Technical Field

[0001] The present invention relates to the technical field of assembled buildings, and in particular to an assembled steel structure frame for buildings. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. After the construction workpieces and accessories are processed and manufactured in the factory, they are transported to the construction site and assembled and installed on site through reliable connection methods. This better reflects the effect of civilized construction and dust reduction, while saving water and electricity resources and demonstrating the concept of green buildings. Steel structure frames are indispensable, and the main combination of steel structure frames is steel columns and support scales connected to each other.

[0003] At present, the steel columns and beams in the steel structure frame are directly fixed and connected with bolts. Especially in factory construction, if the factory building with assembled steel structure frame is to be relocated, it needs to be disassembled and then its main components can be used. However, the beams may bend during disassembly or transportation. It is also possible that due to changes in the factory construction design, the length of many beams may differ from the designed length and cannot be used again. In addition, the installation is difficult. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an assembled steel structure frame for construction that can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A prefabricated steel structure frame for construction, comprising: a plurality of steel columns, and also comprising: a crossbeam, arranged between two adjacent steel columns; a base, fixed on the side of the steel column close to the crossbeam; four limit rods, fixed in the base; a fixing plate, fixed on the side of the base near the steel column; a limit groove, provided on the fixing plate; a universal ball, sliding between the plurality of limit rods; a connecting column, fixed on the universal ball, and the connecting column slides in the limit groove; a mounting plate, fixed on one end of the connecting column away from the universal ball, the mounting plate being fixedly connected to the crossbeam via a connecting assembly; and a limit assembly for limiting the universal ball.

[0007] In order to facilitate the connection between the crossbeam and the mounting plate, preferably, the connection assembly includes mounting members symmetrically arranged on both sides of the crossbeam, and the mounting plate and the crossbeam are fixedly connected to the mounting members by first bolts.

[0008] In order to facilitate the pre-installation of the mounting member, further, a first through slot is provided on the cross beam, a second through slot is provided on the mounting member, a second bolt is provided between the first through slot and the second through slot, and a nut is threadedly connected to the second bolt.

[0009] In order to facilitate the limiting of the universal ball, preferably, the limiting assembly includes a top plate arranged on the upper side of the base, the two sides of the universal ball are symmetrically fixedly connected with fixing rods, the top plate is symmetrically fixedly connected with extrusion blocks matching the fixing rods, and the base is fixedly connected with a limiting block matching the universal ball.

[0010] To facilitate the fixation of the top plate, preferably, the lower end of the base is fixedly connected to a base, the base is provided with a first screw hole and a second screw hole, the top plate is symmetrically fixedly connected with a first screw rod and a second screw rod, the first screw rod matches the first screw hole, the second screw rod matches the second screw hole, and the upper end surface of the first screw hole is lower than the upper end surface of the second screw hole.

[0011] In order to facilitate the detection of the crossbeam, preferably, the base is symmetrically provided with limit holes, the top plate is fixedly connected with a limit sliding rod matching the limit holes, and a plurality of scale lines are equidistantly arranged on the limit sliding rod.

[0012] In order to facilitate the upper and lower limiting of the crossbeam, preferably, a threaded hole is opened on the top plate, and a limiting bolt is threadedly connected in the threaded hole.

[0013] In order to facilitate the vertical bending detection of the cross beam, preferably, a detection block matching the extrusion block is symmetrically fixedly connected to the fixing rod.

[0014] In order to facilitate the detection of the state of the crossbeam according to its length, further, the limit groove is arranged in an elliptical shape, and the short radius of the limit groove is arranged vertically.

[0015] In order to facilitate the placement of the crossbeam, preferably, the upper end surface of one side of the base matches the mounting plate.

[0016] Compared with the prior art, the present invention provides a prefabricated steel structure frame for construction, which has the following beneficial effects:

[0017] 1. The assembled steel structure frame of the building is installed on the mounting plate and the beam by the first bolt. After the installation is completed, the universal ball is limited by the limit assembly to install the beam. The universal ball that can be moved and the angle can be changed is matched with the mounting plate, thereby effectively improving the installation efficiency of the beam and the utilization rate of the beam, preventing the beam from being slightly bent during disassembly or transportation to affect the installation and reuse. The beams within a certain length range can be repeatedly installed and used, which is convenient for the reconstruction of the steel structure frame of the factory.

