Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a fully prefabricated concrete connection structure based on standardized components. Background Technology

[0002] Many existing prefabricated buildings neglect the coordination between different architectural disciplines and the characteristics of architectural art, generally overemphasizing the main structure and mainly adopting a boxy shape. Existing prefabricated concrete building structures lack modular standardized designs, and the diverse forms of prefabricated components make mass production difficult.

[0003] In terms of wet-process connection joints, due to factors such as dense reinforcement, small space, small and thin concrete volume, and difficulty in interface treatment, it is difficult to guarantee the quality of concrete in human processes such as vibration and curing. Theoretically strong joints will become weak joints in practice. In addition, the influence of construction climate environment may lead to problems such as drying shrinkage and cracks, which may make the quality even more uncontrollable. In terms of dry-process connection joints, most of them fail to achieve the same effect as the reinforcement stress of cast-in-place concrete structures. Summary of the Invention

[0019] (III) Beneficial Effects

[0020] This invention provides a fully prefabricated concrete connection structure based on standardized components. The main structure is formed by precast columns, precast shear walls, precast beams, precast slabs, and precast lightweight walls. Precast components are placed at the connection points where any two components connect, and the connection is achieved through these precast components. When precast columns, shear walls, beams, slabs, and lightweight walls are precast, first and / or second precast components are simultaneously precast on their inner sides. During installation, locking bolts are used to connect and fix the first and second precast components. This application precasts the connection nodes between columns and beams, columns and walls, etc., as a whole. Standardized vibration and curing operations are achieved throughout the precast process. This precast operation is not limited by the construction site or climate, and achieves dry connection and fixation, meeting the design principle of "strong nodes, weak components" and the requirement that nodes are equivalent to cast-in-place structures, thus avoiding problems such as drying shrinkage and cracks.

[0021] Finally, this application utilizes prefabricated columns, prefabricated shear walls, prefabricated beams, prefabricated slabs, prefabricated lightweight walls, and prefabricated components to standardize all structural components during construction, facilitating prefabrication and on-site construction. The connections between prefabricated columns, prefabricated shear walls, prefabricated beams, prefabricated slabs, and prefabricated lightweight walls are achieved through prefabricated components, realizing a dry connection of the reinforcing steel between two main structures. This is equivalent to the reinforcing steel load-bearing effect of cast-in-place structures, allowing this connection structure to be adapted to different structural systems.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] First Embodiment

[0035] This invention provides a fully prefabricated concrete connection structure based on standardized components, see [link to relevant documentation]. Figures 1 to 4 It includes precast columns 100, precast shear walls 200, precast beams 300, precast slabs 400, and precast lightweight walls 500; the precast columns 100, precast beams 300, and precast slabs 400 are interconnected to form a frame, and the precast shear walls 200 and precast lightweight walls 500 are connected to the vertical side of the frame; during construction, the precast columns 100 are set vertically, the precast beams 300 and precast slabs 400 are set horizontally, and the precast shear walls 200 and precast lightweight walls 500 are set vertically, forming a prefabricated building after enclosure.

[0036] During construction, there are multiple connection points when any two of the precast column 100, precast shear wall 200, precast beam 300, precast slab 400 and precast lightweight wall 500 are connected. At each connection point, a precast component is set, that is, the connection and fixation are achieved through multiple precast components. It should be explained that "any two" here refers to the connection of two identical precast columns 100, precast shear walls 200, precast beams 300, precast slabs 400, and precast lightweight walls 500, for example, the connection between precast columns 100 and precast columns 100, or the connection between precast shear walls 200 and precast shear walls 200. Similarly, "any two" here also includes the connection of two different precast columns 100, precast shear walls 200, precast beams 300, precast slabs 400, and precast lightweight walls 500, for example, the connection between precast columns 100 and precast beams 300, or the connection between precast beams 300 and precast slabs 400, in which case precast components will be set at the connection points.

[0037] Specifically, the prefabricated components include a first prefabricated component 600, a second prefabricated component 700, and a locking screw 800.

[0038] At the connection points of the precast columns 100, precast shear walls 200, precast beams 300, precast slabs 400, and precast lightweight walls 500, first precast components 600 or second precast components 700 are precast, and at each connection point, the first precast component 600 and the second precast component 700 are connected by locking screws 800. For example, in the connection between the precast beam 300 and the precast shear wall 200, the first precast component 600 is provided on the side of the precast beam 300 near the precast shear wall 200, and the second precast component 700 is provided on the side of the precast shear wall 200 near the precast beam 300. During installation, the first precast component 600 and the second precast component 700 are connected and fixed by locking screws 800. Similarly, the second precast component 700 can be provided on the precast beam 300, and the first precast component 600 can be provided on the precast shear wall 200; the method is not limited thereto.

