Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a steel tie rod installation and positioning device and an installation method. Background Art

[0002] A steel tie rod is a commonly used connecting member in the field of building construction. According to different usage scenarios, there are various configurations for the connection structures at both ends of the steel tie rod. For example, steel hinge seats are respectively arranged at both ends of the steel tie rod to be connected with steel members respectively, or end embedded parts are respectively arranged at both ends of the steel tie rod to be connected with concrete members; when constructing a wharf, there is a horizontally arranged steel tie rod, one end of which is connected with an anchor plate to be anchored in the concrete structure of the wharf steel sheet pile, and the other end is provided with an end embedded part to be connected with other members. However, in order to ensure the stable connection between the steel tie rod and the steel sheet pile, the anchor plate often has a large volume and weight, which will cause the weight imbalance at both ends of the steel tie rod. Before pouring concrete to fix the anchor plate, the end with the end embedded part will tilt up, and the end with the anchor plate will sink. Measures need to be taken to ensure the stability of the steel tie rod during construction.

[0003] The prior art generally adopts the method of welding and connecting the steel tie rod with existing steel structures (such as steel pipe piles or temporarily erected steel supports) to stabilize the steel tie rod. However, this method will, on the one hand, require a large amount of welding operations and corresponding personnel and equipment, thus greatly increasing the construction cost and construction period. On the other hand, there is also a risk that the bearing capacities of the existing steel structure and the steel tie rod are weakened by the high temperature and stress generated by welding, which will increase the potential safety hazards of construction quality. Therefore, it is urgent to develop a new type of steel tie rod installation and positioning device. Summary of the Invention

[0004] The purpose of the present invention is to overcome the technical problems in the prior art that due to the weight imbalance at both ends of the steel tie rod, it is necessary to weld and connect the steel tie rod with existing steel structures, resulting in an increase in construction cost, construction period and potential safety hazards of construction quality, and to provide a steel tie rod installation and positioning device and an installation method.

[0005] In a first aspect, the present invention provides a steel tie rod installation and positioning device, including a pressure carrier block. The pressure carrier block is divided into at least two segments along the height direction or the horizontal direction, and a limiting groove is arranged between adjacent two segments; at least one side of the limiting groove is open, and the end embedded part of the steel tie rod can extend into the limiting groove from the opening of the limiting groove.

[0006] When the steel tie rod installation and positioning device of the present scheme is in use, the ballast block is set at the end embedded part of the steel tie rod, and the end embedded part is inserted into the limiting groove. The weight of the ballast can be used to balance the weight of the anchor plate at the other end of the steel tie rod, thereby avoiding the situation where one end of the steel tie rod is lifted and the other end sinks. Moreover, the present scheme only needs to insert the end embedded part into the limiting groove without any welding operation. Therefore, the technical problem of increased construction cost and construction period caused by welding operation and corresponding personnel and equipment can also be avoided.

[0007] At the same time, compared with the use of an integral ballast block, the ballast block of this scheme is composed of at least two sections, and the size and weight of a single section are smaller, which can not only reduce the difficulty of producing and transporting the sections; it can also help the staff to more conveniently and quickly limit the end embedded parts in the limit groove, and remove the ballast block after completing the fixation of the steel tie rod, thereby greatly improving the installation and positioning efficiency of the steel tie rod and reducing the construction period; and the removed ballast block can also be reused, which can further reduce the construction cost of this scheme.

[0008] For example, if the ballast body is divided into two sections in the horizontal direction, the staff can first transport the two sections to the two sides of the end embedded parts in the horizontal direction, and then pull the two sections closer to each other until the two sections touch each other and limit the end embedded parts in the limit groove; and when the anchor plate is fixed by concrete, the two sections are pulled away from each other to expose the end embedded parts again, which can be used to connect other designated steel structures. This division method allows both sections to be dragged directly on the ground when pulling the sections, thereby reducing the demand for traction of the pulling equipment, and is suitable for occasions with good ground flatness.

[0009] If the ballast is divided into two sections along the height direction, the staff can first pull one section to the bottom of the end embedded part, and then hoist the other section to the top of the embedded part until the two sections touch each other and the end embedded part is limited in the limit groove; and when the anchor plate is fixed by concrete, the upper section is lifted away and the lower section is pulled away from the end embedded part, so that the end embedded part can be exposed again and can be used to connect other designated steel structures. This segmentation method can use the dead weight of the section to prevent the two sections from accidentally separating from each other, and is suitable for occasions with high requirements for the stability of the steel tie rod.

[0010] Preferably, the ballast body block is divided into two sections along the height direction, and a first groove is arranged on a surface of each section facing the other section, and the two first grooves are combined into a limiting groove.

