Moreover, most of the existing support frames are designed for specific panel sizes and are difficult to adapt to the installation requirements of different specifications of formwork and insulation integrated panels, with insufficient versatility.

Detailed implementation manners

[0025] As Figures 1 - 6 shown, an adjustable fixed formwork integrated plate frame body includes a plurality of lower cross beams 1 and a plurality of upper cross beams 2 arranged in parallel corresponding to each of the lower cross beams 1 one by one. A level adjustment mechanism is provided at the bottom of each of the lower cross beams 1, and an adjustable connection mechanism for the cross beam is provided between each adjacent two of the lower cross beams 1 and between each adjacent two of the upper cross beams 2 respectively.

[0026] A plurality of lower columns 3 perpendicular to each of the lower cross beams 1 are fixedly arranged at the upper part of each of the lower cross beams 1 at equal intervals, and a plurality of upper columns 4 corresponding to each of the lower columns 3 one by one are fixedly arranged at the lower part of each of the upper cross beams 2 at equal intervals. A plurality of through holes for tie bolts 5 are respectively formed at equal intervals on each of the upper columns 4 and each of the lower columns 3, and an adjustable connection mechanism for the column is provided between each pair of opposite lower columns 3 and upper columns 4.

[0027] In this embodiment, each of the lower cross beams 1, upper cross beams 2, lower columns 3 and upper columns 4 is of square steel structure.

[0028] As Figure 3 shown, each of the level adjusting mechanisms includes two substrates 6 symmetrically arranged below the lower cross beam 1 and fixedly anchored to the ground. Each of the substrates 6 is fixedly provided with a threaded sleeve 7, and each of the threaded sleeves 7 is provided with an adjusting screw rod 8 threadedly connected thereto. The upper end of the adjusting screw rod 8 is rotatably connected to the bottom of the lower cross beam 1. Specifically: the bottom of the lower cross beam 1 is symmetrically and fixedly provided with a connecting head 9 with a T-shaped vertical cross section, and the horizontal cross section of each part of the connecting head 9 is circular. The upper end surface of the adjusting screw rod 8 is sequentially provided with a small-diameter connecting hole and a large-diameter connecting hole from top to bottom. The upper end of the connecting head 9 is rotatably matched with the small-diameter connecting hole, and the lower end of the connecting head 9 is rotatably matched with the large-diameter connecting hole.

[0029] Two rotating handles 10 are symmetrically and fixedly provided on the outer peripheral wall of the adjusting screw rod 8 near the upper end. In addition, a bubble level 11 is provided on the outer side of each of the lower cross beams 1.

[0030] During the construction of this embodiment, the height difference between the two ends of the lower cross beam is determined according to the display of the bubble level, and then the adjusting screw rod is rotated by operating the rotating handle. During the rotation of the adjusting screw rod, the distance between the bottom of the lower cross beam and the corresponding substrate can be changed through axial movement, so as to effectively adjust the levelness of the lower cross beam and the entire frame body, avoid problems such as staggered platforms and uneven gaps after the subsequent installation of the formwork integrated board, and is beneficial to ensuring the construction quality and aesthetics.

[0031] As Figures 4 - 5As shown in the figure, each of the crossbeam adjustable connection mechanisms includes a connecting crossbeam 12. One end of the connecting crossbeam 12 located between two adjacent lower crossbeams 1 is fixedly connected to the end of one of the lower crossbeams 1, and the other end is movably inserted and fitted with the other lower crossbeam 1. On both sides of the lower crossbeam 1 that is inserted and fitted with the connecting crossbeam 12, a plurality of pairs of crossbeam limiting through holes 13 are symmetrically arranged at equal intervals. An upper part of one end of the connecting crossbeam 12 close to the lower crossbeam 1 fixedly connected thereto is provided with a sliding groove 14 along its width direction. Two adjusting brackets 15 with an L-shaped cross-section are symmetrically and slidably arranged in the sliding groove 14, and the vertical parts of each adjusting bracket 15 are slidably fitted with the sliding groove 14. A horizontal first guide rod 16 is fixedly arranged in the middle of the interior of the connecting crossbeam 12. A through hole that is in clearance fit with the first guide rod 16 is opened in the middle of the horizontal parts of the two adjusting brackets 15. A first spring 17 is sleeved on the part of the first guide rod 16 located between the two adjusting brackets 15. One first limiting steel ball 18 that is adapted to the crossbeam limiting through hole 13 is fixedly connected to each side of the free ends of the horizontal parts of the two adjusting brackets 15 that face away from each other; the connecting crossbeam 12 is respectively provided with crossbeam through holes 19 at positions corresponding to the two first limiting steel balls 18, and the inner diameter of each crossbeam through hole 19 is larger than the outer diameter of the first limiting steel ball 18.

