The installer does not need to control the balance of the beam and column in the air by his own strength, which saves effort and improves efficiency. The installation is also easy to carry.

The outer wall of the positioning block 23 is slidably mounted on the inner wall of the fixed block 2. The mounting assembly also includes a sliding rod 24, a sliding rope 25, a positioning rod 26, a spring 27, and a support plate 28. The outer wall of the sliding rod 24 is fixedly connected to one end of the sliding rope 25. The other end of the sliding rope 25 is mounted on the outer wall of the sliding rod 24 on the other side. One end of the sliding rod 24 is fixedly mounted on one side of the outer wall of the positioning block 23. The outer wall of the sliding rod 24 is slidably mounted on the inner wall of the fixed block 2. One end of the sliding rod 24 penetrates the inner wall of the fixed block 2 and extends to the fixed The outer wall of the block 2 is fixedly connected to one end of the positioning rod 26 and one end of the spring 27, and the other end of the spring 27 is fixedly installed on the inner wall of the fixed block 2. The outer wall of the positioning rod 26 is slidably connected to the inner wall of the fixed block 23. The outer wall of one side of the positioning rod 26 is fixedly connected to one end of the support plate 28. The outer wall of the support plate 28 is slidably installed on the inner wall of the fixed block 2. One end of the support plate 28 penetrates the outer wall of the fixed block 2 and extends to the inside of the fixed block 2. The installation assembly also includes a pull ring 3, a positioning rod Two 31, spring three 32, one side outer wall of the pull ring 3 is fixedly installed on the bottom of the support plate 28, one side outer wall of the positioning rod two 31 is fixedly connected with one end of the spring three 32, the other end of the spring three 32 is fixedly installed on the inner wall of the fixed block two 21, the outer wall of the positioning rod two 31 is slidably installed on the inner wall of the fixed block two 21, one end of the positioning rod two 31 penetrates the outer wall of the fixed block two 21 and extends to the inside of the fixed block two 21, the other end of the positioning rod two 31 penetrates the outer wall of the support plate 28 and extends to the inside of the support plate 28, and the outer wall of the positioning rod two 31 is slidably connected with the inner wall of the support plate 28.

[0037] When in use, by welding the mounting block 12 on the side wall of the beam column 11, welding the fixing block 1 2 and the fixing block 21 on the side wall of the steel column 1, and after the welded steel column 1 is erected and fixed by a crane, the beam column 11 is hoisted to the steel column 1, and the installer takes the elevator to the node, and the two ends of the auxiliary beam column 11 are aligned to the corresponding fixing block 1 2 and the fixing block 21, and then the crane operator is cooperated to lower the beam column 11 downward, and the beam column 11 will squeeze the support plate 28 to move downward, so that the support plate 28 drives the positioning rod 1 26 to move, and the positioning rod 1 26 moves out of the positioning block 23. When the mounting block 12 slides to a horizontal position with the positioning block 23, the positioning block 23 pops out from the inside of the fixing block 2 under the action of the spring 1 22, and is inserted into the mounting block 12 to complete the installation. After the steel column 1 and the beam column 1 are completed, After the installation between 1, the spring three 32 provides elastic force to the positioning rod two 31, so that the positioning rod two 31 can be stuck in the interior of the support plate 28, thereby fixing the position of the support plate 28. When the beam column 11 needs to be disassembled, the sliding rod one 24 is pushed to the side away from the spring two 27, so that the sliding rod one 24 drives the positioning block 23 to move, and the sliding rod one 24 drives the sliding rope 25 to move, and the sliding rope 25 drives the positioning block 23 on the other side of the beam column 11 to move synchronously, so that the two positioning blocks 23 are moved out of the installation block 12 at the same time, and the beam column 11 can be unlocked. At this time, the support plate 28 provides supporting force for the beam column 11, so that even if the beam column 11 is unlocked, the probability of falling directly from a high altitude is greatly reduced because both ends of the beam column 11 are supported by the support plate 28.
