Description

Heat insulation board

Technical Field

The utility model relates to a heat-insulating board.

Background

Because the narrow building energy consumption accounts for more than eight of the world energy consumption, and the heating and air conditioning energy consumption accounts for two thirds of the building energy consumption, the heat exchange between the indoor and the outdoor through the wall heat preservation is the main means for reducing the building energy consumption. The external wall heat preservation and the internal wall heat preservation are main modes of wall heat preservation, and the current main mode of wall heat preservation is external wall heat preservation because an internal wall heat preservation system occupies a large indoor space.

The heat insulation layer is manufactured in a mounted external wall template mold cavity in the early stage of external wall heat insulation mainly by adopting a polyurethane foaming mode, the mode is not flexible enough in use and poor in heat insulation performance, and due to the fact that the heat insulation layer has continuity and poor fireproof performance, the prefabricated heat insulation plate (called the heat insulation plate for short) completely replaces a field foaming mode to manufacture the heat insulation layer along with the development of the technology.

In order to improve the fireproof capacity, the area (measured by a mounting plate surface) of a single insulation board is not more than 0.6 square meter, and mortar slurry with the thickness not less than 10mm needs to be filled between adjacent insulation boards so as to block a combustion chain. Even so, still need to have higher requirement to the burning grade of heated board itself, and the major component of heated board is generally organic matter, and its major component is organic matter, and fire-retardant rating is generally B level, though the fire-retardant rating of fireproof material has been revised at present, and some B1 level fireproof material is revised to A2 level, does not show that its fire-retardant ability has obtained the promotion. In view of this, in order to further improve the fire-proof capability, a slab joint may be formed on the heat-insulating slab, and the slab joint is filled with mortar slurry with a relatively high fire-proof rating.

Typically, for example, chinese patent document CN102251598A discloses an isolated fireproof insulation board, in which longitudinal and transverse grooves are formed on upper and lower surfaces of an insulation board body made of a B-class material, the grooves on the two surfaces are arranged in a staggered manner, and the grooves are filled with an a-class material. The density of the grooves is high, the damage to the integral strength of the heat insulation plate body is relatively large, and storage and transportation are affected. Furthermore, longitudinal or transverse grooves are relatively easy to groove, but do not take into account the nature of the flame propagation. It is known that the flame has a weak spreading ability towards both sides and a strong spreading ability upwards, and the value of arranging more longitudinal grooves is not great.

Therefore, for example, chinese patent document CN207469491U discloses a composite external template, in which the grooves formed on the thermal insulation board are mainly horizontal plate seams, the vertical plate grooves are auxiliary, and the isolation capability of the horizontal plate seams is stronger than that of the vertical plate seams, so as to reduce the processing amount, reduce the filled materials with weak thermal insulation capability, and reduce the influence on the thermal insulation performance of the thermal insulation board. However, the inventor believes that the longitudinal plate seams are actually in a state opposite to the ribs, have limited capacity of blocking the free radicals of the chain reaction, but can also play a certain role in isolation, and have little value in completely leaving and retaining.

Detailed Description

In general, since the insulation board belongs to an internal member of an external wall insulation system, the insulation board has no special requirement on the decoration requirement, and only the functional requirement is considered in principle, so that the insulation board does not need to consider the surface as an external surface and is a rectangular board as a whole.

It is understood that for the insulation board, whether it is priced or mounted, the area of the mounting surface is calculated, for example, how many sides of the insulation board are needed for a certain building, where the sides are square meters, and the area of the mounting surface, i.e., the inner surface, is calculated. Therefore, the insulation board has the property of a board, and has a first surface and a second surface opposite to the first surface, and the area of the first surface or the second surface is referred to as the area. The remaining surfaces of the insulation board are usually not described in terms of surfaces, but in terms of edges, or lateral edges.

The slab joint that opens on the heated board at present, specifically the groove packs fire prevention heat preservation thick liquids in the slab joint to improve the whole fire behavior of heated board. The fireproof heat-insulating slurry filled in the plate seam can be found in various local standards and group standards, such as the standard numbers DB37/T5071-2016, L09J130 (U2009) and the like, and is not described in detail herein.

