[0028] The embodiments of the present invention are described below in conjunction with the drawings. The described embodiments are only a part of the embodiments of the invention, rather than all the embodiments.

[0032] like Figures 1 to 3, a schematic diagram of an embodiment of a template installation verticality detection device of the present invention, comprising a first positioning component, which includes a first crossbar 1 and a hook 2 that can be hung on any steel pipe 9 outside the template 7, the hook 2 is connected to the first crossbar 1, in conventional construction, square wood 8 is installed outside the template 7 and reinforced by tying steel pipe 9 outside the square wood 8; a vertical bar component, which is vertically connected to the first crossbar 1, and the vertical bar component can be retracted to lift the hook 2 to a predetermined height and hang it on the steel pipe 9; a second positioning component, which includes a second crossbar 3 vertically connected to the vertical bar component, when the hook 2 is hung on the corresponding steel pipe 9, the second crossbar 3 can be fixed outside the template 7 to adjust the vertical bar component to be parallel to the template 7; a measuring component, which includes a hanging rope 4 connected to the first crossbar 1 and a hanging hammer 5 connected to the end of the hanging rope 4. In this embodiment, the second crossbar 3 can be inserted between adjacent steel pipes 9 and can be inserted in the interval corresponding to adjacent square wood 8 at the same time, and the second crossbar 3 can be fixed to the outer wall of the template 7.

[0033] The length of the second crossbar 3 needs to be fixed in advance according to the fixing position of the second crossbar 3 and the size of the construction materials before the verticality is detected. When the verticality detection is satisfied, the vertical bar component can be parallel to the template 7. In this embodiment, the distance from the intersection of the first crossbar 1 and the vertical bar component to the center of the hook 2 is a known distance. When the hook 2 is hung on the steel pipe 9 to detect the verticality of the template 7, the distance from the center of the hook 2 to the template 7 is the compensation distance. The compensation distance can be calculated based on the known size of the construction materials, that is, in this embodiment, the compensation distance is the sum of half the outer diameter of the steel pipe 9 and the thickness of the square wood 8. The sum of the known distance and the compensation distance is the reference distance a1. The distance from the end of the second crossbar 3 close to the template 7 to the vertical bar component is the adjustment distance b1, and the adjustment distance b1 is equal to the reference distance a1. When the hook 2 is hung on the corresponding steel pipe 9, the distance from the intersection of the pendulum 5 and the first crossbar 3 in the vertical direction to the vertical bar component is the standard distance a2, and the horizontal distance from the pendulum 5 to the vertical bar component is the detection distance b2. The difference between the detection distance b2 and the standard distance a2 is used to detect the verticality of the template 7. In other embodiments, the second crossbar 3 can also be used to abut against the square wood 8. When the second crossbar 3 abuts against the square wood 8 to fix it, the compensation distance is the distance from the center of the steel pipe 9 to the square wood 8, which is usually half of the outer diameter of the steel pipe 9. Therefore, it can be known to those skilled in the art that the length of the second cross bar 3 is adjusted accordingly according to the fixing position of the second cross bar 3 and the size of the construction component, so that when detecting the verticality, the vertical bar component can be used as the reference line after the template 7 is translated, and only by measuring the detection distance b2, it can be determined whether the verticality of the template 7 installation meets the construction standard, which can reduce the measurement workload in the detection process, improve the detection efficiency, and prevent the detection quality from being affected by multiple measurement errors of personnel; in this embodiment, by inserting the second cross bar 3 in the interval of the square wood 8, the device of the present invention can be better fixed, the stability of the fixation can be improved, and construction accidents or injuries to personnel caused by the falling of the measuring device can be prevented; by fixing the hook 2 with the second cross bar 3, there is no need to add personnel for fixing the detection device, and one person can complete the detection work, reducing the labor cost of detection; the present invention can adjust the length of the vertical bar component to hang the hook 2 at a predetermined height, avoid repeated high-altitude operations by personnel, avoid hidden dangers of high-altitude operations, and improve detection safety.

[0034] It should be noted that the length of the second cross bar 3 needs to be fixed in advance according to the fixed position and the size of the construction materials before the verticality test.

