Description

Technical Field

[0001] The present invention relates to the field of building technology, and in particular to a modular building for farmhouses and a construction method thereof. Background Art

[0002] As demand for housing construction in rural areas continues to grow, shifting from basic living needs to a pursuit of high-quality, environmentally friendly, and efficient construction, modular prefabricated construction technology, as a modern construction method, offers a new direction for rural housing development with its unique advantages. It not only effectively addresses many of the challenges associated with traditional rural housing construction, such as long construction periods, significant resource waste, and inconsistent quality, but also improves the overall quality of rural housing.

[0003] Currently, modular buildings used for rural housing are divided into multiple prefabricated modules, precisely manufactured in factories and then transported to on-site assembly. However, traditional frame joint casting construction often results in exposed rebar and a heavy workload. Furthermore, there is insufficient space for later binding of rebar between modules, making connections difficult and impacting construction efficiency. Furthermore, rural areas lack professional construction teams, and existing construction workers are unfamiliar with prefabricated construction techniques and lack relevant skills training, making it difficult to ensure the quality of joint construction.

[0052] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0053] Example 1:

[0054] like Figure 1 、 Figure 2 and Figure 4 As shown, this embodiment provides a modular building for farmhouses, comprising a concrete module 1, a transverse module connection structure 2, and an upper and lower module connection structure 3. The transverse module connection structure 2 and the upper and lower module connection structure 3 are used to connect the modules, reducing the complexity of the connection between the modules.

[0055] like Figure 1 As shown, each floor of concrete modules 1 includes six concrete modules 11 arranged horizontally and vertically, in two rows and three columns. The left two columns of concrete modules 11 form a group of four adjacent concrete modules 11, and the right two columns of concrete modules 11 form a group of four adjacent concrete modules 11. It is understood that the middle column of concrete modules 11 forms a group of four adjacent concrete modules 11 with the concrete modules 11 on its left and right. Of course, this embodiment is merely an example. A floor of concrete modules 1 can have only four concrete modules 11 in two rows and two columns, nine concrete modules 11 in three rows and three columns, twelve concrete modules 11 in three rows and four columns, sixteen concrete modules 11 in four rows and four columns, and so on. Furthermore, more than two floors of concrete modules 1 are also possible. The present invention is particularly beneficial for farmhouses consisting of two or three floors of concrete modules 1.

[0056] Each concrete module 11 is a hexahedral prefabricated component consisting of a top plate 111, a bottom plate 112, four side plates 113, four crossbeams 114, and four columns 115. The bottom of the top plate 111 is connected to the tops of the four crossbeams 114. A rectangular through-groove 1111, with a depth no greater than the thickness of the top plate 111 and a width no greater than the width of the crossbeams 114, extends from the connecting edge of each pair of adjacent concrete modules 11. The columns 115 contain a plurality of vertically arranged structural ribs 1151 extending vertically from the upper edges of the columns 115. The top plate 111 of each concrete module 11 is located on top of the crossbeams 114, unlike conventional crossbeam placement. This arrangement eliminates the need for structural ribs to avoid interference, thus simplifying the connection between modules. The phrase "each pair of adjacent concrete modules 11" refers to each pair of adjacent concrete modules 11 in a row and each pair of adjacent concrete modules 11 in a column. It should be noted that the rectangular through-grooves 1111 extend along the connecting edges of the top plate 111 and the crossbeam 114 on adjacent sides of two adjacent concrete modules 11, creating a space for pouring concrete. The presence of the rectangular through-grooves 1111 along the length of the top plate 111 is slightly different from traditional modules, facilitating subsequent concrete pouring and improving the integrity of the individual modules.

[0057] As a preferred embodiment of the present invention, each column 115 includes four structural ribs 1151 arranged in a matrix.

[0058] In order to facilitate the overall pouring of farmhouses and improve their stability, Figure 1 As shown, the concrete module 1 further includes a building top plate 12 , which is disposed on the top of the top concrete module 1 .

