis 2. The paving trolley 1 has a first storage area 11 on which floor decking to be paved is stacked. The crane chassis 2 is mounted on the platform of the paving trolley 1, and a paving crane 3 is movably mounted on the crane chassis 2. A floor decking lifting device 34 is mounted on the paving crane 3, which can grab the floor decking. The paving trolley 1 has a paving side 12, and the paving crane 3 can move towards the paving side 12. The floor decking can be lifted onto the steel beam in the direction of the paving side 12 by the floor decking lifting device 34. In use, the paving trolley 1 is lifted onto the top steel beam of the steel structure building by a crane. The paving trolley 1 is equipped with a remote control element. Ground staff remotely control the paving trolley 1 to move along the length of the steel beam. The paving crane 3 first grabs the floor decking in the first storage area 11 through the floor slab lifting device 34, and then moves towards the paving side 12 to lift the floor decking onto the steel beam in the paving side 12 direction (that is, the steel beam parallel to the paving trolley 1). As the paving trolley 1 moves, the lifting work continues. In this way, the floor decking can be laid in a straight line on the steel beam parallel to the paving trolley 1. This invention can better assist manual labor in completing the paving operation, greatly reduce the amount of manual labor required for paving, effectively improve paving efficiency, and eliminate the need for workers to work at height for long periods of time, thus improving construction safety.

[0034] like Figure 3 As shown, the crane chassis 2 includes a transmission frame 21, a crane drive assembly 22, and a crane base 23. The transmission frame 21 is fixedly installed on the platform of the paving trolley 1. The crane drive assembly 22 is installed inside the transmission frame 21. The crane base 23 is driven by the crane drive assembly 22. The paving crane 3 is fixedly installed on the crane base 23. The crane base 23 is driven to move by the crane drive assembly 22, thereby realizing the movement effect of the paving crane 3. The crane drive assembly 22 includes a transmission screw 221, guide rods 222, and a motor 223. The transmission screw 221 is rotatably installed inside the transmission frame 21, and the two guide rods 222 are respectively installed on the transmission frame 21. Guide rods 222 are fixedly installed on both sides of the screw 221. The output end of the motor 223 is connected to the transmission screw 221. The crane base 23 is mounted on the two guide rods 222 and threadedly connected to the transmission screw 221. The motor 223 can drive the transmission screw 221 to rotate. The guide rods 222 limit the movement direction of the crane base 23. When the transmission screw 221 rotates, the crane base 23 can move along the length of the guide rods 222. In this invention, the guide rods 222 are set perpendicular to the paving side 12. Therefore, the paving crane 3 can move towards the paving side 12 and can lift the floor deck onto the parallel side steel beam of the paving trolley 1.

[0035] like Figure 2As shown, the paving crane 3 includes a column 31, a crossbeam 32, and a crane beam 33. The bottom of the column 31 is fixedly connected to the crane base 23, and the column 31 is the main body of the paving crane 3. Since the paving crane 3 has a limited movement distance on the crane chassis 2, in order to allow the floor deck slab to be smoothly lifted out of the paving trolley 1 position, this invention also designs a second-stage movement stroke structure for the floor deck slab lifting device 34 (the first-stage movement stroke is achieved through the crane chassis 2). The second-stage movement stroke structure includes a crossbeam 32, which is fixedly connected to the top of the column 31. A guide rail 321 is laid on the crossbeam 32, and the guide rail 321 is laid along the length of the crossbeam 32. One end of the crane beam 33 is movably installed on the guide rail 321. A first push cylinder 322 is installed on the crossbeam 32, and the piston rod end of the first push cylinder 322 is connected to the crane beam 33. When the piston rod of the push cylinder 322 extends or retracts, it can drive the crane beam 33 to move along the length of the guide rail 321. Since the cross frame 32 and the guide rail 321 are set perpendicular to the paving side 12, when the piston rod of the first push cylinder 322 extends, the crane beam 33 can move towards the paving side 12. Several second push cylinders 331 are installed on the crane beam 33. The second push cylinders 331 are installed vertically downward. The floor slab lifting device 34 is connected to the piston rod end of the second push cylinder 331. When the piston rod of the second push cylinder 331 extends or retracts, it can form the lifting and lowering of the floor slab lifting device 34. The floor slab lifting device 34 is used to grab and place floor decking. The floor slab lifting device 34 first grabs a floor decking in the first storage area 11. Then, through the aforementioned two-stage movement stroke, the floor decking can move to the position above the parallel side steel beam of the paving trolley 1. As the floor slab lifting device 34 descends, the floor decking is laid on the steel beam.

