Technical Field

The utility model relates to an aluminium veneer with insulation construction.

Background

At present, the metal plate curtain wall mainly uses an aluminum veneer, an aluminum-plastic composite plate or an aluminum honeycomb plate as a basic component, wherein the aluminum veneer and the aluminum-plastic plate are most commonly used. The conventional aluminum veneer is generally formed by punching a single-layer aluminum plate, then other accessories are arranged on the punched workpiece, and then a paint system is prepared on the workpiece on which the accessories are arranged by adopting spraying or rolling, and the finished product is called the aluminum veneer.

Fig. 1 is a schematic view of a back side structure of a known aluminum veneer, generally speaking, the front side of the aluminum veneer is a decorative surface, and requirements on paint systems and regularity on the geometric shape of a plate surface are high, and therefore, a structure for fixing the aluminum veneer or a structure for installing other accessories is generally arranged on the back side of a plate body 6 of the aluminum veneer, such as four back side flanges 4 shown in fig. 1, corner connectors 3 fixed on the back side flanges 4 through rivets 1, and reinforcing ribs 5 fixed on the back side of the plate body 6 through screws 7. The aluminum veneer belongs to the thistle board to be used for the outer wall more, the aluminum veneer carries out fixed connection through 3 and the fossil fragments of mating formation on the outer wall of angle sign indicating number or other structures, because of there is the cold bridge by self, the heat preservation is not done usually to the aluminum veneer. However, with the development of the technology and the improvement of the current requirement on the heat insulation of the external wall, part of the aluminum veneers can also be compounded with heat insulation materials, which are integrally called heat insulation aluminum veneers, to form a part of the heat insulation system of the external wall, so that the heat insulation effect of the external wall is integrally improved.

Chinese patent document CN205189310U discloses an aluminum veneer, which includes an aluminum plate (i.e., a plate body) and corner connectors mounted on the aluminum plate, wherein the aluminum plate is divided into two filling cavities by reinforcing ribs, and then an aluminum pressing plate is provided for each filling cavity, and a sliding groove for the aluminum pressing plate to slide is provided between the front and rear walls of the reinforcing ribs and the aluminum plate, and mineral wool is filled between the aluminum pressing plate and the aluminum plate, thereby forming a heat-insulating aluminum veneer. In order to meet the requirement of filling mineral wool, a filling channel needs to be reserved, the area of the aluminum pressing plate is relatively small, the mineral wool is difficult to fix by using the aluminum pressing plate after the mineral wool is filled, particularly, the mineral wool is easy to fall off in the transportation process, although the mineral wool is essentially required to be filled after the mineral wool is transported in place, the mineral wool is filled under the non-factory condition, the efficiency is low, the consistency is relatively poor, and the requirement on the requirement is high. Particularly, the filling needs to have certain compactness, the strength of the aluminum veneer is low, and the operation of demanders without factory-end assembly experience on site is improper, so that the plastic deformation of the aluminum veneer is easy to generate, and the integral apparent quality is influenced.

Chinese patent document CN207776323U discloses a heat insulation aluminum veneer, which comprises an aluminum veneer body, wherein a side plate with corner connectors is disposed on the outer side of the aluminum veneer body, reinforcing ribs are disposed on the inner side of the aluminum veneer body, and a pressing cap is further disposed on the inner side surface of the aluminum veneer body. The aluminum veneer body limited by the aluminum veneer body is of a multilayer structure and comprises a protective layer, a heat insulation layer and a baffle plate, wherein an adjusting bolt matched with a pressing cap penetrates through the baffle plate, the heat insulation layer and then is embedded into a groove formed in the surface of the protective layer, the adjusting bolt is adapted to the groove and is a fixing plate, a fixing mode is not specified, the current structure for fixing the type of aluminum veneer body is welding, and the welding structure is reliable in fixing, but easily causes deformation of an aluminum or aluminum alloy plate body, so that the whole decorative effect is influenced. Because the strengthening rib is located the dorsal part of aluminium veneer body, the both ends and the curb plate fixed connection of strengthening rib can make aluminium veneer thickness bigger on the whole, and the curb plate width is also bigger to the strengthening rib is fixed for both ends, unsettled between with aluminium veneer body, does not have the additional effect to aluminium veneer body, if attach for example the bolt again and in order to produce the connection in unsettled department, inevitable can increase the quantity of fastener and to the destruction of aluminium veneer body intensity (need the fluting).

