Description

Technical Field

[0001] The invention belongs to the technical field of building structural components, and in particular relates to a building structural component and an installation method thereof. Background Art

[0002] Prefabricated building parts, or prefabricated components, refer to building components that are prefabricated before construction according to specified specifications and precision, based on design drawings or samples. They mainly include:

[0003] Precast concrete frame beam: a column used to support the building structure.

[0004] Precast concrete composite beam: A beam made of precast concrete components and cast-in-place concrete layers.

[0005] Precast concrete shear wall interior and exterior panels: used to enhance the shear resistance of the building structure and as a component of the interior and exterior walls of the building.

[0006] Precast concrete reinforced truss composite floor: a floor made up of reinforced trusses and precast concrete slabs.

[0007] Precast concrete composite floor with ribbed base: Precast concrete composite floor with ribbed base enhances the bearing capacity and stability of the floor.

[0008] Precast concrete stair slabs, balcony slabs, and air-conditioning slabs: precast components used for building stairs, balconies, and air-conditioning outdoor unit platforms respectively.

[0009] Precast concrete parapet: a low wall used at the edge of a building roof for protection.

[0010] Precast concrete exterior wall panels: used for decoration and protection of building exterior walls, with a variety of colors and textures.

[0011] Among them, when the precast concrete frame beams are relatively connected, a full grouting sleeve is required. The traditional full grouting sleeve is generally composed of a cylindrical sleeve and grouting holes and grouting holes integrally formed at both ends. Although this full grouting sleeve is more commonly used at this stage, it still has some defects:

[0012] 1. The full grouting sleeve can only connect the reserved steel bars of the prefabricated beam horizontally, and cannot be reinforced and connected in the longitudinal direction, which leads to low overall connection strength. In addition, the steel bars are directly inserted into the full grouting sleeve for grouting. The steel bars and the full grouting sleeve are not effectively connected, but only fastened together by the adhesion of the slurry after solidification, and the connection is prone to faults.

[0013] 2. During the grouting process, due to the small internal volume of the full grouting sleeve, it is impossible to vibrate it after grouting, so that the residual air inside it cannot be discharged, resulting in a certain cavity after the slurry solidifies, affecting the connection strength, reducing the structural stability between the prefabricated beams, and failing to achieve the expected construction quality;

[0014] 3. The grouting method of the full grouting sleeve is single, and the grouting holes can only be used to grout the full grouting sleeve one by one, and integrated grouting cannot be achieved, which makes the grouting efficiency low and is not conducive to efficient construction. Summary of the invention

[0015] The purpose of the present invention is to provide a building structural component and an installation method thereof, which can strengthen the connection between the sleeve and the steel bar and realize reinforcement in the longitudinal direction to form an annular reinforcement frame, while reducing the generation of cavities and improving the connection strength between prefabricated beams. At the same time, it has a variety of grouting methods to improve the grouting efficiency, thereby improving the construction efficiency.

[0016] The technical solution adopted by the present invention is as follows:

[0018] Wherein, the transverse connecting portion comprises:

[0019] Center sleeve;

[0020] The fastening sleeves are symmetrically mounted at both ends of the central sleeve, and the two fastening sleeves can rotate relative to each other to change the relative position and oscillate the concrete. The fastening sleeves are integrally formed with a first tubular opening at one end away from the central sleeve, and the inner wall of the first tubular opening is provided with a first internal thread;

[0021] A fastener is arranged at one end of the fastening sleeve near the first tubular opening, the fastener is trumpet-shaped, and a shrinkage gap for shrinkage is provided in a circumferential array, and a clamping protrusion is integrally formed on the inner wall of one end of the fastener at a small diameter so as to clamp the steel bar when the steel bar is inserted therein;

[0022] Wherein, the longitudinal connecting portion comprises:

[0023] A longitudinal sleeve, arranged between the longitudinally adjacent fastening sleeves, wherein an inner through groove is provided inside the longitudinal sleeve;

[0024] The longitudinal bolts are symmetrically slidably installed at the two ends of the longitudinal sleeves, and are threadedly connected to the first tubular opening through the first internal thread, so as to position and connect the longitudinally adjacent fastening sleeves.

