Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a connection structure of vestibule, including concrete wall 1 and vestibule 2, concrete wall 1's lateral wall is fixed with steel corbel 11, and steel corbel 11 top is installed to vestibule 2's one end.

The steel corbel 11 is towards a side face fixedly connected with mounting panel 111 of concrete wall 1, and mounting panel 111 is fixed at the lateral wall of concrete wall 1 through multiunit crab-bolt 112, and inside crab-bolt 112 penetrated the mounting panel 111 and squeezed into concrete wall 1, fixed steel corbel 11 at the lateral wall of concrete wall 1. A plurality of reinforcing rib plates 113 are fixed between the bottom surface of the steel corbel 11 and the mounting plate 111, the reinforcing rib plates 113 reinforce the supporting force of the steel corbel 11 and simultaneously reinforce the connection between the steel corbel 11 and the mounting plate 111.

Referring to fig. 1 and 2, two sets of connecting components 3 are fixed with at 11 tops of steel corbel, and two sets of connecting components 3 set up along the length direction of vestibule 2 in an arrangement. The connecting assembly 3 comprises a rotating rod 32 and two connecting screw rods 31, and the two connecting screw rods 31 are arranged in the direction perpendicular to the length of the corridor 2. The corridor 2 is provided with arc-shaped holes 21 corresponding to the connecting screw rods 31, the diameters of the arc-shaped holes 21 are equal to the length of the rotating rods 32, and the end parts of the two arc-shaped holes 21 corresponding to the same group of connecting screw rods 31 are close to each other. The guide screw 211 corresponding to the connecting screw 31 penetrates through the arc-shaped hole 21, the guide screw 211 is located on one side of the corresponding connecting screw 31, which is back to the other connecting screw 31 in the same group, two ends of the rotating rod 32 are respectively sleeved on the side walls of the corresponding connecting screw 31 and the guide screw 211, nuts 311 are respectively fixed on the upper side and the lower side of the end portion of the rotating rod 32 of the side walls of the guide screw 211 and the connecting screw 31, and the upper nut 311 and the lower nut 311 are respectively tightly abutted on the upper side and the lower side of the rotating rod 32.

The lead screw 211 and the connecting screw 31 are fixed to each other in the vertical direction by the rotating rod 32, thereby fixing the gallery 2 above the steel corbel 11. When vestibule 2 received great non-resistible power, bull stick 32 can rotate in the horizontal direction with the skew of cooperation vestibule 2, bull stick 32's length is fixed to make lead screw 211 remove in order to cooperate the skew of vestibule 2 in arc hole 21, vestibule 2 can take place the skew at 360 degrees on the horizontal direction, can avoid vestibule 2 to receive when non-resistible power such as earthquake and produce with both sides building and pull or warp, thereby avoid making vestibule 2 take place to drop, collapse the phenomenon.

The top surface middle part of steel corbel 11 is fixed with support seat 4 that supports 2 bottom surfaces of vestibule, and a plurality of balls 41 are installed in the top surface rotation of support seat 4, and ball 41 and the mutual butt of 2 bottom surfaces of vestibule. The ball 41 reduces the coefficient of friction between the support seat 4 and the gallery 2, facilitating the offset of the gallery 2 on the support seat 4. Four sides that 2 bottoms surfaces of vestibule are close to supporting seat 4 all are fixed with stopper 22, and the height that highly is less than the top of supporting seat 4 of stopper 22 bottom leaves the interval between stopper 22 and the 4 lateral walls of corresponding supporting seat. Arc length in arc hole 21 and bull stick 32 all are fixed, and vestibule 2 skew range is too big, makes arc hole 21 and bull stick 32 receive great effort of dragging easily to the production is defective, and stopper 22 blocks at four lateral walls of supporting seat 4, prescribes a limit to vestibule 2's displacement, can disperse the effort that arc hole 21 and bull stick 32 received, reduces defective production.

Referring to fig. 1, vestibule 2 extends horizontally access board 23 towards concrete wall 1's lateral wall top, and horizontal mesa 12 has been seted up at concrete wall 1 top, and access board 23's bottom surface and horizontal mesa 12 butt each other, and access board 23 keeps away from 2 one ends of vestibule and is greater than the interval between stopper 22 to the corresponding supporting seat 4 lateral walls to the interval between the lateral wall of concrete wall 1. The butt strap 23 is connected with the horizontal table-board 12 of concrete wall 1 all the time when the vestibule 2 moves, can avoid the vestibule 2 and concrete wall 1 to produce the breach in the junction when squinting, cause the potential safety hazard. Powerful spring 24 is installed to the below that the vestibule 2 lateral wall is located access board 23, and powerful spring 24 keeps away from vestibule 2's one end and concrete wall 1's lateral wall fixed connection. Powerful spring 24 can avoid vestibule 2 to take place direct collision with concrete wall 1 when squinting, and powerful spring 24 takes place deformation simultaneously and can provide cushioning effect, reduces vestibule 2's skew range.

The implementation principle of the embodiment is as follows: connecting screw 31 and lead screw 211 are fixed each other in vertical direction, can fix vestibule 2 on steel corbel 11, and supporting seat 4 supports vestibule 2 bottom surface. When the corridor 2 is subjected to irresistible acting force such as earthquake, wind load and the like, the rotating rod 32 rotates around the connecting screw rod 31 to match the deviation of the corridor 2; since the length of the rotating rod 32 is fixed, the lead screw 211 moves within the arc-shaped hole 21 to match the offset of the vestibule 2. The vestibule 2 can be shifted by 360 degrees in the horizontal direction, and the bottom surface of the vestibule 2 slides on the ball 41, so that the friction force between the vestibule 2 and the support seat 4 can be reduced. This structure makes vestibule 2 not form connection structure with the building main part of both sides, can reduce the destruction that effort such as earthquake produced vestibule 2, and vestibule 2 is difficult to take place to drag or warp with concrete wall 1's hookup location, avoids taking place vestibule 2 obscission.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
