Abstract
Description
Technical Field
[0001] This utility model relates to welding equipment in the field of building engineering, and in particular to a welding equipment for a composite wall panel steel mesh truss non-removable formwork assembly. Background Technology
[0002] With the implementation of the "Evaluation Standard for Green Buildings" (2024 revised edition), the standards for building energy conservation and green buildings are becoming increasingly stringent. Provinces and cities in the temperate southern regions have raised their building energy conservation standards to 75% for near-zero energy consumption buildings, while provinces and cities in the cold northern regions have raised their standards to 85% for ultra-low energy consumption buildings. These standards are mandatory local standards and are strictly enforced during the planning review, drawing review, construction, supervision, completion acceptance, and document filing processes of construction projects.
[0003] JG / T578-2021, the national industry standard "Technical Requirements for Wall Panels for Prefabricated Buildings", stipulates in clauses 3.5, 3.6, 3.8, and 3.9 that for various types of frame wall panels and walls using light steel keel as the wall skeleton (frame), clause 5.3.9 states that the fire performance of exterior wall panels should not be lower than the non-combustible Class A requirement in GB 8624. The original wall panels and walls using fire-retardant B1-grade insulation materials such as polystyrene foam boards and extruded polystyrene boards as wall panels and wall insulation filling layers, as well as low-grade wall panels and walls with a compressive strength of 3.5 MPa and low water absorption and brittleness, are no longer able to meet the current stringent requirements of Class A fire resistance, building energy conservation and green building standards. At the same time, in order to improve the wall's seismic resistance and wind load resistance, and overcome defects such as wall hollowness, shelling, peeling and cracking, the applicant proposed an integrated insulation wall with a steel mesh truss and a template-free design, as described in Chinese utility model patent application CN202411483417.8 (publication number CN119243901A). The inner core of this insulation wall is provided with a truss welding assembly of template-free design, keel and steel mesh on both sides. However, this "truss welding assembly" is used in large quantities and needs to be mass-produced. If the existing manual welding method is used, the production efficiency is low and the quality is unstable. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a composite wall panel steel mesh truss welding equipment that does not require dismantling the formwork. It can achieve batch welding of "truss welding components" consisting of a bottom formwork and a steel mesh sandwiched with light steel keel. The equipment has a simple structure, stable and uniform welding quality, and high production efficiency.
[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0006] A composite wall panel steel mesh truss non-removable formwork welding equipment includes a bed platform and a welding device. The bed platform includes a first conveying platform and a second conveying platform arranged in an upstream-downstream sequence. The two conveying platforms are respectively equipped with a material conveying device and a locking mechanism, and the welding device is provided at the tail end of the two conveying platforms.
[0007] The first material conveying device of the first conveying platform includes a bottom template conveying frame and a support truss conveying frame that are connected upstream and downstream. The bottom template conveying frame is used to convey the bottom template to the first conveying platform, and the support truss conveying frame is used to convey the support truss keel to the bottom template that is in place on the first conveying platform. The locking mechanism and welding device of the conveying platform are used to clamp and lock the support truss keel and the bottom template and to perform multi-point welding, respectively.
[0008] The second material conveying device is used to convey steel mesh to the second conveying platform. When the welded semi-finished product conveyed by the first conveying platform arrives at the set position of the second conveying platform, the steel mesh is conveyed and placed on the welded semi-finished product and clamped and locked by the locking mechanism of the conveying platform, and then conveyed to the welding device at the tail end for multi-point welding.
[0009] The welding device is equipped with multiple sets of upper and lower welding heads. Each set of welding heads completes multi-point welding in the same horizontal row. Then, each conveying platform longitudinally feeds the parts to complete the multi-point welding in the next horizontal row.
[0010] The above technical solution involves setting up a first conveying platform and a second conveying platform to transport the parts to be welded. When the supporting truss keel is placed in a set position on the bottom template, the locking mechanism on the first conveying platform locks the supporting truss keel and the bottom template and moves longitudinally along with the first conveying platform. The first supporting truss keel stops moving when it reaches between the upper and lower welding heads of the welding device. Each group of welding heads completes multi-point welding of the first supporting truss keel. At this time, the second supporting truss keel is positioned and fixed with the bottom template. Then, the first conveying platform moves longitudinally, and this cycle is repeated to complete the welding of the second, third to Nth supporting truss keels with the same bottom template. The first conveying platform continues to transport the just-completed welded semi-finished products to the second conveying platform. Reinforcing mesh is placed on each supporting truss keel, and similar multi-point welding of each row is completed by the welding device. The reinforcing mesh is welded together with the supporting truss keel and the bottom template to form the finished welded assembly.
