Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a storage and transportation frame for vertical prefabricated exterior wall panels and a hoisting method thereof. Background Technology

[0002] In prefabricated building structures, after the prefabricated exterior wall panels are manufactured in the factory, they need to be stored and transported to the construction site.

[0003] Currently, the common storage method is to temporarily store prefabricated exterior wall panels in a maintenance area after production, using a gantry crane. The panels are secured with clamps and inserts using fixed mounting frames. When space in the temporary storage area is insufficient, the panels need to be lifted inwards, one by one, and fixed onto the transport frame of an inward-lifting vehicle. The inward-lifting vehicle then transports the panels to a freight yard, where they are unloaded and stored. At the construction site, the panels are lifted out of the freight yard, fixed onto the transport frame of a transport vehicle, and then unloaded into the temporary storage area. On average, a single wall panel requires six lifting and placement operations from the production line to the construction site.

[0004] To improve operational efficiency and reduce the number of times prefabricated exterior wall panels are repeatedly lifted and placed, a method for hoisting and transporting vertical prefabricated exterior wall panels as a whole is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the deficiencies of existing technologies and provide a storage and transportation frame and method for hoisting vertical prefabricated exterior wall panels.

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.

[0021] like Figure 1-7 As shown, a vertical prefabricated exterior wall panel storage and transportation frame for overall hoisting includes a frame 100, a base 200, an operating platform 300, a ladder 400, and a placement limiting body 500.

The placement limiting body 500 is installed inside the frame 100, and the prefabricated exterior wall panel 600 is placed on the base 200 inside the frame 100 and rests against the placement limiting body 500.

[0022] The frame 100, serving as the load-bearing skeleton of the entire storage and transport frame, is made of high-strength steel and includes four side posts 101, four long side crossbars 102, four short side crossbars 103, four vertical bars 104, four diagonal bars 105, and two horizontal bars 106. The four side posts 101 are vertically arranged and formed by steel, creating the four corner supports of the rectangular frame. The bottom of the four side posts 101 is connected by two long side crossbars 102 and two short side crossbars 103 to form a rectangular base, while the top is connected by another two long side crossbars 102 and two diagonal bars 106.

The two upper crossbeams 303 are arranged at the top of the frame 100, and their two ends are fixedly connected to the top short side crossbeams 103. The four uprights 301 are arranged vertically and are fixedly connected to the upper crossbeams 303 and lower crossbeams 302 respectively. The panel 304 is installed on the surface of the two upper crossbeams 303 to form an operating surface. The guardrails 305 are fixed along the long side to the upper surface of the upper crossbeams to effectively prevent operators from falling. The diagonal brace 306 is made of angle steel, with one end welded to the column 301 and the other end welded to the upper crossbeam 303 to enhance the stability of the operating platform frame.

[0025] The ladder 400 is used for operators to go up and down the operating platform. It includes a ladder upright 401, a ladder cross brace 402, and a connecting rod 403. The ladder upright 401 is arranged vertically, and its upper and lower ends are fixedly connected to the short side cross brace 103 respectively. The connecting rod 403 connects the ladder upright 401 and the side column 101 into a whole. The ladder cross brace 402 is fixed at intervals to the ladder upright 401 to form a passage for operators to go up and down.

[0026] The placement limiting body 500 includes an outer placement limiting device 510, a middle placement limiting device 520, and an inner placement limiting device 530, which are used to limit and fix the prefabricated exterior wall panel 600 to prevent it from shifting or tipping over during storage and transportation.

[0027] The outer side placement limiting device 510 includes a horizontal square timber 511 and a vertical square timber 512. The horizontal square timber 511 is fixed to the long side horizontal bar 102 on the top surface of the frame 100 in sections by screws, and the vertical square timber 512 is fixed to the vertical bar 104 on the side of the frame 100 by screws. The intermediate positioning and limiting device 520 includes a full-length horizontal bar 521, two full-length steel plates 522, four short vertical bars 523, two horizontal square timbers, and two vertical square timbers. The full-length horizontal bar 521 is arranged horizontally, and the two ends of the two full-length horizontal bars 521 are fixedly connected to the connecting rods 403 respectively. The short vertical bars 523 are arranged vertically, and the bottom of the short vertical bars 523 is fixedly connected to the horizontal bar 106 at the bottom of the frame 100. The top of the short vertical bars 523 is fixedly connected to the bottom of the full-length horizontal bar 521. The two full-length steel plates 522 and the top surface of the full-length horizontal bar 521 form a triangle and are fixedly connected by welding. The two horizontal square timbers are fixed to the full-length horizontal bar 521 in sections by screws, and the two vertical square timbers are fixed to the short vertical bars 523 by screws. The inner side placement limiting device 530 includes three horizontal square timbers and three vertical square timbers. The three horizontal square timbers are fixed to the upper crossbeam 303 of the operating platform 300 in sections by screws, and the three vertical square timbers are fixed to the column 301 of the operating platform 300 by screws.

[0028] like Figure 8 As shown, the first horizontal timber 511 passes through the long side crossbar 102 on the top surface of the frame 100 with a screw and is fixed by tightening the screws at both ends; the second horizontal timber passes through the continuous crossbar 521 with a screw and is fixed by tightening the screws at both ends; the third horizontal timber passes through the upper crossbeam 303 of the operating platform 300 with a screw and is fixed by tightening the screws at both ends; the upper parts of the first horizontal timber 511, the second horizontal timber, and the third horizontal timber are all cut at bevels, and the bevel is consistent with the bevel of the triangular structure formed by the continuous steel plate 522.

