[0005] 1. Since there are differences between the actual parameters and the standard parameters of the stairs, at least part of the actual circular-arc stair built does not extend around the reference center of the standard stair radius set in the architectural drawings, so the circular-arc stair after the tile is pasted is not a standard circular-arc stair, which makes the circular-arc stair not beautiful;

[0066] As shown in Figures 1 to 14 , Figure 19 and Figure 20 , a circular stair reference circle center positioning method, comprising the following steps:

[0067] S1. Install a circle center positioning rod 12 for positioning the reference circle center position of the circular stair on one of the steps 10 of the circular stair, the circle center positioning rod 12 includes a fixed end 121 and a positioning end 122, the fixed end 121 is fixedly connected to the step 10 and close to the external corner 103 of the step 10, and the positioning end 122 extends along the edge of the external corner 103 to the inside of the circular stair and protrudes from the inside surface of the circular stair;

[0068] S2. Perform step S1 on at least one of the other steps 10 of the circular stair;

[0069] S3. Observe the intersection of the projections of the plurality of circle center positioning rods 12 on the ground, and determine the reference circle center point on the ground.

[0070] Before the decoration construction is carried out, the reference circle center point of the circular stair is determined by using the plurality of circle center positioning rods 12, and then the reference circle center point is used as a reference standard for measurement and calculation, so as to measure and calculate the accurate parameters of the circular stair after the decoration is completed, so that each step 10 has the same parameters after the decoration is completed, and a batch of standard size ceramic tiles are manufactured according to the parameters of the steps 10. The ceramic tiles can be directly laid after being transported to the construction site. The circular stair reference circle center positioning method in the present application is beneficial to save economic cost, labor cost and time cost, reduce pollution to the construction site, and make the circular stair after decoration more beautiful.

[0071] In some specific embodiments, step S1 includes the following steps:

[0072] S1-1. A center positioning base 11 for fixing the center positioning rod 12 is installed on the external corner 103 of one step 10 of the circular stair, the center positioning base 11 comprises a first fixing plate 112 and a second fixing plate 113 fixedly connected, the first fixing plate 112 and the second fixing plate 113 intersect and form an installation included angle matching the external corner 103, the first fixing plate 112 is an iron plate 111 or the first fixing plate 112 is fixedly connected with the iron plate 111, the first fixing plate 112 is fixed on the tread 101 of the step 10 and / or the second fixing plate 113 is fixed on the nosing 102 of the step 10, and the iron plate 111 is at least partially laid on the tread 101;

[0073] S1-2. A magnet is arranged on the outer peripheral wall close to the fixed end 121 of the center positioning rod 12, the center positioning rod 12 is fixed on the upper side of the iron plate 111 by the magnet, and the center positioning rod 12 is moved to adjust the center positioning rod 12 to extend along the edge of the external corner 103 to the inner side of the circular stair and protrude from the inner side of the circular stair.

[0074] The center positioning rod 12 is fixed on the tread 101 of the step 10 by the magnet and the iron plate 111, which facilitates the movement of the center positioning rod 12 to adjust the position of the center positioning rod 12.

[0075] Specifically, three positioning base fixing holes 114 are arranged on the first fixing plate 112 and the second fixing plate 113, the first fixing plate 112 is fixedly connected on the tread 101 of the step 10 through the three positioning base fixing holes 114 arranged thereon, and the second fixing plate 113 is fixedly connected on the nosing 102 of the step 10 through the three positioning base fixing holes 114 arranged thereon. The first fixing plate 112 is an iron plate 111, and when the center positioning base 11 is installed, the iron plate 111 is at least partially laid on the tread 101.

[0076] The magnet arranged on the center positioning rod 12 is specifically a magnet particle 123. Two magnet particles 123 are arranged on the outer peripheral wall of the center positioning rod 12 along the axial direction of the center positioning rod 12. The magnet is arranged on the center positioning rod 12 in the form of the magnet particle 123, so that the construction personnel does not need to use too much force when moving the center positioning rod 12, thereby reducing the possibility of the center positioning rod 12 being seriously deviated due to excessive force of the construction personnel, and facilitating the adjustment of the circular positioning rod.

