Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a connection device for precast main beams and precast columns. Background Technology

[0002] Many substations still utilize concrete structural systems in their construction, with beams, slabs, and columns all prefabricated. One issue discovered during installation is that existing prefabricated main beams are installed via hoisting. During hoisting, these beams inevitably tilt, requiring manual alignment by workers. This demands high skill from the hoisting personnel and poses safety hazards, as manual adjustment is necessary. Furthermore, prefabricated columns typically have at least two main beams installed, especially when two are installed in parallel, requiring manual parallel adjustment, which is extremely cumbersome.

[0003] Therefore, there is an urgent need for a precast main beam and precast column connection device that can connect the precast main beam and precast column and ensure parallelism between two precast main beams, thereby solving manpower issues and improving construction efficiency. Utility Model Content

[0004] In view of this, the present invention provides a connection device for precast main beams and precast columns, which can simultaneously detect and adjust the two precast main beams.

Each connecting component includes a sliding rod with a connecting part for connecting with the precast main beam. The connecting plate is provided with an adjusting component for adjusting the interval between the two connecting components.

[0007] Optionally, the adjusting assembly includes a bidirectional screw and a sliding seat. The bidirectional screw is rotatably mounted on a connecting plate, and the sliding seat is threaded to both ends of the bidirectional screw. The connecting assembly is mounted on the corresponding sliding seat, and the bidirectional screw can be rotated maneuverably.

[0008] Optionally, the connecting assembly includes a mounting plate, a sliding rod, and a suction cup. The sliding rod is slidably fitted onto the mounting plate, the mounting plate is mounted on a sliding seat, and the suction cup is located at the end of the sliding rod. The suction cup is used to adsorb the precast main beam.

[0009] Optionally, multiple sets of sliding rods are provided on the same connecting assembly along the length direction of the bidirectional screw. Multiple sliding rods are provided in the vertical direction, and the sliding rods can be manipulated to slide along the length direction perpendicular to the bidirectional screw.

[0010] Optionally, the sliding rod includes a screw, and a sleeve is rotatably fitted on the mounting plate. The screw is threadedly connected to the sleeve, and the sleeve can be driven to rotate.

[0011] Optionally, a fixing plate is provided between the sliding rods of the same group of connecting components, and the screw is driven to move by the sleeve, which in turn drives the sliding rods of the same group to slide through the fixing plate.

[0012] Optionally, a length sensor for detecting the distance between the mounting plate and the fixing plate is provided between the mounting plate and the fixing plate.

[0013] Optionally, the longitudinal section of the connecting plate is L-shaped.

[0014] In summary, this utility model has at least one of the following beneficial technical effects: by installing the connecting plate on the precast column, and then connecting two precast main beams to be installed in parallel through two connecting components, and adjusting the interval between the two connecting components by adjusting the component, the two precast main beams to be installed in parallel are brought closer to each other, thus completing the parallel installation of the two precast main beams on the precast column.

[0018] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0019] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.

[0020] This utility model discloses a connection device for precast main beams and precast columns.

[0021] Reference Figure 1 A precast main beam and precast column connection device includes a connecting plate 1 for connecting to the precast column. The connecting plate 1 is provided with two connecting components, each including a sliding rod 2 with a connecting part for connecting to the precast main beam. The connecting plate 1 is provided with an adjusting component for adjusting the interval between the two connecting components. The connecting plate 1 is installed on the precast column, and then two precast main beams to be installed in parallel are connected through the two connecting components respectively. By adjusting the interval between the two connecting components, the two precast main beams to be installed in parallel are brought closer to each other, thus completing the parallel installation of the two precast main beams on the precast column. This solves the problem of manually adjusting the installation of the precast main beam and precast column and improves the installation efficiency.

[0022] In this embodiment, the longitudinal section of the connecting plate 1 is L-shaped. The connecting plate 1 is fixedly installed on the precast column by fasteners, which are bolts, and the connecting plate 1 is fixed by the bolts.

[0023] The adjusting assembly includes a bidirectional screw 3 and a sliding seat. The bidirectional screw 3 is rotatably mounted on the connecting plate 1, and the sliding seat is threaded to both ends of the bidirectional screw 3. The connecting assembly is located on the corresponding sliding seat, allowing the bidirectional screw 3 to be rotated maneuverably. The bidirectional screw 3 is a screw with two threaded sections in opposite directions, used to achieve synchronous but opposite movements at both ends. The rotation of the bidirectional screw 3 enables centering, allowing the two precast main beams to be symmetrically installed on the precast columns. The bidirectional screw 3 can be rotated maneuverably, either manually or electrically, which is existing technology.

[0024] The connecting assembly includes a mounting plate 4, a sliding rod 2, and a suction cup 5. The sliding rod 2 is slidably fitted onto the mounting plate 4, which is located on a sliding seat. The suction cup 5 is located at the end of the sliding rod 2 and is used to adhere to the precast main beam. The mounting plate 4 is the foundation of the connecting assembly, providing a stable support and sliding surface for the sliding rod 2. The suction cup 5, located at the end of the sliding rod 2, is the contact point between the connecting assembly and the precast main beam. The main function of the suction cup 5 is to adhere to the precast main beam. The suction cup 5 can firmly fix the precast main beam to the suction cup 5 by generating negative pressure or using adhesive principles. The suction cup 5's adsorption of the precast main beam replaces manual adjustment, which is not only safer but also improves the convenience and accuracy of adjustment, as the suction cup 5 can only move along a predetermined track, thus preventing the precast main beam from swaying during hoisting.

[0025] Multiple sets of sliding rods 2 are arranged along the length of the bidirectional screw 3 on the same connecting component. Multiple sliding rods 2 are arranged vertically, and each sliding rod 2 can be manipulated to slide perpendicular to the length of the bidirectional screw 3. In this embodiment, two sets of sliding rods 2 are provided, with two rods in each set. Two sliding rods 2 define a straight line, and three non-linearly arranged sliding rods 2 define a plane, thus limiting the position of a single precast main beam and facilitating the parallel installation between two precast main beams later.

[0026] In this embodiment, the sliding rod 2 includes a screw and a round rod. A fixing plate 7 is provided between the sliding rods 2 of the same group of connecting components. The screw is driven to move by the sleeve 6, which in turn drives the sliding rods 2 of the same group to slide through the fixing plate 7. The screw acts as a power rod, actively driving the suction cup 5 to adsorb, while the round rod passively drives the suction cup 5 to adsorb. The sleeve 6 is rotatably fitted on the mounting plate 4. The screw and the sleeve 6 are threadedly connected, and the sleeve 6 can be driven to rotate. In this embodiment, the sleeve 6 is moved by a motor, which rotates the sleeve 6 through a gear belt. The screw is provided with a groove, and a limit block is provided on the mounting plate 4 to prevent the screw from rotating on its own.

[0027] A length sensor 8 is installed between the mounting plate 4 and the fixing plate 7 to detect the distance between them. The distance between the mounting plate 4 and the fixing plate 7 is detected by the length sensor 8. When the precast main beam is hoisted over, the sliding rods 2 of different groups of the same connecting component will respectively attract the precast main beam. After the two are attracted, the distance detected by the length sensor 8 is adjusted to be consistent and aligned with the precast column. The leveling of the precast main beam can be completed by the length sensor 8, which is very convenient.

[0028] In this embodiment, the connecting devices of this utility model are installed on both sides of the precast column, and the precast main beam is installed through the connecting devices on both sides.

[0029] This article uses specific examples to illustrate the principles and implementation methods of this utility model.