Chinese patent document CN204386084U discloses an aluminum alloy decorative plate with an overall closed structure, wherein a box structure is constructed by an aluminum alloy body, and a thermal insulation material is filled in the box structure. Because the area of the decorative surface of the heat-insulating plate is larger, the depth of the adaptive box-type structure is larger, and the heat-insulating material is relatively difficult to fill. If a foaming type heat insulation material is adopted, the filling degree of the material cannot be directly observed.

Detailed Description

Referring to fig. 1 of the specification, a schematic structural diagram of a known aluminum veneer is shown, although there are structural differences between different aluminum veneers due to different installation positions, configurations and applicable objects, in terms of structural configuration, the base structure is completely the same, and it is inevitable to include a plate body 6, the plate body 6 is generally a rectangular plate, in an installation state, one surface facing an installation base such as a wall side is a back surface or may also be referred to as an inner surface and a back surface, and the surface opposite to the back surface is a front surface, an outer surface or is referred to as a front surface, wherein the front surface is generally a decorative surface and is mostly a paint system.

In the case of paint systems, which in some applications will be referred to as paint films, generally comprise a chromized layer, a primer layer, a topcoat layer, a finishing layer, the number of paint layers and functional layers being adapted to the application. For the back side, a back paint layer is also generally present for corrosion protection.

The paint layer needs to be sprayed or roll-coated after the aluminum veneer base body is partially molded, the surface quality of the aluminum veneer base body influences the apparent quality of the final paint layer, and the apparent quality is one of important indexes of the decorative plate.

Because the heat preservation layer is prepared on the aluminum veneer after the paint system is prepared, the preparation of the heat preservation layer needs to avoid or reduce the influence on the paint system as much as possible.

It is important to note that as the technology advances, the number of layers of the paint system increases and the overall thickness of the paint system is relatively thick, whereas it is known that the thicker the paint system, the more brittle it becomes. If the plate body 6 is plastically or elastically deformed, it may cause the paint system to crack or fall off.

In addition, the decorative panel is usually mounted vertically, and in the structure shown in fig. 2, the side of the panel body 6 where the upper side plate 10 is located is the upper side thereof, and the side of the panel body where the back-side burring 4 welded to the reinforcing bead 5 is located in fig. 3 is the left and right sides.

Fig. 2, 3, 4 and 7 generally illustrate the process of installing or preparing insulation and reinforcement 5 on an aluminum veneer. The thickness of a common aluminum veneer is thinner, the thickness of a plate body 6 is more than 3mm, the thickness can be increased or decreased according to different applications, if a welding mode is adopted for installing the reinforcing rib 5, the weldability of a thin piece (the thickness of a welding piece is less than or equal to 3mm and is classified as the thin piece) needs to be considered, particularly the influence on a decorative layer needs to adopt the welding condition that the welding current is less than or equal to 70A and the welding rod is less than or equal to phi 2.5mm, and the welding current is controlled to be 50-55A during overhead welding.

If a welding connection structure is adopted between the back-side flanging 4 and the reinforcing rib 5, the distance between the welding line 13 and the plate body 6 is not less than 5mm, so that the influence of welding on a paint layer is reduced.

If a welding connection structure is adopted between the back-side flanging 4 and the reinforcing rib 5, the back-side flanging 4 is sprayed with the anticorrosive paint in a spraying mode after welding is finished, and the paint layer is not coated in advance.

As mentioned above, the plate body 6 of the aluminum single plate is generally a rectangular plate, and according to different configurations, there is generally a pair of sides provided with the back-side flange 4, the back-side flange 4 and the plate body 6 are generally integrally formed by stamping a plate material, and the back-side flange 4 and the plate body 6 are bent by using a side line of the plate body 6 as a folding line.

In the construction shown in fig. 10, there are three back side flaps 4, whereas in the construction shown in fig. 9 there are two back side flaps 4, each back side flap 4 being provided with an angle brace 3. The structure shown in fig. 2, 3, 4 and 7 has three back-side flanges 4, and corner connectors 3 are provided on the left and right back-side flanges 4. In some embodiments, there may also be four back side cuffs 4, each back side cuff 4 being provided with corner braces 3, either the left and right back side cuffs 4 or the upper and lower back side cuffs 4. This is common knowledge in the art and will not be described further herein.

