Description

Technical Field

[0001] The invention belongs to the technical field of beam-slab support devices, and particularly relates to a beam-slab support frame structure and system which are convenient for adjusting early removal. Background Art

[0002] The beam-slab structure is mainly composed of structures such as beam walls, beams, and top panels. The beam is an important load-bearing structure in a building. When pouring the beam structure, usually the beam wall formwork is used to construct the shape of the beam, and then concrete is poured into the beam wall formwork to form the beam structure. In order to ensure the stability and safety of the beam pouring, support components such as support rods and support columns are required to support the beam wall formwork. The traditional support rods or support columns perform point support on the bottom of the beam wall formwork and are connected by connecting bolts, etc. Not only is the support not firm enough, but also the connection structure is complex, which limits the removal of the beam wall formwork after the beam body is poured, reducing the removal efficiency of the beam wall formwork. At the same time, once the traditional support structure is fixed, it is difficult to adjust the support height of the beam wall in real time, and it is difficult to meet the support requirements of beam wall formworks with different height requirements. At the same time, due to the relatively fixed connection structure between the traditional support structure and the beam wall formwork, it is also difficult to finely adjust the installation position of the beam wall formwork on the support member.

[0003] At the same time, in the traditional beam-slab combined structure, once the beam wall formwork and the top panel are fixed by existing support structures such as support rods, their relative positions are difficult to adjust. At the same time, the existing support structures and the beam wall formwork, top panel mostly adopt fixed connection structures with cumbersome construction, and there is no adaptive and convenient support for whether there is a bottom beam at the bottom of the plate surface, resulting in the existing support system being difficult to flexibly adjust, inconvenient to disassemble and assemble, and its support stability is difficult to meet the requirements of safe fixed support when the beam-slab structure is large in volume and heavy in weight. Summary of the Invention

[0004] The purpose of the invention is to provide a beam-slab support frame structure and system which are convenient for adjusting early removal, can realize combined adjustable support for the beam wall formwork and the top panel, realize convenient adjustable combination of the beam-slab structure, and can ensure the stability of the overall support structure.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0017] (1) By detachably installing side support beams at both ends of the central support beam, the present invention can extend the support range, achieve surface support for the bottom of the beam wall formwork, and make the support effect more stable; at the same time, by replacing side support beams of different lengths, it can adapt to the compatible support of beam wall formworks with different width specifications.

[0018] (2) By movably arranging the beam wall formwork on the top of the central support beam and / or side support beam, the support position of the beam wall formwork can be conveniently adjusted when the beam wall formwork is not fixed; at the same time, by movably arranging a beam bottom bidirectional fixing connector on the top of the central support beam and / or side support beam, the bottom of the beam wall formwork is fixed in both the width and length directions through the beam bottom bidirectional fixing connector, thereby achieving stable positioning of the beam wall formwork.

[0019] (3) By arranging a beam and slab lifting and separating support member on the top of the central support beam and / or side support beam, the top of the beam wall formwork is supported by the beam and slab lifting and separating support member. By jacking up the beam and slab lifting and separating support member, the support height of the beam wall formwork is adjusted. At the same time, when the beam wall formwork is removed later, a early removal space is reserved by lowering the beam and slab lifting and separating support member, thereby enabling the beam wall formwork to be removed conveniently and quickly, and improving the early removal efficiency.

[0020] (4) By setting up a top panel lifting adjustment rod assembly to drive the top beam and slab bottom support and the top beam and slab support base to perform vertical lifting, thereby adjusting the support height of the top panel. At the same time, in view of whether a bottom beam structure such as a square column or a square beam is provided at the bottom of the top panel, top beam and slab support members and / or bottom beam limit members are fixedly or detachably arranged at both ends of the top beam and slab bottom support. The top panel is directly supported by the top beam and slab support members, and the bottom beam is limited and supported by the bottom beam limit members; at the same time, a top beam and slab fixing member is linearly slidably arranged on the top of the top beam and slab support base. By adjusting the installation position of the top beam and slab fixing member, the support position of the top panel is adjusted, thereby achieving efficient and stable support for the top panel.