[0029] like Figure 9 As shown, the first vertical timber 512 passes through the vertical rod 104 of the frame 100 with a screw and is fixed by tightening the screws at both ends; the second vertical timber passes through the short vertical rod 523 with a screw and is fixed by tightening the screws at both ends; the third vertical timber passes through the column 301 of the operating platform 300 with a screw and is fixed by tightening the screws at both ends; the upper parts of the first vertical timber 512, the second vertical timber, and the third vertical timber are all cut at an angle, and the angle is consistent with the angle of the first horizontal timber 511, the second horizontal timber, and the third horizontal timber.

[0030] like Figure 10 As shown, a lifting lug 700 is fixedly connected to the upper side wall of the side column 101. The lifting lug 700 is made of steel plate and the surface is treated with rust removal and anti-corrosion for overall lifting. A stiffening plate 800 is fixedly connected at the connection position between the side column 101 and the short side crossbar 103. The stiffening plate 800 is a rectangular steel plate with a thickness of not less than 10mm, which can effectively enhance the load-bearing strength of the connection and avoid stress concentration.

[0031] A method for hoisting prefabricated exterior wall panels as a whole includes the following steps: Step a: First, check whether the connections of each component of the storage and transport frame are secure, whether the rubber strip 202 is intact, and whether the lifting lug 700 is damaged; then, use a gantry crane or hoist to lift the precast exterior wall panel 600, keeping it vertical during the lifting process to avoid tilting; place the interior side of the precast exterior wall panel 600 against the continuous steel plate 522 of the middle support limiting device 520 and the horizontal square timber, and slowly lower the precast exterior wall panel 600 down the 30° slope. During the lowering process, arrange for operators to climb the ladder 400 onto the operating platform 300, and use the outer support limiting device 510 and the inner support limiting device 530 for auxiliary limiting to ensure that the precast exterior wall panel 600 is accurately lowered. Finally, the bottom surface of the precast exterior wall panel 600 lands stably on the rubber strip 202 of the base 200.

[0032] Step b: Fill the storage and transport frame. Repeat the operation of step a, placing the prefabricated exterior wall panels 600 one by one into the storage and transport frame, maintaining an appropriate distance between adjacent prefabricated exterior wall panels 600 to avoid mutual compression, until the entire hoisting vertical prefabricated exterior wall panel storage and transport frame is filled. In this embodiment, each storage and transport frame can hold 6-8 prefabricated exterior wall panels 600.

[0033] Step c: Overall hoisting and loading. Use the hook of a gantry crane or hoist to hook the lifting lug 700 on the side column 101 of the storage and transport frame. After checking that the connection between the hook and the lifting lug 700 is reliable, hoist the entire vertical precast exterior wall panel storage and transport frame onto the transport vehicle in one go. Use steel wire ropes or special buckles to fix the bottom of the storage and transport frame to the transport vehicle to prevent shaking during transportation. According to the load-bearing capacity and dimensions of the transport vehicle, distribute multiple sets of storage and transport frames evenly on the transport vehicle, maintaining a 100mm gap between adjacent storage and transport frames, until the transport vehicle is fully loaded.

[0034] Step d: Transfer, unloading, and storage. Transfer the precast exterior wall panels 600 to the freight yard or construction site. Control the vehicle speed during transportation to avoid sudden acceleration and braking. Upon arrival at the destination, use a gantry crane or hoist to lift the vertical precast exterior wall panel storage and transport frames one by one using the lifting lugs 700. Keep the storage and transport frames stable during the lifting process. After removing the steel wire ropes or special buckles used for transportation fixation, lift the storage and transport frames to the pre-designated storage area in the freight yard or construction site. Use expansion bolts to fix the bottom of the storage and transport frames to the ground to prevent them from tipping over during storage.

[0035] 1. Achieving vertical storage and overall hoisting, reducing component damage: This invention adopts a vertical storage method, avoiding the deformation problem caused by flat stacking of prefabricated exterior wall panels; the base is equipped with rubber strips, which can effectively buffer and support, protecting the bottom surface of the prefabricated exterior wall panels; the horizontal and vertical square timbers of the support limiter are all set with bevels, and the bevel is consistent with the bevel of the triangular structure of the continuous steel plate, ensuring the stability of the prefabricated exterior wall panels when placed against the ground. At the same time, the material of the square timber can avoid wear on the surface of the components. With the triple limiter on the outer, middle and inner sides, collisions and tipping of components are prevented during storage and transportation, greatly reducing the component damage rate.

[0036] 2. Improve hoisting and transportation efficiency: By setting lifting lugs on the side columns of the frame, the entire storage and transportation frame can be hoisted, eliminating the need for multiple hoisting of individual prefabricated exterior wall panels, which greatly shortens the loading and unloading time; during transportation, multiple sets of storage and transportation frames can be evenly distributed on the transport vehicle to achieve batch transportation, significantly improving transportation efficiency and reducing transportation costs.

[0037] 3. Stable structure and high safety: The frame adopts a frame structure composed of side columns, long side crossbars, short side crossbars, vertical bars, diagonal bars and horizontal bars, which has high overall rigidity and strong load-bearing capacity; stiffening plates are set at the connection between the side columns and the short side crossbars to further enhance the connection strength; the operating platform is equipped with guardrails, which, together with the ladder, form a safe working passage, which facilitates the operation of components placement, inspection and other operations, and ensures the safety of operation.

[0038] 4. High versatility and convenient installation: The horizontal and vertical square timbers supporting the limiting body are fixed in sections by screws at intervals. The fixing position of the screws can be adjusted according to the size of different specifications of prefabricated exterior wall panels, so as to adapt to the storage needs of prefabricated exterior wall panels of different widths and heights. Most of the components are fixed by screws or welded together, which makes installation and disassembly convenient, and facilitates maintenance and turnover.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