The corner brace 3 is not a standard component, but has substantially the same structure, namely a 90-degree corner component, a rivet hole is formed in one plate surface of the corner component, and the corner component is fixedly arranged on the corresponding back-side flange 4 through a rivet 1.

The other plate surface of the corner fitting is provided with a fixing hole 2 for mounting the aluminum veneer on a wall surface frame body.

The fixing hole 2 may be a pair of circular holes or a single elongated hole.

In the configuration shown in fig. 2, it can be seen that the bolt 11 is mounted to the back of the plate body 6 by means of a patch 12, which belongs to the preferred embodiment, and in some embodiments it is also possible to use a strip-shaped mounting plate or an integral mounting plate for the mounting of the bolt 11 on the plate body 6.

The patch 12 is mounted on the board body 6 by using a metal adhesive, and the metal adhesive is a glue mainly composed of ethyl cyanoacrylate (ECA, also called 2-cyano-2-ethyl acrylate), and can be used for bonding between metals, and the connection strength is comparable to welding.

The current price of the metal adhesive is about 80-100 yuan per kilogram, and the metal adhesive can be used in a large range in industry.

Compared with the effect that welding is easy to generate high-temperature deformation and denaturation on a welded part, the metal adhesive does not generate the problems of deformation and deformation of the connected part, and has irreplaceable effect on connection of ultrathin parts and the like.

In addition, the metal adhesive can be cured within about 5 seconds, so that the metal adhesive does not need to be cooled for next treatment like welding, and the use of the metal adhesive can effectively improve the assembly efficiency.

As for the mounting plate, it can be known from the foregoing that it can be a monolithic plate itself, or a split plate, in the embodiment of the present invention, it is preferable that the split plate is produced in the aluminum veneer production workshop, because the shape of the scrap is irregular, it is more suitable for small applications, the projection 17 shown in fig. 5 is produced by stamping, and the patch 12 can be used after further punching to form the via hole 18.

The protrusion 17 and the via hole 18 may be formed in one step, and a progressive die may be used. Since the patches 12 correspond to the bolts 11 one-to-one in the embodiment of the present invention, the patch blank does not have a high requirement for its shape, although it is shown as a rectangular piece in fig. 2, it is only necessary to substantially satisfy a sufficient mounting area, and it can be in various shapes, so that the aluminum single plate leftover can be almost used to make the patches 12.

When the patch 12 is manufactured, the leftover is firstly leveled by using a mold so as to obtain better mounting conditions.

Similarly, the pellet 23 shown in fig. 8 can also be made of offal, thereby consuming a large amount of offal rather than being disposed of as waste, saving a large amount of cost.

As mentioned above, the strength of the metal-to-metal bond is comparable to that of the solder, so that, for example, the area of the patches 12 for mounting does not need to be too large, and generally, the area of each patch 12 that can be used for mounting is not less than 0.25 square centimeter, which is sufficient, and the patches 12 with relatively regular shapes can more easily achieve that the resultant force of the bond coincides with the axis of the locked bolt 11.

Generally, several uniformly distributed glue dots are formed on the patch 12 by means of glue dispensing, so that the patch 12 can be reliably fixed on the board 6.

In particular, for a relatively large mounting plate, a plurality of connection points can be formed by glue dispensing instead of full-surface gluing.

In some embodiments, if the mounting plate is relatively large, both ends can be in contact with the back-side flange 4, for example, and the connection between the ends of the back-side flange 4 and the mounting plate can be formed by welding, but as much as possible no welding is used.

In the mechanical field, even edge connections can be used, and therefore when the end of the mounting plate comes into contact with the back-side flange 4, a metal-adhesive connection can be used here.

Note that, regarding the amount of use of the bolts 11, it is not preferable to use more than 8 bolts per square meter, taking the area of the back surface of the plate body 6 as a parameter, and therefore, the patches 12 are preferably used to fix the bolts 11 to the back surface of the plate body 6.

In addition, the number of bolts 11 used is not preferably less than 6 per square meter, which is generally a parameter based on the area of the back surface of the plate body 6.

It should be further considered that, regarding the plate body 6, the back surface area is generally less than 1 square meter, and if the plate body 6 is too small, the reinforcing ribs 5 are not actually required for reinforcement, and the plate body 6 reinforced by the reinforcing ribs 5 has the back surface area generally not less than 0.3 square meter.

