Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering measurement, in particular to multifunctional measurement equipment for construction engineering. Background Art

[0002] Construction projects refer to the general term for various types of buildings and engineering facilities that provide the material and technical basis for human life and production. Construction projects are organized, purposeful, large-scale economic activities of human beings. According to their natural attributes, they can be divided into three categories: construction projects, civil engineering projects, and mechanical and electrical engineering projects. They are engineering projects that form comprehensive production capacity or exert engineering benefits in the process of fixed asset reproduction. During the construction of construction projects, it is necessary to measure the size and inclination of the building. At present, when measuring the building, the operator is required to use different measuring tools to measure the size and angle respectively, which not only increases the physical labor of the operator, but also reduces the measurement efficiency.

[0003] In this regard, Chinese patent publication number CN211476898U discloses a multifunctional measuring device for construction projects, including a first shell, a second shell is arranged in the first shell, and an angle measuring device is arranged in the second shell; by setting the first shell and the second shell, the measuring length of the device can be changed as needed, and when measuring objects with longer lengths, the number of measurements is reduced, and when measuring shorter objects, the measurement area can be reduced, thereby improving the applicability of the device. At the same time, an angle measuring device is arranged in the second shell, which can measure the angle of the measured object, has a multi-purpose function, and brings convenience to construction measurement.

[0004] The above technology discloses a multifunctional measuring device for construction projects, which can be combined and rotated to unfold by a first shell and a second shell, and can measure the length in conjunction with the scale line on the front side thereof, and can measure the angle between adjacent objects in conjunction with the expandable arc cloth arranged inside. However, it still has the following shortcomings: 1. The length can be measured only by rotating and unfolding the first shell and the second shell. Due to the limited total length of the two, it is difficult to accurately and quickly measure the length of buildings that are far apart, and the measurement accuracy is not ideal; 2. The inclination of a wall or foundation cannot be measured alone, and the method of only measuring the angle is not flexible; improvement is needed. In view of this, we propose a multifunctional measuring device for construction projects to solve the above problems. Utility Model Content
