Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1-7, a straightness measuring instrument hangs down, includes main measuring part and enlarger part, main measuring part includes mobile jib 4 and scale one 8, and scale one 8 transversely is fixed in mobile jib 4 bottom, 0 scale mark of scale one 8 and the coincidence of the central line of mobile jib 4, and mobile jib 4 in this embodiment is the wooden body of rod, be fixed with balancing unit on the mobile jib 4, balancing unit includes metal pole 5 and balancing pole 7, metal pole 5 is articulated through rivet 1 and mobile jib 4 top, balancing pole 7 middle part transversely is fixed in metal pole 5 bottom, in this embodiment, metal pole 5 and balancing pole 7 are the aluminium material and make the body of rod.
In order to optimize the product structure and improve the verticality and stability of the measuring tool during measurement, the balance bar 7 is fixed with balance balls 6 at both ends, and in this embodiment, the balance balls 6 are solid spheres made of stainless steel materials, and have uniform texture and consistent weight.
The enlargement portion includes two scales 10, two 10 longitudinal fixings of scale are in the 4 bottoms of mobile jib, be provided with perpendicular line 9 on two scales 10, in this embodiment, perpendicular line 9 is made for the fish tape, 9 tops of perpendicular line are fixed in 8 middle parts of scale, and 9 ends of perpendicular line are fixed with circular band iron 12, in this embodiment, 12 cross-sections of circular band iron are circular, and its diameter is 4mm, and thickness is 2 mm.
In order to further improve the stability of the measuring tool during measurement, fixing devices are arranged on the top of the main rod 4 and the bottom of the second scale 10, each fixing device comprises a screw rod 2 and a nut 3, the screw rods 2 penetrate through the top of the main rod 4 or the bottom of the second scale 10 and are in threaded connection with the main rod, the screw rods 2 are perpendicular to the main rod 4 and the second scale 10, and the nuts 3 are connected to two ends of each screw rod 2; in this embodiment, screw 2 is M14 screw 2.
In order to facilitate direct reading of the offset distance of the template during measurement, a third scale 11 is fixed at the bottom of the second scale 10.
According to GB50204-2015 'specification of concrete structure engineering quality acceptance' 4.2.10, for the cast-in-place column wall formwork, when the layer height is less than or equal to 6m, the allowable deviation of the installation size is 8mm, and when the layer height is greater than 6m, the allowable deviation of the installation size is 10 mm. Therefore, the overall height of the measuring tool in the embodiment is 3m, and the lengths of the main rod 4 and the second scale 10 are equal to each other and are both 1.5 m; the metal rod 5 and the balance mount are square aluminum alloy rod pieces with 5mm multiplied by 5mm interface.
