Description

Technical Field

[0001] The invention relates to the technical field of pier column formwork, and in particular to a pier column formwork assembly and a pier column construction method. Background Art

[0002] In the construction industry, pier formwork components are important components used to support and fix the shape of piers during concrete pouring. In traditional methods, pier formwork components are usually composed of wooden formwork or steel formwork, which are fixed by bolts and other connection methods. Wooden formwork is easily deformed by moisture, while steel formwork is the most commonly used.

[0003] However, when pouring pier concrete, the concrete will form stress that spreads outward in multiple directions, and most of the existing adjacent steel formworks are only connected and fixed by bolts in a single direction, which causes the bolts to be subjected to large stress, easily causing structural instability and affecting the quality of concrete pouring. Summary of the invention

[0004] The invention provides a pier column formwork assembly and a pier column construction method, which can overcome certain or some defects of the prior art.

[0005] A pier formwork assembly and a pier construction method according to the present invention include an assembly body, the assembly body includes a first formwork and a second formwork vertically connected to each other, the first formwork and the second formwork both have a flat plate portion in contact with concrete and a reinforcement portion, the reinforcement portion at the first formwork is provided with a second support structure, and the reinforcement portion at the second formwork is provided with a first support structure; A plurality of locking components are formed at the corresponding positions of the side walls on both sides of the second supporting structure and the first template along the length direction, plug-in grooves are formed between the plurality of locking components and the side walls on both sides of the first template, and plug-in parts matching the plug-in grooves are formed at the side walls on both sides of the second template along the length direction, and the plug-in grooves are used to lock the plug-in parts; A high-strength tie rod is detachably provided between the first supporting structure and the second supporting structure. The high-strength tie rod is used to connect the first supporting structure and the second supporting structure and to limit the locking assembly.

[0006] By first fixing the first formwork and the second formwork along the length direction of the first formwork and then fixing the first formwork and the second formwork in a direction perpendicular to the diagonal line, it is achieved that the first formwork and the second formwork are simultaneously limited and fixed in two directions, thereby improving the connection stability between the first formwork and the second formwork and avoiding the problem of connection and fixation by bolts in only a single direction, which results in greater force on the bolts and easily causes structural instability and affects the quality of concrete pouring.

[0007] In addition, by providing a high-strength tie rod, the first supporting structure and the second supporting structure are fixed, and the locking assembly is also locked, further improving the connection stability between the first template and the second template.

[0008] It can be understood that by connecting the first template and the second template through plug-in connection, they can be quickly positioned in the horizontal direction, and then quickly locked with the locking assembly, which simplifies the installation and disassembly process, reduces the construction difficulty and labor intensity, and construction personnel can quickly and accurately complete the assembly and disassembly of the template, thereby improving construction efficiency.

[0009] The second truss or the second connecting part can also be used as a working platform for construction workers when pouring concrete or performing maintenance.

[0010] Preferably, the first supporting structure has a plurality of first trusses arranged at equal intervals along the length direction of the second template, the first trusses are used to provide support for the second template in the length direction, and a plurality of first connecting square tubes are provided between the plurality of first trusses, the first connecting square tubes are used to provide support for the second template in the vertical direction.

[0011] Through the coordinated arrangement of the first truss and the first connecting square tube, comprehensive support for the second formwork in the length and vertical directions is achieved, which not only improves the overall stability and bearing capacity of the formwork, but also improves the integrity and stability of the formwork assembly during construction.

[0012] Preferably, the second supporting structure has a plurality of second trusses arranged at equal intervals along the length direction of the first template, the second trusses are used to provide support for the length direction of the first template, and a plurality of second connecting square tubes are provided between the plurality of second trusses, the second connecting square tubes are used to provide support for the second trusses in the vertical direction.

[0013] Through the coordinated arrangement of the second truss and the second connecting square tube, comprehensive support for the first formwork in the length and vertical directions is achieved, which not only improves the overall stability and bearing capacity of the formwork, but also makes the integrity and stability of the formwork assembly better during construction. Therefore, it is better to avoid the situation where the formwork is easily exploded after the pier is cast to a certain height, resulting in rework, and improving the casting efficiency and safety.

