Description

Technical Field

[0001] The present invention relates to the field of house construction in civil engineering. Background Art

[0002] Prefabricated buildings have the advantages of fast construction speed, low energy consumption, and low environmental pollution. They are the current development direction of construction projects. However, the integrity of prefabricated buildings is poor and is not conducive to earthquake resistance. At the same time, people are paying more and more attention to the sound insulation performance of houses. The activities of residents upstairs will affect the lives of residents downstairs, and houses with better sound insulation are needed. Therefore, a house with good sound insulation, good earthquake resistance and prefabricated construction is needed. Summary of the invention

[0003] In order to solve the problems of poor sound insulation of houses and poor integrity of prefabricated buildings, the present invention discloses a partially prefabricated soundproof house and a construction method, which has the advantages of good sound insulation effect, good earthquake resistance, low environmental pollution, etc.

[0004] The technical scheme of the partially assembled soundproof house of the present invention is: it is composed of giant columns, giant beams, cast-in-place floor slabs, cast-in-place shear walls, cast-in-place ladder beams, stair slabs, prefabricated shear walls, composite floor slabs, indoor stairs and roof slabs; the giant columns, giant beams, cast-in-place floor slabs, cast-in-place shear walls and cast-in-place ladder beams are cast-in-place reinforced concrete components, and the stair slabs, prefabricated shear walls, indoor stairs and roof slabs are prefabricated reinforced concrete components; the composite floor slabs are composed of prefabricated thin plates and cast-in-place plates, the prefabricated thin plates are prefabricated reinforced concrete components, and the cast-in-place plates are cast-in-place reinforced concrete components; the giant beams are supported on the giant columns, and the cast-in-place floor slabs are supported on the giant beams to form a giant frame, and the giant frame can be built in multiple layers; each layer of the cast-in-place floor slab of the giant frame has three layers of internal houses, the three layers of internal houses are one household, and only the first layer of the internal house is provided with an entrance door, and the internal house has a three-story atrium; the internal house The load-bearing components of the house are prefabricated shear walls and composite floor slabs. The prefabricated shear walls enclose the rooms. The two sides of the prefabricated shear walls on the four outer sides of the internal house are connected to the giant columns. The prefabricated shear walls on the first floor of the internal house are fixed on the giant beams and the cast-in-place floor slabs. The composite floor slabs are supported on the prefabricated shear walls. The indoor stairs are overlapped on the convex beams of the prefabricated shear walls. The composite floor slabs on the top floor of the internal house do not touch the giant beams. The roof slab is located between the composite floor slabs on the top floor of the internal house and the giant beams. The giant columns are of two types: L-shaped and straight-shaped. There are holes on the straight-shaped giant columns. A part of the cast-in-place shear walls encloses a rectangle to form an elevator room. A part of the cast-in-place shear walls encloses a trough to form a public staircase with the straight-shaped giant columns. The cast-in-place shear walls only have holes in the cast-in-place floor slabs as a passage for people to pass through. The cast-in-place ladder beams are located in the public staircase, with both ends supported on the cast-in-place shear walls. The two ends of the stair slabs are overlapped on the cast-in-place ladder beams.

[0005] Since the cast-in-place floor slab does not contact the top laminated floor of the internal house below it, the sound of the residents' activities on the upper floors will not be transmitted to the lower floors, and the sound insulation performance is good; the same three-story internal house is built in each giant frame, the internal house is a prefabricated structure, and the internal house only bears its own weight, so the prefabricated shear wall is small in size and simple in specifications, which is easy to construct; the load-bearing system of the entire building is a giant frame composed of giant columns and giant beams, which is a cast-in-place structure with good seismic resistance and integrity. The giant frame formed by giant columns and giant beams can be built in multiple layers to form high-rise buildings, with high land utilization rate. It can be built in the urban area of ​​the city, with convenient transportation, complete supporting facilities, and convenient life. The internal house only bears its own weight, and the structural components and room layout are flexible. It has a large space atrium and indoor stairs. The house is comfortable and similar to a single-family house.

[0006] The construction method of the partially assembled soundproof house of the present invention is as follows: processing stair slabs, prefabricated shear walls, prefabricated thin plates, indoor stairs and roof slabs in a factory; constructing giant columns, cast-in-place shear walls and cast-in-place ladder beams on site, and casting the giant columns and cast-in-place shear walls to the bottom of the giant beams; hoisting the prefabricated shear walls, indoor stairs and prefabricated thin plates of the composite floor slabs of the first floor of the internal house, tying the steel bars of the cast-in-place slabs of the composite floor slabs and pouring concrete to complete the construction of the first floor of the internal house, and then gradually constructing upward to the third floor of the internal house; constructing the nodes of the giant columns and giant beams, giant beams, cast-in-place floor slabs, cast-in-place shear walls and cast-in-place ladder beams on site; hoisting the stair slabs, overlapping the stair slabs on the cast-in-place ladder beams, hoisting the roof slabs, and fixing the roof slabs on the composite floor slabs and giant beams on the top floor of the internal house; repeating the above steps to complete the construction of the upper floors, and the cast-in-place floor slabs on the top floor do not have openings.

[0007] The partially assembled soundproof house of the present invention adopts a giant frame structure, and three layers of internal houses are built in each giant frame. The three layers of internal houses are for one household. The cast-in-place floor of the giant frame is not connected to the top layer of the internal house below it, thereby avoiding the influence of the upstairs noise on the downstairs. The internal house adopts an assembled structure, which is energy-saving, environmentally friendly, and has a fast construction speed. The construction method can ensure that the cast-in-place construction and the assembly construction are carried out reasonably and orderly. The present invention can solve the problems of poor sound insulation of houses and poor integrity of assembled buildings, and ensure the safety and comfort of houses.
