Description

Technical Field

[0001] This utility model relates to the field of building reinforcement construction technology, specifically to an anchoring node for reinforcing frame columns at intermediate floors. Background Technology

[0002] In reinforced structures, after the cross-section of the intermediate frame column is increased, the straight anchorage of the newly added longitudinal steel bars is a common anchorage method.

[0003] In the relevant existing technologies, according to current specifications and atlases, after the cross-section of the intermediate frame column is increased, the upper end of the newly added longitudinal steel bar passes through the floor slab and is connected to the upper column base by straight anchorage. The length of the straight anchorage section is not less than Lae. As shown in the atlas "Concrete Structure Strengthening Construction" 13G311-1, the anchorage node of the newly added stressed steel bar in the intermediate floor after the cross-section of the frame column is increased and strengthened is given.

[0004] However, in actual engineering, increasing the column cross-section and adding longitudinal steel bars that are directly anchored upwards will cause the frame columns in the upper part of the building to have variable cross-sections in the floors, which will affect the building's usability and spatial aesthetics. Utility Model Content

[0005] Based on the above description, this utility model provides a reinforcement anchorage node between the frame column and the intermediate floor to solve the problem that the existing intermediate floor frame column has a variable cross-section due to the addition of new steel bars that are directly anchored upwards to the upper frame column when the cross-section is increased.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] An anchoring node for reinforcing a frame column and an intermediate floor includes a floor slab, a frame column, a reinforcing frame column, and a connecting plate. The frame column is located on the upper side of the floor slab, and the reinforcing frame column is located on the lower side of the floor slab. The reinforcing frame column includes the original frame column and multiple reinforcing bars. The original frame column is coaxial with the original frame column, and the multiple reinforcing bars are distributed circumferentially along the original frame column. The floor slab has multiple through holes corresponding one-to-one with the multiple reinforcing bars, and the connecting plate is located on the upper surface of the floor slab.

[0008] The multiple reinforcing bars are inserted one-to-one into the multiple through holes and are all connected to the connecting plate.

[0009] Based on the above technical solution, the present invention can be further improved as follows:

[0010] Furthermore, the connecting plate is arranged in a ring shape and is sleeved around the periphery of the frame column.

[0011] Furthermore, the connecting plate includes at least two connecting blocks, which are joined together to form the connecting plate.

[0012] Furthermore, the cross-section of the reinforced frame column is rectangular;

[0013] The multiple reinforcing bars are divided into four corner bars and at least four side bars. The four corner bars are located at the four corners of the reinforced frame column, and one side bar is located between two adjacent corner bars.

[0014] The connecting blocks are configured in four parts, each corresponding to one of the four sides of the frame column, and each connecting block is connected to one corner reinforcement and one side reinforcement.

[0015] Furthermore, the connecting plate is provided with a plurality of connecting holes, and each of the plurality of connecting holes corresponds one-to-one with a plurality of the stressed reinforcing bars;

[0016] The anchoring nodes between the reinforced frame columns and the intermediate floors also include multiple nuts;

[0017] The upper periphery of the plurality of stressed reinforcing bars is provided with threads that are compatible with the nuts.

[0018] Furthermore, the anchoring node between the reinforced frame column and the intermediate floor also includes a frame beam, which is connected to the lower end face of the floor slab.

[0019] The multiple reinforcing bars are divided into four corner bars and at least four side bars. The four corner bars are located at the four corners of the reinforced frame column, and one side bar is located between two adjacent corner bars. The middle part of each side bar is inclined away from the frame beam.

[0020] Furthermore, the original frame column is located in the middle of the floor slab.

[0021] Furthermore, the connecting plate is square, with a side length of L, where L ≥ 150 mm, and a thickness of d, where d ≥ 5 mm.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0023] In this embodiment, multiple reinforcing bars are added to the periphery of the reinforced frame column. The upper ends of these reinforcing bars pass through multiple through holes and are all connected to the connecting plate. This anchors the reinforced frame column to the connecting plate, ensuring force transmission. There is no need for the reinforced frame column to be directly anchored upwards (Lae), preventing changes in the cross-section of the frame column and ensuring the normal use and aesthetic appeal of the building.

[0034] Please refer to Figure 1 and Figure 2 This utility model provides an anchoring node for reinforcing a frame column and an intermediate floor. It is characterized by comprising a floor slab 1, a frame column 2, a reinforced frame column 3, and a connecting plate 4. The frame column 2 is located on the upper side of the floor slab 1, and the reinforced frame column 3 is located on the lower side of the floor slab 1. The reinforced frame column 3 includes an original frame column 31 and multiple reinforcing bars 32. The original frame column 31 is coaxial with the frame column 2, and the multiple reinforcing bars 32 are distributed circumferentially along the original frame column 31. The floor slab 1 has multiple through holes 11 corresponding to the multiple reinforcing bars 32. The connecting plate 4 is located on the upper surface of the floor slab 1. The multiple reinforcing bars 32 are inserted into the multiple through holes 11 and are all connected to the connecting plate 4.

[0035] In this embodiment, the reinforced frame column 3 adds multiple reinforcing bars 32 around the periphery of the frame column 2. The upper ends of the multiple reinforcing bars 32 pass through multiple through holes 11 and are all connected to the connecting plate 4. This anchors the reinforced frame column 3 to the connecting plate 4, ensuring the transmission of force. There is no need to anchor the reinforced frame column 3 directly upwards (Lae), thus avoiding any changes in the cross-section of the frame column 2 and ensuring the normal use and aesthetic appeal of the building.

