Description

Technical Field

[0001] The present invention belongs to the technical field of wind power, and in particular, relates to a prefabricated assembly structure of a concrete tower for wind power and an assembly method of a concrete tower for wind power based on the prefabricated assembly structure. Background Art

[0002] The wind turbine tower is an important supporting structure in the wind power system. Its upper part is connected to the wind turbine generator set, and its lower part is connected to the foundation. When the wind turbine generator set is working, the wind turbine tower has to bear the dynamic bending and torsion caused by wind loads and various vibrations, and fatigue problems are prominent. At present, in order to ensure the safe and stable operation of wind turbine generator sets, wind turbine towers often use all-steel towers. However, with the continuous increase in the capacity of a single unit, the thickness and diameter of the tower itself continue to increase, causing many problems in production, transportation, maintenance, etc., which seriously restricts the development of high-power wind turbine generator sets.

[0003] For this reason, prefabricated assembled towers came into being. According to the material, prefabricated assembled towers can be divided into steel towers, concrete towers and steel-concrete mixed towers. Among them, prefabricated assembled concrete towers make full use of the advantages of concrete being easy to obtain locally, mature manufacturing technology and low maintenance costs. Most of the current prefabricated assembled concrete towers are assembled in sections and pieces. The so-called piece-by-piece assembly means that each section of the concrete tower is assembled from multiple pieces of prefabricated concrete components. Single-piece concrete components are light in weight, small in size and easy to transport.

[0004] In order to ensure the construction quality of the piece-by-piece tower, each prefabricated concrete component is usually hoisted and positioned, and then the joints of adjacent prefabricated components are sealed with rapid-hardening cement, and then the adjacent prefabricated components are connected by high-pressure grouting. After the grouting material hardens, the tower section is formed. In the above process, the prefabricated components require precise positioning, resulting in low hoisting construction efficiency; the rapid-hardening cement used for sealing the joints shrinks greatly and is prone to cracking, which can easily lead to grouting leakage during construction and peeling off during operation to form high-altitude falling objects; in order to accommodate the defects of the sealing material, the grouting height during high-pressure grouting is often limited, and grouting must be done in batches, affecting the grouting construction efficiency.

[0005] Therefore, how to solve the difficulties in positioning, sealing and grouting of wind power concrete towers during assembly has become a technical problem that technicians in this field need to solve urgently. Summary of the invention

[0006] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a prefabricated assembly structure of concrete tower for wind power generation. The prefabricated assembly structure improves the accuracy of assembly positioning and construction efficiency by setting prestress, avoids leakage and falling objects from high altitude by elastic clips, and combines the advantages of prestress and elastic clip sealing to achieve one-time grouting, thereby improving the construction efficiency of prefabricated assembly of concrete tower for wind power generation.

[0007] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solution:

[0008] A prefabricated structure of a concrete tower for wind power generation, comprising a rounded corner prefabricated component and a flat plate prefabricated component that can be sequentially spliced ​​and connected, a plurality of prestressed steel bars penetrating and connecting the rounded corner prefabricated component and the flat plate prefabricated component, and anchors sleeved on both ends of the prestressed steel bars for fixing the prestressed steel bars; wherein the rounded corner prefabricated component comprises an arc-shaped main component and a connecting plate extending from the inner side of the two end surfaces of the arc-shaped main component, the outer side of the two end surfaces of the arc-shaped main component and the outer end surface of the connecting plate are respectively provided with a plurality of positioning and sealing grooves, and a plurality of first butting steel bars are also inserted on the outer side of the two end surfaces of the arc-shaped main component, The connecting plate has a through prestressed short channel; the flat prefabricated component includes a flat main component, both end surfaces of the flat main component have elastic clips adapted to the positioning sealing slot, and a plurality of inserted second butt steel bars, and the flat main component has a plurality of through prestressed long channels; when the rounded corner prefabricated component and the flat prefabricated component are spliced ​​with each other, the prestressed short channel and the prestressed long channel are connected so that the prestressed steel bars are passed through them, the elastic clips are correspondingly clamped in the positioning sealing slot, and the first butt steel bars and the second butt steel bars are cross-lapped.

[0009] Furthermore, a plurality of the prestressed short channels are arranged at equal intervals in the connecting plate, and a plurality of the prestressed long channels are arranged at equal intervals in the flat plate main component corresponding to a plurality of the prestressed short channels.

