Description

POSITIONING CONNECTING DEVICE AND BUILDING MODULE DEVICE

1ECHNICAL FIELD

[0001] The present disclosure relates to the technical field of assembled-type steel-structure constructing, and particularly relates to a positioning and connecting device and a construction-module device

BACKGROUND

[0002] Case-type module constructions are one of assembled-type steel-structure constructions. Because their construction modules can be pre-assembled in the factory and be stacked in the project site to complete the construction project, case-type module constructions have the characteristics of a high prefabrication degree, a small workload in the construction site, a short construction period and so on. The manufacturing deviations of the construction modules and the stacking errors in the project site have always been key factors that restrict the development of case-type module constructions. Currently, because aspects of construction projects such as the interior decoration, the exterior curtain wall and the conjunctions raise high requirements on the installation precision, how to improve the positioning precision between construction modules in construction projects has become a problem of case-type module constructions that is urgently needed to be solved. However, because of the technical limitations raised by the current construction-module positioning structures, it is difficult for the positioning structures in the prior art to satisfy the positioning precision required by con structi on proj ects.

[0003] In the prior art, although the influence by stacking errors on the positioning precision of construction modules can be reduced, the influence by manufacturing deviations on the positioning precision of construction modules cannot be prevented. For example, the positioning structure between construction modules of the patent application with the publication number of CN104179254A and the title of AUTOMATIC STACKING AND POSITIONING SYS IENI FOR MODULE-TYPE CONSTRUCTION MODULES AND CONNECTING METHOD THEREOF can reduce the influence by stacking errors on the positioning precision of construction modules during the stacking of the construction modules.

As shown in Fig. 1, a construction-module positioning system in the prior art comprises four connectors that are fixedly connected to the bottom of an upper-layer construction module (at least one two-directionally positioning connector 1, at least one one-directionally positioning and one-directionally guiding connector 2 and at least one double-bevel guiding connector 3), and four square tubes that are fixedly connected to the top of a lower-layer construction module and are provided correspondingly to the four connectors. The positioning and stacking of the upper-layer construction module and the lower-layer construction module is completed by the cooperation between the four connectors at the bottom of the upper-layer construction module and the four square tubes at the top of the lower-layer construction module.

[0004] It can be known from the principle of the positioning structure of construction module in the prior art that, because all of the four connectors and the four square tubes are required to be fixedly connected to the construction modules, and their positioning precisions are the same as the manufacturing precision of the construction modules, the positioning structure of construction modules in the prior art cannot prevent the influence by manufacturing deviations of the construction modules on the positioning precision of the construction modules. Additionally, the current construction modules are mainly formed by welded steel structures and have relatively large sizes, which results in that the manufacturing precision of construction modules has become a major factor that influences the positioning precision of the construction modules. Therefore, in the prior art, if it is required to improve the positioning precision of construction modules, a very large cost has to be spent to improve the manufacturing precision of construction modules.

[0005] Therefore, it is required to provide a positioning and connecting device and a construction-module device, to at least partially solve the above problems of the prior art.

[00148] In the following description, a large quantity of particular details are given so as to provide a more thorough understanding of the present disclosure. However, it is apparent to a person skilled in the art that the present disclosure can be implemented without one or more of those details.

[00149] In order to thoroughly understand the present disclosure, detailed structures will be proposed in the following description, to explain the present disclosure. Apparently, the implementing of the present disclosure is not limited to the particular details that are well known by a person skilled in the art. The preferable embodiments of the present disclosure are in detail described as follows, but besides those detailed descriptions, the present disclosure can also have other embodiments, and should not be interpreted to be limited to the embodiments disclosed herein.

[00151] The ordinal numerals used in the present disclosure such as "first" and "second" are only for identification, and do not have any other meanings, for example a particular order. Furthermore, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component".

[00152] The particular embodiments of the present disclosure will be explained in further detail below by referring to the drawings. The drawings show the representative embodiments of the present disclosure, and do not limit the present disclosure [00153] As shown in Figs. 2 to 4, the present disclosure provides a construction-module device. The construction-module device comprises a positioning and connecting device 100 and a construction module 200. The construction module 200 may be a container, and may also be a construction or product of other structures. The positioning and connecting device 100 may be used to connect two construction modules that are vertically stacked, may also be used to connect two layers of the construction modules, for example two upper-layer construction modules and two lower-layer construction modules, and may also be used to connect the construction module to the ground.

[00154] The positioning and connecting device 100 comprises top reference plates and bottom reference plates 120. The top reference plates 110 are used to be connected to the top of the construction module 200 (referring to Fig. 15), and the bottom reference plates 120 are used to be connected to the bottom of the construction module 200. Although the illustrated embodiment merely shows one bottom corner portion of the construction module 200, it can be understood by referring to Figs. 13 and 15 that the top reference plates 110 are individually provided at the four top corner portions of the construction module 200, and the bottom reference plates 120 are individually provided at the four bottom corner portions of the construction module 200. The four top reference plates 110 correspond to the four bottom reference plates 120 one by one.

[00155] The positions where the top reference plates 110 and the bottom reference plates 120 are located may be defined as the top predetermined positions and the bottom predetermined positions respectively. The top predetermined position and the bottom predetermined position of each of the pairs of the corresponding top reference plates 110 and bottom reference plates 120 have the same horizontal coordinate position with respect to a predetermined reference point and are arranged vertically with respect to each other. Further, the projections of the top reference plate 110 and of the bottom reference plate 120 in the height direction of the construction module 200 coincide. It can be understood that the top predetermined positions and the bottom predetermined positions may be understood as fixed positions of the construction module 200, and are not deviated due to the manufacturing deviations of the construction module 200 itself, to enable the construction module 200 to be precisely positioned and connected.

[00156] The top reference plate 110 and the bottom reference plate 120 are described in detail below.

[00157] As shown in Figs. 5 to 7, the top reference plate 110 is configured to be flat, so as to be placed horizontally at the top predetermined position. The top reference plate 110 is provided with a top positioning hole that is depressed downwardly, to facilitate the placing of a laser reflector, so that the top reference plate 110 may be positioned to the top predetermined position of the construction module 200 via the top positioning hole. In the present embodiment, the top reference plate 110 is provided with a positioning cone 111 and a top small positioning hole 113. The positioning cone 111 protrudes upwardly, to be used to extend through the bottom reference plate 120 of another construction-module device. A positioning-cone positioning hole 112 is provided at the top of the positioning cone 111. It can be understood that, here, the other construction-module device is stacked over the construction module 200.

[00158] The positioning-cone positioning hole 112 and the top small positioning hole 113 are top positioning holes. In other words, the top positioning hole includes the positioning-cone positioning hole 112 and the top small positioning hole 113. The positioning-cone positioning hole 112 and the top small positioning hole 113 cooperate to position the top reference plate 110. Optionally, the top small positioning hole 113 may be disposed far away from the positioning cone 111.

