Description

Technical Field

[0001] The present invention belongs to the technical field of beam bottom support adjustment and fixing devices, and particularly relates to a combined beam and slab support frame. Background Art

[0002] When pouring the beam bottom, it is necessary to assemble the beam bottom formwork and the side formwork to form the pouring area of the beam bottom, and then install support rods or support seats at the position of the beam bottom to support the beam bottom. The existing support rods or support seats are usually fixedly connected to the beam bottom, and the height cannot be flexibly adjusted, which cannot meet the beam bottom support requirements of different heights. At the same time, when it is necessary to remove the beam bottom formwork and the side formwork after the beam bottom pouring is completed, since the traditional support rods or support seats are fixedly connected to the beam bottom, it is necessary to cancel the connecting bolts at the beam bottom one by one during disassembly, which is very time-consuming and laborious. And due to the large weight of the beam bottom, the traditional support structure is only supported by support rods, and its stability is insufficient, which is likely to bring potential safety hazards. Summary of the Invention

[0003] The purpose of the present invention is to provide a combined beam and slab support frame, which can support the beam and slab structure to meet different height requirements, and at the same time can be conveniently removed after the beam and slab structure is poured to reserve an early demolition space at the beam bottom, realizing the convenient and efficient early demolition of the beam bottom side formwork and the support structure.

[0004] The present invention is realized through the following technical solutions:

[0005] A combined beam and slab support frame includes a central lifting support rod and side lifting support rods arranged on the left and right sides of the central lifting support rod. A support keel is arranged at the top of the central lifting support rod. The left and right ends of the support keel are respectively connected to the side lifting support rods on the left and right sides. A beam bottom locking member is arranged at the central position at the top of the support keel. Lifting beam bottom fixing members with linear lifting are arranged on the left and right sides of the beam bottom locking member at the top of the support keel; a sliding beam bottom support member with linear sliding is arranged at the top of the side lifting support rods.

[0006] A support keel is arranged at the top of the central lifting support rod. The support keel is used to support the beam bottom in the beam and slab structure. The beam bottom formwork is directly placed on the top of the support keel, and the beam bottom formwork is locked and positioned by the beam bottom locking member at the central position at the top of the support keel. At the same time, the left and right sides of the beam bottom formwork are respectively placed on the lifting beam bottom fixing members on the left and right sides at the top of the support keel. The installation height of the beam bottom formwork on the support keel can be adjusted by the lifting of the lifting beam bottom fixing members. At the same time, the installation height of the support keel can be directly adjusted by the central lifting support rod. Furthermore, through the lifting cooperation of the central lifting support rod and the lifting beam bottom fixing members, the installation height of the beam bottom formwork can be flexibly adjusted in multiple sections.

[0007] On the left and right sides of the central lifting support rod, there are side lifting support rods. At the top of the side lifting support rods, there are sliding beam bottom support members for supporting the top panel. The square columns or bottom beams at the bottom of the top panel are directly placed on the top of the sliding beam bottom support members. By sliding the sliding beam bottom support members in the left-right direction, the installation position of the top panel in the left-right direction is adjusted, making the splicing of the top panels closer. At the same time, by lifting the side lifting support rods, the installation height of the sliding beam bottom support members is adjusted, and then the installation height of the top panel is adjusted.

[0008] After the beam-slab structure of the top panel is poured and completed, it is necessary to remove the beam bottom formwork. At this time, the lifting beam bottom fixing member descends, and thus an early demolition space is reserved between the support keel and the beam bottom. Workers can efficiently and conveniently demolish the beam bottom formwork through the early demolition space, thereby greatly improving the demolition efficiency of the beam bottom formwork and the support structure.

[0009] To better implement the present invention, further, the lifting beam bottom fixing member includes a lower early demolition support member and an upper early demolition support member arranged on the top of the lower early demolition support member, and the installation height of the upper early demolition support member on the top of the lower early demolition support member is adjustable.

[0011] To better implement the present invention, further, the lower early demolition support member and the upper early demolition support member are connected by a beam bottom lifting member; the beam bottom lifting member includes an adjusting sleeve, an adjusting screw, and an adjusting nut. The adjusting sleeve is arranged on the front and rear sides of the lower early demolition support member. The adjusting screw is threadedly installed vertically inside the adjusting sleeve. An adjusting nut that is rotatably connected to the top of the adjusting sleeve is sleeved on the adjusting screw, and the top of the adjusting screw is rotatably connected to the bottom of the upper early demolition support member.

