Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a connecting structure for a transfer beam of a large-span prefabricated building and an installation method thereof. Background Technique

[0002] A large-span structure building consists of many reinforced concrete slabs connected into a wavy integral thin-shell folded plate roof structure. Due to the requirements of building functions, when there is a large space in the lower part and some vertical members in the upper part cannot be directly and continuously connected to the ground, a structural transfer layer should be set up. In the structural transfer layer, transfer structural members need to be arranged. The transfer structural members are structural members set up to complete the transformation of the structural form from the upper floor to the lower floor or the change of the structural layout from the upper floor to the lower floor. The horizontal transfer structure in the transfer layer includes transfer beams, and transfer beams are used when connecting to the lower vertical members through the horizontal transfer structure.

[0003] At present, for the connection of transfer beams, bolts are usually used for connection. For example, the patent document with the Chinese patent authorization announcement number: CN215594604U (the authorization announcement date is January 21, 2022) provides a bolt-connected prefabricated transfer beam. In this patent, a first connection part for accommodating a first connecting member is provided on the side of the wall foundation. The first connecting member includes a connecting plate and a bolt. The first connection part includes a groove for accommodating the connecting plate and a reserved bolt hole, and the bolt and the connecting plate are used to make a firm and reliable effective connection with the superstructure.

[0004] However, the connection of the transfer beam using bolts in the above patent document also has the following problems:

[0005] 1. Bolts are suitable for bearing transverse loads, and only in this case can they exert the fixing effect to the greatest extent. The connection between the main beam and the floor slab is a longitudinal connection, and a great deal of force is required to tighten the bolt connection even with the help of tools. Considering convenience and durability, bolt connection is not a good choice;

[0006] 2. The transfer beam needs to have high strength and high stability performance to carry various loads during use. The column support method included in the transfer beam is relatively single, mostly directly contacting the ground or the floor. Due to the large self-weight of the transfer beam, during construction, its huge self-weight and complexity will be borne by the columns under the transfer beam. If the support strength is small, a support warning may occur.

[0007] In view of the above problems with the bolt connection of the transfer beam, there is an urgent need for a connecting structure for a transfer beam of a large-span prefabricated building and its construction technology to solve the above problems. Summary of the Invention

[0008] 1. Problems to be Solved

[0009] The object of the present invention is to solve the problems that when using bolt connection for transfer beams in the prior art, the structural strength and stability are relatively poor, and the construction operation is inconvenient. A connection structure for transfer beams in large-span prefabricated buildings and its installation method are provided. The design of this transfer beam connection structure is simple, the installation is convenient, the support effect is good, and the structural stability is high, effectively solving the above deficiencies of the existing transfer beam connection structures.

[0010] 2. Technical solution

[0011] In order to solve the above problems, the technical solutions adopted by the present invention are as follows:

[0012] A connection structure for transfer beams in large-span prefabricated buildings of the present invention includes a main beam and a floor slab. The main beam and the floor slab jointly form a transfer beam, and also includes columns. The floor slab is arranged on the top of the main beam, and columns are fixedly installed at the bottom of the main beam. Among them:

[0013] A working cavity is processed at the connection between the main beam and the floor slab. An active block is arranged in the working cavity. Clamping blocks are movably installed on both sides of the active block. The clamping blocks are clamped in the through holes of the floor slab. A threaded block is threadedly connected to the center of the active block. The threaded block penetrates through the main beam and is threadedly connected to the threaded hole opened on the main beam. A first threaded cap is arranged at the end of the threaded block. When fixing, the first threaded cap is tightened against the threaded hole to achieve the fixed installation of the main beam and the floor slab.

[0014] Two mounting seats are detachably installed on the column along its length direction. A support plate is rotatably installed on the upper mounting seat through a fixed seat. The bottom of the support plate is fixedly connected to the ground, and the support plate is rotatably connected to the lower mounting seat through a linkage plate on the side close to the column. Through the settings of the mounting seat, the support plate and the linkage plate, the tilt angle of the support plate can be effectively adjusted to meet the support effect of the transfer beam in different occasions, and the practicability is better.

