Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a countersunk head anti-cold bridge bolt structure for a cold storage board wall of an indoor ski resort, which is suitable for the construction of a cold storage board wall. Background Art

[0002] In recent years, skiing has become more and more popular among the public. Currently, most of the ski resorts in my country are outdoor ski resorts, and most of them are located in the north. They are open to the public according to the duration of the snow season, which usually lasts only 2-3 months, and cannot meet the needs of consumers for skiing. In view of the current situation of indoor ski resort construction, more and more commercial places with huge consumption potential in cities, such as commercial complexes, cultural and tourism cities, etc., have begun to vigorously build large indoor ski venues.

[0003] Thermal insulation system is an important part of the construction of indoor ski resorts. The thermal insulation method used in indoor ski resorts is usually to install cold storage panels on the inside and fix them on the keel purlins with bolts. On the one hand, there are gaps in the bolt connection parts, which causes the cold air inside the venue to leak, which not only increases energy consumption, but also reduces the service life of snowmaking equipment. On the other hand, the internal cold air leaks from the bolt connection and combines with the external hot air to form a cold bridge condensation and ice hanging phenomenon, causing a surge in the energy consumption and maintenance costs of the venue building. In addition, the traditional bolts used for the installation of cold storage panels are mushroom head bolts, which are protruding on the inside of the venue, affecting the spray painting or paving effect of the interior wall panel surface murals. Utility Model Content

[0004] In order to solve the problems of cold leakage and cold bridge effect at the connecting bolts of cold storage panels, and to provide convenience for subsequent wall decoration, the purpose of the utility model is to provide a countersunk anti-cold bridge bolt structure for the wall of cold storage panels in an indoor ski resort. The countersunk anti-cold bridge bolt has an outer nylon insulating sleeve, which is in close contact with the rock wool of the cold storage panel, preventing cold and warm air from contacting in the connecting gap, effectively preventing the cold bridge effect, reducing condensation and ice hanging, and preventing cold leakage, greatly saving energy consumption and reducing subsequent maintenance costs.

[0005] To further achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a countersunk anti-cold bridge bolt structure for the cold storage panel wall of an indoor ski resort, comprising a connecting piece and a cold storage panel, wherein the connecting piece is fixed on a keel purlin, and the countersunk anti-cold bridge bolt comprises a flat head screw with a cavity therein and a screw placed in the cavity of the flat head screw, wherein the screw is threadedly connected to the flat head screw;

[0006] The end of the screw rod extending out of the flat head screw is successively sleeved with a single nut and a double nut, and a rubber gasket and a steel gasket A are successively sleeved on the screw rod close to the flat head screw; the section of the screw rod embedded in the range of the cold storage panel and the flat head screw are wrapped with a nylon insulating sleeve.

[0007] Furthermore, the connecting piece is clamped and fixed by a single nut and a double nut.

[0008] Furthermore, the cold storage plate is fixed by a single nut, a screw rod and a flat head screw.

[0009] Preferably, a steel gasket B is sleeved on the screw rod at one side close to the connecting piece.

[0010] Optionally, the outermost layer of the flat head screw end is wrapped with a galvanized sleeve cap.

[0011] Furthermore, the flat head screws are embedded in the cold storage panel.

[0012] Compared with the prior art, the specific beneficial effects of the utility model are:

[0013] 1. The countersunk anti-cold bridge bolts have an outer nylon insulation sleeve, which is in close contact with the rock wool of the cold storage board, preventing cold and warm air from contacting in the connection gap, which can effectively prevent the cold bridge effect, reduce condensation and ice hanging, and prevent cold leakage, greatly saving energy consumption and reducing later maintenance costs.

[0014] 2. The countersunk anti-cold bridge bolts use flat head screws, which are embedded in the cold storage panels. The wall facade is flat and does not affect the spray painting or paving effect of the interior wall panel surface murals, providing convenience for decoration. BRIEF DESCRIPTION OF THE DRAWINGS
