I. Product Profile and Usage
Composite hollow building formwork equipment is a new type of environmental protection plastic building formwork equipment independently developed and successfully developed by Qingdao Yijinwei Plastic Machine Co., Ltd. on the basis of introducing advanced technology from abroad. Through careful research, the company technicians have continuously upgraded and upgraded the products, through continuous technical improvement, long-term communication and repeated experiments with technical experts at home and abroad, and finally successfully developed new ones. A generation of products.
Hollow PP Template Products Uses:
It is widely used in building engineering, bridge engineering and coal mine, etc. It mainly makes the newly poured concrete form and maintain, so that it can reach a certain strength to bear the temporary structure of self-weight and demolish the model plate.
Architectural formwork is a temporary structure, which is made according to the design requirements, so that concrete structures and components can be shaped according to the prescribed position and geometric size, maintain their correct position, and bear the weight of the building formwork and the load acting on them. The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up construction progress and reduce project cost.
The building formwork used in the construction of modern cast-in-place concrete structure is a temporary model structure to ensure that concrete structure is formed in accordance with the design requirements. It bears horizontal load (lateral pressure of concrete) and vertical load (weight of building formwork, material structure and construction load) during the construction of concrete structure.
The construction formwork structure for cast-in-situ concrete structure engineering is mainly composed of three parts: panel, supporting structure and connectors. The slab is the bearing slab directly contacting the newly poured concrete; the supporting structure is the temporary structure supporting the slab, the concrete and the construction load, which ensures the solid combination of the building formwork structure, so as not to deform and destroy; the connecting parts are the parts connecting the slab and the supporting structure into a whole.
Architectural formwork is the shell and bracket formed by concrete pouring. According to the properties of materials, it can be divided into building formwork, building wood plywood, laminated board, multi-layer board, double-sided glue, double-sided laminated building formwork, etc. Building formwork can be divided into cast-in-place concrete formwork, pre-assembled formwork, large formwork and jump formwork according to construction technology conditions.
2. Performance characteristics of formwork
Template has many advantages, such as light weight, high strength, good toughness, high impact strength, small expansion coefficient, large plate width, few joints, smooth surface, non-moisture absorption, non-mildew, non-cracking, cold resistance, high temperature resistance, acid and alkali resistance, flame retardant, sawing, nailing, welding, no need of brush demoulding agent, easy demoulding, easy assembly, high turnover rate, low price, and can be processed into any length. Point, can replace the traditional bamboo plywood, wood template: and compared with the traditional template, this product can be recycled to replace the old, turnover usage of 40 to 50 times, cheap; it is a new type of environmental protection building template to replace steel template and bamboo plywood.
At the same time, it can also be mixed with wood plywood, bamboo plywood and other materials in construction, effectively reducing construction costs and improving construction efficiency.
1. Lightweight and turnover usage can reach 50 times, and the cost is only 1/4-1/6 of wood formwork.
2. High strength, good hardness, impact resistance, wear resistance, long service life.
3. The surface is smooth and the casting effect is good.
3. Waste products can be recycled and reprocessed, and waste raw materials can be fully utilized. Compared with wood formwork and bamboo plywood, the cost of waste products is low and the cost of construction can be greatly reduced.
4. Environmental protection, energy saving, pollution-free, no toxic and harmful gas emissions.
5. Good water resistance. Long-term immersion in water does not stratify, does not soak, is not easy to deform, plate size stability; especially suitable for bridge engineering.
6. It has good toughness and can be used as various special-shaped templates for variable surface.
7. Fire-proof and flame-retardant, self-extinguishing in case of fire, high temperature resistance, non-mildew.
8. Easy demoulding, no need to brush demoulding agent, tapping the template can fall off, shorten the working hours, save manpower, and speed up the progress of the project.
9. It is acid-resistant, alkali-resistant and corrosion-resistant. It is very suitable for application in coastal areas, underground projects, mines, seawalls and dams. No anticorrosive treatment is required for use and storage, and the surface of concrete is not polluted.
10. Convenient construction, easy processing; orderable, sawable, drillable, vertical and horizontal can be arbitrarily connected and combined.
11. Installation and disassembly are convenient, fast, safe, easy to support and operate, which is conducive to the organization of construction and can effectively improve the construction progress.
