Description
Technical Field
The present application relates generally to the field of building technology, and more particularly to a connection positioning system for a box-type building module and a modular building having the same.
Background
The modular building is characterized in that the box-type building module is manufactured in advance in a factory, and the box-type building module is assembled and spliced after being transported to a project site, so that a building structure is formed. In connection with the assembly and splicing of box building modules, bolting is often used to enable quick stacking of the box building modules in the field. The positioning of the box-type building module is consistent with the clearance of the standard bolt hole, and the box-type building module can be connected by bolts. Therefore, the positioning of the box-type building modules is particularly important in the project site, otherwise, the box-type building modules cannot be assembled, and the structural performance of the main building body is affected. The box building modules are typically provided with anchor points on the top and bottom surfaces, respectively. According to the arrangement of the building, more than four positioning points are arranged on the same surface. The positioning structure of the positioning point comprises a positioning piece and a positioning hole matched with the positioning piece. The precision requirements of the four positioning points are very high, and important performances such as structural stress, building interior space and the like can be influenced. Referring to fig. 1, in the related art, one of the positioning points is a double-direction tight positioning piece (a positioning piece with tight fit in both the length direction and the width direction), and the other positioning points are loose positioning pieces (a positioning piece with loose fit in both the length direction and the width direction). However, because the box can be twisted in the hoisting process, other positioning points are difficult to obtain very good positioning under the condition that only one bidirectional fastening positioning piece is used. In order to avoid the situation, the loose locating pieces of other locating points are matched with the locating holes to be tightly clamped, so that each locating piece is accurately located, the loose locating pieces are intangibly changed into the tight locating pieces to be used, the four locating pieces are required to be too high in locating precision, and the tight locating pieces lose original meaning. In general, when the loose positioning piece is loosely matched with the positioning hole, the positioning of the box-type building module is poorer, and the problem that the box-type building module is interfered with the box-type building module easily occurs in the hoisting process; if the loose locating piece is in tight fit with the locating hole, the loose locating piece is in a tight locating piece state, and the difficulty of locating the locating piece on site is increased. Moreover, if the positioning of the positioning piece is easy to deviate, the positioning piece cannot enter the positioning hole during hoisting, and the positioning piece is required to be cut or the positioning hole is required to be enlarged, so that the hoisting efficiency is greatly influenced.
Accordingly, there is a need to provide a connection location system for a box-type building module and a modular building having the same to at least partially solve the above-mentioned problems.

Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present application. It will be apparent, however, to one skilled in the art that embodiments of the application may be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order to avoid obscuring the embodiments of the application.
In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present application. It will be apparent that embodiments of the application may be practiced without limitation to the specific details that are set forth by those skilled in the art.
Some technical terms and definitions related to the present application. And (3) tightly positioning pieces: the single side gap for mating with the locating hole in the box building module is typically 1mm to 2mm (including 2 mm). The locating piece is divided into two matching directions along the width direction of the box-type building module and the length direction of the box-type building module on a plane perpendicular to the depth direction of the locating hole, so the tight locating piece is divided into a tight locating piece which is tightly matched with the locating hole along the width direction of the box-type building module or is tightly matched with the locating hole along the length direction of the box-type building module, or a locating piece which is tightly matched with the locating hole along the width direction of the box-type building module and the length direction of the box-type building module. Wherein the positioning hole may be a tapered hole.
Loose positioning piece: the locating holes on the box-type building modules are in loose fit, and the unilateral clearance for the fit is usually more than 2mm (excluding 2 mm); the locating piece is divided into two matching directions along the width direction of the box-type building module and the length direction of the box-type building module on a plane perpendicular to the depth direction of the locating hole, and the loose locating piece is in loose fit with the locating hole along the width direction of the box-type building module and the length direction of the box-type building module. Wherein the positioning hole may be a tapered hole.
