Description

Technical Field

[0001] This invention belongs to the field of prefabricated building technology, and specifically relates to a prefabricated building frame for energy-saving buildings. Background Technology

[0002] Prefabricated construction is a type of building that uses factory prefabrication as its core. Some or all of the building components (such as beams, slabs, columns, and walls) are processed in a factory and then transported to the construction site for assembly using reliable connection methods. It overturns the traditional construction model of "on-site casting and wet construction" and is one of the core directions for the industrialization, greening, and energy-saving development of the building industry.

[0003] In existing prefabricated building frames, the upper column is lifted by a crane and positioned directly above the lower column. Ground workers then straighten the upper column and lower it so that the reinforcing bars can enter the connection holes of the bottom connecting frame of the upper column. The connecting frame is supported by a support component, and then the reinforcing bars are connected to the external connecting nuts to fix the connecting frame, thus completing the assembly.

[0004] However, during the installation process, when lowering the upper column, the uniform length of the reinforcing bars at the bottom makes it difficult to quickly determine which reinforcing bar is misaligned if a jam occurs. This requires viewing from below to identify the misaligned bar, which is laborious to do and also makes accurate judgment difficult due to the angled view. It requires observation from both the left and right sides, making it time-consuming to check one reinforcing bar for misalignment. This necessitates checking multiple reinforcing bars sequentially, resulting in a lengthy process.

[0005] Therefore, it is necessary to invent a prefabricated building frame for energy-efficient buildings to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a prefabricated building frame for energy-efficient buildings, thereby resolving the issues raised in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated building frame for energy-saving buildings, comprising: The upper columns are used to form the frame; A connecting bracket, located at the bottom of the upper column, is used for connection; Connecting holes are equidistantly arranged around the connecting frame; The lower column, installed on the ground, is used to form the frame; The No. 1 reinforcing bar is located at a corner of the lower column; The No. 2 reinforcing bars are arranged equidistantly around the lower column, and the lengths of the multiple No. 2 reinforcing bars are arranged in decreasing order. A support assembly is disposed on the first rib and the second rib to support the connecting frame.

[0008] Furthermore, the length of the first reinforcing bar is greater than the length of the second reinforcing bar, and the difference between the length of the first reinforcing bar and the length of the longest second reinforcing bar is the depth of the connecting hole.

[0009] Furthermore, the length difference between adjacent second reinforcing bars is the depth of the connecting hole.

[0010] Furthermore, the tops of both the first rib and the second rib are set as planes, and the top of the second rib is provided with an early warning positioning component. The early warning positioning component can provide an early warning and assist in quickly finding the position of the deviated second rib when the top of the second rib deviates from the connecting hole.

[0011] Furthermore, the early warning positioning component includes: An airbag is positioned above the second rib. A puncture component is disposed above the No. 2 rib and is used to connect the airbag to the No. 2 rib and to puncture the airbag.

[0012] Furthermore, the puncture component includes: The base plate is connected to the top of the second reinforcing bar; A top plate is disposed above the bottom plate, and the airbag is located between the bottom plate and the top plate; A piercing needle, attached to the bottom of the top plate, is used to puncture the airbag; A support assembly is used to support the top plate.

[0013] Furthermore, the lifting component includes: A sliding rod is equidistantly connected to the bottom of the top plate; A pressure plate is disposed at the bottom of the slide rod, and the bottom plate has a cavity that mates with the pressure plate. The pressure plate is slidably disposed in the cavity. A spring connects the bottom of the pressure plate to the bottom wall of the cavity.

[0014] Furthermore, the airbag is in an inflated state, and an air filling hole is provided on the outside of the airbag. A plunger is provided inside the air filling hole, and the distance between the bottom of the needle and the top of the airbag is 2 cm.

[0015] Furthermore, a magnet is connected to the bottom of the base plate, and the magnet is attracted and fixed to the top of the second rib. The base plate, magnet, and top plate are all circular plate-shaped components, and the diameter of the base plate, magnet, and top plate is the same as the top diameter of the second rib.

[0016] Furthermore, the support component includes: Nuts are threaded onto the outside of the first and second reinforcing bars; The support plate is slidably installed outside the first and second reinforcing bars, and is located above the nut.

