Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and particularly relates to a circumferential combined filling heat preservation strip for reserving openings in an external heat preservation wall body. Background Art

[0002] An old residential area refers to a residential community built before 2000 in a city or county (county seat, town), where public facilities are backward and affect the basic life of residents. At present, the relevant maintenance work of old residential area renovation is being carried out in an orderly manner. Among them, the external wall heat preservation of old residential areas is a crucial renovation project. Building external heat preservation refers to setting a heat preservation layer on the surface of the building external wall to improve the heat preservation performance of the building. Common heat preservation materials include graphite polystyrene board, rock wool board, heat preservation particles, etc., among which graphite polystyrene board is the most widely used. The main function of the building external heat preservation layer is to enhance the heat insulation effect between the wall and the outside, thereby improving the indoor temperature environment. In winter, the heat preservation layer can reduce the loss of indoor heat and keep the indoor temperature; in summer, it can prevent outdoor heat from entering the room and reduce air conditioning energy consumption. This has a significant energy-saving effect for old residential areas, especially in areas with cold winters and hot summers. For old residential areas without heat preservation renovation, a large amount of heating is required in winter to keep the indoor temperature, and in summer, the air conditioner needs to run for a long time to cool down. This not only increases energy consumption but also causes energy waste. After the building external heat preservation renovation, it can effectively reduce energy demand, reduce the operation time of heating and air conditioning, and thus achieve the purpose of energy conservation and emission reduction. The building structures of old residential areas often show varying degrees of damage due to their long history. The external wall heat preservation layer can not only improve the heat preservation performance of the building but also play a certain protective role for the wall. The heat preservation layer can block the erosion of natural factors such as rain, snow, and wind, and extend the service life of the building. In addition, the installation of the heat preservation layer can also enhance the overall strength of the wall and improve the seismic performance of the building.

[0003] During the construction process of building external heat preservation, since relevant outdoor waterproof distribution boxes for indoor work and life have been configured on the original wall body, most of these lines need to be retained in their original positions. However, due to subsequent maintenance and repair, reserved openings need to be formed on the later-constructed building external heat preservation layer. These reserved openings require not only bypassing outdoor waterproof distribution boxes or other electrical control accessories when laying the heat preservation layer but also reserving enough operation space for outdoor waterproof distribution boxes or other electrical control accessories. The generation of these reserved spaces directly affects the overall integrity of the external heat preservation layer itself. Due to the lack of a unified and durable edge sealing method at the edges generated by the reserved positions, the overall heat preservation performance of the external heat preservation layer is affected. Since the widths of the reserved spaces vary due to the need to cooperate with outdoor waterproof distribution boxes or other electrical control accessories of different sizes, and the current treatment measure is only to apply a layer of external plastering at the edges, the gap sealing and heat preservation treatment are not standardized and unified, and there is a lack of heat preservation measures at the reserved spaces. The problems mainly reflected are as follows:

[0004] 1. Fill the gap reserved between the periphery of the electrical box and the external thermal insulation layer with thermal insulation materials. However, the thermal insulation materials are prone to cracking with the wall, resulting in subsequent peeling, loss of the filled thermal insulation performance, and further affecting the thermal insulation performance of the overall thermal insulation layer.

[0005] 2. The reserved gap between the periphery of the electrical box and the wall is filled with cement or caulking paste. Cracking and falling will occur between the cement or caulking paste and the wall, making the subsequent arrangement of the thermal insulation board unstable, reducing the thermal insulation performance of the thermal insulation board, and failing to achieve the purpose of stable and durable thermal insulation.

[0033] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be described below through specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary and do not limit the scope of the present utility model. The structures, proportions, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the implementation conditions of the present utility model. Therefore, they do not have technical substance significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the efficacy that the present utility model can produce and the purpose that can be achieved, should still fall within the scope covered by the technical content disclosed in the present utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present utility model.

