Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an assembled building beam-column node. Background Art

[0002] Prefabricated buildings refer to buildings that are assembled and installed on the construction site from components and accessories pre-fabricated in the factory. This type of building has the advantages of fast construction speed and low production cost.

[0003] In the actual assembly and installation process, when the beam body and the load-bearing column are connected, a node will be set to connect the two. However, some beam bodies will include two beam bodies and the two beam bodies are cross-set. One of the beam bodies serves as a fixed beam, which is usually located below the other beam body and is used to connect to the load-bearing column.

[0004] Since the fixed beam is located below another beam, its height is relatively short. Therefore, when the connecting piece is passed through the fixed beam, it is easy to damage the steel bars at the bottom of the fixed beam. The steel bars at the bottom are usually the most important. If they are damaged, the fixed beam is easily damaged, which may cause a dangerous accident.

[0049] Please refer to Figure 1-Figure 5 The present invention proposes an assembled building beam-column node 100, which is used to connect a fixed beam 210 of a beam body 200 with a load-bearing column 300. The fixed beam 210 has a plurality of steel bars 220, and the plurality of steel bars 220 are arranged at intervals along the up-down direction. The up-down direction referred to here is from the load-bearing column 300 toward the fixed beam 210 as the direction from bottom to top, and from the fixed beam 210 toward the load-bearing column 300 as the direction from top to bottom.

[0050] In the embodiment of the present invention, the assembled building beam-column node 100 includes a connecting frame 10 and a connecting member 30 .

[0051] The connecting frame 10 can be arranged in a roughly C-shaped or U-shaped shape and can be made of metal such as steel, which is not limited in this embodiment. The connecting frame 10 includes a base frame 11 and two connecting parts 12, wherein the two connecting parts 12 are connected to opposite sides of the base frame 11 to cooperate with each other to form a roughly C-shaped or U-shaped shape.

[0052] The base frame 11 is used to connect with the supporting column 300, wherein the base frame 11 and the supporting column 300 can be separate structures and fixedly connected. Of course, the base frame 11 and the supporting column 300 can also be an integrated structure, which is not limited in this embodiment.

[0053] The two connecting parts 12 cooperate with the base frame 11 to form a fixed cavity 10A, wherein the two connecting parts 12 form two opposite cavity side walls of the fixed cavity 10A, and the base frame 11 forms the cavity bottom wall of the fixed cavity 10A. The fixed cavity 10A is used to fix the fixed beam 210, for example, by connecting the two connecting parts 12 with the fixed beam 210, the fixed beam 210 is fixed in the fixed cavity 10A. The fixed cavity 10A has an opening 10B, which is open upward and for the fixed beam 210 to pass through, that is, the fixed beam 210 can enter the fixed cavity 10A through the opening 10B. Each connecting part 12 has a through hole 12A that runs through itself along its thickness direction, and the through hole 12A is connected to the fixed cavity 10A.

[0054] The connecting members 30 include at least two, and the connecting members 30 correspond to the through holes 12A passed through the connecting portion 12, and are used to pass through the fixed beam 210. It can be understood that after the connecting member 30 is passed through the through holes 12A of the connecting portion 12, the fixed beam 210 is passed through to be fixedly connected with the fixed beam 210, thereby realizing the connection between the connecting portion 12 and the fixed beam 210, and further realizing the connection between the supporting column 300 and the fixed beam 210.

[0055] Among them, the through hole 12A is arranged to extend upwardly and obliquely in the direction of the connecting part 12 where it is located toward the other connecting part 12, so that the connecting piece 30 is arranged obliquely and can at least partially pass through the gap between the two lowest steel bars 220 among the multiple steel bars 220, that is, it can partially pass through the gap between the two lowest steel bars 220 among the multiple steel bars 220, or the whole can pass through the gap between the two lowest steel bars 220 among the multiple steel bars 220.