[0025] As a preferred solution, a threaded hole is formed through the center sleeve, and a positioning bolt for positioning the steel bar or the fastening sleeve is threadedly connected thereto.

[0026] As a preferred embodiment, one of the fastening sleeves is fixedly connected to the center sleeve, and the other opposite fastening sleeve is rotatably connected to the center sleeve. The two fastening sleeves are in contact with each other, and a semicircular threaded hole compatible with the positioning bolt is provided in a circular array at one end of the contacting sleeves.

[0027] As a preferred solution, the large diameter end of the fastener is fixedly embedded in the inner wall of the steel bar insertion end of the fastening sleeve, and the fastener is made of a hard elastic material.

[0028] As a preferred solution, external threads are symmetrically provided at both ends of the center sleeve, and a second internal thread threadedly connected to the external thread is provided on the inner wall of the fastening sleeve near one end of the center sleeve, so that the two fastening sleeves are threadedly connected to the two ends of the center sleeve.

[0029] As a preferred solution, the large diameter end of the fastener is slidably embedded in the inner wall of the steel bar insertion end of the fastening sleeve, and a limiting rope is fixed around the outer periphery of the fastener for hooping the end of the steel bar to push the fastener to move.

[0030] As a preferred solution, the center sleeve is integrally formed with limiting convex rings around the inner walls at both ends close to the fastener, so as to limit and shrink the fastener when it slides and pushes toward the inside.

[0031] As a preferred solution, a through hole is formed in the longitudinal bolt so as to be connected with the fastening sleeve for the circulation of grouting liquid when connected with the first tubular opening.

[0032] As a preferred solution, a special-shaped nut is integrally formed at the end of the longitudinal bolt, and the special-shaped nut is slidably embedded in the inner through groove and fits with the inner wall of the inner through groove.

[0033] A method for installing a building structure component, applied to the above-mentioned building structure component, comprises the following steps:

[0034] Step 1: Installation of the transverse connection part: rotate the two sets of fastening sleeves relative to each other until the first tubular opening is vertically upward, then insert the steel bars reserved at the left end and the right end of the prefabricated beam into the interior through the insertion port of the fastening sleeve, and gradually insert the large diameter end of the fastener into the small diameter end, and expand the fastening petals formed by the division on it outward, and at the same time, the clamping protrusions are attached to the surface of the steel bar, and are continuously engaged and separated from the texture on the surface until the steel bar is inserted into the specified depth;

[0035] Step 2, exhaust construction: after all the steel bars are butt-jointed through the transverse connection part, a pre-prepared sealing ring is embedded in the steel bar insertion end of the fastening sleeve or a sealing ring is formed by plugging with quick-drying mud, and then the gel liquid is injected through the grouting hole, and the slurry outlet hole is vented to exhaust the air in the fastening sleeve until the gel liquid is sprayed out from the other first tubular opening, and then the injection of the gel liquid is stopped;

[0036] Step 3: Grouting construction: After all the gas inside the transverse connection parts is evacuated by step 2, the slurry is injected from the grouting holes, and the gel liquid is discharged from the slurry outlet holes until the gel liquid is completely discharged from the slurry outlet holes. At the same time, the slurry evenly overflows from the slurry outlet holes, and then the slurry injection is stopped;

[0037] Step 4: Shake the slurry evenly: connect the longitudinal connection part through the first internal thread on one of the first tubular openings, and alternately connect the longitudinal connection parts between the two ends of the longitudinally adjacent transverse connection parts, then relatively rotate the two sets of fastening sleeves to shake the slurry evenly, and then check the slurry in the first tubular opening. If the grouting is not dense, it needs to be supplemented;

[0038] Step 5, installation of the longitudinal connection part: After the grouting of all the transverse connection parts is completed, the fastening sleeve is relatively rotated to a state opposite to the first tubular opening between the longitudinally adjacent fastening sleeves, and the other remaining longitudinal bolt of the longitudinal connection part in step 4 is used to thread the longitudinally adjacent first tubular openings, so that the longitudinal connection part and the transverse connection part form a ring-shaped structural frame that is circularly connected end to end, and each first tubular opening is blocked to avoid leakage, thereby completing the connection between the two ends of the prefabricated beam.