[0034] Here, it should also be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, while other details less related to the present utility model are omitted.

[0035] Such as Figures 1 to 7As shown in the figure, the following technical solutions are adopted in this specific implementation manner: The circumferential combined filling thermal insulation strip for the reserved opening of the external thermal insulation wall is a gap filling structure with reasonable and simple operation mode, and is used for filling the matching width position between the edge of the reserved opening on the building external thermal insulation layer being laid or the laid building external thermal insulation layer and the outer edge of the outdoor waterproof distribution box. It includes a combined thermal insulation frame body, which is arranged in the gap between the electrical box 5 and the wall. The building external thermal insulation layer and its construction process are the building external thermal insulation layer made of existing polystyrene boards or other existing building thermal insulation materials, and the corresponding laying construction technology is the laying construction technology of the existing thermal insulation layer. Several combined thermal insulation frame bodies are connected. As Figure 2 shown, the combined thermal insulation frame body includes a transverse thermal insulation strip 1, a longitudinal thermal insulation strip 2, a right-angle fixing frame 3, and self-tapping bolts 4. Concave fixing grooves 11 are provided on the inner side walls of both the transverse thermal insulation strip 1 and the longitudinal thermal insulation strip 2. The right-angle fixing frame 3 is arranged in the fixing groove 11, and the right-angle fixing frame 3 is connected to the transverse thermal insulation strip 1 and the longitudinal thermal insulation strip 2 respectively through self-tapping bolts 4. When in use, first cut the transverse thermal insulation strip 1 according to the length of the gap, then bond the transverse thermal insulation strip 1 to the wall of the gap and fix it with bolts. Then cut the longitudinal thermal insulation strip 2 according to the distance between the two transverse thermal insulation strips 1, bond the longitudinal thermal insulation strip 2 to the wall of the gap and fix it with threads. Then place the right-angle fixing frame 3 in the fixing grooves 11 of the transverse thermal insulation strip 1 and the longitudinal thermal insulation strip 2, and use self-tapping bolts 4 to fix the right-angle thermal insulation frame 3. When the depth of the gap is too large, bond the transverse thermal insulation strip 1 and the longitudinal thermal insulation strip 2 again on the outside of the transverse thermal insulation strip 1 and the longitudinal thermal insulation strip 2 to fill the gap. As Figure 3 shown, anti-slip grooves 12 are provided at the inner bottom of the fixing grooves 11 of the transverse thermal insulation strip 1 and the longitudinal thermal insulation strip 2. As Figure 4 shown, several anti-slip sawtooth bodies 3-1 are provided on the outer side wall of the right-angle fixing frame 3. The anti-slip sawtooth bodies 3-1 are in contact with the anti-slip grooves 12, which can improve the stability of the right-angle fixing frame 3 and make it not easy to shift after the right-angle fixing frame 3 is fixed. Several fixing holes 3-2 are provided on the right-angle fixing frame 3, and the fixing holes 3-2 can allow the self-tapping bolts 4 to penetrate, so as to fix the right-angle fixing frame 3.

