Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building envelopes, in particular to a connecting structure for building envelope nodes of an assembled steel structure building. Background Technique
[0002] An assembled steel structure building refers to a building that uses a framework of steel structure beams and steel structure columns as the main load-bearing structure, is equipped with peripheral enclosure wall panels as the peripheral enclosure system, and is supplemented with components such as equipment systems and interior decoration systems. It is designed and constructed using an integrated method. After the main construction of the assembled steel structure is completed, it is necessary to install enclosure wall panels on the outer wall of the steel structure. The function of the enclosure wall panels is to improve the aesthetics, fire prevention, and moth prevention of the overall building.
[0003] In order to facilitate the installation of the steel structure peripheral enclosure by installers, the prior art has made many improvements to the connecting structure of the steel structure building enclosure. For example, the patent with the publication number CN220521645U discloses an assembled enclosure structure for a steel structure residence, including a thermal insulation board. A protective steel plate is arranged on the outer side of the thermal insulation board. A first waterproof sealing plate is fixedly installed on the outer surface of one side of the upper end of the thermal insulation board, and a second waterproof sealing plate is fixedly installed on the outer surface of one side of the lower end of the thermal insulation board. A through hole is arranged on the first waterproof sealing plate, and a connecting bolt is installed inside the through hole. The connecting bolt can fasten the first waterproof sealing plate to the steel structure. This utility model simplifies the installation structure of the enclosure wall panels. During the construction process, only the same enclosure structures need to be inserted together to complete the assembly, reducing the assembly time and improving the work efficiency. It can effectively accelerate the overall construction progress of the steel structure residence and also improve the versatility of the enclosure structure.
[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:
[0005] In the above comparative document, the first protective steel plate is installed through a connecting bolt, and the second protective steel plate is inserted through a tenon structure during installation. As time goes by after the protective steel plate is installed, the outside of the protective steel plate will be damaged due to being impacted or eroded. Therefore, it is necessary to replace and maintain the damaged protective steel plate. After installing the enclosure through the above comparative document, if a certain damaged protective steel plate needs to be disassembled, replaced, and maintained in the later stage, due to the tenon structure restricting both the front and back of the protective steel plate, it is necessary to disassemble all the surrounding protective steel plates, thereby increasing the cost of later maintenance. Therefore, there is an urgent need in the field to improve the connecting structure of building envelope nodes of assembled steel structure buildings to solve the defects of the prior art. Content of the Utility Model
[0006] Aiming at the deficiencies of the prior art, the utility model provides a connecting structure for the enclosure nodes of an assembled steel structure building, which is relatively convenient to install and easy to maintain in the later stage, thereby reducing the later installation cost.

Symmetric clamping grooves adapted to the clamping column are formed through the clamping piece.
[0009] Preferably, bump points are fixedly connected to the side walls of the clamping grooves, and the bump points are used to limit the clamping column.
[0010] Preferably, a stepped hole communicating with the through hole is formed on the side of the protective steel plate away from the installation substrate, and a rubber plug is threadedly connected in the stepped hole.
[0011] Preferably, the friction coefficient between the rotating seat and the bottom of the installation groove is greater than the self-weight of the installation substrate, and a clamping platform is formed on the side surface of the rotating seat.

A first clamping groove adapted to the first reinforcing rib is formed on the side of the installation substrate close to the fireproof and heat-insulating board. A second reinforcing rib is fixedly connected to the side of the protective steel plate close to the fireproof and heat-insulating board. A second clamping groove adapted to the second reinforcing rib is formed on the side of the fireproof and heat-insulating board close to the protective steel plate.
[0013] Preferably, an anti-rust coating is sprayed on the side of the protective steel plate away from the fireproof and heat-insulating board, and the rubber plug has a sealing effect and is made of a corrosion-resistant material.
[0014] In view of the deficiencies of the prior art, the present utility model provides a connecting structure for the enclosure nodes of an assembled steel structure building, overcoming the deficiencies of the prior art. The beneficial effects of the present utility model are as follows:

A fireproof and heat-insulating board 2 is provided between the installation base plate 3 and the protective steel plate 1. Installation grooves 4 communicating with the outside are formed on the side surfaces of the installation base plate 3. Installation holes 9 communicating with the installation grooves 4 are formed on the side of the installation base plate 3 away from the protective steel plate 1. Through holes 5 communicating with the installation grooves 4 are formed through the protective steel plate 1, the fireproof and heat-insulating board 2, and the installation base plate 3. An installation bolt 6 with one end passing through the installation hole 9 is provided in the installation groove 4. A fastening bolt 7 passes through the through hole 5. The fastening bolt 7 is used to connect the installation base plate 3, the fireproof and heat-insulating board 2, and the protective steel plate 1 in sequence. A threaded hole 8 adapted to one end of the fastening bolt 7 is formed at one end of the installation bolt 6. An auxiliary connection unit 10 is provided between two adjacent installation grooves 4. The auxiliary connection unit 10 is used to limit and pre-fix between two adjacent installation base plates 3.
[0030] Specific implementation method in this embodiment: Measure the position where the protective steel plate 1 is to be installed, make a horizontal mark on the side of the steel structure to be enclosed, align the side of the installation substrate 3 with the horizontal line, pass one end of the installation bolt 6 through the installation hole 9, and connect one end of the installation bolt 6 to the steel structure. After installing the installation substrate 3, then install the adjacent installation substrates 3. Pre-fix the adjacent installation substrates 3 through the auxiliary connection unit 10, and all use the installation bolts 6 for installation and fixation. After installing the installation substrate 3, stick the fireproof insulation board 2 and the protective steel plate 1 to one side of the installation substrate 3 in sequence, align the through holes 5, pass one end of the fastening bolt 7 into the through hole 5, and thread it with the threaded hole 8 on the installation bolt 6. Tighten the fastening bolt 7 to fix the protective steel plate 1 and the fireproof insulation board 2 on the installation substrate 3. When it is necessary to replace a certain protective steel plate 1, just unscrew the fastening bolt 7 to replace the protective steel plate 1.
