Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a method for constructing an arched support frame. Background Technology

[0002] When constructing reinforced concrete beam-slab structures or steel structure composite floor slabs using profiled steel sheets, camber control of the structural beams, slabs, and profiled steel sheets is required according to design and construction requirements. Typically, camber construction involves simulating the camber arc length between spans in a computer based on the beam-slab structure span and the camber design and construction requirements. Then, the vertical supports are arranged along the span direction on the computer. The distance from the support foundation surface to the intersection of the support and the camber arc length, minus the support height under non-camber conditions, represents the required camber height for that support at its current position.

[0003] In existing technology, a construction method for an arched support frame involves first erecting the uprights under non-arched conditions based on a computer-simulated upright layout diagram. Before erection, on-site measurement and layout work is required to determine the accurate positions of the uprights. The initial upright installation height is the support height under non-arched conditions. Then, based on the arched height simulated in the computer for different uprights, the final support height of the uprights on-site is adjusted. The required arched height for each upright is determined by adjusting the adjustable top support, thus finalizing the upright support height. During the upright installation process, manual adjustments by workers are required, and continuous manual measurement is needed to control the verticality of the uprights to ensure construction requirements are met.

[0004] The construction methods for the aforementioned technologies are extremely cumbersome and inconvenient, requiring a large amount of manual labor for measurement, inspection, and adjustment. This results in low efficiency and low precision, significantly reducing the work efficiency of erecting support frames, and urgently needs improvement. Summary of the Invention

[0005] To improve the ease of erecting support frames and increase overall construction efficiency, this application provides a method for arching support frames.

[0006] The arching construction method for support frames provided in this application adopts the following technical solution: A method for constructing an arched support frame includes the following steps: S1, fixed beam uprights, multiple beam uprights are vertically arranged at intervals, and beam top supports are raised and lowered on the top of the beam uprights. The beam top supports are equipped with a first driving component for controlling the height of the beam top supports. By adjusting the height of the beam top supports, the tops of multiple beam top supports are made to be on the same horizontal plane, and an arched support area is formed between two adjacent beam uprights. S2, install the signal transmitter and signal receiver, install the beam signal transmitter and beam signal receiver between two adjacent beam uprights respectively, measure the distance between the two beam uprights and set it as L, and erect the mid-span upright at the center position between the two beam uprights; S3, Install the mid-span support. Install the liftable mid-span support on the mid-span upright. The mid-span support is equipped with a second drive component for controlling the mid-span support. Adjust the height of the mid-span support according to the arch height required for construction. The height difference H between the top of the mid-span support and the top of the beam support is: H=L*(1‰~3‰). S4, Install the signal transmitter, and install the mid-span signal transmitter on the mid-span upright; S5, Install intermediate uprights. Several intermediate uprights are installed between the mid-span upright and the beam upright. The intermediate uprights are installed one by one in the direction away from the beam upright. An intermediate signal receiver for receiving the signal from the mid-span signal transmitter is installed on the intermediate upright. The distance between the mid-span upright and the intermediate upright is measured and set as K. An adjustable height intermediate support is set on the intermediate upright. A third drive component for adjusting the height of the intermediate support is set on the intermediate support. The height of the intermediate support is adjusted according to the arch height required for construction. The height difference N between the top of the intermediate support and the top of the beam support is N = (L - 2K) * (1‰ ~ 3‰). S6. Install the top plate by laying it on top of the beam top support, mid-span top support, and intermediate top support to complete the construction of the support frame.

[0007] By adopting the above technical solution, the positions of multiple beam uprights are first determined to form an arched support area for creating an arched structure. The height of the top is adjusted by the beam top support to ensure consistency. Then, the distance between two beam uprights is determined by the beam signal transmitter and receiver. The mid-span upright is placed between the two beam uprights, and the height of the mid-span top support is adjusted according to the required arch height. Then, with the mid-span signal transmitter and receiver, the intermediate uprights are installed sequentially. After installing one upright, the height of the intermediate top support is adjusted simultaneously, allowing for more precise control of the intermediate upright height. Finally, the top slab is laid, thus realizing the construction of the arched support frame. The beam top support, mid-span top support, and intermediate top support are respectively driven by the first, second, and third drive components, which allows for more convenient control of the arch height adjustment and improves the ease of construction for workers.

[0018] Optionally, a sunshade can be detachably connected to the side of the beam signal receiver that receives the signal.

[0019] By adopting the above technical solution, the signals emitted by the beam signal transmitter can be received better, reducing the impact of external environment on construction accuracy and improving the precision of support frame construction.

Connecting rods 4 connect the beam uprights 1, mid-span uprights 3, and intermediate uprights 2. The method includes the following steps: S1, fix the beam uprights 1, and set multiple beam uprights 1 vertically at intervals. The top of the beam uprights 1 is equipped with a beam support 6 that is raised and lowered. The beam support 6 is equipped with a first driving component 21 for controlling the height of the beam support 6. By adjusting the height of the beam support 6, the tops of multiple beam support 6 are made to be on the same horizontal plane, and an arched support area is formed between two adjacent beam uprights 1. The workers divide it into multiple arched support areas and then carry out construction step by step.

