Description

Technical Field

[0001] The invention relates to the technical field of area measurement, and in particular to a method for surveying and measuring the area of ​​a house. Background Art

[0002] House area measurement refers to the area obtained by on-site survey, drawing and calculation of the building by the developer, who, after the completion and acceptance of the commercial housing and the approval of the relevant engineering planning authorities, entrusts a house surveying and mapping agency with surveying and mapping qualifications in accordance with national regulations, with reference to drawings, forecast data and national surveying and mapping regulations. It is the legal basis for the developer and the owner, and the final basis for the owner to apply for property rights certificate, settle property fees and related expenses.

[0003] In the measurement of house area, there are a large number of corner areas, namely triangular areas, in the house. The existing measurement method is that personnel measure the length and width of the corners respectively, and then calculate the area of ​​the corners. However, this measurement method is not convenient for measuring corners at different angles. For this reason, the patent with application number CN202222330912.8 proposes a corner device for rough measurement of house area. During operation, the staff records the extended length of the measuring rod and the longest distance between two telescopic measuring rulers. Since the angle between the slide tube one and the slide tube two is 90 degrees, according to the triangle area calculation formula, the staff only needs to multiply the extended length of the measuring rod by the longest distance between the two telescopic measuring rulers to obtain the area of ​​the corner area. The device can adjust the angle of the rotating rod one, the extended length of the measuring rod and the length of the two telescopic measuring rulers according to different angles, so as to facilitate the staff to quickly calculate the area of ​​the corner areas at different angles.

[0004] However, it has certain defects. The sliding pipe 1 and the sliding pipe 2 need to fully cover the opposite sides of the corners in the triangular area. As a result, if a larger triangular area is measured, the lengths of the sliding pipe 1 and the sliding pipe 2 are too large, resulting in the overall equipment being too large. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a housing area surveying and measuring method, which solves the problem in the prior art that when measuring a triangular area of ​​a larger area, the lengths of sliding pipes one and two are too large, resulting in an oversized overall device.

[0006] To achieve the above purpose, the present invention is implemented by the following technical scheme: a housing area surveying and measuring method, comprising the following steps: Step 1: Divide the area inside the house into square areas and triangular areas; Step 2: Use an angle measuring device to equally divide the angle between the two walls forming the triangular area, so that the triangular area is divided into two right-angled small triangular areas, the two right-angled small triangular areas are similar triangles, and obtain the angle data of the angle between the two walls of the triangular area through the angle measuring device; Step 3: Use a length measuring device to measure the length of the wall that is the hypotenuse of the two right-angled small triangles; Step 4: Obtain the areas of the two small right-angled triangles through the angle data and length data, and calculate the total area of ​​the house through the areas of the two small right-angled triangles and the area of ​​the square area.

[0007] Furthermore, the angle measuring device comprises: A main frame, wherein a slidable U-shaped platform is provided on the main frame along the length direction; A rectangular frame structure, wherein two parallel sides of the rectangular frame structure are respectively a bonding plate and a detection plate; the rectangular frame structure is provided with two groups; one end of the intersection of the two groups of detection plates is rotated and arranged on a U-shaped carrier to form a V-shaped structure with a variable angle, and the angle of the two groups of detection plates represents the angle of the extension line of the two groups of bonding plates; By pushing the U-shaped carrier, the two sets of rectangular frame structures can be brought close to the wall, and the bonding plate can be completely attached to the wall.

[0008] Furthermore, the other two sides of the rectangular frame structure are connecting plates, and an I-beam is provided between the bonding plate and the detection plate to enhance the stability of the bonding plate and the detection plate.

[0009] Furthermore, a tension spring is fixed between two adjacent connecting plates, and the angle formed by the tension spring in a natural state is close to 180°; Pushing the U-shaped platform can make the rectangular frame structure gradually approach the corner of the wall to be detected. The wall applies a thrust to the bonding plate, stretching the tension spring and making the bonding plate gradually fit onto the wall.

[0010] Furthermore, a moving seat is provided on one side of the U-shaped platform away from the corner, a spring is installed between the moving seat and the U-shaped platform, and an inclined push rod is provided on the moving seat; The angle formed by the two detection plates is initially an acute angle; Pushing the moving seat close to the U-shaped platform can enable the moving seat to push the U-shaped platform close to the corner through spring 1, and continue to compress spring 1 after the U-shaped platform is in place, so that the push rod pushes the rectangular frame structure to open.

