Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled frame roof slope structure. Background Art

[0002] At present, there are two conventional methods for flat roof slope leveling. One is to construct the flat structure and level the roof by building the surface layer, which is called building slope leveling. The other is to construct the structural floor according to the structural slope leveling. Building slope leveling is to use fine stone concrete to find a certain gentle slope on the flat roof structure according to the drainage direction of the roof design, so as to guide the roof rainwater in an organized manner to the rainwater drainage system. Generally, the slope leveling gradient of the flat roof is 2%. If the building plane is large, it often causes the slope leveling layer to be too thick, resulting in excessive roof load, high structural cost, and the existing roof waterproofing performance is not good enough. Although the cast-in-place concrete structure slope leveling method can solve some of the problems caused by the above building slope leveling, it often causes certain problems to the on-site construction because the slope leveling elevation is not well controlled and the on-site beam and slab formwork is also quite troublesome.

[0022] See also Figure 1-3 , the utility model provides a technical solution: an assembled frame roof slope structure, comprising a plurality of gable side frame columns 1 and middle span frame columns 3 arranged in an array;

[0024] The same middle span frame precast beam 4 is arranged on the column cap 7 of the middle span frame column 3, the gable side frame column 1 and another adjacent middle span frame column 3, and the top of the middle span frame precast beam 4 is arranged with a middle span prestressed double T plate 6;

[0025] The same gable side frame prefabricated beam 2 is arranged on the column caps 7 of two adjacent gable side frame columns 1 located at the side, and the top of the gable side frame prefabricated beam 2 is arranged with a side span prestressed double T plate 5;

[0031] Working principle of the utility model: in order to achieve good drainage performance, reduce the surface load of the small roof, and realize the purpose of roof structure slope without formwork and support, by adjusting the top elevation of the cast-in-place frame column, the horizontal components of the roof are fully prefabricated to ensure that a natural slope is formed after the prefabricated beams and prefabricated panels are erected, and finally the structural slope is achieved. For the gable structure, since the window top fits the bottom of the prefabricated beam, the window is horizontal, so the bottom elevation of the side beam must be horizontal, but the finished surface of the roof is a slope. If the beam is prefabricated into unequal height and variable cross-section, the factory workload and the cost of prefabricated molds will increase. In order to ensure the top slope of the double T-plate of the side span, we set pads of different heights on the beam ears, and after hoisting the prefabricated double T-plate, the structural slope of the side span is achieved.

[0032] A method for slope finding of a prefabricated frame roof structure, the method is implemented in the following steps:

[0033] Step 1: Determine the top elevation of each row of columns one by one according to the slope of the roof, and pour the concrete of the frame columns;

[0034] Step 2: hoist the middle standard span prefabricated beam and the corresponding prestressed double T-plate to achieve the slope of the middle span structure;

[0035] Step 3: Set unequal height pads on the gable side beam ears according to the slope, and set up prestressed double T-plates to achieve slope adjustment of the side span structure.
