Description

Technical Field

[0001] This invention relates to the field of roof tile technology, and more specifically, to a construction method for a steel frame pitched roof tile structure. Background Technology

[0002] With economic development and the improvement of people's living standards, people have higher requirements for the quality of material enjoyment. The appearance of buildings has become an important criterion for homeowners when choosing a house. European-style tiled roofs are also a popular trend. While these roofs require a beautiful appearance, they also emphasize the sturdiness of the tiles. The difficulty in construction lies in ensuring that the tiles are firmly attached and can withstand the test of spring and autumn winds. Summary of the Invention

[0003] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] To at least partially solve the above problems, the present invention provides a construction method for a steel frame pitched roof with tile hanging structure, comprising the following steps: S1: Construction preparation; S2: Construction of the water-flow strip; S3: Wooden sheathing installation; S4: Construction of batten installation; S5: Roofing tile installation; S6: Detail node processing.

[0005] Preferably, step S1 further includes: S101: Inspect the steel structure, roof gutter waterproofing and protective layer, roof equipment foundation and components protruding from the roof to ensure that the steel structure passes inspection, the roof base (such as gutter waterproofing) is completed, and protective facilities are built around the roof after inspection. S102: Determine the roof outline and mark the baseline.

[0006] Preferably, step S102 further includes: S1021: Pop up the center line of the roof ridge; S1022: Pop up the first horizontal line parallel to the eaves to determine the position of the first layer of tiles; S1023: Display the start and end lines for horizontal tile laying, both of which are perpendicular to the first horizontal line; S1024: Calculate and mark the position lines of all battens, ensuring that the spacing meets the tile overlap requirements (for example, when the slope is 15°~17.5°, the spacing should not exceed 345mm).

[0007] Preferably, step S2 further includes: Galvanized square tubing is selected as the drain trim. When installing drain trim on ridges, eaves, gable walls, and drainage ditches, ensure it is straight. When installing drain trim for drain hooks... S201: First determine the location of the drainage ditch, and then determine the width of the drainage ditch based on the size of the catchment area, the design slope, and the rainfall. S202: After determining the width of the drainage ditch, draw the center line of the drainage ditch. Using the center line as a reference, install two water-following strips according to the width requirements. S203: Mark the lines according to the net spacing requirements, arrange the water flow strips according to the marked lines, and weld them to the steel structure below at four points to ensure that the water flow strips are straight. After welding, apply anti-rust paint to the entire surface.

[0008] Preferably, step S3 further includes: S301: Mark the starting point of the wooden plank arrangement on each purlin along the span direction, and the line connecting the starting points is perpendicular to the longitudinal axis of the building; S302: Apply fire-retardant coating to all six sides of the wooden plywood before installation; S303: Start installing the wooden planks from the starting line, using side brackets and middle brackets for fixation, ensuring a tight fit between the planks. During installation, check the fit quality and installation deviations, and adjust them in a timely manner. S304: Finishing touches If the remaining purlin length is less than one-quarter of the width of the veneer, use the side bracket to hold the male edge of the veneer, then saw off the excess part of the side bracket, and then cover the remaining part with the edge trimming board; If the remaining purlin length is less than the width of the shingle but greater than one-quarter of the shingle width, cut off the portion of the shingle that extends beyond the purlin and fix it with a central bracket, then use side brackets to press down the male edge of the shingle.

[0009] Preferably, step S4 further includes: Galvanized thin-walled square tubing was selected as the roofing strip. The battens are vertically fixed to the runner strips and fully welded to each runner strip from top to bottom, and then rust-proofed. The batten joints are staggered, and the upper edge of the batten is kept in a straight line. When there is a drainage ditch in the roof, install the drainage ditch first and then install the battens; Two tile strips are installed at the eaves.

