DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] like Figure 1-17 As shown, an embodiment of the present invention provides a set of components for a building roof installation frame, including an upper beam 1, a lower beam 4, a side connecting rod 5, a herringbone frame 2 with an upper installation port, and a connecting beam 6 with side clamps 602 installed at both ends, the upper installation port is located at the middle position of the upper structure of the herringbone frame 2 and an insertion port penetrating downward is provided at the bottom, each herringbone frame 2 is connected in series at both ends through the side connecting rod 5, the upper beam 1, the lower beam 4, the side connecting rod 5, the herringbone frame 2 and the connecting beam 6 are all integrally processed from light steel, one side of the side connecting rod 5 is provided with the same number of first connecting holes as the herringbone frame 2 and equidistantly distributed, the two ends of the lower part of the herringbone frame 2 are horizontal hook-shaped, and a support locking assembly 3 is distributed between the herringbone frame 2 and the connecting beam 6. The support locking assembly 3 includes an outer cylinder 302 and a seat cylinder 303 fixed at both ends of the outer cylinder 302 and with a blade 308 on the inner wall, and the outer cylinder 302 at both ends of the support locking assembly 3 is limited by a lower spring assembly and an upper spring assembly respectively.

[0045] An upper connecting assembly 7 is installed in the upper installation port, and the upper connecting assembly 7 is vertically inserted into the upper installation port. The upper beam 1 is connected to multiple herringbone frames 2 arranged in parallel, and the lower part is inserted into the inner side of the upper connecting assembly 7 and locked. The lower part of the upper connecting assembly 7 includes a fixedly connected shell and a fixing frame 707, and the fixing frame 707 extends downward into the insertion port. An upper spring assembly is installed inside the fixing frame 707, and the upper spring assembly includes an upper clamping seat 706 and a sixth spring 708. The upper clamping seat 706 is slidably connected inside the fixing frame 707. The sixth spring 708 is fixedly connected between the upper clamping seat 706 and the fixing frame 707. The lower side wall of the shell is provided with an upper through hole. The upper end of the upper clamping seat 706 extends out of the lower side wall of the shell from the upper through hole, and the lower end is clamped on both sides of the seat tube 303 at the upper end of the support locking assembly 3. The upper beam 1 is in contact with the shell, and a connecting port is provided on the side facing the inner bottom surface of the shell. When the upper beam 1 is locked by the upper connecting assembly 7, the upper part of the upper clamping seat 706 extends into the connecting port, thereby limiting the movement of the upper beam 1 along the length direction.

[0046] The two ends of the herringbone frame 2 are slidably connected to the inner side of the side clamp 602, and the side clamp 602 locks the side connecting rod 5 and the side clamp 602, the side clamp 602 and the connecting beam 6, and the herringbone frame 2 and the connecting beam 6, so that the herringbone frame 2, the side clamp 602 and the connecting beam 6 can be connected to improve the integrity, and the horizontal hook-shaped ends at both ends of the herringbone frame 2 slide into the side clamp 602 in the horizontal direction.

[0047] The side clamp 602 also includes a connecting shell, a support rod 6021, a limiting column 6027, a third spring 6024, a push rod 6025 and a wedge 6026. The connecting shell is installed in the end of the connecting beam 6. The side of the connecting shell away from the center of the connecting beam 6 is C-shaped. The horizontal hook-shaped ends at both ends of the herringbone frame 2 are hooked at the C-shaped part of the connecting shell. A horizontal and square inner cavity is arranged in the connecting shell. The push rod 6025 is composed of a large diameter part and a small diameter part perpendicular to each other. The large diameter part of the push rod 6025 is slidably connected to the inner cavity. The large diameter part of the push rod 6025 is connected to the side wall of the connecting shell toward the middle of the connecting beam 6 through the third spring 6024. The third spring 6024 is a compression spring. The push rod 6025 is pushed to the side away from the center of the connecting beam 6 by the action of the third spring 6024. The push rod 6025 A wedge block 6026 is fixed on the upper side of the small diameter part and the end portion passes through the side wall of the connecting shell and extends into the side connecting rod 5, that is, a second connecting hole for the small diameter part of the push rod 6025 to pass through is provided in the middle position of the C-shaped part of the connecting shell. When the first connecting hole and the second connecting hole of the side connecting rod 5 are coaxial, the third spring 6024 can push the small diameter part of the push rod 6025 to pass through the second connecting hole and extend into the first connecting hole of the side connecting rod 5, thereby realizing the connection between the side clamp 602 and the side connecting rod 5, and at the same time, it can also limit the rotation of the side connecting rod 5 along the axial direction. The lower part of the limiting column 6027 cooperates with the inclined surface of the wedge block 6026. When the wedge block 6026 moves with the push rod 6025, it will have a thrust on the limiting column 6027. The lower part of the limiting column 6027 that cooperates with the inclined surface of the wedge block 6026 is also wedge-shaped.