[0035] On the other hand, the present invention also provides a method for using a template installation verticality detection device, comprising the following steps:

[0036] Adjust the length of the vertical rod component to lift the hook 2 to a predetermined height, hang the hook 2 on the corresponding steel pipe 9, insert the second cross bar 3 in the interval between the adjacent steel pipes 9 to fix the outer wall of the template 7, and then stabilize the invention device hung outside the template 7. When the second cross bar 3 is fixed outside the template 7, the vertical rod component is parallel to the template 7, and the vertical rod component can be used as a reference line after the template 7 is translated. The distance from the intersection of the pendulum 5 and the first cross bar 1 in the vertical direction to the vertical rod component is the standard distance a2, and the standard distance a2 can be determined after the invention device is installed. The horizontal distance from the pendulum 5 to the vertical rod component is the detection distance b2, and the difference between the detection distance b2 and the standard distance a2 is used to detect the verticality of the template 7 installation. When the difference meets the standard, the verticality of the template 7 installation meets the standard; when the difference does not meet the standard, the template 7 is adjusted and tested again until the verticality of the template 7 installation meets the standard.

[0037] The present invention can detect the verticality of the template 7 installation only by measuring the detection distance b2, which can reduce the measurement workload, improve the measurement efficiency, avoid personnel climbing for positioning through the adjustable vertical rod component, improve the safety of the detection process, and only perform one measurement, and determine whether the verticality of the template 7 installation meets the standard requirements based on the comparison of the measured value with the known data, thereby avoiding errors caused by multiple measurements by personnel, affecting the detection quality, and improving the detection accuracy.

[0038] In this embodiment, the vertical rod component includes a plurality of sleeves that are slidably connected to each other and nested step by step from the inside to the outside, and each lower sleeve is sleeved in the upper sleeve. The sleeve arranged in the inner layer is provided with at least one elastic clip 63, and the upper sleeve is provided with a positioning hole 64 that matches the elastic clip 63. In this embodiment, the number of sleeves is two, which are divided into an outer sleeve 61 and an inner sleeve 62, that is, the outer sleeve 61 is the upper sleeve of the inner sleeve 62, and the inner sleeve 62 is the lower sleeve of the outer sleeve 61. In this embodiment, a plurality of elastic clips 63 are evenly spaced and arranged on the inner sleeve 62 to facilitate accurate adjustment of the length of the vertical rod component, and the number of positioning holes 64 provided on the outer sleeve 61 is one to ensure flexibility when adjacent sleeves slide; in other embodiments, the number of positioning holes 64 can also be adjusted to multiple according to the stability of fixation. In this embodiment, the elastic clamp 63 includes an arc-shaped spring piece and mounting pieces connected to both ends of the arc-shaped spring piece. The arc-shaped spring piece and the mounting pieces at both ends of the arc-shaped spring piece can be formed by bending an elastic metal plate. The inner sleeve 62 has a mounting hole at a predetermined position. The arc-shaped spring piece gradually protrudes outward from the mounting hole and is connected to the inside of the inner sleeve 62 through the mounting piece. The outer sleeve 61 has a positioning hole 64 adapted to the arc-shaped spring piece. When the length of the vertical rod component is adjusted, the corresponding arc-shaped spring piece can be stuck in the positioning hole 64; when the inner sleeve 62 and the outer sleeve 61 slide against each other to adjust the length of the vertical rod component, the arc-shaped spring piece can be pressed downward or the outer sleeve 61 can be moved to squeeze the arc-shaped spring piece downward, so that the arc-shaped spring piece stuck in the positioning hole 64 is deformed and compressed in the inner sleeve 62, thereby realizing the mutual sliding between the inner sleeve 62 and the outer sleeve 61.

[0039] In this embodiment, the innermost sleeve, i.e., the inner sleeve 62, is connected to the second cross bar 3, and the outermost sleeve, i.e., the outer sleeve 61, is connected to the first cross bar 1; in other embodiments, the inner sleeve 62 can be connected to the first cross bar 1, and the outer sleeve 61 can be connected to the second cross bar 3 according to usage habits.

[0040] In this embodiment, the measuring component and the hook 2 are respectively arranged on both sides of the vertical rod component for measuring operation. In other embodiments, they can also be arranged on the same side according to the construction environment and space requirements.

