The project of precast stairs of precast shear wall with laminated slab is deepened through pkpm-pc.

Fixing Socket Cross Hole

The same approach is more incisively and vividly reflected in the shear wall, because the mold price of vertical components such as shear wall is higher than that of laminated plate, so reducing the number of molds will have a more significant effect on cost reduction.

The main precast components are precast shear wall, precast laminated plate and precast stairs.

pkpm-pc case solicitation is ongoing! We will continue to show the application of pkpm-pc software in precast building cases.

The most important thing is to avoid the problems of wrong embedment and missing embedment of manual layout.

The precast components applied are: Precast shear wall, precast laminated plate Precast stairs.

Just import the drawings and identify them according to the layer blocks, and then the reservation and embedment of openings, junction boxes, etc.

Before the deepening of the project, the most easily overlooked factor is the tower crane that is not reflected in the civil engineering drawings, but in fact this factor is very important.

can be generated quickly.

Designers are welcome to share pkpm-pc software related building cases.

When splitting, the laminated plate is divided into the same size and the same reinforcement as far as possible, so as to improve the common mode rate of the laminated plate.

After the design is completed, the detailed drawings and BOM of the project are obtained with high efficiency and high quality through one click drawing of the software.

Secondly, in the tower crane layout, considering the factors such as formwork utilization rate, reinforcement binding efficiency, production efficiency and later construction efficiency, precast components should be combined with less specifications as much as possible, reduce the number of molds and improve the economic efficiency Economic effect and cost reduction.

The efficiency is very high.

The author introduces ou YangZheng, structural engineer, technical manager of the technical department of Sichuan Huaxi lvshe building materials Co., Ltd.

It has been optimized to only need one type of mold, which greatly improves the production efficiency and reduces the project cost.

Therefore, in the detailed design of the project, the splitting scheme and reinforcement scheme of the laminated plate are optimized.

The whole process design is carried out through pkpm-pc assembly design software to meet the requirements of 50% assembly rate of the project, and the detailed drawings of various precast components are completed with high efficiency.

Finally, it is also necessary to check the reinforcement of laminated plates, precast shear walls and precast stairs, as well as the corresponding water and electricity reservation and embedding, setting out holes, tensile anchorage and various embedded parts on the precast components, so as to ensure that the design does not omit or make mistakes, and ensure the accuracy of the design of precast components.

and the application of the third prize project of Sichuan design competition.

For reservation and embedment, the electromechanical CAD drawings can be identified in pkpm-pc to automatically generate the function of hydropower reservation and embedment.

The project has also made corresponding optimization for the precast shear wall to reduce the types of molds.

Project summary: this project is a conventional residential project.

The project meets the requirements of assembly rate of 50% through the calculation rules of assembly rate of precast buildings in Sichuan Province.

Many projects are not fully considered in the early stage, and the reason for large-scale modification after deepening is that the impact of the tower crane on the tonnage of precast components is not considered, so when starting the project, The designer considered the influence of tower crane on deepening design, According to the tower crane model QTZ80 arranged on site (6013) and tower crane plane layout to deepen the design of precast components, control the weight of precast components, and avoid the problem that precast components cannot be lifted when transported to the site.

Project index: assembly rate of 50%.

The planned net land area of the project is 22392.93 m2, with a total construction area of about 90577.03 m2, which is composed of residential and supporting service houses.

according to the detailed design process of prefabrication attribute designation → splitting → detailed design → reserved and embedded layout → inspection of various indicators, step by step, we can quickly get the detailed design results of the project.
