Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated beams, in particular to a prefabricated assembled reinforced concrete beam reinforcement structure. Background Art

[0002] In the existing building construction, in order to improve the construction efficiency, many existing concrete parts are prefabricated and then assembled on site, which can improve the construction efficiency and shorten the gas supply. Among them, prefabricated beams are prefabricated in the factory and then transported to the construction site for installation and fixation according to the design requirements.

[0003] When assembling existing precast beams, a bracket is used to support the beam body, and its end is positioned and placed with the upper end of the column, and then the column and the intersection with the precast beam are connected by post-cast concrete. Intersecting steel bars are set between the column and the precast beam, but only post-cast concrete is used to connect the column and the precast beam. Due to the water-cement ratio, environment, water evaporation, casting problems and unreasonable maintenance when the post-cast concrete and the precast concrete are actually connected, the connection is very likely to crack after a long time, thereby reducing the connection strength between the beams and between the beams and the columns. In order to improve the connection strength of the precast beams, a prefabricated assembled reinforced concrete beam reinforcement structure is provided. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The following will be combined Figure 1-Figure 3 A prefabricated assembled reinforced concrete beam reinforcement structure according to an embodiment of the utility model is described in detail.

[0018] Example:

[0019] The utility model provides a prefabricated reinforced concrete beam reinforcement structure, referring to Figure 1-Figure 3 As shown, it includes a precast beam 1 and a column 17. Two connecting members 2 are pre-buried at both ends of the precast beam 1. An inner reinforcement plate 6 is connected between the connecting members 2 at both ends of two adjacent precast beams 1. This structure connects the ends of adjacent precast beams 1 through the connecting members 2. The precast beam 1 on a column 17 is connected into a whole by using the connecting members 2, so that the installation position of the precast beam 1 can be positioned and the connection strength between the beams can be improved.

[0020] refer to Figure 2 As shown, two anchor rods 14 are fixedly connected to the mounting surfaces on both sides of the inner reinforcement plate 6. This structure uses the anchor rods 14 to be riveted with the precast beam 1 and the column 17 by post-cast concrete, thereby connecting the inner reinforcement plate 6 with the column 17 and improving the tensile strength of the inner reinforcement plate 6.

[0021] refer to Figure 2 As shown, connectors 4 are embedded on both sides of the front and rear side walls and the bottom surface of the precast beam 1, and side reinforcement plates 7 are connected between the connectors 4 on the front and rear side walls of two adjacent precast beams 1. In this structure, the side walls of adjacent precast beams 1 are connected to the side reinforcement plates 7 through connectors 4, thereby reinforcing the outer corner connections of adjacent precast beams 1, and cooperate with the inner reinforcement plates 6 to form a double-track reinforcement structure, further improving the integrity and connection strength between the precast beams 1.

[0022] refer to Figure 1 As shown, connector three 5 is pre-embedded on the four upper side walls of the column 17, and a bottom reinforcement plate 8 is connected between connector two 4 at the bottom of the precast beam 1 and connector two 4 on the upper side wall of the column 17. This structure connects a bottom reinforcement plate 8 between connector three 5 and connector two 4 at the bottom of the precast beam 1, thereby supporting and reinforcing the external connection between the column 17 and the precast beam 1, thereby improving the integrity of the precast beam 1 and the column 1, and improving the bearing capacity of the connection between the precast beam 1 and the column 17.

[0023] refer to Figure 1-Figure 3 As shown, the structures of the connector 1 2, the connector 2 4 and the connector 3 5 are the same, and all include a mounting plate 9. Four anchor rods 10 are fixedly connected to the bottom of the mounting plate 9. Four end corners of the mounting plate 9 are fixedly connected to fixing seats 11, and threaded holes 12 are provided on the fixing seats 11. With this structure, the mounting plate 9 is stably embedded in the prefabricated beam 1 and the column 17 through the anchor rods 10, and the threaded holes 12 on the fixing seats 11 facilitate the fixing of the mounting plate 9 and the connectors through threaded connection.

[0024] refer to Figure 1-Figure 3As shown, the inner reinforcement plate 6, the side reinforcement plate 7 and the bottom reinforcement plate 8 have the same structure, which is an L-shaped structure, and four mounting holes 13 are provided on the mounting surfaces on both sides. This L-shaped structural reinforcement plate is convenient for fixing between adjacent precast beams 1 and at the connection between the precast beam 1 and the column 17, thereby improving the integrity between the embedded beams 1 and the integrity between the precast beam 1 and the main body 17.

[0025] refer to Figure 2 and Figure 3 As shown, anchor rod 10 and anchor rod 2 14 have the same structure and both include a rod body 15. A baffle 16 is welded to the outer wall of the rod body 15. In this structure, the rod body 15 and the baffle 16 are embedded in the embedded beam 1 and the column 17. The baffle 16 can prevent the rod body 15 from being pulled and slipped, thereby improving the embedded connection strength.

[0026] The implementation principle of a prefabricated reinforced concrete beam reinforcement structure of the embodiment of the present application is as follows: the ends of adjacent prefabricated beams 1 are connected by a connector 1 2, and the prefabricated beams 1 on a column 17 are connected into a whole by using the connector 1 2, so that the installation position of the prefabricated beams 1 can be positioned, and the connection strength between the beams can be improved;

[0027] The side walls of adjacent precast beams 1 are connected by connecting members 4 to the side reinforcing plates 7, thereby reinforcing the outer corner connections of adjacent precast beams 1, and forming a double-track reinforcement structure with the inner reinforcing plates 6, further improving the integrity and connection strength between the precast beams 1;

[0028] A bottom reinforcement plate 8 is connected between the connecting piece 3 5 on the column 17 and the connecting piece 2 4 at the bottom of the precast beam 1, so as to provide support and reinforcement at the outer corner connection between the column 17 and the precast beam 1, thereby improving the integrity of the precast beam 1 and the column 1, and improving the bearing capacity of the connection between the precast beam 1 and the column 17.
