Abstract
Description
Technical Field
[0001] The invention relates to a fully assembled concrete frame and prefabricated wall structure with dry connectors, belonging to the field of construction. Background Art
[0002] In order to achieve sustainable development, the traditional construction industry model should shift towards industrialized and prefabricated construction. Currently, for prefabricated buildings, the connection between the main frame and the wall has become an important research direction.
[0003] There are two main types of existing connection methods: the first is to extend steel bars from the concrete frame and concrete wall for overlap, reserve post-cast strips at the steel bar overlap positions, and pour concrete on site to complete the connection. This is a grouting connection method, i.e., wet connection. This approach has also exposed many problems after its application in recent years: for example, the construction and installation speed is slow, the on-site installation of steel bars in the core area of beams and columns is difficult, and the quality of sleeve grouting is difficult to ensure.
[0004] The second type is a pre-buried steel plate in a concrete wall. The protruding steel plate is welded to the steel frame or connected with bolts. This requires high welding strength, and gaps are easily generated between the wall and the frame. Cracks will appear in the external decorative layer, affecting the appearance. Therefore, this application proposes a fully assembled concrete frame and prefabricated wall structure with a dry connector. Summary of the invention

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions: According to one aspect of the present invention, a fully fabricated concrete frame with dry connectors is provided.
[0007] The fully assembled concrete frame with dry connectors comprises a concrete frame column, a concrete frame beam and a dry connector. The concrete frame beam is symmetrically arranged between the concrete frame columns, and an installation space is formed between the concrete frame column and the concrete frame beam. The dry connector is installed in the concrete frame column and the concrete frame beam in an inlaid manner. The dry connector comprises a setting cylinder, and a connecting piece connecting the concrete frame column and the concrete frame beam is arranged in the setting cylinder. A secondary connecting piece connecting the prefabricated wall panel is also arranged in the setting cylinder. The connecting piece comprises two rotating screws rotatably arranged in the setting cylinder. The rotating screws are symmetrically arranged. A threaded sleeve is threaded on the rotating screw. Inserted steel bars are evenly fixed on the threaded sleeve. The inserted steel bars penetrate the setting cylinder. A accommodating space is opened in the concrete frame column and the concrete frame beam. The inner walls of the accommodating space are fixed with symmetrically arranged inserted cylinder rods, and reinforcing steel bars are evenly distributed between the inner walls. The number of the inserted cylinder rods is equal to the number of the inserted steel bars and corresponds to each other. The inserted steel bars are respectively inserted into the corresponding inserted cylinder rods.
[0008] Furthermore, one end face of the setting cylinder is open, and a driving member is respectively provided on the rotating screw, and the driving member is a manual turntable. A traction steel bar that slides through the threaded sleeve is also provided in the accommodating space, and the other end of the rotating screw is provided with a bearing fixed on the inner wall of the setting cylinder.
[0009] Furthermore, the auxiliary connecting member includes an auxiliary rotating screw rotatably arranged inside the setting tube, and the auxiliary rotating screw is threadedly sleeved with an auxiliary threaded sleeve plate, and the auxiliary threaded sleeve plate is a long strip plate, and a through frame passing through the setting tube is evenly fixed on the auxiliary threaded sleeve plate.
[0010] Furthermore, the auxiliary rotating screw is provided with an auxiliary driving part, which is an auxiliary manual turntable. The setting tube is also provided with an auxiliary traction steel bar that slides through the threaded sleeve. The other end of the auxiliary rotating screw is sleeved with an auxiliary bearing fixed on the inner wall of the setting tube.
[0011] According to another aspect of the present invention, a prefabricated wall structure is provided, comprising a fully assembled concrete frame with dry connectors and prefabricated wall panels, the prefabricated wall panels comprising a rectangular frame with a hollow interior and embedded parts inside, the embedded parts comprising an embedded tube and an internal rotating part, the rotating part comprising an internal rotating disk, an integrated extension plate is fixedly provided on the outer side of the rotating disk, the extension plates are respectively driven and connected with extension rods, the extension rods pass through the embedded tube and the prefabricated wall panels, and the inner side surfaces of the prefabricated wall panels are provided with through openings.
[0012] Furthermore, a sliding groove is formed on the extension plate, and a fixed round rod is fixedly provided on each of the extension rods and passes into the corresponding sliding groove.
[0013] Furthermore, a secondary fixed round rod is fixedly provided at the center of the back side of the rotating disk, and the other end of the secondary fixed round rod is sleeved with a rotating cylinder fixed to the inner wall of the embedded cylinder.