[0036] Specifically, in order to fix the plurality of the stressed reinforcing bars 32 to the connecting plate 4, in this embodiment, the following is continued... Figure 1 and Figure 2The connecting plate 4 is provided with multiple connecting holes 411, each corresponding to one of the multiple reinforcing bars 32. The anchoring node between the reinforced frame column and the intermediate floor also includes multiple nuts 5. The upper periphery of the multiple reinforcing bars 32 is provided with threads adapted to the nuts 5. Each reinforcing bar 32 corresponds to one through hole 11, one connecting hole 411, and one nut 5. The upper end of each reinforcing bar 32 passes through the corresponding through hole 11 and the connecting hole 411 in sequence, and then is screwed to the corresponding nut. The nut is pressed against the upper end face of the connecting plate 4, thereby connecting each reinforcing bar 32 to the connecting plate 4. Finally, each nut is welded to the connecting plate 4 to complete the fixed connection between the multiple reinforcing bars 32 and the connecting plate 4. In this way, the structure is safe and reliable, has good durability, and is convenient to construct.

[0037] In another embodiment, each of the connecting holes 411 may be adapted to a corresponding reinforcing bar 32. A plurality of reinforcing bars 32 are welded one-to-one into a plurality of connecting holes 411.

[0038] In this embodiment, the connecting plate 4 is arranged in a ring shape and is sleeved around the periphery of the frame column 2. Multiple connecting holes 411 are distributed at intervals along the circumference of the connecting plate 4. The gap between the lower end face of the connecting plate 4 and the upper end face of the floor slab 1 is filled with adhesive, thus bonding the connecting plate 4 to the floor slab 1. This makes the structure more stable and improves stability.

[0039] Specifically, in this embodiment, the connecting plate 4 includes at least two connecting blocks 41, which are spliced ​​together to form the connecting plate 4. The two connecting plates 4 are respectively located on both sides of the frame column 2, and are first fixedly connected to the corresponding plurality of reinforcing bars 32, and then welded together. This facilitates the layout of the connecting plates 4, allowing them to surround the perimeter of the frame column 2. It also facilitates the alignment of each connecting hole 411 with the corresponding reinforcing bar 32, avoiding situations where some connecting holes 411 are difficult to align with the corresponding reinforcing bars 32, resulting in excessive gaps between the connecting plate 4 and the floor slab 1. This simplifies operation, makes implementation easier, and saves manpower.

[0040] It should be noted that the present invention does not limit the shape of the cross-section of the original frame column 31, which can be circular, rectangular, square or irregular.

[0041] Furthermore, in this embodiment, referring to Figures 1 to 3The reinforced frame column 3 has a rectangular cross-section. Multiple reinforcing bars 32 are divided into four corner bars 321 and at least four side bars 322. The four corner bars 321 are located at the four corners of the reinforced frame column 3, and one side bar 322 is located between two adjacent corner bars 321. Four connecting blocks 41 are provided, each corresponding to one of the four sides of the frame column 2, and each connecting block 41 is connected to one corner bar 321 and one side bar 322. First, each connecting block 41 is connected to one corner bar 321 and all the side bars 322 located on one side of the connecting block 41, with each connecting block 41 tightly attached to the upper surface of the floor slab 1. Then, the four connecting blocks 41 are welded together by full penetration welding. This reduces installation difficulty and increases strength.

[0042] Specifically, this utility model does not limit the number of side reinforcement bars 322, but sets them according to the design requirements of the reinforced frame column 3. In this embodiment, there are eight side reinforcement bars 322, with two on each side of the original frame column 31. Thus, each connecting block 41 is connected to one corner reinforcement bar 321 and two side reinforcement bars 322.

[0043] In this embodiment, the anchoring node between the reinforced frame column and the intermediate floor also includes a frame beam 6, which is connected to the lower end face of the floor slab 1. The middle portion of each side reinforcement bar 322 is inclined away from the frame beam 6, thereby ensuring that each side reinforcement bar 322 avoids the frame beam 6 while being subjected to force as evenly as possible. Each side reinforcement bar 322 only needs to be connected to the connecting plate 4, without needing to pass through the frame beam 6 or be anchored within it; thus, construction is convenient.

[0044] Specifically, refer to Figure 1 and Figure 2 In this embodiment, the frame beam 6 includes a first concrete beam 61 extending along a first direction and a second concrete beam 62 extending along a second direction. Therefore, the middle portion of each side reinforcement 322 distributed on both sides of the first concrete beam 61 is inclined away from the first concrete beam 61; the middle portion of each side reinforcement 322 distributed on both sides of the second concrete beam 62 is inclined away from the second concrete beam 62, such that each side reinforcement 322 is far away from the frame beam 6.

[0045] Continue to refer to Figure 1 and Figure 2In this embodiment, the first direction and the second direction are perpendicular to each other and both are located in the horizontal plane. The reinforced frame column 3 also includes a plurality of stirrups 7; the first concrete beam 61 is provided with a first mounting through hole 11 extending along the second direction, and the second concrete beam 62 is provided with a second mounting through hole 11 extending along the first direction. The first mounting through hole 11 and the second mounting through hole 11 are for the stirrups 7 to pass through.

[0046] In this embodiment, the original frame column 31 is located in the middle of the floor slab 1, and the original frame is surrounded by the floor slab 1.

[0047] In this embodiment, the connecting plate 4 is square, with a side length of L ≥ 150 mm and a thickness of d ≥ 5 mm. The design tensile strength of the connecting plate 4 is not less than the design tensile bearing capacity of the plurality of reinforcing bars 32.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