[0011] Furthermore, to ensure reliable operation and a compact structure, after the welding devices of the two conveying platforms complete the welding points of the last row of workpieces to be welded, the conveying platforms output the welded semi-finished products or welded finished products, and then the conveying platforms return to the starting position.
[0012] Furthermore, the locking mechanism is installed on the two conveying platforms. After locking the workpiece to be welded, it moves longitudinally along with the conveying platform. After the welding device completes the welding of the last row of welding points, the locking mechanism opens.
[0013] Furthermore, in order to achieve multi-point welding in the same row, the welding device includes a gantry spanning across, on which are arranged multiple sets of upper and lower welding heads that are positioned opposite each other. The upper and lower welding heads are driven by programmable pneumatic devices.
[0014] Furthermore, as an optimized solution, the two conveying platforms are driven by a programmable pneumatic device or a servo motor, and the conveying platforms move longitudinally at set intervals. The conveying platforms are fixed to the ground by a frame.
[0015] Furthermore, based on production volume and optimal cost-effectiveness, the first and second material conveying devices are material placement platforms, where materials are conveyed manually or by robotic arms to the first conveying platform or the designated position of the workpiece to be welded.
[0016] Furthermore, to facilitate the output of welded finished parts and the output and management of the unloading station, a third conveying platform located downstream of the second conveying platform and a finished product output device on one side of the third conveying platform are also included. The third conveying platform is used to transport the welded finished parts completed by the second conveying platform.
[0017] Furthermore, depending on the production volume and equipment cost-effectiveness, the welded finished products on the third conveying platform are placed on the finished product output device by manual labor or a robotic arm.
[0018] In summary, the beneficial effects of this utility model are: for the "steel mesh truss formwork without dismantling" component of the three-dimensional structure, it can achieve semi-automatic batch welding at a lower cost, and the equipment structure is simple, the welding quality is stable and uniform, the production efficiency is high, which is conducive to the promotion and use of wall panels for prefabricated buildings.

[0027] The "steel mesh truss formwork without dismantling" assembly to be welded by the welding equipment in the following embodiments, such as Figure 1 and Figure 2 As shown (see also the publication of Chinese utility model patent application CN202411483417.8), the "reinforced mesh truss formwork" assembly includes a bottom formwork 21, a reinforcing mesh 23, and supporting truss ribs 22. Multiple supporting truss ribs 22 connect the bottom formwork 21 and the reinforcing mesh 23 into a single unit. Each wall panel requires two spaced "reinforced mesh truss formworks," with an insulation core 24 between the two "reinforced mesh truss formworks," and lightweight concrete 25 outside the "reinforced mesh truss formworks." The bottom formwork 21 is provided with several upward-protruding parallel reinforcing ribs 211, which can also serve as welding points for butt welding with the supporting truss ribs 22.
[0028] In the following example description, the direction "forward" refers to the starting position of the material feeding at the bottom template of the welding equipment, and the direction "backward" is opposite to "forward" and refers to the direction of the welded part being discharged from the welding equipment. "Upstream side" refers to a direction relatively closer to "forward," and "downstream side" refers to a direction relatively closer to "backward." Furthermore, the terms "first," "second," and "third" are used only for description and should not be construed as indicating or implying relative importance. It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] Example 1: As Figures 3-5As shown, a composite wall panel steel mesh truss non-removable formwork welding equipment includes a bed platform and a welding device 4. The bed platform includes a first conveying platform 1 and a second conveying platform 2 arranged in an upstream-downstream sequence. Each conveying platform is equipped with a material conveying device and a locking mechanism 3. The welding device 4 is located at the tail end of each conveying platform and is connected to the conveying platform. The two conveying platforms are fixed to the ground by a frame. The conveying platforms are driven by a programmable pneumatic device or a servo motor. In this embodiment, a servo motor drives the transmission rollers as the conveying platform, which moves longitudinally at set intervals under the control of the control unit, i.e., travels in the front-to-back direction.