[0021] (5) By fixedly connecting the beam wall formwork lifting adjustment rod assembly, the top panel lifting adjustment rod assembly, the central support beam, the side support beam, and the beam and slab combined support head to form a beam and slab support frame structure, convenient and adjustable stable support for the beam and slab combined structure is achieved.

Specific embodiments

[0036] Embodiment 1:

[0037] A beam and slab support frame structure for facilitating early removal and adjustment in this embodiment, asFigures 1-4 As shown in the figure, it includes a beam-wall formwork lifting and adjusting rod assembly and a top panel lifting and adjusting rod assembly. A central support beam 41 is provided at the top of the beam-wall formwork lifting and adjusting rod assembly. Detachable side support beams 43 are respectively installed at the left and right ends of the central support beam 41. A top panel lifting and adjusting rod assembly is detachably installed at one end of the side support beam 43 away from the central support beam 41. At the top of the central support beam 41 and / or the side support beam 43, there are provided a beam bottom two-way fixing connecting piece 45 for two-way positioning of the bottom of the beam-wall formwork and a beam-wall lifting and separating support piece 46 for supporting and jacking up the beam-wall formwork. At the top of the top panel lifting and adjusting rod assembly, there is provided a beam and slab combined support head 3 with adjustable direction. At the top of the beam and slab combined support head 3, there are provided a beam limiting part for limiting the bottom beam of the top panel and / or a beam and slab support part for directly supporting the slab surface of the top panel.

[0038] Adjust the height of the central support beam 41 through the beam-wall formwork lifting and adjusting rod assembly, and support the bottom of the beam-wall formwork through the central support beam 41. Before the beam-wall formwork is positioned and fixed, it can be moved and finely adjusted along the width direction and the length direction of the central support beam 41. At the same time, for an extra-wide beam-wall formwork, side support beams 43 are installed on both sides of the central support beam 41 to extend the support range of the central support beam 41, so as to be compatible with supporting beam-wall formworks of different specifications and models. After the position adjustment of the beam-wall formwork is completed, the beam bottom two-way fixing connecting piece set on the top of the central support beam 41 and / or the side support beam 43 can be used to tightly fix the bottom of the beam-wall formwork along the width direction and the length direction of the central support beam 41 respectively. The specific installation position of the beam bottom two-way fixing connecting piece 45 on the top of the central support beam 41 and / or the side support beam 43 depends on the width specification and the positioning position of the beam-wall formwork. At the same time, a beam-wall lifting and separating support piece 46 is also provided on the top of the central support beam 41 and / or the side support beam 43, and the beam-wall lifting and separating support piece 46 can lift itself. When the beam-wall lifting and separating support piece 46 is in the lowered state, the jacking surface at its top is flush with the top support surface of the central support beam 41, and the bottom of the beam-wall formwork is placed on the top of the central support beam 41 and the beam-wall lifting and separating support piece 46. When it is necessary to adjust the height of the beam-wall formwork, lift the beam-wall lifting and separating support piece 46, and then jack up the beam-wall formwork upward to realize fine adjustment of the installation height of the beam-wall formwork on the top of the central support beam 41.

[0039] One end of the side support beam 43 close to the central support beam 41 is detachably connected to the end of the central support beam 41. At the end of the side support beam 43 far from the central support beam 41, a top panel lifting and adjusting rod assembly is provided. At the top of the top panel lifting and adjusting rod assembly, a combined beam and plate support head 3 for supporting the top panel is provided. For the top panel with a bottom beam, the beam limiting part of the combined beam and plate support head 3 is used to support and limit the bottom beam at the bottom of the top panel. For the top panel without a bottom beam, the beam and plate support part of the combined beam and plate support head 3 directly supports the bottom of the top panel.

