Technical Field
[0001] The present application relates to the technical field of building construction, and particularly to a demountable aluminum alloy bottom formwork truss floor slab formwork support system. Background Art
[0002] A truss floor slab, also known as a steel bar truss formwork, is a composite structure system. In this system, the main load-bearing steel bars in the floor slab are processed into steel bar trusses in a factory using special equipment, and then the steel bar trusses are welded to a steel plate as a whole. After pouring concrete, a steel bar truss concrete floor slab will be formed. This kind of floor slab can bear the service load during the service stage. Due to its economic, convenient, safe and reliable characteristics, the truss floor slab is widely used in modern buildings.
[0003] In the prior art, the formwork support system mainly includes a formwork, a roof support and a diagonal brace. During building construction, workers build the formwork on-site according to the design requirements; and support the top of the formwork through the roof support, and support the side of the formwork through the diagonal brace. Through the settings of the roof support and the diagonal brace, the formwork is supported and fixed, so as to facilitate subsequent concrete pouring.
[0004] However, in actual application of such a formwork support system, the formwork cannot be disassembled until the concrete is completely solidified and reaches the design strength, and then the roof support, the diagonal brace and the formwork can be disassembled in sequence. This means that the service life of the formwork is relatively long and the turnover efficiency is low, resulting in huge overall cost expenditures of the formwork in the construction of large buildings. Therefore, further improvement is needed. Summary of the Invention
[0005] In order to reduce the use turnover period of the formwork and improve the construction efficiency, the present application provides a demountable aluminum alloy bottom formwork truss floor slab formwork support system.
[0006] The demountable aluminum alloy bottom formwork truss floor slab formwork support system provided by the present application adopts the following technical solutions: A demountable aluminum alloy bottom formwork truss floor slab formwork support system includes a top formwork, a side formwork, a roof support member and a diagonal brace member. Among them, the top formwork has a roof support surface, the side formwork has a side support surface, and both the roof support surface and the side support surface include support bars and support plates. The roof support member is used to support the support bars of the roof support surface, and the diagonal brace member is used to support the support bars of the side support surface; a plurality of the support bars are arranged side by side, and adjacent two of the support bars are spaced apart to form a support area, and the support plate is arranged in the support area; a connecting member is provided between the support plate and the support bar, and the support plate is detachably installed on the support bar through the connecting member.
[0007] By adopting the above technical solution, the support plate is installed in the support area through the connecting piece. After the top formwork and the side formwork are erected and supported and fixed respectively by the top support piece and the inclined support piece, the steel bar truss and the steel plate are erected in the top formwork, and the steel bars are tied in the side formwork. Then, concrete is poured into the top formwork and the side formwork. When the concrete reaches the designed strength (the concrete is not completely solidified), the support plate can be detached through the connecting piece, while the top support piece and the inclined support piece are retained, greatly shortening the use turnover cycle of the support plate, enabling the support plate to be used in the next construction link more quickly, reducing the expenditure of the overall project cost, and improving the construction efficiency.
[0008] Optionally, a reinforcing convex edge is arranged on the plate surface of the support plate, and the reinforcing convex edge is annular around the edge of the plate surface of the support plate; reinforcing ribs are installed inside the reinforcing convex edge, and two ends of each reinforcing rib are respectively connected to two opposite inner side walls of the reinforcing convex edge, and the reinforcing ribs are arranged at intervals with the plate surface of the support plate to form an operation gap.
[0009] By adopting the above technical solution, the arrangement of the reinforcing convex edge and the reinforcing ribs improves the structural strength of the support plate and reduces the possibility of the support plate deforming. The reinforcing ribs are arranged at intervals with the plate surface of the support plate to form an operation gap. On the one hand, the reserved operation gap can facilitate the insertion of the worker's hand, thus facilitating the handling and transfer of the support plate; on the other hand, when the support plate can be removed, the operation gap can be used for the hook to extend in for hanging connection, so as to facilitate the detachment of the support plate.
[0010] Optionally, a first support seat is further included. The inclined support piece includes an inclined support sleeve, an inclined support rod and an inclined support head. There are two inclined support rods, and the two inclined support rods are respectively threadedly inserted at both ends of the inclined support sleeve, and the thread directions between the inclined support sleeve and the two inclined support rods are opposite; one end of one inclined support rod away from the inclined support sleeve is connected to the first support seat, and the other end of the other inclined support rod away from the inclined support sleeve is connected to the inclined support head, and the inclined support head is used for connecting the support strip of the side support surface.
