Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-10, the present invention provides a split type double-layer insulation stack, which comprises a structural layer 1 and an insulation layer 2; the structural layer 1 comprises a base and a cover 105; the cover body 105 covers the middle upper part of the front surface of the base; the base comprises a back plate 101 attached to the wall; the middle upper part of the rear back plate 101 is provided with an inverted U-shaped first baffle plate 102; the lower part of the rear back plate 101 is connected with a U-shaped second baffle plate 104; the open end of the first baffle 102 and the open end of the second baffle 104 intersect; the heat preservation layer 2 is nested in the base, and a cavity for accommodating the water pipe 3 is formed in the middle of the heat preservation layer 2.

In fig. 8 and 9, the portion of the backplate 101 surrounded by the first and

second baffles

102 and 104 is hollowed out, and includes only the portion located outside the first baffle 102 (i.e., the backplate 101 has an inverted U-shaped configuration). This has the advantage of saving material on the one hand and of being easy to install on the other hand. In fact, most area of the middle part of the back plate 101 can be reserved, and only the part through which the water pipe 3 passes is hollowed, which is beneficial to enhancing the overall structural stability. The specific shape of the backplate 101 is not limited in the present invention, and both of the above structures are within the scope and disclosure of the present invention.

The base is an integrally formed structure, and the backboard 101, the first baffle plate 102 and the second baffle plate 104 are all components of the base. Preferably, the base is made of glass fiber reinforced plastic. Glass fiber reinforced plastic has high strength and light weight, and has density about 1.8 times that of water, aluminum 2.7 times that of water, and steel 7.8 times that of water. In contrast, when the product is made of glass fiber reinforced plastics, the product is lighter than a metal material. The glass fiber reinforced plastic has light weight, high strength and relative density of 1.5-2.0, only 1/4-1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared with high-grade alloy steel. The chemical properties such as corrosion resistance and the like are good, and the corrosion resistance is good for most of acid-base salt solutions, and the corrosion resistance is good for the resistance to the atmosphere, water, acid, alkali, salt with common concentration and various oils and solvents. The glass fiber reinforced plastic has good electrical property, is an excellent insulating material, has low thermal conductivity, is 1.25-1.67 kJ/(m.h.K) at room temperature, is only 1/100-1/1000 of metal, is an excellent heat insulating material, and is an ideal heat protection and ablation resistant material under the condition of instantaneous ultrahigh temperature. The manufacturability is excellent, and the forming process can be flexibly selected according to the shape, technical requirements, application and quantity of products. The process is simple, can be formed at one time, has outstanding economic effect, and particularly has outstanding process superiority for products which have complex shapes and are difficult to form and have small quantity.

The base is mounted to the surface of the wall 4 by fasteners 5 that extend through the back panel 101. The fasteners 5 here are typically expansion screws. Because the base is made of hard glass fiber reinforced plastic, the production process can easily ensure the smoothness of the surface. And the wall body 4 is difficult to ensure the smoothness of the surface, so if the wall body and the wall body are directly attached, gaps are easy to appear, and the heat insulation effect is influenced. Therefore, in actual installation, often add one deck isolation pad 6 between wall body 4 and postnotum 101, the thickness of isolation pad 6 can change under the effect of external pressure, has played the cushioning effect for fill the gap between postnotum 101 and wall body 4, strengthened the heat preservation effect. The isolation pad 6 is generally made of collodion, and is cut according to the requirement of actual size during installation.

A plurality of connecting ribs 103 are arranged at the joint of the rear back plate 101 and the first baffle plate 102 at equal intervals. The connecting rib 103 is already present at the time of base molding, and does not need to be added later, and functions to enhance the connection strength between the backboard 101 and the first baffle 102, and prevent breakage.

The heat insulating layer 2 is an integrally formed structure, the bottom of which is attached to the inner wall of the second baffle 104, and the upper of which is attached to the inner wall of the first baffle 102.

The bottom edge of the cover 105 is attached to the upper edge of the second baffle 104, and the side edge of the cover 105 is attached to the edge of the first baffle 102.

The split double-layer heat preservation stack needs to be manufactured into a mold, and two parts, namely the base and the cover body 105 which form the structural layer 1, are pressed and molded at one time by dissolving raw materials at high temperature.

The first embodiment is as follows:

the using method of the utility model is executed by referring to the following steps:

the water pipe 3 is wrapped by collodion before installation, which is beneficial to further enhancing the heat preservation effect.

When the base is installed, the base is adjusted to a proper height according to the position of a field pipeline at home, and then the base is fixed with the wall 4 through the fastener 5, generally, the installation height of the base is about 1.2m (the height of a balcony cabinet in a common resident home is 0.8m, the height of a first floor is generally 0.4m higher than the ground of the floor, and the fixed height of 1.2m is determined based on the two conditions). For a construction site with a water pipe entering the house and the height of the water pipe entering the house being lower than 1.2m, the construction site is dug under the ground in advance, and the installation of the water pipe entering the house can be met by adjusting the depth of the lower part of the base buried in the ground up and down. In fig. 3, the shaded portion is a portion buried in the ground. To the job site that the water pipe position of registering one's residence is higher than 1.2m, need build the brick platform around the water pipe, surround the water pipe, raise the mounted position equivalently, install on the brick platform bottom structural layer 1.

When this mounting step is performed, the insulating layer 2 needs to be mounted at the same time, or once the height is adjusted, the insulating layer 2 cannot be mounted in the base. After the insulating layer is installed and the height is adjusted, the structure is as shown in figure 1. After the base is installed, the joint of the base and the ground (or a brick platform) is sealed by cement and leveled.

The cover 105 is snapped onto the base, the seam between the edge of the cover 105 and the base, as indicated by the dashed line in FIG. 3. The seam location is further sealed with tape. Thereby completing the installation.

Subsequently, if the water pipe needs to be repaired, the cover body 105 is opened to be operated, and the cover body 105 is buckled again after the operation is finished and is sealed by using an adhesive tape.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
