Problems solved by technology

However, the existing assembled monolithic floor slabs have a small span and cannot meet the needs of large bays
The size of the lower beam of the floor is large, the indoor effect is poor, and the owner needs to install the ceiling in the later stage
At the same time, most of the floors are solid and heavy, so it is necessary to set up a separate equipment floor space, which affects the indoor net height

Embodiment Construction

[0014] Such as figure 1 and figure 2 As shown, the novel large-span hollow self-insulating floor of the present invention adds a reinforced concrete floor on the basis of the traditional well-shaped floor to form a hollow floor structure with a flat bottom. Several prefabricated floor slabs are spliced ​​and assembled through vertical and horizontal two-way concrete post-casting connection belts. A single floor slab has an integrally prefabricated top slab, bottom slab, and longitudinal and horizontal rib beams in the middle, and reserved steel bars protrude around the slab.

[0015] The prefabricated floor slab includes a top slab 1, a bottom slab 2, a number of well-shaped intersecting rib beams 3, and thermal insulation and sound insulation fillers 4; The directions are arranged at equal distances, and the thermal insulation and sound insulation fillers 4 are arranged between the rib beams 3 and fill up the gaps between the rib beams 3 .

[0016] The top slab 1, bottom s...

Abstract

The invention discloses a novel large-span assembly type hollow groined floor system which is composed of a plurality of blocks of prefabricated floors capable of being spliced and concrete post-cast strips located between adjacent prefabricated floors. Each prefabricated floor comprises a top plate, a base plate, longitudinal ribbed beams and transverse ribbed beams, wherein the longitudinal ribbed beams and the transverse ribbed beams are arranged between the top plate and the base plate. The top plates and the base plates are parallel surface plates. The novel large-span assembly type hollow groined floor system effectively solves the problem of the traditional assembly type integrated floors of small span, poor rigidity and large concrete consumption. The concrete consumption at the connection positions of all the prefabricated floors is small, template consumption is small, and the prefabricated floors are few in shapes, convenient to construct, economical and practical. The integral floor system formed by assembling all the prefabricated floors is of a hollow groined structure and has the advantages of bidirectional force transfer, large rigidity, good shock resistance and small self weight and thickness. Light thermal insulation materials are filled in the hollow positions of the floor system so that the heat retaining property of the floor system is improved. Pipes can be arranged in the floor system in a penetrating mode without additional equipment layers, and therefore space is saved and storey clear height is increased.

Description

technical field [0001] The invention belongs to the construction field, in particular to a novel large-span assembled hollow well-shaped floor. Background technique [0002] The building floor is an important horizontal structural load-bearing component, which transfers various loads acting on the floor to the vertical load-bearing components such as beams, walls, columns, and also connects the vertical load-bearing structures into a whole. [0003] At present, the common floors are mainly concrete floors, including cast-in-place concrete floors, prefabricated concrete floors and prefabricated monolithic floors. [0004] The cast-in-place concrete floor slab is a completely wet operation on site, which is difficult and requires a lot of work. At the same time, a large number of formwork turnover is required, and the cost is high. Moreover, the construction quality mainly depends on the skills of on-site workers and on-site management. If a large-area floor slab is poure...