[0077] Further, the first fixed plate 112 is an iron plate 111, and the iron plate 111 is arranged in a T shape with the second fixed plate 113, one side of the second fixed plate 113 being fixedly connected to the iron plate 111, so that when the center positioning base 11 is fixed on the external corner 103, a part of the iron plate 111 is laid on the tread 101, and the other part extends along the width direction of the tread 101 and protrudes from the tread 101.

[0078] Generally, when the center positioning base 11 is arranged on the external corner 103 of the stair tread 10, the tread 101 and the kick plate 102 on the stair tread 10 are not yet tiled with ceramic tiles. After the ceramic tiles are tiled on the kick plate 102, the ceramic tiles on the kick plate 102 can be regarded as a part of the kick plate 102, and the edge of the kick plate 102 will be expanded outward, that is, the position of the external corner 103 will move outward. The iron plate 111 is arranged in a T shape with the second fixed plate 113, so that when the center positioning base 11 is fixed on the external corner 103, a part of the iron plate 111 is laid on the tread 101, and the other part extends along the width direction of the tread 101 and protrudes from the tread 101. The center positioning rod 12 can be arranged on the part of the iron plate 111 protruding from the tread 101, so that the position of the center positioning rod 12 is closer to the edge position of the external corner 103 after the ceramic tiles are tiled, which is beneficial to improve the construction quality.

[0079] Further, the second fixed plate 113 is also an iron plate.

[0080] In some other embodiments, the center positioning rod 12 can also be directly fixed on the stair tread 10 without the center positioning base 11.

[0081] In some specific embodiments, the step S3 comprises the following steps:

[0082] S3-1. observing the intersection of the projections of the plurality of center positioning rods 12 on the ground, and finding the intersection point through which the most center positioning rods 12 project as a preset reference point;

[0083] S3-2. setting the number of the center positioning rods 12 as b, finding the center positioning rods 12 whose projections do not pass through the preset reference point, setting the number of the center positioning rods 12 whose projections do not pass through the preset reference point as a, if a>25%b, performing step S3-3; if a≤25%b, performing step S3-5;

[0084] S3-3. moving or swinging the center positioning rods 12 whose projections do not pass through the preset reference point along the width direction of the tread 101 to adjust the positions of the center positioning rods 12 within the adjustment range;

[0085] S3-4. repeating steps S3-1 to S3-2;

[0086] S3-5. Mark the preset reference point on the ground as the reference center point.

[0087] Due to the arc-shaped stair in the blank state, some steps 101 may have parameters deviating from the standard parameters by too large a margin. Therefore, the construction personnel can adjust the center positioning rod 12 to extend along the original external corner 103 edge of the step 10 as much as possible, so that the finally positioned reference center point is closer to the center point of the arc-shaped stair used as the reference when the arc-shaped stair is built, which is conducive to further improving the decoration effect.

[0088] When observing, the construction personnel needs to observe the projection of the center positioning rod 12 on the ground from above the stair.

[0089] As for the relationship between the number a and the number b, an example is given here: eight center positioning rods 12 are arranged on the arc-shaped stair, i.e., b = 8. If a = 1, a < 25% b, step S3-5 can be directly performed; if a = 2, a = 25% b, step S3-5 can be directly performed; if a = 3, a > 25% b, S3-3 needs to be performed. According to the method of measuring the reference center point, the size parameters of each step after decoration are calculated, and then a batch of ceramic tiles with uniform size are made according to the size parameters of the steps. In the process of laying ceramic tiles for decoration, most of the ceramic tiles can be directly laid on the steps, and only a small part of the ceramic tiles may need to be slightly processed, which is conducive to improving the efficiency of decoration construction and reducing the pollution of the construction site.

[0090] In some other embodiments, according to the completion quality of the blank stair, the construction personnel can re-set the ratio between a and b to directly perform step S3-5. For example: under the premise that the completion quality of the blank stair is good, it can be set that if a > 20% b, step S3-3 is performed; if a ≤ 20% b, step S3-5 is performed. Under the premise that the completion quality of the blank stair is poor, it can be set that if a > 30% b, step S3-3 is performed; if a ≤ 30% b, step S3-5 is performed.

[0091] The adjustment range of the center positioning rod 12 in step S3-3 is also obtained according to the experience of the construction personnel: in the face of a step 10 with poor completion quality and an external corner 103 parameter deviating too much in the arc-shaped stair, the construction personnel can infer the actual completion position of the external corner 103 of the step 10 according to experience, and the construction personnel can move the center positioning rod 12 to the vicinity of the actual completion position of the external corner 103 of the step 10, and then perform S3-4.