[0039] The technical effects achieved by the present invention are:

[0040] The present invention cooperates with the fastening sleeve by arranging a fastening sleeve. During the process of inserting the steel bar into the fastening sleeve, the fastening petal can expand outward, and at the same time, the clamping protrusion fits on the surface of the steel bar, and continuously engages and separates with the texture on the surface, so as to limit and clamp the steel bar. Due to the existence of the texture on the surface of the steel bar, after the steel bar is inserted into the fastener, due to its trumpet-shaped structure and the engagement of the clamping protrusion with the steel bar texture, it can only be inserted but not withdrawn in the reverse direction, thereby improving the connection strength between the steel bar and the structural component, so that the connection between the steel bar and the structural component is not only connected by the adhesion of the solidified slurry, thereby ensuring the horizontal connection quality between the prefabricated beams.

[0041] The present invention arranges a longitudinal sleeve, a longitudinal bolt and a fastening sleeve in coordination. After grouting, the longitudinally adjacent fastening sleeves can be connected end to end through the longitudinal sleeve and the longitudinal bolt to form an annular structural frame that is circularly connected end to end, thereby achieving reinforcement of the longitudinal connection of the precast beam. The coordination of the transverse component and the longitudinal component can be utilized to improve the overall connection strength of the precast beam at the connection position, thereby making it more resistant to compression and load-bearing, reducing the probability of a fault at the connection, and further improving the construction quality.

[0042] The present invention provides a central sleeve to cooperate with the fastening sleeve, so that the two sets of fastening sleeves can rotate relative to each other as needed to shake the slurry injected therein, and at the same time, the construction method of injecting the gel liquid before grouting and then injecting the slurry can greatly reduce the probability of generating cavities after the slurry solidifies, thereby ensuring the connection strength after the slurry solidifies, so that the structural stability between the prefabricated beams is increased, and the expected construction quality can be achieved;

[0043] The present invention arranges a longitudinal sleeve, a longitudinal bolt and a fastening sleeve in cooperation, and a special-shaped nut is opened in the longitudinal bolt. The longitudinally adjacent fastening sleeves are connected end to end by using the longitudinal sleeve and the longitudinal bolt to form an annular structural frame that is circularly connected end to end. The cavities inside the frame can be connected at the same time, and then all the fastening sleeves can be connected into a communicating pipeline. Then, only one grouting hole and a grouting outlet hole need to be retained to synchronously grout all the structural components, and there is no need to grout each structural component separately, thereby improving the grouting efficiency and changing the grouting method. During construction, it can be selected according to needs, which is conducive to efficient construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. Embodiment 1:

[0073] like Figure 1-Figure 7 As shown, a building structure component includes a transverse connecting part connecting the transverse reinforcement of the precast beam and a longitudinal connecting part connecting the longitudinally adjacent transverse connecting parts, so that the reserved reinforcement at the left end and the reserved reinforcement at the right end of the precast beam are connected and fixed to each other.

[0074] Refer to the attached Figure 3-Figure 5 The transverse connection part includes a central sleeve 1, fastening sleeves 2 symmetrically installed at both ends of the central sleeve 1, and a fastener 3 fixedly installed in the fastening sleeve 2. The fastener 3 can be used to limit and clamp the steel bars inserted therein to ensure that the steel bars are effectively connected to the fastening sleeve 2.

