In order to further improve the heat preservation efficiency, a method adopts a form of disconnecting with a main body structure at the root of a balcony, and a heat-insulating bridge structure is added. Wherein a thermal insulation box (also called a thermal insulation connection box) is used for thermal insulation between the building body and the cantilever plate. However, the new form of the bridge also presents problems.
Fig. 1 shows a schematic view of a balcony thermal bridge connection.
As shown in fig. 1, the left half part of fig. 1 is an outdoor balcony main body, the right half part is an indoor, and a thermal insulation box 110 is arranged on the outer wall of the house. In the conventional building connection, the floors of the indoor and balcony are directly connected to become outlets for heat loss, while the novel balcony of fig. 1, the insulation box 110 is disposed at a connection portion of the indoor floor 120 under the indoor floor and the balcony floor 130 under the outdoor balcony floor, and the insulation box 110 may be filled with insulation material, thereby blocking heat transfer between floors. However, due to the discontinuity of the floor slab, the insulation boxes 110 of the heat insulation bridge structure are in direct contact with the concrete structures at two sides, when the waterproof measures of the superstructure fail (not in place, are aged, etc.), the open balcony can directly face the erosion of rainwater, and when the floor drain is not in time and the floor drain is blocked, the balcony ponding can be caused. When the balcony is soaked for a long time, water can more easily infiltrate into the heat insulation layer 140 at the root of the balcony along the slab joint at the joint, so that leakage of going upstairs and downstairs is caused, economic loss is caused for house decoration, and disputes between neighbors and properties are caused.
In order to solve the leakage problem of the heat-break bridge, improvement in the structure of the insulation case 110 is required to improve the leakage problem.
Fig. 2 shows a schematic view of a thermal insulation box in an embodiment of the present application.
As shown in fig. 2, the left half is an outdoor balcony, the right half is an indoor, and when water accumulation or even leakage occurs in rainy days, leaked water flows along a leakage path 210, and when the surface where the leaked water flows is smooth, the water flow easily leaks to the lower floor due to a capillary effect caused by surface tension. The conventional balcony is coated with waterproof glue at the junction of the floor and the threshold for waterproofing, but such paint is easily damaged to cause waterproofing failure. The embodiment of the application provides a waterproof roll 220, and the waterproof roll 220 is made of a sealing material, and besides the waterproof coating layer is arranged on the ground part, the waterproof material is filled in the underground part of the connecting part of the balcony floor and the threshold, and the gap between the balcony floor and the building main body is filled. However, the waterproof material has a problem of aging, so that it is necessary to provide a structure for reducing leakage of water to the surface of the insulation box 110 on the leakage path 210, for example, to provide an inclined edge of the insulation box 110 near the surface of the leakage path 210 to increase the climbing distance of water flow.
Illustratively, the thermal insulation box 110 may be a rectangular parallelepiped structure. The thickness of the insulation box 110 in the first direction X may match the thickness of the insulation layer of the building body, or may be less than the thickness of the insulation layer, which is not limited in this application.
It should be understood that the thermal box 110 may have other structures, and may be adapted according to the structure of the building body or the structure of the floor.
The insulation box 110 may include a rigid structural shell and a filler having an insulating function.
The housing of the rigid structure may be made of a rigid material, such as metal, PVC material, etc.
The thermal insulation material may be rock wool.
The rock wool material is used as a heat insulation material and has excellent fireproof performance, and the rock wool is used as a heat insulation material, so that the heat insulation effect is achieved, and meanwhile, the heat insulation material also has fireproof performance, and the performance of the balcony connecting piece can be improved.
The insulation boxes 110 may be fixed to the floors at both sides through connection ribs, or may be filled only at the connection of the floors in the house and the balcony, which is not limited in this application.
The waterproof structure of the insulation box 110 according to the embodiment of the present application is described below with reference to fig. 3 to 7.
Fig. 3 is a perspective view of a thermal insulation box in an embodiment of the present application.