[0015] As a further improvement of the present invention, two working cavities are provided. An active block is arranged in each working cavity. Connection blocks are symmetrically arranged on both sides of the active block. Both sides of the connection blocks are connected to the active block through rotating plates. The tops of the two connection blocks are respectively fixedly connected to the clamping blocks, and the two connection blocks are both slidably installed on a round bar. The two ends of the round bar are fixedly connected to the inner side wall of the working cavity. Through the setting of the round bar, the horizontal movement of the connection blocks is realized, ensuring that the clamping blocks are smoothly clamped into the through holes of the floor slab to complete the installation of the main beam and the floor slab.

[0016] As a further improvement of the present invention, guide grooves are opened on both sides of the inner cavity of the working cavity. Guide blocks are slidably connected to the inner cavity of the guide grooves. The bottom of the guide blocks is fixedly connected to the active block. Through the setting of the guide grooves, a limiting effect on the active block is achieved, preventing the active block from rotating.

[0017] As a further improvement of the present invention, the four corners of the top of the main beam are fixedly connected with positioning plates, and the four corners of the bottom of the floor slab are provided with positioning grooves that engage with the positioning plates.

[0018] As a further improvement of the present invention, the mounting seat is sleeved on the surface of the column, and its opening is connected to the mounting plate. Four rotating rods are rotatably installed in the cavity at the opening of the mounting seat. The mounting plate is recessed inwardly corresponding to the position of the rotating rod and the rotating rod is placed in the groove. One end of the rotating rod is processed with an external thread, and a threaded cap 2 is connected to the external thread, and one side of the threaded cap 2 is in contact with the mounting plate.

[0019] As a further improvement of the present invention, a protrusion is fixedly connected to one side of the mounting seat, one side of the protrusion passes through one side of the mounting plate, and a placement groove adapted to the rotating rod is opened on one side of the mounting seat.

[0020] As a further improvement of the present invention, the number of the fixing seats is at least three, a support plate is rotatably connected in the inner cavity of the fixing seat, an ear seat 1 is fixedly connected to one side of the support plate, a linkage plate is rotatably connected to the inner cavity of the ear seat 1, and an ear seat 2 is rotatably connected to the side of the linkage plate away from the ear seat 1, and the ear seat 2 is fixedly connected to the mounting seat located at the bottom, which significantly improves the flexibility of the support plate during adjustment, and the inclination angle of the support plate can be adjusted according to actual needs to adapt to the usage requirements in different scenarios.

[0021] As a further improvement of the present invention, there are four fixing seats, which are respectively fixedly installed on the mounting seat located at the upper part of the vertical pole and the surface of the mounting plate. There are also four corresponding ear seats, which are respectively fixedly installed on the mounting seat located at the lower part of the vertical pole and the surface of the mounting plate.

[0022] As a further improvement of the present invention, a spherical groove is provided at the bottom of the support plate, a spherical block is movably connected to the inner cavity of the spherical groove, and the bottom of the spherical block is fixedly connected to the bottom plate.

[0023] The installation method of the above-mentioned transfer beam connection structure for large-span prefabricated buildings includes the following steps:

[0024] Step 1: Preliminary positioning of the transfer beam structure formed by corresponding splicing of the main beam and floor slab;

[0025] Step 2: After completing the preliminary positioning, adjust the position of the movable block, fit the block into the through hole of the floor slab, tighten the threaded cap to press against the threaded hole of the main beam, and complete the positioning and fixing of the main beam and the floor slab;