[00159] It should be noted that the positions where the positioning-cone positioning hole 112 and the top small positioning hole 113 are located may be understood as the positioning points that are selected for positioning the top reference plate 110. The top reference plate 110 can be precisely positioned by means of the two top positioning holes. Where required and/or desired, the top surface of the positioning cone 111 and the top small positioning hole 113 may be configured to be of other suitable shapes, to facilitate the placing of a laser reflector [00160] Particularly, as shown in Fig. 7, the positioning cone 111 comprises a cone head 114, a cone body 115 and a cone bottom 116. The cone head 114 is a circular cone and can serve to guide in the process of aligning with the bottom reference plate 120 of another construction-module device. The cone body 115 is a cylinder. Accordingly, the positioning cone 111 can bear force uniformly, so that the top reference plate 110 is more firmly connected to the construction module 200. Certainly, the cone head 114 may also be a pyramid. The positioning-cone positioning hole 112 is provided at the top of the cone head 114. The cone bottom 116 is used to be connected to the top reference plate 110 [00161] The transition between the bottom of the cone head 114 and the top of the cone body 115 is a circular arc. The diameter of the bottom of the cone head 114 is not greater than the diameter of the top of the cone body 115. The cone body 115 has a positioning cylindrical surface. The positioning cylindrical surface is provided continuously circumferentially along the center axis of the cone body 115. The center of the positioning-cone positioning hole 112 and the center axis of the cone body 115 coincide. The cone bottom 116 is a cylinder with thread. The thread surrounds continuously circumferentially along the center axis of the cone bottom 116. The center axis of the cone bottom 116 and the center axis of the cone body 115 coincide. All of the center line of the positioning-cone positioning hole 112, the center axis of the cone head 114, the center axis of the cone body 115, and the center axis of the cone bottom 116 coincide, which is the center axis of the positioning cone Ill, The top reference plate 110 is provided with a top large positioning hole 117, and the cone bottom 116 is connected to the top large positioning hole 117 via the thread. Certainly, the cone bottom 116 may not be provided with the thread, but instead be connected to the top reference plate 110 (the top large positioning hole 117) by other suitable approaches such as welding.

[00162] Preferably, the center axis of the positioning cone 111 and the center line of the top large positioning hole 117 coincide. Therefore, the positioning precision of the top reference plate 110 on the construction module 200 can be ensured.

[00163] Further, referring to Figs. 5 and 6, the top reference plate 110 may further be provided with a top connecting hole 118 for a fastener 170 to pass through, to connect the top reference plate 110 to the bottom reference plate of another construction-module device.

[00164] Optionally the cone body 115 may be provided with an operating hole, and the operating hole may be a through hole, which could be connected with an operating element (for example, an operating rod). When the positioning cone 111 is being connected to the thread of the top large positioning hole 1172 the operating personnel may operate the operating element to cause it to rotate about the center axis of the positioning cone 111, whereby the positioning cone 111 in turn rotates along therewith. That enables the operating personnel not to have to directly operate the positioning cone 111.

[00165] Furthermore, the illustrated embodiment exemplarily shows that the top reference plate 110 is a rectangular plate. Certainly, the top reference plate 110 may also be any one of a square plate, a circular plate, and a triangular plate. In the present embodiment, preferably, the configurations of the four top reference plates 110 are the same. Where required and/or desired, the shapes of the four top reference plates 110 are not limited to the same shape, and they may have shapes different from each other. The corner portions of the top reference plate 110 may be chamfered, to avoid the operating personnel from being injured when moving the top reference plate 110.

[00166] Optionally, in the present embodiment, the top corner portion of the construction module 200 is provided with a top corner fitting. The corner portion of the top reference plate 110 may be provided with a top-reference-plate notch 119, to be used to match with the top corner fitting to accommodate the top corner fitting (referring to Fig. 4). The shape of the top-reference-plate notch 119 is adapted for the shape of the top corner fitting of the construction module 200, to facilitate the mounting of the top reference plate 110.

[00167] As shown in Fig. 4, the bottom reference plate 120 is configured to be flat, so as to be placed horizontally at the bottom predetermined position. The bottom reference plate 120 is provided with bottom positioning holes, so that the bottom reference plate 120 may be positioned to the bottom predetermined position via the bottom positioning holes. The bottom positioning holes include a bottom large positioning hole 121 and a bottom small positioning hole 122. The bottom large positioning hole 121 is used to be in clearance fit with the positioning cone of another construction-module device or with a tooling cone 331 provided at a tooling stage 320 (described in detail below). The bottom small positioning hole 122 is used to place a laser reflector. It can be understood that, here, the other construction-module device is stacked under the construction module 200.

[00168] Further, the bottom large positioning hole 121 may correspond to the positioning cone at the top large positioning hole of the top reference plate of the other construction-module device (which, here, mainly refers to the corresponding of the positions). The positioning cone 111 may pass through the bottom large positioning hole 121, so as to connect the bottom reference plate 120 with the top reference plate 110. Furthermore, the bottom large positioning hole 121 may also correspond to the tooling cone 331 of the tooling stage 320. The tooling cone 331 may pass through the bottom large positioning hole 121, so as to position the bottom reference plate 120 by means of the tooling stage 320 before the bottom reference plate 120 is connected to the construction module 200.

[00169] It should be noted that the position where the bottom small positioning hole 122 is located may be understood as the positioning point that is selected for positioning the bottom reference plate 120. The bottom reference plate 120 can be precisely positioned by means of the two bottom positioning holes. Where required and/or desired, the bottom small positioning hole 122 may be configured to be of other suitable shapes, to facilitate the placing of a laser reflector.

[00170] Further, the bottom reference plate 120 may further be provided with a bottom connecting hole 123 for a fastener 170 to pass through, to connect the bottom reference plate 120 to the top reference plate of another construction-module device. Particularly, the bottom connecting hole 123 corresponds to the top connecting hole of the top reference plate of the other construction-module device.

[00171] Preferably, the bottom large positioning hole 121 is a through hole and may be provided adjacent to a bottom-reference-plate notch 124. The bottom small positioning hole 122 is a through hole and may be provided far away from the positioning cone 111. The bottom small positioning hole 122 may be a round hole or a hole of another suitable shape. In the illustrated embodiment, the bottom small positioning hole 122 is a through hole, and certainly it may also be other suitable holes such as a blind hole. The bottom connecting hole 123 may be provided between the bottom large positioning hole 121 and the bottom small positioning hole 122. The pore diameter of the bottom large positioning hole 121 may be greater than the pore diameter of the bottom connecting hole 123. The pore diameter of the bottom connecting hole 123 may be greater than the pore diameter of the bottom small positioning hole 122.

[00172] Furthermore, the illustrated embodiment exemplarily shows that the bottom reference plate 120 is configured to be a rectangular plate. Certainly, the bottom reference plate 120 may also be any one of a square plate, a circular plate, and a triangular plate. In the present embodiment, preferably, the configurations of the four bottom reference plates 120 are the same. Where required and/or desired, the shapes of the four bottom reference plates 120 are not limited to the same shape, and they may have shapes different from each other. The corner portions of the bottom reference plate 120 may be chamfered, to avoid the operating personnel from being injured when moving the bottom reference plate 120.

