In other words, the adjustable supporting jig frame can meet the supporting requirements in various occasions. The jig mainly comprises a base 1, a first supporting rod 2, a second supporting rod 3, a bowl-shaped nut 4, a screw 5 and a supporting plate 6. The base 1 is used as the foundation of the whole supporting jig frame, is firm and stable in design and can effectively bear the weight of the whole jig frame. On base 1, be rectangular array and be provided with four first bracing pieces 2, such design has not only guaranteed the stability of bed-jig, has also made things convenient for simultaneously adjusting the whole height of bed-jig. Each second supporting rod 3 can be telescopic in the corresponding first supporting rod 2, and the height of the jig frame can be flexibly adjusted according to the requirement by the design. Meanwhile, the upper end of the second supporting rod 2 is provided with a rotatable cover provided with a bowl-shaped nut 4, and the bowl-shaped nut 4 is designed to be tightly matched with the second supporting rod 3 so as to prevent deviation in the rotation process. The bowl-shaped nut 4 is connected with a screw 5 in a matching way, and the screw 5 can be driven to move up and down by rotating the bowl-shaped nut 4. The lower end of the screw 5 is movably inserted into the second supporting rod 3, so that the screw 5 can perform stable lifting movement in the second supporting rod 3. Meanwhile, the upper end of the screw 5 is connected with the supporting plate 6, the supporting plate 6 is used as a bearing surface of the whole jig frame, and the design is smooth and firm, so that articles needing to be supported can be effectively borne.
For example, the bowl-shaped nut 4 may be directly covered on top of the second support rod 3. Of course, the bowl nut 4 can be smoothly rotated by connecting the bowl nut and the bowl nut by adopting a bearing.
In the use process, the base 1 is placed below the body to be supported, and the body to be supported is placed on the supporting plate 6; the second support rod 3 is controlled to extend or retract into the first support rod 2, so that the coarse adjustment of the height is realized; by controlling the bowl-shaped nut 4 to rotate clockwise or anticlockwise, the driving screw 5 is driven to ascend or descend, so that the fine adjustment of the height is realized. That is, the user can adjust the telescopic length of the combination of the first support bar 2 and the second support bar 3 as required, thereby achieving a rough adjustment of the overall height of the jig frame.

The adjustable supporting jig frame is supporting equipment with comprehensive functions, simple and convenient operation and strong stability, and is suitable for various occasions needing flexible adjustment of supporting height.
Preferably, as shown in fig. 2, a rotating handle 12 is arranged on the bowl-shaped nut 4, so that the bowl-shaped nut is convenient to hold and rotate.
In one embodiment, as shown in fig. 1, the base 1 includes two opposite and parallel sliding rails 100, and a connecting rod 101 connecting the two sliding rails 100. For example, two parallel sliding rails 100 are respectively connected with a connecting rod 101 near two ends, and two ends of the connecting rod 101 are detachably connected with the corresponding sliding rails 100, for example, the two ends are connected by adopting a connecting block and a bolt in a matching manner.
Each sliding rail 100 is provided with two sliding components 7 in sliding fit, each sliding component 7 and the corresponding sliding rail 100 can be locked and fixed, and each sliding component 7 is correspondingly connected with a first supporting rod 2. Two adjacent first support rods 2 are connected by a connecting tie rod 8, and the length of the connecting tie rod 8 between the two first support rods 2 on the same slide rail 100 is adjustable.
Specifically, when the distance between the two first support rods 2 on the same slide rail 100 needs to be adjusted, firstly, the locking state of the sliding components 7 and the corresponding slide rail 100 is released, the distance between the two sliding components 7 is changed to the required distance, and meanwhile, the length of the connecting tie rod 8 is adjusted; finally, the sliding assembly 7 is locked and fixed on the corresponding sliding rail 100, so that the distance between two adjacent first supporting rods 2 can be quickly adjusted to adapt to different supporting requirements.
Compared with the steel plate used as the jig frame foundation, the base 1 of the embodiment is more stable in support and saves materials. Specifically, if the steel plate foundation is adopted and needs to be fully paved, the consumption of the steel plate is very large, the steel plate is connected with the support column in a bolt mode, holes are formed according to actual requirements of the site, the formed holes cannot be recycled, and the large-area holes are formed, so that labor is wasted, and the strength of the steel plate is reduced. And when the high bolt is fixed with the steel plate, after the steel plate is suspended, the nut is fixed below the steel plate to fasten the high bolt, usually the outer leakage wire of the high bolt is 2-3 wires, the exposed wire is more in contact with the ground if the exposed wire is more buckled, the steel plate cannot be suspended closely to the ground to play a role of not taking a foundation, and the outer leakage wire is short and cannot be fastened. Therefore, compared with the prior art, the base design of the embodiment not only can flexibly adjust the distance, be recycled, and has stable and reliable structure, but also has low cost.
Preferably, as shown in fig. 4 and 5, the sliding rail 100 is an i-shaped sliding rail, and the sliding assembly 7 includes a sliding plate 700 slidably disposed on an upper end surface of the i-shaped sliding rail, and an adjustable lock 701 for locking and fixing the sliding plate 700 to the upper end surface of the i-shaped sliding rail; the sliding plate 700 is fixedly connected with the corresponding first supporting bar 2. The I-shaped sliding rail is made of double-spliced I-steel by way of example.
That is, the locking and fixing state or the unlocking state between the sliding plate 700 and the i-shaped sliding rail can be realized by controlling the adjustable lock 701.
