Description

Technical Field

[0001] The utility model relates to the technical field of building construction inspection, and particularly relates to a simple device for detecting the perpendicularity of concrete wall and column templates. Background Technique

[0002] In building construction, after the formwork support of the wall and column is completed, it is necessary to detect the perpendicularity of the formwork. If there is a large deviation in the perpendicularity of the formwork, the wall and column formwork can be corrected in time, which can avoid the problem that the cast wall and column are unqualified due to the deviation in perpendicularity, thus avoiding large economic losses caused by rework.

[0003] The overall shape of the existing formwork perpendicularity detection device is a "C" shape. For example, a portable tool for rapid measurement of formwork perpendicularity disclosed in Chinese Patent CN218380830U can reduce the length of the device by folding two connecting rods through hinges when not in use, which is convenient for storage. However, this folding method has the following defects when storing:

[0004] After the device is folded, it is in an L shape. Therefore, when placed on the ground in the warehouse, it occupies a large area, and it is very easy to press on this device when placing other items, resulting in the device being bent and affecting subsequent use. Content of the Utility Model

[0005] The purpose of the utility model aims to solve at least one of the technical defects described in the background technique.

[0006] For this reason, an object of the utility model is to propose a simple device for detecting the perpendicularity of concrete wall and column templates, aiming to solve the problems that when the portable tool for rapid measurement of formwork perpendicularity in the prior art is not in use, it occupies a large area and is easily damaged.

[0007] To achieve the above object, an embodiment of one aspect of the utility model provides a simple device for detecting the perpendicularity of concrete wall and column templates, including a vertical rod, a suspension assembly, a plumb bob, and a measurement assembly; one side of the top and bottom of the vertical rod is provided with a threaded hole, and bolts for fixing the suspension assembly and the measurement assembly are threadedly connected in the two threaded holes; the suspension assembly includes a first socket, a first positioning hole is provided on the rear side of the first socket, an upper cross bar is fixedly connected to the left side of the first socket, a suspension beam is fixedly connected to the right side of the first socket, the top of the plumb bob is fixedly connected with a suspension line, and the plumb bob is connected to the suspension beam through the suspension line; the measurement assembly includes a second socket, a second positioning hole is provided on the rear side of the second socket, a lower cross bar is fixedly connected to the left side of the second socket, a measurement rod is fixedly connected to the right side of the second socket, and scale lines are provided on the surface of the measurement rod.

[0008] The beneficial effects are as follows: the first and second sleeves are respectively fitted onto the top and bottom of the vertical rod, and then two bolts are threaded through the first and second positioning holes and threaded into the threaded holes at the top and bottom of the vertical rod to fix the suspension assembly and measuring assembly. The bolts do not need to be tightened, so no tools are required for operation. When not in use, the two bolts can be unscrewed to remove the suspension assembly and measuring assembly. Therefore, disassembly and assembly are simple, and the space occupied after disassembly and assembly is small and it is not easily damaged by pressure.

[0009] In a preferred embodiment, a first U-shaped groove with its opening facing downwards is provided on the front side of the first sleeve corresponding to the position of the first positioning hole, and a second U-shaped groove with its opening facing upwards is provided on the front side of the second sleeve corresponding to the position of the second positioning hole.

[0010] Furthermore, one end of the bolt is fixedly connected to a positioning post, the diameter of which is equal to the diameter of the first positioning hole and the second positioning hole.

[0011] The beneficial effects are as follows: By connecting the bolts into the threaded holes, the positioning pins are also located within the threaded holes. When installing the suspension assembly and measuring assembly, the first and second sleeves are respectively placed on the top and bottom ends of the vertical rod, and the U-shaped grooves on the two sleeves are respectively fitted onto the bolt surfaces. Then, the two bolts are tightened, and the positioning pins on the two bolts extend from the threaded holes and insert into the two positioning holes, thus completing the installation of the suspension assembly and measuring assembly. When disassembling, the two bolts are loosened, allowing the positioning pins to be pulled out of the positioning holes, and the suspension assembly and measuring assembly can be removed. The bolts do not need to be removed from the threaded holes, thus avoiding the problem of bolt loss.

[0012] In a preferred embodiment, the top of the suspension beam has a through hole extending through its bottom, and one side of the suspension beam has a notch communicating with the through hole. A limiting block is fixedly connected to the top of the suspension wire. The diameter of the limiting block is larger than the diameter of the through hole, and a limiting groove is formed at the position on the top of the suspension beam corresponding to the through hole. The limiting block is inserted into the limiting groove.