[0026] Step 3: Install the two mounting seats on the surface of the column, determine the inclination angle of the support plate, adjust the installation positions of the two mounting seats according to the actual situation, fix the mounting seats on the column, and then fix the support plate to the ground to achieve the support effect on the transfer beam.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] (1) For the transfer beam connection structure for large-span prefabricated buildings of the present invention, through the optimized design of the installation methods of the main beam and the floor slab, especially by setting a working cavity at the connection between the main beam and the floor slab and installing a movable block and a clamping block in the working cavity, the positioning and installation connection of the main beam and the floor slab are achieved. Compared with the conventional bolt connection, not only the structural stability of the transfer beam is significantly improved, but also the installation operation can be simplified, and the labor intensity of installation is greatly reduced. At the same time, in the present invention, the main beam is supported by setting columns, and through the design of the support components of the columns, the support effect and stability are improved.

[0029] (2) For the transfer beam connection structure for large-span prefabricated buildings of the present invention, the working cavity is designed as two, and each working cavity is provided with installation components, namely a movable block, a connecting block and a clamping block, so as to well position, fix and install the main beam and the floor slab.

[0030] (3) For the transfer beam connection structure for large-span prefabricated buildings of the present invention, positioning plates are fixedly connected to the four corners of the top of the main beam, and positioning grooves are opened at the four corners of the bottom of the floor slab and are engaged with the positioning plates. During installation, the preliminary positioning of the main beam and the floor slab can be achieved through the cooperation of the positioning plates and the positioning grooves. During the secondary positioning and fixing, relative movement will not occur, which is beneficial to ensuring the smooth implementation of the installation.

[0031] (4) For the installation method of the transfer beam connection structure for large-span prefabricated buildings of the present invention, during the actual use process, the movable block and the clamping block are used to fixedly install the main beam and the floor slab, avoiding the traditional bolt fixing installation method. This installation operation is convenient and can improve the stability between the main beam and the floor slab. Secondly, the support components are used to support the columns, and the positions of the support components are adjustable, so as to better provide a support effect for the columns. Finally, the support components are installed through the fixing components, which is also convenient for the later disassembly of the support components. The transfer beam structure of the present invention has the advantages of stable installation, convenient use and good support effect. Therefore, it has a good market prospect and is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Embodiment 1

[0044] A connecting structure for a transfer beam of a large-span prefabricated building in this embodiment includes a main beam 1 and a floor slab 2. The main beam 1 and the floor slab 2 are installed and connected together to form a transfer beam. The floor slab 2 is detachably installed on the top of the main beam 1, and a column 12 is fixedly installed at the bottom of the main beam 1 to provide stable support for the transfer beam, thereby improving the stability of the transfer beam structure.

[0045] Specifically, as Figures 1-3 shown, a working cavity 3 is processed at the connection between the main beam 1 and the floor slab 2. An active block 4 is arranged in the working cavity 3. A threaded block 9 is threadedly connected to the center of the active block 4. The bottom end of the threaded block 9 penetrates to the bottom of the main beam 1 and extends outside the main beam 1. At the same time, a threaded hole 10 adapted to the threaded block 9 is opened inside the main beam 1. The threaded hole 10 is communicated with the working cavity 3. A first threaded cap 11 is threadedly connected to the bottom surface of the threaded block 9. The first threaded cap 11 is located outside the main beam 1. When fixing the threaded block 9 after adjusting the position of the active block 4, rotate the first threaded cap 11 to move on the threaded block 9, so that the first threaded cap 11 abuts against the threaded hole 10 of the main beam 1 to complete the fixation.

[0046] The whole active block 4 is arranged in the working cavity 3 of the main beam 1. Two clamping blocks 7 are movably installed on both sides of it. The end of the clamping block 7 extends into the working cavity 3 of the floor slab 2 and is snap-fitted and fixed with the through hole 8 on the floor slab 2. Specifically, taking the orientation in Figure 2 as an example for illustration, for the active block 4 in this embodiment, connection blocks 6 are symmetrically arranged on the left and right sides of it, and two clamping blocks 7 are also provided. Each clamping block 7 is fixedly installed on the top of the connection block 6.

