[0043] A top support 1, a horizontal rod 2 and a vertical rod 3 arranged at the top of a high-formwork system;

[0044] The top support 1 is provided with a clamping assembly, which comprises an adjusting piece 4 and a sliding sleeve 5 mounted on the top support 1. The adjusting piece 4 is adapted to adjust the position of the sliding sleeve 5 in the height direction of the top support 1. The outer side of the sliding sleeve 5 is provided with a clamping piece 6, which is adapted to clamp the vertical rod 3 from left to right along the side of the horizontal rod 2. The adjusting piece 4 is in a sleeve structure and is internally provided with internal threads. The outer side of the vertical rod of the top support 1 is provided with external threads. The height of the adjusting piece 4 is adjusted by the internal and external threads.

[0045] The clamping piece 6 is provided with four corner points arranged in a rectangular structure. The clamping piece 6 comprises a main rod 61, a secondary rod 62 and an auxiliary rod 63. One end of the main rod 61 is rotatably mounted on the side of the sliding sleeve 5. One end of the secondary rod 62 is rotatably mounted on the top support 1. One end of the auxiliary rod 63 is rotatably mounted with a clamping body 7. The free ends of the main rod 61, the secondary rod 62 and the auxiliary rod 63 are rotatably mounted by a rotating shaft. The clamping body 7 is adapted to be slidably mounted on the top support 1 along the length direction of the horizontal rod 2 and is adapted to clamp the vertical rod 3 from left to right.

[0046] The height of the sliding sleeve 5 is adjusted by rotating the adjusting piece 4. The multi-link structure composed of the main rod 61, the secondary rod 62 and the auxiliary rod 63 is relatively rotated, thereby enabling the clamping body 7 to clamp or release the vertical rod 3 from left to right. During the clamping or releasing process of the vertical rod 3, the clamping body 7 always moves along the length direction of the projection of the horizontal rod 2 on the horizontal plane.

[0047] In the embodiment 2, the following improvements are made on the basis of the above-mentioned embodiments, as shown in the figure. Figure 3 The clamping body 7 comprises a pressure receiving plate 71, two ends of which are respectively connected with a guide plate 72 and a clamping plate 73. The pressure receiving plate 71 is adapted to be arranged at an angle of 45° with the projection of the horizontal rod 2 and the vertical rod 3 on the horizontal plane. The guide plate 72 is adapted to move along the length direction of the side of the horizontal rod 2. The clamping plate 73 is adapted to clamp the vertical rod 3 from left to right. The pressure receiving plate 71 is adapted to be arranged at an angle of 90° with the projection of the horizontal rod 2 and the vertical rod 1 on the horizontal plane. The guide plate 72 moves along the length direction of the projection of the horizontal rod 2 on the horizontal plane. The projection of the clamping body 73 on the horizontal plane is adapted to clamp the vertical rod from left to right.

[0048] The guide plate 72 comprises a connecting plate one 721 and a connecting plate two 722 integrally connected with the pressure receiving plate 71. The connecting plate two 722 comprises a connecting part one 7221 coplanar with the connecting plate one 721 and a folding part one 7222 perpendicularly arranged with the pressure receiving plate 71. The connecting plate one 721 and the connecting part one 7221 are used to fit the side of the horizontal rod 1 to limit the forward and backward movement of the horizontal rod 1, i.e. the freedom degree along the length direction of the vertical rod 2. The folding part one 7222 improves the structural stability of the connecting part one 7221 and the connecting plate one 721.

[0049] The clamping plate 73 includes a connecting plate 3 731 and a connecting plate 4 732 integrally connected to the pressure plate 71. The connecting plate 4 732 includes a connecting portion 2 733 coplanar with the connecting plate 3 731 and a folding portion 2 734 perpendicularly disposed to the pressure plate 71. The connecting plate 2 731 and the connecting portion 2 733 clamp the side of the longitudinal rod 2, restricting the left and right movement of the longitudinal rod 1, i.e., the degree of freedom along the length direction of the horizontal rod 1. The folding portion 2 734 improves the structural stability of the connecting portion 2 733 and the connecting plate 1 731.

[0050] Example 3, based on the above examples, makes the following improvements: Figures 1 to 3 As shown, each of the pressure plates 71 is vertically provided with a set of corresponding through holes, that is, the two sets of pressure plates 71 distributed diagonally are provided with corresponding through holes. Each set of through holes is equipped with tie bolts 8. Each set of tie bolts 8 includes at least two tie bolts 8, which are staggered. The tie bolts 8 located on the two diagonals are staggered vertically. This structural arrangement can avoid the obstacle area when they overlap. The tie bolts 8 can be used to tie the two sets of clamping bodies 6 distributed diagonally to ensure the stability and reliability of the structure.

