Problems solved by technology

[0002] The reinforced truss floor deck of the metal floor has been widely used in steel structure buildings. Because it is equipped with multiple triangular steel trusses, it has high rigidity, no support during construction, light weight, and convenient construction. It is widely used in public buildings. It has been well applied in the field of construction, but it has not been recognized and promoted in the field of concrete construction, especially residential projects. The main reason is that the properties of the metal base plate are determined. Because the bottom surface of the metal base plate is smooth, it cannot be putty directly for decoration, and the metal base plate needs to be removed. Or make a suspended ceiling for decoration, which adds additional costs

Embodiment Construction

[0029] The component of the present invention consists of prefabricated bottom plate 11, self-tapping nails or rivets 21, galvanized thin steel plate 31, lower chord longitudinal reinforcement 41, web bar wave-shaped reinforcement 51, upper chord longitudinal reinforcement 61, and upper chord transverse short reinforcement 71.

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] 1. Use a fiber cement board produced by Magnesium Construction Technology (Chongqing) Co., Ltd. that meets Class A fire protection requirements as the prefabricated bottom board 11, a large board with a size of 3000×1200×10mm.

[0032] 2. Make the in-line steel bar truss: use automated equipment to spot-weld the peaks of an upper chord longitudinal steel bar 61 and a web bar wave-shaped bar 51, and the lower bending point of the lower chord longitudinal bar 41 and the web bar wave-shaped bar 51 Welding is connected into a strai...

Abstract

The invention discloses a modular steel bar truss floor support plate. The modular steel bar truss floor support plate is characterized by comprising a prefabricated bottom plate, self-tapping screws or rivets, a galvanized steel sheet, lower chord longitudinal steel bars, upper chord longitudinal steel bars, web member wave-shaped steel bars and upper chord transverse short bars. Steel bars matched with the modular steel bar truss floor support plate are in-line single-truss steel bar trusses, the steel content is less, the bottom is flat, and putty can be directly scraped for decoration. According to the modular steel bar truss floor support plate, the cost is saved for a construction party, the purpose of fast turnover is achieved, the workload of deepening design is saved for a design party, the construction progress is accelerated for the construction party, the construction quality is better controlled, the capacity is completely released for a component production party, and therefore all parties involved in a project can obtain respective benefits.

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a modular reinforced truss floor deck. Background technique [0002] The reinforced truss floor deck of the metal floor has been widely used in steel structure buildings. Because it is equipped with multiple triangular steel trusses, it has high rigidity, no support during construction, light weight, and convenient construction. It is widely used in public buildings. It has been well applied in the field of construction, but it has not been recognized and promoted in the field of concrete construction, especially residential projects. The main reason is that the properties of the metal base plate are determined. Because the bottom surface of the metal base plate is smooth, it cannot be putty directly for decoration, and the metal base plate needs to be removed. Or make a suspended ceiling for decoration, which adds additional costs. The present invention is to in...