[0011] In this scheme, the ballast body block includes two sections stacked on each other in the height direction. On the one hand, the upper section can be firmly loaded on the upper surface of the lower section under the action of its own weight, so that this scheme can avoid the two sections from accidentally separating from each other, causing the steel pull rod to fall out of the limit groove and become unstable.

[0012] On the other hand, the present solution is provided with a first groove on both segments, that is, the upper surface of the lower segment and the lower surface of the upper segment are both provided with a first groove. When the two segments are stacked on each other, the two first grooves can be combined into a limiting groove; so that when the lower segment is first arranged under the end embedded part during construction, the first groove of the lower segment can first limit the end embedded part in the horizontal direction; and when the upper segment is stacked with the lower segment, the end embedded part partially extended into the first groove of the upper segment can produce a horizontal limiting effect on the upper segment; that is, the present solution can suppress the horizontal displacement or movement of the end limiting part and the upper segment throughout the construction process, thereby further improving the stability of the steel tie rod and the ballast body block throughout the construction process.

[0013] Preferably, each segment is provided with a lifting lug.

[0014] This solution can facilitate workers or construction equipment to use the lifting lug as a force application point to pull or lift the segment.

[0015] Preferably, the lifting lug is arranged on a side of the segment facing away from the opening of the limiting groove, and / or the lifting lug is arranged on the upper surface of the segment.

[0016] When the lifting lug is set on the side of the segment away from the opening of the limit groove, this solution can facilitate the staff to pull the segment away from the steel pull rod, thereby separating the end embedded parts and the limit groove from each other; when the lifting lug is set on the upper surface of the segment, this solution can facilitate the staff to lift the segment in the height direction, thereby separating two adjacent segments from each other.

[0017] Preferably, one of the two adjacent segments is provided with a lifting ear on a surface facing the other segment, and a second groove is provided at a corresponding position on the other segment, and the lifting ear extends into the second groove.

[0018] This solution can not only avoid interference between the lifting ear and the segmented structure through the second groove, but also enable two adjacent segments to form a mortise and tenon connection through the lifting ear and the second groove, thereby further enhancing the limiting and connection stability between the two adjacent segments.

[0019] Preferably, a metal plate is provided on the inner wall of the limiting groove, and the metal plate is used to contact the end embedded part.

[0020] In this solution, the inner wall of the limiting groove is replaced by a metal plate to directly contact the end embedded part, so that the limiting groove and the end embedded part can be prevented from scratching each other.

[0021] Preferably, a metal box is arranged in the limiting groove, and a side of the metal box close to the opening of the limiting groove is also open, and the end embedded part can extend into the metal box from the opening of the metal box.

[0022] In this solution, a metal box is arranged in the limit groove, and the side wall of the metal box can be used as a metal plate, which can directly contact the end embedded part instead of the inner wall of the limit groove; and compared with pasting or embedding the metal plate on the inner wall of the limit groove, the present solution uses an integral metal box, and the metal box can be placed in the limit groove by utilizing the shape of the limit groove and the metal box, which can avoid complicated pasting or embedding processes, thereby reducing the manufacturing cost of the pressure bearing block; and when the metal plate needs to be replaced due to wear or changes in the size specifications of the end embedded part, the metal box of this solution is also easier to disassemble and reassemble.

[0023] Preferably, the interior of the metal box is filled with foam glue.

[0024] This solution can further reduce the probability of damage to the end embedded parts.

[0025] In a second aspect, the present invention provides a steel tie rod installation method, which is applied to a steel tie rod installation and positioning device of the present invention, comprising the following steps: S1. Install the steel tie rod at the designated position; move the segments to the end embedded parts of the steel tie rod, connect the segments to each other, and make the end embedded parts be limited in the limit groove between two adjacent segments; S2. Pour concrete at the anchor plate of the steel tie rod to fix the steel tie rod; S3. Separate the segments from each other and transport them away from the site, exposing the embedded parts at the ends.

[0026] The steel tie rod installation method of the present invention temporarily balances the weight of the anchor plate through the steel tie rod installation positioning device of the present invention during construction, which can avoid a large amount of welding work and corresponding personnel and equipment, thereby improving the construction efficiency of the steel tie rod installation work and reducing construction costs and construction periods.

[0027] Preferably, when the ballast body block is divided into two sections along the height direction, step S3 comprises the following steps: S31, lifting the upper segment to separate the two segments from each other; S32, pull the segment located at the bottom in a direction away from the steel tie rod until the end embedded part is separated from the segment.