[0040] Embodiment 2:

[0041] On the basis of Embodiment 1, this embodiment is further optimized. As Figure 1 shown, at the end of the side support beam 43 far from the central support beam 41, a top panel lifting and adjusting rod connecting piece 44 for connecting and limiting the top panel lifting and adjusting rod assembly is provided. At the bottom position of the outer side of the top panel lifting and adjusting rod assembly corresponding to the end of the side support beam 43 far from the central support beam 41, a main beam keel support fastener 1 is sleeved. The main beam keel support fastener 1 is used to support the bottom end face of the end of the side support beam 43 far from the central support beam 41, and at the same time, the main beam keel support fastener 1 clamps and limits the top panel lifting and adjusting rod connecting piece 44.

[0042] The top panel lifting and adjusting rod connecting piece 44 is detachably connected to the top panel lifting and adjusting rod assembly, so that the central support beam 41, the side support beam 43, and the top panel lifting and adjusting rod assembly form an integral support structure to improve the support stability of the beam wall formwork and the top panel. At the same time, by setting the main beam keel support fastener 1 to clamp and limit the top panel lifting and adjusting rod connecting piece 44, the loosening of the top panel lifting and adjusting rod connecting piece 44 is avoided, and the stability of the connection between the side support beam 43 and the top panel lifting and adjusting rod assembly is further ensured.

[0043] Other parts of this embodiment are the same as those of the above Embodiment 1, so they will not be described in detail.

[0044] Embodiment 3:

[0045] On the basis of the above Embodiment 1 or 2, this embodiment is further optimized. As Figures 10-12 shown, the main beam keel support fastener 1 includes a positioning hoop sleeved on the outside of the top panel lifting and adjusting rod assembly. At the top of the positioning hoop, a beam end support part 13 directly supporting the bottom of the end of the side support beam 43 far from the central support beam 41 is provided. On one side of the beam end support part 13, a limit disk buckle 14 is provided. At the top of the limit disk buckle 14, a limit bayonet 15 for clamping and limiting the top panel lifting and adjusting rod connecting piece 44 is provided.

[0046] The positioning hoop includes a first half-hoop 11 and a second half-hoop 12 that are joined together to form an integral hoop structure. On one side of the top of the first half-hoop 11 and the top of the second half-hoop 12, support plates are symmetrically arranged to form a support portion 13. On one side of the top of the cylindrical structure formed by the first half-hoop 11 and the second half-hoop 12, a limit disc buckle 14 is provided. At the top of the limit disc buckle 14, a limit bayonet 15 is provided corresponding to the position of the top panel lifting adjustment rod connector 44.

[0047] Semicircular bayonets are correspondingly arranged on the first half-hoop 11 and the second half-hoop 12. By correspondingly fitting the semicircular bayonet on the first half-hoop 11 with the semicircular bayonet on the second half-hoop 12, an integral hoop structure of a cylindrical structure can be formed. At one end of the semicircular bayonet of the first half-hoop 11 and one end of the semicircular bayonet of the second half-hoop 12, hinge ears with hinge holes are correspondingly arranged. By inserting a hinge shaft into the aligned hinge holes, the rotational hinge between one end of the first half-hoop 11 and the second half-hoop 12 can be realized. At the other end of the semicircular bayonet of the first half-hoop 11 and the other end of the semicircular bayonet of the second half-hoop 12, connection ears with connection holes are correspondingly arranged. By inserting a connection bolt or a connection pin into the aligned connection holes, the fitting of the first half-hoop 11 and the second half-hoop 12 can be realized.

[0048] The cylindrical structure formed by the first half-hoop 11 and the second half-hoop 12 is directly sleeved outside the top panel lifting adjustment rod assembly. At this time, the end of the side support beam 43 can be directly placed on the top of the support plate, and the bottom end face of the side support beam 43 is supported by the support plate. At the same time, the top panel lifting adjustment rod connector 44 at the end of the side support beam 43 extends towards the limit disc buckle 14 and enters the limit bayonet 15 at the top of the limit disc buckle 14. Through the engagement of the limit bayonet 15 and the top panel lifting adjustment rod connector 44, the limit of the top panel lifting adjustment rod connector 44 and the top panel lifting adjustment rod assembly is realized.

