detailed description

A high-strength concave-convex steel connecting house, see Fig. 1, comprising a skeleton, a wall and a roof, and a door and a window, the skeleton including a column, a beam, a bottom joint, a corner joint, a shear joint, and a staircase And so on.

High-strength concave-convex square rectangular tube: Refer to Figures 2 to 4, including four (or six) square-shaped tubes 1a on the side of each of the square-shaped rectangular tubes 1a, which are bent and bent on the side of each rectangular tube 1a. A recessed notch is formed, and inside each notch is provided with a bent inner sliding channel which is the same direction as the notch and wider than the notch.

The notch includes two sides connected to the side of the rectangular tube 1a, and the inner slide comprises two sides connected together, a bottom surface, and two upper surfaces respectively connected to the two sides of the notch.

The two sides of the notch are perpendicularly connected to the side of the rectangular tube 1a, and the two upper sides of the inner slide are respectively perpendicularly connected to the two sides of the notch, and the inner slide is square.

The four sides of the square tube are at least two of the adjacent sides, and the transition joint is a joint weld.

In order to verify the substantial increase in the moment of inertia of the rectangular tube 1a of the present invention, the inventors performed the following calculation and analysis on the rectangular tube 1a of the present invention: a plurality of rectangular tubes of the same table as the following dimensions are taken.

Calculating the moment of inertia of the square tube according to the dimensional relationship in Fig. 5,

According to the comparison of the data in the above table, the moment of inertia of the square tube is increased by 50%-100% compared with the moment of inertia of the square tube of the same size. Among all the parameters of the square tube, H2 has a great influence on the variation of the moment of inertia. The larger the H2, the larger the moment of inertia; the larger the B2, the smaller the overall moment of inertia, and the B2 value should be reduced as much as possible in the overall design.

In addition, the inventor conducted a finite element analysis by software, and found that the square tube has a significantly higher yield resistance than the C-shaped steel of the same size, and the yield resistance is related to the wall thickness D. When the wall thickness is 1 mm, the yield resistance is increased by 1.5 times. When the thickness of 2mm is increased by 11 times, when it is 3mm, it is increased by 26 times. Therefore, it can be estimated that if the steel structure is built with 3mm, the rectangular tube is built to at least 7 floors, so it is suitable for high-rise residential use.

High-intensity concave-convex grooved rectangular tube: Referring to Fig. 5 - Fig. 8, the whole steel plate is bent and enclosed into a circular moment tube 1b, which is composed of four circular arc sides. Moreover, a notched notch 2 is formed between each two adjacent arcuate sides, and a total of four (or six) recessed notches 2 are provided.

b. repeating step a four times to form four vertical protrusions; or step a simultaneously forming four vertical protrusions;

c. bending the inwardly recessed groove at the bottom of the two sides of the square protrusion in step a, the height of the groove and the circular tube The notches of 1b have the same height, and lateral projections are formed on both sides of the groove, and the depth between the lateral protrusions and the groove is the same as the upper surface of the inner slide of the circular tube 1b; after the step c is completed The vertical projection becomes a T-shaped projection,

In order to verify the substantial increase in the moment of inertia of the circular moment tube 1b of the present invention, the inventors performed the following calculation and analysis on the circular moment tube 1b of the present invention:

The characteristic analysis is carried out by taking several circular moment tubes 1b of the same outer shape, and the characteristic curve of the circular moment tube 1b

See the meshing result of the circular moment tube 1b shown in Fig. 9 and the equivalent stress result of the circular moment tube 1b shown in Fig. 6.

Conclusion: According to the comparison, the moment of inertia of the circular moment tube 1b and the rectangular tube (basic equal circumference, h1, h2, b1, b2 are equal) increases by 10%-20%; the larger the circular moment tube h1, the smaller the global moment of inertia When taking the value, h1 should take a small value as much as possible; h2 is the moment of inertia The change of the influence is greater, and the larger the h2, the larger the moment of inertia; the contribution of other parameters to the moment of inertia is not obvious.
