Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a high-precision prefabricated reinforced concrete frame connection structure. Background Art

[0002] Prefabricated reinforced concrete frame connection structure is a key part of prefabricated concrete structure. It is mainly used to connect prefabricated concrete columns, beams and other components into an integral frame structure, so that the structure can effectively transfer loads and ensure the safety and stability of the building during use. The connection methods are divided into: wet connection and dry connection. The wet connection method is to pour high-strength grouting material at the node. After the grouting material solidifies, the frame is firmly connected together, while the dry connection is connected by bolts. Bolt holes are pre-set on the prefabricated components, and the components are connected together by bolts. Welding can also be used for fixing. The steel bars or embedded parts of the prefabricated components are connected by welding.

[0003] Bolt connections are widely used because of their high stability and low requirements for the installation environment. However, bolt connections require high precision to ensure accurate matching between bolts and holes. The tolerances allowed for prefabricated parts are more stringent. During assembly, the beam is in a hoisting state. Since the reserved tolerance of the connector is small and the beam is always in a moving state, it is difficult for the beam to be accurately embedded in the connector. The workers' proficiency is required to be high, which has a negative impact on assembly efficiency. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-10 The embodiment of the present invention provides a high-precision prefabricated reinforced concrete frame connection structure, comprising a first prefabricated part 1 and a second prefabricated part 2, wherein the upper end of the first prefabricated part 1 is fixedly sleeved with a first mouth sleeve 3, and the lower end of the first prefabricated part 1 is fixedly sleeved with a second mouth sleeve 4, and further comprising:

[0033] A supporting structure 5, the supporting structure 5 is used to support the second prefabricated component 2, and the supporting structure 5 includes a base 51 and guard plates 52 fixed on both sides thereof;

[0034] A guide assembly, the guide assembly is used to guide the second preform 2 so that it can be smoothly embedded in the support structure 5, the guide assembly includes a first guide structure 6 and a second guide structure 7, the first guide structure 6 guides the second preform 2 in the X-axis direction, the second guide structure 7 guides the second preform 2 in the Y-axis direction, the second mechanism 7 includes a flip plate 71, a central axis 72, and a slide groove 73, the slide groove 73 is opened on the guard plate 52, the central axis 72 is slidably connected in the slide groove 73, the flip plate 71 is fixedly installed on the central axis 72, the flip plate 71 has a first position and a second position, in the first position, the central axis 72 is at the top of the slide groove 73 and the flip plate 71 is in an inclined state, in the second position, the central axis 72 is at the bottom of the slide groove 73 and the flip plate 71 is in a vertical state;

[0035] The locking structure 8 is used to lock the first enveloping sleeve 3 and the second enveloping sleeve 4. The locking structure 8 includes a bolt member 83, a threaded block 89 and a transmission part. The bolt member 83 is rotatably connected in the first enveloping sleeve 3, and the threaded block 89 is arranged in the second enveloping sleeve 4. The bolt member 83 and the flip plate 71 are connected through the transmission part. When the flip plate 71 is switched from the first position to the second position, under the transmission action of the transmission part, the bolt member 83 is screwed into the threaded block 89 to fix the first enveloping sleeve 3 and the second enveloping sleeve 4.

[0036] In the embodiment of the present invention, the first prefabricated member 1 is a column, the second prefabricated member 2 is a beam, and the first cover sleeve 3 and the second cover sleeve 4 are respectively provided at the upper and lower ends of the first prefabricated member 1. When a pair of first prefabricated members 1 are assembled, the adjacent first cover sleeves 3 and the second cover sleeves 4 on the pair of first prefabricated members 1 are fixedly connected together;

[0037] The support structure 5 is arranged outside the first mouth sleeve 3, and a support block is arranged at the lower part of the first mouth sleeve 3 to support the base 51, so as to ensure that the base 51 can carry the second preform 2. The guard plates 52 are distributed on both sides of the base 51, and the position of the second preform 2 in the X direction can be limited;