[0039] The first precast component 600 includes a locking sleeve 610 and a first reinforcing bar 620. The locking sleeve 610 has an internal thread on its inner side, and both ends of the locking sleeve 610 are through.

[0040] The locking sleeve 610 and the first reinforcing bar 620 are prefabricated on the inner side of the precast column 100, precast shear wall 200, precast beam 300, precast slab 400 or precast lightweight wall 500. One end of the locking sleeve 610 is close to the connection position and forms a first mounting hole 611 with the side where the connection position is located. The threaded end 820 of the locking screw 800 passes through the first mounting hole 611 and is threadedly connected to the locking sleeve 610.

[0041] One end of the first reinforcing bar 620 forms a first threaded section, and the other end is threadedly connected to the first threaded section. The first reinforcing bar 620 is embedded in the section away from the first threaded section and passes through the inner side of the precast column 100, precast shear wall 200, precast beam 300, precast slab 400, or precast lightweight wall 500. It can be understood that when the first precast component 600 is embedded in the precast column 100, that is, the locking sleeve 610 is located in the precast column 100, the first reinforcing bar 620 is also embedded inside the precast column 100.

[0042] When the locking sleeve 610 is embedded in the precast column 100, precast shear wall 200, precast beam 300, precast slab 400, or precast lightweight wall 500, a limiting hole 612 is provided on the outer circumference of the locking sleeve 610 to further enhance the connection strength. The limiting hole 612 is not connected to the inside of the locking sleeve 610. After prefabrication, the limiting hole 612 is squeezed by the outer concrete, thus creating a limiting effect on the locking sleeve 610. After construction, the connection between the locking sleeve 610 and the concrete is tighter. At the same time, the connection between any two building materials is more stable after the precast components are assembled.

[0043] In one embodiment, the second precast component 700 includes a first connecting box 710, a reinforcing sleeve 720, a connecting bolt 730, and a second reinforcing bar 740.

[0044] Specifically, one end of the first connecting box 710 is close to the connecting position, and a second mounting hole 711 is formed on the side where the connecting position is located; the nut end 810 of the locking screw 800 is located inside the first connecting box 710, and the threaded end 820 of the locking screw 800 passes through the second mounting hole 711.

[0045] The first connecting box 710 has a first connecting hole 712 at one end away from the second mounting hole 711. One end of the connecting bolt 730 is located inside the first connecting box 710, and the other end extends out from the first connecting hole 712 and is threadedly connected to the reinforcing sleeve 720.

[0046] One end of the second reinforcing bar 740 has a second threaded section, and is threadedly connected to the reinforcing sleeve 720 through the second threaded section; the bar segment of the second reinforcing bar 740 away from the second threaded section is embedded and passes through the inner side of the precast column 100, precast shear wall 200, precast beam 300, precast slab 400 or precast lightweight wall 500.

[0047] Understandably, during prefabrication, the second precast component 700 is first assembled, and then it is embedded as a whole into the inner side of the precast column 100, precast shear wall 200, precast beam 300, precast slab 400, or precast lightweight wall 500. The connecting bolt 730 has a bolt cap at one end inside the first connecting box 710, which acts as a limit to prevent it from falling out of the first connecting hole 712. The second reinforcing bar 740, at one end outside the reinforcing sleeve 720, is also connected and fixed to the concrete, serving the purpose of fixation and increasing shear force.

[0048] The first connecting box 710 has a first assembly port 713. One end of the first assembly port 713 is connected to the interior of the first connecting box 710, and the other end is connected to the outside of the precast column 100, precast shear wall 200, precast beam 300, precast slab 400, or precast lightweight wall 500. For example, when the first connecting box 710 is installed inside the precast column 100, the first assembly port 713 will penetrate one side or one end of the precast column 100. The first assembly port 713 is connected to the outside of the precast column 100, so that during construction, the locking screw 800 can be operated from the outside for connection and fixation. Understandably, in order to facilitate construction and operation, the length of the locking screw 800 and the size of the first assembly port 713 should meet the following conditions: the locking screw 800 can enter the first connecting box 710 through the first assembly port 713, and when locking, the locking screw 800 can pass through the second mounting hole 711 and the first mounting hole 611 to connect and lock the locking sleeve 610.

[0049] The cross-section of the first connecting box 710 can be semi-circular or rectangular, and is not limited thereto.