[0047] Two V-shaped rotating plates 5 are respectively provided on the front and rear sides of the movable block 4. One end of the two rotating plates 5 located on the front side of the movable block 4 is rotatably mounted on the surface of the movable block 4, and the other ends of the two rotating plates 5 are rotatably connected to the corresponding connecting blocks 6 at their ends. The two rotating plates 5 located on the rear side of the movable block 4 are also installed in the same manner. This arrangement ensures that the left and right sides of each connecting block 6 are movably connected to the movable block 4 through the rotating plates 5, improving installation accuracy and facilitating installation.

[0048] At the same time, in order to ensure the control of the movement of the card block 7 at the top of the connecting block 6 and facilitate stable operation so that the card block 7 can be smoothly and quickly inserted into the through hole 8, a round rod 25 is arranged in the working chamber 3 along the horizontal direction. The inner cavities of the two connecting blocks 6 are slidably connected with the round rod 25. Both ends of the round rod 25 are fixedly connected to the working chamber 3. Through the setting of the round rod 25, the connecting block 6 will slide on the surface of the round rod 25 when it moves, which plays a role in improving the activity stability of the connecting block 6, thereby ensuring that the card block 7 is accurately inserted into the through hole.

[0049] In addition, guide grooves 26 are provided on both sides of the inner cavity of the working chamber of the main beam 1. Guide blocks 27 are slidably connected to the inner cavity of the guide grooves 26. The bottom of the guide blocks 27 is fixedly connected to the movable block 4. Through the coordinated use of the guide grooves 26 and the guide blocks 27, when the movable block 4 moves, the guide blocks 27 are driven to slide in the inner cavity of the guide grooves 26, thereby guiding the movable block 4 and preventing it from rotating.

[0050] In addition, it is more optimized to fix the operating block 28 on the threaded block 9, and a plurality of anti-slip grooves are provided on the surface of the operating block 28. The setting of the operating block 28 facilitates the rotation of the threaded block 9, and the setting of the anti-slip grooves can increase the friction during rotation to avoid slipping.

[0051] During use, by turning the operating block 28, the threaded block 9 rotates within the threaded hole 10. As the threaded block 9 rotates, the movable block 4, connected to the threaded block 9, is constrained by the guide slot 26 and the guide block 27, forcing it to move upward or downward along the threaded block 9. As the movable block 4 moves upward or downward, the rotating plate 5 rotates, with the rotating plates 5 on the same side of the movable block 4 rotating in opposite directions, exhibiting a tendency to "close" or "disperse." Simultaneously, the connecting block 6, rotatably connected to the rotating plate 5, is constrained by the round rod 25 and moves along it, with the two connecting blocks 6 moving in opposite directions. When installing and securing the main beam 1 and floor slab 2, the threaded block 9 is rotated to move the movable block 4 upward. This upward movement of the movable block 4 causes the connecting blocks 6 on either side of it to move in opposite directions, causing the retaining blocks 7 to engage their respective through-holes in the floor slab 2. Then, the threaded cap 11 is rotated to tighten against the threaded hole 10 of the main beam 1, completing the securement.

[0052] In addition, as a further improvement of this embodiment, two working chambers 3 are provided. The structures in the two working chambers 3 are the same, and the two working chambers 3 are symmetrically arranged. By providing two working chambers 3 and an installation component, namely the movable block 4, the clamping block 7 and other connected components, the reliable connection between the main beam 1 and the floor slab 2 is effectively achieved, and the stability of the connection structure is significantly improved.

