Description

Technical Field

[0001] The present application relates to the technical field of building materials, and in particular to an assembled formed steel bar skeleton. Background Art

[0002] The steel frame is commonly known as the steel cage. Its main function is the same as the stress of the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It plays a restraining role on the pile concrete, so that it can withstand a certain axial tension.

[0003] Most of the existing steel cages are made of multiple vertical steel bars and horizontal stirrups. When splicing, first use steel wire to connect the vertical steel bars one by one with a stirrup, then put several stirrups on the vertical steel bars, and then connect the stirrups to the steel bars. Repeat the above process to complete the splicing of the steel cage.

[0004] In actual use, since the steel cage itself is large in size, the vertical steel bars are thicker and heavier, and the vertical steel bars and stirrups are tied with steel wire, the vertical steel bars will be subjected to stress when the steel cage is transported and put into use, which will cause the steel wire used to connect the vertical steel bars and stirrups to loosen, causing the entire steel cage to tilt, thereby affecting the subsequent construction quality. Utility Model Content

[0005] The purpose of the present application is to solve the problem in the above background technology that the stress on the vertical steel bars will cause the steel wires used to connect the vertical steel bars and stirrups to loosen, thereby causing the entire steel cage to tilt. The present application provides an assembled formed steel frame.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] An assembled formed steel bar skeleton comprises a base, the base is provided with a plurality of connection holes, a plurality of steel bars are arranged inside the connection holes, the steel bars are threadedly connected to the base, a fixing frame is sleeved on the steel bars, the fixing frame is provided with a plurality of insertion holes, the fixing frame is sleeved on the steel bars through the insertion holes, and a limiting structure is arranged between the fixing frame and the steel bars.

[0008] By adopting the above technical solution, when splicing the steel cage, several steel bars are connected to the base, and then the fixing frame is set on the steel bars, and the fixing frame is restricted by the connection restriction structure, and then several fixing frames are sequentially set on the steel bars to complete the installation of the steel cage. By setting the fixing frame in conjunction with the restriction structure, the deformation of the steel cage after being stressed can be reduced, and the quality of the steel cage can be improved.

[0009] Furthermore, the limiting structure includes a fixing column threadedly connected to the fixing frame, the fixing column extends into the insertion hole, the inner wall of the insertion hole is provided with a movable groove, the end of the fixing column is rotatably connected to a limiting plate, the limiting plate contacts the steel bar, and both ends of the limiting plate are in conflict with the inner wall of the movable groove.

[0010] By adopting the above technical solution, the fixing frame and the steel bars can be fixed by utilizing the limiting structure, and the fixing effect is good, thereby reducing looseness.

[0011] Furthermore, the limiting plate is in an arc shape, and an anti-slip bump is fixed to a side of the limiting plate away from the fixing column, the surface of the anti-slip bump is a rough surface, and the anti-slip bump is in contact with the steel bar.

[0012] By adopting the above technical solution, the friction between the limiting block and the steel bar can be increased by using the anti-slip protrusions with rough surfaces, thereby improving the connection effect between the fixing frame and the steel bar.

[0013] Furthermore, an embedding groove is provided on the side surface of the fixing frame, and one end of the fixing column away from the limiting plate is located inside the embedding groove.

[0014] By adopting the above technical solution, the protrusions on the surface of the fixing frame can be reduced by embedding the groove, which makes subsequent construction more convenient.

[0015] Furthermore, the inner wall of the insertion hole is provided with two symmetrically arranged fixing grooves, and two fixing spring sheets are fixed inside the fixing grooves. The fixing spring sheets are elastic metal strips, and the fixing spring sheets are in contact with the steel bars.

[0016] By adopting the above technical solution, the fixing frame can be fixed in advance by using the fixing spring sheet, which is convenient for subsequent fixing.

[0017] Furthermore, a reinforcement column is threadedly connected to the fixing frame, an adjustment column is threadedly connected inside the reinforcement column, and an end of the adjustment column is in conflict with the fixing frame at its upper end.

[0018] Furthermore, a screwing ring is fixed on the adjusting column, and the surface of the screwing ring is a rough surface.