[0016] Beneficial effects of the present invention: By making improvements on the concrete frame columns and concrete frame beams and adding new connection methods, that is, adding dry connectors, the grouting connection method can be avoided. The grouting connection is a wet connection, which has a slow installation speed on the one hand, and on the other hand, the use of grouting will inevitably bundle more steel bars, further increasing the difficulty of on-site installation.
[0017] A manually driven rotating screw is adopted, and the rotation of the rotating screw drives the threaded sleeve on it to move, so that the two threaded sleeves move relative to each other, and the threaded sleeve drives the inserted steel bar to move out of the setting tube and insert it into the tube rod, thereby realizing the connection between the inserted tube rod and the inserted steel bar, and completing the setting tube embedded installation inside the concrete frame column and the concrete frame beam to realize dry connection.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0023] See also Figure 1-4 The present invention provides a technical solution: a fully assembled concrete frame with a dry connector, comprising a concrete frame column 1, a concrete frame beam 2 and a dry connector, wherein the concrete frame beam 2 is symmetrically arranged between the concrete frame columns 1, and an installation space 3 is formed between the concrete frame column 1 and the concrete frame beam 2, wherein the dry connector is installed in an inlaid manner inside the concrete frame column 1 and the concrete frame beam 2, and wherein the dry connector comprises a setting tube 5, wherein a connecting piece connecting the concrete frame column 1 and the concrete frame beam 2 is arranged inside the setting tube 5, and an auxiliary connecting piece connecting the prefabricated wall panel 4 is also arranged inside the setting tube 5 The connecting member includes two rotating screws 6 rotatably arranged inside the setting tube 5, the rotating screws 6 are symmetrically arranged, and a threaded sleeve 7 is threadedly sleeved on the rotating screw 6. Inserted steel bars 8 are evenly fixed on the threaded sleeve 7. The inserted steel bars 8 penetrate the setting tube 5. A accommodating space 9 is opened in the concrete frame column 1 and the concrete frame beam 2. The inner wall of the accommodating space 9 is fixedly provided with symmetrically arranged inserted cylinder rods 10, and reinforcing steel bars 11 are evenly distributed between the inner walls. The number of the inserted cylinder rods 10 is equal to the number of the inserted steel bars 8 and corresponds to each other. The inserted steel bars 8 are respectively inserted into the corresponding inserted cylinder rods 10.
[0024] See also Figure 1-4 One end face of the setting tube 5 is open, and a driving member is respectively provided on the rotating screw 6, and the driving member is a manual turntable 12. A traction steel bar 13 that slides through the threaded sleeve 7 is also provided in the accommodating space 9, and the other end of the rotating screw 6 is sleeved with a bearing 14 fixed on the inner wall of the setting tube 5. The secondary connecting member includes a secondary rotating screw 15 rotatably set inside the setting tube 5, and a secondary threaded sleeve 16 is threadedly sleeved on the secondary rotating screw 15. The secondary threaded sleeve 16 is a long strip, and a through frame 17 that passes through the setting tube 5 is evenly fixed on the secondary threaded sleeve 16. The secondary rotating screw 15 is provided with a secondary driving member, and the secondary driving member is a secondary manual turntable 18. A secondary traction steel bar 19 that slides through the threaded sleeve 7 is also provided in the setting tube 5. The other end of the secondary rotating screw 15 is sleeved with a secondary bearing 20 fixed on the inner wall of the setting tube 5.
[0025] The prefabricated wall panel 4 is installed in the installation space 3, and the inserted steel bars 8 and the inserted tube rods 10 have been connected in advance, that is, the setting tube 5 is embedded in the concrete frame column 1 and the concrete frame beam 2. At this time, the staff can rotate the secondary rotating screw to drive the secondary threaded sleeve 16 to move on the secondary rotating screw 15, and finally the through-frame 17 connected to the secondary threaded sleeve 16 passes through the setting tube 5, and finally the through-frame 17 just corresponds to the through-port 27, and the through-frame 17 goes deep into the through-port 27, so as to realize the connection between the through-frame 17 and the prefabricated wall panel 4, and finally realize the connection between the prefabricated wall panel 4, the concrete frame column 1 and the concrete frame beam 2.
