[0029] Embodiment 1:

[0030] Reference Figure 1 and Figure 3 ​The embodiment provides a connecting structure 1 between modular building structures, which comprises an upper plug-in part 11, a connecting part 13 and a lower plug-in part 12 from top to bottom, the upper plug-in part 11 is arranged in the lower end of a first to-be-connected part 213, the lower plug-in part 12 is arranged in the upper end of a second to-be-connected part 313, the connecting part 13 is connected between the lower end of the upper plug-in part 11 and the upper end of the lower plug-in part 12, the upper surface of the connecting part 13 is clamped to the lower end of the first to-be-connected part 213, the lower surface of the connecting part 13 is used for clamping the upper end of the second to-be-connected part 313, so as to prevent the upper plug-in part 11 and the lower plug-in part 12 from moving up and down, meanwhile, the connecting part 13 supports the end of the first to-be-connected part 213 and the second to-be-connected part 313, in addition, in order to ensure the neatness of the connecting point, the outer edge of the connecting part 13 is flush with the outer edge of the end of the first to-be-connected part 213 and the second to-be-connected part 313 in the vertical direction, in order to further enhance the connecting strength of the whole, the upper plug-in part 11 and the lower plug-in part 12 are both provided with flow-through channels which are communicated with the internal space of the first to-be-connected part 213 and the second to-be-connected part 313, the flow-through channels of the two are communicated in the vertical direction, so as to fill the internal space of the first to-be-connected part 213 and the second to-be-connected part 313 with a reinforcing medium from top to bottom at one time, the reinforcing medium can be concrete slurry or other materials which can realize the reinforcing effect by the solidification process. In this way, the first to-be-connected part 213 and the second to-be-connected part 313 are connected together under the interaction of the reinforcing medium and the whole connecting structure 1, the tensile stress resistance of the connecting node of the two adjacent to-be-connected parts 13 is improved, the secondary opening can be avoided, the overall structural performance of the building structure is improved, and the connecting mode is simplified.

[0031] Referring to Figure 1 and Figure 3 , in order to make the connecting structure 1 bear force uniformly from top to bottom, further improve the tensile stress resistance of the whole, meanwhile, improve the accuracy and efficiency of the abutting process of the first to-be-connected part 213 and the second to-be-connected part 313, the lower plug-in part 12 is centrally symmetric with the upper plug-in part 11, the structure of the upper plug-in part 11 is introduced in detail, the specific structure of the lower plug-in part 12 is referred to the upper plug-in part 11, and details are not repeated here.

[0032] The upper plug-in 11 comprises a first supporting part 111 and a first positioning part 112. The first supporting part 111 is arranged above the connecting piece 13 in the vertical direction, and is used to form a support in the vertical direction. The first positioning part 112 is connected to the first supporting part 111 at one end, and is connected to the upper part of the connecting piece 13 at the other end. The outer side surface of the first positioning part 112 forms a first preset angle c with the vertical direction. The first positioning part can limit the first to-be-connected piece 213 in the first direction a. When the first to-be-connected piece 213 falls along the first supporting part 111 to the first positioning part 112, and continues to slide downward along the outer side surface of the first positioning part 112 to the connecting piece 13, the outer edge of the lower end of the first positioning part contacts one edge of the lower end of the first to-be-connected piece 213. In this way, the position of the first to-be-connected piece 213 in the first direction a is limited. The first preset angle c is selected to be 1-89°, and is preferably 30-60°.

[0033] With reference to Figure 1 and Figure 3 In order to further improve the accuracy and efficiency of the docking process of the first to-be-connected piece 213 and the second to-be-connected piece 313, the position of the first to-be-connected piece 213 in the second direction b perpendicular to the first direction a in the horizontal plane is limited. The second positioning part 113 is arranged on different sides of the upper plug-in 11. The second positioning part 113 is connected to the first supporting part 111 at one end, and is connected to the upper part of the connecting piece 13 at the other end. The outer side surface of the second positioning part 113 forms a second preset angle d with the vertical direction. When the first to-be-connected piece 213 falls along the first supporting part 111 to the first positioning part 112 and the second positioning part 113, and continues to slide downward along the outer side surface of the first positioning part 112 and the outer side surface of the second positioning part 113 to the connecting piece 13, the outer edge of the lower end of the first positioning part 112 and the outer edge of the lower end of the second positioning part 113 simultaneously contact two adjacent edges of the lower end of the first to-be-connected piece 213. In this way, the position of the first to-be-connected piece 213 in the first direction a and the second direction b is limited, that is, the specific position of the first to-be-connected piece 213 on the connecting piece 13 is limited. The second preset angle d is selected to be 1-89°, and is preferably 30-60°. In addition, in order to facilitate the downward positioning process of the first to-be-connected piece 213, the outer side surface of the first positioning part 112 and the outer side surface of the second positioning part 113 are connected at the highest point of the first supporting part 111, that is, the first to-be-connected piece 213 simultaneously slides downward along the outer side surface of the first positioning part 112 and the outer side surface of the second positioning part 113.

