Abstract

The utility model relates to a testing six-purpose ruler for the quality of civil engineering, which is a common appliance for testing quality in civil engineering. The product is composed of a ruler body which is connected by three rod members through male pins and hinges and is capable of being mutually perpendicular and being folded, and two accessories: a two-purpose plug ruler and a special-shaped line hammer. In engineering quality test, the testing six-purpose ruler can be used for measuring the gradient of vertical and horizontal planes, surface evenness degree and right-angled degree of deviation and visually test whether a member is vertical or not, and can also replace a measuring scale. The product has one object with multifunction, simple structure, and convenient use and carrying, and has larger superiority than the existing civil engineering quality testing appliance.

Description

Testing six-purpose ruler for quality of civil engineering

One, the utility model relates to a kind of architecture engineering detector tool that integrates multiple use.

Two, the function singleness that has of the detector that uses in China's civil engineering now.Can survey the gradient of surface finish and vertical direction as guiding ruler, but the latter adopts the method for suspending weight throw of pointer, the pointer instability, accuracy of reading is low.And for example the bubble level chi can be checked whether level of plane, but can not measure gradient.The needs that have use a few utensil to detect a project simultaneously, portably use very inconvenient.

Three, the purpose of this utility model is to portably use quality examination utensil easily for civil works provides a kind of one-object-many-purposes, simple structure.

Four, the structure of civil works quality examination six usefulness chis is by chi body and two annexes: dual-purpose clearance gauge (Fig. 8) and special-shaped plumb bob (Fig. 9) are formed.

1, the chi body is made up of the ruler 1 and the chi 2 that hangs down.Ruler connects into collapsible shape by the angle steel of two long 20 * 30 * 3mm of one meter with hinge 3.During use ruler is launched into linear, arm-tie 4 is fastened screw rod 5, tightening nuts, two meters long rulers.The standard trolley 6 that it is 20 * 2mm that ruler one end is welded with long 10CM section, the other end have the tee-section plate 7 on the spot of 10 * 4 * 2CM of thick 2mm, and exsertile slotting ground bar 8.

The chi that hangs down is made by 30 * 3mm steel plate of one long one meter, at one end is connected with pin 9 with ruler, and can is fixed into ruler perpendicular by the positioning bolt 10 that is installed on the standard trolley.The time spent can not unclamped positioning bolt, makes the chi half-twist that hangs down, and coincides with ruler.There is the thread gripping-board 24 by rotatable 270 ° of hinge 23 on the ruler top.

In lateral surface 11 total lengths of 2000 * 30mm of ruler wing lattice being arranged is the scale of 1CM, near the 20CM scope of the chi root that hangs down then lattice divide the scale of 0.5CM into, on the spot lattice is arranged is the scale of 0.5CM in the rib outside 12 of plate T shape.

2, the long 10CM of dual-purpose clearance gauge, wide 1CM, an end are sphenoid, an end is a cuboid, makes with hard toothed oak is wooden, the upper and lower surface bag is with sheetmetal, below (flat face 13) lattice is arranged is the scale of 0.5CM, above (1:5 inclined-plane 14) lattice is arranged is the scale of 5.03mm.

3, the special-shaped plumb bob partly is made up of hammer tube, bar pin and messenger wire three.The former two makes with steel material.Hammer tube 15 is the garden tubular, and the screw that threading screw rod 16 is installed, the screw of the mounting rod pin of going to the bottom are arranged in the middle of the upper base.The little garden bar 17 that joint is used for kinking on the bar pin, centre are the screw rod 18 that combines usefulness with the hammer tube, and following joint is a pointer 19.Messenger wire one end has hook 20, and the control ply-yarn drill 21 that can elongate or shorten messenger wire fast is equipped with in the centre.

Five, advantage of the present utility model

1, one-object-many-purposes, this detection ruler can be used for:

The gradient (post, wall etc.) of survey vertical direction (Fig. 1)

The gradient (road surface, ground, wall top etc.) of survey horizontal direction (Fig. 2)

Survey surface finish (road surface, ground, metope etc.) (Fig. 3)

Survey the right angle degree of deviation (as two walls crossing external corner or inner corner trim) (Fig. 4 and Fig. 5)

Visual inspection member whether vertical (template, the stake of preparing to squeeze into etc.) (Fig. 6--1)

The replacement surveyors' staff (Fig. 6--2)

2, above 1,2,3,4 purposes all can be measured than accurate values.Survey vertical and the horizontal tilt degree can be accurate to 1/400 and 1/200; The survey planeness can reach and be accurate to 1mm, surveys the right angle degree of deviation and can be accurate to 1/200 radian.

3, simple structure does not have accurate easily worn part, easily processing and manufacturing.

4, collapsible, portably use conveniently.

Claims

1, chi is used in a kind of civil works quality examination six that integrates six kinds of purposes, it is characterized in that being made up of chi body, dual-purpose clearance gauge and special-shaped plumb bob.

2, use chi according to the civil works quality examination six of claim 1, it is characterized in that to form the folding again chi body in right angle by forming by three straight-bars.

3, use chi according to the civil works quality examination six of claim 1, it is characterized in that standard trolley is arranged on the chi body, on the spot plate, positioning bolt, stretching plate and insert the ground bar.

4, use chi according to the civil works quality examination six of claim 1, it is characterized in that different parts on the chi body has the rule of three different lengths, different lattice, different purposes.

5, use chi according to the civil works quality examination six of claim 1, it is characterized in that having an end is sphenoid, and an end is a cuboid, above (1:5 inclined-plane) and following (flat face) the dual-purpose clearance gauge of the scale of different lattices is arranged.
