[0002] Since the rise of civil engineering, the requirements for project quality have been increasing day by day. And the permeable formwork cloth is an effective technical measure to improve the surface performance of concrete. The permeable formwork cloth, also known as a permeation-controllable concrete formwork liner, is a fiber composite that is installed on the inner side of the concrete formwork to discharge the excess water and air on the surface layer of the concrete and intercept the particles on the surface layer of the concrete. The permeable formwork cloth is generally composed of a filter layer and a permeable layer compounded together. It can greatly increase the surface density of the concrete, reduce the generation of holes, and is of great significance to the project quality.

[0003] However, the construction of the permeable formwork cloth is difficult in current project construction. Workers need to drill into the construction surface where the steel bars have been arranged to clean the steel formwork trolley, and then paste and lay the permeable formwork cloth. Manual laying has disadvantages such as uneven scraping, extremely high labor costs, time-consuming, and great difficulty in manual construction. Summary of the Invention

The first / second / third / fourth / fifth rollers are all built-in motor adjustable speed rollers, and the roller surfaces are mesh surfaces to increase friction and facilitate the driving of the permeable template cloth 4 (the built-in motor adjustable speed roller (mesh surface) adopts a mesh surface roller, only to enhance the friction and facilitate the transmission).

[0051] 2. The lower first roller 19, which is a built-in motor adjustable speed roller (gear surface), adopts: a gear-shaped surface roller (metal or polyurethane sleeve, etc. are all acceptable), only to facilitate the roller to contact the glue liquid pool to apply glue to the permeable template cloth 4.

[0052] 3. To avoid unclear images, all idler rollers include brackets and are not marked separately. Devices for supporting each part (such as: idler roller brackets, numerical control cutting knife 20, cutting knife base adapted to the numerical control cutting knife 20, glue pool, etc.) are all welded to the second outer shell 15. The fixing of the components is common knowledge for those skilled in the art, so it will not be elaborated.

[0053] It further includes a third roller 26, and the third roller 26 is arranged closely against the annular conveying member 3 for pressing the permeable template cloth 4 coated with glue on the annular conveying member 3.

[0054] As Figure 1, Figure 2 , Figure 7 and Figure 8 As shown in Figure 8 , it further includes a cyclic stripping member 21 for stripping the formwork cloth that cannot be reused from the annular conveying member 3.

[0055] The cyclic stripping member 21 includes a third housing 22, a fourth roller 23 disposed within the third housing 22, and a third roller group 24; the conveyor belt 8 of the annular conveying member 3 passes through the fourth roller 23 of the cyclic stripping member; the third roller group 24 includes two fifth rollers arranged in parallel, and a third driving gap is formed between the fifth rollers to drive the non-reusable permeable formwork cloth 4 forward.

[0056] Among them, 1. The conveyor belt 8 of the annular conveying member 3 passes through the formwork cloth conveying member 1, the gluing member 2, and the cyclic stripping member 21. Therefore, openings for the conveyor belt 8 to pass through are respectively provided on the first housing 9, the second housing 15, and the third housing 22. The opening on the first housing is as Figure 6 shown, Figure 6 The lowermost side can allow the conveyor belt to pass through. 2. The annular conveyor belt 8 adopts a relatively smooth surface conveyor belt such as PVC to ensure the smoothness of the pasting surface (facilitating removal while ensuring a certain adhesive force); the buckle of the annular conveyor belt 8 adopts a similar spiked belt buckle (which is convenient for disassembly and assembly and has good performance). 3. The first housing 9, the second housing 15, and the third housing 22 are all fixed on the frame of the steel formwork trolley 25, and the fixing methods are welding, bolt connection, etc.; the steel formwork trolley 25 moves forward to. 4. Among them, Figure 1 in which H refers to the actual laying height line of the permeable formwork cloth 4 (it only needs to be laid at a position close to the bottom of the pouring position); C refers to the top electrical layer for setting electrical equipment, and the electrical equipment is placed on the top for convenient overall replacement and inspection. D is the bottom support layer for supporting the electrical equipment. 5. Figure 7 in which, f refers to the failed permeable formwork cloth 4.

[0057] For the convenience of subsequent description, the front side of the permeable formwork cloth 4, that is, the working surface (the side in contact with the poured concrete), is named as the A side; the back side of the permeable formwork cloth 4, that is, the side pasted with the conveyor belt 8, is named as the B side.