[0041] In other embodiments, an operating handrail or an anti-slip sleeve may be provided on the outside of the vertical rod component to better facilitate hand-held operation by personnel and improve the efficiency of high-altitude positioning.

[0042] The present invention does not require personnel to perform height-ascending operations, and one person can quickly and accurately complete the detection of the verticality of the template installation; it has the advantages of simple structure, low processing cost, high construction safety, high detection efficiency and detection quality, and can save labor costs.

[0043] Embodiment 2:

[0044] like Figures 4 to 5As shown, in this embodiment, the second cross bar 3 is retractable to adjust the length. The second cross bar 3 includes a plurality of connecting tubes 31 that are sleeved with each other. Each connecting tube 31 has at least one adjustment hole. Adjacent connecting tubes 31 are slidably sleeved and fixed in length by inserting a fixing assembly 32 through the corresponding adjustment holes. The fixing assembly 32 includes a fixing bolt and a fixing nut. The retractable structure of the second cross bar 3 can be flexibly selected based on the common technical knowledge of those skilled in the art. The structure with adjustable length of the second cross bar 3 can be applied to construction scenes with square timbers 8 and steel pipes 9 of different sizes, improves the reuse rate of the device, and facilitates promotion and application; the structure with adjustable length of the second cross bar 3 can also fix the second cross bar 3 to different positions such as the template 7 or the square timber 8 according to the use requirements, improves the flexibility of application, and is better suitable for different construction environments. It should be noted that the length of the second cross bar 3 needs to be fixed in advance before the verticality test according to the fixed position, construction material size, etc., to ensure that the adjustment distance b1 is equal to the reference distance a1. That is, during the verticality test, the vertical bar component can be used as the reference line after the template 7 is translated. Only the detection distance b2 needs to be measured to determine whether the installation verticality of the template 7 meets the standard requirements.

[0045] The second cross bar 3 and the vertical bar component can also be movably connected to move along the length direction of the vertical bar component parallel and / or perpendicular to the vertical bar component, thereby improving the flexibility of the device. By moving along the length direction of the vertical bar component, the function of adjusting the distance b1 can be realized; by moving along the length direction of the parallel vertical bar component, the distance between the first cross bar 1 and the second cross bar 3 can be adjusted, so that the second cross bar 3 can avoid obstacles to be fixed outside the template 7. If the length of the second cross bar 3 is fixed, it needs to be inserted in the interval of the adjacent square wood 8, but when the second cross bar 3 is just located at the square wood 8, the second cross bar 3 can be moved along the length direction of the parallel vertical bar component to insert the second cross bar 3 into the interval of any adjacent square wood 8, thereby improving the construction efficiency and the flexibility of the device, and facilitating promotion and application. In this embodiment, the second cross bar 3 can only move along the length direction of the vertical bar component, and its movement mode can be flexibly mastered based on the general technical knowledge of those skilled in the art. In this embodiment, the second cross bar 3 is connected to a sliding sleeve that is slidably sleeved outside the vertical bar component, and the sliding sleeve 33 is slidably sleeved at the bottom of the inner sleeve 62 and fixed by screwing in the fastening bolts.

[0046] In this embodiment, the second crossbar 3 is provided with a scale line for detection on the surface, the second crossbar 3 and the vertical bar component are arranged in a cross shape, the length of the second crossbar 3 along the vertical bar component close to the template 7 is adjustable, and the second crossbar 3 is provided with a scale line corresponding to the pendulum 5 along the vertical bar component away from the template 7. When the verticality of the template 7 is detected and the verticality meets the requirements, the pendulum 5 can point to the corresponding standard range on the scale line; when the verticality of the template 7 does not meet the requirements, the pendulum 5 is offset to the corresponding standard range on the scale line. This method can replace the measuring ruler to quickly detect the verticality, and can also avoid measurement errors caused by improper operation when the personnel manually measure the horizontal distance, thereby improving the measurement quality and measurement efficiency. In this embodiment, the scale line is set on the second crossbar 3 and the second crossbar 3 is located at the bottom of the vertical bar component, so that the personnel can measure quickly and at close range. When it is necessary to compare with the position set at a high place, the measurement is convenient and fast, and it is better applied to the construction needs of measuring the verticality with a high place.

