Description
Technical Field
The invention relates to the technical field of concrete structures in civil engineering, in particular to an assembled double-T plate, and specifically relates to a herringbone frame rib plate assembled double-T plate.
Background
At present, assembly type building has become the development trend of building trade, and the production preparation of prefabricated component is its essential component part, and beam and board are combined as an organic whole with its unique structural style to two T boards wherein, have fine structural performance, quick construction progress, lower construction cost can make the bearing member of large-span, large coverage area, relatively economy. The double T-shaped plate consists of a wing plate and two rib plates, wherein the wing plate not only has the function of a plate as a direct bearing surface for external load, but also is a flange when the double T-shaped plate is used as the function of a T-shaped beam. The wing plate has the characteristics of multiple functions of one material, and compared with the traditional beam plate system, the double-T plate can save materials and reduce working procedures.
When the span of the double T-plate is large, it has to be made on site due to its large edge size and large space, which is limited by transportation. The problem that the double T-shaped plates are manufactured on site still exists, namely the large space volume of the integral double T-shaped plates occupies a large amount of storage yards, and a lot of projects cannot meet the stacking requirements and are difficult to use. And even when the length of the double T-shaped plate is small, the double T-shaped plate occupies a large cargo space, so that the transport capacity is limited, the transportation cost is increased, the engineering progress is delayed, and the popularization of the double T-shaped plate is not facilitated. In addition, the field open cast-in-place manufacturing of the double T-shaped plates is also influenced by typhoon, heavy rain and the like, and the progress is also influenced. Practice proves that: the traditional construction method for integrally manufacturing the double T-shaped plates is a bottleneck which seriously restricts the construction period, often leads to the doubling of the construction period and can not embody the advantages of the fabricated building.
In the existing innovative technology, a technology of separately prefabricating a wing plate and a rib plate and then combining the wing plate and the rib plate into an integral double-T plate is provided, so that the problems are solved. However, practical and theoretical engineering studies have shown that: when the span of the double-T plate is large, along with the increase of the span, the increase of the self weight of the double-T plate is not linear increase, but is nonlinear increase along with the increase of the span, and the construction cost is also nonlinear increase. The main reason is that the increase of the height of the rib plate is non-linear, the increase of the self weight of the rib plate is also non-linear, the rib plate is made into a truss form, the problem can be solved, but the storage and transportation space required by the integral prefabrication of the truss and the complex reinforcement of the truss restrict the idea.
Therefore, to solve the above problems, further innovative methods are required.

Compared with the integrally prefabricated truss or the double T-shaped plate with the rib plates arranged as the truss, the truss form saves materials and reduces self weight compared with a solid plate, but the prefabrication requires complicated and expensive moulds and complicated arrangement of ribs in the integral truss, so that the aforementioned advantages of the truss are partially offset. The herringbone frame rib plate is adopted, the web members of the truss are decomposed into simple basic units, the repetition rate is improved, the mold cost is saved, the reinforcement is standardized and simplified, the advantages of the solid type rib plate and the truss type rib plate are integrated, the respective defects are abandoned, and the herringbone frame rib plate is an optimized concept.

Holes are formed in the wing plates, and the upper ends of the herringbone brackets are arranged in the holes of the wing plates. The wing plate material is a concrete, steel or steel concrete composite material.
Furthermore, the wing plates are arranged in a sectional mode, the wing plates of each section are arranged into wing plates, holes are formed in the wing plates, and the upper ends of the lambdoidal frames are arranged in the holes of the wing plates.

1. the herringbone frame gives full play to the advantage of truss stress, reduces the dead weight of a rib plate of the herringbone frame, reduces materials with lower efficiency in a solid rib plate, improves the utilization rate of the materials, and enlarges the span of the double T plates in an efficient mode;
2. the herringbone frame ribbed slab takes a single herringbone frame as a basic unit, the prefabrication repetition rate is greatly improved, the advantages and the strength of the prefabricated assembled type are exerted, after the solid ribbed slab is arranged into the truss type ribbed slab, a steel die used during concrete prefabrication is more complicated and the cost is increased sharply, after the herringbone frame ribbed slab is adopted, the steel die used during prefabrication becomes extremely simple and the cost is obviously reduced, compared with a double T-shaped slab of the integral solid ribbed slab, the cost of the steel die is reduced from the ten-thousand-element level and the million-element level to the thousand-element level and the hundred-element level, the disadvantage that the prefabricated assembled type steel die occupies a large ratio is completely improved, and the prefabricated assembled type steel die is beneficial to application and popularization of the prefabricated assembled type;
3. the cost of a steel mould of the wing plate is obviously reduced as the cost of a propeller strut when the wing plate is prefabricated in sections;
4. the storage and transportation cost of the herringbone frame rib plate double T plates is greatly reduced, and the convenience is obviously improved;
5. the double-T plate is assembled on site, and because each piece has reached the strength in advance, the double-T plate can be assembled in severe environments such as rainy days and low temperatures only under the condition that partial rainproof measures (such as a worker wearing an umbrella or a rain cape) are needed, and the construction speed is accelerated.
