technical field

The invention relates to a low-rise assembled steel frame composite light-weight wall house construction, and also relates to a method for building a low-rise assembled steel frame composite light-weight wall house.

Background technique

In the existing steel frame structure, the cross-section of steel beams and columns is relatively large, and the indoor beams and columns are prominent, which affects the layout of the house and the appearance of the interior. At the same time, other traditional filling materials such as clay bricks and aerated concrete blocks need to be built manually for the enclosure wall, and the floor slab needs to be poured with traditional craftwork, which leads to many wet operations on site, high labor costs, slow installation speed, and low installation and construction efficiency. Low cost and high cost. In order to assemble houses more quickly, innovations are needed.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a low-rise assembled steel frame composite light-weight wall building that is easy to install, high in efficiency, and low in cost. The present invention also provides a low-rise assembled steel frame The invention relates to a construction method of a composite lightweight wall building.

The present invention is realized through the following technical solutions:

A low-rise assembled steel frame composite light-weight wall building, characterized in that it includes a concrete foundation base (1), the upper end of the base and the bottom end of a box-shaped steel column (201) are provided with a connecting structure (501), and a box A connection structure (502) is provided at the connection between the shaped steel column (201) and the main steel beam (202), a connection structure (503) is provided at the connection between the main steel beam (202) and the secondary steel beam (203), and the floor is provided with a prefabricated Prestressed concrete ribbed floor (3), frame enclosure wall with composite lightweight wall (4)

The low-rise prefabricated steel frame composite light-weight wall building described above is characterized in that: the box-shaped steel column (201) needs to be poured with ordinary concrete to form a frame column with sufficient strength and a sufficiently small cross-section. And form the main frame structure of the house with the main steel beam (202) and the secondary steel beam (203).

The above-mentioned low-rise assembled steel frame composite light-weight wall building is characterized in that: the prefabricated prestressed concrete ribbed bottom plate (301). The base plate not only serves as a formwork, but also belongs to a part of the floor after the post-casting layer (302) is stacked, without the need for formwork, formwork support and formwork removal procedures.

The above-mentioned low-rise assembled steel frame composite light-weight wall house is characterized in that: the enclosure wall is a composite light-weight wall (4). The composite wall consists of an exterior finish (406), exterior heat preservation (405), filling lightweight concrete (404), and interior decoration panels (402). Each layer is connected with the tension joint (403) through the wall-through pipe (401) to enhance the integrity of the wall.

Compared with prior art, the present invention has following advantage:

1. Ordinary concrete is poured into the box-shaped steel column, which can effectively reduce the cross-section of the steel column and save steel. The beam and column are not highlighted indoors to enhance the indoor aesthetics.

2. Its maintenance system adopts the composite lightweight wall, which is a highly mechanized construction, green, environmentally friendly, high-efficiency and energy-saving material. It has high fire resistance limit, excellent shock resistance and good corrosion resistance. And it solves the defects of easy cracking and water seepage in the filling wall structure that usually exists in the steel structure.

3. Prefabricated prestressed concrete ribbed floor, thin thickness, high bearing capacity, convenient layout, no bottom form and support system, simplified process and reduced cost.

detailed description

A specific implementation of a low-rise fabricated steel frame composite light-weight wall building includes:

The first layer of box-shaped columns (201) is arranged on the concrete base (1), and a connection structure (501) is provided for connection and fixation.

The box-shaped steel column (201) on the first floor is fixed in place, the main steel beam (202) on the first floor is arranged, and a connecting structure (502) is provided for fixing.

The first floor main steel beam (202) is fixed in place, the first floor steel beam (203) is arranged, and a connecting structure (503) is provided to fix the main steel beam (202).
