Embodiment 1

[0045] like Figures 1 to 3 As shown, it is a prefabricated floor slab small-slope roof structure of the present invention, which includes a frame beam 1 and several prefabricated floor slabs 2 laid on the frame beam 1. It should be noted that the cross section of the frame beam 1 is generally rectangular or T In the assembled monolithic frame structure, the frame beam 1 is often made into a rectangular section, the prefabricated floor slabs 2 are continuously arranged in a row along the slope direction of the sloping roof, and several rows of prefabricated floor slabs 2 are arranged at intervals perpendicular to the slope direction. It is understood that a plurality of prefabricated floor slabs 2 are laid on a plurality of frame beams 1 arranged at intervals in a matrix manner, and the prefabricated floor slabs 2 include a slab main body, and the front and rear ends of the slab main body both extend downward into a longitudinal section 21 and then face the The front and rear ...

Embodiment 2

[0061] like Figure 4 As shown in the figure, the difference between the prefabricated floor slab small-slope roof structure of the present embodiment and the embodiment 1 is that the prefabricated floor slab 2 and the frame beam 1 are fixed in different ways, no neoprene pad is provided, and the top surface of the frame beam 1 is anchored into the Insert bar 75, the anchored bar 75 is a closed stirrup, and the closed stirrup is formed by cross-connecting two U-shaped stirrups, one of which is embedded in the top of the frame beam 1, with a diameter of 12 mm and a diameter of 12 mm. The stirrups with a spacing of 200mm are bent, and the inner side is bound with a plurality of HRB600 third steel bars 83 with a diameter of 12mm; the lower part of another U-shaped stirrup is located in the frame beam 1, and the upper part extends out of the frame beam 1 Entering the concrete part, it is also formed by bending stirrups with a diameter of 12mm and a spacing of 200mm, and the inner ...

Embodiment 3

[0065] like Figure 5 As shown, the difference between the small-slope roof structure of the prefabricated floor slab in this embodiment and Embodiment 2 is that the frame beam 1 of this embodiment is a single-sided frame beam, and the beam gluten 73 and the beam bottom rib 74 of the prefabricated floor slab 2 pass through the The welded connection bars 71 connect the support bars 76 arranged along the length direction, the length of the support bars 76 is preferably 400 mm, and the support bars 76 are located in the closed part of the insert bars.

[0066] Insert bars 75 are anchored on the top surface of the frame beam 1. The anchor bars 75 are closed stirrups. The closed stirrups are formed by cross-connecting two U-shaped stirrups, and one of the U-shaped stirrups is embedded in the frame. The inner top of beam 1 is formed by bending stirrups with a diameter of 12mm and a spacing of 200mm, and the inner side is bound with a plurality of fifth steel bars 85 with a diameter ...

Abstract

The invention discloses a prefabricated floor slab small-slope roof structure, a construction method and prefabricated floor slabs, the prefabricated floor slab small-slope roof structure comprises a frame beam and a plurality of prefabricated floor slabs laid on the frame beam, the prefabricated floor slabs are continuously arranged in rows in the slope direction of a slope roof, the multiple rows of prefabricated floor slabs are arranged at intervals in the direction perpendicular to the slope, and each prefabricated floor slab comprises a slab body; the front end and the tail end of each slab body extend downwards to form longitudinal sections and then are bent outwards to form butt joint parts, the butt joint parts of every two adjacent prefabricated floor slabs in each row are oppositely combined to form a filling area defined by the longitudinal sections and the butt joint parts, and gaps are formed between the prefabricated floor slabs and the frame beams. Gaps communicated with the gaps and the filling areas are formed in the two sides of each row of prefabricated floor slabs, and the gaps, the gaps and the filling areas are filled with concrete, so that all the prefabricated floor slabs and the frame beam are fixedly connected through the concrete, and every two adjacent prefabricated floor slabs are fixedly connected through the concrete. The device is simple and compact in structure, meets the safety requirement, is simple and convenient to assemble on site, reduces the construction difficulty and labor intensity, and improves the working efficiency.

Description

technical field [0001] The invention relates to a prefabricated floor slab small-slope roof structure, also relates to a construction method of the prefabricated slab low-slope roof structure, and also relates to a prefabricated slab used in the prefabricated slab low-slope roof structure. Background technique [0002] With the development of the construction industry, people's life needs are diversified. In recent years, many novel and unique sloping roof structures have been presented in architectural design. [0003] The construction method of the traditional sloping roof structure is to first lay the slope bottom formwork on the frame beam or set a layer of steel mesh on the frame beam, and then form it by pouring and shooting. Therefore, this construction method has the following defects: [0004] (1) This construction method is only suitable for sloping roofs with lower slopes. [0005] (2) It is easy to cause concrete slippage or segregation during the construction p...
