Description
Technical Field
The utility model relates to a building structure specifically indicates a full precast floor of 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 greatly 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.
At the early development stage of the fabricated building, more prefabricated composite floor slabs are used. 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 the prefabricated laminated slab, 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. The thickness of traditional superimposed sheet adds post-cast concrete superimposed sheet and wants to reach 120mm or more than 130mm, and to comparatively common high-rise residence in the market, the floor is usually designed for 100 ~ 110 mm. If the full precast floor slab adopts the cast-in-place slab thickness, the total concrete consumption of the corresponding full precast floor slab scheme is lower than that of the laminated 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 full precast slab is the same as that of the cast-in-place floor slab, so that the number of precast components can be reduced, and the production, construction and installation efficiency is 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 split fully-prefabricated floor slabs is less than that of the laminated slabs, and the corresponding mold cost and manufacturing cost are lower than those of the laminated slabs. 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 actual use, is more convenient than a precast laminated slab in the transportation and hoisting processes, and is not easy to crack;
5. the floor can be according to the pre-buried conventional pipeline of actual project
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 reinforcement binding and concrete pouring are inevitably existed in the laminated slab, and although the labor amount, the templates, the supports and the like of field operation personnel for cast-in-place are reduced to some extent, the wet operation links, the templates and the supports can be greatly reduced on the application field of the full precast floor slab. The scene appearance is cleaner and tidier, and the social benefit is more obvious.
7. Structure stress safety and reliability of full precast floor slab component
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 site constructors can directly pour concrete if the junction of the prefabricated layer and the cast-in-place layer is not processed, so that the cracks of the floor slab after construction can be caused. And the whole precast floor slab is integrally poured, so that the stressed integrity of the precast slab can be ensured.
