Description

Technical Field

[0001] This invention relates to the field of construction machinery, specifically to a temporary support limiting device and construction method for dismantling horizontal structures. Background Technology

[0002] Currently, static cutting methods such as chainsaws are commonly used to demolish horizontal structures on construction sites. Before demolition, temporary support devices must be installed beneath the structure. However, site conditions vary, and not all areas are suitable for setting up supports. Furthermore, the type of support structure is limited by site conditions and structural height. Even when temporary supports are feasible, they occupy significant space and area, generally only providing vertical support and failing to effectively guarantee lateral stability, posing significant safety risks and making construction extremely inconvenient. For the demolition of taller or heavier structures, conventional support systems are insufficient, and the load-bearing capacity of the underlying structure cannot be adequately supported. Moreover, the use of upper suspended support systems is also limited by construction conditions, such as: no overhead suspension, insufficient load-bearing capacity of the suspended structure, or stability issues due to significant height differences. Summary of the Invention

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] A temporary support and limiting device for the demolition of a horizontal structure includes a fixed support, a connecting mechanism, and a support limiting mechanism. The fixed support is connected to the surrounding structure of the structure to be demolished in the horizontal structure. The support limiting mechanism is fixed on the structure to be demolished. The fixed support is fixedly connected to the support limiting mechanism through the connecting mechanism, which includes several connecting parts.

[0006] As a preferred technical solution, the fixed support includes several fixed components that are assembled at equal intervals along the length direction of the horizontal structure.

[0007] As a preferred technical solution, the fixing component of the fixed support includes two fixing parts and one reinforcing part. The two fixing parts are arranged on both sides of the horizontal structure. The bottom of the two fixing parts is fixedly connected by a connector. The top of the two fixing parts is connected to both ends of the reinforcing part and limited by two sets of connectors.

[0008] As a preferred technical solution, the support and limiting mechanism is the same as the fixed support except that the top of the fixed component is not equipped with reinforcement parts and two sets of connecting parts for limiting when hoisting the structure to be dismantled.

[0009] As a preferred technical solution, the fastener includes a cross-shaped component and a vertical bar. The bottom end of the vertical bar is fixed at the center of the cross-shaped component. The two adjacent ends of the cross-shaped component are provided with slots, and the other two ends of the cross-shaped component are provided with inserts. The slots and inserts match. The four ends of the cross-shaped component are provided with equally spaced circular holes. Two adjacent cross-shaped components and two corresponding cross-shaped components on both sides of the horizontal structure are connected by a connector, which passes through the circular holes.

[0010] As a preferred technical solution, the top of the vertical bar is provided with a number of equally spaced slots, the reinforcing member is strip-shaped, and the two ends of the reinforcing member pass through the slots of the vertical bar on both sides of the horizontal structure. The two ends of the reinforcing member are provided with through holes arranged at equal intervals along the width direction of the reinforcing member. The two sets of connecting members with top limit in the fixing component pass through the through holes on both sides of the reinforcing member, so that the side of the vertical bar abuts against the horizontal structure.

[0015] Step two: Cut the horizontal structure;

[0016] Step 3: Open the top of the support and limiting mechanism, and lift and dismantle the structure to be removed from the horizontal structure.

[0017] Step 4: Remove the fixed support and the supporting limit mechanism.

[0028] The technical solution of the present invention will be further described below with reference to specific embodiments:

[0029] like Figure 1As shown, a temporary support and limiting device for dismantling a horizontal structure 4 includes a fixed support, a connecting mechanism, and a support limiting mechanism. The fixed support is connected to the peripheral structure 42 of the structure 41 to be dismantled in the horizontal structure 4. The width and height of the fixed support can be adjusted according to the structural conditions of the horizontal structure 4. The support limiting mechanism is fixed on the structure to be dismantled. The fixed support is fixedly connected to the support limiting mechanism through the connecting mechanism. The connecting mechanism includes several connecting parts 3 for effective connection and fixation of the fixed support and the support limiting mechanism.

