Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled building beam-column connection point reinforcement structure. Background Art

[0002] In modern prefabricated buildings, the most important supporting relationship is the beam-column structure of the building. At the current stage, the assembly and construction of the beam-column structure mainly adopts a steel connection cage set at the top of the column, and then the end of the assembly beam is overlapped on the head end of the column, and the joint position of the beam and column is cast. However, in actual use, the support of the assembly beam with this connection method is mainly connected by the head end steel bar and the concrete block at the joint position, and the overlapping part provides support force. Since the assembly beam and the column are not an integrated structure, when used for a long time, its connection position is prone to lateral dislocation due to vibration, which leads to the problem of unfavorable support. In view of this, in-depth research on the above problems has led to the creation of this case. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0019] See also Figure 1-3 The utility model provides an implementation scheme: in the modern prefabricated building construction process, the connection points of the beams and columns of the prefabricated buildings are mainly connected by lap connection, and the connection is carried out in combination with pouring. However, due to the lack of a horizontal and transverse limiting mechanism, the beam-column connection position of the prefabricated building has poor resistance to transverse vibration. Therefore, the present application discloses a reinforcement structure for the connection points of the beams and columns of the prefabricated building. The building uses a supporting column 1 as a supporting foundation. The supporting column 1 is a rectangular column of a concrete structure, and a steel cage is built in as a reinforcement. A plurality of supporting steel bars 2 arranged in a rectangular array are extended from the top of the supporting column 1. The plurality of supporting steel bars 2 and the plurality of connecting steel bars 12 at the head end of the prefabricated cross beam 3 are arranged in a staggered manner. After the prefabricated cross beam 3 is hoisted into place, the connecting steel bars 12 and the supporting steel bars 2 should be arranged in a staggered manner. Then, in combination with pouring, a concrete block 6 is cast at the joint position of the supporting column 1 and the prefabricated cross beam 3 to form the supporting column 1 and the prefabricated cross beam 3.

[0020] According to the instruction manual Figure 1-3 It can be seen that a socket 4 of a rectangular structure is provided on one side of the top of the supporting column 1 below the assembled cross beam 3, and a socket block 5 corresponding to the socket 4 is provided at the bottom of the assembled cross beam 3. The socket block 5 is inserted into the socket 4, and the assembled cross beam 3 and the supporting column 1 are limited and connected by inserting the socket block 5 into the socket 4. At the same time, the horizontal position of the assembled cross beam 3 is limited by the socket block 5 in the socket 4, so that when subjected to vibration, the problem of lateral displacement of the assembled cross beam 3 is avoided, thereby improving the horizontal seismic resistance;

[0021] According to the instruction manual Figure 1-3 It can be seen that a number of first bolt connection seats 7 are evenly buried on the socket block 5, a number of second bolt connection seats 8 are buried on one side of the support column 1, and a reinforcing angle seat 9 is installed at the right-angle turning point between the socket block 5 and the support column 1. The reinforcing angle seat 9 is a plate of a right-angled triangle structure, and the right-angled sides of the right-angled triangle are respectively attached to the socket block 5 and the support column 1. A number of connecting holes 10 corresponding to the number of first bolt connection seats 7 and the number of second bolt connection seats 8 are respectively opened on the right-angled sides on both sides of the reinforcing angle seat 9, and connecting bolts 11 are penetrated in the connecting holes 10 to connect with the first bolt connection seat 7 or the second bolt connection seat 8;

[0022] In the specific implementation process, the first bolt connection seat 7 and the second bolt connection seat 8 buried in the socket block 5 and the supporting column 1 are used as the connection points for connecting the reinforced angle seat 9. Since the first bolt connection seat 7 and the second bolt connection seat 8 can be buried during prefabrication, it not only improves the construction efficiency, but also improves the connection stability of the connection point. The right-angle position of the supporting column 1 and the assembled cross beam 3 is supported and strengthened by the reinforced angle seat 9, and the connecting bolts 11 pass through the connecting holes 10 to connect with the first bolt connection seat 7 and the second bolt connection seat 8 respectively, so as to fix the position of the reinforced angle seat 9.

[0023] As a preferred solution, further, a wrapping sleeve is provided outside the socket block 5 corresponding to the reinforced angle seat 9, which wraps around the outside of the socket block 5, wraps and limits the horizontal outside of the socket block 5, and further improves the earthquake resistance in the horizontal direction.

[0024] As a preferred solution, further, a plurality of connecting steel bars 12 extend from the head end of the assembled cross beam 3 , and the plurality of connecting steel bars 12 and the plurality of supporting steel bars 2 are arranged in a staggered manner.

[0025] As a preferred solution, further, the overlap distance between the assembled cross beam 3 and the supporting column 1 is not less than 15 centimeters, which increases the overlap width and makes the connection more stable.

[0026] As a preferred solution, further, the width of the socket block 5 matches the width of the socket slot 4, and the length of the socket block 5 is longer than the length of the socket slot 4, so that part of the socket block 5 can be exposed from the socket slot 4 as needed, thereby facilitating fine-tuning installation.

[0027] As a preferred solution, further, the first bolt connection seat and the second bolt connection seat are both cylindrical internal threaded plates and are arranged in a bidirectional linear array to improve the load-bearing capacity and fixing stability.

[0028] From the above, it can be generally known that the reinforcement structure of the beam-column connection point of the prefabricated building is used at the beam-column connection position of the prefabricated building. By increasing the lap width and adaptively adding the design of the socket slot 4 and the socket block 5, the connection strength is improved. At the same time, the mutual limitation of the socket slot 4 and the socket block 5 is utilized to improve the horizontal seismic resistance of the beam-column position of the building, and the connection of the corner seat 9 is strengthened to further strengthen the connection between the beam and column.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
