Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
Example (b):
referring to fig. 1-3, fig. 1 is a drawing device 100 for stretching according to the present invention. And the tension dedicated device 100 may be used to support the tension member 200, and may adjust the placement position of the tension member 200 such that the tension passage of the tension member 200 is parallel to the extending direction of the steel strand provided on the bottom side of the precast capping beam 300.
In a particular embodiment, the precast capping beam 300 comprises a first inclined side and a second inclined side. The included angle formed by the first inclined side face and the construction ground is a first acute angle, a plurality of steel strands 310 extend out of the first inclined side face, each steel strand is arranged in parallel, the axis of each steel strand is inclined in the vertical direction, and a second acute angle is formed between the first inclined side face and the ground. Therefore, the tensioning member 200 can be placed on the tensioning device 100, and the placement position of the tensioning member 200 can be adjusted by the tensioning device 100, so that the tensioning channel can be matched and connected with the plurality of steel strands 310 at the corresponding position.
Of course, the operation of the dedicated tensioning device 100 and the plurality of steel strands 310 disposed on the second inclined side surface is the same as that in the above embodiment, and will not be described again here.
Preferably, the tension dedicated device 100 includes, for example, a support base 10 and an adjustment portion 20. One side of the supporting seat 10 is provided with a tension member installation groove 11 for installing the tension member 200, and the adjusting part 20 is provided on the opposite side of the supporting seat 10; wherein, the adjusting part 20 can adjust the inclination angle and height of the supporting seat 10.
For example, in combination with the actual construction process, the tensioning member 200 is a jack structure, the support seat 10 is an arc-shaped annular structure, the top end of the support seat is provided with an arc-shaped mounting groove adapted to the jack structure, wherein the arc-shaped mounting groove is inclined in the vertical direction, the opening of the arc-shaped mounting groove faces the precast cover beam 300, and the bottom side of the arc-shaped mounting groove is provided with a limiting rib 12 to prevent the tensioning member 200 from being mounted on the arc-shaped mounting groove and sliding out along the bottom of the arc-shaped mounting groove. In order to make it more convenient to mount or dismount the tensioning member 200, the central angle corresponding to the ring structure may be smaller than 180 °, and the circular angle is, for example, 120 °, so that the ring structure partially wraps the outer surface of the tensioning member 200, and the tensioning member 200 can be mounted to the circular arc-shaped mounting groove along the opening corresponding to the ring structure, and is also convenient to dismount therefrom.
Preferably, the adjusting part 20 includes a lifting assembly and a base 23. One end of the lifting assembly is connected to one side of the supporting seat 10 far away from the tension member mounting groove 11, namely, the lower end of the supporting seat 10; the base 23 is fixedly connected with the other end opposite to the lifting component, and the base 23 and the supporting seat 10 clamp the lifting component.
Further, the lifting assembly comprises at least one telescopic member 21; the extensible member 21 includes a fixed portion 212 and an extensible portion 211. One end of the fixing part 212 is connected to the base 23, and the other end opposite to the fixing part is provided with a telescopic opening which is communicated with an installation space inside the fixing part 212; the telescopic part 211 is telescopically arranged in the installation space, and one end of the telescopic part 211, which is far away from the base 23, is movably connected with the support seat 10.
For example, the relative movement of the telescopic part 211 in the installation space is adjusted to enable the supporting seat 10 movably connected with the telescopic part to move away from or close to the base 23. Specifically, when the telescopic portion 211 moves in the direction away from the base 23 in the installation space, it drives the supporting seat 10 to also move in the direction away from the base 23, and in contrast, in order to make the supporting seat 10 move in the direction close to the base 23, it is only necessary to make the telescopic portion 211 move in the direction close to the base 23 in the installation space.
Preferably, the telescopic portion 211 is rotatably connected to the support base 10. In a specific embodiment, in combination with the above examples, the rotating connection may be a shaft connection, the telescopic member 21 is, for example, a hydraulic cylinder, which drives the supporting seat 10 to perform a lifting motion, and since the weight of the jack is relatively large, on one hand, the side turning during the lifting process is avoided, and on the other hand, in order to enable the supporting seat 10 to stably perform the lifting motion, the number of the hydraulic cylinders is four, wherein one hydraulic cylinder is respectively disposed at each of four corners of the supporting seat 10 near the bottom surface of the base 23. Since the jack is laid on the support base 10 and is disposed along the length direction thereof, specifically, two hydraulic cylinders disposed along the width direction of the support base 10 are connected by the same controller, and then four hydraulic cylinders are controlled by two controllers.
In the actual adjusting process, one of the two hydraulic cylinders connected to the controller can be controlled by the controller to synchronously extend or contract, and since the bottom of the support seat 10 is connected with the telescopic part 211 through a shaft, at this time, the support seat 10 is inclined in the vertical direction along the length direction thereof, so that a high position is formed on one side and a low position is formed on the opposite side, wherein the positions of the two hydraulic cylinders in the extending state correspond to the high position, and the positions of the two hydraulic cylinders in the contracting state correspond to the low position. And the support seat 10 is continuously adjusted by the two controllers, so that the tensioning channel of the jack can be adapted to the steel strand 310 at the corresponding position, and the two are connected in a matching manner to perform tensioning operation.
In another embodiment, the lifting assembly may also be an internally and externally threaded rod assembly, for example. Wherein, interior external screw rod subassembly includes first outer screw rod, the outer screw rod of second and internal thread pipe. The first outer screw rod enters the inner threaded pipe from the opening of the first end to be in threaded connection with the inner threaded pipe; and oppositely, the second external threaded rod enters the internal threaded pipe from the opening of the second end and is in threaded connection with the second external threaded rod. Wherein, the end part of the first outer screw rod far away from the first end is fixedly connected with the base 23; and one end of the second external screw rod, which is far away from the first external screw rod, is connected with the supporting seat 10 shaft. Therefore, the second externally threaded rod can rotate relative to the internally threaded tube along the matching thread track of the two by adjusting the rotation of the internally threaded tube, namely, move away from or close to the first externally threaded rod, so as to drive the supporting seat 10 to move away from or close to the base 23.
