Description

Technical Field

[0001] This disclosure relates to the field of guiding device technology, and in particular to vertical limiting guiding devices and systems. Background Technology

[0002] Reverse demolition is a process of demolishing the entire building structure layer by layer, using the ground floor as the construction layer. It is a supplement to traditional demolition methods such as manual demolition, mechanical demolition, and blasting demolition. This method has a low operating area, effectively reducing noise transmission and dust diffusion during the demolition process. It is environmentally friendly and green, and is suitable for the demolition of building structures in densely populated urban areas.

[0003] Reverse demolition involves cutting off the vertical components of the existing structure to be demolished, setting up hydraulic equipment and constructing new vertical conversion components at the bottom of the building, and alternately supporting the vertical load of the structure to be demolished. In reverse demolition construction, especially during the descent of the structure, there are no guiding devices to limit the descent of the building. During the descent of the building, it is easy for vertical deviation to occur, which may lead to the building tilting and collapsing. Summary of the Invention

[0004] One of the technical problems this disclosure aims to solve is the situation where the original building structure tilts and collapses due to vertical displacement during reverse demolition.

[0005] To address the aforementioned technical problems, this disclosure provides a vertical limiting and guiding device, comprising:

[0013] In some embodiments, the aforementioned vertical limiting guide device has a limiting disc with a diameter larger than that of the positioning nut.

[0014] In some embodiments, the aforementioned vertical limiting guide device has a plurality of rotating holes distributed on the outer surface of the adjusting nut around the axial direction for cooperating with an external attachment having a connector adapted to the rotating holes to rotate the adjusting nut.

[0015] In some embodiments, the aforementioned vertical limiting guide device has a connecting plate provided along the axial direction of the limiting portion at the position where the limiting portion abuts against the moving member, so as to provide a flat moving surface for the moving member.

[0016] In some embodiments, the aforementioned vertical limiting and guiding device further includes a first base plate in the connecting portion. The first base plate is parallel to the horizontal support surface and is attached to the upper surface or surface of the floor slab and / or beam; or

[0017] The connecting portion includes a first substrate and a second substrate. The first substrate is parallel to the horizontal support surface, and the second substrate is perpendicular to the first substrate. The first substrate is attached to the upper or lower surface of the floor slab and / or beam, and the second substrate is attached to the surface of the floor slab and / or beam adjacent to the upper or lower surface and facing the limiting portion; or

[0018] The connecting part includes a first substrate, a second substrate, and a third substrate. The first substrate and the third substrate are arranged parallel to the horizontal support surface and spaced apart. The two ends of the second substrate are perpendicular to the first substrate and the third substrate, respectively. The first substrate and the third substrate are respectively attached to the upper and lower surfaces of the floor slab and the beam. The second substrate is attached to the surface of the floor slab and / or the beam that is adjacent to the upper and lower surfaces and faces the limiting part.

The moving part at one end of the connecting part makes contact with the limiting part. During the process of descending the building through reverse demolition, the moving part and the limiting part make contact and cooperate to achieve a stable descent of the building without deviation, thereby avoiding the building tilting and collapse.

[0041] Example 1

[0042] Reference Appendix Figure 1 This embodiment discloses a vertical limiting and guiding device, which includes: a limiting part 1 and several connecting parts 2; the limiting part 1 is disposed on a horizontal support surface inside the room to be demolished, the limiting part 1 extends in the opposite direction of gravity and penetrates the reserved hole 3 of the floor slab 4 in the room to be demolished; several connecting parts 2 are evenly distributed around the axial direction of the limiting part 1, the connecting parts 2 are arranged radially along the reserved hole 3, one end is detachably connected to the floor slab 4 and / or the beam 13, and the other end is provided with a moving part 5 to move against the surface of the limiting part 1.

[0043] Specifically, to address the issue of unstable descent and potential vertical deviation during existing reverse demolition processes, this embodiment provides a vertical limiting and guiding device. First, pre-drilled holes 3 are made in the floor slab 4 inside the room to be demolished. The location and number of these holes can be adapted to the specific structure of the room. Then, a limiting part 1 is positioned on the horizontal support surface of the room to be demolished, passing through the pre-drilled holes 3. This horizontal support surface can be the ground or a floor slab 4 inside the room that does not need to be demolished. Simultaneously, one end of the connecting part 2 is detachably connected to the floor slab 4 and / or beam 13 around the limiting part 1, which can be, but is not limited to, a threaded connection. The moving part 5 at the other end of the connecting part 2 abuts against the limiting part 1. After all the structures below the floor slab 4 and / or beam 13 are demolished, the moving part 5 moves to the designated position of the limiting part 1 as the floor slab 4 and / or beam 13 descends, thus determining the specific position of the floor slab 4 and / or beam 13 and effectively preventing the building from shifting.

