Description

Technical Field

[0001] The utility model relates to a plate - type heat - preservation structure for a large - scale air - conditioned room, belonging to the technical field of building heat - preservation. Background Technique

[0002] At present, air - conditioned rooms on the market are mainly divided into two types: framed and frameless. Framed air - conditioned rooms usually consist of columns forming a frame, and panels are inlaid in the frame. However, due to the clearance fit, this design has problems of poor airtightness and high air leakage rate. In contrast, frameless air - conditioned rooms support the room body through the mutual cooperation of plastic - steel profiles, but their disadvantage is insufficient stiffness, low ability to withstand static pressure, and easy deformation.

[0003] In addition, both of these two types of air - conditioned rooms are insufficient in heat insulation and heat resistance. These defects limit their application in industrial fields with high requirements for heat resistance. Especially in building structures, if the connecting components or the heat - insulating layer are interrupted, a so - called "cold - bridge" phenomenon will occur. Ice and frost are likely to form at the cold - bridge. If not properly treated, a large amount of heat will enter the air - conditioned room and gradually expand, eventually possibly causing damage to the heat - insulating layer and structural components, and even the overall destruction of the air - conditioned room.

[0004] In view of these problems of the existing air - conditioned rooms, there is an urgent need to develop a new type of air - conditioned room, which should have better airtightness, heat - insulation effect and heat resistance. This new type of air - conditioned room needs to meet the requirements of the industrial field for large - scale air - conditioned rooms, ensure stable operation under various environmental conditions, and at the same time improve energy efficiency and extend service life. Summary of the Invention

[0006] To achieve the above - mentioned technical purpose, the utility model adopts the following technical solutions:

[0008] The frame beams and the exposed beams are spliced into a frame assembly for fixing the cold storage boards;

[0009] Both the frame beams and the exposed beams are provided with cavities, and there is heat - preservation material inside the cavities;

[0010] The heat - preservation material and the heat - preservation material of the cold storage boards together form a continuous heat - preservation layer.

[0011] Preferably, the cavity of the frame beam is an inner isolation cavity of the frame beam, close to the inner surface of the cold storage board;

[0012] The cavity of the visible beam is the internal isolation cavity of the visible beam, which is close to the inner surface of the cold storage board.

[0013] Both the internal isolation cavity of the frame beam and the internal isolation cavity of the visible beam are communicated with the cold bridge injection port, so as to inject the thermal insulation material into the internal isolation cavity of the frame beam and the internal isolation cavity of the visible beam through the cold bridge injection port.

[0018] The horizontal inner support plate, the vertical inner support plate, two second connecting plates of the frame beam, and the inclined plate enclose to form the internal isolation cavity of the frame beam;

[0019] The horizontal inner support plate and the vertical inner support plate are perpendicular to each other and are respectively used to fix one of the two vertically installed cold storage boards.

[0020] Preferably, the inclined plate is arranged between the connection points of two first connecting plates of the frame beam and two second connecting plates of the frame beam.

In addition, this structure has the characteristics of fire prevention, flame retardancy, and high temperature resistance, and is suitable for industrial fields with high heat resistance requirements. The mode of splicing and integrally forming not only improves the stability of the frame but also facilitates assembly and maintenance. The misaligned design of the C-shaped groove openings of the fasteners improves the locking degree between the cold storage board and the frame, further preventing the contact between the air outside the unit and the air inside the frame, and effectively enhancing the thermal insulation performance.

[0034] The technical content of the present utility model will be described in detail below with reference to the drawings and specific embodiments.

[0035] First Embodiment

[0036] As Figure 1As shown in the figure, an embodiment of the present utility model discloses a plate-type thermal insulation structure for a large air-conditioned room, which includes a frame beam 11, a visible beam 12, and a cold storage board 13. The frame beam 11 and the visible beam 12 are spliced into a frame assembly for fixing the cold storage board 13, thereby forming an overall enclosed cold storage or air-conditioned room. In order to further improve the strength and stiffness of the frame assembly, a plurality of vertically arranged square steel pipes 5 are also installed on the inner surface (indoor surface) of the cold storage board. The frame assembly provided by the embodiment of the present utility model adopts a cold bridge-breaking design, so that the technical effects of convenient assembly and moisture retention and pressure resistance can be achieved.

[0037] As Figure 2 shown, the frame beam 11 is an aluminum alloy profile, which is used to vertically connect two cold storage boards 13. Combining Figure 3 shown, the frame beam 11 is strip-shaped, and its cross-section is approximately square (it can also be rectangular). In the cross-section, the frame beam 11 includes a horizontal inner support plate 111, a vertical inner support plate 112, a horizontal outer support plate 113, a vertical outer support plate 114, a fastener 115, a first frame beam connecting plate 116, an inclined plate 117, and a second frame beam connecting plate 118.

