Description

Technical Field

[0001] This invention belongs to the field of building electromechanical installation technology, and in particular relates to an integrated device for positioning and measuring comprehensive supports and hangers, as well as a construction method thereon. Background Technology

[0002] In modern large-scale and complex public buildings, such as large commercial complexes, hospitals, data centers, industrial plants, and rail transit hubs, electromechanical pipeline systems (including ventilation and air conditioning, water supply and drainage, fire protection, power, and low-voltage intelligent systems) are like the "blood and nerves" of the building, with increasingly large scale and intricate layouts. Current technologies typically use integrated supports and hangers to provide unified and intensive support and fixation for these pipelines. The crossarms of the hangers or supports, as the foundation directly supporting the pipelines, require precise elevation positioning and levelness, which are crucial factors in ensuring the quality of pipeline installation and directly affect the safety and usability of the pipelines. Therefore, it is essential to ensure the accuracy of their installation. Currently, the positioning of crossarms is mainly done in steps: first, an elevation instrument is used for elevation positioning, and then a level is used for leveling. While this method can control installation accuracy, the need for multiple precise measurements and adjustments makes the entire process cumbersome and inefficient. Furthermore, the combined use of multiple tools increases the operational difficulty and can easily lead to the accumulation of errors, affecting overall installation accuracy and efficiency. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides an integrated support and hanger positioning and measurement device and construction method, which can simultaneously complete the elevation positioning and level adjustment of the crossarm, improve construction efficiency, and ensure the accuracy of crossarm positioning and level.

[0004] The technical solution adopted in this invention is:

[0005] An integrated support and hanger positioning and measurement device includes a longitudinal telescopic mechanism, a transverse telescopic mechanism, and a level. The longitudinal telescopic mechanism is detachably connected to a building structure and includes several longitudinal telescopic sections, each including a fixed section connected end-to-end and several longitudinal movable sections, and is marked with a length. The transverse telescopic mechanism is configured to correspond one-to-one with the longitudinal movable sections and is hinged to them. The level is rotatably connected to the other end of the transverse telescopic mechanism away from the longitudinal movable sections. The transverse telescopic mechanism is provided with a first strip-shaped bubble level, and the level is provided with a second strip-shaped bubble level.

[0006] Furthermore, one end of the fixed section is provided with a connecting plate for detachably connecting to the top plate of the structure or the top plate.

[0007] Furthermore, a first pin is provided on one side of the longitudinal movable section, the first pin being arranged perpendicular to the axial direction of the longitudinal movable section, and the lateral telescopic mechanism is connected to the first pin.

[0008] Furthermore, one end of the lateral telescopic mechanism is rotatably connected to a second pin, which is arranged along the axial direction of the lateral telescopic mechanism; the level includes a first end face and a second end face, the first end face being perpendicularly connected to the second pin, and the second end face being perpendicular to the first end face.

[0009] Furthermore, the level also includes a third end face and a fourth end face, the third end face being disposed opposite to the second end face, the fourth end face being disposed opposite to the first end face, and the second bar-shaped spirit level being disposed on the fourth end face.

[0010] Furthermore, the adjacent longitudinal expansion joints are nested together, and the outer longitudinal expansion joint is provided with an adjusting bolt to abut against the inner longitudinal movable joint.

[0011] Furthermore, the lateral telescopic mechanism includes a plurality of lateral telescopic sections, which are nested and connected to each other. The outer lateral telescopic section is provided with the adjusting bolt and is pressed against the inner lateral telescopic section by the adjusting bolt.

[0012] Furthermore, there are two first strip-shaped spirit levels, which are respectively disposed on both sides of the transverse expansion joint connected to the longitudinal movable section.

[0013] A construction method integrating the positioning and measurement of integrated supports and hangers, employing the integrated construction device for positioning and measurement of integrated supports and hangers as described above, includes the following steps:

[0014] Install hangers on the top slab of the structure or install supports on the bottom slab of the structure, and correct the verticality of the hangers or supports;

[0015] Install the fixing section and correct its verticality;

[0016] Install the first longitudinal movable section onto the fixed section to initially position the first layer crossbeam, pull out the transverse expansion joint, and use the first layer crossbeam to support the level.

