The prefabricated construction method of external wall structure prefabricated section and external wall structure
Technical field
The invention belongs to the building structural element technical field, be specifically related to a kind of external wall structure prefabricated section and adopt this external wall structure prefabricated section to build the prefabricated construction method of external wall structure.
Background technology
In the tunnel construction, it is the difficult problem that the highway landscape moulding faces that the tunnel headwall is processed always, and present general employing application metope, GRC mould the methods such as stone moulding and subsides ornament face the tunnel headwall is carried out sight sculpt, and headwall profile structure is carried out outside aesthetics optimization.Wherein, because GRC moulds stone and paste to hang the materials ' durability of finish material better, uses comparatively extensively, but the method for pasting the extension finish material is easily fallen piece, driving is caused potential safety hazard, so its application is restricted.
Can satisfy to a certain extent the construction of tunnel headwall and other external wall structures although present employing GRC moulds the methods such as stone, also have the following disadvantages:
1) construction inconvenience: the aesthetics for external wall structure needs, existing sheet material shape and structure for building external wall structure is irregular, need the professional to instruct the assembly unit that just can complete each piece sheet material in building course, cause construction construction inconvenience and efficiency of construction low;
2) inconvenient maintenance: because the shape and structure of sheet material is irregular, after wherein a sheet material damages, can't replaces with other sheet materials immediately and repair, must again make the replacement sheet material identical with damaging the sheet material shape and structure, cause maintenance cost high, length consuming time.
In view of this, the present invention is intended to explore a kind of external wall structure prefabricated section and the prefabricated construction method of external wall structure, and this external wall structure prefabricated section can satisfy the profile structure of external wall structure and decorate, and simple in structure, constructability and maintenance.
