Embodiment 1

[0031] This embodiment is basically as figure 1 and figure 2 Shown: the connecting structure used for assembled building components, including an annular sleeve 1 sleeved on the outer periphery of the building component, the annular sleeve 1 includes a left half body 101 and a right half body 102, two parts of the left half body 101 and the right half body 102 The ends are integrally formed with ear plates 2, and the ear plates 2 are provided with installation holes. In this embodiment, the user puts the left half body 101 and the right half body 102 respectively on the outer periphery of the upper building component 11, uses bolts to pass through the installation holes, and then tightens the nuts on the bolts, so that the left half body 101 and the right half body 101 and the right half body The half body 102 is fixedly socketed on the outer periphery of the building component, so that the ring sleeve 1 is fixedly socketed on the outer periphery of the building component. ...

Embodiment 2

[0039] The difference between this embodiment and the first embodiment is: image 3 As shown, the annular sleeve 1 is provided with a plurality of horizontally arranged threaded holes along the circumferential direction, and the threaded holes are threadedly connected with a pressing threaded rod 13 . In this embodiment, the number of threaded holes is six.

[0040] In this embodiment, since the annular sleeve 1 has six threaded holes and abutting threaded rods 13 in the circumferential direction, the threaded rods 13 are rotated and the ends of the abutting threaded rods 13 are abutted against the outer peripheral wall of the building component. The annular sleeve 1 is fixedly sleeved on building components of different sizes to achieve alignment of building components of different sizes. In addition, the connection structure in this embodiment can also be applied to building components whose radial cross section is rectangular, thereby expanding the application range of the...

Embodiment 3

[0042] The difference between this embodiment and the second embodiment is: Figure 4 As shown, among the six threaded holes, four threaded holes are selected as special threaded holes, and the abutment threaded rod 13 corresponding to the special threaded hole is a special abutment threaded rod 14 . Among the four special threaded holes, the included angle between two adjacent special threaded holes is 90°, and the rotation directions of the opposite two special threaded holes are opposite. A telescopic rod 15 is coaxially connected to the end of each special abutting threaded rod 14. The telescopic rod 15 includes an outer rod 151 and an inner rod 152 that can slide in the axial direction. A plurality of grooves, the inner rod 152 is axially provided with a plurality of sliding bars which are matched with the grooves, and the sliding bars are slidably connected in the grooves.

[0043] The inner rod 152 is welded with the end of the special abutting threaded rod 14 , the ou...

Abstract

The invention relates to the field of building construction, and discloses a connecting structure for a fabricated building component. The connecting structure comprises an annular sleeve sleeving theperiphery of the building component, the bottom of the annular sleeve is fixedly connected with a cylinder, the peripheral wall of the cylinder is in threaded connection with a limiting cylinder, theinner diameter of the bottom of the limiting cylinder is gradually reduced in the direction away from the annular sleeve, a plurality of limiting rods sliding in the radial direction are arranged atthe bottom of the annular sleeve, the bottom ends of the limiting rods extend out of the limiting cylinder, wedge-shaped blocks are fixedly connected to the limiting rods, and the wedge faces of the wedge-shaped blocks make contact with the inner wall of the bottom of the limiting cylinder. According to the connecting structure, the two to-be-welded building components can be rapidly aligned, stagger welding is avoided, therefore the problem that the bearing capacity is reduced due to the stagger welding is avoided, and the device is simple in structure and convenient to use in a constructionsite.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a connection structure for assembled building components. Background technique [0002] At present, domestic and foreign prefabricated buildings mainly include three types: prefabricated concrete prefabricated buildings, steel structure prefabricated buildings and wooden prefabricated buildings. Among them, the connection of steel structure assembly building components is mainly welding and steel column planing and top-tight connection. Before welding the prefabricated steel structure components, it is necessary to align the two prefabricated steel structure components to be welded. However, due to the limited conditions on the construction site, it is usually to rely on the construction experience of the workers to align and weld the two steel structure assembly building components, but this will easily lead to misplaced welding of the two steel structure assembly building ...
