Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building floor pouring, in particular to a reinforcing bar frame structure for hollow floor pouring. BACKGROUND

[0002] In construction, the floor is an important component of the building structure, mainly used for transmitting the load between different floors to the lower structure, providing a flat horizontal surface for use and supporting other structures. The floor not only plays a key role in the function and structure of the building, but also has an impact on the safety, comfort and aesthetics of the building.

[0003] At present, the floor is usually a solid floor mainly composed of reinforced concrete (or other types of concrete), usually without hollows or cavities, and the overall structure is relatively compact, usually a cast-in-place structure, that is, the floor is cast in place with reinforcing bars and concrete at the construction site. However, due to the large weight of the solid floor, it will increase the dead weight of the building and the load on the foundation, especially in the case of large span, the solid floor may need more support and thicker structure, which increases the difficulty in design and construction. Therefore, further improvement can be made. CONTENT OF THE INVENTION

[0004] In order to reduce the dead weight of the floor and reduce the construction difficulty in the case of large span, the application provides a reinforcing bar frame structure for hollow floor pouring.

[0005] The reinforcing bar frame structure for hollow floor pouring provided by the application adopts the following technical scheme:

[0006] A reinforcing bar frame structure for hollow floor pouring, comprising a reinforcing bar frame main body and a thin-walled mold box installed inside the reinforcing bar frame main body, the thin-walled mold box is fixed by the reinforcing bar frame main body up and down, and the thin-walled mold box is arranged in a spaced arrangement; the thin-walled mold box is open at the top, and the thin-walled mold box is installed in the reinforcing bar frame main body in reverse.

[0007] By using the thin-walled mold box in the reinforcing bar frame main body, after forming, a hollow floor is formed, which can maximize the requirements of the reinforced concrete design specification in strength, deformation, displacement, etc., and realize large-span non-hidden beam, improve the use of net height of the building. Not only saves the amount of floor concrete, but also saves the materials of vertical components of the building, such as concrete walls and concrete columns, due to the reduction of the dead weight of the building.

[0008] Optionally, the thin-walled mold box is designed with a taper from top to bottom, and the top of the thin-walled mold box is integrally formed with a flange along the outer periphery thereof.

[0009] By adopting the technical scheme, in actual construction process, the thin-wall mold box can be stacked by using the taper design, which occupies small space and is conducive to civilized construction.

[0010] Optionally, the taper of the thin-wall mold box is 1° to 3°.

[0011] Optionally, a longitudinal positioning groove is integrally formed at the middle position of the bottom of the thin-wall mold box, and the longitudinal positioning groove is in the form of a straight line.

[0012] By adopting the technical scheme, in the construction process, the longitudinal steel bars in the steel bar frame body are clamped into the longitudinal positioning grooves at the bottom of the thin-wall mold box to connect the thin-wall mold boxes in the same longitudinal line, and the thin-wall mold boxes are fixed longitudinally after the steel bar binding is completed.

[0013] Optionally, a transverse positioning groove is also integrally formed at the middle position of the bottom of the thin-wall mold box, and the transverse positioning groove and the longitudinal positioning groove form a cross shape.

[0014] By adopting the technical scheme, in the construction process, a transverse auxiliary steel bar can be clamped between the transverse positioning grooves at the bottom of the adjacent two thin-wall mold boxes, and then the transverse auxiliary steel bar is fixed to the steel bar frame body to fix the thin-wall mold boxes horizontally, thereby further improving the connection strength between the thin-wall mold box and the steel bar frame body to ensure the structural strength of the floor formed after subsequent pouring.

[0015] Optionally, the longitudinal positioning groove and the transverse positioning groove divide the bottom of the thin-wall mold box into four quadrants, and protrusions are integrally formed on the four quadrants and cover the bottom surface of the thin-wall mold box.

[0016] By adopting the technical scheme, after the pouring and forming of the floor are completed, the protrusions are embedded in the poured concrete to form staggered connections with the concrete, thereby further ensuring the structural strength of the formed floor.

[0017] Optionally, the protrusions are in the form of an elliptical column, the protrusions in the same quadrant are arranged in the same direction, the protrusions in the four quadrants are mirror images along the longitudinal positioning groove and the transverse positioning groove, and the protrusions in the adjacent two quadrants are arranged at an angle.

[0018] By adopting the technical scheme, since the protrusions in the adjacent quadrants are mirror images in the four quadrants, the protrusions in different quadrants can form resistance in different directions with the poured concrete after the pouring and forming of the floor are completed, thereby better ensuring the structural strength of the formed floor.

[0019] Optionally, the thin-wall mold box is made of an environmentally friendly plastic material.

[0020] By adopting the technical scheme, since the environment-friendly plastic material is relatively environment-friendly, can be recycled and reused if damaged during construction, and theoretically achieves "zero loss" of construction, the problem of material consumption and waste is solved.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

After forming, a hollow floor slab is formed, which can maximize the requirements of reinforced concrete design specifications in strength, deformation, displacement, etc., and realize large-span non-hidden beam, improve the net height of the building. Not only saves the amount of floor concrete, but also saves the materials of vertical components of the building, such as concrete walls and concrete columns, due to the reduction of the self-weight of the building;

[0023] 2. Since the environment-friendly plastic material is relatively environment-friendly, it can be recycled and reused if damaged during construction, and theoretically achieves "zero loss" of construction, the problem of material consumption and waste is solved. At the same time, the plastic thin-walled square box has small quality and low labor intensity, improves the construction efficiency, and has excellent heat preservation and insulation performance, which can save energy and reduce emissions;

The thin-walled moulding box 2 is tapered from top to bottom, and the top of the thin-walled moulding box 2 is integrally formed with a flange 3 along its outer periphery. Preferably, the taper of the thin-walled moulding box 2 is 1° to 3°, so that the thin-walled moulding box 2 can be stacked during actual construction, occupying less space on site, which is conducive to civilized construction.

[0033] In the embodiment, the longitudinal positioning groove 4 and the transverse positioning groove 5 are integrally formed at the middle position of the bottom of the thin-walled moulding box 2, the transverse positioning groove 5 and the longitudinal positioning groove 4 form a cross shape, and the longitudinal positioning groove 4 is in the form of a straight line, and the two ends of the transverse positioning groove 5 extend through the thin-walled moulding box 2. During construction, the longitudinal reinforcement in the steel bar frame main body 1 is inserted into the longitudinal positioning groove 4 at the bottom of the thin-walled moulding box 2 to connect the thin-walled moulding boxes 2 in the same longitudinal line and fix them longitudinally. Similarly, a transverse auxiliary reinforcement can be inserted between the transverse positioning grooves 5 at the bottom of the two adjacent thin-walled moulding boxes 2, and then the transverse auxiliary reinforcement is fixed to the steel bar frame main body 1 to fix the thin-walled moulding boxes 2 transversely. After the reinforcement is bound, the thin-walled moulding boxes 2 are clamped and fixed to ensure the structural strength of the floor formed after subsequent pouring.
