[0026] The specific embodiments of the utility model are described below in combination with the drawings.
[0027] As Figure 1 , Figure 2 and Figure 5 shown, the utility model is a kind of hollow block 6 frame type core column steel bar 7 positioning and fixing device, its structure mainly includes outer frame 1, connecting frame 2, positioning ring 3, inner side limit card 4 and outer side limit card 5 etc.
[0028] Among them, outer frame 1 is rectangular frame structure, its outer edge is consistent with the edge of the hollow hole of hollow block 6, so that outer frame 1 can be placed into the hollow hole of hollow block 6, and the periphery of outer frame 1 is attached to the inner wall of the hollow hole of hollow block 6.
[0029] Several outer side limit cards 5 that extend outward are provided at the upper portion of outer frame 1, and the outer side limit card 5 is used to overlap on the top of hollow block 6, so as to prevent outer frame 1 from moving downward in the hollow hole of hollow block 6.
[0030] Meanwhile, several inner side limit cards 4 are provided at the lower surface edge of outer frame 1, and the inner side limit card 4 is used to be connected on the inner wall of the hollow hole of hollow block 6, and the inner side limit card 4 is extruded into the hollow hole of hollow block 6, to provide horizontal direction pressure inside the hollow hole of hollow block 6, further strengthen the fixation of outer frame 1 in the hollow hole of hollow block 6, prevent horizontal displacement and upward displacement of outer frame 1. Outer frame 1 can be stably fixed in the hollow hole of hollow block 6 by inner side limit card 4 and outer side limit card 5.
[0031] And connecting frame 2 is located in outer frame 1, and positioning ring 3 is located on connecting frame 2, and positioning ring 3 is fixedly connected with outer frame 1 by connecting frame 2, when outer frame 1 is fixed, the position of positioning ring 3 and core column steel bar 7 located in the fixed ring is also fixed.
[0032] Depending on the number of core column steel bars 7 inside the core column, this utility model can have two structures. The specific difference between the two structures lies in the structure of the connecting frame 2.
[0033] The first structure, such as Figure 1 , Figure 3 As shown, when the core column is at full height, two core column steel bars 7 need to be placed diagonally inside the hollow hole of the hollow block 6. The connecting frame 2 is in the shape of a straight line. The connecting frame 2 connects the two diagonals of the outer frame 1. A positioning ring 3 is set at each end of the connecting frame 2. The positions of the two positioning rings 3 correspond to the positions of the two core column steel bars 7. When the core column steel bars 7 are inserted into the two positioning rings 3, the positions of the two core column steel bars 7 can be positioned and fixed.
[0034] The second structure, such as Figure 2 , Figure 4 As shown, when the core column is not continuous, since only one core column steel bar 7 needs to be placed in the center of the hollow hole of the hollow block 6, the connecting frame 2 is cross-shaped. The four ends of the cross-shaped connecting frame 2 are connected to the four sides of the outer frame 1 respectively. The positioning ring 3 is located in the center of the cross-shaped connecting frame 2. When the core column steel bar 7 is inserted into the positioning ring 3, the position of the core column steel bar 7 can be positioned and fixed.
[0035] In one embodiment of this utility model, there are two outer limiting cards 5, and the two outer limiting cards 5 are located on both sides of the outer frame 1. The body of the outer limiting card 5 is a horizontal plate that extends to the edge of the outer frame 1. When the outer frame 1 is placed in the hollow hole of the hollow block 6, the horizontal plate overlaps the top of the side wall of the hollow block.
[0036] Furthermore, a downwardly extending baffle is provided at the outer end of the outer limiting card 5. The baffle can assist in fixing the outer frame 1 on the one hand, and facilitate the removal of the outer frame 1 from the hollow hole of the hollow block 6 on the other hand. The position of the outer limiting card 5 can correspond to the position of the inner limiting card 4, and the inner limiting card 4 and the outer limiting card 5 can simultaneously clamp the side wall of the hollow block 6.
[0037] In one embodiment of this utility model, there are four inner limiting cards 4, which are located on the four sides of the outer frame 1 respectively.
[0038] Further, the inner side limiting clamping 4 is inclinedly protruded from the outer edge of the outer frame 1 to the outer side, and the lower end of the inner side limiting clamping 4 is bent to the inner side. When the outer frame 1 is placed in the hollow hole of the hollow block 6, the bent lower end of the inner side limiting clamping 4 facilitates the entry of the inner side limiting clamping 4. As the outer frame 1 gradually enters the hollow hole of the hollow block 6, the side wall of the hollow block 6 extrudes the protruding part of the inner side limiting clamping 4, so that the inner side limiting clamping 4 is clamped on the side wall of the hollow block 6.
[0039] The use method of the utility model is as follows: positioning and placing a wire, first planting a steel bar at the bottom, and binding and connecting the core column steel bar 7 with the steel bar; then building the hollow block 6, after building a construction section height (400-500mm), the positioning ring 3 of the utility model is sleeved on the core column steel bar 7, and the outer frame 1 of the utility model is fixed at the top of the hollow hole of the hollow block 6, so that the core column steel bar 7 is positioned and fixed, and the displacement of the core column steel bar 7 is ensured; pouring core column concrete, pouring and tamping at the same time, when pouring the outer frame 1 and the inner side limiting clamping 4 below, the utility model is taken out from the hollow block 6, at this time, the core column is fixed by the lower concrete; repeating the above steps, placing the core column steel bar 7 along with building, and binding and overlapping the upper and lower core column steel bars 7, until building is completed, and the utility model can be recycled and reused in the building process.