[0010] Furthermore, in the height direction of the rounded prefabricated component, the distance between the lowest prestressed short channel and the bottom end of the rounded prefabricated component is not less than 1m, the distance between the highest prestressed short channel and the top end of the rounded prefabricated component is not less than 1m, and the spacing between several prestressed short channels is not greater than 5m.

[0011] Furthermore, the width of the positioning and sealing groove is 4 mm to 6 mm greater than the width of the cross-sectional rectangle of the elastic clip strip.

[0012] Furthermore, the length-to-width ratio of the cross-sectional rectangle of the elastic clip is 1:1 to 1.5:1.

[0013] Furthermore, the prestressed long channel includes a straight channel in the middle and curved channels located on both sides of the straight channel; wherein the bending direction of the curved channel is consistent with the bending direction of the prestressed short channel when the rounded prefabricated component and the flat plate prefabricated component are spliced ​​with each other.

[0014] Furthermore, the outer surface of the rounded prefabricated component is tangent to the outer surface of the flat prefabricated component.

[0015] Furthermore, the number of the rounded prefabricated components and the number of the flat plate prefabricated components are both 4.

[0016] Another object of the present invention is to provide a method for assembling a wind power concrete tower, which is performed using any of the above-described prefabricated assembling structures for wind power concrete towers. The assembling method comprises the following steps:

[0017] S1. Apply structural adhesive in the positioning and sealing groove;

[0018] S2, splicing the rounded prefabricated component and the flat prefabricated component in sequence to form a cylindrical shape; wherein the first butt-jointed steel bars and the second butt-jointed steel bars are cross-lapped, and the elastic clip is clamped in the positioning and sealing slot coated with the structural adhesive;

[0019] S3, passing the prestressed steel bar through one of the prestressed short holes, one of the prestressed long holes and one of the prestressed short holes in sequence, and anchoring both ends of the prestressed steel bar with the anchors to obtain a prefabricated assembled tower for wind power;

[0020] S4. In the height direction of the prefabricated assembled tower for wind power generation, grouting material is poured from the lowest prestressed short channel. The grouting material passes through the through-length channel formed by the cross-lapping of the first butt-jointed steel bars and the second butt-jointed steel bars and completely fills the gap between the rounded prefabricated component and the flat prefabricated component from bottom to top to obtain the concrete tower for wind power generation.

[0021] Furthermore, the setting time of the structural adhesive is not less than 6 hours.

[0022] The present invention has the following beneficial effects:

[0023] (1) The present invention realizes assembly positioning through the interaction between the positioning sealing groove and the elastic clip strip. The installation position of the rounded corner prefabricated component and the flat prefabricated component can be determined by simply inserting the elastic clip strip into the positioning sealing groove. The installation and debugging are convenient and the assembly time is greatly saved.

[0024] (2) The purpose of sealing the joints can be achieved by using prestressed tension to extrude the elastic clips and cooperate with the structural adhesive during installation; this technology avoids the use of cement-based sealing materials in the prior art, thereby avoiding the problem of peeling of the sealing materials, which would lead to the risk of falling objects from high altitudes;

[0025] (3) The sealing method proposed in the present invention can withstand higher grouting pressure. After the assembly and splicing are completed, the construction of the wind power concrete tower can be completed by grouting from bottom to top only once, which greatly improves the assembly efficiency of the wind power concrete tower.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The present invention provides a prefabricated concrete tower assembly structure for wind power generation, which can be assembled by Figure 1 The rounded prefabricated components shown and Figure 2 The flat plate prefabricated components are assembled and connected in sequence, and grouting material is poured into the gap between the two to form a Figure 3 and Figure 4 The concrete tower for wind power shown.

[0039] See also Figure 1 to Figure 6 The prefabricated assembled structure of the wind power concrete tower includes a rounded prefabricated component 1 and a flat prefabricated component 2 which can be sequentially spliced ​​and connected, a plurality of prestressed steel bars 3 which penetrate and connect the two, and anchors 4 which are sleeved on both ends of the prestressed steel bars 3 and are used to fix the prestressed steel bars 3.