[0075] Refer to the attached Figure 3-Figure 5 , one of the fastening sleeves 2 is fixedly connected to the center sleeve 1, and the other opposite fastening sleeve 2 is rotatably connected to the center sleeve 1, and the opposite ends of the two are in conflict with each other. At the same time, an annular groove is provided on the outer surface of the center sleeve 1, and an annular tooth is integrally formed on the inner wall of the opposite end of the fastening sleeve 2. By embedding the annular tooth into the annular groove, the fastening sleeve 2 and the center sleeve 1 will not separate during rotation, ensuring the connection stability (such as the attached Figure 5 As shown); wherein, the two fastening sleeves 2 are capable of relative rotation. During grouting, the slurry can be shaken evenly by relatively rotating the fastening sleeves 2 to reduce the generation of cavities.

[0076] Specifically, a first tubular opening 21 is integrally formed at one end of the fastening sleeve 2 away from the center sleeve 1. One of the first tubular openings 21 on the two oppositely arranged fastening sleeves 2 can serve as a grouting hole, and the other can serve as a slurry outlet hole, so as to perform grouting inside.

[0077] Refer to the attached Figure 4-Figure 5, wherein a threaded hole 11 is penetrated through the center sleeve 1 and is threadedly connected with a positioning bolt 5. In contrast, a semicircular threaded hole 23 adapted to the positioning bolt 5 is opened in a circumferential array at one end of the two fastening sleeves 2 that are in conflict with each other. The two semicircular threaded holes 23 can be combined into a complete threaded through hole for connecting the positioning bolt 5. Then, when the two fastening sleeves 2 rotate relative to each other, the positioning bolt 5 is inserted into the threaded through hole composed of the two semicircular threaded holes 23 and the threaded hole 11 for positioning, and the positioning bolt 5 is used to fix the steel bar in place when the steel bar is fully inserted into the center sleeve 1.

[0078] In this embodiment, four semicircular threaded holes 23 are arranged in a circumferential array at the end of the fastening sleeve 2, so that the fastening sleeve 2 can be positioned for a relative ninety-degree rotation to ensure its accurate rotation angle and facilitate relative connection with the longitudinally adjacent fastening sleeve 2.

[0079] Refer to the attached Figure 5 The fastener 3 is trumpet-shaped, and its large-diameter end is fixedly embedded in the inner wall of one end of the fastening sleeve 2 close to the first tubular opening 21, and a shrinkage gap 31 for its shrinkage is provided in a circumferential array on its surface, thereby separating and forming a plurality of fixed petals. At the same time, the fastener 3 is integrally formed with a snap-in protrusion 32 on the inner wall of its small-diameter end, which is convenient for snapping with the texture on the surface of the steel bar. During the process of inserting the steel bar into the fastening sleeve 2, it can expand outward through the fastening petal, and at the same time, the snap-in protrusion 32 is attached to the surface of the steel bar, and is continuously snapped and separated with the texture on its surface, so as to limit and clamp the steel bar. Due to the existence of the texture on the surface of the steel bar, after the steel bar is inserted into the fastener 3, due to its trumpet-shaped structure and the snap-in protrusion 32 snapping with the texture of the steel bar, it can only be inserted and cannot be reversed and withdrawn, thereby improving the connection strength between the steel bar and the structural component.

[0080] In this embodiment, the fastener 3 is made of spring steel so that it can elastically deform when clamping the steel bar to achieve the purpose of clamping the steel bar; of course, in other embodiments, the fastener 3 can be made of other hard elastic materials, such as stainless steel, copper alloy, titanium alloy, nickel alloy, etc.

[0081] Refer to the attached Figure 6-Figure 7 The longitudinal connection part includes a longitudinal sleeve 6 and longitudinal bolts 7 symmetrically slidably installed at both ends of the longitudinal sleeve 6. At the same time, the inner wall of the first tubular opening 21 is provided with a first internal thread 22 adapted to the longitudinal bolt 7, and then the longitudinal bolt 7 is connected to the fastening sleeve 2 through the first internal thread 22, thereby connecting the longitudinally adjacent fastening sleeves 2 to form a longitudinal support reinforcement, thereby improving the structural strength of the prefabricated beam connection surface.