[0059] The transverse module connection structure 2 is used to connect adjacent modules on the left and right, and front and back, to reinforce the connection between adjacent concrete modules 11. Figure 11As shown, the transverse module connection structure 2 is arranged in a rectangular groove 1111 and includes transverse plate reinforcement 21, longitudinal reinforcement ribs 22, and connecting reinforcement ribs 23. The transverse plate reinforcement 21 is arranged horizontally, with one end anchored in the top plate 111 and the other end extending horizontally from the edge of the top plate 111. The longitudinal reinforcement ribs 22 are arranged vertically, with the bottom end anchored in the crossbeam 114 and the top end extending vertically from the upper edge of the crossbeam 114. The rectangular groove 1111 is used to accommodate the extended transverse plate reinforcement 21 and longitudinal reinforcement ribs 22. The connecting reinforcement ribs 23 connect the extended transverse plate reinforcement 21 and longitudinal reinforcement ribs 22 of adjacent concrete modules 11. Because the rectangular groove 1111 forms a pouring space, pouring concrete in the rectangular groove 1111 can form an integral connection. This further improves the integrity of the module, while reducing the difficulty of on-site reinforcement binding and improving the overall quality of the reinforcement binding.

[0060] It should be noted that the connecting reinforcement 23 can be connected to the transverse plate reinforcement 21 and the longitudinal reinforcement 22 one-to-one or one-to-many, as long as it can connect the transverse plate reinforcement 21 and the longitudinal reinforcement 22 extending from adjacent concrete modules 11.

[0061] Preferably, multiple transverse plate reinforcements 21 are arranged adjacently and spaced apart within the top plate 111 along the extending direction of the connecting edge, and multiple longitudinal reinforcements 22 are arranged adjacently and spaced apart within the crossbeam 114 along the extending direction of the connecting edge. The transverse plate reinforcements 21 and longitudinal reinforcements 22 can be arranged crosswise, in contact with each other, or spaced apart. The connecting reinforcements 23 are connected to the transverse plate reinforcements 21 and longitudinal reinforcements 22 in a one-to-one correspondence. The crosswise arrangement of the transverse plate reinforcements 21 and longitudinal reinforcements 22 disperses local stress concentrations, effectively preventing concrete cracking.

[0062] As a preferred embodiment of the present invention, in order to improve the ability to resist wind loads and earthquakes, and at the same time facilitate rapid installation, such as Figure 11 As shown, the transverse plate reinforcement 21 is U-shaped, with the open end of the transverse plate reinforcement 21 anchored in the top plate 111 and the closed end of the transverse plate reinforcement 21 extending horizontally outward. The longitudinal reinforcement ribs 22 are U-shaped, with the open end of the longitudinal reinforcement rib 22 anchored in the crossbeam 114 and the closed end of the longitudinal reinforcement rib 22 extending vertically upward. The connecting reinforcement ribs 23 are ring-shaped and pass through the closed ends of the corresponding transverse plate reinforcement 21 and longitudinal reinforcement rib 22.

[0063] As a preferred embodiment of the present invention, the distance between two adjacent transverse plate reinforcement bars 21 is 300 mm, and the distance between two adjacent longitudinal reinforcement bars 22 is 300 mm.

[0064] In order to connect multiple transverse plate reinforcements 21, longitudinal reinforcements 22 and connecting reinforcements 23 in series, as shown in FIG. Figure 6 and Figure 11As shown, the transverse module connection structure 2 also includes at least one straight reinforcement rib 24, which is arranged along the length direction of the rectangular through groove 1111. The straight reinforcement rib 24 connects the transverse plate steel bars 21, the longitudinal reinforcement ribs 22 and the connecting reinforcement ribs 23 connected to the same concrete module 11. The straight reinforcement rib 24 is connected to the straight sections or curved sections of the transverse plate steel bars 21, the longitudinal reinforcement ribs 22 and the connecting reinforcement ribs 23 to improve the mechanical properties of the concrete module 11, the construction efficiency and the seismic resistance of the house.

[0065] As a preferred embodiment of the present invention, the number of straight reinforcing ribs 24 in a transverse module connecting structure 2 is two.

[0066] In actual application, the connection methods of the transverse plate steel bars 21, the longitudinal reinforcement bars 22, the connecting reinforcement bars 23 and the straight reinforcement bars 24 include but are not limited to binding or welding, as long as the transverse plate steel bars 21, the longitudinal reinforcement bars 22, the connecting reinforcement bars 23 and the straight reinforcement bars 24 can be fixedly connected.

[0067] like Figure 3 and Figure 7 As shown, the upper and lower module connection structures 3 simultaneously connect the corresponding upper and lower structural ribs 1151 to connect the two adjacent layers of concrete modules 1, reducing the difficulty of grouting and improving the connection strength between the modules. It should be noted that the upper and lower module connection structures 3 can simultaneously connect the four upper, lower, left, and right concrete modules 11 in two adjacent layers of concrete modules 1.