[00173] Optionally, in the present embodiment, the bottom corner portion of the construction module 200 is provided with a bottom corner fitting. The corner portions of the bottom reference plate 120 may be provided with a bottom-reference-plate notch 124, to be used to match with the bottom corner fitting to accommodate the bottom comer fitting (referring to Fig. 4). The shape of the bottom-reference-plate notch 124 is adapted for the shape of the bottom corner fitting of the construction module 200, to facilitate the mounting of the bottom reference plate 120.

[00174] Particularly, as shown in Figs. 8 to 10 and 13, the bottom reference plates 120 include a first bottom reference plate 130, a second bottom reference plate 140, a third bottom reference plate 150, and a fourth bottom reference plate 160 that are individually connected to the bottom corner portions of the construction module 200 (referring to Fig. 13). The structures/configurations of the first bottom reference plate 130, the second bottom reference plate 140, the third bottom reference plate 150, and the fourth bottom reference plate 160 are approximately the same as the structure/configuration of the bottom reference plate 120, except for the shape of the bottom large positioning hole 121. For sake of brevity, the same parts will not be discussed repeatedly.

[00175] As shown in Fig. 8, the first bottom reference plate 130 comprises a first bottom large positioning hole 131, a first bottom connecting hole 133, and a first bottom small positioning hole 132. The first bottom large positioning hole HI and the first bottom small positioning hole 132 cooperate to position the first bottom reference plate 130.

[00176] The first bottom large positioning hole 131 is a round hole. The first bottom large positioning hole 131 is in clearance fit with the positioning cone of another construction-module device or a tooling cone, with a fit tolerance between +0.5mm and ±1mm.

[00177] As shown in FIG. 9, the second bottom reference plate 140 comprises a second bottom large positioning hole 141, a second bottom connecting hole 143, and a second bottom small positioning hole 142. The second bottom large positioning hole 141 and the second bottom small positioning hole 142 cooperate to position the second bottom reference plate 140.

[00178] The second bottom large positioning hole 141 is a long-circle hole. The width of the long-circle hole is approximately equal to the diameter of the first bottom large positioning hole 131. The length of the long-circle hole is not less than the diameter of a third bottom large positioning hole 151 (described in detail below). The second bottom large positioning hole 141 is in clearance fit with the positioning cone of another construction-module device or a tooling cones 331, and the hole walls of the long-circle hole in the hole-width direction are in clearance fit with the positioning cone 111, with a fit tolerance between +0.5mm and +1mm.

[00179] As shown in Fig. 10, the third bottom reference plate 150 comprises the third bottom large positioning hole 151, a third bottom connecting hole 153, and a third bottom small positioning hole 152. The third bottom large positioning hole 151 and the third bottom small positioning hole 152 cooperate to position the third bottom reference plate 150.

[00180] The third bottom large positioning hole 151 is a round hole. The diameter of the third bottom large positioning hole 151 is greater than the diameter of the first bottom large positioning hole 131. Because the diameter of the third bottom large positioning hole 151 is greater than the diameter of the first bottom large positioning hole 131, the fit tolerance between the third bottom large positioning hole 151 and the positioning cone 111 is not defined.

[00181] Referring to Fig. 13, the fourth bottom reference plate 160 comprises a fourth bottom large positioning hole, a fourth bottom connecting hole 163, and a fourth bottom small positioning hole. The fourth bottom large positioning hole and the fourth bottom small positioning hole cooperate to position the fourth bottom reference plate 160.

[00182] Optionally, the structure of the fourth bottom reference plate 160 and the structure of the third bottom reference plate 150 may be the same. Where required and/or desired, the structure of the fourth bottom reference plate 160 may be configured to be the same as the structure of the first bottom reference plate 130, or to be the same as the structure of the second bottom reference plate 140.

[00183] In the present embodiment, the first bottom reference plate 130 and the second bottom reference plate 140 are arranged in the length direction of the construction module 200, the third bottom reference plate 150 and the first bottom reference plate 130 are arranged in the width direction of the construction module 200, and the fourth bottom reference plate 160 and the first bottom reference plate 130 are arranged in the diagonal line of the construction module 200.

[00184] The top reference plate 110 may be connected to the top of the construction module 200 by welding or by a fastener. The bottom reference plate 120 may be connected to the bottom of the construction module 200 by welding or by a fastener. The top surfaces of the four top reference plates 110 are coplanar to form a top reference plane. The bottom surfaces of the four bottom reference plates 120 are coplanar to form a bottom reference plane. The top reference plane and the bottom reference plane are parallel. Accordingly, it can be ensured that the subsequent stacking process of the construction modules 200 uses the top reference plates 110 and the bottom reference plates 120 as the reference, thereby preventing the positioning errors caused by manufacturing deviations of the construction modules 200 themselves.

[00185] Further, the top comer portions of the construction module 200 may be provided with a frame structure, to facilitate to mount the top reference plates 110 to the frame structure. The positioning and connecting device 100 may further comprise a plurality of top gaskets 101. The top gaskets 101 are provided between the top reference plates 110 and the construction module 200, i.e., between the top reference plates 110 and the frame structure, to fill the gaps between the top reference plates 110 and the top of the construction module 200. The upper and lower surfaces of the top gaskets 101 respectively abut the top reference plates 110 and the construction module 200, thereby enabling the top surfaces of the four top reference plates 110 to maintain coplanar to form the top reference plane. In view that the top surface of the construction module 200 may be uneven, the thicknesses of the top gaskets 101 may be different, so as to reasonably arrange them, thereby enabling the four top reference plates 110 to maintain coplanar. Furthermore, in the process described below of positioning the top reference plates 110, the top gaskets 101 may be used to level the top reference plates 110. Optionally, the top gaskets 101 may be welded to the construction module 200 together with the top reference plates 110.

[00186] Optionally, as shown in Fig. 11, in order to facilitate the operating personnel to operate the top gasket 101, the top gasket 101 has a turnup 103. When the top reference plate 110 is placed over a top gasket 101, the turnup 103 does not interfere with the top reference plate 110. When the top reference plate 110 is placed over the plurality of top gaskets 101, the top gaskets 101 are arranged to surround the edges of the top reference plate 110, and the tumups 103 of the plurality of top gaskets 101 are also arranged to surround the edges of the top reference plate 110, so that the operating personnel can, by operating the tumups 103, insert the top gaskets 101 between the top reference plate 110 and the construction module 200.