If the bolts 11 are selected, the number of bolts used per plate body 6 is not less than 2 even if the plate body 6 is small.

The mounting plate can cover the back of the plate body 6 completely or partially, and the latter is preferable, in a more preferable embodiment, the total area of the back of the plate body 6 covered by the mounting plate is not more than one tenth of the total area of the back of the plate body 6, so as to reduce the total weight of the heat-insulating aluminum veneer and reduce the usage amount of good thermal conductors.

In the configuration shown in fig. 2, 10 bolts 11 form a matrix of rows and columns, two for five, one reinforcing bar 5 for each row, and in some embodiments, the reinforcing bars 5 may also be arranged in a longitudinal and transverse manner, not limited to the single transverse arrangement shown in fig. 3.

As shown in fig. 6, the head 12 of the bolt 11 is located on the side of the chip 12, and the shank portion extends in a direction away from the plate body 6 and is perpendicular to the plate body 6.

In fig. 3, the inner insulating layer 14 is omitted for clearly showing the relationship between the reinforcing ribs 5 and the back surface of the plate body 6, and in the preferred embodiment of the present invention, the inner insulating layer 14 is installed first, and then the reinforcing ribs 5 are installed; in other embodiments, the reinforcing ribs 5 can be added first, and then the insulating layer 14 can be installed. For the latter, the reinforcing ribs 5 can be of welded construction, after which the preparation of the lacquer layer on the back-side flange 4 can be carried out. For the former, the back-side flanging 4 is required to be connected with the reinforcing rib 5 and then the anticorrosive paint layer is sprayed or roll-coated without preparing a paint system.

As can be seen from fig. 3, the reinforcing ribs 5 are supported to be separated from the back surface of the plate body 6 by a distance equivalent to the thickness of the inner insulating layer 14, so that the insulating layer is generally compressible, and in order to achieve relatively reliable installation, the reinforcing ribs 5 are fixed by the bolts 11 and then have a certain pre-tightening force, and relatively speaking, the thickness of the inner insulating layer 14 in a loose state is larger than the distance from the back surface of the plate body 6 when the reinforcing ribs 5 are supported.

In contrast, the inner insulation layer 14 is penetrated by the bolts 11, and in some embodiments, after the inner insulation layer 14 is installed, the reinforcing bars 5 are installed, and nuts matched with the bolts 11 are used for fixing the reinforcing bars 5 in place.

Correspondingly, the reinforcing ribs 5 are provided with bolt holes.

Further, the outer insulating layer is laid to a height approximately corresponding to the height of the back-side turned-up edge 4 as shown in fig. 7, and in some embodiments, may be relatively thick and higher than the height of the back-side turned-up edge 4 as shown in fig. 9. Due to the elasticity, the cold bridge effect of the back-side flap 4 is masked or reduced.

The inner and outer insulating layers may be of the same nature and may be adapted for direct connection, and in some embodiments may be bonded directly, for example, asbestos, rock wool, may be in the form of blocks and may be bonded directly to each other.

Asbestos and rock wool both belong to inorganic heat-insulating materials, have high fire-proof rating, can be made into blocks in advance, and are beneficial to constructing an internal and external heat-insulating layer.

When asbestos or rock wool is used as the heat insulating material, a structure as shown in fig. 4 may be adopted, that is, the inner heat insulating layer 14 is prepared, then the reinforcing ribs 5 are installed, and the end portions of the reinforcing ribs 5 may be welded to the back-side flanges 4.

In some embodiments, if the structure shown in fig. 4 is adopted and the fire-proof rating of the thermal insulation material is lower than a2 rating, the connection between the reinforcing rib 5 and the back-side flange 4 can be made by a metal adhesive bonding structure.

In the foregoing embodiments, it is indicated that the mounting plate is preferably in a block structure, and the number of the mounting plate is based on the usage amount of the bolts 11, the blocks are in one-to-one correspondence with the bolts 11 to form the patches 12, and a preferable locking structure is formed between the patches 12 and the bolts 11.

In the configuration shown in fig. 5 and 6, the die 2 is punched by stamping to form the protruding portion 17 and the through hole 18 shown in fig. 5, the through hole 18 is used for the bolt 11 to pass through, and the front surface of the die 12, i.e. the surface attached to the back surface of the plate body 6, is formed with the counter bore 19 for receiving the bolt head 20.

