Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and specifically relates to a novel assembled reinforced concrete frame structure. Background Art

[0002] At present, the prefabricated building system is being vigorously promoted to realize the transformation and upgrading of the modernization of the construction industry. Sleeve grouting connection and post-poured concrete connection are common connection methods in prefabricated concrete structures. Sleeve grouting connection has reliable connection strength and good seismic performance, but it has strict requirements on the quality of grouting materials and construction technology.

[0003] The new prefabricated reinforced concrete frame structure is mainly composed of main structural prefabricated components such as precast concrete columns, new steel beams and precast composite floor slabs, which are connected together to form a whole and bear vertical and horizontal loads. The connection nodes include nodes where precast columns are connected by grouting sleeves and nodes formed by precast columns and steel beams through a new dry connection method.

[0004] However, the existing structure cannot connect the prefabricated columns firmly and stably to the base when connecting the prefabricated columns, and cannot ensure the overall strength of the prefabricated columns when pouring between the prefabricated columns, and cannot ensure the stress degree of the connection. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a novel assembled reinforced concrete frame structure.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a novel assembled reinforced concrete frame structure, comprising a structural finished surface, a connection mechanism is fixed to the top of the structural finished surface, a prefabricated column is arranged inside the connection mechanism, a cantilever section is extended outward from the top of the prefabricated column, a pouring mechanism is arranged at the top of the prefabricated column, a prefabricated concrete beam is installed outside the prefabricated column, a post-pouring mechanism is arranged outside the prefabricated concrete beam, and a second cement pouring port is arranged outside the prefabricated column;

The connecting outer sleeve is fixed at the top of the structural finished surface. The connecting inner sleeve is arranged inside the connecting outer sleeve. The first through hole is opened inside the connecting outer sleeve. The second through hole is opened inside the connecting inner sleeve. The third through hole is opened inside the connecting inner sleeve. A blocking plate is fixed inside the connecting inner sleeve. A first steel bar is fixed inside the connecting inner sleeve.

The larger the space occupied by the plant cement during solidification, the more it can ensure the strength and seismic resistance of the connection.

[0009] Preferably, the second through holes and the third through holes are symmetrically distributed about the central axis of the baffle plate, and a plurality of groups of the second through holes and the third through holes are arranged, and the second through holes and the third through holes are symmetrically distributed about the central axis of the connecting outer sleeve, further expanding the space occupied by cement.

[0010] Preferably, the first steel bars are provided in a plurality of groups, and the first steel bars are symmetrically distributed about the central axis of the connecting inner sleeve, so that the first steel bars further improve the overall strength of the cement after the cement solidifies.

[0011] Preferably, the pouring mechanism includes a first cement pouring port, a second steel bar and a third steel bar. The first cement pouring port is opened at the top of the prefabricated column, the second steel bar is fixed inside the cantilever section of the prefabricated column, and the third steel bar is fixed at the top inside the prefabricated column.

[0013] Preferably, the third steel bars are arranged in several groups, and the third steel bars are distributed at equal intervals about the central axis of the precast column. The third steel bars and the second steel bars are in a cross shape, so that after the cement solidifies, the second steel bars and the third steel bars further improve the overall strength of the cement.

[0014] Preferably, the post-casting mechanism includes a first cement post-casting trough, a first connecting rib and a first cement post-casting port, the first cement post-casting trough is arranged outside the cantilever section of the precast column, a first connecting rib is fixed inside the first cement post-casting trough, a first cement post-casting port is arranged at the top of the cantilever section of the precast column, a second cement post-casting trough is arranged outside the precast concrete beam, a second connecting rib is fixed inside the second cement post-casting trough, a second cement post-casting port is arranged at the top of the precast concrete beam, and the two groups of precast blocks are connected by pouring high-performance cement-based materials to ensure the strength of the connection.

[0015] Preferably, the shape of the first cement post-casting groove is the same as that of the second cement post-casting groove, and a plurality of groups of the first connecting ribs are provided, and the first connecting ribs are distributed at equal intervals about the central axis of the first cement post-casting groove.

[0018] The present invention cooperates with structures such as a connecting outer sleeve, a connecting inner sleeve, and a first through hole, and can hoist the prefabricated column as a whole on the top of the connecting outer sleeve, align the connecting inner sleeve at the bottom of the prefabricated column with the connecting outer sleeve, insert and install it, and pour cement into the interior of the prefabricated column through the second cement pouring port or the first cement pouring port, add "nano platelets" extracted from carrots and other root vegetables and bamboo chips to the cement, thereby improving the seismic resistance and compressive strength of the building, and after the plant cement is poured into the interior of the prefabricated column, it fills the interior of the prefabricated column, the connecting outer sleeve and the connecting inner sleeve. After solidification, the solidified cement connects the connecting outer sleeve, the connecting inner sleeve and the prefabricated column through its own shape, thereby achieving the purpose of facilitating the connection of the prefabricated column with the base.

[0019] The present invention arranges the coordination of the first cement pouring port, the second steel bar, the third steel bar and other structures, so that the middle section of the prefabricated block pours the plant cement into the interior of the group of prefabricated columns through the first cement pouring port, and by installing staggered second steel bars and third steel bars inside the prefabricated columns, the plant cement can have stronger earthquake resistance and compression resistance when solidified. Since the cement is poured later, the prefabricated columns are lighter and more convenient to transport, thereby achieving the purpose of facilitating the connection of the middle section of the prefabricated columns with the base and improving the transportation efficiency and overall strength of the prefabricated columns.

[0020] The present invention arranges the first cement post-casting groove, the first connecting rib, the first cement post-casting mouth and other structures to cooperate, so that the device can assemble the precast column cantilever section with the precast concrete beam, the first cement post-casting mouth and the second cement post-casting mouth are connected to form a cement inlet, the first cement post-casting groove and the second cement post-casting groove form a cavity, and high-performance cement-based material is poured into the cement inlet. After solidification, since the first connecting rib and the first cement post-casting mouth are staggered, the solidified cement connects the first connecting rib and the second connecting rib together, and then connects the precast column cantilever section and the precast concrete beam, so as to achieve the purpose of facilitating the connection between precast blocks.