[0013] The beneficial effects are as follows: the suspension line is inserted into the through hole through the notch, and the weight of the plumb bob pulls down the limiting block. The limiting block is inserted into the limiting groove, and the installation of the plumb bob is completed. Therefore, it is convenient to install and remove the plumb bob, and further improves the efficiency of the installation and removal of the device.

[0014] In a preferred embodiment, a groove is provided on the right side of the vertical rod, and a cylindrical spirit level is installed inside the groove. The straight line of the cylindrical spirit level is perpendicular to the plane containing the vertical rod, the upper horizontal rod, and the lower horizontal rod.

[0015] The beneficial effect is as follows: When inspecting a cylindrical template, after the ends of the two horizontal bars abut against the outer arc surface of the cylindrical template, the vertical bar is rotated with the upper horizontal bar as the origin, so that the bubble in the cylindrical level is located in the middle. Then, by observing the position of the plumb line and the scale line on the measuring rod, the verticality of the cylindrical template can be accurately obtained, thus facilitating the inspection of the verticality of the cylindrical template.

[0016] In a preferred embodiment, a limiting rod symmetrical to the measuring rod is fixedly connected to the right side of the second sleeve, and the gap between the measuring rod and the limiting rod corresponds to the through hole above.

[0017] The beneficial effects are as follows: When inspecting a cylindrical template, after the ends of the two horizontal bars abut against the outer arc surface of the cylindrical template, the vertical bar is rotated with the upper horizontal bar as the origin. The position of the plumb line between the measuring rod and the limiting rod is observed. When the plumb line is located on the center line of the gap between the measuring rod and the limiting rod, the position of the plumb line and the scale line on the measuring rod are observed to obtain the verticality of the cylindrical template, thus facilitating the monitoring of the verticality of the cylindrical template.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] This invention provides a simple device for detecting the verticality of concrete wall and column formwork.

[0031] Example 1:

[0032] like Figure 1 As shown, it includes a vertical rod 1, a suspension assembly 2 mounted on the top of the vertical rod 1 by bolts 12, a plumb bob 3, and a measuring assembly 4 mounted on the bottom of the vertical rod 1 by bolts 12.

[0033] like Figure 2-3As shown, the suspension assembly 2 includes a first sleeve 21, a first positioning hole 22 is provided on the rear side of the first sleeve 21, and a first U-shaped groove 23 with its opening facing downward is provided on the front side of the first sleeve 21 at the position corresponding to the first positioning hole 22. A threaded hole 11 corresponding to the first positioning hole 22 is provided on one side of the top end of the vertical rod 1, and the bolt 12 is threaded into the inside of the threaded hole 11. The first sleeve 21 is inserted downward from the top end of the vertical rod 1, and the first U-shaped groove 23 is fitted on the outer surface of the bolt 12 to limit the first sleeve 21. A positioning pin 13 is fixedly connected to one end of the bolt 12. When the bolt 12 is tightened, the positioning pin 13 extends out from the threaded hole 11 and inserts into the first positioning hole 22, thereby fixing the suspension assembly 2.

[0034] like Figure 3-4 As shown, an upper crossbar 24 is welded and fixed to the left side of the first sleeve head 21, and a suspension beam 25 is welded and fixed to the right side of the first sleeve head 21. A through hole 26 is opened at the top of the suspension beam 25, penetrating through its bottom. A notch 27 is opened on one side of the suspension beam 25, communicating with the through hole 26. A suspension line 31 is fixedly connected to the top of the plumb bob 3. A limiting block 32 is fixedly connected to the top of the suspension line 31. The suspension line 31 passes through the notch 27 into the through hole 26. The diameter of the limiting block 32 is larger than the diameter of the through hole 26, so that the limiting block 32 rests on the top of the suspension beam 25, which can support the plumb bob 3. A limiting groove 28 is opened at the position of the top of the suspension beam 25 corresponding to the through hole 26. The limiting block 32 is inserted into the limiting groove 28, which can prevent the limiting block 32 from sliding during use, causing the suspension line 31 to slide out from the notch 27 and causing the plumb bob 3 to fall.

[0035] like Figure 2 and Figure 5 As shown, the measuring component 4 includes a second sleeve 41, a second positioning hole 42 is provided on the rear side of the second sleeve 41, a second U-shaped groove 43 with an upward opening is provided on the front side of the second sleeve 41 corresponding to the second positioning hole 42, and a threaded hole 11 corresponding to the second positioning hole 22 is provided on one side of the bottom end of the vertical rod 1, and a bolt 12 is threaded into the threaded hole 11. The fixing method of the measuring component 4 is the same as that of the suspension component 2, and will not be described in detail.

