Description

Technical Field

[0001] The present invention relates to a basement roof beam structure and a construction method, belonging to the technical field of building construction. Background Art

[0002] During the construction process of the basement roof and beam structure, column, beam, and roof formwork are usually used together. First, the load-bearing columns are concreted, and then the beams and roofs are concreted. The pouring operation of conventional concrete load-bearing columns needs to use the layered method, that is, the main body needs to be poured in several times along the vertical direction and separate vibration operations are required. This slows down the efficiency of the pouring operation of the entire column body, thereby affecting the construction progress of the roof beam. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to provide a basement roof beam structure and a construction method, which solve the problem that in the prior art, the pouring operation of conventional concrete load-bearing columns needs to use the layered method, that is, the main body needs to be poured in several times along the vertical direction and separate vibration operations are required, which slows down the efficiency of the pouring operation of the entire column body.

[0004] The technical problem to be solved by the present invention is achieved by the following technical solutions: The basement roof beam structure includes a bottom plate, and further includes:

[0005] Column formwork, vertically arranged on the bottom plate and hollow inside to form a filling cavity.

[0006] Beam formwork, arranged between adjacent column formworks.

[0007] Side formwork, arranged at the end of the column formwork, and the side formwork is arranged in a horizontal surrounding manner.

[0008] Roof formwork, arranged on the side of the beam formwork away from the side formwork.

[0009] Communication holes are opened on the opposite sides of adjacent column formworks and on the side of the beam formwork away from the side formwork. An auxiliary device for communicating with the inside of the beam formwork and the column formwork is arranged on the communication holes.

[0010] Among them, the column formwork, beam formwork, side formwork, and roof formwork surround to form a pouring space with an opening facing away from the bottom plate side. Several steel reinforcement cages are arranged in the pouring space and filled with concrete mortar, and the auxiliary device is used for vibrating the concrete mortar.

[0011] By adopting the above technical solution, first install column formwork, beam formwork, roof formwork and side formwork on the bottom plate in sequence to form a space to be poured. Then place the steel reinforcement cage in the space to be poured, and then pour concrete mortar into the space to be poured. The auxiliary device can vibrate the concrete mortar inside the column formwork through the communication hole, and at the same time, conventional vibrating equipment can also be used to vibrate the concrete mortar inside the column formwork. At this time, during the process of pouring concrete, it is not necessary to pour and vibrate the concrete mortar inside the column formwork in two times. In this way, the pouring efficiency of the column formwork can be improved. At the same time, compared with the traditional method of vibrating above the column formwork, the concrete discharges bubbles more fully and is mixed more densely, which is beneficial to improving the pouring quality of the concrete mortar.

[0012] The present invention is further provided that: the auxiliary device includes:

[0013] A connecting flange is fixedly arranged on the outer side of the column formwork. The inside of the connecting flange is a hollow structure and penetrates through the connecting flange along the axial direction of the connecting flange. The hollow structure inside the connecting flange is communicated and aligned with the communication hole.

[0014] An elastic blocking block is inserted into the inside of the connecting flange and its end extends into the communication hole.

[0015] A vibrating assembly is detachably and fixedly arranged at the end of the connecting flange far from the column formwork. The vibrating assembly is used for directly vibrating the concrete mortar.

[0016] By adopting the above technical solution, the connecting flange is fixed to the column formwork, and at the same time, the communication hole is partially blocked by the elastic blocking block. At this time, the user can use a conventional vibrating rod or other rod-shaped objects to pass through the elastic blocking block and insert them into the concrete mortar in the filling cavity to vibrate and mix the concrete sufficiently to quickly discharge the bubbles. At this time, the elastic blocking block blocks the space of the communication hole to prevent the concrete from flowing out through the opening of the communication hole during the vibrating process and affecting the pouring quality.

[0017] The present invention is further provided that: the vibrating assembly includes:

[0018] A stirring steel bar, one end of which passes through the elastic blocking block and extends into the filling cavity, and the other end of the stirring steel bar extends to the side of the connecting flange far from the column formwork.

[0019] An intermediate flange is fixedly arranged at the end of the connecting flange far from the column formwork and the intermediate flange surrounds the outside of the stirring steel bar.

[0020] A rotating cylinder is rotatably arranged at the end of the intermediate flange far from the connecting flange and the end of the stirring steel bar extends into the inside of the rotating cylinder.

[0021] A clamping structure is arranged on the rotating cylinder for clamping the stirring steel bar.

[0022] A driving structure is arranged outside the rotating cylinder and is used to drive the rotating cylinder to rotate.

