Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of assembled column-beam connection structures, in particular to a dry connection structure for assembled columns and beams. Background Technique
[0002] At present, dry connection refers to a connection method in precast concrete structures that combines precast components and filling materials and connects the components together through friction, lapping force or locking force. Its characteristic is that wet concrete is not required during the connection process, so it is named "dry".
[0003] At present, a large amount of welding is required for the connection of assembled columns and beams. Welding itself not only requires welders with very rich experience, but also wastes a lot of time because there are many welding points. This results in the installation of assembled columns and beams not being very fast, wasting a lot of construction time. Therefore, it is necessary to design a dry connection structure for assembled columns and beams that does not require welding. Content of the Utility Model
[0004] To solve the technical problem that additional welding is required during the installation of existing assembled columns and beams, the utility model provides a dry connection structure for assembled columns and beams.
[0005] The utility model is realized by the following technical solutions: A dry connection structure for assembled columns and beams includes a main column. First limiting components capable of rapid splicing and limiting are provided on four sides of the main column. Fixing components for fixing with the main column are provided on both sides of each cross beam. Second limiting components for limiting each other are provided between every two adjacent cross beams. Limiting grooves are provided on both sides at one end of each cross beam. Insertion grooves are provided on the main column. The first limiting component includes a first limiting strip fixedly installed on the inner wall of the top of the insertion groove and a second limiting strip fixedly installed on the inner wall of the bottom of the insertion groove. One sides of the first limiting strip and the second limiting strip extend into the corresponding limiting grooves.
[0006] Through the above technical solutions, the cross beams are quickly limited by using the first limiting component and the second limiting component, and the fixing component can quickly fix the cross beams.
[0007] As a further improvement of the above solution, the cross beam is in sliding fit with the first limiting component through the limiting groove.
[0008] Through the above technical solutions, the cross beam can be slidably installed with the main column.
[0009] As a further improvement of the above solution, the fixing component includes a fixing plate fixedly installed on one side of the cross beam and a limiting plate arranged on one side of the fixing plate and fixedly installed with the main column. The limiting plate is arranged in an "L" shape.
[0010] Through the above technical solution, the limiting plate will limit the position of the fixing plate, achieving an effect of preventing tilting.
[0011] As a further improvement of the above solution, a plurality of first bolts are provided on the limiting plate, and the fixing plate is fixedly fitted with the limiting plate and the main column through the plurality of first bolts.
[0012] Through the above technical solution, the first bolts can fix the fixing plate, and thus the cross beam will also be fixed.
[0013] As a further improvement of the above solution, the second limiting component includes a limiting plate arranged between two cross beams and a plurality of second bolts installed on the limiting plate. The limiting plate is arranged in an "L" shape, and the limiting plate is fixedly installed on two adjacent cross beams through the plurality of second bolts.
[0014] Through the above technical solution, the multiple cross beams are limited and fixed to prevent the cross beams from shifting.
[0015] As a further improvement of the above solution, a support plate is provided at the bottom of each cross beam. One end of each support plate is fixedly installed with a first support block in contact with the bottom of the adjacent cross beam, and the other end of each support plate is fixedly installed with a second support block in contact with one side of the main column. A plurality of third bolts are provided on each of the first support block and the second support block. Each first support block is fixedly installed with the adjacent cross beam through the plurality of third bolts, and each second support block is fixedly installed with the main column through the plurality of third bolts.
[0016] Through the above technical solution, the support plate will support the cross beam to prevent the cross beam from tilting due to excessive weight.
[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0018] By providing the first limiting component, the fixing component and the second limiting component, when installing the assembled column and beam, the first limiting component and the second limiting component can be used to quickly install the cross beam onto the main column, and then the fixing component is used to fix the position of the cross beam. Welding is not required throughout the process. Such a setting can not only quickly fix and install the assembled column and beam, but also avoid wasting time on welding during the installation of the assembled column and beam.

