The present application relates to a kind of high security assembled building lifting appliance, including sling and several hooks, the sling includes main sling and several auxiliary slings, balance beam is arranged between the main sling and auxiliary sling, the auxiliary sling is arranged at the corner of balance beam, the hook is connected at the bottom end of auxiliary sling.The present application is connected with embedded lifting bar on cross laminated timber by hook, presses ring beam to make suction disc contact cross laminated timber top surface, starts vacuum pump to discharge air in suction disc, under the action of atmospheric pressure, suction disc tightly adsorbs cross laminated timber, not only embedded lifting bar is stressed, surrounding area also bears lifting load due to the adsorption of suction disc, greatly reduces the working pressure of embedded lifting bar, also expands the stress range of plate body during lifting.Also avoid the problem of stress concentration at lifting point, far from the deflection of lifting point is too large.Meanwhile, the stability of lifting object is strengthened by the damping effect of balance beam and the cooperative work of many lifting points, and the operation difficulty of in-place is reduced.

The present invention introduces a novel approach to sound absorption in cross-laminated timber (CLT) panels by integrating acoustic absorption into the bottom ply. This eliminates the need for external sound absorbing finishes which are costly and obscure the exposed wood aesthetic. Comprised of channels filled with sound-absorbing material, the absorbers target a broad range of frequencies relevant to architectural applications. This feature is incorporated within the standard CLT lay-up and glueing process. By strategically removing material where it minimally affects panel strength, the CLT panels maintain robustness as a structural member, enhancing room acoustics while preserving the natural wood aesthetics and structural qualities of CLT. In architectural and construction contexts, this integration of acoustic absorption offers a practical and efficient solution to a known limitation of mass timber construction.

The joint further comprises two wedges (30) where upon assembly of the two adjacent wall panels (1) both wedges (30) can be inserted into the wedge space (93) forming an interference fit between both wedges (30) and both wall panels (1).

A composite flooring structure (100) combining cross-laminated timber and a concrete topping is disclosed The structure includes a structural beam (105) comprising a top flange (110), bottom flange (115), and web structure (120), with reinforcing bars (150) embedded to provide tensile strength and structural reinforcement. A plurality of cross laminated timber slab bands (125) are positioned on either side of the beam, fastened with 10x300 mm screws (130), and features a five-ply configuration (125,155). A surface layer (135) of high-performance concrete (140), 50mm thick, is applied to enhance load distribution and rigidity. An interface layer (145), consisting of grout material, fills micro-gaps between the cross laminated timber slab bands and the concrete topping. A web opening (160) positioned along the structural beam, adapted for a passage of utilities. This composite structure provides improved structural integrity, load-bearing capacity, and durability, making it suitable for a wide range of flooring applications.
