The first connecting part 42 of the cross keel of the first connecting piece 4 is embedded in the groove of the first cross keel 11; specifically, two side portions 422 of the first connecting portion 42 of the cross keel are respectively tightly attached to two side portions 112 of the first cross keel 11, and a middle portion 421 of the first connecting portion 42 of the cross keel supports the two side portions 112 of the first cross keel 11. The two side portions 212 of the first mullion 21 have inwardly bent folded portions 213 along the sides thereof, the width of the folded portions 213 is approximately 1/6-1/5 of the width of the first mullion 21 (i.e. the distance between the two side portions), and the two first clamping portions 43 of the first connecting member 4 respectively clamp the two folded portions 213. The mullion first connecting portion 41 is fixedly connected to both side portions 212 of the first mullion 21 by fasteners 45 (preferably pull rivets), and the cross keel first connecting portion 42 is fixedly connected to both side portions 112 of the first cross keel 11 by fasteners 46 (preferably pull rivets).

The technical effects of the flange portion 213 and the second clamping portion 53 are the same as those of embodiment 2, and are not described herein again. In addition, because the middle 521 of the second connecting portion 52 of the cross keel supports the groove bottoms of the two third cross keels 31, and the side edges 522 of the two side portions 52 of the second connecting portion 52 of the cross keel are tightly attached to the two groove walls of the corresponding third cross keels 31, i.e. there is no structural gap between the second connecting member 5 and the two third cross keels 31 in the longitudinal direction and the transverse direction, the second connecting member 52 of the second connecting member 5 does not move or shift relative to the two third cross keels 31, i.e. the integral structure formed by the second connecting member 5 and the two third cross keels 31 is stable and reliable, the fixed connection between the first vertical keel 21 and the cross keel assembly 3 (the two third cross keels 31) is also stable and reliable, so that the structural stability and the integral structural strength of the rectangular frame structure formed by the first vertical keel 21, the second vertical keel 22 and the two cross keel assemblies 3 are better, therefore, the rectangular frame structure and the sound-insulation and heat-preservation material assembled and filled in the rectangular frame structure are reliable, and the sound-insulation and heat-preservation functional unit formed by combining the rectangular frame structure and the sound-insulation and heat-preservation material is reliable.

The second connecting member 5 is of an integral structure and is disconnected at the middle position of the middle portion 521 of the transverse keel second connecting portion 52, specifically, the second connecting member 5 is formed by bending a light steel plate for multiple times through a cold bending process, two disconnected ends of the middle portion of the transverse keel second connecting portion 52 are provided with second bending portions 54 extending inwards, a clamped sound insulation and shock absorption pad 57 is arranged between the two second bending portions 54, and the three are tightly attached and fixedly connected through a fastener (optionally a screw). On one hand, the two second bending parts 54 structurally increase the cross-sectional stress area of the middle part of the second connecting part 52 of the cross keel, play a role in buffering and distributing the acting force for extruding the two third cross keels 31, and can prevent the middle part of the first connecting part 42 of the cross keel from bending; on the other hand, from the function cross keel second connecting portion 52 is a whole, for supporting two third cross keels 31, from the structure cross keel second connecting portion 52 be two solitary partial fixed connection and form, consequently, certain dislocation distance is allowed along second cross keel 12 length direction in structural disconnection department, possess certain buffer room and do not suffer structural damage such as bending deformation when bearing great normal stress, even the structure of first vertical keel 21 takes place to damage or even warp, lead to two third cross keels 31 to take place slight dislocation along its length direction, because cross keel second connecting portion 52 itself can not take place to warp crooked, the connection between its two lateral parts and two corresponding third cross keels 31 is still reliable and stable, thereby can not cause too big influence to the fixed connection of two third cross keels 31 and first vertical keel 21. The soundproof and shock-absorbing pad 57 between the other two second bent portions 54 not only functions to further buffer the force of pressing the two third cross runners 31, but also prevents the occurrence of an acoustic bridge.

In addition, the two sides of the middle part 521 of the second connecting part 52 of the cross keel, which is located outside the two third cross keels 31, are provided with extending parts 521A extending outwards, i.e. the middle part 521 is made to be cross-shaped, and the extending parts 521A are in contact with the two side parts 312 of the third cross keel 31, on one hand, the extending parts 521A can play a role of supporting a similar support frame to enhance the resistance of the cross keel assembly to being squeezed, and on the other hand, the areas of the middle part 521 and the second bending part 54 are correspondingly widened to further enhance the acting force. Considering that the extension 521A is easily damaged locally due to the perpendicular direct contact with the two side portions 312 of the third cross member 31, an elastic pad 321A is disposed at the position where the two side portions 312 contact with the extension 521A to solve the problem, and the elastic pad 321A may be fixed to the side portion 312, in which case the elastic pad 321A needs to have a certain width to prevent the elastic pad from contacting with the extension 521A after slight misalignment occurs, and the elastic pad 321A may be disposed in a clip-like structure and clamped on the extension 521A.

The side surface of the first mullion 21 (the outer surface of the middle portion of the first mullion 21) has a groove extending along the length direction thereof, and the structural relationship between the groove and the second connection portion 51 of the mullion is the same as that between the groove and the first connection portion 41 of the mullion in embodiment 2, and is not described herein again.