[00187] Further, the bottom comer portions of the construction module 200 may be provided with a frame structure, to facilitate to mount the bottom reference plates 120 to the frame structure. Referring to Fig. 4, the positioning and connecting device 100 may further comprise a plurality of bottom gaskets 102. The bottom gaskets 102 are provided between the bottom reference plates 120 and the construction module 200, i.e., between the bottom reference plates 120 and the frame structure, to fill the gaps between the bottom reference plates 120 and the bottom of the construction module 200. The upper and lower surfaces of the bottom gaskets 102 respectively abut the construction module 200 and the bottom reference plates 120, thereby enabling the bottom surfaces of the four bottom reference plates 120 to maintain coplanar to form the bottom reference plane. In view that the bottom surface of the construction module 200 may be uneven, the thicknesses of the bottom gaskets 102 may be different, so as to reasonably arrange them, thereby enabling the four bottom reference plates 120 to maintain coplanar. Optionally, the bottom gaskets 102 may be welded to the construction module 200 together with the bottom reference plates 120. The structure of the bottom gaskets 102 are the same as that of the top gaskets 101, and are not discussed repeatedly here.

[00188[ Construction-module devices that are vertically stacked and/or horizontally abutted are described below.

[00189] As shown in Figs. 2 to 4, the illustrated embodiment exemplarily shows four construction-module devices, which are two upper-layer construction-module devices and two lower-layer construction-module devices. The construction-module devices in each of the layers are arranged side by side, and the construction modules 200 of the construction-module devices that are vertically stacked are connected by the positioning and connecting device 100. Particularly, the construction modules 200 include a first construction module 210 and a second construction module 220 that are arranged side by side, and a third construction module 230 and a fourth construction module 240 that are arranged side by side. The first construction module 210 is stacked over the third construction module 230, and the second construction module 220 is stacked over the fourth construction module 240. In other words, the first construction module 210 and the second construction module 220 are the upper-layer construction modules, and the third construction module 230 and the fourth construction module 240 are the lower-layer construction modules. Although the figures merely show the corner portions of the construction modules, it can be understood that all of the tops and the bottoms of all of the construction modules are individually connected to the top reference plates 110 and the bottom reference plates 120.

[00190] A first-construction-module bottom reference plate 120a and a third-construction-module top reference plate 110a vertically correspond. A second-constructionmodule bottom reference plate 120b and a fourth-construction-module top reference plate 110b vertically correspond. The bottom surface of the first-construction-module bottom reference plate 120a and the bottom surface of the second-construction-module bottom reference plate 120b are coplanar, i.e., in the same bottom reference plane. The top surface of the third-con structi on-module top reference plate 110a and the top surface of the fourth-constructionmodule top reference plate 110b are coplanar, i.e., in the same top reference plane.

[00191] In order to facilitate to connect the construction-module devices that are side by side, further,as shown in Fig. 4, the present embodiment further comprises a horizontal connector 180 The horizontal connector 180 is preferably plate-shaped. The horizontal connector 180 is provided at the corner portions of the construction modules that are arranged side by side, and is provided between the upper-layer construction-module devices and the lower-layer construction-module devices. In other words, the horizontal connector 180 is provided between the bottom reference plates 120 of the upper-layer construction modules (the first and second construction modules 210, 220) and the top reference plates 110 of the lower-layer construction modules (the third and fourth construction modules 230, 240). Particularly, the horizontal connector 180 is parallel to and abuts the first-construction-module bottom reference plate 120a, the second-construction-module bottom reference plate 120b, the thirdconstruction-module top reference plate 110a, arid the fourth-construction-module top reference plate 110b. By means of the horizontal connector 180, the construction-module devices can be connected in the horizontal direction, arid the connection strength of the positioning and connecting device 100 can be increased. The horizontal connector 180 may overlap with each of the reference plates at the corner portions of the construction modules. Particularly, the horizontal connector 180 may vertically overlap with the first-constructionmodule bottom reference plate 120a and the second-construction-module bottom reference plate 120b, and the third-construction-module top reference plate 110a and the fourthconstruction-module top reference plate 110b.

[00192] The horizontal connector 180 is provided with horizontal-connector positioning holes that are symmetrically arranged and horizontal-connector connecting holes that are symmetrically arranged. The horizontal-connector positioning holes are used for the positioning cones of the top reference plates of the lower-layer construction modules to pass through. The horizontal-connector connecting holes are used for the fasteners 170 to pass through.

[00193] In the illustrated embodiment, referring to Fig. 4, the horizontal-connector positioning holes include a first horizontal-connector positioning hole 181 and a second horizontal-connector positioning hole 182. The horizontal-connector connecting holes include a first horizontal-connector connecting hole 183 and a second horizontal-connector connecting hole 184. The first horizontal-connector positioning hole 181 and the first horizontal-connector connecting hole 183 will be taken as the example for the description below. The first horizontal-connector positioning hole 181 corresponds to a positioning cone 111a of the thirdconstruction-module top reference plate 110a and a bottom large positioning hole 121a of the first-construction-module bottom reference plate 120a. The first horizontal-connector connecting hole 183 corresponds to a top connecting hole 118a of the third-construction-module top reference plate 110a and a bottom connecting hole 123a of the first-constructionmodule bottom reference plate 120a The first horizontal-connector positioning hole 181 is in clearance fit with the positioning cylindrical surface of the positioning cone 111a of the thirdconstruction-module top reference plate 110a. As described above, the positioning cone 1 I la of the third-construction-module top reference plate 110a and the bottom large positioning hole 121a of the first-construction-module bottom reference plate 120a are in clearance fit [00194] When the first construction module 210 and the third construction module 230 are being vertically stacked, the positioning cone 11 la of the third-construction-module top reference plate 110a can sequentially pass through the first horizontal-connector positioning hole 181 and the bottom large positioning hole 121a of the first-constructionmodule bottom reference plate 120a. The fasteners 170 can sequentially pass through the bottom connecting hole 123a of the first-construction-module bottom reference plate I 20a, the first horizontal-connector connecting hole 183, and the top connecting hole 118a of the thirdconstruction-module top reference plate 110a from top to bottom, and connect them together.

[00195] More particularly, the center axis of the positioning cone 111a of the third-construction-module top reference plate 110a, the center of the first horizontal-connector positioning hole 181, and the center line of the bottom large positioning hole 121a of the firstconstruction-module bottom reference plate 120a coincide The center of the top connecting hole 118a of the third-construction-module top reference plate 110a, the center of the first horizontal-connector connecting hole, and the center line of the bottom connecting hole 123a of the first-construction-module bottom reference plate 120a coincide.

[00196] Similarly, when the second construction module 220 and the fourth construction module 240 are being vertically stacked, a positioning cone 111b of the fourthconstruction-module top reference plate 110b can sequentially pass through the second horizontal-connector positioning hole 182 and a bottom large positioning hole 121b of the second-construction-module bottom reference plate 120b. The fasteners 170 can sequentially pass through a bottom connecting hole 123b of the second-construction-module bottom reference plate 120b, the second horizontal-connector connecting hole 184, and a top connecting hole 118b of the fourth-construction-module top reference plate 110b from top to bottom, and connect them together. Accordingly, the second construction module 220 and the fourth construction module 240 can be connected together.

[00197] Therefore, by means of the top reference plates 110, the bottom reference plates 120, and the horizontal connector 180, the corner portions of the neighboring construction modules can be connected together, thereby realizing the connection of the four con structi on modules.