[0014] Preferably, the multiple locking assemblies correspond to the second truss, and the locking assemblies include a fixed block arranged at the second truss and parallel to the side wall of the first template, an installation cavity arranged along the length direction of the first template is formed inside the fixed block, a plug-in component is slidably provided inside the installation cavity, the plug-in component is provided with an insertion rod passing through the installation cavity and extending into the insertion groove, the other end of the plug-in component passes through the installation cavity and extends to the outside of the installation cavity, a first spring is provided between the plug-in component and the installation cavity, the first spring is used to provide an elastic force to keep the plug-in component pressed toward the direction of the insertion groove, and the multiple locking assemblies are commonly provided with a pressure plate, and the pressure plate is used to drive the insertion rod to slide along the direction of the installation cavity.

[0015] Among them, the fixing block is arranged at the second truss and is arranged parallel to the side wall of the first template, providing a plug-in guide for the plug-in part at the second template, and can quickly position the second template in the vertical and horizontal directions, thereby improving the installation efficiency.

[0016] Among them, a first spring is provided between the connector and the installation cavity, and the first spring provides elastic force to keep the connector pressed toward the insertion slot, ensuring that the insertion rod can always remain in the insertion slot when the connector is not subject to external force, thereby enhancing the connection stability between the template components.

[0017] Among them, multiple locking components are jointly provided with a pressure plate, which can drive the insertion rod to slide along the direction of the installation cavity, so that when unlocking is required, the insertion rods of multiple locking components can be driven to slide simultaneously by operating the pressure plate, thereby simplifying the unlocking process.

[0018] Preferably, an inwardly recessed groove cooperating with the pressing plate is formed at the end of the second truss, the groove is used to form a locking position for the pressing plate, and the pressing plate is formed with a fixing portion connected to the insertion rod.

[0019] By cooperating with the groove and the pressure plate, the pressure plate can be stably clamped in the groove, further improving the locking stability of the locking assembly.

[0020] Preferably, a first connecting portion parallel to the diagonal line of the first template and the second template is formed at both end portions of the first truss, and a second connecting portion parallel to the diagonal line of the first template and the second template is formed at both end portions of the second truss. Through holes perpendicular to the first connecting portion and the second truss are formed at the first connecting portion and the second truss, and the through holes are for high-strength tension rods to pass through for connecting the first truss and the second truss.

[0025] Preferably, a plurality of corresponding holes are formed on the side walls on both sides along the length direction of the first template, and the corresponding holes are used for the insertion of the plug rods.

[0026] By inserting the insertion rod into the corresponding hole, the stability of the first template can be effectively enhanced, so that the first template can better resist deformation and displacement when subjected to external force. At the same time, the insertion part at the second template can be better limited, thereby ensuring the construction quality and safety of the template assembly.

[0027] Preferably, a through hole corresponding to the corresponding hole is formed at the plug-in portion, and the through hole is used for plugging the plug-in rod. Therefore, the plug-in portion can be preferably limited, simplifying the connection method of the first template and the second template.

[0040] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0041] Example 1 See also Figure 1-4 The present embodiment provides a pier column formwork assembly, which includes an assembly body 100, the assembly body 100 includes a first formwork 110 and a second formwork 120 vertically connected to each other, the first formwork 110 and the second formwork 120 both have a flat plate portion in contact with concrete and a reinforcement portion, the reinforcement portion at the first formwork 110 is provided with a second support structure 140, and the reinforcement portion at the second formwork 120 is provided with a first support structure 130; A plurality of locking components 250 are formed at the corresponding positions of the side walls on both sides of the second supporting structure 140 and the first template 110 along the length direction, and plug-in grooves 420 are formed between the plurality of locking components 250 and the side walls on both sides of the first template 110. A plug-in portion 310 matching the plug-in groove 420 is formed at the side walls on both sides of the second template 120 along the length direction, and the plug-in groove 420 is used to lock the plug-in portion 310. A high-strength tie rod 240 is detachably provided between the first supporting structure 130 and the second supporting structure 140 . The high-strength tie rod 240 is used to connect the first supporting structure 130 and the second supporting structure 140 and to limit the locking assembly 250 .