[0056] It is understandable that if the through hole 12A is extended along the thickness direction of the connecting portion 12, and its extension direction passes through the steel bar 220 located at the bottom, then the connecting member 30 is easily damaged to the steel bar 220 at the bottom after being penetrated through the through hole 12A and the fixed beam 210, thereby affecting the stability of the prefabricated building. Based on this, the present embodiment provides an inclined through hole 12A on the connecting portion 12, so that the connecting member 30 can also be inclined after being penetrated through the through hole 12A, so that the connecting member 30 can at least partially pass through the gap between the two steel bars 220 located at the bottom. In this way, it is possible to avoid the connecting member 30 from damaging the steel bar 220, and even if the connecting member 30 contacts the steel bar 220 when penetrating the fixed beam 210, the inclined setting form will make the connecting member 30 relatively less damaging to the steel bar 220, thereby having a good protective effect on the fixed beam 210, thereby improving the safety and stability of the prefabricated building.

[0057] Please refer to Figure 3-Figure 5 In some embodiments, one of the two lowest steel bars 220 is defined as an upper steel bar 230 and the other is defined as a lower steel bar 240. It is understandable that the upper steel bar 230 and the lower steel bar 240 are arranged in an interval manner from top to bottom.

[0058] There is a gap between the connecting member 30 and the lower reinforcing bar 240 along a direction perpendicular to the direction in which the connecting member 30 is inserted. Thus, since there is a gap between the connecting member 30 and the lower reinforcing bar 240, when the connecting member 30 is inserted through the fixed beam 210, the connecting member 30 will not come into contact with the lower reinforcing bar 240, and the lower reinforcing bar 240 will not be damaged when the connecting member 30 is inserted through the fixed beam 210, so the fixed beam 210 can be well protected.

[0059] Alternatively, there is a gap between the connecting member 30 and the upper reinforcing bar 230 in a direction perpendicular to the direction in which the connecting member 30 is inserted. In this way, since there is a gap between the connecting member 30 and the upper reinforcing bar 230, when the connecting member 30 is inserted through the fixed beam 210, the connecting member 30 will not come into contact with the upper reinforcing bar 230, and there will be no situation in which the upper reinforcing bar 230 is damaged when the connecting member 30 is inserted through the fixed beam 210, so the fixed beam 210 can be well protected.

[0060] Alternatively, along a direction perpendicular to the direction in which the connector 30 is inserted, there is a gap between the connector 30 and the lower reinforcement 240, and there is a gap between the connector 30 and the upper reinforcement 230. In this way, since there is a gap between the connector 30 and the lower reinforcement 240, and there is a gap between the connector 30 and the upper reinforcement 230, when the connector 30 is inserted through the fixed beam 210, the connector 30 will not come into contact with the lower reinforcement 240 and the upper reinforcement 230, and there will be no situation in which the connector 30 will damage the lower reinforcement 240 and the upper reinforcement 230 when inserting the fixed beam 210, so the fixed beam 210 can be well protected.

[0061] Please refer to Figure 3-Figure 5 In some embodiments, along the direction perpendicular to the insertion direction of the connector 30, the size of the connector 30 is smaller than the distance between the upper steel bar 230 and the lower steel bar 240. This arrangement makes it difficult for the connector 30 to contact the upper steel bar 230 and the lower steel bar 240 when the operator operates the connector 30 to penetrate the fixed beam 210, thereby preventing the upper steel bar 230 and the lower steel bar 240 from being damaged. The operation is relatively convenient and the protection effect on the fixed beam 210 can be ensured.

[0062] Please refer to Figure 5-Figure 7 In some embodiments, the connector 30 includes an anchor bolt 31 and a connecting rod 32. The anchor bolt 31 is inserted into the through hole 12A. The connecting rod 32 is connected to the end of the anchor bolt 31 and is used to be inserted into the fixed beam 210. It is understandable that in the actual assembly process, the connecting rod 32 is first inserted into the through hole 12A and then inserted into the fixed beam 210, and then the anchor bolt 31 is inserted into the through hole 12A and fixedly connected to the connecting rod 32, such as threaded connection, so that the connecting rod 32 can be fixedly inserted into the fixed beam 210.