[0026] After the overall installation is completed, a receiving space 9 is opened in the concrete frame column 1 and the concrete frame beam 2, and the receiving space 9 is communicated with the outside world, and concrete or mortar is poured into the receiving space 9, and the concrete or mortar will also enter the interior along the opening at one end of the setting tube 5. The concrete or mortar that finally enters will fuse and harden with the designed internal steel bars, thereby enhancing the overall strength of the concrete frame column 1 and the concrete frame beam 2, and completing the mortar filling inside the receiving space 9. When filling the mortar, a wooden board with a size larger than that of the receiving space 9 is required. The wooden board blocks the opening of the receiving space 9, and is screwed into the wooden board, the concrete frame column 1, and the concrete frame beam 2 until the mortar poured into the receiving space 9 hardens, and then the screws and the wooden board are removed. Therefore, the internal components of the setting tube 5 cannot be seen on the overall surface of the concrete frame column 1 and the concrete frame beam 2, and only the concrete surface can be seen on the surface of the concrete frame column 1 and the concrete frame beam 2.
[0027] See also Figure 1 and Figure 5-8According to an embodiment of the present invention, a prefabricated wall structure is further provided, comprising a fully assembled concrete frame with a dry connector and a prefabricated wall panel 4, wherein the prefabricated wall panel 4 comprises a rectangular frame 21 with a hollow interior and an embedded part 22 inside, wherein the embedded part 22 comprises an embedded tube 23 and an internal rotating part, wherein the rotating part comprises an internal rotating disk 24, wherein an integrated extension plate 25 is fixedly provided on the outer side of the rotating disk 24, wherein the extension plate 25 is respectively driven and connected with an extension rod 26, wherein the extension rod 26 passes through the embedded tube 23 and the prefabricated wall panel 4, wherein the inner side surface of the prefabricated wall panel 4 is provided with a through opening 27, wherein the extension plate 25 is provided with a sliding groove 28, wherein the extension rod 26 is fixedly provided with a sliding groove 28 corresponding to the inner side of the sliding groove 28 A fixed round rod 29 is provided, and a secondary fixed round rod 30 is fixedly arranged at the back center of the rotating disk 24. The other end of the secondary fixed round rod 30 is sleeved with a rotating cylinder 31 fixed to the inner wall of the embedded cylinder 23. A connecting steel bar 32 is fixedly arranged on the outer wall of the embedded cylinder 23. A rotating rod 33 is fixedly arranged at the front center of the rotating disk 24. The rotating rod 33 passes through the embedded cylinder 23, and the through end of the rotating rod 33 is rotatably embedded in the wall surface of the prefabricated wall panel 4. A plum blossom hole 34 is provided on the through end face of the rotating rod 33. A wrapping cylinder 35 and a secondary wrapping cylinder 36 are also fixedly arranged on the outer wall of the embedded cylinder 23. The extending rod 26 is slidably inserted into the wrapping cylinder 35, and the rotating rod 33 is slidably inserted into the secondary wrapping cylinder 36.
[0028] The personnel can hold the drill by hand and insert the drill bit of the drill into the plum blossom hole 34, and rotate the rotating rod 33 to drive the rotation of the rotating disk 24. The rotation of the rotating disk 24 drives the extension plate 25 to rotate, and finally drives the fixed round rod 29 to move in the sliding groove 28, thereby realizing the movement of the extension rod 26. The extension rod 26 moves to pass through the embedded tube 23. A through hole needs to be opened in advance on the setting tube 5. The extension rod 26 can enter the setting tube 5 along the through hole. The concrete frame column 1, the concrete frame beam 2, the setting tube 5, and the prefabricated wall panel 4 all have their own components extending into the interior of their components, thereby realizing the final dry connection of the several. After the final dry connection is completed, mortar can be poured into the accommodating space 9, and finally the hardened connection between the mortar and the several is enhanced.
[0029] The manufacturing method of the prefabricated wall panel 4 is to first use concrete pouring to manufacture a rectangular frame 21. During the pouring, the wrapping tube 35 and the auxiliary wrapping tube 36 will also be poured and embedded on the rectangular frame 21. Protection is required to prevent mortar from entering the wrapping tube 35 and the auxiliary wrapping tube 36. After completion, the interior of the rectangular frame 21 is in a cavity shape, and one end face of the rectangular frame 21 is in an open shape, so that the embedded part 22 can be better placed in the rectangular frame 21, and then the steel bar 32 is welded to the outer wall of the embedded part 22. The rotating tube 31 is an existing bearing, and then mortar is poured into the rectangular frame 21 or The design of concrete, wrapping tube 35 and sub-wrapping tube 36 avoids the connection between the poured mortar and concrete and the protruding rod 26, which makes the protruding rod 26 unusable later. When the cast concrete is not completely hardened, a through hole 27 is opened until it hardens to manufacture a complete prefabricated wall panel 4 without affecting the movement of the protruding rod 26. The entire designed accommodating space 9 is subsequently combined with mortar pouring to ensure that the entire designed wall is more solid, and combined with steel bar pouring, the concrete frame column 1, concrete frame beam 2 and prefabricated wall panel 4 are more stably connected after installation, pouring and hardening.