[0058] Working principle: (1) The coiled permeable formwork fabric 4 is flattened by the template fabric conveying member 1 and then conveyed to the gluing member 2. Specifically: The first idler 10 is used to support the coiled permeable formwork fabric 4, and the one-way power arm 12 is used to limit the coiled permeable formwork fabric 4 to prevent it from running (a support shaft can also be arranged in the first housing 9 to support the coiled permeable formwork fabric 4 for easy rotation). The one-way moving force arm uses a V-shaped spring piece 13, so that the force arm can be adjusted according to the thickness of the formwork fabric and pressed tightly, and good stability can be maintained when the formwork fabric is not in use. The bottom uses the first idler 10 to ensure that the permeable formwork fabric 4 will not be damaged.

[0059] (2) The gluing member 2 applies glue to the conveyed permeable formwork fabric 4. Specifically: After the permeable formwork fabric 4 enters the second housing 15, it is guided by the third idler 16 and enters the first driving gap of the first roller group 17. The first roller 19 rotates to drive the permeable formwork fabric 4 forward. At the same time, when the first roller 19 located below rotates, the glue in the glue pool is carried on its surface. When the permeable formwork fabric 4 contacts the first roller 19, the glue can be coated on the B surface in a rolling manner.

[0060] The permeable formwork fabric 4 coated with glue enters the second gap. After entering the second gap, it is driven by the second roller group 18 towards the conveyor belt 8. The B surface of the permeable formwork fabric 4 coated with glue faces the conveyor belt 8. When the second roller group 18 conveys the permeable formwork fabric 4 coated with glue, the permeable formwork fabric 4 coated with glue is automatically pasted on the conveyor belt 8.

[0061] In this process, the permeable formwork fabric 4 coated with glue is pressed tightly on the conveyor belt 8 by the third roller 26 to improve the pasting effect between the conveyor belt 8 and the permeable formwork fabric 4.

[0062] After the permeable formwork fabric 4 is pasted on the conveyor belt 8 and covers one full circle of the conveyor belt 8, the permeable formwork fabric 4 is cut off by the numerical control cutting knife 20. Cutting can prevent repeated pasting when the permeable formwork fabric 4 is recycled, so as to avoid the situation where the permeable formwork fabric 4 is pasted to the permeable formwork fabric 4.

[0063] (3) When the permeable formwork fabric 4 is pasted on the conveyor belt 8, by tightening the conveyor belt 8 and making the conveyor belt 8 fit on the working surface of the steel form 5, it can be ensured that the permeable formwork fabric 4 fits on the working surface of the steel form 5. During pouring, the concrete contacts the permeable formwork fabric 4, thereby achieving the purpose of greatly increasing the surface density of the concrete and reducing the generation of holes.

[0064] After use, the device moves as a whole with the steel formwork trolley 25 and the steel formwork 5 to the next working station, and the installation of the next working station can be carried out. The permeable formwork cloth 4 passes through the conveyor belt 8 for half a circle, and the other half of the unused permeable formwork cloth 4 can be reattached to the surface of the steel formwork 5, so as to achieve cyclic and alternating use, avoid the single permeable formwork cloth 4 working for a long time, and improve the service life of the permeable formwork cloth 4.

[0065] (4)When the permeable formwork cloth 4 fails, manually send the joint end of the permeable formwork cloth 4 located on the conveyor belt 8 into the third driving gap of the third roller group 24. After sending it in, start the third roller group 24 and the conveyor belt 8, so as to realize the automatic peeling of the permeable formwork cloth 4. After peeling, repeat steps (1) and (2) to complete the laying of the new permeable formwork.

[0066] The present invention has the following advantages: 1. Greatly reduce the cost of manually pasting the formwork cloth. 2. Can be recycled multiple times. 3. Most of the components of the equipment are non-wearing parts. 4. The working principles of all components are simple, and the fixed positions are convenient to replace. 5. Greatly reduce the consumption of the permeable formwork cloth. 6. Increase the bonding rate of the permeable formwork cloth by using the micro-extrusion method after pasting, and can greatly reduce the operation time while ensuring the pasting effect. 7. This equipment can also be used for the laying work of geotextiles, etc., with multiple functions. 8. The electrical equipment of the equipment is placed on the top for convenient overall replacement and troubleshooting. 9. Greatly improve the application of the permeable formwork cloth in the project. 10. Improve the quality of concrete.

[0067] After pasting the permeable formwork cloth on the annular conveyor belt, the present invention tightens the annular conveyor belt and makes it closely adhere to the working surface of the steel formwork, thereby replacing the traditional manual bonding method of the permeable formwork cloth and the steel formwork, greatly simplifying the laying of the permeable formwork cloth, and there is no need to worry about problems such as uneven hanging and difficult construction during laying.

[0068] The above is only the preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields.