[0050] In this embodiment, the second precast component 700 is equipped with a first connecting box 710, a reinforcing sleeve 720, a connecting bolt 730, and a second reinforcing bar 740. Through this structural connection, after prefabrication, the connection strength with the precast column 100, precast shear wall 200, precast beam 300, precast slab 400, or precast lightweight wall 500 can be significantly improved. During manufacturing, the second precast component 700 can be selected on the side with sufficient dimensions and higher load-bearing requirements. Therefore, after construction, the structure has a stronger load-bearing capacity.

[0051] During construction, after the prefabricated components are installed, a first high-strength, non-shrink, fast-hardening sealing putty block 750 is placed at the first assembly opening 713. Specifically, the first high-strength, non-shrink, fast-hardening sealing putty block 750 is formed by sealing the first assembly opening 713 with high-strength, non-shrink, fast-hardening sealing putty.

[0052] The outer surface of the reinforcing sleeve 720 is integrally formed with reinforcing ridges 721, both ends of which are located in the middle section of the outer surface of the reinforcing sleeve 720. In this application, "middle section" refers to any position other than the two ends. By providing reinforcing ridges 721, the connection strength between the reinforcing sleeve 720 and the concrete can be further improved. At the same time, the reinforcing ridges 721 form a limiting effect on the inner side of the concrete, preventing the reinforcing sleeve 720 from sliding outward during or after construction.

[0053] See Figures 6-7 The locking screw 800 includes a nut end 810, a threaded end 820, and a support rod section 830. The support rod section 830 is located between the nut end 810 and the threaded end 820, and its diameter is larger than that of the threaded end 820. A support sleeve section 613 is formed at the end of the locking sleeve 610 near the first mounting hole 611. During installation, the support rod section 830 is inserted into the support sleeve section 613. With the locking screw 800, after assembly, the support sleeve section 613 provides transition support at the connection point, and the threaded end 820 locks the end. This ensures both the connection strength of the prefabricated components at the connection point and the overall locking effect of the prefabricated components.

[0054] For ease of explanation, the two sides of the connection position are named the first connector 900a and the second connector 900b, respectively. It can be understood that the first connector 900a and the second connector 900b can be precast columns 100, precast shear walls 200, precast beams 300, precast slabs 400 or precast lightweight walls 500.

[0055] An interface agent layer 910 and a high-strength, non-shrink grout layer 920 are applied to the side of the first connector 900a and the second connector 900b that are close to each other. During construction, the interface agent is first applied to the side of the first connector 900a and the second connector 900b that are close to each other to form the interface agent layer 910. Then, after assembly, the high-strength, non-shrink grout is injected into the gap to form the high-strength, non-shrink grout layer 920.

[0056] The first connector 900a has a long groove 930 along its length on one side near the connection position, and the second connector 900b has a protruding ridge 940 on one side near the connection position. The protruding ridge 940 is fitted into the long groove 930. Precast components are provided on both sides of the long groove 930 and the protruding ridge 940. Through the long groove 930 and the protruding ridge 940, this structure provides positioning and splicing during installation. After installation, the structure can withstand a certain amount of force, thus protecting the precast components to a certain extent and improving the overall strength of the building structure.

[0057] Even better, for ease of installation, the 940 convex ridge could also be designed with a stepped design.

[0058] This application prefabricates long grooves, protruding ridges, and other structures simultaneously when prefabricating precast columns 100, precast shear walls 200, precast beams 300, precast slabs 400, or precast lightweight walls 500. This allows for the overall prefabrication of connection nodes between columns and beams, and between columns and walls. Standardized vibration and curing operations are achieved throughout the prefabrication process. Moreover, this prefabrication method is not limited by the construction site or affected by the climate. It achieves dry connection and fixation of nodes, meeting the design principle of "strong nodes and weak components" and the requirement that nodes are equivalent to cast-in-place construction, thus avoiding problems such as drying shrinkage and cracks.

[0059] See Figures 8 to 9 In one embodiment, a support rib 110 is provided on the side of the precast column 100, precast shear wall 200, precast beam 300, and precast lightweight wall 500 near the connection position. During installation, the building on the other side of the connection position will abut against the support rib 110, which serves as a support, while the precast components serve as a connection and fixation mechanism, further reducing the workload of the precast components and ensuring the overall stability and safety of the building structure. During prefabrication, the support rib is simultaneously vibrated and cured, ensuring that the design principle of "strong node, weak component" and the requirement that nodes are equivalent to cast-in-place structures are met after construction.

[0060] Second Embodiment

[0061] In this embodiment, see Figure 5 The difference from the first embodiment is the second preform 700.

[0062] The second precast component 700 includes a second connecting box 760 and a third reinforcing bar 770.

