Description
Technical Field
[0001] This application relates to the field of cold storage construction technology, and in particular to a method for thermal insulation construction of steel column joints through cold storage. Background Technology
[0002] The fans and other related equipment in cold storage are usually installed on the top of the cold storage, so a roof is usually installed on top of the cold storage for covering.
[0003] In a cold storage structure, columns need to pass through the cold storage and support the roof. However, this results in a gap between the columns and the cold storage. Even with the addition of sealing measures, there is still a certain amount of cold air leakage. Furthermore, the steel columns themselves also transmit energy, affecting the inside and outside of the cold storage. Summary of the Invention
[0004] The purpose of this application is to provide a method for thermal insulation construction of steel column joints through cold storage, so as to improve the potential problem of cold air leakage caused by the gap between the column and the cold storage.
[0005] Firstly, this application provides a method for thermal insulation construction of steel column joints penetrating cold storage, which adopts the following technical solution: A method for thermal insulation construction of a steel column joint penetrating a cold storage facility includes the following steps: S1, constructing the cold storage facility and reserving holes to accommodate the steel column; S2, constructing the steel column and wrapping an insulation layer around the top of the steel column, the insulation layer covering the top and sides of the steel column and the top of the cold storage facility; S3, constructing a roof above the cold storage facility and the steel column.
[0006] By adopting the above technical solution, during construction, the steel columns are isolated from other structures by covering the top and sides of the steel columns and the top of the cold storage with the insulation layer, reducing the possibility of cold air leakage. At the same time, it can also reduce the transfer of heat from the steel columns to the cold storage, ensuring the independence of the cold storage.
[0007] Optionally, the insulation layer includes a load-bearing insulation layer, a first insulation layer, and a second insulation layer that are connected to each other. The load-bearing insulation layer is installed on the top surface of the steel column, the first insulation layer is installed on the side of the steel column, and the second insulation layer is installed on the top surface of the cold storage.
[0008] Optionally, the load-bearing insulation layer includes two load-bearing steel plates, several load-bearing steel rods are connected between the two load-bearing steel plates, a third insulation layer is filled between the two load-bearing steel plates, the third insulation layer is connected to the first insulation layer, one load-bearing steel plate is connected to the top surface of the steel column, and the other load-bearing steel plate is connected to the roof.
[0009] Through the above technical solution, two load-bearing steel plates and several load-bearing steel rods support the roof, while the third insulation layer facilitates temperature isolation. At the same time, the third insulation layer can also be easily connected to the first insulation layer to isolate the steel columns from other structures above the cold storage.
[0010] Optionally, in step S2, when installing the insulation layer, first install the load-bearing insulation layer on the top surface of the steel column, and then connect the first insulation layer and the third insulation layer. When connecting, first inject foam glue between the first insulation layer and the third insulation layer using an integrated injection gun, and then apply waterproof glue to the first insulation layer and the third insulation layer using an integrated injection gun.
[0011] The above technical solution uses foam adhesive and waterproof adhesive to connect the first and third insulation layers, while also reducing the possibility of cold air leakage.
[0012] Optionally, the integrated injection and brush gun includes a handle and a foam glue container and a waterproof glue container mounted on the handle. The foam glue container is equipped with an injection needle, the waterproof glue container is equipped with a brush, and the handle is equipped with an injection component to push the glue in the foam glue container or the waterproof glue container into the injection needle or the brush.
[0013] The above technical solution uses an injection needle and a brush to inject foam adhesive and apply waterproof adhesive respectively, integrating the two types of adhesive into a single glue gun. This reduces the tools that operators need to carry and eliminates the need to switch glue guns during operation, thus improving ease of use.
[0014] Optionally, the injection assembly includes a wrench and two sets of pistons, push plates, and return springs. Each of the foam glue container and the waterproof glue container has a set of pistons, push plates, and return springs. A stopper rod is coaxially connected to the piston. The push plate and return spring are both sleeved on the stopper rod. A fixing plate is fixedly connected to each of the foam glue container and the waterproof glue container. The return spring is located between the push plate and the fixing plate. The wrench is hinged to a handle. A push rod for pushing the push plate is connected to the wrench. When the push plate moves towards the piston, it locks the stopper rod. When the push plate moves away from the piston, it releases the stopper rod.
[0015] By adopting the above technical solution, when injection is required, the wrench is pulled, and the wrench swings, causing the push rod to swing, which in turn pushes the push plate towards the piston. At this time, the push plate locks the stopper rod, pushing the stopper rod towards the piston, which in turn drives the piston to move, pushing the glue to move. After the glue is fed, the wrench is released. At this time, the return spring pushes the push plate away from the piston, while the stopper rod remains stationary due to the friction between the piston and the foam glue container or waterproof glue container, which causes the push plate to return to its original position while the stopper rod remains stationary. At the same time, the push plate also drives the wrench to return to its original position, which facilitates the next glue feeding.
[0016] Optionally, the wrench has a sliding groove along the line connecting the foam glue bucket and the waterproof glue bucket, and the push rod slides in the sliding groove so that the push rod enters the foam glue bucket or the waterproof glue bucket.