[0048] The support rod 6021 is fixedly connected to the lower side surface of the limiting column 6027 and at the position outside the wedge block 6026, that is, the support rod 6021 is located on both sides of the part where the limiting column 6027 and the wedge block 6026 cooperate. The small diameter part of the push rod 6025 passes through the inner side of the support rod 6021 and at the position below the part where the limiting column 6027 and the wedge block 6026 cooperate. The size of the limiting column 6027 gradually increases upward, and the corresponding taper is 1:11. The connecting beam 6 and the herringbone frame 2 are respectively fixed with a lower pressure ring 6029 and an upper pressure ring 6028 made of fluororubber at the position directly above the limiting column 6027. The inner wall of the lower pressure ring 6029 is cylindrical, and its diameter is equal to the small diameter of the part where the limiting column 6027 connects to the support rod 6021. The inner diameter of the pressure ring 6028 gradually increases from bottom to top, and the taper is 1:9, that is, the lower pressure ring 6029 and the upper pressure ring 6028 will exert downward pressure on the limit column 6027. Therefore, when there is no support on the lower side of the support rod 6021, due to the obstruction of the lower pressure ring 6029, the limit column 6027 presses the wedge block 6026 so that the push rod 6025 pushes the third spring 6024 to be compressed toward the middle position of the connecting beam 6, and then the small diameter part of the push rod 6025 is in the second connecting hole and does not extend into the C-shape of the connecting shell, and thus will not hinder the connection between the A-frame 2 and the connecting beam 6. When the support rod 6021 is pushed up to drive the limit column 6027 to move upward, the limit column 6027 is resisted by the lower pressure ring 6029 and the upper pressure ring 6028.

[0049] A cavity 311 is provided on the upper side of the middle part of the connecting beam 6, and a lower spring assembly is installed inside the cavity 311. The lower spring assembly limits the lower beam 4. The lower spring assembly includes a lower clamping seat 312 and a second spring 310. The lower clamping seat 312 is slidably connected to the cavity 311. The second spring 310 is fixedly connected between the lower inner wall of the cavity 311 and the lower clamping seat 312. A connecting groove is provided on the upper side surface of the lower beam 4, that is, the lower part of the lower clamping seat 312 extends through the side wall of the connecting beam 6 below the cavity 311 and is connected to the connecting groove, thereby limiting the movement of the lower beam 4 along the length direction.

[0050] The lower end of the lower clamping seat 312 extends into the lower beam 4 and the two ends of the upper part are clamped on both sides of the seat tube 303 at the lower end of the support locking assembly 3. After the lower clamping seat 312 on both sides of the seat tube 303 at the lower end of the support locking assembly 3 is pulled up, the action force of the second spring 310 can be overcome to drive the lower clamping seat 312 to move upward, and then the structure under the lower clamping seat 312 moves upward. After the lower clamping seat 312 moves upward, the lower beam 4 can be connected to the connecting beam 6. The lower beam 4 slides through the connecting opening set in the middle of the connecting beam 6, which can limit the rotation of the lower beam 4 in the connecting opening.