[0032] In this embodiment, the distance between two lower crossbeams is adjusted by the connecting crossbeam. Specifically, after the connecting crossbeam is fixedly welded to one of the lower crossbeams, the staff relatively presses the free ends of the vertical parts of the two adjusting brackets to insert the other end of the connecting crossbeam into the interior of the other lower crossbeam. The distance that the connecting crossbeam is inserted into the lower crossbeam is adjusted according to the length specification of the formwork integrated board. After the position is reached, the acting force on the two adjusting brackets is released, and under the action of the first spring, the two adjusting brackets drive the two first limiting steel balls to move away from each other. The two first limiting steel balls are engaged with the crossbeam limiting through holes at the corresponding positions of the lower crossbeam, so as to realize the fixed connection between the connecting crossbeam and the other lower crossbeam.

[0033] Similarly, in this embodiment, one end of the connecting crossbeam 12 located between two adjacent upper crossbeams 2 is fixedly connected to the end of one of the upper crossbeams 2, and the other end is movably inserted and fitted with the other upper crossbeam 2. On both sides of the upper crossbeam 2 that is inserted and fitted with the connecting crossbeam 12, a plurality of pairs of the crossbeam limiting through holes 13 are symmetrically arranged at equal intervals. The connection mode of the connecting crossbeam 12 connecting two adjacent upper crossbeams is the same as the mode of connecting two lower crossbeams, and this specification will not elaborate further.

[0034] In addition, as a further improvement of this embodiment, two connecting plates 20 are symmetrically and fixedly arranged at both ends of the sliding groove 14 on the upper part of the connecting cross beam 12. An connecting rod 21 is fixedly arranged between the two connecting plates 20. Through holes which are in clearance fit with the connecting rod 21 are respectively formed at positions near the upper ends of the vertical parts of the two adjusting frames 15. External threads are formed on the peripheral wall of the connecting rod 21, and two first nuts 22 which are in threaded connection with the connecting rod 21 are installed at positions between the two adjusting frames 15. After the two adjusting frames 15 are reset under the action of the first spring, the two adjusting frames 15 are locked and fixed by screwing the two first nuts 22 respectively towards the two adjusting frames 15, so as to avoid the loosening of the position of the cross beam adjustable connecting mechanism during the construction process.

[0035] As Figure 6 shown, each column adjustable connecting mechanism includes a connecting column 23. The upper ends of the connecting columns 23 are fixedly connected to the lower ends of the corresponding upper columns 4, and the lower ends of the connecting columns 23 are movably inserted and matched with the upper ends of the corresponding lower columns 3. A plurality of pairs of column limiting through holes 24 are symmetrically and evenly spaced on both sides of the upper part of the lower column 3. The axes of the column limiting through holes 24 are perpendicular to the axis of the tension bolt hole 5. Two shift rods 25 are symmetrically and slidably arranged at positions near the upper end of the connecting column 23. One ends of the two shift rods 25 located inside the connecting column 23 are respectively fixedly connected to the upper ends of two vertical adjusting rods 26. A horizontal second guide rod 27 is fixedly arranged in the middle of the connecting column 23. Through holes which are in sliding fit with the second guide rod 27 are formed in the middle parts of the two adjusting rods 26. A second spring 28 is sleeved on the second guide rod 27 at a position between the two adjusting rods 26. Second limiting steel balls 29 which are adapted to the column limiting through holes 24 are respectively fixedly connected to the sides of the lower ends of the two adjusting rods 26 which face away from each other. Column through holes 30 with an inner diameter larger than the outer diameter of the second limiting steel balls 29 are respectively formed in the connecting column 23 at positions corresponding to the two second limiting steel balls 29, and tension bolt through holes 31 which are parallel to the axis of the tension bolt hole 5 and have the same specification are evenly spaced on the connecting column 23.

[0036] In this embodiment, the distance between the corresponding lower column and upper column is adjusted by connecting columns. Specifically, after the connecting column is fixedly welded to the upper cross beam, the staff inserts the lower end of the connecting column into the interior of the lower column by relatively pressing the free ends of the two lever rods. The distance that the connecting column is inserted into the lower column is adjusted according to the height specification of the formwork integrated board. After reaching the position, the acting force on the two lever rods is released, and under the action of the second spring, the two adjusting rods drive the two second limiting steel balls to move away from each other. The two second limiting steel balls are engaged with the column limiting through holes at the corresponding positions of the lower column, so as to realize the fixed connection between the upper column and the lower column.

[0037] In addition, as a further improvement to this example, two guide sleeves 32 that are symmetrically and fixedly arranged at the upper end of the connecting column 23 and are respectively slidably matched with the two lever rods 25 are provided. At one end of each of the two lever rods 25 located outside the connecting column 23, a limiting head 33 is fixedly arranged, and the outer diameter of the limiting head 33 is greater than the inner diameter of the guide sleeve 32. External threads are provided on the peripheral wall of each lever rod 25, and a second nut 34 that is threadedly connected thereto is installed at a position between the limiting head 33 and the guide sleeve 32. After the two adjusting rods are reset under the action of the second spring, the second nuts on each lever rod 25 can be screwed towards the position of the guide sleeve 32 to effectively lock the lever rods 25, avoiding the loosening of the position of the column adjustable connection mechanism during the construction process.

[0038] After the entire frame is adjusted and fixed, the through tension bolts can pass through the pre-formed through holes for tension bolts and the through holes for tension bolts and be fixedly tied to the inner formwork integrated board.

[0039] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention.
