Specific embodiments

[0033] To make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0034] Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0035] Second, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments.

[0036] Embodiment 1

[0037] Referring to Figures 1 to 3 , which is the first embodiment of the present invention. This embodiment provides a pre-embedded nut component for wall tie bars in a frame structure. The pre-embedded nut component for wall tie bars in the frame structure includes a plugging component 100, an expansion bolt component 200, and a limiting and plugging component 300. Through the plugging component 100, an expansion bolt can be installed in a template hole on a wall column template. After the template is removed, by the expansion bolt component 200, the end of the wall tie bar is threaded or a through-threaded screw rod is used and inserted into the pre-embedded nut of the wall tie bar and tightened, thereby replacing the wall tie bar using the rebar planting method. Through the limiting and plugging component 300, the expansion bolt component 200 can be limited on the plugging component 100, playing a role of limiting and preventing disengagement.

[0038] Specifically, the plugging component 100 includes a silicone plugging member 101. The silicone plugging member 101 is made of 20-degree food-grade silicone and has a certain softness. It can fix the bolt member 102 well and ensure that the plugging is easy to pass through the template hole during form removal.

[0039] The bolt member 102 is movably connected inside the silicone plugging member 101. Through the setting of the bolt member 102, when the entire plugging component 100 is inserted into the hole on the template, it can play a role of supporting and positioning the expansion bolt component 200.

[0040] After the concrete is poured and solidified, when the expansion bolt component 200 can be located in the concrete and the plugging component 100 is removed, the expansion bolt component 200 will not be taken out of the concrete together. Furthermore, the end of the subsequent wall tie bar can be threaded or a through-threaded screw rod can be screwed into the threaded part of the expansion bolt component 200.

[0041] Specifically, the expansion bolt component 200 is sleeved on the surface of the bolt member 102 and includes an expansion member 201 sleeved on the surface of the bolt member 102. Through the expansion member 201, the entire expansion bolt component 200 can be stably fixed in the concrete after pouring and solidification and will not rotate when the plugging component 100 is disassembled and removed.

[0042] A pulling head part 202 is sleeved on the surface of the bolt part 102. One end of the pulling head part 202 is inserted into the expansion part 201. Through the setting of the pulling head part 202, after the plugging component 100 is disassembled and removed from the expanding bolt component 200, the end of the wall tie bar is threaded or a through-thread screw is screwed in. When it is pulled outward, the expansion sleeve 201a can be expanded and fixed, so that the pulling force is greatly improved and the strength is increased.

[0043] Specifically, the limit plugging component 300 is installed on the bolt part 102 and includes a groove body 301 opened in the bolt part 102. A transmission part 302 is installed in the groove body 301. The transmission part 302 can act on the block 304. When the bolt part 102 needs to be unscrewed, the block 304 moves in the groove body 301 without affecting its normal disassembly.

[0044] One end of the transmission part 302 is fixedly connected with a stop block 303 and is located inside the bolt part 102. A block 304 is slidably connected to the bolt part 102 and is installed on the transmission part 302. Usually, when the production and assembly of the wall tie bar embedded nut embedded component are completed, the block 304 is located on one side of the expanding head 202b of the expanding bolt to limit the expanding bolt component 200 to prevent it from detaching from the bolt part 102, which affects the normal embedding operation and causes the wall tie bar embedded nut to not function after pouring, so that it cannot be connected to the wall tie bar or the through-thread screw.

[0045] The block 304 is provided with an inclined surface. During production and assembly, and with the cooperation of the first spring 302f, it can move under extrusion, and then the bolt part 102 can pass through the silicone plugging part 101, the expansion part 201 and the pulling head part 202 smoothly and be threadedly connected to the pulling head part 202. After the extrusion is lost, it resets to limit the expanding bolt component 200 in the plugging component 100, playing an anti-detachment function.

[0046] On the one hand, the stop block 303 functions to block the internal hexagon 102c on the bolt part 102 to prevent impurities, dirt, and even concrete from entering it, resulting in the hexagon wrench not being able to be inserted well into the internal hexagon 102c during subsequent disassembly. On the other hand, when the hexagon wrench is inserted into the internal hexagon 102c and applies pressure to it, it functions to drive the square rod 302a to move, so that the extrusion column 302b on it moves to act on the inclined block 302c, causing the block 304 to move into the groove body 301.

[0047] Embodiment 2

[0048] Refer to Figures 2 to 8 , for the second embodiment of the present invention. This embodiment is based on the previous embodiment.

[0049] Specifically, the silicone plug member 101 includes a silicone column 101a sleeved on the surface of the bolt member 102. The diameter of the silicone column 101a is 14 mm. By inserting it into the die hole on the template and making close contact with the template hole, it plays a role in fixing the entire component on the template. A silicone clamping flange 101b is provided on the silicone column 101a. Through the setting of the silicone clamping flange 101b, when the silicone plug member 101 is inserted into the template hole, it can prevent further inward insertion and avoid falling through the die hole on the template.

