Description

Technical Field

[0001] This invention relates to the field of building equipment technology, and in particular to an FRP mesh fabrication device. Background Technology

[0002] With the rapid development of my country's economy, higher demands have been placed on the construction industry. However, the wall materials used in my country's construction industry still rely on traditional clay bricks and tiles, resulting in the waste of precious land resources and environmental pollution during the firing process. Furthermore, in actual use, this presents numerous insurmountable difficulties regarding the functionality, earthquake resistance, and construction techniques of buildings.

[0003] In response to the aforementioned problems, the Ministry of Construction proposed a policy for reforming wall materials, leading to the emergence of numerous new building materials. Among them, autoclaved aerated concrete (AAC) interior wall panels are highly favored due to their advantages such as light weight, low density, high strength, and corrosion resistance. AAC interior wall panels are cast using molds, and to increase their resistance to bending, compression, and tension, the panels contain internal steel mesh reinforcement. This mesh reinforcement consists of horizontal and vertical bars arranged in sequence and welded together using electric welding equipment. However, AAC panels are porous and absorbent materials, making the steel mesh reinforcement highly susceptible to corrosion, which can cause the wall panels to crack and hinder their widespread use. While FRP (fiberglass reinforced plastic) reinforcement can solve the problem of steel corrosion, it cannot be mechanically produced using welding machines. Although it can be tied manually or mechanically, this poses significant challenges for AAC wall panels.

[0004] 1. Because autoclaved aerated concrete requires long-term steam curing under high temperature and high pressure with saturated water vapor, the binding steel wires may corrode and break, affecting the performance.

[0005] 2. Due to the limited number of binding points on the mesh and the thin diameter of the FRP reinforcement used, the binding quality is difficult to guarantee, resulting in large deformation of the mesh, which affects production and use, and greatly reduces the holding capacity of the reinforcing ribs.

[0006] 3. In engineering, the main stress mode of wall panels is bending resistance. The presence of distribution reinforcement (longitudinal) will greatly improve the bending resistance of the wall panels. However, due to the binding of the longitudinal and transverse intersections, the quality of the binding points is difficult to control, the effect of the distribution reinforcement is reduced, and when subjected to external forces, it is easy to cause excessive displacement of the transverse reinforcement, thereby significantly reducing the bending resistance of the wall panels.

[0007] Therefore, this invention proposes an FRP mesh fabrication equipment that can automatically manufacture FRP mesh, automatically bind the horizontal and vertical ribs, and impregnate or inject resin glue at the binding position after binding to further strengthen the connection strength between the horizontal and vertical ribs, forming a true mesh structure. At the same time, because the binding wires are wrapped with resin, the equipment solves the problem of FRP mesh fabrication equipment that prevents the binding wires from rusting. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing an FRP mesh fabrication device.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An FRP mesh fabrication device includes an FRP reinforcement conveying device, a binding and bonding device, and an automatic cutting device arranged in sequence.

[0011] The FRP rebar conveying device synchronously conveys the FRP rebar forward, feeding it along the conveying guide rail into the binding and bonding device according to design requirements.

[0012] The binding and bonding device is used to bind and bond the transverse FRP bars and the longitudinal FRP bars.

[0013] The automatic cutting device is used to cut the bonded FRP mesh.

[0014] Furthermore, the binding and bonding device is equipped with a binding frame, which is slidably disposed inside the binding and bonding device. The binding frame is equipped with a binding device corresponding to the transverse FRP ribs. Directly below the binding device, there is a transverse rib positioning groove and a longitudinal rib positioning component, which are used to limit the position of the transverse and longitudinal ribs. The transverse and longitudinal ribs form a cross at the bottom of the binding device. Binding space is left above and below the cross ribs to allow the binding device output port to move up and down through the cross point to complete the binding action.

[0015] Furthermore, the binding and bonding device is provided with an adhesive frame, which is slidably disposed inside the binding and bonding device. The adhesive frame is provided with a pressure block corresponding to the transverse FRP bar. A bonding platform is provided directly below the pressure block. The bonding platform is provided with a glue groove corresponding to the pressure block. A partition strip is provided in the glue groove for supporting the longitudinal FRP bar. The cavity of the glue groove contains glue.

[0016] Furthermore, the glue tank is equipped with a dividing device on its flat opening, with dividing strips located on both sides of the pressing block to ensure that the glue is pressed into the glue at the cross intersection.

[0017] Furthermore, the binding and bonding device is equipped with a storage chamber for longitudinal FRP ribs, and the bottom of the storage chamber is provided with a discharge port, which can release single longitudinal FRP ribs at intervals.