[0019] By adopting the above technical solution, the adjusting column can be adjusted conveniently by rotating the screwing ring, and the screwing ring with a rough surface can increase the friction force.

[0020] Furthermore, a reinforcing protrusion is fixed on the fixing frame, and an injection hole is opened on the fixing frame.

[0021] By adopting the above technical solution, the contact area between the concrete and the steel reinforcement frame can be increased by utilizing the reinforcement protrusions and the injection holes, thereby improving the stability between the steel cage and the building.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] 1. In this application, when splicing the steel cage, the fixing frame is put on the steel bar, and the position of the fixing frame is adjusted. Then, the fixing column is twisted with existing wrenches and other tools to move the fixing column toward the steel bar. When moving, the limiting plate is stressed. At the same time, the limiting plate is restricted by the movable groove and moves toward the position of the steel bar, and resists the steel bar, thereby fixing the fixing frame on the steel bar. The fixing frame cooperates with the limiting structure to reduce the looseness of the steel bar when it is stressed, reduce the deformation of the steel cage, improve the quality of the steel cage, and facilitate subsequent construction.

[0024] 2. In the present application, when the wall columns are cast after the steel bar holes are put into use, the concrete contacts the added bumps and flows downward through the injection holes, thereby increasing the contact area between the concrete and the steel bar skeleton, making the concrete more integral after solidification and improving the strength of the entire concrete structure.

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The embodiment of the present application discloses an assembled formed steel bar skeleton.

[0034] Reference Figure 1 and Figure 2 A prefabricated formed steel bar skeleton includes a base 1, a plurality of connecting holes are opened on the base 1, a plurality of steel bars 2 are arranged inside the connecting holes, the steel bars 2 are threadedly connected to the base 1, a fixing frame 3 is sleeved on the steel bars 2, a plurality of insertion holes are opened on the fixing frame 3, the fixing frame 3 is sleeved on the steel bars 2 through the insertion holes, and a limiting structure is arranged between the fixing frame 3 and the steel bars 2.

[0035] When splicing the steel bar cage 2, place the base 1 on the ground, then connect several steel bars 2 with threads opened in advance to the connection holes on the base 1, then connect the fixing holes on the fixing frame 3 to several steel bars 2, so that the fixing frame 3 is set on the steel bar 2, and then the fixing frame 3 is restricted by the connection restriction structure, and then several fixing frames 3 are successively set on the steel bar 2, and the spacing is adjusted to fix them, and the installation of the steel bar cage 2 is completed. The fixing frame 3 cooperates with the restriction structure to reduce the looseness of the steel bar 2 when it is stressed, reduce the deformation of the steel bar cage 2, improve the quality of the steel bar cage 2, and facilitate subsequent construction.

[0036] Reference Figure 2 and Figure 3 The limiting structure includes a fixing column 4 threadedly connected to the fixing frame 3, the fixing column 4 extends into the insertion hole, the inner wall of the insertion hole is provided with a movable groove 5, the end of the fixing column 4 is rotatably connected with a limiting plate 6, the limiting plate 6 is in contact with the steel bar 2, and the two ends of the limiting plate 6 are in conflict with the inner wall of the movable groove 5.

[0037] The limiting plate 6 is arc-shaped, and an anti-skid protrusion 7 is fixed to the side of the limiting plate 6 away from the fixing column 4 . The surface of the anti-skid protrusion 7 is a rough surface, and the anti-skid protrusion 7 is in contact with the steel bar 2 .

[0038] In addition, an embedding groove 8 is opened on the side of the fixing frame 3 , and one end of the fixing column 4 away from the limiting plate 6 is located inside the embedding groove 8 .