[0040] Specific as Figure 1As shown, the rounded corner prefabricated component 1 includes an arc-shaped main component 11 and a connecting plate 12 formed by extending the inner part of the two end surfaces of the arc-shaped main component 11, and the outer parts of the two end surfaces of the arc-shaped main component 11 and the outer end surfaces of the connecting plate 12 are respectively provided with a plurality of positioning and sealing grooves 13; these positioning and sealing grooves 13 are used for applying structural adhesive 5 when splicing the rounded corner prefabricated component 1 with the flat plate prefabricated component 2, so as to seal the gap formed when the rounded corner prefabricated component 1 and the flat plate prefabricated component 2 are spliced.

[0041] Specific as Figure 2 As shown, the flat prefabricated component 2 includes a flat main component 21, and both end surfaces of the flat main component 21 have elastic clips 22 that are compatible with the aforementioned positioning and sealing grooves 13; in this way, when the rounded corner prefabricated component 1 and the flat prefabricated component 2 are spliced ​​together, the elastic clips 22 can be placed in the positioning and sealing grooves 13 coated with structural adhesive 5, and they are bonded together by the structural adhesive 5.

[0042] The elastic clip strip 22 is arranged along the height direction of the flat plate prefabricated component 2, that is, the elastic clip strip 22 is an integral strip arranged along the height direction of the flat plate prefabricated component 2. In order to obtain a good matching relationship between the two, the width of the positioning sealing slot 13 is controlled to be 4mm to 6mm larger than the width of the cross-sectional rectangle of the elastic clip strip 22.

[0043] Generally, the length-to-width ratio of the cross-sectional rectangle of the elastic clip strip 22 can be controlled to be 1:1-1.5:1.

[0044] A plurality of first butt-jointing steel bars 14 are inserted on the outer sides of both end surfaces of the arc-shaped main component 11, and a plurality of second butt-jointing steel bars 23 are also inserted on both end surfaces of the flat plate main component 21; when the rounded corner prefabricated component 1 and the flat plate prefabricated component 2 are spliced ​​together, the first butt-jointing steel bars 14 can be cross-lapped with the second butt-jointing steel bars 23, thereby reinforcing the splicing of the two; and thereby forming a through-length channel for subsequent injection of grouting material 6, and allowing the grouting material 6 to completely fill all gaps formed by the splicing of the rounded corner prefabricated component 1 and the flat plate prefabricated component 2.

[0045] The connecting plate 12 has a through prestressed short channel 121, and the flat plate main part 21 has a through prestressed long channel 211; based on the height direction of the rounded corner prefabricated component 1 and the flat plate prefabricated component 2, the prestressed short channel 121 and the prestressed long channel 211 are arranged in the horizontal direction. In this way, when the rounded corner prefabricated component 1 and the flat plate prefabricated component 2 are spliced ​​with each other, the prestressed short channel 121 is connected with the prestressed long channel 211 and can accommodate the prestressed steel bars 3 to be inserted therein.

[0046] More specifically, the prestressed long channel 211 includes a straight channel in the middle and curved channels located on both sides of the straight channel; wherein the bending direction of the curved channel is consistent with the bending direction of the prestressed short channel 121 when the rounded corner prefabricated component 1 is spliced ​​on the flat plate prefabricated component 2. In other words, when the rounded corner prefabricated component 1 and the flat plate prefabricated component 2 are spliced ​​and connected to form a whole, each prestressed long channel 211 is connected to the prestressed short channels 121 located on both sides thereof by natural transition between the curved channel and the prestressed short channel 121 having the same bending direction.

[0047] Preferably, in order to ensure the beauty of the cylindrical object after the rounded prefabricated component 1 and the flat prefabricated component 2 are spliced ​​together, the arc on the outer surface of the rounded prefabricated component 1 and the straight line on the outer surface of the flat prefabricated component 2 are controlled to be tangent, that is, to ensure a soft transition between the rounded prefabricated component 1 and the flat prefabricated component 2 when they are spliced ​​together.

[0048] In the wind power concrete tower of the prefabricated and assembled structure of the wind power concrete tower based on the present invention, four rounded prefabricated components 1 and four flat prefabricated components 2 can be assembled to form a complete cylindrical wind power concrete tower.

