[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled building prefabricated beam. Background Art

[0002] Prefabricated building beams refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as exterior wall panels, interior wall panels, composite panels, balconies, air-conditioning panels, stairs, prefabricated beams, prefabricated columns, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods.

[0003] The publication number in the existing public technology is: CN219863284U. A prefabricated beam for assembled buildings includes a column and a beam. Two beams are provided, and the column is located between the two beams. The left and right sides of the column are provided with grooves, and the inside of the grooves on the left and right sides are provided with two rows of screw holes, and the two beams are adapted with upper and lower fixing blocks, each of which is L-shaped, and one side of each fixing block is provided with two plug holes, and the two beams are provided with upper and lower plug holes on the side of the two beams that are biased toward the groove, and each fixing block is fixedly connected to one end of the beam that is biased toward the beam, and a spring is fixedly connected to the inside of each plug hole, and one end of each spring that is biased toward the plug hole is fixedly connected to a partition, and the two ends of each partition are respectively fitted with the plug hole. When the utility model is actually used, the assembly height of the assembled building can be changed according to the different use environments, and the operation is relatively simple and practical.

[0004] The existing technology has the following problems:

[0005] Although it can connect the column and the beam, it requires personnel to support the beam for a long time during installation, and it takes a lot of effort to align the threaded holes between the structures. The operation is time-consuming and laborious. In addition, due to the grooves opened, there will be certain vacancies on the side of the column. After the subsequent beam is installed, there will still be certain vacancies on the surface, which greatly reduces the strength of the grooves, is not conducive to long-term use, and the overall use effect is not very ideal.

[0006] To this end, we proposed an assembled building prefabricated beam to solve the above-mentioned drawbacks. Utility Model Content

[0007] The utility model aims to solve the shortcomings in the prior art and proposes an assembled building prefabricated beam.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a column and a beam, a plurality of groups of assembly grooves are evenly opened on the surface of one side of the column, a sealing groove is opened on one side of the assembly groove, a filling plate and a beam are respectively inserted into the inner position of the assembly groove, protrusions are symmetrically welded at the middle position at both ends of the inner part of the assembly groove, limit strips are provided at both ends of the surface of one side of the beam, and the limit strip and the beam are an integrally formed structure, a limit slot is opened in the middle position of the surface of the limit strip, and positive threaded holes are correspondingly opened at both ends of the inner position of the assembly groove and on the surface of the limit strip.

[0009] Preferably, a sealing plate is clamped at an inner position of the sealing groove.

[0010] Preferably, side threaded holes are correspondingly provided at both end positions inside the sealing groove, at both end positions on the surface of the filling plate, and at both end positions on the surface of the sealing plate.

[0011] Preferably, the sum of the thickness of the blocking plate and the thickness of the crossbeam is the same as the depth of the assembly groove.

[0012] Preferably, the size of the filling plate is the same as the size of the assembly slot.

[0014] Preferably, the protrusion is a trapezoidal structure.

[0015] Preferably, the depth of the limiting groove is the same as the thickness of the protrusion of the bump.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model adopts an assembly groove, a protrusion and a limit groove. When working, the personnel can take out the filling plate at the corresponding position according to the different heights of the beam installation, and then push the beam directly into the assembly groove. When a click sound is heard, it means that the protrusion inside the assembly groove is inserted into the limit groove on the surface of the beam. At this time, the beam can be initially fixed through the assembly groove. At this time, the personnel do not need to support the beam for a long time, and the positive threaded holes on the surface of the beam and in the assembly groove can be accurately aligned. The personnel do not need to spend a lot of energy on manual processing, which can effectively reduce labor intensity and improve the work efficiency of the personnel. It has the advantages of convenient assembly pre-fixation and high-precision hole alignment.

In this way, the entire assembly groove can be filled, avoiding the deformation of the structure when it is subsequently compressed due to the existence of gaps, which can effectively ensure the overall use strength, improve the use effect of the structure, and has the advantage of high use strength.

