The utility model belongs to the technical field of the building technique and specifically relates to a post roof beam connected node, building frame construction and building body are related to.

Background

According to Chinese building energy consumption research report (2017) issued by the Chinese building energy conservation Association, it is shown that steel products of 1/3 nationwide, 60-70% of cement, 1/3 urban construction land, 1/3 urban water and 40-50% of energy are consumed in the whole life cycle of the house building, and the influence on energy, resources and environment is huge. The traditional building industry is a highly-polluted, highly-energy-consuming and environment-unfriendly industry, has low industrialization degree, large water consumption, energy consumption, artificial garbage and sewage discharge amount, does not accord with the national sustainable development policy of energy conservation and environmental protection, and needs a large amount of labor force.

In recent years, with the continuous improvement of living standard of people, the requirements of people on building speed, building cost, construction quality, energy conservation, environmental protection and the like in the building industry such as houses and the like are also continuously improved, and in order to save resources and energy, reduce construction pollution, improve labor production efficiency and quality safety level, develop green buildings and advanced construction modes, the nation advocates a modern assembly type building system from 2016. The development of the assembly type building is a great change of the construction mode, is an important measure for promoting the structural reform of the supply side and the novel urbanization development, is favorable for saving resource and energy, reducing construction pollution, improving labor production efficiency and quality safety level, and is favorable for promoting the deep integration of the building industry and the information industrialization, cultivating new kinetic energy of new industry and promoting the excess capacity of chemical solution. The assembly type structure is adopted, standardized design, factory production, even product production, assembly construction, integrated decoration, informatization management and intelligent application can be realized, the construction efficiency is effectively improved, the cost is reduced, energy and resources are saved, construction waste and adverse effects on the environment are reduced, the technical level and the engineering quality are improved, and the transformation and the upgrade of the construction industry are promoted.

Building industrialization is the development direction of future building industry, and assembly type buildings are the hot spot of research and development practice of institutions of various departments and colleges of medicine and building enterprises in recent years, various prefabricated component forms and types are abundant, and novel, high-quality and different-performance prefabricated component products are developed rapidly and widely applied, but because the foundation of China in the assembly type building field is weak and late, a lot of defects exist in the field, for example, 1, factory production of prefabricated components is not production, so that the component production is actually changed into customized production rather than batch production, the component production cost is increased, and the flexibility is reduced. The customized production also makes the molds for producing the components expensive. Because the method belongs to customized production, the component processing production of a factory needs to be carried out along with project schedule rather than production capacity of the factory, wave crest and wave trough changes of the production capacity are easily generated, the production efficiency of the factory is actually reduced, and the production cost is actually increased; 2. the large size of the prefabricated components generally increases the cost and difficulty of the components in terms of production, storage, transportation, installation, etc.; 3. the prefabricated beam column has higher requirements on precision in production, higher requirements on construction enterprises in installation, difficulty in effective quality acceptance and the like; 4. the assembly type building has higher requirements on construction management and personnel quality, increases the cost and simultaneously causes the defects of qualified personnel.

In the grouting sleeve method construction process generally adopted by the assembly type structure of the existing frame building, the prefabricated parts of the building need to plug the reserved extending reinforcing steel bars on the prefabricated parts into the reserved holes corresponding to the positions and the apertures of the prefabricated parts during assembly construction, and then high-strength cement is poured into the connecting positions to fixedly connect the prefabricated parts and the prefabricated parts.

However, in the actual assembly process, the reinforcing steel bars extending out of the prefabricated parts are easy to bend in the production, transportation and installation processes, and the extending-out reinforcing steel bars have verticality deviation, so that the inserting is often not in place in the process of inserting into the preformed holes of the corresponding prefabricated parts, and the problem of difficult assembly is caused. Even after the high-strength cement is inserted in place, in the process of pouring the high-strength cement into the sleeve, whether the high-strength cement is poured in place is difficult to recheck and judge so as to stably assemble the high-strength cement and the sleeve, and uncertain potential safety hazards exist to influence the quality of an assembled building. In addition, in the construction process, the technology of constructors and the responsibility center are very high, but the mode of relying on the responsibility center of people rather than rules and regulations can cause great hidden dangers, the cases that the steel bar is difficult to be vertically pulled because the bending degree of the extending steel bar is too large and the construction team cuts off the steel bar privately occur in the actual operation, and although the construction is finished, the huge safety quality problem is endless.

In conclusion, the building frame structure in the prior art has the problems of high assembly difficulty, difficulty in effective rechecking of quality, high requirement on operators and the like during assembly.

The provided column connecting node adopts an improved mode of connecting the column 5 and the cross beam 4, and adopts the column sleeve 2, the cross beam 4, the column 5 and the column-beam connecting piece 3 as basic connecting prefabricated parts.

