Embodiment 1

[0024] refer to Figure 1-2 As shown, a control device for inter-slab thickness of reinforced concrete includes a ribbed steel bar 1, a steel bar sleeve 2 sleeved on the ribbed steel bar 1, and a bottom positioning thinner arranged under the ribbed steel bar 1. Steel plate 3, and the concrete block 4 that is arranged under the bottom positioning thin steel plate 3, and the top positioning thin steel plate 5 that is arranged above the ribbed steel bar 1, and the thin steel rod 6 that is arranged on the side of the top positioning thin steel plate 5, in In this embodiment, the thin steel rod 6 used can be replaced by a steel wire rope.

[0025] The steel bar sleeve 2 is set in the middle of the ribbed steel bar 1, the bottom positioning thin steel plate 3 is set in an inverted U shape, and is set in a cover shape above the concrete pad 4, and the height of the lower part of the deck is 25mm concrete block 4 to ensure the thickness of the protective layer of the lower reinforcem...

Embodiment 2

[0029] refer to Figure 1-2 As shown, a method for controlling the inter-slab thickness of reinforced concrete includes the following steps:

[0030] 1) Select a ribbed steel bar 1, and insert a steel bar sleeve 2 on the ribbed steel bar 1;

[0031] 2) welding an inverted U-shaped positioning thin steel plate at the bottom of the ribbed steel bar 1;

[0032] 3) Install the inverted U-shaped positioning thin steel plate on the bottom reinforcement of the concrete floor;

[0033] 4) Weld flat-plate positioning thin steel plates on the top of the ribbed steel bar 1;

[0034] 5) Weld thin steel rods 6 on the outer periphery of the flat plate positioning thin steel plate;

[0035] 6) Place the concrete floor gluten on the top thin steel plate, pass through the thin steel rod 6 and form a cross shape;

[0036] 7) Pour concrete on the concrete formwork, and embed the above structure in the concrete floor to form a whole.

[0037] In step 1), the upper and lower ends of the ribbe...

Abstract

The invention discloses an inter-plate thickness control device for reinforced concrete. The inter-plate thickness control device comprises a ribbed steel bar, a steel bar sleeve, a bottom positioning thin steel plate, a concrete cushion block, a top positioning thin steel plate and thin steel bars, wherein the ribbed steel bar is sleeved with the steel bar sleeve, the bottom positioning thin steel plate is arranged below the ribbed steel bar, the concrete cushion block is arranged below the bottom positioning thin steel plate, the top positioning thin steel plate is arranged above the ribbed steel bar, and the thin steel bars are arranged on the peripheral side of the top positioning thin steel plate. The inter-plate thickness control device for the reinforced concrete can meet the requirement for controlling the thickness of a surface gluten protective layer of a double-layer plate rib.

Description

technical field [0001] The invention relates to a thickness control device for reinforced concrete. Background technique [0002] In the process of my country's modernization construction, higher requirements are put forward for construction engineering construction. In construction construction, especially large-scale construction projects, the quality and safety requirements for various sub-projects of the project are also getting higher and higher. At present in China, reinforced concrete is the most widely used structural form, accounting for the vast majority of the total. The reason why reinforced concrete can work together is determined by its own material properties. First of all, steel bars and concrete have approximately the same linear expansion coefficient, and excessive stress will not be generated due to different environments. Secondly, there is a good bond between the steel bar and the concrete. In addition, the alkaline environment provided by calcium hyd...
