Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a UHPC ultra-thin exterior wall insulation layer. Background Art

[0002] Currently, the prefabricated components of prefabricated insulated exterior wall panels are all made of ordinary concrete, with a minimum thickness of no less than 60 mm. This results in thicker and heavier components. Furthermore, the excess thickness of the components results in an excessively thick exterior wall after installation, impacting the building area of the individual units. If concrete were used, production, hoisting, and joint connection would be more complex and challenging.

[0003] At present, the prefabricated insulated exterior wall panels of engineering projects are all prefabricated components composed of prefabricated concrete panels and integrated insulation panels. After being processed in the component factory, they are transported to the site for hoisting. At this stage, the prefabricated parts of prefabricated insulated exterior wall panels are all made of concrete, with a minimum thickness of not less than 55. The overall thickness of the single-component integrated insulation panel is relatively thick (over 95) and heavy.

[0004] When the weight of a single component of the prefabricated part on the exterior wall surface of the connection part is large, it will have a significant adverse effect on the deformation of the entire exterior wall surface after the overall installation is completed. Utility Model Content

[0005] The present invention aims to solve the problem that conventional prefabricated thermal insulation exterior wall panels made of ordinary concrete are too thick and heavy, which easily causes deformation of the exterior wall of a building. The technical solution adopted is: a UHPC ultra-thin exterior wall insulation layer, comprising: a plurality of prefabricated thermal insulation exterior wall panels arranged in an array on the exterior wall of the building, with a buffer provided between two adjacent prefabricated thermal insulation exterior wall panels, a draw die connector array provided on the back of each prefabricated thermal insulation exterior wall panel, and adjacent prefabricated thermal insulation exterior wall panels connected by a plurality of connecting pieces, each of which is connected to the connecting connectors of two adjacent prefabricated thermal insulation exterior wall panels;

[0006] The insulated prefabricated exterior wall panel includes: an exterior wall panel body, the outer surface of the exterior wall panel body is covered with a first insulation layer, and the exterior wall panel body is prefabricated from ultra-high performance concrete; a second insulation layer is provided on the surface of the exterior wall panel body around the first insulation layer, and the outer edge of the second insulation layer is flush with the edge of the exterior wall panel body.

[0007] A further improvement is that the edges of the thermal insulation prefabricated exterior wall panels are provided with tongues and grooves, and the buffer member is provided between the tongues and grooves of two adjacent thermal insulation prefabricated exterior wall panels.

[0008] A further improvement is that there are two buffer members, and the two buffer members are respectively arranged on the inner side and the outer side of the tongue and groove.

[0009] A further improvement is that a glue layer is coated on the gap between two adjacent thermal insulation prefabricated exterior wall panels and on the outer side of the outer buffer member.

[0010] A further improvement is that the second thermal insulation layer is a silicon graphene thermal insulation layer.

[0011] A further improvement is that the exterior wall panel body is provided with flanges facing the outer surface on all sides, and the height of the flanges is lower than the height of the outer surface of the first insulation layer, and the second insulation layer is covered on the flanges.

[0012] A further improvement is that the outer surface of the second thermal insulation layer is flush with the outer surface of the first thermal insulation layer.

[0013] A further improvement is that the four corners of the exterior wall panel body are provided with flanges, and the height of the flanges is consistent with the height of the outer surface of the second insulation layer.

[0014] The beneficial effects of the utility model are:

[0015] The UHPC ultra-thin exterior wall insulation layer provided by the present invention is prefabricated with UHPC thermal insulation prefabricated exterior wall panels, thereby greatly reducing the thickness of the prefabricated layer, thereby reducing the overall thickness of the building's exterior wall and greatly reducing the overall weight; at the same time, each prefabricated thermal insulation exterior wall panel has a connector array on the back, which disperses the gravity of the prefabricated thermal insulation exterior wall panel to each connector, and adjacent prefabricated thermal insulation exterior wall panels are connected into a whole by connecting pieces, so that the gravity of the entire insulation layer is evenly distributed to the connectors of each prefabricated thermal insulation exterior wall panel, thereby avoiding deformation of the building's exterior wall caused by the heavier prefabricated thermal insulation exterior wall.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of a utility model, "plurality" means two or more, unless otherwise specifically defined.

[0025] In utility models, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in utility models based on specific circumstances.