[0036] S2, install the signal transmitter and signal receiver, install the beam signal transmitter 5 and the beam signal receiver 12 between two adjacent beam uprights 1 respectively, measure the distance between the two beam uprights 1 and set it as L, locate the middle position between the two beam uprights 1 according to the measured distance L, and erect the mid-span upright 3 at the center position between the two beam uprights 1. S3, Install the mid-span support 10. The liftable mid-span support 10 is installed on the mid-span upright 3. The mid-span support 10 is equipped with a second drive component for controlling the mid-span support 10. The height of the mid-span support 10 is adjusted according to the arch height required for construction. The height difference H between the top of the mid-span support 10 and the top of the beam support 6 is: H=L*(1‰~3‰). S4, Install the signal transmitter, install the mid-span signal transmitter 9 on the mid-span upright 3; S5, Install intermediate uprights 2. Several intermediate uprights 2 are installed between the mid-span upright 3 and the beam upright 1.

A third drive component for adjusting the height of the intermediate top support 11 is set on the intermediate top support 11. The height of the intermediate top support 11 is adjusted according to the arch height required for construction. The height difference N between the top of the intermediate top support 11 and the top of the beam top support 6 is N = (L-2K)*(1‰~3‰): By installing the intermediate uprights 2 in sequence, multiple intermediate uprights 2 can be gradually and more accurately formed into an arched support frame.

[0037] S6, Install the top plate 8, and lay the top plate 8 on the top support 6, the mid-span support 10 and the intermediate support 11 to realize the construction of the support frame.

[0038] Reference Figure 3 and Figure 4The beam top support 6 includes a connector 61 that is inserted into the top of the beam upright 1. A screw 15 is inserted into the connector 61, and a rotating ring 18 is rotatably connected to the connector 61. The rotating ring 18 has a threaded hole 19 that is threaded to engage with the screw 15. The first driving component 21 is a first driving motor. A driving gear 20 is fixed on the first driving component 21, and a driven gear 17 is fixed on the outer wall of the rotating ring 18. The driving gear 20 meshes with the driven gear 17, thereby making it easier to drive the rotating ring 18 to rotate and improving the convenience of adjusting the beam top support 6. The intermediate top support 11 and the mid-span top support 10 have the same structure as the beam top support 6 and are subject to unified control to ensure the accuracy of the arch formation.

[0039] Reference Figure 3 and Figure 4 The connector 61 includes two hinged seats 62 that are hinged to each other. A clamping cavity 22 for holding the rotating ring 18 is formed between the two hinged seats 62. A locking member 16, which is a locking bolt, is fixed between the two hinged seats 62 to fix them. The locking bolt allows the two hinged seats 62 to be more firmly connected together. A support seat 14 is fixed to the top of the screw 15. The support seat 14 has a plug groove 13 for the top plate 8 to be plugged in. The support seat 14 and the plug groove 13 form a U-shaped support, which can fix the top plate 8 more stably.

[0040] Reference Figure 5 The beam signal transmitter 5 is fixed to a first fixing seat 24 on its side wall. A first bolt 26 is rotatably connected to the first fixing seat 24. A first clamp 25 is rotatably connected to the first fixing seat 24. A first slot is provided on the first clamp 25 to engage with the first bolt 26, thereby making it easier to fix the beam signal transmitter 5.

[0041] Reference Figure 5 and Figure 6 In this embodiment, the beam signal transmitter 5 can also be fixed in another way. A second clamp is detachably connected to the side wall of the beam signal transmitter 5. The second clamp consists of a second connecting block 30 and a second connecting strip 31. Multiple second snap-fit ​​grooves 35 are provided on the outer wall of the second connecting strip 31.

A second snap-fit ​​block 34 is fixed to the inner wall of the second connecting slot 33 to engage with the second snap-fit ​​groove 35. A second snap-fit ​​post 29 is integrally formed on the side of the second connecting block 30 near the beam signal transmitter 5. A second locking groove 32 is provided on the beam signal transmitter 5 to engage with the second snap-fit ​​post 29. This allows the beam signal transmitter 5 to be fixed more conveniently. The beam signal receiver 12, the mid-span signal transmitter 9, and the intermediate signal receiver 7 can all be fixed using the above two methods, improving construction efficiency and convenience.

[0042] Reference Figure 6 A sunshade 28 is detachably connected to the side of the beam signal receiver 12 that receives the signal. The side of the sunshade 28 near the beam signal receiver 12 has a dovetail groove 27 that is inserted and matched with the sunshade 28, so that the signal emitted by the beam signal transmitter 5 can be received more conveniently. The sunshade 28 is also installed on the intermediate signal receiver 7, thereby improving the positioning accuracy of the support frame.

[0043] The signal receiver and signal transmitter are infrared transmitters and infrared receivers. A level 23 is fixed on both the signal receiver and the signal transmitter. The level 23 adopts a level bubble observation plate, which can more accurately detect the verticality of the steel pipe and improve the stability and firmness of the support frame.

[0044] The advantage of the arching construction method of the support frame in this application embodiment is that: the signal transmitter emits a horizontal laser and projects it onto the signal receiver, which can measure the horizontal distance between the signal transmitter mounting pole and the signal receiver mounting pole, thereby improving the accuracy of the positioning of the steel pipe; By controlling the height of multiple top supports, the arch of the support frame can be adjusted more precisely, ensuring the overall accuracy of the support frame.

[0045] By using a drive unit to control the height of the top support, the height of the top plate 8 can be adjusted more conveniently, thereby making it easier to control the arch height and improving the convenience of construction for workers.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