[0082] Specifically, an inner through groove 61 is opened inside the longitudinal sleeve 6, and at the same time, a special-shaped nut 71 is integrally formed at the end of the longitudinal bolt 7, and fits with the inner wall of the inner through groove 61, so that the longitudinal bolt 7 can be driven to rotate synchronously when the longitudinal sleeve 6 is rotated; in the present embodiment, a structure with a regular hexagonal cross-section is set, and the regular hexagonal special-shaped nut 71 is slidably embedded in the regular hexagonal inner through groove 61, so that the longitudinal bolt 7 can be telescopically slid relative to the longitudinal sleeve 6, and at the same time, a universal wrench can be used to rotate the longitudinal bolt 7 synchronously while rotating the longitudinal sleeve 6, so as to screw it into the first tubular opening 21 for easy installation, thereby forming a ring-shaped structural frame connected end to end in a loop, thereby realizing the reinforcement of the longitudinal connection of the prefabricated beam, thereby utilizing the cooperation of the transverse component and the longitudinal component to improve the overall connection strength of the prefabricated beam at the connection position, making the compression resistance and load-bearing capacity stronger, reducing the probability of fault phenomenon at the connection, and further improving the construction quality.

[0083] like Figure 1-Figure 7 As shown, the method for installing building structure components in this embodiment includes the following steps:

[0084] Step 1, installation of the transverse connection part: rotate the two sets of fastening sleeves 2 relative to each other until the first tubular opening 21 is vertically upward, then insert the steel bars reserved at the left end and the right end of the prefabricated beam into the interior through the insertion port of the fastening sleeve 2, and at the same time gradually insert the large diameter end of the fastener 3 into the small diameter end, and expand the fastening petals formed by the division on it outward, and at the same time, the snap-fitting protrusion 32 is attached to the surface of the steel bar, and is continuously engaged and separated from the texture on its surface until the steel bar is inserted into the specified depth.

[0085] Step 2, exhaust construction: After all the steel bars are butt-jointed through the transverse connection part, a pre-prepared sealing ring 4 is embedded in the steel bar insertion end of the fastening sleeve 2 or the sealing ring 4 is formed by sealing with quick-drying mud, and then the gel liquid is injected through the grouting hole, and the slurry outlet hole is vented to discharge the air in the fastening sleeve 2 until the other first tubular opening 21 sprays out the gel liquid, and then the injection of the gel liquid is stopped.

[0086] Step 3: Grouting construction: After exhausting the gas inside all the transverse connections in step 2, inject slurry from the grouting holes and discharge the gel liquid from the slurry outlet holes until the gel liquid is completely discharged from the slurry outlet holes. At the same time, stop injecting slurry when slurry overflows evenly from the slurry outlet holes.

[0087] The construction method of injecting gel liquid before grouting and then injecting slurry to discharge the gel liquid can greatly reduce the probability of cavity formation after the slurry solidifies, thereby ensuring the connection strength after the slurry solidifies, increasing the structural stability between prefabricated beams, and achieving the expected construction quality.

[0088] Step 4: Shake the slurry evenly: On one of the first tubular openings 21, the longitudinal connection part is threadedly connected by the first internal thread 22, and the longitudinally adjacent transverse connection parts are alternately connected to the longitudinal connection parts between their two ends, and then the two sets of fastening sleeves 2 are relatively rotated to shake the slurry evenly, and then the slurry in the first tubular opening 21 is checked. If the grouting is not dense, it needs to be supplemented.

