Description

Technical Field

[0001] This utility model relates to the field of steel cage binding structure technology, specifically to a prefabricated T-beam web reinforcement installation and positioning jig. Background Technology

[0002] The web of a T-beam is the main load-bearing structure of the entire T-beam, formed by pouring concrete onto the web reinforcement cage. Traditional T-beam web reinforcement installation and positioning jigs are integral, which are inconvenient to disassemble and reuse, limiting their adaptability to the installation and positioning of web reinforcement for T-beams of different lengths and resulting in poor versatility.

[0003] Patent publication number "CN208052253U" discloses a positioning jig for prefabricating T-beam web reinforcement cages, an installation platform, several sets of transverse reinforcement positioning components spaced at intervals on any one of the upper edges of the installation platform, and two sets of vertical reinforcement positioning components arranged parallel to the upper surface of the installation platform. Each set of transverse reinforcement positioning components includes a vertical fixing rod and several horizontal support rods. The bottom of the vertical fixing rod is connected to the installation platform, and one end of each horizontal support rod is vertically mounted on the vertical fixing rod, while the other end extends into the space above the installation platform. The transverse reinforcement of the T-beam web is inserted into each horizontal support rod. Each set of vertical reinforcement positioning components includes several toothed plates arranged sequentially, with the gap between adjacent toothed plates in the same set used to place the longitudinal reinforcement of the T-beam web. This patent's T-beam web vertical reinforcement cage installation only positions the vertical reinforcement at the bottom, resulting in fewer positioning points and problems such as inaccurate positioning of the upper reinforcement and easy deformation of the reinforcement.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] This utility model relates to a prefabricated T-beam web reinforcement installation and positioning jig, used for positioning and binding reinforcement cages. Its support frame 1 can be connected to the connecting longitudinal beams 7 of adjacent support frames 1 through frame connecting clamps 2, which can improve stability and facilitate flexible adjustment of the longitudinal length of the positioning jig. The transverse clamps 3 are vertically spaced on the support frame 1, and can slide to adjust the extension of the sleeved vertical reinforcement positioning component 4 and achieve locking, forming multiple positioning points in the vertical direction, avoiding the problems of inaccurate positioning and easy deformation of the upper part of the reinforcement, and facilitating the lifting of the reinforcement cage by sliding the vertical reinforcement positioning component 4 after binding. The longitudinal reinforcement positioning component 5 is inserted into the transverse insertion hole to support the longitudinal reinforcement 9, and at the same time facilitates the lifting of the reinforcement cage after sliding. The overall structure is simple, and the modular design facilitates flexible disassembly, adjustment of the extension and longitudinal length of the positioning jig, and is easy to use.

[0045] A prefabricated T-beam web reinforcement installation and positioning jig, specifically, as follows: Figure 1-5As shown, the system includes multiple support frames 1, frame connecting clamps 2, transverse clamps 3, vertical rib positioning components 4, and longitudinal rib positioning components 5. The multiple support frames 1 are spaced apart longitudinally, and each support frame 1 has multiple transverse insertion holes spaced apart vertically. The frame connecting clamps 2 are fixed to the support frames 1 and are used to engage the connecting longitudinal beams 7 of adjacent support frames 1. The transverse clamps 3 are spaced apart vertically and fixed to the support frames 1. Each transverse clamp 3 includes a transverse outer tube 31 and an adjusting fastener that inserts into the transverse outer tube. The adjusting fastener is used for… The vertical reinforcement positioning component 4 is engaged with the horizontal outer tube 31 after it slides to the set position. One end of the vertical reinforcement positioning component 4 is laterally slidably sleeved inside the horizontal outer tube 31. The end of the vertical reinforcement positioning component 4 extending out of the horizontal outer tube 31 has multiple positioning grooves (421, 441) spaced longitudinally. The vertical reinforcement positioning component 4 slides inside the horizontal outer tube 31 and is secured by tightening the first bolt 32. The longitudinal reinforcement positioning component 5 is laterally inserted into the horizontal insertion hole to receive the longitudinal reinforcement 9. Preferably, the adjusting fastener includes a threaded first bolt 32 that passes through the horizontal outer tube 31. After the vertical reinforcement positioning component 4 slides to the set position, the first bolt 32 is tightened to secure the vertical reinforcement positioning component 4. The structure is simple and easy to use.