[0044] The vertical limiting guide device provided in this embodiment is used in reverse demolition engineering. In reverse demolition engineering, the original bottom support components of the building are removed one by one and replaced with external hydraulic devices. Then, all structures are removed one by one from the bottom of the building upwards. At the same time, the hydraulic devices can be controlled by an external controller to lower synchronously, and finally the building is demolished.

[0045] Among them, the limiting part 1 is a rigid column with a certain height. The specific height can be adjusted according to the height of the building and the height of the floor slab 4 to be demolished. Its interior can be solid or hollow, as long as it is installed stably on the horizontal support surface.

[0046] The connecting part 2 can be a rigid plate or frame structure, and can be an integral structure or a combination of multiple structural components. It is used to connect the floor slabs 4 and / or beams 13 to be demolished. The connection method can be screwed, snap-fitted, welded, glued, etc., and can be adapted to the specific building structure. It is sufficient to ensure that all the floor slabs 4 and / or beams 13 to be demolished can be moved as a whole.

[0047] The moving part 5 can be a slider or a roller to move against the limiting part 1. When the floor slab 4 and / or beam 13 to be demolished descends, the moving part 5 can descend against the limiting part 1 to play a guiding role.

[0048] As described above, the vertical limiting and guiding device provided in this disclosure, during the descent of the floor slab 4 and / or beam 13 to be demolished, uses a limiting part 1 set inside the supporting surface of the building to be demolished. The limiting part 1 penetrates the pre-drilled hole 3 in the floor slab 4 within the building. Subsequently, under the action of several connecting parts 2 and corresponding moving parts 5, the floor slab 4 and / or beam 13 to be demolished moves axially along the limiting part 1, ensuring that the floor slab 4 and / or beam 13 remains vertically downward during movement, preventing vertical deviation and ensuring the smooth descent of the floor slab 4 and / or beam 13 without causing the building to tilt or collapse.

[0049] In this article, the term "and / or" is merely a description of the relationship between related objects, identifying three possible relationships, such as A and / or B. Specifically, it can be understood as: A and B can be included simultaneously, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0050] In some embodiments, refer to the appendix Figure 1 In the vertical limiting guide device provided in this embodiment, the moving part 5 can slide or roll along the axial direction of the limiting part 1.

[0051] Specifically, in order to facilitate the better movement of the floor slab 4 and / or beam 13 to be demolished, the moving part 5 in this embodiment can be a roller or other sliding part to achieve sliding or rolling engagement between the moving part 5 and the limiting part 1. The sliding engagement makes the downward movement of the floor slab 4 and / or beam 13 to be demolished smoother; the rolling engagement can further reduce friction, and will not cause the floor slab 4 and / or beam 13 to be demolished to be unable to fall normally due to high friction, which is conducive to the smooth progress of the demolition work.

[0052] In some embodiments, refer to the appendix Figure 2 In the vertical limiting guide device provided in this embodiment, the moving part 5 is movably disposed with the connecting part 2 along the first direction a, and the moving part 5 can move away from or closer to the limiting part 1 along the first direction a; wherein, the first direction a is the direction in which the connecting part 2 points to the moving part 5.

[0053] Specifically, in order to adapt to floor slabs 4 of different sizes, in this embodiment, the moving part 5 can move in the first direction a, which is the direction in which the connecting part 2 points to the moving part 5. That is, when the connecting part 2 is connected to the floor slab 4 to be demolished, and the moving part 5 cannot contact the limiting part 1, the moving part 5 can be moved along the first direction a until it contacts the designated area of ​​the limiting part 1. In this way, when the floor slab 4 to be demolished falls, it can achieve directional guidance and avoid vertical deviation.