Referring to fig. 1, the positioning method provided by the related art generally uses a two-way tight positioning member 10 (a positioning member tightly matching with each other along the length direction of the box-type building module 1 and the width direction of the box-type building module 1) for positioning, and uses a loose positioning member (a positioning member loosely matching with each other along the length direction of the box-type building module 1 and the width direction of the box-type building module 1) for positioning. However, since the box-type building module 1 can be twisted during the hoisting process (see fig. 1, the twisted box-type building module 1') often uses a positioning piece tightly matched in two directions, and other positioning points are difficult to obtain good positioning. Taking a case with a length of 12m and a width of 3m as an example, the gap between the tight positioning member 10 and the positioning hole is 2mm (2 mm gaps along the x-direction and the z-direction respectively), when the box-type building module 1 falls down, if torsion occurs, the outermost point along the length direction of the box-type building module 1 (the point farthest from the tight positioning member 10) can achieve a positioning error of about 300mm (see fig. 1, the position change of the box-type building modules 1 and 1'). In order to avoid this situation, the tight positioning piece 10 needs to be matched with the loose positioning piece, for example, a mode of combining one tight positioning piece 10 with three loose positioning pieces is adopted, and meanwhile, for accurate positioning, the matching of the loose positioning piece and the positioning hole is often tightened, so that the situation that each positioning piece needs to be accurately positioned is formed. Therefore, the loose positioning piece is changed into the tight positioning piece 10 for use in an intangible way, namely, the positioning accuracy requirements on four positioning pieces are too high, and the tight positioning piece 10 also loses the original meaning. In general, when the loose positioning piece is in loose fit with the positioning hole, the positioning of the box-type building module 1 is poorer, and the problem of installation interference between the box-type building module and the box-type building module easily occurs in the hoisting process; if the loose locating piece is in tight fit with the locating hole, the state of the tight locating piece 10 is formed, the difficulty of locating the locating piece on site is increased, deviation is easy to occur in locating of the locating piece, and then the locating piece cannot enter the locating hole during hoisting. In this case, in order to allow the positioning member to enter the positioning hole, the positioning member needs to be cut or the positioning hole needs to be enlarged, which greatly affects the hoisting efficiency.
The application provides a connection positioning system of a box-type building module. As shown in fig. 2 to 15d, the longitudinal direction of the box-type building module 100 is denoted as x-direction, the width direction is denoted as z-direction, and the height direction is denoted as y-direction.
The connection positioning system of the box-type building module of the present application includes a positioning hole 111, a positioning member 200, and a connection plate 230. Wherein the positioning holes 111 are provided to the surface to be positioned of the box-type building module 100. The hole depth direction of the positioning hole 111 is parallel to the y direction. The positioning holes 111 of the same box-type building module 100 are spaced apart in the x-direction. And, the positioning holes 111 located in the same box-type building module 100 are oppositely arranged at intervals in the z-direction. The surface to be positioned of the box-type building module 100 may be constructed as either one of the top surface and the bottom surface of the box-type building module 100, that is, both the top surface and the bottom surface of the box-type building module 100 may be used as the surface to be positioned. The positioning piece 200 is in plug-in fit with the positioning hole 111. The positioning member 200 required for the same surface to be positioned at the completion of positioning includes a tight positioning member 210 and a loose positioning member 220. At least two tight positioning elements 210 are provided for the same surface to be positioned when positioning is completed. At least one of the at least two tight fixtures 210 is configured to be tightly fitted with a corresponding fixture hole 111 in the x-direction. At least one of the at least two tight fixtures 210 is configured to tightly fit with a corresponding fixture hole 111 along the z-direction. That is, at least two of the tight fixtures 210 required for the same surface to be positioned have different tight fitting directions. The loose-fitting parts 220 are configured to be loose-fitted with the corresponding positioning holes 111 in the x-direction and the z-direction, respectively. The connection plate 230 is connected to the positioning member 200. Adjacent positioning pieces 200 for being respectively inserted into the positioning holes 111 of the adjacent box-type building modules 100 are provided on the same connection plate 230, that is, adjacent positioning pieces 200 between the adjacent box-type building modules 100 are provided on the same connection plate 230. The plate thickness direction of the connection plate 230 coincides with the y direction.
According to the connecting and positioning system of the box-type building module, at least two tight positioning pieces 210 are used in the positioning of the same box-type building module 100, the rest is positioned by adopting the loose positioning pieces 220, and the tight matching directions of at least two tight positioning pieces 210 in the at least two tight positioning pieces 210 are different, so that the single box-type building module 100 can be accurately positioned; for the splice positioning of two adjacent box modules, the connecting plates 230 of two adjacent positioning members 200 are constructed as an integral structure, so that the relative positions of two adjacent box building modules 100 are accurately positioned. By adopting the technical scheme, each box-type building module 100 can be accurately positioned in the stacking and splicing of the box-type building modules 100, so that the important performances of structural stress, building space and the like of the building are ensured.