[0030] like Figure 4 As shown, the fixed support includes several fixed components assembled at equal intervals along the length of the horizontal structure 4. The number of fixed components can be adjusted as required to meet the load requirements of different horizontal structures 4. The connection positions of the fixed components can be marked with certain dimensions to facilitate splicing according to the dimensions of the horizontal structure 4.

[0031] like Figure 2 and Figure 5 As shown, the fixing component of the fixed support includes two fixing parts 1 and one reinforcing part 2. The two fixing parts 1 are arranged on both sides of the horizontal structure 4. The bottom of the two fixing parts 1 is fixedly connected by a connector 3. The top of the two fixing parts 1 is connected to both ends of the reinforcing part 2 and limited by two sets of connectors 3.

[0032] like Figure 3 As shown, the support limiting mechanism is the same as the fixed support except that the top of the fixed component is not equipped with the reinforcement 2 and the two sets of limiting connectors 3 when the structure 41 to be dismantled is hoisted.

[0033] The fastener 1 includes a cross-shaped component 11 and a vertical bar 12, with the bottom end of the vertical bar 12 fixed at the center of the cross-shaped component 11, such as... Figure 6 As shown, the two adjacent ends of the cross member 11 are provided with slots, and the other two ends of the cross member 11 are provided with inserts. The slots and inserts match. The four ends of the cross member 11 are provided with equally spaced round holes. The two adjacent cross members 11 and the two cross members 11 on both sides of the horizontal structure 4 are connected by inserts into the slots, and are fixed and limited by the connector 3 passing through the round holes.

[0034] The top of the vertical strip 12 has several equally spaced slots. The reinforcing member 2 is strip-shaped, with both ends passing through the slots of the vertical strip 12 on both sides of the horizontal structure 4. The ends of the reinforcing member 2 have equally spaced perforations along its width. In the fixing assembly, each of the two sets of top-limiting connectors 3 has two connectors, and the four connectors 3 pass through the perforations on both sides of the reinforcing member 2, causing the sides of the vertical strip 12 to abut against the horizontal structure 4. The height of the vertical strip 12 can be adjusted and limited through the multiple slots, and the two sets of top-limiting connectors 3 in the fixing assembly can limit the horizontal position of the two vertical strips 12.

[0035] like Figure 5 As shown, the bottom surface of the reinforcement 2 and the side of the vertical bar 12 near the horizontal structure 4 are provided with limiting pads 21. The limiting pads 21 fit against the horizontal structure 4 to prevent damage to the horizontal structure 4.

[0036] like Figure 7 As shown, the connector 3 includes a bolt 31 and a nut 32. The inner ring of the nut 32 has a thread that matches the bolt 31, and a limit sensor is provided at the bottom of the bolt 31. The connector 3 can also adopt other pin-type structures. The limit sensor includes a pressure sensor and a displacement sensor, which can transmit information such as pressure and displacement, and then summarize the stress and deformation of the horizontal structure 4.

[0037] like Figure 1 and Figure 2 As shown, a construction method for removing the temporary support limiting device of a horizontal structure 4 includes the following steps:

[0038] Step 1: Before the demolition work, install the fixed support on the peripheral structure 42 of the structure 41 to be demolished in the horizontal structure 4, install the support limiting mechanism on the structure 41 to be demolished in the horizontal structure 4, and fix it with the connector 3.

[0039] Step 2: Cut the horizontal structure 4;

[0040] Step 3: Remove the reinforcing member 2 and the connecting parts 3 at both ends of the reinforcing member 2 from the fixing component of the supporting limiting mechanism, and lift and remove the structure 41 to be removed from the horizontal structure 4.

[0041] Step four: Remove the fixed supports and support limiting mechanisms, and repeat the construction process for the remaining working conditions.

[0042] Throughout the construction process, the impact on the upper and lower parts of the structure is minimal, and it is highly adaptable to on-site construction. The components of this device can be categorized by specifications and dimensions according to actual needs, and connected using standard parts in a specific manner to achieve the above functions. Furthermore, based on the aforementioned device principle, vertical positioning can also be achieved for vertical structures.

[0043] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-inventive modifications to this embodiment as needed after reading this specification, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
