Description

Technical Field

[0001] The invention relates to the technical field of embedded parts, and in particular to a tensile embedded part. Background Art

[0002] Embedded parts (prefabricated embedded parts) are components pre-installed (buried) in concealed projects. They are components placed during structure casting and are used for overlap when building superstructures to facilitate the installation and fixation of external engineering equipment foundations. Embedded parts are mostly made of metal. Among them, groove-type embedded parts are ideal fixing parts that are easy to install and adjustable. The embedded parts use T-bolts or toothed bolts and matching nuts and washers, and can be used to fix any structural components. The groove is embedded in the concrete and the surface is flush with the concrete.

[0003] The trough type embedded parts are generally rigidly connected to the trough body through anchor rods. One end of the anchor rod is buried in the concrete to play an anchoring role. The trough type embedded parts transfer force to the concrete through the anchor rod. However, the current trough type embedded parts have weak anchoring bearing capacity, resulting in weak tensile and shearing resistance. When there are many and heavy external components to be fastened, the connection between the anchor rod and the concrete will become loose, resulting in reduced tightness of the anchor rod. For this reason, a tensile embedded part is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the anchoring bearing capacity of the current groove-type embedded parts is weak, resulting in weak tensile and shearing capabilities. When the number of fastened external components is large and heavy, the connection between the anchor rod and the concrete will become loose, resulting in reduced fastness of the anchor rod.

[0009] Furthermore, the anti-shear component includes two anti-shear holes respectively opened on the top and bottom side walls of the anti-tension sleeve, and anti-shear bolts are inserted into the anti-shear holes, and one end of the anti-shear bolts is threaded with an anti-shear nut.

[0010] Furthermore, a shear-resistant short-long sleeve is movably sleeved on the anti-shear bolt, the anti-shear short-long sleeve is located between the anti-shear bolt head and the anti-shear nut, and the anti-shear short-long sleeve is movably inserted inside the two anti-shear holes.

[0011] Furthermore, the tensile reinforcements are all fixedly sleeved with limiting metal rings, and the interiors of the semicircular clamping grooves are all provided with semicircular limiting grooves matched with the limiting metal rings.

[0012] Furthermore, a backing plate is arranged inside the embedded slot, one end of the plurality of embedded flat head bolts respectively passes through each of the embedded holes and extends to the inside of the embedded slot, and the backing plate is movably sleeved on one end of the plurality of embedded flat head bolts.

[0014] 1. The present invention provides a tensile sleeve and tensile reinforcement, so that the tensile sleeve and tensile reinforcement buried in the concrete can increase the grip of the concrete on the embedded part, so that the tensile sleeve and tensile reinforcement play an anti-pulling role on the embedded slot, thereby improving the tensile resistance of the embedded slot.

[0019] 6. The present invention sets a limiting metal ring so that during the installation of the tensile sleeve and the tensile reinforcement, the limiting metal ring is placed in the combined semicircular limiting groove. After the tensile sleeve is locked, the limiting metal ring cooperates with the semicircular limiting groove to limit the tensile reinforcement, thereby preventing the tensile reinforcement from relatively sliding in the semicircular clamping groove and then deviating from the tensile sleeve, which affects the tensile resistance of the embedded part.