[0011] By adopting the above technical solution, rotating the inclined support sleeve can force the two inclined support rods to approach or move away from each other to support the side support surface.
[0012] Optionally, the top support piece includes a top support sleeve, a top support rod and a top support head. One end of the top support rod is inserted into the top support sleeve, and the other end is connected to the top support head. The top support head is used for connecting the support strip of the top support surface; an adjusting head is rotatably installed at one end of the top support sleeve close to the top support rod, and the top support rod is threadedly inserted through the adjusting head.
[0013] By adopting the above technical solution, rotating the adjusting head enables the top support rod to lift to support the top support surface.
[0014] Optionally, there are two side molds, and both sides of the top mold are respectively lapped on the two side molds; the first support seats are correspondingly arranged on both side molds, and a second support seat is arranged between the first support seats corresponding to the two side molds. A first socket for inserting the top support sleeve is provided on the second support seat; the second support seat is provided with a docking assembly, and the second support seat is installed between the first support seats corresponding to the two side molds through the docking assembly.
[0015] By adopting the above technical solution, the second support seat is arranged between the first support seats corresponding to the two side molds through the docking assembly to connect the two first support seats in series. The reaction forces (from the reaction forces of the respective corresponding diagonal braces) received by the two first support seats can cancel each other out on the second support seat, achieving force balance and improving the stability of the overall structure.
[0016] Optionally, the docking assembly includes docking rods and opposing members. There are two docking rods, and the two docking rods are correspondingly arranged with the two first support seats. One end of each docking rod is connected to the second support seat, and the other end is connected to the corresponding first support seat. The second support seat is connected to the two first support seats respectively through the two docking rods; the opposing member is arranged on the second support seat, and the opposing member is used to force the two docking rods to move away from each other.
[0017] By adopting the above technical solution, the second support seat is connected to the two first support seats through the two docking rods, thereby "connecting in series" the two first support seats. The opposing member forces the two docking rods to move away from each other to tightly press the corresponding first support seats, enabling the two first support seats to be in force balance, and further improving the support effect on the side molds.
[0018] Optionally, an installation cavity is formed in the second support seat, and a communication groove communicating with the installation cavity is formed in the top wall of the second support seat; the opposing member includes a driving block and an opposing block. The driving block is slidably installed in the installation cavity, the first socket is threadedly penetrated through the communication groove, and one end of the first socket extends into the installation cavity and is rotatably connected to the driving block; there are two opposing blocks, and both opposing blocks are slidably installed in the installation cavity. The two opposing blocks are correspondingly arranged with the two docking rods. One end of each docking rod extends into the installation cavity and is connected to the corresponding opposing block; the driving block has a first pushing surface, and the opposing block has a second pushing surface for the first pushing surface to abut against. When the driving block moves downward, the two opposing blocks move away from each other.
[0019] By adopting the above technical solution, after the docking rod is connected to the corresponding first support seat, rotate the first socket to drive the driving block to move downward. The driving block can drive the two opposing blocks to move away from each other through the first pushing surface to respectively tightly press the two first support seats, improving the support effect on the two side molds.
[0020] Optionally, each of the first support seats is provided with a positioning post. One end of the docking rod away from the second support seat is provided with a second socket. One end of the second socket is for the positioning post to be inserted and fitted, and the other end is for the top support sleeve to be inserted and fitted. Each of the first support seats is provided with an abutting block which has an abutting surface. When the second socket is sleeved on the positioning post, the abutting surface abuts against the outer peripheral wall of the second socket. The abutting block is provided with a limiting component which is used to force the second socket to remain sleeved on the positioning post.
[0021] By adopting the above technical solution, when the docking rod is connected to the first support seat, the second socket can be sleeved on the positioning post of the first support seat from top to bottom, so that the docking rod can be connected to the first support seat, improving the disassembly and assembly convenience between the docking rod and the first support seat, and further improving the disassembly and assembly convenience between the first support seat and the second support seat. At the same time, after the second socket is sleeved on the positioning post, the second socket can be used for the top support sleeve to be inserted, that is, according to actual needs, a top support member can be added to the second socket to better support the top die. The setting of the abutting block increases the contact area between the first support seat and the second socket, reducing the possibility of deformation of the positioning post when the docking rod presses against the positioning post.