Referring to fig. 2, 3, and 11, in one embodiment of the present application, the connection plate 230 includes two surfaces opposite in the plate thickness direction. One of the two surfaces of the connection plate 230 is provided with the positioning member 200, and the other of the two surfaces of the connection plate 230 is used for connection to the embedment 400. The combination of the connecting plate 230 and the positioning member 200 of this embodiment is suitable for positioning the bottommost box-type building module 100, and the bottommost box-type building module 100 needs to be connected with the embedded member 400 on the building foundation. Therefore, when the connecting plate 230 with the positioning pieces 200 is used, the connecting plate 230 is arranged on the foundation according to the distribution condition of the positioning holes 111 on the bottom surface of the box-type building module 100, the positions of the positioning pieces 200 are matched with the preset positioning requirements (the distribution of the positions of the positioning holes 111 when the box-type building module 100 is positioned), and the positioning pieces 200 are protruded out of the upper surface of the connecting plate 230; then fixing the lower surface of each connection plate 230 to the embedment 400 or the foundation; after the connection plates 230 are fixed, the box-type building module 100 is hoisted to the position where the connection plates 230 are fixed, and the positioning pieces 200 on the connection plates 230 are accurately inserted into the corresponding positioning holes 111 on the bottom surface of the box-type building module 100, so that the positioning of the single box-type building module 100 on the lowest layer is completed. Similarly, in order to position the relative positions of the two adjacent box-type building modules 100 at the bottommost layer when they are spliced, the adjacent positioning members 200 of the two adjacent box-type building modules 100 to be spliced may be mounted on the same connection plate 230, thereby defining the relative positions of the two adjacent box-type building modules 100.
As shown in fig. 4 to 15d, in another embodiment of the present application, two sets of positioning members 200 are provided on the same connection plate 230, the two sets of positioning members 200 are respectively located on two surfaces of the connection plate 230, and the two sets of positioning members 200 on the same connection plate 230 are correspondingly arranged along the thickness direction of the connection plate 230. Taking the posture that the surface of the connection plate 230 is parallel to the horizontal direction as an example, the upper and lower surfaces of the connection plate 230 are respectively provided with a set of positioning members 200, and the set of positioning members 200 on the upper surface may be used to connect the upper layer of the box-type building module 100, and the set of positioning members 200 on the lower surface may be used to connect the lower layer of the box-type building module 100. The positioning member 200 in this case can be used to position two adjacent box building modules 100 in the height direction in the horizontal direction (x-direction and z-direction).
As shown in fig. 2 to 15d, the positioning member 200 may be selectively detachably connected to the connection plate 230 for convenience of disassembly and transportation. Removable means such as a snap fit.
As shown in fig. 2 to 15d, alternatively, the positioning member 200 may be provided directly as an integral member with the connection plate 230 at the prefabrication stage, or may be manufactured as a single member by welding or the like, for the sake of structural stability and accurate positioning.
In addition, as shown in fig. 4 to 6 and 12 to 14, in the process of forming a modular building structure using the box-type building module 100 of the present application, the box-type building modules 100 may be arranged in the same orientation or may be arranged in different orientations (e.g., vertically). In order to meet the positioning requirement when two adjacent box-type building modules 100 which are vertically connected are spliced, the distance between two positioning holes 111 at the extreme ends of the same long edge x direction of the box-type building modules 100 is consistent with the distance between two positioning holes 111 at the same wide edge of the box-type building modules 100. That is, the spacing between the adjacent two positioning holes 111 at the outermost end in the x-direction on the same side of the box-type building module 100 can be adjusted at the stage of prefabrication so that the spacing coincides with the spacing between the two positioning holes 111 with respect to the width direction. Therefore, when the long side to be spliced on one box-type building module 100 is spliced with the wide side to be spliced on the other box-type building module 100, the adjacent positioning pieces 200 are ensured to share one connecting plate 230, the size of the connecting plate 230 can be effectively reduced, and the material cost is further reduced.
Referring to fig. 2 and 3, in the stacking process of the box building modules 100, it is necessary to consider whether the verticality meets the building requirements. In this regard, the connection location system of the box building module of the present application also includes a height compensator. The height compensator may be provided at one or both of above and below the connection plate 230 so that the height of the portion of the box-type building module 100 corresponding to the height compensator is raised. Through setting up the altitude compensation piece, can be used for installing some setpoint at box building module 100 to adjust the height of corresponding position, and then reach and leveling (adjust the straightness that hangs down of box building module 100) box building module 100, finally make the deviation of the straightness that hangs down of box building module 100 in the allowed range. Here, in adjusting the verticality of the box-type building module 100, an instrument for measuring a deviation in a horizontal direction may be selected, or an instrument for measuring a deviation in a plumb direction may be selected.
