Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

a high and large formwork support is shown in figure 1 and comprises upright rods 1 and connecting rods 2, and is shown in figure 2, wherein sleeve pipes 3 are sleeved at the end parts of the two ends of each connecting rod 2, connecting blocks 31 are hinged to the end parts of the sleeve pipes 3 along the radial direction of the sleeve pipes 3, and the connecting blocks 31 can rotate along the radial direction of the end parts of the sleeve pipes 3.

Meanwhile, one end of the connecting block 31, which is far away from the casing 3, is rotatably connected with a first joint 32, wherein the first joint 32 can rotate by taking the connecting block 31 as an axis.

Secondly, as shown in fig. 3, a plurality of first limit pins 11 are arranged on the circumferential surface of the vertical rod 1 along the axial direction of the vertical rod, and the number of the first limit pins 11 can be designed according to actual conditions. Meanwhile, the vertical rod 1 is sleeved with a lower bowl buckle 12 and an upper bowl buckle 13, and the edge of the lower bowl buckle 12 and the edge of the upper bowl buckle 13 form a support groove 121 with the vertical rod 1. And the first connector 32 may be partially inserted into the support groove 121. In addition, the inner side surfaces of the lower bowl buckle 12 and the upper bowl buckle 13 are provided with through holes 131. When the lower and upper bows 12 and 13 move on the vertical rod 1, the through hole 131 can be penetrated by the first limit pin 11. This facilitates the adjustment of the positions of the lower and upper clasps 12, 13 according to the specific requirements.

Here, as shown in fig. 4, when the end of the connecting rod 2 needs to be connected with the vertical rod 1, the lower bowl buckle 12 is moved to a designated position, then the lower bowl buckle 12 is rotated to make the outer surface of the lower bowl buckle 12 abut against the first limit pin 11, and then the first connector 32 is partially embedded into the supporting groove 121 of the lower bowl buckle 12 and abuts against the periphery of the vertical rod 1.

Then, the upper bowl buckle 13 is moved and covered on the first joint 32, so that the first joint 32 is also embedded into the support groove 121 of the upper bowl buckle 13, and then the upper bowl buckle 13 is rotated, so that the outer side wall of the upper bowl buckle 13 is abutted against the first limit pin 11. The first joint 32 can thus also be connected to the upright 1. And, a fixing pin is inserted into the through hole 131, so that the upper and lower bows 13 and 12 can be prevented from moving on the vertical rod 1 and affecting the stability.

Through above-mentioned connection structure, on the one hand connecting rod 2 can act as the horizontal pole that the level set up between two pole setting 1, and on the other hand, connecting rod 2 also can act as the diagonal brace between pole setting 1 and the ground.

Example two:

based on the first embodiment, as shown in fig. 5, the side surface of the connecting block 31 has a protrusion 311, the side surface of the connecting rod 2 is hinged with a limiting piece 33, and a notch 331 is formed in a side edge of the limiting piece 33, so that the notch 331 can be abutted to the protrusion 311. Therefore, when the connecting block 31 is adjusted to different positions, the corresponding notch 331 on the limiting sheet 33 can be butted with the bump 311, so that the connecting block 31 can be fixed, and the star effect can be kept after the position of the first connector 32 is adjusted.

Example three:

based on the second embodiment, as shown in fig. 6, in order to enable the connecting rod 2 to further function as a reinforcing structure for the tall and big formwork. The connecting rod 2 is further sleeved with a lantern ring 21, the lantern ring 21 is provided with a rotating shaft 211, the rotating shaft 211 is rotatably connected with a second connector 212, and the second connector 212 can be in butt joint with the upper bowl buckle 13 and the lower bowl buckle 12 on the vertical rod 1. Connecting rod 2 can be connected with many stands simultaneously under the state of slope like this to be favorable to improving the overall structure of high big formwork support.

Meanwhile, the surface of the connecting rod 2 is also provided with a plurality of second limit pins 22 along the axial direction, and the distance between two adjacent second limit pins 22 in the axial direction is equal to the axial length of the connecting lantern ring 21. In addition, the through hole 213 is also formed in the inner side wall of the lantern ring 21, so that on one hand, the lantern ring 21 can move to a specified position without being blocked by the second limit pins 22 according to needs, and on the other hand, after the lantern ring 21 reaches the specified position, the lantern ring 21 only needs to rotate to a certain degree to enable the two sides of the lantern ring 21 to be respectively abutted against the second limit pins 22 on the two sides, and therefore the possibility that the lantern ring 21 is separated from the space between the two second limit pins 22 can be reduced.

In addition, in order to further prevent the collar 21 from coming off the two stopper pins 22, the through hole 213 of the collar 21 may be blocked by a positioning pin.

Example four:

based on the third embodiment, as shown in fig. 7, since the first joint 32, the second joint 212 and the upright rod 1 are made of metal, and when they are connected, a certain gap is generated between the first joint 32 and the second joint 212 and the upright rod 1, so that after raining, rainwater is easily accumulated between the first joint 32 and the upright rod 1 or between the second joint 212 and the upright rod 1 for a long time, and thus electrochemical corrosion is easily generated between the first joint 32 and the upright rod 1 and between the second joint 212 and the upright rod 1, and the structural strength of a high-grade formwork is caused after a long time. Therefore, the buffer pads 321 are arranged on the sides of the first joint 32 and the second joint 212 facing the vertical rod 1, so that when the first joint 32 and the second joint 212 are installed on the vertical rod 1, the first joint 32 and the second joint 212 can be prevented from being damaged on the vertical rod 1, and accumulation of rainwater between the first joint 32 and the second joint 212 and the vertical rod 1 is reduced.
