[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example

[0028] A structural plate formwork device includes an upper structural plate 1 and a lower structural plate 2. The upper structural plate 1 and the lower structural plate 2 are connected by a support frame 5, and the support frame 5 can support the upper structural plate 1.

[0029] like Figure 1-Figure 5As shown, in this embodiment: the end of the lower structural plate 2 is connected to the cantilever 3, the cantilever 3 is slidably connected to the support plate 4, and the support plate 4 is used to support part of the support frame 5; the effect achieved by the above components is: when the length of the upper structural plate 1 is greater than the lower structural plate 2, and the support frame 5 cannot be completely installed on the lower structural plate 2, the cantilever 3 is set at the end of the lower structural plate 2, and the support plate 4 on the cantilever 3 can provide support for the support frame 5. Not only is the structure simple and easy to connect, but it can also effectively solve the problem of different lengths of the upper and lower structural plates, which makes it difficult to support the formwork and pouring.

[0030] like Figure 1-Figure 5 As shown, in this embodiment: a telescopic cavity 31 is opened on the side of the cantilever 3, the extension direction of the telescopic cavity 31 is parallel to the plane of the lower structural plate 2, and the support plate 4 is slidably connected in the telescopic cavity 31; the effect achieved by the above components is: when the length difference between the upper structural plate 1 and the lower structural plate 2 is too large, the position of the support plate 4 can be moved to provide support for the support frame 5.

[0031] like Figure 1-Figure 5 As shown, in this embodiment: the support plate 4 is located on one side of the cantilever 3 and is provided with a plurality of through holes 41, and a positioning rod 32 is inserted into the top surface of the cantilever 3, and the positioning rod 32 passes through any through hole 41 to fix the support plate 4 to the cantilever 3. The effect achieved by the above components is: when the support plate 4 is moved to the appropriate position, the positioning rod 32 passes through the corresponding through hole 41, and the support plate 4 can be fixed to the cantilever 3.

[0032] If the positioning function of the positioning rod 32 is relied upon alone, it is difficult to maintain the stability of the support plate 4 , and the support plate 4 may not be sufficient to withstand the pressure of the support frame 5 . Therefore, another supporting structure needs to be provided below the support plate 4 .

[0033] like Figure 1-Figure 5 As shown, in this embodiment: the supporting structure below the support plate 4 includes a diagonal support structure 7 connected between the side surface of the cantilever 3 and the bottom surface of the support plate 4, and a diagonal structure 8 connected between the diagonal support structure 7 and the side surface of the cantilever 3. The diagonal support structure 7 can provide support for the bottom surface of the support plate 4, and the force exerted on the support plate 4 can be transmitted to the side surface of the cantilever 3 through the diagonal support structure 7; accordingly, the diagonal structure 8 can fix the side surface of the diagonal support structure 7 on the side surface of the cantilever 3, which not only increases the stability of the diagonal support structure 7, but also can adjust the inclination angle of the diagonal support structure 7.

[0034] like Figure 1-Figure 5As shown, in this embodiment: the diagonal support structure 7 can be extended and retracted along its length, and both ends are rotatably connected to the cantilever 3 and the support plate 4 through hinges 6; the diagonal support structure 7 includes a diagonal support tube 71, and one end of the diagonal support tube 71 is fixedly connected to a second connecting block 77, and the second connecting block 77 is rotatably connected to the side of the cantilever 3 through the hinge 6; the effect achieved by the above components is: the diagonal support tube 71 is rotatably connected to the side of the cantilever 3 through the second connecting block 77 and the hinge 6.

