Description

TECHNICAL FIELD

[0002] The plant bar, also known as the seed bar, is a kind of steel bar post anchoring technology in the building structure seismic reinforcement engineering. It uses the locking force of the structural glue to tightly bond the steel bar and the base material such as concrete together. This technology is mainly used for the connection and anchoring of concrete structures and is the best choice for the application of structure plant bar reinforcement and heavy load fastening. In building reconstruction, the plant bar technology is mainly used in the following three aspects:

[0003] Firstly, reinforcement and reinforcement, for the parts with insufficient strength or the parts needing to increase the bearing capacity of the original structure, the number of steel bars can be increased through the plant bar technology, so as to improve the overall bearing capacity of the structure.

[0004] Secondly, connection and anchoring, the plant bar technology can be used to connect the new and old structures or anchor the components on the base material, so as to ensure the stability and safety of the structure.

[0005] Thirdly, remedying construction defects, if the steel bars are missing or deviate from the designed position during construction, the plant bar technology can be used to remedy the defects, so as to avoid affecting the overall structure.

Moreover, in the building renovation process, the use of blocks optimizes the structural performance and seismic resistance. The hollow reinforcement design mode is used in the reinforced masonry building mode, which can meet the requirements of the actual structure for pouring concrete and forming beams, columns and other structures inside the wall. Although it belongs to the wall bearing mode, it increases the composition of the column grid in function, which has a very large seismic effect on earthquakes. Magnetic tile, block masonry has good fire resistance and durability, and is suitable for various climate conditions, especially in cold areas, frozen method can be used for masonry in winter, without special insulation measures.

[0037] The other advantages and effects of the present application can be easily understood by the person skilled in the art from the content disclosed in the present specification. The present application can also be implemented or applied by other different specific embodiments, and each detail in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application.

[0038] Specific embodiment one: combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , figure, Figure 10 , Figure 11 and Figure 12In the present embodiment, the self-docking reinforced block structure comprises a hollow block body 1 and a docking steel bar assembly 11. The hollow block body 1 can be a hollow block product in the prior art, which can have the same structure as the hollow block in the prior art. The docking steel bar assembly 11 is arranged in the hollow block body 1. The docking steel bar assembly 11 comprises an external embedded steel bar 11-1, a lap joint 11-2 and an internal steel bar 11-3. The external embedded steel bar 11-1 is a post-embedded steel bar matched with the original structure 20. One end of the external embedded steel bar 11-1 is arranged on the original structure 20. The arrangement method is the same as the connection principle of the embedded steel bar and the structure in the prior art. The original structure 20 is a load-bearing column in the original structure or a part that needs to be reserved in the building structure and is not dismantled. The internal steel bar 11-3 is a steel bar specially arranged in the hollow block. The number and arrangement position of the internal steel bar 11-3 are determined according to the design requirements of the reconstruction. The external embedded steel bar 11-1 and the internal steel bar 11-3 are in one-to-one corresponding connection. The internal steel bar 11-3 is arranged in the hollow block body 1 along the length direction of the hollow block body 1. The other end of the external embedded steel bar 11-1 is connected to one end of the internal steel bar 11-3 through the lap joint 11-2.

[0039] The lap joint 11-2 comprises a plurality of spacers 11-2-1. The thickness of the spacer 11-2-1 is thin, which is 2-5 mm. The spacer 11-2-1 provides a position for the clamping connection of the lap joint of the internal steel bar 11-3. The plurality of spacers 11-2-1 are uniformly arranged on the external embedded steel bar 11-1 along the outer circumferential direction of the external embedded steel bar 11-1. The length direction of each spacer 11-2-1 is the same as the length direction of the external embedded steel bar 11-1. The side of each spacer 11-2-1 facing the external embedded steel bar 11-1 is connected to the external embedded steel bar 11-1. Two adjacent spacers 11-2-1 and the outer wall of the external embedded steel bar 11-1 form a clamping groove 50. The plurality of clamping grooves 50 provide a plurality of connection positions for the internal steel bar 11-3. After the internal steel bar 11-3 is arranged in the hollow block body 1, the internal steel bar 11-3 is connected to one clamping groove 50. The lap joint is simplified, and the internal steel bar 11-3 is stably clamped in the clamping groove 50 after the lap joint. The connection between the external embedded steel bar 11-1 and the internal steel bar 11-3 is fastened and not easy to loosen, which is beneficial to the subsequent pouring process. The length of the clamping groove 50 is determined according to the design requirements and is not less than 1.25 times the outer diameter of the external embedded steel bar 11-1 or the internal steel bar 11-3. The length of the clamping groove 50 is not less than 300 mm. The groove width of the clamping groove 50 is matched with the outer diameter of the internal steel bar 11-3. When the docking steel bar assembly 11 is in the self-connection state, the internal steel bar 11-3 is clamped with the clamping groove 50 close to it.

[0040] The purpose of arranging the lap joint 11-2 on the external anchorage 11-1 in the embodiment is to expose the part of the lap joint 11-2 by the way of prefabricated anchorage, facilitate the stable lap of the inner steel bar 11-3 in the hollow block body 1, reduce the lap difficulty, form the lap joint 11-2 in the process of the inner steel bar 11-3 in the hollow block body 1 actively exposing the lap joint, and avoid the situation of the external anchorage 11-1 inserted into the hollow block body 1 to find the lap position.

The outer wall of the buckling cap 11-2-2 is uniformly distributed with a plurality of said spacers 11-2-1. Each spacer 11-2-1 has a groove 80 machined on the outer wall of each spacer 11-2-1 along the length direction of the spacer 11-2-1.

[0042] Further, the groove 80 is a gradually changing groove in depth. The distance from the middle part of the groove 80 to the upper side or the lower side of the groove 80 is sequentially increased, so as to form a center recess and a thickened groove body on both sides. The groove 80 is beneficial to the clamping and limiting fixing effect after the inner steel bar 11-3 is lapped, and the clamping groove 50 between the two opposite grooves 80 forms a clamping structure with a narrow top and a wide inside.