[0039] After the fixing frame 3 is sleeved on the steel bar 2, the position of the fixing frame 3 is adjusted, and then the fixing column 4 is screwed with an existing wrench or other tool to move the fixing column 4 toward the direction of the steel bar 2. During the movement, the limiting plate 6 is subjected to force, and the limiting plate 6 is restricted by the movable groove 5 to move toward the position of the steel bar 2 and resist the steel bar 2, thereby fixing the fixing frame 3 on the steel bar 2. The fixing frame 3 can be restricted and fixed by the limiting structure, which is more convenient. At the same time, the fixing column 4 cooperates with the limiting block provided with the anti-slip protrusion 7 to improve the connection firmness between the fixing frame 3 and the steel bar 2, and after the fixing is completed, the screw head of the fixing column 4 is in the embedded groove 8, thereby reducing the protrusion on the surface of the fixing frame 3.

[0040] Reference Figure 4The inner wall of the insertion hole is provided with two symmetrically arranged fixing grooves 14 , and two fixing spring pieces 15 are fixed inside the fixing grooves 14 . The fixing spring pieces 15 are elastic metal strips, and the fixing spring pieces 15 are in contact with the steel bars 2 .

[0041] When the fixing frame 3 is put on the steel bar 2, the fixing spring piece 15 will be in conflict with the steel bar 2, and the fixing spring piece 15 will be in conflict with the steel bar 2. Then the fixing column 4 can be used to fix the fixing frame 3. The fixing spring piece 15 can be used to pre-fix the fixing frame 3 on the steel bar 2, and the operator does not need to drag the fixing frame 3 with his hands all the time, which is more convenient.

[0042] A reinforcing column 9 is threadedly connected to the fixing frame 3 , and an adjusting column 10 is threadedly connected inside the reinforcing column 9 , and an end of the adjusting column 10 is in conflict with the fixing frame 3 at its upper end.

[0043] After the fixing frame 3 is fixed in a suitable position, the reinforcement column 9 is connected to the fixing frame 3, and then the adjustment column 10 is twisted to extend the adjustment column 10 until the adjustment column 10 contacts the fixing frame 3 at its upper end. The use of the reinforcement column 9 and the adjustment column 10 can increase the support force between two adjacent fixing frames 3, thereby reducing the position deviation of the fixing frame 3 caused by the force on the steel bar 2.

[0044] Reference Figure 1 and Figure 5 A screwing ring 11 is fixed on the adjusting column 10, and the surface of the screwing ring 11 is a rough surface.

[0045] When rotating the adjusting column 10 , the adjusting column 10 can be rotated by holding the screw ring 11 with the rough groove surface, which can make the rotation of the adjusting column 10 easier and improve convenience.

[0046] Reference Figure 1 and Figure 5 A reinforcing protrusion 12 is fixed on the fixed frame 3, and an injection hole 13 is opened on the fixed frame 3.

[0047] When pouring the wall column, the concrete contacts the added protrusions and flows downward through the injection holes 13, thereby increasing the contact area between the concrete and the steel bar 2 skeleton, making the concrete more integrated after solidification and improving the strength of the entire concrete structure.

[0048] Working principle: when splicing the steel bar 2 cage, place the base 1 on the ground, then connect several steel bars 2 with threads opened in advance to the connecting holes on the base 1, and then connect the fixing holes on the fixing frame 3 to several steel bars 2, so that the fixing frame 3 is sleeved on the steel bars 2. After the fixing frame 3 is sleeved on the steel bars 2, adjust the position of the fixing frame 3, and then use existing wrenches and other tools to screw the fixing column 4, so that the fixing column 4 moves toward the direction of the steel bars 2. When moving, the limiting plate 6 will be subjected to force. At the same time, the limiting plate 6 will be restricted by the movable groove 5 and move toward the position of the steel bars 2, and resist the steel bars 2, so that the fixing frame 3 is fixed on the steel bars 2;

[0049] After the fixing frame 3 is fixed in a suitable position, the reinforcement column 9 is connected to the fixing frame 3, and then the adjustment column 10 is twisted to extend the adjustment column 10 until the adjustment column 10 conflicts with the fixing frame 3 at its upper end. The use of the reinforcement column 9 and the adjustment column 10 can increase the support force between two adjacent fixing frames 3, reduce the position deviation of the fixing frame 3 caused by the force on the steel bar 2, and complete the splicing of the steel bar 2 cage.