[0092] In actual construction environment, due to the uneven quality of the rough stair, in many cases, the intersection of the projections of multiple center positioning rods 12 can have many points, combined with the actual situation, if these intersection points are relatively close, a reference center point can also be obtained according to these intersection points. For example, referring to Figure 19 and Figure 20 , eight center positioning rods 12 are arranged on the circular stair, there are twelve intersection points between the projections of these center positioning rods 12, but the distance between these intersection points is very close, the distance between each other is not more than three centimeters, the three outermost intersection points in these intersection points are used to form a triangle, and the other intersection points are enclosed in the triangle, a point in the triangle is selected as the reference center point, the reference center point should be appropriately close to the area where the intersection points are relatively dense, such as the h point in Figure 20 . In some other embodiments, the construction personnel can use the three outermost intersection points to form a circle, and then use the center of the circle as the reference center point.

[0093] In some specific embodiments, the reference center positioning method of the circular stair further includes the following steps:

[0094] S4. A hanging line assembly is installed on the circular stair, the hanging line assembly includes a hanging line base 21, a supporting vertical rod 221, a supporting horizontal rod 222 and a hanging line structure 23, the supporting vertical rod 221 is fixedly connected to the hanging line base 21 vertically, the supporting horizontal rod 222 is fixedly connected to the supporting vertical rod 221 and is perpendicular to the supporting vertical rod 221, one end of the supporting horizontal rod 222 is provided with the hanging line structure 23, the hanging line base 21 is fixedly connected to the step 10 at the top of the circular stair, and the hanging line structure 23 is located directly above the reference center point;

[0095] S5. A reference line fixing structure is fixedly arranged on the ground and located directly below the hanging line structure 23, the reference line fixing structure includes a reference line binding structure;

[0096] S6. A circular stair reference line 201 is hung on the hanging line structure 23 and bound to the reference line binding structure, so that the circular stair reference line 201 extends vertically and is located directly above the reference center point.

[0097] The hanging line assembly is arranged on the stair to avoid hanging the line on the top of the building, which will not damage the wall. The position of the reference center point is stereoscopic by using the circular stair reference line 201, which is convenient for measuring and constructing the stair.

[0098] In some specific embodiments, in step S4, the hanging line assembly is arranged on the tread plate 101 or the kick plate 102 of the step 10 at the top of the circular stair, or is arranged on the inner side surface close to the top of the circular stair.

In use, since the direction of the support horizontal rod 222 is required, the situation that the support horizontal rod 222 is directed to the specified direction but the first vertical rod connecting screw 2212 fails to be tightened on the connecting pipe 2141 may occur. At this time, the first vertical rod connecting nut 2213 is needed to tighten the first vertical rod connecting screw 2212 on the connecting pipe 2141, so that the support vertical rod 221 is relatively fixed with the hanging line base 21.

[0102] The support vertical rod 221 is provided with a horizontal rod mounting pipe 2211 extending transversely; the hanging line assembly further comprises a first horizontal rod 2221 connecting screw rod, one end of the horizontal rod mounting pipe 2211 is provided with a screw rod mounting plate 22111, the screw rod mounting plate 22111 is arranged on the inner side of the horizontal rod mounting pipe 2211 and blocks the opening of one end of the horizontal rod mounting pipe 2211, the screw rod mounting plate 22111 is provided with a screw rod connecting screw hole 22112, the screw rod connecting screw hole 22112 is in communication with the internal space of the horizontal rod mounting pipe 2211, and the first horizontal rod 2221 connecting screw rod is screw-connected to the screw rod connecting screw hole 22112; one end of the horizontal rod mounting pipe 2211 away from the screw rod mounting plate 22111 is provided with a support horizontal rod 222, the support horizontal rod 222 is partially located in the horizontal rod mounting pipe 2211, one end of the first horizontal rod 2221 connecting screw rod close to the support horizontal rod 222 is provided with a clamping piece, one end of the support horizontal rod 222 close to the first horizontal rod 2221 connecting screw rod is provided with a buckling piece 22212 matched with the clamping piece, and the clamping piece is clamped on the buckling piece 22212, so that when the first horizontal rod 2221 connecting screw rod is rotated, the support horizontal rod 222 can move along the extension direction of the horizontal rod mounting pipe 2211. The purpose is to adjust the length of the support horizontal rod 222 extending out, so as to adjust the position of the hanging line structure 23. Specifically, the outer diameter of the support horizontal rod 222 matches the inner diameter of the horizontal rod mounting pipe 2211, and the support horizontal rod 222 has substantially no radial movement space in the horizontal rod mounting pipe 2211.

