Technical Field

[0001] The utility model belongs to the technical field of prefabricated wall positioning, in particular to a positioning tool fixture. Background Art

[0002] PC wall usually refers to prefabricated assembled concrete structural wall, which is a modern building wall form. It is a wall structure formed by prefabricating and curing the designed components in the factory, and then transporting them to the construction site. It is formed by mechanical lifting or combining it with cast-in-place concrete. It is usually composed of components prefabricated and maintained in the factory, and has high production efficiency and construction speed.

[0003] At present, during the PC wall hoisting construction, it is necessary to align the holes between the PC wall and the steel bars reserved on the base. The PC wall is prone to shaking after being hoisted, and the PC wall is prone to displacement when the steel bars are aligned, resulting in steel bar deformation and quality problems. On-site construction workers often use mirrors to lean over or squat to check, which poses a safety hazard and is prone to fatigue. Utility Model Content

[0004] The purpose of the utility model is to provide a positioning tool with a simple structure, which can align the embedded steel bars with the reserved holes of the wall, thus facilitating the installation of the wall.

[0005] The positioning tool fixture includes two vertically arranged vertical tubes, the upper ends of the vertical tubes are detachably connected to the first connecting tubes, a horizontal tube is horizontally arranged between the vertical tubes, and connecting parts are installed at both ends of the horizontal tubes to fix the horizontal tubes on the vertical tubes. Adjustment components for adjusting the distance between the two vertical tubes are provided on the first connecting tube and the horizontal tube, and angle irons are vertically arranged at the connections between the vertical tubes, the first connecting tubes and the horizontal tubes.

[0006] Furthermore, an insert pipe is vertically and independently installed in the upper end of the vertical pipe, and the insert pipe is respectively fixed to the two ends of the first connecting pipe. The vertical pipe and the insert pipe are both provided with through holes communicating with each other from front to back, and a pin is installed in the through hole.

[0007] Furthermore, the lower end of the vertical pipe is independently sleeved with a first sleeve, and the lower end of the first sleeve is horizontally fixed with a second connecting pipe.

[0008] Furthermore, a scale is provided on the vertical tube below the horizontal tube.

[0009] Furthermore, the adjustment assembly includes a second sleeve, and the first connecting pipe is divided into two halves after being cut in the middle. The two halves of the first connecting pipe are respectively inserted into the two ends of the second sleeve. Nuts are fixed at both ends of the second sleeve, and bolts that are threadedly matched with the nuts are installed in the nuts. After the bolts are inserted into the second sleeve, they are tightened on the first connecting pipe.

[0010] Furthermore, the connecting piece is in an "L"-shaped structure, one end of the connecting piece is fixed on the horizontal tube, and the other end of the connecting piece is provided with a threaded hole, in which a bolt threadedly matched with the threaded hole is passed through, and the bolt is tightened on the vertical tube after passing through the connecting piece.

[0011] Furthermore, when the first connecting pipe is aligned with its ground reference line, the upper end of the angle iron exceeds the embedded steel bar.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, two vertical pipes, a first connecting pipe and a horizontal pipe are spliced into a square frame structure, which is aligned with the baseline of the construction ground. Construction workers step on the square pipes to move the lifted wall into the square frame. Four angle irons wrap the four corners of the wall. Under the guidance and limitation of the angle irons, the wall is lowered vertically, and the embedded steel bars are aligned with the reserved holes of the wall, which is beneficial to the installation of the wall.

[0020] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0021] Example 1

[0022] A positioning tool tool described in this embodiment, such as Figures 1 to 5 As shown, it includes two vertically arranged vertical pipes 1, and the two vertical pipes 1 are vertically distributed left and right;

[0023] The upper end of the vertical pipe 1 is detachably connected to the first connecting pipe 4, which is horizontally arranged on the top of the vertical pipe 1. The upper ends of the two vertical pipes 1 are connected to the left and right ends of the first connecting pipe 4. After the PC wall is installed, the first connecting pipe 4 is removed from the vertical pipe 1 through the detachable connection between the vertical pipe 1 and the first connecting pipe 4, and the vertical pipe 1 is taken out from the outside of the PC wall. The first connecting pipe 4 and the vertical pipe 1 are reassembled and continued to be used;

[0024] A horizontal pipe 5 is horizontally arranged between the vertical pipes 1. The horizontal pipe 5 is horizontally arranged between the two vertical pipes 1. The left end of the horizontal pipe 5 is connected to the right side wall of the left vertical pipe 1, and the right end is connected to the left side wall of the right vertical pipe 1. The position of the horizontal pipe 5 is adjusted between the two vertical pipes 1 according to the thickness of the PC wall.

