Abstract
The utility model discloses a kind of levelling rod convenient for foundation trench level measurement and helps ruler device, including card slot, spirit level and handrail；The card slot is half frame-shaped construction, its both ends is equipped with the adjustable apparatus of clamping measurement foundation trench absolute altitude levelling rod, the distal end of handrail is fixed at the back side of the card slot along the length direction of handrail, and the spirit level is fixed on along handrail length direction close to handrail proximal point.The utility model can fast and effeciently read the scale numerical value of levelling rod by spirit level.
Description
Technical field
The utility model relates to foundation trench measuring tools, and in particular to a kind of levelling rod convenient for foundation trench level measurement helps ruler to fill
It sets.
Background technique
It in building construction process, when foundation trench excavates, needs to carry out absolute altitude control with level, when vertical levelling rod often
It needs to slot bottom under personnel, when encountering bad nature of soil or ponding foundation trench, slot bottom measurement work is more difficult, needs temporarily to repair just
Road just can be carried out the measurement of absolute altitude, cumbersome and time consuming.
Summary of the invention
Goal of the invention: the utility model aim is in view of the deficiencies of the prior art, to provide a kind of convenient for the survey of foundation trench absolute altitude
The levelling rod of amount helps ruler device.
Technical solution: a kind of levelling rod convenient for foundation trench level measurement described in the utility model helps ruler device, including card slot,
Spirit level and handrail；The card slot is half frame-shaped construction, and both ends are equipped with the adjustable dress of clamping measurement foundation trench absolute altitude levelling rod
It sets, the distal end of handrail is fixed at the back side of the card slot along the length direction of handrail, and the spirit level is solid along handrail length direction
Due to close to handrail proximal point.
Preferably, the adjustable apparatus is that correspondence offers screw hole on half frame-shaped construction both ends, is equipped in the screw hole
Adjusting screw, by adjusting, the adjusting screw is vertical with levelling rod to be gripped the card slot.
Preferably, the card slot is fixed on handrail by fastening bolt.
The utility model has the advantages that (1) the utility model is by being set to the vertical spirit level of levelling rod, and the level for passing through spirit level
Bubble judges the vertical vertical of levelling rod between two parties, can read correct reference mark numerical value, and the utility model assembling is simple
Fast, it can repeatedly use, can be improved accuracy when foundation trench level measurement, reduce the deviation of foundation trench absolute altitude numerical value；
(2) clip slot of the utility model is connect by adjustable apparatus with levelling rod, and the utility model is according to the depth of foundation trench
It spends to adjust the height and position for helping ruler device on levelling rod, can be applied to the level measurement of a variety of foundation trenches, improve work
Make efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that levelling rod described in the utility model helps ruler device；
Fig. 2 is the bottom view that levelling rod described in the utility model helps ruler device；
Fig. 3 is the application drawing of the utility model in embodiment.
Wherein, 1- adjusting screw；2- card slot；3- fastening bolt；4- handrail；5- spirit level；6- levelling rod；7- foundation trench.
Specific embodiment
Technical solutions of the utility model are described in detail below by attached drawing, but the protection scope of the utility model
It is not limited to the embodiment.
Embodiment: a kind of levelling rod convenient for foundation trench level measurement helps ruler device, including card slot 2, spirit level 5 and handrail 4；
Card slot 2 is half frame-shaped construction, and both ends are equipped with the adjustable apparatus of clamping measurement foundation trench absolute altitude levelling rod 6, and card slot 2 uses 3mm
Thick steel plate cuts welding production, and is customized according to 6 sectional dimension of levelling rod, and sky is having a size of 6 width+2*(tune of levelling rod in card slot 2
Save screw silk head length-steel plate thickness), handrail 4 is fixed on by fastening bolt 3 along the length direction of handrail 4 in the back side of card slot 2
Distal end, spirit level 5 is fixed on along 4 length direction of handrail close to 4 proximal point of handrail, and handrail 4 is using using 4cm × 4cm
The wooden a tree, used in making timber for boats completes；Spirit level 5 is located on horizontal plane, and vertical with levelling rod 6；Adjustable apparatus is on half frame-shaped construction both ends
It is corresponding to offer screw hole, adjusting screw 1 is equipped in screw hole, card slot 2 is solid by adjusting the clamping vertical with levelling rod 6 of adjusting screw 1
It is fixed.
Levelling rod 6 is placed in foundation trench 7 in the present embodiment, and card slot 2 is held on to the top of levelling rod 6, and makes to help
The proximal end of bar 4 is to be equipped with above the rim surface of one end stretching foundation trench 7 of spirit level, adjusts the verticality of levelling rod 6, makes water
The level(l)ing bubble of quasi- device 5 is placed in the middle, and then measures the absolute altitude numerical value of foundation trench 7, to show that the absolute altitude of levelling rod 6 is precisely read.
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not
It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define
Under the premise of, it can various changes can be made in the form and details to it.
