Description

Technical Field

[0001] The utility model belongs to the technical field of construction, in particular to an assembled integral composite board. Background Art

[0002] In recent years, the domestic prefabricated building industry has entered a stage of vigorous development. Prefabricated composite floor slabs, as an important component of prefabricated structures, have become the most commonly used prefabricated components in domestic prefabricated buildings due to their advantages such as simple production, convenient installation and reliable performance compared with other types of prefabricated components.

[0003] With the increasing application of prefabricated composite floor slabs, its shortcomings in design, production, construction, etc. have also been exposed:

[0004] 1) The overall thickness of prefabricated composite floor slabs is generally 130mm (60mm prefabricated + 70mm cast-in-place), which is 10mm thicker than the 120mm commonly used cast-in-place slabs. This increases the amount of concrete and affects the net height of the floor;

[0005] 2) Prefabricated composite floor slabs use truss steel bars due to their thin prefabrication thickness. The web steel bars only play a mechanical role during the construction phase, and the amount of steel bars used is increased.

[0006] 3) When the span of prefabricated composite floor is large, the weak prefabricated layer cannot resist the mid-span bending moment. Temporary support needs to be set up under the slab during the construction stage, which not only increases the construction process and cost, but also affects the construction of the secondary structure of the next floor;

[0007] 4) During the construction phase, prefabricated composite slabs do not have a very obvious construction period advantage compared to cast-in-place slabs. They only save the work of supporting the bottom formwork and bottom reinforcement binding. After installation, there is still a lot of work such as surface reinforcement binding, pipeline pre-embedding and composite layer concrete pouring. The amount of wet work on site is still large and it is impossible to quickly provide a working surface for subsequent floor construction. Utility Model Content

[0008] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an assembled integral composite plate, which effectively solves the problems raised in the above background.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an assembled integral composite slab, including a prefabricated full-thickness main body of a floor slab, wherein the outer end of the prefabricated full-thickness main body of the floor slab is provided with a surrounding partial prefabricated area, and an on-site post-cast reinforced concrete area is provided between the upper end of the surrounding partial prefabricated area and the prefabricated full-thickness main body of the floor slab.

[0010] Preferably, main reinforcements are evenly arranged on the upper side of the interior of the prefabricated full-thickness main body of the floor slab, and secondary reinforcements are evenly arranged on the lower end of the main reinforcements, and the secondary reinforcements are arranged perpendicular to the main reinforcements.

[0011] Preferably, the main reinforcement of the bottom slab is evenly arranged on the lower side of the interior of the prefabricated full-thickness main body of the floor slab, and the secondary reinforcement of the bottom slab is evenly arranged on the upper end of the main reinforcement of the bottom slab, and the secondary reinforcement of the bottom slab is arranged perpendicular to the main reinforcement of the bottom slab.

[0012] Preferably, the thickness of the surrounding prefabricated area is greater than or equal to 60 mm, and the length from the edge of the surrounding prefabricated area to the side end of the prefabricated full-thickness main body of the floor slab is greater than or equal to 300 mm.

[0013] Preferably, the full-thickness main body thickness of the prefabricated floor slab is greater than or equal to 120 mm.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) Compared with prefabricated composite panels, the utility model greatly improves the prefabrication rate of assembled integral composite panels, reduces the workload of on-site steel bar binding and wet operations, transfers a large amount of on-site steel bar binding, pipeline pre-embedding and concrete wet operations to the factory, and uses mechanized production to replace backward manual operations. It is energy-saving, environmentally friendly and reliable in quality, which is conducive to promoting the development of building industrialization and has significant social benefits.

[0016] (2) There is no need to set truss reinforcement in the slab and increase the overall slab thickness, which saves the amount of reinforcement and concrete;

[0017] (3) On-site construction is convenient and efficient. The assembled integral composite panel can be installed without support. After installation, it can provide a working surface for subsequent processes to insert and construct, which can significantly shorten the construction period and establish a good engineering image.

[0018] (4) This new type of composite slab adopts assembled integral composite slab instead of prefabricated composite slab construction. The concrete is poured on site only at the joints around the slab, and the rest of the joints are prefabricated as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment 1, by Figure 1-Figure 2 The utility model comprises a prefabricated full-thickness main body 3 of the floor slab, the outer end of the prefabricated full-thickness main body 3 of the floor slab is provided with a surrounding partial prefabricated area 1, and an on-site post-cast reinforced concrete area 2 is provided between the upper end of the surrounding partial prefabricated area 1 and the prefabricated full-thickness main body 3 of the floor slab;

[0029] The thickness of the prefabricated full-thickness main body 3 of the floor slab is greater than or equal to 120 mm.

[0030] Working principle: The assembled integral composite slab is in a simply supported state during the construction phase. Under its own weight and construction load, the mid-span bending moment of the slab is the largest, and the end bending moment is reduced to zero. Since the middle part of the slab is prefabricated with full thickness, the full-section bending resistance can be achieved; the thickness of the surrounding parts is prefabricated, and the bending moment of the surrounding parts is also small; during the use phase, the full-section bearing is also achieved around the slab. After two-stage verifications during the construction phase and the use phase, the assembled integral composite slab can achieve the purpose of unsupported construction of the slab without increasing the slab thickness and steel bars compared to the prefabricated composite slab.

[0031] The assembled integral composite slab is suitable for the construction of floor slabs in assembled steel structure projects, and is particularly suitable for the construction of floor slabs in assembled steel structure projects that adopt standardized and modular designs.