Referring to fig. 2 and 3, for example, the height compensator may be configured as a height compensating plate 300, and the plate thickness direction of the height compensating plate 300 provided to the connection plate 230 is parallel to the y direction, that is, the thickness of the height compensating plate 300 coincides with the thickness direction of the connection plate 230.
Referring to fig. 2 and 3, in the case where the height compensator is configured as the height compensation plate 300, the height compensation plate 300 may be installed in a lower direction of the connection plate 230 when being used, or may be optionally installed above the connection plate 230. Wherein:
referring to fig. 2, when the connection plate 230 is positioned between the foundation and the lowermost box building module 100, it is preferable that the height compensation plate 300 is disposed at the lower surface of the connection plate 230. Because of the connection plates 230 between the foundation and the lowermost box building module 100, the positioning members 200 are generally installed only at the upper side. Therefore, compared to the upper surface of the connection plate 230, the lower surface of the connection plate 230 has a more sufficient surface area for contacting the height compensation plate 300, and the contact area of the height compensation plate 300 and the connection plate 230 is more stable, so that the positioning is more precise and reliable. Of course, in other embodiments, the height compensation plates 300 may be provided at the lower and upper surfaces of the connection plates 230 of the lowermost layer, respectively, to increase the amount of compensation in the height direction, and the height compensation plates 300 separately disposed at the upper and lower sides of the connection plates 230 may be more stable during use than when two height compensation plates 300 are stacked on the same side of the connection plates 230. In addition, by adding a structure for connecting another height compensation plate 300 to the height compensation plate 300 for the purpose of restricting displacement of two height compensation plates 300 relative to each other in the horizontal direction, it is also possible to allow two or more height compensation plates 300 to be stacked together.
Referring to fig. 2 and 3, when the connection plate 230 is positioned between two adjacent box-type building modules 100 in the height direction, it is preferable that the height compensation plate 300 be disposed at the upper surface of the connection plate 230 or at the lower surface of the connection plate 230. Since the contact portion of the height compensation plate 300 with the box-type building module 100 of the corresponding side is at the corner piece 110 between the adjacent two box-type building modules 100 in the height direction, whether on the upper side or the lower side of the connection plate 230, the contact area is relatively limited. In order to facilitate adjustment of the position of the height compensation plate 300 on the connection plate 230, it may be preferable to install the height compensation plate 300 on the upper side of the connection plate 230.
Further, referring to fig. 3, in case that the height compensation plate 300 is mounted on the surface of the connection plate 230 having the positioning member 200, the height compensation plate 300 of the present application may have a via hole adapted to the positioning member 200, such that the height compensation plate 300 is sleeved outside the positioning member 200. This allows for accurate positioning of the height compensation plate 300 in position on the connection plate 230; moreover, since the height compensation plate 300 is limited by the positioning member 200, the positioning member 200 can limit the displacement of the height compensation plate 300 in the horizontal direction in the use state, so that the effective contact area between the height compensation plate 300 and the box-type building module 100 is kept unchanged in the use process, and the stability of the height compensation plate 300 in the use process can be ensured.
The connection plate 230 of the present application may be made of steel or rubber.
In addition, referring to fig. 2 to 14, the positioning hole 111 of the present application may be configured as a corner piece hole on the corner piece 110 of the box-type building module 100, an additional hole formed at another position (such as a side beam) of the box-type building module 100, or both types of positioning holes 111 (the aforementioned corner piece hole and the additional hole). In general, corner fitting holes for positioning are formed in the corner fitting 110 of the box-type building module 100 in the y-direction, and the corner fitting 110 is distributed at least at four corner portions of the box-type building module 100, so that positioning can be achieved with a small positioning error when the corner fitting holes are used as the positioning holes 111. Of course, in some embodiments, the number of locating holes 111 required will vary depending on the length of the box building module 100. When the length of the box-type building module 100 is long (for example, the length of the box-type building module 100 is greater than or equal to 12 m), at least three positioning holes 111 (as shown in fig. 6, 8, 9, and 13 and 14) may be provided at the same side member in order to reduce positioning errors of different portions of the box-type building module 100 in the x-direction. The positioning hole 111 in the middle may be a middle corner piece provided on the side beam of the box-type building module 100 (when there is a middle corner piece in the middle of the side beam of the box-type building module 100), or may be a hole additionally formed in the middle of the side beam of the box-type building module 100.
