Problems solved by technology

[0003] 1. The shape of the supporting formwork is not firm, and the fixed height cannot be adjusted flexibly;
[0004] 2. After the formwork is supported, the flatness of the side elevation of the formwork cannot be guaranteed with the concrete pouring, and the phenomenon of mold expansion generally occurs;
[0005] 3. Due to the problems caused by the formwork, the flatness of the surrounding area of ​​the floor and the stubble area is much worse than that of the central area of ​​the floor, which cannot meet the quality requirements

Embodiment

[0031] Embodiment: According to different site conditions, materials of different sizes are used to make this device:

[0032] 1. The steel plate base 1 is 400 mm long, 75 mm wide, and 4 mm thick. One end of the base has a welding plate 11 bent at 90° and 30 mm high to weld and fix the screw. Two expansion bolt holes 14 with a length of 40 mm and a width of 15 mm are provided on the steel plate base 1. , use M10 expansion bolts 7 to fix the steel plate base 1 on the concrete pad 6 . Welding screw 12 is 110 mm high and 15 mm in diameter. The bottom and sides of screw 12 are respectively welded on steel plate base 1 and welding plate 11. Screw 12 is equipped with two fixed adjusting bolts and washers for supporting and adjusting steel formwork 2. The steel plate base 1 is welded with four 4 M10 first nuts 13 to be used as pin holes for the connection of the end of the turnbuckle 3, and the use position can be determined according to the environmental conditions;

Abstract

An adjustable form special for floor construction and a construction process thereof are provided. The adjustable form special for floor construction comprises a steel plate base, a steel form and a turnbuckle. The bottom face of the steel plate base is straight. Multiple of the steel plate bases are fixed to a concrete cushion layer at designed intervals through expansion bolts. Screws perpendicular to the steel plate base are welded onto the steel plate base. The steel form is perpendicular to the steel plate base. The bottom of the steel form is fixed to the screws of the steel plate base via adjusting nuts so that multiple steel plate bases can be connected together. The turnbuckle for stabilizing the connection of the steel plate base and the steel form and adjusting evenness of a side face of the steel form is connected between the steel form and the steel plate base. The adjustable form special for floor construction is suitable for all floor construction projects having high evenness requirement, has good shaping firmness, simple structure and high adjusting precision, is convenient to mount and demount and transport, and is suitable for reuse.

Description

technical field [0001] The invention relates to a special adjustable formwork for floor construction and its construction technology. Background technique [0002] With the continuous development of the construction industry, more and more attention has been paid to the forming quality of large-area ground construction, especially for storage and other projects that have special requirements for ground flatness. High-precision floor construction has become a benchmark item for the entire project. In general, large-area ground construction often uses simple tripod brackets welded with steel bars to stabilize the formwork with the help of concrete cushions. The following disadvantages usually occur during the ground concrete pouring process: [0003] 1. The shape of the supporting formwork is not firm, and the fixed height cannot be adjusted flexibly; [0004] 2. After the formwork is supported, the flatness of the side elevation of the formwork cannot be guaranteed with the ...
