Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model；
Appended drawing reference: 1- top plate, 2- position cylinder, 3- bottom plate, 4- head nuts, 5- screw thread adjusting rod, 6- force bearing disk, 7-
Tool clamping part.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
The embodiments of the present invention: a kind of accurate regulating system of self-control precast beam longitudinal slope, as shown in Fig. 1, including
Have a top plate 1,1 bottom of top plate is fixedly installed one group of positioning cylinder 2, be fixed on the bottom plate 3 of 2 lower section of positioning cylinder one group with
Positioning 2 position of cylinder is threaded into a head nut 4 in one-to-one silk head nut 4,5 bottom end of screw thread adjusting rod vertically, head end
Activity is caught in positioning tube body 2.
In use process, screw thread adjusting rod 5 is rotated by tool, since silk head nut 4 is fixed, then screw thread adjusting rod 5 is high
Degree can occur to rise or decline, and the 5 head end activity of screw thread adjusting rod is caught in positioning tube body 2, then its head end directly with top plate 1
Bottom contact realizes longitudinal slope adjustment so that 1 height of top plate changes.And be provided with positioning cylinder 2 can be to avoid top plate
1 there is the displacement of horizontal direction under external force, deviates predeterminated position.It can be realized to guarantee to be adjusted by the thread bar 5
The lifting or decline of top plate 1, when top plate 1 is in level, the length of screw thread adjusting rod 5 should be less than 1 bottom surface of top plate to 3 table of bottom plate
When the distance between face, in this way reduction by 1 height of top plate, screw thread adjusting rod 5 just has the space rotated down.
Equipped with measure scales on the silk head nut 4.The measure scales correspond to the turnning circle of screw thread adjusting rod 5, i.e.,
Indicate that screw thread adjusting rod 5 rotates the removable how many displacements of several circles.The displacement of screw thread adjusting rod 5 can be realized by the measure scales
Precisely adjust.
5 head end of screw thread adjusting rod is equipped with 1 force bearing disk 6, which can be improved the stress of screw thread adjusting rod 5
Area.
5 shaft of screw thread adjusting rod is equipped with 1 tool clamping part 7, which is to use work for convenience
Tool clamps screw thread adjusting rod 5.
The 5 shaft section of screw thread adjusting rod is polygonized structure, if shaft is circle, is clamped using tools such as spanners
It is firmly not easy to be turned after shaft, therefore sets polygonized structure for shaft, after clamping shaft using tools such as spanners very
It is easy just to be turned.
The screw thread adjusting rod 5 is made of finish rolling deformed bar, after finish rolling deformed bar head end jumping-up, processed filament head, i.e.,
Obtain fine thread.There is finish rolling deformed bar in construction site, is processed into screw thread adjusting rod 5 using finish rolling deformed bar, materials
It is very convenient.
The construction of the regulating system includes following steps:
(1) preparation of bottom plate 3.Pedestal basis uses C30 concreting, and pre-buried pedestal steel plate, pre-buried and tune is arranged
Save the fixation device of sleeve.
(2) finish rolling deformed bar and silk head nut 4 prepare:
1, reinforcing bar selects.According to Precast T-Beam weight, loading characteristic selects suitable finish rolling deformed bar, and determines reinforcing bar
Spacing.
2, special silk head nut 4.According to precast beam weight, loading characteristic, special silk head nut 4, silk head nut 4 has
The dual function of connection screw thread and measurement, and by experiment, the revolution of twisting finish rolling deformed bar is determined, on silk head nut 4
The relation curve of scale, it will be able to which the displacement of accurate control finish rolling deformed bar is adjusted.
3, finish rolling deformed bar is cut.According to precast pedestal height and steel plate thickness is adjusted, calculates finish rolling deformed bar
Length.When reinforcing bar is cut, notch should save smoothly and reinforcing bar axis is vertical, and end must not have warping phenomenon.
4, finish rolling deformed bar two ends are upset.Using button head machine by finish rolling deformed bar end jumping-up, jumping-up head is not if
It meets the requirements, jumping-up again should be cut, must not directly carry out secondary jumping-up.
5, end machining silk head thread.After end, the machining screw thread on die head threading machine.
6, grinding process.After finish rolling deformed bar processes, grinding process is carried out, guarantees that silk thread mouth is round and smooth.
7, antirust treatment.Antirust treatment is carried out to finish rolling deformed bar and silk head nut 4 using antirust paint.
8, the installation self-control accurate regulating system of precast beam longitudinal slope, top plate 1 are fixed by fixture, and bottom plate 3 passes through pre-buried solid
It is fixed.
9, finish rolling deformed bar is rotated, adjusts longitudinal slope according to design.Finish rolling spiral shell is adjusted according to design route longitudinal slope in use
Line reinforcing bar height, until longitudinal slope and design are consistent.