As shown in fig. 3 as a thermal insulation box 110, the thermal insulation box 110 is used to connect a building body and a balcony and insulate heat between the building body and the balcony. The insulation box has a first surface 310 and a second surface oppositely disposed along a first direction (X), wherein the first surface 310 is a surface connecting the balcony, the second surface is a surface connecting the building body, and the first direction (X) is parallel to the horizontal direction. When leakage occurs, the leaked water permeates in the second direction (Y) parallel to the gravity direction, i.e., needs to pass through the first surface 310 of the insulation box 110, and when the first surface 310 is a smooth plane, the leaked water will be hardly blocked during downward leakage, thereby causing the downstairs roof to get wet and even damaging the building structure. Accordingly, a first protruding eave 320 may be provided at the top end of the first surface 310 of the thermal insulation case 110 in the second direction (Y), and the first protruding eave 320 protrudes obliquely downward from the top end of the first surface 310, and can function to block the leaked water from flowing downward.
As a possible implementation, the normal vector of the plane of the first protruding eave 320 forms an acute angle with the clockwise direction of the X-axis, i.e. the angle formed by the first protruding eave 320 and the first surface 310 is an acute angle, preferably 30 ° -60 °. When the normal vector of the plane of the first protruding eave 320 and the clockwise angle of the X-axis are acute angles, the water leaking from the first protruding eave 320 permeates downwards along the first surface 310, and for example, when the extending length of the first protruding eave 320 is 1cm, the climbing distance of the leaked water in the downward permeation process is increased by at least 1cm by each first protruding eave 320.
As another possible implementation, the bottom end of the first surface 310 in the second direction (Y) is provided with a second protruding eave 330, the second protruding eave 330 protruding obliquely upwards from the bottom end of the first surface 310. The normal vector to the plane of the second projecting eave 330 is at an acute angle to the counterclockwise direction of the X-axis, i.e., the angle formed by the second projecting eave 330 and the first surface 310 is at an acute angle, preferably 30 ° -60 °. When the included angle between the normal vector of the plane where the second protruding eave 330 is located and the counterclockwise direction of the X-axis is an acute angle, the water climbing distance is further increased when the leaked water permeates downwards along the first surface 310, and the second protruding eave 330 and the first surface 310 together form a groove to further prevent the leaked water from permeating downwards.
As yet another possible implementation, a plurality of protruding eaves may also be provided on the first surface 310, thereby enhancing the barrier effect to leaking water.
In the embodiment that this application provided, be provided with first outstanding eaves on the surface that the water of seepage flowed through on the heat preservation box, this first outstanding eaves has certain inclination to increased the climbing distance of water, hindered the process of the water downhill leakage of seepage, thereby brought the water-proof effects for the heat preservation box.
Fig. 4-7 are schematic cross-sectional views of a thermal insulation box provided in an embodiment of the present application.
As shown in fig. 4, the insulation box 110 is provided between a building main body floor (i.e., an indoor floor) and a balcony floor for connection and insulation. When a leak occurs, the water leak path 210 coincides with the direction of gravity. Because of the surface tension of the water, the water leak path 210 tends to be continuously distributed along the first surface 310. Since water is downwardly permeated by gravity, it is considered to increase the climbing distance of water in order to hinder the permeation of water. In combination with the foregoing embodiments, as a possible implementation, a plurality of protruding eaves may be disposed on the first surface 310 to further increase the climbing distance of the leaked water.
Illustratively, first projecting eave 320 forms an angle θ with first surface 310 1 May be 0 ° -90 °, and preferably the included angle may be 30 ° -60 °.
Illustratively, the second projecting edge 330 forms an angle θ with the first surface 310 2 May be 0 ° -90 °, and preferably the included angle may be 30 ° -60 °.
It should be appreciated that when a plurality of protruding eaves are disposed on the first surface 310, the extending directions of the protruding eaves may be different from each other with respect to the first surface 310.
