Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a structure for building lifting and lowering. Background Technology

[0002] In the process of urban renewal and development, there are a large number of existing buildings that need maintenance and repair. When a building tilts due to uneven settlement, or when a building needs to be moved or an underground floor needs to be added due to planning adjustments, it may involve lifting the building.

[0003] Traditional jacking methods involve installing corbels on both sides of the building's vertical structural members, placing jacks and support blocks beneath the corbels, then cutting off the structural walls and columns, using the support blocks for temporary support, and finally lifting the building to the designed height using jacks. This method has the following drawbacks:

[0004] 1) The lifting height of the building is limited by the stroke of the jack. When the jack completes one stroke to replace the top, it is necessary to use pads or other temporary support structures.

[0005] 2) When replacing the jack, the installation of temporary supports such as pads requires a lot of manpower, which is cumbersome and has low construction efficiency.

[0006] 3) Temporary support components such as pad blocks are usually stacked to increase height, resulting in an unstable structure and unavoidable errors. These require real-time manual adjustments, making construction cumbersome. If the errors at different points are too large during the jacking process, it will be detrimental to structural safety and pose a high construction risk.

[0007] To address the aforementioned issues, this utility model provides a structure for building lifting and lowering. This structure utilizes a reaction platform and a support column as support points, and the lifting height is not limited by the stroke of the jacks, eliminating the need for separate temporary supports such as pads. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of the existing technology by providing a structure for lifting and lowering buildings. This device eliminates the need for temporary supports such as pads, and the lifting height is not limited by the stroke of the jacks. During the lifting process, the jacks can be replaced as needed, and the supporting columns can be lengthened and heightened. The construction process requires minimal manual labor, is simple and efficient, and offers a high degree of safety.

[0009] A structure for lifting and lowering a building includes a support column 7, a jack 8, a reaction beam 9, an anchor 10, and tie rods 13. The lower end of the support column 7 is supported by a reaction platform 3 and passes upward through a reserved hole a6 in the support beam 5. The jack 8 is provided at the upper end of part or all of the support column 7, and the upper end of the jack 8 can apply upward force to the reaction beam 9. The lower end of a set of tie rods 13 is fixedly connected to the support beam 5, and the upper end passes through a reserved hole b in the reaction beam 9 and is fixedly connected to the anchor 10 above the reaction beam 9.

[0010] This structure, used for building lifting and lowering, requires no temporary supports such as pads, and the lifting height is not limited by the jack stroke. During the lifting process, jacks can be replaced as needed, and the supporting columns can be lengthened and heightened. The construction process requires minimal manpower, is simple and efficient, and offers a high degree of safety.

[0011] Preferably, the pull rods 13 are symmetrically arranged on both sides of the support column 7.

[0012] Furthermore, a set of tie rods 13, a support column 7, a jack 8, a reaction beam 9, and an anchor 10 constitute a lifting functional unit; a set of tie rods 13, a support column 7, a reaction beam 9, and an anchor constitute a locking functional unit; at least one of the aforementioned lifting functional units is correspondingly provided on a single reaction platform 3.

[0013] Furthermore, the anchor 10 is a nut, clamp, or jack.

[0014] Furthermore, each reaction platform 3 corresponds to several locking functional units. Through the lifting of the jacks 8 in the lifting functional unit, and in conjunction with the locking of the anchors 10, the beam 5 and the building 1 are gradually lifted upward.

[0015] Furthermore, a single reaction platform 3 corresponds to multiple lifting functional units, and multiple jacks 8 alternately lift to gradually raise the supporting beam slab 5 and the building 1.

[0016] Furthermore, the lifting structure composed of the locking function unit and the lifting function unit is divided into two groups, A and B, which work independently and collaboratively. When both the locking function unit and the lifting function unit are present, the lifting function unit is located in group A and the locking function unit is located in group B.

[0017] Furthermore, Group B can be evenly distributed on both sides of Group A, or Group B can be evenly distributed around Group A.

[0018] Furthermore, groups A and B successively form a ring.

[0019] The beneficial effects of this utility model are:

[0020] 1) This device only requires equipment such as support columns, jacks, reaction beams, anchors and tie rods, without the need for temporary supports such as pads, and requires no large amount of manpower.