[0017] Adjust the levelness of the first-layer crossarm and temporarily fix the first-layer crossarm;

[0018] Repeat the installation method of the first longitudinal movable section and the first layer crossarm, and install all longitudinal movable sections and temporarily fix all crossarms in sequence;

[0019] Verify all first and second bar spirit levels, dismantle the integrated support and hanger positioning and measurement construction device, and finally install all the crossarms.

[0020] Furthermore, adjusting the levelness of the first-layer crossarm includes: fine-tuning the inclination of the first-layer crossarm, observing the first and second bar spirit levels, and determining that the first-layer crossarm is in a horizontal state when both are centered.

[0021] The advantages and positive effects of this invention are:

[0022] (1) This invention integrates elevation measurement and level control into one unit, replacing the traditional serial and step-by-step operation mode of "measuring the elevation first and then finding the level". Construction personnel can simultaneously complete the elevation positioning and level adjustment of the crossbeam in one installation action, avoiding repeated tool switching and multiple adjustments, thereby significantly shortening the installation time and improving construction efficiency.

[0023] (2) The elevation is set directly through the longitudinal expansion joint and length mark, and the horizontality of the crossarm is adjusted by the cooperation of the first and second strip level, so that the elevation benchmark and the horizontal reference are "from the same source", avoiding the error superposition problem caused by step-by-step operation in the traditional method, and ensuring the accuracy of the crossarm positioning and horizontality.

[0024] (3) The number of longitudinal movable sections and transverse expansion joints of the device can be flexibly set according to the needs, which can adapt to both integrated hangers and integrated supports, and has wide applicability.

[0025] (4) By setting up temporary fixing, verification and final installation processes in the installation method, it is ensured that all crossarms can be permanently kept in the calibrated and accurate position, forming a closed-loop quality control process, which effectively ensures the reliability and stability of the crossarms and is conducive to ensuring the installation quality of subsequent integrated pipelines.

[0033] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0034] This invention proposes an integrated device for positioning and measuring crossarms and hangers. This device is used to detect and level the horizontality of crossarms during the construction of integrated supports and hangers, ensuring rapid and accurate installation of the hangers. In existing technologies, during crossarm installation, workers first use tools such as levels and laser levelers to project or mark a baseline on the building structure. Then, relying on personal experience and visual observation, they use a measuring tape to initially adjust the crossarm to near this baseline. Subsequently, a level is used to separately detect and level the crossarm. This sequential, distributed operation mode of "measuring the baseline first, then finding the level" requires repeated tool switching and adjustments, severely limiting installation efficiency and leading to the accumulation of errors. This results in the final installed crossarm deviating from the design baseline and failing to meet high-precision leveling requirements. The integrated support and hanger positioning and measurement device proposed in this application integrates elevation measurement and level control, realizing "setting is the same source, adjustment is synchronous". This allows construction personnel to complete the elevation positioning and level correction of the crossarm in one installation action, thereby greatly improving the installation efficiency and accuracy of the integrated support and hanger.

[0035] like Figures 1 to 5As shown, this embodiment of the invention proposes an integrated support 17 and a hanging frame positioning and measurement device, including a longitudinal telescopic mechanism 3, a transverse telescopic mechanism, and a level 15; the longitudinal telescopic mechanism 3 is used to detachably connect to the building structure, including several longitudinal telescopic sections, each of which includes a fixed section 8 connected end to end in sequence and several longitudinal movable sections 10, and is provided with a length mark 14; the transverse telescopic mechanism is provided in a one-to-one correspondence with the longitudinal movable sections 10 and is hinged to the longitudinal movable sections 10; the level 15 is rotatably connected to the end of the transverse telescopic mechanism away from the longitudinal movable sections 10; the transverse telescopic mechanism is provided with a first strip-shaped bubble level 6, and the level 15 is provided with a second strip-shaped bubble level 9. The longitudinal telescopic mechanism 3 is only used during the installation of the integrated support 17 or the integrated hanger 2. It is removed after installation to allow for the reuse of the entire device. It is installed on the building structure where the integrated support 17 or the integrated hanger 2 is located, with the building structure as the height calculation benchmark. During use, the longitudinal telescopic mechanism 3 is adjusted to extend vertically. By controlling the connection length of the longitudinal movable section 10, the height of the transverse telescopic mechanism and the level 15 can be adjusted so that the connection between the transverse telescopic mechanism and the longitudinal movable section 10 matches the design elevation of the crossarm 24 of the integrated support 17 or the integrated hanger 2. The level 15 is used to directly contact the crossarm 24 of the integrated support 17 or the integrated hanger 2, serving as a reference for the height and level of the crossarm 24. By adjusting the level of the transverse telescopic mechanism and the level 15, the height and level of the level 15 can be precisely adjusted, thereby achieving precise control of the elevation and level of the crossarm 24, improving the positioning efficiency of the crossarm 24, and ensuring its installation quality.