[0025] Connectors 12 are installed at both ends of the transverse tube 5 to fix the transverse tube 5 to the vertical tube 1. There are two connectors 12, which are fixed at both ends of the transverse tube 5. After the position of the transverse tube 5 is adjusted, the transverse tube 5 is fixed to the vertical tube 1 through the connectors 12 to prevent the transverse tube 5 from sliding during use.

[0026] The middle part of the first connecting pipe 4 is sleeved with a second sleeve 9, and the middle part of the first connecting pipe 4 is divided into two halves, the left and right halves of the first connecting pipe 4 are respectively inserted into the two ends of the second sleeve 9, the right end of the left half of the first connecting pipe 4 is inserted into the left end of the second sleeve 9, and the left end of the right half of the first connecting pipe 4 is inserted into the left end of the second sleeve 9. The two first connecting pipes 4 slide left and right along the length direction of the second sleeve 9, and the distance between the two vertical pipes 1 is adjusted according to the width of the PC wall; nuts 10 are fixed at both ends of the second sleeve 9, and bolts threadedly matched therewith are installed in the nuts 10. After the bolts penetrate the second sleeve 9, they are tightened on the first connecting pipe 4. By tightening the bolts, the bolts penetrate the second sleeve 9 and are tightened on the first connecting pipe 4, so that the positions of the two first connecting pipes 4 are fixed, avoiding the first connecting pipe 4 from being in use. The connecting pipe 4 is displaced; this paragraph constitutes an adjustment component for adjusting the spacing between the two vertical pipes 1. When the adjustment component is used, the depth of the two parts of the first connecting pipe 4 inserted into the second sleeve 9 is adjusted according to the width of the PC wall, and the distance between the two vertical pipes 1 is adjusted, thereby adjusting the distance between the left and right angle irons 3 to match walls of different widths. After the spacing adjustment is completed, the bolts are tightened, and the bolts are inserted into the second sleeve 9 and then tightened to the first connecting pipe 4 to fix the position of the first connecting pipe 4; of course, in the adjustment component, the horizontal pipe 5 is divided into left and right halves after being broken from the middle, and the second connecting pipe 6 is divided into left and right halves after being broken from the middle, both of which are equipped with the second sleeve 9. When adjusting the distance between the two vertical pipes 1, the first connecting pipe 4, the horizontal pipe 5 and the second connecting pipe 6 need to be adjusted synchronously to meet the use requirements;

[0027] Angle irons 3 are vertically provided at the connections between the vertical pipe 1, the first connecting pipe 4 and the horizontal pipe 5. There are four angle irons 3. The left end of the upper left corner angle iron 3 is fixed to the upper end of the right side wall of the left vertical pipe 1, and the upper end is attached to the left bottom end of the first connecting pipe 4. The left end of the lower left corner angle iron 3 is fixed to the right side wall of the left vertical pipe 1, and the lower end is attached to the top of the horizontal pipe 5. The right end of the upper right corner angle iron 3 is fixed to the upper end of the left side wall of the right vertical pipe 1, and the upper end is attached to the right bottom end of the first connecting pipe 4. The right end of the lower right corner angle iron 3 is fixed to the left side wall of the right vertical pipe 1, and the lower end is attached to the top of the horizontal pipe 5. The four corners of the PC wall are attached to the four angle irons 3. Under the guidance of the angle irons 3, the PC wall is vertically lowered, which is conducive to aligning the embedded steel bars with the reserved holes of the PC wall.

