Problems solved by technology
The use of composite structures takes advantage of the advantages of steel and concrete, and has good mechanical performance and certain economic benefits, but there are also disadvantages of cast-in-place slabs such as heavy workload, long construction time, and high floors.
[0004]
And, under the geological conditions where the soil layer is sandy soil layer and the rock layer is deep, the construction pile must be driven very deep, requiring a large amount of earth and rock engineering, which has a great impact on the surrounding buildings and ground, and the efficiency is also low , cost more

Embodiment 2
[0081] refer to Figure 4-8 As shown, this embodiment discloses a building, which includes: a steel pipe pile 100 for building support; the steel pipe pile 100 includes: a hollow steel pipe 110 and a rotatable stiffener assembly 120;
[0082] The rotatable stiffener assembly 120 includes: a support 122 and a rib 121; the support 122 is an arc-shaped plate, and the rib 121 is fixed on the outer surface of the support 122;
[0083] The pipe wall of the hollow steel pipe 110 is provided with a pre-opening hole 111;
[0084] The rotatable stiffener assembly 120 is rotatably inserted into the hollow steel pipe 110; the rotatable stiffener assembly 120 is forced to rotate by external force, and the rib plate 121 protrudes from the pre-opened hole 111 by the Referring to the hollow steel pipe 110, the outer surface of the support member 122 abuts against the inner wall of the hollow steel pipe 110.
[0085] The construction of the steel pipe pile 100 is relatively simple, and has t...

The present invention provides a Wang-shaped steel beam supporting prefabricated slab assembled composite floor and its building, wherein the assembled composite floor includes: Wang-shaped steel beam and prefabricated floor; the Wang-shaped steel beam includes an upper flange, a middle flange, a lower flange and a web; the middle flange is wider than the upper flange; the end of the prefabricated floor is lapped on the middle flange; The surface is flush. In the present invention, the prefabricated floor slab is placed on the upper surface of the middle flange on both sides of the Wang-shaped steel beam, and the upper flange of the steel beam is at the same height as the upper surface of the prefabricated floor slab, which reduces the overall height of the floor, thereby reducing the height of the building floor; on the other hand , The use of prefabricated floor slabs avoids a lot of work such as on-site formwork, steel bar binding and concrete pouring, and has the advantages of fast construction speed, high degree of industrialization, energy saving and environmental protection.
Description
technical field [0001] The present invention relates to the technical field of building structures, and also relates to the drilling of soil layers or rock layers, and the construction of piles while reducing the damage to surrounding buildings and ground, in particular to an assembly of king-shaped steel beams supporting prefabricated slabs Type composite floor and its buildings. Background technique [0002] At present, most of the construction methods of buildings are still mainly cast-in-place. The cast-in-place integral floor is widely used because of its good integrity and strong seismic performance. However, there are many on-site operations, heavy weight, complex procedures, long construction period, and a large number of formwork is required on site. The proportion and scale of prefabricated buildings are low and do not meet the relevant requirements for the development of green buildings. The prefabricated steel structure building has the unique advantages of gre...