[0036] Under normal circumstances, such as Figure 1 As shown, the hanger includes hanger rods 25 and crossbeams 24. The hanger rods 25 are vertically mounted on the top slab 1 of the structure, and the crossbeams 24 are positioned between two hanger rods 25 or between a hanger rod 25 and the wall 22; Figure 5 As shown, the support includes support rods 26 and crossbeams 24. Support rods 26 are vertically mounted on the structural base plate 18, and crossbeams 24 are positioned between two support rods 26 or between support rods 26 and the wall 22. The longitudinal telescopic mechanism 3 can be configured according to the installation position of the integrated support 17 or the integrated hanger 2. For example, when it is used for the installation of the integrated support 17, the longitudinal telescopic mechanism 3 is also mounted on the structural base plate 18; when it is used for the installation of the integrated hanger 2, the longitudinal telescopic mechanism 3 is also mounted on the structural top plate 1. As long as the distance between the longitudinal telescopic mechanism 3 and the integrated support 17 or the integrated hanger 2 meets the telescopic range requirements of the lateral telescopic mechanism, it is acceptable.

[0037] Furthermore, in the embodiments of this application, such as Figure 1As shown, one end of the fixed section 8 is provided with a connecting plate 5 for detachable connection to the structural top plate 1 or the top plate 18. Specifically, the connecting plate 5 is provided with several bolt holes, which can be fixed to the structural top plate 1 or the structural bottom plate 18 by expansion bolts 4, facilitating installation and disassembly; at the same time, by controlling the drilling depth of different expansion bolts 4, the inclination of the connecting plate 5 can be adjusted, thereby controlling the verticality of the longitudinal telescopic mechanism 3, ensuring that the longitudinal telescopic mechanism 3 can be adjusted to a vertical state every time it is used, providing a reliable basis for subsequent height adjustment of the crossbeam 24.

[0038] Furthermore, in this embodiment, a first pin 13 is provided on one side of the longitudinal movable section 10. The first pin 13 is arranged perpendicular to the axis of the longitudinal movable section 10, and the transverse telescopic mechanism is connected to the first pin 13. When the longitudinal movable section 10 is arranged vertically, the first pin 13 is arranged horizontally. Therefore, when the transverse telescopic mechanism is horizontal, the height of the transverse telescopic mechanism and the level 15 can be determined by the height of the first pin 13, thereby determining the height of the crossarm 24. Because by aligning the height of the first pin 13 with the design elevation of the crossarm 24, the height of the crossarm 24 can be controlled to meet the design elevation requirements.

[0039] Furthermore, in this embodiment, a second pin 16 is rotatably connected to one end of the lateral telescopic mechanism, and the second pin 16 is arranged along the axial direction of the lateral telescopic mechanism; the level 15 includes a first end face and a second end face, the first end face being perpendicularly connected to the second pin 16; the second end face is perpendicular to the first end face. In use, the crossarm 24 is placed at the bottom of the first end face, and the two form surface contact. By adjusting the height of the crossarm 24, the lateral telescopic mechanism can be rotated around the first pin 13 until the lateral telescopic mechanism is in a horizontal state, at which point the second pin 16 is also in a horizontal state; by adjusting the angle of the crossarm 24, the level 15 can be rotated around the second pin 16 until the second end face is horizontal, at which point it can be determined that the crossarm 24 is also in a horizontal state. The above technical solution enables the elevation benchmark and the horizontal reference to be "from the same source", realizing the synchronous adjustment of the height and level of the crossarm 24. It eliminates the need to switch between measuring tools such as level, laser line projector, and tape measure, reduces the operation difficulty for construction personnel, improves the positioning and adjustment efficiency of the crossarm 24, avoids the error accumulation problem caused by step-by-step operation in the traditional method, and ensures the accuracy of the elevation and level of the crossarm 24.

