Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a prefabricated building structure. Background Art

[0002] In the current process of building industrialization development, prefabricated buildings are being widely promoted and applied as an efficient and environmentally friendly construction model. However, prefabricated buildings under the existing technical system are facing a structural challenge that needs to be solved urgently. In the current mainstream prefabricated component production process, the steel bar configuration method has a unidirectional limitation - during the prefabrication process, usually only one row of steel bars is arranged in a single direction of the component. This unidirectional steel bar configuration mode causes the prefabricated components to exhibit significant anisotropy in the spatial force system. When these prefabricated components are assembled and connected on site, the components can only provide a relatively large anisotropic characteristic in the direction of the steel bar arrangement. It has strong bending, tensile and shearing capabilities, while in other directions it mainly relies on the performance of the concrete itself to resist external forces. As we all know, concrete materials have excellent compressive properties, but their tensile, bending and shearing capabilities are relatively weak. In the directions without steel reinforcement, components are very likely to crack or even structurally damage due to tensile stress, bending moment or shear force. This uneven strength distribution makes the overall structure have obvious weak links under the action of multi-directional complex loads, especially under the action of multi-directional dynamic loads such as horizontal seismic force and wind load. The safety and durability of the structure face severe challenges.

[0003] The limitations of this unidirectional reinforcement arrangement not only affect the mechanical properties of the prefabricated components themselves, but also have a profound and systematic impact on the overall structural performance of prefabricated buildings. First, in the node connection area, due to the discontinuity and unidirectionality of the reinforcement arrangement, the node becomes the weak link in the overall structure, and stress concentration and damage are prone to occur under the action of multi-directional loads; secondly, the assembly connection between components usually requires on-site wet operations to ensure the integrity of the structure, which not only increases the construction difficulty and construction period, but also weakens the industrialization advantages of prefabricated buildings to a certain extent; thirdly, prefabricated components under the unidirectional reinforcement mode are prone to fatigue damage and crack expansion during long-term use due to insufficient strength in the non-reinforced direction, affecting the service life and safety of the structure; more importantly, under extreme load conditions, such as natural disasters such as earthquakes and typhoons, this structure with uneven strength distribution is more prone to brittle failure, making it difficult to exert the plastic deformation capacity of the material, which is not conducive to improving the disaster resistance of the structure. Summary of the Invention

[0004] The object of the present invention is to provide a prefabricated building structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an assembled building structure, comprising a wall; further comprising a reinforcing mechanism, the reinforcing mechanism comprising a plurality of vertical tubes pre-buried in the wall, each of the vertical tubes being connected to a plurality of transverse tubes, each of the transverse tubes being respectively sleeved and installed with a pull sleeve, and a pull plate being respectively installed between every two of the pull sleeves, each of the transverse tubes being respectively coaxially installed with a bidirectional sleeve, and each of the bidirectional sleeves being respectively installed with an annular disk, and each of the transverse tubes being respectively installed with an insertion block, and a plurality of the insertion blocks being respectively inserted into the annular disk, an annular groove being coaxially provided on the pull sleeve, and the annular disk being fitted into the annular groove; further comprising a fitting mechanism, the fitting mechanism comprising two side grooves provided on both sides of the wall, each of the vertical tubes being respectively connected to a lateral tube, and every two of the lateral tubes being respectively connected in the side grooves.

[0006] Preferably, the reinforcing mechanism also includes guide strips installed on the inner walls of the multiple insertion blocks, and a plurality of guide holes are opened at equal intervals on the annular disk, and the guide strips are slidably connected in the guide holes. This guide system design provides positioning guidance during the assembly process, ensuring that the rotational movement between the annular disk and the insertion block always remains on the predetermined track.

[0007] Preferably, a plurality of expansion grooves are respectively provided on the outer wall of each of the bidirectional sleeves, and a self-locking block is respectively slidably connected in each of the expansion grooves, and the plurality of self-locking blocks are respectively fitted on the inner wall of the transverse tube. This self-locking system design creates an intelligent locking mechanism. When the bidirectional sleeve moves under the action of tension, the expansion groove guides the self-locking block to expand outward and fit tightly against the inner wall of the transverse tube, forming an adaptive locking effect of "the greater the force, the tighter the locking".

