DETAILED DESCRIPTION
[0027] The specific embodiments of the utility model will be described below in combination with the drawings.
[0028] As Figure 1 shown, the utility model hollow block 4 independent type core column steel bar 5 positioning and fixing device, including fixed frame 1, connecting component 2 and limiting ring 3, limiting ring 3 is connected with fixed frame 1 through connecting component 2.
[0029] Among them, fixed frame 1 is the strip component, and its overall is right-angle structure, and the both ends of fixed frame 1 are hook 1-1 respectively, and hook 1-1 can be hung on the side wall of hollow block 4, since two hooks 1-1 are hung on two mutually perpendicular side walls respectively, so through two hooks 1-1, the utility model can be fixed on hollow block 4.
[0030] Hook 1-1 is specifically inverted U-shaped, and the size of hook 1-1 is adapted to the wall thickness of hollow block 4.
[0031] Connecting component 2 is long strip structure, and its overall is also corresponding right-angle structure with fixed frame 1, and the middle part of fixed frame 1 is located in connecting component 2.
[0032] The limiting ring 3 is located in the inside of the right angle of the fixed frame 1, and the limiting ring 3 is connected with the connecting component 2 through at least two positions, so that the structural strength and stability of the connection between the limiting ring 3 and the connecting component 2 can be improved.
[0033] The limiting ring 3 comprises an inner ring 3-1, an outer ring 3-2 and axial support strips 3-3, the outer ring 3-2 is directly connected with the inner side of the fixed component, the inner ring 3-1 and the outer ring 3-2 are connected through the axial support strips 3-3, and the same side of the inner ring 3-1 and the outer ring 3-2 is provided with an opening 3-5, and the opening 3-5 is located away from the connecting component 2. The core column steel bar 5 can enter the inner ring 3-1 through the opening 3-5.
[0034] The inner ring 3-1 and the outer ring 3-2 are concentric, the axial support strips 3-3 are uniformly distributed around the center of the inner ring 3-1 or the outer ring 3-2, and the part between the two axial support strips 3-3 on the inner ring 3-1 and the outer ring 3-2 is removed to form the opening 3-5.
[0035] In order to limit the core column steel bar 5 from being taken out of the inner ring 3-1, the width of the opening 3-5 at the inner ring 3-1 is generally smaller than the diameter of the core column steel bar 5, so that the axial support strips 3-3 on both sides are pried apart when the core column steel bar 5 passes through the opening 3-5, in order to facilitate the entry of the core column steel bar 5 and prevent damage to the limiting ring 3, part of the axial support strips 3-3 is replaced by a deformation compensation strip 3-4, generally the second axial support strip 3-3 close to the opening 3-5 is replaced by the deformation compensation strip 3-4.
[0036] The deformation compensation strip 3-4 has basically the same structure as the axial support strip 3-3, and a first U-shaped bending part 3-6 is arranged in the middle of the deformation compensation strip 3-4, when the core column steel bar 5 passes through the opening 3-5 to cause deformation of the limiting ring 3, the first U-shaped bending part 3-6 is contracted to adapt to the deformation.
[0037] Further, a second U-shaped bending part 3-7 is arranged on the outer ring 3-2, the second U-shaped bending part 3-7 faces the inside of the outer ring 3-2, and is symmetrically arranged on both sides of the opening 3-5, when the core column steel bar 5 passes through the opening 3-5 to cause deformation of the limiting ring 3, the second U-shaped bending part 3-7 also contracts to adapt to the deformation.
[0038] A plurality of non-axial limiting strips 3-8 are arranged on the inner side of the inner ring 3-1, the non-axial limiting strips 3-8 are deviated from the axis of the inner ring 3-1 or the outer ring 3-2 by a certain angle, when the core column steel bars 5 with different diameters enter the inner ring 3-1, the non-axial limiting strips 3-8 automatically adapt through swinging, and the core column steel bars 5 are ensured to be located in the center of the inner ring 3-1.
[0039] The non-axial limiting strips 3-8 on both sides of the opening 3-5 are symmetrical and both are inclined away from the opening 3-5, which facilitates the entry of the core column steel bar 5.
[0040] To prevent the core column steel bar 5 from coming out of the opening 3-5, flexible limiting blocks 3-9 are respectively set on both sides of the opening 3-5 of the inner ring 3-1. The inner sides of the flexible limiting blocks 3-9 gradually approach each other to form a figure-eight shape. When the core column steel bar 5 enters from the opening 3-5, it will open the two flexible limiting blocks 3-9. After the core column steel bar 5 enters the inner ring 3-1, the two flexible limiting blocks 3-9 will reset and block the opening 3-5.
[0041] The connecting component 2 and the fixing frame 1 can be an integral structure or a separate structure. When it is a separate structure, such as Figure 2 As shown, a fixing groove 2-1 is provided on the connecting component 2. The fixing groove 2-1 and the fixing frame 1 have the same right-angle structure, and the fixing frame 1 is placed in the fixing groove 2-1.
[0042] like Figure 3 As shown, in order to prevent the fixing bracket 1 from coming out of the fixing groove 2-1, a strip cover plate 2-2 is provided on the fixing groove 2-1, a snap-fit groove is provided on the side wall of the fixing groove 2-1, and a corresponding protrusion is provided on the side wall of the strip cover plate 2-2. When the strip cover plate 2-2 is fastened in the fixing groove 2-1, the protrusion is snapped into the snap-fit groove.
[0043] like Figure 4 As shown, when there is only one core column steel bar 5 inside the hollow block 4 core column, this utility model is used to fix the core column steel bar 5.
[0044] like Figure 5 As shown, when there are two core column steel bars 5 inside the core column of the hollow block 4, the two core column steel bars 5 are located at the diagonal position of the core column. The two utility models are respectively set at the diagonal position inside the hollow block 4 to fix the two core column steel bars 5 respectively.
[0045] The method of using this utility model is as follows:
[0046] Step 1: Positioning and laying out the lines, and binding the core column steel bar 5 to the main body reserved steel bar 5;
[0047] The second step is to lay two courses of bricks (400mm high) after laying the bricks. Then, use the limiting ring 3 of this utility model to hold the core column steel bar 5 in place, and tie the fixing frame 1 to the top of the block to position and fix the core column steel bar 5 to ensure that the core column steel bar 5 does not shift.
[0048] The third step is to pour the core column concrete, tamping it as you pour. When the concrete reaches the bottom of this utility model, remove the utility model. At this point, the core column steel bar 5 is fixed by the concrete below.
[0049] The fourth step, the second step, and the third step are cycled until the masonry is completed, and the utility model can be repeatedly used during the masonry process.
