Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated building technology, and in particular to prefabricated building beams that can be quickly connected. Background Technology
[0002] In traditional prefabricated construction, beam connections are often a critical step in the construction process, yet they also present numerous challenges. On one hand, the connection techniques are complex and time-consuming; on the other hand, they demand high levels of skill from workers. Therefore, developing prefabricated beams for rapid connection and optimizing connection structures and processes are of great significance for improving construction efficiency, ensuring project quality, and reducing costs in prefabricated construction.
[0003] To facilitate the adjustment of the length and angle of the wire rope used for hoisting prefabricated building beams and to achieve stable, centered hoisting, existing prefabricated building beams often have tracks on them for the lifting devices that engage with the hooks at the ends of the wire ropes. However, most of these lifting devices or tracks lack mechanisms for multiple stable positioning of the lifting devices, making them prone to slippage and displacement during hoisting. This can cause the hooks or wire ropes to loosen and come off, resulting in falling objects from heights. Utility Model Content
[0004] In view of this, the present invention provides a quick-connect prefabricated building beam to solve the problem that most lifting devices or tracks lack mechanisms for multiple stable positioning of the lifting devices, which causes the lifting devices to easily slide and shift during the lifting process, resulting in the hooks or wire ropes easily loosening and disengaging, and causing high-altitude falling object accidents.
[0005] The technical solution proposed by this utility model is: a quick-connecting prefabricated building beam, specifically including a building beam, wherein two symmetrically arranged T-shaped track grooves are embedded in the top of the building beam;
[0006] The T-shaped track groove has a T-shaped track groove inside. Two rectangular slide plates are slidably installed in the horizontal part of the bottom side of the T-shaped track groove. Two vertical support plates are symmetrically welded to the top of the rectangular slide plates. Rectangular sleeves are welded to the top of the two vertical support plates. A lifting plate is slidably installed through the rectangular sleeve. Two limiting blocks are symmetrically integrally formed at the bottom part of the lifting plate. When the two limiting blocks slide upward, they abut against the rectangular sleeve. A lifting ring is integrally formed at the top of the lifting plate. Two rows of friction positioning teeth are symmetrically arranged at the top of the rectangular slide plates. When the rectangular slide plates are lifted upward, the two rows of friction positioning teeth press against the two top walls of the horizontal part of the T-shaped track groove. A mounting lug is welded to the outside of one of the vertical support plates. A tightening bolt is threaded through the mounting lug. The bottom end of the tightening bolt presses against the bottom wall of the T-shaped track groove.
[0007] Furthermore, the two narrow sides of the suspension plate are integrally formed with two vertical sliding strips.
[0008] Furthermore, two vertical guide grooves are symmetrically provided on the inner side of the vertical support plate, and two vertical slide bars slide in cooperation with the two vertical guide grooves.
[0009] Furthermore, the vertical guide groove extends upward and penetrates the rectangular sleeve.
[0010] Furthermore, two reinforcing strips are symmetrically welded to both sides of the track, and these two reinforcing strips are cast and inserted into the top part of the building beam.
[0011] Furthermore, the building beam has a trapezoidal frame structure, with two rows of through assembly holes symmetrically arranged on its two inclined side plates.
[0012] Furthermore, the bottom part of the suspension plate is slidably engaged with the vertical part of the T-shaped track groove.
[0013] The quick-connecting prefabricated building beam provided by this utility model has the following beneficial effects:
[0014] First, the four rectangular sliding plates and four lifting rings can slide relative to each other along the two tracks to adjust the spacing between them. This facilitates the adjustment of the lifting angle of the four wire ropes to achieve stable and centered lifting of the building beam.
[0015] 2. Before the hoisting operation begins and the wire rope is not yet tightened, the tightening bolts can use their tightening positioning effect to position the lifting device composed of the rectangular sliding plate, the lifting plate, and the lifting ring. This prevents the lifting device from lacking necessary positioning in this state and being pulled and displaced by the subsequently straightened wire rope, causing its sliding and adjusted position to be disordered, which would affect the smooth hoisting of the building beam.
[0016] Third, the combination of two rows of friction positioning teeth and tightening bolts enables double positioning of the lifting equipment during the lifting and transport of building beams. This effectively improves the stability of the lifting equipment and prevents it from sliding and shifting during the process, which could cause the building beam to lose balance and stability, sway and swing, or cause the wire rope and hook to loosen and come off easily, making the building beam prone to falling from a height. This helps to improve the safety of building beam lifting operations. Attached Figure Description

[0031] Please refer to Figures 1 to 5 Example 1:
[0032] This embodiment proposes a quick-connect prefabricated building beam, including a building beam 1, with two symmetrically arranged T-shaped track grooves 1022 embedded in the top of the building beam 1;
[0033] The T-shaped track groove 1022 has an internal T-shaped track groove 1022. Two rectangular slide plates 2 are slidably installed in the horizontal part of the bottom side of the T-shaped track groove 1022. Two vertical support plates 201 are symmetrically welded to the top of the rectangular slide plates 2. Rectangular rod sleeves 3 are welded to the top of the two vertical support plates 201. A lifting plate 4 is slidably installed through the rectangular rod sleeve 3. Two limiting blocks 403 are symmetrically integrally formed at the bottom part of the lifting plate 4. A lifting ring 402 is integrally formed at the top of the lifting plate 4. The top of the rectangular slide plate 2 is symmetrically provided with Two rows of friction positioning teeth 202 are provided. When the rectangular slide plate 2 is hoisted upward, the two rows of friction positioning teeth 202 press against the two top walls of the horizontal part of the T-shaped track groove 1022. An installation ear block 2011 is welded to the outside of a vertical support plate 201. A tightening bolt 2012 is threaded through the installation ear block 2011. The bottom end of the tightening bolt 2012 presses against the bottom wall of the T-shaped track groove 1022, and its top end is fixedly connected to a tension cap with a hexagonal insertion hole inside.
[0034] Preferably, the two narrow sides of the suspension plate 4 are integrally formed with two vertical sliding strips 401.
[0035] Preferably, two vertical guide grooves 2013 are symmetrically provided on the inner side of the vertical support plate 201, and two vertical slide bars 401 are slidably engaged with the two vertical guide grooves 2013.
[0036] Preferably, the vertical guide groove 2013 extends upward and passes through the rectangular sleeve 3.
[0037] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:
[0038] Two reinforcing strips 1021 are symmetrically welded on both sides of the track 102. The two reinforcing strips 1021 are cast and inserted into the top part of the building beam 1. The building beam 1 has a trapezoidal frame structure, and two rows of through assembly holes 101 are symmetrically arranged on its two inclined side plates. The bottom part of the suspension plate 4 is slidably connected to the vertical part of the T-shaped track groove 1022.
[0039] The following section provides a detailed explanation of the working principles, specific details, implementation steps, functions and interrelationships of each feature, and their roles in realizing this technical solution:
[0040] The building beam 1 is hoisted using four steel wire ropes connected to the hoisting equipment at their tail ends. The hooks at the beginning of the four steel wire ropes are respectively hooked to four lifting rings 402. During hoisting, the four rectangular sliding plates 2 and the lifting rings 402 need to be adjusted to a symmetrical position with reference to the centerline of the building beam 1 along its length (refer to...). Figure 1(); Through the four rectangular sliding plates 2, the four lifting rings 402 can slide relative to each other along the two tracks 102 to adjust the distance between them, which facilitates the adjustment of the lifting angle of the four wire ropes to carry out the centered and stable lifting of the building beam 1.
[0041] When the tightening bolt 2012 presses against the bottom wall of the T-shaped track groove 1022, the rectangular slide plate 2 and the lifting ring 402 can be tightened and positioned in the sliding adjustment position. When sliding the lifting ring 402, the tightening bolt 2012 needs to be rotated to push its bottom end away from the bottom wall of the T-shaped track groove 1022, thus loosening the rectangular slide plate 2. Before the lifting operation begins and the wire rope is not yet taut, the tightening bolt 2012 can use its tightening and positioning effect to position the lifting device composed of the rectangular slide plate 2, the lifting plate 4, and the lifting ring 402, preventing the lifting device from being in this state. Lacking necessary positioning, the wire rope was pulled and displaced by the subsequent straightening of the steel cable, causing the intended sliding and adjustment position to be disordered, affecting the smooth lifting of the building beam 1. At the start of the lifting operation, the steel cable was gradually straightened. When the steel cable was straightened, it began to lift the lifting ring 402 and the lifting plate 4 upward through the hook at its first end. When the two limiting blocks 403 slid upward with the lifting plate 4, they came into contact with the rectangular rod sleeve 3. When the two limiting blocks 403 came into contact with the rectangular rod sleeve 3, the lifting force of the steel cable was transferred to the rectangular rod sleeve 3, and then transferred by the rectangular rod sleeve 3 and the two vertical support plates 2. 01. The lifting force continues to be transferred to the rectangular slide plate 2. When the lifting force is transferred to the rectangular slide plate 2, the wire rope can lift the building beam 1 through the rectangular slide plate 2. During the above process, when the lifting force is transferred to the rectangular slide plate 2, a pulling force is generated on the rectangular slide plate 2, causing it to slide upward. Under the action of this force, the two rows of friction positioning teeth 202 are pressed against the two top walls of the horizontal part of the T-shaped track groove 1022. In this state, the two friction positioning teeth 202 can exert the squeezing friction between themselves and the two top walls to lift the rectangular slide plate 2 and the lifting beam 1. The lifting device is positioned so that the tightening bolts 2012 can still position the lifting device during the lifting and transport of the building beam 1. In this way, the two rows of friction positioning teeth 202 and the tightening bolts 2012 work together to perform double positioning of the lifting device twice during the lifting and transport of the building beam 1. This can effectively improve the fixing stability of the lifting device and prevent the lifting device from sliding and shifting during the above process, which would cause the building beam 1 to lose balance and stability, sway and swing, and cause the wire rope and hook to easily loosen and disengage, making the building beam 1 prone to falling from a height. This helps to improve the safety of the lifting operation of the building beam 1.
[0042] The two building beams 1 that need to be assembled together can be quickly connected and assembled through the two rows of through assembly holes 101 set on them. The specific operation steps are as follows: when the two building beams 1 are joined together, the four rows of through assembly holes 101 on them are aligned and located on the same axis, and are connected to form two rows of long assembly shaft holes. At this time, the two rows of long connecting shafts with threads at both ends are inserted through the two rows of long assembly shaft holes. Then, lock nuts are screwed on both ends of the connecting shaft in sequence. Then, the lock nuts are locked on the opposite ends of the two building beams 1 in sequence. In this way, the connection and assembly of the two building beams 1 can be completed.
