Description
Protective of roof polystyrene with combination of tire waste fibers.
This invention belongs to the technical field of building materials and also is in the field of roof implementation (roofs that are made of truss and block system) of all kinds of buildings in relation to the safety and implementation of principles when using polystyrene foam blocks. Also, the use of car tire waste fibers, which have not been used before, has helped to preserve the environment more, And we can make industrial use of these materials, which have been considered as waste and harmful to nature.
Different blocks are used as fillers in the beam and block roof system Including cement, clay and polystyrene blocks that cement and clay blocks make the roofs heavy. Clay blocks have problems such as high heat transfer coefficient High weight relative to volume, lack of impact strength (very brittle(As a result, weight of the clay block makes the structure heavy. Hablex blocks also have problems, including construction industry also, the decomposition and rapid erosion of this product. due to the presence of elements and things such as lime, silica sand, cement, aluminum excessive water absorption (which is considered a major technical defect in the oxide, which when exposed to water or humidity, gradually decomposes and causes cracks or settlement in the walls of the building.
Cement blocks also have problems such as lack of durability and life in front of humidity, and the amount of their waste in transportation and also have a very high weight, which increases the dead load of the building. cement blocks are often used on building construction as building non-bearing blocks. However, the thermal insulation performance of the cement building block is poor, and the indoor heat is easily lost; in addition, the cost of the cement building block is high.
Previously, clay and cement molds were used as roof filling molds in building roofs, which were removed from the roof system over time due to the simplification of the structure and its economic issue And polystyrene blocks have problems, including the release of toxic gas during a fire .
In this invention, with this roof polystyrene blocks protective piece, we can solve the problems of using roof polystyrene blocks.
Protective piece of roof polystyrene block with a combination of car tire waste fibers which is placed under the ceiling foam blocks and on the edge of the truss joists (beams) by using polymer concrete with the combination of waste car rubber thread fibers , and reinforcement with steel wire mesh can be a suitable alternative for all old truss joist roof forms. This concrete Protective piece is produced with a height of 10 cm and a width of 50 cm and different lengths and a concrete thickness of about 1 cm with a weight of less than 5 kg) For a length of 25 cm). In this invention, There is a 6 cm thick domed seat where it rests on the edge of the beams.which can easily bear the weight of the workers during execution. In order to prevent fire, this invention can withstand fire for up to 1 hour and prevent the flame from reaching foam to prevent the release of toxic gases from polystyrene. Due to the presence of waste rubber fibers, pumice grains are well connected together with cement and it causes tensile strength to increase and load capacity to increase. Also, there is a 10 cm empty space between the concrete piece and the top foam, which acts like double-glazed glass and creates the best sound and heat insulation in the roof of the building, and completely eliminates the problem of sound transmission between floors.
The invention is mainly composed of a main building block. it has the advantages of energy conservation, environmental protection, high heat resistance, high construction speed and the like, and has a wide market in the building market . the cost is reduced, the waste utilization level is provided, the resource is saved, the environment is protected, and good economic benefits are achieved.
Protective of roof polystyrene with combination of tire waste fibers which is placed under the polystyrene blocks and placed on the edge of the beams, which, due to the use of ultra-light concrete with the combination of waste car rubber fibers and reinforcement with steel mesh, can be a suitable alternative to all old roof forms such as cement blocks and clay. In this invention, the problem of toxic gas release during the polystyrene ceiling fire has been completely solved. Also, our creation of a 10 cm empty space between the concrete piece and the top foam(polystyrene) acts like a double-paned glass and creates the best sound and heat insulation in the roof of the building, which completely eliminates the problem of sound transmission between floors.
A positive progress of the present invention is:
1)Compared with a Protective piece of roof polystyrene block with a combination of car tire waste fibers such as Polystyrene foam, due to the fact that this invention is relatively flame-retardant (even no combustion), the flame-retardant property of the utility model is good, and under the condition that the heat preservation performance of the constructed building roof reaches the standard, fire retardant performance is good, and fire caused by fire is not prone to occurring.
2) Compared with a Protective piece of roof polystyrene block with a combination of car tire waste fibers such as a cement blocks, this invention heat preservation and sound insulation performance (compared with cement blocks) is good.
3) The present invention (compared to cement building blocks) is light in weight and low in cost.
This invention having compressive strength greater than 4 MPa with a density less than 700 kg/m3 are produced.
In the past years, the use of cement block roofs increased the weight of the truss beam and blocks roof .After that, the use of polystyrene blocks was preferred over cement block roofs due to lightening. With the use of polystyrene foams, the extremely alarming problem of the occurrence and spread of toxic and dangerous gases during a fire was noticed by many building engineers, which currently many public places (schools, hospitals, mosques, clinics, etc. ) instead of using polystyrene foams, they use old and heavy cement blocks to avoid the dangers of polystyrene foams.After many studies and researches in this regard, we came to this invention Protective piece of roof polystyrene block with a combination of car tire waste fibers that in terms of weight, it is very light and in terms of strength, it is more resistant than old cement blocks and old truss beam roof forms, and in terms of safety, it is 100% safe and has solved all the problems of roof blocks .this invention is suitable for all types of truss beam roof forms that with two reinforcing poles and fibers from car tire scraps and having steel wires in the middle to increase the compressive and bending resistance and to be strong during implementation.
This invention has been able to solve the problems of toxic gassing during fire by being placed under the polystyrene foams.So that we can take advantage of the lightness of polystyrene foams without any problems . Also, by creating an empty space of 10 cm between the foam and this invention, like double-paned glass, we can achieve the best sound and heat insulation. And during execution, the execution workers can walk safely on the roof before concreting and the construction cost is reduced, and the construction progress is accelerated.
Also, the use of car tire waste fibers, which have not been used before, has helped to preserve the environment more, And we can make industrial use of these materials, which have been considered as waste and harmful to nature.
advantages of the invention include the following:
1)Very light weight compared to cement and clay blocks (weighting about 5 kg, which is lighter than all roof filler blocks in these dimensions.)
2 )Very high resistance compared to previous examples (clay blocks or cement blocks).
3)Very suitable sound insulation due to having waste rubber fibers and creating a space of 10 cm between the polystyrene foam and this invention.
4)Protection of polystyrene against heat and fire and prevention of toxic gases.
5)economic savings and reduction of construction costs.) Due to the 50% reduction in the volume of polystyrene foam(
6)High execution speed.
7)Easy of implementation compared to previous examples.
8) Compatible with environment and completely safe.
9) Less consumption of polystyrene.
10) the construction cost is reduced, and the construction progress is accelerated.