[0035] like Figure 1-Figure 5 As shown, in this embodiment: a threaded cavity 72 is formed at the other end of the inclined support tube 71, and the extension direction of the threaded cavity 72 is parallel to the length direction of the inclined support tube 71, and a threaded plug rod 73 is threadedly connected. The inclined support tube 71 and the threaded plug rod 73 are both made of high-strength material, and the inclined support tube 71 and the threaded plug rod 73 will not rotate by themselves. During the rotation of the threaded plug rod 73, the effect achieved by the above components is: during the rotation of the threaded plug rod 73 along the threaded cavity 72, the threaded plug rod 73 can be extended and retracted along the extension direction of the threaded cavity 72, because the extension direction of the threaded cavity 72 is parallel to the length direction of the inclined support tube 71, and the threaded plug rod 73 can be extended and retracted in a direction parallel to the length direction of the inclined support tube 71; the inclined support tube 71 and the threaded plug rod 73 are both made of high-strength material, the inclined support tube 71 and the threaded plug rod 73 are high in strength and will not rotate by themselves.

[0036] like Figure 1-Figure 5 As shown, in this embodiment: the free end of the threaded rod 73 is fixedly connected to the rotating cylinder 74, and an inner cavity is opened on the other side of the rotating cylinder 74, and the inner cavity is rotatably connected to the first turntable 75, and the first turntable 75 is clearance-matched with the inner cavity of the rotating cylinder 74. The effect achieved by the above components is: the rotating cylinder 74 and the first turntable 75 are rotatably connected to the rotating cylinder 74, so that the threaded rod 73 can be driven to rotate by rotating the rotating cylinder 74; the first turntable 75 is clearance-matched with the inner cavity of the rotating cylinder 74 to prevent the first turntable 75 from affecting the rotation of the rotating cylinder 74.

[0037] like Figure 1-Figure 5 As shown, in this embodiment: the side of the first turntable 75 away from the threaded rod 73 is fixedly connected to the first connecting block 76, the cross-section of the first turntable 75 is larger than the first connecting block 76, the first connecting block 76 is rotatably connected to the rotating cylinder 74, and the free end is rotatably connected to the bottom surface of the support plate 4 through the hinge 6; the effect achieved by the above components is: the cross-section of the first turntable 75 is larger than the first connecting block 76, which can prevent the rotating cylinder 74 from separating from the first connecting block 76.

[0038] The technical effect achieved by the above-mentioned diagonal bracing structure 7 is that the diagonal bracing structure 7 is a rod-shaped structure as a whole, and its two ends are fixedly connected to the bottom surface of the support plate 4 and the side surface of the cantilever 3 through hinges 6 respectively. In this way, the diagonal bracing structure 7 will form a triangular structure with the support plate 4 and the cantilever 3, so the diagonal bracing structure 7 will have a good supporting effect, and the pressure received by the support plate 4 is transmitted to the cantilever 3 through the diagonal bracing structure 7; in addition, when the support plate 4 is extended and retracted along the telescopic cavity 31, not only the length of the diagonal bracing structure 7 can be extended and retracted, but the inclination angle can also be adjusted through the two hinges 6. Therefore, the diagonal bracing structure 7 can adapt to the extension and retraction of the support plate 4 along the telescopic cavity 31, and can always provide strong support to the support plate 4.

[0039] like Figure 1-Figure 5 As shown, in this embodiment: the inclined structure 8 can be extended and retracted along its length direction, and both ends are rotatably connected to the inclined support structure 7 and the cantilever 3 through the hinge 6. The outer wall of the inclined support tube 71 is fixedly connected to the hinge 6. The inclined structure 8 includes a fourth connecting block 86 connected to the hinge 6 on the outer wall of the inclined support tube 71. The free end of the fourth connecting block 86 is rotatably connected to the inclined tube 81. The fourth connecting block 86 is inserted into the inclined tube 81 and the end thereof is fixedly connected to the second turntable 85. The second turntable 85 is rotatably connected to the inclined tube 81 and has a clearance fit. The cross-sectional area of the second turntable 85 is larger than that of the fourth connecting block 86. The effects achieved by the above components are as follows: the inclined tube 81 can rotate with the outer wall of the inclined support tube 71 through the fourth connecting block 86 and the hinge 6; the inclined tube 81 can rotate with the second turntable 85 and the fourth connecting block 86; the second turntable 85 and the inclined tube 81 are loosely matched, so the second turntable 85 will not hinder the rotation of the inclined tube 81; the cross-sectional area of the second turntable 85 is larger than that of the fourth connecting block 86, so the inclined tube 81 will not separate from the fourth connecting block 86.

