Problems solved by technology

The traditional method of slab thickness control in the pouring process is to use graduated steel bars to insert into the concrete floor slab to measure the slab thickness, which leads to poor construction accuracy
However, there is no standard for the upper part of the slab negative rib protective layer, and the thickness can only be estimated by the on-site construction personnel. In this way, the thickness of the construction protective layer cannot be effectively guaranteed and it is easy to cause waste of cost.
[0003] Therefore, there are above-mentioned inconveniences and problems in the protective layer control and the floor thickness control mode of the known floor negative reinforcement.

Embodiment 1

[0023] The multifunctional stirrup used for controlling the thickness of steel bar protection layer and floor slab of the present invention comprises two J-shaped bars and a horizontal bar.

[0024] see now figure 1 , figure 1 It is a structural schematic diagram of a stirrup according to an embodiment of the present invention. As shown in the figure, the two J-shaped bars are upside down and are steel bar supports with the same shape and size. Each J-shaped bar is provided with a bottom bar 1 with a length of 150-200 mm. The middle part of the bottom bar and the vertical bar 2 The bottom end is connected, the bottom rod and the vertical rod are fixed vertically, the height of the vertical rod is set according to the thickness of the floor minus the thickness of the floor protective layer and the steel bar diameter of the bottom rod. degree bending;

[0025] The cross bar 3 is a steel bar, and the length is 1200-1500mm;

[0026] Among them: the two J-shaped rods are invert...

Embodiment 2

[0028] figure 2 It is a schematic diagram of the layout of the stirrup in use according to the embodiment of the present invention, image 3 for figure 2 Sectional view of A-A in Fig.

[0029] The usage method of the multifunctional stirrup for controlling the steel bar protective layer and floor slab thickness of the present invention:

[0030] 1. Provide multiple stirrups. When the stirrups are installed, place two cement pads 7 on both ends of the stirrup bottom bar 1 to ensure that the bottom bar is at the same height as the horizontal reinforcement 5 and longitudinal reinforcement 6 of the main steel bar at the bottom of the slab. Part of the distributed steel bars on the floor are placed and bound on the upper crossbar 3, and the direction of the negative reinforcement is consistent with the direction of the crossbar.

[0031] 2. The spacing between steel bar binding stirrups should be 600-800mm. The ejector rod 4 on the upper part of each stirrup is a slab thickne...

Abstract

A multifunctional stirrup for controlling thicknesses of a steel bar protective layer and a floor comprises two J-shaped rods and a cross rod and is characterized in that the two J-shaped rods are arranged in an inverted mode and are steel bar supports which are the same in shape and size; the cross rod is a steel bar and is 1200-1500 mm in length; the two J-shaped rods are arranged in the inverted mode, two bottom rod bodies are located below, two top rod bodies are located above, and the bottom rods bodies and the top rod bodies are arranged side by side at certain intervals; and the cross rod is horizontally erected and fixedly welded between two vertical rods, the cross rod is parallel to the two top rod bodies, and thus the stirrup is formed. The multifunctional stirrup for controlling the thicknesses of the steel bar protective layer and the floor has the advantages that the stirrup is simple in structure and convenient to manufacture, the heights of the vertical rods of the stirrup can be precisely processed, the plate thickness of concrete and the thickness of the protective layer of concrete negative ribs can be ensured, the construction quality is guaranteed effectively,the operating difficulty of a concrete pouring worker is lowered, and in the whole process from the concrete-poured plate face leveling to concrete face closure, ensuring of the engineering construction quality and reducing of the engineering cost are achieved through control points correspondingly.

Description

technical field [0001] The invention relates to a stirrup made of steel bars, in particular to a multifunctional stirrup for controlling the thickness of the steel bar protective layer and floor slab. Background technique [0002] In the construction of concrete structure slabs, the control of the protective layer of the floor negative reinforcement and the control of the thickness of the slab have always been a very troublesome quality problem in concrete engineering. The traditional method of slab thickness control in the pouring process is to use graduated steel bars to insert into the concrete floor slab to measure the slab thickness, which leads to poor construction accuracy. However, there is no standard for the upper part of the slab negative reinforcement protective layer, and the thickness can only be estimated by the on-site construction personnel. In this way, the thickness of the construction protective layer cannot be effectively guaranteed and it is easy to cau...