Referring to fig. 2 to 15d, the size of the box-type building module 100 in the x-direction to which the present application is applied is less than or equal to 18m, and the size of the box-type building module 100 in the z-direction is less than or equal to 5m. When the dimension of the box building module 100 in the x-direction is greater than or equal to 12m, more than three tightening fixtures are used. This is due to the fact that the dimensions of the box-like building module 100 in the x-direction are relatively large, and thus the tolerance is relatively large, the fastening and positioning members 210 may be added in the middle of the box-like building module 100, and the added fastening and positioning members 210 preferably are in close fit with the box-like building module 100 in the x-direction, or in close fit with the box-like building module 100 in the z-direction, or in both.
Further, referring to fig. 1 to 15d, at least one of the at least two tight fixtures 210 may be configured to be tightly fitted with the corresponding fixture hole 111 in both the x-direction and the z-direction, and the number of tight fixtures 210 being tightly fitted in both the x-direction and the z-direction is smaller than the total number of tight fixtures 210. In other words, some of the at least two tight fixtures 210 may be tight fixtures 210 that are tight-fitting in both the x-direction and the z-direction, which may help to improve positioning accuracy. However, the number of the tight fixtures 210 in the x-direction and the z-direction cannot exceed the number of the tight fixtures 210, otherwise the positioning difficulty of the tight fixtures 210 themselves in positioning and mounting on the foundation and the surface to be positioned is increased. Preferably, one of the tight fixtures 210 is allowed to have a tight fixture 210 along the x-direction and the z-direction.
Referring to fig. 2 to 15d, the connection and positioning system of the box building module of the present application is applied using two or three tight-fitting tight-positioning members 210 in different directions. Preferably, two tight fixtures 210 are used, so that the positioning system is simple in structure and convenient to operate. The two tight fixtures 210 are in a mating relationship with the box building module 100: one of the two fastening members 210 is used to control the longitudinal direction (x-direction) of the box-type building module 100, i.e., to perform a fastening fit along the longitudinal direction (x-direction) of the box-type building module 100 and to perform a loose fit along the width direction (z-direction) of the box-type building module 100; the other one of the two fastening members 210 is used to control the width direction (z direction) of the box-type building module 100, i.e., to make a tight fit along the width direction (z direction) of the box-type building module 100 and to make a loose fit along the length direction (x direction) of the box-type building module 100. The arrangement of the two tight fixtures 210, which are tightly fitted in a single direction (in the x-direction or the z-direction), may be arranged in any direction of the box building module 100, for example, in a straight direction, or in a diagonal direction, depending on the characteristics of the project. By adopting the two tight positioning pieces 210 which are tightly matched along a single direction and have different tight matching directions, the box-type building module 100 can effectively limit the rotation angle of the box-type building module 100 when falling into the box, thereby well controlling the positioning precision when falling into the box. The positioned box building module 100 can only translate along the x direction or the z direction relative to the corresponding tight positioner 210, and can better meet the required positioning precision. Taking a case with a length of 12m and a width of 3m as an example, the clearance between the fastening member 210 and the positioning hole 111 in the fastening direction is 2mm (2 mm clearance in each of x and z directions), and the box-type building module 100 can only translate 2mm in the length and width directions at most when the box-type building module 100 falls down. The present application is applicable to various modularized building box-type building modules 100, but the width of the box-type building module 100 is not more than 5m, and the length is not more than 18m.
Referring to fig. 2 to 15d, the present application also provides a modular building comprising a box-type building module 100 and the above-mentioned connection positioning system of the box-type building module. One or both of the top and bottom surfaces of the box building module 100 has a positioning hole 111, and the hole depth direction of the positioning hole 111 is parallel to the y direction. The positioning holes 111 located on the same face (top or bottom face) of the box-type building module 100 are spaced apart in the x-direction. And, the positioning holes 111 located at the same side of the box-type building module 100 are oppositely arranged at intervals along the z-direction. The x direction is the length direction of the box-type building module 100, the z direction is the width direction of the box-type building module 100, and the y direction is the height direction of the box-type building module 100.
According to the modular building provided by the application, by applying the connecting and positioning system of the box-type building module, the accurate positioning of the same container can be realized by adopting at least two tight positioning pieces 210 with different tight matching directions, and the accurate positioning of the relative positions of the two adjacent containers on the same layer can be realized by constructing the adjacent connecting plates 230 of the two spliced containers into a whole. Therefore, the important performances of structural stress, building space and the like of the modularized building are reliably ensured.