[0040] Furthermore, in this embodiment, the level 15 also includes a third end face and a fourth end face. The third end face is positioned opposite to the second end face, and the fourth end face is positioned opposite to the first end face. The second strip-shaped spirit level 9 is positioned on the fourth end face. It is understood that the device connected to the top plate 1 and the device connected to the bottom plate 18 have opposite orientations. By setting the second and third end faces, both can be used to contact the crossbeam 24 in different usage scenarios, enabling the positioning and adjustment of the height and level of the crossbeam 24, making the device more flexible in use. Simultaneously, in both usage scenarios, the fourth end face is located on the relatively outer side of the device. Positioning the second strip-shaped spirit level 9 on the fourth end face makes it easier for construction personnel to observe.

[0041] In the above embodiment, the length direction of the second strip-shaped level 9 is the same as the length direction of the level ruler 15. When the transverse telescopic mechanism is horizontal and the bubble of the second strip-shaped level 9 is located in the middle, it can be determined that the second end face and the third end face are in a horizontal state, that is, the crossarm 24 is in a horizontal state.

[0042] Furthermore, the aforementioned longitudinal telescopic mechanism 3 can adopt a sleeve structure, a spiral structure, or an electric telescopic rod, etc., without limitation, as long as it can achieve length adjustment; preferably, in the embodiment of this application, adjacent longitudinal telescopic sections are nested and connected, and the longitudinal telescopic section located on the outer side is provided with an adjusting bolt 7 to abut against the longitudinal telescopic section located on the inner side. Through this setting, the longitudinal telescopic section can achieve a larger adjustment range and is easy to manufacture, assemble and adjust.

[0043] Specifically, the longitudinal expansion joint is a hollow tubular structure, and its inner diameter increases or decreases sequentially along the length of the longitudinal expansion mechanism 3. The inner and outer diameters of adjacent longitudinal expansion joints are matched and nested together. Preferably, one end of the longitudinal expansion joint is provided with several bolt holes evenly distributed around its circumference. An adjusting bolt 7 is threaded into the bolt hole. When another longitudinal expansion joint is inserted into the hollow structure, the longitudinal expansion joint can be locked by tightening the adjusting bolt 7 against its insertion end, thus realizing convenient adjustment of the connection length of adjacent longitudinal expansion joints.

[0044] In this embodiment, the number of longitudinal movable sections 10 corresponds to the number of crossbeams 24 to be installed, and can be flexibly set according to requirements. Each longitudinal movable section 10 is connected to a lateral telescopic mechanism. Preferably, the fixed section 8 has the largest inner diameter, one end of which is connected to the connecting plate 5, and the other end is provided with a bolt hole. A longitudinal movable section 10 is inserted into the fixed section 8 from the end with the bolt hole, which is defined as the first longitudinal movable section 19, and so on. The lateral telescopic mechanism is provided at the end of the longitudinal movable section 10 near the bolt hole.

[0045] Preferably, the cross-sectional shape of the longitudinal expansion joint is square or rectangular, so that adjacent longitudinal expansion joints can only move along their axial direction during assembly and adjustment, effectively avoiding relative deflection and achieving better stability. A bearing seat 12 is provided on one side end face of the longitudinal movable joint 10, and a first pin 13 is rotatably connected to the bearing seat 12. The transverse expansion mechanism is connected to the first pin 13, and its connecting end has a chamfered structure to ensure that the transverse expansion mechanism can rotate around the first pin 13. A length indicator 14 is provided on the other end face of the longitudinal movable joint 10 opposite to the bearing seat 12.

[0046] Furthermore, in this application, the structural form of the lateral telescopic mechanism can be the same as or different from that of the longitudinal telescopic mechanism 3, and no limitation is made here. In this embodiment, the structural form of the lateral telescopic mechanism is the same as that of the longitudinal telescopic mechanism, including a plurality of lateral telescopic sections 10, with adjacent lateral telescopic sections 10 nested and connected. The outer lateral telescopic section 10 is provided with an adjusting bolt 7, and the adjusting bolt 7 abuts against the inner lateral telescopic section 10. The specific structure and connection method of the lateral telescopic section 10 are the same as those of the longitudinal movable section 10, and will not be described in detail here.

