Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a construction auxiliary device and a hoisting structure component. Background Technology

[0002] In the prefabrication of columns, vertical casting is typically used. After casting, to facilitate transport to the hoisting site, the columns need to be flipped from a vertical to a horizontal position. However, large-section prefabricated columns face numerous difficulties during this flipping process. These columns are large and heavy, prone to instability during flipping, posing significant safety hazards. They cannot be flipped by their own weight alone and require external assistance. Currently, most flipping methods rely on traditional lifting equipment, using the column's own weight directly for the flipping. This method cannot ensure the safety and efficiency of flipping large-section columns, easily leading to component damage, affecting product quality, increasing production costs, and potentially causing safety accidents and delaying construction. Therefore, there is an urgent need for an auxiliary device that can safely, efficiently, and quickly flip large-section prefabricated columns. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the difficulties in flipping large-sized components during construction, the easy damage to components during the flipping process, and the low efficiency of construction operations in the existing technology, and to provide a construction auxiliary device and a hoisting structure component.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A construction auxiliary device includes a first mounting part and a second mounting part, the first mounting part being connected to the second mounting part. The cross-sectional shape of the first mounting part is adapted to the inner wall shape of the grouting sleeve so that the first mounting part can be inserted into the grouting sleeve. The second mounting part has a first end on the side away from the connection with the first mounting part, which is connected to a hoisting device so that the second mounting part can be connected to the hoisting device.

[0006] In this design, efficient and non-destructive hoisting is achieved through the use of a first installation section and a second installation section. The cross-sectional shape of the first installation section matches the inner wall of the grouting sleeve, allowing for smooth insertion into the existing sleeve without the need for additional drilling into the precast component. This effectively maintains the structural integrity and overall stability of the component while simplifying the construction preparation process. Furthermore, the second installation section connects to the hoisting equipment, enabling the crane to directly lift the component. This avoids structural modifications or temporary reinforcements to accommodate hoisting, significantly reducing on-site work time and labor costs. This design improves construction efficiency while enhancing the safety and reliability of the hoisting process, demonstrating excellent engineering applicability.

[0007] Preferably, a connecting member is further provided at the connection between the first mounting part and the second mounting part, the connecting member being used for the transition connection between the first mounting part and the second mounting part; wherein, the connecting member is connected to the first mounting part through a first plane located on the surface, the area of ​​the first plane being larger than the area of ​​the connection surface where the first mounting part and the connecting member are connected.

[0008] Preferably, the connector is connected to the second mounting portion via a second plane located on the surface, and the area of ​​the second plane is larger than the area of ​​the connection surface where the second mounting portion connects to the connector.

[0009] In this solution, by setting a connector at the connection point between the first and second mounting parts, the area of ​​the first plane connecting the connector to the first mounting part is larger than the area of ​​the connection surface between the first mounting part and the connector, and the area of ​​the second plane is larger than the area of ​​the connection surface between the second mounting part and the connector. This allows the connector to provide a larger connection plane between the first and second mounting parts, resulting in a more secure connection. The indirect connection between the first and second mounting parts via the connector enables the construction auxiliary device to have better load-bearing capacity, improving the safety and stability of the device.

[0010] Preferably, the first mounting portion includes a second end located at the end of the first mounting portion away from the second mounting portion, and the radial cross-sectional area of ​​the second end decreases along the axial direction away from the second mounting portion, so that the second end can guide the first mounting portion to be inserted into the grouting sleeve.

[0011] Preferably, the second end is truncated cone-shaped.

[0012] In this design, a second end is provided at the end of the first mounting part furthest from the second mounting part. The cross-sectional area of ​​this second end decreases along the axial direction away from the second mounting part, allowing the conical second end to function as a guide head, enabling rapid and accurate alignment and insertion during installation. This structure, utilizing its conical slope, automatically guides and corrects itself upon contact with the grouting sleeve at the bottom of the column, effectively avoiding installation difficulties or structural damage caused by alignment deviations. During construction, workers can easily slide the first mounting part into the pre-embedded grouting sleeve using this guide head, significantly reducing adjustment time and manual intervention, thus achieving a quick and reliable installation and further improving overall construction efficiency and assembly quality.

[0013] Preferably, the first mounting part includes a second end, and the portion of the first mounting part other than the second end is a cylindrical structure, wherein the ratio of the radial cross-sectional area of ​​the cylindrical structure to the inner wall cross-sectional area of ​​the grouting sleeve is 0.8.

[0014] Preferably, the first end is offset from the axis of the first mounting portion.