[0049] Further, the limit bayonet 15 is a square bayonet or an arc bayonet.

[0050] The limit disc buckle 14 includes a support portion 141 and a limit portion 142. The support portion 141 is arranged on one side of the cylindrical structure, and the limit portion 142 is arranged on the top of the support portion 141. A limit bayonet 15 is provided on the limit portion 142 corresponding to the top opening of the cylindrical structure; the limit portion 142 is detachably arranged on the top of the support portion 141. For top panel lifting adjustment rod connectors 44 of different size specifications, only need to disassemble the limit portion 142 on the top of the support portion 141 and replace it with a limit portion 142 with a limit bayonet 15 of the corresponding size specification.

[0051] Further, one end of the bottom surface of the limiting part 142 is rotationally hinged to one side of the top of the cylindrical structure, and the other end of the bottom surface of the limiting part 142 is lapped on the top end surface of the supporting part 141.

[0052] An articulated hole is provided at one end of the bottom surface of the limiting part 142 close to the cylindrical structure corresponding to the top of the articulated shaft on one side of the cylindrical structure. The limiting part 142 is rotationally hinged to the top of the articulated shaft through the articulated hole, so that the limiting part 142 can be rotationally adjusted at a certain angle with the articulated shaft as the rotation axis, and then the orientation of the limiting bayonet 15 on the limiting part 142 is adjusted, so that the limiting bayonet 15 engages with the end of the main support beam. At the same time, the top end surface of the supporting part 141 supports the other end of the bottom surface of the limiting part 142 away from the cylindrical structure, ensuring the stability of the limiting part 142.

[0053] The size specification and shape of the limiting bayonet 15 are both set corresponding to the size specification and shape of the end of the main support beam.

[0054] A positioning lug is provided at one end of the support plate away from the top opening of the cylindrical structure, and a positioning hole is provided on the positioning lug.

[0055] The end of the side support beam 43 is placed between the two side positioning lugs. The end of the side support beam 43 is limited by the positioning lugs to further prevent the side support beam 43 from moving. After the end of the side support beam 43 is placed on the top of the support plate, after the top panel lifting adjustment rod connecting piece 44 at the end of the side support beam 43 is engaged and limited by the limiting bayonet 15 on the limiting disc buckle 14, a positioning bolt or a positioning pin can be inserted into the positioning hole on the positioning lug, and the side of the side support beam 43 is tightened by the positioning bolt or the positioning pin, so as to further limit the side support beam 43.

[0056] Other parts of this embodiment are the same as those of the above Embodiment 1 or 2, so they will not be described in detail.

[0057] Embodiment 4:

[0058] On the basis of any one of the above Embodiments 1-3, this embodiment is further optimized. As Figure 4 shown, an end slot for the top panel lifting adjustment rod assembly to pass through is provided at one end of the side support beam 43 away from the central support beam 41. The top panel lifting adjustment rod connecting piece 44 includes a support rod half hoop and / or a support rod clamping block arranged inside the end slot, and a space for holding and limiting the top panel lifting adjustment rod assembly is formed between adjacent support rod half hoops and / or support rod clamping blocks.

[0059] On both sides of the end groove, bayonets or clamping grooves are correspondingly arranged, and a support rod semi-hoop and / or a support rod clamping block are arranged between the corresponding bayonets or clamping grooves. For example, two adjacent support rod semi-hoops are arranged to form an integral hoop structure, two support rod clamping blocks are arranged to clamp both sides of the top panel lifting adjustment rod assembly, one support rod semi-hoop and one support rod clamping block are arranged, one side of the top panel lifting adjustment rod assembly is clamped by the support rod clamping block, and the other side of the top panel lifting adjustment rod assembly is held by the support rod semi-hoop.