[0012] To better implement the present invention, further, at least one fixing groove is symmetrically and linearly arranged on the front and rear sides of the center of the top of the support keel, and a beam bottom locking member is clamped in the fixing groove; telescopic inclined support devices are respectively arranged between the left and right sides and the left and right sides of the central lifting support rod at the bottom of the support keel.

[0013] To better implement the present invention, further, the telescopic inclined support device includes a first inclined support sleeve, a second inclined support sleeve, and an inclined support screw. The first inclined support sleeve and the second inclined support sleeve are respectively threadedly connected to both ends of the inclined support screw. The other end of the first inclined support sleeve is hinged to the side surface of the central lifting support rod, and the other end of the second inclined support sleeve is hinged to the bottom of the support keel.

[0014] To better implement the present invention, further, the sliding beam bottom support member includes a floor formwork support seat provided at the top of the side lifting support rod, a strip-shaped belt lifting seat provided on the top of the floor formwork support seat, and a strip-shaped belt support seat slidably arranged in the left-right direction on the top of the strip-shaped belt lifting seat. At least one U-shaped limit card is slidably arranged in the left-right direction on the front and rear sides of the floor formwork support seat, and at least one positioning card is provided on the front and rear sides of the top of the strip-shaped belt support seat.

[0015] To better implement the present invention, further, the floor formwork support seat includes two floor formwork support units arranged in the front-rear direction and spliced together. Semi-cylindrical tubes are correspondingly arranged on the splicing surfaces of the floor formwork support units, and after the splicing surfaces of the two floor formwork support units are spliced, the semi-cylindrical tubes on the two floor formwork support units are spliced to form a cylindrical tube for the side lifting support rod to pass through; connection holes are also correspondingly arranged on the splicing surfaces of the two floor formwork support units, and connection bolts are installed in the connection holes.

[0016] To better implement the present invention, further, the floor formwork support unit includes a vertical section and a horizontal section provided at the top of the vertical section. A semi-cylindrical tube is arranged in the middle of the vertical section, and a kidney-shaped installation groove is arranged in the left-right direction on the side of the horizontal section away from the vertical section. A U-shaped limit card is slidably installed in the kidney-shaped installation groove through a locking member.

[0017] To better implement the present invention, further, a kidney-shaped installation groove is arranged in the left-right direction on the top of the strip-shaped belt lifting seat, and a connection bolt slidably connected to the kidney-shaped installation groove is provided at the bottom of the strip-shaped belt support seat.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] (1) In the present invention, a central lifting support rod is directly arranged at the bottom of the supporting keel. The central lifting support rod can drive the supporting keel to flexibly adjust the supporting height, so as to meet the support for beam bottoms of different heights. At the same time, lifting beam bottom fixing parts are respectively arranged on the left and right sides at the top of the supporting keel. Through the lifting of the lifting beam bottom fixing parts themselves, the supporting height of the beam bottom on the top of the supporting keel is adjusted, so as to realize the flexible and convenient adjustment of the supporting height of the beam bottom, and solve the problem that the height of the traditional fixedly connected support parts cannot be adjusted.

[0020] (2) In the present invention, by arranging the lifting beam bottom fixing parts, when the lifting beam bottom fixing parts rise, they can effectively support and fix the beam bottom. After the beam bottom is poured, by lowering the lifting beam bottom fixing parts, an early demolition space is reserved between the beam bottom and the supporting keel. Through the early demolition space, the side formwork of the beam bottom and the supporting mechanism can be efficiently and conveniently demolished, thus greatly improving the early demolition efficiency.

[0021] (3) In the present invention, a strip-shaped belt lifting seat and a floor slab formwork supporting seat are sequentially sleeved on the side lifting support rod from top to bottom. At the same time, a strip-shaped belt supporting seat is slidably installed on the top of the strip-shaped belt lifting seat. According to the actual support requirements, the floor slab formwork supporting seat and the strip-shaped belt lifting seat can be driven by the side lifting support rod to rise and fall, and the actual installation height at the top of the strip-shaped belt supporting seat and the strip-shaped belt lifting seat can be adjusted, so as to flexibly adjust the final supporting height and supporting position. At the same time, by the sliding of the strip-shaped belt supporting seat along the left and right directions on the top of the strip-shaped belt lifting seat, the installation position of the strip-shaped belt supporting seat is adjusted, so as to realize the adjustment of the installation position of the top panel in the left and right directions.

