[0022] The following are specific embodiments of this utility model, and the technical solution of this utility model will be further described with reference to the accompanying drawings. However, this utility model is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, all combinations of features described in the embodiments are not necessarily necessary for the solution of the utility model.

[0023] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. Example

[0024] like Figure 1 , 2 As shown in Figures 3 and 4, a steel structure module connection device is used to vertically assemble two steel structure modules, wherein the steel structure module is an I-beam, and the connection device is installed on the steel structure column 1 on the side of the I-beam, that is, on the end side plate of the I-beam.

[0025] The connecting device includes a guide fixedly connected to each of the steel structure modules and a guide pin 2 connecting the guide. The guide includes a guide tube 3 fixed relative to the steel structure module. When two steel structure modules are vertically aligned, the guide tubes 3 on the two steel structure modules are coaxially aligned vertically. The guide pin 2 has a first end and a second end that insert into two adjacent guide tubes 3 vertically. A locking section with a diameter larger than the inner diameter of the guide tube 3 is provided between the first end and the second end of the guide pin 2. The guide tube 3 is a steel pipe.

[0026] The connecting device further includes a mounting plate 4 for detachable connection with the steel structure module, and the guide tube 3 is fixed to the mounting plate 4. The mounting plate 4 is connected to the steel structure module by bolts 7. Both ends of the guide tube 3 are connected to the mounting plate 4 by fixing plates 5. The mounting plate 4 is also made of steel plate.

[0027] During manufacturing, first prepare four fixing plates 5 of appropriate size. Make a hole slightly larger than the outer diameter of the guide tube 3 at the same position on the fixing plate 5. The hole should be in the same position on the two fixing plates 5. First, insert the two ends of the guide pin 2 into the guide tube 3. Then, pre-assemble the guide tube 3 and the fixing plate 5 according to the drawings. After pre-assembly, check whether the gap between the guide pin 2 and the guide tube 3 meets the design requirements. After the inspection is qualified, firmly weld the fixing plate 5 and the mounting plate 4, and the fixing plate 5 and the guide tube 3.

[0028] The mounting plate 4 has 7 bolt holes with the same diameter and spacing as the steel structure column 1. The number of bolt holes can be selected according to the weight of the module. The guides must be used in pairs, but for ease of use, the upper guide and the lower guide have completely identical parameters and can be interchanged.

[0029] One end of the guide pin 2 is a tapered end 22, and the other end is a flat end 23. The radial dimension of the guide pin 2 at the lower end of the locking section is equal to the inner diameter of the guide tube 3, so that the flat end 23 of the guide pin 2 can be firmly inserted into the guide tube 3. The length of the tapered end 22 of the guide pin 2 is greater than the length of the guide tube 3, so as to have sufficient insertion length.

[0030] The guide pin 2 includes a first plate 24 and a second plate 25. The first plate 24 and the second plate 25 have a locking portion 21 in the middle with a width greater than the inner diameter of the guide tube 3. The first plate 24 and the second plate 25 each have an opening 6 from the end to the locking portion 21. The first plate 24 and the second plate 25 are vertically inserted through the opening 6 to form the guide pin 2, and the two locking portions 21 form the locking section.

[0031] Both the first plate 24 and the second plate 25 have a tapered end 22. The opening 6 of the first plate 24 is located at the tapered end 22, and the opening 6 of the second plate 25 is located at the other end opposite to the tapered end 22.

[0032] After the first plate 24 and the second plate 25 are inserted through the opening 6, the opening 6 and the joint 26 of the plate are welded and fixed.

[0033] The plate body can be a thin strip steel plate, that is, each guide pin 2 is formed by inserting two plates with an opening 6 at one end. After insertion, the joint between the guide pin 2 and the opening 6 is reinforced by simple spot welding. After reinforcement, a guide tube 3 is used for simple testing. The guide pin 2 can move freely in the guide tube 3 and maintain a suitable gap with the guide tube 3. The size of the gap is designed according to the allowable deviation of the steel structure. In order to ensure the manufacturing accuracy of the guide pin 2, the size of the opening 6 should only be slightly larger than the thickness of the plate body. The guide pin 2 after insertion only needs to be reinforced by simple spot welding, which greatly reduces the deformation during the welding process and lays a good foundation for improving the installation accuracy of the steel structure module in the future.

[0034] The height of the locking segment is equal to the distance between the ports of the two adjacent guide tubes 3, thereby enabling the locking segment to support the two adjacent guide tubes 3.

[0035] During installation, the prepared guide is installed on the already installed steel structure column 1 using bolts 7 and nuts 8 via the mounting plate 4. The flat end 23 of the guide pin 2 is inserted into the guide tube 3 of the guide of one of the already installed steel structure columns 1. The same method is used to complete the installation of the guides for the other steel structure columns 1. Next, the steel structure modules that have passed the installation accuracy check are hoisted to the position above the steel structure column 1 to be installed using large hoisting machinery. After the guide pin 2 is roughly aligned with the opening of the guide tube 3, it is slowly lowered. Since the upper part of the guide pin 2 is a tapered end 22 that is thicker at the bottom and thinner at the top, even if the module installation position is not completely aligned or the accuracy of the steel structure module column changes due to hoisting deformation, under the combined action of the weight of the steel structure module and the lateral extrusion force of the vertical assembly of the steel structure module composed of the guide pin 2 and the guide on the auxiliary structure, the guide pin 2 is still accurately inserted into the adjacent guide tube 3, so that the steel structure module can be installed quickly and accurately in the design position.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