[00198] Optionally as shown in Figs. 2 to 4, the fastener 170 comprises a bolt 171, a nut 172, and a stopper 173 that contains and limits the position of the nut 172. Particularly, the stopper 173 is provided under the top connecting hole of a lower-layer-construction-module top reference plate (for example, the third-construction-module top reference plate 110a), and the stopper 173 is fixedly connected to the lower-layer-construction-module top reference plate by welding or by thread connection. As shown in Fig. 12, the stopper 173 has a main body 175 and Z-shaped bent structures 176. The number of the bent structures 176 is three, the three bent structures 176 are provided along the circumference of the main body 175 of the stopper 173 with spacing therebetween, and the angle between any two of the three bent structures 176 is 120°. The nut 172 is provided between the lower-layer-construction-module top reference plate and the stopper 173, so that the lower-layer-construction-module top reference plate and the stopper 173 limit the rotation of the nut 172, to prevent its loosening or falling The main body of the stopper 173 may further be provided with a bolt via-hole 177, to prevent the interference between the stopper 173 and the bolt 171. The nut 172 is preferably a hexagon nut. The fastener further comprises a bolt gasket 174, to reduce the wear to the reference plate during the fastening, and to increase the strength of the bolt connection.

[00199] The corner portions of the construction modules of the present embodiment may be provided with top corner fittings and bottom corner fittings (referring to Fig. 4). The top corner fittings and the bottom corner fittings, in the operations of the construction modules such as lifting, transportation, fixing, and stacking, serve to transmit the forces in various directions, and can also protect the construction modules.

[00200] In order to ensure that the corresponding top reference plates and bottom reference plates of the upper-layer construction-module devices and the lower-layer construction-module devices, in the process of stacking, contact firstly, more preferably the top surfaces of the lower-layer-construction-module top reference plates (for example the third-construction-module bottom reference plate) are above the top surfaces of the lower-layercon structi on-modul e top corner fittings (for example the third-construction-module top corner fitting), and the bottom surfaces of the upper-layer-construction-module bottom reference plates (for example the first-construction-module bottom reference plate) are below the bottom surfaces of the upper-layer-construction-module bottom corner fittings (for example the firstconstruction-module bottom corner fitting).

[00201] Because the corner portions of the construction modules are the main positions for transmitting load, when the top surfaces of the lower-layer-construction-module top reference plates are above the top surfaces of the lower-layer-construction-module top corner fittings, for example, by taking the third construction module 230 as the example, there will be a gap between the third-construction-module top corner fitting and the horizontal connector 180, so the third-construction-module top corner fitting cannot serve to transmit load. Therefore, a top-corner-fitting gasket 105 may be provided at the third-construction-module top corner fitting (referring to Fig. 4). The top surface of the top-corner-fitting gasket 105 is coplanar with the top surface of the third-construction-module top reference plate 110a, so that the top-corner-fitting gasket 105 can abut the horizontal connector 180. Similarly, when the bottom surfaces of the upper-layer-construction-module bottom reference plates are below the bottom surfaces of the upper-layer-construction-module bottom corner fittings, for example, by taking the first construction module 210 as the example, there will be a gap between the first-construction-module bottom corner fitting and the horizontal connector 180, so the first-con structi on-modul e bottom corner fitting cannot serve to transmit load. Therefore, a bottomcorner-fitting gasket 106 may be provided at the first-construction-module bottom corner fitting (referring to Fig. 4). The bottom surface of the bottom-corner-fitting gasket 106 is coplanar with the bottom surface of the first-construction-module bottom reference plate 120a, so that the bottom-corner-fitting gasket 106 can abut the horizontal connector 180.

[00202] Furthermore, in an embodiment not shown, if it is merely required to connect construction modules that are vertically stacked, the horizontal connector may be omitted, and the bottom reference plates of the upper-layer construction module and the top reference plates of the lower-layer construction module may be connected by merely the fasteners. In the present embodiment, the top-corner-fitting gaskets of the lower-layer construction module and the bottom-corner-fitting gaskets of the upper-layer construction module can abut.

[00203] In an embodiment not shown, the construction-module device may be connected to the ground. That is, the construction module may be connected to the ground via the bottom reference plates. In the present embodiment, the positioning and connecting device further comprises a foundation positioning cone. The foundation positioning cone is provided on the ground. The structure of the foundation positioning cone is approximately the same as the structure of the positioning cone described above, wherein the center axes of the cone head, the cone body, and the cone bottom of the foundation positioning cone coincide The foundation positioning cone may be a plurality of foundation positioning cones, and the positions of the plurality of foundation positioning cones may be located by using a laser locating device of the positioning and connecting system. The plurality of foundation positioning cones correspond to the bottom reference plates of the construction module one by one. The foundation positioning cones pass through the bottom large positioning holes of the bottom reference plates and extend upwardly. The positioning cylindrical surface of one of the foundation positioning cones can match with the first bottom large positioning hole, to limit the degree of freedom of the construction module in the horizontal direction. The positioning cylindrical surface of another of the foundation positioning cones can match with the hole walls of the long-circle hole in the hole-width direction, to limit the residual rotational degree of freedom of the construction module in the horizontal direction.

[00204] The present disclosure further provides a positioning and connecting device 100, the structure of which is the same as the structure of the positioning and connecting device of the construction-module device, and, for sake of brevity, it will not be discussed repeatedly here.

[00205] According to another aspect of the present disclosure, there is further provided a positioning system 300, for positioning the positioning and connecting device 100 to a predetermined position that corresponds to the construction module 200, so as to connect the positioning and connecting device 100 (i.e., the top reference plates 110 and the bottom reference plates 120) to the construction module 200.

[00206] As shown in Figs. 13 and 15, the positioning system 300 comprises a laser locating device 310 and the tooling stage 320. The laser locating device 310 and the tooling stage 320 cooperate to accurately locate the positions of the bottom reference plates 120 and the top reference plates 110 of the positioning and connecting device. Particularly, the laser locating device 310 and the tooling stage 320 cooperate to position the bottom reference plates 120 to the bottom predetermined positions (referring to Fig. 13). In the state where the construction module 200 is placed on the tooling stage 320, i.e., in the state where the construction module 200 is placed on the bottom reference plates 120 located at the bottom predetermined positions, the laser locating device 310 is used to position the top reference plate 110s to the top predetermined positions (referring to Fig. IS).

[00207] The laser locating device 310 is a three-dimensional laser locating device.

The laser locating device 310 is installed on an elevated stand 311 on the outer side of the tooling stage 320. The positioning system 300 further comprises laser reflectors (not shown) that cooperate with the laser locating device 310 and a controlling device for receiving the signal of the laser locating device 310. The laser reflectors may be placed at positioning points to be measured. The controlling device, in response to the signal of the laser locating device 310, identifies the positions of the positioning points. It can be understood that the laser locating device 310, the laser reflectors, and the controlling device of the present embodiment form a laser tracking and measuring system.

