Description

Technical Field

[0001] The utility model relates to a building structure, in particular to a structure for connecting adjacent walls of adjacent prefabricated building units, which is suitable for use in assembled synthetic buildings. Background Art

[0002] Currently, prefabricated construction methods are becoming increasingly widely used, but the connection of adjacent prefabricated building units is a difficult and painful point in current construction. Under existing construction methods, a cast-in-place concrete area is provided between adjacent walls. Two adjacent prefabricated building units can be connected together by connecting steel bars and casting concrete in this cast-in-place concrete area. At both ends of this cast-in-place concrete area, due to the complex force and relatively weak structure, it is necessary to set up restraining connecting steel bars to strengthen the structural load. However, at the restraining steel bar area between the prefabricated building units, due to the narrow space, tying the steel bars is very inconvenient, and the construction efficiency is low. It is not as easy to operate as tying steel bars on site in cast-in-place construction, and it requires more manpower. Moreover, since the connecting wall of the prefabricated unit is a non-structural wall, the structural wall needs to be cast on the construction site. Under this solution, the building wall area increases, the occupied area increases, and the actual usable space of the building decreases, thereby reducing the construction efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a connection structure of a hybrid assembled building that is easy to construct and adds a connection structure in the steel bar constraint area so that the walls on both sides of the connection piece can also participate in the structural force.

[0004] The technical solution of the present utility model is as follows: A connection structure of a hybrid assembled composite building, comprising: a first connecting wall provided on a first prefabricated building unit, and a second connecting wall provided on a second prefabricated building unit; the first connecting wall and the second connecting wall are adjacent to each other and a cast-in-place concrete area is provided therebetween, with restraining steel bar areas provided at both ends of the cast-in-place concrete area;

[0005] At the restrained steel bar area, the first connecting wall is pre-embedded with a plurality of rows of vertically arranged partially exposed steel sheets, and the second connecting wall is pre-embedded with a plurality of rows of vertically arranged partially exposed steel bar hoops, the exposed portions of the steel sheets are provided with vertical through holes, and the steel sheets on the first connecting wall correspond horizontally to the steel bar hoops on the second connecting wall and are connected through a middle connecting piece;

[0006] The middle connecting member includes: a plurality of middle connecting plates arranged vertically, and a vertical rod fixedly connected to the plurality of middle connecting plates; the middle connecting plate is provided with two left and right connecting holes, which correspond vertically to the vertical through holes on the steel plate of the first connecting wall and the inner holes of the steel hoop of the second connecting wall respectively, and the steel plates and steel hoops on the left and right sides are connected to the middle connecting member by passing vertical serial steel bars through the connecting holes and vertical through holes on one side of the plurality of middle connecting plates and the connecting holes and inner holes of the steel hoop on the other side of the plurality of middle connecting plates.

[0007] The part of the steel sheet embedded in the wall is provided with a serial hole, and the part of each row of steel sheets embedded in the wall is connected together by vertical steel bars passing through the serial hole; the part of each row of steel bar hoops embedded in the wall is connected together by vertical steel bars passing through its inner hole.

[0008] The vertical rod passes through a central hole opened between the left and right connection holes of each intermediate connection piece and is fixed to the intermediate connection piece by welding.

[0009] Both side end surfaces of the middle connecting piece are arc-shaped.

[0010] The diameters of the connecting holes and the vertical through holes are in a range of 14 mm to 30 mm.

[0011] The steel bar hoop is made of steel bars with a diameter of not less than 10 mm, and the length of the steel bar hoop is 85-185 mm and the width is 95-105 mm.

[0012] Compared with the prior art, the connection structure and construction method of the hybrid assembled synthetic building of the present invention adopts an intermediate connecting plate with connection holes on both sides in the restrained steel bar area between two adjacent prefabricated building units, which are respectively connected with the steel plates and steel hoops of the connecting walls on both sides by vertical series steel bars. Therefore, the operation is simple and easy to implement during on-site construction, and will not be affected by narrow space. It can save labor, reduce construction costs, improve construction efficiency, and achieve the same effect as on-site steel bar tying in cast-in-place buildings; in addition, under normal circumstances, the first and second prefabricated building units of the two prefabricated building units are non-structural walls and do not bear structural forces. Only the middle cast-in-place part bears structural forces. After using the connection structure of the present invention, the non-structural walls on both sides can also participate in the structural forces, and the overall force is better, which can reduce the wall area, increase the building efficiency, and save costs.

[0025] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings.

[0026] like Figure 1 、 Figure 6 and Figure 7 As shown, the connection structure of the hybrid assembled synthetic building of the present invention includes: adjacent first connecting walls 11 and second connecting walls 21, steel sheets 51 and steel hoops 52 fixedly arranged on opposite sides of the first connecting walls 11 and the second connecting walls 21, and a middle connecting member 6 connected to the steel sheets 51 and steel hoops 52 on both sides.

[0027] In this embodiment, the first connecting wall 11 is arranged on the first prefabricated building unit 1 on the right, and the second connecting wall 21 is arranged on the second prefabricated building unit 2 on the left. The first connecting wall 11 and the second connecting wall 21 are adjacent to each other on the left and right, and a cast-in-place concrete area 3 is provided therebetween. The cast-in-place concrete area 3 is provided with restrained steel bar areas 4 at the front and rear ends.