[0018] Furthermore, the FRP rebar conveying device is also provided with an FRP rebar insertion device on the side away from the binding and bonding device. The FRP rebar insertion device is used to control the straightness of the FRP and the insertion spacing of adjacent FRP rebars.

[0019] Furthermore, a drying and curing chamber is provided between the binding and bonding device and the automatic cutting device. The drying and curing chamber is equipped with a heating or ultraviolet device to quickly cure the resin at the junction, so that the longitudinal and transverse ribs at the connection point are firmly bonded together.

[0020] Furthermore, the FRP reinforcement conveying device consists of two sets, respectively located on both sides of the feed buffer ring, and transverse FRP reinforcement conveying tracks are provided at both the front and rear of the FRP conveying device.

[0021] Furthermore, the FRP reinforcement conveying track is adjustable on the frame of the FRP reinforcement conveying device to adjust the number and spacing of transverse FRP reinforcements.

[0022] An FRP mesh fabrication method, utilizing the aforementioned FRP mesh fabrication equipment, includes the following steps:

[0023] S1: Prepare longitudinal and transverse FRP bars according to design requirements;

[0024] S2: The transverse FRP reinforcement is laid horizontally through the conveying guide rail;

[0025] S3: Place the longitudinal FRP bars horizontally inside the storage compartment, release the storage compartment one bar at a time, and form a cross with the transverse FRP bars;

[0026] S4: Start the strapping frame to move downwards, so that the strapping device is aligned with the cross intersection formed by the horizontal FRP ribs and the vertical FRP ribs, and strap the intersection to form an FRP rib mesh.

[0027] S5: Advance the FRP mesh one module position forward so that the binding position moves above the glue tank 14, activate the bonding frame so that the pressure block presses the cross intersection into the glue tank, and the cross gap is immersed in resin.

[0028] S6: The mesh moves into the drying and curing chamber to complete the resin curing process;

[0029] S7: After the resin has solidified, the hook puller continues to pull the FRP mesh to the next mold position until the mesh reaches the design size. The automatic cutting device then cuts the FRP mesh.

[0030] Beneficial effects

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the design of the present invention, an FRP mesh manufacturing equipment is proposed that can realize the automated production of FRP mesh, automatically bind the horizontal and vertical ribs, inject resin glue at the binding position after binding, and solidify it into a whole, further strengthening the connection strength between the horizontal and vertical ribs, while solving the problem of rust on the binding wire.

[0041] Reference Figures 1-5 An FRP mesh manufacturing device includes an FRP reinforcement conveying device, a binding and bonding device 3 and an automatic cutting device 5 arranged in sequence.

[0042] The FRP rebar conveying device conveys FRP rebar into the binding and bonding device 3 via a conveying guide rail. The automatic conveying device is a combination of a drive shaft and a pressure roller (shaft).

[0043] The binding and bonding device 3 is used to bind and bond the transverse FRP bars and the longitudinal FRP bars;

[0044] The automatic cutting device 5 is used to cut the bonded FRP mesh.

[0045] In other preferred embodiments, a binding frame 8 is provided inside the binding and bonding device 3. The binding frame 8 is slidably disposed inside the binding and bonding device. A binding device 10 corresponding to the transverse FRP reinforcement is provided on the binding frame 8. A transverse reinforcement positioning groove 9 and a longitudinal reinforcement positioning component 11 are provided directly below the binding device 10. A binding space is formed between the transverse reinforcement positioning groove 9 and the longitudinal reinforcement positioning component 11 for the binding device 10 to move up and down to ensure the binding of the cross reinforcements.

[0046] Specifically, gaps are left above and below the intersection of the transverse and longitudinal FRP ribs to form a binding space. A binding device 10 is installed above the binding space and is suspended on the binding frame 8. The binding frame 8 is slidably connected to the inner wall of the outer shell of the binding and bonding device 3. When in use, the binding frame 8 is moved down so that the output binding wire of the binding device 10 passes through the intersection of the transverse and longitudinal FRP ribs and binds the longitudinal and transverse ribs together.

[0047] In other preferred embodiments, the binding and bonding device 3 is provided with an adhesive frame 7, which is slidably disposed inside the binding and bonding device. The adhesive frame 7 is provided with a pressure block 12 corresponding to the transverse FRP bar. A bonding platform 15 is provided directly below the pressure block 12. The bonding platform 15 is provided with a glue groove 14 corresponding to the pressure block 12. The glue groove 14 is used to hold the glue and is designed to be continuous.

