Novel H-shaped steel beam of unequal-flange steel-concrete combined corrugated web and manufacturing method thereof

Abstract

The invention discloses a novel H-shaped steel beam of an unequal-flange steel-concrete combined corrugated web. The novel H-shaped steel beam comprises an upper flange plate, a lower flange plate, a corrugated web, a tie stirrup, a gusset plate and concrete, wherein the upper flange plate and the lower flange plate are arranged in parallel at an interval, the two opposite edges of the corrugated web are fixedly arranged on the upper flange plate and the lower flange plate correspondingly, the width of the upper flange plate is smaller than that of the lower flange plate, one end of the tie stirrup is fixedly arranged on the lower flange plate, the other end of the tie stirrup is fixedly arranged on the end, away from the lower flange plate, of the corrugated web, the gusset plate is fixedly arranged on the upper flange plate, and the concrete is poured between the gusset plate and the lower flange plate. The invention further provides a manufacturing method of the novel H-shaped steel beam of the unequal-flange steel-concrete combined corrugated web. The novel H-shaped steel beam has the beneficial effects that the steel consumption and the welding workload are reduced, so that steel is saved, and economic benefits are increased; and the construction is easy and convenient, the integrity of beams and floors is enhanced, the pouring of a large number of post-pouring sections is avoided, and the construction efficiency is greatly improved.

Description

[Technical field] [0001] The present invention relates to the technical field of building materials, and more particularly to a new type of unequal flavor steel mixed combined corrugated belt H-steel beam and its production method thereof. 【Background technique】 [0002] my country has vigorously promotes the transformation of traditional buildings to industrial building. In traditional buildings, most of the work needs to be completed in construction site, long construction period, severe environmental pollution, large lapsen, and shortage of construction staff, etc. have become a barrier in suppressing the progress of building industries. Although the assembled building has the advantage of high construction level, there are still some non-negligible issues, such as the reliability of the PC structure vertical nodes, steel and combined structural enclosures, etc., and it is usually The cost is high, leading to the owner, and the user is not good to assemble the assembled satisf...

AI Technical Summary

Problems solved by technology

In traditional buildings, most of the work needs to be completed on the construction site. Problems such as long construction period, serious environmental pollution, large stockpiling site, and shortage of construction personnel have become barriers to the progress of the construction industry.

Although the prefabricated building has a higher construction level advantage, there are still some problems that cannot be ignored, such as the reliability of the vertical joints of the PC structure, cracking and water leakage of the enclosure wall of the steel and composite structure, etc., and it is usually The cost is relatively high, resulting in poor satisfaction of owners and users with prefabricated structures, and it is difficult for developers to actively choose prefabricated structures under the promotion of policies

[0003] Although the steel structure has a relatively reliable joint structure and its construction quality is easy to guarantee, the single boundary trench itself has problems such as poor sound insulation and heat insulation, low stiffness and poor comfort, and additional fire prevention and anticorrosion treatment is required, which must be overcome in residential buildings. difficulties

The steel-concrete composite structure has the advantages of the above two structures. Most of its main body is covered with concrete and has the same connection nodes as the steel structure. It perfectly overcomes the shortcomings of the steel structure and the PC structure, but still has the steel consumption The higher problem, the H-shaped steel beam in the steel-concrete composite beam mainly bears the bending moment, and the best way to improve the bending bearing capacity is to increase the height of the web and reduce the thickness of the web, but the web is under the action of shear force It is easy to buckle, and its deformation is not easy to control during transportation and installation. In order to improve the shear bearing capacity and stiffness of the member, it is generally necessary to increase the thickness of the web or set stiffeners to improve the stability of the web, which increases the The amount of steel used for the components is increased, and the construction workload is increased.
