Description

Technical Field

[0001] The present application relates to the technical field of building deviation correction, and in particular to a simple building jacking device. Background Art

[0002] During the long-term use of buildings, there will be phenomena such as soft foundation soil, insufficient foundation bearing capacity and uneven settlement. In addition, unreasonable survey and design or the impact of natural disasters such as earthquakes will cause the building to tilt. After the building tilts, due to the high center of gravity of the building structure, its structural center of gravity is unstable. The tilted building will generate secondary additional bending moment on the foundation, which will further aggravate the uneven settlement of the building, accelerate the tilt rate of the building, and cause cracks in the upper structure wall. The building tilt will lead to huge structural safety hazards, and effective correction technical measures must be taken as soon as possible to deal with it.

[0003] Among the related technologies, the broken column jacking method is a commonly used technology for correcting building deviations. Its working principle is to set the jacking point on the base structure, use the base structure as a reaction platform, cut off the frame columns, jack up the upper structure, and restore the columns after jacking into place.

[0004] Regarding the aforementioned related technologies, the inventors believe that the existing broken-column jacking method for rectifying deviations consumes considerable time and cost. For example, a concrete or steel reaction platform must be set up before jacking, which incurs a significant workload and incurs high costs. Since setting up the concrete or steel reaction platform takes a considerable amount of time, it significantly prolongs the overall construction period for rectifying deviations, resulting in reduced construction efficiency. Therefore, further improvements are possible. Summary of the Invention

[0005] In order to reduce the overall construction period of building rectification and improve the construction efficiency of building rectification, the present application provides a simple building jacking device.

[0006] The present application provides a simple building lifting device that adopts the following technical solutions:

[0007] A simple building jacking device includes a first lifting platform and a second lifting platform. The first lifting platform and the second lifting platform are both used to be fixed on the side wall of a structural column. The first lifting platform is located below the second lifting platform. A jack is installed between the first lifting platform and the second lifting platform. The jack is used to support the second lifting platform.

[0008] By adopting the above technical solution, during construction, the first lifting platform and the second lifting platform are respectively fixed to the side walls of the structural column, and then the jack is installed between the first lifting platform and the second lifting platform for supporting operation, and then the structural column between the first lifting platform and the second lifting platform is broken, and the structural column is lifted and corrected by the jack, thereby eliminating the work process of casting the foundation and the lifting platform, greatly shortening the overall construction period of the building correction, and improving the construction efficiency of the building correction.

[0012] By adopting the above technical solution, support ribs perpendicular to the bottom of the support top plate are set, and the support ribs are used to increase the rigidity of the support top plate so that it can withstand a larger load. Multiple support ribs can effectively disperse the load and reduce deformation or damage caused by local stress concentration during the working process of the jack, thereby increasing the durability of the support top plate and extending its service life.

[0013] Optionally, a supporting side plate is provided at the bottom of the supporting top plate, the supporting side plate and the supporting top plate are arranged perpendicular to each other, and the supporting rib plate and the supporting side plate are arranged perpendicular to each other.

[0014] By adopting the above technical solution, the supporting top plate, supporting side plates and supporting ribs are arranged perpendicular to each other to form a stable frame structure, which helps to improve the stability and bending resistance of the lifting plate.

[0019] Optionally, lifting connecting rods are provided on both sides of the lifting plate, and the lifting connecting rods are hinged to the first connecting rod.

[0022] By adopting the above technical solution, the lifting and tightening column is hinged to the second connecting rod, so that there is freedom of relative rotation between the tightening column and the second connecting rod, so that the tightening column can be flexibly raised and lowered.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a simple building jacking device.

[0034] Reference Figure 1 、 2A simple building jacking device includes a first lifting platform 2 and a second lifting platform 3. The first lifting platform 2 and the second lifting platform 3 are both used to be fixed on the side wall of the structural column 1. The first lifting platform 2 is located below the second lifting platform 3. A jack 4 is installed between the first lifting platform 2 and the second lifting platform 3. A plurality of safety support columns 9 for assisting the jack 4 for supporting and protecting are arranged between the first lifting platform 2 and the second lifting platform 3 to prevent the jack 4 from becoming unstable. The plurality of safety support columns 9 can maintain the stability between the first lifting platform 2 and the second lifting platform 3, prevent damage caused by the instability of the jack 4, and enable the jack 4 to better support the second lifting platform 3.

[0035] During the actual construction process, the first lifting platform 2 and the second lifting platform 3 are respectively fixed on the side walls of the structural column 1, and then the jack 4 is installed between the first lifting platform 2 and the second lifting platform 3 for supporting operation, and then the structural column 1 between the first lifting platform 2 and the second lifting platform 3 is broken, and the structural column 1 is lifted and corrected by the jack 4, thereby eliminating the work process of casting the foundation and the lifting platform, greatly shortening the overall construction period of the building correction, and improving the construction efficiency of the building correction.

[0036] It should be noted that the structure and connection method of the first lifting platform 2 are the same as those of the second lifting platform 3, the only difference being that they are symmetrically arranged along the radial direction of the structural column 1 during installation. The following description is based on the structure of the first lifting platform 2, and the structure of the second lifting platform 3 is not repeated.

[0037] refer to Figure 1 、 2 Specifically, in this embodiment, the first lifting platform 2 includes a pair of first connecting rods 5 and a pair of second connecting rods 6. The two first connecting rods 5 are symmetrically installed on both sides of the structural column 1, and the two second connecting rods 6 are also symmetrically installed on both sides of the structural column 1. The first connecting rod 5 and the second connecting rod 6 are arranged on the same side, and the middle part between the first connecting rod 5 and the second connecting rod 6 is hinged, and the first connecting rod 5 and the second connecting rod 6 are connected by bolts. The bolts pass through the second connecting rod 6 and the first connecting rod 5 in turn and are locked by nuts.

