Problems solved by technology
The disadvantage of these two technologies is that the embedded iron parts are fixed by the steel bars or templates in the concrete components. When pouring concrete, the vibration will cause the steel bars or templates to shift and deform, causing the embedded iron parts to move with them. Affected the precise positioning of iron parts
These two pre-embedded iron parts fixing technologies are no longer suitable for industrial buildings with large tonnage and high precision requirements in the transportation industry, energy industry, aviation industry, etc.

Embodiment Construction
[0011] The present invention will be further described in conjunction with the accompanying drawings.
[0012] The present invention carries out according to the following steps: (1), weld steel pipe or reinforcing bar as connecting rod 2 at the front face of embedded iron part 1, as figure 1 As shown, the embedded iron part 1 is fixed by connecting the connecting rod 2 with the external stable body 3, as shown in figure 2 As shown; (2), according to the conventional method, tie the reinforcement and seal the mold around the embedded iron part 1, such as image 3 As shown, concrete is poured, and after the concrete reaches strength, the formwork is removed and the connecting rod 2 is cut off, such as Figure 4 shown.

The invention relates to a fixation and installation method of embedded iron parts. The method comprises the following steps: (1) welding a steel tube or a reinforced bar on a front surface of the embedded iron parts as a connecting rod, and fixing the embedded iron parts by connecting the connecting rod and an external firmware; and (2) tying the reinforced bars, molding or pouring concrete by taking the embedded iron parts as a formwork around the embedded iron parts, demolding and cutting off the connecting rod after the concrete reaches the strength. Compared with the existing installation method of the embedded iron parts, the method is not affected by concrete vibrating function and can help accurately position and install the embedded iron parts without deviation and displacement, and especially for large-tonnage embedded iron parts, the method does need a steel frame for fixing the iron parts to be installed in a member, thus saving cost. The method is characterized by rational design, convenient use and cost saving and especially suitable for high-precision installation of large-tonnage embedded iron parts.
Description
technical field [0001] The invention belongs to the field of construction engineering, in particular to a method for fixing and installing pre-embedded iron parts in concrete components. Background technique [0002] The existing pre-embedded iron parts fixed installation technology is: 1. bolt fixing method: that is, the iron parts are fixedly installed by connecting the iron parts with the formwork through bolts. This technology is suitable for concrete members with less reinforcement and less embedded iron anchor reinforcement. 2. Welding method: that is, iron parts are connected and installed with steel bars or fixed steel frames in components by welding. This technology is suitable for concrete components with tight reinforcement, heavy embedded iron parts, and many anchor bars. The disadvantage of these two technologies is that the embedded iron parts are fixed by the steel bars or templates in the concrete components. When pouring concrete, the vibration will cause ...