[0023] The present invention is further arranged as follows: The clamping structure includes:

[0024] Threaded rods are oppositely arranged in the radial direction of the rotating cylinder. One end of the threaded rod extends to the inner side of the rotating cylinder, and the threaded rod is rotatably connected to the rotating cylinder.

[0025] Clamping blocks are slidably arranged in the rotating cylinder along the radial direction of the rotating cylinder. One end of the clamping block can abut against the stirring steel bar, and the other end of the clamping block is threadedly connected to the end of the threaded rod.

[0026] The present invention is further arranged as follows: The driving structure includes:

[0027] An outer flange is sleeved outside the rotating cylinder. One end of the outer flange is detachably and fixedly connected to the middle flange. There is a gap between the outer flange and the rotating cylinder, and the end of the threaded rod extends into the gap.

[0028] A driving motor is fixed at one end of the outer flange away from the middle flange. An output end is arranged on the driving motor, and the output end extends into the outer flange and is fixedly connected to the rotating cylinder.

[0029] By adopting the above technical solution, by rotating the threaded rod, the two clamping blocks slide along the radial direction of the rotating cylinder to clamp or release the clamping of the stirring steel bar. And by only rotating a single threaded rod to adjust the position of one clamping block, the two clamping blocks can move the end of the stirring steel bar towards an eccentric position. At this time, the stirring steel bar is in an inclined state. Since the elastic blocking block has elasticity, it can deform following the inclined direction of the stirring steel bar. At this time, start the driving motor to drive the rotating cylinder to rotate, so as to drive the stirring steel bar to rotate through the threaded rod and the clamping block. Since the stirring steel bar is inclined at this time, the part of the stirring steel bar located in the filling cavity perturbs the concrete inside the filling cavity, which is beneficial to improving the exhaust and mixing of the concrete. Matching with the conventional vibrating rod used above the column formwork, it can discharge the gas in each part of the column formwork to the greatest extent, enabling the column formwork to be poured at one time and improving the pouring efficiency of the column formwork.

[0030] The present invention is further arranged as follows: After the column formwork is filled with concrete mortar to form a load-bearing structure, a number of bubble bricks are stacked at the adjacent column formworks provided with communication holes. One end of the stirring steel bar is located in the load-bearing structure and is fixedly connected to the load-bearing structure in an embedded manner, and the other end of the stirring steel bar extends to the stacked bubble bricks and is fixedly connected to the bubble bricks in an embedded manner. The number of stacked bubble bricks forms a retaining wall structure.

[0031] By adopting the above technical solution, after the concrete in the filling cavity is vibrated by using the stirring steel bar, the outer flange is disassembled from the middle flange, and then the threaded rod is rotated to release the clamping of the clamping block on the stirring steel bar. At this time, the end of the stirring steel bar is located in the concrete. When the concrete solidifies into a load-bearing structure, the connecting flange is then separated from the column formwork. At this time, the stirring steel bar and the elastic baffle block remain in the communication hole, and the stirring steel bar is fixedly connected with the load-bearing structure in an embedded manner. At this time, a number of bubble bricks are stacked between adjacent column formworks to form a retaining wall structure. The retaining wall structure is connected with the load-bearing structure through the stirring steel bar, which can directly improve the structural strength of the retaining wall structure, eliminate the need to set up construction column reinforcement bars to connect with the retaining wall structure, reduce the secondary pouring process, and is conducive to improving the overall construction efficiency.

[0032] Construction method for basement top beam structure, the construction method comprising:

[0033] S1: Fix the column formwork on the floor slab and form a filling cavity inside the column formwork;

[0034] S2: Fix the beam formwork on the side away from the floor slab between adjacent column formworks, so that both the beam formwork and the column formwork have an opening facing away from the floor slab;

[0035] S3: Surround and fix the side formwork at the end away from the floor slab of the beam formwork and the column formwork, and fix the top formwork between adjacent column formworks within the space surrounded by the side formwork, so that the column formwork, the beam formwork, the side formwork and the top formwork surround and form a space to be poured;

[0036] S4: Place a number of steel reinforcement cages into the space to be poured;

[0037] S5: Fix the auxiliary device on the column formwork and the beam formwork provided with communication holes;

[0038] S6: Fill the space to be poured with concrete mortar and start the auxiliary device to vibrate the concrete mortar;

[0039] S7: After the vibration is completed and waiting for the concrete mortar to dry, remove the column formwork, the beam formwork, the side formwork and the top formwork.