[0017] By adopting the above technical solution, the push rod slides in the sliding groove to enter the foam glue bucket or waterproof glue bucket, which facilitates the movement of the corresponding push plate and realizes the feeding of different glues.
[0018] Optionally, the pusher plate has a conical hole, and the conical hole has a conical blade. Multiple conical blades are arranged along the circumference of the conical hole, and the multiple conical blades are arranged to fit against the inner wall of the conical hole. The large end of the conical hole faces the piston.
[0019] Through the above technical solution, by cooperating with the conical plate and the conical hole, when the push plate moves toward the piston, the push plate locks the plug rod, and when the push plate moves away from the piston, the push plate releases the plug rod, thereby realizing the reciprocating feeding of glue.
[0020] Optionally, a heating module is connected between the waterproof glue bucket and the foam glue bucket, and the heating module is set in contact with the side wall of the waterproof glue bucket and the foam glue bucket.
[0021] By adopting the above technical solution, the waterproof glue bucket and the foam glue bucket are heated by the heating module to maintain the temperature of the glue inside the waterproof glue bucket and the foam glue bucket.
[0022] Optionally, a brush box is connected to the waterproof glue bucket, the brush is installed on the brush box, and the waterproof glue bucket is in communication with the brush box.
[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. During construction, by covering the top and sides of the steel columns and the top of the cold storage with an insulation layer, the steel columns are isolated from other structures, reducing the possibility of cold air leakage. At the same time, it can also reduce the transfer of heat from the steel columns to the cold storage, ensuring the independence of the cold storage. 2. Two load-bearing steel plates and several load-bearing steel rods provide support for the roof, while the third insulation layer facilitates temperature isolation. At the same time, the third insulation layer can also be easily connected to the first insulation layer to isolate the steel columns from other structures above the cold storage. 3. The first and third insulation layers are connected using foam adhesive and waterproof adhesive, which also helps to reduce the possibility of cold air leakage; 4. Foam adhesive is injected and waterproof adhesive is applied by using an injection needle and a brush respectively. The two types of adhesive are integrated into one glue gun, which reduces the tools that operators need to carry and eliminates the need to switch glue guns during operation, thus improving the ease of operation. 5. When injection is required, pull the wrench. The wrench swings, causing the push rod to swing, which in turn pushes the push plate towards the piston. At this time, the push plate locks the stopper rod, pushing the stopper rod towards the piston, which in turn moves the piston and pushes the glue. After the glue is fed, release the wrench. At this time, the return spring pushes the push plate away from the piston, while the stopper rod remains stationary due to the friction between the piston and the foam glue container or waterproof glue container. This causes the push plate to return to its original position while the stopper rod remains stationary. At the same time, the push plate also drives the wrench to return to its original position, which is convenient for the next glue feeding. 6. The push rod slides in the sliding groove to enter the foam glue bucket or waterproof glue bucket, which facilitates the movement of the corresponding push plate to feed different glues; 7. Through the cooperation of the conical plate and the conical hole, when the push plate moves toward the piston, the push plate locks the plug rod, and when the push plate moves away from the piston, the push plate releases the plug rod, thereby realizing the reciprocating feeding of glue; 8. The waterproof glue bucket and foam glue bucket are heated by the heating module to maintain the temperature of the glue inside the waterproof glue bucket and foam glue bucket.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1
[0032] Firstly, this application discloses a method for thermal insulation construction of steel column joints penetrating cold storage.
[0033] A method for thermal insulation construction of steel column joints through cold storage, referring to Figures 1 to 5 It includes the following steps: S1. Construct cold storage 1 and reserve holes to accommodate steel columns 2.
[0034] S2. Construct steel column 2 and wrap the top of steel column 2 with an insulation layer, covering the top and sides of steel column 2 and the top of cold storage 1.
[0035] The insulation layer includes an interconnected load-bearing insulation layer 21, a first insulation layer 22, and a second insulation layer 23. The load-bearing insulation layer 21 is installed on the top surface of the steel column 2, the first insulation layer 22 is installed on the side of the steel column 2, and the second insulation layer 23 is installed on the top surface of the cold storage 1. The insulation layer can be made of polyurethane.
[0036] Specifically, the load-bearing insulation layer 21 includes two load-bearing steel plates 24, with several load-bearing steel rods 25 connecting the two load-bearing steel plates 24. A third insulation layer 26 is filled between the two load-bearing steel plates 24 and is connected to the first insulation layer 22. One load-bearing steel plate 24 is connected to the top surface of the steel column 2, and the other load-bearing steel plate 24 is connected to the roof 3. The two load-bearing steel plates 24 and the several load-bearing steel rods 25 provide support for the roof 3, while the third insulation layer 26 facilitates temperature isolation. At the same time, the third insulation layer 26 is also easy to connect with the first insulation layer 22, thus isolating the steel column 2 from other structures above the cold storage 1.
