Description

Building node structure with notch assembled full-prefabricated floor slab and supporting members

Technical Field

The utility model relates to a building structure, concretely relates to take full precast floor slab of notch assembled and supporting member's building node structure.

Background

With the research and the vigorous popularization of the prefabricated concrete building in China, the prefabricated concrete structure is developed in China.

The existing prefabricated reinforced concrete prefabricated floor slab can be transported to a construction site for installation after being processed and molded in advance in a factory, so that the construction period of the prefabricated floor slab can be greatly shortened, and the construction cost is reduced. The floor slab is a main component in the building, the number of the floor slab is equivalent to the building area, and the manufacture of the floor slab is very important in the whole building construction process. Along with the continuous development of building construction modernization, the large-space and large-span floor system is rapidly increased.

In the early development stage of the fabricated building, the prefabricated composite floor slabs are used more. The bottom surface of the laminated slab is prefabricated in a factory, and the flatness of the laminated slab is better than that of a wood mold for a cast-in-place structural floor slab. Along with the research of the fabricated concrete building, particularly after the aluminum mold is popularized, the flatness of the cast-in-place structure is also guaranteed. The problem of prefabricated composite floor slabs slowly emerges, and the full prefabricated slabs are increasingly applied to fabricated buildings.

Compared with prefabricated laminated slabs, the fully prefabricated slab has the following advantages:

1. for fabricated structures, the full precast floor plan is superior to the composite floor plan in terms of structural increments. The thickness of the prefabricated laminated plate is not smaller than 60mm, the thickness of the post-cast concrete laminated layer is not smaller than 60mm, and 70mm is generally adopted in consideration of the pre-embedding of pipelines of the post-cast concrete laminated layer. Traditional superimposed sheet adds the thickness of post pouring concrete superimposed sheet and will reach 120mm or more than 130mm, and to comparatively common high-rise residence in the market, the floor is usually designed into 100 ~ 110 mm. If the whole prefabricated floor slab adopts the cast-in-place slab thickness, the total concrete consumption of the corresponding whole prefabricated floor slab scheme is lower than that of the composite floor slab scheme. The total increase in concrete of the prefabricated composite floor slab solution structure may also cause an increase in the load on the structure, and the design of the foundation may require a corresponding increase in load to be taken into account, which may cause an increase in the cost of construction of the foundation.

2. The thickness of the whole prefabricated floor slab is the same as that of the cast-in-place floor slab, so that the number of prefabricated components can be reduced, and the production, construction and installation efficiencies are improved.

Because the thickness of the traditional laminated slab is 60mm or 70mm, in order to avoid cracks or deflection in the production and construction and installation processes of components, the maximum value of the national standard atlas, "truss reinforced concrete laminated slab" 15G366-1 does not usually include the width of about 2.1 meters of reinforcing steel bars. For the fully prefabricated floor slab, the slab width and the slab length can be split according to transportation limitation, and large prefabricated components are used as far as possible, so that the number of the prefabricated components is reduced, the production efficiency is improved, and the hoisting times are reduced.

Meanwhile, the scheme of the fully precast floor slab only needs to consider the cost of one-time integral installation, and the scheme of the laminated slab needs to consider the relevance of installation, steel bar binding of a cast-in-place layer, concrete pouring, a cement mortar integral surface layer and a corresponding cast-in-place belt template, so that vertical transportation equipment is correspondingly occupied, and the fully precast floor slab scheme is more economic than the laminated slab scheme in cost and cost. The number of processes of the laminated slab is increased in the construction period, which causes delay of the construction period.

3. The production cost of the components of the full precast floor slab is lower than that of the laminated slab.

If the laminated slab needs to be considered to be connected with the cast-in-place concrete laminated layer according to the production cost of each cube, truss ribs are usually required to be arranged, the quantity of the steel bars is higher than that of a fully prefabricated floor slab, and the cost of auxiliary materials required by each cube of concrete is relatively higher. Considering the production period, the number of the full precast floor slabs can be less than that of the laminated slab in the splitting process, and the corresponding mold cost and the manufacturing cost are lower than those of the laminated slab. Comprehensively, the production cost of the components of the fully prefabricated floor slab is lower than that of the laminated slab.

4. The full precast floor slab is reinforced according to the actual use, is more convenient than the precast composite slab in the transportation and hoisting process, and is not easy to crack.

5. The floor can be pre-buried with conventional pipelines according to actual projects.

The thickness and the structure of the full precast floor slab can be adjusted according to actual items, various building function requirements are met, and the full precast floor slab is integrally installed on equipment pipelines.

6. In terms of construction sites, the fully prefabricated floor slabs are more environment-friendly than the site where the laminated slab is applied, the site operation personnel are fewer, and the support is simpler than that of the laminated slab.

Due to the existence of the cast-in-place laminated layer, a large number of wet operation links such as steel bar binding, concrete pouring and the like are bound in the laminated slab, and although the labor amount, the templates, the supports and the like of field operation personnel for casting are reduced to some extent compared with the field operation personnel for casting, the wet operation links, the templates and the supports can be greatly reduced in the application field of the full precast floor slab. The scene appearance is cleaner and tidier, and the social benefit is more obvious.

7. The structure stress of the full precast floor slab component is safe and reliable.

The traditional laminated slab adopts truss ribs in consideration of the integral stress of the laminated slab and the laminated cast-in-place layer, large-area cast-in-place and prefabricated contact surfaces exist, and if field construction personnel do not treat the junction of the prefabricated layer and the cast-in-place layer, concrete can be directly poured, and cracks of a floor slab can be generated after construction. And the whole precast floor slab is integrally poured, so that the stressed integrity of the precast slab can be ensured.

In summary, the fully precast floor slabs have strong development advantages compared with the laminated slabs, but the existing joints, lap joint structures, construction stability and the like containing the fully precast floor slabs need to be further improved.