[0030] In the specific work, by improving the concrete frame columns and concrete frame beams and adding a new connection method, that is, adding a dry connector, the grouting connection method is avoided. The grouting connection is a wet connection. On the one hand, the installation speed is slow. On the other hand, the grouting will inevitably bundle more steel bars, further increasing the difficulty of on-site installation. The screw rod 6 is manually driven to rotate. The rotation of the screw rod 6 drives the threaded sleeve 7 on it to move, so that the two threaded sleeves 7 move relative to each other, and the threaded sleeve 7 drives the inserted steel bar 8 to move out of the setting tube 5 and insert it into the insertion tube. The cylinder rod 10 is inserted into the cylinder rod 10, thereby realizing the connection between the inserted cylinder rod 10 and the inserted steel bar 8, completing the setting of the cylinder 5 and installing it in an embedded manner inside the concrete frame column 1 and the concrete frame beam 2 to realize a dry connection, and finally the prefabricated wall panel 4 is installed in the installation space 3, and the designed components are also used to realize dry installation, and the installation efficiency is fast, and finally the simple and fast installation of the integrated concrete frame column, concrete frame beam and prefabricated wall panel is realized, and the stability of the prefabricated wall panel installation is improved, and a good tensile effect is formed between the concrete frame column 1, the concrete frame beam 2 and the prefabricated wall panel 4, which can improve the tensile performance of the prefabricated wall panel. The prefabricated wall panel 4 is installed in the installation space 3, and the inserted steel bars 8 and the inserted tube rods 10 have been connected in advance, that is, the setting tube 5 is embedded in the concrete frame column 1 and the concrete frame beam 2. At this time, the staff can rotate the secondary rotating screw to drive the secondary threaded sleeve 16 to move on the secondary rotating screw 15, and finally the through-frame 17 connected to the secondary threaded sleeve 16 passes through the setting tube 5, and finally the through-frame 17 just corresponds to the through-port 27, and the through-frame 17 goes deep into the through-port 27, so as to realize the connection between the through-frame 17 and the prefabricated wall panel 4, and finally realize the connection between the prefabricated wall panel 4, the concrete frame column 1 and the concrete frame beam 2. After the overall installation is completed, a receiving space 9 is opened in the concrete frame column 1 and the concrete frame beam 2, and the receiving space 9 is communicated with the outside world, and concrete or mortar is poured into the receiving space 9, and the concrete or mortar will also enter the interior along the opening at one end of the setting tube 5. The concrete or mortar that finally enters will fuse and harden with the designed internal steel bars, thereby enhancing the overall strength of the concrete frame column 1 and the concrete frame beam 2, and completing the mortar filling inside the receiving space 9. When filling the mortar, a wooden board with a size larger than that of the receiving space 9 is required. The wooden board blocks the opening of the receiving space 9, and is screwed into the wooden board, the concrete frame column 1, and the concrete frame beam 2 until the mortar poured into the receiving space 9 hardens, and then the screws and the wooden board are removed. Therefore, the internal components of the setting tube 5 cannot be seen on the overall surface of the concrete frame column 1 and the concrete frame beam 2, and only the concrete surface can be seen on the surface of the concrete frame column 1 and the concrete frame beam 2.The personnel can hold the drill and insert the drill bit of the drill into the plum blossom hole 34, and rotate the rotating rod 33 to drive the rotation of the rotating disk 24. The rotation of the rotating disk 24 drives the extension plate 25 to rotate, and finally drives the fixed round rod 29 to move in the sliding groove 28, so as to realize the movement of the extension rod 26. The extension rod 26 moves through the embedded tube 23. The setting tube 5 needs to be provided with a through hole in advance. The extension rod 26 can enter the setting tube 5 along the through hole. The concrete frame column 1, the concrete frame beam 2, the setting tube 5, and the prefabricated wall panel 4 all have their own parts extending into the interior of their parts, so as to realize the final dry connection of the several. Only after the final dry connection is completed, can mortar be poured into the accommodation space 9, and finally the hardened connection between the mortar and the several is enhanced. The accommodation space 9 of the entire design is subsequently matched with the mortar pouring to ensure that the entire design wall is more solid, and matched with the steel bar pouring, so that the concrete frame column 1, the concrete frame beam 2 and the prefabricated wall panel 4 are more stably connected after installation, pouring and hardening.
[0031] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