[0008] Preferably, each two of the bidirectional sleeves are slidingly connected to a limiting frame, and a top spring is installed on the side of each self-locking block away from the annular disk, and multiple top springs are respectively in contact with the limiting frame. This preload system design continuously provides an outward preload force to the self-locking block through the top spring, ensuring that the self-locking block always maintains close contact with the inner wall of the transverse tube.

[0009] Preferably, threaded holes are opened in opposite directions on each two coaxially arranged bidirectional sleeves, and bidirectional solenoids are connected to the two threaded holes in opposite directions. This reverse thread design cleverly realizes the synchronous adjustment function. When the bidirectional solenoid is rotated, the bidirectional sleeves on both sides will move synchronously toward or away from the middle due to the action of the reverse threads, thereby achieving a precisely symmetrical adjustment effect.

[0010] Preferably, a plurality of fixing rods are installed at equal intervals between every two coaxially arranged bidirectional spiral tubes, and a hexagonal groove is opened in each bidirectional spiral tube. The setting of the fixing rods forms a stable supporting structure between the bidirectional spiral tubes, and the hexagonal groove also forms a grouting channel, so that the injected slurry can flow into the entire pipeline system. This multifunctional design not only meets the convenience of construction operation, but also ensures the stability of the structural connection, and also provides an ideal channel for the later grouting and curing.

[0011] Preferably, a plurality of steel bars are attached between each two of the pull plates, and the plurality of pull plates are respectively embedded in the wall. This steel bar embedded system design breaks through the limitation that traditional prefabricated buildings can only provide reinforcement in a single direction, by embedding pull plates in the wall and arranging a plurality of steel bars between the pull plates.

[0012] Preferably, the vertical pipes, lateral pipes and transverse pipes are respectively connected to each other, and the transverse pipes are connected to the two hexagonal grooves. This three-dimensional interconnected pipe network design forms a complete spatial grouting system, so that the injected slurry can flow unimpeded to various key connection points of the building structure. The interconnection of the vertical pipes, lateral pipes and transverse pipes ensures the comprehensiveness of the grouting coverage.

[0013] Preferably, a lateral strip is installed on one side of each side groove, and a lateral hole is opened on the other side of the side groove. Each side groove is respectively fitted with the lateral strip on the adjacent wall. This slot docking design realizes precise positioning and reliable connection between the walls. The convex and concave fit between the lateral strip and the lateral hole provides accurate docking guidance, ensuring that the adjacent walls can be accurately spliced ​​together.

[0014] Preferably, a guide rod is slidably connected to each of the vertical tubes. The guide rod design provides precise initial positioning and guiding functions for the assembly process. When adjacent walls are spliced, the guide rod can be inserted into the vertical tube of the corresponding wall to guide the wall to accurately dock to the designed position.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This innovative prefabricated building structure overcomes the technical limitation of traditional prefabricated parts that can only provide reinforcement in a single direction. Through the reinforcement mechanism, it achieves the simultaneous reinforcement of the building structure in multiple directions. In particular, through the three-dimensional interconnected system of vertical pipes, horizontal pipes and lateral pipes, a complete spatial grid structure is formed, so that building components can be effectively reinforced with steel bars in the three main directions of vertical, horizontal and lateral directions at the same time. This all-round reinforcement system enables concrete components to overcome the traditional material limitation of "compression resistance but not tension resistance" and exhibit excellent comprehensive mechanical properties under the action of multi-directional complex loads. The structure achieves multi-directional anchoring and force transmission of pre-embedded steel bars through the combined design of pull plates and pull sleeves. The pull sleeves and pull plates on each transverse pipe form the anchor points of the steel bars, ensuring that the steel bars can fully exert their tensile strength. The precise fit between the annular disc and the annular groove ensures the stability of the pull sleeve position. This multi-point anchoring design improves the collaborative working ability between the steel bars and concrete, significantly enhancing the integrity and seismic performance of the structure, and providing prefabricated buildings with structural safety comparable to or even better than cast-in-place structures. One of the core innovations of this prefabricated building structure lies in its unique self-locking connection mechanism. The combination of the bidirectional sleeve and the self-locking block forms an actively adaptive locking system. When the bidirectional sleeves approach each other under the action of the bidirectional screw, the expansion grooves on the outer wall guide the self-locking block to expand outward, making it fit tightly against the inner wall of the transverse pipe. This "tightening with tension" self-locking feature ensures that the connection point can automatically compensate for any loosening during long-term use, maintaining long-term connection stability.