[0060] 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.

[0061] Embodiment 5:

[0062] On the basis of any one of the above-mentioned Embodiments 1-4, this embodiment is further optimized. For example, Figures 7-9 As shown, the beam-slab combined support head 3 includes a top beam-slab bottom support 31 arranged on the top of the top panel lifting adjustment rod assembly. A top beam-slab support base 33 is arranged on the top of the top beam-slab bottom support 31. A top beam-slab fixing member 34 is linearly slidably arranged on the top of the top beam-slab support base 33. At both ends of the top beam-slab bottom support 31, a bottom beam limiting member 35 and / or a top beam-slab support member 32 are respectively arranged. The space between the bottom beam limiting member 35 and the top beam-slab support base 33 forms a beam limiting part for limiting the bottom beam of the top panel, and the top end face of the top beam-slab support member 32 forms a beam-slab support part for directly supporting the plate surface of the top panel.

[0063] When the top panel lifting adjustment rod assembly is vertically lifted or lowered, it will synchronously drive the top beam-slab bottom support 31 and the top beam-slab support base 33 to be vertically lifted or lowered, thereby adjusting the support height of the top panel. At the same time, a top beam-slab fixing member 34 is linearly slidably arranged on the top of the top beam-slab support base 33. The bottom of the top panel is supported and positioned by the top beam-slab fixing member 34, and at the same time, the installation position of the top beam-slab fixing member 34 on the top of the top beam-slab support base 33 is adjusted by linear sliding, thereby adjusting the support position of the top beam-slab fixing member 34 on the bottom surface of the top panel, and avoiding applying a support force at the weak part of the top panel.

[0064] At the same time, a bottom beam limiting member 35 or a top beam-slab support member 32 is fixedly or detachably arranged at both ends of the top beam-slab bottom support 31. According to the specific support situation, a bottom beam limiting member 35 or a top beam-slab support member 32 is arranged at the end of the top beam-slab bottom support 31.

The area between the bottom beam limiting member 35 and one side of the top beam and slab support base 33 forms a beam limiting portion, and the bottom beam is arranged in the beam limiting portion. The bottom beam is supported by the top end face of the top beam and slab support 31, and at the same time, the bottom beam is limited by the beam limiting portion.

[0066] If no bottom beam structure such as a square column or a square beam is provided at the bottom of the top panel, a top beam and slab support member 32 is directly fixedly or detachably provided at the end of the top beam and slab support 31 corresponding to the bottom surface of the top panel, and the top panel is directly supported by the beam and slab support portion at the top of the top beam and slab support member 32.

[0069] On the basis of any one of the above embodiments 1-4, this embodiment is further optimized. For example, Figure 7 As shown, the bottom beam limiting member 35 includes a bottom beam limiting plate fixedly or detachably provided at the end of the top beam and slab support 31. The area between the bottom beam limiting plate and the side surface of the top beam and slab support base 33 forms a beam limiting portion for limiting the bottom beam at the bottom of the top panel.

[0070] Bottom beam limiting plates are provided at both ends of the top beam and slab support 31. One bottom beam limiting plate is detachably connected to the U-shaped groove on one end of the top beam and slab support 31, and the other bottom beam limiting plate is fixedly welded or fixedly clamped to the other end of the top beam and slab support 31.

[0071] Furthermore, adjustment holes are provided on the bottom beam limiting member 35, and the installation position of the top beam and slab support 31 can be conveniently adjusted through the adjustment holes.

[0072] Other parts of this embodiment are the same as any one of the above embodiments 1-4, so they will not be described in detail.

[0074] On the basis of any one of the above embodiments 1-4, this embodiment is further optimized. For example, Figure 7 As shown, the top beam and slab support member 32 includes a top beam and slab support seat. The bottom of the top beam and slab support seat is fixedly or detachably connected to the top end surface of the end of the top beam and slab support 31, and the top end surface of the top beam and slab support seat extends above the top beam and slab support 31 and forms a beam and slab support portion for directly supporting the plate surface of the top panel.