[0022] (4) In the present invention, the floor slab formwork is stably supported by the floor slab formwork supporting seat. At the same time, U-shaped limit cards are arranged on the front and rear sides of the floor slab formwork supporting seat to support and limit the square column at the bottom of the top panel, so as to effectively avoid the displacement of the top panel and ensure the supporting stability of the beam and slab structure.

Detailed implementation mode

[0037] Embodiment 1:

[0038] A beam - slab combined support frame of this embodiment is as shown in Figure 1As shown in the figure, it includes a central lifting support rod 1 and side lifting support rods 2 arranged on the left and right sides of the central lifting support rod 1. A support keel 3 is provided at the top of the central lifting support rod 1. The left and right ends of the support keel 3 are respectively connected to the side lifting support rods 2 on the left and right sides. A beam bottom locking member 5 is provided at the central position of the top of the support keel 3. Lifting beam bottom fixing members 4 with linear lifting are provided on the left and right sides of the beam bottom locking member 5 at the top of the support keel 3. A sliding beam bottom support member 6 with linear sliding is provided at the top of the side lifting support rod 2.

[0039] The central position at the bottom of the support keel 3 is threadedly connected to the lifting screw rod at the top of the central lifting support rod 1 through a connecting sleeve. By rotating the lifting screw rod in the central lifting support rod 1, the support keel 3 is lifted and lowered to adjust the installation height of the support keel 3. The left and right ends of the support keel 3 are respectively connected to the rod segments of the side lifting support rods 2 on the left and right sides of the central lifting support rod 1 through hoop clamps, thus forming an integral support frame body, effectively improving the stability of the support structure. The sliding beam bottom support member 6 is threadedly installed at the top of the side lifting support rod 2 through a lifting screw rod. The sliding beam bottom support member 6 can move in the left-right direction at the top of the side lifting support rod 2, thereby adjusting the support position of the sliding beam bottom support member 6 in the left-right direction.

[0040] The support keel 3 is used to support the bottom of the beam in the beam-slab structure. The beam bottom formwork is directly placed on the top of the support keel 3, and the square column or border at the bottom of the beam bottom formwork is locked and positioned through the beam bottom locking member 5 at the central position of the top of the support keel 3. At the same time, the left and right sides of the beam bottom formwork are directly placed on the tops of the left and right lifting beam bottom fixing members 4. By the self-lifting of the lifting beam bottom fixing members 4, the installation height of the beam bottom formwork on the top of the support keel 3 is adjusted. Cooperating with the lifting adjustment of the support keel 3 by the central lifting support rod 1, the installation height of the beam bottom formwork can be adjusted with multiple large strokes, and the installation height of the beam bottom formwork can be conveniently and flexibly adjusted according to the actual construction conditions.

[0041] The sliding beam bottom support members 6 on the left and right sides are used to support the top panel in the beam-slab structure. The square column or border at the bottom of the top panel is placed on the top of the sliding beam bottom support member 6. By the movement of the sliding beam bottom support member 6 in the left-right direction, the top panel is driven to be finely adjusted in the left-right direction, making the splicing between adjacent top panels closer. At the same time, by directly lifting the side lifting support rod 2, the height of the sliding beam bottom support member 6 is adjusted, thereby realizing flexible adjustment of the installation height of the top panel. The installation height and the left-right installation position of the top panel can be conveniently and flexibly adjusted according to the actual construction situation.

[0042] After the beam-slab structure is poured and completed, the side lifting support rod 2 is adjusted to drive the sliding beam bottom support member 6 to descend, and the central lifting support rod 1 and the lifting beam bottom fixing member 4 are adjusted to drive the support keel 3 to descend, so that enough early removal space is reserved between the support frame and the beam-slab structure. Through the early removal space, the staff can conveniently and efficiently remove the beam bottom formwork and the top formwork quickly, and then the support frame can be removed conveniently. Through the above structural settings, not only is the height and the left and right installation positions flexible and adjustable when the beam-slab structure is erected, but also enough early removal space can be reserved after the beam-slab is poured to facilitate the rapid early removal of the beam bottom formwork, the top formwork, etc., thus greatly improving the construction efficiency.

[0043] Embodiment 2:

[0044] This embodiment is further optimized on the basis of the above Embodiment 1, as Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 shown, the lifting beam bottom fixing member 4 includes a lower early removal support member 41 and an upper early removal support member 42 arranged on the top of the lower early removal support member 41, and the installation height of the upper early removal support member 42 on the top of the lower early removal support member 41 is adjustable.

