The specific connection method for assembling the integrated room module unit and the coupling unit in the coupled modular assembly type steel structure house comprises the following steps:
(1) the number of columns directly across and across from the integrated room module unit is noted and the layout of the existing SI, or SIV situations is determined. Before connecting the integrated room module units by using the articulated arm units, the numbers of opposite faces and opposite columns of the integrated room module units are labeled, wherein the opposite faces and the opposite columns are defined as follows, two faces closest to each other between two adjacent integrated room module units A, B are defined as opposite faces (PA, PB) of the two integrated room module units, the two adjacent integrated room module units (A, B) refer to two modules closest to the center of the integrated room module unit, two structural columns (ZA 1, ZA 2) exist in the opposite faces PA, two structural columns (ZB 1, ZB 2) exist in the opposite faces PB, when the planes of ZA1 and ZB1 or ZB2 are vertical to the PA, ZB1 or ZB2 is called as the opposite column of PA, ZA1 is called as the corresponding column of the opposite column of PA, and similarly, when the planes of ZA2 and ZB1 or ZB2 are vertical to the plane of PA, ZB1 or ZB2 is called as the opposite column, ZA2 is called the corresponding column of the pair, then for any pair P there is any number of pairs of columns of 0, 1, 2, and PA and PB are the number of pairs of columns as shown in table 1;

For the four cases, the situation S iii can be avoided by a rational layout of the integrated room module units, so that only three cases S i, S ii and S iv need to be considered when connecting the integrated room module units with the limb coupling units.
(2) When the connecting limb unit is adopted to connect the integrated room module units, the connecting limb unit is required to be connected according to the sequence of firstly connecting the S I and then connecting the S II, namely, after connecting all the front columns under the S I situation in the integrated room module units in the layout through the connecting limb unit embedded connecting limb beam, then connecting the front columns under the S II situation, for the S I situation, 4 end parts of the connecting limb unit embedded connecting limb beam can be directly connected with the top end parts of 4 structural columns through high-strength bolts respectively during connection; case SII also includes two cases, assuming that the front-to-back PA width is greater than front-to-back PB, SII1When the projection of the non-right column of the PB surface on the PA surface is positioned in the range of the right opposite surface PA, the right opposite surface PA and the PB are positioned on the same side of a plane formed by the two right opposite columns, and the SII2When the projection of the non-opposed cylinder of the PB surface on the PA surface is outside the range of the opposed surface PA, the opposed surfaces PA and PB are on opposite sides of the plane formed by the two opposed cylinders, in case SII1At the moment, the connection between two structural columns on the opposite surface PB and the integrated room module unit A needs to be preferentially met by the limb connecting unit according to the principle of 'cantilever minimization', namely, the beam end of a first limb connecting beam of the limb connecting unit needs to be connected with the top ends of two opposite columns through high-strength bolts respectively, the first end of a second limb connecting beam is connected with the top end of a structural column on the PB, which is not opposite to the columns, through the high-strength bolts, the second end of the second limb connecting beam is connected with the structural beam on PA through the high-strength bolts, and meanwhile, a node which is not connected with the limb connecting unit exists on PA; for case SII2In the actual design process, the situation has obvious separation effect on two adjacent integrated modules and is not beneficial to the continuity of building functions, so that the situation STII2Are avoided in the design process.
(3) When all cases SI and SI have been connected, the number of open structural columns on opposite sides of case SIV is usually not more than 2, and in this case, the connection can be made by selecting the appropriate type of coupling unit according to the rule of proximity.
(4) The building space outside the module area and the coupling area is filled with the integrated floor slabs, so that all the floor slabs form a complete plane structure, and the integrity of the house is ensured.
(5) And assembling auxiliary units such as balcony modules, sloping roof modules, integrated wallboard units and the like.

The calculation analysis can adopt a frame structure, a frame-support structure or a frame-shear wall structure as a mechanical model, and can carry out design and calculation by adopting general commercial design software according to the current structural design specification, thereby being convenient for engineering application.
The integrated room module unit that allies oneself with limb modularization assembled steel structure house through allies oneself with limb unit spelling interval arrangement, when keeping the high integrated advantage of modularization building, avoided the repeated extravagant scheduling problem of structural component of traditional modularization building stoplog, column, biplate ingeniously, can show the increase and construct usable floor area.
The structural form of the 'single beam and single column single plate' of the coupled modular assembly type steel structure house also overcomes the defects of large structural integrity difference and the like caused by the difficulty in cooperative work of laminated beams and side-by-side columns of the traditional modular building, reduces the difficulty in connecting beam-column joints, and greatly facilitates the field assembly of modules.
The highly integrated coupling unit with the easily adjustable size is introduced into the traditional modular building, so that the building design requirements of more plane layouts and vertical body types can be met, and the diversified building function target of the modular building can be better realized.