[0034] With reference to Figure 1 and Figure 3In order to further improve the accuracy and efficiency of the docking process of the first to-be-connected part 213 and the second to-be-connected part 313, facilitate accurate positioning of the first to-be-connected part 213 by the first positioning part 112 and the second positioning part 113, the upper insert part 11 further comprises a third positioning part 114, which is arranged on the upper end of the first supporting part 111. The third positioning part 114 comprises a first plate body 1141 and a second plate body 1142, and the first plate body 1141, the second plate body 1142 and the first supporting part 111 form a triangle. The first plate body 1141 supports the second plate body 1142, the outer side of the second plate body 1142 extends outward in the direction of the connecting part 13, and the second plate body 1142 is arranged at a third preset angle e with the vertical direction. In this way, the first to-be-connected part 213 starts to slide downward along the outer side of the second plate body 1142 when it contacts the upper end of the first supporting part 111. Since the third positioning part 114 is arranged on the opposite side of the first positioning part 112, the third positioning part 114 can guide the first to-be-connected part 213 to be positioned in the first positioning part 112. The third preset angle e is selected to be 1-89°, preferably 30-60°. At the same time, the triangle formed by the first plate body 1141, the second plate body 1142 and the upper part of the first supporting part 111 is geometrically stable, ensuring that after the reinforcing medium is added, the reinforcing medium and the third positioning part 114 are in contact to form a good anti-pulling effect. In order to better realize the anti-pulling effect, the first plate body 1141 is arranged horizontally, that is, perpendicular to the pulling direction. Under the cooperation of the lower insert part 12 and the upper insert part 11, the anti-pulling effect can be realized to the maximum extent.

[0035] Referring to Figure 1 and Figure 3In order to further improve the accuracy and efficiency of the docking process of the first to-be-connected part 213 and the second to-be-connected part 313, and facilitate accurate positioning of the first to-be-connected part 213 by the first positioning part 112 and the second positioning part 113, the upper insert part 11 further comprises a fourth positioning part 115, which is arranged on the upper end of the first supporting part 111. The fourth positioning part 115 comprises a third plate body 1151 and a fourth plate body 1152, and the third plate body 1151, the fourth plate body 1152 and the upper part of the first supporting part 111 form a triangle. The third plate body 1151 supports the fourth plate body 1152, and the outer side of the fourth plate body 1152 extends outward in the direction of the connecting part 13, and the fourth plate body 1152 is arranged at a fourth preset angle f with the vertical direction. In this way, the first to-be-connected part 213 starts to contact the upper end of the first supporting part 111 and simultaneously slides downward along the outer side of the second plate body 1142 and the outer side of the fourth plate body 1152. Because the fourth positioning part 115 is arranged on the opposite side of the second positioning part 113, the fourth positioning part 115 can guide the first to-be-connected part 213 to be positioned in the second positioning part 113. The fourth preset angle f is selected to be 1-89°, preferably 30-60°. The fourth positioning part 115 forms a stable triangular structure with the first supporting part 111, which is consistent with the action of the third positioning part 114, and will not be described in detail here. Under the cooperation of the first positioning part 112, the second positioning part 113, the third positioning part 114 and the fourth positioning part 115, the first to-be-connected part 213 and the second to-be-connected part 313 can be quickly and accurately docked, improving the installation efficiency.

[0036] In addition, the sizes of the first positioning part 112 and the second positioning part 113 are slightly smaller than the sizes of the corresponding edges of the first to-be-connected part 213, so that there is still adjustable construction space when the first to-be-connected part 213 has machining errors, and the lower insert part 12 is also processed similarly.

[0037] Referring to Figure 2 In order to improve the stability of the entire connecting structure 1, the connecting part 13 is arranged as a connecting plate 131, and the connecting plate 131 is provided with a through hole 132. The upper insert part 11 is connected to the upper part of the connecting plate 131, the lower insert part 12 is connected to the lower part of the connecting plate 131, and the through hole 132 communicates the upper insert part 11 and the lower insert part 12. The number of through holes 132 can be set to an indefinite number according to the injection needs, for example, Figure 2As shown, in order to avoid the first support part 111 of the I-shaped steel, four through holes 132 are arranged on the connecting plate 131. The shape of the connecting plate 131 is consistent with the projection shape of the first to-be-connected part 213 and the connecting part 13 to the connecting plate 131, so that the connection of the first to-be-connected part 213 and the second to-be-connected part 313 is more flat and beautiful; the first support part 111 can be selected from I-shaped steel or square steel. When the I-shaped steel is selected, the groove of the I-shaped steel extends in the vertical direction to form a flow-through channel, which facilitates the filling of the reinforcing medium from top to bottom; when the square steel is selected, the hollow area of the square steel extends in the vertical direction to form a flow-through channel; the selection of I-shaped steel or square steel can meet the supporting and upper and lower communication functions. In addition, the selection of the material of the upper insert 11 and the lower insert 12 is determined according to the stress requirements between different modular building structures.
