However, the laminated panels of the prior art are limited to some buildings with relatively small spans. For example, in some large-span structures such as industrial plants, this conventional laminated panel is not suitable, and the country is promoting prefabricated buildings in Dali. In the future development process, more and more such large-span structures will be built with prefabricated technology.

Embodiment 1
[0030] Such as figure 1 As shown, an inverted U-shaped prestressed laminated floor slab includes a prestressed laminated slab 1, the prestressed laminated slab 1 is an inverted U-shaped structure, two ends of the prestressed laminated slab 1 are provided with feet 3, and the prestressed laminated slab 1 has two The legs 3 at the end are provided with prestressed steel bars 2; the outer bottoms of the legs 3 at both ends are provided with protruding slope feet 4.
[0031] The installation method of the inverted U-shaped prestressed laminated floor of this embodiment may include the following steps:
[0032] After the prestressed laminated plate 1 is produced according to the modulus width and the required length, it is transported to the site;
[0033] Hoist the prestressed laminated slabs 1 sequentially from one side;
[0034] After the entire layer of prestressed laminated slab 1 is hoisted and fixedly connected, the cast-in-place layer reinforcement is bound, and then the ...
Embodiment 2
[0036] Such as figure 2 As shown, for the inverted U-shaped prestressed laminated floor slab in Embodiment 1, the number of prestressed laminated slabs 1 may be at least two, and adjacent prestressed laminated slabs 1 are connected to each other.
[0037] Furthermore, the legs 3 of adjacent prestressed laminated panels 1 are fixed by clamps 5 .
[0038] Then, the installation method of the inverted U-shaped prestressed laminated floor slab in Embodiment 1 can be further, when the prestressed laminated slab 1 is hoisted sequentially from one side, the legs 3 of two adjacent laminated slabs are fixed by the clamp 5 fixed.
Embodiment 3
[0040] Such as Figure 3 to Figure 5 As shown, the inverted U-shaped prestressed laminated floor slab in embodiment 1 or embodiment 2 may further have an inverted U-shaped structure for the prestressed steel bar 2 .
[0041] Furthermore, a notch structure 6 is provided at the bottom of the slope foot 4 .
[0042] Furthermore, the building weather-resistant sealant layer 7 is sealed at the missing corner structure 6 .
[0043] Furthermore, the fixture 5 is an inverted double T-shaped structure, two vertical steel plates 8 are connected to the upper surface of the bottom steel plate 9, the outer side of the vertical steel plate 8 is connected to the stiffener plate 10, and the middle of the vertical steel plate 8 is connected to the fastening bolt 11.
[0044] Then the installation method of the inverted U-shaped prestressed laminated floor slab in embodiment 1 or embodiment 2 can be further, after the cast-in-place concrete is poured, after the concrete curing period has passe...

Abstract
The invention discloses an inverted-U-shaped prestressed composite floor slab and a mounting method thereof. A prestressed composite slab of the inverted-U-shaped prestressed composite floor slab is of an inverted-U-shaped structure, supporting feet are arranged at the two ends of the prestressed composite slab, and prestressed steel bars are arranged on the supporting feet at the two ends of the prestressed composite slab; and protruding slope toes are arranged at the bottoms of the outer sides of the supporting feet at the two ends. According to the inverted-U-shaped prestressed composite floor slab and the mounting method thereof, application of the prestressed composite slab in a large-span structure is achieved through the supporting feet on the two sides of the prestressed composite slab and the prestressed steel bars in the supporting feet, meanwhile, the size of the prestressed composite slab can be modularized, the production efficiency and the turnover rate of a mold can be improved advantageously, and the production cost can be reduced; and the prestressed composite slab of the inverted-U-shaped prestressed composite floor slab is of the inverted-U-shaped structure, laying and mounting of equipment pipelines can be conducted through a U-shaped space at the bottom, the situation that the clear floor height of a building is affected is avoided through hidden pipeline mounting, and the space utilization rate of the building can be increased.
Description
technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to an inverted U-shaped prestressed laminated floor slab and an installation method thereof. Background technique [0002] Prefabricated buildings have developed rapidly in recent years, and construction industries everywhere are undergoing transformation and upgrading, and prefabricated buildings are the main development direction. At present, the laminated slab is the most widely used component type in prefabricated buildings, and it can be used in a variety of buildings, such as high-rise residential shear wall structures, ordinary frame structures, and so on. However, the laminated panels of the prior art are limited to some buildings with relatively small spans. For example, in some large-span structures such as industrial plants, this conventional laminated panel is not suitable, and the country is promoting prefabricated buildings in Dali. In the ...
