[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] The present application embodiment discloses a device for assembling and splicing prefabricated primary and secondary beams of a house, such as Figure 1 and 2 As shown, it includes a construction frame 1 and a formwork mechanism 3. The frame is provided with a fixed frame 11, an intermediate frame 12 and an adjustable frame 13. The fixed frame 11 and the adjustable frame 13 are respectively located on opposite sides of the intermediate frame 12. The fixed frame 11 and the adjustable frame 13 are respectively provided for placing a main beam 2, and the intermediate frame 12 is provided for placing a secondary beam 21. The formwork mechanism 3 is used to build a casting space enclosure at each connection point between the main beam 2 and the secondary beam 21. In this embodiment, the single-spliced ​​beam frame includes two main beams 2 and three secondary beams 21. The two main beams 2 are parallel and side by side. The three secondary beams 21 are located between the two main beams 2. The length direction of the secondary beam 21 is perpendicular to the length direction of the main beam 2. The upper surfaces of the main beam 2 and the secondary beam 21 are flush, but the lower side of the main beam 2 is lower than the lower side of the secondary beam 21. The side walls of the main beam 2 and the ends of the secondary beam 21 are fixedly connected with embedded steel plates 22 in a pre-embedded manner. The embedded steel plates 22 of the main beam 2 and the secondary beam 21 are overlapped with each other and fixedly connected by bolts and nuts. The plate surface of the embedded steel plate 22 is perpendicular to the length direction of the main beam 2, and the length direction of the bolts passing through it is parallel to the length direction of the main beam 2. The embedded steel plate 22 and the bolts and nuts thereon are all located in the casting space.

[0032] like Figure 1 and 3 As shown, the number of the intermediate frames 12 is consistent with the number of the secondary beams 21 and the two correspond one to one, the fixed frame 11 and the intermediate frame are fixedly connected to the construction frame 1, and the adjustment frame 13 is slidably connected to the construction frame 1, and the sliding direction is close to or away from the fixed frame 11. The fixed frame 11 and the adjustment frame 13 are both provided with a lifting platform 16 that slides in the vertical direction, and the lifting platform 16 is rotatably connected with a plurality of main adjusting rollers 14, and the arrangement direction of the plurality of main adjusting rollers 14 is the length direction of the main beam 2, and the rotation axis of the main adjusting roller 14 is consistent with the length direction of the secondary beam 21. Both the fixed frame 11 and the adjustable frame 13 are provided with adjustment holes 18, and the lifting platform 16 is located in the adjustment hole 18. The opening direction of the adjustment hole 18 is also in the vertical direction. During the up and down movement of the lifting platform 16, the opening of the adjustment hole 18 is provided for the main adjusting roller 14 to pass through. After the main adjusting roller 14 moves up and passes through the adjustment hole 18, it abuts against the bottom of the main beam 2 and lifts up the main beam 2. The main beam 2 can then move along its own length direction on the fixed frame or the adjustable frame 13 through the main adjusting roller 14.

A force-bearing wedge 161 is fixedly connected to the lifting platform 16, and the wedge surface of the force-bearing wedge 161 abuts against the wedge surface of the control wedge 172. The control screw 171 is rotatably connected to the fixed frame 11 or the adjustable frame 13, and the axis of the control screw 171 is parallel to the length direction of the main beam 2. The control wedge 172 is slidably connected to the fixed frame 11 or the adjustable frame 13, and the sliding direction is horizontal. The control wedge 172 is threadedly connected to the control screw 171. When the control screw 171 is rotated to move the control wedge 172, the lifting platform 16 can be controlled to move up and down through the wedge surface.

[0034] like Figure 1 and 3 As shown, the intermediate frame 12 is rotatably connected with a plurality of secondary adjustment rollers 15, the arrangement direction of the plurality of secondary adjustment rollers 15 is consistent with the length direction of the secondary beam 21, the rotation axis of the secondary adjustment rollers 15 is perpendicular to the length direction of the secondary beam 21, and the roller surface is in contact with the bottom of the secondary beam 21; the secondary beam 21 placed on the intermediate frame 12 can slide along its own length direction through the secondary adjustment rollers 15, so as to be able to move itself close to the main beam 2. After the main beam 2 and the secondary beam 21 are placed on the corresponding fixed frame 11 or the intermediate frame 12 or the adjustment frame 13, the position of the main beam 2 along its own length direction is first changed, and then the lifting platform 16 is lowered, and the main beam 2 cannot be easily moved. Then, the secondary beam 21 is pushed to make it close to the main beam 2 on the fixed frame 11, and the main beam 2 on the adjustment frame 13 is pushed to make it close to the secondary beam 21. When the embedded steel plates 22 at each connection point are aligned, the fixed connection operation can be performed by bolts.

