Description

Technical Field

[0001] The invention relates to the field of building design and construction, and in particular to a support-free assembled concrete frame structure and a matching support device. Background Art

[0002] In the field of construction, the proportion of prefabricated buildings is steadily increasing. When processing the prefabricated concrete components of these prefabricated concrete buildings, they generally need to be processed and formed in the factory in advance and then transported to the site for installation of the prefabricated components.

[0003] At present, in the process of installing these precast concrete components, it is generally necessary to set up supporting scaffolding to support the horizontal components. For some horizontal components, formwork needs to be laid when they are poured into the connection positions. On the basis of retaining all the construction processes of cast-in-place structure buildings, it is also necessary to add component lifting, sleeve pipe and other processes. At the same time, some prefabricated building tower crane models are larger than cast-in-place structure buildings, and the number of supporting scaffolding also needs to be increased to meet the actual construction needs.

[0004] In view of the relevant technical situation, the inventor believes that in the process of installing prefabricated components, it is usually necessary to set up a lot of supporting scaffolding, and some prefabricated components also require additional component lifting. The whole construction process is relatively complicated, time-consuming and labor-intensive, and it is easy to increase unnecessary construction costs and increase the overall construction period of the building. Further improvements are needed in this regard. Summary of the invention

[0005] The purpose of this application is to provide a support-free assembled concrete frame structure and a supporting device, which can save the use of excessive scaffolding, simplify the entire construction process, save time and labor, and thus effectively improve work efficiency.

[0006] The present application provides a support-free assembled concrete frame structure, which adopts the following technical solution:

[0007] A support-free assembled concrete frame structure comprises: precast columns; precast main beams erected between the precast columns; a limiting structure arranged on the top of the precast columns for limiting the precast main beams; a precast secondary beam assembled with the precast main beams via a connecting structure; a composite plate arranged on the precast main beams and the precast secondary beams; and a supporting device arranged on the precast main beams and the precast secondary beams for supporting the composite plate.

[0008] By adopting the above technical scheme, by changing the design structure of prefabricated components, utilizing the bearing capacity of prefabricated composite components themselves, and taking certain auxiliary devices, the effect of prefabricated components being free of support can be achieved, thereby reducing the investment in scaffolding during construction, reducing the entire installation construction process, and speeding up the construction of standard floors. At the same time, a cleaner operating environment is provided for the construction site, the cost of secondary cleaning is reduced, and conditions for interspersing construction of other processes are provided, thereby reducing the overall construction period of the building and effectively improving work efficiency.

[0009] The present application further provides that: a supporting corbel for supporting the prefabricated main beam is provided on the top of the prefabricated column, and additional steel bars are built-in between the supporting corbel and the prefabricated column.

[0010] By adopting the above technical scheme, the supporting corbels can bear the prefabricated main beam to improve the stability of the entire concrete frame structure, and the additional steel bars can fix the supporting corbels in the prefabricated columns to enhance the firmness of both. At the same time, the use of supporting corbels can also reduce the use of auxiliary supporting devices, simplify the process and improve work efficiency.

[0011] The present application further provides: the connection structure includes: a shear-resistant connecting plate which is arranged on the outside of the prefabricated main beam and at the end of the prefabricated secondary beam and has multiple mounting holes; and a main reinforcement connecting plate which is arranged on the outside of the prefabricated main beam perpendicular to the shear-resistant connecting plate and is used to connect to the steel bars at the bottom of the prefabricated secondary beam.

[0012] By adopting the above technical scheme, in the process of installing the prefabricated main beam and the prefabricated secondary beam, the shear connecting plates of the two can be installed together by screws or bolts, which can not only firmly install the two together, but also save time and effort. The main reinforcement connecting plate set can further increase the firmness of the installation of the prefabricated main beam and the prefabricated secondary beam on the basis of the shear connecting plate.

[0013] The present application further provides: the limiting structure includes: limiting blocks arranged on both sides of the top of the prefabricated column, and the inner top of the limiting block is provided with a guide surface for guiding the prefabricated main beam.

[0014] By adopting the above technical solution, the limit blocks set up can limit the prefabricated main beam from both sides, reduce the deviation of the prefabricated main beam, so as to improve the accuracy of the entire prefabricated main beam construction, and the guide surface set up can guide the prefabricated main beam to facilitate the installation of the prefabricated main beam.

[0015] The present application further arranges: the supporting device includes: a hydraulic device vertically installed on the prefabricated main beam and the prefabricated secondary beam; a rubber pad arranged at the bottom of the composite plate; a supporting rod rotatably connected to the rubber pad at one end and rotatably connected to the output end of the hydraulic device at the other end; the prefabricated main beam and the prefabricated secondary beam are provided with strip grooves for installing the hydraulic device along the length direction.

