Description

Technical Field

[0001] The utility model belongs to the technical field of precast slabs, and particularly relates to a new type of integrated thermal insulation and decoration board structure for the envelope structure of ultra-low energy consumption buildings. Background Art

[0002] Precast slabs are cast and formed in a precast factory using molds of specific unified specifications and dimensions. When needed, the formed slab bodies can be directly overlapped and fixed. Currently, hollow slabs are mainly used in construction. According to different ways of drawing holes in the slab, there are rectangular hole slabs, round hole slabs, and oval hole slabs. The rectangular hole slab can save a certain amount of concrete, but it is difficult to demold and prone to cracking on the slab surface, so it is no longer used; the oval hole and round hole increase the cross-sectional area of the slab rib, enhancing the stiffness of the slab and being beneficial for stress, but compared with each other, the round hole core pulling demolding is more convenient, so currently precast perforated slabs basically use round hole slabs. However, in the actual use process, the structural strength at the joints of the existing hollow precast slabs is insufficient, and there is a risk of misalignment during assembly connection.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long-term explorations and proposed various solutions. For example, a Chinese patent document discloses an L-shaped self-insulating shear wall precast slab for the corner of an assembled building [201911333003.6], which includes a first self-insulating precast shear wall slab and a second self-insulating precast shear wall slab. Both the first self-insulating precast shear wall slab and the second self-insulating precast shear wall slab include a thermal insulation layer and a load-bearing layer. The thermal insulation layer is located outside the load-bearing layer. The top side of the thermal insulation layer is lower than the load-bearing layer, and the left, right, and bottom sides of the thermal insulation layer are longer than the load-bearing layer. The bottom, top, left, and right sides of the load-bearing layer all extend out stirrups. The steel bars of the load-bearing layer of the first self-insulating precast shear wall slab and the stirrups extending therefrom are vertically intersected with the steel bars of the load-bearing layer of the second self-insulating precast shear wall slab and the stirrups extending therefrom, forming a square hollow column body. Vertical steel bars are located in the square hollow column body to form a steel reinforcement cage. Concrete is poured into the steel reinforcement cage. The first self-insulating precast shear wall slab and the second self-insulating precast shear wall slab are vertically fixed together to form an L-shaped integral precast wall panel.

[0004] The above solution solves the problem of the structural strength of the precast slab to a certain extent, but there are still many deficiencies in this solution, such as the problem of misalignment risk at the joints. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0023] As Figures 1-4 shown, a new type of integrated thermal insulation and decoration board structure for an ultra-low energy consumption building envelope includes a support keel 1 with a ribbed plate structure. A support grid 2 is arranged inside the support keel 1 to ensure the structural strength after casting and forming. Concrete is poured between the support keel 1 and the support grid 2 to form a precast slab 3, and precast slabs 3 of different specifications and sizes are selected according to actual needs; an exterior finish 4 made of thermal insulation material is covered on the outside of the precast slab 3. Lapping components 5 are arranged at the upper and lower ends of the precast slab 3, and splicing components 6 are arranged on both sides of the precast slab 3. The lapping components 5 and the splicing components 6 cooperate to form a building envelope with the precast slab 3; locking components are respectively equipped on the lapping components 5 and the splicing components 6 to improve their local connection stability.

[0024] Specifically, different from the conventional steel wire cage structure, in this embodiment, the support keel 1 includes an outer frame body 11 and an inner frame body 12. A support frame 13 is welded between the outer frame body 11 and the inner frame body 12. The cross-sections of the outer frame body 11 and the inner frame body 12 are T-shaped, and the cross-section of the support frame 13 is L-shaped. The support grid 2 is welded between the outer frame body 11 and the inner frame body 12. The support frame 13 is connected between the corners of the outer frame body 11 and the inner frame body 12, and there is a cavity for concrete filling between them.

[0025] Furthermore, in order to meet the window installation requirements, a window body 14 is fixedly arranged inside the inner frame body 12 by concrete pouring, and the window body 14 is assembled through other connection structures such as threaded parts.

[0026] Further, similar to the existing assembly method, the lapping component 5 in this application includes a lapping strip 51. Lapping step surfaces 52 for pressing and fixing with the precast slab 3 are respectively formed at the upper and lower ends of the lapping strip 51. The lapping strip 51 is formed by a lapping grid and concrete pouring. The outer sides of the adjacent upper and lower precast slabs 3 are flush with the outer side of the lapping strip 51, so as to ensure the flatness of the building exterior wall surface.

[0027] Even further, the locking component includes lapping grooves 53 arranged axially along the lapping step surface 52. Lapping rings 54 formed by bending steel bars are arranged in the lapping grooves 53. The precast slab 3 has lapping buckles 55 that are buckled with the lapping rings 54 one by one. The lapping grooves 53 are filled with concrete by pouring. The precast slab 3 drops vertically to the upper end of the lapping strip 51. When the lapping step surfaces 52 are in contact, the lapping rings 54 are inserted into the lapping buckles 55 to achieve lateral limitation.

[0028] In addition, the splicing component 6 is arranged at the corner of the prefabricated building. It includes a splicing column 61 arranged vertically. The splicing column 61 has a splicing plate 62 arranged vertically, and a splicing opening 63 for the precast slab 3 to slide and insert is formed on the splicing plate 62. The precast slab 3 is hoisted, and its two sides slide down vertically along the splicing opening 63 to achieve assembly and fixation.

[0029] Meanwhile, the locking component locally strengthens the splicing part, including splicing grooves 64 arranged on the inner side of the splicing opening 63 and the outer side of the precast slab 3. The splicing grooves 64 of the splicing opening 63 and the splicing grooves 64 of the precast slab 3 are arranged in a staggered manner, and the splicing grooves 64 are filled with concrete by pouring. The filled concrete seals the gap between them to ensure the subsequent waterproof treatment effect. The concrete in the staggered splicing grooves 64 condenses into a toothed structure.

[0030] Visibly, the exterior finish 4 selects a polystyrene foam board as the insulation layer. It realizes the fixation of the exterior wall by using expansion threads and fiber mesh cloth. A fiber cement is also coated on the surface of the exterior finish 4.

[0031] Obviously, the precast slab 3 is similar to the existing hollow slab, with cavities provided inside, reducing the casting cost and weight while not affecting the overall structural strength.

[0032] Preferably, expansion screw holes are reserved on the precast slab 3, and the exterior finish 4 can be fixed to the precast slab 3 through threaded parts. The reserved expansion screw holes can reduce the impact on the overall structural strength of the precast slab 3.

[0033] In summary, the principle of this embodiment is that concrete is cast between the supporting keel 1 and the supporting grid 2 to form the precast slab 3, and the structural stability of the lapping assembly 5 and the splicing assembly 6 is ensured by the locking assembly at both ends of the precast slab 3.

[0034] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
