Description
Technical field
The invention belongs to science of bridge building technical field of measuring equipment, it particularly relates to thick to a kind of bridge box and beam section
Spend measuring instrument.
Background technology
With the development of highway Large scale construction, bridge quantity rapidly increases, and the security performance of bridge is increasingly by people
Paid attention to.Due to the use of the effect of load, environmental factor and structure defect etc. itself so that bridge it is safe to use by not
With the influence of degree.Therefore it needs to detect the specific quality of bridge and security performance through row, but the prior art is to being completed bridge
Box section thickness can not directly measure.For example, Chinese patent (CN201289359Y) although disclosing a kind of measuring scale, is somebody's turn to do
Measuring scale is connected to the upright bar perpendicular to the right angle chassis plane on right angle chassis, and rabbeting on the lateral surface of upright bar has sliding ruler
Plate, but it is only used for the measurement of thickness of box girder formwork tinertoy web, and cannot directly measure box section thickness.
Invention content
In order to solve the above technical problems, the present invention provides a kind of bridge box and beam section thickness measurements that can directly measure
Instrument.
A kind of bridge box and beam section thickness measuring instrument of the present invention, the measuring instrument include ruler 1, rounded corner ruler 2, base
Ruler 3, fixture block 4, brake head 5, control knob 6, transmission rope 7, the shaft 8 with spring, movable claw 9；1 one end of the ruler is equipped with control
Button 6, the other end are connected with movable claw 9 by the shaft 8 with spring；The fixture block 4 is slidably disposed on ruler 1, thereon
It is connected to brake head 5；There are two the base ruler 3 is total, one end is all connected with brake head 5, and the other end is separately connected 2 both sides of rounded corner ruler
Bottom edge；There are two the movable claw 9 is total, control knob 6 is connected to by transmission rope 7.
A kind of bridge box and beam section thickness measuring instrument of the present invention, the base ruler 3 point-blank and with circle
Angle square 2 is rigid connection.
A kind of bridge box and beam section thickness measuring instrument of the present invention, the base ruler 3 can be dynamic for shaft rotation with brake head 5,
And rounded corner ruler 2 is driven to be rotated about centered on brake head 5.
A kind of bridge box and beam section thickness measuring instrument of the present invention, the movable claw 9 are tightly attached to 1 both sides of ruler,
Leading inside is installed with transmission rope 7 respectively.
A kind of bridge box and beam section thickness measuring instrument of the present invention, the control knob 6 can rotate and affect transmission rope
7, to drive two movable claws 9 around 8 opposite direction rotating of shaft with spring.
A kind of bridge box and beam section thickness measuring instrument of the present invention, cutting of the transmission rope 7 on 1 blade of ruler
It is connected to control knob 6.
A kind of bridge box and beam section thickness measuring instrument of the present invention, the preparation method of the transmission rope 7 are：Take sisal hemp
Yarn twisting forms five sisal hemp rope strands, is fixed at center with one external by four, forms cable core；Steel wire is taken to twist
Ten compression rope strands are formed, these compression rope strands are twisted together around cable core later, obtain transmission rope 7.
A kind of bridge box and beam section thickness measuring instrument of the present invention, the sisal hemp yarn percent mass are a concentration of
The alcohol solution dipping of 2% little Hua gold earpick element crosses 2-5h.
In use, according to drawing and practical selected region, measuring point quantity and the position to be measured of incorporation engineering；Use electric drill
It drills in selected box girder web position, drill bit is more bigger than ruler size, and web is got through, while ensureing that drilling is substantially suitable
Directly；Electric drill is removed, the fixture block of box beam thickness measurement equipment ruler is moved on to suitable position, so as on ruler by the interior dirt slag of cleaning drilling
Movable claw be fully inserted into hole, and take-off the brake head, rotation base ruler keeps base ruler and ruler substantially vertical；Ruler is stretched along drilling
Enter web, (web thickness that can refer to design drawing suitably puts in ruler more until the movable claw of ruler passes completely through web
A bit), rotation control is turned round, and so that two movable claws is opened completely, two pawl points withstand ruler ruler head；It is slowly displaced outwardly ruler, directly
It is close to two movable claw pawl bodies with inside measuring surface, while mobile fixture block, so that fixture block is touched hole wall, then rotate rounded corner ruler,
The side group ruler for keeping reading larger is close to measuring surface, and rotation brake head makes rounded corner ruler and ruler be kept fixed；It is right to read fixture block
The scale of side ruler, and record reading；Again using ruler top as reading index line, the scale of rounded corner ruler is read, and is recorded
Reading；Take-off the brake head rotates base ruler, keeps base ruler and ruler substantially vertical；Then fixture block is moved, makes fixture block far from tested surface；
Ruler a distance is moved inward so that movable claw is withdrawn, then rotating control knob makes two movable claws withdraw, and is respectively close to
Ruler is slowly removed and is drilled, then resets rounded corner ruler by the both sides of ruler, and the braking of rotation brake head is measured；It will measure
Length and angle can be obtained box section thickness by simple computation, when measurement ruler can drill at one in wheel measuring
Repeatedly, every group of measured value takes mean value after calculating separately so that measured value is more accurate.
Compared with prior art, a kind of bridge box and beam section thickness measuring instrument of the present invention.Except can accurately measure bridge
Outside spar-box beam section thickness, also have the characteristics that using simple, the various angles of inclination of adaptation, reading is intuitive, processing cost is low.
