Problems solved by technology

[0003] When the prefabricated composite insulation panels of prefabricated walls or prefabricated roofs are currently installed with anchor bolts, there are problems that steel anchor bolts pass through the insulation layer of non-alkaline materials, which are easy to corrode, have poor durability, and increase heat transfer. And the ability of steel to resist fire is not good

Embodiment approach 1

[0015] Implementation mode one: see figure 1 , figure 2 , a structure for installing prefabricated composite thermal insulation boards with anchor bolts in this embodiment, which is composed of building main structure 1, prefabricated composite thermal insulation boards 2, and anchor bolts 20; The structure 1 is fixed, and there is a fireproof material in a certain range of the protective layer 8 at the outer end of the anchor bolt 20 or / and within a certain range on the surface, forming a structure in which the anchor bolt is used to install the prefabricated composite insulation board;

[0016] The prefabricated composite insulation board 2 includes prefabricated composite insulation boards of various structures; the prefabricated composite insulation board 2 is composed of an insulation layer 3, a protective layer 8, a mesh tensile material 5, and cement polymer mortar 4. The prefabricated composite insulation board There are steel bars or no steel bars in 2; the thermal ...

Embodiment approach 2

[0024] Implementation mode two: see figure 1 , figure 2 The difference between this embodiment and Embodiment 1 is that in this embodiment, an alkaline material 9 is injected into the casing of the anchor bolt 20, and the alkaline material 9 protects the nails or other steel connectors in the anchor bolt 20 to increase corrosion resistance. performance.

[0025] The thickness of the galvanized layer of nails is limited. When using nail-type plastic anchors, inject alkaline materials into the plastic casing, such as cement polymer mortar, and then plug the outer end with insulation materials to ensure that the durability will not last. Less than 50 years, very convenient and low price.

[0026] Explanation about the present invention:

[0027] Protective layer 8 of the present invention is modified cement mortar or modified concrete layer, including the following meanings:

[0028] 1. Including cement mortar or modified concrete modified by adding additives, fly ash, stone...

Abstract

The invention discloses a structure with a prefabricated composite insulation board mounted by anchor bolts, relates to a structure with a prefabricated composite insulation board mounted by anchor bolts in a building, and aims at the problems that steel anchor bolts of a current prefabricated composite insulation board mounted by the anchor bolts are easy to corrode while passing through an insulating layer made of non-alkaline material and thus increasing in heat transfer and the steel is poor in fire resistance. The structure comprises that, the prefabricated composite insulation board and a building major structure are fixed together by the anchor bolts, fire-proof materials are arranged within a protective layer within a certain range of the outer ends of anchor bolts and / or within a certain range of the surfaces of the anchor bolts, and thus the structure with the prefabricated composite insulation board mounted by the anchor bolts is formed. The anchor bolts for mounting the prefabricated composite insulation board is good in fireproof performance and durability.

Description

technical field [0001] The invention relates to a structure for installing prefabricated composite thermal insulation boards with anchor bolts in buildings, which is applied to installing assembled walls or assembled roofs. Background technique [0002] Prefabricated composite insulation board is a composite board commonly known as "sandwich board". [0003] When the prefabricated composite insulation panels of prefabricated walls or prefabricated roofs are currently installed with anchor bolts, there are problems that steel anchor bolts pass through the insulation layer of non-alkaline materials, which are easy to corrode, have poor durability, and increase heat transfer. And the ability of steel to resist fire is not good. [0004] In order to solve the above problems, increase the durability and safety of the building, and facilitate construction, the present invention proposes a structure for installing prefabricated composite thermal insulation boards with anchor bolts...
