Hollow Floor Slab Introduction

Hollow floor slabs are floor slabs made by embedding core molds in cast-in-situ floor slabs.They usually arrange and cast hollow floor slabs in a certain direction. Beam, a board formed by combining a cast-in-situ hollow floor between the core mold and the core mold to form a large "I" shaped beam.

Hollow Floor Slab Features

1: Increase the headroom. It is expected that each floor is about 0.3 meters lower than the original plan.

2: The cost of construction is reduced. The construction cost is reduced by about 15%. The reinforced concrete is reduced by about 20%, the total weight is reduced, and the self-weight is reduced. about.

3: The same height, the number of layers increases.

4: Save materials. The headroom of each floor is reduced, and the corresponding water pipes, wires, stairs, interior walls, and decoration costs are reduced by about 13%.

5: The partition can be changed flexibly.This is closely connected with the large span of the hollow floor.

6: No ceiling is needed, saving ceiling decoration costs.

7: Reduce self-weight, increase safe and reliable performance.

8: shorten the construction period, sound insulation, reduce the transmission of noise.

Application range of hollow floor

1: Hollow floor slabs are used in large-span buildings.

2: Hollow floor slabs are used in large load buildings.

3: Hollow floor slabs are used in multi-story buildings.

4: Hollow floor slabs are applied to high-rise buildings.

The hollow floor slab is taken as an example of a middle school project. The building area is more than 9,000 square meters, which is a multi-layer special-shaped column frame with a total of 5 floors and a height of 18 meters. The hollow floor slab is 0.18 meters in the project, and the hollow floor slab is about 5700 degrees square meters.

Hollow floor slab construction drawing

Construction steps

1: measuring pay-off,

2 installation template,

3: The lower cushion block of the core core of the hollow floor,

4: template overline positioning,

5: beam reinforcement, plate bottom reinforcement,

6: Embedded water electrical conduit and vertical through-tube,

7: Install hollow floor inner mold,

8: Positioning of the inner mold of the hollow floor,

9: Implementation of anti-floating technology measures for hollow floors,

10: Rebar installation on the surface,

11: acceptance,

12: Building concrete,

13: Remove the mold.

Effect drawing after construction

Construction method:

1: The measurement axis position and elevation are measured from the control point to the height of the construction floor.

2: Confirm the material selection according to the hollow template support system.

3: Reinforcement and internal mold installation: firstly bundle the reinforcing steel bars, secondly place the hollow floor inner mold, and then bundle the floor steel bars again, then pad the blocks, and finally follow the set construction steps in order.

Precautions:

1: It is strictly forbidden to step on the steel bar to avoid the steel bar from changing the stress of the hollow floor.

2: It is strictly forbidden to put engineering machinery on the hollow floor, and the imitation hollow floor is damaged.

3: It is strictly forbidden to carry out construction in accordance with requirements.

4: Vibrating rods must be constructed in accordance with design requirements when vibrating.
