Description

Deep quantitative production device and method for FRP rib

Technical Field

The invention relates to the technical field of fiber reinforced polymer rib processing, in particular to a device and a method for quantitatively producing FRP rib depth according to displacement control.

Background

In the field of civil engineering, the reinforcing steel bar is very common to be used as a reinforcing phase in combination with matrix concrete, the addition of the reinforcing steel bar greatly improves the ultimate bearing capacity of the concrete, and the position of the reinforcing steel bar is important in the field of civil engineering. However, as resources are exhausted and the steel bars are susceptible to oxidation and corrosion, the durability and the bearing capacity of the structure are reduced, so that a novel material is urgently needed to replace the steel bars and be combined with concrete for use. Fiber Reinforced Polymer (FRP) ribs have many excellent properties, such as high strength, light weight, good corrosion resistance and fatigue resistance, and the like. The FRP reinforcement is used as a longitudinal reinforcement, a web reinforcement or a prestressed reinforcement to replace the reinforcement in the concrete, so that the durability of the concrete structure can be obviously improved, and the application prospect is good. The bonding of the FRP ribs and the concrete is the fundamental premise for ensuring that the FRP ribs and the concrete can work cooperatively. If the FRP ribs and the concrete cannot be well bonded together, the FRP ribs and the concrete cannot be coordinately deformed under the condition of small deformation after the concrete member is deformed under stress; in case of large deformation, the FRP ribs are not well anchored in the concrete structure, and thus relative slippage occurs and damage occurs. The bonding strength between the FRP ribs and the concrete is related to the rib depth of the surfaces of the FRP ribs and the quality of the concrete, wherein the rib depth of the surfaces of the FRP ribs is particularly obvious. The bond between the FRP rib with the rib and the concrete consists of three parts of chemical adhesive force, frictional resistance and mechanical biting force. The concrete is embedded into the rib depth of the FRP rib and is occluded with the rib depth, so that the bonding performance between the FRP rib and the concrete can be obviously improved.

However, the existing FRP rib winding rib production device can not carry out quantitative control on the rib depth, and only can produce FRP rib types with shallow ribs or deep ribs. If the finished FRP rib is a shallow rib, the strength of the FRP rib cannot be weakened to a great extent, but the bonding strength between the FRP rib and concrete can be greatly influenced; if the deep ribs are adopted, the bonding strength between the deep ribs and concrete is not influenced, but the strength of the FRP ribs is weakened to a great extent. In order to solve the problems, the FRP rib is tried to be found out on the premise that the strength of the FRP rib is extremely weakened, and the rib depth can be stressed with concrete in a coordinated mode, so that the maximum bonding performance of the FRP rib and the concrete is achieved.

The embodiment of the invention provides a deep quantitative production device for FRP ribs, as shown in figures 1-5, comprising: the winding mechanism 1 is sleeved on the FRP rib and used for driving the winding belt to rotate around the FRP rib, so that the winding belt is wound on the FRP rib which moves forwards; the traction mechanism 2 is fixed with the winding mechanism 1 and used for winding belt traction; the traction mechanism 2 includes: a support frame fixed with the winding mechanism 1, and a tractor 23 fixed on the support frame; the support frame is further provided with a winding belt spool 21 and upper and lower idler wheels 24, the traction machine 23 drives the upper and lower idler wheels 24 to rotate, a winding belt on the winding belt spool 21 penetrates through a gap between the upper and lower idler wheels 24, and the traction machine 23 drives the winding belt to advance.

