Strive to use about 10 years to make the proportion of precast buildings in the new construction area reach 30%.

Compared with the precast concrete composite slab, the 3D reinforced truss floor slab can reduce the concrete thickness by 30mm, increase the indoor clear height by 18mm, and only reduce the indoor clear height by 12mm compared with the ordinary concrete floor slab, ensuring the living comfort of the house and reducing the project cost.

Especially for factory precast concrete components, the investment in precast component equipment is large and the land occupation is large.

It belongs to semi mechanical and semi manual production.

71) proposed to develop precast buildings such as precast concrete structures, steel structures and modern wood structures according to local conditions.

The opinions of the general office of the State Council on promoting the sustainable and healthy development of the construction industry (GBF [2017] No.

Magnetic Thread Disc

Compared with precast concrete composite slabs, the production workers are reduced by 4/5, and the bottom plate weight is only 1/6 of precast concrete composite slabs.

It has simple production and construction process and convenient transportation and construction; The surface of the bottom plate is flat, which can replace the floor formwork, realize no formwork removal, no plastering, reduce the construction process, reduce the transportation cost, almost no loss, ensure the indoor clear height, reduce the project cost and other characteristics.

Wall material innovation is an important measure to protect cultivated land, save energy, improve the environment and implement the strategy of sustainable development.

Introduction and advantage analysis of 3D steel bar truss floor slab 3D steel bar truss floor slab is a three-dimensional composite floor bearing slab that connects the steel bar truss and the fiber cement slab (without dismantling the bottom formwork).

It is suitable for concrete and steel structure cast buildings in areas with seismic fortification intensity of 8 and below.

Click the blue word to focus on our video preview 3D cast steel truss floor slab on-site actual shooting of seven star equipment intelligent manufacturing project background and industry analysis national cast development policy with the implementation of energy conservation and environmental protection policy, the R & D and production of new wall materials is an inevitable path for the development of the construction industry.

The floor slab thickness is generally 12mm, which does not participate in the structural stress calculation.

Based on the current and future market potential for the development of precast buildings.

According to the traditional reinforced concrete floor slab design, it is not necessary to set post cast strip 3D reinforced truss floor slab.

There is no need for complex processes such as pouring concrete and autoclaving.

To ensure the indoor clear height, the project cost is relatively low.

It is one of the most widely used components in precast buildings.

The full-length transverse load-bearing reinforcement can be arranged on the upper side of the bottom plate, and the joint of the slab joint does not need to be provided with a concrete post cast strip, which is convenient for construction.

The guiding opinions of the general office of the State Council on vigorously developing precast buildings (GBF [2016] No.

The floor slab design is based on the ordinary cast-in-place concrete floor slab, and the design calculation is simple.

All 3D reinforced truss floor slabs are produced by automatic production lines.

The processes of mold assembly, reinforcement binding and concrete tamping are all manual operations.

The production process is simple and convenient for transportation and construction.

Atlas regulations#.

The production process of traditional precast concrete composite plate is complicated and the degree of automation is low.

19) proposed to vigorously promote intelligent and precast buildings.

The equipment investment is small, the degree of automation is high, and the production process is simple.

The outline for the modernization development of the construction industry points out that by 2025, precast buildings will account for more than 30% of new buildings, more than 40% of municipalities directly under the central government, cities specifically designated in the state plan and provincial capital cities, and more than 50% of affordable housing projects will be constructed by precast buildings.

Strive to use about 10 years to make the proportion of precast buildings in the new construction area reach 30%.

At the same time, it is also of great significance to promote the structural adjustment and technological progress of wall materials, improve the quality of construction projects and improve building functions.

The structural design of QX series 3D cast reinforced truss floor slab of construction project Qixing industry is scientific and reasonable, with leading technology, high degree of equipment automation, low labor cost, high production efficiency, energy conservation and environmental protection, stable and reliable product quality, mature construction application technology, good application effect, obvious economic benefits, and strong technical leadership and market competitive advantage.

The transportation and construction are convenient, and the production and installation labor cost is low.