[0030] The first material conveying device of the first conveying platform 1 includes a bottom template conveying frame 5 and a supporting truss conveying frame 6, which are connected upstream and downstream. The bottom template conveying frame 5 and the supporting truss conveying frame 6 are located on the same side of the first conveying platform 1, with the bottom template conveying frame 5 closer to the upstream side. The supporting truss conveying frame 6 is located behind the bottom template conveying frame 5. The bottom template conveying frame 5 is used to convey the bottom template 21 onto the first conveying platform 1, and the supporting truss conveying frame 6 is used to convey the supporting truss keel 22 onto the bottom template 21 that is in place on the first conveying platform 1. Depending on the production volume and optimal cost-effectiveness, the bottom template conveying frame 5 and the supporting truss conveying frame 6 can be used as material placement platforms, where the bottom template 21 is conveyed to the first conveying platform 1 manually or by a robotic arm, or the supporting truss keel 22 is placed in a predetermined position on the bottom template 21. The first conveying platform 1 is equipped with a locking mechanism 3 for clamping and locking the supporting truss keel 22 and the bottom template 21, while a welding device 4 is used for multi-point welding of the supporting truss keel 22 and the bottom template 21.
[0031] like Figures 4 to 7 As shown, the second material conveying device 7 is used to convey the reinforcing mesh 23 to the second conveying platform 2. When the welded semi-finished product conveyed by the first conveying platform 1 arrives at the set position of the second conveying platform 2, the reinforcing mesh 23 is conveyed and placed on the welded semi-finished product and clamped and locked by the locking mechanism 3 of the conveying platform, and then conveyed to the welding device 4 at the tail end for multi-point welding. The second material conveying device 7 is a material placement platform. The reinforcing mesh 23 is conveyed to the welded semi-finished product by manpower or a robotic arm. The reinforcing mesh 23 is placed above the supporting truss keel 22, and the welding device 4 welds multiple supporting truss keels 22 to the reinforcing mesh 23.
[0032] like Figure 3 , Figure 5 and Figure 7The welding device 4 of the first conveying platform 1 and the second conveying platform 2 shown includes a spanning gantry frame. Multiple sets of upper welding heads 41 and lower welding heads 42 are arranged vertically opposite each other on the gantry frame. Each set of welding heads completes multi-point welding in the same horizontal row at time intervals. Then, the conveying platforms longitudinally move the workpiece to complete the multi-point welding in the next horizontal row. The welding heads complete multi-point welding in the same horizontal row at time intervals, rather than simultaneously, to avoid excessive discharge, energy consumption, and equipment limitations. To achieve multi-point welding in the same row, the upper welding heads 41 and lower welding heads 42 are driven by programmable pneumatic devices. During welding, the programmable pneumatic devices drive each upper welding head 41 to press down at time intervals, while the lower welding head 42 pushes up to fix the workpiece to be welded.
[0033] To ensure reliable operation and a compact structure, after the welding device 4 of the two conveying platforms completes the welding points of the last row of workpieces to be welded, the conveying platform outputs the semi-finished or finished welded products from the welding device 4, and then the conveying platform returns to the starting position.
[0034] The locking mechanism 3 is installed on the two conveying platforms. After locking the workpiece to be welded, it moves longitudinally along with the conveying platform. After the welding device 4 completes the welding of the last row of welding points, the locking mechanism 3 opens. The locking mechanism 3 can be a pneumatic pressure block or a pneumatic rotating block. Both are driven by a cylinder to the connecting part, which in turn drives the pressure block to move up and down or the rotating block to rotate in the clockwise or counterclockwise direction. The connecting part can be a push rod connected to the pressure block or a gear and rack mechanism that drives the rotating block to rotate, thereby locking or unlocking the locking mechanism 3. This is a known prior art.
