Fig. 2 is 21 structural schematic diagram of thin plate loose tool in Fig. 1, please refers to Fig. 1 and Fig. 2.21 bottom of thin plate loose tool is equipped with embedding Rib 211 is closed, thin plate loose tool 21 is fixed on pile formula reinforcement cushion 10 by chimeric rib 211.The corner of thin plate loose tool 21 connects Place's setting corner connection sheet 212 is fixed.It is arranged on thin plate loose tool 21 for fixing outboard template 22 and inner side template 23 Built-in fitting 25 lifts outboard template 22 in actual installation to fixed position.Outboard template 22 and inner side template 23 use unit Formula assembling regularization template.

Referring again to Fig. 1, support frame 32 is located at the left and right sides of construction space, is used to support operation platform 34. Support frame 32 includes supporting beam 321 and sub-truss 322, and supporting beam 321 is located at the bottom of support frame 32, for sub-truss 322 into support.The bottom of supporting beam 321 is connected with universal wheel 31, and sub-truss 322 is erected on supporting beam 321 and operation platform Between 34, sub-truss 322 is connect with outboard template 22.

Operation platform 34 includes platform backing plate 341 and girder truss 342, the bottom and the top of sub-truss 322 of girder truss 342 Portion is connected by adjusting component 40, and the side away from sub-truss 322 of girder truss 342 is connect with platform backing plate 341.In reality It constructs in use, construction personnel stands on operation platform 34.

Adjusting component 40 includes fastener 41 and nut, and operation platform 34 includes the first connector, and support frame 32 includes the Two connectors are connected by fastener 41 with nut between the first connector and the second connector.

Fastener 41 can be bolt, and bolt passes through the first connector and the second connector and nut cooperates.

Fig. 3 is the structural schematic diagram of waist-shaped hole 343 in Fig. 1, please refers to Fig. 1 and Fig. 3.Waist type is provided on first connector Hole 343, waist-shaped hole 343 extend along first direction 80, are provided with connection through-hole corresponding with waist-shaped hole 343 on the second connector, Fastener 41 is arranged in waist-shaped hole 343 and connection through-hole.

Optionally, the inner wall of waist-shaped hole 343 is convexly equipped with blocking part 344, length direction of the blocking part 344 along waist-shaped hole 343 Extend and forms glade plane space 345.

In the present embodiment, blocking part 344 is two and is oppositely arranged.Blocking part 344 is used for when being poured, fastening Part 41 is slided along waist-shaped hole 343.

It is understood that in other embodiments, blocking part 344 can be two be oppositely arranged.

Fig. 4 is the structural schematic diagram of fastener 41 in Fig. 1, and Fig. 5 is A-A cross-sectional view in Fig. 4, please refers to Fig. 4 and Fig. 5.Tightly Firmware 41 includes variant part 410 and interconnecting piece 413.For interconnecting piece 413 for connecting with nut, variant part 410 includes around itself axis The state of glade plane space 345 can be slipped over after heart rotation.

The rank street face of variant part 410 is square structure, and the length dimension of square structure is greater than the broad-ruler of glade plane space 345 Very little, the width dimensions of square structure are less than the width dimensions of glade plane space 345.Square structure includes long side 411 and short side 412.The length dimension of long side 411 is greater than the width dimensions of glade plane space 345, and the length dimension of short side 412 is less than sliding The width dimensions in gap 345.

The practical work process of the cast-in-place box culvert of big cross section is divided into casting process and moving process.Pass through fastener 41 and waist type Hole 343 matches, and realizes the conversion of casting process and moving process with can be convenient.

It in casting process, is relatively moved between fastener 41 and waist-shaped hole 343 in order to prevent, rotates fastener 41 So that the long side 411 of variant part 410 is vertical with first direction 80, at this point, fastener 41 can not be by glade plane space 345, this When blocking part 344 be held in long side 411, limit fastener 41 along the sliding of first direction 80.

After casting complete, when needing along 80 movable supporting frame 32 of first direction, rotation fastener 41 makes variant part 410 short side 412 is vertical with first direction 80, and long side 411 is identical as first direction 80, at this point, fastener 41 can lead to It crosses short side 412 to slide along blocking part 344, passes through glade plane space 345.

Thus, it is only required to by rotation fastener 41, so that the different sides of variant part 410 are against blocking part 344, Ji Keshi The conversion of existing casting process and moving process, improves construction efficiency, accelerates construction speed.

Adjusting component 40 further includes tension part, and fastener 41 offers limiting through hole 414.The axis of limiting through hole 414 with The axis of fastener 41 intersects.Tension part is arranged in limiting through hole 414, and the both ends of tension part and support frame 32 or operation platform 34 connections.Tension part can be copper wire, iron wire etc..

It is arranged in limiting through hole 414 by the way that tension part is arranged, the freedom that fastener 41 is rotated along own axes can be limited Degree prevents fastener 41 from overcoming frictional force and nut is driven to rotate jointly.It can will be in fastener 41 in casting process in this way State locking, prevent short side 412 to be rotated into glade plane space 345.

For the ease of the movement of universal wheel 31, the upside of pile formula reinforcement cushion 10 is provided with backing plate 13, and backing plate 13 is located at Between pile formula reinforcement cushion 10 and universal wheel 31, so that slip scaffold 30 is more smooth when moving.