As an apparatus for deeply producing FRP ribs in the embodiment of the present invention, further, as shown in fig. 2, the winding mechanism 1 includes a winding wheel 11 sleeved on the FRP ribs, a driving motor for driving the winding wheel 11 to rotate, and a guide rod 12 for guiding an advancing winding belt; the guide rod 12 is arranged on the winding wheel 11 and is consistent with the forward advancing direction of the FRP rib. The rotating speed of the driving motor can be determined through the target rib spacing and the advancing traction speed of the FRP ribs so as to meet the requirement of rib depth quantitative production. Further, as shown in fig. 5, the guide bar 12 is provided with an adjustment hole for passing a wrapping tape therethrough. The rigidity round rod can be selected, the size of the orifice can be controlled to be 5mm multiplied by 50mm according to needs, and the depth of the target rib can be automatically adjusted according to the angle change of the winding belt in the orifice when the depth of the rib is different.

As an apparatus for deeply producing FRP ribs in the embodiment of the present invention, as shown in fig. 4, front and rear centering rods are further disposed on the supporting frames at two sides of the upper and lower rollers 24, the front and rear centering rods are respectively provided with centering holes for passing a winding belt, and the centers of the centering holes and the horizontal center of the gap between the upper and lower rollers 24 are on the same straight line. The winding belt yarn group penetrates through the winding belt spool 21, the led-out winding belt sequentially penetrates through the front centering hole, the upper and lower rollers 24 and the rear centering hole, the front centering hole, the upper and lower rollers 24 and the rear centering hole are on the same straight line, and stable and reliable operation is achieved when traction of the winding belt is improved. The upper and lower rollers 24 can be selected from rigid bodies which are extruded and not easy to deform, the centering rod can be selected from rigid rods with holes in the middle, the size of the hole opening can be determined according to the thickness and width of a used winding belt, the size of the hole opening can be determined to be 2mm multiplied by 4mm according to the size of a common winding belt, and the centroid connecting line of the front centering hole and the rear centering hole is required to be coincided with the middle cross section of the upper and lower rollers 24. Furthermore, a wear-resistant layer is arranged on the centering hole, so that friction between the winding belt and the hole body is reduced.

As the FRP rib deep quantization production device in the embodiment of the invention, further, the wear-resistant layer is a paint-plated cambered surface of the hole and/or a rubber wrapping layer. The wear-resistant layer function on the hole can be realized by designing the hole into a smooth arc surface, or plating baking varnish, or wrapping a rubber sleeve on the surface or replacing the middle opening part with hard plastics, so as to reduce friction and damage in the advancing process of the winding belt.

As the FRP rib deep quantization production device in the embodiment of the invention, furthermore, the upper and lower rollers 24 are arranged on the support frame through rotating shafts, the output end of the tractor 23 is connected with the upper roller rotating shaft, and the upper roller rotating shaft is connected with the lower roller rotating shaft through the driving of the gear 27. Further, the support frame is provided with a pressure bolt 26 for adjusting the relative height of the upper roller rotating shaft and the lower roller rotating shaft, and the gap between the upper roller 24 and the lower roller 24 is adjusted by screwing the pressure bolt 26. The pressure bolt 26 is screwed clockwise to push the rotation shaft of the upper roller downwards, so that the upper roller is tightly extruded with the lower roller, the winding belt passing through the middle of the two rollers is fixed firmly, and the winding belt is prevented from being pulled out abnormally. When the operation of the traction machine 23 is stopped, the upper and lower rollers 24 can be firmly held in a stationary state by the locking function of the traction machine 23 itself and the stopped state of the gear 27.

Further, based on the above apparatus, an embodiment of the present invention further provides a deep quantitative production method for FRP ribs, which specifically includes the following steps: intercepting a single winding rib interface to obtain the rib depth; calculating the length of a single spiral winding rib according to the rib spacing, the rib depth and the FRP rib diameter; calculating the traction length of the winding belt in unit time according to the rotating speed of the winding mechanism 1 and the length of the single winding rib spiral line; the cooperative working parameters of the tractor 23 are set through the traction length of the winding belt and the circumference of the roller in unit time, and the FRP rib depth is quantitatively produced through displacement control. Under the condition of determining the diameter, the space and the depth of the FRP ribs and the parameters of the FRP rib traction device, the quantitative production of determining the depth of the FRP ribs by adjusting the parameters of the winding belt tractor 23 to change the winding belt outlet speed is realized.