[0063] The connecting rods 32 of the two connecting members 30 facing each other in the direction from one connecting portion 12 to the other connecting portion 12 are mutually engaged. In this way, the mutual engagement of the connecting rods 32 of the two connecting members 30 can be utilized to increase the tensile strength of the two connecting members 30, thereby effectively preventing the connecting member 30 from being separated from the fixed beam 210 when the anchor bolt 31 is pulled out by the outside, thereby effectively improving the strength of the prefabricated building beam-column node 100 and ensuring the safety of the prefabricated building.

[0064] Please refer to Figure 5-Figure 7 In some embodiments, one of the two connecting members 30 that are mutually engaged is defined as a first connecting member 33 , and the other is defined as a second connecting member 34 .

[0065] The connecting rod 32 of the first connecting member 33 is provided with a first clamping portion 331 , and the connecting rod 32 of the second connecting member 34 is provided with a second clamping portion 341 , and the second clamping portion 341 has a clamping groove 341A. The first clamping portion 331 is inserted into the clamping groove 341A and is clamped with the second clamping portion 341 .

[0066] During the actual assembly process, the staff first makes the first clamping part 331 pass through the clamping groove 341A, and then the first clamping part 331 can be engaged with the second clamping part 341. This can prevent the two connecting rods 32 from separating, making it easy for the staff to operate. At the same time, the structure is relatively simple, the production cost is low, and it is suitable for factory production.

[0067] Please refer to Figure 6-Figure 9 In some embodiments, the first engaging portion 331 includes a substrate 3311 and a first locking tooth group 3312. The substrate 3311 is disposed in the locking slot 341A. The first locking tooth group 3312 is connected to at least one side of the substrate 3311 along its thickness direction, that is, the first locking tooth group 3312 is connected to any side of the substrate 3311 along its thickness direction, or the first locking tooth group 3312 is connected to opposite sides of the substrate 3311 along its thickness direction.

[0068] The first latching teeth group 3312 includes a plurality of first latching teeth 3312A, which are sequentially connected along the direction of penetration of the first connecting member 33. The first latching teeth 3312A are used to engage with the second engaging portion 341 to prevent the connecting rod 32 of the first connecting member 33 from being disconnected from the connecting rod 32 of the second connecting member 34.

[0069] It can be understood that the first latching tooth 3312A includes a first guiding surface 3312B and a first blocking surface 3312C (such as Fig. 9 As shown in FIG. 3 ), the first guide surface 3312B and the first blocking surface 3312C are arranged at an angle. The first guide surface 3312B is used to move the groove wall surface of the guide slot 341A so that the first clamping portion 331 can be more smoothly inserted into the slot 341A. In the process, the first clamping tooth 3312A can be elastically deformed to avoid the first clamping tooth 3312A interfering with the groove wall of the slot 341A and affecting the smoothness of the insertion of the first clamping portion 331.

[0070] The first latch tooth 3312A can undergo elastic deformation. Specifically, the first latch tooth 3312A includes a latch tooth body and an elastic member. The substrate 3311 is provided with a plurality of grooves, wherein the plurality of grooves are provided for a plurality of elastic members to be arranged one by one, wherein one end of each elastic member abuts against the bottom wall of the groove, and the other end is fixedly connected to one of the latch tooth bodies. In this way, when the latch tooth body contacts the groove wall of the groove 341A, under the action of the force exerted by the groove wall of the groove 341A, the latch tooth body will compress the elastic member and retract into the groove to avoid interference with the groove wall of the groove 341A. Then, after the latch tooth body no longer contacts the groove wall of the groove 341A, the elastic member can give a rebound force to the latch tooth body, so that the latch tooth body extends out of the groove. The present invention does not impose any specific limitation on the specific manner in which the first latch tooth 3312A can undergo elastic deformation.

