Detailed Description
The utility model will be further described with reference to the drawings and the specific examples.
Referring to fig. 1 to 4, the utility model provides a roof structure, which comprises a plurality of fixed beams 1 arranged in parallel, wherein two steel bar frames 2 are arranged on the surface of the fixed beams 1, the top ends of the two steel bar frames 2 are connected together through a connecting rod 3, the two steel bar frames 2 are in a V shape, precast blocks 4 are arranged between the adjacent fixed beams 1, a plurality of rows of through holes 5 are arranged in the precast blocks 4, the through holes 5 penetrate through the surfaces of the precast blocks 4, hollow grooves 6 are arranged at corners of the bottoms of two sides of the precast blocks 4, the inner walls of the hollow grooves 6 are of a vertical structure, the end parts of the fixed beams 1 are fixedly connected with the precast blocks 4 through concrete layers 7, the concrete layers 7 are filled in the inner walls of the hollow grooves 6, and the surfaces of the concrete layers 7 are completely attached to the inner walls of the hollow grooves 6.
In this embodiment, but when needing to install, evenly lay a plurality of fixed crossbeams 1 on the roofing, afterwards install precast block 4 between adjacent fixed crossbeam 1, and through pouring concrete between fixed crossbeam 1 and precast block 4's dig empty slot 6 in order to form concrete layer 7, thereby with fixed crossbeam 1 and precast block 4 fixed mounting together through concrete layer 7, the stability of connection between reinforcing fixed crossbeam 1 and precast block 4, make and form a stable whole between a plurality of fixed crossbeams 1 and a plurality of precast block 4 and lay on the roofing top, construction efficiency has effectively been given up in the time of guaranteeing stable structure, and set up multirow through-hole 5 in precast block 4 inside, the through-hole 5 quantity of each row is a plurality of, thereby reduced precast block 4's weight, the roofing pressure-bearing effort has been reduced, the security of roofing has been improved, moreover through-hole 5 can make precast block 4 have certain sound insulation and heat insulation effect, thereby the thermal-acoustic insulation effect of whole structure has been improved.