[0010] Preferably, step S5 further includes: S501: Before laying the tiles, mark a longitudinal straight line and mark a line 50mm away from the left and right eaves of the tile strip layer as a reference for laying the tiles to ensure that the tile joints are vertical. S502: Pre-laying. Large-area roofs require pre-laying. The effective width of the main tile is distributed according to the horizontal length of the roof. The position is adjusted by using the adjustment distance (about 4mm) of the tile overlap edge reinforcement to adjust the end tile to a whole tile or half tile. S503: Formal tile laying begins from the lower right corner of the eaves, proceeding from right to left and from bottom to top. Horizontal overlaps are arranged with the left tile pressing against the right tile, with a minimum overlap length of 40mm. Vertical overlaps are arranged with the front end of the upper tile pressing against the rear end of the lower tile, with a minimum overlap length of 75mm. The rear claws of the tiles must be tightly fastened to the battens and fit snugly with the adjacent tiles in the groove. During laying, a diagonal line can be drawn from the ridge to the eaves to control the straightness of the tile groove.

[0011] Preferably, step S5 further includes: For special areas, such as ridges and gutters, it is necessary to mark lines and cut tiles on-site to ensure tight overlap (e.g., the overlap width at the edge of the gutter should not be less than 150mm).

[0012] Preferably, step S6 further includes: For ridge treatment, after the batten installation is completed, fix the wooden support frame (500mm spacing) to the batten, then fix the galvanized thin-walled square tube to the wooden support frame, then paste the ventilated and waterproof membrane along the ridge direction, and then install the ridge tile on the galvanized thin-walled square tube. The overlap between the ridge tile and the flat tile on each side should not be less than 40mm. For the eaves treatment, install metal fascia boards, with the eaves tiles projecting outwards by 50mm to 70mm; For the roof retaining wall treatment, apply self-adhesive waterproof membrane and fix and seal it with aluminum pressure strips and weather-resistant sealant.

[0013] Preferably, step S6 further includes: For drainage ditch treatment, after marking the lines according to the design width, install the aluminum drainage ditch, ensuring that the overlap length of the upper and lower drainage ditches is not less than 150mm.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: The construction method of steel frame pitched roof with tile structure fully combines design concept and geographical environment, and has a higher ability to resist wind pressure. The tile roof is both beautiful and strong and can withstand the test of monsoon climate.

[0015] 1. In view of the geographical environment and the influence of monsoon and the vortex updraft pressure generated by the wind in the cluster of buildings in a large high-rise community, this application uses galvanized square steel as the water-guiding strip and the tile strip, and adopts welding connection to enhance the overall strength of the roof tile and improve the firmness of the tile.

[0016] 2. The use of wooden planks to fill the gaps between the water strips instead of precast concrete slabs reduces the roof load and the amount of steel used in the roof steel frame.

[0017] 3. The tiling technology for pitched roofs in this application clarifies the standardized steps and quality control requirements from layout and frame installation to tile laying, ensuring the safety, stability and reliability of the roof tiles.

[0018] The construction method for steel frame pitched roof tile structure of the present invention, other advantages, objectives and features of the present invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of the present invention.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0025] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0026] like Figures 1-4 As shown, the present invention provides a construction method for a steel frame pitched roof with tile hanging structure, including the following steps: S1: Construction preparation; Furthermore, step S1 also includes: S101: Acceptance inspection, inspect the steel structure project, roof gutter waterproofing and protective layer, roof equipment foundation and ventilation openings and other components protruding from the roof. After the acceptance is completed, construct protective facilities around the roof. S102: Lay out the lines, determine the roof outline, and mark the baseline.

[0027] Furthermore, step S102 also includes: S1021: Determine the roof outline, mark the center line on the ridge, and try to make the roof symmetrical or the two parts parallel. S1022: At the position above the eaves, mark the first parallel line parallel to the eaves to determine the position of the first layer of roof tiles; S1023: Display the starting and ending lines for horizontal tile laying. Both the starting and ending lines are perpendicular to the first horizontal line, and the position of the starting and ending lines from the eaves is determined by the shape of the tiles. S1024: Determine the number of roof tiles to be laid horizontally and vertically. Based on the product technical requirements and roof slope, determine the minimum overlap length of the roof tiles. Then calculate and determine the spacing of the batten strips, and mark the position lines of all batten strips to ensure that the spacing meets the tile overlap requirements.

[0028] As one of many implementation methods, the roofing detailing project of the sixth section (plot 610) of the Baoshan Village resettlement housing plot (phase one) project in Haidian District is taken as an example. In this project, firstly, a parallel line parallel to the ridge is marked 30mm down from the outline of the main ridge (a line must be marked on each side of the roof). This parallel line forms the midline, dividing the roof into two symmetrical parts. This parallel line can determine the position of the top row of battens, which is the termination line.