The counter bore 19 has low precision requirement and can be directly punched.

The mold has relatively good structural consistency, and the supporting heights of the plurality of convex parts 17 are approximately consistent, so that the positioning of the reinforcing ribs 5 can be satisfied.

The through hole 18 is preferably a smooth hole, which is advantageous for integral molding, and in some embodiments, the through hole may be processed into a threaded hole, and the bolt 11 may be directly screwed thereto.

If the through hole 18 is a smooth hole, the bolt head 20 requires an initial securing structure, and in some simple applications, the counter bore is filled directly with a gel to establish an initial friction mechanism. It will be appreciated that the structure shown in fig. 6 can be used as an assembly, and is a spare part as a whole, so that the filling gel meets the curing time requirement of the gel, and the industrialization condition is better.

In some embodiments, the adhesion between the bolt head 20 and the unthreaded hole 19 is relatively low, and the spot welding forms a welding spot to meet the required adhesion requirement.

In some embodiments, the rotation stop can be performed by using an elastic washer, and in a better embodiment, a rotation stop gasket is directly adopted.

In the preferred embodiment, the inner insulation layer 14 is further bonded chemically, i.e., adhesively, in addition to being pressed with the reinforcing ribs 5, to improve the overall connection reliability and to prevent falling off. The inner heat-insulating layer 14 and the plate body 6 are not easy to be degummed under the pressing of the reinforcing ribs 5.

The adhesive used for bonding the inner insulating layer 14 to the plate body 6 can be conventional industrial adhesive with low price, namely adhesive in general, preferably acrylic adhesive and epoxy adhesive with lower price.

For the glue used for filling the counter bore 19 and the bolt head 20, a structural glue is used.

After the inner heat-insulating layer 14 is adhered by glue, the part of the inner heat-insulating layer 14 which is not directly pressed by the reinforcing ribs 5 is not easy to turn up, and furthermore, a U-shaped iron wire piece is pre-arranged in the inner heat-insulating layer 14 in the normal direction of the plate body 6 in a penetrating manner, and a connecting length is reserved after two arms of the U-shaped iron wire piece penetrate through the inner heat-insulating layer 14.

As for the iron wire, a zinc-plated iron wire having a wire diameter of not more than 2mm and not less than 0.7mm is preferable.

The connection length needs to be satisfied with the connection of outer heat preservation to after the iron wire pierces through outer heat preservation, the remaining connection length part is enough to fix outer heat preservation.

Accordingly, the connection length portions of the U-shaped wire members 15 are further folded or connected to each other after passing through the outer insulation layer to form a binding portion, thereby fixing the outer insulation layer.

Furthermore, the inner and outer heat-insulating layers can be further bonded by industrial glue.

In the configuration shown in fig. 7, the U-shaped wire 15 is fitted with a pressing piece 23, and in the configuration shown in fig. 8, two arms of the pressing piece 23 located at the U-shaped wire are provided with insertion holes 24.

Accordingly, the pressing pieces 24 pressed against the outer surface of the outer insulation layer are pressed by the connection length portions passing through the back-folding via the corresponding insertion holes 24.

Further, the bolt 11 is exposed from the outer surface of the outer insulating layer;

accordingly, as shown in fig. 7, the outer insulating layer is pressed by the nuts 21 coupled with the spacers 22 and the exposed bolt portions, thereby more reliably pressing the insulating layer.

In the structure shown in fig. 7, a side plate corresponding to the upper edge of the panel 6 in the mounted state, i.e. the upper side plate 10 shown in the figure, is provided, and the upper side plate 10 is folded backwards and forms an angle of 89 degrees with the back surface of the panel. In the mounted state, the upper side plate 10 is pressed against and substantially perpendicular to the plate body 6.

The upper side plate 10 is also provided with an angle code 3, so that the heat-preservation aluminum veneer can be reliably assembled on the decorated object.

Fig. 9 to fig. 11 show the right view structure schematic diagram of three kinds of heat preservation aluminum veneers, and to the application of difference, the heat preservation aluminum veneer can produce multiple structural deformation, and technical personnel in this field can adapt to different application objects, and adopt different structural style, if in the basic idea of the utility model, the simple transformation to the relevant structure should all fall into within the protection scope of the utility model.
