An assembled building column, beam, and plate structure and construction method thereof

Abstract

The present invention discloses an assembled building column, beam, and plate structure, including a column, a main beam, a secondary beam, and a plate body. The surfaces of both ends of the column are provided with a column center reserved hole, the inner side of the column center reserved hole is provided with a shear rod, the surfaces of both ends of the column are fixedly connected with four-corner brackets, the outer sides of both ends of the column are provided with a column wedge, the middle of the two side surfaces of the main beam are fixedly connected with the outer edge of the main beam, and the outer surfaces of both sides of the main beam at the top of the outer edge of the main beam are provided with beam pre-embedded joint steel bars; the structural design embodies the design concept of strong column hinges. When an earthquake occurs, the bolts between the columns and the weak brackets form a hinge structure, and the column is allowed to have a larger swing amplitude. In the limit state, the brackets are destroyed first, and the shear rods in the center of the column take effect. At the same time, the weak connection of the beam and the plate to the column forms a buffering constraint force, which is conducive to releasing the earthquake power. In addition, the joints of the main components are dry connections or wedge connections, and no template is required, which is convenient for rapid assembly and construction.

Description

Technical Field

[0001] The present invention belongs to the technical field of assembled building structures, and in particular relates to an assembled building column, beam, and plate structure and a construction method thereof. Background Art

[0002] In traditional building structures, the steel bars of columns and beams are designed to cross each other, and concrete is poured to form an overall structure. The characteristics of the damage caused by the Wenchuan earthquake show that the intersection of the bottom of the beam and the column is the main area of ​​damage, and the fracture of the column is the main cause of the collapse of the house. In addition, traditional construction technology mainly uses on-site casting operations, and all materials need to be transported to the construction site, occupying a large amount of social road traffic resources, causing noise and dust pollution.

[0003] Prefabricated buildings are an emerging industry in my country and are in a gradual development stage in terms of structural technology. Most prefabricated buildings continue the traditional design concept and use the wet connection method of column and beam reinforcement joints at the joints, resulting in the prefabricated structure not taking into account the impact of earthquakes on structural damage. In terms of construction technology, since the structure is the same as the traditional technology, the division of labor between wet connection and prefabrication is not thorough, resulting in no reduction in on-site construction procedures. The cost of prefabricated buildings is higher than that of cast-in-place construction. For this reason, we propose a prefabricated building column, beam, and slab structure and its construction method. Summary of the invention

[0004] The object of the present invention is to provide a prefabricated building column, beam, and plate structure and a construction method thereof to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an assembled building column, beam, and plate structure, comprising a column, a main beam, a secondary beam, and a plate body, wherein the surfaces at both ends of the column are provided with a column center reserved hole, the inner side of the column center reserved hole is provided with a shear rod, the surfaces at both ends of the column are fixedly connected with four-corner brackets, the outer sides of both ends of the column are provided with column wedges, the middle parts of the surfaces at both sides of the main beam are fixedly connected with the outer edges of the main beams, the outer surfaces at the top ends of the outer edges of the main beams on both sides of the main beams are provided with beam pre-embedded joint steel bars, the middle parts of the outer sides of the outer edges of the two main beams are provided with secondary beam connection wedges, and the bottom ends of the main beams are fixedly connected with A beam wedge is connected, the bottom ends of the two side surfaces of the secondary beam are fixedly connected to the outer edge of the secondary beam, the top ends of the two side surfaces of the secondary beam are fixedly connected to the secondary beam joint steel bars, the two side surfaces of the bottom end of the secondary beam are fixedly connected to secondary beam wedges, the top ends of the two side surfaces of the plate body are provided with plate joint steel bars, the bottom ends of the two side surfaces of the plate body are fixedly connected to the outer edge of the plate, embedded nuts are provided on the inner sides of the four corners of the top end of the four-corner corbels, the outer sides of the embedded nuts are longitudinally overlapped with overlapping steel bars, and the outer sides of the overlapping steel bars are transversely overlapped with the main reinforcement of the column.

[0006] Preferably, the depth of the reserved hole in the center of the column is half of the depth of the shear rod.

[0007] Preferably, the plate body has an outer shape of a two-layer rectangle, and the upper rectangle is smaller than the lower rectangle.

[0008] A construction method for assembled building columns, beams and slabs:

[0009] Step 1: Lay out and measure the installation position of the positioning column on the ground, cast the embedded nuts in situ, and cast the reserved hole in the center of the column in situ. The hole diameter is slightly larger than the diameter of the shear rod;

[0010] Step 2: Apply epoxy resin adhesive inside the ground and column shear rods and on the end faces of the columns, place the shear rods into the reserved holes in the center of the ground columns, and then hoist the prefabricated columns into the shear rods, adjust the positions so that the four-corner brackets are aligned, insert the connecting bolts and elastic washers, and tighten the bolts.

[0011] Step 3: Lift the column into the column wedge opening;

[0012] Step 4: hoist the secondary beam into the secondary beam connecting wedge of the main beam;

[0013] Step 5: Hoist the plate body into the beam, weld the beam and embed the joint steel bars;

[0014] Step 6: Pour concrete into the end face of the beam and the joint of the steel bars to seal the joints;

[0015] Step 7: Install the upper columns, beams and slabs in sequence.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The structural design reflects the design concept of strong column hinges. When an earthquake occurs, the bolts between the columns and the weak brackets form a hinge structure, allowing the columns to have a larger swing amplitude. In the limit state, the brackets are destroyed first, and the shear rods in the center of the column take effect. At the same time, the weak connection of beams and plates to the columns forms a buffering constraint force, which is conducive to releasing earthquake power. In addition, the joints of the main components are dry connections or wedge connections, which do not require templates and are easy to assemble and construct quickly.