[0068] In order to accurately position and efficiently install each layer of concrete module 1, Figure 2 、 Figure 3 and Figure 4 As shown, the upper and lower module connection structure 3 includes a middle connection unit 31 and a side connection unit 32 .

[0069] Specifically, the intermediate connecting units 31 connect the corresponding upper and lower structural ribs 1151 at the intersections of four concrete modules 11 arranged horizontally and vertically. In this embodiment, there are two sets of "intersections of four adjacent concrete modules 11 arranged horizontally and vertically," and there are only two layers of concrete modules 1. Therefore, as shown in the figure, two intermediate connecting units 31 are provided in this embodiment. The side connecting units 32 connect the corresponding upper and lower structural ribs 1151 at the sides of the concrete modules 1 to connect the two adjacent layers of concrete modules 1. In this embodiment, there are only two layers of concrete modules 1, each layer having two rows and three columns of concrete modules 11, so there are a total of six side connecting units 32.

[0070] Specifically, if Figure 3 and Figure 8The intermediate connection unit 31 includes at least one horizontally arranged octagonal stirrup 311, at least two horizontal and vertical rectangular stirrups 312, and a plurality of vertically arranged first grouting sleeves 314. The octagonal stirrup 311 connects the structural reinforcement 1151 of the outer ring at the cross intersection of the concrete module 1. The horizontal and vertical rectangular stirrups 312 connect the structural reinforcement 1151 on the adjacent sides of two adjacent concrete modules 11. Both horizontal and vertical rectangular stirrups 312 are connected to the octagonal stirrup 311. The first grouting sleeve 314 is pre-embedded in the lower end of the column 115. The lower end of the first grouting sleeve 314 is flush with the lower end of the column 115. The first grouting sleeve 314 is coaxially connected to the corresponding structural reinforcement 1151 above and below, and corresponds one-to-one. The first grouting sleeve 314 can grout to connect the two adjacent layers of concrete modules 1 above and below.

[0071] Furthermore, in order to improve the connection strength between modules, Figure 3 As shown, there are two octagonal stirrups 311 and four horizontal and vertical rectangular stirrups 312. The intermediate connecting unit 31 also includes multiple first shear bars 313. Every two horizontal and vertical rectangular stirrups 312 are connected to one octagonal stirrup 311. The two octagonal stirrups 311 are vertically spaced apart. The multiple first shear bars 313 are adjacently spaced apart in the horizontal direction, and the first shear bars 313 connect the vertically spaced horizontal and vertical rectangular stirrups 312.

[0072] As a preferred embodiment of the present invention, the two octagonal stirrups 311 are vertically spaced 100 mm apart, and the number of the first shear bars 313 is 12.

[0073] Specifically, if Figure 4 and Figure 10 As shown, the side connection unit 32 includes at least two horizontally arranged rectangular stirrups 321 and a plurality of vertically arranged second shear bars 322 and a second grouting sleeve 323. The rectangular stirrups 321 connect the structural bars 1151 at the side of the concrete module 1 and are arranged at intervals in the vertical direction. The plurality of second shear bars 322 are arranged adjacently and spaced apart in the horizontal direction, and the second shear bars 322 connect the vertically spaced rectangular stirrups 321. The second grouting sleeve 323 is pre-embedded in the lower end of the column 115. The lower end of the second grouting sleeve 323 is flush with the lower end of the column 115. The second grouting sleeve 323 is coaxially connected to the corresponding structural bars 1151 above and below and corresponds one to one. The second grouting sleeve 323 can grout to connect two adjacent layers of concrete modules 1 above and below.

[0074] As a preferred embodiment of the present invention, the two rectangular stirrups 321 are vertically spaced 100 mm apart, and the number of the second shear bars 322 is 8.

[0075] Among them, in order to facilitate construction, the first shear reinforcement 313 and the second shear reinforcement 322 have the same structure. The first shear reinforcement 313 and the second shear reinforcement 322 both include a 180° hook section, a straight reinforcement section and a 90° right-angle hook section, wherein the bending direction of the 180° hook section is opposite to that of the 90° right-angle hook section.

[0076] The first grouting sleeve 314 and the second grouting sleeve 323 have the same structure. In order to make the slurry evenly fill the first grouting sleeve 314 and the second grouting sleeve 323, as shown in FIG. Figure 7 As shown, the side walls of the first grouting sleeve 314 and the second grouting sleeve 323 are both provided with a grouting hole 3141 and a slurry outlet hole 3142, wherein the grouting hole 3141 is located below the slurry outlet hole 3142, and grouting is performed from the grouting hole 3141. When the slurry can flow out evenly from the slurry outlet hole 3142, grouting is stopped, and then the grouting hole 3141 and the slurry outlet hole 3142 are sealed.