[0035] The above technical solution, by setting up a first conveying platform 1 and a second conveying platform 2 for conveying the parts to be welded, when the supporting truss keel 22 is placed in a set position on the bottom template 21, the locking mechanism 3 on the first conveying platform 1 locks the supporting truss keel 22 and the bottom template 21 and moves longitudinally with the first conveying platform 1. The first supporting truss keel 22 stops moving when it reaches between the upper welding head 41 and the lower welding head 42 of the welding device 4. Each group of welding heads completes multi-point welding of the first supporting truss keel 22 with a time difference. The second supporting truss keel 22 is positioned and fixed with the bottom template 21. Then, a conveying platform moves longitudinally, and this cycle is repeated to complete the welding of the second, third to Nth supporting truss keels 22 with the same bottom template 21. The first conveying platform 1 continues to convey and push the just-completed welded semi-finished product to the second conveying platform 2. Steel mesh 23 is placed on each supporting truss keel 22, and similar multi-point welding of each row is completed by the welding device 4. The steel mesh 23 is welded together with the supporting truss keel 22 and the bottom template 21 to form the finished welded component.
[0036] The welding method for the composite wall panel using a steel mesh truss template without disassembly includes the following steps: (1) The bottom template 21 is placed on the bottom template conveying frame 5 of any of the above-mentioned welding equipment, and the bottom template 21 is conveyed to the first conveying platform 1 by the conveying frame. The first conveying platform 1 moves and conveys the bottom template 21 to the set position and stops. The supporting truss conveying frame 6 conveys the first supporting truss keel 22 to the first row of welding positions on the bottom template 21; (2) The locking mechanism 3 positions and locks the supporting truss keel 22 to the bottom template 21 and moves longitudinally with the first conveying platform 1. The first row of welding positions stops moving when it reaches between the upper and lower welding heads 42 of the welding device 4. Each group of welding heads completes the first row of multi-point welding with a time difference. At this time, the supporting truss conveying frame 6 conveys the second supporting truss keel 22 to the second row of welding positions on the bottom template 21 and locks it by the locking mechanism 3; (3) The first conveying platform 1 moves longitudinally, and when it pauses, it completes the multi-point welding of the second supporting truss keel 22 and the positioning and locking of the third supporting truss keel 22. This cycle continues until the last row of multi-point welding is completed. The locking mechanism 3 is opened, and then the first conveying platform 1 outputs the welded semi-finished product to the second conveying platform 2 and returns to the starting position. (4) When the welded semi-finished product on the second conveying platform 2 reaches the set position, the steel mesh 23 is conveyed by the second material conveying device 7 and placed on the welded semi-finished product. Then, it is clamped and locked by the locking mechanism 3 of the second conveying platform 2 and then conveyed together to the welding device 4 at the tail end to perform the first row of multi-point welding. The steel mesh 23 is welded to the first supporting truss keel 22. Then, the second conveying platform 2 moves, and this cycle continues until the last row of multi-point welding is completed. The locking mechanism 3 is opened, and then the second conveying platform 2 outputs the welded product and returns to the starting position.
[0037] By applying the above-mentioned welding method for composite wall panel steel mesh truss non-removable formwork, the steel mesh 23 can be welded together with the supporting truss keel 22 and the bottom formwork 21 at a lower cost and semi-automatically to form a three-dimensional "steel mesh truss non-removable formwork" welding component. This achieves low-cost batch welding, stable and uniform welding quality, high production efficiency, and enables mass production in the factory.
[0038] Example 2: Figure 8As shown, the structure and positional relationship of this embodiment are basically the same as those of embodiment 1. The difference is that, in order to facilitate the output of welded finished parts and the output and management of the material unloading station, a third conveying platform 8 located downstream of the second conveying platform 2 and a finished product output device 9 on one side of the third conveying platform 8 are also included. The third conveying platform 8 is used to transport the welded finished products completed by the second conveying platform 2. The welded finished products on the third conveying platform 8 are placed on the finished product output device 9 by manual labor or a robotic arm. The finished product output device 9 can be a material placement platform, a belt conveyor, or a transmission roller conveyor.
[0039] In addition to the steps described above, the welding method of this embodiment also includes step (5): the second conveying platform 2 conveys the welded finished product to the third conveying platform 8, and then places the welded finished product on the finished product output device 9, and after inspection, it is transferred to the warehouse.
[0040] This invention enables semi-automated batch welding of "steel mesh truss formwork without dismantling" components for three-dimensional structures at a lower cost. The equipment has a simple structure, stable and uniform welding quality, and high production efficiency, which is conducive to the promotion and use of wall panels for prefabricated buildings.
[0041] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
