The Steel Truss Floor bearing Plate
The steel truss floor bearing plate is a composite floor bearing plate in which the steel bars in the floor are processed into steel truss by imported equipment in the factory, and the steel truss and galvanized plate are welded into one body in the factory. In the construction phase, the steel truss floor plate can withstand the construction load, laydirectly on the beam, and carry out simple steel works, then the concrete can be poured. Since the formwork function is completely replaced, the formwork erection anddisassembly works are reduced, and the floor construction efficiency is greatly improved.

Product composition Upper string reinforcement, lower string reinforcement, belly bar reinforcement, bottom die, support reinforcement.
Material parameter 1. The upper and lower string steel bar: the use of three hot rolled coil steel HRB400, HRB300; 2. The belly bar steel bar: the use of three hot rolled coil steel HRB400 or performance equivalent to CRB550 cold rolled garden steel bar; 3. Support transverse reinforcement: vertical reinforcement using three-stage hot rolling disc screw HRB400, HRB300; 4. Bottom die steel plate: the use of Q235 cold rolled steel plate or not less than S250GD+2 grade galvanized steel plate, galvanized quantity of both sides is not less than 120g/m.
Technical Parameter Bottom die steel plate width (mm) 576mm/600mm Product length (m) 1.0-12.0 Template thickness h(mm) 100-300 Steel truss height ht(mm) 70-270 Thickness of concrete protective layer C (mm) 15(15mm above and below truss) Bottom die steel plate thickness (mm) 0.5mm-0.8mm

Removable soffit formwork steel truss floor plate
● Duration: No scaffolding, formwork process, reduce the amount of on-site steel binding 30% ~ 80%, reduce the site material lifting time, and can be multi-layer three-dimensional construction, speed up the construction period.

● Quality: Convert on-site manual work into factory equipment production, reducing human necessity Control factors, steel bar spacing and concrete protective layer thickness meet Design requirements, floor quality is more reliable.

● Safety: By reducing intensive manual work such as wood formwork and binding of steel bars, The probability of fire, casualties and other safety accidents is reduced, and the on-site construction is reduced.Management difficulty, civilized construction, safety is guaranteed.

● Cost: Reduced a lot of scaffolding, wood formwork and other temporary measure material costs, Reduce a lot of labor costs and a lot of equipment rental costs, And due to the shortening of the construction period, the cost of capital occupation is reduced and increased a substantial advance profit.

1. General introduction of removable bottom formwork reinforced truss floor bearing plate Removable bottom mold reinforced truss floor bearing plate: through the bottom plate fastener and screw connection, after the completion of pouring, only First remove the screw of the bottom plate with the electric wrench, and then remove the bottom plate without secondary plastering (The bottom connecting piece technology is developed to ensure the flatness of the bottom).

2. Production and transportation are flexible and convenient Removable bottom formwork reinforced truss floor bearing plate: ①Company production, delivery site installation; ②only the base plate, steel truss and fastener are sent to the site, and the equipment is independently developed by Zhongyi/Taibo company . The removable bottom formwork reinforced truss floor bearing plate can be assembled on site, and the assembly of the floor bearing plate can be applied according to the actual site Work area for assembly.

3. Pouring effect comparison After the original pavement of the removable floor bearing plate is completed, when there is no connection piece, Self-tapping screws is used on the bottom formwork to make the connection between the plates into an overall plane (see attached Figure 4), so that the construction effect rate is low, the cost is high, and the quality can not be guaranteed after pouring. (as FIG. 5),After the development of the connecting piece technology (Zhongyi/Taibo independent research and development of patented technology), at the bottom formwork every 400mm a level balance connecting piece is used (see attached figure 1) cross dislocation connection, to prevent the dislocation between the plate and the plate, so that the board can become a plane between the floor to ensure the flatness of the bottom of the floor, and improve the construction speed, do not need secondary plastering, which can be directly transferred to the decoration. (See Annex III) assembly area.
4.The construction schedule planning comparison
Assembling removable reinforced truss floor bearing plate, actual case (Longfor Group Zhejiang Company Zijing Port project) One day 6-7 people can pave 1000 square meters (see attached figure 2), which effectively shorten the construction period, it is faster 30% than the installation of self-supporting floor bearing plate, more convenient to dismantle, 1400 square meters of board can be fully removed by 6 people in a day.
Prefabricated building products HPC Assembled Composite Floor Slab (Without demoulding)
Ultraplate The minimum plate thickness after pouring is 100mm It can realize multi-plate thickness construction as well as the thickness of cast-in-place floor Save the indoor net height, reduce the cost of structure and foundation
Industrial production Proprietary automatic production line 2000 square plant can produce 2000 square meters per day High production efficiency, low plant and equipment investment can indirectly reduce cost.
Lightweight and efficient The finished bottom plate is 30kg/㎡, and the conventional plate type can be easily handled and constructed by only two people, greatly improving the processing, transportation, construction efficiency and saving the tower crane to reduce the installation cost.
Support Quantity is less. The unsupported construction span is large, and when the maximum unsupported span of the slab is exceeded in the field pouring, only a temporary support is needed in the slab span, which greatly reduces the on-site support cost.
Easy pre-embedded The minimum clearance of the upper truss of the bottom plate is 55mm, which increases the allowable diameter of the in-situ embedded pipeline, facilitates the in-situ pipeline embedment and reduces the embedment cost