[0011] Furthermore, the rectangular frame structure further comprises a telescopic rod, which comprises an outer tube fixed to the detection plate, an inner rod with one end fixed to the bonding plate and the other end inserted into the outer tube, and a connecting rod for connecting the inner rods; A spring three is fixedly arranged on one end of the inner rod inserted into the outer cylinder.

[0012] Furthermore, it also includes a protractor, which is installed on the U-shaped platform, and the center of the protractor is located on the rotation center of the two detection plates.

[0013] Furthermore, a row of rollers is provided on one side of the laminating board close to the wall surface, so as to reduce the friction between the laminating board and the wall surface.

[0014] Furthermore, a flat steel is provided at one end of the main frame close to the corner; A main block is arranged at the other end of the main frame, and side limit frames are arranged at both ends of the main block for limiting the flat steel on the center line of the wall corner.

[0015] Furthermore, the side limit frame includes a fixed rod fixed to the side of the main block, an L-shaped sliding rod with one end sleeved in the fixed rod, and a single sliding rod sleeved inside the other end of the L-shaped sliding rod, and the single sliding rod is provided with scale marks.

[0016] The present invention has the following beneficial effects: (1) This house area surveying and measuring method divides the area inside the house into a triangular area and a rectangular area, and divides the triangular area into two small triangular areas. An angle measuring device and a length measuring device are used to separately measure the angle and length parameters of the small triangular area, thereby obtaining the area of ​​the triangular area and accurately knowing the house area.

[0017] (2) In the house area surveying and measuring method, the angle measuring device includes a bonding plate and a detection plate that can form a rectangular frame structure. The bonding plate is bonded to the angled wall. The angle of the detection plate represents the angle of the bonding plate, thereby indirectly representing the angle of the bonding plate. Measuring the angle of the detection plate is more convenient than measuring the angle of the bonding plate, thereby making the angle detection of the device more convenient. The area of ​​the triangular area is calculated by detecting the angle, so that the overall volume of the device is small and easy to carry.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0023] According to the following Figure 1-Figure 22 The housing area surveying and measuring method provided by an embodiment of the present invention is described.

[0024] Embodiment 1: See also Figure 1-Figure 2 The embodiment of the present invention provides a housing area surveying and measuring method, comprising the following steps: Step 1: Divide the area inside the house into a square area F and a triangular area D; Step 2: Use an angle measuring device to equally divide the angle between the two walls forming the triangular area D, so that the triangular area D is divided into two right-angled small triangular areas D1 and D2, the two right-angled small triangular areas D1 and D2 are similar triangles, and obtain the angle data of the angle between the two walls of the triangular area D through the angle measuring device; Step 3: Measure the length of the wall that is the hypotenuse of the two right-angled small triangles by using a length measuring device. The length measuring device mentioned here can be a tape measure or a laser measuring device; Step 4: Obtain the areas of the two small right-angled triangles using the angle data and length data obtained above, and calculate the total area of ​​the house using the areas of the small right-angled triangles and the area of ​​the square area.

[0025] When calculating, if Figure 2As shown in the figure (D, D1, D2, D3, F, β, h, g, c, x, w and u are auxiliary annotations made to facilitate the description of the calculation principle), assuming that the angle between the two walls of the triangular area D obtained by the angle measuring device is 2β, then the three internal angles of the two right-angled small triangular areas D1 and D2 are: 90°, β and 180°-β-90°, and the lengths of the hypotenuses of D1 and D2 (the hypotenuse here is the oblique wall) are measured to be h and g, respectively. For D1, sinβ=c / h, then c=sinβ*h, so Get the length c of the first right-angled side of D1, cosβ=x / h, then x=cosβ*h, and thus get the length x of the second right-angled side of D1, and the area of ​​D1 is S1=(x*c) / 2; for D2, sinβ=w / g, then w=sinβ*g, and thus get the length w of the first right-angled side of D2, cosβ=u / g, then u=cosβ*g, and thus get the length u of the second right-angled side of D2, and the area of ​​D2 is S2=(u*w) / 2, so the area of ​​the two triangular regions is S=S1+S2.

