Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The words "upper", "lower", "left" and "right" when used herein are merely intended to designate corresponding upper, lower, left and right directions in the drawings, and do not limit the structure thereof.
As shown in fig. 1 and 2, the lateral limiting device for the jacking of a building comprises a box-shaped opening slot 1 and a limiting rail 2 extending vertically.
The box-type opening clamping groove 1 comprises a box body 11 with a rectangular ring structure. The box 11 is provided with a connecting skirt 12. An opening 13 is provided on one side wall of the case 11.
The limiting rail 2 comprises a connecting vertical plate 21, a longitudinal vertical plate 22 for transverse limiting and a transverse vertical plate 23 for longitudinal limiting. The connecting vertical plate 21 is provided with a plurality of connecting pieces 24. The longitudinal vertical plate 22 is arranged in the opening 13 in a penetrating way.
The lateral sides of the two transverse sides of the longitudinal vertical plate 22 are abutted with the opening 13 of the box-shaped opening clamping groove 1, and transverse bidirectional limiting is realized in a simple structure mode.
One end of the vertical plate 22 is connected with the connecting vertical plate 21, and the other end is connected with the transverse vertical plate 23.
The connecting vertical plate 21, the longitudinal vertical plate 22 and the transverse vertical plate 23 are connected together in an I shape. The transverse vertical plate 23 is arranged in the box body 11 in a penetrating way.
A plurality of rib plates 33 distributed along the up-down direction are connected between the vertical connecting plate 21 and the vertical plate 22, and the structural strength is good.
The longitudinal surface of the transverse vertical plate 23 is abutted with the inner surface of the clamping groove of the box-shaped opening 13, namely the inner side surface of the side wall of the box body 11 provided with the opening 13, so that longitudinal one-way limiting is realized.
The method for jacking and limiting comprises the following steps: screws 31 penetrate through connecting holes in the connecting skirtboard 12 and then are connected with a lifted upper part 32, namely a beam, of the building, so that the box-type opening clamping groove 1 is fixed. The screw 31 is connected with the original lower structure 34 of the building, specifically a stand column, after penetrating through the connecting hole on the connecting sheet 24, so as to realize the fixation of the limiting track 2. After the box-type opening clamping groove 1 is connected with the upper part of the building to be jacked and the limiting track 2 is connected with the original lower part structure of the building, the building is cut off by the upper part 32 to be jacked and the original lower part structure 34 to be jacked. This way, it is possible to prevent the generation of horizontal displacement during the truncation. In the jacking process, the longitudinal vertical plate 22 is matched with the opening 13 to realize transverse bidirectional limiting, and the transverse vertical plate 3 is matched with the box body 11 to realize longitudinal east-west limiting.
The second embodiment, as shown in fig. 3, is different from the first embodiment in that: the box-shaped opening clamping groove 1 is connected with a rotating frame 4. The turret 4 comprises two laterally distributed coaxial stub shafts 41. The stub shaft 41 is rotatably connected to the housing 11. The box body 11 is also provided with a jackscrew 46 which can be used for tightly jacking the spindle head 41 and preventing the spindle head from rotating. A longitudinal connecting rod 42 is connected to the stub shaft 41. The longitudinal connecting rod 42 is provided at each end thereof with a roller mounting pin 43. The roller mounting pin 43 extends in the longitudinal direction. One of the roller mounting pins 43 on the two stub shafts 41 is connected together. The roller mounting pin 43 is connected to a clamping roller 44. The two clamping rollers 44 on the same stub shaft form a pair of clamping rollers. Two clamping rollers 44 of the pair of clamping rollers are longitudinally distributed on both sides of the transverse vertical plate 23. The two clamping rollers 44 of a pair of clamping rollers have equal radii. Two clamping rollers 44 in a pair of clamping rollers are equal in distance from the transverse vertical plate 23, so that the clamping rollers on two sides can be prevented from being adjusted to be reliably abutted to the transverse vertical plate and are limited in a two-way reliable manner due to the fact that the linear speeds of the clamping rollers on two sides of the transverse vertical plate are different in the jacking process.
The middle part of the longitudinal connecting rod 42 is provided with a clamping rolling ball 45. The total two holding rolling balls on the two shaft heads form a pair of holding rolling balls. Two clamping rolling balls 45 in the pair of clamping rolling balls are butted on two sides of the transverse vertical plate 23 along the transverse direction, so that transverse bidirectional limiting is realized.
A total of two gripping balls on the two stub shafts 41 constitute a pair of gripping balls.
As shown in fig. 3, the rotating frame 4 is used for driving the pair of clamping rollers 44 to abut against and separate from the transverse vertical plate 23, so that longitudinal bidirectional limiting is realized, resistance generated by limiting during lifting is small, the longitudinal bidirectional limiting can be realized without precision guarantee during assembly, namely, both longitudinal sides abut against, after the assembly is completed, the rotating frame 4 is rotated to enable the clamping rollers 44 to abut against the vertical plate of the air route for longitudinal bidirectional limiting, and therefore the precision requirement during assembly is low.
The transverse vertical plate 23 is provided with a circular arc-shaped supporting groove matched with the clamping rolling ball, so that the reliability in limiting can be improved. The holding rolling ball 45 is movably connected in the circular arc-shaped supporting groove.
Referring to fig. 3, when the invention is installed, the jackscrew 46 is firstly loosened, and the rotary shaft head 41 drives the clamping roller 44 to rotate to be separated from the transverse vertical plate 23. After the installation, the shaft head is rotated until the clamping roller 44 is abutted with the transverse vertical plate 23, so that the longitudinal bidirectional limiting is realized. And (5) tightly pressing the jackscrew. And cutting off the jacked upper part 32 of the building and the original lower part structure 34 of the building, and forming a cutting-off opening 35 for cutting off the jacked upper part of the building and the original lower part structure of the building along the horizontal direction between the jacked upper part 32 of the building and the original lower part structure 34 of the building after cutting off. The cut-off 35 is located right below the box-type opening clamping groove 1, and when the box-type opening clamping groove is accidentally descended during jacking, the box-type opening clamping groove can prevent the building from being damaged due to excessive descent.
The present invention has been further described with reference to specific embodiments, but it should be understood that the detailed description should not be construed as limiting the spirit and scope of the present invention, and various modifications made to the above-described embodiments by those of ordinary skill in the art after reading this specification are within the scope of the present invention.