[0015] In this solution, by setting the first end to be offset from the axis of the first mounting part, when the hoisting equipment is connected to the first end and hoisting operation is performed, the stress borne by the connection between the first mounting part and the connecting piece, and between the second mounting part and the connecting piece, can be reduced, thus avoiding stress concentration that could damage the interface and compromise the structural stability.

[0016] Preferably, the ratio of the axial length of the cylindrical structure to the inner wall depth of the grouting sleeve is 0.4.

[0017] Preferably, the first end further includes a connecting hole for inserting the hook of the hoisting equipment, and the axial direction of the connecting hole is perpendicular to the axial direction of the first mounting part.

[0018] Preferably, the outer edge of the first end away from the first mounting portion has an arc shape.

[0019] Preferably, the shape of the outer edge of the first end away from the first mounting part corresponds to the shape of the connecting hole.

[0020] In this solution, by setting the outer edge of the first end away from the first mounting part to be an arc, the frequent collision between the hoisting equipment and the end of the second mounting part during hoisting operations can be avoided, which would reduce construction efficiency. At the same time, it can also reduce the wear and tear on the equipment caused by friction.

[0021] Preferably, the construction auxiliary device is made of low-alloy high-strength structural steel.

[0022] A hoisting structure assembly includes hoisting equipment and construction auxiliary devices as described above.

[0023] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0024] The positive and progressive effects of this utility model are as follows:

[0025] Efficient and non-destructive hoisting is achieved by setting up a first installation section and a second installation section. The cross-sectional shape of the first installation section matches the inner wall of the grouting sleeve, allowing for smooth insertion into the existing grouting sleeve without the need for additional drilling into the precast component. This effectively maintains the structural integrity and overall stability of the component while simplifying the construction preparation process. Furthermore, the second installation section connects to hoisting equipment, allowing the crane to directly lift the component. This avoids structural modifications or temporary reinforcements to accommodate hoisting, significantly reducing on-site work time and labor costs. This design improves construction efficiency while enhancing the safety and reliability of the hoisting process, demonstrating excellent engineering applicability. Attached Figure Description

[0042] The present invention is further illustrated below by way of embodiments, but these embodiments do not limit the present invention to the scope of the embodiments described. Experimental methods in the following embodiments that do not specify specific conditions are performed according to conventional methods and conditions, or as selected according to the product instructions.

[0043] like Figures 1-2 As shown, this embodiment provides a construction auxiliary device 001, which includes a first mounting part 1 and a second mounting part 2. The first mounting part 1 is connected to the second mounting part 2. The cross-sectional shape of the first mounting part 1 is adapted to the inner wall shape of the grouting sleeve 4 so that the first mounting part 1 can be inserted into the grouting sleeve 4. The second mounting part 2 has a first end 21 connected to the hoisting equipment 5 on the side away from the first mounting part 1 so that the second mounting part 2 can be connected to the hoisting equipment 5.

[0044] The efficient and non-destructive hoisting of precast components is achieved through the cooperation of the first installation part 1 and the second installation part 2. The cross-sectional shape of the first installation part 1 matches the inner wall of the grouting sleeve 4, allowing for smooth insertion into the existing sleeve without the need for additional holes in the component. This not only fully maintains the structural integrity and wholeness of the component but also simplifies the preliminary construction preparation work. The second installation part 2 is used to connect the hoisting equipment 5, allowing the crane to directly lift the component through this part. This avoids structural modifications or temporary reinforcement of the component due to hoisting requirements, significantly reducing on-site operation time and labor costs. This design improves construction efficiency while also enhancing the safety and reliability of the hoisting process, demonstrating broad engineering applicability.

[0045] like Figures 1-2 As shown, a connecting member 3 is also provided at the connection between the first mounting part 1 and the second mounting part 2. The connecting member 3 is used for the transition connection between the first mounting part 1 and the second mounting part 2. The connecting member 3 is connected to the first mounting part 1 via a first plane 31 located on its surface. The area of ​​the first plane 31 is larger than the area of ​​the connection surface between the first mounting part 1 and the connecting member 3. The connecting member 3 is connected to the second mounting part 2 via a second plane 32 located on its surface. The area of ​​the second plane 32 is larger than the area of ​​the connection surface between the second mounting part 2 and the connecting member 3. In this embodiment, the connecting member 3 is a steel plate with a rectangular cross-section, made of Q345 low-alloy high-strength structural steel. The first plane 31 and the second plane 32 are the two planes with the largest surface areas of the rectangular steel plate, and the first plane 31 and the second plane 32 are arranged opposite to each other. In this embodiment, a connector 3 is provided at the connection point between the first mounting part 1 and the second mounting part 2. The area of ​​the first plane 31 of the connector 3 connected to the first mounting part 1 is larger than the area of ​​the corresponding connection surface on the first mounting part 1 connected to the connector 3. Simultaneously, the area of ​​the second plane 32 of the connector 3 connected to the second mounting part 2 is also larger than the area of ​​the corresponding connection surface on the second mounting part 2 connected to the connector 3. Through this structural design, the connector 3 provides a larger effective connection plane for the first mounting part 1 and the second mounting part 2, significantly enhancing the connection strength. The indirect connection achieved through the connector 3 further improves the overall load-bearing capacity of the construction auxiliary device 001, thereby effectively improving the safety and stability of the device.