[0050] A first hollow part 101c and a second hollow part 101d are respectively formed on the silicone column 101a, and they are interconnected with each other and match the bolt member 102. The diameter of the first hollow part 101c is 6 mm. Through the settings of the first hollow part 101c and the second hollow part 101d, the bolt member 102 can pass through the silicone plug member 101 and be tightly combined without loosening during penetration.

[0051] The bolt member 102 includes a bolt column 102a passing through the silicone column 101a. The expansion member 201 is fixed by the bolt column 102a. Its diameter is the same as the model of the internal thread 202d on the pull head member 202 of the expansion member 201. One end of the bolt column 102a is fixedly connected with a bolt head 102b. The outer circle of the bolt head 102b is circular, and the circular outer circle does not hinder the rotation of the bolt member 102 and is located in the second hollow part 101d. An internal hexagon 102c is provided on the bolt head 102b. Through the setting of the internal hexagon 102c, when the plug assembly 100 is removed, a hexagon wrench can be inserted into it for rotation and removal.

[0052] The expansion member 201 includes an expansion sleeve 201a sleeved on the outer surface of the bolt column 102a, and one end of it is in contact with the surface of the silicone column 101a. Gill bumps 201b are fixedly connected to the outer surface of the expansion sleeve 201a. The size of the gill bumps 201b is 5 mm. They are arranged around the outer wall of the expansion sleeve 201a, with four in one circle and a total of three circles, increasing the friction between the surface of the expansion sleeve 201a and the concrete contact surface.

[0053] The expansion casing 201a is respectively provided with expansion slots 201c and pull head locking holes 201d. The expansion slots 201c communicate with the pull head locking holes 201d. Four expansion slots 201c and four pull head locking holes 201d are provided on the expansion casing 201a, and they surround the outer wall of the expansion casing 201a. Through the setting of the expansion slots 201c, when the pull head 202a is pulled outwards, the expansion casing 201a can be expanded accordingly, playing a role in stably fixing in the concrete, improving the tensile strength. And the length of the slots is half of the length of the expansion casing 201a. Through the setting of the pull head locking holes 201d, the anti-rotation locking points 202c on the pull head 202a can be locked in, playing a role in fixing the pull head member 202.

[0054] An anti-rotation hole 201e is provided on the surface of one end of the expansion casing 201a and penetrates through the expansion casing 201a. The anti-rotation hole 201e is arranged at the head of the expansion casing 201a. After the concrete is poured, the concrete flows into the hole. After the concrete solidifies, it can prevent the expansion casing 201a from rotating. Reinforcing grooves 201f are provided on the expansion casing 201a, and the reinforcing grooves 201f are arranged at the head of the expansion casing 201a, which can increase the planar rigidity of the expansion casing 201a and ensure that the head of the expansion casing 201a does not deform.

[0055] The pull head member 202 includes a pull head 202a sleeved on the outer surface of the bolt column 102a and located inside the expansion casing 201a. Through the setting of the pull head 202a, the pull head member 202 can be sleeved on the surface of the bolt member 102 for fixation. One end of the pull head 202a is fixedly connected with a pull head expansion head 202b and sleeved on the surface of the bolt column 102a. Through the setting of the pull head expansion head 202b, when the pull head 202a is pulled outwards, it applies force to the expansion casing 201a. Under the action of the expansion slots 201c, the expansion casing 201a is expanded accordingly, playing a role in fixing and anti-disengagement, and improving the tensile strength.

[0056] An anti-rotation locking point 202c is fixedly connected to the outer surface of the pull head 202a and is located inside the pull head locking hole 201d. The number of anti-rotation locking points 202c is four and they surround the outer wall of the pull head 202a. When the pull head 202a is pulled outwards, it applies force to the expansion slots 201c on the expansion casing 201a, and then the expansion casing 201a is expanded accordingly, playing a role in fixing and anti-disengagement. An internal thread 202d is provided on the inner surface of the pull head 202a and is matched with the bolt column 102a. Through the setting of the internal thread 202d, the pull bolt assembly 200 can be fixed on the plug assembly 100. After the plug assembly 100 is removed after the pouring is completed, the end of the wall tie bar can be threaded or a through-threaded screw can be screwed in, which can replace the wall tie bar, eliminating the influence of personnel on the quality of the wall tie bar during the processes of the drilling depth, hole cleaning, glue preparation and installation and maintenance of the wall tie bar with the planted bar, and ensuring the quality of the wall tie bar.

[0057] Example 3

[0058] Reference Figures 3 to 11 , which is the third embodiment of the present invention and is based on the first two embodiments.