[0075] A beam bottom limiting plate is provided at one end of the top beam and slab bottom support 31, and a beam and slab support seat is provided at the other end of the top beam and slab bottom support 31. The bottom of the beam and slab support seat is detachably connected to the U-shaped groove at the other end of the top beam and slab bottom support 31, or is directly fixedly welded or fixedly clamped to the other end of the top beam and slab bottom support 31. The bottom of the beam and slab support seat is placed on the top end surface of the top beam and slab bottom support 31, and the top end surface of the beam and slab support seat constitutes a beam and slab support part for directly supporting the top panel.

[0076] Further, the top of the top beam and slab support member 32 is a hollow structure, and an adjustment hole is provided at the bottom of the top beam and slab support member 32.

[0077] A linear chute is provided at the top of the top beam and slab support base 33, and the bottom of the top beam and slab fixing member 34 is slidably connected to the linear chute. A positioning groove or positioning opening is provided at the top of the top beam and slab fixing member 34.

[0078] Further, a connecting bolt slidably connected to the linear chute is provided at the bottom of the top beam and slab fixing member 34, and the bottom end of the connecting bolt passes downward through the linear chute and is threadedly sleeved with a locking nut. After the linear adjustment of the top beam and slab fixing member 34 is completed, the top beam and slab fixing member 34 can be conveniently fixed at the installation position on the top of the top beam and slab support base 33 by tightening the locking nut.

[0079] Positioning card plates are provided on both sides of the top of the top beam and slab fixing member 34, and a positioning groove or positioning opening is formed between the positioning card plates on both sides. A top-tightening bolt or top-tightening pin is threadedly provided on the positioning card plate.

[0080] The top panel is directly placed on the top end surface of the top beam and slab fixing member 34 and is located between the positioning card plates on both sides, thereby realizing the bottom support and limitation of the top panel.

[0081] 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.

[0082] Embodiment 8:

[0083] This embodiment is further optimized on the basis of any one of the above-mentioned Embodiments 1-4, such as Figure 5 As shown, the beam bottom bidirectional fixing connector 45 includes fixed mounting frames 453 provided on both sides along the width direction at the top of the central support beam 41. A first-direction top-tightening member 451 for top-tightening the beam wall formwork along the width direction of the central support beam 41 is provided at the top of the fixed mounting frame 453; a second-direction top-tightening member 452 for top-tightening the beam wall formwork along the length direction of the central support beam 41 is provided at the top of the first-direction top-tightening member 451.

[0084] On both sides of the central support beam 41 and / or the side support beam 43 symmetrically and slidably arranged along the width direction, there are fixed mounting brackets 453. Connecting holes are correspondingly arranged between the bottoms of the fixed mounting brackets 453 on both sides. A fastening bolt is inserted between the connecting holes at the bottoms of the fixed mounting brackets 453 on both sides, and a fastening nut is threadedly sleeved at one end of the fastening bolt. When the fastening nut is not tightened, at this time, the fixed mounting brackets 453 on both sides can linearly slide along the central support beam 41 or the side support beam 43, thereby adjusting the position of the fixed mounting bracket 453. After the position adjustment of the fixed mounting bracket 453 is completed, the fastening nut can be optionally tightened so that the fastening nut presses and fixes the fixed mounting bracket 453. At this time, the fixed mounting bracket 453 cannot continue to slide to achieve positioning and fixing.

[0085] On the tops of the fixed mounting brackets 453 on both sides, there are first-direction pressing members 451 correspondingly arranged along the width direction of the central support beam 41. When the beam-wall formwork is placed on the top of the central support beam 41 or the side support beam 43, the bottom edge frame of the beam-wall formwork is just located between the first-direction pressing members 451 on both sides in the width direction. Then, the first-direction pressing members 451 on both sides approach each other until the bottom edge frame of the beam-wall formwork is pressed and fixed in the width direction, restricting the degree of freedom of the beam-wall formwork along the width direction of the central support beam 41.

