Description
Technical Field
The utility model relates to a building structure material, in particular to a precast light concrete slab structure.
Background
Precast Lightweight Concrete Panels (ALC Panels for short) are Lightweight mortar precast products which are full of small uniform bubbles. The main raw materials are cement, quartz sand and lime, the mixture is mixed with water, the lining rib arrangement is foamed and condensed, then the cut plate is cut into required size, and then the plate is put into a high-temperature steam chamber for curing for 10 hours to form a plate with firm quality. The ALC board is a precast light concrete product produced by a factory, can be matched with metal accessories, is assembled and installed on a construction site by adopting a dry construction method, can be applied to an outer wall, an inner wall, a floor and a roof board of a building, and is widely used in building structural materials in China, and the ALC board has the advantages of light weight (1/5 of concrete), excellent heat conductivity (1/10 of concrete), sound insulation, heat insulation, fire resistance, non-combustion and the like, and is an effective building material matched with an energy policy.
However, the ALC board has the above-mentioned advantages, but has the disadvantages of easy cracking, lacking of edge break angle, large water absorption (not waterproof), etc., which causes great troubles in use, and thus, improvement is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a precast lightweight concrete slab structure which not only has the advantages of light weight, sound insulation, heat insulation, fire resistance, non-combustion and the like, but also has the advantages of difficult cracking, difficult edge and corner missing, excellent waterproofness and the like.
In order to achieve the above object, the precast lightweight concrete slab structure provided by the present invention comprises a rectangular slab of precast lightweight concrete, wherein a honeycomb anti-crack mesh layer is arranged at the periphery of the slab and covers each edge, corner and edge, and the honeycomb anti-crack mesh layer is woven by a plurality of high-tenacity fiber yarns; and the fiber waterproof coating is coated on the honeycomb anti-cracking net layer, so that the honeycomb anti-cracking net layer is fixed on the plate body, and the fiber waterproof coating is added with alkali-resistant anti-cracking fibers.
Further, the plate body further comprises a wall material which is arranged on the front surface and the rear surface of the plate body.
Furthermore, a groove is formed in the bottom surface of the board body, a rib is correspondingly formed in the top surface of the board body, and the honeycomb anti-cracking net layer also covers the groove and the rib.

Detailed Description
Referring to fig. 1 and 2, a structure of a precast lightweight concrete slab according to a preferred embodiment of the present invention includes:
a plate body 10, the plate body 10 is made of precast Lightweight Concrete (ALC) plate, and is rectangular, the bottom surface of the plate body 10 is provided with a groove 11, and the top surface of the plate body 10 is correspondingly provided with a convex rib 12.
A honeycomb anti-crack net layer 20, which is laid on the peripheral surface of the board body 10 and covers each edge, corner and side of the board body 10, wherein the honeycomb anti-crack net layer 20 is woven by a plurality of high-tenacity fiber yarns.
A fiber waterproof coating 30, which is coated on the honeycomb anti-crack net layer 20 corresponding to the honeycomb anti-crack net layer 20, wherein the fiber waterproof coating 30 is prepared by copolymerizing water-based polymer emulsion with silicon crystal aggregate powder, and is added with alkali-resistant anti-crack fibers 31. Therefore, the precast lightweight concrete board not only has the advantages of light weight, sound insulation, heat insulation, fire resistance, non-combustion and the like, but also has the advantages of difficult cracking, difficult edge and corner missing, excellent waterproofness and the like.
Please refer to fig. 3 and 4, which illustrate another preferred embodiment of a precast lightweight concrete slab structure according to the present invention, wherein a wall material 40 is further disposed on each of the front and rear surfaces of the slab body 10, the wall material 40 is formed by mixing talc powder, sierozem powder, white cement, glue powder, an anti-cracking additive, a reinforcing agent, and blue crystal liquid, and has the functions of crack resistance, reinforcement, water resistance, moisture resistance, ultraviolet resistance, heat insulation, heat preservation, alkali resistance, and decoration, and the multifunctional wall material 40 replaces the traditional putty powder and is coated with decorative materials (such as stone paint and paint), and has the disadvantages of multiple processes, high construction cost, poor quality, and short service life.
The features of the utility model and their expected effects are further set forth below:
1. the precast lightweight concrete plate structure not only can keep the advantages of light weight, sound insulation, heat insulation, fire resistance, non-combustion and the like, but also has the advantages of difficult cracking, difficult edge and corner missing, excellent waterproofness and the like.
2. The precast lightweight concrete slab structure is easy to construct and has the functions of crack resistance, reinforcement, water resistance, moisture resistance, ultraviolet resistance, heat insulation, heat preservation, alkali resistance, decoration and the like.
In summary, the present invention has been made in the same manner as above, and the present invention has been made in accordance with the present invention, and the present invention provides a novel and useful method for making a new and useful structure.