[0045] The lower early removal support member 41 is directly installed on the top of the support keel 3, and the upper early removal support member 42 is installed on the top of the lower early removal support member 41 in a vertically movable manner. The top of the upper early removal support member 42 is a support surface for supporting and positioning the beam bottom formwork. By adjusting the installation height of the upper early removal support member 42 on the top of the lower early removal support member 41, the installation height of the beam bottom formwork on the top of the support keel 3 can be flexibly adjusted.

[0046] Other parts of this embodiment are the same as those of the above Embodiment 1, so they will not be described again.

[0047] Embodiment 3:

[0048] This embodiment is further optimized on the basis of the above Embodiment 1 or 2, as Figure 5 and Figure 6 shown, the top of the lower early removal support member 41 is provided with a lower inclined surface, the bottom of the upper early removal support member 42 is provided with an upper inclined surface that is slidably matched with the lower inclined surface, a limiting portion 44 is arranged at the high end of the lower inclined surface, and an anti-loss installation member 45 is arranged at one end of the upper early removal support member 42 close to the limiting portion 44.

[0049] The bottom of the lower early dismantling support member 41 is a connecting plane, and the lower early dismantling support member 41 is directly placed on the top of the supporting keel 3 through the connecting plane at the bottom, and then the lower early dismantling support member 41 is fixedly installed on the top of the supporting keel 3 by a locking screw or a locking clamp, and the top of the lower early dismantling support member 41 is an inclined mounting surface. The top of the upper early dismantling support member 42 is a supporting plane, and the bottom of the beam is directly supported by the supporting plane. The bottom of the upper early dismantling support member 42 is a matching inclined surface set corresponding to the inclined mounting surface. Through the sliding cooperation between the matching inclined surface and the inclined mounting surface, the upper early dismantling support member 42 is realized to slide along the inclined mounting surface at the top of the lower early dismantling support member 41, and then the installation height of the upper early dismantling support member 42 at the top of the lower early dismantling support member 41 is adjusted to adapt to different beam bottom support requirements.

[0050] The limiting portion 44 is provided at the top of the inclined mounting surface to prevent the upper early dismantling support member 42 from sliding out and falling off from the top of the inclined mounting surface. The bottom of the beam is directly supported by the supporting plane at the top of the upper early dismantling support member 42, and then the bottom of the beam can be cast. After the bottom of the beam is cast, the end of the lower early dismantling support member 41 away from the limiting portion 44 is knocked by external force, so that the lower early dismantling support member 41 gradually slides out from the bottom of the upper early dismantling support member 42, so that the upper early dismantling support member 42 is no longer supported and falls, and a 2cm-3cm early dismantling space is left between the bottom of the beam and the supporting keel 3, and the bottom template of the beam can be quickly and conveniently disassembled through the early dismantling space.

[0051] Furthermore, a sliding groove is provided on the inclined mounting surface, and the sliding groove is connected with the bottom end of the inclined mounting surface; a sliding block slidably connected with the sliding groove is provided at the bottom of the upper early disassembly support member 42.

[0052] When the upper early disassembly support member 42 slides along the inclined mounting surface, the sliding block is synchronously driven to slide along the sliding groove, and the sliding of the upper early disassembly support member 42 is guided by the sliding cooperation between the sliding block and the sliding groove, so as to prevent the upper early disassembly support member 42 from being skewed or stuck. At the same time, the sliding groove is connected with the bottom end of the inclined mounting surface, so that when the lower early disassembly support member 41 is subsequently knocked, the sliding block can be directly disengaged from the through end of the sliding groove.

[0053] Furthermore, a lower connection hole is provided on the lower early disassembly support member 41, and an upper connection hole is provided on the upper early disassembly support member 42 corresponding to the lower connection hole. After the sliding adjustment of the upper early disassembly support member 42 is completed, a locking bolt can be inserted between the aligned upper connection hole and the lower connection hole, thereby locking the upper early disassembly support member 42 at the installation position at the top of the lower early disassembly support member 41.

[0054] Furthermore, connecting ears are symmetrically arranged on both sides of the bottom of the lower early disassembly support member 41, and connecting threaded holes are coaxially arranged on the connecting ears on both sides, and fastening connecting bolts are threadedly installed in the connecting threaded holes.

[0055] After the lower early-demountable support member 41 is placed on the top of the support keel 3, the connecting lugs on both sides of the bottom of the lower early-demountable support member 41 are located on both sides of the support keel 3, and mounting threaded holes are provided on both sides of the support keel 3 corresponding to the connecting threaded holes on the connecting lugs. By screwing and fastening connecting bolts in the aligned connecting threaded holes and mounting threaded holes, the convenient installation of the lower early-demountable support member 41 on the top of the support keel 3 is realized.