[00208] A person skilled in the art will easily understand that the laser locating device 310 may be the origin of the positioning coordinate system, and the laser locating device 310 can, by using the laser reflection and software, calculate out the coordinate values in the positioning coordinate system of the positions where the laser reflectors are located. Accordingly, a predetermined reference point may be selected from the positioning coordinate system covered by the laser locating device 310, to facilitate the positioning of the bottom reference plates 120 and the top reference plates 110.

[00209] As shown in Fig. 13, the tooling stage 320 is configured to support the bottom reference plates 120 and be able to move and adjust the positions of the bottom reference plates 120.

Optionally, the supporting bases 330 may be provided on the guide rails 340 via lifting assemblies (not shown), and accordingly the supporting bases 330 can move in the vertical direction by means of the lifting assemblies to adjust the positions in the vertical direction. It should be noted that, here, the "adjust the positions in the vertical direction" does not only include adjusting the vertical positions of the supporting bases 330, but also includes adjusting the angular positions of the supporting bases 330 (for example, with respect to the horizontal direction).

[00210] The supporting bases 330 are configured to be able to support and position the bottom reference plates 120 of the positioning and connecting device. The top surfaces of the supporting bases 330 are a flat plane, and the top surfaces are used to abut the bottom reference plates 120. Each of the supporting bases 330 is provided with a tooling cone 331 that protrudes upwardly The tooling cones 331 are used to pass through the bottom reference plates 120 to limit the positions of the bottom reference plates 120. The structure of the tooling cones 331 is approximately the same as the structure of the positioning cones 111 described above. Particularly, as shown in Fig. 14, each of the tooling cones 331 comprises a cone head, a cone body, and a cone bottom. The cone bottom is fixedly connected to the supporting base 330. The transition between the bottom of the cone head and the cone body is a circular arc.

[00211] The cone head of the tooling cone 331 is provided with a tooling-cone positioning hole 332 depressed downwardly, to facilitate the placing of the laser reflector. The center line of the tooling-cone positioning hole 332 and the center axis of the tooling cone 331 coincide. It should be noted that the positions where the tooling-cone positioning hole 332 is located may be understood as the positioning point that is selected for positioning the supporting base 330. The supporting base 330 can be precisely positioned by means of the tooling-cone positioning hole 332. Where required and/or desired, the top surface of the cone head may be configured to be of other suitable shapes, to facilitate the placing of the laser reflector.

[00212] The cone body of the tooling cone 331 may be configured to be a cylinder, which has a positioning cylindrical surface, and the positioning cylindrical surface is provided continuously circumferentially along the center axis of the cone body The center axes of the cone head, the cone body, and the cone bottom of the tooling cones 331 coincide, which is the center axis of the tooling cone 331. The center axis of the tooling cone 331 of the present embodiment extends in the vertical direction.

[00213] Optionally, in the illustrated embodiment, the supporting base 330 may be provided with a supporting-base notch. The bottom-reference-plate notch 124 and the supporting-base notch approximately align vertically. The tooling cone 331 is provided adjacent to the supporting-base notch. In an embodiment not shown, the supporting base 330 may not be provided with the supporting-base notch.

[00214[ The illustrated embodiment exemplarily shows that the tooling stage 320 is configured to, by using the supporting bases 330 and the bottom reference plates 120, be able to carry a construction module 200. Particularly, the supporting bases 330 include a first supporting base 333, a second supporting base 334, a third supporting base 335, and a fourth supporting base 336. The first supporting base 333 and the third supporting base 335 are provided in the transverse direction Dl of the tooling stage 320. The first supporting base 333 and the fourth supporting base 336 are arranged in the diagonal line. In the illustrated embodiment, the first bottom reference plate 130, the second bottom reference plate 140, the third bottom reference plate 150, and the fourth bottom reference plate 160 may be placed respectively on the first supporting base 333, the second supporting base 334, the third supporting base 335, and the fourth supporting base 336. The respective tooling cones 331 of the first supporting base 333, the second supporting base 334, the third supporting base 335, and the fourth supporting base 336 may pass through respectively the first bottom reference plate 130, the second bottom reference plate 140, the third bottom reference plate 150, and the fourth bottom reference plate 160 to limit the positions of them on the supporting bases 330.

[00215] In an embodiment not shown, the first bottom reference plate 130 may be placed on the first supporting base 333, and the second bottom reference plate 140, the third bottom reference plate 150, and the fourth bottom reference plate 160 may be, according to the demands, placed on the second supporting base 334, the third supporting base 335, and the fourth supporting base 336.

[00216] Further, the guide rails 340 are provided on a supporting frame. The guide rails 340 include a first guide rail 341, a second guide rail 342 perpendicular to the first guide rail 341, and a third guide rail 343 parallel to the second guide rail 342. The second guide rail 342 is provided on the first guide rail 341 and is movable with respect to the first guide rail 341. At least two of the supporting bases 330 are provided on the second guide rail 342. The third guide rail 343 is fixed, and at least two of the supporting bases 330 are provided on the third guide rail 343. In the illustrated embodiment, the first supporting base 333 and the second supporting base 334 are provided on the third guide rail 343. The third supporting base 335 and the fourth supporting base 336 are provided on the second guide rail 342, so as to adjust simultaneously the positions of the two supporting bases 330 in the longitudinal direction D2 of the tooling stage 320. Each of the positions of the supporting bases 330 in the transverse direction D1 of the tooling stage 320 can be adjusted freely.

[00217] Optionally, the movements of the supporting bases 330 with respect to the guide rails 340 are realized by using the controlling device. The controlling device, in response to the laser locating device 310, causes each of the supporting bases 330 to move, for example, moving the third supporting base 335 provided on the third guide rail 343, or, by moving the second guide rail 342, causing the second supporting base 334 and the fourth supporting base 336 provided on the second guide rail 342 to move together along the first guide rail 341. Certainly, the controlling device may also control the second supporting base 334 and the fourth supporting base 336 to move with respect to the second guide rail 342. Certainly, the movements of the supporting bases 330 may also be realized manually [00218] Optionally, the respective tooling cones 331 of the first supporting base 333, the second supporting base 334, the third supporting base 335, and the fourth supporting base 336 have the same shape, and all may be configured to be adapted for the shape of the first bottom large positioning hole 131. When the first bottom reference plate 130 is placed at the first supporting base 333, the fit tolerance between the tooling cone 331 of the first supporting base 333 and the first bottom large positioning hole 131 is between +0.5mm and +1mm. However, the second bottom large positioning hole 141, the third bottom large positioning hole 151, and the fourth bottom large positioning hole have larger sizes than that of the first bottom large positioning hole 131 (referring to the above), so that after the tooling cones 331 pass through the corresponding bottom reference plates, the second bottom reference plate 140, the third bottom reference plate 150, and the fourth bottom reference plate 160 can, according to the demands, move in the horizontal direction around the respective tooling cones 331 to adjust the respective positions in the horizontal direction. Optionally, in an embodiment wherein the second bottom large positioning hole 141 is a long-circle hole, when the second bottom reference plate 140 is placed at the second supporting base 334, the fit tolerance between the tooling cone 331 of the second supporting base 334 and the hole walls of the long-circle hole in the hole-width direction is between +0.5mm and +1mm.