[0047] In one specific embodiment, the transverse expansion joint 10 is provided with two sections. The transverse expansion joint 10 with a larger inner diameter is the first transverse expansion joint 20, one end of which is connected to the longitudinal movable joint 10, and the other end is provided with a bolt hole. The second transverse expansion joint 21 is inserted into the first longitudinal movable joint 19 from the end with the bolt hole, and the other end of the second transverse expansion joint 21 is rotatably connected to the second pin 16. The level 15 is connected to the second pin 16.

[0048] Similarly, the cross-sectional shape of the aforementioned transverse expansion joint is preferably square or rectangular.

[0049] Furthermore, there are two first-strip level bubbles 6, respectively disposed on both sides of the transverse expansion joint connected to the longitudinal movable section 10, used as a basis for judging the levelness of the transverse expansion joint in different usage scenarios. Specifically, the transverse expansion joint is the first transverse expansion joint 20, including two end faces disposed parallel to the first pin 13. The first-strip level bubbles 6 are respectively disposed on the two end faces and extend along the length direction of the transverse expansion joint. When the bubble of the first-strip level bubble 6 is located in the middle, it can be determined that the transverse expansion mechanism is in a horizontal state.

[0050] This invention also proposes an integrated construction method for the integrated support 17 and hanger positioning and measurement, which uses the aforementioned integrated construction device for the integrated support 17 and hanger positioning and measurement, and includes the following steps:

[0051] S1. Install the hanger 25 on the top plate 1 of the structure or install the support rod 26 on the bottom plate 18 of the structure, and correct the verticality of the hanger 25 or the support rod 26.

[0052] In one specific embodiment, the integrated support 17 and the integrated construction device for positioning and measuring the hanger are used to assist in the installation of the integrated hanger 2, such as... Figure 1 As shown, the integrated hanger 2 includes two hangers 25 and four crossbeams 24. The crossbeams 24 should be installed between the two hangers 25 according to the design elevation. In this step, the two hangers 25 are installed on the top plate 1 of the structure according to the designed coordinate position, and their verticality is corrected using a plumb line.

[0053] In another specific embodiment, the integrated support 17 and the integrated construction device for positioning and measuring the hanger are used to assist in the installation of the integrated support 17, such as... Figure 5 As shown, the integrated support 17 is intended to be installed near the wall 22, including a hanger 25 and four crossbeams 24. The crossbeams 24 should be installed between the support rod 26 and the wall 22 according to the design elevation. In this step, the support rod 26 is installed on the structural base plate 18 according to the designed coordinate position, and its verticality is corrected using a plumb line.

[0054] S2. Install the fixing section 8 and correct its verticality;

[0055] Specifically, based on the maximum length within the adjustment range of the lateral telescopic mechanism, measure and mark an appropriate distance starting from the center of the hanger 25 or support 26 to ensure that the level 15 can extend to the center of the hanger 25 or support 26; drill holes at the marked positions, and fix the connecting plate 5 at one end of the fixed section 8 to the top plate 1 of the structure with expansion bolts 4; and correct the verticality of the fixed section with expansion bolts 4 and a plumb line.

[0056] S3. Install the first longitudinal movable section 19 onto the fixed section 8, initially position the first layer crossbeam 24, remove the transverse expansion joint, and use the first layer crossbeam 24 to support the level 15.

[0057] Specifically, the first longitudinal movable section 19 is first inserted into the inside of the fixed section 8. The crossbeam 24 closest to the top plate 1 or bottom plate 18 of the structure is defined as the first-layer crossbeam 24. According to the design elevation of the first-layer crossbeam 24, the distance between the upper surface of the first-layer crossbeam 24 and the lower surface of the top plate 1 or the upper surface of the bottom plate 18 of the structure is converted. The depth of the first longitudinal movable section 19 inserted into the fixed section 8 is adjusted with reference to the length mark 14 so that the first pin 13 is located at the set height. It can be understood that the set height is higher than the design elevation of the upper surface of the first-layer crossbeam 24. The difference between the two can be calculated based on the size parameters of the level ruler 15 and the connection position.

