Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building engineering, and in particular to a beam reinforcement structure for building engineering. Background Technology
[0002] In building construction, beam reinforcement typically refers to technical measures that strengthen and repair existing beam structures to improve their load-bearing capacity, extend their service life, or meet new design requirements. When the span of a beam is large, it is usually necessary to fix two or more beams together before reinforcement. For example... Figure 1 As shown, the webs of two I-beams are connected by steel plates, and then steel plates are used to reinforce the flanges of the beams. Although this method of reinforcement with steel plates is relatively simple, the tensile and compressive strength of the steel plates is limited, resulting in poor reinforcement. Utility Model Content
[0003] In order to improve the tensile and compressive strength of engineering beams, this application provides a reinforcement structure for building engineering beams.
[0004] On one hand, this application proposes a beam reinforcement structure for building engineering, used to reinforce two I-shaped crossbeams, including a reinforcement beam body, a connecting assembly, and a reinforced concrete structure. The reinforcement beam body is located at the bottom of the connection position of the two crossbeams, and has a predetermined length; the connecting assembly includes a first connector and a second connector, both of which have C-shaped cross-sections, and are respectively fastened to the lower edge of the crossbeam and the outer side of the reinforcement beam body, and are fixedly connected by longitudinally penetrating bolts and nuts; the reinforced concrete structure is located between the lower edge of the crossbeam and the reinforcement beam body, and includes reinforcing bars and cast-in-place concrete, the reinforcing bars extending along the length direction of the reinforcement beam body, and the cast-in-place concrete filling the gap between the lower edge of the crossbeam and the reinforcement beam body.
[0005] By adopting the above technical solution, the reinforced beam is fixed at the connection position of the two crossbeams through the first connector and the second connector. The first connector and the second connector are fastened to the outside of the reinforced beam and the crossbeam, and a steel-concrete structure is set between the reinforced beam and the crossbeam, thereby improving the tensile and compressive strength of the reinforced structure, which in turn helps to improve the load-bearing capacity of the beams in the building project.
[0006] Optionally, the cross-sectional shape of the reinforced beam is U-shaped, the steel-concrete structure is disposed within the reinforced beam, and the upper edge of the reinforced beam abuts against the lower edge of the crossbeam.
[0007] By adopting the above technical solutions, the U-shaped reinforced beam has a larger section modulus than a steel plate, thus exhibiting higher structural strength and greater tensile and compressive strength. Furthermore, the upper edge of the reinforced beam abuts against the lower edge of the crossbeam, making the structure even more stable.
[0008] Optionally, the width of the reinforced beam is equal to the width of the lower part of the crossbeam.
[0009] By adopting the above technical solutions and appropriately increasing the width of the reinforced beam, its section modulus can be increased, thereby improving the tensile and compressive strength of the reinforced beam.
[0010] Optionally, the upper and lower inner walls of the first connector and the second connector respectively abut against the upper edge of the crossbeam and the lower edge of the reinforced beam.
[0011] By adopting the above technical solutions, the structure can be made more compact, which is conducive to improving the overall structural strength, thereby increasing the tensile and compressive strength of the reinforced structure.
[0012] Optionally, the end of the reinforced beam is fixedly connected to the longitudinal beam on the outside of the crossbeam.
[0013] By adopting the above technical solutions, the connection between the reinforced beam and the longitudinal beam is strengthened, which helps to increase the structural strength of the reinforced beam and make the reinforced structure a more stable whole.
[0014] Optionally, adjacent reinforcing bars are fixedly connected by transversely arranged reinforcing bars.
[0015] By adopting the above technical solutions, the reinforcement bars can make the connection between the steel bars more stable, which in turn helps to improve the stability of the steel-concrete structure and increase its tensile and compressive strength.
[0016] Optionally, both ends of the reinforcing rib are fixedly connected to the inner wall surface of the reinforced beam.
[0017] By adopting the above technical solutions, the connection between the reinforcing bars and the reinforced beam can make the reinforcing bars more stable, thereby forming a stable whole with the reinforcing bars, the reinforced beam and the steel bars, thus giving it higher strength.
[0018] In summary, this utility model has at least one of the following beneficial technical effects:
[0019] 1. The reinforced beam is fixed to the connection position of the two crossbeams by the first connector and the second connector. The first connector and the second connector are fastened to the outside of the reinforced beam and the crossbeams. A steel-concrete structure is set between the reinforced beam and the crossbeams, thereby improving the tensile and compressive strength of the reinforced structure, which in turn helps to improve the load-bearing capacity of the beams in the building project.