[0042] A pier column formwork assembly disclosed in the present invention first fixes the first formwork 110 and the second formwork 120 along the length direction of the first formwork 110, and then fixes the first formwork 110 and the second formwork 120 in a direction perpendicular to the diagonal line, thereby achieving simultaneous limited fixation of the first formwork 110 and the second formwork 120 in two directions, improving the connection stability of the first formwork 110 and the second formwork 120, and avoiding the problem that the bolts are subjected to greater force due to connection and fixation in only a single direction, which easily causes structural instability and affects the quality of concrete pouring.

[0043] In addition, by providing the high-strength tie rod 240 , the first support structure 130 and the second support structure 140 are fixed while the locking assembly 250 is locked, further improving the connection stability between the first template 110 and the second template 120 .

[0044] It can be understood that by first connecting the first template 110 and the second template 120 through plug-in connection, they can be quickly positioned in the horizontal direction, and then quickly locked with the locking assembly 250, which simplifies the installation and disassembly process, reduces the construction difficulty and labor intensity, and construction personnel can quickly and accurately complete the assembly and disassembly of the template, thereby improving construction efficiency.

[0045] The second truss 260 or the second connecting portion 280 may also be used as a working platform for construction workers when pouring concrete or performing maintenance.

[0046] See Figure 2 In this embodiment, the first supporting structure 130 has a plurality of first trusses 210 arranged at equal intervals along the length direction of the second template 120, and the first trusses 210 are used to support the second template 120 in the length direction. A plurality of first connecting square tubes 220 are arranged between the plurality of first trusses 210, and the first connecting square tubes 220 are used to support the second template 120 in the vertical direction.

[0047] By cooperating with the first truss 210 and the first connecting square tube 220, comprehensive support is achieved for the second template 120 in the length direction and the vertical direction, which not only improves the overall stability and bearing capacity of the template, but also makes the template assembly 100 more integrated and stable during construction.

[0048] See Figure 2 In this embodiment, the second supporting structure 140 has a plurality of second trusses 260 arranged at equal intervals along the length direction of the first template 110, and the second trusses 260 are used to support the first template 110 in the length direction. A plurality of second connecting square tubes 270 are arranged between the plurality of second trusses 260, and the second connecting square tubes 270 are used to support the second trusses 260 in the vertical direction.

[0049] By cooperating with the second truss 260 and the second connecting square tube 270, comprehensive support is achieved for the first formwork 110 in the length direction and the vertical direction, which not only improves the overall stability and bearing capacity of the formwork, but also makes the integrity and stability of the formwork assembly 100 better during construction. Therefore, it is better to avoid the mold explosion after the pier is poured to a certain height, resulting in rework, thereby improving the pouring efficiency and safety.

[0050] See Figure 4 and Figure 6 In this embodiment, the multiple locking components 250 correspond to the second truss 260. The locking components 250 include a fixed block 410 arranged at the second truss 260 and parallel to the side wall of the first template 110. An installation cavity 610 arranged along the length direction of the first template 110 is formed inside the fixed block 410. A plug-in component 620 is slidably provided inside the installation cavity 610. The plug-in component 620 is provided with an insertion rod 630 that penetrates the installation cavity 610 and extends into the insertion groove 420. The other end of the plug-in component 620 penetrates the installation cavity 610 and extends to the outside of the installation cavity 610. A first spring 660 is provided between the plug-in component 620 and the installation cavity 610. The first spring 660 is used to provide an elastic force to keep the plug-in component 620 pressed toward the direction of the insertion groove 420. The multiple locking components 250 are jointly provided with a pressing plate 430, and the pressing plate 430 is used to drive the insertion rod 630 to slide along the installation cavity 610.

[0051] Among them, the fixing block 410 is arranged at the second truss 260 and is arranged parallel to the side wall of the first template 110, providing a plug-in guide for the plug-in part 310 at the second template 120, and can quickly position the second template 120 in the vertical and horizontal directions, thereby improving the installation efficiency.

[0052] Among them, a first spring 660 is provided between the connector 620 and the installation cavity 610. The first spring 660 provides an elastic force to keep the connector 620 pressed toward the plug-in slot 420, ensuring that the connector 620 can always remain in the plug-in slot 420 when no external force is applied, thereby enhancing the connection stability between the template assemblies 100.