[00219] Further, the tooling stage 320 further comprises positioning pins 351. The positioning pins 351 extend upwardly and are used to extend into the bottom corner fittings of the construction module 200 in the state wherein the construction module 200 is placed at the tooling stage 320. Particularly, the positioning pins 351 can pass through corner-fitting holes of the bottom corner fittings and extend into the bottom corner fittings. Accordingly, they can serve to guide in the process of aligning and abutting the construction module 200 and the bottom reference plates 120, to limit the degree of freedom of the construction module 200 in the horizontal direction. The positioning pins 351 are spaced apart from the corresponding supporting bases 330. Fig. 13 shows that the positioning pins 351 are provided on the outer sides of the first supporting base 333 and are spaced apart from the first supporting base 333. The positioning pin 351 is provided at the supporting-base notch of the first supporting base 333. The positioning pin 351 is fixed to a positioning-pin base 352, and the positioning-pin base 352 is spaced apart from the third guide rail 343 provided with the first supporting base 333. Optionally, in an embodiment wherein the supporting frame is fixed to the ground, the positioning-pin base 352 may be fixed to the ground.

[00220] It should be noted that the directional terms used herein, such as the "outer side" and the "upward", refer to the directions with respect to the tooling stage 320 when it is horizontally placed, wherein the "outer side" refers to the direction that is far away from the tooling stage 320.

[00221] The tooling stage 320 further comprises limiting plate 353. The limiting plates 353 extend horizontally toward the corresponding supporting bases 330, and are used to abut the bottom corner fittings of the construction module 200 in the state wherein the construction module 200 is placed at the tooling stage 320. Particularly, the limiting plates 353 may abut the side surfaces of the bottom corner fittings. Accordingly, they can serve to further guide in the process of aligning the construction module 200 and the bottom reference plates 120, to limit the rotational degree of freedom of the construction module 200 in the horizontal direction. The limiting plates 353 are spaced apart from the corresponding supporting base 330. Fig. 13 shows that the limiting plate 353 is provided on the outer side of the second supporting base 334 and spaced apart from the second supporting base 334. The limiting plate 353 is provided on a limiting-plate base 354, and the limiting-plate base 354 is spaced apart from the second guide rail 342 provided with the second supporting base 334. The limiting-plate base 354 may move together with the second guide rail 342, so as to maintain the relative position of the limiting plate 353 with respect to the second supporting base 334 in the longitudinal direction D2 along the tooling stage 320.

[00222] Optionally, the tooling stage 320 further comprises an additional supporting base 337. The additional supporting base 337 is provided between the first supporting base 333 and the second supporting base 334. The additional supporting base 337 is provided on the second guide rail 342 and is movable with respect to the second guide rail 342. Accordingly, referring to Fig. 15, when the construction module 200 is placed at the tooling stage 320, the additional supporting base 337 can support the construction module 200.

[00223] The present disclosure further provides a connecting method for the construction module. The connecting method can enable the positioning and connecting device (the top reference plate 110 and the bottom reference plate 120) to be connected to the construction module 200, so that neighboring construction modules 200 can be connected by the positioning and connecting device 100.

[00224] The connecting method comprises the following steps: [00225] Step Si: by the cooperation between the laser locating device 310 and the tooling stage 320, positioning the supporting bases 330 of the tooling stage 320 to a position where the bottom reference plates 120 correspond to the bottom predetermined positions [00226] In Step SI, the top surface of each of the supporting bases 330 may be leveled to the same horizontal plane by using the laser locating device 310. It can be understood that the top surface of each of the supporting bases 330 has the same horizontal coordinate with respect to the predetermined reference point. Particularly, this step may comprise judging, according to the signals that are reflected by the laser reflectors on the top surfaces of the supporting bases 330, whether the coordinate values of the heights of at least three points of the top surface of each of the supporting bases 330 are the same, to adjust the position of the top surface of each of the supporting bases 330. Optionally, three to five points of the top surface of each of the supporting bases 330 may be selected to measure whether the top surface is horizontal.

[00227] The present embodiment can level the top surfaces of the supporting bases 330 by adjusting the positions of the supporting bases 330 in the vertical direction, thereby enabling the top surface of each of the supporting bases 330 to be leveled to the same horizontal plane. For example, this step may comprise firstly leveling the top surfaces of the supporting bases 330, even if the top surfaces of the supporting bases 330 have already been horizontal, and then adjusting the heights of the supporting bases 330 by using the lifting assemblies to cause the top surfaces of the supporting bases 330 to be in the same horizontal coordinate.

[00228] Further, in Step Si, the supporting bases 330 that have been leveled may be positioned through the positioning points of the supporting bases 330 by using the laser locating device 310. It can be understood that the "positioning points" are fixing points that are selected on the supporting bases 330, and the positioning points move together with the supporting bases 330. In the present embodiment, the positioning points are selected at the tooling-cone positioning holes 332. Particularly, this step may comprise placing the laser reflectors at the tooling-cone positioning holes 332, judging, according to the signals that are reflected by the laser reflectors at the tooling-cone positioning holes 332, whether the positioning points at the tooling-cone positioning holes 332 are located at preset coordinate values, and moving the supporting bases 330 to adjust the positions of the positioning points with respect to the laser locating device 310. For example, when the positioning points are deviated from the preset coordinate value, the positions of the supporting bases 330 are moved in the horizontal direction, and when the positioning points are located at the preset coordinate value, the movement of the supporting bases 330 is stopped. Accordingly, that can realize the positioning of the supporting bases 330 in the horizontal direction. The four supporting bases 330 may be individually positioned.

[00229] It can be understood that the positions of the supporting bases 330 in the horizontal direction are realized by moving the supporting bases 330 by using the controlling device in response to the laser locating device 310. In the present embodiment, each of the supporting bases 330 may be individually moved to adjust its position on the corresponding guide rail 340, and the second guide rail 342 may be moved to adjust the positions of the second supporting base 334 and the fourth supporting base 336 with respect to the first supporting base 333 [00230] Step S2: placing the bottom reference plates 120 on the supporting bases 330 that have been positioned.

[00231] Particularly, this step comprises aligning the bottom large positioning holes 121 of the bottom reference plates 120 with the tooling cones 331 of the supporting bases 330, and, by means of the guide by the cone heads, nesting the bottom reference plates 120 to the tooling cones 331, thereby placing them at the top surfaces of the tooling cones 331. Because the thicknesses of the bottom reference plates 120 are the same, the top surface of each of the bottom reference plates 120 have the same horizontal coordinate with respect to the predetermined reference point [00232] Step 53: by using the laser locating device 310, positioning the bottom reference plates 120 to positions that correspond to the bottom predetermined positions.