[0089] Step 5, installation of the longitudinal connection part: After the grouting of all the transverse connection parts is completed, the fastening sleeve 2 is relatively rotated to a state opposite to the first tubular opening 21 between the longitudinally adjacent fastening sleeves 2, and the other remaining longitudinal bolt 7 of the longitudinal connection part in step 4 is used to thread the longitudinally adjacent first tubular openings 21, so that the longitudinal connection part and the transverse connection part form a ring-shaped structural frame that is circularly connected end to end, and each first tubular opening 21 is blocked to avoid leakage, thereby completing the connection between the two ends of the prefabricated beam. Embodiment 2:

[0090] like Figure 1-Figure 9 As shown, a building structure component, this embodiment is basically the same as the first embodiment, the difference is only in that:

[0091] Refer to the attached Figure 8-Figure 9 A through hole 72 is formed in the longitudinal bolt 7. When the longitudinal sleeve 6 and the longitudinal bolt 7 are used to connect the longitudinally adjacent fastening sleeves 2 end to end through the first tubular opening 21, a ring-shaped structural frame connected end to end can be formed, and the internal cavities can be connected at the same time, so that all the fastening sleeves 2 can be connected into a connected pipeline (such as the attached Fig. 9 When grouting, only one grouting hole and one grouting outlet hole are needed to carry out synchronous grouting on all structural components, and there is no need to grout each structural component separately (as shown in the attached figure). Figure 1 as shown).

[0092] like Figure 1-Figure 9 As shown, the method for installing building structure components in this embodiment includes the following steps:

[0093] Step 1, installation of the transverse connection part: insert the steel bars reserved at the left end and the right end of the prefabricated beam into the interior through the plug-in interface of the fastening sleeve 2, and gradually insert the large-diameter end of the fastener 3 into its small-diameter end, and expand the fastening petals formed by the division on it outward, and at the same time, the snap-fitting protrusion 32 is attached to the surface of the steel bar, and is continuously engaged and separated from the texture on its surface until the steel bar is inserted into the specified depth.

[0094] Step 2, installation of the longitudinal connection part: rotate the fastening sleeve 2 relatively to a state opposite to the first tubular opening 21 between the longitudinally adjacent fastening sleeves 2, and use the longitudinal bolt 7 to threadably connect the longitudinally adjacent first tubular openings 21, so that the longitudinal connection part and the transverse connection part form an annular structural frame that is circularly connected end to end, and retain two first tubular openings 21 at the head and tail to serve as grouting holes and slurry outlet holes.

[0095] Step 3, exhaust construction: the steel bar insertion end of the fastening sleeve 2 is sealed with quick-drying mud to form a sealing ring 4, and then the gel liquid is injected through the grouting hole, and the slurry outlet hole is vented to exhaust the air in the fastening sleeve 2 until the other first tubular opening 21 sprays out the gel liquid, and then the injection of the gel liquid is stopped;

[0096] Step 4, grouting construction: After all the gas inside the transverse connection parts is evacuated by step 2, the slurry is injected from the grouting holes, and the gel liquid is discharged from the slurry outlet holes until the gel liquid is completely discharged from the slurry outlet holes. At the same time, the slurry evenly overflows from the slurry outlet holes, then stop injecting the slurry, and use the longitudinal bolts 7 to connect the two retained first tubular openings 21 to avoid leakage, and then wait for the slurry to solidify. Embodiment three:

[0097] like Figure 10-15 As shown, a building structure component includes a transverse connecting part connecting the transverse reinforcement of the precast beam and a longitudinal connecting part connecting the longitudinally adjacent transverse connecting parts, so that the reserved reinforcement at the left end and the reserved reinforcement at the right end of the precast beam are connected and fixed to each other.

[0098] Among them, the transverse connecting part includes a central sleeve 1, fastening sleeves 2 symmetrically installed at both ends of the central sleeve 1, and a fastener 3 fixedly installed in the fastening sleeve 2. The fastener 3 can be used to limit and clamp the steel bars inserted therein to ensure that the steel bars are effectively connected to the fastening sleeve 2.

