Description

TECHNICAL FIELD

[0001] The utility model relates to the connecting technical field of general building structure, in particular to a composite thermal insulation keel for discontinuous wall surface. BACKGROUND

[0002] It is a common decoration method to install a decorative panel on the surface of an interior wall, and sometimes a thermal insulation board is additionally installed between the decorative panel and the wall surface to play a role of thermal insulation and sound insulation. In order to achieve the effect of fire prevention, there are non-combustible but heavy panel materials such as gypsum board in the decorative panel, which are not only heavy but also brittle, and need to be reliably connected with the wall surface. Therefore, various mechanical connecting parts are needed for installation.

[0003] If the wall surface is not to be damaged, light steel keel is a good choice for installing a thermal insulation board and a decorative panel on the wall surface, which has good bearing capacity and can provide a large number of attachment points to provide a reliable basis for subsequent gluing or corner code installation.

[0004] However, light steel keel also has its own shortcomings. First, it needs a complete wall surface as a space for building a stress frame, and if there are local gaps in the wall surface due to the need to open doors and windows or other factors, the light steel keel will not be able to bear normally (the light steel keel is usually structured with a row of vertical rods arranged between the top beam and the bottom beam, mainly relying on the vertical rods for bearing, and is not allowed to be broken). Second, the light steel keel has a high thermal conductivity, and the thermal insulation layer is usually arranged in the gap of the light steel keel, which will cause a cold bridge in the thermal insulation layer.

[0005] PET foam (polyethylene terephthalate) is a foaming material with thermal insulation effect, but it is different from conventional foaming thermal insulation materials, and it has a certain degree of mechanical strength. The panel made of PET foam can even be used to make some furniture (such as wardrobes). CONTENT OF THE UTILITY MODEL

[0006] The utility model provides a composite thermal insulation keel for discontinuous wall surface.

[0007] The technical problem to be solved is that the light steel keel cannot normally bear on the discontinuous wall surface, and it also causes a cold bridge.

[0008] To solve the above technical problems, the utility model adopts the following technical scheme: a composite thermal insulation keel for discontinuous wall surface, comprising a keel shell and a PET core filled in the keel shell, which is arranged on the wall surface in intervals and used for sticking the decorative panel to the wall surface on the discontinuous wall surface.

[0009] The keel shell is a profile steel section or an aluminum section, one side of the keel shell is connected to the wall surface by adhesive bonding; and the PET core is a foamed PET board, the PET core is connected to the inner wall of the keel shell and the veneer by adhesive bonding respectively.

[0010] Further, the gap between the veneer and the wall surface is filled with a thermal insulation board.

[0011] Further, the composite thermal insulation keels are arranged in multiple vertical columns on the wall surface and arranged in vertical joints on the thermal insulation board, and an additional composite thermal insulation keel is arranged around a position where a veneer needs to be opened.

[0012] Further, a caulking thermal insulation material is filled between two adjacent composite thermal insulation keels in the same vertical column, an aluminum foil adhesive tape is attached to the caulking thermal insulation material, and the caulking thermal insulation material is connected to the thermal insulation boards on both sides through the aluminum foil adhesive tape.

[0013] Further, levelers for adjusting the distance between the veneer and the wall surface are uniformly arranged on the wall body between two adjacent vertical columns of composite thermal insulation keels, the leveler is a circular flat box filled with thermal insulation material, the cover of the circular flat box is connected to the box body by screwing, the cover of the circular flat box is connected to the veneer by adhesive bonding, and the box body is connected to the wall surface by adhesive bonding; the circular flat box penetrates the thermal insulation board.

[0014] Further, the keel shell is a profile steel with a groove, the PET core is filled in the groove of the keel shell and is in interference fit with the groove, and the outer side of the groove bottom of the keel shell is connected to the wall surface by adhesive bonding.

[0015] Further, the surface of the PET core in contact with the keel shell is brushed with a PET primer, and the surface of the keel shell is brushed with a primer.

[0016] Compared with the prior art, the composite thermal insulation keel for discontinuous wall surface has the following beneficial effects:

[0017] In the utility model, the conventional light steel keel is cut into multiple sections and pasted on the wall surface, and then the veneer is pasted on the light steel keel, and the complete ceiling and vertical rod are no longer relied on to bear the weight, even if there is an area on the wall where the conventional light steel keel must be opened, the installation of the veneer is not affected. At the same time, the foamed PET core is clamped in the groove of the keel, the veneer is not directly connected with the light steel keel, but is pasted on the PET core, the heat conduction channel between the veneer and the wall surface is broken by the foamed PET core, and the thermal insulation effect is not weakened by the cold bridge.