[0028] The steel sheet 51, steel hoop 52 and middle connector 6 are arranged at the restrained steel bar area 4. Figure 2 and Figure 3 As shown, the side of the first connecting wall 11 facing the cast-in-place concrete area 3 is provided with several rows of steel sheets 51. Each row is composed of multiple steel sheets 51 arranged vertically at regular intervals. Similarly, the side of the second connecting wall 21 facing the cast-in-place concrete area 3 is also provided with several rows of vertically arranged steel hoops 52. Furthermore, the steel sheets 51 on the first connecting wall 11 and the steel hoops 52 on the second connecting wall 21 correspond horizontally one-to-one and are connected by a central connector 6.

[0029] The steel sheet 51 is partially embedded in the prefabricated wall and partially exposed. Figure 9 As shown, the exposed part of the steel sheet 51 is provided with a vertical through hole 511 with a diameter of 16 mm, and the part buried in the wall is provided with a through hole with a diameter of 24 mm. The part of each column of steel sheets 51 buried in the wall is connected together with vertical steel bars 8 passing through the through holes, which can strengthen the bonding strength between the steel sheet 51 and the wall. The thickness of the steel sheet 51 is 10 mm.

[0030] The steel bar hoops 52 are also partially embedded in the prefabricated wall and partially exposed. The part of each row of steel bar hoops 52 embedded in the wall is connected in series with vertical steel bars 8 passing through its inner holes. Figure 10 As shown, the steel bar hoop 52 is formed by bending steel bars with a diameter of not less than 10 mm, and has a length of 85 mm and a width of 100 mm.

[0031] like Figure 8 and Figure 11 As shown, the central connecting member 6 comprises: a plurality of intermediate connecting pieces 61 arranged vertically, and a vertical rod 62 fixedly connected to the plurality of intermediate connecting pieces 61. The intermediate connecting pieces 61 are provided with two left and right connecting holes 63 and a center hole 64 located between the two connecting holes 63. The vertical rod 62 passes through the center hole 64 of each intermediate connecting piece 61 and is welded to the intermediate connecting piece 61. In this embodiment, the intermediate connecting pieces 61 are generally elliptical in shape, with arc-shaped end surfaces on both sides, which makes it easier for the intermediate connecting piece 61 to rotate in a narrow space. The intermediate connecting piece 61 is 10 mm thick, the connecting holes 63 have a diameter of 16 mm, and the center hole 64 has a diameter of 12 mm. The vertical rod 62 is made of steel bars with a diameter of 10 mm.

[0032] like Figure 7 and Figure 12As shown, the left and right connecting holes 63 on the intermediate connecting piece 61 correspond vertically to the positions of the vertical through hole 511 of the steel sheet 51 on the first connecting wall 11 and the inner hole of the steel hoop 52 on the second connecting wall 21, respectively. The steel sheets 51 on the left and right sides, the steel hoop 52 and the middle connecting piece 6 are connected together by passing the vertical series steel bars 7 through the connecting holes 63 and the vertical through hole 511 on one side and through the connecting holes 63 and the inner hole of the steel hoop 52 on the other side. In this embodiment, the series steel bars 7 are threaded steel bars with a diameter of 14 mm. In the utility model, the embedded parts in the form of steel hoop 52 with a larger inner hole are provided on one side of the wall, which can greatly reduce the difficulty of aligning the series steel bars 7 and passing through the multiple intermediate connecting pieces 61 and steel hoop 52 arranged vertically, thereby ensuring smooth construction.

[0033] Of course, the sizes of the steel sheets 51, steel hoops 52, intermediate connecting pieces 61, vertical rods 62, and connecting steel bars 7 can be adjusted accordingly according to the wall thickness, the thickness of the cast-in-place concrete area 3, the magnitude of the force, etc.

[0034] The construction method of the connection structure of the hybrid assembled building of the utility model comprises the following steps:

[0035] Step 1: Figure 2 and Figure 3 As shown, the first prefabricated building unit 1 is hoisted to the set position and fixed, and the front and rear ends of the first connecting wall 11 are provided with exposed steel sheets 51;

[0036] Step 2: Figure 4 and Figure 5 As shown, after the vertical connecting steel bars 7 are passed through the vertical through-holes 511 of the steel sheet 51 of the first connecting wall 11 and the connecting hole 63 on the right side of the middle connecting member 6, the middle connecting member 6 is rotated to one side so that the connecting hole 63 on the other side is close to the first connecting wall 11;

[0037] Step 3: hoist the second prefabricated building unit 2 to the set position and fix it, with exposed steel hoops 52 provided at the front and rear ends of the second connecting wall 21;

[0038] Step 4: Figure 6 and Figure 7 As shown, after rotating the middle connecting member 6 so that the connecting hole 63 on one side is perpendicular to the inner hole of the steel hoop 52 on the second connecting wall 21, vertical series steel bars 7 are passed through the connecting hole 63 on this side and the inner hole of the steel hoop 52, thereby connecting the prefabricated building units on the left and right sides.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
