Description

Device for quantitatively producing FRP rib depth according to displacement control

Technical Field

The utility model relates to a fibre reinforced polymer muscle processing technology field, in particular to quantify the dark device of production FRP muscle rib 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.

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.

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.

Referring to FIG. 6, a single winding rib interface is cut 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. By using the device in the embodiment of the scheme, under the condition of determining the diameter, the space between the ribs, the depth of the ribs and the parameters of the FRP rib traction device, the quantitative production of the depth of the FRP rib ribs can be determined by adjusting the parameters of the winding belt tractor 23 to change the winding belt outlet speed.

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.

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:

s' is equal to [ pi (D-2H)]²And L²The square root of the sum of the two, wherein 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.
