Description

Technical Field

[0001] The present invention relates to building measurement, and specifically to a device for measuring the inclination angle and direction of columns. Background Art

[0002] The protection of historical and cultural heritage is imperative and the intensity is increasing continuously. Generally speaking, ancient Chinese buildings are mainly made of wood structures, supplemented by bricks, tiles and stones. Wooden columns are important load-bearing structures, usually combined with horizontal wooden structure components such as beams, purlins and lintels to form a roof truss. However, after a long time, due to natural factors such as wind, humidity, insect infestation, or factors such as uneven and unstable foundations, the column foundations of columns often have different degrees of settlement and inclination, bringing potential safety hazards to the building. At this time, it is necessary to measure the inclination angle and direction of the inclined columns to provide data support for the subsequent correction and repair of the columns in advance.

[0003] From the perspective of existing technologies, the measurement is divided into two technical methods: traditional and new. For traditional measurement technologies, a combination of a square, a steel ruler and a plumb bob is used for measurement. Although this technology can quickly measure the inclination angle of the column and the measurement cost is very low, it cannot accurately measure the subtle inclination angle and direction, and has great limitations. For new measurement technologies, 3D scanning technology is used, combined with professional analysis software, which can accurately measure and calculate the subtle inclination angle and direction of the column. Although this technology can analyze the subtle inclination angle and direction of the column with the highest precision, the corresponding machines and software require high costs and the measurement process is complex, resulting in a very high measurement cost. Also, because it is a professional electronic analysis, a large amount of measurement data is required, which increases the measurement cycle and leads to an increase in the construction cycle. This technology obtains a relatively accurate conclusion at the cost of increasing measurement cost and time, and also has certain limitations. Summary of the Invention

[0004] Object of the Invention: The object of the present invention is to provide a device for measuring the inclination angle and direction of columns that can be fast, accurate, simple to operate and low-cost.

[0005] Technical Solution: A device for measuring the inclination angle and direction of columns according to the present invention includes a plurality of arc-shaped measurement patches wrapped around the circumferential surface of the column, a fixing strap for fixing the measurement patches, and a measurement platform; the measurement platform is arranged at the top of the measurement patches, and a gravity sensing member for displaying the inclination direction of the column is arranged inside the measurement platform, and an angle detection member for measuring the inclination angle is connected to the bottom, and a window for observing the internal gravity sensing member is arranged on the measurement platform.

[0006] Further, the gravity sensing member is a bubble level or a ball.

[0007] Further, the measurement platform and the angle detection member are connected by a magnetic attraction method.

[0008] Further, a plurality of concave mortise openings with built-in magnets are arranged at intervals at the bottom of the measurement platform. The top end of the angle detection member is a convex tenon plug-in member embedded with a magnet. The concave mortise opening and the convex tenon plug-in member can be matched and inserted and adsorbed. The setting of the concave-convex mortise and tenon structure and the magnet can enhance the connection strength between the measurement platform and the angle detection member.

[0009] Further, the bottom end of the angle detection member is coated with a pointer shape and coincides with the 0° scale line on the fan-shaped protractor hinged to the bottom end in the initial state.

[0010] Further, the fixing strap is a Velcro strap.

[0011] Further, the top ends of the measurement platform and the measurement patch are tightly connected by a magnetic attraction method, and magnets for adsorbing to the measurement patch are arranged inside the bottom of the measurement platform.

[0012] Further, magnets for tightly connecting adjacent measurement patches are arranged at both ends of the top of the measurement platform.

[0013] Further, the top or side of the measurement platform is made of high-transparency glass; the inclination direction of the column can be directly and clearly perceived by observing the position state of the internal gravity sensing member.

[0014] Principle of the present invention: The present invention is closely attached to the column to be measured. When the gravity sensing member in the device is affected by gravity, the position state is quickly amplified to reflect the inclination direction of the building column, and the judgment can be made intuitively and accurately; then, the rotation of the hinged protractor in the device is matched with the pointer of the inclination measurement member to directly display the inclination angle; the inclination angle and direction of the column can be quickly and accurately measured by the device of the present invention.

[0025] As Figure 1 shown, when using the present invention to measure the columns of a building, the fixing strap 2 is passed through the strap positioning holes 4 on the outer sides of several arc-shaped measurement patches 1, so that the measurement patches 1 are evenly and tightly attached to the circumferential surface of the column to be measured, and it is ensured that the center of the cylinder formed by the measurement patches is on the same straight line as the column to be measured; preferably, the fixing strap 2 is a magic tape, and its self-adhesive property is used to facilitate the tightening and disassembly of the measurement patch 1. The measurement platform 3 is tightly adsorbed on the top end of the measurement patch 1. Specifically, the magnet 10 provided on the inner side of the bottom of the measurement platform 3 and the small magnet embedded in the top end of the measurement patch 1 are attracted to each other for tight connection. Preferably, magnets 11 for tightly connecting adjacent measurement patches 1 are provided at both ends of the top of the measurement platform 3, which is convenient for forming a ring-shaped measurement platform 3 that fits the measurement patch 1. The inclination direction and angle of the building column are observed and data is read by the gravity sensing member 5 provided inside the measurement platform 3 and the angle detection member 6 connected to the bottom. The measurement platform 3 is provided with a window through which the position of the gravity sensing member 5 inside can be directly observed. Preferably, the window is set to be made of a transparent material at the top or side of the measurement platform 3. Specifically, the transparent material is high-transparency glass. The gravity sensing member 5 is several balls or bubble levels. When the column to be detected is inclined, under the action of gravity, the balls will gather towards the inclined side. If a bubble level is used, the bubble will be squeezed to the opposite direction of the inclination, so that the state of the gravity sensing member 5 inside the measurement platform 3 can be directly observed to show the inclination direction. As Figure 2 shown, specifically, the top of the measurement platform 3 is made of glass, and the gravity sensing member 5 is several colored glass balls. When the column to be detected is inclined, the glass balls will gather towards the inclined direction. As Figures 3 to 6As shown, the measurement platform 3 and the angle detection member 6 are connected by magnetic attraction. Specifically, a number of concave mortise openings 7 with built-in magnets are arranged at intervals at the bottom of the measurement platform 3. The top end of the angle detection member 6 is a convex tenon plug-in 8 embedded with a magnet. The concave mortise opening 7 and the convex tenon plug-in 8 can be matched and inserted and adsorbed to each other. As Figure 5 shown, the bottom end of the angle detection member 6 is coated with a pointer-shaped sector protractor 9 that coincides with the 0° scale line on the protractor and is hinged to the bottom end in the initial state. When the column is tilted, the bottom end pointer of the angle detection member 6 is on the same straight line as the tilted column, while the sector protractor 9 hinged at the bottom remains perpendicular to the ground. At this time, the included angle formed by the pointer and the scale line on the sector protractor 9 is the tilt angle of the column. In this way, the tilt angle and direction of the building column can be quickly and accurately measured.
