In order to better understand the technical content of the utility model, specific embodiments are given and described as follows in conjunction with the accompanying drawings.

Please refer to Fig. 1 and Fig. 2, the utility model proposes a wooden residential roof structure, which includes a structural layer 1, a leveling layer (not shown), a pipeline layer 3, an insulation layer 4, a waterproof layer 5, and a protection layer from bottom to top. Layer 6, tile roof layer 7, wherein the insulation layer 4 has two layers, from bottom to top are foam glass insulation board 41 and STP insulation board 42.

The structural layer 1 is mainly composed of purlins 11, rafters 12, and purlins 14 to form the main roof structure frame, and then the watchboard 13 is laid on the above components. The thickness of the watchboard 13 is 20mm, but in actual manufacturing conditions, the watchboard 13 The thickness can be made according to the requirements of the project, and the size of the rafters 12 and the purlins 14 are also determined according to the roof. Please refer to FIG. 1 , which shows eaves purlins 111 and ridge purlins 112 in the purlins 11 , and eaves purlins 1111 near the overhanging eaves.

Preferably, the structural layer 1 further includes wooden braces (not shown) and verge wood (not shown).

The leveling layer is located above the structural layer 1. The leveling layer is a wooden diagonal tie rod with a thickness of 20mm (in actual engineering manufacturing, the thickness of the wooden diagonal stay rod is determined according to the requirements of the project). The wooden diagonal stay rod is filled with cement mortar. The degree of solidity is determined by the shape of the subsequent waterproof layer 5 and heat preservation layer 4, and the ratio of cement and sand in the cement mortar is 1:3.

Above the leveling layer is the insulation layer 4, which is composed of foam glass insulation board 41 and STP insulation board 42 from bottom to top, and the pipeline layer 3 is located in the foam glass insulation board 41, please continue to refer to Figure 1, the pipeline layer 3 mainly includes a fire sprinkler pipe and a fire sprinkler head, and a spray hole 15 is opened in the purlin 11, which communicates with the pipeline layer 3, and is used for spraying from the spray hole 15 in the purlin 11 when a fire accident occurs.
