Detailed Description

The present invention is described in detail below with reference to the drawings, which are intended to illustrate preferred embodiments of the present invention and not to limit the scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the purpose of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation configuration and operation, and thus, should not be construed as limiting the present invention.

The utility model provides a ppvc space module side wall connecting piece, as shown in figure 4, includes steel pull ring 11, integrated into one piece in the first power consumption steel sheet 8 of steel pull ring tail end, locate the second power consumption steel sheet 9 of first power consumption steel sheet 8 rear side and connect the connecting steel plate 10 between first power consumption steel sheet 8 and second power consumption steel sheet 9. Except that the pull ring part is exposed in the longitudinal connecting groove 7 preset on the side wall, the rest parts are all pre-embedded in the side wall, when the side wall is vibrated, the first energy consumption steel plate 8 and the second energy consumption steel plate 9 consume energy in sequence, the effect of second-order energy consumption is achieved, and the influence of vibration on the ppvc space module can be effectively reduced.

As shown in fig. 4, the first energy consumption steel plate 8 and the second energy consumption steel plate 9 are both embedded in the side wall, and the steel pull ring 11 is partially exposed and extends out of the connecting groove 7 preset in the side wall along the horizontal direction.

As shown in fig. 2 and 4, the width of the exposed part of the steel tab 11 matches the width of the connecting slot 7. Thus avoiding empty insertion when inserting the longitudinal steel bar (namely, the longitudinal steel bar is inserted outside the steel pull ring and cannot play a role in connection)

As shown in fig. 1, 2, 3 and 4, when the first wall 1 and the second wall 2 of 2 space modules are butted, 2 opposite steel pull rings 11 are overlapped in 2 opposite connecting grooves 7, and the inner hole of the overlapped part of the 2 steel pull rings 11 is sized to accommodate 2 longitudinal steel bars with the diameter of 14 mm.

As shown in fig. 3, the connector further comprises 2 longitudinal bars, and the bottom of the longitudinal bar 5 at the upper layer is inserted into the plurality of steel tabs 11 at the top of the lower layer and is overlapped with the upper part of the longitudinal bar 6 at the lower layer.

As shown in fig. 3, the lower portion of the upper longitudinal reinforcement 5 overlaps with the portion of the lower longitudinal reinforcement 6 having a height of 2/3 or more. The purpose of the overlap joint is to improve the connection strength between the upper and lower layer space modules.

As shown in fig. 4, the stiffness of the first dissipative steel sheet 8 is less than the stiffness of the second dissipative steel sheet 9. The second-order energy consumption enhancing effect can be achieved through the arrangement, under the condition of small earthquake, the first energy consumption steel plate 8 acts, the earthquake intensity is increased, the second energy consumption steel plate 9 participates in earthquake resistance, and damage to the space module due to the earthquake is further avoided.