[0077] like Figure 5 As shown, the modular building for farmhouses also includes a top-level connection assembly 4. This assembly includes a top-level intermediate connection unit 41 and a top-level side connection unit 42. It should be noted that the top-level intermediate connection unit 41 is similar in structure to the intermediate connection unit 31, except that it lacks the first grouting sleeve 314. The remaining structures are identical. The top-level side connection unit 42 is similar in structure to the side connection unit 32, except that it lacks the second grouting sleeve 323. This eliminates the need for secondary grouting in the top-level connection assembly 4, improving the assembly efficiency of the farmhouse.

[0078] In order to improve the convenience of pouring construction, Figure 1 and Figure 10 As shown, the modular building for farmhouses also includes a formwork assembly 5. The formwork assembly 5 includes a formwork 51, multiple fixing screws 52, and multiple embedded nuts (not shown). The multiple embedded nuts are embedded in the concrete module 11, with their outer end faces flush with the outer surface of the concrete module 11. The embedded nuts are threaded, and the fixing screws 52 are threaded to match the embedded nuts. The multiple fixing screws 52 correspond one-to-one with the multiple embedded nuts. The formwork 51 is arranged vertically and connected to the side of the concrete module 1 via the multiple fixing screws 52 and multiple embedded nuts.

[0079] In order to reinforce the template 51, such as Figure 10 As shown, the template assembly 5 also includes a mounting nut 53, which is arranged on the outside of the template 51. The mounting nut 53 is provided with a thread matching the fixing screw 52, and multiple mounting nuts 53 correspond to multiple fixing screws 52 one by one.

[0080] This embodiment also provides a method for constructing a two-story farmhouse, using the modular building for farmhouses described above, and comprising the following steps in sequence:

[0081] Step 1:

[0082] Each concrete module 11 in the concrete module 1 on the bottom floor is hoisted and calibrated;

[0083] Step 2:

[0084] Connect the upper and lower module connection structures 3 to the structural reinforcement 1151 in the current construction layer;

[0085] Step 3:

[0086] Fill the gaps between the adjacent sides of each two adjacent concrete modules 11 in the current construction layer with rubber strips and sealant, and then use connecting reinforcement bars 23 to connect the transverse plate reinforcement bars 21 and longitudinal reinforcement bars 22 extending from the adjacent concrete modules 11;

[0087] Step 4:

[0088] Pour concrete at the rectangular groove 1111 and the upper and lower module connection structures 3 to connect the concrete modules 11 in the current construction layer into a whole;

[0089] Step 5:

[0090] Each concrete module 11 of the new layer of concrete module 1 is hoisted and aligned above the current construction layer. The upper and lower module connection structures 3 connected with the structural reinforcement 1151 are connected to the structural reinforcement 1151 of the corresponding new layer of concrete module 1, and grouting is performed on the upper and lower module connection structures 3;

[0091] The new layer of concrete module 1 is the top layer, and the new layer of concrete module 1 is used as the current construction layer. The structural reinforcement 1151 in the current construction layer is connected to the top layer connection component 4. Repeat step 3, then hoist and accurately install the building top plate 12 and calibrate the positioning, grout the connection between the building top plate 12 and the current construction layer, and pour concrete on the whole to form a farmhouse.

[0092] Example 2:

[0093] like Figure 6 As shown, the rest of the structure of this embodiment is the same as that of embodiment 1, except that this embodiment provides a three-story modular farmhouse building, including three layers of concrete modules 1, and each layer of concrete modules 1 has two rows and three columns of concrete modules 11.

[0094] It should be noted that this embodiment provides a three-story modular farmhouse building, but it can also be a multi-story modular farmhouse building. In addition, the modular building of the present invention can also be used for construction of temporary houses, etc.

[0095] This embodiment also provides a method for constructing a farmhouse, using the modular building for a farmhouse, and comprising the following steps in sequence:

[0096] Step 1:

[0097] Each concrete module 11 in the concrete module 1 on the bottom floor is hoisted and calibrated;

[0098] Step 2:

[0099] Connect the upper and lower module connection structures 3 to the structural reinforcement 1151 in the current construction layer;

[0100] Step 3:
