Description

Technical Field

[0001] This application relates to the field of prestressing tensioning technology, and in particular to a prestressing tensioning fixing bracket for cast-in-place beams. Background Technology

[0002] Prestressing tensioning is the process of applying tension to a structural member in advance, causing the member to bear compressive stress and thus deform to cope with the loads on the structure itself, including the weight of the member, wind load, snow load, seismic load, etc.

[0003] Chinese utility model patent CN207862788U discloses a tensioning jack hoisting device connected to a suspended irrigation basket, including a chain hoist, a bracket, a longitudinal roller assembly, and a transverse roller assembly. The longitudinal roller assembly includes a transverse track and longitudinal rollers symmetrically connected to its upper ends. The transverse roller assembly includes a mounting frame and transverse rollers connected to its upper end. There are two brackets symmetrically connected to the front end of the main truss of the suspended irrigation basket, and the lower end of the bracket is a horizontally arranged longitudinal track. The longitudinal rollers are movably connected to the longitudinal track, and the transverse track is located below the longitudinal track. The transverse rollers are movably connected to the transverse track. The upper end of the chain hoist is hooked to the mounting frame, and the lower end is hoisted with the tensioning jack via a hook and a wire rope.

[0004] The aforementioned patent reduces the difficulty of assembling and disassembling tension jacks and improves safety. However, it connects to the main truss via a hinged seat, which can damage the main truss and makes it difficult to adjust the ceiling device. Utility Model Content

[0021] Example This embodiment provides a prestressed tensioning and fixing bracket for cast-in-place beams, such as... Figure 1 and Figure 2 As shown, the device includes a sliding assembly 1000. The top of the sliding assembly 1000 is provided with a crossbeam connecting frame 2000 and a truss connecting frame 3000 for connection with the hanging basket. The crossbeam connecting frame 2000 is located at one end of the sliding assembly 1000, with one end fixed to the sliding assembly 1000 and the other end connected to the top of the front upper crossbeam. The truss connecting frame 3000 is located at the other end of the sliding assembly 1000, with one end detachably connected to the sliding assembly 1000 and the other end connected to the top of the truss.

[0022] The sliding assembly 1000 abuts against the top of the hanging basket through the crossbeam connecting frame 2000 and the truss connecting frame 3000. It maintains stability through its own weight and the connection between the hanging basket and itself. The horizontality of the connection part with the hanging basket and itself can be adjusted by adjusting the crossbeam connecting frame 2000 and the truss connecting frame 3000.

[0023] In this embodiment, the sliding assembly 1000 includes a longitudinal slide rail 1100 and a transverse slide rail 1200. A pair of longitudinal slide rails 1100 are arranged side by side with a gap between them. The transverse slide rail 1200 is slidably connected to the longitudinal slide rail 1100 through a longitudinal pulley. The transverse slide rail 1200 is provided with a transverse pulley.

[0024] The top of the end of the longitudinal slide rail 1100 is connected to the crossbeam connecting frame 2000 and the truss connecting frame 3000 respectively. The upper part of the transverse slide rail 1200 is slidably connected to the lower part of the longitudinal slide rail 1100 through the longitudinal pulley. The transverse slide rail 1200 can slide along the length direction of the longitudinal slide rail 1100. The lower part of the transverse slide rail 1200 is provided with a transverse pulley, which can slide along the length direction of the transverse slide rail 1200.

[0025] In this embodiment, a lifting assembly for hoisting the tensioning equipment is connected to the lower part of the transverse pulley.

[0026] In this embodiment, the crossbeam connecting frame 2000 includes a first crossbar 2100 and a first longitudinal bar 2200. The first longitudinal bar 2100 is disposed at the end of the first crossbar 2200, with one end fixedly connected to the first crossbar 2100 and the other end fixedly connected to the longitudinal slide rail 1100.

[0027] The crossbeam connecting frame 2000 has an overall portal-shaped structure. Its upper part is used to connect with the front upper crossbeam, and its lower part is fixed to the longitudinal slide rail 1100.

[0028] In this embodiment, the truss connector 3000 includes a second crossbar 3100 and a screw 3200. A pair of second crossbars 3100 are arranged side by side with a gap between them, and the screw 3200 is disposed at the end of the second crossbar 3100 for connecting the pair of second crossbars 3100 and detachably connecting them to the truss.

[0029] A pair of second crossbars 3100 are provided on the upper and lower sides of the truss and are connected to each other by screws 3200. The spacing between the pair of second crossbars 3100 can be adjusted by screws 3200. The second crossbars 3100 located below the truss are detachably connected to the longitudinal slide rails 1100 by screws 3200, which can enhance the stability of the pair of longitudinal slide rails 1100. The horizontality of the sliding component 1000 can also be adjusted by adjusting the spacing between the pair of second crossbars 3100.

[0030] The sliding assembly 1000 is suspended on the top of the basket via the crossbeam connecting frame 2000 and the truss connecting frame 3000, providing sufficient stability while facilitating adjustment.

[0031] In this embodiment, a pad 4000 is provided between the upper second crossbar 3100 and the truss to facilitate better truss connection. The pad 4000 with different inclinations can also be replaced to adapt to trusses with different inclinations, thus enhancing the applicability of the tensioning and fixing bracket.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