[0040] The beneficial effects of the present invention are: when pouring concrete, the auxiliary device can vibrate the concrete mortar inside the column formwork through the communication hole, and at the same time, conventional vibration equipment can also be used to vibrate the concrete mortar inside the column formwork. At this time, during the process of pouring concrete, there is no need to pour and vibrate the concrete mortar inside the column formwork in two times, which can improve the pouring efficiency of the column formwork. At the same time, compared with the traditional method of vibrating from above the column formwork, the concrete discharges bubbles more fully and is mixed more densely, which is conducive to improving the pouring quality of the concrete mortar.

Specific embodiments

[0046] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0047] Such as Figure 1As shown in the figure, the basement top slab beam structure includes a bottom slab, and further includes column formwork 10, a communication hole 11, beam formwork 12, side formwork 13 and top slab formwork 14. The column formwork 10 is vertically and fixedly arranged on the bottom slab and is hollow inside to form a filling cavity 16. The beam formwork 12 is arranged on the side away from the bottom slab between adjacent column formworks 10. The beam formwork 12 is arranged in a U shape with the opening facing away from the bottom slab. The two ends of the beam formwork 12 communicate with the filling cavity 16. The concrete mortar at the joint between the beam formwork 12 and the column formwork 10 cannot pass through. The communication hole 11 is opened on the opposite sides of adjacent column formworks 10 and on the side of the beam formwork 12 away from the side formwork 13. On the same side, several communication holes 11 are arranged vertically. An auxiliary device is detachably and fixedly arranged on the communication hole 11. The side formwork 13 is fixedly arranged at the end of the column formwork 10. The side formwork 13 is arranged in a horizontal circle and abuts against the beam formwork 12. The concrete mortar at the joints between the side formwork 13 and the column formwork 10 and the beam formwork 12 respectively cannot pass through. The top slab formwork 14 is arranged on the side of the beam formwork 12 away from the side formwork 13. The top slab formwork 14 blocks the side of the adjacent beam formwork 12 facing the bottom slab, so that the column formwork 10, the beam formwork 12, the side formwork 13 and the top slab formwork 14 surround to form a pouring space with the opening facing away from the bottom slab. A plurality of steel reinforcement cages 15 are arranged in the pouring space. The auxiliary device can be replaced with a traditional vibrating rod. The end of the traditional vibrating rod is directly inserted into the filling cavity 16 through the communication hole 11 to vibrate the concrete mortar at different positions.

[0048] As Figure 2-3 shown in the figure, the auxiliary device includes a connecting flange 20, an elastic sealing block 21 and a vibrating assembly. The connecting flange 20 is fixedly arranged on the outside of the column formwork 10. The fixing method usually uses bolt fasteners or pin fasteners for fixing. The inside of the connecting flange 20 is a hollow structure and penetrates the connecting flange 20 along the axial direction of the connecting flange 20. The hollow structure inside the connecting flange 20 communicates and aligns with the communication hole 11. The elastic sealing block 21 is inserted into the inside of the connecting flange 20 and the end extends into the communication hole 11. The friction between the elastic sealing block 21 and the communication hole 11 is greater than the friction between the elastic sealing block 21 and the connecting flange 20. When the connecting flange 20 is disassembled, the elastic sealing block 21 remains on the communication hole 11 under the action of friction, and the elastic sealing block 21 is removed synchronously with the column formwork 10. The vibrating assembly is detachably and fixedly arranged at one end of the connecting flange 20 away from the column formwork 10. The vibrating assembly is used for directly vibrating the concrete mortar.

[0049] As Figure 2-3As shown in the figure, the vibrating assembly includes a stirring steel bar 17, an intermediate flange 22, a rotating cylinder 24, a clamping structure, and a driving structure. One end of the stirring steel bar 17 extends through the elastic blocking block 21 into the filling cavity 16, and the other end of the stirring steel bar 17 extends to the side of the connecting flange 20 away from the column supporting formwork 10. The intermediate flange 22 is fixedly arranged at one end of the connecting flange 20 away from the column supporting formwork 10, and the intermediate flange 22 surrounds the outside of the stirring steel bar 17. The rotating cylinder 24 is rotatably arranged at one end of the intermediate flange 22 away from the connecting flange 20. The inside of the rotating cylinder 24 is hollow and communicates with the inside of the intermediate flange 22. The end of the stirring steel bar 17 extends into the inside of the rotating cylinder 24. The clamping structure is arranged on the rotating cylinder 24 for clamping the stirring steel bar 17, and the driving structure is arranged outside the rotating cylinder 24 for driving the rotating cylinder 24 to rotate. The clamping structure includes a clamping block 25 and a threaded rod 26. The threaded rods 26 are arranged oppositely in the radial direction of the rotating cylinder 24. One end of the threaded rod 26 extends into the inside of the rotating cylinder 24, and the threaded rod 26 is rotatably connected to the rotating cylinder 24. The clamping blocks 25 are arranged oppositely. The clamping blocks 25 are slidably arranged in the rotating cylinder 24 along the radial direction of the rotating cylinder 24. One end of the clamping block 25 facing the stirring steel bar 17 can abut against the stirring steel bar 17. The end of the threaded rod 26 is inserted into the clamping block 25 and is threadedly connected to the threaded rod 26. The driving structure includes an outer flange 23 and a driving motor 27. The outer flange 23 is sleeved outside the rotating cylinder 24. One end of the outer flange 23 is detachably and fixedly connected to the intermediate flange 22. There is a gap between the outer flange 23 and the rotating cylinder 24, and the end of the threaded rod 26 extends into the gap. The driving motor 27 is fixed at one end of the outer flange 23 away from the intermediate flange 22. The driving motor 27 is provided with an output end, and the output end extends into the inside of the outer flange 23 and is fixedly connected to the rotating cylinder 24.