[0056] Further, a lower force application hole is provided at one end of the lower early-demountable support member 41 close to the limiting portion 44; an upper force application hole is provided at one end of the upper early-demountable support member 42 far from the limiting portion 44.

[0057] After the pouring at the bottom of the beam is completed and it is necessary to disassemble the lower early-demountable support member 41 and the upper early-demountable support member 42, it is not convenient to knock the lower early-demountable support member 41 with conventional tools such as hammers. At this time, the force application pins can be inserted into the lower force application hole and the upper force application hole, and then the force application pin in the lower force application hole and the force application pin in the upper force application hole are pulled in the direction away from each other, so that the lower early-demountable support member 41 and the upper early-demountable support member 42 can be disassembled conveniently and labor-savingly.

[0058] Further, the anti-loss mounting member 45 includes an L-shaped connecting block and a connecting column. A connecting column is provided at the bottom of the vertical end of the L-shaped connecting block. The bottom of the connecting column is connected to the upper early-demountable support member 42, and an anti-loss rope hole is provided on the horizontal end of the L-shaped connecting block.

[0059] A plugging hole is provided at the top of the upper early-demountable support member 42, and the connecting column is directly plugged and installed in the plugging hole. The L-shaped connecting block limits the side formwork at the bottom of the beam. At the same time, in order to prevent the L-shaped connecting block from falling off and being lost during the subsequent early disassembly process, an anti-loss rope hole is provided on the horizontal end of the L-shaped connecting block. By threading an anti-loss rope through the anti-loss rope hole on the horizontal end of the L-shaped connecting block and the anti-loss rope hole on the upper early-demountable support member 42 for connection, the falling off and loss of the L-shaped connecting block are effectively avoided.

[0060] Further, the inclination angle of the inclined mounting surface is 15° - 45°.

[0061] Other parts of this embodiment are the same as those of the above-mentioned Embodiment 1 or 2, so they will not be described in detail.

[0062] Embodiment 4:

[0063] This embodiment is further optimized on the basis of any one of the above-mentioned Embodiments 1 - 3, such as Figure 7 and Figure 8As shown, the lower early-disassembly support member 41 and the upper early-disassembly support member 42 are connected by a beam bottom lifting member 43; the beam bottom lifting member 43 includes an adjusting sleeve 431, an adjusting screw 432, and an adjusting nut 433. The adjusting sleeve 431 is arranged on the front and rear sides of the lower early-disassembly support member 41. The adjusting screw 432 is threadedly installed inside the adjusting sleeve 431 in the vertical direction. An adjusting nut 433 that is rotatably connected to the top of the adjusting sleeve 431 is sleeved on the adjusting screw 432. The top of the adjusting screw 432 is rotatably connected to the bottom of the upper early-disassembly support member 42.

[0064] The bottom of the lower early-disassembly support member 41 is an installation plane, and the installation plane is directly placed on the supporting keel 3. At this time, the connecting lugs on both sides of the bottom of the lower early-disassembly support member 41 are respectively located on both sides of the supporting keel 3. By screwing in the tightening bolts on the connecting lugs on both sides, the tightening bolts tightly hold the supporting keel 3 left and right, thereby realizing the fixed installation of the lower early-disassembly support member 41 on the top of the supporting keel 3.

[0065] The upper early-disassembly support member 42 is arranged on the top of the lower early-disassembly support member 41. The beam bottom lifting member 43 can drive the upper early-disassembly support member 42 to lift vertically on the top of the lower early-disassembly support member 41. The top of the upper early-disassembly support member 42 is a supporting plane, and the supporting plane is directly in contact with the beam bottom formwork, which is used to effectively support the beam bottom formwork. At the same time, for the beam bottom construction conditions with different height requirements, the installation height of the upper early-disassembly support member 42 is adjusted through the beam bottom lifting member 43, so as to meet the support for beam bottom formworks with different heights. At the same time, the limiting part 44 arranged at one end of the top of the lower early-disassembly support member 41 is in contact with the beam bottom side formwork, thereby effectively limiting the beam bottom side formwork.

[0066] After the beam bottom is poured, the beam bottom lifting member 43 drives the upper early-disassembly support member 42 to descend, so that the upper early-disassembly support member 42 is separated from the beam bottom formwork and an early-disassembly space is left. Through the early-disassembly space, the beam bottom formwork and the beam side formwork can be conveniently and early disassembled.

