Description

Technical Field

[0001] The invention relates to the technical field of turning over precast concrete components, in particular to a turning tool for precast concrete components. Background Art

[0002] Precast concrete components refer to concrete components that are prefabricated in a factory and transported to the construction site for assembly. Precast concrete components commonly used for building walls are generally long strip components with a fixed cross-section, one part of which is a concrete wall and the other part is an insulation wall, and the surface area of ​​the insulation wall is larger than that of the concrete wall. In the process of transporting and turning over precast concrete components for building walls, cranes are usually used to transport and turn over the precast concrete components;

[0003] However, since the surface area of ​​the insulation wall of the precast concrete component is larger than the surface area of ​​the concrete wall, when the horizontally placed concrete component is turned over, in order to prevent the edge of the insulation wall from directly touching the ground, it is usually necessary to pad stones under the edge of the precast concrete component that touches the ground, and use the height of the stones to make up for the distance that the concrete wall is shorter than the insulation wall. However, this method of using stones to pad the precast concrete component is prone to relative sliding between the precast concrete component and the stone during the turning process, causing the precast concrete component to slide off the upper end of the stone and cause damage;

[0004] In addition, the use of stones can provide a one-time support for the bottom of the precast concrete component. When the precast concrete component is subsequently assembled, the stones need to be used for support again. After each support, the stones need to be taken out from the bottom of the precast concrete component, which is cumbersome.

[0005] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0006] The purpose of the present invention is to provide a precast concrete component turning tool to solve the problems in the prior art proposed in the above-mentioned background technology that when the precast concrete component is turned over, stones are used to pad the lower end of the concrete wall. During the turning process of the precast concrete component, relative sliding between the concrete wall and the stones is likely to occur, causing the precast concrete component to slide off the upper end of the stones, and the stone support needs to be taken out from the bottom of the concrete wall after each turning, which is cumbersome.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-6 , the present invention provides a technical solution:

[0040] The precast concrete component turning tool comprises a concrete wall 11 placed on the upper part of a foundation 100, one end of the concrete wall 11 is fixedly connected to a heat preservation board 12, a support beam 101 is provided on the upper end of the foundation 100, and further comprises:

[0041] The prefabricated component unit 1 comprises an embedding mechanism 15 with one end fixedly inserted into the concrete wall 11 for limiting the position of the concrete wall 11;

[0042] The flip unit 2 includes a flip support assembly 22 disposed outside the embedding mechanism 15 for flipping and supporting the concrete wall 11 , and a fastening assembly 21 disposed on one side of the flip support assembly 22 for fastening the flipped concrete wall 11 to one side of the support beam 101 .

[0043] It should be noted that: when the concrete wall 11 is cast, one end of the embedding mechanism 15 is located inside the concrete wall 11. Before the concrete wall 11 is erected and flipped, the flip support assembly 22 is sleeved on the outside of the embedding mechanism 15, and the flip support assembly 22 and the embedding mechanism 15 are fastened together. Then, the concrete wall 11 is lifted and flipped by a crane. In this process, the flip support assembly 22 is first pressed against the ground instead of the insulation board 12, and the flip support assembly 22 is fastened to the bottom of the concrete wall 11, so that the flip support assembly 22 will not slide relative to the concrete wall 11, and the risk of the concrete precast component sliding and breaking can be avoided during the flipping of the concrete wall 11.

[0044] In addition, after the precast concrete component is flipped to the upright state, the flip support assembly 22 of the present invention can be directly supported on the foundation 100 as a base of the precast concrete component without being taken out from under the concrete wall 11.

[0045] As an improvement, Figure 3 , Figure 5 As shown, the embedding mechanism 15 includes:

[0046] An embedding rod 151 is fixedly inserted into one side of the concrete wall 11, and the inside of the embedding rod 151 is hollow;

[0047] The mounting hole 1511 is provided at the lower outer side of the embedding rod 151;

[0048] A fastening rod 152, which is fixedly sleeved on the outer side of the embedding rod 151, and a second threaded hole 1521 is respectively opened near both ends of the fastening rod 152;

[0049] The fastening bolt 153 is threadedly connected to the second threaded hole 1521 after passing through the flip support assembly 22 , and is used to fasten the fastening rod 152 and the flip support assembly 22 .

[0050] Further, such as Figure 3-4 As shown, the flip support assembly 22 includes:

[0051] A support seat 221 is provided at one end of the concrete wall 11 located at the embedding rod 151, and is used to support the concrete wall 11 during the flipping process. A first insertion hole 2211 is provided inside the support seat 221 for penetrating the embedding rod 151;

[0052] The second insertion holes 2212 are provided in two groups, penetrate the interior of the support seat 221 and are located on both sides of the first insertion holes 2211, and are used to accommodate the fastening bolts 153;

[0053] A bearing rod 223, fixedly connected to the lower end of the support seat 221, is used to raise the concrete wall 11, and the lower end edge of the bearing rod 223 is set as an arc surface 2231;

[0054] The fixing block 224 is fixedly connected to the middle of the bearing rod 223 and is used to cooperate with the fastening assembly 21 to fasten the bearing rod 223 .