[0053] As a further design of this embodiment, as Figure 3 shown, positioning plates 23 are fixedly connected to the four corners of the top of the main beam 1, and positioning grooves 24 that are engaged with the positioning plates 23 are provided at the four corners of the bottom of the floor slab 2. In addition, in this embodiment, positioning grooves 24 can also be fixedly connected to the four corners of the top of the main beam 1, and positioning plates 23 are provided at the four corners of the bottom of the floor slab 2, and the positioning plates 23 are snap-fitted into the positioning grooves 24. Through the engagement of the positioning grooves 24 and the positioning plates 23, the preliminary positioning of the main beam 1 and the floor slab 2 can be achieved, which is convenient for the clamping block in the subsequent installation component to be inserted into the through hole 8, effectively improving the assembly efficiency, and the connection of the positioning grooves 24 and the positioning plates 23 also further improves the connection stability between the main beam 1 and the floor slab 2, thus ensuring the strength and bearing capacity of the transfer beam structure.

[0054] The transfer beam connection structure of the present invention further includes a support component, and the support component includes a column 12 and a support plate 19 installed on the column 12. Specifically, as Figure 1 and Figures 4-5 shown, two mounting seats 13 are detachably installed on the column 12 along its length direction. A support plate 19 is rotatably installed on the upper mounting seat 13 through a fixed seat 18. The bottom of the support plate 19 is fixedly connected to the ground, and one side of the support plate 19 close to the column 12 is rotatably connected to the lower mounting seat 13 through a linkage plate 21. Through this design, the tilting installation angle of the support plate 9 can be adjusted, and the included angle between the support plate 9 and the column 12 can be adjusted according to actual needs to meet the support requirements in different scenarios.

[0055] Embodiment 2

[0056] As Figure 1 and Figure 4As shown in the figure, a large-span prefabricated building modular roof structure in this embodiment has a basic structure similar to that of Embodiment 2, and its main difference lies in that: the mounting seat 13 is sleeved on the surface of the column 12, and an opening is provided on one side thereof. The opening of the mounting seat 13 is connected to the mounting plate 14 for installation. Specifically, four rotating rods 15 are rotatably installed in the cavity at the opening of the mounting seat 13, and a placement groove 33 adapted to the rotating rods 15 is provided on one side of the mounting seat 13. A groove 16 is recessed inwardly on the mounting plate 14 at a position corresponding to the rotating rod 15. The rotating rod 15 is placed in the groove 16. One end of the rotating rod 15 is processed with an external thread, and a second threaded cap 17 is connected to the external thread. One side of the second threaded cap 17 is in contact with the mounting plate 14. When fixing, after adjusting and determining the installation position of the mounting seat 13, the four rotating rods 15 are inserted into the groove 16, and the second threaded cap 17 is screwed to lock, realizing the fixed installation of the mounting seat 13 and the column 12.

[0057] As a further improvement of this embodiment, a convex block 29 is fixedly connected to one side of the mounting seat 13. One side of the convex block 29 penetrates to the other side of the mounting plate 14. When positioning the mounting seat 13, the convex block 29 is extended to one side of the mounting plate 14, thereby playing a role in positioning the mounting plate 14 and preventing the situation that the mounting plate 14 is inclined and affects the positioning effect.

[0058] In addition, more optimally, at least 3 fixing seats 18 are provided in this embodiment. A support plate 19 is rotatably connected in the inner cavity of the fixing seat 18. One side of the support plate 19 is fixedly connected to an ear seat one 20. A linkage plate 21 is rotatably connected in the inner cavity of the ear seat one 20. One side of the linkage plate 21 far from the ear seat one 20 is rotatably connected to an ear seat two 22. The ear seat two 22 is fixedly connected to the lower mounting seat 13. Designed in this way, by moving the mounting seat 13 up or down, through the setting of this connection structure, the angles of multiple support plates 9 can be adjusted simultaneously. The operation is convenient and fast, and the same connection structure setting can also ensure the consistency of the inclination angles of the support plates 9, effectively ensuring the support effect and enhancing the support strength of the transfer beam.

[0059] Furthermore, to further improve the stability of the support, 4 fixing seats 18 are provided, which are respectively fixedly installed on the surfaces of the mounting seat 13 and the mounting plate 14 located on the upper part of the vertical rod 12. 4 ear seats two 22 are also correspondingly provided, which are respectively fixedly installed on the surfaces of the mounting seat 13 and the mounting plate 14 located on the lower part of the vertical rod 12.