[0059] Specifically, the transmission member 302 includes a square rod 302a slidably connected in the groove body 301. One end of the square rod 302a extends into the inner hexagon 102c and is fixedly connected to the surface of the stopper 303. The surface of the other end of the square rod 302a is fixedly connected with an extrusion column 302b. The square rod 302a penetrates through the bolt column 102a and is slidably connected therewith. The extrusion column 302b can be pushed to move through the square rod 302a.

[0060] The clamping block 304 is fixedly connected with an inclined block 302c, and it contacts the surface of the extrusion column 302b. Through the arrangement of the inclined block 302c, when the extrusion column 302b moves to apply pressure to it, it can be smoothly extruded to push it to move, so that the clamping block 304 moves into the groove body 301, the clamping block 304 is separated from the concrete, and the plugging head assembly 100 is smoothly removed from the expanding bolt assembly 200, so that the expanding head 202b of the expanding bolt will not hinder the rotation and removal of the bolt member 102 due to the clamping block 304.

[0061] A sliding groove 302d is formed in the groove body 301, and a sliding block 302e is slidably connected therein. The sliding block 302e is fixedly connected to the clamping block 304. Through the arrangement of the sliding groove 302d and the sliding block 302e, the clamping block 304 is guided and limited. The surface of the sliding block 302e is fixedly connected with a first spring 302f, and one end thereof is fixedly connected to the inner wall of the groove body 301. When the inclined surface of the clamping block 304 is stressed and extruded to move, the clamping block 304 and the sliding block 302e move, so that the first spring 302f is compressed to generate an elastic force. When the clamping block 304 is not extruded, the sliding block 302e and the clamping block 304 are reset under the action of the rebound of the first spring 302f.

[0062] A second spring 302j is sleeved on one end of the square rod 302a close to the stopper 303, and its two ends are respectively in contact with the stopper 303 and the bolt head 102b. When the hexagon wrench is inserted into the inner hexagon 102c, the stopper 303 moves through the second spring 302j, thereby pushing the square rod 302a and the extrusion column 302b to move. At this time, the second spring 302j is compressed. When the stopper 303 is separated from the pressure, the stopper 303, the square rod 302a and the extrusion column 302b are reset under the action of the elastic force, and the stopper 303 plugs the inner hexagon 102c to prevent the entry of impurities and dirt.

[0063] A sealing ring 302g is provided between the clamping block 304 and the bolt column 102a. The sealing ring 302g is sleeved on the surface of the clamping block 304. Through the arrangement of the sealing ring 302g, when the clamping block 304 extends out of the bolt column 102a, the space between it and the bolt column 102a is sealed to prevent concrete from entering the tank body 301 during concrete pouring. A limiting groove 302h is provided in the tank body 301, and a limiting block 302i is slidably connected therein. The limiting block 302i is fixedly connected to the inclined block 302c. Through the arrangement of the limiting groove 302h and the limiting block 302i, the inclined block 302c is guided and limited, and at the same time, the force on one end of the inclined block 302c can be increased, so that the inclined block 302c will not be easily deformed when the extrusion column 302b extrudes it, enabling it to move stably.

[0064] During use, holes with a diameter of 14 mm are drilled in the column formwork. The embedded nut of the wall tie bar is inserted into the hole of the wall column formwork that has been positioned by setting out the lines and fixed on the formwork. After the concrete is poured and the formwork is removed, since the silicone plug 101 has a certain softness, it will not interfere with the removal of the formwork. After the formwork is removed, the embedded nut of the wall tie bar remains on the concrete structure.

[0065] During wall masonry, a hexagonal wrench is inserted into the internal hexagon 102c to apply force, causing the stop block 303 to move, and then pushing the square rod 302a and the extrusion column 302b to move. At this time, the second spring 302j is compressed. The extrusion column 302b extrudes and pushes the inclined block 302c to move, and then the clamping block 304 moves into the tank body 301, moving the clamping block 304 completely into the tank body 301.

[0066] Then rotate the hexagonal wrench to disassemble the plugging component 100 from the expansion bolt component 200. Then, thread the end of the wall tie bar or use a through-threaded screw rod to screw into the pulling head piece 202, which can replace the wall tie bar. After tightening, the pull-out test and wall masonry work can be carried out.

[0067] In summary, for the embedded nut of the wall tie bar, the expansion bolt is installed on the wall column formwork and embedded in the concrete of the wall column structure. Compared with the existing technology, after the formwork is removed, the end of the wall tie bar is threaded or a through-threaded screw rod is used and screwed tightly into the embedded nut of the wall tie bar to replace the wall tie bar installed by the post-inserted rebar method. The embedded nut of the wall tie bar can be closely combined with the concrete, increasing the pull-out force of the expansion bolt. The pull-out force of the M6 expansion bolt is greatly improved. The embedded nut of the wall tie bar is installed during formwork support, eliminating the influence of factors such as the drilling depth, hole cleaning, mixing of the post-inserted rebar adhesive, and shaking during installation and curing on the quality of the wall tie bar by personnel, ensuring the quality of the wall tie bar.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
