Description

Technical Field

[0001] This invention relates to the field of steel truss floor decking technology, and in particular to a prefabricated assembled steel truss floor decking welding construction device and its usage method. Background Technology

[0002] Floor decking refers to pressed steel plates that support concrete floor surfaces. It meets the requirements of rapid construction of the main steel structure and can provide a stable working platform in a short time. Among them, steel truss floor decking is made by welding the upper and lower longitudinal steel bars with bent small-diameter steel bars to form a small truss with a certain rigidity and the ability to bear loads. The small truss is then welded to profiled steel sheets and then made by casting concrete in place.

[0003] Chinese patent CN115815936A discloses a welding and processing device for steel truss floor decking, including a base plate, a first support column fixedly installed on the top of the base plate, a support plate fixedly installed on the top of the first support column, a sliding rod fixedly installed on the top of the support plate, a bracket fixedly installed at one end of the sliding rod, a second motor fixedly installed at the bottom of the bracket, a second gear fixedly installed at the output end of the second motor, and a second slide rail fixedly installed on the top of the bracket, etc.

[0004] However, the aforementioned device is prone to positional deviation when placing the steel truss, which requires constant positional adjustment when welding the steel truss and steel plate, affecting the welding process and thus reducing welding efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that in the prior art, when placing steel trusses, positional deviation is easy to occur, which requires constant positional adjustment when welding steel trusses and steel plates, affecting the welding process and thus reducing welding efficiency. Therefore, this invention proposes a prefabricated assembled steel truss floor deck welding construction device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated assembled steel truss floor deck welding construction device includes: an installation plate, two installation plates are arranged in parallel and symmetrically, and a plurality of guide plate assemblies are arranged in the middle, the plurality of guide plate assemblies being used to drive the floor deck;

[0008] A frame plate is fixedly connected to two of the side frames. The frame plate is inverted U-shaped. Multiple adjustment components are provided below the top wall of the frame plate. The multiple adjustment components are correspondingly arranged with multiple guide plate components. Clamping components are symmetrically arranged on both sides of the adjustment components. Two clamping components are used to drive the truss. Each clamping component includes a control plate, a drive motor, a rotating column, a mounting belt, a limit block, a clamping block, and a magnetic block. The two control plates are fixedly connected in parallel and symmetrically on both sides of the adjustment components. The two drive motors are fixedly installed at both ends of the lower side of the control plates. The rotating column is fixedly connected below the drive motor. The mounting belt is sleeved between the two rotating columns. The limit block is fixedly connected below the rotating column to limit the position of the mounting belt. Multiple clamping blocks are fixedly connected at equal intervals to the side of the mounting belt. A semi-circular groove is opened on the side of the clamping block away from the mounting belt. An installation groove is opened in the middle of the semi-circular groove. The clamping block is made of elastic material. The magnetic block is fixedly installed inside the installation groove.

[0009] Preferably, the adjustment assembly includes a telescopic cylinder and a telescopic rod. The telescopic cylinder is vertically fixedly connected to the bottom of the frame plate, and the telescopic rod is vertically fixedly connected to the bottom of the telescopic cylinder, with the telescopic rod extending and retracting to both sides.

[0010] Preferably, the guide plate assembly includes guide wheels, a transmission belt, and a motor. The two guide wheels are rotatably disposed inside the mounting plate, the transmission belt is sleeved between the two guide wheels, and the motor is fixedly mounted on the outside of the mounting plate, with its output end fixedly connected to the guide wheels.

[0011] Preferably, the discharge end of the guide plate assembly is provided with a moving component, which is used to move the floor deck and truss.

[0012] Preferably, the moving component includes a side plate, a linkage shaft, and a transmission wheel. The two side plates are symmetrically arranged, and the multiple linkage shafts are equidistantly rotatably arranged between the two side plates. The multiple transmission wheels are fixedly sleeved on the linkage shafts. The diameter of the transmission wheels gradually increases from the direction of the guide plate assembly to the other side, for contact between the truss and the floor deck.

[0013] Preferably, the side plate has multiple sliding grooves equidistantly spaced on its upper side, and a sliding component is slidably disposed inside the sliding groove.

[0014] Preferably, the sliding assembly includes a sliding rod and a sliding bar, with the two sliding rods slidably disposed inside symmetrical sliding grooves on both sides, and the sliding bar fixedly connected to the upper ends of the two sliding rods.

[0015] Preferably, spot welding components are fixedly installed on the sliding bar, and the two spot welding components are respectively arranged corresponding to the two clamping components, and are used to spot weld the connection between the floor deck and the truss.