[0046] In one embodiment, such as Figure 1-2 As shown, since the bottom of the vertical reinforcement 8 is a horseshoe-shaped reinforcement arranged horizontally and along the vertical direction, the vertical reinforcement positioning component 4 is set at the bottom of the support frame 1 to position the horseshoe reinforcement. In order to facilitate the positioning of the horseshoe reinforcement, the vertical reinforcement positioning component 4 is different from the upper structure when it is located at the bottom of the support frame 1. The vertical reinforcement positioning component 4 includes a bottom positioning component and an upper positioning component located above the bottom positioning component. That is, the vertical reinforcement positioning component 4 is a bottom positioning component when it is located at the bottom of the support frame 1, and an upper positioning component when it is located above the bottom positioning component. The bottom positioning component includes a sliding bottom rod 43 that is slidably set in the horizontal outer tube 31 and multiple bottom longitudinal positioning plates 44 that are horizontally spaced on the sliding bottom rod 43. The top of the multiple bottom longitudinal positioning plates 44 is longitudinally spaced and has corresponding vertical positioning grooves 441 in the horizontal direction. That is, the vertical positioning grooves 441 of the multiple bottom longitudinal positioning plates 44 are corresponding in the horizontal direction and are adapted to insert the same horseshoe reinforcement. The vertical reinforcement positioning component 4 is located at the bottom of the support frame 1 as a bottom positioning component. The extension amount can be adjusted by sliding the bottom rod 43 in the transverse outer tube 31. The vertical positioning grooves 441 of the multiple bottom longitudinal positioning plates 44 are adapted to the positioning clips of the bottom horseshoe steel bars to improve positioning accuracy.

[0047] Based on the bottom positioning component, including the bottom longitudinal positioning plate 44, such as Figure 1As shown, the bottom longitudinal positioning plate 44 includes a horizontal plate and a vertical plate, both running longitudinally. The horizontal plate is fixed to the sliding bottom rod 43, and the vertical plate is fixed to the horizontal plate and has a vertical positioning groove 441 with a top opening. The horizontal and vertical plates are integrally formed into an L-shaped structure, which has higher strength and better stability. The vertical positioning grooves 441 are evenly spaced longitudinally to ensure consistent spacing of the vertical reinforcing bars 8. Preferably, the sliding bottom rod 43 is a rectangular rod, such as a square tube, which has a larger mounting surface. The horizontal plate of the bottom longitudinal positioning plate 44 can expand the connection surface with the sliding bottom rod 43, improve the connection strength, and at the same time, it is easy to form the vertical positioning groove 441 to engage the horseshoe-shaped reinforcing bars.

[0048] When the vertical rib positioning component 4 is the upper positioning part, such as Figure 1 and Figure 4 As shown, the upper positioning component includes a transverse inner rod 41 slidably disposed within the transverse outer tube 31 and an upper longitudinal positioning plate 42 fixed to one end of the transverse inner rod 41. The upper longitudinal positioning plate 42 has transverse positioning grooves 421 spaced longitudinally on the side away from the transverse inner rod 41; the transverse positioning grooves 421 are evenly spaced longitudinally. The upper positioning component has a simple structure. It is slidably inserted into the transverse outer tube 31 via the transverse inner rod 41, and a locking mechanism is achieved with the adjustment and fixing components. The upper longitudinal positioning plate 42 facilitates the formation of the transverse positioning grooves 421 for positioning and inserting the vertical reinforcing bars 8, thus improving positioning accuracy.

[0049] Based on the upper positioning component including the upper longitudinal positioning plate 42, such as Figure 1 As shown, the upper longitudinal positioning plate 42 includes an L-shaped corner plate. One side of the corner plate is fixed to the end of the transverse inner rod 41, and the other side is longitudinally spaced with transverse positioning grooves 421. The transverse positioning grooves 421 correspond to the vertical positioning grooves 441 in the vertical direction. The upper longitudinal positioning plate 42 includes an L-shaped corner plate, which can expand the connection surface with the transverse inner rod 41, improve the connection strength, and at the same time facilitate the formation of transverse positioning grooves 421 for inserting and positioning vertical reinforcing bars 8.

