Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an anchoring device for pre-embedded parts of tie bars for filling walls. Background Art

[0002] During the construction process, when building the infill wall, tie bars are needed to connect and fix it to the main structure frame to ensure that the infill wall is in a stable state.

[0003] The most commonly used traditional method for tie bars is the embedded rebar method, which involves drilling holes on the surface of the main structural frame after construction is completed. The rebar is then wrapped in embedded rebar glue to connect it to the main structural frame to enhance the bonding strength between the two.

[0004] However, drilling and rebar planting often results in problems such as insufficient drilling depth or incomplete hole cleaning, which can result in the tie bars not being tightly connected to the main structural frame, thus affecting the overall structural stability. Furthermore, the impact drill used for rebar planting can cause damage to the main structural frame during operation, thus affecting the load-bearing capacity of the main structural frame. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an anchoring device for embedded parts of tie bars in infill walls.

[0006] The technical solution of the utility model is as follows:

[0007] The bolt has a plurality of holes for passing through the outer rod and a plurality of holes for passing through the outer rod, and the plurality of holes are connected to the bolt.

[0008] Optionally, a threaded hole is formed on the right end surface of the inner rod, a threaded rod is welded to the left end surface of the outer rod, and the threaded rod is threadedly connected to the inside of the threaded hole.

[0009] Optionally, the diameter of the outer rod is consistent with the diameter of the inner rod.

[0010] Optionally, a hexagonal seat is welded to the right end surface of the outer rod, and the outer diameter of the hexagonal seat is smaller than the diameter of the outer rod.

[0011] Optionally, after the tie bar passes through the third through hole, the bending angle is ninety degrees to one hundred and eighty degrees.

[0012] All the above optional technical solutions can be combined arbitrarily, and the present utility model does not provide detailed descriptions of the structures after the combinations.

[0013] By means of the above solution, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model solves the problems of damage to the main structure frame caused by traditional anchoring and the loose adhesion of anchoring glue by embedding the inner rod in concrete and then fixing the tie bar to the outer rod. At the same time, it saves labor costs and reduces the difficulty of tie bar construction.

[0015] 2. When pouring concrete, secure the split anchor rod to the formwork to prevent displacement. To connect the tie bar to the outer rod, simply bend the tie bar appropriately and pass it through the second through-hole at the right end of the outer rod. Finally, tighten the outer nut to secure the tie bar. This ensures a secure connection between the tie bar and the outer rod. This simple operation eliminates the need for secondary welding, further improving construction efficiency.

[0024] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] See also Figure 1-6 The utility model provides an anchoring device for pre-embedded parts of tie bars for filling walls, comprising a template 1 and a multi-group split anchor rod 2, the split anchor rod 2 comprising an inner rod 21 and an outer rod 22, the outer rod 22 being threadedly connected to the right end of the inner rod 21, the template 1 being provided with a plurality of through holes 11 for passing through the outer rod 22, a steel plate 3 being movably connected to the left side of the template 1, the steel plate 3 being used to connect a plurality of inner rods 21 located on the same horizontal plane, the steel plate 3 being provided with a plurality of through holes 31 for passing through the inner rods 21, the right end face of the inner rod 21 being flush with the right side face of the steel plate 3 The outer side of the inner rod 21 is provided with an external threaded buckle 211, and the outer thread sleeve of the external threaded buckle 211 is provided with an inner nut 4, which abuts against the left side of the steel plate 3. The outer side of the outer rod 22 is provided with an external threaded buckle 221, and the outer thread sleeve of the external threaded buckle 221 is provided with an outer nut 5. The end of the outer rod 22 away from the inner rod 21 is penetrated by a through hole 222 for connecting the tie bar. The tie bar passes through the through hole 222, is bent and fixed by the external nut 5, and the external nut 5 is located between the template 1 and the through hole 222.