[0022] Optionally, a first limiting groove is formed in the abutting surface, and a second limiting groove is formed in the outer peripheral wall of the second socket. The limiting component includes a limiting block, a limiting spring and a pull rod. The limiting block is slidably installed in the first limiting groove, and the limiting spring is arranged in the first limiting groove. Under normal conditions, the limiting spring forces the limiting block to partially insert into the second limiting groove. A third limiting groove for the limiting block to be embedded is formed in the outer peripheral wall of one end of the top support sleeve away from the top support rod. One end of the pull rod is connected to the limiting block, and the other end passes through to the side of the abutting block away from the positioning post and is connected with a pull ring.
[0023] By adopting the above technical solution, when the second socket is connected to the positioning post, the pull rod is pulled through the pull ring to move the limiting block into the first limiting groove, and then the second socket is sleeved on the positioning post. At this time, the pull ring is released, and the limiting block can be embedded into the second limiting groove under the action of the limiting spring, realizing the limiting effect on the second socket and improving the connection stability between the first support seat and the second support seat. When a top support member needs to be added to the second socket, the limiting block is pulled through the pull ring, and then the top support sleeve is inserted into the second socket and forced to make the third limiting groove face the second limiting groove. At this time, the pull ring is released, and the limiting block can pass through the second limiting groove and be embedded into the third limiting groove, that is, realizing the limiting effect on the second socket, realizing the limiting effect on the top support sleeve, and also realizing the anti-rotation effect on the top support sleeve, reducing the possibility of free rotation of the top support sleeve during the process of rotating the adjusting head, and improving the operation convenience of the overall structure.
[0024] Optionally, a rotating rod is provided at one end of the diagonal brace close to the first support base. The rotating rod is rotatably connected to the first support base, and the diagonal brace is rotatably installed on the first support base through the rotating rod. A lifting block for the top support sleeve to abut against is slidably installed on the positioning post. An extrusion strip is provided between the lifting block and the first support base. When the top support sleeve abuts tightly against the lifting block, the lifting block forces the extrusion strip to abut tightly against the rotating rod.
[0025] By adopting the above technical solution, after the top support sleeve is inserted into the second socket, the lower end of the top support sleeve abuts against the lifting block. When the adjusting head is tightened, the top support sleeve can be forced to press tightly against the lifting block. The lifting block can drive the extrusion strip to move downward to abut tightly against the rotating rod of the diagonal brace, restricting its free rotation and increasing the stability of the overall structure.
[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the arrangement of the support strip and the support plate, the support plate is installed in the support area through the connecting piece. After the top mold and the side mold are built and supported and fixed by the top support member and the diagonal support member respectively, the steel bar truss and the steel plate are built in the top mold, and the steel bars are tied in the side mold. Then, concrete is poured into the top mold and the side mold. When the concrete reaches the design strength (the concrete is not completely solidified), the support plate can be detached through the connecting piece, while the top support member and the diagonal support member are retained, greatly shortening the use turnover cycle of the support plate, enabling the support plate to be used in the next construction link faster, reducing the expenditure of the overall project cost, and improving the construction efficiency; 2. Through the arrangement of the docking assembly, the second support base is arranged between the first support bases corresponding to the two side molds through the docking assembly to connect the two first support bases in series. The reaction forces (the reaction forces from the respective corresponding diagonal support members) received by the two first support bases can cancel each other out in the second support base, achieving force balance and improving the stability of the overall structure; 3. Through the arrangement of the limiting assembly, when the second socket is connected to the positioning post, the pull rod is pulled through the pull ring to move the limiting block into the first limiting groove. Then, the second socket is sleeved on the positioning post. At this time, the pull ring is released, and the limiting block can be embedded in the second limiting groove under the action of the limiting spring, realizing the limiting effect on the second socket and improving the connection stability between the first support base and the second support base. When a top support member needs to be installed on the second socket, the limiting block is pulled through the pull ring, and then the top support sleeve is inserted into the second socket and forced to align the third limiting groove with the second limiting groove. At this time, the pull ring is released, and the limiting block can pass through the second limiting groove and be embedded in the third limiting groove, realizing the limiting effect on the second socket, the limiting effect on the top support sleeve, and the anti-rotation effect on the top support sleeve, reducing the possibility of the top support sleeve rotating freely during the process of rotating the adjusting head, and improving the operation convenience of the overall structure.