In the embodiment of the present invention, the first surface and the second surface are not limited to which surface is a mounting surface, i.e., a surface that is attached to the base wall, or an inner surface. However, in the embodiment of the present invention, the tip of the V-shaped plate seam is defined, or the plate side corresponding to the intersecting position of the two inclined plate seams forming the V-shaped plate seam is the lower side of the insulation plate.

Specifically, referring to the attached drawings 1-4 of the specification, the plate body 1 of the insulation board shown in the drawings is a regular rectangular plate, the current common specifications are 600 gamma 600 (mm) and 900 gamma 600 (mm), the plate thickness is generally 20-70 mm, the upper and lower planeness on the same building often differs by dozens of mm, and finally the outer wall insulation system is used for leveling, the insulation board is mainly leveled by the insulation board, and plates with various plate thicknesses are often required to be prepared for each building.

In contrast, the thicker the insulation board, the better the insulation effect, but the poorer the fire resistance, the better the insulation board is generally made of organic matter with better flammability, although a proper amount of flame retardant can be mixed, the burning grade is generally A2 or below, which is difficult to be improved to A1 grade, and the burning grade of the early insulation board is generally B grade and is mostly B2 grade.

The insulation board is not suitable for being too small, so that the difficulty of on-site mounting can be improved, and the heat conduction capability of the separation seams between the insulation boards is more than four times of that of the insulation board although the separation seams are filled with insulation slurry, so that the board opening seams on the insulation board is a better choice at present. The plate seams are usually not open, forming substantial slots, and the portions that are not open form broken bridges to avoid cold bridges.

The cells constructed on the thermal insulation board by the board seams are generally rectangular cells at present, namely relatively small thermal insulation cells are constructed by the longitudinal and transverse board seams. The heated board itself is the rectangular plate, and when the fluting on the production line, the heated board location is simple relatively, and this has also restricted the use of other types of plate seam.

For the convenience of distinguishing, one surface of the plate body is defined as a first surface, the other surface is defined as a second surface, the two surfaces can be used as mounting surfaces, and correspondingly, the two surfaces are opposite to each other in position on the heat preservation plate.

As can be seen in fig. 1, the plate body 1 has a first side first inclined plate seam 2 and a first side second inclined plate seam 3 on a first side, and the first side first inclined plate seam 2 and the first side second inclined plate seam 2 intersect at the middle of the bottom of the insulation board to form a V-shaped plate seam, and the first side first inclined plate seam 2 and the first side second inclined plate seam 2 may also intersect at the middle to form an X-shaped plate seam, preferably, i.e., preferably, a V-shaped plate seam.

Similarly, referring to the attached figure 2 in the specification, the plate body 1 is provided with a second-surface first inclined plate seam 5 and a second-surface second inclined plate seam 4 on the second surface, and the second-surface first inclined plate seam 5 and the second-surface second inclined plate seam 4 intersect at the middle of the bottom of the heat preservation plate to form a V-shaped plate seam, and also can intersect at the middle to form an X-shaped plate seam.

Accordingly, the intersection point of the X-shaped plate slits is located at the middle of the plate body 1 in the up-down, left-right directions, or at or near the center of the rectangular plate surface of the plate body 1, i.e., in the middle, including but not limited to the middle.

Correspondingly, first face first swash plate seam 2, the first swash plate seam of second face 5 to the one side slope of heated board left and right sides, first face second swash plate seam 3, the second swash plate seam 4 to the opposite side slope of heated board, according to the structure, can separate into triangle-shaped or wedge unit with plate body 1. The inclined plate seam not only has a transverse flame-retardant effect, but also has a certain longitudinal flame-retardant effect. As shown in fig. 2, it is obvious that, in the mounted state, the slurry filled in the first inclined plate seam 5 and the second inclined plate seam 4 of the second surface and the slurry filled between the plates are connected into a whole to form a continuous isolation belt, which can effectively prevent the lower ignition point from spreading upwards to the triangular unit in the middle. The triangular units positioned at two sides can inhibit the smoothness of an ascending channel due to gradual narrowing, so that the further expansion of the ignition chain reaction free radicals can be effectively inhibited.