[0067] Further, the adjusting sleeve 431 is provided with a threaded hole, and the adjusting screw 432 is threadedly installed inside the adjusting sleeve 431. By rotating the adjusting nut 433, the adjusting screw 432 is driven to lift vertically, and then the upper early-disassembly support member 42 is driven to lift vertically. When the adjusting nut 433 is no longer rotated, due to the self-locking of the threaded connection structure between the adjusting screw 432 and the adjusting sleeve 431, the relative position between the upper early-disassembly support member 42 and the lower early-disassembly support member 41 is fixed.

[0068] Further, a clamping ring groove is provided at the top of the adjusting sleeve 431, and an annular flange that is rotatably clamped with the clamping ring groove is provided at the bottom of the adjusting nut 433. The annular flange extends into the clamping ring groove. The outer ring surface of the annular flange is in rotational fit with the inner ring surface of the clamping ring groove. The end faces on the upper and lower sides of the annular flange are respectively in fit with the upper side end face and the lower side end face of the clamping ring groove to achieve axial limit, so that the adjusting nut 433 can rotate on the top of the adjusting sleeve 431 but cannot move axially.

[0069] Further, T-shaped stepped grooves are respectively provided on both sides of the bottom of the upper early-demolition support member 42, and a T-shaped connecting block that is rotatably clamped with the T-shaped stepped grooves is provided at the top of the adjusting screw rod 432. The outer ring surface of the T-shaped connecting block is in rotational fit connection with the inner ring surface of the T-shaped stepped groove. The end faces on the upper and lower sides of the T-shaped connecting block are respectively in fit with the upper and lower side end faces of the T-shaped stepped groove for limit, so that the adjusting screw rod 432 can drive the upper early-demolition support member 42 to move up and down in the vertical direction while not driving the upper early-demolition support member 42 to rotate.

[0070] Further, the bottom end of the adjusting screw rod 432 extends downward to the outside of the adjusting sleeve 431 and is sleeved with a limit sleeve. When the adjusting screw rod 432 extends upward to the limit position, at this time, the top of the limit sleeve contacts the bottom of the adjusting sleeve 431 for limit, so that the adjusting screw rod 432 cannot continue to move upward, thereby preventing the adjusting screw rod 432 from disengaging from the adjusting sleeve 431.

[0071] Further, threaded holes are correspondingly provided on the connecting lugs on both sides of the bottom of the lower early-demolition support member 41, and fastening bolts are screwed and installed in the threaded holes. By rotating the fastening bolts, the fastening bolts can then press against both sides of the supporting keel 3, thereby realizing the convenient fixation of the lower early-demolition support member 41 on the top of the supporting keel 3. At the same time, the installation positions of the lower early-demolition support member 41 on the supporting keel 3 can also be limited by the connecting lugs on both sides.

[0072] Other parts of this embodiment are the same as any one of the above-mentioned Embodiments 1-3, so they will not be described in detail.

[0073] Embodiment 5:

[0074] On the basis of any one of the above-mentioned Embodiments 1-4, this embodiment is further optimized. As Figures 2 - 4 shown, at least one fixing groove is symmetrically and linearly provided on the front and rear sides of the center of the top of the supporting keel 3, and a beam bottom locking member 5 is clamped in the fixing groove; telescopic inclined support devices 7 are respectively provided between the left and right sides of the bottom of the supporting keel 3 and the left and right sides of the central lifting support rod 1.

[0075] The beam bottom locking member 5 includes a locking lug installed inside the fixed groove. A locking threaded hole is provided at the top of the locking lug, and a locking bolt is installed with internal threads in the locking threaded hole. The bottom beam of the strip-shaped support belt is placed between the locking lugs on both sides, and then by tightening the locking bolts, the two sides of the locking bolts press against both sides of the bottom beam of the strip-shaped support belt, thereby achieving the fixation of the bottom beam.

[0076] Further, the telescopic inclined support device 7 includes a first inclined support sleeve 71, a second inclined support sleeve 72, and an inclined support screw 73. The first inclined support sleeve 71 and the second inclined support sleeve 72 are respectively threadedly connected to both ends of the inclined support screw 73. The other end of the first inclined support sleeve 71 is hinged to the side surface of the central lifting support rod 1, and the other end of the second inclined support sleeve 72 is hinged to the bottom of the support keel 3.

[0077] By relatively rotating the first inclined support sleeve 71 and the inclined support screw 73, the length of the inclined support screw 73 extending into the first inclined support sleeve 71 is adjusted; similarly, by relatively rotating the second inclined support sleeve 72 and the inclined support screw 73, the length of the inclined support screw 73 extending into the second inclined support sleeve 72 is adjusted, thereby achieving the adjustment of the length of the entire telescopic inclined support device 7.