[0038] The function of the guide assembly is to guide the second prefabricated part 2 when the second prefabricated part 2 is hoisted to the base 51, so that the second prefabricated part 2 can be smoothly placed on the base 51. The guide assembly is composed of a first guide structure 6 and a second guide structure 7. The first guide structure 6 guides the second prefabricated part 2 in the X-axis direction so that the second prefabricated part 2 can smoothly enter between a pair of guard plates 52, and the second guide structure 7 guides the second prefabricated part 2 in the Y-axis direction so that the second prefabricated part 2 is located between the two first prefabricated parts 1 in the horizontal direction, so as to ensure that when supporting the two ends of the second prefabricated part 2, the two ends of the second prefabricated part 2 can be balanced in force. The flip plate 71 is tilted in the first position, and the end of the second prefabricated part 2 contacts the flip plate. 71 can be guided so that the two ends of the second preform 2 can evenly contact the base 51 to ensure that the forces on the two ends of the base 51 are balanced. Because the flip plate 71 is in an inclined state, the area covered by the flip plate 71 is larger. As long as the second preform 2 falls into the range of the flip plate 71 when it is hoisted and dropped, the second preform 2 squeezes the flip plate 71, and the central axis 72 slides along the slide groove 73. In the sliding process, the flip plate 71 is flipped so that it is flipped from the inclined state to the vertical state. The vertical surface of the flip plate 71 just fits the end surface of the second preform 2. As the flip plate 71 and the second preform 2 fall, under the guidance of the flip plate 71, the second preform 2 will fall to the base 51, which helps to improve the assembly efficiency.

[0039] The locking structure 8 is driven by the movement of the flip plate 71 during the guiding process. The first cover sleeve 3 and the second cover sleeve 4 can be locked by the locking structure 8, so that a pair of first prefabricated parts 1 can be fixed to ensure the stability of the first prefabricated part 1. The bolt member 83 is rotatably connected in the first cover sleeve 3, and the threaded block 89 is arranged in the second cover sleeve 4. In the process of the flip plate 71 moving from the first position to the second position, the transmission part receives the trend of the flip plate 71, so that the transmission shaft 81 drives the bolt member 83 to rotate. During the rotation of the bolt member 83, the threaded block 89 is screwed into the bolt member 83. Through the cooperation of the threaded block 89 and the bolt member 83, the first cover sleeve 3 and the second cover sleeve 4 are fixedly connected, without the need for manual climbing and locking. The fixing of adjacent first prefabricated parts 1 is convenient and quick, and the bolt member 83 is hidden in the second cover sleeve 4, which does not affect the subsequent assembly of wall panels and other components.

[0040] In the embodiments of the present invention, please refer to Figure 2 The first guide structure 6 includes a base plate 61, a fixed clamping plate 62, and a movable clamping plate 63. The base plate 61 is slidably connected to the supporting structure 5, the fixed clamping plate 62 is fixedly installed on the base plate 61, and the movable clamping plate 63 is hinged to the upper part of the fixed clamping plate 62.

[0041] The base plate 61 is slidably connected to both sides of the guard plate 52. When the second preform 2 falls, the second preform 2 and the movable clamp 63 of the base plate 61 come into contact. First, the base plate 61 is forced to move downward, and the movable clamp 63 will move downward synchronously, so that the movable clamp 63 will gradually rotate into a vertical state. During the rotation process, the second preform 2 can be squeezed to achieve its correction. The second preform 2 is displaced toward between the two guard plates 52. In this way, the position of the second preform 2 in the X-axis direction is changed by the movable clamp 63, so that it can fall smoothly onto the base 51 to achieve automatic correction of the second preform 2. The spacing between a pair of fixed clamps 62 is adapted to the second preform 2. In this way, the assembly accuracy of the second preform 2 is greatly improved.

[0042] In the embodiments of the present invention, please refer to Figure 2-3 , includes an elastic member 64, and the elastic member 64 applies an upward thrust to the substrate 61.

[0043] By setting the elastic member 64, in the absence of other external forces, the base plate 61 is at the highest point, and the movable splint 63 protrudes above the guard plate 52, so that the movable splint 63 can tilt outward to ensure that there is sufficient coverage area to ensure that the movable splint 63 can smoothly receive the second preform 2.

[0044] In another embodiment of the present invention, please refer to Figure 2 When the flip plate 71 is in the first position, one side of the fixing clamping plate 62 abuts against the lower portion of the flip plate 71 .