[0060] In addition, as Figure 5As shown in the figure, a spherical groove 30 is opened at the bottom of the support plate 19. A spherical block 31 is movably connected to the inner cavity of the spherical groove 30, and a bottom plate 32 is fixedly connected to the bottom of the spherical block 31. In this embodiment: through the cooperation of the spherical groove 30, the spherical block 31 and the bottom plate 32, after the support plate 19 is tilted and the bottom plate 32 contacts the ground, the bottom plate 32 will drive the spherical block 31 to move in the inner cavity of the spherical groove 30, thereby playing a role in keeping the bottom plate 32 always parallel to the ground.

[0061] The installation method of the conversion beam connection structure of the present invention includes the following steps:

[0062] Step 1: Perform preliminary positioning on the conversion beam structure formed by splicing the main beam 1 and the floor slab 2 correspondingly.

[0063] Specifically, place the main beam 1 at the bottom of the floor slab 2. At this time, the positioning plate 23 will be stuck into the inner cavity of the positioning groove 24, and this process positions the main beam 1 and the floor slab 2.

[0064] Step 2: After completing the preliminary positioning, adjust the position of the movable block 4, engage the clamping block 7 in the through hole 8 of the floor slab 2, and tighten the first threaded nut 11 to abut against the threaded hole 10 of the main beam 1 to complete the positioning and fixation of the main beam 1 and the floor slab 2.

[0065] Specifically, rotate the operating block 28. When the operating block 28 rotates, it drives the threaded block 9 to rotate. Since the threaded block 9 and the movable block 4 are rotationally connected, when the threaded block 9 rotates, it will drive the movable block 4 to move upward under the action of the threaded hole 10. When the movable block 4 moves upward, it drives the rotating plate 5 to rotate. When the rotating plate 5 rotates, it can drive the connecting block 6 to move to one side. The movement trajectories of the two connecting blocks 6 are opposite. The connecting block 6 drives the clamping block 7 to move to one side and extend to the outside of the through hole 8, which can play a role in connecting the main beam 1 and the floor slab 2, thereby improving the connection stability between the main beam 1 and the floor slab 2. Then, by rotating the first threaded nut 11, the first threaded nut 11 rotates upward on the surface of the threaded block 9. When the top of the first threaded nut 11 contacts the main beam 1, it plays a role in positioning the threaded block 9.

[0066] Step 3: Install two mounting seats 13 on the surface of the column 12, determine the inclination angle of the support plate 19, adjust the installation positions of the two mounting seats 13 according to the actual situation, fix the mounting seats 13 on the column 12, and then fix the support plate 19 to the ground to realize the support function for the conversion beam.

[0067] Specifically, the position of the mounting base 13 can be selected according to the actual situation. When the user wants the support plate 19 to be in a relatively inclined state, the mounting base 13 at the bottom can be moved upward. The mounting base 13 at the bottom drives the second ear seat 22 at the bottom to move upward, thereby driving the linkage plate 21 to rotate, and then driving the support plate 19 to rotate, which plays a role in adjusting the inclination angle of the support plate 19.

[0068] At the same time, in order to make the bottom of the bottom plate 32 and the bottom of the column 12 on the same axis, at this time, the mounting base 13 at the top needs to be moved downward to compensate for the position difference caused by the inclination of the support plate 19. Then, the mounting plate 14 is placed on one side of the mounting base 13. When the rotating rod 15 is rotated, the rotating rod 15 is located in the inner cavity of the groove 16 and is horizontally placed. Further, a second threaded nut 17 is sleeved on the outer threaded surface of the rotating rod 15 and rotated. One side of the second threaded nut 17 is in close contact with the mounting plate 14, which can play a role in positioning the mounting base 13 and achieve the purpose of improving the stability of the column 12, that is, the conversion beam.

[0069] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