[0029] Then measure 350mm upwards from the eaves and mark a parallel line parallel to the edge of the eaves. This first parallel line determines the position of the first row of tile strips, i.e., the starting line.

[0030] Then, in the area between the starting line and the eaves edge, measure 50mm upwards from the eaves and draw a parallel line parallel to the eaves edge to determine the position of the first row of tiles on the eaves (it should be noted that no grouting is performed in this project, and this line is only used as a construction line).

[0031] Finally, measure a fixed length L from the first parallel line toward the center line at the left and right eaves. Since the lengths of the left and right eaves are rarely equal, the first parallel line and the center line will not be parallel, resulting in the distance between the first parallel line and the center line being unequal at each position. If the extreme value of the distance between the first parallel line and the center line (i.e., the difference between the maximum and minimum distance between the first parallel line and the center line) is too large, the first parallel line or the center line can be adjusted according to the actual situation to ensure that the height difference between the left and right ends of each row of tiles does not exceed 5mm.

[0032] It is important to note that the spacing of the batten strips should not exceed the specified effective length to ensure the minimum overlap length between roof tiles, allowing the eaves of the upper row of tiles to cover the nail holes of the lower row, preventing leaks. If the roof slope is between 15° and 17.5°, the spacing of the batten strips should not exceed the minimum effective size of 345mm. To ensure even spacing between rows after tile installation, starting from the beginning line of the first row, mark a line at equal intervals upwards until reaching the center line.

[0033] S2: Construction of the water-flow strip; Furthermore, step S2 also includes: S201: Before installing the drainage strip, determine the location of the drainage ditch and determine the width of the drainage ditch based on the size of the catchment area, the design slope, and the amount of rainfall; S202: After determining the width of the drainage ditch, draw the center line of the drainage ditch. Using the center line as a reference, install two water-following strips according to the width requirements. S203: Galvanized square tubes are selected as the drainage strips. The drainage strips are arranged according to the required net spacing. The additional drainage strips are first installed at the ridge, eaves, gable walls, drainage ditches, skylights, chimneys, etc. On the premise of ensuring the roof size, a straight line is drawn at the intersection of the end point of the ridge and the eaves line as the calibration line to ensure that the additional drainage strips can be installed straight. The drainage strips are welded to the steel structure below them and then fully coated with anti-rust paint.

[0034] S3: Wooden sheathing installation; Furthermore, step S3 also includes: S301: Installation layout. Before installation, measure the existing building components on the installation surface and modify any parts that do not meet the requirements for wooden sheathing installation. Based on the deviation record, implement targeted corrective measures.

[0035] The starting line of the wooden roofing planks is determined according to the plank layout design. Before the construction of the wooden roofing planks, the starting point of the plank layout is marked on each purlin along the span direction. The line connecting all the starting points is the starting line of the wooden roofing planks, which is perpendicular to the longitudinal axis of the building. At the same time, along the width direction of the wooden roofing planks, according to the plank layout design, a starting point is marked on every few planks as an observation point. The observation points can be used to limit and check the installation and deviation accumulation of the wooden roofing planks along the width direction.

[0036] S302: Apply fire-retardant coating to all six sides of the wooden plywood before installation; S303: Install wooden shingles, ensuring that the boards are tightly interlocked; Furthermore, step S303 also includes: S3031: Fix the side support of the first wooden plank, with the inner edge line of the side support coinciding with the starting line of the wooden plank installation. Use a ruler to locate the position of the middle support and fix the middle support in place. S3032: Use the side bracket to snap the male edge of the wooden board in place, and then fix the side bracket; S3033: Use a ruler to position and fix the middle support of the subsequent wooden planks; S3034: Align the subsequent wooden planks with the support and place them in place. Use the method described in S3031 to ensure that the female side of the rear wooden plank engages well with the male side of the front wooden plank and the corresponding middle support (for the side support). S3035: Repeat steps S3031 to S3033 to install subsequent wooden planks.

