Cantilever frame beam side all-embedded mounting and erecting device

Abstract

The invention discloses a cantilever frame beam side all-embedded mounting and erecting device. The cantilever frame beam side all-embedded mounting and erecting device comprises an I-beam and embedding devices; the I-beam is provided with a steel plate base, and is fixedly connected with an embedding device I arranged in a concrete wall through a bolt; a supporting point fixing device I of which the angle can be adjusted freely is arranged on the lower portion, which is far away from the concrete wall, of the I-beam; the supporting point fixing device I is connected with a supporting point fixing device II arranged on the concrete wall through a supporting steel tube; the supporting point fixing device II is connected with an embedding device II arranged in the concrete wall through a bolt; trapezoidal screw threads are arranged in two ends of the supporting steel tube; a positive and negative trapezoidal thread adjusting screw is arranged on the middle upper portion of the supporting steel tube; each of the supporting point fixing device I and the supporting point fixing device II is provided with a trapezoidal screw of which the angle can be adjusted freely; and the trapezoidal screws are respectively connected with the screw threads in the two ends of the supporting steel tube. The cantilever frame beam side all-embedded mounting and erecting device is quite simple in structure and quite convenient to assemble and disassemble; materials are saved greatly; and the schedule is increased.

Description

technical field [0001] The invention mainly relates to the field of building construction auxiliary equipment, and specifically discloses a fully pre-embedded installation and erection device on the side of a cantilevered girder. Background technique [0002] When traditional cantilevered I-beams are installed, such as figure 1 As shown, the I-beam b is laid on the floor a through the shear wall, and then fixed to the floor with the steel bar c. Because it is too heavy, the installation is extremely tiring, cumbersome and time-consuming. When it passes through the shear wall, it will be damaged. The cross-section of the wall leads to a discount in the design strength and increases the difficulty of carpentry molding. It is even more difficult to dismantle it. Sometimes it takes two people half a day to remove an I-beam that runs through the shear wall. If it cannot be hoisted, it will be a big hidden danger to safety. After the demolition, the wall will be riddled with hol...

Problems solved by technology

[0002] When traditional cantilevered I-beams are installed, such as figure 1 As shown, the I-beam b is laid on the floor a through the shear wall, and then fixed to the floor with the steel bar c. Because it is too heavy, the installation is extremely tiring, cumbersome and time-consuming. When it passes through the shear wall, it will be damaged. The cross-section of the wall leads to a discount in the design strength and increases the difficulty of carpentry molding

It is even more difficult to dismantle it. Sometimes it takes two people half a day to remove an I-shaped beam that runs through the shear wall. If it cannot be hoisted to a position that cannot be hoisted, safety is a big hidden danger

After the demolition, the wall will be riddled with holes everywhere, which is shocking and greatly reduces the construction quality (not to mention that the strength of the hole added later will be discounted, but it is undoubtedly the biggest source of leakage. I-beams are indoors. After the fixed position is removed, it will also cause leakage in the later stage), and it also greatly delays the construction progress
