Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated buildings, in particular to a sponge city prefabricated building structure. Background Art

[0002] A sponge city refers to a city that can adapt to environmental changes and respond to natural disasters caused by rainwater, just like a sponge, and has good "elasticity". In the buildings of a sponge city, it is necessary to use plate structure assembly construction.

[0003] The existing building structure has a long construction period and produces a lot of waste, which does not meet the requirements of modern green buildings. In addition, it has poor protective effect when placed on the exterior wall, is prone to penetration during the rainy season, and has poor hydrophobic performance.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a sponge city prefabricated building structure is proposed in order to achieve a more practical purpose. Utility Model Content

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a sponge city prefabricated building structure, comprising a precast concrete panel, a waterproof panel, and a plastic drainage panel, wherein precast steel bars are arranged inside the precast concrete panel, a highly antibacterial fiber panel is laid on the outside of the precast concrete panel, and a waterproof panel is installed on the outer wall of the highly antibacterial fiber panel, an inner rectangular groove is opened in the middle of the inner side of the waterproof panel, and inner through holes are arranged on the inner wall of the inner rectangular groove, and side opening holes are opened on the outer walls of both sides of the inner rectangular groove, and a drainage slope is provided on the outer convex edge of the waterproof panel;

[0007] The prefabricated steel bar passes through the inner through hole of the waterproof plate, the interior of the waterproof plate is wrapped with a plastic drainage board, and the plastic drainage board is arranged near the end of the waterproof plate and has an inner slot, and the interior of the inner slot is wrapped with a thermal insulation lining board;

[0008] The inner wall of the precast concrete panel is provided with an inner moisture-proof panel.

[0009] Furthermore, a mounting bolt is installed inside the side opening hole, and the waterproof plate forms a detachable structure through the mounting bolt and the plastic drainage board.

[0010] Furthermore, the precast concrete panel is arranged in an L-shape as a whole, and the bottom end of the precast concrete panel and the bottom plate are interlocked.

[0011] Furthermore, the outer edge of the bottom plate is arranged in an arc shape.

[0012] Furthermore, the precast concrete panels are arranged in parallel through the high antibacterial fiberboard and the waterproof board.

[0013] Furthermore, the sizes of the waterproof board and the plastic drainage board fit together.

[0014] The utility model provides a sponge city assembled building structure, which has the following beneficial effects:

[0015] 1. This utility model uses precast concrete panels as the building base material, with high antibacterial fiberboards installed on the outside for protection and antibacterial properties, and internal moisture-proof panels installed on the inside for moisture-proof partitioning. This can greatly block the transfer of moisture to the interior, prevent the growth of internal bacteria and mold, and extend the service life of the building;

[0016] When the concrete precast panel is prefabricated, precast steel bars are arranged inside to connect with the adjacent outside, support the adjacent structure, and ensure the stability of the entire structure.

[0017] 2. In the present invention, a waterproof sheet is hung on the outermost extension end of the prefabricated steel bar. The cross-section of the waterproof sheet is a concave structure, and a plastic drain board is embedded in the groove. The plastic drain board is placed on the outside to achieve a waterproof and hydrophobic effect, and an insulation lining is provided in the inner groove of the plastic drain board to prevent the external cold air from invading the inside during hydrophobicity, thereby achieving a better thermal insulation effect.

[0018] The outer surface of the plastic drainage board is provided with a drainage slope to cope with situations where there is a large demand for drainage.

[0019] 3. In the present invention, a bottom plate is provided at the bottom extension end of the building structure, which is molded with the bottom of the precast concrete slab to ensure the firmness of the structure. The arc-shaped setting on the outside can prevent water from accumulating and facilitate drainage. BRIEF DESCRIPTION OF THE DRAWINGS
