Description

Technical Field

[0001] The present application relates to the field of building steel bars, and in particular to a steel bar connection structure used in building construction. Background Art

[0002] Rebar is a widely used material in civil engineering. In reinforced concrete structures, the steel and concrete together bear the loads acting on the structure. For most loads, the structural members can withstand them without damage. Concrete has high compressive strength but poor tensile strength, a shortcoming that rebar can compensate for. Reinforced concrete combines the advantages of both, forming a high-strength and highly durable composite material. During the pouring process, concrete can be molded into a variety of shapes and sizes to suit different building needs. The arrangement of the rebar can be flexibly designed according to project requirements to meet specific structural requirements.

[0003] Rebar connections ensure the overall strength and stability of a structure. Rebar in buildings is often manufactured or transported in sections, so connections are needed to effectively combine different sections of steel to maintain the strength and load-bearing capacity required by the design. The quality of the joints in rebar engineering directly affects the direct load-bearing and seismic performance of structural components. Rebar connection structures are used in construction projects to ensure effective connections between rebar to meet design strength and safety requirements.

[0004] In the prior art, welding connections are usually used. Welding connections usually provide very strong connection strength and can transmit loads well. However, the above connection is a one-time forming connection. Once the connection is completed, adjustment and modification will be more difficult. Utility Model Content

[0005] In view of the deficiencies of the existing technology, the present application provides a steel bar connection structure for use in building construction.

[0006] The present application provides a steel bar connection structure for construction that adopts the following technical solution:

[0007] A steel bar connection structure for construction, comprising two arc-shaped clamping plates connected by a hinge. When the two arc-shaped clamping plates are closed, a circular socket is formed. Two steel bars are clamped between the two arc-shaped clamping plates. The ends of the arc-shaped clamping plates are fixedly connected to positioning bars. The ends of the positioning bars are provided with T-shaped slots. When the two arc-shaped clamping plates are closed, the two slots are butt-jointed and form an I-shape. Connecting blocks are provided inside the two slots, and the connecting blocks are in the shape of an I-shape.

[0008] By adopting the above technical solution, the end of the steel bar is clamped between two arc-shaped clamping plates. After the two arc-shaped clamping plates are closed, the connecting block is inserted into the corresponding card slot to prevent the two arc-shaped clamping plates from separating, realizing the fixation of the steel bar and preventing the steel bar from falling off between the two arc-shaped clamping plates. This method can flexibly adjust the position of the steel bar and improve the applicability of the product.

[0009] Preferably, through holes are formed on the surface of the connecting block, threaded holes corresponding in position are formed on the inner wall of the card slot, bolts are inserted through the through holes of the connecting block, and the threaded ends of the bolts are threadedly inserted into the threaded holes.

[0010] By adopting the above technical solution, the two arc-shaped clamping plates can be further locked, and the steel bar can be further clamped and fixed. Specifically, after the connecting block is placed in the card slot, the threaded end of the bolt is passed through the through hole, and the threaded end of the bolt is screwed into the threaded hole. At this time, under the cooperation of the connecting block and the bolt, the two arc-shaped clamping plates are stably connected together, and the two steel bars are firmly clamped and connected.

[0011] Preferably, an internally threaded sleeve is fixedly connected to one end of the steel bar close to each other. A support block is fixedly connected to the middle of the inner wall of one of the arc-shaped clamping plates. Studs are fixedly connected to both ends of the support block, and the internally threaded sleeves are all threadedly sleeved on the studs.

[0012] By adopting the above technical solution, the internally threaded sleeve at the end of the steel bar can be rotated and screwed onto the stud, thus realizing the connection purpose between the steel bar and the arc-shaped clamping plate. At this time, the steel bar will not fall off, and this method further improves the connection effect and stability.

[0013] Preferably, the studs coincide with the central axes of the steel bar, the internally threaded sleeve and the arc-shaped clamping plate.

[0014] By adopting the above technical solution, this can ensure that the internally threaded sleeve is accurately screwed onto the stud, and also further ensure that the steel bar is accurately arranged inside the arc-shaped clamping plate and is accurately aligned to prevent deviation during the installation process.

[0015] Preferably, through-going strip-shaped openings are formed on the arc-shaped clamping plates, and the strip-shaped openings are symmetrically distributed on the arc-shaped clamping plates.

[0016] By adopting the above technical solution, the strip-shaped openings are provided. When pouring cement, the cement can pass through the strip-shaped openings and enter the inside of the two arc-shaped clamping plates and contact the steel bar, thereby enhancing the connection strength and stability between the arc-shaped clamping plate and the steel bar.