[0099] Refer to the attached Figure 11-13 External threads 12 are symmetrically provided at both ends of the center sleeve 1, and a second internal thread 24 threadedly connected to the external thread 12 is provided on the inner wall of the fastening sleeve 2 close to one end of the center sleeve 1, so that the two fastening sleeves 2 are threadedly connected to the two ends of the center sleeve 1; at the same time, the two fastening sleeves 2 can rotate relative to each other. During grouting, the slurry can be shaken evenly by relatively rotating the fastening sleeves 2 to reduce the generation of cavities.

[0100] Specifically, a first tubular opening 21 is integrally formed at one end of the fastening sleeve 2 away from the center sleeve 1, and one of the first tubular openings 21 on the two oppositely arranged fastening sleeves 2 can serve as a grouting hole and the other can serve as a slurry outlet hole, so as to grout the interior thereof, and a hexagonal nut 25 is integrally formed at the end close to the first tubular opening 21, so as to use a universal wrench to relatively rotate the fastening sleeve 2 and the center sleeve 1.

[0101] Of course, in other embodiments, the hexagonal nut 25 may not be provided, and the selection is made according to actual production requirements.

[0102] Refer to the attached Figure 11-Figure 12 A threaded hole 11 is formed through the center sleeve 1 and is threadedly connected with a positioning bolt 5. When the steel bar is fully inserted into the center sleeve 1, the positioning bolt 5 is used to fix the steel bar in place.

[0103] Refer to the attached Figure 10-13 The fastener 3 is trumpet-shaped, and its large-diameter end is slidably embedded in the inner wall of the fastening sleeve 2 near the first tubular opening 21, and a shrinkage gap 31 for its shrinkage is provided in a circumferential array on its surface, thereby separating and forming a plurality of fixed petals. At the same time, the fastener 3 is integrally formed with a snap-fitting protrusion 32 on the inner wall of its small-diameter end, which is convenient for snapping with the texture on the surface of the steel bar.

[0104] Furthermore, in this embodiment, a limiting rope 33 is fixed around the outer periphery of the fastener 3 for hooping the end of the steel bar to push the fastener 3 to move. In contrast, the inner walls of the two ends of the center sleeve 1 close to the fastener 3 are integrally formed with limiting convex rings 13. During the process of inserting the steel bar into the fastening sleeve 2, the end of the steel bar is pressed against the limiting rope 33, thereby pushing the entire fastener 3 to move into the center sleeve 1, and at the same time, the limiting convex ring 13 is used to limit and shrink it, and then the fastening petal is continuously contracted, and the clamping protrusion 32 is attached to the surface of the steel bar, so that the steel bar is limited and clamped (as shown in the attached figure). Fig.13 As shown in the figure, due to the presence of the surface texture of the steel bar, after the steel bar is inserted into the fastener 3, due to its trumpet-shaped structure and the engagement of the clamping protrusion 32 with the steel bar texture, it can only be inserted and cannot be withdrawn in the reverse direction. After it is fully inserted, the fastening sleeve 2 is rotated relative to the center sleeve 1, and the threaded connection is used to shrink it toward the center of the center sleeve 1, thereby tightly positioning the fastener 3 so that it cannot rebound, thereby ensuring the stability of the clamping of the steel bar.

[0105] In this embodiment, the fastener 3 is also made of spring steel so that it can be elastically deformed when clamping the steel bar, thereby achieving the purpose of clamping the steel bar.

[0106] Refer to the attached Figure 14-15The longitudinal connection part includes a longitudinal sleeve 6 and longitudinal bolts 7 symmetrically slidably installed at both ends of the longitudinal sleeve 6. At the same time, the inner wall of the first tubular opening 21 is provided with a first internal thread 22 adapted to the longitudinal bolt 7, and then the longitudinal bolt 7 is connected to the fastening sleeve 2 through the first internal thread 22, thereby connecting the longitudinally adjacent fastening sleeves 2 to form a longitudinal support reinforcement, thereby improving the structural strength of the prefabricated beam connection surface.