[0078] Further, in order to rotate the inclined support screw 73 conveniently and labor-savingly, force-applying handles are provided on both sides of the inclined support screw 73. By holding the force-applying handles, the inclined support screw 73 can be rotated labor-savingly.

[0079] Other parts of this embodiment are the same as any one of the above-mentioned Embodiments 1-4, so they will not be described in detail.

[0080] Embodiment 6:

[0081] This embodiment is further optimized on the basis of any one of the above-mentioned Embodiments 1-5, as Figure 4 shown. The central lifting support rod 1 includes a lifting sleeve 11, a lifting screw 12, and a lifting nut 13. The lifting screw 12 is installed with internal threads inside the lifting sleeve 11. The top end of the lifting screw 12 extends outside the lifting sleeve 11 and is threadedly sleeved with a lifting nut 13. The side surface of the lifting nut 13 is hinged to the other end of the first inclined support sleeve 71.

[0082] By rotating the lifting nut 13, the lifting screw 12 is driven to rotate, thereby adjusting the installation length of the lifting screw 12 in the lifting sleeve 11 and achieving the adjustment of the installation height of the lifting screw 12. The top of the lifting screw 12 is connected to the threaded sleeve at the bottom of the support keel 3, thereby driving the support keel 3 to lift and lower synchronously.

[0083] Furthermore, a semi-hoop that engages with each other is provided at the top of the lifting nut 13, and an ear is provided on the side surface of the semi-hoop and is hinged to the other end of the first inclined support sleeve 71.

[0084] Furthermore, the support keel 3 includes a central keel 31 and side keels 32 disposed on the left and right sides of the central keel 31. The bottom of the central keel 31 is connected to the lifting end of the central lifting support rod 1, and lifting beam bottom fixing members 4 are provided on the left and right sides at the top of the central keel 31; the bottom of the side keel 32 is hinged to one end of the telescopic inclined support device 7. The side keels 32 are spliced on the left and right sides of the central keel 31 and are connected by a connecting shaft. A hoop is provided at one end of the side keel 32 away from the central keel 31, and is connected to the side lifting support rod 2 through the hoop to form an integral support frame group.

[0085] Other parts of this embodiment are the same as any one of the above-mentioned Embodiments 1-5, and thus will not be described in detail.

[0086] Embodiment 7:

[0087] This embodiment is further optimized on the basis of any one of the above-mentioned Embodiments 1-6, as Figures 9 - 12 shown, the sliding beam bottom support member 6 includes a floor formwork support seat 61 provided at the top of the side lifting support rod 2, a strip-shaped belt lifting seat 62 provided at the top of the floor formwork support seat 61, and a strip-shaped belt support seat 63 slidably disposed along the left-right direction on the top of the strip-shaped belt lifting seat 62. At least one U-shaped limit card 64 is slidably disposed along the left-right direction on the front and rear sides of the floor formwork support seat 61, and at least one positioning card is provided on the front and rear sides at the top of the strip-shaped belt support seat 63.

[0088] The side lifting support rod 2 drives the floor formwork support seat 61 to lift in the vertical direction, thereby adjusting the installation height of the strip-shaped belt lifting seat 62 and the strip-shaped belt support seat 63. The bottom of the strip-shaped belt lifting seat 62 is connected to the top of the lifting screw rod of the side lifting support rod 2 through a threaded sleeve, and the top of the strip-shaped belt lifting seat 62 is slidably connected to the bottom of the strip-shaped belt support seat 63 in the left-right direction. By sliding the strip-shaped belt support seat 63, the installation position of the strip-shaped belt support seat 63 on the top of the strip-shaped belt lifting seat 62 can be adjusted, and then the position of the strip-shaped belt support seat 63 can be fixed by a locking pin or a locking screw. The top of the strip-shaped belt support seat 63 is a strip-shaped belt support surface, which is used to support and limit the bottom of the top panel.