[0055] Furthermore, a bearing rod 223 is fixedly connected to the upper end of the support seat 221 near the edge, and is used to limit one end of the concrete wall 11 relative to the insulation board 12.

[0056] As an improvement, Figure 6 As shown, the fastening assembly 21 includes:

[0057] The screw rod 211 has one end passing through the fixing block 224 and the mounting hole 1511 and is threadedly connected to the support beam 101. The support beam 101 is provided with a first threaded hole 1011 adapted to the thread on the outside of the screw rod 211. The fixing block 224 is provided with a third insertion hole 2241 for passing the screw rod 211.

[0058] A limiting plate 212 is fixedly connected to one end of the screw rod 211, the outer diameter of the limiting plate 212 is larger than the diameter of the thread, and is used to tighten and limit one end of the fixing block 224;

[0059] The rotating rod 213 is fixedly connected to one end of the limiting plate 212 opposite to the screw rod 211 and is used for rotating and adjusting the screw rod 211 .

[0060] Further, such as Figure 1-2 As shown, the prefabricated component unit 1 also includes:

[0061] A lifting rod 13, embedded in one end of the concrete wall 11 relative to the flip support assembly 22, is used to cooperate with the steel wire rope of the crane to lift and flip the concrete wall 11;

[0062] A reserved hole 14 is provided inside the concrete wall 11 and above the embedding rod 151 , and is used to install and fix the top of the concrete wall 11 to other components through the reserved hole 14 .

[0063] Furthermore, the height of the support beam 101 is equal to the height of the bearing rod 223 , so as to cooperate with the bearing rod 223 to support the limit block 222 .

[0064] It should be supplemented that one end of the embedded rod 151 in the present invention is inserted into the concrete during the pouring process of the concrete wall 11, so that after the concrete wall 11 is demoulded, one end of the embedded rod 151 is fixedly inserted into the inside of the concrete wall 11, wherein two groups of embedded rods 151 are fixedly inserted at the bottom of each concrete wall 11.

[0065] It should be noted that: in the specific implementation process of the present invention, Figure 3 , Figure 5 As shown, initially, the concrete wall 11 is horizontally placed on the foundation 100. When the concrete wall 11 needs to be erected and flipped, one end of the support seat 221 is first placed against one side of the fastening rod 152, so that the end of the embedded rod 151 located outside the concrete wall 11 passes through the first insertion hole 2211 and the fastening bolt 153 corresponds to the second insertion hole 2212, and then the fastening bolt 153 is screwed into the second threaded hole 1521 after passing through the second insertion hole 2212. At this time, the support seat 221 is fastened to the concrete wall 11 through the fastening rod 152, ensuring that when the support seat 221 supports the concrete wall 11 to flip, the support seat 221 will not slide relative to the concrete wall 11, so as to prevent the concrete prefabricated component from slipping off and being damaged from the support seat 221.

[0066] like Figure 1-2 As shown, one end of the steel wire rope connected to the crane is then tied to the outside of the lifting rod 13, and the crane is started. The crane drives the lifting rod 13 to move upward through the steel wire rope, and the lifting rod 13 drives the concrete wall 11 to gradually flip upward from a horizontal state. The concrete wall 11 drives the bearing rod 223 to flip through the embedded rod 151 and the support seat 221. The bearing rod 223 first contacts the foundation 100 through the arc surface 2231 and gradually flips until the concrete wall 11 and the insulation board 12 are erected synchronously. During the entire flipping process, the lower edge of the insulation board 12 is never in direct contact with the foundation 100, which effectively prevents the edge of the insulation board 12 from being compressed and damaged during the flipping process.

[0067] like Figure 4-6As shown, after the precast concrete component is flipped from a horizontal position to an upright position, the bearing rod 223 supports the concrete wall 11 vertically upward through the support seat 221. At this time, the third insertion hole 2241, the first threaded hole 1011, and the mounting hole 1511 are on the same axis, and the screw 211 is used to pass through the third insertion hole 2241 and the mounting hole 1511 in sequence and enter the first threaded hole 1011, and one end of the screw 211 is threadedly connected to the first threaded hole 1011, and the other end locks the fixing block 224 through the limit plate 212, so that one side of the lower part of the support seat 221 is supported on the foundation 100 by the bearing rod 223, and the other side of the lower part of the support seat 221 is supported by the support beam 101, thereby completing the assembly of the concrete wall 11, wherein the support seat 221 is used as a supporting component for assembling the concrete wall 11 and does not need to be removed, thereby improving the assembly efficiency of the concrete wall 11.