As a preferred embodiment, referring to fig. 4 and 5, the adjustable lock 701 includes C-shaped buckles 701a arranged in mirror image and pressed on the slide plate 700, the top ends of the two C-shaped buckles 701a are respectively connected with connecting plates 701b arranged opposite to each other, and the two connecting plates 701b are connected by an adjusting bolt 701C. Specifically, when the slide plate 700 needs to be locked and fixed to the upper end surface of the i-shaped slide rail, the adjusting bolt 701C pulls the two connecting plates 701b to approach each other, so as to drive the two C-shaped buckles 701a to be respectively clamped on two sides of the upper end surface of the i-shaped slide rail.
In other words, the present embodiment adopts a simple design similar to a hoop, so that the connection state between the slide plate 700 and the i-shaped slide rail can be conveniently and rapidly controlled, and when the two connecting plates 701b are pulled close to each other by the control adjusting bolt 701C, the two connecting plates 701b respectively drive the corresponding C-shaped buckles 701a to approach each other until the two C-shaped buckles 701a are respectively clamped at two sides of the upper end surface of the i-shaped slide rail, so that the locking and fixing can be realized. When the locking is required to be released, the adjusting bolt 701c is only required to be reversely screwed for unlocking.
Preferably, a chamfer is provided inside the C-shaped buckle 701a, and when the adjusting bolt 701C pulls the two connection plates 701b toward each other, the clamping will be more and more tight, and even when the connection plate bottom plate is deformed or the thickness deviation of the connection plate is too large, the clamping of the C-shaped buckle 701a can be ensured.
In an embodiment, as shown in fig. 1 and 2, the connecting tie rod 8 between two first support rods 2 on the same slide rail 100 includes a sleeve 800 and telescopic rods 801 telescopically connected to two ends of the sleeve 800, one end of the telescopic rod 801 facing away from the sleeve 800 is connected to one first support rod 2, and the other end of the telescopic rod 801 facing away from the sleeve 800 is connected to the other first support rod 2. That is, the length adjustment of the connecting tie bar 8 is achieved by extending the telescopic rod 801 into or out of the sleeve 800, compared with the arrangement of a plurality of ear plates around the support column, the design mode of the embodiment is simpler to operate and control and has low design cost (because the number of the ear plates is large, and labor and time are wasted in processing) because the ear plates are fixed and the length of the X connecting system is also fixed, and the distance can be adjusted only by changing the connection positions of the ear plates.
Preferably, as shown in fig. 2, the sleeve 800 is screwed with the corresponding telescopic rod 801, that is, the length of the connecting tie rod 8 can be adjusted quickly by screwing, and the reliability of the screwing is high.
Illustratively, an internal thread is provided in the sleeve 800, and an external thread is provided at the end of the telescoping rod 801 connected to the sleeve 800, which are in threaded connection. It should be appreciated that the threads on the two telescoping rods 801 are threaded in opposite directions.
Preferably, as shown in fig. 1 to 3, an ear plate 9 is provided on each first support rod 2, and the connection tie rod 8 is connected to the corresponding first support rod 2 through the ear plate 9. In more detail, the connecting tie rod 8 is connected to the ear plate 9 by a bolt assembly. The ear plate 9 is illustratively fixed to the first support bar 2 by means of welding.
More preferably, as shown in fig. 1 and 2, two adjacent first support rods 2 are connected through two connecting tie rods 8 which are arranged in an X shape, so that the stress is better, and the connection reinforcement is more reliable.
In an embodiment, as shown in fig. 1 to 3, elevation adjusting holes 10 are formed in the first support rod 2 and the second support rod 3, and bolts 11 are inserted into the elevation adjusting holes 10 opposite to the first support rod 2 and the second support rod 3, so that the first support rod 2 and the second support rod 3 can be connected in a telescopic manner, and the adjustment is convenient. Illustratively, the elevation adjustment holes 10 are uniformly formed.
In the supporting jig provided by the embodiment, after the positions of the supporting rods are adjusted, the four supporting rods are fixed with the sliding rail through the sliding component, and according to the fact that the assembled components are integrally assembled or n+1 segments are needed for the segments to be assembled, the bridge is ensured to be linear, longitudinal slope and pre-arched, and the elevation is adjusted according to the elevation. In the face of beam bridge blocks with different section heights and different spans, if a long line method is adopted for assembly or integral assembly or a longitudinal slope is larger, a supporting rod (coarse adjustment) +bowl-shaped nut and a screw rod (fine adjustment) are needed to be matched with each other to adjust the elevation, and the measured line type, the transverse slope, the longitudinal slope and the pre-arching value are adjusted by a fine adjustment structure according to the design values of each point, so that the beam bridge blocks meet the design requirement, and the beam bridge blocks are more accurate and convenient to operate compared with the traditional method for adjusting elevation by increasing and decreasing steel plates. For the assembly of bridges with complex space structures such as large-scale and extra-large-scale beam bridges, if the distance needs to be adjusted according to the stress points of the beam plates, the relative position of the support rods can be adjusted on the double-assembly I-steel base at will according to the required distance, and the connecting tie bars are correspondingly lengthened or shortened to be connected with the lug plates on the support rods, so that the beam bodies with different stress points in different forms can be conveniently and rapidly adjusted; when the bridge deck plate is large in space size and unstable in structural irregular variable stress, multiple groups of supporting jig frames can be additionally arranged, the supporting jig frames of all groups are connected by utilizing connecting tie bars, assembly can be completed without adding other auxiliary measures, the working procedure is simple and convenient, assembly type construction can be achieved, the material recycling rate is improved, and the construction efficiency is improved. The support rod and the ground are paved with double-spliced I-shaped steel rails, the support rod and the connecting tie rod are detachably and telescopically connected, and the double-spliced I-shaped steel rails can be selectively used according to specific situations on site, and are convenient to install and detach and capable of being recycled.
