Problems solved by technology
[0002] Airtight civil air defense walls have higher airtight requirements than ordinary shear walls, and cast-in-place civil air defense walls often have pre-embedded casings (such as airtight measuring pipes in protective passages) missing or casings passing through the wall during construction. Problems such as non-standard protection and airtight practices; and problems such as the use of PVC sleeves and screws to pull the formwork in the field formwork engineering, resulting in multiple post-openings in the air-defense airtight wall, which cannot meet the requirements of the civil air defense code. Pre-buried in civil construction requirements in place, the airtightness of the wall is reduced

Embodiment
[0025] Please refer to the accompanying drawings of the description. In the embodiment of the present invention, an assembled integral steel plate concrete civil airtight wall includes a prefabricated double-blank steel plate wall structure 1 and a cast-in-place concrete laminated solid core 2. The prefabricated double-blank steel plate The wall structure 1 includes an outer steel plate wall skin 101, an inner steel plate wall skin 102 and a reinforcing rib 103, the reinforcing rib 103 is evenly arranged between the outer steel plate wall skin 101 and the inner steel plate wall skin 102, and the outer steel plate wall skin The skin 101 and the inner steel plate wall skin 102 are connected by reinforcing ribs 103; there is a hollow reserved cavity 104 between the outer steel plate wall skin 101, the inner steel plate wall skin 102 and the reinforcing rib 103; the reserved cavity In 104, the cast-in-place concrete solid core 2 is poured in the later stage, and the reinforcing rib...

The invention discloses an assembled integral type steel plate concrete civil air defense closed wall. The closed wall comprises a prefabricated double-blank steel plate wall structure and a cast-in-place concrete overlapped solid core, the prefabricated double-blank steel plate wall structure comprises an outer side steel plate wall surface, an inner side steel plate wall surface and reinforcing ribs, the reinforcing ribs are uniformly arranged between the outer side steel plate wall surface and the inner side steel plate wall surface, and the outer side steel plate wall surface and the inner side steel plate wall surface are connected through the reinforcing ribs. The prefabricated double-blank steel plate wall structure has the advantages that the precision is high, formwork erecting is not needed on a construction site, a reserved cavity is completed through one-time grouting, the integrity of a wall body is good, and potential quality hazards of the wall body caused by various construction measures are avoided; the prefabricated double-blank steel plate wall structure is of a large-cavity structure, less in weight and convenient to install and transport; and the whole section of the prefabricated double-blank steel plate wall structure is free of formworks, and construction is convenient.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled integral steel plate concrete civil airtight wall. Background technique [0002] Airtight civil air defense walls have higher airtight requirements than ordinary shear walls, and cast-in-place civil air defense walls often have pre-embedded casings (such as airtight measuring pipes in protective passages) missing or casings passing through the wall during construction. Problems such as non-standard protection and airtight practices; and problems such as the use of PVC sleeves and screws to pull the formwork in the field formwork engineering, resulting in multiple post-openings in the air-defense airtight wall, which cannot meet the requirements of the civil air defense code. If the requirements are in place, the airtightness of the wall will be reduced. Contents of the invention [0003] In order to achieve the above object, the present invention ...