[0053] Among them, multiple locking assemblies 250 are commonly provided with a pressure plate 430, which can drive the insertion rod 630 to slide along the direction of the installation cavity 610, so that when unlocking is required, the insertion rods 630 of multiple locking assemblies 250 can be driven to slide simultaneously by operating the pressure plate 430, thereby simplifying the unlocking process.

[0054] See Figure 5 and Figure 6In this embodiment, an inwardly recessed groove 510 cooperating with the pressing plate 430 is formed at the end of the second truss 260 , and the groove 510 is used to form a locking position for the pressing plate 430 , and the pressing plate 430 is formed with a fixing portion 640 connected to the insertion rod 630 .

[0055] By cooperating with the groove 510 and the pressing plate 430 , the pressing plate 430 can be stably stuck in the groove 510 , further improving the locking stability of the locking assembly 250 .

[0056] In this embodiment, first connecting portions 230 parallel to the diagonal line of the first template 110 and the second template 120 are formed at both ends of the first truss 210, and second connecting portions 280 parallel to the diagonal line of the first template 110 and the second template 120 are formed at both ends of the second truss 260. Through holes 710 perpendicular to the first connecting portions 230 and the second trusses 260 are formed at the first connecting portions 230 and the second trusses 260, and the through holes 710 are for the high-strength tension rods 240 to pass through for connecting the first truss 210 and the second trusses 260.

[0057] By providing the first connection part 230 and the second connection part 280 and the high-strength tie rod 240, the right-angle diagonal line at the intersection of the adjacent first formwork 110 and the second formwork 120 is fixed in the vertical direction, thereby enhancing the structural stability of the pier formwork assembly 1000 and improving the connection stability between the first formwork 110 and the second formwork 120.

[0058] See Figure 6 and Figure 7 In this embodiment, an oblique hole 650 for the high-strength tie rod 240 to pass through is formed at the pressing plate 430 . The oblique hole 650 corresponds to the through hole 710 and is perpendicular to the second connecting portion 280 .

[0059] Through the above structure, the high-strength tie rod 240 can not only be connected to the first truss 210 and the second truss 260 through the through hole 710, but also be connected to the pressing plate 430 through the inclined hole 650, thereby forming a more stable overall structure.

[0060] It can be understood that the high-strength tie rod 240 passes through the inclined hole 650 , so that the pressing plate 430 and the high-strength tie rod 240 form a triangle, so that the pressing plate 430 can be locked in the groove 510 .

[0061] In this embodiment, a plurality of corresponding holes 670 are formed on the side walls of the first template 110 along the length direction, and the corresponding holes 670 are used for the insertion of the insertion rods 630.

[0062] By inserting the insertion rod 630 into the corresponding hole 670, the stability of the first template 110 can be effectively enhanced, so that the first template 110 can better resist deformation and displacement when subjected to external force. At the same time, the plug-in portion 310 at the second template 120 can be better limited, thereby ensuring the construction quality and safety of the template assembly.

[0063] See Figure 6 In this embodiment, a through hole 320 corresponding to the corresponding hole 670 is formed at the plug-in portion 310, and the through hole 320 is used for plugging the plug rod 630. Therefore, the plug-in portion 310 can be preferably limited, simplifying the connection method of the first template 110 and the second template 120.

[0064] Example 2 This embodiment provides a pier column construction method, comprising the following steps: S1. Position and lay out the piers to ensure that the size, position and elevation of the piers are accurate; S2, constructing a mold, lifting a preset number of template components one by one to the reference position, stacking the preset number of template components in sequence from bottom to top, and fixing the adjacent first templates 110 and second templates 120 to be connected; S3, pouring concrete, pouring concrete of a preset height into the completed mold, and vibrating the concrete; S4. Maintain the formed concrete columns; S5. Remove the mold.

[0065] Through the above, the assembly can be performed quickly, thereby improving the efficiency of installing and disassembling the adjacent first templates 110 and second templates 120.

