The disclosure relates to the technical field of building construction, and provides a connecting member, an ALC batten mounting node structure, and a prefabricated mounting method. The connecting member includes a connecting part, a first pipe clamp, and a second pipe clamp. The connecting part includes a first connecting segment and a second connecting segment, the first pipe clamp and the second pipe clamp are respectively perpendicular to the first connecting segment, and symmetrically arranged on opposite sides of the first connecting segment, and the second connecting segment is bent towards one side of the first connecting segment. According to the ALC batten mounting node structure having the connecting member, the first connecting segment is located between a first ALC batten and a second ALC batten which are adjacent, the first pipe clamp is embedded in the first ALC batten, and the second pipe clamp is embedded in the second ALC batten; and the second connecting segment is configured for connecting a steel beam, achieves the effect of using the connecting member on a node position for simultaneously fixing the two adjacent ALC battens, enables fixation to be firmer, and enables a mounting process to be more convenient. The prefabricated mounting method based on the ALC batten mounting node structure can achieve sequential mounting of the ALC battens.

A wall panel includes a first and second planar skins and a core disposed therebetween. A first and second lateral edge extends between the skins. The second lateral edge comprises a female receiver. The first lateral edge comprises a male extension extending therefrom. The female receiver is formed in the core and has a depth equal to or greater than a length of the male extension. The male extension is formed from the core comprises a first parallel surface extending parallel to and offset from the first planar skin and a second parallel surface extending parallel to and offset from the second planar skin. A first tapered portion comprises a first tapered surface extending at an angle relative to a longitudinal axis from the first parallel surface to a rounded end, and a second tapered surface extending at the angle from the second parallel surface to the rounded end.

Described herein is an acoustic structural panel having a first exposed major surface opposite a second exposed major surface and side surfaces extending between the first and second exposed major surfaces, the acoustic structural panel comprising a first protective layer comprising at least a portion of the first exposed major surface, a second protective layer comprising at least a portion of the second exposed surface, a core structure located between the first and second protective layers, the core structure comprising, a foam body; and a fibrous body, wherein the first major exposed surface of the acoustic structural panel comprises a plurality of apertures exposing the fibrous body.

A panel comprises a swellable sealing lip. The panel comprises a panel top side and a panel bottom side and at least four panel edges arranged mutually facing each other in pairs, with complementary retaining profiles provided in pairs at the mutually facing panel edges, wherein the retaining profiles are configured such that at a retaining profile of one panel further panels with a complementary retaining profile can be mounted. In this case, at least one retaining profile comprises a swellable sealing lip at least partially along its longitudinal axis. Moreover, an arrangement of such panels and a method for producing such panels are proposed. In summary, the above-described panel has the advantage that panel joints can be protected against ingress and penetration of liquids in a particularly good and easy way without applying permanent, additional stresses to the connection of joined retaining profiles.