[0040] like Figure 1-Figure 5 As shown, in this embodiment: a threaded inner cavity 82 is formed at the end of the inclined tube 81 away from the fourth connecting block 86, the extension direction of the threaded inner cavity 82 is parallel to the length direction of the inclined tube 81, and a threaded rod 83 is threadedly connected. The inclined tube 81 and the threaded rod 83 are both made of high-strength material, and the inclined tube 81 and the threaded rod 83 will not rotate by themselves. The free end of the threaded rod 83 is fixedly connected to the third connecting block 84. The effect achieved by the above components is that the threaded rod 83 can be extended and retracted along the extension direction of the threaded inner cavity 82 during the rotation along the threaded inner cavity 82. Because the extension direction of the threaded inner cavity 82 is parallel to the length direction of the inclined tube 81, the threaded rod 83 can be extended and retracted along the direction parallel to the length direction of the inclined tube 81.

[0041] like Figure 1-Figure 5As shown, in this embodiment: the third connecting block 84 is rotatably connected to the side of the cantilever 3 through the hinge 6, and the threaded rod 83 is extended and retracted along the extension direction of the threaded inner cavity 82 during rotation. The effect achieved by the above components is: during the extension and retraction of the threaded rod 83 along the direction parallel to the length direction of the inclined tube 81, it can be rotatably connected to the side of the cantilever 3 through the third connecting block 84 and the hinge 6, and the inclination angle of the inclined structure 8 can be changed.

[0042] like Figure 1-Figure 5 As shown, in this embodiment: the threaded rod 83 extends and retracts along the extension direction of the threaded inner cavity 82, and drives the diagonal support tube 71 to rotate along the hinge 6 through the diagonal pull tube 81 and the fourth connecting block 86. The height of the hinge 6 connected to the third connecting block 84 is greater than the hinge 6 connected to the second connecting block 77. The effect achieved by the above components is: it can ensure that the diagonal pull structure 8 can provide stable support for the diagonal support structure 7.

[0043] The technical effect achieved by the above-mentioned diagonal structure 8 is that when the inclination angle and position of the diagonal support tube 71 change, the length and inclination angle of the diagonal structure 8 can also change. Therefore, the diagonal structure 8 will not hinder the change of the diagonal support tube 71, but can always provide support to the diagonal support structure 7. The diagonal structure 8 can fix the side of the diagonal support structure 7 on the side of the cantilever 3, which not only increases the stability of the diagonal support structure 7, but also can adjust the inclination angle of the diagonal support structure 7.

[0044] The working process of the utility model is as follows: when the length of the upper structural plate 1 is greater than that of the lower structural plate 2, the support frame 5 is installed on the upper surface of the lower structural plate 2 and the support plate 4 to support the upper structural plate 1;

[0045] When the length of the upper structural plate 1 is too different from that of the lower structural plate 2, first, rotate the inclined tube 81 to extend the length of the inclined tube 81 and the threaded rod 83. At the same time, rotate the rotating tube 74 to extend the length of the rotating tube 74 and the threaded rod 73. During this process, the third connecting block 84, the fourth connecting block 86, the first connecting block 76 and the second connecting block 77 will all have the connected hinges 6 rotated, so that the length of the diagonal support structure 7 and the inclined structure 8 is extended while the angle is also changing. The first connecting block 76 will drive the support plate 4 to move along the telescopic cavity 31 away from the lower structural plate 2 through the hinge 6. When the support plate 4 moves to the appropriate position and can provide support for the support frame 5, stop rotating the inclined tube 81 and the rotating tube 74, and pass the positioning rod 32 through the corresponding through-hole 41 to fix the support plate 4 to the cantilever 3.

[0046] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