[0026] Reference Figure 2 In fact, in actual measurement, the lengths of h and g are generally different, so a small rectangular area D3 is generally formed, where the length of one side is w and the length of the other side is xu, then the area here S3 = w* (xu).

[0027] According to the area data obtained above, the total area of ​​the house = S1+S2+S3+S4, where S4 is the area of ​​area F.

[0028] Combination Figure 3-Figure 12 As shown, specifically, the above-mentioned angle measuring device includes a main frame 4, a rectangular frame structure and a thrust assembly.

[0029] The main frame 4 is a long strip plate-like structure, on which a slidable U-shaped platform 13 is provided along the length direction, and a rectangular frame structure is assembled on the U-shaped platform 13, two parallel sides of the rectangular frame structure are respectively a bonding plate 31 and a detection plate 33, the bonding plate 31 and the detection plate 33 are always in a parallel state, and there are two groups of rectangular frame structures; one end of the intersection of the two groups of detection plates 33 is rotated and set on the U-shaped platform 13 to form a V-shaped structure with a variable angle, and the angle of the V-shaped structure is the angle formed by the two detection plates 33, and the angle can also represent the angle of the extension lines of the two groups of bonding plates 31. In actual operation, the bonding plate 31 is directly bonded to the two inclined walls of the D area, so the angle of the extension lines of the two bonding plates 31 is the angle of the two inclined walls, and the angle of the two inclined walls can be obtained by measuring the angle of the V-shaped structure formed by the two detection plates 33.

[0030] Therefore, the angle of the detection plate 33 indirectly represents the angle of the bonding plate 31, and it is more convenient to measure the angle of the detection plate 33 than to measure the angle of the bonding plate 31, thereby improving the convenience of angle detection of the device.

[0031] Here, a mounting head 37 is arranged at one end of the detection plate 33 close to the U-shaped platform 13, the two mounting heads 37 are staggered up and down, and a pin shaft 36 is arranged at the center of the two, both ends of the pin shaft 36 are fixed on the U-shaped platform 13, the mounting head 37 is rotatably installed on the pin shaft 36, and the position of the pin shaft 36 is at the intersection of the two detection plates 33.

[0032] In order to enable the above-mentioned two rectangular frame structures to be close to and fit on the wall corner, a thrust assembly is also provided here. The thrust assembly is located on the main frame 4. The thrust assembly can apply pressure to the U-shaped carrier 13 to make the two sets of rectangular frame structures close to the wall and make the bonding plate 31 completely stick to the wall.

[0033] Specifically, a tension spring 11 is fixed between the two adjacent connecting plates 32. The angle formed by the two detection plates 33 in the natural state of the tension spring 11 is close to 180°, preferably 150°. Figure 6 It is the angle of the two detection plates 33 when the tension spring 11 is in the natural state. When the thrust assembly is working, it can push the U-shaped platform 13, so that the rectangular frame structure gradually approaches the corner of the wall to be detected. The wall applies thrust to the bonding plate 31, so that the tension spring 11 is stretched and the bonding plate 31 gradually fits onto the wall.

[0034] Therefore, the present invention can measure the angle between two inclined walls by only pushing the U-shaped platform 13, making the wall angle measurement more convenient.

[0035] Preferably, the other two sides of the rectangular frame structure are connecting plates 32, and an I-beam 34 is provided between the bonding plate 31 and the detection plate 33, which are connected by welding to enhance the stability of the bonding plate 31 and the detection plate 33 so that the detection plate 33 and the bonding plate 31 can maintain a stable parallel state.

[0036] like Figure 2 and Figure 3 As shown, for convenience, a protractor 12 is also included. The protractor 12 is installed on a U-shaped platform 13, and the center of the protractor 12 is located at the intersection of the two detection plates 33, that is, at the position of the pin 36. The angles of the two detection plates 33 can be read on the protractor 12, and the read value is the angle of the two inclined walls.

[0037] Preferably, in order to reduce the wear of the laminating plate 31 on the wall, a row of rollers 35 is provided on the side of the laminating plate 31 close to the wall to reduce the friction between the laminating plate 31 and the wall.