[0086] On the top of at least one first-direction pressing member 451, a second-direction pressing member 452 is arranged along the length direction of the central support beam 41. By the second-direction pressing member 452 pressing the bottom of the beam-wall formwork along the length direction of the central support beam 41, the degree of freedom of the beam-wall formwork along the length direction of the central support beam 41 is further restricted.

[0087] Furthermore, the first-direction pressing member 451 includes a first-direction nut whose axis is arranged along the width direction of the central support beam 41, and a first-direction bolt is threadedly installed in the inner hole of the first-direction nut.

[0088] By screwing the first-direction bolt, the first-direction bolts arranged on both sides in the width direction of the central support beam 41 approach each other, thereby pressing and positioning the bottom of the beam-wall formwork located between the first-direction bolts on both sides.

[0089] Furthermore, the second-direction pressing member 452 includes a second-direction nut whose axis is arranged along the length direction of the central support beam 41 on the top of the first-direction pressing member 451, and a second-direction bolt is threadedly installed in the inner hole of the second-direction nut. By screwing the second-direction bolt, the second-direction bolt presses and positions the bottom frame of the beam-wall formwork along the length direction of the central support beam 41.

[0090] Other parts of this embodiment are the same as any one of the above Embodiments 1-4, so they will not be described in detail.

[0091] Example 9:

[0092] This embodiment is further optimized on the basis of any one of the above embodiments 1-4. As Figure 6 shown, the beam-wall lifting and separating support member 46 includes a beam-wall lifting base 461, a beam-wall separating jacking seat 462, and a beam-wall jacking screw 463. The beam-wall lifting base 461 is linearly slidably arranged on the top of the central support beam 41 and / or the side support beam 43. A beam-wall jacking screw 463 is rotationally arranged with threads on the beam-wall lifting base 461, and a beam-wall separating jacking seat 462 is arranged at the top of the beam-wall jacking screw 463.

[0093] The bottom end face of the beam-slab lifting base 461 is in sliding contact with the top end face of the central support beam 41 or the side support beam 43, so that the beam-slab lifting base 461 can slide along the length direction of the central support beam 41 or the side support beam 43, and then adjust the installation position of the beam-slab lifting base 461 to adapt to the support of beam-wall formworks with different width specifications. The bottom of the beam-slab lifting base 461 is respectively provided with lug ears corresponding to both sides in the width direction of the central support beam 41 or both sides in the width direction of the side support beam 43, and locking bolts are threadedly installed on the lug ears on both sides. After the position of the beam-slab lifting base 461 is adjusted, the locking bolts on the lug ears can be screwed, so that the ends of the locking bolts tighten both sides in the width direction of the central support beam 41 or both sides in the width direction of the side support beam 43, thereby realizing the positioning and fixing of the beam-slab lifting base 461.

[0094] A vertical threaded hole is provided on the beam-slab lifting base 461, and a jacking screw 463 is threadedly installed in the threaded hole. A beam-wall separating jacking seat 462 is arranged at the top of the jacking screw 463. A clamping groove is provided at the top of the beam-wall separating jacking seat 462 corresponding to the top end of the jacking screw 463, and the top end of the jacking screw 463 is rotationally clamped with the clamping groove. This enables the jacking screw 463 to drive the beam-wall separating jacking seat 462 to move up and down when rotating, but not drive the beam-wall separating jacking seat 462 to rotate.

[0095] The top end face of the beam-wall separating jacking seat 462 supports the bottom of the beam-wall formwork. By rotating the jacking screw 463, the beam-wall separating jacking seat 462 is driven to move up and down, and then the beam-wall formwork is driven to move up and down.

[0096] Furthermore, a linear adjustment sliding groove is provided on the beam-slab lifting base 461 and / or the beam-wall separating jacking seat 462.

[0097] Other parts of this embodiment are the same as any one of the above embodiments 1-4, so they will not be elaborated here.