[0036] like Figure 5 As shown, a lower crossbar 44 is welded and fixed to the left side of the second sleeve head 41, and a measuring rod 45 is welded and fixed to the right side of the second sleeve head 41. The surface of the measuring rod 45 is provided with scale lines 46.

[0037] The working principle of this embodiment is as follows: When in use, hold the vertical rod 1 and place the ends of the upper horizontal rod 24 and the lower horizontal rod 44 away from the vertical rod 1 against the outside of the concrete wall column formwork. The plumb bob 3 hangs down naturally. Then observe the position of the plumb line 31 corresponding to the scale line 46 on the measuring rod 45, so as to determine the verticality of the concrete wall formwork. When not in use, remove the limiting block 32 from the limiting groove 28, and then remove the plumb line 31 from the notch 27 to complete the removal of the plumb bob 3. Loosen the upper and lower bolts 12 so that the two positioning columns 13 are disengaged from the first positioning hole 22 and the second positioning hole 42 respectively. Then the suspension component 2 and the measuring component 4 can be removed. Thus, the vertical rod 1, the suspension component 2 and the measuring component 4 occupy a small area on the ground and are not easily damaged.

[0038] The surface of the concrete cylindrical formwork is curved. Therefore, when measuring the verticality of the cylindrical formwork, it is necessary to ensure that the plane containing the vertical rod 1, the upper horizontal rod 24, and the lower horizontal rod 44 is perpendicular to the horizontal plane to ensure that the measured verticality is accurate. Therefore, in order to facilitate the detection of the verticality of the cylindrical formwork, this application proposes Embodiment Two:

[0039] like Figure 6 As shown, based on Embodiment 1, a groove 14 is provided on the right side of the vertical rod 1, and a cylindrical spirit level 15 is installed inside the groove 14. The straight line of the cylindrical spirit level 15 is perpendicular to the plane containing the vertical rod 1, the upper horizontal rod 24 and the lower horizontal rod 44.

[0040] The working principle of this embodiment is as follows: When detecting the verticality of the cylindrical template, the end of the upper horizontal bar 24 away from the vertical bar 1 is placed against the outside of the template. Then, the vertical bar 1 is rotated with the upper horizontal bar 24 as the origin. By observing the bubble in the cylindrical level 15, when the bubble is located in the middle of the cylindrical level 15, the lower horizontal bar 44 is moved towards the template so that the end of the lower horizontal bar 44 is against the outside of the cylindrical template. Then, the verticality of the cylindrical template is obtained by using the plumb line 31 to correspond to the scale line 46 on the measuring rod 45. Since the bubble in the cylindrical level 15 is still in the middle at this time, the plane containing the vertical bar 1, the upper horizontal bar 24 and the lower horizontal bar 44 is perpendicular to the horizontal plane, so the measured verticality is accurate.

[0041] The surface of the concrete cylindrical formwork is curved. Therefore, when measuring the verticality of the cylindrical formwork, it is necessary to ensure that the plane containing the vertical rod 1, the upper horizontal rod 24, and the lower horizontal rod 44 is perpendicular to the horizontal plane to ensure that the measured verticality is accurate. Therefore, in order to facilitate the detection of the verticality of the cylindrical formwork, this application proposes Embodiment 3:

[0042] like Figure 7As shown, based on Embodiment 1, a limiting rod 47 symmetrical to the measuring rod 45 is welded and fixed to the right side of the second head 41, and the gap between the measuring rod 45 and the limiting rod 47 corresponds to the through hole 26 above.

[0043] The working principle of this embodiment is as follows: In use, the end of the upper horizontal bar 24 away from the vertical bar 1 is placed against the outside of the template. Then, the vertical bar 1 is rotated with the upper horizontal bar 24 as the origin. When the suspension line 31 is between the measuring rod 45 and the limiting rod 47, the lower horizontal bar 44 is moved towards the template so that the end of the lower horizontal bar 44 is against the outside of the cylindrical template. Then, the verticality of the cylindrical template is obtained by corresponding the scale line 46 on the measuring rod 45 with the suspension line 31. Since the suspension line 31 is located between the measuring rod 45 and the limiting rod 47 at this time, the suspension line 31, the vertical bar 1, the upper horizontal bar 24 and the lower horizontal bar 44 are in the same plane. Since the suspension line 31 is perpendicular to the horizontal plane, the plane in which the vertical bar 1, the upper horizontal bar 24 and the lower horizontal bar 44 are located is perpendicular to the horizontal plane, so the measured verticality is accurate.
