Abstract

The present invention is specifically a kind of construction method for improving the medium-and-large-sized installation of embedded parts precision of Equipment Foundations；It is characterized in that：The back i.e. outside for being included in embedded iron parts sets Screw arbor with nut at both-ends；Embedded iron parts and the tie with reinforcing bar on basis are fixed；Position adjustment is carried out to embedded iron parts；Set up formwork for placing and Screw arbor with nut at both-ends component is set, formwork for placing corresponds to the position of standing screw on embedded iron parts and is provided with through hole, and when formwork for placing is installed, the fixing bolt of embedded iron parts passes from the through hole on formwork for placing, and drawing is tightened；Into formwork for placing during casting concrete, avoid concrete from directly impacting built-in fitting, during concrete vibrating, avoid vibrating head from directly being contacted with embedded iron parts.This construction method solve thes problems, such as large-scale embedded iron parts off normal, hollowing, unmanageable alignment error, and installs condition of providing convenience for later process.

Description

Improve the construction method of the medium-and-large-sized installation of embedded parts precision of Equipment Foundations

Technical field

The present invention relates to the installing area of Equipment Foundations, is specifically a kind of medium-and-large-sized installation of embedded parts essence of raising Equipment Foundations The construction method of degree.

Background technology

Typically pass through reinforcing bar（Directly welding or iron wire colligation are on main reinforcement skeleton and template）To position embedded iron parts, but It is for the bigger embedded iron parts of appearance and size（As length or width are more than 500mm）, due to the fixation side of colligation or welding Formula is not firm and impact during casting concrete, finds that the positioning precision of embedded iron parts is overproof tight after frequently can lead to form removal Weight, shadow is so as to sound concrete structure presentation quality and later process（Such as support of pipelines, cable testing bridge）Installation quality.

The content of the invention

It is an object of the present invention to provide a kind of high-precision installation of embedded parts method, such a installation method are especially suitable In the installation of large-scale built-in fitting.

In order to achieve the above object, the present invention is realized in：

A kind of construction method for improving the medium-and-large-sized installation of embedded parts precision of Equipment Foundations, including

Step 1, by drawing making embedded iron parts, be that outside sets standing screw at the back of embedded iron parts；

Step 2, according to the status requirement of embedded iron parts in drawing by step 1 embedded iron parts temporarily with basis framework of steel reinforcement Banding fixed；

Step 3, as the status requirement in chromosome paper to described in step 2 embedded iron parts carry out position adjustment；

Step 4, set up formwork for placing on the outside of the framework of steel reinforcement of Equipment Foundations and Screw arbor with nut at both-ends component is set, formwork for placing corresponds to The position of standing screw is provided with through hole on embedded iron parts；

Step 5, the standing screw on embedded iron parts passed from the through hole on formwork for placing；

Step 6, to the standing screw end set fixing nut through formwork for placing；

Step 7, the casting concrete into formwork for placing, during casting concrete, concrete slurry is avoided directly to impact built-in fitting, together When vibrating, avoid vibrating head from directly being contacted with embedded iron parts.

This construction method fixes large-scale embedded iron parts, rubber tradition embedded iron parts and basis with stable template system For the mode that tie with reinforcing bar is fixed, the fixed effect of embedded iron parts is more preferably and efficiency of construction is higher；And this construction party Method solve thes problems, such as large-scale embedded iron parts off normal, hollowing, unmanageable alignment error, at the same reduce the later stage repair into This, improves concrete structure presentation quality, and install condition of providing convenience for later process.

Brief description of the drawings

Fig. 1 is the step schematic diagram of this construction method.

Fig. 2 is using the embedded part structure schematic diagram after this construction method.

Embodiment

The present invention is further illustrated below by way of specific embodiment.

As shown in Figure 1 and Figure 2, a kind of construction method for improving the medium-and-large-sized installation of embedded parts precision of Equipment Foundations, including

Step 1, by drawing making embedded iron parts 1, be that outside sets standing screw 2 at the back of embedded iron parts 1；

Step 2, according to the status requirement of embedded iron parts in drawing 1 by step 1 embedded iron parts 1 temporarily with basis reinforcing bar The banding fixed of frame 3；

Step 3, as the status requirement in chromosome paper to embedded iron parts described in step 21 carry out position adjustment；

Step 4, set up formwork for placing 4 in the outside of framework of steel reinforcement 3 of Equipment Foundations and Screw arbor with nut at both-ends component 5 is set, formwork for placing 4 The position of standing screw 2 is provided with through hole on corresponding embedded iron parts 1；

Step 5, on embedded iron parts 1 standing screw 2 passed from the through hole on formwork for placing 4；

Step 6, to the end set fixing nut of standing screw 2 through formwork for placing 4；

Step 7, the casting concrete into formwork for placing, during casting concrete, concrete slurry is avoided directly to impact built-in fitting, together When vibrating, avoid vibrating head from directly being contacted with embedded iron parts.

This construction method fixes large-scale embedded iron parts, cast-in-place traditional embedded iron parts and basis with stable template system For the mode that tie with reinforcing bar is fixed, the fixed effect of embedded iron parts is more preferably and efficiency of construction is higher；And this construction party Method solve thes problems, such as large-scale embedded iron parts off normal, hollowing, unmanageable alignment error, at the same reduce the later stage repair into This, improves concrete structure presentation quality, and install condition of providing convenience for later process.