[0024] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.
[0025] Please refer to Figures 1 - 3 , A dry connection structure of an assembled column and beam in this embodiment includes a main column 1. Cross beams 2 are provided on four sides of the main column 1. A first limiting component capable of quickly splicing and limiting is provided at one end of each cross beam 2. Fixing components for fixing with the main column 1 are provided on both sides of each cross beam 2. A second limiting component for limiting each other is provided between every two adjacent cross beams 2. Limiting grooves are opened on both sides at one end of each cross beam 2. A plugging groove is opened on the main column 1. The first limiting component includes a first limiting strip 301 fixedly installed on the inner wall of the top of the plugging groove and a second limiting strip 302 fixedly installed on the inner wall of the bottom of the plugging groove. One side of the first limiting strip 301 and the second limiting strip 302 extends into the corresponding limiting groove. The cross beam 2 is in sliding fit with the first limiting component through the limiting groove. The first limiting component and the second limiting component are used to quickly limit the cross beam 2, and the fixing component can quickly fix the cross beam 2.
[0026] Refer to Figure 1 and Figure 2 , The fixing component includes a fixing plate 401 fixedly installed on one side of the cross beam 2 and a limiting plate 402 provided on one side of the fixing plate 401 and fixedly installed with the main column 1. The limiting plate 402 is arranged in an "L" shape. A plurality of first bolts 6 are provided on the limiting plate 402. The fixing plate 401 is fixedly matched with the limiting plate 402 and the main column 1 through the plurality of first bolts 6. The limiting plate 402 limits the position of the fixing plate 401 to achieve an anti-tilting effect. The first bolts 6 can fix the fixing plate 401, and thus the cross beam 2 will also be fixed.
[0027] Combined with Figure 1 and Figure 2 , the second limiting component includes a limiting plate 501 arranged between two cross beams 2 and a plurality of second bolts 502 installed on the limiting plate 501. The limiting plate 501 is arranged in an "L" shape and is fixedly installed on two adjacent cross beams 2 through a plurality of second bolts 502. The multiple cross beams 2 are limited and fixed to prevent the cross beams 2 from shifting.
[0028] Combined with Figure 1 and Figure 2 , a support plate 7 is provided at the bottom of each cross beam 2. One end of each support plate 7 is fixedly installed with a first support block 8 in contact with the bottom of the adjacent cross beam 2, and the other end of each support plate 7 is fixedly installed with a second support block 9 in contact with one side of the main column 1. A plurality of third bolts 10 are provided on each of the first support block 8 and the second support block 9. Each first support block 8 is fixedly installed on the adjacent cross beam 2 through a plurality of third bolts 10, and each second support block 9 is fixedly installed on the main column 1 through a plurality of third bolts 10. The support plate 7 supports the cross beam 2 to prevent the cross beam 2 from tilting due to excessive weight.
[0029] The implementation principle of a dry connection structure for an assembled column and beam in an embodiment of this application is as follows: When installing the assembled column and beam, insert the limiting groove of the cross beam 2 along the first limiting strip 301 and the second limiting strip 302 into the insertion groove of the main column 1. When inserting in this way, the fixing plate 401 on the cross beam 2 will also be inserted into the limiting plate 402. Then use the first bolt 6 to fix the fixing plate 401 to the limiting plate 402 and the main column 1. After all the fixing plates 401 are fixed, place the limiting plate 501 at the right angle of each two adjacent limiting plates 501, and then use the second bolt 502 to fix the limiting plate 501 to two adjacent cross beams 2. In this way, the multiple cross beams 2 are fixed together to prevent the cross beams 2 from moving. Finally, place each support plate 7 at the bottom of the cross beam 2 and use the third bolt 10 to fix the first support block 8 and the second support block 9. In this way, the installation of the assembled column and beam is completed. This setting can not only quickly fix and install the assembled column and beam, but also avoid wasting time on welding during the installation of the assembled column and beam.