[0050] As Figure 4 shown, after the column supporting formwork 10 is filled with concrete mortar, a load-bearing structure 29 is formed. A number of bubble bricks 28 are stacked at adjacent column supporting formworks 10 provided with communication holes 11. Concrete mortar is filled between adjacent bubble bricks 28. One end of the stirring steel bar 17 is located in the load-bearing structure 29 and is fixedly connected to the load-bearing structure 29 in an embedded manner. The other end of the stirring steel bar 17 extends to the stacked bubble bricks 28 and is fixedly connected to the stacked and dried bubble bricks 28 in an embedded manner. After a number of bubble bricks 28 are stacked, a retaining wall structure is formed.

[0051] First, install the column formwork 10, beam formwork 12, roof formwork 14, and side formwork 13 on the bottom plate in sequence to form a space to be concreted. Then, place the steel reinforcement cage 15 in the space to be concreted. After that, pour the concrete mortar into the space to be concreted. The auxiliary device can vibrate the concrete mortar inside the column formwork 10 through the communication hole 11, and at the same time, conventional vibrating equipment can also be used to vibrate the concrete mortar inside the column formwork 10. At this time, during the process of pouring concrete, there is no need to pour and vibrate the concrete mortar inside the column formwork 10 in two times. This can improve the pouring efficiency of the column formwork 10. At the same time, compared with the traditional method of vibrating above the column formwork 10, the concrete discharges bubbles more fully and is mixed more densely, which is beneficial to improving the pouring quality of the concrete mortar.

[0052] Fix the connecting flange 20 to the column formwork 10, and at the same time, use the elastic blocking block 21 to partially block the communication hole 11. At this time, the user can use a conventional vibrating rod or other rod-shaped objects to pass through the elastic blocking block 21 and insert them into the concrete mortar in the filling cavity 16 to vibrate and mix the concrete sufficiently to quickly discharge the bubbles. At this time, the elastic blocking block 21 blocks the space of the communication hole 11 to prevent the concrete from flowing out through the opening of the communication hole 11 during the vibration process and affecting the pouring quality.

[0053] By rotating the threaded rod 26, the two clamping blocks 25 slide radially along the rotating cylinder 24 to clamp or release the stirring steel bar 17. And by only rotating a single threaded rod 26 to adjust the position of one clamping block 25, the two clamping blocks 25 can move the end of the stirring steel bar 17 towards an eccentric position. At this time, the stirring steel bar 17 is in an inclined state. Since the elastic blocking block 21 is elastic, it can deform along with the inclination direction of the stirring steel bar 17. At this time, start the driving motor 27 to drive the rotating cylinder 24 to rotate, so as to drive the stirring steel bar 17 to rotate through the threaded rod 26 and the clamping blocks 25. Since the stirring steel bar 17 is inclined at this time, the part of the stirring steel bar 17 located in the filling cavity 16 disturbs the concrete inside the filling cavity 16, which is beneficial to improving the exhaust and mixing of the concrete. Combined with the conventional vibrating rod used above the column formwork 10, the gas in each part of the column formwork 10 can be discharged to the greatest extent, enabling the column formwork 10 to be poured at one time and improving the pouring efficiency of the column formwork 10.

