Problems solved by technology

Whether it is an open beam or a hidden beam, it is necessary to bind the stirrups on site before pouring concrete (concrete) during construction. The process is complicated, the construction period is long, and the weight of the floor or slab is increased, which also increases the construction cost.

Embodiment approach 1

[0036] Implementation Mode 1: see image 3 , the supporting column unit 2a includes a column body 21a and a column cap 22a, the column cap 22a is arranged on the upper end of the column body 21a, the upper end of the column cap 22a is arranged on the lower end surface of the floor 1, and the column cap The lower end of 22a is connected to the upper end of the column 21a, and the lower end of the column 21a is set on the ground. The horizontal cross-sectional area of ​​the column cap 22a is larger than the horizontal cross-sectional area of ​​the column body 21a. The floor 1 transmits the force received in the longitudinal direction to the column cap 22a, and the column cap 22a then indirectly transmits the force to the column body 21a, and the column body 21a finally transmits the force to the ground, and the supporting column unit 2a plays a role in supporting the floor 1 role. The column cap 22a concentrates and transmits the force received by the large area on the upper p...

Embodiment approach 2

[0039] Implementation mode two: see Figure 4 , the supporting column unit 2b includes a column body 21b and a column cap 22b, the column cap 22b is funnel-shaped with a large upper end and a small lower end, and the upper end surface of the column cap 22b is connected to the lower end surface of the floor 1, The lower end surface of the column cap 22b is connected to the upper end of the column body 21b, and the horizontal cross-sectional area of ​​the column cap 22b is larger than that of the column body 21b. The funnel-shaped column cap 22b not only meets the stress requirements of the building, but also has a beautiful appearance.

[0040] In order to improve the effect of force transmission, the side surface of the lower end of the column cap 22b and the side surface of the upper end of the column body 21b make a smooth transition. The smooth transition structure also makes the support column unit 2b more beautiful.

Embodiment approach 3

[0041] Embodiment 3 (not shown in the figure): the supporting column unit 2 includes a column, the upper end of the column is set on the lower end surface of the floor 1 , and the lower end of the column is set on the ground. In fact, the column cap is not necessary for the support column unit 2, and the support column unit 2 can also play the role of supporting the floor 1 by only including columns, as long as the size meets the requirements of construction mechanics.

[0042]In the embodiment of the present invention, the mandrel 13 can be a hollow tube, an inflatable mandrel or a wooden mandrel, and the inflatable mandrel is an air bag of rubber material. Mandrel 13 also can select the mandrel of other materials, for example bamboo mould. Its density is smaller than that of concrete, which can ensure that the weight of the floor 1 is sufficiently light. If the inflatable mandrel is selected, a through hole for extracting the air bag of the mandrel can also be reserved on t...

Abstract

The invention provides a hollow beamless floor system structure. The hollow beamless floor system structure comprises a floor system and a plurality of support column units. The upper end of each support column unit is arranged on the lower end face of the floor system. The lower end of the each support column unit is arranged on the ground. The floor system comprises a solidified concrete, a plurality of reinforcing steel bars and a plurality of core molds are embedded in the concrete. The reinforcing steel bars are arranged in a criss-cross mode to form a plurality of latticed reinforcement cages. The core molds are located in the reinforcement cages. The hollow beamless floor system structure is light in weight and can be safe to use without any beams and applicable to a floor slab. The invention further provides a construction method of the hollow beamless floor system structure. The method is used for building the hollow beamless floor system structure and includes the steps of arranging the support column units on the ground, erecting frameworks at the upper ends of the support column units, arranging the reinforcement cages on the frameworks, fixing the core molds in the reinforcement cages, pouring liquid-state concrete on the frameworks so that the liquid-state concrete can flow into the reinforcement cages and completely flood the core molds and finally forming the hollow beamless floor system structure after the liquid-state concrete is solidified.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a beamless hollow floor structure and a construction method thereof. Background technique [0002] In order to ensure the safe use of buildings and buildings, existing floors or slabs need to be provided with beams to improve their shear strength. Beams include exposed beams and hidden beams. The exposed beams refer to the beams exposed on the lower end of the floor or the floor, and the hidden beams refer to the beams embedded in the floor or the floor. Regardless of whether it is an open beam or a hidden beam, it is necessary to tie the stirrups on site and then pour concrete (concrete) during construction. The process is complicated, the construction period is long, and the weight of the floor or floor slab is increased, which also increases the construction cost. Also, see figure 1 , for the exposed beam 2', the exposed beam 2' is set on the lower end of the f...