[0028] In this embodiment, a blocking plate 11 is clamped in the inner position of the blocking groove 5 .

[0029] Specifically, the blocking plate 11 is provided to fill the vacancy of the assembly groove 6 when the cross beam 4 is installed, and at the same time, the cross beam 4 can be locked for a second time to improve the stability during assembly and prevent it from falling out of the assembly groove 6.

[0030] In this embodiment, side threaded holes 3 are correspondingly provided at both ends of the interior of the blocking groove 5 , at both ends of the surface of the filling plate 2 , and at both ends of the surface of the blocking plate 11 .

[0031] Specifically, the positive threaded hole 8 and the side threaded hole 3 are both common threaded holes, which are distinguished here only according to the difference in position without changing their specific shapes, so they are not described in detail.

[0032] In this embodiment, the sum of the thickness of the blocking plate 11 and the thickness of the crossbeam 4 is the same as the depth of the assembly groove 6 .

[0033] Specifically, the dimensional relationship between the filling plate 2, the blocking plate 11, the crossbeam 4 and the assembly groove 6 is to ensure that the assembly groove 6 can be fully filled during use, to avoid the existence of gaps that cause the column 1 to bend and deform after being compressed, and to improve the overall strength of use.

[0034] In this embodiment, the size of the filling plate 2 is the same as the size of the assembly groove 6 .

[0035] Specifically, the dimensional relationship between the filling plate 2, the blocking plate 11, the crossbeam 4 and the assembly groove 6 is to ensure that the assembly groove 6 can be fully filled during use, to avoid the existence of gaps that cause the column 1 to bend and deform after being compressed, and to improve the overall strength of use.

[0036] In this embodiment, the materials of the filling plate 2 and the blocking plate 11 are the same as those of the column 1 and the beam 4 .

[0037] Specifically, the materials of the column 1 and the beam 4 are common knowledge in actual production and life, so they will not be described in detail.

[0038] In this embodiment: the projection 7 is a trapezoidal structure.

[0039] Specifically, the projection 7 is provided to initially restrict the cross beam 4 when the cross beam 4 and the column 1 are in use, and to play a certain fixing role, so as to prevent the cross beam 4 from falling after being let go by a person, and to facilitate the subsequent bolt installation.

[0040] In this embodiment, the depth of the limiting groove 10 is the same as the protruding thickness of the protrusion 7 .

[0041] Specifically, the size of the limit groove 10 and the protrusion 7 is set to ensure that the beam 4 can play a certain fixing role with the assembly groove 6 after the two are plugged in, preventing the beam 4 from falling off when personnel do not support the beam 4, reducing the operating intensity of personnel, and allowing personnel to perform subsequent operations.

[0042] In this implementation scheme: the side threaded holes and the positive threaded holes are common knowledge in the art and are only used without modification, so the control method and circuit connection are not described in detail.

[0043] Working principle: During operation, personnel can take out the filling plate 2 at the corresponding position according to the different installation heights of the crossbeam 4, and then push the crossbeam 4 directly into the assembly groove 6. When a click sound is heard, it means that the protrusion 7 inside the assembly groove 6 is inserted into the limit groove 10 on the surface of the crossbeam 4. At this time, the crossbeam 4 can be initially fixed through the assembly groove 6, and the structure will not fall off due to the separation of personnel. At this time, personnel do not need to support the crossbeam 4 for a long time, and the positive threaded holes 8 on the surface of the crossbeam 4 and in the assembly groove 6 can be accurately aligned, and personnel do not need to spend a lot of energy on manual processing, which can effectively reduce labor intensity and improve personnel's work efficiency. After the crossbeam 4 is inserted, the entire assembly groove 6 can be filled by inserting the blocking plate 11 into the blocking groove 5 inside the assembly groove 6, so as to avoid the deformation of the structure during subsequent pressure caused by the existence of gaps, which can effectively ensure the overall use strength and improve the use effect of the structure. The device as a whole has the advantages of assembly pre-fixation, convenient hole alignment, high precision and high use strength.