[0045] Under the elastic force of the elastic member 64, the base plate 61 is at the highest point, and the upper part of the fixed clamping plate 62 abuts against the flip plate 71, so the fixed clamping plate 62 also applies a thrust to the flip plate 71. Under the thrust, the flip plate 71 is ensured to be at the upper part of the slide groove 73 and maintain an inclined state. Therefore, the first guide structure 6 not only has a guiding function, but also has a fixing function for the flip plate 71. In this way, the flip plate 71 can maintain the first position without any other additional settings.

[0046] During the guiding process of the movable splint 63, since the fixed splint 62 is in contact with the bottom of the flip plate 71, the base plate 61 is at the highest point at this time. When squeezed by the second preform 2, the base plate 61 cannot move upward. Therefore, the movable splint 63 is prevented from flipping outward due to this pressure, ensuring that the movable splint 63 can only flip inward.

[0047] In the embodiments of the present invention, please refer to Figure 2 and 10The slide groove 73 includes a turning groove 731 and a falling groove 732 , and the falling groove 732 is connected to the lower part of the turning groove 731 .

[0048] When the flip plate 71 is under pressure, the center axis 72 first slides along the flip groove 731 and rotates synchronously to ensure that the flip plate 71 is flipped from an inclined state to a vertical state, and the lower part of the flip plate 71 will also move in the opposite direction away from the second preform 2 to ensure that the vertical surface of the flip plate 71 can be smoothly attached to the end surface of the second preform 2.

[0049] In the embodiments of the present invention, please refer to Figure 4-8 The transmission part includes a transmission shaft 81, a first gear 82, a second gear 84, a third gear 85, and a rack 86. The transmission shaft 81 is rotatably connected in the first bag sleeve 3. The first gear 82 and the third gear 85 are fixedly sleeved on the transmission shaft 81. The second gear 84 is fixedly sleeved on the lower part of the bolt member 83. The rack 86 is fixed on the back of the flip plate 71.

[0050] When the flip plate 71 moves from the first position to the second position, the third gear 85 and the rack 86 are meshed.

[0051] During the flipping process of the flip plate 71, the rack 86 will change to a vertical state and mesh with the third gear 85. At this time, the back of the flip plate 71 is attached to the outside of the first bag mouth sleeve 3, and the flip plate 71 continues to descend under the extrusion of the second preform 7. Therefore, the third gear 85 will rotate. When the third gear 85 rotates, it can drive the transmission shaft 81 to rotate. When the transmission shaft 81 rotates, it can drive the first gear 82 to rotate. When the first gear 82 rotates, it can synchronously drive the second gear 84 meshed with it to rotate. When the second gear 84 rotates, the bolt member 83 will rotate synchronously. See the attached Figure 5 At this time, when the flip plate 71 is in the first position, the bolt member 83 and the threaded block 89 are not connected together, but the bolt member 83 abuts against the threaded block 89. As the bolt member 83 rotates, as shown in the attached Figure 7 As shown, the bolt member 83 is screwed into the threaded block 89, so that the first cover sleeve 3 and the second cover sleeve 4 are fixedly connected together through the cooperation of the two.

[0052] In the embodiment of the present invention, a rectangular hole 41 is provided in the second enclosing sleeve 4 , and the threaded block 89 is slidably connected in the rectangular hole 41 .

[0053] The rectangular hole 41 is provided to ensure that the threaded block 89 can only move in the vertical direction within the rectangular hole 41 , so as to ensure that the bolt member 83 can be screwed in smoothly.

[0054] In the embodiments of the present invention, please refer to Figure 5 , Figure 7 A fixing block 87 is fixedly installed at the lower part of the rectangular hole 41, and the bolt member 83 rotates through the fixing block 87 and then is inserted into the rectangular hole 41. A cushion block 88 is arranged on the upper part of the fixing block 87. When the flip plate 71 is switched from the first position to the second position, the bolt member 83 rotates and the threaded block 89 moves downward, so that the fixing block 87, the cushion block 88 and the threaded block 89 overlap.

[0055] The bolt member 83, the gasket 88 and the threaded block 89 are tightly fitted under pressure, which effectively prevents the bolt member 83 and the threaded block 89 from loosening, and the thickness of the gasket 88 is adjustable, which can be appropriately adjusted according to actual needs. The gasket 88 can also be selected to have a polyurethane elastic block. In this way, by tightening the threaded block 89, the polyurethane elastic block will produce a certain deformation under the great extrusion pressure, which can not only prevent loosening, but also better adapt to the number of rotations of the bolt member 83.

[0056] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
