Description

Technical Field

[0001] The utility model relates to the technical field of steel structure installation, in particular to a prefabricated steel structure for buildings. 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 and steel plates. It is widely used because of its light weight and simple construction.

[0003] The installation of prefabricated steel structure sheds requires the installation of a corresponding number of herringbone beams on the columns, and then the middle beam is fixed between the two adjacent herringbone beams. Currently, when building steel structure sheds, workers usually use bolts to fix the middle beam to the herringbone beams. The workers need to hold the middle beam in their hands and lift it up before tightening the bolts to fix it, which takes a lot of time and reduces the overall work efficiency to a certain extent. Utility Model Content

[0007] Preferably, the clamping block comprises a clamping portion and a flat plate portion fixed to each other, and the clamping portion is a triangular block with a triangular cross-section.

[0008] Preferably, one end of an adjustment plate is fixed to the side wall of the clamping block, and the other end of the adjustment plate passes through the fixing block and extends to the outside of the fixing block.

[0009] Preferably, one end of an adjustment plate is fixed to the side wall of the clamping block, and the other end of the adjustment plate passes through the fixing block and extends to the outside of the fixing block.

[0010] Preferably, the structure consisting of the clamping block, the spring, the accommodating groove and the adjusting plate is provided in two groups symmetrically about the central axis of the fixing block, and the inner wall of the middle beam is symmetrically provided with stop grooves.

[0011] Preferably, a guide plate is fixed to the inner wall of the herringbone beam, and the lower end surface of the middle beam can move along the upper end surface of the guide plate.

[0023] like Figure 1-4 As shown, a prefabricated steel structure for building includes a herringbone beam 10, which plays the most important supporting role in the prefabricated steel structure greenhouse. Two adjacent herringbone beams 10 are connected and fixed by an intermediate beam 11, and the herringbone beam 10 and the intermediate beam 11 are connected by a mounting mechanism 20;

[0024] The mounting mechanism 20 includes a fixing block 21 fixed on the herringbone beam 10. The fixing block 21 is a T-shaped block. The flat part of the fixing block 21 is fixed to the herringbone beam 10. The fixing block 21 is slidably matched with the middle beam 11. The protruding end of the fixing block 21 is provided with a receiving groove 22. A spring 23 is arranged in the receiving groove 22. A clamping block 24 is fixed to the end of the spring 23 away from the bottom of the groove. That is, one end of the spring 23 is fixed to the bottom of the groove, and the other end of the spring 23 is fixed to the clamping block 24. The clamping block 24 can be clamped in a stop groove 25. The stop groove 25 is provided on the inner wall of the middle beam 11. Specifically, the end of the middle beam 11 is in a "concave" shape. The fixing block 21 can be clamped in the concave part of the middle beam 11. The stop groove 25 is provided on the inner wall of the concave part of the middle beam 11.

[0025] As a further explanation of this embodiment, the clamping block 24 includes a clamping portion 241 and a flat plate portion 242 fixed to each other, and the clamping portion 241 is a triangular block with a triangular cross-section. Preferably, the clamping portion 241 is a triangular block with a right-angled triangle cross-section.

[0026] As a further explanation of this embodiment, one end of an adjustment plate 26 is fixed to the side wall of the clamping block 24 , and the other end of the adjustment plate 26 penetrates the fixing block 21 and extends to the outside of the fixing block 21 .

[0027] As a further explanation of this embodiment, the structure composed of the clamping block 24, the spring 23, the receiving groove 22 and the adjusting plate 26 is arranged in two groups symmetrically about the central axis of the fixing block 21, and two retaining grooves 25 are symmetrically opened on the inner wall of the recessed part of the middle beam 11. This arrangement can enhance the strength of the herringbone beam 10 and the middle beam 11 when clamped.

[0028] As a further explanation of this embodiment, a guide plate 40 is fixed on the inner wall of the herringbone beam 10, and the guide plate 40 is located above the fixed block 21. During installation, the lower end surface of the middle beam 11 first contacts the upper end surface of the guide plate 40, and then the middle beam 11 moves along the upper end surface of the guide plate 40, and the movement trajectory is consistent with the cross-section of the guide plate 40.

[0029] As a further explanation of this embodiment, in order to ensure that the constructed steel structure greenhouse is waterproof, the surfaces of the herringbone beam 10 and the middle beam 11 are coated with anti-rust paint.

[0030] During installation, first place the middle beam 11 in the middle of the herringbone beam 10, and the middle beam 11 first overlaps with the guide plate 40, and then pushes the herringbone beam 10 toward the end thereof until the fixing block 21 on the guide plate 40 engages with the depression in the middle of the herringbone beam 10, and then the inclined surface of the engaging portion 241 of the clamping block 24 overlaps with the depression in the middle of the herringbone beam 10, at which time the spring 23 is in a compressed state, until the clamping block 24 is aligned with the retaining groove 25, the spring 23 resets and pushes the clamping block 24 to engage with the retaining groove 25, and the installation of the middle beam 11 is completed.

[0031] When the middle beam 11 needs to be disassembled, the adjusting plate 26 is manually moved, and the adjusting plate 26 drives the block 24 to move away from the retaining groove 25 until the block 24 is completely separated from the retaining groove 25. At this time, the middle beam 11 can be separated from the herringbone beam 10.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model.
