However, the present invention may be practiced in other ways than those specifically described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0034] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure are enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0035] Referring to Figure 1-8 , an embodiment of the present invention provides a steel structure column head connection member, including the following parts:

[0036] A base, which is at least composed of a base 1, a top seat 2, and a first stress-bearing wall 3 integrally connected between the two. The base 1 is horizontally square-shaped, and its four side edges are defined as four installation areas here. The number of the first stress-bearing walls 3 is four, which are respectively located at the four installation areas. A second stress-bearing wall 4 corresponding to the first stress-bearing wall 3 is also movably connected on the base 1, and it is also located in the four installation areas. As Figure 5 shown, the other end of the second stress-bearing wall 4 in each installation area is rotatably connected to the first stress-bearing wall 3 in the opposite installation area, which is beneficial to ensuring the stability of the first stress-bearing wall 3 within the movable range. An embedding groove 5 for accommodating a Bailey beam is formed between the first stress-bearing wall 3 and the second stress-bearing wall 4 in each installation area, so there are four corresponding ones;

[0037] An insertion end 6, which is a column head-like structure and is used to be inserted into the pin hole at the end of the Bailey beam. A plurality of insertion ends 6 are slidably arranged on each second stress-bearing wall 4, and the specific number is determined according to the number of pin holes at the end of the Bailey beam;

[0038] A driving part, the number of which corresponds to the embedding groove 5. The insertion end 6 on each second stress-bearing wall 4 is slidably controlled by a driving part;

[0039] During the installation process of the present invention in cooperation with the Bailey beam, by fixedly connecting the base 1 to the ground support part, when connecting multiple Bailey beams, the end parts of the Bailey beams are respectively inserted into the corresponding embedding grooves 5, and by operating the driving part to control the movement of the insertion end 6, the insertion end 6 is inserted into the pin hole of the Bailey beam, thereby restricting the Bailey beam to realize the installation of the present invention and the Bailey beam, and thus completing the connection at the node between multiple Bailey beams.

[0040] Further, referring to Figure 2 , regarding the working mode of the driving part, specifically, the driving part includes a driving rod 7 which is rotationally matched with the base 1 and the top seat 2, and further includes a push block 8 slidably arranged on the first stress wall 3 which is in threaded cooperation with the driving rod 7. A return spring 9 is connected between the insertion end 6 and the second stress wall 4 to keep the insertion end 6 in a state of leaving the embedding groove 5 in the normal state. The tail of the insertion end 6 is constructed with a wedge-shaped inclined surface 10. By rotating the driving rod 7 to drive the push block 8 to move, the push block 8 will push the insertion end 6 into the embedding groove 5 through the inclined surface 10, thereby locking the Bailey beam. When the driving rod 7 controls the push block 8 to leave the inclined surface 10, the insertion end 6 leaves the embedding groove 5, making the Bailey beam detachable.

[0041] Further, referring to Figure 3-7 , regarding the stability maintenance of the second stress wall 4, specifically, a connecting column is further connected to the first stress wall 3. The connecting column is composed of a stress plate 11, a connecting rib 12 and a column body 13 which are connected. The other end of the column body 13 is further constructed with two clamping plates 14. A stress detection element 15 (pressure strain gauge) for detecting the extrusion force is arranged on the first stress wall 3. The stress plate 11 is embedded in the first stress wall 3, and the pressure strain gauge abuts between the stress plate 11 and the first stress wall 3. A through hole 16 is penetrated and constructed on the second stress wall 4, and its diameter is larger than that of the column body 13. The column body 13 on the first stress wall 3 in each installation area passes through the through hole 16 on the second stress wall 4 in the adjacent installation area, and the two clamping plates 14 abut on both sides of the second stress wall 4. Through the connection of the connecting column, the second stress wall 4 is supported by the first stress wall 3 in the adjacent installation area to maintain the stability of the second stress wall 4. The cooperation of the pressure detection element enables the detection of the tilting force of the second stress wall 4 when there is a tendency of side tilt, so as to facilitate observing the lateral stress condition of the Bailey beam at all times.

[0042] Further, referring to Figure 5 and Figure 6, Regarding the connection method between the second force-bearing wall 4 and the base 1, specifically, a hook block 17 is constructed on the base 1. The bottom end of the second force-bearing wall 4 is restricted on the base 1 by the hook block 17 and cannot be separated. Moreover, a shock-absorbing pad 18 is abutted between the bottom end of the second force-bearing wall 4 and the base 1. The gravity of the Bailey beam will fall on the second force-bearing wall 4 through the insertion end 6 and finally on the shock-absorbing pad 18. Through the function of the shock-absorbing pad 18, when the Bailey beam is vibrating, the transmission of vibration to the base 1 can be reduced, thereby reducing the transmission to the supporting part and also reducing the transmission to other Bailey beams.

[0043] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine task of design, manufacturing, and production.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
