Description

Technical Field

[0001] The invention relates to the technical field of steel structure assembly, and in particular to a steel structure assembly connection method and assembly connection equipment. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly.

[0003] The horizontal and vertical main frames of the steel structure need to be connected by a connecting structure. Currently, there are many forms of steel structure monomers. For example, the most common I-beam can be directly connected by steel plates and bolt structures. In addition to the I-beam steel structure, there is also a closed plug-in connection steel structure, which is stronger than the I-beam in all aspects and is needed in large quantities in some special projects. However, after being connected to each other, the interior is in a closed state and cannot be connected using traditional bolt structures. Instead, expansion screws are required, resulting in a relatively high overall cost. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a steel structure assembly connection method and an assembly connection device, which solves the problem that the plug-in part of the steel structure in the closed plug-in connection method is in a closed state inside, cannot be connected using a traditional bolt structure and requires the use of expansion screws, resulting in a high overall cost.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a steel structure assembly connection device, comprising two side plates arranged vertically and parallel to each other, the top and bottom ends of the surfaces of the two side plates on opposite sides are extended in the direction of the opposite side to form four extension strips, the two extension strips at both ends correspond to each other, and a spacing adjustment structure for adjusting the spacing between the two side plates is provided between each two corresponding extension strips;

[0006] The outer surfaces of the two side plates are transversely provided with a plurality of nut grooves whose contours match the outer contours of standard nuts, and the inner end surfaces of the plurality of nut grooves are transversely penetrated with through holes coaxial therewith.

[0007] Furthermore, the structures of the two spacing adjustment structures are the same, and one of the spacing adjustment structures includes sliding grooves opened at the front parts of the surfaces of the opposite sides of the two extension bars along the length directions of the two extension bars, the interiors of the two sliding grooves are respectively connected with threaded rods that are laterally rotatable along their length directions, the outer surfaces of the two threaded rods are threadedly connected with threaded sleeves, and the outer surfaces of the two threaded sleeves are respectively fixedly connected with sliders that are respectively slidably connected to the interiors of the two sliding grooves.

[0008] Furthermore, the surfaces on the opposite sides of the two sliders are fixedly connected with a first connecting seat, and the rear ends of the surfaces on the opposite sides of the two extension strips are fixedly connected with a second connecting seat, and the two first connecting seats respectively correspond to the second connecting seats on the other side, and a hinged rod is hinged between the corresponding first connecting seat and the second connecting seat.

[0009] Furthermore, the middle parts of the two hinged rods are hinged to each other.

[0010] Furthermore, the front parts of the outer surfaces of the two threaded rods are fixedly connected with first pulleys, and the two first pulleys are connected via belt transmission.

[0011] Furthermore, the front ends of the threaded rods on the same side of the two spacing adjustment structures can rotatably pass through the front end surface of the extension strip and extend forward, and the outer surfaces of the two threaded rods and the front parts of the extension strips are fixedly connected with second pulleys, and the two second pulleys are connected by belt transmission.

[0012] Furthermore, a cross knife groove is provided on the outer end surfaces of the two threaded rods and located in front of the extension strip, and the top and bottom ends of the front end surfaces of the two side panels are fixedly connected to the limiting blocks.

[0013] A steel structure assembly and connection method comprises the following steps:

[0014] S1. Install standard nuts inside the nut grooves on the outer surfaces of the two side panels;

[0015] S2, inserting the two side panels into the port of the closed crossbeam connector until the plurality of limit blocks on the two side panels fit with the port surface of the crossbeam connector;

[0016] S3, rotating the outer end of the threaded rod protruding outward in one of the spacing adjustment structures, under the action of the first pulley and the second pulley, the sliders in the two spacing adjustment structures will move inward, and under the action of the two hinged rods, the two side plates are separated from each other until the multiple nuts on the outer surfaces of the two side plates are respectively fitted with the two side surfaces inside the crossbeam connector;

[0017] S4, insert the crossbeam connector into the connector frame reserved outside the load-bearing column, insert the screw through the holes on both sides of the connector frame and the connector, and tighten it into the nut located inside the connector;

When the device is in use, a plurality of nuts are placed in the plurality of nut grooves respectively and then the device is directly inserted into the steel beam connector. The two side panels are then pushed to move toward the two sides of the connector until the nuts on the two side panels are tightly fitted with the two side surfaces of the connector. The connector is then inserted into the connector frame. At this time, the connection holes reserved on the connector frame and the connector will be aligned with each other, and these connection holes will also be aligned with the plurality of nuts respectively.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-5 The present invention provides a technical solution: a steel structure assembly connection device, comprising two side panels 1 arranged vertically and parallel to each other, the top and bottom ends of the surfaces of the two side panels 1 on opposite sides are extended in the direction of the opposite side to form four extension strips 2, the two extension strips 2 at both ends correspond to each other, and a spacing adjustment structure for adjusting the spacing between the two side panels 1 is arranged between each two corresponding extension strips 2;

[0030] The outer surfaces of the two side plates 1 are transversely provided with a plurality of nut grooves 14 whose contours match the outer contours of standard nuts, and the inner end surfaces of the plurality of nut grooves 14 are transversely penetrated with coaxial through holes 15 therethrough.