[0071] The first blocking surface 3312C is used to engage with the second engaging portion 341 to block the second engaging portion 341 and prevent the first engaging portion 331 from moving in the reverse direction and escaping from the engaging slot 341A.

[0072] Of course, in other embodiments, the base plate 3311 may also be provided with a clamping rib to engage with the second clamping portion 341 to prevent the connection rod 32 of the first connecting member 33 from being disconnected from the connection rod 32 of the second connecting member 34, and this embodiment does not limit this.

[0073] Please refer to Figure 6-Figure 9 In some embodiments, the second engaging portion 341 is provided with a second engaging tooth group 3411, which is provided on the outer side of the engaging groove 341A and includes a plurality of second engaging teeth 3411A. The plurality of second engaging teeth 3411A are sequentially connected along the penetration direction of the second connecting member 34. The second engaging teeth 3411A are used to cooperate with and abut against the first engaging teeth 3312A to prevent the substrate 3311 from moving relative to the connecting rod 32 of the second connecting member 34 along the penetration direction of the second connecting member 34.

[0074] The second latching tooth 3411A includes a second guiding surface 3411B and a second blocking surface 3411C (such as Fig. 9 As shown in FIG. 1 , the second guide surface 3411B and the second blocking surface 3411C are arranged at an angle. The second guide surface 3411B is used to guide the first latching tooth 3312A to move in a direction opposite to the direction in which the second connecting member 34 is inserted. The second blocking surface 3411C is used to cooperate with and abut against the first latching tooth 3312A, that is, to block the first latching tooth 3312A, so as to prevent the substrate 3311 from moving relative to the connecting rod 32 of the second connecting member 34 along the direction in which the second connecting member 34 is inserted.

[0075] The point where the extension direction of the first connector 33 overlaps with the extension direction of the second connector 34 is defined as the intersection point, the end point of the anchor bolt 31 of the first connector 33 away from the connecting rod 32 is the first end point, and the end point of the anchor bolt 31 of the second connector 34 away from the connecting rod 32 is the second end point. It can be understood that if the sum of the distance length between the first end point and the intersection point and the distance length between the second end point and the intersection point is too large, the tensile strength of the connector 30 will be weak. Therefore, in this embodiment, the second latch 3411A cooperates with the first latch 3312A to prevent the substrate 3311 from moving along the penetration direction of the second connector 34, which can prevent the sum of the distance length between the first end point and the intersection point and the distance length between the second end point and the intersection point from being too large, thereby ensuring that the tensile strength of the connector 30 is strong, effectively improving the strength of the prefabricated building beam-column node 100, and ensuring the safety of the prefabricated building.

[0076] Please refer to Figure 6 and Figure 8 In some embodiments, at least one of the anchor bolts 31 of the first connecting member 33 and the second connecting member 34 has a rotating portion 311, that is, the first connecting member 33 has a rotating portion 311, or the second connecting member 34 has a rotating portion 311, or both the first connecting member 33 and the second connecting member 34 have a rotating portion 311, and this embodiment does not limit this.

[0077] When external force is applied to the rotating portion 311 , the rotating portion 311 can drive the connecting rod 32 to rotate around the axis of the rotating portion 311 , so that the first clamping portion 331 can pass through the clamping groove 341A and engage with the second clamping portion 341 .

[0078] For example, the staff can simultaneously rotate the rotating part 311 of the first connecting member 33 and the rotating part 311 of the second connecting member 34 so that the two rotate relative to each other, thereby allowing the first clamping part 331 to be smoothly inserted into the clamping groove 341A of the second clamping part 341, which is easy to operate and has a simple structure.

[0079] Please refer to Figure 5-Figure 6 In some embodiments, the anchor bolt 31 may be a chemical anchor bolt. Specifically, the anchor bolt 31 includes a reagent tube 312 and a bolt 313 .