The inner cavity of the column cap 6 can be relatively bound with structures such as column stirrups at the end part of the column 5 through the fourth connecting piece 62, and poured together, so that the column cap 6 is firstly fixed on the end part of the column 5, at the moment, the column cap 6 is equivalent to a mold for prefabricating the end part of the column 5, after concrete is poured into the inner cavity of the column cap 6, the end part structure of the column 5 can be formed after the concrete is solidified and molded, and the column cap 6 is fixed on the column 5 and is integrated with the column 5 to bear force together; the bore of the post sleeve 2 can then be used to mate with an adjacent cap 6 on an adjacent post 5 and to secure the adjacent cap 6 relative to the post sleeve 2, thereby longitudinally connecting the adjacent posts 5 together using the post sleeve 2. The inner cavity of the beam cap 1 can be relatively bound and poured together through structures such as the first connecting piece 13 and the beam stirrup at the end part of the beam 4, at the moment, the beam cap 1 is equivalent to a mold for prefabricating the end part of the beam 4, and after concrete is poured into the inner cavity of the beam cap 1, the end part structure of the beam 4 can be formed through concrete molding, so that the beam cap 1 is fixed on the beam 4. At this time, the column sleeves 2 and the beam caps 1 are oppositely connected, so that the columns 5 and the beams 4 can be stably assembled together to form the assembled building frame structure.

As shown in fig. 3 and 4, a first insertion structure 21 is provided on the pillar sleeve 2, and as shown in fig. 8 and 9, a second insertion structure 11 that is inserted into and matched with the first insertion structure 21 is provided on the spar cap 1, and the first insertion structure 21 and the second insertion structure 11 can be inserted into each other to connect or position the pillar sleeve 2 and the spar cap 1.

The bottom end face of the spar cap 1 is the end face where the second plug structure 11 is arranged, i.e. the end face opposite to the opening of the spar cap 1, as shown in fig. 8 and 9 in combination with fig. 10 and 11. It should be noted that the first insertion structure 21 can be a structure formed on the pillar sleeve 2, or a structure detachably connected to the pillar sleeve 2; the first plug structure 21 can be a structure recessed in the pillar sleeve 2 or a structure protruding out of the pillar sleeve 2, and the shape of the first plug structure 21 can be a common geometric figure or any irregular shape, and those skilled in the art can design the specific structure of the first plug structure 21 as required. Similarly, the specific structure of the second inserting structure 11 is consistent with the design idea of the first inserting structure 21 in the specific structure, as long as the two can be inserted relatively, so as to connect or position the column sleeve 2 and the beam cap 1.

With continued reference to fig. 12 and 13, the column-to-beam connector 3 includes a first connector 31 and a second connector 32 connected to each other, the column-to-beam connector 3 is fitted between the column sleeve 2 and the spar cap 1, the first connector 31 can be connected to the spar cap 1, and the second connector 32 can be connected to the column sleeve 2, so that a secondary connection can be formed between the column sleeve 2 and the spar cap 1 via the column-to-beam connector 3. It should be noted that, during assembly, the specific operation sequence is not limited, and those skilled in the art can select a reasonable assembly sequence according to actual situations. Meanwhile, the specific connection form of the first connection part 31 and the second connection part 32 of the column-beam connection member 3 with the spar cap 1 and the column sleeve 2 is not limited, and the connection form of the two parts can include threaded connection, hanging connection, riveting connection, bonding connection and any other connection form.

Therefore, the column sleeve 2 and the beam cap 1 can be stably assembled by connecting or positioning the column sleeve 2 and the beam cap 1 through the first plug structure 21 and the second plug structure 11 and forming secondary connection on the column sleeve 2 and the beam cap 1 through the column-beam connecting piece 3, so that the column 5 and the beam 4 connected in the column sleeve 2 and the beam cap 1 can be stably assembled. Moreover, the assembly mode can avoid the problem of difficult steel bar splicing in the prior art, and can also solve the problem that the assembly quality is influenced by uncertain cement pouring effect and the like at the connecting position of the column 5 and the beam 4. The assembling structure formed by the column connecting nodes is simple to assemble, the assembling effect can be controlled, and the assembling quality is guaranteed.

Further, a first hole group 12 is arranged on the side wall of the beam cap 1, and a first connecting piece 13 is fixedly inserted into a through hole of the first hole group 12; one end of the first connecting piece 13 inserted into the first hole group 12 has a first limiting portion 131 for limiting connection with the beam 4.

