[0002] At present, in the cumulative sliding installation construction of large-span block steel structures, due to assembly errors, external environmental influences (such as temperature changes, wind force) or the nature of the material itself, the steel structure may produce different degrees of deviation during the installation process. In order to solve the problem of adjusting the positioning error of the sliding structure during construction operations, in the process of sliding operations that require large-span steel structures, in order to adjust the positioning accuracy of the block steel structure, it is often necessary to place a small cylindrical steel under the structure, and use the jack to push up from the side and the rolling of the round steel for adjustment. However, it is often easy to slide sideways and roll beyond the amplitude, resulting in large errors, which is easy to cause adjustment reversal and may also cause safety accidents due to improper operation.

[0003] Therefore, an adjustment device is needed to improve the efficiency and one-time success rate of adjusting the span direction deviation of the large-span block steel structure by cumulative slip, save construction time, and provide more convenient and safe construction operations.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1 The large-span steel structure positioning error adjustment device shown includes: a supporting rolling component 10, a stop control component 20 and a structure pushing component 30; the supporting rolling component 10 includes a device base 11 and a rolling member arranged on the device base 11; the stop control component 20 and the structure pushing component 30 are installed on the device base 11, and are respectively located on both sides of the rolling round steel 12; the stop control component 20 includes a stop base plate 21 and a stop screw 22 threadedly matched with the stop base plate 21; the length direction of the stop screw 22 is arranged along the first direction; the structure pushing component 30 is used to push the steel structure (or sliding structure 40) to slide along the first direction to the end of the contact stop screw 22.

[0022] like Figure 1 As shown, the structure pushing assembly 30 includes a finished screw jack. The pushing direction of the finished screw jack is a first direction, and the axis of the finished screw jack coincides with the axis of the stop screw 22.

[0023] The device base 11 includes a device bottom plate, a groove 13 is provided on the device bottom plate, and a rolling element is provided in the groove 13. The rolling element includes a rolling round steel 12. In this embodiment, Figure 1 , Figure 2 As shown, there are three grooves 13, which are arranged at intervals along the first direction, and the first direction is the length direction of the bottom plate of the device. The width of each groove 13 along the first direction is greater than the diameter of the rolling round steel 12, and the rolling round steel 12 can roll along the first direction in the groove 13. The bottom of the groove 13 is a slope surface, and the side of the bottom of the groove 13 close to the structural pushing component 30 is lower than the side close to the stop control component 20. The slope of the slope surface cannot make the rolling round steel 12 move out of the groove 13, and can effectively disperse and relieve the pressure and stress of the rolling round steel 12. This helps to protect the base 11 and the sliding structure 40 of the device, reduce potential damage risks, and extend the service life of the device and structure. At the same time, such a design can also offset the risk of a large thrust on the rolling round steel 12 to push out of the groove 13, which can make the adjustment process smoother and more controllable.

[0024] like Figure 2As shown, the device base 11 also includes a baffle 14, which is vertically fixed on the device bottom plate, and the plate surface of the baffle 14 facing the groove 13 is used to connect or abut with the structure pushing component 30. The plate surface of the baffle 14 facing away from the groove 13 is connected with a rib plate, and the rib plate is also fixedly connected to the device bottom plate. The baffle 14 is vertically welded and fixed to the device bottom plate. There are five rib plates, which are spaced apart along the width direction of the device bottom plate. The rib plate is a triangular steel plate, one side of which is welded and fixed to the baffle 14, and the lower end is welded and fixed to the device bottom plate.

[0025] like Figure 1 As shown, the stop base plate 21 is connected to the device base plate by screws. The four corners of the stop base plate 21 are connected to the device base plate by a screw respectively.

[0026] like Figure 3 As shown, two supporting ear plates 23 are arranged on the stop base plate 21; threaded holes are arranged on the supporting ear plates 23 along the first direction, and the stop screw 22 passes through the two supporting ear plates 23 and is threadedly matched with the threaded holes.

[0027] like Figure 4 As shown, the middle part of the stop screw 22 is provided with an edge for facilitating its rotation, so that workers can complete the screwing work more easily and labor-savingly.

[0028] The stop screw 22 is used to manually adjust the end point of the position, and the adjustment is completed when the scale steel structure abuts against the head of the stop screw 22.

[0029] like Figure 5 As shown, when in use, the device bottom plate is located above the track (or track beam / sliding track 50), and the steel structure to be slidable is located above the device bottom plate. The static friction force generated by the device bottom plate and the track provides reaction force support for horizontal displacement.

[0030] The specific construction methods are as follows:

[0031] Install:

[0032] The supporting rolling assembly 10 and the stop control assembly 20 are fixed by screws to ensure that there is no relative displacement or relative sliding between the two, thereby ensuring the stability of the device.

[0033] The supporting rolling assembly 10 is placed between the sliding structure 40 and the sliding track 50 , and the sliding structure 40 is placed on three rolling round steels 12 . The directions of the supporting rolling assembly 10 and the stop control assembly 20 are determined by the direction in which the sliding structure 40 needs to be adjusted.

[0034] The lower end of the supporting rolling assembly 10 generates static friction with the track to provide a reaction force, and the final position of the stop screw 22 in the stop control assembly 20 is the end point of the sliding structure 40 adjusting the landing position.

[0035] After using a total station to determine the final position of the sliding structure 40, the final landing position of the sliding structure 40 can be fine-tuned by rotating the stop screw 22 in the stop control assembly 20 to control its fixed position in the threaded hole of the support ear plate 23 of the stop base plate 21.

[0036] Finally, the structural pushing component 30, i.e. the finished screw jack, is placed between the baffle 14 and the sliding structure 40. The reaction force of the baffle 14 supporting the rolling component 10 is used to push the sliding structure 40 to translate on the rolling round steel 12 until it contacts the stop control component 20, and the adjustment is completed.

[0037] use:

[0038] The stop screw 22 is held by hand and the end point of the sliding structure 40 is controlled by rotating the stop screw 22 .

[0039] The finished screw jack is used to gently press against the sliding structure 40 and push it, so that the sliding structure 40 slowly moves horizontally on the rolling round steel 12 .

[0040] When the sliding structure 40 abuts against the stop screw 22, the error adjustment is completed and the finished screw jack is unloaded.

[0041] tear down:

[0042] By rotating the stop screw 22 and unloading the force of the finished screw jack, there is no force acting on the device and the sliding structure 40 in the horizontal direction.

[0043] Place the finished screw jack vertically against the bracket welded on the side of the sliding structure 40, lift the structure so that there is no vertical force between the device and the sliding structure 40, withdraw the device, and the dismantling is completed.

[0044] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
