Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated concrete component connectors, and in particular to a prefabricated component connector, a prefabricated component assembly and a connection method. Background Art

[0002] Precast components refer to concrete parts that are processed and produced in a standardized, mechanized manner in a factory, such as precast piles, precast beams, etc. During the construction of prefabricated buildings, it is necessary to support the upper building structure through prefabricated columns. The technical solution generally adopted by the common prefabricated building structure is that when pre-embedded steel bars are extended from the upper and lower ends of the prefabricated support column, the pre-embedded steel bars are also extended from the two ends of the beam for a distance when the beam is horizontally overlapped with the top of the support column for supporting the floor slab. When assembled, the prefabricated column that plays a vertical supporting role is generally erected first, and its lower end is fixed firmly by pouring and other methods, and then the supporting beam or supporting longitudinal beam for horizontal support and longitudinal support is overlapped on the top of the column. The ends of the two supporting beams close to the support column are overlapped on the top of the support column respectively, and the ends of the two supporting longitudinal beams close to the support column are also overlapped on the top of the support column respectively, and the steel bars extending from the ends of the beams and the longitudinal beams are bundled. Similarly, the top of the prefabricated support column below the supporting beam and the supporting longitudinal beam and the bottom of the prefabricated support column above are also overlapped by tying the end steel bars, and then the part where the steel bars are tied is cast in place.

[0003] There are many problems with the above construction method. First, the embedded steel bars extending from the ends of the precast concrete components are prone to rust and damage during transportation and construction, which has an adverse effect on the subsequent construction quality. At the same time, multiple steel bars extending outward are easy to cause harm to construction workers, which is not conducive to ensuring their life safety and health. Secondly, since the supporting crossbeams and supporting longitudinal beams are subject to large forces, the steel bars at the overlapped parts are only tied together, and the tensile strength and mechanical properties are not good, which poses a safety hazard. In addition, the bundling process is extremely complicated and time-consuming. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problems existing in the connection and casting process of the overlapping parts of the existing prefabricated components of assembled buildings.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] <Example 1>

[0032] like Figures 1 to 5 As shown, a prefabricated component connector 10 provided in this embodiment includes a first connector 1, a second connector 2, a spring 3, an inner nesting member 4, a meson 5, an inner sleeve 6 and an insertion rod 7. The inner nesting member 4 is arranged in the accommodating cavity 21 of the second connector 2, and the meson 5 abuts against the inner nesting member 4 through an inclined surface 51, so that the meson 5 can move relative to the inner nesting member 4 through the inclined surface. The inner sleeve 6 is arranged at one end of the meson 5, and the spring 3 is arranged in the accommodating cavity 21 and one end abuts against the inner sleeve 6. The insertion rod 7 is provided with a connecting portion 71 at one end and an end portion 72 at the other end. A rod body 73 is provided between the connecting portion 71 and the end portion 72. The connecting portion 71 is used to connect with the first connector 1, and the end portion 72 is used to be inserted into the accommodating cavity 21 and positioned by the meson 5. A constricted portion 74 is provided between the rod body 73 and the end portion 72. After the end portion 72 is inserted into the accommodating cavity 21, the constricted portion 74 is clamped with the meson 5. In the above technical scheme, when the prefabricated component connector is used, the various components need to be assembled and connected. The connecting portion 71 of the plug rod 7 is connected to the connector 1. When the end portion 72 of the plug rod 7 is inserted downward into the second connector 2, the meson 5 and the inner sleeve 6 are pushed to move and compress the spring 3. The inner edge of the meson 5 will be subjected to the pressure of the outer wall of the end portion 72 and expand outward. The inner hole of the meson 5 becomes larger, allowing the end portion to pass through. The end portion 72 continues to move into the interior of the spring 3. When the end portion is completely inside the spring 3, the meson is no longer subjected to the squeezing force of the end portion, so it is reset and the shrinking neck 74 is stuck out to ensure that the end portion will not fall out. Through the above technical scheme, it is easy to assemble and connect the prefabricated components, convenient to operate, and improve assembly efficiency and safety. In this embodiment, the first and second connectors are nuts, and the spring is a cylindrical spring.

[0033] Furthermore, the length of the inserted rod 7 is 5 to 20 times the sum of the depths of the first connecting member 1 and the second connecting member 2, which can facilitate the assembly of the upper and lower support columns without affecting the overlapping process of the ends of the cross beam and the longitudinal beam at the upper end of the support column, while also leaving enough space for pouring concrete at the overlapping parts.

[0034] Furthermore, a plurality of mesons 5 are arranged at intervals around the axis 20 of the second connecting member 2, and there is a gap 51 between adjacent mesons 5, so that when the end portion 72 is inserted, the meson 5 can be synchronously pushed to move and expand.

[0035] Furthermore, the outer wall of the inner nested component 4 is threadedly connected to the inner wall of the second connecting component 2, and one end of the inner sleeve 4 is provided with an inclined surface corresponding to the outer wall of the meson 5, so as to facilitate the assembly and disassembly of the inner nested component 4 and the second connecting component 2, and the meson 5 can slide through the inclined surface to expand or contract.

[0036] Furthermore, the accommodating cavity 21 has an expansion cavity 211, and the inner sleeve 6 is arranged in the expansion cavity 211. The outer diameter of the inner sleeve 6 is smaller than the inner diameter of the expansion cavity 211. When the meson 5 is pushed, the inner sleeve 6 moves in the expansion cavity, and the meson can slide to the expansion cavity 211 to expand outward, so that the end head passes through.

[0037] Furthermore, the connecting portion 71 is threadedly connected to the first connecting member 1, so as to facilitate the assembly of the plug rod and the first connecting member 1. The end portion 72 is spherical, so as to be able to push the meson 5.

[0038] Furthermore, the rod body 73 has threads, the first locking sleeve 81 is threadedly connected to the rod body 73 and presses against the first connecting member 1, and the second locking sleeve 82 is threadedly connected to the rod body and presses against the second connecting member 2, thereby further improving the connection stability of the two ends of the insertion rod.

[0041] like Figure 6 As shown, relative to the first embodiment, this embodiment provides a prefabricated component combination, including a plurality of prefabricated components, and the prefabricated components are connected by prefabricated component connectors 10.

[0042] Furthermore, the plurality of prefabricated components include an upper support column 100, a lower support column 200 and a support beam 300, the upper and lower support columns are connected by a plurality of prefabricated component connectors 10, the support beams 300 are connected by a plurality of prefabricated component connectors 10, and there is a cast-in-place concrete formwork 400 between the support columns and the support beams. In the above technical solution, when the upper and lower support columns and the support beams 300 are assembled, a concrete pouring area S is formed, the prefabricated component connectors 10 are covered by cast-in-place concrete, and the cast-in-place concrete formwork 400 is used to block and shape, so that an integrated stable structure is formed between the prefabricated components.

[0043] <Example 3>

[0044] In this embodiment, the same parts as those in Embodiments 1 and 2 are given the same figure marks, and the same text descriptions are omitted.

Through the screw-type connector, it is easy to quickly connect the beam ends and the column ends through the bolt structure, avoiding the problems of difficult bundling, insufficient mechanical performance, and greater safety hazards in the prior art of using steel bar bundling, and facilitating the pouring of concrete at the overlapped parts.

[0046] In the above-mentioned embodiments 1 to 3, during the working process, as the working environment changes, some technical implementation methods of embodiments 1 to 5 can be combined or replaced.
