Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings and examples. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 2, the connection node of the prefabricated eave pitched roof and the prefabricated wall provided by the invention is formed by obliquely arranging eave pitched roof wallboards 2 according to the building design, and fixedly connecting the bottom surfaces of the lower parts of the eave pitched roof wallboards 2 with a vertical wall 1.
The cornice pitched roof wallboard 2 (referred to as roof wallboard for short) is a prefabricated wallboard according to the design requirement of a building, and the structure is prefabricated and maintained in a factory. Reserved joint bar holes 2-1 are arranged at the connecting positions of the cornice pitched roof wallboard 2 and the vertical wall body 1, and wallboard steel bars in the reserved joint bar holes 2-1 are normally arranged and are only of a lacking concrete structure. In this example, the reserved dowel holes 2-1 are circular holes with a diameter of 15cm, but may be made in other shapes, such as square holes, or in the shape shown in fig. 3. The distance between the reserved dowel holes 2-1 is about 1500-2000 mm.
As shown in fig. 2 and 3, bolt holes 2-2 for fixing the inclined supports are formed in the lower surfaces of the roof wall boards, and the stud holes 2-2 can be holes reserved through a mold when the wall body is prefabricated or drilled in the wall body.
The upper surface of the roof wallboard is provided with at least three lifting points, and the embodiment provided by the invention adopts four lifting points which are respectively two at the upper part and two at the lower part of the inclined wallboard. The hoisting point is a hoisting ring 2-3 pre-buried in the roof wallboard. The lifting points are matched to adjust the inclination of the roof wallboard, and the wall body is aligned and installed.
The top of the vertical wall body 1 is provided with vertical steel bars 1-1, and vertical dowel bars 1-1 are arranged corresponding to the reserved dowel holes 2-1. The vertical dowel bar 1-1 is not limited to one shown in the figure, and more vertical dowel bars can be arranged. After the roof wallboard 2 is connected with the vertical wall body 2, the vertical joint bar 1-1 can be welded with the roof wallboard reinforcing steel bar.
And the reserved dowel holes 2-1 are filled with grouting materials. After the concrete grouting material reaches the required strength, the positions of the steel bar connection are integrally fixed. A plurality of spaced apart cast-in-place regions 5 are formed in the structure.
Further, as shown in fig. 4 and 5, a groove 6 extending along the length direction of the wall body is arranged at the top of the wall body, and the cross section of the groove 6 can be square or triangular. The structure can communicate all the dowel holes to form an integrated cast-in-place area 5.