When the FRP rib quantized rib depth is produced by controlling the winding belt outgoing line length through displacement, a winding belt filament group (carbon fiber belt) required for winding is installed on the winding belt spool 21. The tape is passed through the front centering hole, passed between the upper and lower rollers 24, and then drawn out through the rear centering hole, which ensures that the tape travels in a straight line between the three. The winding belt passes through the centering hole and then passes through the strip-shaped hole in the middle of the guide rod 12. The tightening and winding belt is firmly tied on the FRP ribs which advance forwards. The winding pressure bolt 26 is screwed clockwise to push the two ends of the upper roller to move downwards, so that the upper roller and the lower roller are tightly pressed together to generate a certain pre-pressure, the upper gear 27 and the lower gear 27 are meshed with each other, the synchronous stop and synchronization adjustment of the upper roller and the lower roller 24 are realized, and a large pulling force is applied in the direction of the guide rod 12 under the condition that the winding belt tractor 23 stops working or operates at a set rotating speed, so that the winding belt cannot be easily pulled out from the winding belt spool 21. According to the requirements of different rib depths, calculated winding belt tractor 23 cooperative working parameters are input, and other parameters in the production process are matched to produce the FRP ribs with quantized rib depths.

As shown in fig. 6, analysis was performed by cutting out the individual winding ribs, and assuming that the rib pitch of the individual winding ribs was L, cutting and stretching along the upper edges thereof resulted in the dimensions shown on the right of the lower drawing. When the rib depth is H, the length of the helix within a single winding rib is:

d is the diameter of the FRP rib

According to the above formula, it can be determined that the length of the winding tape required in a single rib pitch is different when the rib depths are different, and then the outgoing length of the winding tape per unit time is S' × N. The length of the inner spiral line of the single rib space is calculated and multiplied by the rotating speed N rad/min of the driving motor of the winding belt winding wheel 11, so that the outgoing line length of the winding belt in unit time can be obtained, and the outgoing line length of the winding belt in unit time is divided by the circumference of the roller 24, so that the cooperative working parameter N rad/min of the winding belt tractor 23 can be obtained. N may be determined based on the target parameter. The winding belt can be a high-strength carbon fiber belt or a high-strength synthetic polymer belt, has large strength and high elastic modulus, and is not easy to deform and break in the stretching process.

To verify the effectiveness of the apparatus and method of the present invention, the following is further illustrated with reference to specific examples:

a batch of CFRP ribs are produced, and the target parameters are as follows: the diameter D of the FRP rib is 10mm, the rib spacing L is 1.5 times of the diameter of the FRP rib, the rib depth H is 6 percent of the diameter of the FRP rib, the diameter of the upper and lower rollers 24 in the winding belt traction mechanism 2 is R is 30mm, and the forward advancing speed of the FRP rib during production can be determined to be V is 400mm/min according to the physicochemical characteristics of the matrix resin.

The cooperative operating parameters of the wrap tape tractor 23 may be calculated by the following process: the known rib spacing L is 1.5 times the FRP rib diameter, D is 10mm, and L is 15 mm; the rib depth H is 6% of the FRP rib diameter, and can be 0.6 mm.

1) From the knowledge it follows: when the rib depth H is 0.6mm, the length of the inner spiral line between the single ribs

2) As is known, when producing an FRP rib, the forward speed is V400 mm/min, and the rib pitch L is 15mm, and the rotation speed of the winding mechanism 1 is:

it shows that within one minute of forward travel of the FRP ribs, the number of winding ribs formed is approximately 26.7, and the length of the winding belt output by the upper and lower rollers 24 driven by the winding belt traction machine 23 within one minute is:

X＝S′×N＝31.44×26.7＝839.5mm/min

3) when the diameter R of the upper and lower rollers 24 is 30mm, the length of the winding belt output by one rotation of the rollers is:

x＝πR＝3.14×30＝94.2mm

the co-operating parameter of the wrap-around belt traction machine 23, i.e. the rotational speed, is then

The rotation speed n, which is a cooperative operating parameter of the wrapping tape tractor 23, is input to the equipment console.

