Abstract

The utility model relates to a prefabricating reinforced concrete component. The utility model consists of reinforcements and prestressed concretes. The longitudinal reinforcements and the transverse reinforcements within the prestressed concretes are connected with each other. The two ends of the transverse reinforcements which are connected with the longitudinal reinforcements bend to a ninety angle, extending outside of the reinforcement prestressed concretes board plate, and being vertical with the board plate. A heat insulation layer and a sound insulation layer are arranged on the surface of the reinforcement prestressed concretes board plate. The two ends of the transverse reinforcements bend to a hook shape. Utilizing the component as a base plate of the multi-story roof and the building roof and throwing reinforcement prestressed concretes layer on the base plate, the utility model has the advantages of heat insulation capability, sound insulation capability, saving formwork erection timber, reducing workload of throwing prestressed concretes and being beneficial to reducing cost.

Description

A kind of energy is heat insulation, the prestressed reinforced concrete precast composite slab of sound insulation

Affiliated technical field:

The utility model relates to a kind of building prefabricated reinforced concrete board member.

Background technology:

Roofing that existing multi-story is used and floor panel, the employing prefabricated reinforced concrete porous plate that has, the employing formwork erection cast-in-situ reinforced concrete structure plate that has, the former, the overall structure performance is relatively poor, be unfavorable for antidetonation, latter's overall structure performance is better, but needs on-the-spot formwork erection and cast-in-situ reinforced concrete, and is time-consuming, cost is also higher, and both are heat insulation, soundproof effect is all undesirable.

Summary of the invention:

The purpose of this utility model is: the technical scheme that a kind of prestressed reinforced concrete precast composite slab of energy heat-insulating sound-insulating is provided, make the base plate of multi-story roofing or floor face with this plate, casting reinforced thereon again concrete or concrete layer, constitute roofing and floor panel together, can save formwork erection materials and formwork erection time, reduce the cast-in-situ reinforced concrete workload, favourable reducing cost can also heat-insulating sound-insulating.

The technical solution of the utility model is: a kind of prestressed reinforced concrete precast composite slab of energy heat-insulating sound-insulating, there is steel bar concrete to constitute, longitudinal reinforcement and transverse reinforcement are arranged in the middle of the concrete, being bent into 90 ° respectively with the transverse reinforcement two ends of longitudinal reinforcement handing-over stretches out outside the reinforced concrete slab face, vertical with this plate face, be covered with insulating or/and insulation material layer on the reinforced concrete slab face.Being bent into 90 ° stretches out the outer and transverse reinforcement two ends end vertical with this plate face of reinforced concrete slab face and is bent into respectively and colludes shape; Be bent into 90 ° of lower, outer perimeter of stretching out the outer and vertical transverse reinforcement two ends of steel bar concrete panel concrete boss vertical with this plate face and that be connected as a single entity with this plate concrete is arranged respectively with this plate face; The insulating that above-mentioned prestressed reinforced concrete precast composite slab is covered with above is or/and insulation material layer is a foamed plastics, extruded sheet, mineral wool board, the cotton plate of glass or felt.The length of this prestressed reinforced concrete precast composite slab, width and thickness are determined according to designing requirement.

Major advantage of the present utility model is: make the roofing of multi-story or the base plate of floor face with this plate, cast-in-situ reinforced concrete layer in the above again, the two combine common constitute roofing and floor panel, can save formwork erection with materials such as template about 80% and formwork erection time, reduce the cast-in-situ reinforced concrete workload, favourable reducing cost, and effect heat insulation, sound insulation is arranged, and globality, shock resistance are good, and crack resistance and bearing capacity all can meet design requirement.

Below in conjunction with drawings and Examples the utility model is further specified:

The specific embodiment:

Embodiment 1:

Fig. 1 is an embodiment of the present utility model, and it has longitudinal reinforcement 1 to join into grid with transverse reinforcement 2 (see figure 3)s, constitutes with concrete 3, and stretch out respectively outside the concrete plate at the two ends of longitudinal reinforcement, and the transverse reinforcement two ends bend 90 respectively.And it is outer vertical with this plate face to stretch out the reinforced concrete slab face, and the lower, outer perimeter at transverse reinforcement 2 two ends has concrete boss 5 (see figure 3)s vertical with this plate face and that be connected as a single entity with this plate face concrete respectively.End, transverse reinforcement two ends curves respectively colludes shape 4.Be covered with insulating 6 and insulation material layer 7 on the reinforced concrete slab face.Insulating is a mineral wool board, and puigging is a felt

Embodiment 2:

With embodiment 1 difference be: only be covered with heat insulation foam layer 6 (seeing Fig. 5, Fig. 6) above the heat insulation prestressed reinforced concrete precast composite slab of a kind of energy.

Embodiment 3:

With the difference of embodiment 1 or 2 be: only be covered with sound insulation carpet veneer 7 (seeing Fig. 7, Fig. 8) above the prestressed reinforced concrete precast composite slab of a kind of energy sound insulation.