[0016] By adopting the above technical solution, the hydraulic device and the support rod cooperate with each other. When the hydraulic device is turned on, one end of the support rod can be driven to move upward, and the end of the support rod away from the hydraulic device will generate an upward component force, which can provide a certain supporting effect on the rubber pad to carry the prefabricated main beam.

[0017] The present application also provides a matching supporting device, including: a frame; a sliding frame slidably arranged on the frame in a vertical direction; a lifting component arranged on the frame for driving the sliding frame to rise and fall; a strip board installed on the sliding frame for supporting the prefabricated main beam; and a guide component arranged on both sides of the strip board for guiding the prefabricated main beam so that the prefabricated main beam is placed at a predetermined position between the limit blocks.

[0018] By adopting the above technical scheme, during the installation of the prefabricated main beam, the supporting device can be used. During use, the supporting device can play a certain guiding role on the prefabricated main beam, so that the prefabricated main beam can be quickly located between the limit blocks. At the same time, the provided strips can also play a certain auxiliary supporting role in the construction process of the prefabricated main beam, so that the prefabricated main beam can be accurately placed in the predetermined position.

[0019] The present application further provides: the guide assembly includes: a slide plate slidably arranged on the strip along the length direction of the strip; a guide plate hinged at one end on the slide plate; an adjustment assembly arranged on the slide plate for adjusting the rotation angle of the guide plate; and a first driving member arranged on the strip for driving the two slide plates to move closer to or away from each other.

[0020] By adopting the above technical solution, the first driving member can drive the slide plate to move on the slat when it is turned on. When the slide plate moves, it will drive the guide plates to move closer to or away from each other, so that the guide plates can guide the two sides of the prefabricated main beam, so that the prefabricated main beam is placed in the predetermined position of the prefabricated column. The adjustment component can adjust the angle of the guide plate according to actual conditions to increase the guiding effect of the guide plate.

[0021] The present application further provides: the adjustment component includes: a triangular block slidably arranged on the slide plate; an inclined block mounted on the back of the guide plate and adapted to the triangular block; and a second driving member mounted on the slide plate for driving the triangular block to slide.

[0022] By adopting the above technical solution, when the angle of the guide plate needs to be adjusted, the second driving member can be turned on to drive the triangular block to slide. During the sliding process, the triangular block will drive the guide plate to rotate through the set inclined block to rotate to the optimal guide angle. This structural design is ingenious and the effect is obvious.

[0023] The present application further arranges: extension plates are installed on both sides of the strip board in the length direction, and positioning components for positioning the prefabricated main beam are installed on the extension plates.

[0024] By adopting the above technical solution, during the installation of the prefabricated main beam, the arranged positioning assembly can play a certain positioning role on the prefabricated main beam, thereby further increasing the accuracy of the installation of the prefabricated main beam and improving the construction quality on the basis of the guide assembly.

[0025] The present application further provides: the positioning assembly includes: a strip groove opened on the extension plate; a movable seat symmetrically arranged in the strip groove for sliding; a positioning plate with one end hinged on the movable seat and the other end exposed from the extension plate and hinged to each other; and a compression spring arranged at the inner end of the strip groove for abutting the movable seat so that the movable seat contacts the inner wall of the corresponding strip groove end; and a positioning cavity for accommodating the positioning plate is arranged at the bottom of the prefabricated main beam.

[0026] By adopting the above technical solution, in the process of the prefabricated main beam gradually approaching the positioning assembly, the arranged positioning plate will interfere with the edge of the positioning cavity at the bottom of the prefabricated main beam, so that while the positioning plate rotates more, it will also drive the compression elasticity to be further compressed, and the compression spring can use its own elastic force to react to the moving seat, so that the positioning plate can further abut the edge of the positioning cavity, so as to play a certain positioning role on the prefabricated main beam.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] By setting the supporting bracket and the limit structure, the two cooperate with each other and can play a certain supporting role on the prefabricated main beam, thereby reducing the investment in scaffolding during the construction process, reducing the entire installation and construction process, and effectively improving work efficiency;

[0029] By setting up a matching support device and a guide component of the matching support device, the accuracy and stability of the prefabricated main beam construction process can be increased on the original basis, and the positioning component can cooperate with the guide component to further improve the accuracy of the prefabricated main beam construction process, thereby improving the construction quality of the entire concrete structure.