[0080] The reagent tube 312 includes a tube body 3121 and an adhesive (not shown in the figure), the tube body 3121 has a receiving cavity 3121A, and the adhesive is arranged in the receiving cavity 3121A. It is understandable that the tube body 3121 can be made of glass, so the tube wall of the tube body 3121 will break when it is squeezed from the outside, so that the adhesive can flow out. The tube body 3121 can be arranged in a long strip shape, so the tube body 3121 will have two opposite ends along its length direction, wherein one end of the tube body 3121 is connected to the connecting rod 32 and has the above-mentioned rotating part 311.

[0081] The bolt 313 is connected to one end of the tube body 3121 away from the connecting rod 32. When the bolt 313 moves along the penetration direction of the connecting piece 30, the bolt 313 can squeeze the tube body 3121 to allow the adhesive to flow out and bond to the bolt 313, and be threadedly connected to the connecting rod 32, wherein the bolt 313 has an external thread, and the connecting rod 32 has an internal thread that matches the external thread.

[0082] In actual operation, the reagent tube 312 can be first connected to the connecting rod 32 and passed through the through hole 12A to the fixed beam 210, and then the bolt 313 can be passed through the through hole 12A and rotated, so that the bolt 313 can squeeze the tube wall of the tube body 3121 and cause the tube wall to be damaged. After the tube body 3121 is broken, the adhesive in the accommodating cavity 3121A will flow out, and then the bolt 313 will continue to rotate and move until it is threadedly connected to the connecting rod 32, and then wait for the adhesive to dry so that the bolt 313 is firmly set in the through hole 12A, and finally the nut and the bolt 313 can be matched and locked to realize the complete assembly process.

[0083] In this way, by bonding the bolts 313 with an adhesive, the fixing effect of the bolts 313 can be improved, so that the connecting member 30, the connecting portion 12 and the fixing beam 210 are firmly anchored together to form a reliable connection.

[0084] Of course, the present invention is not limited thereto, and in other embodiments, the anchor bolt 31 may also be an expansion anchor bolt, which may also firmly anchor the connector 30, the connecting portion 12 and the fixing beam 210 together to form a reliable connection.

[0085] Please refer to Figure 4-Figure 6 In some embodiments, the tube body 3121 further has a negative pressure chamber 3121B. It is understandable that the negative pressure chamber 3121B can be pre-evacuated so that the negative pressure chamber 3121B reaches a negative pressure environment.

[0086] The negative pressure chamber 3121B is located on the side of the accommodating chamber 3121A close to the connecting rod 32. The negative pressure chamber 3121B can generate an adsorption force on the adhesive after the bolt 313 squeezes the tube 3121. Since the through hole 12A is arranged at an angle, the adhesive will partially flow outward after flowing out. In this embodiment, the negative pressure chamber 3121B has a negative pressure adsorption force on the adhesive to effectively reduce the amount of adhesive leakage, improve the utilization rate of the adhesive, and thus improve the firmness of the connection between the connecting member 30, the connecting portion 12 and the fixed beam 210.

[0087] Specifically, due to the existence of the negative pressure chamber 3121B, after the accommodating chamber 3121A and the negative pressure chamber 3121B of the tube body 3121 are squeezed by the bolt 313, the environment near the tube body 3121 will generate negative pressure. At this time, the atmospheric pressure outside is positive pressure, so the atmospheric pressure will move toward the tube body 3121, so the atmospheric pressure can push the overflowed adhesive to move inward, that is, it can generate adsorption force on the adhesive to avoid excessive leakage of the adhesive. It should be noted that the premise for the environment near the tube body 3121 to generate a negative pressure effect is that the bolt 313 needs to squeeze the negative pressure chamber 3121B. Therefore, in the actual operation process, after the bolt 313 squeezes the accommodating chamber 3121A, it is necessary to ensure that the negative pressure chamber 3121B is squeezed, so that the environment near the tube body 3121 can generate a negative pressure effect.

[0088] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