[0047] In different embodiments, the length of the hanging rope 4 needs to be adapted to the length of the vertical rod component after adjustment. Hanging ropes of different lengths can be pre-ordered in advance and can be detachably installed with the first crossbar 1 according to needs. In this embodiment, the measuring component also includes a spool 41 rotatably connected to the vertical rod component and a spool positioning member 42 connected to the first crossbar 1 to set up the hanging rope 4. The end of the hanging rope 4 away from the hanging hammer 5 is wound around the spool 41. The use of the hanging rope 4 with adjustable length and the vertical rod component with adjustable length can be applied to the verticality detection of different template heights, with a wide measurement range and strong practicality. In this embodiment, the bottom of the inner sleeve 62 is vertically connected to the rotating rod, the spool 41 is rotatably sleeved outside the rotating rod, and the end of the rotating rod away from the inner sleeve 62 is vertically connected to the limit plate. The limit plate can be fixed to the outside of the spool 41 to prevent the spool 41 from slipping when rotating. A turning handle is set on the spool 41 for easy operation. When the length of the hanging rope 4 is adjusted, the turning handle can be fixed to the limit plate to fix the length of the hanging rope 4. The rope positioning member 42 can be a round rod or a roller, which can locate the installation route of the rope 4. In this embodiment, the rope positioning members 42 are multiple and evenly spaced on the first crossbar 1. The detection personnel can select all or part of the rope positioning members 42 to set up the rope 4 according to the needs and construction environment, so as to improve the detection flexibility and can be used for complex environment detection. In other embodiments, the first crossbar 1 can also increase the setting scale to facilitate the rapid determination of the standard distance a2. In this embodiment, the vertical rod component is provided with multiple limiting rings 43 that can be sleeved on the outside of the rope 4 to locate the installation route of the rope 4. In this embodiment, a limiting ring 43 is respectively provided on the inner sleeve 62 and the outer sleeve 61. The fixing method of the multiple limiting rings 43 and the rope 4 is simple, and the hidden danger of entanglement when the length of the rope 4 is adjusted can also be prevented. It can be better used with the vertical rod component with adjustable length to meet the verticality detection requirements of various height templates 7 and improve the adjustment and detection efficiency of personnel.

[0048] The working process of this example is as follows:

[0049] Preparation: According to the height of the template 7 to be measured, slide the outer sleeve 61 and the inner sleeve 62 to adjust the length of the vertical rod. When the length of the vertical rod is fixed, fix the corresponding elastic clamp 63 through the positioning hole 64 to fix the length of the vertical rod; adjust the length of the second crossbar 3 so that the adjustment distance b1 is equal to the control distance a1. Set the hanging rope on the corresponding hanging rope positioning member 42 according to the construction environment and determine the standard distance a2.

[0050] When the template 7 is installed and vertically inspected, the hook 2 is lifted to a predetermined height by the vertical rod component and hung on the steel pipe 9, and the second cross bar 3 is fixed by abutting the outside of the template 7. When the second cross bar 3 is affected by the installation position of the square wood 8 and cannot be fixed on the outside of the template 7, the second cross bar 3 can be moved along the length direction of the vertical rod component so that the second cross bar 3 can be inserted in the corresponding adjacent square wood 8 interval and abut the outside of the template 7. At this time, the vertical rod component can be used as the reference line after the template 7 is translated. Through the scale line set on the second cross bar 3, it is detected whether the horizontal distance from the hanging hammer 5 to the vertical rod component meets the standard, that is, whether the error range of the detection distance b2 and the standard distance a2 meets the standard, that is, whether the distances of the two ends of the hanging rope 4 set vertically under the influence of gravity from the template 7 meet the error standard, that is, whether the installation verticality of the template 7 meets the standard. When the error of the installation verticality of the template 7 exceeds the standard range, the template 7 is adjusted and inspected again until the error meets the standard range requirements.

[0051] After the test is completed, the measuring parts can be disassembled and the length of the vertical rod parts can be shrunk to reduce the space occupied during storage.

[0052] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
