Problems solved by technology
The construction of ordinary reinforced concrete cast-in-place beam and slab structures has high technical requirements for workers, high labor intensity, high wood consumption, easy deviation of beam cross-sectional dimensions, poor seismic performance, the need to use a lot of scaffolding, a large amount of construction waste, and fire-resistant time Shorter, poor fire resistance and other issues
Moreover, it is cumbersome and time-consuming to bind the reinforcement cage between the formwork on site.

Embodiment Construction
[0039] The present invention will be further described in detail below with reference to the drawings and specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.
[0040] A multi-ribbed floor free-support assembled formwork device includes a support frame and a prefabricated formwork 1. The prefabricated formwork includes two first unit templates 1-1 and a second unit template 1-2. One unit template is connected by the buckle cover type fixing members 1-3 on both sides of the second unit template to form a complete prefabricated template. The prefabricated template is installed on the support frame to form a complete free-support assembled template.
[0041] The first unit formwork includes a bottom formwork frame 1-5, a formwork, a steel cage, and a fixing member 1-4. The bottom formwork frame is a mesh grid frame body, and the upper surface of the formwork is sequentially...

The invention relates to a support-free fabricated formwork device for a multi-ribbed floor system. The support-free fabricated formwork device comprises a supporting frame and a prefabricated formwork. The prefabricated formwork includes two first unit formwork plates and a second unit formwork plate. A complete prefabricated formwork plate is formed between the two first unit formwork plates through the connection of buckle cover type fixing members on the two sides of the second unit formwork plate, and the prefabricated formwork plate is installed on the supporting frame to form a completesupport-free fabricated formwork plate. The invention further provides a construction method of the support-free fabricated formwork device for the multi-ribbed floor system. The for a multi-ribbed floor system is simple in structure and convenient to install, can be fabricated on site, and can be reused, the construction cost is reduced, the disassembly and assembly construction processes of full or striped paving can be simplified, and through the cooperative supporting of the supporting frame, an underframe formwork frame and a reinforcement cage, the self-load of the formwork device is greatly increased.
Description
Technical field [0001] The invention belongs to the field of construction technology, and relates to multi-ribbed formwork technology, in particular to a multi-ribbed floor slab support-free assembly type formwork device and a construction method. Background technique [0002] In the past ten years, concrete multi-ribbed beam floors have been widely used in my country's construction projects. The floor form has the characteristics of low floor structure, light weight of the floor, low amount of cast-in-place concrete and steel, fast construction period, suitable for large-span structures, etc., so it is widely used in large shopping malls, exhibition halls, and sports Multi-high-rise commercial and public buildings such as museums, warehouse buildings, libraries, underground structures, teaching buildings, office buildings, etc., are especially commonly used in structural types with large space, large span, and high headroom requirements. [0003] There are two main types of multi...
