Problems solved by technology

[0003] At present, my country's prefabricated buildings have not systematically solved the above research topics, or there are areas for optimization and improvement; The vertical components of the tube connection have not been solved to meet the same performance requirements as the cast-in-place structure. The process precision of the sleeve connection steel bar is high, the butt joint of the hoisting steel bar is troublesome, there are many construction links, and the cost is high; there is no breakthrough in the assembly. The lower part must be assembled before the upper part can be hoisted. The construction mode of the traditional thinking, the assembly and construction time is long, it is difficult to realize the design principle of "strong nodes, weak components", and it is impossible to meet the same performance requirements of the assembly structure and the cast-in-place structure

Embodiment 1

[0060] Such as Figure 1-4 As shown, the prefabricated prefabricated concrete structure construction method of this embodiment does not include the construction of prefabricated building wall panels, and the specific steps are:

[0061] a. Design general assembly drawings and prefabricated components to make construction drawings, produce prefabricated structural components according to the requirements of the design drawings and transport them to the site;

[0062] b. (this is the operation of entering the next construction layer N+1 after the last assembly construction layer N is completed), install the vertical support 8 and the required formwork 7 for supporting the horizontal member. The installed support 8 and formwork 7 are required to meet the precise elevation requirements, and the loads of the connected vertical members on the installed horizontal members are required to be considered;

[0063] c, hoisting the prefabricated composite beam 2 and the prefabricated flo...

Embodiment 2

[0072] Such as Figure 2-6 As shown, the prefabricated building wall panel 11 is also assembled and constructed during the structure construction and assembly stage of the prefabricated concrete structure construction method of this embodiment, and the specific steps are:

[0073] a. Design general assembly drawings and prefabricated components to make construction drawings, produce prefabricated structural components and prefabricated building wall panels 11 according to the requirements of the design drawings and transport them to the site;

[0074]b. (this is the operation of entering the next construction layer N+1 after the last assembly construction layer N is completed), install the vertical support 8 and the required formwork 7 for supporting the horizontal member. The installed support 8 and formwork 7 are required to meet the precise elevation requirements, and the loads of the connected vertical members on the installed horizontal members are required to be consider...

Abstract

The invention discloses an assembled concrete structure construction method. According to the construction method, a reversed construction procedure is adopted for installation of a vertical component of a currently constructed floor, that is, before connection assembly of a horizontal component of the currently constructed floor, the vertical component connected to the upper portion of the horizontal component is hoisted firstly, and finally connection concrete is poured at a time to connect the horizontal component with the vertical component of the currently constructed floor into a whole. The construction method adopts the reversed construction procedure, so that construction links are reduced, and the construction period is shortened; the method is suitable for assembled concrete building construction for structure systems such as precast shear walls, composite wallboards and frameworks, and has the advantages of convenient construction, time saving, economy, environment friendliness and the like; and meanwhile, the requirement for identical performance as a cast-in-place structure is met.

Description

technical field [0001] The invention relates to a prefabricated concrete building construction technology, belongs to the field of building industrial production, and specifically relates to a construction method of a prefabricated concrete structure. Background technique [0002] The country proposes the future development direction of the construction industry of smart cities, green buildings and construction industrialization; and proposes that in about 10 years, the proportion of prefabricated buildings in new buildings will reach 30%; therefore, the Ministry of Science and Technology issued the "Green Building and Construction Industrialization" key The specific notice of the special 2016 annual project declaration guide mentioned the research content of the subject (excerpted part of the content related to the present invention): the study proposes a new series of connection node forms, which meet the same performance requirements as the cast-in-place structure; it is s...