[0016] Preferably, the spot welding assembly includes a drive block, a moving cylinder, and a welding head. The drive block is fixedly mounted on the sliding bar, the moving cylinder is fixedly connected below the sliding bar, and the welding head is fixedly connected to the lower end of the moving cylinder, for welding the floor deck and truss.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Since the truss is composed of multiple triangular steel structures and a set of steel rods, when the truss is moved, the steel rods are clamped by clamping blocks on both sides. At the same time, the rotating column drives the clamping blocks to move via the transmission belt, thereby moving the steel rods. However, due to the weight of the steel rods, slippage between the steel rods and the clamping blocks may occur, affecting the alignment with the steel plate. The internal magnetic blocks are magnetically connected to the steel rods, thereby strengthening the fixation of the steel rods and ensuring stable movement. The telescopic cylinder drives the control plate to move up and down, while the drive motor drives its clamping blocks to rotate. This works in conjunction with the guide plate assembly to coordinate the movement of the truss and the steel plate, thereby ensuring the synchronous movement and stillness of the truss and the steel plate. This invention can effectively limit the truss and ensure the movement between the truss and the steel plate, improving the welding efficiency of prefabricated steel truss floor decks.

[0019] 2. In order to ensure effective fixation of different trusses, the distance between the clamping blocks on both sides is adjusted by the telescopic rods that extend and retract left and right, so as to effectively clamp and fix the steel rods. At the same time, since different trusses are of different sizes, in order to ensure close contact between the truss and the steel plate, the clamping components are moved up and down by controlling the telescopic cylinder to make the truss contact the steel plate.

[0020] 3. The diameter of the drive wheel gradually increases from the guide plate assembly to the other side, which is used for the contact between the truss and the floor deck. The rotating linkage shaft and drive wheel drive the steel plate and the truss in contact with the steel plate to move, thereby ensuring the manufacturing of the steel truss.

[0021] 4. In order to ensure a firm welded connection, the welding requires long strip-shaped welding points. The sliding rod is controlled by a sliding block to slide within the sliding groove, thereby driving the sliding strip to slide. At the same time, it drives the spot welding components installed on the sliding strip to move, ensuring the welding between the steel trusses. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0030] Reference Figures 1-5 A prefabricated steel truss floor deck welding construction device includes: an installation plate 1, two installation plates 1 are arranged in parallel and symmetrically, and multiple guide plate assemblies 2 are arranged in the middle, the multiple guide plate assemblies 2 are used to drive the floor deck;

[0031] Two mounting plates 1 are fixedly connected to a frame plate 3, which is inverted U-shaped. Multiple adjustment components 4 are located below the top wall of the frame plate 3, corresponding to multiple guide plate components 2. Clamping components 5 are symmetrically arranged on both sides of the adjustment components 4. Two clamping components 5 are used to drive the truss. Each clamping component 5 includes a control plate 51, a drive motor 52, a rotating column 53, a mounting belt 54, a limit block 55, a clamping block 56, and a magnetic block 57. Two control plates 51 are fixedly and symmetrically connected to both sides of the adjustment components 4. Two drive motors 52 are fixedly installed at the lower ends of the control plates 51. The rotating column 53 is fixedly connected below the drive motor 52. The mounting belt 54 is fitted between the two rotating columns 53. The limit block 55 is fixedly connected below the rotating column 53 to limit the position of the mounting belt 54. Multiple clamping blocks 56 are equidistantly fixedly connected to the sides of the mounting belt 54, with the clamping blocks 56 being far from the mounting belt. A semi-circular slot is provided on one side of belt 54, and an installation groove is provided in the middle of the semi-circular slot. The clamping block 56 is made of elastic material, and the magnetic block 57 is fixedly installed inside the installation groove. Since the truss is connected by multiple triangular steel structures and a set of steel rods, when the truss is moved, the steel rods are clamped by the clamping blocks 56 on both sides. At the same time, the drive motor 52 drives the rotating column 53 to rotate, which in turn drives the clamping block 56 to move, thereby moving the steel rods. At the same time, due to the weight of the steel rods, the steel rods may slip between the clamping blocks 56 and the steel plate, affecting the alignment with the steel plate. The magnetic block 57 inside is magnetically connected to the steel rod, thereby strengthening the fixation of the steel rod position and ensuring that the steel rods can move stably. The drive motor 52 and the guide plate assembly 2 move in coordination to ensure the synchronous movement and stillness of the truss and the steel plate.