[0036] To ensure all floor slabs are precisely laid in a straight line, this invention requires control of the travel stroke of the floor slab hanger 34. The second travel stroke of the floor slab hanger 34 is achieved by the extension of the piston rod of the first push cylinder 322. Since the extension length of the piston rod of the first push cylinder 322 is fixed, the length of the second travel stroke of the floor slab hanger 34 is also fixed. The first travel stroke of the floor slab hanger 34 is achieved by the crane chassis 2. By controlling the travel length on the crane chassis 2, the total travel stroke of the floor slab hanger 34 can be controlled, ensuring that all floor slabs are precisely laid in a straight line. Therefore, as... Figure 3As shown, the present invention has a stroke control bolt 24 and a linkage switch 25 installed on the transmission frame 21. The paving side 12 direction is the end of the stroke, so the stroke control bolt 24 and the linkage switch 25 are both installed in the paving side 12 direction. The stroke control bolt 24 and the linkage switch 25 block the movement path of the crane base 23. The stroke control bolt 24 determines the movement stroke of the crane base 23 on the crane chassis 2. When the paving trolley 1 lays the first floor deck, the worker needs to climb to calibrate the paving position and adjust the position of the stroke control bolt 24. After calibration, no further adjustment is needed before the same steel beam is laid. The present invention also includes a linkage structure, which is designed to control the first... The sequence of starting the first and second strokes is as follows: the floor slab hanger 34 needs to complete the first stroke first, and then complete the second stroke. In this invention, the linkage switch 25 is connected to the first push cylinder 322. When the crane base 23 contacts the stroke control bolt 24, the linkage switch 25 is triggered by the crane base 23, and the piston rod of the first push cylinder 322 extends in linkage. When the crane base 23 contacts the stroke control bolt 24, the floor slab hanger 34 has just completed the first stroke. At this time, the first push cylinder 322 is triggered to extend, and the second stroke begins. The above design of this invention can meet the stroke control requirements of the floor slab hanger 34 and ensure the accuracy of the floor decking installation.

[0037] like Figure 2 and Figure 4 As shown, the floor slab lifting device 34 includes a lifting platform 341. Two electromagnets 342 are installed below the lifting platform 341. When the floor slab lifting device 34 grabs the floor decking, the electromagnets 342 can precisely avoid the steel trusses on the slab. The electromagnets 342 contact the slab surface, and after being energized, they generate magnetism and can attract the floor decking. During the floor decking installation process, adjacent floor deckings need to be spot-welded together to form a whole. Therefore, this invention installs two symmetrically arranged welding components 343 on the lifting platform 341. The welding components 343 are set corresponding to the joint positions of the floor deckings. The welding components 343 include a third push cylinder 3431 and a lifting linkage plate 3432. Several third push cylinders 3431 are arranged in a row and installed vertically downwards on the lifting platform 341. Figure 5 As shown, the lifting linkage plate 3432 is connected to the piston rod end of the third push cylinder 3431. Several welding guns 3433 are installed on the bottom surface of the lifting linkage plate 3432. The third push cylinder 3431 can drive the lifting linkage plate 3432 to rise and fall, realizing the extension and retraction of the welding guns 3433. The welding guns 3433 correspond to the welding points. The welding guns 3433 rise and retract to ensure that the welding guns 3433 will not collide with the plate surface and be damaged when grabbing the floor deck. Several cameras need to be installed on the paving trolley 1 and the floor deck hoist 34 of this invention. The cameras can facilitate the operator to observe the paving of the floor deck and remotely complete the paving operation.