[0031] When the device is in use, after placing multiple nuts in multiple nut grooves 14 respectively, the device is directly inserted into the steel beam connector, and then the two side panels 1 are pushed to move to both sides of the connector until the nuts on the two side panels 1 are tightly fitted with the two side surfaces of the connector, and then the connector is inserted into the connector frame. At this time, the connection holes reserved on the connector frame and the connector will be aligned with each other, and these connection holes will also be aligned with the multiple nuts respectively. The staff only needs to pass the screws through the multiple connection holes and tighten them on the nuts to complete the connection of the steel structure. The closed steel structure can be installed without using expansion screws, which reduces the installation cost.

[0032] The nut grooves 14 opened on the two side panels 1 of the device correspond to the connecting holes opened on the side edges of the steel structure's plug-in parts and the plug-in frame, and when tightening the screw, since the inner contour of the nut groove 14 matches the outer contour of the standard nut, the nut cannot rotate inside the nut groove 14, thereby ensuring the stability of the final installation of the bolt structure.

[0033] The structures of the two spacing adjustment structures are the same, and one of the spacing adjustment structures includes a slide groove 3 opened at the front part of the surface of the opposite side of the two extension bars 2 along the length direction of the two extension bars 2, and the interiors of the two slide grooves 3 are respectively connected with threaded rods 4 for transverse rotation along their length directions. The outer surfaces of the two threaded rods 4 are threadedly connected with threaded sleeves 5, and the outer surfaces of the two threaded sleeves 5 are respectively fixedly connected with sliders 6 that are respectively slidably connected to the insides of the two slide grooves 3.

[0034] The surfaces of the opposite sides of the two sliders 6 are fixedly connected with the first connecting seats 7, and the rear ends of the surfaces of the opposite sides of the two extension strips 2 are fixedly connected with the second connecting seats 8. The two first connecting seats 7 correspond to the second connecting seats 8 on the other side respectively, and a hinged rod 9 is hinged between the corresponding first connecting seats 7 and the second connecting seats 8.

[0035] The middle parts of the two hinged rods 9 are hinged to each other.

[0036] When the threaded rod 4 is rotated, the threaded sleeve 5 on its surface will move along its length direction. When the threaded sleeve 5 moves backward, it will drive the slider 6 fixedly connected to it to move backward synchronously. In this process, the distance between the first connecting seat 7 and the second connecting seat 8 will be shortened. Since a fixed-length hinged rod 9 is arranged between the two, the hinged rod 9 will push the two side panels 1 outward in this process.

[0037] This structure ensures that the device will not be unable to be quickly and smoothly placed inside the steel structure due to errors in the steel structure during actual use, thereby improving the efficiency of the overall operation.

[0038] The front parts of the outer surfaces of the two threaded rods 4 are fixedly connected with first pulleys 10 , and the two first pulleys 10 are connected via belt transmission.

[0039] The front ends of the threaded rods 4 on the same side of the spacing adjustment structures can be rotatably passed through the front end surface of the extension strip 2 and extend forward, and the outer surfaces of the two threaded rods 4 and the front part of the extension strip 2 are fixedly connected with the second pulleys 11, and the two second pulleys 11 are connected by belt transmission.

[0040] Under the action of the first pulley 10 and the second pulley 11, the multiple threaded rods 4 will rotate synchronously in the same direction, so that the upper and lower spacing adjustment structures always remain synchronized, ensuring the stability of the two side panels 1 during movement and preventing skew problems.

[0041] A cross knife groove 12 is formed on the outer end surfaces of the two threaded rods 4 and located in front of the extension strip 2 , and the top and bottom ends of the front end surfaces of the two side panels 1 are fixedly connected to the limiting blocks 13 .

[0042] The limit block 13 can limit the device to prevent the device from being inserted too deeply into the connector, and can also ensure that the multiple nut slots 14 on the device can be well aligned with the connection holes reserved on the steel structure.

[0043] A steel structure assembly and connection method comprises the following steps:

[0044] S1, installing standard nuts inside the nut grooves 14 on the outer surfaces of the two side panels 1;

[0045] S2, inserting the two side panels 1 into the port of the closed crossbeam connector until the plurality of limit blocks 13 on the two side panels 1 fit with the port surface of the crossbeam connector;

[0046] S3, rotate the outer end of the threaded rod 5 protruding outward in one spacing adjustment structure, and under the action of the first pulley 10 and the second pulley 11, the sliders 6 in the two spacing adjustment structures will move inward, and under the action of the two hinged rods 9, the two side panels 1 are separated from each other until the multiple nuts on the outer surfaces of the two side panels 1 are respectively fitted with the two side surfaces inside the crossbeam connector;

[0047] S4, insert the crossbeam connector into the connector frame reserved outside the load-bearing column, insert the screw through the holes on both sides of the connector frame and the connector, and tighten it into the nut located inside the connector;

[0048] S5. Weld the connection parts between the connector and the connector frame.

[0049] When the device is in use, after placing multiple nuts in multiple nut grooves 14 respectively, the device is directly inserted into the steel beam connector, and then the two side panels 1 are pushed to move to both sides of the connector until the nuts on the two side panels 1 are tightly fitted with the two side surfaces of the connector, and then the connector is inserted into the connector frame. At this time, the connection holes reserved on the connector frame and the connector will be aligned with each other, and these connection holes will also be aligned with the multiple nuts respectively. The staff only needs to pass the screws through the multiple connection holes and tighten them on the nuts to complete the connection of the steel structure. The closed steel structure can be installed without using expansion screws, which reduces the installation cost.