[0017] The technical effects and advantages of this invention are as follows: 1. This invention allows for the quick positioning of misaligned No. 2 reinforcing bars by setting No. 2 bars with progressively decreasing lengths and observing the connection holes on the connecting frame below the upper column. The entire positioning process is time-saving and labor-saving, greatly improving construction efficiency. 2. The invention can alert workers to the deviation of the No. 2 reinforcing bar by setting an early warning positioning component, so that the lowering of the upper column can be stopped in time to avoid damage to the No. 2 reinforcing bar. It can also help to judge the approximate position of the deviated No. 2 reinforcing bar. In conjunction with observing the connecting hole, the positioning speed can be further improved.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides a prefabricated building frame for energy-efficient buildings, such as... Figures 1 to 5 As shown, it includes: upper column 1, connecting frame 2, connecting hole 3, lower column 4, first reinforcing bar 5, second reinforcing bar 6, and support assembly; The upper column 1 is used to form a frame. The connecting frame 2 is set at the bottom of the upper column 1 for connection. The connecting frame 2 is the same as the connecting frame in the existing precast concrete assembly frame. The connecting holes 3 are equidistantly arranged around the connecting frame 2. The lower column 4 is installed on the ground to form a frame. The first reinforcing bar 5 is set at a corner position of the lower column 4. Both the upper column 1 and the lower column 4 are concrete columns. The first reinforcing bar 5 is embedded in the lower column 4 and its top extends out of the lower column 4. The second reinforcing bar 6 is equidistantly arranged around the lower column 4. The lengths of the multiple second reinforcing bars 6 decrease in succession. The second reinforcing bars 6 are embedded in the lower column 4 and their tops extend out of the lower column 4. The support component is set on the first reinforcing bar 5 and the second reinforcing bar 6 to support the connecting frame 2.

[0021] In use, the upper column 1 is lifted by a crane and positioned directly above the lower column 4. With the help of ground workers, the upper column 1 is straightened and then lowered so that the first rib 5 enters the connecting hole 3. Then, multiple second ribs 6 enter the connecting hole 3 in sequence. The connecting frame 2 is supported by the support assembly. Then, the first rib 5 and the second ribs 6 are connected to the external connecting nuts to fix the connecting frame 2. The assembly is then completed. If some of the No. 2 ribs 6 are skewed, straighten the upper column 1 and lower it. Since the No. 1 rib 5 is the longest, it will enter the connecting hole 3 first. Then, the longest of the No. 2 ribs 6 will enter the connecting hole 3 first. If there is a jam at this time, it means that the longest No. 2 rib 6 is skewed and its top is in contact with the bottom of the connecting frame 2. At this time, it should be corrected and the upper column 1 should be lowered. Then, multiple No. 2 ribs 6 of different lengths will be inserted into the connecting holes 3 in sequence. When a jam occurs, you only need to look at the multiple connecting holes 3 above in sequence to see which connecting hole 3 is empty and no No. 2 rib 6 has been inserted. This will quickly determine which No. 2 rib 6 is skewed and allow you to quickly locate the skewed No. 2 rib 6. In the existing technology, when lowering the upper column 1, because the length of the lower steel bars is uniform, if a jam occurs, there is no steel bar inserted in the connection hole 3 of the connecting bracket 2. It is impossible to quickly determine which steel bar is misaligned. It is necessary to look from below to see which steel bar is misaligned. Looking up from below is tiring, and the angled view from below makes it difficult to judge accurately. It is necessary to observe from both left and right perspectives at the same time. Therefore, it takes a long time to observe whether a steel bar is misaligned. Subsequently, multiple steel bars need to be checked in sequence, which takes a long time. However, with the present invention, it is only necessary to observe from above to see whether there is a No. 2 steel bar 6 in the lower connection hole 3. The No. 2 steel bar 6 below the connection hole 3 without the No. 2 steel bar 6 is misaligned. It can quickly locate the misaligned No. 2 steel bar 6 and improve the inspection speed.

[0022] like Figure 1 and Figure 3As shown, the length of the first reinforcing bar 5 is greater than the length of the second reinforcing bar 6. The difference between the length of the first reinforcing bar 5 and the length of the longest second reinforcing bar 6 is the depth of the connecting hole 3. The length difference between adjacent second reinforcing bars 6 is the depth of the connecting hole 3.

[0023] This ensures that when jamming occurs, i.e. when the connecting frame 2 cannot descend normally, the unbiased second rib 6 can be located in the connecting hole 3 and can be observed.

[0024] like Figures 1 to 5 As shown, the tops of both No. 1 rib 5 and No. 2 rib 6 are set as planes. The top of No. 2 rib 6 is equipped with a warning positioning component. The warning positioning component can provide a warning and assist in quickly finding the position of the deviated No. 2 rib 6 when the top of No. 2 rib 6 deviates from the connecting hole 3.

[0025] When the second rib 6 deviates, the warning positioning component will emit an audible warning to alert the user. At this time, the descent of the upper column 1 will be stopped to avoid damaging the second rib 6. At the same time, the audible warning can help to quickly locate the approximate position of the deviated second rib 6. In conjunction with observing the connecting hole 3, the positioning speed can be further improved.

[0026] like Figures 3 to 5 As shown, the early warning positioning component includes: airbag 7 and puncture component; The airbag 7 is positioned above the second rib 6, and the puncture component is positioned above the second rib 6. It is used to connect the airbag 7 and the second rib 6 and to puncture the airbag 7.

[0027] When the second reinforcing bar 6 deviates, as the upper column 1 descends, the puncturing component punctures the airbag 7, causing a popping sound to alert the worker that the second reinforcing bar 6 has deviated, and the worker can determine the approximate location of the deviated second reinforcing bar 6 based on the sound.