[0051] The inner wall of the seat tube 303 is provided with a first inner groove, and the middle part of the outer tube 302 is provided with an inflation head 301, which is used to be connected to the inflation device tube. Both sides of the inflation head 301 are connected with spiral extension airbags 305. After the inflation device inflates the inflation head 301 through the pipeline, the gas will penetrate into the spiral extension airbag 305. Before inflation, the spiral extension airbag 305 is in a twisted and compressed state. During the inflation process of the spiral extension airbag 305, the spiral extension airbag 305 rotates and extends at the same time. The spiral extension airbag 305 is made of two layers of polyamide fabric sandwiching a steel wire rope. When the spiral extension airbag 305 is in a twisted and compressed state, the steel wire rope is in a spiral state. The diameter of the steel wire rope is 5 mm, and the thickness of the two layers of polyamide fabric is 05 mm, the other end of the spiral extension airbag 305 is fixedly connected with a transition plate 306, the transition plate 306 is disc-shaped, the other side of the transition plate 306 is fixedly connected with a concrete slurry bag 315 and a connecting rod 309 passing through the concrete slurry bag 315, the side of the connecting rod 309 is fixedly connected with two side plates distributed at 180 degrees and located in the concrete slurry bag 315, the concrete slurry bag 315 is filled with concrete with a retarder and a water reducer, the other end of the connecting rod 309 is fixedly connected with a hook plate 316, the seat tube 303 is provided with a channel 313 on the side away from the outer tube 302, the inner wall of the channel 313 is provided with a second inner groove, the channel 313 and the hook plate 316 are distributed up and down, after the spiral extension airbag 305 is extended, the transition plate is pushed 306 makes the connecting rod 309 drive the hook plate 316 away from the inflation head 301 and rotate with the transition plate 306. The lower side wall of the fixing frame 707 and the side wall of the connecting beam 6 above the cavity 311 are both provided with a guide port 314 which is connected to the channel 313 and guides the hook plate 316. After passing through the guide port 314, the upper and lower hook plates 316 respectively enter the space where the sixth spring 708 and the second spring 310 are located. After the hook plate 316 rotates further, it hooks the fixing frame 707 and the side wall of the connecting beam 6 on the upper side of the cavity 311, respectively, thereby realizing the connection between the support locking assembly 3 and the upper connecting assembly 7, and the locking of the support locking assembly 3 and the connecting beam 6. Since the concrete slurry bag 315 is driven by the transition plate 306 to enter the seat tube 303 , is cut by the blade 308 in the seat tube 303, and then the concrete enters the space inside the seat tube 303 and is filled into the first inner groove and the second inner groove. An elastic pushing component acting on the concrete slurry bag 315 is provided at the side of the seat tube 303 away from the outer tube 302. Through the action of the elastic pushing component, the concrete slurry bag 315 is pushed into the outer tube 302 before the spiral extension airbag 305 is inflated. The elastic pushing component is composed of a first spring 304 fixed to the inner wall of the seat tube 303 away from the outer tube 302 and a top plate 307 fixed to the other end of the first spring 304. The top plate 307 is sleeved on the outside of the connecting rod 309, and the top plate 307 is located within the range of the cylindrical surface of the blade 308 away from the seat tube 303.This can prevent the top plate 307 from hitting the blade 308.

[0052] An insertion head 601 is fixedly connected to the lower side of both ends of the connecting beam 6, and the lower part of the side clamping head 602 includes two clamping components located above the insertion head 601 and close to each other.

One end of the torsion spring is fixedly connected to the connecting shell, and the other end is fixedly connected to the arc-shaped card. Under the action of the torsion spring, the two arc-shaped cards are brought close to the middle part of the insertion head 601. After the support column with an annular groove on the upper end is inserted into the insertion head 601, the upper end of the support column first opens the arc-shaped card, and then the arc-shaped card is reset and clamped in the annular groove by the torsion spring.

[0053] Both side structures of the herringbone frame 2 are provided with two connecting components 21 for connecting the tensioning units. The tensioning units corresponding to the two adjacent herringbone frames 2 are cross-distributed up and down and the corresponding connecting components are inverted with each other.

The tensioning unit connects the two connecting components 21 through the end hooks 801 at both ends. 1 is hooked on the connecting plate 2102. After the rotating sleeve 803 is rotated, the screw 802 is inserted into the connecting tube 804 through the threaded connection between the rotating sleeve 803 and the screw 802, thereby realizing that the two end hooks 801 are separated from each other, and vice versa, the two end hooks 801 are close to each other. Under the connection of the two tensioning units cross-distributed up and down, the two herringbone frames 2 are tightened in parallel.

[0056] Working principle: After the upper connecting assembly 7 and the side clamp head 602 are connected to the herringbone frame 2 and the connecting beam 6 respectively, the herringbone frame 2 is slidably connected to the two ends of the connecting beam 6, and then the lower clamp seat 312 is pressed downward and the upper clamp seat 706 is pushed upward to place the support locking assembly 3 between the herringbone frame 2 and the connecting beam 6, and then the lower clamp seat 312 and the upper clamp seat 706 are released, and under the action of the second spring 310 and the sixth spring 708, the lower clamp seat 312 and the upper clamp seat 706 clamp the seat tube 303 at the two ends of the support locking assembly 3;

