Description

Technical Field

[0001] The utility model relates to a connection structure of prefabricated beams and columns, belonging to the technical field of building construction. Background Art

[0002] The use of precast beams and precast columns can speed up the construction progress of the ground floor. After the precast beams and precast columns are connected, it is sometimes necessary to pour a cast-in-place layer to improve the integrity.

[0003] The prior art is shown in Chinese patent announcement number CN213897485U. The cast-in-place concrete layer is cast on a precast concrete square beam, and the cast-in-place concrete square column is penetrated by the longitudinal reinforcement at the top of the beam in the concrete layer. Although the longitudinal reinforcement at the top of the beam in the horizontal state can resist and disperse the left and right loads of the concrete layer, there is a problem that the front and rear loads of the concrete layer cannot be dispersed. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a connection structure of prefabricated beams and columns.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a prefabricated beam-column connection structure, comprising:

[0007] Precast columns;

[0008] Precast beams distributed on the sides of the middle of the precast columns;

[0009] The precast beam contains precast beam bottom reinforcement, precast beam connecting reinforcement and precast beam hugging reinforcement. A plurality of spaced precast beam hugging reinforcements surround the precast beam bottom reinforcement and the precast beam connecting reinforcement. Most of the precast beam hugging reinforcements in the hugging state are located inside the precast beam, and a small portion of the precast beam hugging reinforcements in the hugging state are exposed outside the top of the precast beam.

[0010] It also includes a cast-in-place layer formed by cast-in-place casting; the cast-in-place layer has cast-in-place layer horizontal steel bars, and a small part of the precast beam reinforcing bars exposed on the top of the precast beam surrounds the cast-in-place layer horizontal steel bars.

[0011] The prefabricated column has a plurality of prefabricated column vertical reinforcements distributed at intervals in the vertical direction, a plurality of prefabricated column embracing reinforcements distributed at intervals in the horizontal direction between the prefabricated column vertical reinforcements, and a prefabricated column connecting reinforcement in the middle of the prefabricated column vertical reinforcements.

[0012] The bottom reinforcement of the precast beam is connected by a reinforcement anchor plate.

[0013] The prefabricated beam connecting ribs are connected to the prefabricated column connecting ribs through mechanical sleeves.

[0014] The cast-in-place layer forms limiting protrusions in the prefabricated beams and prefabricated columns.

[0015] The prefabricated columns are connected to the cast-in-place layer through a mortar layer.

[0016] The beneficial effects of the utility model are as follows: the horizontal steel bars of the cast-in-place layer can disperse the left and right loads on the cast-in-place layer, and the multiple spaced precast beam reinforcing bars can disperse the front and rear loads when the cast-in-place layer is subjected to the front and rear loads. The front and rear load dispersion energy can be transmitted to the precast beams through the precast beam reinforcing bars for diffusion and distribution, thus solving the problem that the longitudinal bars at the top of the beam in a horizontal state can resist and disperse the left and right loads on the concrete layer, but the front and rear loads on the concrete layer cannot be dispersed.

DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0020] like Figure 1 shown.

[0021] A prefabricated beam-column connection structure of the present application comprises:

[0022] The precast column 1 has an upper and lower part. The precast column 1 has a plurality of precast column vertical reinforcements 11 distributed vertically at intervals. A plurality of precast column holding reinforcements 12 distributed horizontally at intervals are arranged between the precast column vertical reinforcements 11. A precast column connecting reinforcement 13 is arranged in the middle of the precast column vertical reinforcements 11.

[0023] The precast beams 2 are distributed on both sides of the middle of the precast column 1, and the precast beam bottom reinforcement 21, the precast beam connecting reinforcement 22 and the precast beam hugging reinforcement 23 are arranged in the precast beam 2. A plurality of spaced precast beam hugging reinforcements 23 embrace the precast beam bottom reinforcement 21 and the precast beam connecting reinforcement 22; most of the precast beam hugging reinforcement 23 in the hugging state are in the precast beam 2, and a small part of the precast beam hugging reinforcement 23 in the hugging state is exposed outside the top of the precast beam 2.

[0024] The precast beam bottom reinforcement 21 of the precast beams 2 on both sides of the middle of the precast column 1 is connected through a steel bar anchor plate 24. The precast beam connecting reinforcement 22 is connected to the precast column connecting reinforcement 13 through a mechanical sleeve 3.

[0025] It also includes a cast-in-place layer 5 formed by cast-in-place casting, and the cast-in-place layer 5 forms a limiting protrusion 3 in the precast beam 2 and the precast column 1. The limiting protrusion 3 of the precast beam 2 of the cast-in-place layer 5 limits the upper and lower disturbance displacement, and the limiting protrusion 3 of the precast column 1 of the cast-in-place layer 5 limits the left and right disturbance displacement; the cast-in-place layer 5 has a cast-in-place layer horizontal steel bar 51, and a small part of the precast beam reinforcement 23 exposed on the top of the precast beam 2 embraces the cast-in-place layer horizontal steel bar 51; the cast-in-place layer horizontal steel bar 51 disperses the left and right loads, and a plurality of spaced precast beam reinforcements 23 can disperse the cast-in-place layer 5 when it is subjected to front and rear loads. The front and rear load dispersion energy can be transmitted to the precast beam 2 through the precast beam reinforcement 23 to diffuse and share, which solves the problem that the longitudinal reinforcement on the top of the beam in a horizontal state can resist the left and right loads of the concrete layer for dispersion, while the front and rear loads of the concrete layer cannot be dispersed.

[0026] The lower part of the prefabricated column 1 is first formed, and the bottom of the upper part of the prefabricated column 1 is connected to the cast-in-place layer 5 through the mortar layer 4.

[0027] The up, down, left, and right directions of the present application are merely defined with reference to the drawings and are not actual direction limitations.