[0036] As Figure 5As shown, in this specific embodiment, the horizontal heat preservation strip 1 and the vertical heat preservation strip 2 are used to improve the heat preservation performance. After filling, the heat preservation performance can be directly improved, and the phenomena of falling off and cracking are not likely to occur. The specific technical solutions are as follows: The horizontal heat preservation strip 1 and the vertical heat preservation strip 2 have the same structure, and both include an outer frame body 1-1, a strengthening mesh 1-2, a heat insulation layer 1-3, a heat preservation layer 1-4, and a connecting strengthening rod 1-5; A strengthening mesh 1-2 is arranged on the inner side wall of the outer frame body 1-1. The outer frame body 1-1 can improve the overall strength and stability, and the strengthening mesh 1-2 can improve the strength and is not likely to crack. A heat insulation layer 1-3 is arranged on the inner side wall of the strengthening mesh 1-2. The heat insulation layer 1-3 can achieve heat insulation. A heat preservation layer 1-4 is arranged inside the heat insulation layer 1-3. The heat preservation layer 1-4 can improve the heat preservation performance. The two ends of the connecting strengthening rod 1-5 are respectively connected to the inner side wall of the strengthening mesh 1-2. The connecting strengthening rod 1-5 can improve the connection strength between the strengthening mesh 1-2, the heat insulation layer 1-3, and the heat preservation layer 1-4; The strengthening mesh 1-2 is a nylon mesh body or a steel wire mesh body; The heat insulation layer 1-3 is an aluminum foil sheet, and the aluminum foil sheet can improve the heat insulation performance; The heat preservation layer 1-4 is a polyurethane heat preservation board; As Figure 6 shown, the connecting strengthening rod 1-5 includes a connecting cross bar 1-51 and a strengthening longitudinal rod 1-52; Several strengthening longitudinal rods 1-52 are evenly arranged on the outer side wall of the connecting cross bar 1-51. The connecting cross bar 1-51 can improve the strength of the outer frame body 1-1 and make it not likely to deform.

[0037] When filling this specific embodiment, as Figure 1As shown in the figure, first cut the length of the horizontal heat preservation strip 1 according to the length of the gap between the wall and the electrical box 5. Then install the upper and lower horizontal heat preservation strips 1 first. When installing, bond them with glue. After bonding, drill holes in the fixing grooves 11 of the horizontal heat preservation strip 1 and fix the horizontal heat preservation strip 1 on the wall with bolts, which can improve the fixing strength of the horizontal heat preservation strip 1. At the same time, in the case where the bolts cannot be fixed, it can also be fixed without bolts. After the horizontal heat preservation strip 1 is fixed, measure the distance between the two horizontal heat preservation strips 1, cut the length of the vertical heat preservation strip 2 according to the measured data, and then bond the vertical heat preservation strip 2 to the wall. Moreover, the vertical heat preservation strip 2 can support the two horizontal heat preservation strips 1. After the vertical heat preservation strip 2 is bonded, it can be fixed on the wall with bolts, that is, fixed with bolts. In the case where the bolts cannot be fixed, it can also be fixed without bolts. Then install the right-angle fixing bracket 3 at the connection of the horizontal heat preservation strip 1 and the vertical heat preservation strip 2, which can strengthen the connection strength between the horizontal heat preservation strip 1 and the vertical heat preservation strip 2. Then measure the distance between the two vertical heat preservation strips 2 again. It is necessary to cut the length of the inner horizontal heat preservation strip 1 and bond the horizontal heat preservation strip 1 to the inner side wall of the outer horizontal heat preservation strip 1. When bonding, inject sealant into the fixing groove 11 of the outer horizontal heat preservation strip 1 to achieve sealing in this way. Repeat this process to cut and install the inner vertical heat preservation strip 2 and the inner horizontal heat preservation strip 1. When the horizontal heat preservation strip 1 and the vertical heat preservation strip 2 cannot fill the gap at one time, it is necessary to bond again on the outside of the horizontal heat preservation strip 1 and the vertical heat preservation strip 2, and it is necessary to ensure that the gap is fully filled, which can achieve rapid filling of the gap and achieve heat preservation after filling. After filling, perform external sealing and fixing to ensure the overall heat preservation performance of the building exterior wall heat preservation layer.

[0038] As Figure 7 shown in the figure, the gap is not a regular rectangular shape and is filled according to needs. When filling, it is necessary to ensure that the horizontal heat preservation strip 1 and the vertical heat preservation strip 2 are installed in a butt joint manner and fixed by the right-angle fixing bracket 3. It can support the horizontal heat preservation strip 1 through the vertical heat preservation strip 2, so that the horizontal heat preservation strip 1 is not prone to cracking and falling off, and it can ensure the stability after installation and is not prone to falling off and cracking.

[0039] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.

[0040] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