[0066] Example 3 See also Figure 1-4 The present embodiment provides a pier column formwork assembly that can be quickly spliced, which includes an assembly body 100, the assembly body 100 includes a first formwork 110 and a second formwork 120 vertically connected to each other, the first formwork 110 and the second formwork 120 both have a flat plate portion in contact with concrete and a reinforcement portion, the reinforcement portion is provided with a frame 340, and an installation groove is formed between the frame 340 and the reinforcement portion; A plurality of mounting holes arranged at equal intervals are provided on the top wall of the frame 340, and a positioning piece 360 ​​penetrating the mounting holes is detachably provided on the top wall of the mounting groove, and a plug-in hole 350 corresponding to the positioning piece 360 ​​is formed on the bottom wall of the mounting groove. The positioning piece 360 ​​is used to penetrate the frame 340 at the first template 110 or the second template 120 of the adjacent upper layer to lock the first template 110 or the second template 120 of the adjacent upper layer.

[0067] The present invention discloses a pier column formwork assembly that can be quickly spliced. Through the above-mentioned structure, when the upper first formwork 110 or the second formwork 120 is hoisted, when the upper first formwork 110 or the second formwork 120 is docked with the lower first formwork 110 or the second formwork 120, the positioning member 360 can quickly insert and position the insertion hole 350 at the upper first formwork 110 or the second formwork 120, and form a lock.

[0068] It can be understood that, compared with the prior art in which the second trusses 260 are connected by bolts, the present invention does not need to collect the second trusses 260 separately, thus reducing the workload of subsequent disassembly.

[0069] See Figure 1 In this embodiment, a plurality of reinforcing ribs are provided at equal intervals in the installation groove, and the plurality of reinforcing ribs are arranged in a vertical direction along the first template 110 or the second template 120 .

[0070] Through the above structure, the vertical strength of the first template 110 or the second template 120 is improved, so that the first template 110 or the second template 120 can better resist the stress and deformation generated when pouring concrete.

[0071] See Figure 3 In this embodiment, a positioning rod 330 protruding upward is formed at the top of the frame 340, and a positioning hole 370 corresponding to the positioning rod 330 is formed at the bottom wall of the mounting groove. The positioning hole 370 is used to cooperate with the positioning rod 330 at the upper adjacent first template 110 or second template 120.

[0072] By coordinating the positioning rod 330 and the positioning hole 370, the upper first template 110 or the second template 120 can be spliced ​​more quickly and accurately during the hoisting process without complicated adjustments and corrections, thereby effectively shortening the construction period and improving construction efficiency.

[0073] It can be understood that, through the cooperation between the positioning rod 330 and the positioning hole 370, the connection between the upper first template 110 or the second template 120 and the lower first template 110 or the second template 120 is made tighter and more stable.

[0074] See Figure 8In this embodiment, the positioning member 360 includes a shell 810, a sliding cavity 960 with an opening downward is formed inside the shell 810 along the height direction, a cover plate 980 is detachably provided at the opening, a locking member 820 is slidably provided in the sliding cavity 960 along the height direction of the shell 810, the locking member 820 has a plug-in portion 1010 passing through the top wall of the sliding cavity 960, and a threaded portion 1020 passing through the cover plate 980, a fastener 830 is threadedly matched at the threaded portion 1020, the fastener 830 is used to adjust the length of the locking member 820 extending along the height direction of the shell 810, and a retaining ring 1030 for blocking the bottom of the fastener 830 is formed at the threaded portion 1020.

[0075] The locking member 820 is slidably disposed in the sliding cavity 960 along the height direction of the shell 810, and cooperates with the threaded portion 1020 and the fastener 830, so that the locking member 820 can adjust the height according to actual needs, thereby adapting to the requirements of locking and connecting the first template 110 or the second template 120 with different thicknesses.

[0076] It can be understood that the retaining ring 1030 can block the bottom wall of the fastener 830 to prevent the fastener 830 from falling off.

[0077] See Fig. 9 In this embodiment, a slide groove 961 is formed on the inner wall of the sliding cavity 960 along the height direction of the shell 810, and an extension plate 942 that cooperates with the sliding cavity 960 and the slide groove 961 is formed on the outer wall of the locking member 820. The slide groove 961 is used to limit the extension plate 942 in the circumferential direction. A third spring 970 is provided between the bottom wall of the extension plate 942 and the cover plate 980. The third spring 970 is used to provide an elastic force to keep the extension plate 942 pressed upward.

[0078] Through the above structure, when the upper first template 110 or the second template 120 is hoisted, the locking member 820 can be quickly positioned when the upper first template 110 or the second template 120 is docked with the lower first template 110 or the second template 120.