[0048] Specifically, the glue tank has a partition strip on its flat opening. The partition strip is located on both sides of the pressure block to support the non-cross-intersection parts of the longitudinal ribs, preventing them from entering the glue tank. The bonding platform 15 is located on the discharge side of the bundling platform. During operation, the pressure block 12 is used to press the cross-intersection of the bundled mesh into the glue tank 14. Since the pressure block 12 is suspended on the bonding frame 7, the glue impregnation action at the cross-intersection of the FRP ribs can be completed by lowering the bonding frame 7.

[0049] Preferably, the pressure block 12 can be replaced by a glue gun, which has one or more inclined glue inlets 13, which inject the corresponding resin glue into the intersection (in this case, the glue groove under the pressure block can be omitted).

[0050] In other preferred embodiments, the binding and bonding device 3 is provided with a storage bin for longitudinal FRP ribs. The storage bin has a discharge port at its bottom, allowing for the release of individual longitudinal FRP ribs at intervals. Each released longitudinal rib is intercepted by the edge of the longitudinal rib positioning component 11 and falls into it, forming a cross structure with the transverse ribs in the transverse rib positioning groove, facilitating subsequent binding operations. The storage bin can release individual FRP ribs by gravity or via a rotary table.

[0051] In other preferred embodiments, the longitudinal reinforcement can be delivered by setting a single reinforcement continuous delivery device and a cutting device on the side of the binding device, cutting the single reinforcement and letting it fall into the longitudinal reinforcement release point, and releasing the single reinforcement to the longitudinal reinforcement limit point.

[0052] In other preferred embodiments, an FRP rebar insertion device 1 is also provided on the side of the FRP rebar conveying device away from the binding and bonding device 3. The FRP rebar insertion device 1 is used to control the insertion spacing of the FRP rebar and adjacent FRP rebars.

[0053] Preferably, the output end of the FRP bar insertion device has a conveying track;

[0054] In other preferred embodiments, a drying and curing box 4 is also provided between the binding and bonding device 3 and the automatic cutting device 5. The drying and curing box 4 is used to quickly cure the resin at the junction, so that the longitudinal and transverse ribs at the connection point are firmly bonded together. Specifically, the drying and curing box 4 is located behind the adhesive platform. When the mesh after being soaked in resin passes through the drying box, the resin is cured at high temperature to firmly bond the longitudinal and transverse ribs together. At the same time, the resin completely wraps the binding wire, solving the problem of rust on the binding wire.

[0055] Preferably, the curing chamber can use ultraviolet light to irradiate the resin to achieve the curing effect.

[0056] In other preferred embodiments, the FRP reinforcement conveying device 2 consists of two sets, respectively located on both sides of the feed buffer ring 6. Transverse FRP reinforcement conveying tracks are provided at the front and rear of the FRP conveying device. The conveying tracks can be made of steel pipes, grooves, or pressure rollers.

[0057] In other preferred embodiments, the binding and bonding device can move back and forth to achieve binding and bonding without moving the FRP reinforcement.

[0058] In other preferred embodiments, the conveying device at the front end of the bundling device is not used. The transverse FRP is bundled and bonded, and then the motor drives the traction mesh forward. The motor is program-controlled to control the mesh forward and simultaneously complete the longitudinal rib conveying, thus completing the continuous production of the mesh.

[0059] In other preferred embodiments, the FRP reinforcement conveying track is adjustablely mounted on the frame of the FRP reinforcement conveying device 2 to adjust the spacing of the transverse FRP reinforcements.

[0060] A method for preparing FRP mesh utilizes the aforementioned preparation equipment and includes the following steps:

[0061] S1: Prepare longitudinal and transverse FRP bars according to design requirements;

[0062] S2: The transverse FRP reinforcement is laid horizontally through the conveying guide rail;

[0063] S3: Place the longitudinal FRP bars horizontally inside the storage compartment, release the storage compartment one bar at a time, and form a cross with the transverse FRP bars;

[0064] S4: Start the strapping frame 8 to move downwards, so that the strapping device 10 is aligned with the cross intersection formed by the transverse FRP ribs and the longitudinal FRP ribs, and strap the intersection to form an FRP rib mesh.

[0065] S5: Advance the FRP mesh one mold position forward so that the binding position moves above the glue tank 14, activate the first bonding frame 7, so that the pressure block 12 presses the cross intersection into the glue tank 14, and the cross gap is immersed in resin.

[0066] S6: The mesh moves into the drying and curing chamber in section 4 to complete the resin curing process;

[0067] S7: After the resin has solidified, the hook puller continues to pull the FRP mesh to the next mold position until the mesh reaches the design size. The cutting machine then cuts the FRP mesh.

[0068] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
