Abstract

The invention discloses an integrated steel connecting inserting plate. The integrated steel connecting inserting plate comprises inserting plate bodies, wherein a connecting part and an assembling part are arranged on each inserting plate body, the connecting parts are fixedly connected with the ends of integrated steel, a plurality of mounting holes are formed in each assembling part, and boltsand/or plug pins penetrate through the mounting holes of the two inserting plate bodies to form connection of the two pieces of integrated steel. According to the integrated steel connecting insertingplate, a unique integrated steel connecting mode is provided, namely, the inserting plate bodies at the ends of the integrated steel are assembled in pairs, so that the connection of the two pieces of integrated steel is rapidly completed, a large amount of welding is not needed on site, the construction efficiency is high, the operation is simple, the connecting strength is guaranteed, and the on-site construction convenience is greatly improved. The invention further discloses a machining method of the integrated steel connecting inserting plate.

Example Embodiment

[0029] The technical scheme of the present invention will be further explained with reference to the drawings and specific embodiments.

[0030] see also Figures 1 to 5 As shown, this embodiment provides an integrated section steel connection board, which comprises a board body 1, wherein the board body 1 is provided with a connecting part 11 and an assembling part 12, the connecting part 11 is fixedly connected with the end of the integrated section steel 4, and the assembling part 12 is provided with a plurality of mounting holes, and bolts and/or pins are used to pass through the mounting holes of the two board bodies 1 to form the connection of the two integrated sections steel 4.

[0031] The connection is more reliable when the bolt acts with the bolt at the same time. According to the connection form of the bolt and the bolt, the mounting holes here are divided into bolt mounting holes 13 and pin mounting holes 14. It should be noted that the bolt mounting holes 13 corresponding to the bolt connection are set as waist holes, and the waist holes on the two plug-in board bodies are preferably vertically arranged, and the anti-expansion bolts 2 are inserted into the bolt mounting holes 13 to fasten the two plug-in board bodies 1. However, there is a height difference δ between the two pin mounting holes 14 connected by bolts. After the shear pin 3 is inserted, it can form a pre-tightening force on the two plug-in board bodies 1, thus forming a stronger connection structure.

[0032] Particularly, a transition section is arranged between the connecting part and the assembling part, and the transition section forms a non-zero included angle with the connecting part and the assembling part respectively.

[0033] The plug-in board body 1 can be separated from the integrated section steel 4, or the plug-in board body 1 and the integrated section steel 4 can be integrally formed. When being separated, the integrated section steel 4 to be connected is provided with a slot 41, and the connecting part 11 is inserted into the slot 41 and fixed by welding. The connection between the plug-in board body 1 and the integrated section steel 4 can be completed at the factory, and can be directly assembled and used on site.

[0034] In addition, the integrated section steel 4 here can be a square member, an I-shaped member, an L-shaped member, a T-shaped member, etc. composed of U-shaped steel and square tubes, such as Figure 6-11As shown, this plug-in board structure can be applied, and it only needs to be correspondingly formed or slotted.

[0035] There is a transition section 15 between the connecting section 11 and the assembling section 12, and the transition section 15 forms a non-zero included angle with the connecting section 11 and the assembling section 12, respectively.

[0036] The end edge of the assembly part 12 is provided with a guide inclined plane 16 which is convenient for insertion, so that the two plug-in board bodies can accurately reach the assembly position during assembly.

[0037] Since the connecting part 11 is a stress concentration place, the thickness of the assembling part 12 should be larger than that of the connecting part 11. In fact, the thickness of the connecting part 11 is slightly thicker than that of the integrated steel 4, while the thickness of the assembling part 12 is about twice that of the integrated steel 4, so as to ensure the connection strength. Specifically, the thickness of the assembling part 12 is proportional to the upper opening area.

[0038] Construction process: splice the plug-in board body 1 of one integrated section steel with the plug-in board body 1' of another integrated section steel by a crane, and determine the relative positions of the two integrated sections in the horizontal and vertical directions; Insert the anti-expansion bolts 2 into the bolt mounting holes 13 on the two plug board bodies to realize fastening; There is a height difference Δ between the pin mounting holes 14 on the two plug-in boards, and the insertion of the shear pin 3 produces plastic deformation, which produces pre-tightening force and improves shear resistance; Grouting into the integrated section steel 4.

[0039] This embodiment also correspondingly provides a processing method of the integrated steel 4 connecting plug board. As a split piece, the plug board main body 1 is formed by hot rolling a steel plate, and the bolt mounting holes 13 and pin mounting holes 14 on it are processed by punching, gas cutting, laser and etching.

[0040] When that plug-in board body 1 and the integrate section steel 4 are of an integrated structure, the plug-in board body 1 can be integrally extended while the integrate section steel 4 is molded, and the bolt mounting holes 13 and pin mount holes 14 on the plug-in board body 1 can also be processed by punching, gas cutting, laser, etching and the like.

[0041] To sum up, the above-mentioned integrated section steel connecting plugboard and its processing method provide a unique integrated section steel connecting mode, that is, by assembling the plugboard bodies at the ends of the integrated sections in pairs, the connection of two integrated sections can be quickly completed, and there is no need for a large number of welding on site. The construction efficiency is high, the operation is simple, the connection strength is guaranteed, and the convenience of site construction is greatly improved.

[0042] The above examples only illustrate the basic principles and characteristics of the invention, and the invention is not limited by the above examples. On the premise of not departing from the spirit and scope of the invention, there are various changes and modifications of the invention, all of which fall within the scope of the claimed invention. The scope of that invention is define by the appended claim and their equivalents.