[0037] It should be noted that during the production of the load-bearing insulation layer 21, the load-bearing steel plate 24 is first connected to the load-bearing steel rod 25, and then placed into the mold to cast the third insulation layer 26.
[0038] When installing the insulation layer, first install the load-bearing insulation layer 21 on the top surface of the steel column 2. Then connect the first insulation layer 22 and the third insulation layer 26. During the connection, first inject foam adhesive between the first insulation layer 22 and the third insulation layer 26 using an integrated injection gun, and then immediately apply waterproof adhesive to the first insulation layer 22 and the third insulation layer 26 using the same injection gun. The connection between the first insulation layer 22 and the third insulation layer 26 is achieved through the foam adhesive and the waterproof adhesive, which also helps to reduce the possibility of cold air leakage.
[0039] Specifically, the integrated injection and brush gun includes a handle 4 and a foam glue container 5 and a waterproof glue container 6 mounted on the handle 4. The foam glue container 5 is equipped with an injection needle 51, and the waterproof glue container 6 is equipped with a brush 62. The handle 4 is equipped with an injection component 7 to push the glue in the foam glue container 5 or the waterproof glue container 6 into the injection needle 51 or the brush 62. The injection needle 51 and the brush 62 are used to inject foam glue and apply waterproof glue respectively. By integrating the two types of glue into one glue gun, the number of tools that the operator needs to carry is reduced, and there is no need to switch glue guns during operation, which improves the convenience of operation.
[0040] More specifically, the injection assembly 7 includes a wrench 71, two sets of pistons 72, a pusher 73, and a return spring 74. The foam glue container 5 and the waterproof glue container 6 each have a set of pistons 72, pushers 73, and return springs 74. A stopper rod is coaxially connected to the piston 72. The pusher 73 and the return spring 74 are both sleeved on the stopper rod. A fixing plate 75 is fixedly connected to the foam glue container 5 and the waterproof glue container 6 respectively. The return spring 74 is located between the pusher 73 and the fixing plate 75. The wrench 71 is hinged to the handle 4. A push rod 711 for pushing the pusher 73 to move is connected to the wrench 71. When the pusher 73 moves toward the piston 72, the pusher 73 locks the stopper rod. When the pusher 73 moves away from the piston 72, the pusher 73 releases the stopper rod. When injection is required, wrench 71 is pulled, and the swing of wrench 71 causes push rod 711 to swing, which in turn pushes push plate 73 toward piston 72. At this time, push plate 73 locks the stopper rod, pushing the stopper rod toward piston 72, which in turn drives piston 72 to move, pushing the glue to move. After the glue is fed, wrench 71 is released. At this time, return spring 74 pushes push plate 73 to move away from piston 72, while the stopper rod remains stationary due to the friction between piston 72 and foam glue container 5 or waterproof glue container 6, which causes push plate 73 to return to its original position and the stopper rod to remain stationary. At the same time, push plate 73 also drives wrench 71 to return to its original position, which is convenient for the next glue feeding.
[0041] The wrench 71 has a sliding groove 712 along the line connecting the foam glue container 5 and the waterproof glue container 6. The push rod 711 slides within the sliding groove 712 to allow it to enter either the foam glue container 5 or the waterproof glue container 6. The sliding of the push rod 711 within the sliding groove 712 facilitates its entry into the foam glue container 5 or the waterproof glue container 6, thereby promoting the movement of the corresponding push plate 73 and enabling the feeding of different types of glue.
[0042] The pusher plate 73 has a conical hole 731 inside, and a conical plate 732 is provided inside the conical hole 731. Multiple conical plates 732 are arranged around the circumference of the conical hole 731, and the multiple conical plates 732 are set to fit against the inner wall of the conical hole 731. The large end of the conical hole 731 faces the piston 72. Through the cooperation between the conical plates 732 and the conical hole 731, when the pusher plate 73 moves towards the piston 72, the pusher plate 73 locks the stop rod, and when the pusher plate 73 moves away from the piston 72, the pusher plate 73 releases the stop rod, realizing the reciprocating feeding of glue.
[0043] A heating module 8 is connected between the waterproof glue bucket 6 and the foam glue bucket 5. The heating module 8 is fitted against the side walls of the waterproof glue bucket 6 and the foam glue bucket 5. The heating module 8 heats the waterproof glue bucket 6 and the foam glue bucket 5 to maintain the temperature of the glue inside them.
[0044] It should be noted that a brush box 61 is fixedly connected to the waterproof glue bucket 6, and a brush 62 is installed on the brush box 61. The waterproof glue bucket 6 and the brush box 61 are connected so that the glue can enter the brush box 61 from the waterproof glue bucket 6.
[0045] S3. Construct roof 3 above cold storage 1 and steel column 2.
[0046] Working principle: By covering the top and sides of the steel column 2 and the top of the cold storage 1 with the insulation layer, the steel column 2 is isolated from other structures, reducing the possibility of cold air leakage. At the same time, it can also reduce the transfer of heat from the steel column 2 to the cold storage 1, ensuring the independence of the cold storage 1.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