[0057] After the assembled A-frame 2 and connecting beam 6 are placed side by side, they are connected through the side connecting rod 5, and then the lower clamping seat 312 is pulled up to make the lower beam 4 pass through each connecting beam 6. After the lower clamping seat 312 is released, the second spring 310 drives the lower clamping seat 312 to move downward, so that the lower end of the lower clamping seat 312 extends into the connecting beam 6 to limit the connecting beam 6. Then, the adjacent connecting components 21 are cross-distributed and connected through the tensioning unit. After the end hook 801 corresponding to the tensioning unit hooks the third connecting hole of the connecting plate 2102, the rotating sleeve 803 is rotated to make the screw rod 802 extend into the connecting tube 804, thereby parallel tightening the A-frame 2;

[0058] After the support column with an annular groove at the upper end is fixed to the bottom surface on the side of the support column with the annular groove, the pipeline of the inflation equipment is connected to the inflation head 301, and then the herringbone frame 2 and the connecting beam 6 connected by the side connecting rod 5 and the connecting beam 6 are lifted, so that the first connecting hole of the small diameter part of the side connecting rod 5 to be connected to the top rod 6025 corresponds to the second connecting hole on the connecting shell, and after the insertion head 601 is aligned with the support column, the herringbone frame 2 and the connecting beam 6 connected by the side connecting rod 5 and the connecting beam 6 are slowly lowered, and the support column is opened. During the extension of the support column, the support rod 6021 is pushed to move upward, and then the support rod 6021 supports the limiting column 6027 to overcome the resistance of the lower pressure ring 6029 and the upper pressure ring 6028 to move upward. At this time, the resistance of the supporting limiting column 6027 to the wedge block 6026 is reduced, and then the third spring 6024 pushes the push rod 6025 to move toward the side connecting rod 5, and then the small diameter part of the push rod 6025 extends from the second connecting hole into the first connecting hole of the side connecting rod 5, so that the movement of the side connecting rod 5 is restricted;

[0059] Then, the upper beam 1 is lifted and placed on the A-frame 2 at a position corresponding to the upper connecting assembly 7. After the upper beam 1 is lowered, the upper locking rod 701 extends into the fourth connecting hole of the upper beam 1. As the upper beam 1 is lowered, the upper beam 1 presses the upper locking rod 701 downward, thereby pressing the connecting seat 702 to move downward. After the side locking rod 703 falls with the connecting seat 702 to the position where it meets the limiting plate, it is blocked. Under the push of the fourth spring 704, the side locking rod 703 extends into the fifth connecting hole through the third connecting hole. Under the elasticity of the sixth spring 708, the upper clamping seat 706 extends into the connecting port of the upper beam 1, and then the upper beam 1 and the upper connecting assembly 7 are locked together through the upper locking rod 701, the side locking rod 703, and the upper clamping seat 706.

[0060] Finally, the spiral extension airbag 305 is inflated by the inflation device, and the transition plate 306 is driven to move to the side away from the inflation head 301 during the inflation process, and then the transition plate 306 pushes the concrete slurry bag 315 to overcome the force of the first spring 304 to make the top plate 307 move to the side away from the spiral extension airbag 305. After the concrete slurry bag 315 hits the blade 308, the external structure is cut, and then the internal concrete enters the seat tube 303. The transition plate 306 pushes the connecting rod 309 to make the hook plate 316 pass through the channel 313 to reach the guide port 314. As the spiral extension airbag 305 drives the transition plate 306 to rotate, The connecting rod 309 drives the hook plate 316 to rotate to a position where it can extend through the guide opening 314, and then reaches the space corresponding to the second spring 310 and the sixth spring 708, and with further rotation, the fixing frame 707 and the connecting beam 6 are hooked on the side wall on the upper side of the cavity 311, thereby realizing the connection between the support locking assembly 3 and the upper connecting assembly 7 and the connection between the support locking assembly 3 and the connecting beam 6. Under the action of the gravity of the upper beam 1, the support column is further extended into the insertion head 601, so that the support rod 6021 pushes the limit column 6027 to move upward, so that the small diameter portion of the push rod 6025 will be further pushed into the first connecting hole by the third spring 6024.

[0061] The middle support column is clamped in the annular groove by the clamping assembly at the connection shell, thereby limiting the separation of the support column and the connection beam 6.

[0062] Embodiment 2:

[0063] The difference between this embodiment and the first embodiment is that the two clamping components are composed of an arc-shaped spring piece and a fixing rod made of spring steel. The fixing rod is fixedly connected to the space at the lower part of the connecting shell and above the insertion head 601. One end of the arc-shaped spring piece is fixed to the fixing rod, and the other end is close to each other above the insertion head 601. After the support column with an annular groove at the upper end is inserted into the insertion head 601, the upper end of the support column first stretches the arc-shaped spring piece, and then the arc-shaped spring piece is elastically reset and clamped in the annular groove.