[0026] The utility model solves the problem of damage to the main structure frame caused by traditional anchoring and the loose adhesion of anchoring adhesive by pre-embedding the inner rod 21 in the concrete and then fixing the tie bar to the outer rod 22, while saving labor costs and reducing the construction difficulty of the tie bar. When pouring concrete, the split anchor rod 2 is fixed to the formwork 1 to ensure that the split anchor rod 2 will not shift during the pouring process. Specific operation method: insert the split anchor rod 2 into the through hole 11, and then use the steel plate 3 to connect the split anchor rods 2 located on the same horizontal plane. Then, screw in the inner nut 4 from the left end of the split anchor rod 2 so that it fits with the left side of the steel plate 3. Subsequently, screw in the outer nut 5 from the right end of the split anchor rod 2 so that it fits with the right side of the formwork 1. At this time, the split anchor rod 2 and the steel plate 3 are firmly fixed to the formwork 1 through the inner nut 4 and the outer nut 5. Then, the formwork 1 is set up and concrete is poured according to normal construction methods. After the concrete is cured and formed to the demoulding strength, the outer rod 22 is separated from the inner rod 21. At this time, the formwork 1 can be removed, and the inner rod 21, steel plate 3 and inner nut 4 are pre-embedded in the main structural frame. When building the infill wall, the outer rod 22 is first connected to the inner rod 21, and then the outer nut 5 is screwed into the outside of the outer rod 22 so that the outer nut 5 fits the steel plate 3. The tie bar is then bent and passed through the second through-hole 222 at the right end of the outer rod 22. Finally, the outer nut 5 is reversed to clamp the tie bar and secure it, thereby ensuring a stable connection between the tie bar and the outer rod 22.

[0027] It should be noted that when building the filling wall, the tie bars need to be aligned with the masonry joints. At this time, the masonry needs to be grooved in advance to provide sufficient placement space for the external nuts 5.

[0028] Specifically, the right end face of the inner rod 21 is flush with the right side face of the steel plate 3. The purpose of this is to separate the outer rod 22 from the inner rod 21 after the concrete has been cured and formed to reach the demolding strength, and then remove the outer rod 22 from the through hole 11. At this time, the formwork 1 is no longer restricted by the outer rod 22, making it easier to remove the formwork 1.

[0029] Specifically, the steel plate 3 is used to connect multiple sets of inner rods 21 located on the same horizontal plane. The purpose of this is to embed the steel plate 3 together with the inner rods 21 in the main structural frame, which can effectively improve its shear and tensile resistance, making it more resistant to external forces.

[0030] Furthermore, a threaded hole 212 is formed on the right end surface of the inner rod 21 , and a threaded rod 223 is welded to the left end surface of the outer rod 22 , and the threaded rod 223 is threadedly connected to the inside of the threaded hole 212 .

[0031] Specifically, the outer rod 22 is threadedly connected to the inner rod 21 through the threaded rod 223, which makes it possible to easily separate the outer rod 22 from the inner rod 21 when removing the template 1, thereby quickly removing the position restriction of the template 1 and facilitating the removal of the template 1.

[0032] Furthermore, the diameter of the outer rod 22 is consistent with the diameter of the inner rod 21 .

[0033] Specifically, the outer rod 22 and the inner rod 21 have the same diameter. This allows them to form a smooth, integrated structure when connected, allowing them to pass smoothly through the formwork 1. Preferably, the diameters of both the outer rod 22 and the inner rod 21 are greater than 10 mm. This not only enhances the load-bearing capacity of the overall structure but also significantly improves its resistance to bending and torsion. The outer rod 22 should be designed to be longer than 20 mm to ensure a secure connection with the tie bar. The inner rod 21 should be designed to be longer than 120 mm to maintain sufficient embedded length, thereby enhancing the stability of the structure.

[0034] Furthermore, a hexagonal seat 224 is welded to the right end surface of the outer rod 22 , and the outer diameter of the hexagonal seat 224 is smaller than the diameter of the outer rod 22 .

[0035] Specifically, the hexagonal seat 224 is provided so that construction workers can use a tool (such as a wrench) to grasp the hexagonal seat 224 and rotate it, thereby completing the disassembly and assembly of the outer rod 22. The outer diameter of the hexagonal seat 224 is smaller than the diameter of the outer rod 22, which facilitates the outer nut 5 to be installed from the right end of the outer rod 22 without interfering with the hexagonal seat 224.

[0036] Furthermore, after the tie bar passes through the third through hole 31, the bending angle is 90 degrees to 180 degrees.

[0037] Specifically, bending the tie bar can ensure a stable connection between the tie bar and the split anchor rod 2 .

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