[0020] 2. By designing the reinforced beam in a U-shape, the U-shaped reinforced beam has a larger section modulus than a steel plate, resulting in higher structural strength and higher tensile and compressive strength. Furthermore, the upper edge of the reinforced beam abuts against the lower edge of the crossbeam, making the structure more stable. Attached Figure Description

Detailed Implementation

The detailed description of the following embodiments and the accompanying drawings are used to illustrate the principles of this application by way of example, but should not be used to limit the scope of this application, that is, this application is not limited to the described embodiments.
[0026] In the description of this application, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," etc., indicating orientation or positional relationships are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0027] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.
[0028] In related technologies, steel plates are usually used to reinforce the space between two beams. Although the steel plate reinforcement structure is simple to construct, its tensile and compressive strength is limited, resulting in poor reinforcement effect.
[0029] Based on this, embodiments of this application provide a beam reinforcement structure for building engineering to solve the aforementioned technical problems. The beam reinforcement structure for building engineering provided in embodiments of this application is described below.
[0030] like Figure 2 and Figure 3 As shown in the embodiment of this application, a beam reinforcement structure for building engineering is provided for reinforcing two I-beams 40, including a reinforced beam body 10, a connecting component 20, and a steel-concrete structure 30.
[0031] The reinforcing beam 10 is set at the bottom of the connection position of the two crossbeams 40. The reinforcing beam 10 has a predetermined length, which is generally set between 80cm and 300cm. Of course, the length of the reinforcing beam 10 can also be selected according to the situation.
[0032] The reinforced beam 10 has a U-shaped cross-section, and the reinforced concrete structure 30 is installed inside the reinforced beam 10. The upper edge of the reinforced beam 10 abuts against the lower edge of the crossbeam 40. The U-shaped reinforced beam 10 has a larger section modulus, thus giving the reinforced beam 10 higher tensile and compressive strength.
[0033] The width of the reinforced beam 10 is equal to the width of the lower part of the crossbeam 40, which makes the structure more reasonable and helps to increase the section modulus of the reinforced beam 10, thereby further improving the tensile and compressive strength of the reinforced beam 10.
[0034] In addition, the end of the reinforced beam 10 can be fixedly connected to the longitudinal beam 50 on the outside of the crossbeam 40, which helps to increase the structural strength of the reinforced beam 10 and make the reinforced structure a more stable whole.
[0035] The connecting assembly 20 includes a first connector 21 and a second connector 22. The cross-sectional shape of the first connector 21 and the second connector 22 is C-shaped. The first connector 21 and the second connector 22 are respectively fastened to the lower part of the crossbeam 40 and the outer side of the reinforcing beam 10, and are fixedly connected by longitudinally penetrating bolts and nuts.
[0036] The upper and lower inner walls of the first connector 21 and the second connector 22 respectively abut against the upper part of the crossbeam 40 and the lower edge of the reinforced beam 10, thereby making the structure more compact and improving the tensile and compressive strength of the reinforced structure.
[0037] The steel-concrete structure 30 is set between the lower part of the crossbeam 40 and the reinforced beam 10. The steel-concrete structure 30 includes steel bars 31 and cast-in-place concrete 32. The steel bars 31 extend along the length of the reinforced beam 10, and the cast-in-place concrete 32 fills the gap between the lower part of the crossbeam 40 and the reinforced beam 10.
[0038] Adjacent reinforcing bars 31 are fixedly connected by transversely arranged reinforcing bars 33, which makes the connection between the reinforcing bars 31 more stable, thereby improving the stability of the reinforced concrete structure 30. Specifically, the reinforcing bars 31 and the reinforcing bars 33 can be fixedly connected by welding, and the reinforcing bars 31 and the reinforcing bars 33 can be prefabricated in the reinforced beam 10.
[0039] In addition, the two ends of the reinforcing rib 33 are fixedly connected to the opposite inner wall surfaces of the reinforced beam 10, thereby making the reinforcing rib 33 more stable. This allows the reinforcing rib 33, the reinforced beam 10, and the reinforcing bar 31 to form a stable whole, giving it higher strength. Specifically, the reinforcing rib 33 and the reinforced beam 10 can be fixed together by welding.
[0040] The implementation principle of the beam reinforcement structure in this application is as follows:
[0041] The reinforcing beam 10 is placed at the bottom of the connection position of the two crossbeams 40, and the reinforcing beam 10 is welded and fixed to the longitudinal beam 50 on the outside of the crossbeam 40. The first connecting piece 21 and the second connecting piece 22 are respectively fastened to the outside of the reinforcing beam 10 and the crossbeam 40, and then the first connecting piece 21, the second connecting piece 22, and the corresponding crossbeam 40 and the reinforcing beam 10 are fixed by bolts and nuts.
[0042] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