[0107] Specifically, an inner through groove 61 is opened inside the longitudinal sleeve 6, and at the same time, a special-shaped nut 71 is integrally formed at the end of the longitudinal bolt 7, and fits with the inner wall of the inner through groove 61, so that the longitudinal bolt 7 can be driven to rotate synchronously when the longitudinal sleeve 6 is rotated; in the present embodiment, a structure with a regular octagonal cross-section is set, and the regular octagonal special-shaped nut 71 is slidably embedded in the regular octagonal inner through groove 61, so that the longitudinal bolt 7 can be telescopically slid relative to the longitudinal sleeve 6, and at the same time, a universal wrench can be used to rotate the longitudinal bolt 7 synchronously while rotating the longitudinal sleeve 6, so as to screw it into the first tubular opening 21 for easy installation, thereby forming a ring-shaped structural frame connected end to end in a loop, thereby realizing the reinforcement of the longitudinal connection of the prefabricated beam, thereby utilizing the cooperation of the transverse component and the longitudinal component to improve the overall connection strength of the prefabricated beam at the connection position, making the compression resistance and load-bearing capacity stronger, reducing the probability of fault phenomenon at the connection, and further improving the construction quality.

[0108] like Figure 10-15 As shown, the method for installing building structure components in this embodiment includes the following steps:

[0109] Step 1, installation of the transverse connection part: insert the steel bars reserved at the left end and the right end of the precast beam into the interior through the plug interface of the fastening sleeve 2, and at the same time gradually insert the large diameter end of the fastener 3 into the small diameter end, and expand the fastening petals formed on it outward, and then push the end of the steel bar against the limiting rope 33, thereby pushing the entire fastener 3 to move into the center sleeve 1, and at the same time use the limiting convex ring 13 to limit and shrink it, and then continuously shrink the fastening petals, and at the same time, the clamping protrusion 32 fits on the surface of the steel bar until the steel bar is inserted into the specified depth, rotate the fastening sleeve 2 relative to the center sleeve 1, and use the threaded connection to shrink it toward the center of the center sleeve 1, and then press the fastener 3 to position it so that it cannot rebound, and rotate the two sets of fastening sleeves 2 relative to each other until the first tubular opening 21 is vertically upward.

[0110] Step 2, exhaust construction: After all the steel bars are butt-jointed through the transverse connection part, a pre-prepared sealing ring 4 is embedded in the steel bar insertion end of the fastening sleeve 2, and then the gel liquid is injected through the grouting hole, and the slurry outlet hole is vented to discharge the air in the fastening sleeve 2 until the other first tubular opening 21 sprays out the gel liquid, and then the injection of the gel liquid is stopped.

[0111] Step 3: Grouting construction: After exhausting the gas inside all the transverse connections in step 2, inject slurry from the grouting holes and discharge the gel liquid from the slurry outlet holes until the gel liquid is completely discharged from the slurry outlet holes. At the same time, stop injecting slurry when slurry overflows evenly from the slurry outlet holes.

[0112] Step 4: Shake the slurry evenly: On one of the first tubular openings 21, the longitudinal connection part is threadedly connected by the first internal thread 22, and the longitudinally adjacent transverse connection parts are alternately connected to the longitudinal connection parts between their two ends, and then the two sets of fastening sleeves 2 are relatively rotated to shake the slurry evenly, and then the slurry in the first tubular opening 21 is checked. If the grouting is not dense, it needs to be supplemented.

[0113] Step 5, installation of the longitudinal connection part: After the grouting of all the transverse connection parts is completed, the fastening sleeve 2 is relatively rotated to a state opposite to the first tubular opening 21 between the longitudinally adjacent fastening sleeves 2, and the other remaining longitudinal bolt 7 of the longitudinal connection part in step 4 is used to thread the longitudinally adjacent first tubular openings 21, so that the longitudinal connection part and the transverse connection part form a ring-shaped structural frame that is circularly connected end to end, and each first tubular opening 21 is blocked to avoid leakage, thereby completing the connection between the two ends of the prefabricated beam.

[0114] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