[0038] Furthermore, in order to keep the main frame 4 located at the midline of the angle between the two inclined walls, a flat steel 41 is provided at one end of the main frame 4 close to the corner. The thickness of the flat steel 41 is relatively small and can be as close to the corner point as possible. A main block 10 is provided at the other end of the main frame 4. Side limit frames 2 are provided at both ends of the main block 10 for limiting the flat steel 41 on the midline of the corner. The side limit frames 2 can be tightly attached to the wall. Since the two side limit frames 2 are equal in length, the main block 10 can be limited to the midline of the angle, so that the flat steel 41 and the main frame 4 are both located on the midline.

[0039] In this embodiment, the side limit frame 2 includes a fixed rod 21 fixed to the side of the main block 10, an L-shaped sliding rod 22 with one end sleeved in the fixed rod 21, and a single sliding rod 23 sleeved inside the other end of the L-shaped sliding rod 22. The single sliding rod 23 is provided with scale marks. By adjusting the exposed length of the single sliding rod 23 on the L-shaped sliding rod 22 and the exposed length of the L-shaped sliding rod 22 on the fixed rod 21, the overall length can be adjusted to adapt to walls at different angles. The L-shaped sliding rod 22 is provided to reserve a certain length for the main frame 4 while reducing the lateral length of the entire side limit frame 2, thereby reducing the size of the device.

[0040] Specifically, guide rails 42 are provided on both sides of the main frame 4 mentioned above, and second sliders 131 are provided on both sides of the U-shaped platform 13 . The second sliders 131 are adapted to the guide rails 42 , so that the U-shaped platform 13 can have freedom in the length direction of the main frame 4 .

[0041] The thrust assembly mentioned above actually has multiple pushing modes, and two pushing modes are given below.

[0042] Combination Figure 3 and Figure 7 It is a first thrust assembly: a guide groove 43 is opened on the upper surface of the main frame 4, and the thrust assembly is a thrust assembly 5, which includes a screw rod 51 rotatably assembled in the guide groove 43, a nut 53 is arranged on the screw rod 51, the nut 53 is fixedly connected to the U-shaped platform 13, and a handwheel 52 is installed at one end of the screw rod 51 close to the nut 53. By rotating the handwheel 52, the screw rod 51 can be driven to rotate, and then the nut 53 drives the U-shaped platform 13 to move horizontally; in this embodiment, it is also necessary to set a support leg 1 below the fixed rod 21 and below the main frame 4, and preferably a leveling bolt is set below the support leg 1 to maintain the balance of the device. In summary, this scheme is to make the device into a device supported on the ground.

[0043] like Figure 8It is a second thrust component: a guide groove 43 is opened on the upper surface of the main frame 4, and the thrust component refers to a force-bearing push block 8 installed on the upper surface of the U-shaped platform 13. The U-shaped platform 13 can be pushed by directly pushing the force-bearing push block 8. A handle 9 is set in front of the two fixed rods 21. The U-shaped platform 13 can be moved by holding the handle 9 with one hand and pushing the force-bearing push block 8 with the other hand. Preferably, a spring 14 is assembled between the end of the guide groove 43 close to the corner and the U-shaped platform 13, so that the U-shaped platform 13 can be better reset after losing the thrust. In this embodiment, the device is made into a handheld device, which is more convenient to operate and can also reduce the size of the overall device as a whole, making it more convenient to carry.

[0044] When in use (working), in the initial state, the tension spring 11 is in a natural state. At this time, the angle between the two rectangular frame structures is small. At this time, the flat steel 41 is placed at the corner position, and the length of the side limit frame 2 is adjusted so that the single slide bar 23 fits on the wall. At this time, the flat steel 41, the main frame 4 and the main block 10 are all located on the midline of the corner angle, forming Figure 6 At this time, the U-shaped platform 13 is pushed by the thrust assembly to move, so that the U-shaped platform 13 can gradually approach the corner, at this time, the two laminating plates 31 are away from the angle of the end of the first contact with the wall to form Fig. 9 and then continue to push the U-shaped stage 13, in this process the wall surface applies pressure to the bonding plate 31, so that the angle between the two bonding plates 31 is gradually reduced, at this time the angle between the two detection plates 33 is also gradually reduced, forming Fig.10 The state shown; until the formation Fig.11 In the state shown, the included angle of the bonding plate 31 represents the included angle of the wall corner, and the included angle of the two detection plates 33 can be read by the protractor 12 , that is, the included angle of the bonding plate 31 .