[0028] When this embodiment is used, the first connecting pipe 4 is spliced on the upper ends of the two vertical pipes 1, and the two vertical pipes 1, the first connecting pipe 4 and the horizontal pipe 5 are aligned with the baseline of the ground. The construction workers step on the first connecting pipe 4 or the horizontal pipe 5 to move the suspended PC wall into the formed frame. The four angle irons 3 fit the four corners of the PC wall. Under the guidance and limitation of the angle irons 3, the PC wall is vertically lowered, and the embedded steel bars are aligned with the reserved holes of the PC wall, which is beneficial to the installation of the PC wall. When the PC wall shakes during the descent process, the angle irons 3 will drive the two vertical pipes 1, the first connecting pipe 4 and the horizontal pipe 5 to move. The construction workers stop the descent of the PC wall in time through feedback from the soles of their feet to avoid the steel bars from being bent and ensure the construction quality.

[0029] In this embodiment, the length of the fixed end of the angle iron 3 is smaller than the other end of the angle iron 3. Figure 1 As shown, the horizontal sides of the two angle irons 3 on the left are fixed on the first connecting tube 4, which are the fixed ends of the angle irons 3. The horizontal sides of the two angle irons 3 on the right are fixed on the horizontal tube 5, which are the fixed ends of the angle irons 3. The length of the horizontal side of the angle iron 3 is greater than the length of the vertical side of the angle iron 3. The horizontal side of the angle iron 3 is attached to the long side of the PC wall, and the vertical side of the angle iron 3 is attached to the short side of the PC wall. The longer horizontal side increases the contact area with the long side of the PC wall, thereby improving the guiding and limiting effect on the wall.

[0030] Example 2

[0031] This embodiment further illustrates the technology. Figure 5 As shown, the upper ends of the vertical tubes 1 are vertically and independently installed with insert tubes 11. There are two insert tubes 11, which are vertically installed in the corresponding vertical tubes 1 respectively. The insert tubes 11 are vertically installed in the vertical tubes 1 and slide up and down along the length direction of the vertical tubes 1.

[0032] The cannula 11 is fixed to both ends of the first connecting tube 4, the upper end of the left cannula 11 is fixed to the left end of the first connecting tube 4, and the upper end of the right cannula 11 is fixed to the right end of the first connecting tube 4;

[0033] Both the vertical pipe 1 and the inserting pipe 11 are provided with through holes communicating with each other from front to back. A latch 2 is passed through the through hole, and the first connecting pipe 4 is fixed to the upper end of the vertical pipe 1 through the latch 2 .

[0034] When using this embodiment, the two insertion tubes 11 are respectively inserted into the corresponding vertical tubes 1. When the upper end of the vertical tube 1 is against the first connecting tube 4, the vertical tube 1 is aligned with the through holes on the insertion tube 11. The pin 2 is inserted into the two through holes to fix the first connecting tube 4 to the upper end of the vertical tube 1.

[0035] Example 3

[0036] This embodiment further illustrates the technology. Figure 1As shown, the lower end of the vertical pipe 1 is independently sleeved with a first sleeve 7, which is sleeved on the lower end of the vertical pipe 1 and moves up and down along the length direction of the vertical pipe 1;

[0037] The second connecting pipe 6 is horizontally fixed to the lower end of the first sleeve 7 , the lower end of the left first sleeve 7 is fixed to the left end of the second connecting pipe 6 , and the lower end of the right first sleeve 7 is fixed to the right end of the second connecting pipe 6 .

[0038] When this embodiment is used, if there is no steel bar center line or wall edge line at the construction site, by adjusting the second connecting pipe 6 to align with the control line, it can replace the secondary marking and realize the rapid positioning of the box;

[0039] In this embodiment, a nut is welded on the side of the first sleeve 7, and a bolt is installed in the nut. After the bolt is tightened, it is inserted into the first sleeve 7, pressing against the vertical pipe 1, and fixing the first sleeve 7 to the lower end of the vertical pipe 1 to prevent the first sleeve 7 from sliding along the vertical pipe 1.

[0040] like Figure 1 As described, a scale 8 is provided on the vertical pipe 1 below the horizontal pipe 5. The scale 8 facilitates construction workers to visually observe the position of the second connecting pipe 6 and further calibrate the position of the square frame so that the steel bars can be accurately inserted into the reserved holes.

[0041] In this embodiment, scales 8 are provided on both the left and right halves of the first connecting pipe 4 , and the scales 8 facilitate construction workers to adjust the distance between the two vertical pipes 1 according to the width of the wall.