[0038] In steel structure buildings, the steel beams are often quite long, requiring a large number of floor decking slabs. The amount of floor decking slabs on the paving trolley itself is insufficient to meet the paving needs. Therefore, if... Figure 1 As shown, this invention equips the paving trolley 1 with a replenishment trolley 5. The replenishment trolley 5 carries the floor decking that needs to be replenished, and can replenish the paving trolley 1 with materials in a timely manner. The paving trolley 1 is provided with a floor decking replenishment port 13. The replenishment trolley 5 is hoisted onto the steel beam on which the paving trolley 1 is located. The replenishment trolley 5 can move along the same trajectory line as the paving trolley 1. The replenishment trolley 5 can dock with the floor decking replenishment port 13 of the paving trolley 1. The replenishment trolley 5 is provided with a second storage area 51. The floor decking to be replenished is stacked in the second storage area 51. The replenishment trolley 5 is equipped with a boarding conveyor belt 52, which is located at the second storage area 51. The boarding conveyor belt 52 can carry out the replenished floor decking at the second storage area 51. The paving trolley 1 is equipped with an infeed conveyor belt 14, which picks up the floor decking replenished from the floor decking. The filling port 13 starts and extends into the first storage area 11. The board feeding conveyor belt 14 is used to pick up and bring in the supplementary floor decking. Since it is necessary to ensure the accurate installation of the floor decking, the supplementary floor decking needs to be accurately stacked in the first storage area 11. First, there is a fixed obstruction in the forward direction of the board feeding conveyor belt 14 to make the floor decking advance and fall into place. Second, the first storage area 11 of the paving trolley 1 and the second storage area 51 of the supplementary trolley 5 are both equipped with correction components 4. The correction components 4 are used to straighten the position of the floor decking so that the floor decking is placed accurately. The correction components 4 include a fourth push cylinder 41 and a correction push plate 42. The correction push plate 42 is connected to the piston rod end of the fourth push cylinder 41. The correction push plate 42 is installed facing the inside of the storage area. When straightening, the two correction components 4 are activated simultaneously to form a straightening effect.

[0039] like Figure 1 As shown, in the first storage area 11 of the paving trolley 1, three sides are blocked, and the remaining side is set as an open side. The open side of the first storage area 11 faces the floor slab replenishment opening 13. This open side is used for floor decking replenishment operations. Two opening and closing stops 6 are symmetrically installed at the open side of the first storage area 11. The opening and closing stops 6 can control the opening and closing of the open side of the first storage area 11. Figure 6As shown, the opening / closing stop 6 includes a stop box 61 and a linkage box 62. The stop box 61 is fixedly installed on the platform of the paving trolley 1, and the linkage box 62 is installed on the body of the paving trolley 1. A first piston 611 is installed inside the stop box 61. One side of the first piston 611 is configured as a first oil chamber 612, and a spring 613 is installed on the other side of the first piston 611. Two stop rods 614 are connected to the first piston 611 and are installed on the side of the first oil chamber 612. The first oil chamber 612 extends through to the outside of the stop box 61. A second piston 621 is installed inside the linkage box 62. One side of the second piston 621 is configured with... The second oil chamber 622 has a piston connecting rod 623 installed on the other side of the second piston 621. The piston connecting rod 623 is fixedly connected to the second piston 621. The first oil chamber 612 and the second oil chamber 622 are connected by pipelines. The first oil chamber 612 and the second oil chamber 622 are filled with hydraulic oil. The supplementary trolley 5 is connected to two docking heads 53. The docking heads 53 are set one-to-one with the linkage box 62. The piston connecting rod 623 blocks the movement trajectory line of the docking head 53. When the supplementary trolley 5 supplements the paving trolley 1 with floor decking, the supplementary trolley 5 moves toward the paving trolley 1, and the docking heads 53 can hit and push the piston connecting rod. 623, the piston connecting rod 623 can push the second piston 621 to move towards the second oil chamber 622, so that the hydraulic oil in the oil chamber is squeezed into the first oil chamber 612, pushing the first piston 611 to move towards the spring 613. At this time, the spring 613 is compressed, and the stop rod 614 also forms an inward effect. As the replenishing trolley 5 and the paving trolley 1 are fully engaged, the stop rod 614 is retracted to its limit, and the stop rod 614 can no longer block the opening of the first storage area 11, forming an opening effect. At this time, the floor decking replenishment operation can be carried out. After the floor decking replenishment operation is completed, the replenishing trolley 5 gradually engages with the paving trolley. As the trolley 1 disengages, the piston connecting rod 623 gradually loses its thrust. Under the restoring force of the spring 613, the first piston 611 is pushed in the opposite direction, and the hydraulic oil in the first oil chamber 612 is squeezed out of the second oil chamber 622. At this time, the piston connecting rod 623 gradually returns to its original position, and the stop rod 614 also extends outward to return to its original position. After the stop rod 614 extends outward, it can block the opening of the first storage area 11, preventing the floor deck from sliding out from the opening. After the stop rod 614 extends outward, there is a blockage on all four sides of the first storage area 11, ensuring that the placement position of the floor deck is determined. This can help improve the installation accuracy of the floor deck.