[0054] In some embodiments, refer to the appendix Figure 2 and attached Figure 9 In this embodiment, the vertical limiting guide device includes a connecting part 2 including a connecting box 204. An auxiliary component 6 is slidably connected inside the connecting box 204 towards the limiting part 1. The auxiliary component 6 is connected to the moving part 5. A limiting plate 7 is provided on the side of the auxiliary component 6 away from the limiting part 1. The axis of the limiting plate 7 is perpendicular to the direction of gravity. The limiting plate 7 has a notch 8 in the radial direction. A limiting pin 9 extends inside the connecting box 204 along the first direction a. The notch 8 is engaged with the limiting pin 9.

[0055] Specifically, to prevent the moving part 5 from rotating axially, the moving part 5 is connected to the auxiliary part 6 located inside the connecting box 204. The rotation of the moving part 5 is restricted by the engagement of the limiting plate 7 at one end of the auxiliary part 6 with the limiting pin 9 inside the connecting box 204, thus preventing the moving part 5 from rotating and avoiding any deviation in the direction of movement. The limiting plate 7 is located inside the connecting box 204 and is located away from the limiting part 1. The limiting plate 7 has a radial notch 8, which engages with the limiting pin 9. The extension direction of the limiting pin 9 is the same as the extension direction of the auxiliary part 6, both pointing towards the corresponding limiting part 1. When the moving part 5 adjusts the distance it extends out of the connecting box 204, the notch 8 on the surface of the limiting plate 7 also moves on the surface of the limiting pin 9, thus ensuring that the floor slab 4 to be demolished can descend stably along the direction of gravity when it moves through the moving part 5, without any deviation.

[0056] In some embodiments, refer to the appendix Figure 3 In this embodiment, the vertical limiting guide device includes an auxiliary component 6, which includes a first screw 601. Two sets of positioning components 10 are sleeved on the first screw 601, one set located inside the connecting housing 204 and the other set located outside the connecting housing 204. The positioning component 10 includes an adjusting nut 1001 and a positioning nut 1002. The adjusting nut 1001 is threadedly connected to the first screw 601, and the positioning nut 1002 is fixedly connected to the first screw 601.

[0057] Specifically, to ensure a stable fit between the moving part 5 and the limiting part 1, two sets of positioning components 10 are sleeved on the first screw 601 in this embodiment, located inside and outside the connecting housing 204 respectively. When the moving part 5 moves to the position of fitting the limiting part 1, the two sets of positioning components 10 can fix the specific position of the moving part 5. At the same time, the positioning component 10 includes an adjusting nut 1001 and a positioning nut 1002. The adjusting nut 1001 is threadedly connected to the first screw 601. After the specific position of the moving part 5 is determined, rotating the two adjusting nuts 1001 can fix the first screw 601 to the connecting housing 204, thereby limiting the specific position of the moving part 5. The positioning nut 1002 is fixedly connected to the first screw 601, which can determine the specific range of movement of the first screw 601 and the moving part 5, and prevent the first screw 601 and the moving part 5 from detaching from the connecting housing 204.

[0058] In some embodiments, refer to the appendix Figure 4 In this embodiment, the vertical limiting guide device has a diameter of 7 that is larger than the diameter of 1002.

[0059] Specifically, in order to facilitate better movement of the moving part 5, the diameter of the limiting plate 7 is larger than the diameter of the positioning nut 1002 in this embodiment. When the moving part 5 moves and drives the first screw 601 to move, it drives the limiting plate 7 to slide and connect with the limiting pin 9. At this time, the fixing nut will not contact the limiting pin 9, thus facilitating better movement of the moving part 5.

[0060] In some embodiments, refer to the appendix Figure 4 In the vertical limiting guide device provided in this embodiment, in a specific implementation, the adjusting nut 1001 has a plurality of rotating insertion holes 11 distributed on its outer surface around the axial direction, which are used to cooperate with an external attachment having a plug fitting adapted to the rotating insertion holes 11 to rotate the adjusting nut 1001.

[0061] Specifically, to facilitate the rotation of the adjusting nut 1001, this embodiment provides several rotating insertion holes 11 around the axial direction of the adjusting nut 1001. Since the diameter of the adjusting nut 1001 is too large, a traditional wrench cannot directly act on the adjusting nut 1001 to achieve rotation and adjustment. Therefore, an external connector adapted to the rotating insertion holes 11 is needed to rotate the adjusting nut 1001. The external connector can be a steel bar or steel pipe that matches the diameter of the rotating insertion holes 11, which can extend the lever arm acting on the adjusting nut 1001. By rotating the external connector, the adjusting nut 1001 can be driven to rotate.