[0054] After the concrete in the filling cavity 16 is vibrated by using the stirring steel bar 17, the outer flange 23 is disassembled from the middle flange 22, and then the clamping block 25 releases the clamping of the stirring steel bar 17 by rotating the threaded rod 26. At this time, the end of the stirring steel bar 17 is located in the concrete. When the concrete solidifies, it becomes the load-bearing structure 29. Then, the connecting flange 20 is separated from the column formwork 10. At this time, the stirring steel bar 17 and the elastic blocking block 21 remain in the communication hole 11, and the stirring steel bar 17 is fixedly connected with the load-bearing structure 29 in an embedded manner. Then, after the column formwork 10, the beam formwork 12, the side formwork 13 and the top plate formwork 14 are all removed, a number of bubble bricks 28 are stacked between adjacent column formworks 10 to form a retaining wall structure. The bubble bricks 28 in the retaining wall structure are bonded by concrete mortar to form a stable support. At the same time, the retaining wall structure is connected with the load-bearing structure 29 through the stirring steel bar 17, which can directly improve the structural strength of the retaining wall structure, eliminate the need to set up construction column steel bars to connect with the retaining wall structure, reduce the process of secondary pouring of the construction column, and is conducive to improving the overall construction efficiency.

[0055] The construction method of the basement top plate beam structure, the construction method includes:

[0056] S1: Fix the column formwork 10 on the bottom plate, and form a filling cavity 16 inside the column formwork 10. Adjacent column formworks 10 and between the column formwork 10 and the bottom plate can be fixed by woodworking nails or other fixing parts. The column formwork 10 can be provided with a multi-layer staggered structure at the joint to avoid gaps at the splicing of the column formwork 10;

[0057] S2: Fix the beam formwork 12 on the side away from the bottom plate between adjacent column formworks 10, so that both the beam formwork 12 and the column formwork 10 have the opening facing away from the bottom plate. The beam formwork 12 and the column formwork 10 can be fixed by woodworking nails or other fixing parts. The beam formwork 12 can be provided with a multi-layer staggered structure at the joint to avoid gaps at the splicing;

[0058] S3: Fix the side formwork 13 around the ends of the beam formwork 12 and the column formwork 10 away from the bottom plate, and fix the top plate formwork 14 between adjacent column formworks 10 in the space surrounded by the side formwork 13. The side formwork 13 and the top plate formwork 14 are respectively fixed to the column formwork 10 and the beam formwork 12 by woodworking nails or other fixing parts, so that the column formwork 10, the beam formwork 12, the side formwork 13 and the top plate formwork 14 surround to form a space to be poured;

[0059] S4: Place a number of steel cages 15 into the space to be poured;

[0060] S5: Fix the connecting flange 20 in the auxiliary device on the column formwork 10 and beam formwork 12 provided with the communication holes 11, align the inside of the connecting flange 20 with the communication holes 11, and then insert the elastic blocking block 21 into the communication holes 11 through the connecting flange 20 to block the communication holes 11, or use a vibrating rod to insert into the filling cavity 16 through the communication holes 11. At this time, the vibrating rod can partially block the communication holes 11 leaving only gaps for vibration;

[0061] S6: Fill the filling cavity 16 in the space to be poured with concrete mortar, and start the auxiliary device or a conventional vibrating rod to vibrate the concrete mortar. After the filling cavity 16 is filled with concrete mortar, use the mortar chasing method to fill the parts on the beam formwork 12 and roof formwork 14 with concrete mortar to complete the pouring operation of the roof and beam;

[0062] S7: After the vibration is completed, if the auxiliary device is used, retain the stirring steel bar 17 and the elastic blocking block 21 and remove the remaining structure of the auxiliary device from the column formwork 10. At this time, the elastic blocking block 21 blocks the communication holes 11. If a conventional vibrating rod is used, after pulling out the vibrating rod, use a baffle, flexible filler or other blocking structure to block the communication holes 11, and wait for the concrete mortar to dry. After waiting for the concrete mortar to dry, remove the column formwork 10, beam formwork 12, side formwork 13 and roof formwork 14;

[0063] S8: Stack the foam bricks 28 between adjacent column formworks 10, and fill the concrete mortar between the stacked foam bricks 28 to bond the adjacent foam bricks 28, and then form a retaining wall structure. The stirring steel bar 17 is located inside the retaining wall structure, thus completing the construction of the basement roof beam structure.

[0064] Among them, in step S6, when filling the filling cavity 16 with concrete mortar, the concrete mortar can be introduced into the filling cavity 16 through one of the communication holes 11 closest to the bottom plate, so that the concrete mortar slowly rises in the filling cavity 16 and overflows into the beam formwork 12 and roof formwork 14. This can further reduce the mixing of air in the concrete mortar during the pouring process, and at the same time can avoid quality defects such as honeycombing and pockmarks due to the reduction of mortar volume in the lower part, and at the same time reduce the construction duration of the subsequent vibration process, which is beneficial to improving the overall construction efficiency of the building.
