On construction sites, we often see workers using line hammers to draw lines. The line hammer is the most primitive tool for verifying the verticality of objects, and it is also one of the tools currently used to test the verticality of objects. But not all people will use and understand, then how much is the line hammer? How to use the line hammer to suspend the line before accurate?

How to use the line hammer to suspend the line before accurate?
With heavier special pendant suspensions, it is necessary to determine the intersection point of the axis, and the survey axis shall be suspended directly to each construction layer.
(1) The geometric shape of the wire should be normalized and the weight should be appropriate (1~3kg). Hanging wire with braided and untwisted fine wire.
(2) When the suspension is suspended, the upper end should be fixed firmly and there should be no obstacle in the middle of the line, especially if there is no lateral resistance.
(3) The lower end of the line (or tip of the line) should have a vertical structural plane when the line of sight is viewed. When the left line and right line are less than 3 to 4 mm, take the average position. The difference between the two average positions is less than 2 At 3mm, take the average position again as a result of the test.
(4) During the test, wind and vibration should be prevented, especially the lateral wind.
(5) In the layer-by-layer test, use a larger wire drop (for example, 5kg) every 3 to 5 layers, and put a direct line up from below to make a test.
How much is a line hammer? How to use the line hammer to suspend the line before accurate? After reading the above introduction of the small series, it must be clear that everyone should have a clear understanding of how to use the line hammer. The line hammer is a tool that construction workers often use and plays an integral part in the construction of the project. effect.
