Description

A type of Z-shaped steel

technical field

The utility model relates to the construction field, in particular to a Z-shaped steel.

Background technique

Z-shaped steel is a common cold-formed thin-walled steel, the thickness is generally between 1.6-3.0mm, the section height is mostly between 120-350mm, and its processing materials are hot-rolled (painted), galvanized, and its processing standards are as follows: GB50018-2002 implementation, Z-shaped steel is usually used in large-scale steel structure workshops, and its processing length and holes are produced according to processing requirements.

C-shaped steel is processed by hot coil and cold bending. It has thin wall, light weight, excellent section performance and high strength. Compared with traditional channel steel, it can save 30% of materials with the same strength.

Most of the existing roof purlins use C-shaped steel and Z-shaped steel with equal cross-section. The steel consumption of C-shaped steel is relatively large, and the installation of Z-shaped steel with equal cross-section is complicated.

Therefore, in view of the above problems, it is necessary to design a new Z-shaped steel to make up for the above defects.

Utility model content

In order to solve the above-mentioned defects, the utility model proposes a Z-shaped steel, which is a Z-shaped steel with a variable cross-section, which reduces the weight of the Z-shaped steel and avoids the cumbersome installation of the Z-shaped steel.

The technical scheme of the utility model is achieved in that:

A Z-shaped steel, which includes a web, an upper wing and a lower wing; the upper wing and the lower wing are vertically connected to the two ends of the web respectively, and the extension directions of the upper wing and the lower wing are opposite; the upper wing The width of the plate is greater than the width of the lower wing.

Wherein, the width of the upper flange and the width of the lower flange are both smaller than the height of the web.

Wherein, the end of the upper flange away from the web is further provided with a first supporting steel body.

Wherein, the end of the lower wing away from the web is further provided with a second supporting steel body.

Wherein, the upper wing plate and the lower wing plate are integrally formed with the web plate.

Compared with the prior art, the utility model has the following advantages:

The cross-sectional size of the upper wing plate of the utility model is larger than that of the lower wing plate, and the purpose of saving steel consumption and construction time is achieved by changing the size of the cross-section; in addition, the Z-shaped steel of the utility model is integrally formed, so the entire Z The steel body of the section steel has no weld seam, so its compressive capacity is stronger, its flexural bearing capacity is stronger, and it has better supporting capacity. During use, when it bears a large pressure, it rarely breaks or deforms The phenomenon makes the quality and performance of Z-shaped steel better, and can be widely applied to high-strength load-bearing support fields such as building steel structures, mechanical equipment, and bridge engineering.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description These are only some embodiments of the utility model, and those skilled in the art can also obtain other drawings based on these drawings without creative work.

Fig. 1 is the structural representation of the utility model Z-shaped steel;

Fig. 2 is a structural schematic diagram of another angle of the Z-shaped steel of the present invention.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Referring to Fig. 1 and Fig. 2, a kind of Z steel, it comprises web 1, upper wing 2 and lower wing 3; The extension directions of the wing plate 2 and the lower wing plate 3 are opposite; the width B1 of the upper wing plate 2 is greater than the width B2 of the lower wing plate 3 . The width of the upper wing plate of the utility model is greater than that of the lower wing plate, and the bearing capacity of the upper wing plate is greater than that of the lower wing plate, so the Z-shaped steel of the utility model is not easily deformed during use; in addition, the two ends of the Z-shaped steel It is made into cross-sections of different sizes, which is convenient for on-site installation and is not easy to be confused.

Wherein, the width B1 of the upper wing 2 and the width B2 of the lower wing 3 are both smaller than the height H of the web 1 .

Wherein, the end of the upper wing 2 away from the web 1 is further provided with a first supporting steel body 21, and the angle between the first supporting steel body and the upper wing of the utility model is 45 degrees or other angles, and is used as a support.

Wherein, the end of the lower wing plate 3 far away from the web 1 is further provided with a second supporting steel body 31, and the second supporting steel body of the utility model forms an angle of 45 degrees or other angles with the lower wing plate, and is used as a supporting member.

Among them, the upper wing plate and the lower wing plate are integrally formed with the web plate, and the Z-shaped steel of the utility model is integrally formed, so the steel body of the entire Z-shaped steel has no weld seam, so its compressive capacity is stronger, and its bending bearing capacity is strong , with better supporting capacity, in the process of use, when it bears a large pressure, it rarely breaks or deforms, which makes the quality and performance of Z-shaped steel better, and can be applied to construction steel on a large scale High-strength load-bearing support fields such as structures, mechanical equipment, and bridge engineering.

When the utility model is used in practice, the web mainly plays the role of receiving and transmitting force as the middle plate. The upper and lower wings need to have a strong bearing capacity. After the entire Z-shaped steel is erected, the web is vertical to the ground, and the size of the web between the upper and lower wings is the size of the web. height, the dimension on the extension surface of the upper or lower wing is its width; and the dimensions in the same width direction of the upper wing, lower wing and web are the width of the upper wing and lower wing respectively.

Take the Z-shaped steel of specific model as example, as shown in table 1 below, it is the size table of various Z-shaped steels of the utility model;

Table 1

The utility model achieves the purpose of saving steel consumption and construction time by changing the size of the section, and the utility model reduces the weight of the Z-shaped steel and avoids the defect that the installation of the Z-shaped steel is complicated.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.