[0037] It is important to note that the following checks need to be performed regularly during the installation of the wooden sheathing: (1) Tightness of the interlocking: confirm whether the side bracket fully engages the male edge of the wooden board and whether the female edge of the wooden board fully encloses the side bracket.

[0038] (2) Check the installation deviation. When the deviation exceeds the permissible range, find out the cause in time and make adjustments until it meets the requirements.

[0039] S304: Finishing touches When laying the purlins to the end, if the remaining purlin length is less than one-quarter of the width of the wooden veneer, use the side brackets to hold the male edge of the wooden veneer, then saw off the excess part of the side brackets, and then cover the remaining part with the edge trimming board. When laying the final section, if the remaining purlin length is less than the width of the wooden shingle but more than one-quarter of the width of the wooden shingle, cut off the part of the wooden shingle that extends beyond the purlin and fix it with the middle bracket, and use the side bracket to press down the male edge of the wooden shingle.

[0040] S4: Construction of batten installation; Step S4 also includes: Galvanized thin-walled square tubes were selected as the roofing strips.

[0041] Fix the batten strips to the water flow strips and weld them to each water flow strip from top to bottom, then perform rust prevention treatment.

[0042] When welding battens, the best right angle should be selected as the upper edge, and the battens should be welded firmly according to the marked position. The battens should be staggered at the horizontal joints, and the upper edge of the battens should be in a straight line. The joint should be on the water strip, and the joints between the upper and lower rows should be staggered.

[0043] When there is a drainage ditch in the roof, battens should not be installed within the area of ​​the drainage ditch, and the drainage ditch should be installed first and then the battens should be installed. At the same time, the length of the tiles on the battens extending into the ditch should be controlled between 50-70mm. Two tile strips should be installed at the eaves, and the height of the tile strips at the eaves should be at least 60mm from the bottom of the water strip upwards.

[0044] When using eaves tiles to finish the gable end of a double-sloped roof, the end of the batten should be at least 40mm from the edge of the eaves to allow for the installation of an additional water-guiding strip. This additional water-guiding strip is connected to the end of the batten and should be at least 10mm from the edge of the eaves.

[0045] Based on the outline (i.e. center line) of the sloping ditch, place a positioning line on each side parallel to the outline. The area between the two positioning lines is both the area for installing the drainage ditch and the reference line for installing the additional water-guiding strip. Each positioning line should be at least 160mm away from the center line.

[0046] The drainage ditch can be made of aluminum and fixed to the additional water-guiding strips and tile strips, with the upper and lower overlap of the aluminum drainage ditch not less than 150mm. Alternatively, it can be constructed as a concealed ditch by cutting and splicing tiles.

[0047] S5: Roofing tile installation; Step S5 also includes: S501: Before laying the tiles, draw a longitudinal straight line as the tile laying reference to ensure that the tile seams are vertical; Furthermore, the specific procedures are as follows: (1) Mark a line at least 50mm away from the eaves on both sides of the tile strip. This line is an alignment line and is perpendicular to the eaves line.

[0048] (2) Lay two tiles on the first parallel line and the center line, and align the edge ribs of the two tiles with the alignment line. Then, use the edge ribs of the two tiles to draw a longitudinal straight line, or calculate the position of the edge ribs according to the width of the two tiles and draw a longitudinal straight line.

[0049] (3) When laying the tiles, align them in a longitudinal straight line so that the roof tiles are horizontal, the tile seams are vertical, and the diagonal lines are aligned.

[0050] S502: Pre-laying; During the pre-laying process, especially for large-area double-sloped roofs, the effective width of the main tile is distributed according to the horizontal length of the roof, and the end is adjusted to a whole tile or half tile by using the adjustment distance of the left and right overlapping edge bars of the tile (usually about 4mm). S503: Formal Tile Laying. When laying the first row of tiles, the tiles should extend 50mm to 75mm beyond the drainage ditch. The tile claws should be tightly fastened to the batten and ensure a tight fit with the left and bottom tiles in the groove. Starting from the lower right corner of the eaves, lay the tiles from right to left and from bottom to top. For horizontal overlaps, the left tile should overlap the right tile, with a minimum overlap length of 40mm. The overlap should be stable after the tiles are interlocked. The tile claws of each main tile must be tightly fastened to the batten and aligned with the tile seams. For vertical overlaps, the front end of the upper tile should overlap the rear end of the lower tile, with a minimum overlap length of 75mm. The overlap should cover the self-locking diagonal triangle of the tile.