[0089] The floor formwork support base 61 is located below the strip lifting base 62. The floor formwork support base 61 rises and falls along with the side lifting support rod 2. The top of the floor formwork support base 61 is the floor formwork support surface. By using the floor formwork support surface to support the square column at the bottom of the top panel, and at the same time, in order to prevent the square column from moving in the left-right direction and causing the floor formwork to shift, U-shaped limit cards 64 are slidably arranged in the left-right direction at the corresponding positions on the front and rear sides of the end of the floor formwork support base 61. By moving the U-shaped limit cards 64 left and right, the actual installation positions of the U-shaped limit cards 64 on the front and rear sides of the end of the floor formwork support base 61 can be adjusted, and then the positions of the U-shaped limit cards 64 can be fixed by locking pins or locking screws. The top opening of the U-shaped limit card 64 is used to insert the square column. The opening width of the U-shaped limit card 64 is equal to or slightly larger than the width of the square column. By directly placing the square column inside the opening of the U-shaped limit card 64, the U-shaped limit card 64 can effectively limit the square column and prevent the square column from shifting in the left-right direction, thereby ensuring the installation stability of the top panel.

[0090] Positioning cards protruding upward are arranged on the front and rear sides of the top of the strip support base 63. When the top panel is placed on the top of the strip support base 63, the side frames at the bottom of the top panel are just located between the positioning cards on the front and rear sides. Thus, the top panel is limited in the front-rear direction by the positioning cards on the front and rear sides, preventing the top panel from shifting violently in the front-rear direction.

[0091] Other parts of this embodiment are the same as any one of the above-mentioned Embodiments 1-6, so they will not be described in detail.

[0092] Embodiment 8:

[0093] This embodiment is further optimized on the basis of any one of the above-mentioned Embodiments 1-7, such as Figure 10 and Figure 11 As shown, the floor formwork support base 61 includes two floor formwork support units 611 arranged in the front-rear direction and spliced together. Semi-cylindrical barrels 612 are correspondingly arranged on the splicing surfaces of the floor formwork support units 611. After the splicing surfaces of the two floor formwork support units 611 are spliced together, the semi-cylindrical barrels 612 on the two floor formwork support units 611 are spliced to form a cylindrical barrel for the side lifting support rod 2 to pass through. Connecting holes are also correspondingly arranged on the splicing surfaces of the two floor formwork support units 611, and connecting bolts are installed in the connecting holes.

[0094] The splicing surfaces of two floor formwork support units 611 are spliced together. At this time, the semi-cylindrical tubes 612 on the splicing surfaces of the two floor formwork support units 611 are correspondingly spliced to form a cylindrical tube for the side lifting support rod 2 to pass through. At the same time, a number of connecting holes are correspondingly arranged on the splicing surfaces of the two floor formwork support units 611. By inserting connecting bolts into the corresponding connecting holes and tightening them with nuts, the convenient splicing of the two floor formwork support units 611 is realized. When it is necessary to demolish the overall floor formwork support base 61 in the later stage, only the connecting bolts need to be loosened, and then the two floor formwork support units 611 can be quickly separated and disassembled.

[0095] Further, the floor formwork support unit 611 includes a vertical section and a horizontal section provided at the top of the vertical section. A semi-cylindrical tube 612 is provided in the middle of the vertical section. A waist-shaped mounting groove is arranged in the left-right direction on the side of the horizontal section away from the vertical section. A U-shaped limit card 64 is slidably mounted in the waist-shaped mounting groove through a locking member. A locking bolt is installed between the waist-shaped mounting grooves on the horizontal sections of the front and rear floor formwork support units 611. A through hole for the locking bolt to pass through is provided on the U-shaped limit card 64. When the position of the U-shaped limit card 64 is adjusted, the locking nut sleeved on the locking bolt can be tightened, and then the side of the U-shaped limit card 64 facing the waist-shaped mounting groove can be tightened to fix the U-shaped limit card 64.

[0096] Other parts of this embodiment are the same as any one of the above-mentioned Embodiments 1-7, so they will not be described in detail.

[0097] Embodiment 9:

[0098] On the basis of any one of the above-mentioned Embodiments 1-8, this embodiment is further optimized. A waist-shaped mounting groove is arranged in the left-right direction at the top of the strip-shaped belt lifting seat 62. A connecting bolt slidably connected to the waist-shaped mounting groove is provided at the bottom of the strip-shaped belt support seat 63.

[0099] The connecting bolt passes downward through the waist-shaped mounting groove and is sleeved with a connecting nut. By sliding the connecting bolt along the waist-shaped mounting groove, the mounting position of the strip-shaped belt support seat 63 on the top of the strip-shaped belt lifting seat 62 is adjusted, and then the connecting nut can be tightened so that the connecting nut tightens the bottom end face of the waist-shaped mounting groove, thereby realizing the position fixation of the strip-shaped belt support seat 63.

[0100] Other parts of this embodiment are the same as any one of the above-mentioned Embodiments 1-8, so they will not be described in detail.
