Description
Technical Field
The invention relates to the technical field of concrete construction of special-shaped buildings, in particular to a construction method of a special-shaped concrete column with a double-layer appearance.
Background
The existing template reinforcing construction method for common concrete columns is more complex, and the template reinforcing method for the fair-faced concrete blossoming column is more complex than the template processing method for the common concrete columns, and if the fair-faced concrete of the exterior finish needs to adopt a fair-faced template to meet the impression requirement, the details to be paid attention to are more. Aiming at a complex special-shaped concrete structure, a shaped steel template is generally adopted during construction, and the formwork construction of the special-shaped structure is completed through shaped design, processing and template installation, but the shaped steel template has the advantages of heavy weight, high installation difficulty, high requirement on the installation matching degree of the special-shaped structure, and high construction cost.
Disclosure of Invention
The invention aims to overcome the defects and provides a construction method for forming a double-layer appearance special-shaped concrete column by one-step pouring, which can enable the concrete column to meet the requirement of attractive, harmonious and uniform column body.
In order to achieve the above object, the present invention is realized by:
a construction method of a double-layer appearance special-shaped concrete column comprises the following steps
Step 1, pre-burying a counter-pulling screw rod for supporting an external special-shaped plate template during concrete pouring of an internal structural column, and ensuring the template forming effect;
step 2, adopting a digital processing technology to finish the deepening processing of the special-shaped board wooden template and the back edge, arranging serial numbers to facilitate the subsequent template installation operation,
step 3, after the binding of the profiled sheet fair-faced concrete steel bars is finished, paving a fair-faced formwork of the fair-faced concrete of the outer facing and erecting a back ridge, and after the installation of the outer side of the wood back ridge is finished, enabling the outer part of the whole modeling column to be supported in a square shape so as to facilitate the installation of a support frame and a reinforcing system;
step 4, filling an extruded sheet in a narrow space at the bottom of the cavity of the internal and external structures, wherein the position is narrow in size, the formwork supporting operation cannot be completed manually, the extruded sheet is used as an inner side template of the special-shaped plate, and the internal and external structures can be separated without stress connection;
step 5, building a support frame body at the back edge of the template according to stress calculation;
and 6, taking out the extruded sheet after the construction of the special-shaped sheet is finished, and cleaning the cavity.
To having bilayer structure and outward appearance dysmorphism concrete column, if adopt regularization steel form to consolidate the outer facing template of open flower column structure, need carry out the regularization processing preparation of steel form, and only once use, the construction input is huge to the unable installation of the inside steel form in narrow and small space is difficult to guarantee the construction quality of concrete. By adopting the special-shaped plate formwork supporting method, the formwork mounting quality of the special-shaped structure can be guaranteed, the single investment is lower than that of a steel formwork, the cost is saved, and the extrusion molding plate is adopted to replace part of the formwork in a narrow space, so that the problems that the structure interval is too small, the inner side formwork is not suitable for construction are solved, and the working efficiency is greatly improved.
Detailed Description
The invention is further illustrated by the following specific examples.
A construction method of a double-layer appearance special-shaped concrete column comprises the following steps
Step 1, pre-burying a counter-pulling screw rod for supporting an external special-shaped plate template during concrete pouring of an internal structural column, and ensuring the template forming effect;
step 2, adopting a digital processing technology to complete the deepening processing of the special-shaped board wooden template and the back edge, arranging serial numbers so as to facilitate the subsequent template installation operation,
step 3, after the binding of the profiled sheet fair-faced concrete steel bars is finished, paving a fair-faced formwork of the fair-faced concrete of the outer facing and erecting a back ridge, and after the installation of the outer side of the wood back ridge is finished, enabling the outer part of the whole modeling column to be supported in a square shape so as to facilitate the installation of a support frame and a reinforcing system;
step 4, filling an extruded sheet in a narrow space at the bottom of the cavity of the internal and external structures, wherein the position is narrow in size, the formwork supporting operation cannot be completed manually, the extruded sheet is used as an inner side template of the special-shaped plate, and the internal and external structures can be separated without stress connection;
step 5, building a support frame body at the back edge of the template according to stress calculation;
and 6, taking out the extruded sheet after the construction of the special-shaped sheet is finished, and cleaning the cavity.
The construction method of the invention is further illustrated by a construction step of a concrete column with a flower-shaped scattering appearance:
the style of flowering post is double-deck concrete structure, and inside is the rectangle post, and the form structural slab is dispersed to the outsourcing dysmorphism, and interior outer structure is thrown off, and the rectangle post construction is under construction the back in advance, is carrying out outside special-shaped structural slab construction operation, can guarantee the atress and the impression requirement of inside and outside two part structure like this greatly, and outside special-shaped board construction steps are as follows:
step 1, after binding of external clear water concrete steel bars is completed, laying a clear water template of the outer facing clear water concrete and building back ridges.
And 2, pre-burying the screw for reinforcing the post-stage pattern column.
And 3, pre-burying a screw rod in the main body column, and wrapping an extruded plate around the main body column to ensure that the concrete of the patterned column cannot be bonded, so that the patterned column is not in stressed connection with the main body column.
And 4, building a support frame body.
And 5, constructing the inner column, and then pouring the outer facing.
And 6, taking out the extruded sheet.
To having bilayer structure and outward appearance dysmorphism's concrete column, if adopt regularization steel form to consolidate the exterior facing template of open column structure, need carry out the regularization processing preparation of steel form, and only once use, the construction input is huge to the unable installation of the inside steel form in narrow and small space is difficult to guarantee the construction quality of concrete. By adopting the special-shaped plate formwork supporting method, the formwork mounting quality of the special-shaped structure can be guaranteed, the single investment is lower than that of a steel formwork, the cost is saved, and in a narrow space, the extruded sheet is adopted to replace part of the formwork, so that the problems that the structure interval is too small, the inner side formwork is not suitable for construction are solved, and the working efficiency is greatly improved.