[0058] Then, place the first-layer crossbeam 24 near the intended installation position, roughly flush with the transverse expansion joint; pull out the second transverse expansion joint 21, place the level 15 on the upper surface of the first-layer crossbeam 24, and lock the second transverse expansion joint 21 with the adjusting bolt 7.

[0059] S4. Adjust the level of the first-floor crossbeam 24 and temporarily fix the first-floor crossbeam 24.

[0060] Specifically, this includes fine-tuning the inclination of the first-layer crossbeam 24, observing the first strip-shaped level bubble 6 on the upper end face of the first transverse expansion joint 20 and the second strip-shaped level bubble 9 on the level ruler 15. When both are centered, it can be determined that the first-layer crossbeam 24 is in a horizontal state, and then the first-layer crossbeam 24 can be spot-welded to the hanger 25 or support 26 or the mounting seat 23 pre-set on the wall 22. If either bubble is not centered, the first-layer crossbeam 24 is adjusted repeatedly.

[0061] S5. Repeat the installation method of the first longitudinal movable section 19 and the first layer crossarm 24, and install all longitudinal movable sections 10 in sequence and temporarily fix all crossarms 24.

[0062] In this embodiment, the crossarm 24 has four layers. After the first layer of crossarm 24 is installed, the second layer of crossarm 24 is installed. The specific process is the same as the installation method of the first layer of crossarm 24, including installing the second longitudinal movable section to the first longitudinal movable section 19, initially positioning the second layer of crossarm 24, removing the transverse expansion joint connected to the second longitudinal movable section, using the second layer of crossarm 24 to support the corresponding level 15, adjusting the levelness of the second layer of crossarm 24, and temporarily fixing the second layer of crossarm 24. The positioning and installation of the third and fourth layers of crossarm 24 are carried out in this way, thus completing the installation of all longitudinal movable sections 10 and the temporary fixing of all crossarms 24.

[0063] S6. Verify all first bar level 6 and second bar level 9, dismantle the integrated support 17 and the integrated construction device for positioning and measuring the hanger, and carry out the final installation of all crossbeams 24.

[0064] In this embodiment, after all the longitudinal movable sections 10 and crossarms 24 are installed, check whether the first strip level 6 and the second strip level 9 corresponding to each layer are centered. If there is any offset, it needs to be readjusted. After confirming that all the bubbles are centered, the integrated support 17 and the integrated construction device for positioning and measuring the hanger can be removed. Then, all the crossarms 24 are fully welded to the hangers 25 or the support rods 26 or the mounting seats 23 pre-set on the wall 22.

[0065] The above technical solution achieves a closed-loop quality control system, ensuring that all crossarms 24 can be permanently maintained in their calibrated and precise positions, exhibiting good reliability and stability, which is beneficial to ensuring the installation quality of subsequent integrated pipelines.

[0066] The advantages and positive effects of this invention are:

[0067] (1) This invention integrates elevation measurement and level control into one unit, replacing the traditional serial and step-by-step operation mode of "measuring the elevation first and then finding the level". Construction personnel can simultaneously complete the elevation positioning and level adjustment of the crossbeam in one installation action, avoiding repeated tool switching and multiple adjustments, thereby significantly shortening the installation time and improving construction efficiency.

[0068] (2) The elevation is set directly through the longitudinal expansion joint and length mark, and the horizontality of the crossarm is adjusted by the cooperation of the first and second strip level, so that the elevation benchmark and the horizontal reference are "from the same source", avoiding the error superposition problem caused by step-by-step operation in the traditional method, and ensuring the accuracy of the crossarm height and horizontality.

[0069] (3) The number of longitudinal movable sections and transverse expansion joints of the device can be flexibly set according to the needs, which can adapt to both integrated hangers and integrated supports, and has wide applicability.

[0070] (4) By setting up temporary fixing, verification and final installation processes in the installation method, it is ensured that all crossarms can be permanently kept in the calibrated and accurate position, forming a closed-loop quality control process, which effectively ensures the reliability and stability of the crossarms and is conducive to ensuring the installation quality of subsequent integrated pipelines.

[0071] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
