Detailed Description

The invention will be further described with reference to the following drawings and examples:

example 1:

referring to fig. 1-4, a non-welded flat panel fixture embedment includes a flat panel embedment body 1.

Specifically, equal-length reinforcing steel bars 2 are vertically arranged at four ends of the same side surface of the flat embedded part main body 1, and overlapped reinforcing sections 21 are arranged at the ends of the reinforcing steel bars 2.

The middle part of the flat embedded part main body 1 is also provided with a fixing through hole, and a fixing bolt 3 penetrates through the fixing through hole to be combined with a nut 4 to form a fixing structure for fixing with a template and fixing with a bracket.

Specifically, the nut sets up at dull and stereotyped built-in fitting main part medial surface, and fixing bolt sets up at the opposite side, and two combinations fix dull and stereotyped built-in fitting main part 1 at the template medial surface to, after fixed with the template, 3 outer silks of fixing bolt do not surpass two silks of nut 4 and half, under the circumstances of guaranteeing joint strength, can also make things convenient for the secondary connection of follow-up support.

In the specific use process, according to a construction design drawing, a hole is formed in a template at the position where an embedded part is arranged, and a non-welding flat plate fixing embedded part is fixed on the template at the hole punching position through a fixing bolt and a nut.

Before the embedded parts are installed, horizontal elevation control lines and vertical control lines are respectively marked on the completed concrete members to control the embedded positions of the embedded parts, the sizes of the embedded parts are distributed on the assembled templates according to drawing requirements, the embedded parts are fixed to corresponding positions, and the correct installation positions are ensured.

And binding main body steel bars, checking, closing the die, determining whether the position of the embedded part is accurate and the quality meets the requirements, and then pouring concrete.

The fixation of the non-welded flat plate fixed embedded part and the template is particularly important, and referring to fig. 3, the non-welded flat plate fixed embedded part and the template 100 need to be horizontally and vertically connected, the fixing bolt is screwed down, and the surface of the non-welded flat plate fixed embedded part is ensured to be in full contact with the template without loosening and rotating.

Then, after the concrete reaches the strength, removing the mold, and brushing anti-rust paint after the surface of the non-welded flat plate fixed embedded part is treated;

in the installation of the bracket, the bracket in the construction design can be installed by fixing the fixing through holes on the embedded parts and the nuts through the non-welding flat plate, referring to fig. 4, the fixing bolts 3 passing through the checking calculation pass through the fixing through holes and are combined with the nuts 4 to form a fixing structure, and the bracket 101 is fixed.

Due to the application of the non-welding flat plate fixed embedded part, the whole embedded part is not required to be welded, and is not required to be installed by special labor practitioners, so that the production cost is greatly reduced.

On the whole flow, the embedded installation process of the flat embedded part is simple and clear, the installation is convenient and flexible, professional electric welder construction operation is not needed, unified manufacturing and installation are realized, the process steps are relatively simple, one-time positioning and forming is carried out, the fixing part can be repeatedly used, the embedded part is fixed stably and reliably, the concrete vibration influence is avoided, and the embedded position is correct.

Meanwhile, the flat embedded part is fixed without being welded with the main body steel bar, and the steel bar stress of the main body is not influenced.

The building member has smooth surface and good appearance quality, and the embedded position of the embedded part is clear after the form removal without chiseling.