[0016] Another innovation of this prefabricated building structure lies in its integrated grouting system. Through the interconnected network formed by vertical pipes, lateral pipes and transverse pipes, it achieves all-round grouting coverage. In particular, the hexagonal groove design in the two-way spiral tube not only provides an interface for tool operation, but also forms a grouting channel to ensure that the slurry can flow smoothly to each space that needs to be filled. The design of this grouting system also takes into account the problem of air discharge. Through the exhaust function of the upper end transverse pipe, the problem of false grouting caused by bubble accumulation during the grouting process is effectively avoided. At the same time, the sealed space formed by the lateral strips and the lateral holes ensures the integrity and density of the grouting at the wall joints. This comprehensive grouting coverage forms a solid overall connection between the prefabricated walls, significantly improves the integrity and anti-seepage performance of the structure, and effectively solves the technical problems of leakage and cracking at the joints of traditional prefabricated buildings.

[0017] Compared with traditional construction methods, this structure significantly reduces the proportion of wet work on site. Most of the work can be completed in prefabrication in the factory, and the main work on site is assembly and grouting. This "dry construction" mode not only speeds up construction and shortens construction period, but also reduces construction noise and dust pollution, and improves the environmental quality of the construction site. At the same time, the standardized production of prefabricated components makes quality control more precise and stable, further improving the overall quality of the building.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 9, an assembled building structure, including a wall 11; also including a reinforcement mechanism, the reinforcement mechanism includes a plurality of vertical tubes 21 embedded in the wall 11, each vertical tube 21 is connected to a plurality of transverse tubes 22, each transverse tube 22 is respectively sleeved with a pull sleeve 23, and a pull plate 24 is respectively installed between each two pull sleeves 23, each transverse tube 22 is coaxially installed with a bidirectional sleeve 25, and each bidirectional sleeve 25 is respectively installed with an annular disk 26, and each transverse tube 22 is respectively installed with an insertion block 27, and A plurality of insert blocks 27 are respectively inserted into the annular disk 26, and an annular groove 28 is coaxially opened on the pull sleeve 23. The annular disk 26 fits in the annular groove 28. The strengthening mechanism also includes a guide bar 29 installed on the inner wall of the plurality of insert blocks, and a plurality of guide holes 210 are opened at equal intervals on the annular disk 26. The guide bar 29 is slidably connected in the guide hole 210. A plurality of expansion grooves 211 are respectively opened on the outer wall of each bidirectional sleeve 25, and a self-locking block 212 is slidably connected in each expansion groove 211. The plurality of self-locking blocks 212 are respectively slidably connected in each expansion groove 211. The two bidirectional sleeves 25 are respectively slidably connected to the limit frame 213, and a top spring 214 is installed on the side of each self-locking block 212 away from the annular disk 26, and multiple top springs 214 are respectively in contact with the limit frame 213. Further, a groove (not shown) is provided on the side of the limit frame 213 and the self-locking block 212 close to the top spring 214. The top spring 214 can be embedded in the groove for fixing to prevent the top spring 214 from running or detaching. Threaded holes 215 are respectively opened in opposite directions, and two bidirectional screw tubes 216 are respectively threadedly connected in opposite directions in the two threaded holes 215. A plurality of fixing rods 217 are installed at equal intervals between every two coaxially arranged bidirectional screw tubes 216, and a hexagonal groove 218 is respectively opened in each bidirectional screw tube 216. A plurality of steel bars are attached between every two pull plates 24, and a plurality of pull plates 24 are respectively embedded in the wall 11. The vertical tube 21, the lateral tube 32 and the transverse tube 22 are respectively connected to each other, and the transverse tube 22 is connected to the two hexagonal grooves 218.

