Problems solved by technology

Although some structural atlases install elastic sealant at the joints, or install soft polyethylene plastic rods, but the elastic sealant and soft polyethylene plastic rods can only seal and cannot transmit internal force. If a large number of joints are installed Elastic sealant, or polyethylene plastic soft rods are also installed, and the prefabricated composite insulation boards used for the installation of the prefabricated wall or prefabricated roof cannot work together, which is not good for the force, and also affects the decoration
[0005] The above problems affect the durability of buildings and affect the process of housing industrialization
[0006] The applicant of this patent has applied for several patents on external thermal insulation walls, and now there are prefabricated walls assembled with steel wire grid cement sandwich panels, and the external plastering protective layer also has the problem of easy cracking

Abstract

The invention discloses an elastic joint structure, relates to a joint structure of prefabricated compound insulation plates, further relates to an elastic joint structure of external thermal insulation walls, and aims at the problem that the joint of the prefabricated compound insulation plate is easy to crack, and the problem that a protective layer of the external thermal insulation wall is easy to crack. The first structure is that the prefabricated compound insulation plates at the two sides of the joint are glued by a gluing material, and the gluing material on the joint can transfer internal force, so that the adjacent prefabricated compound insulation plates can form a shared stress component, and the gluing material on the joint further has the capability of being applicable to certain deformation; the second structure is that elastic cement polymer mortar is generated in a certain range of the outer end of an insulating layer of the external thermal insulation wall, a reticular tensile material is overlapped and glued with the insulating layer at the two sides of the joint by the elastic cement polymer mortar in a certain range, for the cement polymer mortar has gluing capacity and applicable deformability. According to the elastic joint structure provided by the invention, the common quality problem that the prefabricated compound insulation plates are likely to be cracked can be solved, good durability can be realized, and housing industrialization can be beneficially promoted.

Description

technical field [0001] The invention relates to an elastic joint structure used for installing prefabricated composite thermal insulation panels in buildings, and a structure for setting elastic joints in an external thermal insulation composite wall body. Background technique [0002] Prefabricated composite insulation board is a composite board commonly known as "sandwich board". [0003] Affected by drastic temperature changes between winter and summer and day and night, cracks are not suitable for sintered brick masonry, but other walls, including concrete walls, have troublesome cracks. [0004] Especially the problem that the joints of the prefabricated composite thermal insulation boards used for installing the prefabricated wall or the prefabricated roof are easy to crack is particularly prominent. Although some structural atlases install elastic sealant at the joints, or install soft polyethylene plastic rods, but the elastic sealant and soft polyethylene plastic r...