[0032] In the embodiments applying the above technical solution, since the truss is composed of multiple triangular steel structures and a set of steel rods, when the truss is moved, the steel rods are clamped by the clamping blocks 56 on both sides. At the same time, the drive motor 52 drives the rotating column 53 to rotate, which in turn drives the clamping blocks 56 to move, thereby moving the steel rods. However, due to the weight of the steel rods, slippage may occur between the steel rods and the clamping blocks 56, affecting the alignment with the steel plate. The internal magnetic block 57 is magnetically connected to the steel rod, thereby strengthening the fixation of the steel rod position and ensuring that the steel rods can move stably. The drive motor 52 and the guide plate assembly 2 move in coordination, thereby ensuring the synchronous movement and stillness of the truss and the steel plate. This invention can effectively limit the truss and ensure the movement between the truss and the steel plate, improving the welding efficiency of prefabricated assembled steel truss floor slabs.

[0033] In this preferred embodiment, the adjusting component 4 includes a telescopic cylinder 41 and a telescopic rod 42. The telescopic cylinder 41 is vertically fixedly connected to the bottom of the frame plate 3, and the telescopic rod 42 is vertically fixedly connected to the bottom of the telescopic cylinder 41. The telescopic rod 42 is extended and retracted to both sides, which is a double movable elastic telescopic rod. Since the diameter of the steel rods used in different specifications of trusses is different, in order to ensure effective fixation of different trusses, the distance between the clamping blocks 56 on both sides is adjusted by the left and right flexible telescopic rod 42, so as to effectively clamp and fix the steel rods. At the same time, since different trusses are different in size, in order to ensure close contact between the truss and the steel plate, the clamping component 5 is moved up and down by controlling the telescopic cylinder 41 to make the truss contact the steel plate.

[0034] The guide plate assembly 2 includes guide wheels 21, a transmission belt 22, and a motor 23. The two guide wheels 21 are rotatably mounted inside the mounting plate 1, and the transmission belt 22 is sleeved between the two guide wheels 21. The motor 23 is fixedly mounted on the outside of the mounting plate 1, and its output end is fixedly connected to the guide wheels 21. The steel plate is placed on the transmission belt 22 and the guide wheels 21 are driven to rotate by the motor 23. At the same time, the rotation of the motor 23 is synchronized with the start and stop of the drive motor 52 above, which is used to ensure the simultaneous movement and stopping of the truss and the steel plate.

[0035] The discharge end of the guide plate assembly 2 is equipped with a moving component 6. The moving component 6 is used to drive the floor deck and truss to move. After the truss and steel plate are fed through the guide plate assembly 2 and the clamping assembly 5, the moving component 6 ensures the movement of the material, thereby ensuring the subsequent welding process.

[0036] The movable component 6 includes a side plate 61, a linkage shaft 62, and a transmission wheel 63. The two side plates 61 are symmetrically arranged, and multiple linkage shafts 62 are equidistantly rotatably arranged between the two side plates 61. Multiple transmission wheels 63 are fixedly sleeved on the linkage shafts 62. The diameter of the transmission wheels 63 gradually increases from the direction of the guide plate component 2 to the other side, gradually pushing the steel plate upward for contact between the truss and the floor deck. The rotating linkage shafts 62 and transmission wheels 63 drive the steel plate and the truss in contact with the steel plate to move, thereby ensuring the manufacturing of the steel truss.

[0037] Multiple sliding grooves 9 are equidistantly provided on the upper side of the side plate 61, and sliding components 7 are slidably disposed inside the sliding grooves 9;

[0038] The sliding assembly 7 includes a sliding rod 71 and a sliding bar 72. The two sliding rods 71 ​​are slidably disposed inside the symmetrical sliding grooves 9 on both sides. The sliding bar 72 is fixedly connected to the upper end of the two sliding rods 71. In order to ensure a firm welded connection, the welding requires a long strip-shaped welding point. The sliding rod 71 is limited to slide within the sliding groove 9 by a sliding block, thereby driving the sliding bar 72 to slide. At the same time, it drives the spot welding assembly 8 installed on the sliding bar 72 to move, ensuring the welding between the steel trusses.

[0039] A spot welding assembly 8 is fixedly installed on the sliding bar 72. The two spot welding assemblies 8 are respectively set with the two clamping assemblies 5 and are used to spot weld the connection between the floor deck and the truss.

[0040] The spot welding assembly 8 includes a drive block 81, a moving cylinder 82, and a welding head 83. The drive block 81 is fixedly mounted on the sliding bar 72, the moving cylinder 82 is fixedly connected to the bottom of the sliding bar 72, and the welding head 83 is fixedly connected to the lower end of the moving cylinder 82. It is used for welding the floor deck and the truss. The drive block 81 has a built-in control module to make the piston end of the moving cylinder 82 of the drive block 81 extend or retract. At the same time, when the truss and steel plate are moved to the appropriate position, the welding head 83 below is used to weld the components between the steel trusses.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