The support horizontal rod 222 is divided into multiple horizontal rods that can be connected and disconnected, which is conducive to adapting to various hanging line requirements and facilitating carrying.

[0104] The support cross rod 222 further comprises a third cross rod 2223, both ends of the third cross rod 2223 are coaxially provided with a third cross rod 2223 connecting screw rod and a second cross rod 2222 connecting screw hole respectively, the third cross rod 2223 connecting screw rod is screw-connected in the first cross rod 2221 connecting screw hole, and the second cross rod 2222 connecting screw rod is screw-connected in the second cross rod 2222 connecting screw hole. According to the actual situation of the construction site, one or more third cross rods 2223 can be arranged between the first cross rod 2221 and the second cross rod 2222, so as to adjust the length of the wire hanging structure 23.

[0106] After the wire hanging and the heavy object is bound at the lower end of the reference line 20, the reference line 20 will first undergo a period of swinging. The first reference line limiting plate 252 and the second reference line limiting plate 254 can limit the swinging position of the reference line 20, so that the swinging time of the reference line 20 is shortened. After the reference line 20 stops swinging, the first reference line limiting plate 252 is adjusted along the extension direction of the first long hole 253, so that the side wall of the first reference line limiting plate 252 just touches the reference line 20; the second reference line limiting plate 254 is adjusted along the extension direction of the second long hole 2521, so that the side wall of the second reference line limiting plate 254 just touches the reference line 20.

Since the reference line fixing base 26 needs to be fixed to the ground surface by expansion screws, it is only suitable for construction sites where the ground surface has not yet been paved with tiles.

[0109] In some embodiments, in step S2, one step 10 is arranged between the adjacent steps 10 provided with the center positioning rod 12, which is beneficial to obtain the reference center point corresponding to the actual shape of the arc-shaped staircase.

[0110] As shown in Figures 1 to 20 , the present application further provides a special-shaped staircase positioning method comprising the arc-shaped staircase reference center positioning method.

[0111] In some embodiments, the special-shaped staircase positioning method further comprises the following steps:

[0112] S6. Perform steps S1 to S3 in the arc-shaped staircase reference center positioning method to find the reference center point corresponding to each arc-shaped staircase in the special-shaped staircase.

[0113] The special-shaped staircase refers to a staircase structure composed of multiple arc-shaped staircases or a combination of arc-shaped staircases and straight staircases. For multiple arc-shaped staircases, since the reference center points of each arc-shaped staircase are different and the radii are also different, the reference center points of each arc-shaped staircase need to be confirmed first before the next construction.

[0114] Referring to Figure 18 , the special-shaped staircase shown in the figure has three arc-shaped staircases, and e, f, and g in the figure are the reference center points corresponding to the three arc-shaped staircases, respectively.

[0115] In some embodiments, the special-shaped staircase positioning method further comprises the following steps:

[0116] S7. Install the hanging line assembly on the special-shaped stairs, the hanging line assembly comprising one or more hanging line bases 21, one or more support vertical rods 221, a plurality of support horizontal rods 222, and a plurality of hanging line structures 23, one hanging line base 21 being fixedly connected with one support vertical rod 221 extending vertically, one support vertical rod 221 being fixedly connected with one or more support horizontal rods 222 and the support horizontal rods 222 being perpendicular to the corresponding support vertical rod 221, and the hanging line structure 23 being arranged at one end of the support horizontal rod 222 and one support horizontal rod 222 being provided with one hanging line structure 23, the plurality of hanging line structures 23 comprising a plurality of circular-arc stair reference line hanging line structures 231, the hanging line base 21 being fixedly connected to the steps 10 at the top of the circular-arc stairs, and the plurality of circular-arc stair reference line hanging line structures 231 being located one by one above the plurality of reference circle center points;

[0117] S8. Fixedly arrange a plurality of reference line fixing structures on the ground and make the plurality of reference line fixing structures correspond one by one to the plurality of hanging line structures 23 below, the reference line fixing structure comprising a reference line binding structure;

[0118] S9. Arrange a plurality of reference lines 20 one by one on the plurality of hanging line structures 23, the plurality of reference lines 20 comprising a plurality of circular-arc stair reference lines 201, the circular-arc stair reference line 201 being bound to the corresponding reference line binding structure, the circular-arc stair reference line 201 extending vertically and being located above the corresponding reference circle center point.

