Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that in the actual use of the prior art, the distance of visual observation is affected by various accidental errors due to the changeable construction environment, the accuracy of manual measurement is poor, and the change of cracks cannot be reflected objectively. There are problems that cannot be widely deployed and intuitive and convenient reading, and a kind of building (structure) crack monitoring device and its use method are proposed

Embodiment 1

[0033] Embodiment one, with reference to Figure 1-3 , a crack monitoring device for buildings (structures), comprising an upper cover plate 1 and a lower backing plate 2, the bottom side of the upper cover plate 1 is slidably connected with the upper side of the lower backing plate 2 through a sliding assembly, the upper cover plate 1 and the lower backing plate 2 The lower backing plate 2 is provided with a visual scale monitoring component, and the upper end of the lower backing plate 2 is provided with a laser displacement sensor 3 corresponding to the end of the upper cover plate 1 .

[0034] The upper cover plate 1 and the lower backing plate 2 can be respectively fixed on both sides of the crack, and the upper cover plate 1 and the lower backing plate 2 can be combined through the sliding assembly. Relative sliding produces displacement, and the change scale of the crack can be directly read through the visual scale monitoring component. The laser displacement sensor 3 ...

Embodiment 2

[0038] Embodiment two, refer to Figure 1-3 , a device for monitoring cracks in buildings (structures), the structure of this embodiment is roughly the same as that of Embodiment 1, the difference is that:

[0039] It also includes the lower fixing holes 6 and the upper fixing holes 10, the thicker end of the lower backing plate 2 is provided with the lower fixing holes 6, and the thinner end of the upper cover plate 1 is provided with the upper fixing holes 10. The lower backing plate 2 and the upper cover plate 1 can be respectively fixed through the fixing holes 6 at the lower end and the fixing holes 10 at the upper end.

Embodiment 3

[0040] Embodiment three, refer to figure 1 , a building (structure) crack monitoring device, the present embodiment is a further description of embodiment two:

[0041] The sliding assembly includes a sliding convex groove 9 and a sliding groove 7. The bottom of the thinner end of the upper cover plate 1 is provided with a horizontal sliding convex groove 9. There are two sliding convex grooves 9 and they are arranged on the upper cover plate 1. The front and rear sides of the bottom of the thinner end, and the top of the thinner end of the lower backing plate 2 are provided with a sliding groove 7 that is slidably connected with the sliding convex groove 9 . This sliding connection is simple and reliable.

Abstract

The invention discloses a building (structure) crack monitoring device and a use method, and belongs to the field of building construction. The building (structure) crack monitoring device comprises an upper cover plate and a lower base plate, the bottom side of the upper cover plate is slidably connected with the upper side of the lower base plate through a sliding assembly, and visual scale monitoring assemblies are arranged on the upper cover plate and the lower base plate; and a laser displacement sensor corresponding to the end part of the upper cover plate is arranged at one end of the upper side of the lower base plate. The upper cover plate and the lower base plate can be fixed to the two sides of a crack respectively, the upper cover plate and the lower base plate can be combined through the sliding assembly, the upper cover plate and the lower base plate relatively slide along with the increase of the crack to generate displacement, and the change scale of the crack can be directly read out through the visual scale monitoring assembly. The laser displacement sensor generates laser to the end of the upper cover plate and then emits the laser back so that the change of displacement is monitored in an electronic mode. Arrangement is convenient, reading is convenient, and monitoring is accurate.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device for monitoring cracks in buildings (structures) and a method for using it. Background technique [0002] The excavation of the foundation pit will cause settlement and displacement of the surrounding area, and cracks will appear in the buildings (structures) close to the foundation pit. The unit takes corresponding measures in advance to provide early warning. [0003] In current construction practice, the monitoring of cracks caused by the displacement of surrounding soil in buildings (structures) mostly adopts the method of marking visual observation and measuring distance. This method is affected by various accidental errors due to the changeable construction environment. [0004] During on-site construction, it is easy to ignore the trend of crack development and change. The accuracy of manual measurement is affected by different measurement positions ...