[0049] The prefabricated assembled structure of the wind power concrete tower of the present invention, on the one hand, through the mutual overlap of the first butt-jointed steel bars 14 and the second butt-jointed steel bars 23, and the clamping effect of the positioning sealing groove 13 and the elastic clamping strip 22, on the other hand, also utilizes the prestressed tensioning effect of the prestressed steel bars 3 passed through two prestressed short channels 121 and one prestressed long channel 211, which not only ensures the tight splicing between the rounded corner prefabricated component 1 and the flat prefabricated component 2, and allows the grouting material 6 to be poured into the gap between the two at one time, but also this prestressed tensioning method can also make the elastic clamping strip 22 be compressed and deformed after the prestress is tensioned, and squeeze part of the structural adhesive 5 out of the positioning sealing groove 13, ensuring that the joint is tightly sealed, and further ensuring the grouting effect of the subsequent grouting material 6.

[0050] In each rounded corner prefabricated component 1, a plurality of prestressed short channels 121 are arranged in the connecting plate 12 at equal intervals in the height direction of the rounded corner prefabricated component 1; correspondingly, in each flat plate prefabricated component 2, a plurality of prestressed long channels 211 are also arranged in the flat plate main component 21 at equal intervals in the height direction of the flat plate prefabricated component 2. Preferably, the spacing is not greater than 5m.

[0051] Generally speaking, in the height direction of the rounded corner prefabricated component 1, the lowest prestressed short channel 121 is at least 1m away from the bottom end of the rounded corner prefabricated component 1, and the highest prestressed short channel 121 is at least 1m away from the top end of the rounded corner prefabricated component 1; that is, the distances from the two outermost prestressed short channels 121 of a group of equally spaced prestressed channels 121 to the top and bottom ends of the rounded corner prefabricated component 1 are both at least 1m. The same is true for the prestressed long channels 211 in the flat prefabricated component 2.

[0052] When assembling a wind power concrete tower based on the above-mentioned wind power concrete tower prefabricated assembly structure of the present invention, the following steps are generally used:

[0053] First, the structural adhesive 5 is applied into the positioning and sealing groove 13 .

[0054] Structural adhesive 5 is generally selected from the type whose setting time is not less than 6 hours.

[0055] Then, the rounded prefabricated component 1 and the flat prefabricated component 2 are spliced ​​in sequence to form a cylinder. At this time, the first butt-jointed steel bars 14 and the second butt-jointed steel bars 23 are cross-lapped, and the elastic clip 22 is clamped in the positioning and sealing groove 13 coated with the structural adhesive 5.

[0056] Again, the prestressed steel bar 3 is passed through a prestressed short channel 121, a prestressed long channel 211 and a prestressed short channel 121 in sequence, and both ends of the prestressed steel bar 3 are anchored with anchors 4 to obtain a prefabricated assembled tower for wind power.

[0057] In this way, the structural adhesive 5 in the positioning and sealing groove 13 is partially squeezed out under the action of the prestressed steel bar 3, thereby further sealing the gap between the rounded prefabricated component 1 and the flat prefabricated component 2.

[0058] Finally, in the height direction of the prefabricated assembled tower for wind power, grouting material 6 is poured from the lowest prestressed short channel 121, and the grouting material 6 is first filled into the lowest gap between the rounded prefabricated component 1 and the flat prefabricated component 2, and the channel formed by the lowest prestressed short channel 121 and the lowest prestressed long channel 211; when the grouting hole in the lowest anchor 4 begins to ooze, it is blocked to allow the grouting material 6 to "move" upward along the through-length channel formed by the overlap of the first butt-jointed steel bars 14 and the second butt-jointed steel bars 23, and so on until the gap between the rounded prefabricated component 1 and the flat prefabricated component 2 is completely filled from bottom to top, and the concrete tower for wind power is obtained after the grouting material 6 hardens.

[0059] The above-mentioned grouting process from bottom to top can also discharge the air in the gap between the rounded corner prefabricated component 1 and the flat plate prefabricated component 2 upwards at the same time, so as to avoid the air from having an adverse effect on the hardening strength of the grouting material 6 .

[0060] In this way, based on the prefabricated assembly structure of the wind power concrete tower and combined with a one-time grouting operation, the assembly of the wind power concrete tower is realized, which is easy to position and convenient to assemble. Compared with the existing technology, the problem of falling objects from high altitude caused by the use of cement-based sealing materials is avoided, and grouting can be performed once without accommodating cement-based sealing materials, which also greatly improves the assembly efficiency of the wind power concrete tower.

[0061] While the invention has been shown and described with reference to the particular embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the claims and their equivalents.