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] The present application embodiment discloses a support-free assembled concrete frame structure, such as Figure 1 and Figure 2 As shown, it includes: prefabricated columns 1, multiple groups of prefabricated columns 1 are arranged according to actual conditions, a prefabricated main beam 11 is erected between two prefabricated columns 1, and in order to reduce the horizontal sliding of the prefabricated main beam 11, limited position structures are arranged on both sides of the top of the prefabricated columns 1.

[0036] In this embodiment, since the concrete of the prefabricated components has a certain strength when they are transported to the construction site for installation, the prefabricated components have sufficient bearing capacity and rigidity. During factory processing, standardized molds can be used to produce components with specific shapes as needed. In order to reduce the investment in scaffolding and formwork, a supporting corbel 10 is provided at the top of the prefabricated column 1, and in order to enhance the firmness of the supporting corbel 10, additional steel bars are provided between the supporting corbel 10 and the prefabricated column 1 for connecting the two.

[0037] When installing the prefabricated main beam 11, the supporting corbel 10 can be used to support it to reduce the use of scaffolding and formwork. In this embodiment, the limiting structure includes: limiting blocks 16 arranged on both sides of the top of the prefabricated column 1. When the prefabricated main beam 11 is installed on the supporting corbel 10, the set limiting blocks 16 can limit the prefabricated main beam 11 from both sides to reduce its horizontal sliding. In addition, in order to facilitate the prefabricated main beam 11 to slide quickly into the predetermined position between the two limiting blocks 16, a guide surface for guiding the prefabricated main beam 11 is arranged on the top of the inner side of the limiting block 16.

[0038] In this embodiment, prefabricated secondary beams 12 are assembled between prefabricated main beams 11 through a connecting structure. The prefabricated secondary beams 12 and the prefabricated main beams 11 are perpendicular to each other, and composite plates 13 are laid on the prefabricated main beams 11 and the prefabricated secondary beams 12. In order to improve the stability of the entire composite plate 13, supporting devices are provided on the prefabricated main beams 11 and the prefabricated secondary beams 12, and the supporting devices are used to support the composite plate 13.

[0039] Among them, the connection structure includes: a shear connection plate 14 arranged at the middle position of the outer side of the prefabricated main beam 11 and the end of the prefabricated secondary beam 12, and a plurality of mounting holes are opened on the shear connection plate 14. At the same time, a main reinforcement connection plate 15 is fixed on the outer side of the prefabricated main beam 11 and below the shear connection plate 14, and the main reinforcement connection plate 15 and the shear connection plate 14 are perpendicular to each other.

[0040] When installing the prefabricated main beam 11 and the prefabricated secondary beam 12, it is only necessary to align the shear connection plate 14 on the outside of the prefabricated main beam 11 with the shear connection plate 14 at the end of the prefabricated secondary beam 12, and then use bolts to pass through the installation holes to connect the prefabricated main beam 11 and the prefabricated secondary beam 12 together. At the same time, the main reinforcement connection plate 15 can also be connected to the steel bars at the bottom of the prefabricated secondary beam 12 by welding. Through this solution, a firm connection between the prefabricated main beam 11 and the prefabricated secondary beam 12 can be achieved.

[0041] Among them, the supporting device includes: a hydraulic device 17 vertically installed on the prefabricated main beam 11 and the prefabricated secondary beam 12. The hydraulic device 17 can adopt a hydraulic cylinder or an oil pressure cylinder. A rubber pad 18 is fixed at the bottom of the composite plate 13, and a support rod 19 is rotatably connected to the bottom of the rubber pad 18. The end of the support rod 19 away from the rubber pad 18 is rotatably installed on the output end of the hydraulic device 17. In addition, in order to reduce the space occupied by the hydraulic device 17, strip grooves are provided on both sides of the length direction of the prefabricated main beam 11 and the prefabricated secondary beam 12. The hydraulic device 17 can be installed in the strip groove. It should be noted that the height of the strip groove is sufficient for the output end of the hydraulic device 17 to extend and retract a predetermined distance.

[0042] When the hydraulic device 17 is turned on to drive the output end to extend, the force is transmitted to the rubber pad 18 through the support rod 19 , so that the rubber pad 18 is subjected to an upward force component to support the composite plate 13 .

[0043] This embodiment also provides a supporting device to assist in the installation process of the prefabricated main beam 11, thereby improving the stability and accuracy of the entire construction process. Figure 3 As shown, it comprises: a frame 2, on which a sliding frame 21 is slidably arranged in a vertical direction, and a lifting assembly is arranged on the frame 2, and the lifting assembly is used to drive the sliding frame 21 to slide in the vertical direction.