[0038] Among them, a lifting plate 7 and a tightening column 8 are hinged between the two first connecting rods 5, and a lifting plate 7 and a tightening column 8 are hinged between the two second connecting rods 6. The lifting plate 7 and the tightening column 8 are both fixed on the side walls of the structural column 1. The lifting plate 7 and the tightening column 8 are relatively arranged on both sides of the structural column 1, and the lifting plate 7 is located below the tightening column 8. The jack 4 is placed on the lifting plate 7 for work.

[0039] During actual use, the lifting plate 7 and the clamping column 8 are installed on the side wall of the structural column 1, and the lifting plate 7 and the clamping column 8 are fixedly connected by the first connecting rod 5 and the second connecting rod 6 connected by cross rotation, so that the lifting plate 7 and the clamping column 8 are fixedly set on the side wall of the structural column 1. The setting of the lifting plate 7 can place the jack 4. Through the jacking of the jack 4, the first connecting rod 5 and the second connecting rod 6 are separated, and the distance between the lifting plate 7 and the clamping column 8 is increased, so that the clamping column 8 is pressed against the structural column 1, making the first lifting platform 2 more firmly fixed, thereby realizing the jacking and correction of the structural column 1.

[0040] refer to Figure 1 、 3 Specifically, in this embodiment, the lifting plate 7 includes a supporting top plate 71 and a plurality of supporting ribs 72 mounted on the bottom of the supporting top plate 71. The plurality of supporting ribs 72 are evenly spaced along the length of the supporting top plate 71, and the supporting ribs 72 and the supporting top plate 71 are perpendicular to each other. In this embodiment, there are four supporting ribs 72.

[0041] In addition, a support side plate 73 is fixedly connected to the bottom of the support top plate 71 near the side of the structural column 1. The support side plate 73 and the structural column 1 are arranged in close contact with each other, and the support side plate 73 and the support top plate 71 are arranged perpendicular to each other. The support side plate 73 is also arranged perpendicular to the support rib plate 72, so that the support top plate 71, the support rib plate 72 and the support side plate 73 are in a perpendicular state to each other.

[0042] In actual use, support ribs 72 are provided at the bottom of the support top plate 71, perpendicular thereto. The support ribs 72 increase the rigidity of the support top plate 71, enabling it to withstand greater loads. The four support ribs 72 can effectively disperse the load, reducing deformation or damage caused by local stress concentration during the operation of the jack 4, thereby increasing the durability of the support top plate 71 and extending its service life. At the same time, the support top plate 71, the support side plates 73, and the support ribs 72 are arranged perpendicular to each other to form a stable frame structure, which helps to improve the stability and bending resistance of the lifting plate. The support ribs 72 can effectively disperse the load borne by the support top plate 71 and the support side plates 73, reducing local stress concentration, thereby preventing the geometric shape of the structure.

[0043] refer to Figure 1 、 2Specifically, in this embodiment, lift connecting rods 74 are provided on both sides of the lift plate 7. The lift connecting rods 74 are hingedly connected to the first connecting rod 5, and the lift connecting rod 74 of the lift plate 7 on the other side is hingedly connected to the second connecting rod 6. In actual use, the lift connecting rods 74 are hingedly connected to the first connecting rod 5 or the second connecting rod 6, so that the lift plate 7 has relative rotational freedom with the first connecting rod 5 or the second connecting rod 6, thereby allowing the lift plate 7 to be flexibly raised and lowered.

[0044] refer to Figure 1 、 2 Specifically, in this embodiment, abutting connecting rods 81 are provided on both sides of the abutting column 8. The abutting connecting rods 81 are hingedly connected to the second connecting rod 6, and the abutting connecting rod 81 of the abutting column 8 on the other side is hingedly connected to the first connecting rod 5. In actual use, the abutting connecting rods 81 are hingedly connected to the second connecting rod 6 or the first connecting rod 5, so that there is relative rotational freedom between the lifting plate 7 and the second connecting rod 6 or the first connecting rod 5, thereby allowing the abutting column 8 to be flexibly raised and lowered.

[0045] The implementation principle of a simple building jacking device in the embodiment of the present application is as follows: during construction, a pair of first connecting rods 5 and a pair of second connecting rods 6 in the first lifting platform 2 are respectively installed on both sides of the structural column 1, and the first connecting rod 5 and the second connecting rod 6 on the same side are cross-rotatably connected. After the connection, a lifting plate 7 and a tightening column 8 are respectively arranged at both ends between the two first connecting rods 5, and the position of the tightening column 8 is higher than the lifting plate 7. Correspondingly, a lifting plate 7 and a tightening column 8 are also respectively arranged at both ends between the two second connecting rods 6. The bottom of the jack 4 is placed on the lifting plate 7. When the jack 4 is in motion, the jack 4 located on the lifting plate 7 is in motion, and the top of the jack 4 is lifted and tightened. The second lifting platform 3 is located above the first lifting platform 2. At the same time, due to the action of the jack 4, the first lifting platform 2 is subjected to downward pressure, so that the first connecting rod 5 and the second connecting rod 6 are separated, so that the clamping column 8 is firmly pressed against the structural column 1. Similarly, due to the action of the jack 4, the second lifting platform 3 is subjected to upward stress. Since the first and second lifting platforms 3 have the same structure but are symmetrically installed, when the lifting plate 7 in the first lifting platform 2 is subjected to force, the clamping column 8 in the second lifting platform 3 is firmly pressed against the structural column 1. After the first lifting platform 2 and the second lifting platform 3 fix the structural column 1, the jack 4 continues to move to lift the second lifting platform 3, thereby driving the structural column 1 to be lifted.

[0046] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