[0035] like Figure 1 , 2As shown in Figures 4 and 5 , the formwork mechanism 3 includes a bottom plate 31, two side plates 32 and a top plate 33 at a single connection position between the main beam 2 and the secondary beam 21. The bottom plate 31 is located below the embedded steel plate 22, the top plate 33 is located above the embedded steel plate 22, and the two side plates 32 are located on opposite sides of the embedded steel plate 22. Auxiliary clamps 4 are provided on both the fixed frame 11 and the adjustable frame 13. The auxiliary clamps 4 are used to temporarily fix the bottom plate 31 and make the bottom plate 31 abut against the main beam 2 and the secondary beam 21. The edge of the bottom plate 31 is integrally formed with a mounting wing 311. The auxiliary clamps 4 include a mounting shaft 41. The mounting shaft 41 is rotatably connected to the fixed frame 11 or the adjustable frame 13. The mounting shaft 41 is located on the side of the main beam 2 facing the secondary beam 21, and is located at a height lower than the lower surface of the secondary beam 21. The rotation axis is parallel to the length direction of the main beam 2. A mounting slot 411 is provided on the side wall of the mounting shaft 41, and the depth direction of the mounting slot 411 is the radial direction of the mounting shaft 41. A mounting plug 312 is fixedly connected to the mounting wing 311. After the mounting plug 312 is inserted into the mounting slot 411, the bottom plate 31 can rotate relying on the mounting shaft 41; when the mounting shaft 41 rotates until the mounting wing 311 and the side of the main beam 2 facing the secondary beam 21 abut, the bottom plate 31 and the bottom side of the secondary beam 21 abut, and at this time, the plate surface of the bottom plate 31 is a horizontal plane. A locking hole 412 is coaxially opened on the mounting shaft 41, and the locking hole 412 is connected to the mounting slot 411. A connecting hole 3121 is opened on the side of the mounting plug block 312, and the connecting hole 3121 is aligned and connected with the locking hole 412. A clamp pin 42 is passed through the locking hole 412 on the mounting shaft 41, and the end of the clamp pin 42 is inserted into the connecting hole 3121. At this time, the mounting plug block 312 cannot be detached from the mounting slot 411, and the connection stability between the base plate 31 and the mounting shaft 41 is relatively high.

[0036] like Figure 2 , 4As shown in Figure 5, a matching wing 321 is integrally formed on one side edge of the side plate 32, the plate surface of the side plate 32 abuts against the side wall of the secondary beam 21, and the matching wing 321 abuts against the side of the main beam 2 facing the secondary beam 21. The formwork mechanism 3 also includes an assembly sleeve 34 and a tension bolt 341, the tension bolt 341 passes through the assembly sleeve 34, the top plate 33 and the bottom plate 31, and abuts against the opposite plate surfaces of the top plate 33 and the bottom plate 31 respectively; the side wall of the assembly sleeve 34 contacts and abuts against the plate surface of the side plate 32, and after the tension bolt 341 is tightened, the top plate 33 and the bottom plate 31 abut against the upper and lower edges of the side plate 32 respectively, and the two together with the assembly sleeve 34 form a fixed restriction on the side plate 32. An eccentric column 36 is rotatably connected to the bottom plate 31, and the rotation axis and length direction of the eccentric column 36 are perpendicular to the plate surface of the bottom plate 31. A centering groove 333 is provided on the top plate 33 for the top end of the eccentric column 36 to be inserted. After the top plate 33 and the bottom plate 31 clamp the side plate 32 together, the eccentric column 36 is located close to the matching wing edge 321; rotating the eccentric column 36 can make the side wall of the eccentric column 36 press against the side of the matching wing edge 321 away from the main beam 2, thereby achieving further compression of the side plate 32.

[0037] like Figure 4 and 5 As shown, the bottom plate 31 is provided with a stopper for stopping the eccentric column 36 from rotating. After the side wall of the eccentric column 36 abuts against the matching wing edge 321, the stopper is used to keep the eccentric column 36 stationary in this state. The stopper is a stopper pin 37, which passes through the mounting wing edge 311 and the mounting plug block 312 at the same time. Its penetration direction is perpendicular to the plate surface of the bottom plate 31. A stopper tension spring 38 is connected between the stopper pin 37 and the mounting wing edge 311; a stopper toothed ring 361 is coaxially fixedly connected to one end of the eccentric column 36 close to the bottom plate 31. In the natural state, the end of the stopper pin 37 is located on the side of the bottom plate 31 facing the top plate 33, and two of the serration gaps of the limiting toothed ring are used for the stopper pin 37 to be inserted, and the limiting toothed ring and the eccentric column 36 cannot rotate. A limiting hole 371 is provided on the side wall of the stop pin 37. When the stop pin 37 is pressed until it is completely within the mounting wing 311, the limiting hole 371 and the connecting hole 3121 are aligned, that is, the limiting hole 371 can be inserted by the clamp pin 42. At this time, the stop pin 37 cannot extend from the plate surface of the base plate 31, and the eccentric column 36 can rotate freely.

[0038] like Figure 1 and 2 As shown, the formwork mechanism 3 further includes a positioning screw barrel 35 and a positioning bolt 351. The positioning screw barrel 35 is welded and fixed to the side of the embedded steel plate 22 facing the top plate 33.

The positioning bolt 351 passes through the top plate 33 and is screwed into the positioning screw barrel 35. Grouting holes and exhaust holes 332 are provided on the top plate 33. After the formwork mechanism 3 is built and fixed, concrete is poured into the interior thereof through the grouting holes and the exhaust holes 332. The exhaust holes 332 are threaded holes.

[0039] The implementation principle of the assembly and splicing device of the prefabricated primary and secondary beams of a house in the embodiment of the present application is as follows: First, hang each bottom plate 31 on the installation shaft 41, and pay attention to the clamp pin 42 to pass through the connecting hole 3121 and the limiting hole 371 at the same time; then the main beam 2 and the secondary beam 21 are hoisted to the corresponding position frame respectively, and the embedded steel plates 22 at various locations are connected and fixed after adjusting their respective positions; the fixed position of the positioning screw barrel 35 is determined by simulating the assembly template mechanism 3, the positioning screw barrel 35 is welded on the embedded steel plate 22, the top plate 33 is installed, and then the bottom plate 31 and the side plate 32 are connected based on the top plate 33. After the eccentric column 36 abuts against the matching wing edge 321, the clamp pin 42 is pulled out, and then the concrete can be poured. After the concrete fills its space, the exhaust hole 332 and the grouting hole are blocked, and it is left to stand for curing. After the curing is completed, the template mechanism 3 is removed, and the inner cavity of the positioning screw barrel 35 is blocked with filling material, and the beam frame assembly is completed.