[0021] As Figures 1-2 shown, a composite thermal insulation keel for discontinuous wall surface comprises a keel shell 1 and a PET core 2 filled in the keel shell 1, which is arranged at intervals on the wall surface and used for sticking a finish board 4 on the wall surface on the discontinuous wall surface;

[0022] Here, the "discontinuous wall surface" refers to the wall surface discontinuous due to door and window holes and other factors. The segmented composite thermal insulation keel glued to the wall means that it does not need to form a complete frame to effectively bear stress and can be used flexibly like double-sided tape. If it is necessary to open an avoidance opening, a few composite thermal insulation keels are arranged around the avoidance opening like the lower left corner. Figure 2 Meanwhile, it can still play the role of the skeleton of the conventional keel as the exoskeleton of the finish board 4 to support the finish board 4. In addition, the segmented composite thermal insulation keel is helpful for sticking, because it is difficult to stick a whole long keel to the wall surface without air pockets.

[0023] The keel shell 1 is a profile steel section or an aluminum section, one side of the keel shell 1 is glued to the wall surface, and the PET core 2 is a foamed PET strip, which is glued to the inner wall of the keel shell 1 and the finish board 4 respectively.

[0024] The foamed PET strip has sufficient structural strength while having thermal insulation effect, which other foamed thermal insulation materials cannot achieve.

[0025] In the embodiment, the gap between the finish board 4 and the wall surface is filled with a thermal insulation board 3. This is a commonly used installation method that can save space.

[0026] The composite thermal insulation keel is arranged at intervals on the wall surface as multiple vertical columns and is arranged in the vertical joints on the thermal insulation board 3, and additional composite thermal insulation keels are arranged around the position where the finish board 4 needs to open an avoidance opening. This is a useful installation method that is regular and can ensure sufficient structural strength.

[0027] The foamed PET strip has sufficient structural strength while having thermal insulation effect, which other foamed thermal insulation materials cannot achieve.

[0028] To improve the construction efficiency, the composite thermal insulation keel is mainly arranged in the vertical joint, and a gap exists between the two adjacent composite thermal insulation keels, and the gap will affect the heat preservation effect due to convection heat exchange, and therefore, the gap needs to be filled and sealed by the aluminum foil tape.

[0029] The wall between the two adjacent vertical composite thermal insulation keels is uniformly provided with a leveler 5 for adjusting the distance between the facing plate 4 and the wall surface, the leveler 5 is a circular flat box filled with thermal insulation material, the box cover of the circular flat box is connected with the box body in a screw connection mode, the box cover of the circular flat box is connected with the facing plate 4 in a glue joint mode, and the box body is connected with the wall surface in a glue joint mode; the circular flat box penetrates the thermal insulation plate 3.

[0030] This is a leveling structure arranged to ensure that the single facing plate 4 with a large area is installed flat, and the thermal insulation plate 3 can also be hung, see CN113266084B for details.

[0031] The keel shell 1 is a slotted profile steel, and the PET core 2 is filled in the slot of the keel shell 1 and is in interference fit with the slot, so as to ensure that the PET core 2 does not fall out before the adhesive solidifies, and the outer side of the slot bottom of the keel shell 1, that is, the bottom of the Figure 1 , has a large area and is suitable for being connected with the wall surface in a glue joint mode.

[0032] The surface of the PET core 2 in contact with the keel shell 1 is brushed with a PET primer, and the surface of the keel shell 1 is brushed with a primer.

[0033] The PET foam is a material that is not conducive to adhesion, and the PET primer here is a surface modifier on the market, which is used to improve the adhesion effect of the PET core 2. The primer is also used to improve the adhesion effect of the metal keel shell 1, and also plays a rust-proof effect on the steel keel shell 1. The primer can be an epoxy primer to form a strong paint film. In addition, all the adhesion operations in the embodiment should use MS structure glue to achieve sufficient adhesion with the PET primer and the primer.

[0034] The use method of the composite thermal insulation keel for the discontinuous wall surface includes the following steps:

[0035] Step one: paste the PET core 2 into the keel shell 1;

[0036] Step two: paste the composite thermal insulation keel and the leveler 5 on the wall surface;

[0037] Note that the order of steps one and two can be exchanged, and if water and electricity pipelines need to be installed, step two can be performed;

[0038] Step three: install the thermal insulation plate 3 and fill the gap between the composite thermal insulation keels;

[0039] Step four: stick the facing board 4 to the composite thermal insulation batten and leveler 5.

[0040] The above-described embodiments are merely preferred embodiments of the present application, and are not intended to limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements to the technical solutions of the present application made by those of ordinary skill in the art shall fall within the scope of protection of the present application as defined by the claims.