Although the inclined plate seam can not be directly blocked in the longitudinal direction like a transverse plate seam, compared with the transverse plate seam and a longitudinal plate seam, the inclined plate seam has the advantages of the transverse plate seam and the longitudinal plate seam, and compared with the longitudinal plate seam, the fireproof isolation capability is greatly improved.

Regarding the preparation of swash plate seam, during the batchization preparation, only need the special frock of adaptation can, for example install the rectangle constant head tank on the production line, the rectangle constant head tank is put for the traffic direction of production line is inclined, can be in the direction of following the production line or perpendicular to production line enterprising a knife.

When the groove is milled on a fixed production line, the tool can be fixed on the workbench, and the positioning is also convenient.

Referring to the attached drawings 1-4 in the specification, as can be seen from the drawings, a first inclined plate seam 2 on the first surface and a first inclined plate seam 5 on the second surface extend upwards to a top corner on the upper side of the insulation board; correspondingly, the first surface second inclined plate seam 3 and the second surface second inclined plate seam 4 extend upwards to the other top corner of the upper side of the heat insulation plate, so that three regular triangular units can be constructed.

It should be noted that, as shown in fig. 1 to 4, the regular triangular units are not necessarily selected, and for the inclined plate seams, the groove milling can be performed purely depending on the experience of workers, and does not need to depend on a tool, under the condition, the inclination degree of the inclined plate seams on different insulation boards may be different, but the influence on the overall performance is not great.

Correspondingly, the first face first inclined plate seam 2 and the first face second inclined plate seam 3 intersect at the middle of the bottom of the heat preservation plate to form a first face V-shaped plate seam. The second-surface first inclined plate seam 5 and the second-surface second inclined plate seam 4 intersect at the middle of the bottom of the heat preservation plate to form a second-surface V-shaped plate seam.

As can be seen from fig. 1 and 3, two second-side V-shaped plate seams are provided, and one first-side V-shaped plate seam is provided; correspondingly, two second-face first inclined plate seams 5 are respectively arranged on two sides of the first-face first inclined plate seam 2; two second-face second inclined plate seams 4 are respectively arranged on two sides of the first-face second inclined plate seam 3. This kind of structure, under the condition that does not adopt the full joint, use three swash plate seam to construct labyrinth structure, under the whole not impaired condition of assurance heated board, form good median.

Furthermore, the sum of the depth of the V-shaped plate seam of the first surface and the depth of the V-shaped plate seam of the second surface is more than or equal to the thickness of the heat preservation plate and less than or equal to 1.5 times of the thickness of the heat preservation plate. In general, even if another layer is loaded on the insulation board, the thickness of the insulation board is usually measured by a body having a pure insulation function, and actually the thickness of the board body 1 shown in fig. 1, but in most cases, the insulation board is conventionally called an insulation board, and the insulation board is not usually distinguished by using the board body 1.

Generally speaking, the depth of the first surface V-shaped plate seam and the depth of the second surface V-shaped plate seam are approximately equal to the thickness of the plate body 1, the labyrinth seal is characterized in that the flow resistance is increased through the elbow effect, the V-shaped plate seams are arranged on two surfaces at intervals, and the fireproof isolation belt formed after slurry is filled forms a plurality of elbows so as to retard the propagation of flame.

In a preferred embodiment, the sum of the depths of the first face V-shaped plate seam and the second face V-shaped plate seam is 1.2 times the thickness of the plate body 1.

Further, the first side first inclined plate seam 2 is parallel to the second side first inclined plate seam 5, and the first side second inclined plate seam 3 is parallel to the second side second inclined plate seam 4; in the panel surface of the heat preservation panel, in the direction perpendicular to the first inclined plate seam 2 of the first surface, the distance between the first inclined plate seam 2 of the first surface and the first inclined plate seam 4 of the second surface is 50-70 mm. It should be known that, the closer the plate seam is opened, the stronger the strength of the plate body 1 is weakened, and the heat preservation effect is seriously weakened in local parts, and the proper distance between the plate seams can reduce the influence of stress concentration and has relatively good isolation effect.