[0079] In addition, the provision of the third spring 970 enables the locking piece 820 to be pressed down when the upper first template 110 or the second template 120 contacts the locking piece 720 at the lower first template 110 or the second template 120, thereby avoiding damage to the locking piece 820. At the same time, the pressed locking piece 820 can automatically rebound through the third spring 970 after the position of the upper first template 110 or the second template 120 is adjusted, thereby being inserted into the plug-in hole 350 at the upper first template 110 or the second template 120 to form a connection, thereby improving splicing accuracy and construction efficiency.

[0080] See Fig. 9 and Fig.10In this embodiment, a downwardly opening installation cavity 910 is formed inside the locking member 820 along the length direction, and a plurality of through openings 920 penetrating the installation cavity 910 are formed at the outer wall of the plug-in portion 1010. The plurality of through openings 920 are arranged at equal intervals along the circumference of the plug-in portion 1010, and a clamping jaw 930 is rotatably provided in the through opening 920. A releasing member 940 is provided on the inner thread of the installation cavity 910, and the releasing member 940 is used to drive the clamping jaw 930 to rotate.

[0081] Through the above structure, when disassembling, the clamping jaw 930 can be rotated to the inside of 920 by reversing the release member 940, so that the first template 110 and the second template 120 can be disassembled. The rotation of the clamping jaw 930 can be achieved by simply rotating the release member 940, thereby controlling the clamping or release between the clamping jaw 930 and the upper first template 110 or the second template 120. The operation is simple and fast.

[0082] It can be understood that by rotating the fastener 830, the clamp 930 can form a support with the bottom wall of the installation groove of the upper first template 110, thereby further fastening the upper first template 110 or the second template 120, thereby improving the connection reliability between the upper first template 110 or the second template 120 and the lower first template 110 or the second template 120.

[0083] See Fig. 9 In this embodiment, a second spring 950 is provided between the top wall of the release member 940 and the top wall of the installation cavity 910, and the second spring 950 is used to maintain the elastic force that presses the release member 940 downward.

[0084] The provision of the second spring 950 helps to maintain the stability of the locking member 820 in the installation cavity 910, prevents loosening or falling off due to external force or vibration, and improves the connection stability between the release member 940 and the locking member 820.

[0085] See Fig. 9 In this embodiment, a protrusion 931 extending into the locking member 820 is formed at the clamping claw 930 , and a recess 941 cooperating with the protrusion 931 is formed at the outer wall of the releasing member 940 .

[0086] Through the above structure, when the release member 940 rotates or moves, the recess 941 drives the protrusion 931 to perform corresponding actions, thereby realizing the opening or closing of the clamping jaws 930.

[0087] See Figure 8 In this embodiment, an external thread is formed at the top of the outer wall of the shell 810, and an internal thread that matches the external thread of the shell 810 is formed on the inner wall of the mounting hole.

[0088] By rotating the housing 810, it can be easily screwed into or out of the mounting hole, which is not only simple and quick, but also does not require additional tools or equipment, thereby reducing the difficulty and cost of installation and removal.

[0089] It is understandable that the positioning members 360 are permanently disposed at the mounting holes, so that when one of the positioning members 360 is damaged, it is easy to replace.

[0090] Example 4 This embodiment provides a method for quickly splicing a pier column formwork assembly, which is used for a quickly splicing pier column formwork assembly described in Example 3, and comprises the following steps: S1. After the lower assembly body 100 is erected, the first template 110 or the second template 120 of the upper layer is hoisted to the top of the corresponding first template 110 or the second template 120 of the lower layer by a crane, and the positioning rod 330 at the top of the first template 110 or the second template 120 of the lower layer is plugged into the positioning hole 370 of the first template 110 or the second template 120 of the upper layer; S2, adjusting the position of the upper first template 110 or the second template 120, docking the positioning member 360 at the lower first template 110 or the second template 120 with the plug hole 350 at the upper first template 110 or the second template 120, to form a preliminary positioning; S3, tighten the positioning member 360 to finally fix the upper first template 110 or the second template 120, and repeat the above steps to install in a cycle.

[0091] Through the above, the connection efficiency of the upper first template 110 or the second template 120 is preferably improved.

[0092] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.