Exemplary, thickness d of the insulation box 1 The thickness of the insulating layer can be matched with that of the building main body, and can be smaller than that of the insulating layer so as to adapt to the structure of a building.
Illustratively, the dimension d of the first projecting eave 320 in the first direction (X) 2 May be the thickness d of the thermal insulation box 110 1 From 0 to 1 times, preferably, dimension d 2 Is one fourth of the thickness of the thermal insulation box.
Exemplary, the insulation box thickness h 1 May be matched to the thickness of the indoor floor 120 and balcony floor 130.
As another possible implementation, when the balcony to which the insulation box 110 is connected leaks, the leaked water leaks to the indoor floor along the top end of the insulation box 110, and then permeates downward along the second surface 410 of the insulation box 110 on the indoor floor side under the action of gravity. In order to prevent the leaked water from penetrating the second surface 410, a third protruding eave 420 may be disposed on the second surface 410, and further, the third protruding eave 420 is disposed obliquely, that is, an angle is formed between an extending direction of the third protruding eave 420 and the second surface 410.
Another embodiment of the thermal insulation box 110 shown in fig. 5 is different from the thermal insulation box 110 in fig. 4 in that a first bending portion 510 is further disposed on the first surface 310 of the thermal insulation box 110 in fig. 5, the first bending portion 510 is disposed between the first protruding eave 320 and the second protruding eave 330, and the first bending portion 510 and the first surface 310 form a first cavity 520 with an upward opening. As the leaked water flows down the first surface 310 along the leak path 210, it accumulates in the first cavity 520, so that the surface tension of the water prevents the leaked water from further climbing before the cavity volume reaches a certain threshold, thereby reducing the leakage of water at the junction and enhancing the water-proof capacity between the upper and lower floors.
As a possible implementation manner, the first bending portion 510 may include a first extension 511, a second extension 512, and a third extension 513, where the first extension 511 is connected to the first surface 310 and extends along the first direction (X), the second extension 512 is connected to the first extension 511 and extends upward along the second direction (Y), and the third extension 513 is connected to the second extension 512 and extends obliquely upward near the first surface (310), and the first extension 511, the second extension 512, and the third extension 513 together form a semi-closed first cavity 520.
Illustratively, the lower end of the eave of the L-shaped cross section formed by the first extension 511 and the second extension 512 may be approximately perpendicular to the first surface 310 or may have a certain angle with respect to the normal line of the first surface 310. For example, the included angle may be 0 ° -90 °.
Exemplary, the third extension 513 forms an angle θ with the second extension 512 3 120-150 deg..
In the embodiment that this application provided, third extension and this second extension form the angle for the obtuse angle, and the water of seepage needs to be soaked to the dihedral angle upwards to the decubitus direction and just can break away from the cavity, has further strengthened the retaining ability, reduces the seepage of water.
Exemplary, the first bending portion 510 has a dimension in the first direction (X) of the thickness d of the thermal insulation box 110 1 From 0 to 5 times, preferably d 1 One third of (3).
Exemplary, the first bending portion 510 has a dimension in the second direction (Y) of the height h of the thermal insulation box 110 1 Preferably, the length is d 1 One third of (3).
As yet another possible implementation, the first extension 511, the second extension 512, and the third extension may also be eaves with arc-shaped cross sections, where a groove structure similar to a half cylinder, i.e., the first cavity 520, may be formed between the first extension 511, the second extension 512, and the third extension 513 and the first surface 310.
As yet another possible implementation, the first bending portion 510 may be an eave having an arc-shaped cross-section with an angle of less than 180 ° so as not to contact the first surface 310, and form a first cavity 520 with the first surface 310.
The above embodiments are merely exemplary, and one skilled in the art can reasonably configure the structure of the first bending portion 510 to form a semi-closed first cavity 520 with the first surface 310 according to the need.