It should be noted that as previously mentioned, the accuracy requirements are not high for the fabrication of the swash plate seam, and the parallelism mentioned above is a design dimension rather than a manufacturing dimension.

In a more preferred embodiment, the transverse plate seams and the inclined plate seams are cooperated, so that the isolation effect of the transverse plate seams is fully exerted, and the fireproof capacity of the heat insulation plate is improved on the whole. Correspondingly, transverse plate seams are formed in the longitudinal middle of the insulation plate, which can be seen in particular in fig. 3 and 4.

Further, referring to fig. 3 and 4 of the specification, the transverse plates are sewn into a group structure to form transverse plate seam groups, and the transverse plate seam groups are in one group;

the set of transverse panel slots includes a first panel slot 6 opening on the first side and a second panel slot 7 opening on the second side.

Further, the first and second horizontal plate slits 6 and 7 are sequentially arranged at a longitudinal interval of the insulation plate to construct a labyrinth structure, thereby improving the overall blocking capability.

Comparing fig. 3 and 4, it can be seen that one first-side transverse plate seam 6 and two second-side transverse plate seams 7 reduce the overall number of transverse plate seams under the condition of ensuring the isolation effect, thereby reducing the weakening of the strength and the heat insulation capability of the plate body.

The plate seams are required to be manufactured in a factory, the overall strength of the plate body 1 is inevitably reduced, and the insulation plate is likely to be broken in the storage and transportation process, so that interface mortar is pre-coated on the surface of the insulation plate to form a mortar layer 9. For clarity, in the structures shown in fig. 5 and 6, the mortar is only schematically shown on one side, in a specific application, the mortar layer 9 needs to wholly coat the plate body 1, so as to form a relatively tight coating structure, the mortar in the coating structure is filled into the board joints to form the joint filling bodies 10, the joint filling bodies 10 are formed in a factory stage, but the field forming is not excluded, especially, the mortar can be firstly coated on the mounting surface of the insulation board on the field to adhere the insulation board on the wall, and the mortar is inserted into the board joints to form the joint filling bodies 10 in the process of coating the mortar.

If on the spot, mortar layer 9 can only remain two-layerly, be located mortar layer 9 on first face and the second face, and other sides can not have mortar layer 9, nevertheless because of need keep a certain distance between the heated board, form the parting joint, also can inlay full mortar in the parting joint to keep apart the heated board.

As can be seen from the above, the plate seams on the two surfaces have a depth sum of two pairs greater than or equal to the thickness of the plate body 1, through holes 8 appear at the positions where the second-surface transverse plate seam 7 and the inclined plate seam are staggered as shown in fig. 4, and the through holes 8 are fully embedded when the mortar layers 9 are manufactured, so that the connection between the mortar layers 9 on the two surfaces is formed, which is helpful for improving the overall strength.

The negative effect that thru hole 8 exists is that the heat preservation effect of heated board has declined to some extent, but thru hole 8 area is very little, and especially the thermal conductivity coefficient of present heat preservation mortar can accomplish generally that the heated board keeps warm about four times of ability, and less thru hole 8 is less to the holistic heat preservation effect influence of heated board.

In order to improve the strength of the mortar layer 9 and to improve the crack resistance of the mortar layer 9, a fiber mesh is embedded in the mortar layer 9 at least on the second side of the insulation board. The fiber net is preferably consumable mesh cloth 11, and the mesh cloth 11 is preferably alkali-resistant glass fiber mesh cloth.

For the applicable objects of the heat insulation plate structure, the currently available prefabricated heat insulation plates can be basically used, and common heat insulation plates of the type are GPES heat insulation plates, GPIR heat insulation plates, nano graphite modified plastic heat insulation plates, polystyrene foam plates, graphite extruded plates, polyurethane plates, phenolic aldehyde plates or rock wool composite plates.