[0037] like Figures 1 to 11 As shown, a tensile embedded part includes an embedded slot 1, and one side of the embedded slot 1 is provided with a plurality of embedded holes evenly distributed from top to bottom, such as Figure 2 As shown, embedded flat head bolts 2 are inserted into the embedded holes, the heads of the embedded flat head bolts 2 are away from the embedded slots 1, and one end of the embedded flat head bolts 2 located inside the embedded slots 1 is threaded with embedded hexagonal nuts 3, and the embedded flat head bolts 2 are movably sleeved with anti-shear long sleeves 4, and one end of the plurality of anti-shear long sleeves 4 extends to the inside of the embedded holes, respectively. Figure 5 As shown, the embedded flat head bolt 2 is movably sleeved with two tensile sleeves 5, the two tensile sleeves 5 are located between the head of the embedded flat head bolt 2 and the anti-shear long sleeve 4, and one end of the tensile sleeve 5 is fixedly installed with a tensile sleeve plate 6. In this embodiment, as another assembly method, the following can be used: Fig.11 The separated small-volume tensile sleeves 6 shown replace the original complete large-volume tensile sleeves 6. The specific number and volume of the tensile sleeves 6 can be determined based on the volume of the concrete tank. Figure 6 As shown, a sleeve hole 601 connected to the tensile sleeve 5 is opened on the side wall of the tensile sleeve 6, and the two tensile sleeves 6 located on the same side are symmetrically arranged. One end of the embedded flat head bolt 2 located at the same place passes through the two sleeve holes 601 in sequence. The two tensile sleeves 6 located on the same side are close to each other. The side is opened with a plurality of semicircular clip grooves 602 evenly distributed from top to bottom, and the semicircular clip grooves 602 are all horizontally arranged. Figure 1As shown, the same tensile reinforcement 7 is clamped between the two semicircular clamping grooves 602 located on the same side, and the tensile sleeve 6 is provided with a shear-resistant component for assisting the anti-shear long sleeve 4 to improve the shear resistance of the embedded flat head bolt 2; specifically, when installing the tensile embedded part, first, a plurality of embedded flat head bolts 2 are inserted into the tensile sleeve 5 on a single tensile sleeve 6 in sequence, and then another tensile sleeve 6 is sleeved on the embedded flat head bolt 2, so that the two tensile sleeves 6 are merged, and a specified number of tensile reinforcements 7 are inserted into the semicircular clamping groove 602 between the two tensile sleeves 6, and then each anti-shear long sleeve 4 is sleeved on the embedded flat head bolt 2 in sequence, the two tensile sleeves 6 are pressed tightly, and then each anti-shear long sleeve 4 is inserted into each embedded hole on one side of the embedded slot part 1 together with the embedded flat head bolt 2, and the embedded slot is inserted into each embedded hole in the embedded slot. The embedded hexagonal nut 3 is screwed onto one end of each embedded flat-head bolt 2 inside the component 1, so that the embedded hexagonal nut 3 locks the anti-shear long sleeve 4, the tensile sleeve 5, the tensile sleeve 6 and the embedded flat-head bolt 2 on one side of the embedded slot component 1, and at the same time forces the two tensile sleeves 6 to clamp the multiple tensile reinforcements 7 to complete the assembly of the tensile sleeves 6. When in use, by setting the tensile sleeves 6 and the tensile reinforcements 7, the tensile sleeves 6 and the tensile reinforcements 7 buried in the concrete can increase the contact area between the concrete and the embedded component, increase the grip of the concrete on the embedded component, and make the tensile sleeves 6 and the tensile reinforcements 7 play an anti-pulling role on the embedded slot component 1, thereby improving the tensile resistance of the embedded slot component 1. At the same time, the number and position of the tensile reinforcements 7 can be adjusted according to actual construction conditions and engineering requirements to achieve modular adjustment of the embedded component.

[0038] like Figure 1 As shown, a U-shaped positioning rib 8 is provided on one side of the head of the embedded flat head bolt 2. Figure 7 As shown, the head of the embedded flat head bolt 2 is opened and closed with a flat opening 201, as shown in FIG. Figure 8 As shown, a positioning block 9 adapted to the flat opening 201 is fixedly installed on the side wall of the U-shaped positioning rib 8. In this embodiment, the flat opening 201 can also be replaced by a cross opening or a hexagonal inner opening commonly found on the market, and the positioning block 9 is replaced with a corresponding shape. Positioning holes 603 adapted to the U-shaped positioning rib 8 are provided on the side wall of the tension sleeve 6. The two ends of the U-shaped positioning rib 8 respectively penetrate the two positioning holes 603 in sequence and extend to one side of the embedded slot 1. Specifically, by setting the U-shaped positioning rib 8, After the installation of the tensile sleeve 6 is completed, multiple U-shaped positioning ribs 8 are placed on one side of the tensile sleeve 6 in sequence, so that the two ends of the U-shaped positioning rib 8 pass through the positioning holes 603 on the tensile sleeve 6 and abut against the back side of the embedded slot 1, and the positioning blocks 9 on the side walls of the U-shaped positioning rib 8 are inserted into the flat opening 201 of the head of the embedded flat head bolt 2, so that the U-shaped positioning rib 8 and the tensile sleeve 6 cooperate with each other to limit the embedded flat head bolt 2, thereby preventing the embedded flat head bolt 2 from rotating in the concrete and causing the threaded connection to loosen.