[0051] like Figure 5 and Figure 6 As shown, a pressure plate 9 is arranged between the end of the tie bolt 8 and the clamping body 7. The pressure plate 9 includes a bearing part 91 and pressure parts 92 located at both ends of the bearing part 91. The bearing part 91 is provided with a through hole corresponding to the position of the through hole. The pressure part 92 is provided with a pressure body 93 arranged parallel to the tie bolt 8 on the corresponding pressure plate 71. The connecting part 1 7221 and the connecting part 2 733 are provided with horizontally inclined holes suitable for the passage of the pressure body 93. By connecting the tie bolt 8, the pressure plate 9 and the bearing plate 71 are pressed and fixed, and the pressure body 93 can also press and fix the corresponding rod along the horizontally inclined holes to ensure structural stability and structural strength. After pressing, the pressure body 93 has a two-way figure-eight structure along the length direction of the corresponding rod, ensuring the anti-slip effect between the rod and the corresponding connecting part and the connecting plate, and improving the structural stability and anti-slip effect of the high formwork support structure.

[0052] Example 4, based on the above examples, makes the following improvements, such as... Figure 1 and Figure 4 , Figure 8As shown, a support body 10 is provided in the overlapping area of ​​the vertical bar 3 and the horizontal bar 2 in the horizontal plane projection. The support body 10 includes top support plates 101 located at the top and bottom, and a support plate 102 located between the two top support plates 101. The support plate 102 is vertically arranged and has a cross-shaped structure. The diagonal of the support plate 102 coincides with the diagonal of the projection structure of the two top support plates 101 in the horizontal plane. The support plate 102 on the support body 10 is pressed and fixed by tie bolts 8, which fixes the position of the support body 10 between the horizontal bar 1 and the vertical bar 2, prevents vertical movement between the two bars, and improves the support strength.

[0053] The support plate 102 is provided with a connecting hole for the tie bolt 8 to pass through.

[0054] Example 5, based on the above examples, makes the following improvements, such as... Figure 10 and Figure 11 As shown, the auxiliary rod 63 is a telescopic rod suitable for clamping and fixing longitudinal rods 3 of different sizes and specifications.

[0055] Example 6, based on the above examples, makes the following improvements, such as... Figure 9 As shown, the top of the top support 1 is provided with a sliding groove 11 for the clamping body 7 to clamp the vertical rod 3 on the left and right. The sliding groove 11 has a sliding block 12 inside it, and the sliding block 12 is welded and fixed to the bottom of the clamping body 7. The cross section of the sliding groove 11 is a T-shaped structure.

[0056] A construction method for a safety clamping mechanism for the top longitudinal and transverse bars of a high formwork support includes the following steps:

[0057] Step 1: Make the top support 1

[0058] A groove 11 is made on the top support plate at the top of the top support 1 along the length of the crossbar 2. A clamping body 7 is installed in the groove 11.

An adjusting part 4 is connected through the external thread. The upward height of the sliding sleeve 5 is adjusted by the threaded connection between the adjusting part 4 and the upright.

[0059] Step 2: Assemble clamping component 6

[0060] Four sets of main rods 61 are connected to the outside of the sliding sleeve 5 via connecting shafts. The tops of the four sets of main rods 61 are connected to secondary rods 62 and auxiliary rods 63 via connecting shafts. The tops of secondary rods 62 are connected to the top support plate of the top support 1 via connecting shafts. The secondary rods 62 enhance the structural stability. The tops of auxiliary rods 63 are connected to the side of the clamping body 7 via connecting shafts.

[0061] Step 3: Assemble the high formwork system

[0062] Install the bottom support on the floor or ground at the predetermined mark on the design drawing, install the vertical rods, horizontal rods 2 and scissors braces of the main body structure layer by layer, install the top support 1 at the top, adjust the top support 1 to the design elevation, install the horizontal rods 2 on the top support 1 top support horizontal plate, install the support body 10 and vertical rods 3 at the predetermined mark of the horizontal rods 2;

[0063] Step four: assemble the horizontal rods 2 and vertical rods 3

[0064] By rotating the adjusting part 4, the sliding sleeve 5 is driven to move upward along the outer thread, and then the clamping part 6 is driven to clamp the vertical rod 3 along the length direction of the horizontal projection of the horizontal rod 2;

[0065] Step five: install the tensioning bolt 8