[0017] Preferably, both ends of the connecting block extend to the outside of the card slot, and the side wall of the connecting block is in contact with the inner wall of the card slot.

[0018] By adopting the above technical solution, it is ensured that both ends of the connecting block have sufficient extension to ensure that they can completely extend beyond the edge of the card slot, which helps to provide sufficient grasping space when removing the connecting block and facilitates the disassembly of the connecting block. Secondly, the contact between the side wall of the connecting block and the inner wall of the card slot is a key part of the design, ensuring that the contact between the two is tight and has a certain frictional force to prevent the connecting block from falling off naturally and also avoid jamming during removal.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. First, rotate and screw the internal thread sleeve at the end of the steel bar onto the stud, so as to achieve the connection purpose between the steel bar and the arc-shaped clamping plate. At this time, the steel bar will not fall off, and this method further improves the connection effect and stability. The end of the steel bar is clamped between two arc-shaped clamping plates. Rotate the arc-shaped clamping plates. When the two arc-shaped clamping plates are closed, insert the connecting block into the corresponding card slot to prevent the two arc-shaped clamping plates from separating, realizing the fixation of the steel bar and preventing the steel bar from falling off between the two arc-shaped clamping plates. This method can flexibly adjust the position of the steel bar and improve the applicability of the product.

[0021] 2. Ensure that both ends of the connecting block have sufficient extension to ensure that they can completely extend beyond the edge of the card slot, which helps to provide sufficient grasping space when removing the connecting block and facilitates the disassembly of the connecting block. Secondly, the contact between the side wall of the connecting block and the inner wall of the card slot is a key part of the design, ensuring that the contact between the two is tight without causing excessive frictional force to avoid jamming during removal.

[0022] 3. Set strip-shaped openings. When pouring cement, the cement can pass through the strip-shaped openings and enter the inner sides of the two arc-shaped clamping plates and contact the steel bar, thereby enhancing the connection strength and stability between the arc-shaped clamping plates and the steel bar. Adopt multiple strip-shaped openings to ensure that the cement can be evenly distributed in the area between the two arc-shaped clamping plates; to ensure that the cement can fully cover the steel bar and fill the gaps.

[0028] The following is combined with Figures 1-4 This application is described in further detail.

[0029] An embodiment of the present application discloses a steel bar connection structure for construction, comprising two arc-shaped splints 1 connected by a hinge. When the two arc-shaped splints 1 are closed, a circular socket is formed. Two steel bars 5 are clamped between the two arc-shaped splints 1. Positioning bars 2 are fixedly connected to the ends of the arc-shaped splints 1. T-shaped slots 201 are provided at the ends of the positioning bars 2. When the two arc-shaped splints 1 are closed, the two slots 201 are butt-jointed and form an I-shape. Connecting blocks 3 are provided inside the two slots 201, and the connecting blocks 3 are in the shape of an I-shape.

[0030] The end of the steel bar 5 is clamped and set between the two arc-shaped clamps 1. When the two arc-shaped clamps 1 are closed, the connecting block 3 is inserted into the corresponding slot 201 to prevent the two arc-shaped clamps 1 from separating. The inner wall of the arc-shaped clamp 1 contacts the surface of the steel bar 5 to fix the steel bar 5 and prevent the steel bar 5 from falling off from between the two arc-shaped clamps 1. This method can flexibly adjust the position of the steel bar 5 and improve the applicability of the product; the I-shaped connecting block 3 is adapted to the T-shaped slot 201 to clamp and fix the two arc-shaped clamps 1 to prevent the two arc-shaped clamps 1 from detaching or loosening.

[0031] Reference Figure 3 A through hole 301 is provided on the surface of the connecting block 3, and a screw hole 202 corresponding to the position is provided on the inner wall of the slot 201. A bolt 4 is passed through the through hole 301 of the connecting block 3, and the threaded end of the bolt 4 is threadedly inserted into the screw hole 202.

[0032] The two arc-shaped splints 1 can be further locked to further clamp and fix the steel bars 5; specifically, after placing the connecting block 3 into the slot 201, the threaded end of the bolt 4 is passed through the through hole 301, and the threaded end of the bolt 4 is screwed into the screw hole 202. At this time, with the cooperation of the connecting block 3 and the bolt 4, the two arc-shaped splints 1 are stably connected together, and the two steel bars 5 are firmly clamped and connected.