[0039] like Figure 1 As shown, a plurality of evenly distributed positioning cone sleeves 10 are fixedly installed on one side of the embedded slot part 1 close to the tensile sleeve 6, and the positioning cone sleeves 10 are adapted to the U-shaped positioning rib 8, and the two ends of the U-shaped positioning rib 8 on the same side are respectively inserted into the inside of the two positioning cone sleeves 10; specifically, by setting the positioning cone sleeves 10, during the installation of the U-shaped positioning rib 8, the two ends of the U-shaped positioning rib 8 will be respectively inserted into the two positioning cone sleeves 10 after passing through the positioning hole 603 and extending to the back side of the embedded slot part 1, and then the U-shaped positioning rib 8 is gently tapped in the direction of the embedded slot part 1 with a leather hammer, so that the positioning block 9 on one side of the U-shaped positioning rib 8 and the flat mouth 201 are more closely matched, and at the same time, the two ends of the U-shaped positioning rib 8 are tightly clamped in the inside of the positioning cone sleeves 10, so that the positioning cone sleeves 10 play an auxiliary limiting role for the U-shaped positioning rib 8.

[0040] like Figure 5 , Figure 6 As shown, the anti-shear assembly includes two anti-shear holes 604 respectively opened on the top and bottom side walls of the tensile sleeve 6. Figure 2 As shown, the anti-shear holes 604 are all plugged with anti-shear bolts 11. Figure 1 As shown, one end of the anti-shear bolt 11 is threaded with an anti-shear nut 12. In this embodiment, Figure 2 As shown, the screw rod of the shear bolt 11 can be directed toward the depth of the concrete, or it can be as shown in FIG. Figure 3 As shown, another assembly method is adopted, so that the screw rod of the anti-shear bolt 11 faces the embedded groove part 1, and it can also be as shown in FIG. Figure 4 As shown, the assembly method of directly inserting a metal rod or a rib into the anti-shear hole 604 is used to replace the anti-shear bolt 11 to play an anti-shear role. The specific assembly method of the anti-shear component can be selected according to the actual construction conditions; specifically, by setting the anti-shear component, after the embedded flat head bolt 2 is positioned, the anti-shear bolts 11 are inserted into the anti-shear holes 604 at the upper and lower ends of the tension sleeve 6 in sequence, and the anti-shear nuts 12 are screwed on the anti-shear bolts 11 to fix the anti-shear bolts 11 on the tension sleeve 6, so that the anti-shear bolts 11 and the embedded flat head bolts 2 are kept in a parallel state, and the embedded flat head bolts 2 are respectively played with the role of sharing the load from the upper and lower sides. The anti-shear bolts 11 and the anti-shear long sleeves 4 on the embedded flat head bolts 2 replace the embedded flat head bolts 2 to bear the vertical shear force of the embedded part after embedding, thereby improving the anti-shear ability of the embedded part.

[0041] like Fig.10As shown, a shear-resistant short-long sleeve 13 is movably sleeved on the anti-shear bolt 11, and the shear-resistant short-long sleeve 13 is located between the head of the anti-shear bolt 11 and the anti-shear nut 12, and the shear-resistant short-long sleeve 13 is movably inserted into the two anti-shear holes 604; specifically, by providing the anti-shear short-long sleeve 13, before the anti-shear bolt 11 is screwed onto the tension sleeve 6, the shear-resistant short-long sleeve 13 can be sleeved on the anti-shear bolt 11, so that the shear-resistant short-long sleeve 13 is against one side of the head of the anti-shear bolt 11, and then the anti-shear bolt 11 is inserted into the anti-shear hole 604, so that the shear-resistant short-long sleeve 13 replaces the anti-shear bolt 11 and is inserted into the anti-shear hole 604, and then the anti-shear nut 12 is screwed onto the anti-shear bolt 11, and the anti-shear nut 12 is tightened, so that the shear-resistant short-long sleeve 13 replaces the anti-shear bolt 11 to withstand the shear force of the tension sleeve 6 on the anti-shear bolt 11, thereby improving the shear resistance of the anti-shear bolt 11 itself.

[0042] like Fig. 9 As shown, the tensile reinforcement 7 is fixedly sleeved with a limited metal ring 14. Figure 6 As shown, the interior of the semicircular clamping groove 602 is provided with a semicircular limiting groove 605 which is compatible with the limiting metal ring 14; specifically, by setting the limiting metal ring 14, when preparing the tensile reinforcement 7, the limiting metal ring 14 which is compatible with the semicircular limiting groove 605 on the tensile sleeve 6 can be welded on the tensile reinforcement 7, and then in the process of installing the tensile sleeve 6 and the tensile reinforcement 7, the limiting metal ring 14 is placed in the combined semicircular limiting groove 605. After the tensile sleeve 6 is locked, the limiting metal ring 14 cooperates with the semicircular limiting groove 605 to limit the tensile reinforcement 7, thereby preventing the tensile reinforcement 7 from relative slipping in the semicircular clamping groove 602, and then offsetting from the tensile sleeve 6, resulting in the tensile resistance of the embedded part being affected.

