Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building reconstruction, and more specifically, to a low vertical height floor sandwich. Background Art
[0002] A mezzanine is a floor located between two natural floors and refers to a partial level of the interior space of a house. For example, a house looks like a two-story building from the outside, but partially has three floors from the inside. The middle floor of the three floors is called a mezzanine. With the popularity of small commercial apartment buildings and office buildings, developers tend to choose to add mezzanines to existing floors in pursuit of high cost-effectiveness and flexible use of building space, which has led to a sharp increase in the design and construction of mezzanines.
[0003] The traditional mezzanine method is to cast in-situ reinforced concrete floor slabs, and the corrugated steel plate is arranged above the H-shaped steel beam. The Chinese patent with publication number CN208293861U discloses a low vertical height floor mezzanine, including: H-shaped steel beam, corrugated steel plate, reinforced concrete; the two ends of the H-shaped steel beam are connected and fixed to the original building wall, and are placed in an "I" shape; the corrugated steel plate is placed on the lower flange of the H-shaped steel beam, and the side wall of the corrugated steel plate is welded to the belly wall of the H-shaped steel beam; the reinforced concrete is cast above the corrugated steel plate.
[0004] With respect to the above-mentioned public technology, the side wall of the corrugated steel plate is welded to the web wall of the H-shaped steel beam. During pouring, the top surface of the corrugated steel plate will bear the gravity of the concrete pouring and the impact force during vibration. The supporting strength of the welds between the H-shaped steel beam and the corrugated steel plate is low, and the H-shaped steel beam and the corrugated steel plate are prone to breakage and separation.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0009] The utility model is further configured as follows: the horizontal steel bars and the vertical steel bars are both threaded steel bars, and the vertical steel bars and the horizontal steel bars are vertically arranged, and the bottom ends of the vertical steel bars and the top surfaces of the corrugated steel plates are fully welded.
[0010] The utility model is further configured as follows: the corrugated steel plate is configured in a corrugated structure, and a decorative plate is installed on the bottom surface of the corrugated steel plate.
[0011] The utility model is further configured as follows: there are multiple groups of T-shaped steel frames, and the gap between two adjacent groups of T-shaped steel frames is eighty centimeters.
[0012] The utility model is further configured as follows: during installation, mounting bolts are pre-embedded in the interior of the building wall for rotation, and the mounting threads and the anchor holes on the end faces of the T-shaped steel frame are correspondingly arranged.
[0013] In summary, the utility model has the following beneficial effects:
[0014] By inserting the cross-frame steel bars into the inside of the T-shaped steel frame, multiple groups of T-shaped steel frames can be assembled, and a metal mesh is installed between two adjacent groups of T-shaped steel frames.

The cross-frame steel bars can be installed through the through holes on the surface of the T-shaped steel frame. BRIEF DESCRIPTION OF THE DRAWINGS