More specifically, the number of the inner and outer threaded rod assemblies may be four, and the arrangement manner thereof is the same as that of the four hydraulic cylinders, and the description thereof is omitted. One or more of the four inner and outer threaded rod assemblies can then be adjusted to cause the support base 10 to assume an inclined setting. For example, two of the inner and outer threaded rod assemblies provided along the width direction of the support base 10 are adjusted so that the support base 10 assumes an inclination in the vertical direction.
On one hand, the height of the supporting seat 10 is adjusted to rise or fall through the inner threaded rod assembly and the outer threaded rod assembly, or the inclination condition of the supporting seat 10 is changed, so that the operation is simple; on the other hand, the inner threaded rod and the outer threaded rod have the advantages of simple structure and low manufacturing cost.
Preferably, the adjustment portion 20 further includes a rotation assembly, for example. Wherein, the rotating assembly is rotatably connected to one side of the base 23 close to the lifting assembly, and the lifting assembly is arranged on one side of the rotating assembly far away from the base 23.
Further, the rotating assembly includes, for example, a turntable 22. Specifically, the turntable 22 is provided with opposing first and second sides; wherein, a connecting piece which is rotationally connected with the base 23 is arranged on the first side; and a positioning piece for mounting the lifting assembly is arranged on the second side.
For example, the connecting member is a rotating shaft, opposite to the rotating shaft, and a shaft hole is formed in the base 23 and is rotatably connected with the rotating shaft, so that the rotating plate 22 can rotate horizontally relative to the base 23 through the rotating shaft and the shaft hole, and further the supporting seat 10 can be driven to rotate horizontally. In addition, the positioning element is circumferentially and fixedly connected to the turntable 22, and the positioning element may be an installation kit for installing the lifting assembly, so that the lifting assembly is detachably connected to the turntable 22 through the installation kit.
Preferably, the tensioning-specific device 100 also comprises, for example, a moving assembly. The moving assembly is provided at the bottom of the tension dedicated device 100, and it is provided with a moving wheel 40. The number of the moving wheels 40 may be four, and the moving wheels are respectively disposed at four corners of the base 23. In order to allow the tension-dedicated device 100 to move or rotate flexibly, the moving wheels 40 may be universal wheels.
For example, since the space between the position of the prefabricated capping beam 300 with the steel strand 310 at the bottom side and the construction ground is narrow, the tension member 200 can be pre-installed on the supporting seat 10, and the special tension device 100 is moved into the space by the moving wheel 40, so that the installation difficulty is reduced; after the tensioning operation is completed, the tensioning member 200 does not need to be detached from the tensioning-dedicated device 100, and both can be removed from the space for the next tensioning operation. Thereby avoiding frequent disassembly and assembly.
Preferably, the moving assembly is provided with a locking structure 30 at a corresponding position of the moving wheel 40, wherein the locking structure can be adjusted to lock or unlock the moving wheel 40.
For example, if the tensioning-dedicated device 100 is moved, the locking structure 30 is not in contact with the corresponding moving wheel 40, i.e. the two are in a released state; the locking structure 30 may be made to lock the corresponding moving wheel 40 when it is desired to secure the tensioning-specific device 100, for example during the tensioning process.
In order to better understand the technical solution of the present invention, the following will describe the technical solution of the present invention in detail with reference to the contents of fig. 1-3:
in a construction site, the steel strand at the bottom of the precast bent cap 300 needs to be tensioned, and since a construction space formed between the steel strand 310 and the construction ground is narrow, if the tension member 200 is installed on the tension dedicated device 100 in the construction space, the installation difficulty increases. Thus, before entering the construction space, the tension member 200 may be pre-installed on the support base 10, and the tension-dedicated apparatus 100 equipped with the tension member 200 is moved into the construction space by the moving wheel 40.
In order to avoid interference on the steel strands 310 at corresponding positions, the special tensioning device 100 is arranged on one side of the plurality of steel strands 310, and the supporting seat 10 is pre-adjusted, for example, the inclination angle of the supporting seat 10 in the vertical direction can be adjusted first, and the hydraulic cylinders connected with the supporting seat 10 can be controlled by the two controllers until the inclination angle of the tensioning member 200 arranged on the supporting seat 10 is adapted to the extending direction of the steel strands 310, that is, the tensioning channel is parallel to the extending direction of the steel strands 310; the height of the supporting seat 10 can be adjusted to be adapted to the height of the corresponding steel strand 310, specifically, since the tensioning member 200 is inclined in the vertical direction, there are a corresponding high end and a corresponding low end, and the high end and the end of the corresponding steel strand 310 are at the same height through the telescopic action of the hydraulic cylinder; then, the position of the tension member 200 in the horizontal direction can be adjusted, that is, the rotating disc 22 is rotated to make the end surface of the high end correspond to the end surface formed by the ends of the plurality of steel strands 310 at the corresponding position, which indicates that the height adjustment is completed at this time; then, the special tensioning device 100 is moved by the moving wheel 40 so that the plurality of steel strands 310 can correspondingly enter the tensioning channel, the special tensioning device 100 is stopped from moving until the matching connection degree of the two meets the construction requirement, then the moving wheel is locked by the locking structure 30 so as to prevent the special tensioning device 100 from moving, and finally tensioning operation is performed.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the scope or spirit of the present invention, and the scope of the present invention is defined by the appended claims.