[0021] 2) Using Group A and Group B lifting structures in tandem to lift the building effectively reduces the risks associated with unexpected situations such as jack failure during the lifting process. By locking the anchors on the reaction beams of Group A and Group B in groups, the jacks on the upper part of the support columns can be replaced in groups, or the support columns of Group A or Group B can be extended in groups. The lifting height of the building is not limited by the stroke of the jacks.

[0022] 3) During the jacking construction process, in case of unexpected situations or extreme weather, the building can be quickly lowered back to the reaction platform at any time without having to remove temporary supports such as pads layer by layer, which ensures a high degree of safety.

[0033] Implementation, for example Figure 1 As shown in Figure 3, a structure for lifting and lowering a building includes a support column 7, a jack 8, a reaction beam 9, an anchor 10, and a tie rod 13.

[0034] See Figure 2 and Figure 3 The lower end of the support column 7 is supported by the reaction platform 3 and passes upward through the reserved hole a6 of the support beam plate 5. The upper end of part or all of the support columns 7 is provided with the jack 8, and the upper end of the jack 8 can apply upward force to the reaction beam 9. The lower end of a set of tie rods 13 is connected to the anchor rod 11 on the support beam plate 5 through the sleeve 12, and the upper end passes through the reserved hole b (not shown in the figure) of the reaction beam 9 and is fixedly connected to the anchor 10 located on the reaction beam 9.

[0035] The following description will further illustrate the characteristics and functions of this utility model.

[0036] In the specific implementation of this embodiment:

[0037] like Figure 2As shown, a reaction platform 3, a wall-clamping beam 4, and a replacement beam slab 5 are constructed around the vertical structure of building 1. The reaction platform 3 serves as the installation platform for the jacking structure and the operating platform for the jacking construction. The wall-clamping beam 4 is located on both sides of the vertical structure of building 1 and is fixedly connected to the vertical structure of building 1. The replacement beam slab 5 is fixedly connected to the wall-clamping beam 4. Anchor rods 11 are pre-embedded on the replacement beam slab 5, and the anchor rods 11 can be rebar installed later. To ensure the fixed connection between the wall-clamping beam 4 and the replacement beam slab 5, steel bars can be pre-reserved at the overlap position of the wall-clamping beam 4 and the replacement beam slab 5, or they can be connected by rebar installation. The replacement beam slab 5 has pre-reserved holes 6 around the replacement column 7 to ensure that the replacement beam slab 5 and the replacement column 7 are not connected and can move up and down relative to each other.

[0038] The support column 7 is fixedly connected to the reaction platform 3. Pre-embedded parts (not shown in the attached diagram) can be installed on the upper part of the reaction platform 3 beforehand. After the reaction platform 3 reaches its design strength, the support column 7 is fixedly connected to the pre-embedded parts by welding or mechanical connection. Alternatively, the support column 7 can be directly cast as a single unit with the reaction platform 3 during its pouring. The support column 7 can be a steel column, structural steel, concrete component, etc. If a steel column is used, concrete can be poured inside the support column 7 to improve its strength and load-bearing capacity.

[0039] The reaction platform 3 can be made of steel plates, precast concrete components, etc. If the site conditions permit, the hard ground around building 1 can be used directly as the reaction platform 3.

[0040] like Figure 3 As shown, when the building load is large or the foundation soil is weak, and the foundation below the reaction platform 3 cannot provide sufficient bearing capacity, foundation treatment can be carried out, or replacement piles can be installed. The replacement piles 14 can be bored piles or precast piles. Due to the small indoor space, the replacement piles distributed indoors can be implemented in sections using low-headroom miniaturized equipment, and the upper and lower sections can be connected by welding or mechanical connection.

[0041] The lifting structure is divided into two types: lifting functional unit and locking functional unit, among which:

[0042] A set of tie rods 13, a support column 7, a jack 8, a reaction beam 9, and an anchor 10 constitute a lifting functional unit;

[0043] A set of tie rods 13, a support column 7, a reaction beam 9, and an anchor 10 constitute a locking functional unit; at least one of the aforementioned locking functional units is correspondingly provided on a single reaction platform 3.

[0044] In the first and second embodiments, as Figure 4 and Figure 5 As shown, the lifting structures corresponding to the same reaction platform 3 include group A and group B.

[0045] Group A consists entirely of lifting function units, which include one or more support columns, with one jack installed on the top of each support column.

[0046] Group B contains one or more locking function units, which may also contain lifting function units, i.e., one or more support columns 7, with jacks 8 installed on the top of the support columns 7 as needed.