As shown in fig. 10 and 11, a connection structure of the first hole group 12 and the first connecting member 13 is adopted for the connection of the spar cap 1 and the cross beam 4. The first connecting piece 13 is further provided with a first limiting portion 131, when the beam cap 1 and the beam 4 are assembled, the first connecting piece 13 is inserted into the through hole of the first hole group 12, and the first connecting piece 13 can be fixedly connected with the beam cap 1 after being inserted into the through hole of the first hole group 12. At this moment, the first limiting portion 131 is inserted into the through hole inner side of the beam cap 1 of the first hole group 12 and can be bound and limited by structures such as beam stirrups of the beam 4 inserted into the inner cavity of the beam cap 1, and then the structures such as the beam stirrups of the beam 4 and the first connecting pieces 13 in the beam cap 1 are poured into a whole by adopting a concrete pouring mode, so that the beam 4 cannot be reversely separated from the inner cavity of the beam cap. Here, the side wall of the spar cap 1 refers to a wall surface provided with the first hole group 12, that is, as shown in fig. 8 to 11 in combination, positions of other four wall surfaces except for the opening and bottom end surface of the spar cap 1.

It should be noted that, in the process that the first connecting member 13 is inserted into the first hole group 12 and fixedly connected to the cap beam 1, the cap beam 1 may be used as a prefabricated mold for prefabricating the end portion of the beam 4, that is, the first connecting member 13 is directly installed and connected in the cap beam 1 in the process of prefabricating the cap beam 1, the first connecting member 13 is installed in the cap beam 1, prefabricated materials such as concrete are poured into the inner cavity of the cap beam 1, a beam having the end portion structure of the beam 4 can be formed after the concrete is formed, and the first connecting member 13 is directly fixed in the cap beam 1 after the cap beam is formed. In addition, as to the number and arrangement manner of the first hole group 12 and the first connecting piece 13, the number may be determined according to the design and arranged uniformly, or arranged only at the position where the force is much, and the shape may be rectangular, circular, etc., which is not limited herein.

For the limiting form between the first limiting portion 131 and the cross beam 4, a relative hanging structure, a fixed clamping structure or a limiting form like interference fit between hole shafts can be adopted, and a person skilled in the art can select a reasonable limiting form by himself to limit the cross beam 4 from being separated from the inner cavity of the beam cap.

Preferably, the first position-limiting portion 131 includes a first hook to be able to be hooked with the beam stirrup 43 of the cross beam 4; and/or the first limiting part and the beam stirrup of the cross beam are bound together. That is, the first limiting portion may be hooked with the beam stirrup 43 of the beam 4 in a manner of a first hook, or may be bound with the beam stirrup 43 of the beam 4 in a manner of binding; meanwhile, two modes can be comprehensively adopted, and after the first limiting part is hung and connected with the beam stirrup 43 of the cross beam 4 in a structural mode of a first hook, the first limiting part is tied and connected with the beam stirrup 43 of the cross beam 4 in a binding mode.

For example, the first limiting portion 131 is configured by a first hook, the first hook can hook the beam stirrup 43 inside the beam 4 when the beam cap is assembled with the beam 4, and when the first hook hooks the beam stirrup 43, the beam 4 can be limited from moving in a direction away from the inner cavity of the beam cap, so that the assembly stability between the beam cap and the beam 4 is ensured. In the same way, the same effect can be achieved by binding.

For example, when the cross member 4 is in a manner that the beam reinforcement cage 41 is coupled with the beam concrete structure 44, as shown in fig. 1 to 23, the first hook of the first coupling member 13 assembled to the cap 1 may be hooked with the beam stirrup 43 of the beam reinforcement cage 41 in the cross member 4 first. And then pouring concrete into the inner cavity of the beam cap 1, using the beam cap 1 as a mold to form a beam concrete structure 44 through the inner cavity of the beam cap 1, and forming the beam concrete structure 44 between the inner cavity of the beam cap 1 and the beam reinforcement cage 41, so that the relative pouring connection between the first hook and the beam stirrup 43 of the cross beam 4 is realized.

For the connection between the column beam connector 3 and the beam cap, since the first connector 13 is disposed on the beam cap, the column beam connector 3 and the beam cap can be assembled and connected by connecting the first connector 13 and the second connector 312. In order to enable the first and second connectors 13 and 312 to be connected to each other when the beam cap and the column-beam connector 3 are assembled, the arrangement of the second hole group 311 needs to correspond to the arrangement of the first hole group 12. Therefore, when the second connecting piece 312 is inserted into the through hole of the second hole set 311, the second connecting piece 312 can correspond to the first connecting piece 13 in position and form relative connection.

Preferably, the through hole of the second hole group 311 is a threaded hole, the second connecting member 312 is provided with an external thread, and the second connecting member 312 is in threaded connection with the threaded hole of the second hole group 311; the second connector 312 is screwed to the first connector 13. The connection structure can be formed more stably and conveniently by a threaded connection mode. Meanwhile, the second connecting piece can be oppositely inserted and assembled with the through hole of the second hole group, and the second connecting piece is in threaded connection with the first connecting piece.
