Description

Technical Field

[0001] This invention relates to the field of building steel-wood keel processing, and more particularly to a building steel-wood keel recycling and preparation system. Background Technology

[0002] Concrete is widely used in building construction. During the construction of cast-in-place concrete structures, joists and secondary joists play crucial roles in supporting and maintaining the shape of the concrete, enhancing structural strength and stability, and are used in enormous quantities on-site. Taking residential construction projects, which are the most convenient for relocation and multiple uses, as an example, approximately 100,000 to 140,000 meters of joists are used per 10,000 square meters of building area, with dozens of different specifications. Other types of projects generally use even more joists. Currently, the main types of joists used in concrete support systems in the construction industry are: traditional solid wood joists, steel-wood joists, and composite material joists. Among them, steel-wood joists are increasingly widely used due to their excellent comprehensive performance and compliance with environmental protection principles. For details on steel-wood joists, please refer to patent application number CN202021961453.8, entitled "A Steel-Wood Joist for Construction."

[0003] During project implementation, the keel structure is typically assembled with nails and formwork. It bears significant loads and is in direct contact with the concrete during pouring. After concrete pouring, the keel structure needs to be dismantled for reuse. The dismantled keels often have issues such as cement residue, nail attachments, and bending, requiring maintenance. Furthermore, the dismantled keels are often of various sizes and require sorting and classification during later reuse, storage, and transportation. Currently, the sorting, nail removal, straightening, and transportation of keels mainly rely on manual labor. Manually comparing lines drawn on the ground is prone to errors, leading to misclassification. Moreover, steel-wood keels consist of a steel outer keel and a wooden inner keel running through it, resulting in a large overall weight. The manual recycling process is labor-intensive, inefficient, and costly. Additionally, residual steel nails, protruding iron plates, and splinters on the steel-wood keels pose potential hazards, easily causing injury to workers during handling and transportation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a building steel and wood keel recycling and preparation system, which effectively solves the problems of high labor intensity, low work efficiency and high labor cost of pure manual recycling.

[0005] This invention is achieved through the following technical solution:

Due to the high degree of automation of this invention, the involvement of workers is greatly reduced, thereby effectively improving the safety of workers during construction. Compared with the existing method of manually comparing lines drawn on the ground with the eyes, which is prone to errors and resulting in classification errors, the steel-wood keel is sorted and temporarily stored by the sorting mechanism 5 based on the length data, which effectively improves the sorting accuracy.

[0056] Processing procedures for recycling and preparing building steel and wood framing:

[0057] Step 1: The feeding line 9 carries the building steel and wood keel from the stacking platform to the workbench 10. The staff can perform a preliminary inspection of the building steel and wood keel on the workbench 10. The building steel and wood keel that meets the preliminary inspection requirements is placed on the conveyor line 7. The conveyor line 7 transports the building steel and wood keel along the Y direction. The staff can use the nail pullers 13 suspended on the portal frame 12 to remove the steel nails that are easy to remove from the building steel and wood keel.

[0058] Step 2: The conveyor line 7 feeds the building steel and wood keel into the straightening mechanism 2, and the multiple sets of straightening rollers 14 of the straightening mechanism 2 cooperate to straighten the building steel and wood keel.

[0059] Step 3: The building steel and wood keel enters the cleaning mechanism 3. The multiple sets of steel wire rollers of the cleaning mechanism 3 work together to clean the surface of the building steel and wood keel. The cleaning chamber 16 is used to collect the waste after the surface treatment of the building steel and wood keel.

[0060] Step 4: The re-inspection conveyor platform 17 conveys the building steel and wood keel one by one along the conveying direction perpendicular to the conveyor line 7. The lifting component 18 moves the building steel and wood keel up to the measuring component 19.

[0061] The photoelectric sensor is used to sense the steel and wood keel of the building and to detect both ends of the steel and wood keel. The built-in algorithm module calculates the length of the steel and wood keel in real time based on the conveying speed of the transmission unit and the sensing time of the photoelectric sensor, which is then used for the subsequent 5-category sorting by the sorting mechanism.

[0062] The time interval between the photoelectric sensors at both ends of the building steel-wood keel is time T, and the speed at which the transmission unit drives the building steel-wood keel is V.

[0063] L=V*T;

[0064] Then, the length value L of the building steel-wood keel is obtained;

[0065] Step 5: The sorting mechanism 5 is used to sort and temporarily store the building steel and wood keel with measured length data. In this embodiment, the sorting mechanism 5 includes multiple sorting components. The sorting components include a sorting line 22 and two sorting racks 23.

The sorting unit includes an electric guide plate 26, a winding line 27, and a storage platform 28.

[0066] Step 5.1 When the building steel and wood keel needs to be sorted to the sorting unit located on the top side, the uppermost electric guide plate 26 is adjusted to the tilt angle. At this time, under the push of the opposing cylinder unit 25, the building steel and wood keel falls onto the uppermost gathering line 27, and the gathering line 27 moves the building steel and wood keel to the storage platform 28.

[0067] Step 5.2: When the building steel and wood keel needs to be sorted to the sorting unit in the middle layer, the uppermost electric guide plate 26 is adjusted to a vertical state, while the middle electric guide plate 26 is adjusted to an inclined state. At this time, under the push of the opposing cylinder unit 25, the building steel and wood keel passes through the upper sorting unit and falls onto the middle layer gathering line 27. The middle layer gathering line 27 moves the building steel and wood keel horizontally onto the shelf 28, thus realizing the sorting of the building steel and wood keel.

[0068] Step 5.3 Similarly, when the building steel and wood keel needs to be sorted to the sorting unit at the bottom, execute the same instructions as in step 5.2.

[0069] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