[0050] In a preferred embodiment, to improve the consistency of the protrusion amount of the vertical positioning component extending from the support frame 1, such as... Figure 5 As shown, a scale 411 is provided on the transverse inner rod 41 along the transverse direction to facilitate accurate adjustment of the extension amount of the upper longitudinal positioning plate 42. Optionally, a scale 411 is also provided on the sliding bottom rod 43 along the transverse direction.

[0051] In some embodiments, such as Figure 3 As shown, the longitudinal reinforcement positioning assembly 5 includes a connecting vertical rod 51 and vertically spaced supporting horizontal rods 52 on the connecting vertical rod 51. Multiple supporting horizontal rods 52 are adapted to be inserted into multiple transverse insertion holes. The longitudinal reinforcement positioning assembly 5 has a simple structure. By fixing multiple supporting horizontal rods 52 to the connecting vertical rod 51, multiple supporting horizontal rods 52 can be inserted simultaneously, improving construction efficiency.

[0052] In one embodiment, such as Figure 1-2 As shown, the frame connecting clamp 2 includes a longitudinal outer tube 21 and a second bolt 22 threadedly connected to and inserted into the longitudinal outer tube 21. When the connecting longitudinal beam 7 passes through the longitudinal outer tubes 21 of multiple supporting frames 1, tightening the second bolt 22 secures the connecting longitudinal beam 7 against the longitudinal outer tube 21, facilitating assembly and disassembly. Preferably, the longitudinal outer tube 21 has two threaded holes spaced longitudinally, each threaded with a second bolt 22, facilitating the clamping of two connecting longitudinal beams 7 by the two second bolts 22. In actual use, multiple frame connecting clamps 2 are provided on the supporting frame 1 to form multiple connection points, and multiple connecting longitudinal beams 7 are longitudinally connected to the supporting frame 1 at multiple connection points, resulting in higher stability.

[0053] In one embodiment, such as Figure 1-2 As shown, the support frame 1 includes two vertical beams 11 and multiple connecting beams 12 that are fixed to the two vertical beams 11 at both ends. The frame connecting clamps 2 are provided on the two vertical beams 11 to form multiple connection points. The longitudinally adjacent support frames 1 are connected by connecting beams 7 to improve stability.

[0054] The supporting frame 1 includes two vertical beams 11 and a connecting horizontal beam 12, such as Figure 1-2 As shown, the vertical beam 11 is fixed with transverse sleeves 6 at intervals in the vertical direction, and the internal channels of the transverse sleeves 6 form the aforementioned transverse insertion holes. By fixing the transverse sleeves 6 to the vertical beam 11 to form transverse insertion holes, no drilling is required, which makes it easy to form transverse insertion holes and ensures the strength of the vertical beam 11.

[0055] In actual use, two vertical beams 11 are fixedly connected by multiple connecting horizontal beams 12 to form a support frame 1. Multiple frame connecting clamps 2 are welded to the connecting vertical beams 11. Multiple support frames 1 are connected by connecting longitudinal beams 7 passing through and clamping longitudinal outer tubes 21. Multiple transverse clamps 3 are vertically spaced on the same vertical beam 11 and extend outward. Both the top and bottom ends of the vertical beam 11 are provided with transverse clamps 3. The sliding bottom rod 43 is laterally slidably sleeved in the transverse outer tube 31 at the bottom end and clamped by the first bolt 32. Two L-shaped bottom longitudinal positioning plates 44 are laterally spaced and fixed on the sliding bottom rod 43. The top of the bottom longitudinal positioning plate 44 is provided with a vertically open vertical positioning groove 441. The upper positioning component is slidably connected in the transverse outer tube 31 through the transverse inner rod 41 and clamped by the corresponding first bolt 32. Angle plates are welded to the end of the transverse inner rod 41 and are provided with transverse positioning grooves 421 at even intervals along the longitudinal direction, corresponding to the vertical positioning grooves 441.

[0056] This utility model adopts a modular design to facilitate flexible disassembly, adjustment of the extension amount and longitudinal length of the positioning frame. The support frame 1 is connected to the longitudinal beam 7 by the frame connecting clamp 2, which facilitates assembly, disassembly and flexible adjustment of the longitudinal length of the positioning frame. Multiple horizontal clamps 3 that slide and engage with the vertical rib positioning components 4 are provided vertically at intervals, forming multiple clamping points in the vertical direction for accurate positioning.
