Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a wall verticality measuring device for building construction. Background Art
[0002] Construction refers to the production activities during the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. Construction is a production activity in which people use various building materials and mechanical equipment to build various construction products in a certain space and time according to a specific design blueprint. It requires the use of some surveying and mapping instruments to assist in construction.
[0003] As in the prior art, the Chinese utility model with publication number: CN217032516U discloses a wall verticality measuring device for construction, including a base plate, an adjusting cylinder is arranged on the top of the base plate, a second motor is arranged on the top of the adjusting cylinder, a threaded rod is arranged at the output end of the second motor, an adjusting mechanism is arranged outside the threaded rod, a sliding notch is provided on one side of the adjusting cylinder, and an entry piece is provided at the bottom of the base plate. The threaded rod is driven to rotate by the second motor, so that the position height of the adjusting mechanism is conveniently adjusted according to the internal thread that is matched with the external thread of the threaded rod provided inside the threaded hole, which can effectively improve the efficiency and accuracy of the measurement, and the winding roller is driven to rotate by the first motor, so that the length of the traction rope is increased according to the position height of the adjusting mechanism, which is suitable for wall column formworks with different heights, avoids manual climbing scaffolding measurement, and improves the safety of the measurement personnel.
[0004] In the above technical solution, the base plate is fixed by embedded parts. First, there is no reference standard for the verticality of the device. At the same time, after the device is installed, it is impossible to know how to measure the verticality of the wall. Then, an angle ruler is installed on the fixed plate. The angle ruler is distributed in an arc shape, and the angle ruler uses the center of the circle of the angle ruler as the standard point when measuring the angle. In the above technical solution, as the adjustment mechanism rises, the traction rope swings with the limit hole as the center of the circle. The position of the center of the circle does not coincide with the center of the angle ruler. The angle ruler cannot measure the angle of the traction rope deviation, which can easily lead to the above measurement structure not matching the actual inclination angle of the wall.