[0028] This scheme recommends that when the ballast body block is divided into two sections along the height direction and the ballast body block needs to be removed, the upper section should be lifted away first and then the lower section should be towed away. On the one hand, this can avoid removing the lower section first, which would cause the load of the upper section to act directly on the steel tie rod, thereby causing the steel tie rod to bend or even be damaged. On the other hand, the operation of towing the lower section to separate it from the embedded parts can avoid lifting the lower section, thereby avoiding direct confrontation with the deadweight of the lower section, making the separation operation more labor-saving and quick, and can further improve the construction efficiency of this scheme.

[0029] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a steel tie rod installation and positioning device, which can balance the weight of the anchor plate at the other end of the steel tie rod through the weight of the pressure body, thereby avoiding the situation where one end of the steel tie rod is lifted and the other end sinks; and this solution only needs to insert the end embedded part into the limit groove without any welding operation, so it can also avoid the technical problems of increased construction cost and construction period caused by welding operations and corresponding personnel and equipment.

[0030] 2. The present invention provides a steel tie rod installation method. During construction, the weight of the anchor plate is temporarily balanced by the steel tie rod installation positioning device of the present invention, which can avoid a large amount of welding work and corresponding personnel and equipment, thereby improving the construction efficiency of the steel tie rod installation operation and reducing the construction cost and construction period.

[0038] Embodiment 1 As Figures 1 to 5 shown, a steel tie rod installation and positioning device includes a pressure carrier block 1. The pressure carrier block 1 is divided into at least two segments 10 along the height direction or the horizontal direction. A limiting groove 2 is provided between two adjacent segments 10; the limiting groove 2 is used to open towards one side of the steel tie rod 5, and the end embedded part 51 of the steel tie rod 5 can extend into the limiting groove 2 from the opening of the limiting groove 2.

[0039] In Figures 2 to 7 it, a three-axis coordinate system is also used to facilitate distinguishing the orientations of each drawing. The X-axis, Y-axis, and Z-axis in the three-axis coordinate system are perpendicular to each other in pairs, where the X-axis and Y-axis are located in the horizontal plane, and the Z-axis is parallel to the height direction.

[0040] In the above-mentioned embodiment, the limiting groove 2 is provided between two adjacent segments 10, that is, the limiting groove 2 is formed by enclosing two adjacent segments 10. Taking the case where the pressure carrier block 1 is divided into two segments 10 along the height direction, and the two segments 10 are respectively an upper segment 10 and a lower segment 10 as an example, a groove structure can be provided on the surface of the upper segment 10 facing the upper segment 10 or the surface of the lower segment 10 facing the upper segment 10. After the upper segment 10 and the lower segment 10 are mutually assembled, the groove structure can enclose the limiting groove 2 together with the upper surface of the lower segment 10 or the lower surface of the upper segment 10; or a groove structure can also be provided on both the surface of the upper segment 10 facing the upper segment 10 and the surface of the lower segment 10 facing the upper segment 10, and the positions of the two groove structures match each other. Thus, after the upper segment 10 and the lower segment 10 are mutually assembled, the two groove structures can enclose the limiting groove 2 together.

[0041] In an optional embodiment, the connection method between two adjacent segments 10 includes but is not limited to connection by a threaded connector, mortise and tenon connection, or pin connection. Or a connection structure may not be specifically provided, and the mutual assembly between two adjacent segments 10 is maintained by the friction between the two segments 10.

[0042] In an optional embodiment, as Figure 3As shown, the pressure carrier block 1 is divided into two segments 10 in the height direction. On one side of each of the two segments 10 facing the other segment 10, a first groove 101 is provided, and the two first grooves 101 are joined together to form a limiting groove 2. It should be noted that due to the shielding of the metal box 4, Figure 3 the joint between the two first grooves 101 in Figure 3 is in an invisible state, so a dotted line is used to mark the joint between the two first grooves 101.

[0043] In an alternative embodiment, lifting lugs 3 are respectively provided on each segment 10.

[0044] In the above embodiment, the lifting lug 3 is provided on the side of the segment 10 facing away from the opening of the limiting groove 2, and / or the lifting lug 3 is provided on the upper surface of the segment 10. For example Figure 5 as shown, lifting lugs 3 are provided on the upper surfaces of the two segments 10 to facilitate vertical lifting; an additional lifting lug 3 is also provided on the side of one of the segments 10 facing away from the opening of the limiting groove 2 (i.e., the side facing away from the steel tie rod 5) to facilitate subsequent pulling and traction operations.

[0045] In the above embodiment, at least two lifting lugs 3 are provided at intervals on each segment 10 to enhance the stability of the hoisting operation or the pulling and traction operation.