[0119] For the multi-segment circular-arc stairs built based on different reference circle centers, the plurality of reference circle center points are stereoscopicized by using the hanging line assembly and the plurality of circular-arc stair reference lines 201, which facilitates the measurement and construction of the stairs.

[0120] Specifically, the hanging line assembly further comprises a secondary support vertical rod 24221, the upper end of the support vertical rod 221 being provided with a first vertical rod connecting screw hole 2214, the lower end of the secondary support vertical rod 24221 being provided with a second vertical rod connecting screw rod 241, the second vertical rod connecting screw rod 241 being screw-connected into the first vertical rod connecting screw hole 2214, and the secondary support vertical rod 24221 being used for arranging the support horizontal rod 222; the upper end of the secondary support vertical rod 24221 being provided with a second vertical rod connecting screw hole 242, the second vertical rod connecting screw hole 242 being used for connecting other secondary support vertical rods 24221, which is conducive to arranging the plurality of reference lines 20 and is particularly suitable for the special-shaped stairs combined by a plurality of stair structures. The first vertical rod connecting screw rod 2212 and the second vertical rod connecting screw rod 241 are of the same specification, and the first vertical rod connecting screw hole 2214 and the second vertical rod connecting screw hole 242 are of the same specification.

[0121] The sub-support vertical rods 24221 are arranged such that multiple support horizontal rods 222 can be arranged on one support vertical rod 221, that is, multiple hanging line structures 23 can be arranged on one support vertical rod 221, and multiple reference lines 20 can be hung on one support vertical rod 221, thereby reducing the number of hanging line bases 21, improving construction efficiency, and protecting the stair structure.

[0122] In some other embodiments, multiple hanging line bases 21 and multiple support vertical rods 221 can be arranged, and the number of hanging line bases 21 is less than the number of hanging line structures 23.

[0123] In some other embodiments, multiple hanging line bases 21 and multiple support vertical rods 221 can be arranged, and the number of hanging line bases 21 is consistent with the number of hanging line structures 23, and the multiple hanging line bases 21 correspond to the multiple hanging line structures 23 one by one.

[0124] In some specific embodiments, in step S7, the multiple hanging line structures 23 further include multiple straight stair reference line hanging line structures 232; and in step S9, the multiple reference lines 20 further include multiple straight stair reference lines 202. The straight stair reference lines 202 are bound to the corresponding reference line binding structures, such that each straight stair in the special-shaped stair is provided with multiple straight stair reference lines 202 located in the same plane, and the side finish surface of the straight stair is parallel to the plane in which the multiple straight stair reference lines 202 are located. For the special-shaped stair with straight stairs, the multiple straight stair reference lines 202 are used to position the side finish surface of the straight stair, thereby facilitating subsequent construction.

[0125] The side finish surface of the straight stair refers to the side surface of the straight stair after construction. In the construction process, the construction team first finds the straight stair positioning line in the house, and the vertical plane in which the straight stair positioning line is located is parallel or perpendicular to the side finish surface of the straight stair. Therefore, the plane in which the multiple straight stair reference lines 202 are located is parallel or perpendicular to the vertical plane in which the straight stair positioning line is located: when the overall extension direction of the straight stair is parallel to the straight stair positioning line, the plane in which the multiple straight stair reference lines 202 are located is parallel to the vertical plane in which the straight stair positioning line is located; and when the overall extension direction of the straight stair is perpendicular to the straight stair positioning line, the plane in which the multiple straight stair reference lines 202 are located is perpendicular to the vertical plane in which the straight stair positioning line is located.

[0126] Specifically, each straight stair in the special-shaped stair is provided with two straight stair reference lines 202.

[0127] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made based on the inventive concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
