Installation and usage instructions:
First, Use composite material hollow building formwork to intersect with 12KG weight formwork, and shear wall vertical formwork can use 14KG weight formwork.
Second, the spacing of the wood:
1. The wooden square spacing of the intersecting surface: The wooden square spacing is determined according to the thickness of the floor slab concrete. Generally, the wooden square spacing of the floor slab with a thickness less than 0.15m is 250-300mm.
2. The wooden spacing of the shear wall: the wooden spacing is adjusted according to the height and thickness of the wall. Taking the wall height of 2800mm and the wall thickness of 300mm as an example, the vertical wooden spacing of the 14mm thickness template is 100～200mm, and the thickness of 15mm is used. The wooden spacing of the formwork is 150-250mm, if the shear wall, column
When the width exceeds 1 meter, a fixed frame must be added.
3. There is no gap when the shear wall and the column formwork are assembled, and the female corner (bottom of the wall) must have a wooden square to facilitate the connection of the beam, wall and template. Shear wall vertical formwork must first be assembled into a whole block and then hoisted, and then laid flat plate, so as to reduce labor intensity and good molding effect.
4. When nailing the template, the distance from the edge of the template is 15 to 30mm. The nail strength should be moderate. The length of the nail is generally 30 to 35mm, not too long or too short.
5. The wood square of the beam bottom plate must leave a 15mm stop, and the wall panel stands on the wood square stop, so that the slurry will not leak and save the wall panel material.
Advantages of hollow plastic building templates
1. Simple support and disassembly of hollow building templates
This hollow building template is easy to support and remove. It is easy and fast to operate with a snap connection; the surface of the template is smooth and clean, it is automatically demoulded, no cleaning and maintenance, and no mold release agent is needed. The surface of the template after use is not sticky with cement, and the template does not need to be cleaned; under the same workload, the construction efficiency Comparable steel formwork increased by 40%; compared with bamboo and wood formwork, construction efficiency can be increased by 40%.
2. Short installation time of hollow building template
Under the same conditions, the horizontal formwork is laid every 1000m2 of building area, that is to say, with the same building area, the hollow energy-saving building formwork takes about 40% less time than the traditional formwork.
3. Short time for disassembly and assembly of hollow building templates
The coefficient of thermal expansion of the hollow energy-saving building template is very different from that of concrete. After the pouring is completed, the concrete will solidify with the temperature change. The template will automatically detach from the poured concrete and can be easily removed without knocking. The operation time will be greatly saved.
4. The hollow building template is convenient and safe to handle
The density of this hollow building formwork is 0.4 g/cm3, which is only 1/21 of the steel material, and the weight is light. A worker can easily take a 900 mm x 1800 mm formwork with both hands, which is very convenient to carry. The formwork will not be deformed or absorb water during use, which can greatly improve the construction safety and its damage rate is less than 1‰.
Use and product features of hollow plastic building templates:
1. Moisture resistance, strong corrosion resistance, acid and alkali resistance, rigid and plastic combination of template, high strength, light weight, high impact strength, can be sawed, planed, nailed, cold and high temperature resistant.
2. It has high strength, toughness, impact resistance, strong elasticity, and is not easy to deform, so as to greatly increase the number of circulating use of the template.
3. Light weight, complete specifications, light support and disassembly, safe and reliable construction operation and handling, low labor intensity, and high construction efficiency.
4. It can be used with various materials such as wood (bamboo) plywood at the same time.
5. After testing, the normal use times of this formwork can be used more than 50 times, which can greatly reduce the construction cost, and the used formwork can be recovered. It can be replaced with the old one, which saves more cost and benefits the development of formwork rental industry.
6. No need to apply mold release agent in the process of use, it is easy to clean and maintain, so the template cleaning and maintenance costs are reduced.
7. The surface is smooth and smooth, with good peelability from concrete and easy to demoulding, which can greatly speed up the construction progress and help to achieve clean concrete.
8. If the formwork is damaged, it can be 100% recycled, regenerated, and reduce the pollution of the waste to the environment. It is in line with the basic national policy of the country to create a conservation-oriented society. The plastic formwork has the commonality of the use of conventional building forms and more features than the conventional formwork .