[0026] like Figure 1-2 As shown, the present invention also provides a UHPC ultra-thin exterior wall insulation layer, including a plurality of prefabricated exterior wall panels arranged in an array on the exterior wall 100 of a building, the prefabricated exterior wall panels are connected to the exterior wall of the building through corresponding embedded connectors, and a buffer member 5 is provided between two adjacent prefabricated exterior wall panels to prevent adjacent prefabricated exterior wall panels from colliding and causing damage, thereby reducing the overall insulation performance. Wherein, the buffer member 5 is preferably a PE rod. A plurality of die connectors 8 are provided on the back of each prefabricated exterior wall panel, and the plurality of die connectors form a die connector array. Each prefabricated exterior wall panel is connected to the exterior wall 100 of the building through the die connector array, and the weight of the prefabricated exterior wall panel is dispersed through the plurality of die connectors 8. As shown Figure 3As shown, in order to make the thermal insulation prefabricated exterior wall panels on the exterior wall 100 of the building form a whole, two adjacent thermal insulation prefabricated exterior wall panels are connected by multiple connecting pieces 9, and the connecting piece 9 is arranged on the back of the thermal insulation prefabricated exterior wall panel. The same connecting piece 9 is respectively connected to the connecting connectors 10 of the two adjacent thermal insulation prefabricated exterior wall panels. The connecting connector 10 is arranged at the edge of the thermal insulation prefabricated exterior wall panel, and at least two connecting connectors 10 are provided on each side, and each connecting connector 10 is connected to a connecting piece 9.

[0027] like Figure 2 As shown, in order to prevent rainwater and the like from penetrating between the thermal insulation prefabricated exterior wall panels and the exterior wall of the building, a further improvement of the present technical solution is that a tongue and groove 6 is provided at the edge of the thermal insulation prefabricated exterior wall panels, and a buffer member 5 is provided between the tongue and groove 6 of two adjacent thermal insulation prefabricated exterior wall panels.

[0028] like Figure 4 and Figure 5 As shown, the thermal insulation prefabricated exterior wall panel includes: an exterior wall panel body 1, which is prefabricated, and the outer surface of the exterior wall panel body 1 is integrated with a first thermal insulation layer 2 to form an integral panel with the exterior wall panel body 1, and the exterior wall panel body 1 is prefabricated from ultra-high performance concrete (UHPC). It is cast in one step using ultra-high performance concrete (UHPC). Without reducing the overall performance, its thickness is greatly reduced compared to the thermal insulation exterior wall panel cast with ordinary concrete.

[0029] The cold bridge effect can lead to heat conduction indoors, resulting in energy waste. To address this issue, a further improvement to this technical solution is that a second insulation layer 3 is adhered to the surface of the exterior wall panel body 1 surrounding the first insulation layer 2, with the outer edge of the second insulation layer 3 flush with the edge of the exterior wall panel body 1. Since the entire outer surface of the exterior wall panel body 1 is covered by the insulation layer, the formation of cold bridges is avoided, the indoor temperature is locked in, and energy waste is avoided.

[0030] The UHPC ultra-thin exterior wall insulation layer provided by the present invention is prefabricated with UHPC thermal insulation prefabricated exterior wall panels, thereby greatly reducing the thickness of the prefabricated layer, thereby reducing the overall thickness of the building's exterior wall and greatly reducing the overall weight; at the same time, each prefabricated thermal insulation exterior wall panel has a connector array on the back, which disperses the gravity of the prefabricated thermal insulation exterior wall panel to each connector, and adjacent prefabricated thermal insulation exterior wall panels are connected into a whole by connecting pieces, so that the gravity of the entire insulation layer is evenly distributed to the connectors of each prefabricated thermal insulation exterior wall panel, thereby avoiding deformation of the building's exterior wall caused by the heavier prefabricated thermal insulation exterior wall.

[0031] A further improvement is that there are two buffer members 5, and the two buffer members 5 are respectively arranged on the inner and outer sides of the tongue and groove 6, which not only effectively avoids the tongue and groove of the thermal insulation prefabricated exterior wall panel from being damaged due to collision, but also the inner and outer layers can effectively prevent the infiltration of rainwater.

[0032] In order to further prevent the infiltration of rainwater, a further improvement of the technical solution is that a glue layer 7 is coated on the gap between two adjacent thermal insulation prefabricated exterior wall panels and on the outer side of the outer buffer member 5.

[0033] A further improvement is that the second thermal insulation layer 3 is a silicon graphene thermal insulation layer, which has better thermal insulation performance and flame retardant properties.

[0034] In order to improve the overall structural strength of the exterior wall panel body 1 and prevent it from being damaged due to collision during transportation or construction, the present technical solution is further improved as follows: the exterior wall panel body 1 is provided with a flange 4 facing the outer surface around it, but the height of the flange is lower than that of the conventional flange. The height of the flange 4 is lower than the height of the outer surface of the first insulation layer 2, and the second insulation layer 3 is pasted on the flange 4.

[0035] A further improvement is that the outer surface of the second thermal insulation layer 3 is flush with the outer surface of the first thermal insulation layer 2, so that the whole is more regular and beautiful.

[0036] In order to protect the first insulation layer and the second insulation layer and prevent them from being damaged due to scratches during transportation and construction, the present technical solution is further improved in that the four corners of the exterior wall panel body 1 are provided with flanges 4, and the height of the flanges 4 is consistent with the height of the outer surface of the second insulation layer 3, so that when stacking, the insulation layer is prevented from being damaged due to the supporting effect of the flanges.

[0037] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
