Description

Concrete box type building module, modular building and construction method thereof

Technical Field

The invention relates to the field of buildings, in particular to an assembly type reinforced concrete box type modular combined building.

Background

Human activities emit about 510 million tons of greenhouse gases to the atmosphere every year, and the ecological damage and environmental pollution caused by global warming have irreversible and catastrophic effects on life and health of people. The carbon emission of the building in the whole life cycle accounts for a large proportion, and according to statistics, the carbon emission of the Chinese building in 2018 accounts for 51.3% of the national carbon emission, wherein the carbon emission of the building material in the production stage accounts for 28.3%, the carbon emission of the building material in the construction stage accounts for 1%, and the carbon emission of the building in the operation stage accounts for 21.9%.

The traditional construction mode of site construction has the disadvantages of high labor demand, severe construction environment for workers and poor safety; the quality and the construction period of the building are greatly influenced by factors such as constructors and weather. The material waste of the site operation is large, the construction waste is much, and the pollution is serious; the on-site construction of the main structure results in that architectural decoration, pipelines and the like cannot be prefabricated in a factory in an integrated manner with the building.

The main problems restricting the marketization popularization of the assembly type building technology are as follows: the existing box-type modular building with a concrete assembly type building, a steel structure and a wood structure is expensive in building material, multiple in building procedures and high in labor cost.

The domestic concrete box type modular building is limited to low-rise, multi-story or temporary buildings, the structural technical system is incomplete, the building safety and the building standardization cannot be guaranteed, and the factory prefabrication rate of building integration of heat preservation, pipelines and decoration is low. Several patents have been published in recent years for precast box concrete modules, modular buildings and construction methods.

The invention of "a standard integrated space module plus assembled building" of publication No. CN112031155A is the traditional practice of a single concrete box with five sides, and does not describe the structure and construction of the building assembled between modules.

The invention of the publication No. CN109138168A 'structure heat preservation integrated prefabricated concrete structure box type house and construction method' and the invention of the publication No. CN1188832A 'assembly type reinforced concrete box structure and manufacturing method' describe a method for assembling 2D plates with heat preservation, columns and concrete nodes into a 3D concrete box with five surfaces. However, the construction period is long due to field assembly, and the two patents do not solve the problem of how to combine the modules into the structure and the structure of the building.

The connection stress points among the three concrete boxes of the invention of 'flat-die precast assembled concrete box house process' of publication No. CN1022700C, 'a precast concrete box house structure system' of CN109372126A and 'sliding shockproof box building' of CN86105048 are concentrated at four corners, and the concrete boxes are not enough to resist strong external force under special conditions such as earthquake and the like, which causes the corner reinforcing steel bars to break and the concrete to crack.

The invention discloses a middle and high-rise concrete modular building structure with the publication number of CN209603286U, and the construction precision requirement of connecting boxes by prestressed steel strands is high, and the construction difficulty is high after the concrete boxes are overlapped together. The steel strands are only pulled by the side between the boxes, and the stress points are few.

The invention discloses an integral assembling method for a precast concrete box-shaped structure building, which is published under the number CN104847018A, and the cast-in-place concrete strip is positioned between an upper layer box-shaped module and a lower layer box-shaped module, construction such as template manufacturing, reinforcing steel bar binding, concrete pouring and the like is required on site, the cast-in-place concrete beam needs solidification and maintenance time as the traditional construction method, and the method loses the advantages of simple installation and high construction speed of the box-shaped structure building.

A cavity for pouring mortar is arranged on the outer side of a box wall plate of a patent with a publication number of CN 110612373A of PRE-FABRICATED PRE-FINISHED VOLUMETC CONSTRUCTION OFUILDING, a steel bar is inserted to realize vertical direction connection, the requirement on construction precision is high, and the connection strength of the cavity and a module main body is insufficient only by concrete. The building lacks a structure for resisting the shearing force of the building, and the steel plates connected horizontally are sleeved on the steel bars of the wall body, so that the wall body can be damaged by the pulling force.

The two metal groove clamping pieces of the invention with the publication number of "PPVC CONNECTOR (PPVC CONNECTOR)" of CN112119193A (CN112135948A) occupy larger wall thickness, and the main structure of the groove is only adhered by concrete, so that the holding force is insufficient. The metal grooves and other members increase the cost and the working procedure, and weaken the advantage of the space modular building. The horizontal connecting plates under the wall body need to be installed on the construction site, so that the decoration cannot be prefabricated in a factory.

The vertical connection of the upper and lower storey box building modules of the invention "prefabricated volume building modules and connectors for joining prefabricated volume building modules" under the publication No. CN109695296A adopts a common construction. Some of the joints need to be fixed by grouting on the edge of the indoor ground on a construction site, and factory prefabrication and decoration on the ground and the lower part of the wall are affected.

China already enters the aging society of the population, and the number of technical workers is reduced year by year. The construction field needs a construction method with scientific and reasonable structure, low construction difficulty, high prefabrication rate, good durability and low cost. The invention is a green and excellent carrier for assembly transformation in building industry, and has strong vitality and great development aftereffect.