[0019] 3. The assembled steel structure frame of the building can accurately judge the distance between the top plate and the base through the scale lines on the limit slide rod, and at the same time can provide a guarantee for the same descending distance of the two top plates, thereby effectively improving the accuracy of the beam length and inclination detection. If the reused beam is slightly bent in the vertical direction, the fixed rod on the universal ball rotates to make the detection block rotate along the axis of the fixed rod, and the detection block protrudes toward the mounting plate, thereby performing a full-scale detection of the beam through the distance between the top plate and the base after the installation is completed, effectively preventing its lateral bending, vertical bending and substandard length from affecting the strength of the beam.

[0020] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The present invention effectively improves the installation efficiency of the beams and effectively improves the utilization rate of the beams, which is convenient for the reconstruction of the steel structure frame of the factory building. After the top plate is installed, the distance between the top plate and the base is used to perform all-round detection of the beams, effectively preventing their lateral bending, vertical bending and length not meeting the standards from affecting the strength of the beams.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1: Reference Figure 1-Figure 6 A prefabricated steel structure frame for building, comprising: a plurality of steel columns 1, and also comprising: a crossbeam 101, arranged between two adjacent steel columns 1; a base 2, fixed on the side of the steel column 1 close to the crossbeam 101; four limit rods 201, fixed in the base 2; a fixing plate 203, fixed on the side of the base 2 close to the steel column 1; a limit groove 204, opened on the fixing plate 203; a universal ball 3, sliding between the plurality of limit rods 201; a connecting column 303, fixed on the universal ball 3, and the connecting column 303 slides in the limit groove 204; a mounting plate 304, fixed on the end of the connecting column 303 away from the universal ball 3, and the mounting plate 304 is fixedly connected to the crossbeam 101 through a connecting component; a limit component for limiting the universal ball 3.

[0030] The connection assembly includes mounting members 4 symmetrically arranged on both sides of the crossbeam 101 , and the mounting plate 304 and the crossbeam 101 are fixedly connected to the mounting members 4 via first bolts 402 .

[0031] During the process of factory building relocation and reconstruction, the original steel structure frame is dismantled, and when it is rebuilt at the new factory site, the corresponding steel columns 1 are positioned and installed, and then the crossbeam 101 is installed between two adjacent steel columns 1.

[0032] During the installation of the crossbeam 101, the crossbeam 101 is hoisted to the designated position, the position of the mounting plate 304 is adjusted according to the length and bending angle of the crossbeam 101, and the mounting member 4 is mounted on the mounting plate 304 and the crossbeam 101 by means of the first bolt 402. After the installation is completed, the universal ball 3 is limited by the limiting assembly, so that the crossbeam 101 is installed. The universal ball 3 that can be moved and the angle can be changed is matched with the mounting plate 304, thereby effectively improving the installation efficiency of the crossbeam 101 and effectively improving the utilization rate of the crossbeam 101, preventing the crossbeam 101 from being slightly bent during disassembly or transportation to affect the installation and reuse. The crossbeams 101 within a certain length range can be repeatedly installed and used, thereby facilitating the reconstruction of the steel structure frame of the factory building.

[0033] Example 2: Reference Figure 1-Figure 6 A prefabricated steel structure frame for building is basically the same as Example 1, further, a first through slot 102 is opened on the cross beam 101, a second through slot 401 is opened on the mounting member 4, a second bolt 403 is arranged between the first through slot 102 and the second through slot 401, and a nut 404 is threadedly connected to the second bolt 403.

[0034] When installing the mounting member 4, first pre-fix the mounting member 4 by means of two second bolts 403 so that it is fixed on the cross beam 101, and then fix the mounting member 4 to the mounting plate 304 by means of the first bolt 402, and then tighten the second bolt 403 by means of the nut 404, so that the mounting member 4 is close to the cross beam 101, and finally fix the mounting member 4 to the cross beam 101 by means of the first bolt 402, so as to facilitate the fitting of the mounting member 4 to the cross beam 101 and effectively improve the installation accuracy.

[0035] Two adjacent mounting members 4 are locked by means of two second bolts 403 and nuts 404 , thereby effectively improving the stability of the mounting members 4 .

[0036] Example 3: Reference Figure 1-Figure 6 , an assembled steel structure frame for building, is basically the same as Example 1, and further, the limiting assembly includes a top plate 6 arranged on the upper side of the base 2, and the two sides of the universal ball 3 are symmetrically fixedly connected with fixed rods 301, and the top plate 6 is symmetrically fixedly connected with extrusion blocks 607 matching the fixed rods 301, and the base 2 is fixedly connected with a limiting block 202 matching the universal ball 3.

[0037] The lower end of the base 2 is fixedly connected to the base 5, and the base 5 is provided with a first screw hole 501 and a second screw hole 502. The top plate 6 is symmetrically fixedly connected to the first screw rod 601 and the second screw rod 602. The first screw rod 601 matches the first screw hole 501, and the second screw rod 602 matches the second screw hole 502. The upper end surface of the first screw hole 501 is lower than the upper end surface of the second screw hole 502.