[0045] Embodiment 2: Combination Figure 13-Figure 22 As shown, the difference between this embodiment and the first embodiment is that the bonding plate 31 is bonded to the wall in a different manner. Specifically, a movable seat 6 is provided on the side of the U-shaped platform 13 away from the corner of the wall, a spring 7 is installed between the movable seat 6 and the U-shaped platform 13, and an inclined push rod 63 is provided on the movable seat 6; the angle formed by the two detection plates 33 is initially an acute angle (such as Fig.13 and Fig.14 as shown).

[0046] Preferably, a slider 61 is provided on both sides of the movable seat 6, and the slider 61 can also slide on the guide rail 42, and in this embodiment, when the first thrust assembly is adopted, the nut 53 is fixedly connected to the movable seat 6, and when the second thrust assembly is adopted, the force-bearing thrust block 8 is fixed on the movable seat 6.

[0047] The thrust assembly is used to push the movable seat 6 close to the U-shaped platform 13. When the movable seat 6 is pushed, it can slightly compress the spring 7, and then push the U-shaped platform 13 close to the corner through the spring 7. After the U-shaped platform 13 is in place, the spring 7 continues to be compressed, and the push rod 63 pushes the rectangular frame structure to open.

[0048] Preferably, C-shaped steel 132 is provided on both sides of the U-shaped carrier 13, C-shaped steel 1 62 is provided on both sides of the movable seat 6, and spring 1 7 is assembled between C-shaped steel 132 and C-shaped steel 1 62.

[0049] The rectangular frame structure also includes a telescopic rod 38, which includes an outer tube 382 fixed on the detection plate 33, an inner rod 381 with one end fixed on the bonding plate 31 and the other end inserted into the outer tube 382, ​​and a connecting rod 383 for connecting each inner rod 381. A spring three 384 is fixed on one end of the inner rod 381 inserted into the outer tube 382, ​​which can be squeezed when the bonding plate 31 is subjected to pressure from the wall, so that the bonding plate 31 pushes the inner rod 381, and the inner rod 381 compresses the spring three 384 to shorten the length of the inner rod 381 and the outer tube 382 to adapt to the pressure from the wall. The connecting rod 383 here is used to maintain the parallel state of each inner rod 381, thereby indirectly maintaining the parallel state of the bonding plate 31 and the detection plate 33.

[0050] Preferably, a clearance groove 133 is provided on the side wall of the U-shaped carrier 13 in an area opposite to the detection plate 33 , and the clearance groove 133 is used to avoid the detection plate 33 .

[0051] When in use (working), in the initial state, the angle between the two rectangular frame structures is small, such as Fig.14 The thrust assembly pushes the movable seat 6 to move the movable seat 6 close to the U-shaped platform 13. When the movable seat 6 is pushed, it can slightly compress the spring 17, and then the spring 17 pushes the U-shaped platform 13 close to the corner until the end of the bonding plate 31 close to the corner reaches the wall surface, which can form Fig. 20 Then, the movable seat 6 is continuously pushed, the movable seat 6 compresses the spring 7, and gradually pushes the detection plate 33 through the push rod 63, so that the detection plate 33 is opened. At the same time, the bonding plate 31 can be squeezed when subjected to the pressure of the wall, so that the bonding plate 31 pushes the inner rod 381, and the inner rod 381 compresses the spring 384, so that the length of the inner rod 381 and the outer cylinder 382 is shortened to adapt to the position change caused by the rotation of the rectangular frame structure caused by the pressure of the wall, forming Fig.21 In the state shown in FIG. 1 , as the moving seat 6 is continuously pushed, the angle of the rectangular frame structure is continuously changed, and the U-shaped carrier 13 also moves forward slightly (this is to compensate for the position change caused by the rotation of the rectangular frame structure). Finally, the position of the U-shaped carrier 13 and the angle of the rectangular frame structure are self-consistent, forming Fig. 22In the in-place state shown, the angle data can be read by the protractor 12 at this time.