[0062] In some embodiments, refer to the appendix Figure 5In the vertical limiting guide device provided in this embodiment, in specific implementation, a connecting plate 12 is provided along the axial direction of the limiting part 1 at the position where the limiting part 1 abuts against the moving part 5, so as to provide a flat moving surface for the moving part 5.

[0063] Specifically, when the moving part 5 moves at the designated position of the limiting part 1, the limiting part 1 cannot guarantee that the surface of the position that abuts the moving part 5 is sufficiently flat after a long period of use. As a result, the moving part 5 cannot move downward stably when it moves at this position. Therefore, by setting a connecting plate 12 at the position of abutment, wherein the connecting plate 12 is a plate with a flat surface, which can be a steel plate or iron plate that fits against the limiting part 1, the position of abutment can be guaranteed to be a flat moving surface, thereby facilitating better movement of the moving part 5.

[0064] In some embodiments, refer to the appendix Figure 6 Appendix Figure 7 and attached Figure 8 In this embodiment, the vertical limiting and guiding device further includes a first base plate 201 in the connecting part 2. The first base plate 201 is parallel to the horizontal support surface and is attached to the upper surface or surface of the floor slab 4 and / or the beam 13; or

[0065] The connecting portion 2 includes a first substrate 201 and a second substrate 202. The first substrate 201 is parallel to the horizontal support surface, and the second substrate 202 is perpendicular to the first substrate 201. The first substrate 201 is attached to the upper or lower surface of the floor slab 4 and / or the beam 13, and the second substrate 202 is attached to the surface of the floor slab 4 and / or the beam 13 adjacent to the upper or lower surface and facing the limiting portion 1; or

[0066] The connecting part 2 includes a first substrate 201, a second substrate 202 and a third substrate 203. The first substrate 201 and the third substrate 203 are arranged parallel to the horizontal support surface and spaced apart. The two ends of the second substrate 202 are perpendicular to the first substrate 201 and the third substrate 203, respectively. The first substrate 201 and the third substrate 203 are respectively attached to the upper and lower surfaces of the floor slab 4 and the beam 13. The second substrate 202 is attached to the surface of the floor slab 4 and the beam 13 that is adjacent to the upper and lower surfaces and faces the limiting part 1.

[0067] Specifically, typically, a single floor includes multiple floor slabs 4 and beams 13, with the lower surface of the floor slabs 4 fixedly connected to the beams 13 around its perimeter. In this embodiment, to facilitate better installation of the connecting part 2 with the floor slabs 4 and / or beams 13, the connecting part 2 can be installed with the floor slabs 4 and / or beams 13 in three ways. In the first case, the connecting part 2 includes a first base plate 201, which is directly attached to the upper or lower surface of the floor slabs 4 and / or beams 13 and detachably connected to the floor slabs 4, thus determining the specific location of the connecting part 2. In the second case, the connecting part 2 includes a first base plate 201 and a second base plate 202, where the first base plate 201 is attached to the upper or lower surface of the floor slabs 4 and / or beams 13 and detachably connected to the floor slabs 4, and the second base plate 202 is vertical. In the first substrate 201, the second substrate 202 is attached to the floor slab 4 and / or the beam 13 adjacent to the upper or lower surface and is used facing the corresponding limiting part 1, so that the moving part 5 can abut against the limiting part 1; in the third case, the connecting part 2 includes the first substrate 201, the second substrate 202 and the third substrate 203, wherein the first substrate 201 and the third substrate 203 are attached to the upper and lower surfaces of the floor slab 4 and the beam 13 respectively, the second substrate 202 is connected to and perpendicular to the first substrate 201 and the third substrate 203, and is used facing the corresponding limiting part 1. Through the above three cases, the connecting part 2 is detachably connected to the floor slab 4, and finally, the moving part 5 abuts against the limiting part 1 to realize the directional descent of the floor slab 4 and avoid the tilting of the building. It is understandable that when the size of the reserved hole 3 is large, the edge of the hole is close to the crossbeam 13, and the connecting part 2 can be directly connected to the crossbeam 13. When the size of the reserved hole 3 is small, the edge of the hole is still the floor slab 4, and the connecting part can be directly connected to the floor slab 4.