[00233] In Step S3, the bottom reference plates 120 may be positioned through the positioning points of the bottom reference plates 120 by using the laser locating device 310. Referring to the above, the positioning points move together with the bottom reference plates 120. In the present embodiment, the positioning points may be selected at the bottom small positioning holes 122. Particularly, this step may comprise placing the laser reflectors at the bottom small positioning holes 122, judging, according to the signals that are reflected by the laser reflectors at the bottom small positioning holes 122, whether the positioning points at the bottom small positioning holes 122 are located at preset coordinate values, and moving the bottom reference plates 120 horizontally around the tooling cones 331 to adjust the positions of the positioning points with respect to the laser locating device 310. Accordingly, that can realize the positioning of the bottom reference plates 120 in the horizontal direction. The four bottom reference plates 120 may be individually positioned.

[00234] Step S4: placing the construction module 200 on the bottom reference plates that have been positioned and connecting the bottom reference plates 120 and the construction module 200.

[00235] In Step 54, the construction module 200 is guided by the positioning pins 351 and/or the limiting plate 353 of the tooling stage 320 and thus placed. Particularly, the construction module 200 may be placed to the bottom reference plates 120 from over the tooling stage 320 by means of hoisting. In the process of aligning the bottom predetermined positions of the construction module 200 with the bottom reference plates 120, the construction module 200 is moved to the top surfaces of the bottom reference plates 120 by means of the guiding by the positioning pins 351 and the limiting plate 353 of the tooling stage 320.

[00236] In view that the bottom surface of the construction module 200 may be uneven, a gap might exist between the construction module 200 and the bottom reference plates 120. Therefore, in Step S4, the bottom gaskets 102 may be provided between the construction module 200 and the bottom reference plates 120, so that the bottom surfaces of the plurality of bottom reference plates 120 that have been connected to the construction module 200 are coplanar. The bottom gaskets 102 of different thicknesses may be selected, and the positions of the bottom gaskets 102 may be set according to the demands, to enable each of the bottom gaskets 102 to abut the construction module 200 and the bottom reference plates 120.

[00237] After the gaskets has been properly provided, the bottom reference plates 120 are connected to the construction module 200. Preferably, the bottom reference plates 120 are welded to the construction module 200.

[00238] Step SS: placing the top reference plates 110 at the top of the construction module 200, and, by using the laser locating device 310, positioning and connecting the top reference plates 110 to the top predetermined positions.

[00239] In Step SS, the top surface of each of the top reference plates 110 may be leveled to the same horizontal plane by using the laser locating device 310. It can be understood that the top surface of each of the top reference plates 110 has the same horizontal coordinate with respect to the predetermined reference point. Particularly, this step may comprise judging, according to the signals that are reflected by the laser reflectors on the top surfaces of the top reference plates 110, whether the coordinate values of the heights of at least three points of the top surface of each of the top reference plates 110 are the same, and adjusting the positions of the top surface of each of the top reference plates 110. Optionally, three to five points of the top surface of each of the top reference plates 110 may be selected to measure whether the top surface is horizontal.

[00240] The present embodiment can level the top surfaces of the top reference plates by providing the top gaskets 101 between the top reference plates 110 and the construction module 200, thereby enabling the top surfaces of the top reference plates 110 to be leveled to the same horizontal plane. In view that the top surface of the construction module 200 may be uneven, it is required to support the top reference plates 110 by means of the top gaskets 101, to enable their top surfaces to be horizontal. The top gaskets 101 of different thicknesses may be selected, and the positions of the top gaskets 101 may be set according to the demands.

[00241] In Step S5, the top reference plates 110 that have been leveled may be positioned through at least two positioning points of the top reference plates 110 by using the laser locating device 310. In the present embodiment, the positioning points may be selected at the positioning-cone positioning holes 112 and the top small positioning holes 113. Particularly, by taking the top small positioning holes 113 as the example, this step may comprise placing the laser reflectors at the top small positioning holes 113, judging, according to the signals that are reflected by the laser reflectors at the top small positioning holes 113, whether the positioning points at the top small positioning holes 113 are located at preset coordinate values, and moving the top reference plates 110 horizontally around the tooling cones 331 to adjust the positions of the positioning points with respect to the laser locating device 310. Accordingly, that can realize the positioning of the top reference plates 110 in the horizontal direction. The four top reference plates 110 may be individually positioned.

[00242] After the top reference plates 110 have been properly positioned, the top reference plates 1100 are connected to the construction module 200. Preferably, the top reference plates 110 are welded to the construction module 200.

[00243] Further, the connecting method further comprises Step So subsequent to Step S5: vertically stacking two construction modules 200 that have been connected to the top reference plates 110 and the bottom reference plates 120, and connecting the bottom reference plates 120 of the upper-layer construction module and the top reference plates 110 of the lower-layer construction module.

[00244] Particularly, this step may comprise firstly moving the upper-layer construction module (referring to the first construction module 210 in Fig. 4) to over the lower-layer construction module (referring to the third construction module 230 in Fig. 4). The process of aligning the bottom reference plates UO of the upper-layer construction module and the top reference plates 110 of the lower-layer construction module may comprise, by means of the guiding by the cone heads 114 of the positioning cones 111, nesting the bottom large positioning holes 121 of the bottom reference plates 120 of the upper-layer construction module to the positioning cones 111 of the top reference plates 110 of the lower-layer construction module, to position the position of the upper-layer construction module, and then, by means of the fasteners 170 such as bolts, connecting the top connecting holes 118 of the top reference plates HO and the bottom connecting holes 123 of the corresponding bottom reference plates 120.

[00245] Further, the connecting method further comprises Step S7 subsequent to Step S5: horizontally providing two construction modules 200 that have been connected to the top reference plates 110 and the bottom reference plates 120, and connecting the top reference plates 110 of the neighboring construction modules by using the horizontal connector 180.

[00246] Particularly, this step may comprise firstly providing side by side and aligning two construction modules 200 (referring to the third construction module 230 and the fourth construction module 240 in Fig. 4), and then nesting the horizontal-connector positioning holes of the horizontal connector 180 individually to the positioning cones 111 of the respective top reference plates 110 of the two construction modules 200, to position the position of the horizontal connector 180.

[00247] In an embodiment wherein a plurality of construction modules 200 are vertically stacked and horizontally provided, for example, in a case of two lower-layer construction modules and two upper-layer construction modules, step S7 may be performed firstly, and Step 56 is then performed. Accordingly, only after the horizontal connector 180 has been placed to the top reference plates 110 of the lower-layer construction modules, can the upper-layer construction modules be placed over the lower-layer construction modules. Furthermore, the positioning cones 111 of the top reference plates 110 of the lower-layer construction modules may pass through the horizontal-connector positioning holes of the horizontal connector 180 and the bottom reference plates 120 of the upper-layer construction modules. Finally, by means of the fasteners 170 such as bolts, the top connecting holes 118 of the top reference plates 110, the horizontal-connector positioning holes of the horizontal connector 180, and the bottom connecting holes 123 of the bottom reference plates 120 are correspondingly connected, to form the stacked construction-module device.