[0043] like Figure 2 As shown, a gasket 15 is provided inside the embedded slot part 1, and one end of a plurality of embedded flat-head bolts 2 respectively penetrates each embedded hole and extends to the inside of the embedded slot part 1, and the gasket 15 is movably sleeved on one end of the plurality of embedded flat-head bolts 2; specifically, by providing the gasket 15, before the embedded hexagonal nut 3 is screwed on the embedded flat-head bolt 2 for locking, the gasket 15 can be inserted into the embedded slot part 1, and then the gasket 15 can be sleeved on one end of the plurality of embedded flat-head bolts 2, and then the embedded hexagonal nut 3 is screwed on the embedded flat-head bolt 2, and the anti-shear long sleeve 4, the tensile sleeve 6, the tensile reinforcement 7 and the gasket 15 are locked together, and the gasket 15 can play a role of padding between the embedded slot part 1 and the embedded hexagonal nut 3, and at the same time, the matching gap between the anti-shear long sleeve 4 and the embedded hole on the embedded slot part 1 is covered to play a role of moisture-proof and dust-proof.

[0044] In summary: Installation of the tensile member: first, insert a plurality of pre-embedded flat-head bolts 2 into the tensile sleeve 5 on a single tensile sleeve 6 in sequence, then sleeve another tensile sleeve 6 onto the pre-embedded flat-head bolt 2, merge the two tensile sleeves 6, and insert a specified number of tensile bars 7 into the semicircular groove 602 between the two tensile sleeves 6, then sleeve each anti-shear long sleeve 4 onto the pre-embedded flat-head bolt 2 in sequence, press the two tensile sleeves 6 together, and then insert each anti-shear long sleeve 4 together with the pre-embedded flat-head bolt 2 into each of the pre-embedded slots 1 on one side. The embedded holes are inserted into the backing plate 15, and then the backing plate 15 is sleeved on one end of the multiple embedded flat head bolts 2, and then the embedded hexagonal nuts 3 are screwed on the embedded flat head bolts 2, and the anti-shear long sleeve 4, the tensile sleeve 6, the tensile reinforcement 7 and the backing plate 15 are locked together, so that the embedded hexagonal nuts 3 lock the anti-shear long sleeve 4, the tensile sleeve 5, the tensile sleeve 6 and the embedded flat head bolts 2 on one side of the embedded slot 1, and at the same time force the two tensile sleeves 6 to clamp the multiple tensile reinforcements 7, and complete the assembly of the tensile sleeve 6;

[0045] Positioning of flat head bolts: After the installation of the tension sleeve 6 is completed, multiple U-shaped positioning ribs 8 are placed on one side of the tension sleeve 6 in sequence, so that the two ends of the U-shaped positioning rib 8 pass through the positioning holes 603 on the tension sleeve 6 and abut against the back side of the embedded slot 1, and are respectively inserted into the two positioning cone sleeves 10, and then the U-shaped positioning rib 8 is gently knocked in the direction of the embedded slot 1 with a leather hammer, so that the positioning block 9 on one side of the U-shaped positioning rib 8 and the flat mouth 201 are more tightly matched, and at the same time, the two ends of the U-shaped positioning rib 8 are tightly clamped in the interior of the positioning cone sleeve 10, and the positioning block 9 on the side wall of the U-shaped positioning rib 8 is clamped in the flat mouth 201 of the head of the embedded flat head bolt 2, so that the U-shaped positioning rib 8 and the tension sleeve 6 cooperate with each other to limit the embedded flat head bolt 2, so as to prevent the embedded flat head bolt 2 from rotating in the concrete, resulting in loosening of the threaded connection;

[0046] Installation of the anti-shear component: insert the anti-shear bolts 11 into the anti-shear holes 604 at the upper and lower ends of the tensile sleeve 6 in sequence, sleeve the anti-shear short and long sleeves 13 on the anti-shear bolts 11, make the anti-shear short and long sleeves 13 rest against one side of the head of the anti-shear bolt 11, and then insert the anti-shear bolt 11 into the anti-shear hole 604, make the anti-shear short and long sleeves 13 replace the anti-shear bolt 11 and be plugged into the anti-shear hole 604, then screw the anti-shear nut 12 on the anti-shear bolt 11, tighten the anti-shear nut 12, and fix the anti-shear bolt 11 on the tensile sleeve 6, so that the anti-shear bolt 11 and the embedded flat head bolt 2 remain parallel.