[0033] Reference Figure 4 The ends of the steel bars 5 that are close to each other are fixedly connected with an internal threaded sleeve 501, and the middle part of the inner wall of one of the arc-shaped splints 1 is fixedly connected with a support block 6. Both ends of the support block 6 are fixedly connected with studs 7, and the internal threaded sleeves 501 are threadedly sleeved on the studs 7.

[0034] Before closing the two arc-shaped clamping plates 1, the internal thread sleeve 501 at the end of the steel bar 5 can be first rotated and sleeved on the stud 7, so as to achieve the connection purpose of the steel bar 5 and the arc-shaped clamping plate 1. At this time, the steel bar 5 will not fall off. This method further improves the connection effect and stability, and can realize the preliminary fixation and connection of the two steel bars 5.

[0035] The internal thread sleeve 501 provides a thread connection point and can be in threaded cooperation with the stud 7. This design allows the relationship between the steel bar 5 and other components to be adjusted or fixed by rotating the internal thread sleeve 501. The function of the support block 6 is usually to provide a support point; it is fixedly connected to the inner wall of the arc-shaped clamping plate 1, enhancing the structural stability of the arc-shaped clamping plate 1.

[0036] Refer to Figure 4 , the stud 7 is arranged coaxially with the central axes of the steel bar 5, the internal thread sleeve 501 and the arc-shaped clamping plate 1.

[0037] This can ensure that the internal thread sleeve 501 is accurately screwed onto the stud 7, and further ensure that the steel bar 5 is accurately arranged inside the arc-shaped clamping plate 1, with precise alignment, so as to prevent deviation during the installation process.

[0038] Refer to Figure 4 , strip-shaped openings 101 are provided through the arc-shaped clamping plates 1, and the strip-shaped openings 101 are symmetrically distributed on the arc-shaped clamping plates 1.

[0039] By providing the strip-shaped openings 101, when pouring cement, the cement can pass through the strip-shaped openings 101 and enter the inside of the two arc-shaped clamping plates 1 and contact the steel bar 5, thereby enhancing the connection strength and stability between the arc-shaped clamping plate 1 and the steel bar 5; using multiple strip-shaped openings 101 ensures that the cement can be evenly distributed in the area between the two arc-shaped clamping plates 1; to ensure that the cement can fully cover the steel bar 5 and fill the gaps.

[0040] Refer to Figure 1 and Figure 3 , both ends of the connecting block 3 extend outside the card slot 201, and the side wall of the connecting block 3 is in contact with the inner wall of the card slot 201.

[0041] It is necessary to ensure that both ends of the connecting block 3 have sufficient extension to ensure that they can completely extend beyond the edge of the card slot 201. This helps to provide sufficient grasping space when removing the connecting block 3, making it convenient for the hand to pick it up, so as to facilitate the disassembly of the connecting block 3; further, the surface of the connecting block 3 can be appropriately treated, such as adding texture or using anti-slip materials, so as to facilitate finger grasping and operation; secondly, the contact between the side wall of the connecting block 3 and the inner wall of the card slot 201 is a key part of the design, ensuring that the contact between the two is tight and has a certain frictional force, preventing the connecting block 3 from falling off naturally and also avoiding jamming during disassembly.

[0042] The implementation principle of a steel bar connection structure for building construction in an embodiment of the present application is as follows:

[0043] When connecting two steel bars 5, first rotate and sleeved the internal thread sleeve 501 at the end of the steel bar 5 on the stud 7, so as to achieve the connection purpose of the steel bar 5 and the arc-shaped clamping plate 1. At this time, the steel bar 5 will not fall off. This method further improves the connection effect and stability, and can thus achieve the preliminary fixation and connection of the two steel bars 5. Then rotate the arc-shaped clamping plate 1. After the two arc-shaped clamping plates 1 are closed, insert the connecting block 3 into the corresponding card slot 201 to prevent the two arc-shaped clamping plates 1 from separating, realizing the fixation of the steel bar 5 and preventing the steel bar 5 from falling off between the two arc-shaped clamping plates 1. Finally, insert the threaded end of the bolt 4 through the through hole 301 and screw the threaded end of the bolt 4 into the screw hole 202. At this time, with the cooperation of the connecting block 3 and the bolt 4, the two arc-shaped clamping plates 1 are stably connected together, and the two steel bars 5 are firmly clamped and connected. The above fixing method can also provide a stable and firm fixing effect for the two steel bars 5. The above method can flexibly adjust the position of the steel bar 5, improve the applicability of the product, and is suitable for scenarios that require rapid construction and high strength requirements.

[0044] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