[0044] In this embodiment, in order to better support the prefabricated main beam 11, a strip board 22 is installed on the top of the sliding frame 21. When in use, the length direction of the strip board 22 is perpendicular to the length direction of the prefabricated main beam 11. Guide components are arranged on both sides of the strip board 22. During the installation of the prefabricated main beam 11, the arranged guide components can guide the prefabricated main beam 11 so that the prefabricated main beam 11 can be quickly placed in a predetermined position between the two limit blocks 16.

[0045] In this embodiment, the guide assembly includes: a slide plate 3 slidably arranged on both sides of the strip 22, the sliding direction of the slide plate 3 is consistent with the length direction of the strip 22, and a guide plate 31 is hinged on the side where the slide plates 3 are close to each other. In order to adjust the angle of the guide plate 31 according to actual conditions, an adjustment assembly is arranged on the slide plate 3. At the same time, a first driving member is also arranged on the strip 22, and the first driving member is used to drive the two slide plates 3 to approach or move away from each other.

[0046] When the prefabricated main beam 11 moves toward the position of the prefabricated column 1, the bottom edge of the prefabricated main beam 11 will abut against the guide plate 31. At this time, the guide plate 31 can be dynamically rotated under the drive of the adjusting component. At the same time, the first driving member can also drive the two slides 3 to approach each other. The adjusting component and the first driving member cooperate with each other to guide the entire prefabricated main beam 11 so that the bottom of the prefabricated main beam 11 accurately falls to the position between the two limit blocks 16.

[0047] Among them, the adjustment component includes: a triangular block 32 slidably installed on the slide plate 3, the sliding direction of the triangular block 32 is consistent with the sliding direction of the slide plate 3, and a tilting block 33 is fixed on the side of the guide plate 31 that is away from each other, the tilting surface of the tilting block 33 is parallel to the tilting surface of the triangular block 32, and a second driving member is installed on the slide plate 3. When it is necessary to adjust the angle between the guide plate 31 and the slide plate 3, the second driving member can be used to drive the triangular block 32 to slide on the slide plate 3. When the triangular block 32 slides, it will drive the guide plate 31 to rotate through the tilting block 33 to achieve the purpose of adjusting the angle of the guide plate 31.

[0048] In order to further improve the accuracy and stability of the prefabricated main beam 11 during the installation process, in this embodiment, extension plates 23 are fixed on both sides of the length direction of the strip plate 22, and a positioning component is arranged on the extension plate 23. When the prefabricated main beam 11 approaches the prefabricated column 1, the arranged positioning component can position the prefabricated main beam 11.

[0049] In this embodiment, the positioning assembly includes: a strip groove opened on the extension plate 23, a symmetrical moving seat 34 is slidably arranged in the strip groove, a positioning plate 35 is hinged on the moving seat 34, the end of the positioning plate 35 away from the moving seat 34 is exposed from the extension plate 23, and the ends of the two positioning plates 35 away from the moving seat 34 are hinged to each other, and a compression spring 36 is also installed in the strip groove, the end of the compression spring 36 is fixedly connected to the corresponding moving seat 34, and the compression spring 36 is placed in the strip groove. In the natural state, the compression spring 36 will use its own elastic force to drive the two moving seats 34 to abut against the inner wall of the end corresponding to the strip groove. In addition, a symmetrical positioning cavity is opened at the bottom of the prefabricated main beam 11 along its length direction, and the inner wall of the positioning cavity is an arc surface.

[0050] When the two sides of the bottom of the precast main beam 11 abut against the guide plates 31, the edges of the positioning cavity at the bottom thereof will also abut against the positioning plates 35, thereby driving the two moving seats 34 in the strip grooves to approach each other. As the precast main beam 11 gradually approaches the top of the precast column 1, the compression spring 36 will use its own elastic force to drive the two moving seats 34 away from each other, so that the positioning plates 35 abut against the bottom edges of the positioning cavities, so as to play a certain corrective role for the precast main beam 11, so that the position of the precast main beam 11 can be adjusted along its length direction until the precast main beam 11 is placed in the predetermined position at the top of the precast column 1 to complete the installation. Then the lifting assembly can be opened to drive the entire strip plate 22 to descend, so as to release the auxiliary support for the precast main beam 11. By using this device, the entire precast main beam 11 can be effectively supported by auxiliary support, which can not only increase the accuracy of the installation of the precast main beam 11, but also increase the stability.

[0051] In the present embodiment, it should be noted that the first driving member, the second driving member and the lifting assembly can all adopt relatively common air cylinders or hydraulic cylinders, which will not be described in detail here.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