[0051] Flat tiles should be staggered by 1 / 2 overlap.

[0052] During the tile-laying process, always pay attention to the verticality of the tile surface and corrugations; tiles that do not meet quality requirements should not be laid.

[0053] It is important to note that the first row of tiles at the eaves, the tiles at the gable, and the tiles at the ridge must all be fixed. The remaining tiles can be fixed in a staggered pattern. The tiles should be nailed directly to the battens using self-tapping dovetail screws. Depending on the tile type, self-tapping dovetail screws with a length of 5 to 7.5 cm can be used to fix the tiles.

[0054] Furthermore, to ensure the tiles are flat and straight, a diagonal line can be drawn from the ridge to the eaves, and then the tiles can be laid one by one from bottom to top. When laying the tiles, align the diagonal line with the lower right corner of the first tile on the ridge, then with the lower right corner of the second tile in the second row, the third tile in the third row, and so on, until the lower right corner of the eaves tile, ensuring they are all in a straight line. This will make the tile grooves straight, neat, and aesthetically pleasing.

[0055] Furthermore, the tiles should be overlapped in the direction of the prevailing wind to prevent leaks, and the first row of tiles at the eaves should be laid in a straight line. Tiles at the gutter should be cut according to the width and slope indicated by a chalk line. Tiles on a full slope should be flat, arranged horizontally and vertically, without any warped corners or gaps.

[0056] Further, special handling is required for specific areas. When encountering ridges or gutters, the tiles need to be cut. The outer edge of the tile should be cut to a line parallel to the ridge (at least 20mm from the center line) to prevent problems with later installation due to excessive size. First, hang the whole tile (or select a usable half tile, or a tile with a missing corner or edge), ensuring that the overlap width at the gutter edge is not less than 150mm. Mark the whole tile (or half tile, or tile with a missing corner or edge) with an ink line, number it, then cut along the ink line, and finally hang it in numerical order.

[0057] Hang the flat tiles along the ridge using the method described above. In special areas, ensure that the tiles overlap tightly and that the overlap between the ridge tiles and the flat tiles on each side is no less than 40mm. Smooth the grout joints on both sides of the ridge tiles, but do not grout the surface of the overlapping joints.

[0058] Furthermore, the installation of the ridge tiles is as follows: (1) Ridge tiles: When hanging flat ridge and sloping ridge tiles, a long line should be stretched to lay them flat and straight. The construction lines of the ridge and sloping ridge should be used as the reference line to fix the support frame and the support. Using the height of the support frame measured during pre-laying, adjust the support frame and fix it to the water strip with nails. Then fix the galvanized thin-walled square tube to the support frame. The spacing of the support frame should not be less than 500mm.

[0059] (2) Installation of ridge tiles and flat tiles.

[0060] The overlap between ridge tiles and flat tiles should be no less than 40mm on each side; the joints of flat tiles should be aligned with the prevailing wind direction; the installation of ridge tiles should begin with the end ridge tiles and proceed sequentially to the end ridge tiles.

[0061] The installation of the ridge tiles begins at the ridge cap and proceeds from bottom to top, overlapping to the ridge position.

[0062] At the junction of flat tiles and ridge tiles, the gaps can be filled and smoothed with mortar containing crack-resistant fibers, so that the laid flat and ridge tiles are straight and without any warping or undulation.

[0063] Three-way ridge tiles are installed at the intersection of three directions of the roof, that is, at the intersection of the two-way sloping ridges and the main ridge.

[0064] Four-way ridge tiles are installed on four-way roofs, multi-way roofs, and at junctions with excessively large angles of inclination.

[0065] Three-way and four-way ridge tiles should be bonded with high-grade cement mortar or adhesive.

[0066] It is important to note that when tiles need to be cut, the fixation of the cut tiles needs to be strengthened. Using tile cutter clips can effectively ensure the stability of the tiles and ensure their safe use. When fixing the tile cutter clips, wrap the steel wire around the support and fix it to the opposite side of the support, and then wrap it around the screw. Then tighten the screw on the support, paying attention to the direction of force. After fixing, the tile should be secure and not loose.