[0063] One end of the second connecting box 760 is close to the connection position, and a third mounting hole 761 is formed on the side where the connection position is located. The nut end 810 of the locking screw 800 is located inside the second connecting box 760, and the threaded end 820 of the locking screw 800 passes through the third mounting hole 761.

[0064] The second connecting box 760 has a second connecting hole 763 at the end away from the third mounting hole 761; one end of the third reinforcing bar 770 has a third threaded section, and the end of the third reinforcing bar 770 near the third threaded section is connected to the second connecting hole 763.

[0065] Specifically, in one method, the third threaded segment can be threaded to the second connecting hole 763. This connection method can improve construction efficiency and save costs. During construction, by selecting second connecting boxes with different wall thicknesses, the connection can meet the load-bearing requirements of both load-bearing and non-load-bearing walls. Specifically, for the second connecting box located at the load-bearing wall position, the side wall near the second connecting hole can be made thicker, while the side wall at the non-load-bearing wall position can be made thinner.

[0066] In another embodiment, a locking nut 780 is provided inside the second connecting box 760, and the third threaded segment enters the second connecting box 760 through the second connecting hole 763. The locking nut 780 is threadedly connected to the third threaded segment from the inside of the second connecting box 760.

[0067] By directly threading the third threaded section to the second connecting hole, construction efficiency can be improved and costs can be saved. By using a locking nut 780 to thread the third threaded section inside the second connecting box 760, it can be fixed to the third reinforcing bar 770 from the inside of the second connecting box 760, thereby improving the connection strength and ensuring the safety and certainty of the connection node.

[0068] The other end of the third reinforcing bar 770 is located outside the second connecting box 760. The third reinforcing bar 770 is embedded in the bar segment away from the third threaded segment and passes through the inner side of the precast column 100, precast shear wall 200, precast beam 300, precast slab 400 or precast lightweight wall 500.

[0069] During the prefabrication process, the second connecting box 760, the third reinforcing bar 770, and the locking nut 780 are all embedded in the concrete, specifically located inside the prefabricated column 100, prefabricated shear wall 200, prefabricated beam 300, prefabricated slab 400, or prefabricated lightweight wall 500.

[0070] The second connecting box 760 has a second assembly port 762. One end of the second assembly port 762 is connected to the inside of the second connecting box 760, and the other end is connected to the outside of the precast column 100, precast shear wall 200, precast beam 300, precast slab 400 or precast lightweight wall 500. A second high-strength non-shrinkage fast-hardening sealing mortar block 790 is provided at the second assembly port 762.

[0071] The cross-section of the second connecting box 760 can be semi-circular or rectangular, and is not limited here.

[0072] In this embodiment, the second precast component 700 is only provided with a second connecting box 760, a third reinforcing bar 770 and a locking nut 780. After installation, its strength is lower than that of the structure in the first embodiment, and its size is relatively shorter. During prefabrication, a non-load-bearing structure can be selected, such as a precast lightweight wall 500.

[0073] In summary, the present invention provides a fully assembled concrete connection structure based on standardized components. The main structure is formed by precast columns 100, precast shear walls 200, precast beams 300, precast slabs 400 and precast lightweight walls 500. Precast components are set at the connection points where any two components are connected in this structure, and the connection is achieved through the precast components. When prefabricating precast columns 100, precast shear walls 200, precast beams 300, precast slabs 400, and precast lightweight walls 500, the first precast component 600 and / or the second precast component 700 are simultaneously prefabricated on their inner sides. Structures such as long grooves and protruding ridges are also prefabricated simultaneously. The connection nodes between columns and beams, columns and walls, etc., are prefabricated as a whole. Standardized vibration and curing operations are achieved as a whole during the prefabrication process. Moreover, this prefabrication operation is not limited by the construction site or affected by the climate. It achieves dry connection and fixation of the nodes, meets the design principle of "strong nodes and weak components" and the requirement that the nodes are equivalent to cast-in-place, and avoids problems such as drying shrinkage and cracks.

[0074] Finally, this application utilizes prefabricated columns, prefabricated shear walls, prefabricated beams, prefabricated slabs, prefabricated lightweight walls, and prefabricated components to standardize all structural components during construction, facilitating prefabrication and on-site construction. The connections between prefabricated columns, prefabricated shear walls, prefabricated beams, prefabricated slabs, and prefabricated lightweight walls are achieved through prefabricated components, realizing a dry connection of the reinforcing steel between two main structures. This is equivalent to the reinforcing steel load-bearing effect of cast-in-place structures, allowing this connection structure to be adapted to different structural systems.