[0047] When group A consists of one support column and group B contains two or more support columns, the support columns of group B are evenly distributed around the support columns of group A. Figure 4 and 5 As shown. The number and arrangement of the lifting structure and the A and B groups of supporting columns included in each lifting structure can be comprehensively considered based on factors such as the load distribution characteristics of building 1, the form and arrangement of the reaction platform 3 and the supporting beam slab 5, to ensure that building 1 can be uniformly stressed and smoothly lifted and lowered.

[0048] In the third embodiment, when group A contains one replacement column and group B also contains one replacement column, such as Figure 6 As shown.

[0049] In the fourth embodiment, when group A contains two support columns and group B also contains two support columns, groups A and B are arranged uniformly and symmetrically, such as... Figure 7 As shown.

[0050] Specifically, jack 8 is located on support column 7, reaction beam 9 is located on jack 8, and tie rods 13 are symmetrically distributed on both sides or around jack 8. The lower part of tie rod 13 is connected to anchor rod 11 through sleeve 12, and the upper part of tie rod 13 is connected to anchor 10. Tie rod 13 passes through holes in reaction beam 12. Anchor 13 can be nuts, clamps, or through-hole jacks, etc.

[0051] In the first embodiment, in conjunction with the appendix Figure 8 When preparing for jacking, the anchor 10 on the reaction beam 9 of group A is locked. The reaction beam 9 transmits the jacking force of the jack 8 to the anchor 10, and then to the tie rod 13. The tie rod 13 drives the supporting beam 5 and the building 1 to rise. When the jack 8 of group A completes one stroke, the anchor 10 on the reaction beam 9 of group B is locked, the jack 8 of group A retracts, and the reaction beam 9 falls back. Since the reaction beam 9 of group B and the tie rod 13 are locked by the anchor 10, the supporting beam 5 is locked by the tie rod 13 of group B, thus limiting the fall of the supporting beam 5 and the building 1. The jack 8 of group A retracts, and the reaction beam 9 falls back to its position. The anchor 10 on the reaction beam 9 of group A is locked, and the next stroke begins.

[0052] In the second embodiment, in conjunction with the appendix Figure 9When Group B is also equipped with jack 8, after Group A completes one stroke, the anchor 10 on the reaction beam 9 of Group B is locked, and the jack 8 of Group B is lifted. The reaction beam 9 transmits the lifting force of the jack 8 to the anchor 10, and the anchor 10 transmits the lifting force to the tie rod 13. The tie rod 13 will lift the supporting beam 5 and the building 1. When the jack 8 of Group A retracts, the reaction beam 9 falls back simultaneously, and the anchor 10 on the reaction beam 9 of Group A is locked. The alternating locking and lifting of Group A and Group B can realize the relay lifting of the building 1.

[0053] By coordinating the lifting structures of Group A and Group B, Building 1 can be raised to its designed height. Conversely, it can be lowered back down.

[0054] If building 1 already has a local tilt before being lifted, differentiated lifting can be used to increase the lifting amount in the large settlement area, thereby achieving the purpose of correcting the tilt of building 1.

[0055] After the building is lifted into place, foundation reinforcement and connections can be carried out as needed to meet subsequent use requirements.

[0056] Furthermore, when the building needs to be moved, a track beam is laid under the wall beam, part of the supporting beam is removed, and the remaining supporting beam and wall beam are converted into an upper sliding beam. A sliding device is installed between the upper sliding beam and the track beam to prepare for the building's movement. If a flatbed trailer is used for the movement, after the lifting is completed, the building and supporting beam can be directly lowered back onto the flatbed trailer.

[0057] Furthermore, when it is necessary to add underground floors below the building, the building is lifted and lowered according to construction needs, earthwork is excavated and underground structures are constructed below the building, and after the underground structure is completed, the building is lowered back onto the newly built underground structure slab below the building.

[0058] Although the concept and embodiments of the present invention have been described in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can be made to the present invention without departing from the scope of the claims. These modifications may involve variations in the type, material, quantity, arrangement, spacing, and dimensions of buildings, foundations, underpinning piles, reaction platforms, wall beams, underpinning beams / slabs, underpinning columns, tie rods, jacks, reaction beams, anchors, etc. Therefore, these variations will not be elaborated upon here. Those skilled in the art can make their own modifications or improvements based on this, and all such modifications or improvements should fall within the scope of protection claimed by the present invention without departing from the overall concept of the invention.
