Outer wall joint structure, outer wall and building structure

Abstract

The invention relates to an outer wall joint structure. The outer wall joint structure comprises a horizontal connecting piece and two sets of plates, and each plate comprises a plurality of prefabricated battens which are horizontally and sequentially spliced; a threaded sleeve is embedded in the bottom end of each plate of the upper side plate block and is fixedly connected with the upper node plate of the horizontal connecting piece through a bolt; threaded sleeves are embedded in the top ends of all the plates of the lower side plate block and connected with the lower joint plate of the horizontal connecting piece in a fastened mode through bolts. The invention further relates to the outer wall adopting the outer wall joint structure and a building structure comprising the outer wall. According to the outer wall joint structure, the battens with smaller areas are adopted, and the battens are respectively connected with the horizontal connecting pieces, so that the condition of larger deformation caused by bearing wind load can be avoided; the battens are connected with the horizontal connecting pieces through bolts, so that the fabricated construction of the outer wall joints can be realized, the construction efficiency can be effectively improved, and the construction cost can be saved.

Description

technical field [0001] The invention relates to an exterior wall node structure, an exterior wall using the exterior wall node structure and a building structure comprising the exterior wall. Background technique [0002] With the development of prefabricated construction technology, the application of prefabricated assembly construction for factory buildings, residential buildings and other buildings is becoming more and more extensive. At present, prefabricated wall panels with a large area are usually used in the prefabricated construction of external walls, which are prone to large deformation due to wind load and affect the safety of the building. Moreover, such prefabricated wall panels are heavy and difficult to produce and transport , storage and installation; prefabricated wall panels generally adopt the structure of profiled steel plates filled with insulation materials. Wall panels made of profiled steel plates have poor durability, which affects the service life ...

AI Technical Summary

Problems solved by technology

At present, prefabricated wall panels with a large area are usually used in the prefabricated construction of external walls, which are prone to large deformation due to wind load and affect the safety of the building. Moreover, such prefabricated wall panels are heavy and difficult to produce and transport , storage and installation; prefabricated wall panels generally adopt the structure of profiled steel plates filled with insulation materials. Wall panels made of profiled steel plates have poor durability, which affects the service life of the building, and such prefabricated wall panels generally use self-tapping screws If the profiled steel plate is fixed to the wall purlin or column, self-tapping screws will easily cause damage to the surface coating of the profiled steel plate, causing corrosion of the profiled steel plate and further affecting the service life of the wall panel; in addition, during construction of the above prefabricated wall panels, Generally, the outer profiled steel plate is sealed first, then the middle is filled with insulation materials, and the inner profiled steel plate is finally sealed. This assembly construction method has problems such as low efficiency, low degree of structural integration, and difficulty in ensuring structural strength.