[0038] The horizontal inner support plate 111 and the vertical inner support plate 112 are vertically connected to form a right angle, which is used to fix the inner surfaces of two mutually perpendicular cold storage boards 13. The horizontal outer support plate 113 and the vertical outer support plate 114 are vertically connected and are approximately coplanar with the outer surfaces of two mutually perpendicular cold storage boards 13 respectively. In other words, the vertically arranged cold storage board 13 is located between the vertical inner support plate 112 and the vertical outer support plate 114; the horizontally arranged cold storage board 13 is located between the horizontal inner support plate 111 and the horizontal outer support plate 113.

[0039] One of the two fasteners 115 is connected between the horizontal outer support plate 113 and the first frame beam connecting plate 116; the other is connected between the vertical outer support plate 114 and the first frame beam connecting plate 116. Each fastener 115 is C-shaped, and the opening faces outward and adopts a dislocation design, which is convenient for the installation of the card strip and the sealing strip 7 to lock the cold storage board 13 into the frame assembly and form a seal.

[0040] One end of each frame beam first connecting plate 116 is perpendicularly connected to the clamping member 115, and the other end is coplanarly connected to the frame beam second connecting plate 118. Moreover, an inclined plate 117 is provided between the connection points of the two frame beam first connecting plates 116 and the two frame beam second connecting plates 118. The other ends of the two frame beam second connecting plates 118 are respectively perpendicularly connected to the horizontal inner connecting plate 111 and the vertical inner connecting plate 112. In this way, a frame beam inner isolation cavity 110A is formed by enclosing the horizontal inner support plate 111, the vertical inner support plate 112, the two frame beam second connecting plates 118, and the inclined plate 117. The frame beam inner isolation cavity 110A is a substantially enclosed cavity. At the same time, a frame beam outer isolation cavity 110B is formed by enclosing the horizontal outer support plate 113, the vertical outer support plate 114, the clamping member 115, the frame beam first connecting plate 116, and the inclined plate 117. As can be seen from the figure, the frame beam inner isolation cavity 110A is close to the inner surface of the cold storage board 13 (i.e., close to the indoor surface); the frame beam outer isolation cavity 110B is far from the inner surface of the cold storage board 13 (i.e., close to the outdoor surface).

[0041] At positions of the two frame beam second connecting plates 118 close to the horizontal inner connecting plate 111 and the vertical inner connecting plate 112, cold bridge break injection ports 10 are opened (the opening directions face the cold storage board), and are all communicated with the frame beam inner isolation cavity 110A, and are used for injecting heat preservation materials 8 into the frame beam inner isolation cavity 110A (the frame beam outer isolation cavity 110B is a cavity and there is no heat preservation material inside). The cold bridge break injection ports 10 respectively face the cold storage board 13. In this embodiment, the frame beam inner isolation cavity 110A is filled with high-density polyurethane foam material. As Figure 2 shown, the frame beam inner isolation cavity 110A is close to the inner surface of the cold storage board 13, and forms a continuous heat preservation layer (not disconnected) with the heat preservation material of the cold storage board 13, so that the frame beam 11 forms a cold bridge break structure.

[0042] More preferably, reinforcing ribs 9 are provided on the inner side walls of the frame beam inner isolation cavity 110A, that is, on the horizontal inner support plate 111, the vertical inner support connecting plate 112, and the inclined plate 117, so that the cold bridge break structure of the frame beam 11 is more stable.

[0043] As Figure 4 and Figure 5 shown, the exposed beam 12 is a long strip-shaped aluminum alloy profile, and is used for horizontally connecting two cold storage boards 13.

[0044] In cross-section, the exposed beam 12 includes a first horizontal connecting plate 121, a second horizontal connecting plate 122, a first vertical connecting plate 123, a second vertical connecting plate 124, a baffle 125, and a clamping member 115.

[0045] The first horizontal connecting plate 121 and the second horizontal connecting plate 122 are arranged in parallel, and both ends are perpendicularly connected to the first vertical connecting plate 123. At the middle position of the first vertical connecting plate 123 between the first horizontal connecting plate 121 and the second horizontal connecting plate 122, and facing the cold storage board 13, a cold bridge injection port 10 is provided. The top end of the first vertical connecting plate 123 is horizontally connected to the second vertical connecting plate 124, and the bottom end is perpendicularly connected to the baffle 125. The extending directions of the two baffles 125 are opposite, respectively forming an L-shaped structure extending to both sides of the first vertical connecting plate 123. The two fasteners 115 have openings facing upward and are symmetrically and juxtaposedly connected to the top end of the second vertical connecting plate 124. The first horizontal connecting plate 121, the second horizontal connecting plate 122, and the two first vertical connecting plates 123 enclose a cavity 120A inside the exposed beam. The first vertical connecting plate 123, the two second vertical connecting plates 124, and the two fasteners 115 enclose a cavity 120B outside the exposed beam. Among them, the cavity 120A inside is filled with a heat insulating material 8 (for example, high-density polyurethane foam material) through the cold bridge injection port 10, forming a continuous heat insulating layer with the heat insulating materials of the two cold storage boards 13 in the horizontal direction. Therefore, a cold bridge structure is formed inside the exposed beam 12.