[0022] When the walls 11 are being spliced, the guide rods 35 are first inserted into the vertical tubes 21, and then multiple walls 11 are spliced ​​together. Then, the guide rods 35 on one side are inserted into the vertical tubes 21 on the other side, and the lateral strips 33 and the lateral holes 34 between the two adjacent walls 11 are fitted together. Then, the side grooves 31 on both sides are fitted together, so that the side grooves 31 between the two walls 11 form a closed space. The pull sleeve 23 has been sleeved on the transverse tube 22, and the pull plate 24 needs to be limited. First, the limit frame 213 is placed in the transverse tube 22, and the two-way sleeves 25 are respectively inserted into the two ends of the transverse tube 22. At this time, the two limit frames 213 are respectively sleeved on the two-way sleeves 25, and then multiple insertion blocks 27 are inserted into the annular disk 26, and the guide holes 210 are connected to the guide strips 29. At this time, the limit frame 213 is pressed against the multiple top springs 214 on both sides. Due to the two-way solenoids 216 on both sides, The two screws 215 are respectively connected in opposite directions to the two threaded holes 215, so when rotating, the two bidirectional sleeves 25 can be driven to tighten, and the annular disk 26 at this time is also stuck in the annular groove 28, thereby ensuring the fixation of the pull sleeve 23, and the self-locking block 212 at this time is fitted on the inner wall of the transverse tube 22, and the pre-tightening force applied by the top spring 214 makes the self-locking block 212 always fit on the inner wall of the transverse tube 22. As the bidirectional screw tube 216 rotates, the two bidirectional sleeves 25 can be clamped, and then the self-locking block 212 is fitted on the inner wall of the transverse tube 22, so it will expand outwards under the action of the expansion groove 211 to make it more tightly fixed in the transverse tube 22, thereby not only ensuring the fixation of the annular disk 26 to the pull sleeve 23 but also ensuring the transverse strength of the transverse tube 22, and playing a reinforcing effect in the vertical direction through the steel bar, playing a reinforcing effect in the longitudinal direction through multiple pull plates 24, thus playing a tightening effect in multiple directions, thereby effectively improving the overall strength.

[0023] The fitting mechanism includes two side grooves 31 opened on both sides of the wall 11, and each vertical tube 21 is connected to and installed with a lateral tube 32. Every two lateral tubes 32 are connected to the side grooves 31 respectively. A lateral strip 33 is installed on one side of each side groove 31, and a lateral hole 34 is opened on the other side of the side groove 31. Each side groove 31 is respectively fitted with the lateral strip 33 on the adjacent wall 11, and a guide rod 35 is slidably connected in each vertical tube 21.

[0024] Since the two-way screw tube 216 is threadedly connected to the inside of the threaded hole 215, a part of the threaded hole 215 is not in threaded connection. When the wall 11 needs to be fixed by a bracket, the external screw can be threadedly connected to the threaded hole 215, thereby ensuring the convenience of connection. After the pre-fixation is completed, the bracket is removed. At this time, the fixation of all positions has been completed, and then the grouting and curing operation is carried out in the vertical tube 21. Since a guide rod 35 is installed in the vertical tube 21, and the vertical tube 21 on the other side will also be inserted into the guide rod 35 of the adjacent wall 11, the two ends of the vertical tube 21 will be sealed, and the lateral strips 33 and the lateral holes 34 are sealed with each other. A sealed gap is formed between the two side grooves 31. At this time, grouting is performed on the horizontal pipe 22 at the lower end, and the grouting pipe is threaded into the threaded hole 215, and then grouting is performed. Since a hexagonal groove 218 is provided in the two-way spiral tube 216, the slurry will flow into the vertical pipe 21 through the hexagonal groove 218, and then the slurry will flow into the sealed space of the two side grooves 31 through the lateral pipe 32 at the lower end to seal the wall 11, and then the air will be discharged through the horizontal pipe 22 at the upper end until the slurry fills the vertical pipe 21 and the side grooves 31, and the slurry overflows through the horizontal pipe 22 at the upper end, completing the overall grouting process, and then completing the assembly process.

[0025] In all the schemes mentioned above, the connection between the two parts can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be described here one by one. In the above, all fixed connections are preferably considered to be welding. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
