[0026] The present invention installs two rails 4 in parallel on the connecting steel pipe 1 of the formwork frame through fasteners 2, and cooperates with the longitudinal square tube 11 and the transverse square tube 12 thereon by four rectangularly distributed adjustment columns 6, and the panel 7 as a transportation platform for carrying materials. The vertically adjustable height adjustment columns 6 can synchronously adjust the use height of the four adjustment columns 6 as needed, and the transverse use width of the rectangular frame can be adjusted as needed by the transverse square tube 12 with transversely adjustable length, and panels 7 of different sizes can be selected for laying and installation as needed, which can conveniently meet the loading and transportation of materials of different quantities or sizes, and solve the problem of inconvenient material transportation in the formwork frame.

[0027] The present invention provides a second supporting telescopic oblique rod 9 with two hinged ends and an inverted "V" shape. When the column 6 is adjusted, the inverted "V"-shaped tips of the two second supporting telescopic oblique rods 9 can be adjusted by adjusting the use length of the two second supporting telescopic oblique rods 9. The provision of the first supporting telescopic oblique rod 8 with two hinged ends and an inverted "V" shape can adapt to the adjustment of the adjusting column 6 and the adjustment of the horizontal square tube 12 with adjustable length laterally, so that the two first supporting telescopic oblique rods 8 can always be pressed against the lower end of the horizontal square tube 12.

[0028] In this solution, the above-mentioned connecting steel pipe 1 is an actual internal formwork set up at the construction site. A fastener 2 is provided on the connecting steel pipe 1, and the track 4 is placed on the fastener 2. The track 4 is tightened and fixed by the fastening screw 3 on the side of the fastener 2 to achieve relative fixation of the connecting steel pipe 1 and the track 4. When in use, the panel 7 can also be fixed to the upper end of the adjustment column 6 as needed using a vertical fastening screw. In this solution, the above-mentioned second supporting telescopic diagonal rod 9 and the first supporting telescopic diagonal rod 8 can also use electric or pneumatic telescopic rods. In this solution, the longitudinal square tube 11 and the transverse square tube 12 can be installed on the upper end side of the adjustment column 6, and cooperate with the upper end face of the adjustment column 6 to jointly support the panel 7. Vertical connecting bolts can also be provided between the panel 7 and the upper end of the adjustment column 6 as needed for reinforcement. In actual application, the panel 7 can be selected according to the material volume.

[0029] As attached Figure 2As shown, in another specific embodiment based on the above, the adjusting column 6 includes an upper threaded sleeve 61, a lower threaded sleeve 63 and an adjusting screw 64. The lower threaded sleeve 63 is vertically installed on the sliding assembly 5. A vertical lower threaded hole is opened at the center of the upper end of the lower threaded sleeve 63. The adjusting screw 64 is threadedly connected in the lower threaded hole. A vertical upper threaded hole with a thread opposite to the lower threaded hole is opened at the center of the lower end of the upper threaded sleeve 61. The upper end of the adjusting screw 64 is threadedly connected in the upper threaded hole. The adjusting screw 64 is used to rotate and synchronously drive the upper threaded sleeve 61 and the lower threaded sleeve 63 to move close or apart.

[0030] Wherein, an adjusting nut 62 is fixedly connected to the adjusting screw rod 64 between the upper threaded sleeve 61 and the lower threaded sleeve 63. In this way, the adjusting screw rod 64 can be easily driven to rotate by the adjusting nut 62.

[0031] The ends of the two second telescopic supporting diagonal rods 9 are hinged on the upper threaded sleeve 61, and the ends of the two first telescopic supporting diagonal rods 8 are hinged on the upper threaded sleeve 61. In this way, when in use, the second telescopic supporting diagonal rods 9 and the first telescopic supporting diagonal rods 8 are not affected by the height adjustment of the adjustment column 6, thereby increasing the convenience and stability of the device when in use.

[0032] As attached Figure 3 As shown, in a specific embodiment based on the above, the second supporting telescopic oblique rod 9 includes a second sleeve 91 and two second screws 92. The second sleeve 91 is provided with two sections of symmetrical and coaxial internal threads, and the thread directions of the two sections of internal threads are opposite. The two second screws 92 are respectively screwed into the second sleeve 91 from both ends. One second screw 92 extends out of the end of the second sleeve 91 for being hinged on the adjusting column 6, and the other second screw 92 extends out of the end of the second sleeve 91 for being hinged with the second screw 92 of the other second supporting telescopic oblique rod 9. The second sleeve 91 is used to rotate and drive the second screws 92 at both ends to extend or retract synchronously.