The practical case is as follows:

case one:

the design device is used for carrying out quantitative production of CFRP rib depth, and the feasibility of the design scheme of the device is verified. The target parameters are as follows: the diameter D of the CFRP rib is 10mm, the rib spacing L is 1.5 times of the diameter of the CFRP rib, the rib depth H is 6 percent of the diameter of the FRP rib, the diameter of an upper roller 24 and a lower roller 24 in the winding belt traction mechanism 2 is 30mm, and the forward advancing speed V of the CFRP rib during production can be determined to be 400mm/min according to the physicochemical characteristics of matrix resin. The results of the previous examples show that: the input parameter of the wrap belt tractor 23 is 8.9 rad/min. Five rib depths are randomly selected from the CFRP bars of the finished products in the same batch, and the rib depth H is measured by a vernier caliper after the winding belt is stripped, and the obtained measurement results are shown in the following table:

it can be seen from the data in the above table that the quantification of rib depth is also desirable, with the test rib depth floating above and below the target rib depth, partly because the wrap tape may be pulled away or a small amount of resin left behind when peeled from the CFRP bar.

Case two:

the design device is used for carrying out the quantitative production of the rib depth of the hybrid FRP ribs (formed by mixing the glass fibers and the carbon fibers), and the feasibility of the design scheme of the device is verified. The target parameters are as follows: the diameter D of the hybrid FRP rib is 18mm, the rib spacing L is 1 time of the diameter of the hybrid FRP rib, the rib depth H is 10 percent of the diameter of the FRP rib, the diameter of the upper and lower rollers 24 in the winding belt traction mechanism 2 is 30mm, and the forward advancing speed of the FRP rib during production can be determined to be 380mm/min according to the physicochemical characteristics of the matrix resin. The calculation method of the previous embodiment shows that: the input parameter of the wrap belt tractor 23 is 10.9 rad/min. Five of the mixed FRP ribs of the finished products in the same batch are randomly selected, and after the winding belt is stripped, the rib depth H is measured by a vernier caliper, and the obtained measurement results are shown in the following table:

as can be seen from the data in the table above, when producing FRP ribs with larger rib depths, the quantification result is also more accurate, the test result fluctuates up and down in the target result, and the partial reasons causing the phenomenon may be that a small amount of resin may be taken away or left when the winding belt is stripped from the mixed FRP ribs, and a thin layer of carbon black is left in the carbon fiber winding belt.

Case three:

the design device is used for quantitative production of GFRP rib depth, and feasibility of the design scheme of the device is verified. The target parameters are as follows: the diameter D of the GFRP rib is 24mm, the rib spacing L is 1.5 times of the diameter of the GFRP rib, the rib depth H is 15% of the diameter of the GFRP rib, the diameter R of an upper roller 24 and a lower roller 24 in the winding belt traction mechanism 2 is 30mm, and the forward advancing speed V of the GFRP rib during production can be determined to be 320mm/min according to the physicochemical characteristics of matrix resin. The results of the previous examples show that: the input parameter of the wrap belt tractor 23 is 7.3 rad/min. Five rib depths are randomly selected from the GFRP bars of the finished products in the same batch, and the rib depth H is measured by a vernier caliper after the winding belt is stripped, and the obtained measurement results are shown in the following table:

from the data in the table, it can be seen that, when producing a large rib deep FRP bar, the quantification result is relatively accurate, and the tested rib depths are all smaller than the target rib depths, and the reason for this phenomenon is that when the rib depths are larger, the tensile force applied to the winding belt becomes larger to generate deformation and elongation, and on the other hand, the reason is that a thin carbon fiber winding belt may be left when the winding belt is peeled off from the GFRP bar.