[0046] Preferably, reinforcing ribs 9 are provided on the inner side walls of the cavity 120A inside the exposed beam, that is, on the first horizontal connecting plate 121, the second horizontal connecting plate 122, and the first vertical connecting plate 123, making the cold bridge structure of the exposed beam 12 more stable.

[0047] As described above, cavities (the cavity 110A inside the framed beam and the cavity 120A inside the exposed beam) are provided in both the framed beam 11 and the exposed beam 12 in the embodiments of the present invention. There is a heat insulating material inside, forming a continuous heat insulating layer together with the heat insulating materials of the cold storage board 13, thus avoiding a cold bridge (also known as a heat bridge) and forming a cold bridge-breaking design. Therefore, the unit frame formed by the splicable framed beam 11, the exposed beam 12, and the cold storage board 13 has excellent thermal performance such as low thermal conductivity, fire resistance, flame retardancy, and high temperature resistance, and is suitable for cold storages or air-conditioned rooms of various specifications / lengths.

[0048] Second Embodiment

[0049] As Figure 6 and Figure 7 shown, since the length of the cold storage or air-conditioned room may be very long, the length of the framed beam 11 needs to be increased accordingly. For this reason, in this embodiment, a connector 20 is used to connect two framed beams 11, and at the same time, the connection part of the two framed beams 11 is kept flat without affecting the sealing performance between the cold storage board and the frame assembly.

[0050] Reference Figure 7, the size of the connecting member 20 is adapted to the inner contour of the outer isolation cavity 110B of the frame beam 11 so as to be installed in the outer isolation cavity 110B of the frame beam 11. The connecting member 20 includes a plug-in inclined plate 21, a plug-in connecting plate 22 and a plug-in fixing plate 23. The two plug-in connecting plates 22 are connected to both ends of the plug-in inclined plate 21 and are respectively parallel to the horizontal outer support plate 113 and the vertical outer support plate 114. That is, the two plug-in connecting plates 22 are perpendicular to each other.

[0051] The two plug-in fixing plates 23 are respectively vertically connected to the other ends of the two plug-in connecting plates 22 and are respectively parallel to the two frame beam first connecting plates 116 so as to connect the frame beam first connecting plates 116 and the plug-in connecting plates 23 by screws, thereby connecting the connecting member 20 and the frame beam 11 into one body.

[0052] Those skilled in the art can understand that as an alternative, the plug-in inclined plate 21 of the connecting member 20 can also be omitted. That is, the plug-in connecting plate 22 and the plug-in fixing plate 23 are directly connected (refer to Figure 6 ).

[0053] It can be seen that the frame assembly in the embodiment of the present utility model adopts a cold bridge breaking design, which can effectively prevent the transfer of cold and heat between indoors and outdoors, thereby preventing the direct contact between the outer wall and the air inside the unit and reducing the conduction loss inside and outside the unit. In addition, the fastener 115 adopts a C-shaped groove offset design and embeds the card strip and the card strip sealing strip 7, which can not only make the locking degree of the cold storage board and the frame higher, but also effectively prevent the contact between the air outside the unit and the air inside the frame, effectively improving the heat preservation performance of the air conditioner unit.

[0054] Compared with the prior art, the large air-conditioning room plate-type heat preservation structure provided by the present utility model realizes a number of technical effects through a unique design. First of all, by filling the aluminum profile with polyurethane foam material, a cold bridge breaking structure is formed, effectively blocking the transfer of cold and heat, thereby improving the heat insulation effect and heat resistance. Secondly, the structural design enhances the airtightness of the air-conditioning room, reduces air leakage, and at the same time, due to the setting of the continuous heat preservation layer, the cold bridge phenomenon is avoided, further improving the heat preservation efficiency. In addition, the structure has the characteristics of fire prevention, flame retardancy and high temperature resistance, and is suitable for industrial fields with high heat resistance requirements. The splicing and integral forming mode not only improves the stability of the frame, but also facilitates assembly and maintenance. The C-shaped groove offset design of the fastener improves the locking degree of the cold storage board and the frame, further preventing the contact between the air outside the unit and the air inside the frame, and effectively improving the heat preservation performance.

[0055] The above has given a detailed description of the plate-type heat insulation structure for large air-conditioned rooms provided by the present utility model. For those of ordinary skill in the art, any obvious changes made to it without departing from the substantial content of the present utility model will constitute an infringement of the patent right of the present utility model and shall bear corresponding legal responsibilities.