[0046] In the above embodiment, in one of the two adjacent segments 10, a lifting lug 3 is provided on the side facing the other segment 10, and a second groove 102 is provided at the corresponding position on the other segment 10, and the lifting lug 3 extends into the second groove 102. For example Figure 5 as shown, when the pressure carrier block 1 is divided into upper and lower two segments 10 in the height direction, a lifting lug 3 is provided on the upper surface of the lower segment 10, a second groove 102 is provided on the lower surface of the upper segment 10, and the lifting lug 3 extends into the second groove 102, which can not only avoid interference between the lifting lug 3 and the structure of the segment 10, but also enhance the connection stability between the two segments 10.

[0047] In an alternative embodiment, the pressure carrier block 1 is a concrete material component.

[0048] In an alternative embodiment, the self-weight of the pressure carrier block 1 is greater than or equal to three tons to ensure sufficient safety margin during the installation process of the steel tie rod 5.

[0049] In an alternative embodiment, a metal plate is provided on the inner wall of the limiting groove 2 for contacting the end embedded part 51. The specific ways of providing the metal plate on the inner wall of the limiting groove 2 include but are not limited to: the metal plate is embedded in the inner wall of the limiting groove 2, or the metal plate is pasted on the inner wall of the limiting groove 2; the metal plate can be fully laid in all areas of the inner wall of the limiting groove 2, or only locally laid in the areas that will contact the end embedded part 51.

[0050] In the above embodiments, as Figure 3 and Figure 4 shown, a metal box 4 is provided in the limiting groove 2. One side of the metal box 4 close to the opening of the limiting groove 2 is also open ( Figure 4 the left side in the X-axis direction in ), and the end embedded part 51 can extend into the metal box 4 from the opening of the metal box 4.

[0051] In the above embodiments, the shape and size of the metal box 4 match those of the limiting groove 2, so that the metal box 4 can be directly inserted into the limiting groove 2 without the need for various additional connection operations such as welding connection, threaded connection or snap connection, thereby facilitating the disassembly, installation and replacement of the metal box 4.

[0052] In the above embodiments, the hardness of the metal box 4 is less than that of the end embedded part 51, thereby further reducing the probability of the end embedded part 51 being scratched.

[0053] In the above embodiments, the metal box 4 is filled with foam glue.

[0054] Embodiment 2 A method for installing a steel tie rod, which is applied to a steel tie rod installation and positioning device in Embodiment 1, includes the following steps: S1. Install the steel tie rod 5 at a specified position. For example, Figures 1 to 2 as shown, pass the steel tie rod 5 through the side wall of the steel pipe pile 6, and the end with the end embedded part 51 is located outside the steel pipe pile 6, and the end for installing the anchor plate 52 is located inside the steel pipe pile 6; move the segment 10 to the end embedded part 51 of the steel tie rod 5 and connect the segments 10 to each other so that the end embedded part 51 is limited in the limiting groove 2 between two adjacent segments 10.

[0055] S2. Pour concrete at the anchor plate 52 of the steel tie rod 5 to fix the steel tie rod 5.

[0056] S3. After the concrete solidifies and reaches the specified strength, separate the segments 10 from each other and transport them away from the site, so that the end embedded part 51 is exposed again for subsequent connection with other existing structures.

[0057] In an alternative embodiment, when the pressure carrier block 1 is divided into two segments 10 in the height direction, step S3 includes the following steps: S31. As Figure 6 shown, lift the upper segment 10 upward in the direction indicated by the arrow D to separate the two segments 10 from each other.

[0058] S32. As Figure 7 shown, pull the lower segment 10 in the direction away from the steel tie rod 5 in the direction indicated by the arrow E until the segment 10 is separated from the end embedded part 51.

[0059] In an optional embodiment, when moving the segment 10, the lifting lug 3 of the segment 10 can be connected to a traction device, such as a crane or an excavator, through a cable, and then the segment 10 can be moved by hooking or moving the traction device.

[0060] In an optional embodiment, when the segment 10 is pulled in a direction away from the steel tie rod 5 , the corresponding segment 10 is directly pulled and dragged on the ground to avoid directly confronting the deadweight of the segment 10 , thereby reducing the difficulty of moving the segment 10 .

[0061] In an optional implementation, after the end embedded part 51 is inserted into the limiting groove 2, the anchor plate 52 is installed on the steel tie rod 5 to ensure the stability of the steel tie rod 5 before the ballast body block 1 is in place.

[0062] In the above embodiment, before the segment 10 is moved to the end embedded part 51 , the ground at the predetermined installation position of the segment 10 is sanded and leveled, thereby further reducing the difficulty of moving the segment 10 .

[0063] The above contents are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