[0033] In a specific embodiment based on the above, the first supporting telescopic oblique rod 8 includes a first sleeve 81 and two first screws 82. The first sleeve 81 is provided with two symmetrical and coaxial internal threads, and the thread directions of the two sections of internal threads are opposite. The two first screws 82 are respectively screwed into the first sleeve 81 from both ends. One first screw 82 extends out of the end of the first sleeve 81 for being hinged on the adjusting column 6, and the other first screw 82 extends out of the end of the first sleeve 81 for being hinged with the first screw 82 of the other first supporting telescopic oblique rod 8. The first sleeve 81 is used to rotate and drive the first screws 82 at both ends to extend or retract synchronously.

[0034] In the above solution, the ends of the second screw rod 92 and the first screw rod 82 can be mounted on the adjustment column 6 via hinged ear plates.

[0035] In a specific embodiment based on the above, the transverse square tube 12 includes a transverse outer rod 121 and a transverse inner rod 122. The upper ends of the two adjustment posts 6 are connected to one end of the transverse outer rod 121 and the transverse inner rod 122, respectively. The other ends of the transverse outer rod 121 and the transverse inner rod 122 are slidably connected to each other. In this embodiment, a plurality of spaced connection holes can be provided between the transverse outer rod 121 and the transverse inner rod 122 as needed. After the relative positions of the transverse outer rod 121 and the transverse inner rod 122 are adjusted, bolts can be inserted into the connection holes to limit and fix them.

[0036] In one embodiment based on the above, a transverse square tube 12 is connected between the two longitudinal square tubes 11 and in the middle of the longitudinal square tubes 11. Thus, the additional transverse square tube 12 can increase the stability of the rectangular frame structure formed by the longitudinal square tubes 11 and the transverse square tubes 12 for supporting the panel 7.

[0037] In a specific embodiment based on the above, a connecting angle steel 10 is installed on the upper side wall of the adjustment column 6. The connecting angle steel 10 is used to support the lower end of the end of the longitudinal square tube 11 or the transverse square tube 12. In this solution, the connecting angle steel 10 can facilitate the loading and installation of the longitudinal square tube 11 or the transverse square tube 12, while also increasing the stability of the connection between the longitudinal square tube 11 or the transverse square tube 12. During use, the end of the longitudinal square tube 11 or the transverse square tube 12 can also be reinforced with the connecting angle steel 10 via vertical fastening screws.

[0038] In a specific embodiment based on the above, the sliding assembly 5 includes a mounting plate 51, a connecting plate 52, and a pulley 53. A track groove with a "convex" cross-section is defined within the track 4. The connecting plate 52 is vertically inserted into the track groove from the upper end opening of the "convex" track groove. The pulleys 53 are mounted on both sides of the connecting plate 52 and embedded in the inner recess of the "convex" track groove. The upper end of the connecting plate 52 is connected to the adjustment column 6 via the mounting plate 51. In this way, the pulleys 53 embedded in the inner recess of the "convex" track groove provide convenience of movement. At the same time, the embedded arrangement can increase the stability of the pulleys 53.

[0039] A specific embodiment of the present invention is as follows:

[0040] Slide Rail Assembly: Determine the position of track 4 and the width between tracks based on the actual width of the inner formwork on site. Locate connecting steel pipe 1 on the inner formwork at the transport location and connect it to the connecting steel pipe 1 using fasteners 2. Once connected, place track 4 on fasteners 2 and tighten fasteners 2 to the sides of track 4 using screws 3.

[0041] Assembly of the platform part: After the assembly of the slide rail part is completed, place the pulley 53 and other structures in the track 4 from the end opening of the track groove of the track 4, weld and fix the adjustment column 6 to the mounting plate 51, and synchronously adjust the four adjustment columns 6 until they all reach the specified height, and install the longitudinal square tube 11 and transverse square tube 12 of the required length accordingly. After that, rotate the first sleeve 81 accordingly until the two first supporting telescopic diagonal rods 8 are hinged and pressed against the lower end of the transverse square tube 12, and rotate the second sleeve 91 accordingly until the two second supporting telescopic diagonal rods 9 are hinged and pressed against the lower end of the longitudinal square tube 11, and then install the panel 7 of the required size.

[0042] During adjustment, the hinges of the two first supporting telescopic diagonal rods 8 can drive one of the first supporting telescopic diagonal rods 8 to extend as needed, and the other one to shorten accordingly, so as to press against different positions of the lower end of the horizontal square tube 12 as needed. The two second supporting telescopic diagonal rods 9 can also perform the same operation to increase the adjustability of the device structure and improve the stability of the device during support according to the loading conditions of different materials.

[0043] After the materials are loaded, the panel 7 and the materials are moved along the track 4 to the designated position.