[0067] S6: Detail node processing.

[0068] Step S6 also includes: For the ridge treatment, this application employs a wooden support frame for the ridge tiles (including the main ridge and the sloping ridges). After the batten installation is completed, the wooden support frames are fixed to the batten strips, with a spacing of no less than 500mm between the support frames. Then, galvanized thin-walled square tubes (for fixing the ridge tiles) are fixed to the wooden support frames. Ventilation and waterproof membrane is then pasted along the ridge direction, followed by the installation of the ridge tiles on the galvanized thin-walled square tubes. To ensure straight ridge tile installation, lines are marked at both ends of the ridge during the laying of the ridge tiles, and the installation is strictly carried out according to these lines.

[0069] For the eaves treatment, metal fascia boards are installed on the existing steel structure eaves to form a base, and then painted black. Additionally, drainage strips can be stacked above the longitudinal steel joists, with each layer tightly fitted to the layer below. The final layer extends to the drainage strip on the concrete roof, maintaining the same elevation and slope. The overhang of the tiles at the eaves is between 50mm and 70mm.

[0070] The process for treating the retaining wall extending above the roof is as follows: (1) Install the tiles to the retaining wall normally.

[0071] (2) After hanging the last main tile, stick the self-adhesive waterproof membrane to the end of the last main tile and roll the waterproof membrane up to the wall.

[0072] (3) When the retaining wall is high enough, the fold of the waterproof membrane can be placed at the end of the last tile. Peel off the bottom release film of the waterproof membrane and apply it fully to the retaining wall. When laying, gradually lay it from the fold to both sides. A roller can be used to press it to ensure that there are no air pockets between the waterproof membrane and the adhesive surface. Uneven areas can be pressed by hand to achieve full adhesion of the waterproof membrane.

[0073] (4) The waterproofing and roofing tile pasting methods are the same as above.

[0074] (5) The pressure strip can be fixed after the flexible waterproof membrane is pasted on the front. The pressure strip is usually made of aluminum and the color is the same as the waterproof membrane.

[0075] (6) Align the crease at the top of the fixing area of ​​the strip with the edge of the waterproof membrane so that the nails fixing the strip can also fix the flexible waterproof membrane.

[0076] (7) When using dovetail self-tapping screws to fix the pressure strip, a self-tapping screw must be installed at the edge of the pressure strip.

[0077] (8) Apply weather-resistant sealant to the top of the aluminum pressure strip to seal it. The sealant should be continuous and full. There should be no gaps or excessive thickness in the application to prevent water leakage or seepage.

[0078] For drainage ditch treatment, after marking the lines according to the design width, install the aluminum drainage ditch, ensuring that the overlap length of the upper and lower drainage ditches is not less than 150mm.

[0079] Furthermore, this application uses wooden roofing boards instead of precast concrete slabs. While this reduces the roof load, wood is sensitive to humidity. If the roof tiles are made of inexpensive sheet metal, there is a risk of deformation over long-term use. For example, snow in winter can deform the tiles, or hail can dent them, causing a bulge on the side of the tile facing the wooden roofing board. Once the tile collapses, condensation caused by temperature changes will accumulate along the bulge and drip onto the wooden roofing board, leading to wood decay and mold, weakening the base layer, and potentially corroding the adjacent galvanized steel. Because there are battens above the wooden roofing board, there is a certain distance between the tiles and the wooden roofing board, which also provides conditions for condensation and tile deformation. To address the aforementioned issues, we added an insulating layer to the top surface of the wooden roofing sheets to reduce deformation of the sheet metal roofing sheets under extreme weather conditions such as hail and snow. This insulating layer can be a mesh-like product made of plastic, which can be placed directly on the upper surface of the wooden roofing sheets, or fixed to the upper surface with screws or adhesive. Plastic products have advantages such as being lightweight, rust-free, inexpensive, and easily cut to size. When using it, the mesh openings should face the roofing sheets. The mesh structure can support the roofing sheets when they deform, thereby reducing deformation of the sheet metal roofing sheets under extreme weather conditions.