Referring to fig. 2 to 15d, one embodiment of the modular building of the present application at the time of construction is:
1. dividing the positioning direction into three directions: the y-direction is used for elevation (along the height of the building to be constructed), and the x-direction and z-direction are horizontal directions. The y direction may be understood as the height direction of the box-type building module 100, and the x direction may be understood as the length direction of the box-type building module 100 or the width direction of the box-type building module 100.
2. In terms of elevation, a laser is made (e.g., using a laser level meter) or a wire is paid out (e.g., using a plumb bob), and a pad is used at the lower or upper portion of the connection plate 230 to adjust the elevation, thereby ensuring the accuracy of the elevation direction. The backing plate may be placed, welded or otherwise mounted.
3. When the first-floor box building module 100 is positioned, two tight positioning pieces 210 which are tightly matched along different directions are arranged, and the rest is loose positioning pieces 220. Wherein, two tight fits in different directions means that one of the two tight positioning pieces 210 forms a tight fit with the positioning hole 111 on the box-type building module 100 in the x direction, and the other of the two tight positioning pieces 210 forms a tight fit with the positioning hole 111 on the box-type building module 100 in the z direction. Two tight fixtures 210 are typically disposed at both ends in the length direction (x-direction) of the box building module 100 to minimize positioning errors.
When two box-type building modules 100 on the same floor are spliced, two adjacent box-type building modules 100 are restricted by using the same connecting plate 230. Thereby, a relative position between two adjacent spliced box building modules 100 is achieved.
4. The positioning method of the second floor and the second or more floors of the box-type building modules 100 can be referred to as the positioning method of the first floor of the box-type building modules 100. In the positioning operation, it is necessary to level the top surface of the lower box-type building module 100 and then perform the positioning of the tight positioning member 210 and the loose positioning member 220.
Referring to fig. 2 to 15d, the embodiments of the present application at the time of construction are not limited to the above-listed embodiments. For example, when the length of the box-type building module 100 is long, the number of the fastening members 210 may be appropriately increased to further reduce the positioning error of each portion of the box-type building module 100 in the x-direction, thereby ensuring the positioning accuracy.
Referring to fig. 2 to 15d, the positioning member 200 of the present application has a cone that can be inserted into the positioning hole 111, and the outer contour of the cone is tapered to serve as a guiding portion of the positioning member 200, so that the positioning member 200 can be easily inserted into the positioning hole 111. The shape of the positioning member 200 may be one of the shapes shown in fig. 15a to 15d, or may be any one of octagon, circle, oval, etc. The internal configuration of the positioning member 200 may be hollow (as shown in fig. 15 d) or solid (as shown in fig. 15 c). The size of the positioning member 200 can be adapted during the prefabrication stage according to the size of the corner fitting 110.
The positioning hole 111 of the present application may be a tapered hole. The tapered holes are arranged in a convergent manner along the insertion direction of the positioning member 200, that is, the radial dimension of the tapered holes decreases along the insertion direction of the positioning member 200.
Referring to fig. 2 to 15d, the connection positioning system of the box-type building module and the modular building having the same according to the present application enable the box-type building module 100 to be accurately dropped by using two tight positioning pieces 210 tightly fitted with corresponding positioning holes 111 in different directions, and can meet the bolt assembly requirements after dropping, and also can meet the mechanical properties, anti-seismic properties, etc. of the building structure, and can also ensure the clearance requirements, verticality requirements, etc. of the building structure (e.g., stairs, elevator shaft, service shaft, etc.). In the positioning mode of one tight and three loose in the related technology, when the accurate positioning purpose is achieved, the positioning requirements on four cones are too high. In comparison, by adopting the two ways of arranging the tight positioning pieces 210 along different directions, only the two tight positioning pieces 210 can be positioned, one tight positioning piece 210 of the two tight positioning pieces 210 only needs to be positioned accurately in the length direction (x direction), and the other tight positioning piece 210 of the two tight positioning pieces 210 only needs to be positioned accurately in the width direction (z direction); at the same time, the box building module 100 is allowed to have a proper adjustment space in the width direction (z direction) or the length direction (x direction). Thus, the positioning accuracy of the box-type building module 100 can be effectively improved, the building quality can be well improved, and the positioning operation of the box-type building module 100 on site is more convenient and flexible, so that the on-site workload is reduced, the labor intensity is reduced, and the building efficiency is improved.