[0038] When limiting the universal ball 3, the top plate 6 is installed on the base 5 through the first screw 601 and the second screw 602, and the top plate 6 is kept horizontal. The fixing rod 301 is squeezed by the extrusion block 607 to limit the universal ball 3. When installing the top plates 6 at both ends of the beam 101, the distances between the two top plates 6 and the base 5 are made as equal as possible, so that the beam 101 is set in the center, thereby effectively preventing the beam 101 from deviating to one side and causing uneven force.

[0039] When installing the top plate 6, if the first screw rod 601 does not contact the first screw hole 501, the length of the beam 101 is too short or the bending of the beam 101 is too large, and the beam 101 needs to be replaced. The distance that the extrusion block 607 descends can be used to effectively determine whether the length of the beam 101 is within the set range, and the degree of bending of the beam 101 can be detected. When the beam 101 bends laterally, the universal ball 3 tilts to one side. At this time, the fixing rod 301 on one side of the universal ball 3 tilts to the side close to the mounting plate 304, so that the distance between the top plate 6 and the base 5 can be used to determine whether the beam 101 is within the safe range, thereby effectively detecting the beam 101.

[0040] Example 4: Reference Figure 1-Figure 6 A prefabricated steel structure frame for construction is basically the same as Example 1, and further, a limiting hole 503 is symmetrically opened on the base 5, a limiting slide bar 603 matching the limiting hole 503 is fixedly connected to the top plate 6, and a plurality of scale lines 604 are equidistantly arranged on the limiting slide bar 603.

[0041] A threaded hole 605 is provided on the top plate 6 , and a limiting bolt 606 is threadedly connected to the threaded hole 605 .

[0042] A detection block 302 matching the extrusion block 607 is symmetrically fixedly connected to the fixing rod 301 .

[0043] When installing the top plate 6, the limiting slide bar 603 is inserted into the limiting hole 503 to limit the top plate 6 so that it can only move in the vertical direction. When installing the top plates 6 at both ends of the beam 101, the scale lines 604 on the limiting slide bar 603 can be used to accurately judge the distance between the top plate 6 and the base 5. At the same time, it can provide a guarantee that the two top plates 6 descend by the same distance, thereby effectively improving the accuracy of the length and inclination detection of the beam 101.

[0044] If the reused beam 101 is slightly bent in the vertical direction, the installation angle of the mounting plate 304 can be adjusted through the universal ball 3, and the fixing rod 301 on the universal ball 3 rotates at this time, so that the detection block 302 rotates along the axis of the fixing rod 301, and the detection block 302 protrudes toward the mounting plate 304, so that the beam 101 is fully detected through the distance between the top plate 6 and the base 5 after installation, effectively preventing its lateral bending, vertical bending and length not meeting the standard from affecting the strength of the beam 101.

[0045] A certain extrusion force is applied to the fixing rod 301 through the extrusion block 607, so that a certain correction force can be provided to the beam 101. After the installation of the entire steel structure frame is completed, the first screw 601 and the second screw 602 are tightened again, and the beam 101 is limited by tightening the limit bolt 606. The limit bolt 606 cooperates with the base 5 to fix the upper and lower sides of the beam 101, which effectively improves the stability of the steel structure frame of the beam 101.

[0046] Example 5: Reference Figure 1-Figure 6 , an assembled steel structure frame for construction, which is basically the same as Example 1, and further, the limiting groove 204 is arranged in an elliptical shape, and the short radius of the limiting groove 204 is arranged vertically.

[0047] Through the elliptical limit groove 204, the vertical bending of the beam 101 can be strictly detected to prevent the vertical bending of the beam 101 from being too large and affecting the supporting strength of the beam 101. In addition, the longer the beam 101 is, the larger the distance between the universal ball 3 and the fixed plate 203 is. At this time, the requirement on the bending degree of the beam 101 through the limit groove 204 is more stringent, thereby effectively improving the accuracy of the detection of the beam 101.

[0048] By performing double detection on the limiting groove 204 and the top plate 6, the detection accuracy of the cross beam 101 is effectively improved, thereby effectively preventing the severely damaged cross beam 101 from affecting the strength of the steel structure frame.

[0049] The upper end surface of one side of the base 5 matches the mounting plate 304 .

[0050] The cross beam 101 is pre-supported by the base 5 , thereby effectively reducing the difficulty of installing the cross beam 101 .

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
