Description

Cold bridge-preventing metal composite heat-insulating plate and hanging plate structure of exterior wall enclosure system

Technical Field

The utility model relates to the technical field of building enclosure, in particular to a cold bridge-preventing metal composite heat-insulating plate and a hanging plate structure of an outer wall enclosure system.

Background

The metal outer wall enclosure system is used as an ideal coat of a steel structure building, not only has the functions of heat preservation, heat insulation, sound insulation, fire prevention, water prevention, corrosion prevention and the like, but also is a representation of building art.

At present, the cold bridge phenomenon can not be avoided at the junction of the existing metal composite board external wall board and the wall surface keel. This is because the joints of the exterior wall insulation boards and the steel structure keels are usually fixed in the form of nailing. When the metal composite board outer wall building conducts heat with the outside, the heat transfer coefficient of the nailing part is obviously larger than that of other parts. This is because the fastening screws penetrate the metal face and back plates directly to the steel structural joists, which act as heat transfer conductors with a strong heat transfer capacity, allowing heat to be transferred rapidly from these locations in a concentrated manner.

With the development of technology, the related product technology of the existing metal composite external wall panel has some structural innovations in the aspect of cold bridge prevention, and a tongue-and-groove hidden nail type composite board appears, but the whole technology still stays in a form of nailing and fixing the composite board, and the installation mode still connects the metal plate and the structural joist through self-tapping nails. The tongue-and-groove forms of various types and the measures of cold bridge prevention adopted are only different in structures of nailing positions. However, because the nailing installation mode is adopted at all, the metal outer wall surface is directly penetrated through the heat insulation plate by self-tapping nails and fixed on the steel structure keels, and the nail heads are directly exposed outside the room or are indirectly hidden in the grooves of the heat insulation plate in an inserting way, the occurrence of the cold bridge phenomenon cannot be fundamentally avoided. The metal self-tapping screw is used as a heat conductor, and a cold bridge is inevitably generated. Especially in the cold northern area of weather, indoor and outdoor temperature difference is great, and the cold bridge phenomenon is more outstanding. The appearance of cold bridge phenomenon not only affects the heat preservation effect of the building, but also greatly affects the corrosion resistance, the water resistance, the overall stability of the structure and the use effect of the steel structure building, so that the problem that the cold bridge phenomenon of the outer wall of the metal composite heat preservation plate is needed to be solved is solved.

In addition, the metal plate wall surface of nailing installation is influenced by construction factors, and the poor flatness of the plate surface can be caused, and the phenomenon of deformation, bulge and bulge after installation is caused, so that the attractive effect of the wall surface is influenced.

Again, the hidden composite sheet of screw is usually tongue-and-groove socket joint form, leads to the metal composite sheet to only follow single direction (from bottom to top) installation, also can only follow single direction (from top to bottom) dismantlement after the installation, leads to the wall to need to dismantle the wallboard locally or change wallboard locally very difficultly if need, is unfavorable for maintenance replacement. Meanwhile, the mounting mode of nailing connection enables the disassembled composite board to be easily damaged and cannot be reused.

The vertical splicing seam adopts the design of the profile decoration combined buckling strip, when overhauling or disassembling, only the butt seam combined buckling strip 40 and the butt seam supporting piece 30 in the butt seam are required to be disassembled from the outer side, and then the mounting bolts 60 of the profile clamping pieces 9 are disassembled from the inner side, so that the constraint of the shape clamping pieces 9 on the composite heat insulation board 0 is relieved, and the disassembly of the hanging metal composite heat insulation board can be completed. For the metal composite heat-insulating plate needing to be partially dismantled, the vertical butt joint combined buckling strip 40 can be dismantled from the outer side, then the metal composite heat-insulating plate is transversely slid, the constraint of the U-shaped section bar clamping piece 9 on the metal composite heat-insulating plate is relieved, and the partial wallboard can be dismantled. The transverse sliding disassembly process has no influence on the upper and lower adjacent composite insulation boards, and solves the problems of overhauling and partially disassembling the grooved and tongued nailing board. The metal composite heat-insulating board in the hanging installation of the utility model has no nailing and perforation on the board surface, thus avoiding the direct contact between the metal panel on the outer side of the wallboard and the inner side structure, fundamentally avoiding the occurrence of cold bridge phenomenon, ensuring the intact board surface after being correctly disassembled, and realizing the recycling of the metal composite heat-insulating board.

In summary, the cold bridge prevention metal composite heat-insulating board and the hanging board structure of the exterior wall enclosure system provided by the utility model have the advantages that the core material filled in the middle of the hanging type cold bridge prevention metal composite heat-insulating board is rock wool with a high-density fireproof heat-insulating structure, and the peripheral frames are all sealed by adopting bridge-cutoff heat-insulating profiles, so that the real bridge cutoff of the composite board is realized. The hanging plate structure adopts a novel composite hanging plate shape of hanging buckling, and the hanging construction process ensures that the metal wallboard surface is not nailed or perforated, and can ensure the integrity of the metal composite board. The wallboard after installation has high surface flatness and better appearance effect, and also avoids the cold bridge phenomenon caused by the connection of the traditional metal composite board and the steel structure keels by adopting screws/self-tapping nails, thereby improving the beautiful and environment-friendly energy-saving effects of the metal composite board outer wall surface system and realizing the functions and assembly type requirements of the novel metal composite outer wall enclosure system, such as heat preservation, heat insulation, sound insulation, fire prevention, water prevention and decoration integration. The utility model adopts the hanging type mounting technology to ensure that the metal composite heat-insulating plate is convenient to mount and dismount, the wall plate which is correctly mounted and dismounted is free from damage and can be reused, the cold bridge problem existing in the traditional metal external wall plate system is solved, and the problem that the external wall plate can not be partially dismounted, replaced and dismounted and then damaged is solved.
