Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated buildings, and particularly relates to a prefabricated fin-shaped pre-welded structure for wrapping a square column with a circular column and an installation method thereof. Background Art

[0002] With the continuous transformation of the construction industry, prefabricated building structures have developed rapidly. Many prefabricated products have entered the market, setting off a huge wave in the construction industry. Compared with traditional buildings, prefabricated steel structure buildings have many advantages and develop rapidly. Their installation speed is faster, the construction quality is easy to guarantee, the steel structure also has stronger seismic resistance, the foundation cost is low, and steel is a recyclable material. Compared with on-site construction methods, the steel structure is more environmentally friendly, reducing the negative impact on the environment and following the principle of sustainable development.

[0003] As is well known, in most public places, the column shape is usually cylindrical. The prefabricated column wrapping structure is a column structure used in prefabricated buildings, which mainly plays a decorative role and does not need to play a supporting role, and is widely used in the construction field.

[0004] At present, the prefabricated circular column wrapping structure is a blank area in prefabricated buildings. At present, most traditional column wrapping structures are traditional decoration processes, and reinforced concrete columns are used. The construction process for wrapping steel columns in steel structure buildings is extremely rare. The existing prefabricated circular column process generally adopts fully prefabricated circular columns. The vertical connection of fully prefabricated columns generally adopts grouting sleeves for connecting one by one. Due to the high density of node steel bars, high processing precision is required, the operation difficulty is relatively large, and the fully prefabricated columns are relatively heavy. Moreover, most of them do not wrap columns, there are few clear column wrapping decoration processes, and there is a lack of corresponding auxiliary conversion components for changing circular columns into square columns. It relies on the technical experience of construction workers for construction, and the installation accuracy cannot be guaranteed. The present application aims to provide a construction structure and plan that can be adopted when a circular column needs to be wrapped into a square column during the decoration process, and it is necessary to meet the characteristics of fast installation and disassembly of prefabricated assemblies.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Such as Figures 1 - 5As shown in the figure, an assembled fin-shaped pre-welded structure for a cylindrical column wrapped around a square column includes a round steel column 1, a fin-shaped pre-welded component, and a base plate 3. The outer side of the round steel column 1 is sprayed with fireproof coating. The number of fin-shaped pre-welded components is multiple and they are arranged on the outer side of the round steel column 1. The base plate 3 is arranged on the outer side of the fin-shaped pre-welded component, and the base plate 3 is installed on the fin-shaped pre-welded component by self-tapping screws. The several fin-shaped pre-welded components are arranged at equal intervals on the outer side of the round steel column 1. The fin-shaped pre-welded component includes eight fin-shaped pre-welded parts 2 arranged in sequence on the outer side of the round steel column 1. The outer side of the fin-shaped pre-welded component encloses a square structure for installing the outer base plate 3. Eight fin-shaped pre-welded parts 2 form a circle in a group, and then another circle is installed at a certain distance. The periphery of the fin-shaped pre-welded component forms a square contour, so that after the base plate 3 is installed, the base plate 3 just encloses a square structure, realizing the assembled transformation from a cylinder to a square column.

[0035] The fin-shaped pre-welded part 2 of the present invention is the main conversion component for changing a cylinder into a square column. The fin-shaped pre-welded part 2 is a hollow cavity structure formed by sequentially connecting an outer support plate 21, a first connecting plate 22, an arc-shaped plate 23, and a second connecting plate 24. The material of the fin-shaped pre-welded part 2 is stainless steel.

[0036] Among them, the arc-shaped plate 23 matches the radian of the round steel column 1 and is welded on the outer side of the round steel column 1; the outer support plate 21 and the first connecting plate 22 are vertically arranged, and the outer support plate 21 and the second connecting plate 24 are arranged at an angle of 45°.

The connections between the outer support plate 21 and the first connecting plate 22, between the first connecting plate 22 and the arc-shaped plate 23, and between the arc-shaped plate 23 and the second connecting plate 24 are all provided with rounded corners. Designed into a circular arc and chamfer, this design reduces stress concentration, protects the operators, and increases the aesthetics;

The first connecting plates 22 or the second connecting plates 24 of adjacent fin-shaped pre-welded parts 2 are arranged corresponding to each other. A gap is left between adjacent first connecting plates 22 and between adjacent second connecting plates 24.

[0039] Preferably, the outer support plates 21 at the corresponding positions of different fin-shaped pre-welded components are on the same plane, meeting the installation requirements of the base plate 3. The outer support plate 21 is wide in height and has a large contact surface with the base plate 3 after connection, reducing the difficulty of nail fixing and enhancing the stability of the base plate 3 after installation;

[0040] The fitting materials required for the present invention are made of stainless steel. All fittings are prefabricated in the factory, reducing construction time and processes and achieving fast assembly and disassembly.

[0041] The installation method of the above-mentioned assembled fin-shaped pre-welded structure for cylindrical wrapping of square columns includes the following steps:

[0042] S1: Prepare the round steel column 1 and spray fireproof coating on the outer side of the round steel column 1;

[0043] S2: Pre-weld fin-shaped pre-welded components on the outer side of the round steel column 1. Eight fin-shaped pre-welded parts 2 are in a group and pre-welded in a circle;

[0044] S3: At a predetermined interval, weld another group of fin-shaped pre-welded components on the outer side of the round steel column 1 using the same process;

[0045] S4: Install the base plate 3 on the adjacent outer support plates 21 by screws. Four base plates 3 enclose a square column structure to complete the installation.

[0046] The technical solution of the present invention realizes the transformation from a cylindrical column to a square column through the assembled fin-shaped pre-welded structure for cylindrical wrapping of square columns, providing a feasible reference process for the transformation from a cylindrical column to a square column in actual construction. It mainly uses assembled steel structures to solve the problem of wrapping a cylindrical column into a square column in building construction. Through combined construction and dry construction, the assembled fin-shaped pre-welded structure for cylindrical wrapping of square columns is completed; realizing the cylindrical wrapping of square columns in steel structure buildings, different from traditional construction processes, with a simple overall structure, convenient installation, and meeting the characteristics of fast assembly and disassembly.
