Problems solved by technology

[0002] With the continuous development of the construction market, low-cost competition is becoming more and more prominent. At the same time, the society is also vigorously advocating building energy conservation and environmental protection. The traditional concrete floor formwork system is mainly based on support and wood. The keel does not meet the requirements of energy saving, environmental protection and low cost. The improvement of the concrete floor formwork system is imperative, and new breakthroughs and innovations must be made

Embodiment 1

[0051] Concrete floor shaped steel frame formwork system embodiment, see Figure 1 to Figure 8 ,like Figure 1 to Figure 3 As shown, the formwork system includes a square steel beam 1, a steel frame 2 made of shaped square steel, a saddle beam 3, a vertical bar 4, and a cross bar 5 through steel plate molding; the cross bar is connected with the fastener 4-1 Adjacent poles are tied and fixed, U brackets 6 are installed on the poles, square steel beams are installed on the U brackets as the main keel, saddle beams are placed on the main keel, steel frames are placed on the saddle beams as secondary keels, and laid on the steel frame The formwork 7 is poured with a concrete floor 8 on the formwork.

[0052] The distance between the poles and the poles, when the thickness of the floor is 100 mm to 250 mm, the distance between the poles is 950 mm × 650 mm (950 mm × 650 mm is a common name in the industry, the actual length and width of the poles are 950 mm and 650 mm;) ; When th...

Embodiment 2

[0058] An embodiment of the construction method of the concrete floor shaped steel frame formwork system. The construction method is realized on the basis of Embodiment 1, and its technological process is as follows:

[0059] Elevation line of spring slab support formwork → place pole cross positioning line → install pole skid and pole → install cross bar → install U bracket → install square steel beam → install saddle beam → install shaped steel frame → pull wire leveling → full pavement Multi-layer board formwork → adjustment, arching, reinforcement → cleaning → inspection and acceptance → formwork removal;

[0060] The specific process steps are:

[0061] a. Steps to play the elevation line of the formwork support on the wall and the cross positioning line of the vertical pole:

[0062] After the wall formwork is removed, the horizontal control line that controls the formwork elevation is played on the wall, and the pole cross positioning line is placed according to the fo...

Abstract

The invention relates to a standard steel frame formwork system for concrete floor slabs and a construction method thereof. The system comprises square steel girders, steel frames, saddle girders, vertical bars and cross bars, wherein the cross bars are tied and fixed with the adjacent vertical bars by fasteners; U supports are installed on the vertical bars; the square steel girders are installed on the U supports and serve as main keels; the saddle girders are placed on the main keels; the steel frames are placed on the saddle girders and serve as secondary keels; and formworks are paved onthe steel frames. The construction method comprises the following process flows: snapping floor slab formwork erecting elevation lines; placing cross position lines of the vertical bars; installing vertical bar crossers on the cross position lines; installing the vertical bars; installing the cross bars; installing the U supports; installing the square steel girders; installing the saddle girders; installing the standard steel frames; levelling lines; paving multi-layer slabs fully; adjusting, arching and reinforcing; cleaning; inspecting and accepting; and removing the formwork. The system and the construction method have the following beneficial effects: the system has the characteristics of factory processing and tool-typed installation; and the construction method has the advantages of good stability, safety, reliability, time and labor saving, high construction speed and high turnover rate, can save lots of wood and funds, and meets the requirements for energy saving, environmental protection and economic benefits.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a shaped steel frame formwork system for concrete floors and a construction method thereof, and is especially suitable for a shaped steel frame formwork system for concrete floors with shear walls and frame structures. Background technique [0002] With the continuous development of the construction market, low-cost competition is becoming more and more prominent. At the same time, the society is also vigorously advocating building energy conservation and environmental protection. The traditional concrete floor formwork system is mainly based on support and wood. The keel does not meet the requirements of energy saving, environmental protection and low cost. The improvement of the concrete floor formwork system is imperative, and new breakthroughs and innovations must be made. Contents of the invention [0003] In order to solve the above problems, the concre...