[0040] In this invention, since the paving crane 3 needs to move frequently towards the paving side 12, a counterweight 15 is installed on the paving trolley 1 to balance the center of gravity in order to prevent the paving crane 3 from tipping over. All the push cylinders in this invention are electric push cylinders. The paving trolley 1 in this invention is equipped with a battery pack, which can supply power to all the push cylinders, as well as motors and other electrical equipment. The paving crane 3 and the supplementary trolley 5 in this invention are equipped with cameras, which can transmit images in real time, making it convenient for workers to remotely operate them.

[0041] An installation method for prefabricated steel truss floor decking, using an installation device for prefabricated steel truss floor decking as described above, includes the following steps:

[0042] (a) The paving trolley 1 is lifted onto the existing steel beams of the steel structure building by a crane;

[0043] (b) Adjust the travel of the floor slab hoist 34 so that the first floor deck can be accurately laid on the side steel beam parallel to the trajectory line of the laying trolley 1. The laying of the first floor deck of each group of steel beams is the most important and should be used as a benchmark. When laying the first floor deck, workers need to climb to a height to cooperate in the operation. The travel of the floor slab hoist 34 is achieved by adjusting the travel control bolt 24. After the first floor deck is laid accurately, subsequent continuous and accurate laying can be guaranteed.

[0044] (c) After the first floor decking is laid, the laying trolley 1 is controlled to move in a straight line along the length of the steel beam and lay the floor decking one by one onto the side steel beam. Spot welding is also completed during the laying process.

[0045] (d) The paving trolley 1 carries a storage plate. The paving trolley 1 first uses the storage plate to pave. During this process, the supplementary trolley 5 is lifted by a crane onto the steel beam where the paving trolley 1 is located, and the second storage plate area 51 of the supplementary trolley 5 is filled with floor decking.

[0046] (e) After the floor decking of the paving trolley 1 is used up, the replenishment trolley 5 is moved towards the paving trolley 1 until the replenishment trolley 5 and the paving trolley 1 are connected. Then the floor decking replenishment operation is carried out. After the replenishment is completed, the replenishment trolley 5 is disengaged and returned to the initial position. Then the floor decking is filled again and the trolley is ready for the next replenishment operation.

[0047] (f) After the paving trolley 1 has traveled the entire length of the steel beam, it completes the paving of the floor decking along one line. The paving trolley 1 is then replenished with floor decking and then lifted by a crane to the adjacent steel beam for the next set of steel beams to be laid. The replenishment trolley 5 is then lifted by the paving trolley 1, and the two continue to work together to complete the paving operation.

[0048] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