[0028] like Figure 5 As shown, the puncture assembly includes: a base plate 8, a top plate 9, a puncture needle 13, and a support assembly; The base plate 8 is connected to the top of the second reinforcing bar 6, the top plate 9 is set above the base plate 8, the airbag 7 is located between the base plate 8 and the top plate 9, the piercing needle 13 is fixedly connected to the bottom of the top plate 9 and is used to puncture the airbag 7, and the lifting assembly is used to support the top plate 9.

[0029] The undisplaced No. 2 rib 6 and the top plate 9 above it can pass through the connecting hole 3 normally. When the upper column 1 descends, the displaced No. 2 rib 6 will cause the connecting frame 2 to come into contact with the top plate 9, which will squeeze the top plate 9 and cause it to descend, thus coordinating with the piercing needle 13 to puncture the airbag 7, causing the airbag 7 to make a popping sound.

[0030] like Figure 5 As shown, the lifting assembly includes: a slide bar 10, a pressure plate 11, and a spring 12; The slide rod 10 is fixedly connected to the bottom of the top plate 9 at equal intervals. The pressure plate 11 is fixedly installed at the bottom of the slide rod 10. The bottom plate 8 has a cavity that cooperates with the pressure plate 11. The pressure plate 11 is slidably installed in the cavity. The spring 12 connects the bottom of the pressure plate 11 to the bottom wall of the cavity.

[0031] The spring 12 supports the pressure plate 11, slide bar 10, and top plate 9, so that when the top plate 9 is not under pressure, the needle 13 does not come into contact with the airbag 7.

[0032] like Figure 5 As shown, the airbag 7 is in an inflated state. The airbag 7 has an air filling hole (not shown in the figure) on its outside and a plunger (not shown in the figure) inside the air filling hole. The distance between the bottom of the needle 13 and the top of the airbag 7 is 2 cm.

[0033] When the top plate 9 is squeezed by the connecting frame 2, it will bring down the slide rod 10 and the pressure plate 11, causing the compression spring 12 to deform. As the top plate 9 descends, it will bring down the piercing needle 13 to puncture the airbag 7.

[0034] like Figure 4 and Figure 5 As shown, a magnet 16 is connected to the bottom of the base plate 8. The magnet 16 is attracted and fixed to the top of the second rib 6. The base plate 8, the magnet 16, and the top plate 9 are all set as circular plate-shaped components. The diameter of the base plate 8, the magnet 16, and the top plate 9 is the same as the top diameter of the second rib 6.

[0035] The magnet 16 facilitates the connection between the base plate 8 and the top of the second rib 6. After the connection is completed, the magnet 16 can be separated from the second rib 6, allowing the early warning positioning component to be reused repeatedly.

[0036] like Figure 3 As shown, the support assembly includes: nut 14 and support plate 15; Nut 14 is threaded to the outside of No. 1 rib 5 and No. 2 rib 6, and support plate 15 is slidably installed on the outside of No. 1 rib 5 and No. 2 rib 6, and is located above nut 14.

[0037] After all the No. 2 reinforcing bars 6 are inserted into the connecting holes 3, continue to lower the upper column 1 so that the connecting frame 2 abuts against the support plate 15, thus completing the support for the connecting frame 2 and the upper column 1.

[0038] The portions of reinforcing bars 5 and 6 extending out of the lower column 4 are threaded.

[0039] Working principle: In use, the upper column 1 is lifted by a crane and positioned directly above the lower column 4. With the help of ground workers, the upper column 1 is straightened and then lowered so that the first rib 5 enters the connecting hole 3. Then, multiple second ribs 6 enter the connecting hole 3 in sequence. The connecting frame 2 is supported by the support component. Then, the first rib 5 and the second ribs 6 are connected to the external connecting nuts to fix the connecting frame 2. The assembly is then completed. If some of the No. 2 ribs 6 are skewed, straighten the upper column 1 and lower it. Since the No. 1 rib 5 is the longest, it will enter the connecting hole 3 first. Then, the longest of the No. 2 ribs 6 will enter the connecting hole 3 first. If there is a jam at this time, it means that the longest No. 2 rib 6 is skewed and its top is in contact with the bottom of the connecting frame 2. At this time, it should be corrected and the upper column 1 should be lowered. Then, multiple No. 2 ribs 6 of different lengths will be inserted into the connecting holes 3 in sequence. When a jam occurs, you only need to look at the multiple connecting holes 3 above in sequence to see which connecting hole 3 is empty and no No. 2 rib 6 has been inserted. This will quickly determine which No. 2 rib 6 is skewed and allow you to quickly locate the skewed No. 2 rib 6. When the second rib 6 is deviated, as the upper column 1 descends, the connecting frame 2 will come into contact with the top plate 9, causing the top plate 9 to be squeezed and descend. This, combined with the piercing needle 13, will puncture the airbag 7, causing the airbag 7 to emit a popping sound as a warning. At this time, the descent of the upper column 1 will be stopped to avoid damaging the second rib 6. At the same time, the sound emitted can help to quickly find the approximate position of the deviated second rib 6. In conjunction with observing the connecting hole 3, the positioning speed can be further improved.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
