Description

Structure and method of hollow plastic formwork

The present invention provides a structure and a method for a hollow plastic mold, especially a kind of convenient feeding, accurate and uniform feeding, stable and non-deformation, and at the same time, it has the effects of flame retardant, heat insulation, sound insulation, water resistance, and recyclability, and also The structure and method of the hollow plastic formwork can prevent the cement slurry from flowing into the interior of the formwork body, thereby preventing the breeding of insects and molds.

According to the press, during the construction of cement buildings, a construction method commonly known as grouting is often used to form beams, columns or walls, etc. When grouting, it is necessary to use conventional formwork to surround a space, and inject cement slurry into this space. Wait for it to dry and solidify, and then remove the conventional formwork (commonly known as demolding) to expose the solidified beams, columns or walls.

Common formwork can be divided into wooden formwork, iron formwork and plastic formwork according to the material. Among them, the board mold will absorb water, and the surface will be rough and uneven due to factors such as water absorption or joints, which requires an additional leveling process, so it cannot be recycled and reused. The environmental protection is poor, and the cost is difficult to reduce; the iron formwork is heavy in weight, which is not conducive to handling and construction, and it is difficult to process according to the needs of the construction site, so it is only suitable for the situation where the site is wide or there is a load-bearing requirement, not suitable for General construction, therefore, today's construction industry has gradually tended to use plastic formwork for operations.

However, when the above conventional plastic formwork is used, there are the following problems and shortcomings that need to be improved:

First, the design of a single feeding port is not conducive to the addition of multiple raw materials.

Second, the design of a single stirring device cannot uniformly mix and stir a variety of raw materials.

Third, the conventional hollow plastic formwork is easy to cause problems such as blockage and weight increase due to the inflow of cement slurry into the hollow structure.

Fourth, if the conventional hollow plastic mold is splashed by water, it is easy to breed ants, Termites and other insects and fungi.

Fifth, when the cement slurry is poured, the mold will form thermal expansion and contraction due to the high temperature of the cement slurry, which will cause deformation and affect the cooling and forming of the cement slurry.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the applicant of the present invention and related manufacturers in the industry are eager to research and improve.

From the above structure and steps, it is known that the user first puts the polypropylene 101 into the first screw mixer 31, and at the same time puts the stone powder 102 into the second screw mixer 32, so as to be heated, melted and stirred respectively (as shown in Fig. 6). shown), at this time, it can be clearly seen from the figure that the first screw mixer 31 and the second screw mixer 32 are connected to one end away from the feeding port. Therefore, the melted and stirred polypropylene 101 and stone powder 102 will be respectively A screw mixer 31 and a second screw mixer 32 enter the third screw mixer 33, and through the third screw mixer 33, the polypropylene 101 and the stone powder 102 can be mixed, and after mixing, the heating and stirring actions are performed again to Make the polypropylene 101 and the stone powder 102 evenly distributed.

Next, pour the flame retardant 103 and the strengthening agent 104 into the solvent feeding device 34 at the same time (as shown in the seventh figure, the solvent feeding device 34 in this embodiment is an example of a hydraulic device), and the solvent feeding device 34 will hydraulically transport the flame retardant 103 and the strengthening agent 104 into the third screw mixer 33, so that the flame retardant 103 and the strengthening agent 104 transported by the solvent feeding device 34 will be different from the The polypropylene 101 and the stone powder 102 in the third screw mixer 33 are mixed, and finally heated and stirred to form a final batch.

Then, the finished material is transported into the mesh forming machine 4 by the third screw mixer 33, so as to The finished material is extruded and formed (as shown in the eighth figure), and then the formed material is fed into the cooling device 5 to cool and set, which becomes the die body 1 of the present invention, and by the design of the mesh forming machine 4, That is, the above-mentioned communicating groove 11 can be formed in the die body 1 . Finally, the post-processing of the formwork body 1 is carried out, so that the plaster bonding surface 21 of the waterproof plaster 2 is combined with the first plane portion 12 and the second plane portion 13 on both sides of the formwork body 1 (as shown in the ninth figure), By closing the opening 111 , the manufacturing operation of the die body 1 of the present invention is completed.

The formwork body 1 of the present invention can not only be used in building construction according to conventional methods, but also can be made into a roof (as shown in the tenth figure) or a bed board (as shown in the eleventh figure). The die body 1 has polypropylene 101, stone powder 102, flame retardant 103, and reinforcing agent 104, so it has a certain elasticity and can be properly bent. When several die bodies are made of PP adhesive After bonding with each other, it can be used as a roof. If polyurea super glue is sprayed on the surface of the formwork body 1, the formwork body 1 can be durable and not deformed, thereby making the present invention a low-cost and durable green Eco-friendly roof. In addition, the use of the formwork body 1 as a bed board can also achieve the effect of environmental protection.

When the user uses the formwork body 1b of the present invention for building construction, the design of the striped surface on the formwork body 1b can be matched, so that the solidified cement surface presents a striped state, thereby facilitating the subsequent operation of tiling. Improve the overall practicality.

When the formwork body 1b of the present invention is used in a place with good environment such as dry air and good ventilation, there is no need to apply waterproof gypsum, thereby saving manufacturing cost and time required for manufacturing.

Please also refer to Figure 14, which is a three-dimensional view of another preferred embodiment of the present invention. When the above-mentioned components are used, it can be clearly seen from the figure that the present embodiment is the same as the above-mentioned still another preferred embodiment. The embodiments are similar with minor differences, except that in this embodiment, the formwork body 1c contains a stabilizer 105c, and at least one reinforcing edge 14c is formed on both sides of the formwork body 1c.

As described in another preferred embodiment above, after adding the stabilizer 105c to the formwork body 1c, the bonding strength of the polypropylene 101c, the stone powder 102c, the flame retardant 103c, and the reinforcing agent 104c can be improved, so that the overall structure is more Stable and viscous. When using the formwork body 1c, the sides are often damaged due to handling. Therefore, through the design of the reinforcing side 14c, the grooves are connected to each other. 11c was damaged, and at the same time, the overall structural strength was improved.

Therefore, the configuration of this embodiment can achieve the effects of saving manufacturing cost, reducing manufacturing time, and improving structural strength at the same time.

However, the above descriptions are only the preferred embodiments of the present invention, which do not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the contents of the description and drawings of the present invention should be the same.