[0046] In other embodiments, the shape of the connector 3 can also be other shapes such as frustum or cylinder with a large connecting plane, and the material can also be other materials that can be firmly connected with the first mounting part 1 and the second mounting part 2, which will not be described in detail here.

[0047] like Figures 1-2 As shown, the first mounting part 1 includes a second end 11, located at the end of the first mounting part 1 away from the second mounting part 2. The radial cross-sectional area of ​​the second end 11 decreases along the axial direction away from the second mounting part 2. The second end 11 is truncated cone-shaped, allowing it to guide the first mounting part 1 into the grouting sleeve 4. This truncated cone-shaped second end 11 acts as a guide head, enabling rapid and accurate alignment and insertion during installation. This structure, utilizing the beveled surface of its truncated cone shape, can automatically guide and correct itself when in contact with the grouting sleeve 4 at the bottom of the column, effectively avoiding installation difficulties or structural damage caused by alignment deviations.

[0048] In this embodiment, the first mounting part 1, except for the second end 11, is a cylindrical structure. The second end 11 is connected to the top surface of the cylindrical structure by the bottom surface of the larger frustum. The ratio of the radial cross-sectional area of ​​the cylindrical structure to the cross-sectional area of ​​the inner wall of the grouting sleeve 4 is 0.8. The first mounting part 1 and the grouting sleeve 4 are in clearance fit or transition fit, which helps to achieve quick insertion. At the same time, it also provides space for the first mounting part 1 to be positioned in the grouting sleeve 4 during the hoisting operation, so that irreversible damage will not occur due to stress concentration on the surface of the first mounting part 1 due to insufficient space. It also protects the structural integrity of the inner wall of the grouting sleeve 4. The ratio of the axial length of the cylindrical structure to the inner wall depth of the grouting sleeve 4 is 0.4.

[0049] like Figures 1-2 As shown, in this embodiment, the first end 21 is offset from the axis of the first mounting part 1. The first end 21 also includes a connecting hole 211 for inserting the hook of the hoisting equipment 5. The axis of the connecting hole 211 is perpendicular to the axis of the first mounting part 1. The outer edge of the first end 21 away from the first mounting part 1 is arc-shaped, and the shape of the outer edge of the first end 21 away from the first mounting part 1 corresponds to the shape of the connecting hole 211. The second mounting part 2 is a square steel plate with one end in an arc shape. The connecting hole 211 is located on the plane with the largest surface area of ​​the steel plate and penetrates through the steel plate. The second mounting part 2 is welded to the connecting piece 3 through the side with the largest area extending along the thickness direction. In this embodiment, the shape of the first end 21 is designed to be arc-shaped and is located away from the outer edge of the first mounting part 1, which can effectively avoid frequent collisions between the equipment and the end of the second mounting part 2 during hoisting operations, thereby improving construction efficiency and reducing equipment wear caused by friction.

[0050] In other embodiments, the edge of the second mounting part 2 away from the first mounting part 1 can be of other shapes to facilitate connection with the hoisting equipment 5, which will not be described in detail here.

[0051] In this embodiment, the construction auxiliary device 001 is made of low-alloy high-strength structural steel, specifically Q345 low-alloy high-strength structural steel.

[0052] like Figure 3 As shown, in this embodiment, the grouting sleeve 4 is set at the end where the component to be hoisted is connected to the hoisting equipment 5. The grouting sleeve 4 is arranged at equal intervals along the end edge of the structure to be hoisted. The size and number of the grouting sleeve 4 are determined by the structural design requirements, and the number of construction auxiliary devices 001 is adjusted according to the construction operation requirements.

[0053] This embodiment also provides a hoisting structure component 002, which includes a hoisting device 5 and a construction auxiliary device 001 as described above. The construction auxiliary device 001 is used to cooperate with the crane auxiliary hook in the hoisting device 5. The construction auxiliary device 001 is assembled in a precast grouting sleeve 4 set on the bottom surface of the component to be hoisted. After the auxiliary hook is connected to the connection hole 211 on the construction auxiliary device 001, the component to be hoisted is flipped through cooperation with the crane main hook.

[0054] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
