Description
Technical Field
The invention relates to the field of construction of fabricated buildings, in particular to a hidden column template assembly of a fabricated building and a construction method thereof, wherein the hidden column template assembly can accelerate the template installation speed and effectively avoid the concrete mold expansion condition.
Background
Prefabricated buildings mainly comprise prefabricated concrete structures, steel structure buildings and the like, and are increasingly popular due to the adoption of a series of efficient construction processes such as standardized design, factory production, prefabricated construction and the like.
However, there are some problems with fabricated buildings in their particular construction. In particular, precast shear walls are typically formed at a construction plant and then shipped to a site for erection. In the process, all the prefabricated shear wall components are often connected through the hidden columns, and in the construction process of the hidden column formwork, split bolt holes are reserved on the prefabricated shear wall body, and the formwork is reinforced in a mode that split bolt rods are matched with steel pipes. In the construction method, the reinforcing speed of the template is slow, and if the reinforcing measures are unreliable, the concrete is also expanded. Therefore, the existing method has the problems of manpower and material resource consumption and unstable construction quality.
Disclosure of Invention
The invention aims to overcome the defects and provides a hidden column formwork assembly of an assembly type building and a construction method thereof, which aim to accelerate the installation speed of a formwork and effectively avoid concrete formwork expansion.
In order to achieve the above object, the present invention is realized by:
a built-in column template assembly of an assembly type building comprises a square steel fixing piece, a bolt and a filling piece; the square steel fixing piece is a square steel pipe with the length of 70mm x 50mm, the side edge of the square steel fixing piece is welded with angle steel with the length of 65mm x 30mm x 2mm, the filling piece is a steel pipe with the diameter of 28mm, a batten with the width of 28mm or square steel with the width of 28mm, and gaskets with different thicknesses of 28mm x 100mm, and the number of the used gaskets depends on the thickness of the formwork.
The construction method of the concealed column formwork assembly of the fabricated building comprises the following steps:
and 6, fixing the square steel installed on the filling piece on the angle steel.
The built-in column formwork assembly of the fabricated building and the construction method thereof change the traditional formwork reinforcing mode, the fabricated square steel fixing pieces are connected through bolts for reinforcement, the prefabricated shear wall and the square steel fixing pieces are connected in a prefabricated part factory and can also be transported to the site for connection before hoisting, the time of manual operation on an outer scaffold is effectively reduced, and the safety of workers is effectively ensured. And compared with the traditional formwork construction, the method of combining the square steel fixing piece and the filling piece reduces the reinforcement of various fasteners, reduces the phenomenon that the fasteners are not fastened by mistake in the manual construction process, ensures the construction quality, reduces the time required by formwork support and increases the working efficiency. Compare in traditional processing mode with great acceleration installation and demolition speed, reduction of erection time reduces the probability that mould rises takes place, and the component size error is little after pouring the shaping simultaneously, and the roughness obtains the guarantee.

and step 3: hoisting and installing the prefabricated shear wall;
and 4, step 4: transversely inserting the manufactured template into the square steel fixing piece;
and 5: mounting a square steel fixing piece on the other side of the hidden column;
step 6: the filling piece is arranged on the angle steel of the square steel fixing piece, wherein the small gasket can be made of on-site square wood instead of the square wood
Example 2
And 2, transporting to a site for hoisting, and installing the prefabricated shear wall.
And 3, vertically straightening the wood template.
And 4, mounting bolts to fix the square steel fixing parts on the two sides of the hidden column, wherein the bolts can be replaced by opposite-pulling screws.
And 5, mounting the filling piece on the angle steel of the square steel fixing piece, wherein the small gasket can be made of or replaced by square wood on site.
Example 3
Step 1: manufacturing a prefabricated shear wall in a prefabricated part factory according to a deepening drawing, and reserving bolt holes;
step 2: the square steel fixing pieces are fixed on the prefabricated shear walls on the two sides of the hidden columns through bolts (the square steel fixing pieces can be installed in prefabricated component factories or can be installed on components transported to the site);
