[0025] The utility model provides a deflection measuring device for cantilever steel. Figure 1-Figure 3 As shown, the deflection measuring device of the cantilever steel comprises:

[0026] A base 2 and a laser source 3, wherein the base 2 is arranged on a horizontal plane of the cantilevered steel 1, and the laser source 3 is placed on the base 2, and the laser source 3 emits an incident light 4 from one end of the cantilevered steel 1 to the other end;

[0027] A reflection component, wherein the reflection component is tiltedly arranged at one end of the cantilevered steel 1 away from the laser source 3, and the incident light 4 is reflected on the surface of the reflection component to generate a reflected light 8;

[0028] A scale 9, wherein the scale 9 is arranged perpendicular to the cantilever steel 1, and the reflected light 8 reaches the surface of the scale 9;

[0029] In this embodiment, the reflective component includes a steel plate short column 5, a mirror support 6 and a mirror 7. The steel plate short column 5 is arranged obliquely on the cantilever steel 1, and the mirror 7 is arranged on the mirror support 6. The steel plate short column 5 provides support for the mirror support 6. When a load is placed on the cantilever steel 1, deflection will occur between the reflective component and the cantilever steel 1, and the incident angles and the emission angles of the incident light 4 and the reflected light 8 will change. Finally, the position where the reflected light 8 falls on the scale 9 will change. The change data here is the deflection data of the cantilever steel.

[0030] The cantilever steel 1 is fixed to the floor slab by an anchor ring, and the base 2 is a lifting platform structure that can be adjusted in the prior art, including but not limited to a mechanical lifting platform and an electric lifting platform. The purpose of using the lifting platform is to ensure that the incident light 4 of the laser source 3 is irradiated onto the mirror 7 at a suitable height; the deformation of the cantilever steel 1 will change the angle between the reflection plane of the mirror 7 and the incident light 4, and finally change the landing point of the reflected light 8; the whole set of structural principles is simple, and the base 2, the laser source 3 and the scale 9 are all movable structures, which can be temporarily arranged according to the needs of the construction site. The whole set of test equipment is simple in principle and easy to arrange, and the equipment testing work can be completed quickly;

[0031] As a preferred implementation in this embodiment, a disc is provided at the bottom of the steel plate short column 5, and the disc is fixedly connected to the cantilever steel 1 by screws;

[0032] In this embodiment, the steel plate short column 5 itself is arranged at an angle to the cantilever steel 1, mainly to provide a reflection support platform for the reflection of the laser, to help the incident light 4 change direction and reflect outward, and the inclination angle of the steel plate short column 5 itself is preset. In order to adapt to cantilever steels 1 of different lengths, the steel plate short column 5 can be preset with different inclination angles, for example, the angle between the steel plate short column 5 and the horizontal plane is between 70° and 85°; the purpose of using different angles is to match the steel plate short column 5 with a larger angle according to the length of the cantilever steel 1, so that the light can be irradiated on the ruler 9 under the effect of reflection, so as to avoid exceeding the measuring range of the ruler 9;

[0033] As a preferred implementation in this embodiment, a mirror support 10 is provided on the mirror support 6; the mirror support 10 includes an outer layer structure 11 and an inner layer structure 12, the outer layer structure 11 and the inner layer structure 12 are composed of rectangular frames with different inner diameters, the outer layer structure 11 and the inner layer structure 12 form a stepped structure at the inner edge to support the mirror 7, the outer edge of the mirror 7 is abutted against the inner edge of the outer layer structure 11, and the side of the mirror 7 away from the reflecting surface is abutted against the inner layer structure 12, the outer layer structure 11 is provided with a slot on the side close to the cantilever steel 1, and the mirror 7 is arranged parallel to the steel plate short column 5 after being inserted into the slot;

[0034] In this embodiment, the mirror surface 7 adopts a reflector in the prior art, and the structure of the mirror surface 7 is adapted to the mirror holder 10, and the mirror holder 10 is a square or rectangular structure; the mirror surface 7 is also placed in a movable chain connection manner, which can effectively improve the flexibility of the device, and can be effectively and quickly disassembled during on-site assembly, which is convenient for carrying;

[0035] As a preferred implementation in this embodiment, the scale 9 is provided with scale values;

[0036] In a further preferred embodiment of the utility model, the ruler 9 can directly adopt the measuring ruler of the prior art. In the field of construction measurement, this device has many usage scenarios and can be directly used in mature on-site equipment;

[0037] This application works as follows:

[0038] The cantilever steel 1 is fixed to the floor slab by an anchor ring, a steel plate short column 5 is fixed to the cantilever end of the cantilever steel 1, a mirror support 6 is welded to the steel plate short column 5, and a mirror 7 is fixed by snapping into a mirror holder 10 connected to the mirror support 6. On the anchor end steel beam of the cantilever steel 1, the height of the base 2 is adjusted and the height of the laser source 3 is adjusted so that the emitted light 4 emitted by it can be irradiated on the mirror 7. The mirror 7 and the emitted light 4 are at a certain inclination angle, that is, the incident angle B and the reflection angle A are not equal to 0° and are less than 90°. The reflected light 8 generated by the mirror 7 returns to the scale 9 set on the anchor end steel beam of the cantilever steel 1. Finally, the scale reading on the scale 9 is read. The difference in the reading is the height difference change of the reflected light 8 measured twice before and after, thereby the front and rear deflection change value of the cantilever steel 1 can be calculated.