As another example, when leakage occurs in the balcony to which the insulation box 110 is connected, the leaked water leaks to the indoor floor along the top end of the insulation box 110, and then permeates downward along the second surface 410 of the insulation box 110 on the indoor floor side by gravity. In order to hinder the penetration of leaked water at the second surface 410, a waterproof structure may be provided on the second surface 410, and the waterproof structure may refer to the above-described embodiments.
As an example, the top end of the second surface 410 in the second direction (Y) is provided with a third protruding eave 420, and the third protruding eave 420 protrudes obliquely downward from the top end of the second surface 410; a fourth protruding eave 430 is provided at the bottom end of the second surface 410 in the second direction (Y), and the fourth protruding eave 430 protrudes obliquely upward from the bottom end of the second surface 410.
As shown in fig. 6, a thermal insulation box 110 according to still another embodiment is different from the thermal insulation box 110 in fig. 4 in that a first protrusion 340 is further provided on a first surface 310 of the thermal insulation box 110, and the first protrusion 340 protrudes in a horizontal direction. The first tab 340, the first projecting eave 320, and the first surface 310 form a semi-enclosed second cavity 610. The opening of the second cavity 610 may be of a relatively small size such that the surface tension of the water may allow the leaked water to infiltrate the second cavity 610, for example, 2mm-5cm, preferably, 2mm-2cm, and more preferably, 2mm-1cm, such that the water falling into the second cavity 610 is accumulated in the second cavity 610 due to the surface tension.
In the embodiment provided herein, since the second cavity 610 semi-closed by the first protrusion 340, the first protrusion eave 320 and the first surface 310 is formed on the first surface 310, the leaked water may flow into the second cavity 610 along the slit of the second cavity 610 opening and accumulate in the second cavity 610 due to the surface tension of the water, thereby more stably blocking the downward leakage of the water.
As one possible implementation, there may be a plurality of second cavities 610 on the first surface 310, for example, 2 first protrusions 340 and first protruding eaves 320 may constitute 2 second cavities 610, which is merely an example of an illustrative nature, and one skilled in the art may arrange a reasonable number of second cavities 610 as needed.
A further embodiment of the present application provides a thermal break junction box 110 as shown in fig. 7. Which may be combined with the various waterproof structures of the above-described embodiments as a further waterproof means. A waterproof structure can also be added on the second surface.
As a possible implementation, the height of the thermal insulation junction box 110 may be adapted to the thickness of the indoor floor 120 and balcony floor 130.
As another possible implementation, when the balcony to which the insulation box 110 is connected leaks, the leaked water leaks to the indoor floor 120 along the top end of the insulation box 110, and then permeates downward along the second surface 410 of the insulation box 110 on the indoor floor side under the action of gravity. In order to prevent the leaked water from penetrating through the second surface 410, a second bending portion 710 may be disposed on the second surface 410, where the second bending portion 710 is disposed between the third protruding eave 420 and the fourth protruding eave 430, and the second bending portion 710 and the first surface 310 form a third cavity 720 with an upward opening.
As a possible implementation manner, the second bending portion 710 may include a fourth extension 711, a fifth extension 712, and a sixth extension 713, where the fourth extension 711 is connected to the second surface 410 and extends in a direction opposite to the first direction (X), the fifth extension 712 is connected to the fourth extension 711 and extends upward in the second direction (Y), and the sixth extension 713 is connected to the fifth extension 712 and extends obliquely upward near the second surface 410, and the fourth extension 711, the fifth extension 712, and the sixth extension 713 together form a semi-enclosed third cavity 720.
As another possible implementation, the second surface 410 may be further provided with a second protrusion 730, the second protrusion 730 protruding in a horizontal direction, and the second protrusion 730, the third protrusion eave 420, and the second surface 410 form a semi-closed fourth cavity 740.
The embodiment of the application also provides a balcony, which comprises the heat-insulating connecting box. The balcony may further comprise: the waterproof bead 220 in the embodiments of the present application described above.
It should be understood that the technical features of the different embodiments described in the present application may be combined with each other as long as they do not conflict with each other.
While the invention has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the invention. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