[0030] Embodiment 1: An embodiment of the present application discloses a detachable aluminum alloy bottom formwork truss floor slab formwork support system.
[0031] Refer to Figure 1 、 Figure 2 As shown in
[0032] Refer to Figure 1 , Figure 3 ,the top support surface 11 includes support bars 12 and support plates 13. A plurality of support bars 12 are arranged side by side. There is an interval between adjacent two support bars 12 to form a support area 121. The support plates 13 are arranged in the support area 121, and the number of support plates 13 in each support area 121 is multiple. The multiple support plates 13 are arranged in sequence along the length direction of the support bars 12. The multiple support plates 13 and the multiple support bars 12 are combined to form the top support surface 11.
[0033] The support plate 13 is made of aluminum alloy. A reinforcing convex edge 131 is fixedly installed on the plate surface of the support plate 13. The reinforcing convex edge 131 is annular around the edge of the plate surface of the support plate 13. Reinforcing ribs 132 are installed inside the reinforcing convex edge 131. The two ends of the reinforcing ribs 132 are respectively fixedly connected to two opposite inner side walls of the reinforcing convex edge 131. There is an interval between the reinforcing ribs 132 and the plate surface of the support plate 13 to form an operation gap 133.
[0034] Refer to Figure 3 ,a connecting piece is arranged between the support plate 13 and the support bar 12. The support plate 13 is detachably installed on the support bar 12 through the connecting piece. In this embodiment, a first connection hole is opened on the side wall of the support bar 12, and a second connection hole is opened on the side wall of the reinforcing convex edge 131 of the support plate 13. The connecting piece includes a connecting bolt 14 and a connecting nut. The connecting bolt 14 sequentially passes through the first connection hole of the support bar 12 and the second connection hole of the reinforcing convex edge 131. The connecting nut (not shown in the figure) is sleeved on the connecting bolt 14 and is threadedly connected to the connecting bolt 14.
[0035] Refer to Figure 2 、 Figure 4, It should be noted that in this embodiment, there are two side support surfaces 21 provided on the side mold 2. The two side support surfaces 21 are spaced apart, and the gap between the two side support surfaces 21 is used to fill concrete. An isolation sleeve 22 is installed between the two side support surfaces 21, and a connecting screw 23 is installed inside the isolation sleeve 22. Both ends of the connecting screw 23 penetrate through the two side support surfaces 21 respectively, and locking nuts 24 are threadedly sleeved on both ends of the connecting screw 23. The top support member 3 is used to support the support strip 12 of the top support surface 11, and the inclined support member 4 is used to support the support strip 12 of the side support surface 21. In this embodiment, inclined support members 4 need to be correspondingly provided for the two side support surfaces 21 of the side mold 2 (only the inclined support member 4 of one side support surface 21 is shown in the figure).
[0036] Refer to Figure 2 , Figure 4 , a first support base 5 is provided at the bottom of the top mold 1. In this embodiment, the first support base 5 is connected to the ground or the floor slab by bolts. The inclined support member 4 includes an inclined support sleeve 41, an inclined support rod 42, and an inclined support head 43. There are two inclined support rods 42, and the two inclined support rods 42 are respectively inserted into both ends of the inclined support sleeve 41. The inclined support sleeve 41 is threadedly connected to both of the two inclined support rods 42 (the threads are not shown in the figure), and the thread directions of the inclined support sleeve 41 and the two inclined support rods 42 are opposite to each other.
[0037] One end of one inclined support rod 42 away from the inclined support sleeve 41 is connected to the first support base 5, and the other end of the other inclined support rod 42 away from the inclined support sleeve 41 is connected to the inclined support head 43. The inclined support head 43 is used to connect the support strip 12 of the side support surface 21; it should be noted that in this embodiment, the inclined support head 43 and the inclined support rod 42, the inclined support head 43 and the support strip 12, and the inclined support rod 42 and the first support base 5 are all detachably installed in the form of bolt connections.
[0038] Refer to Figure 2 , Figure 4 , the top support member 3 includes a top support sleeve 31, a top support rod 32, and a top support head 33. The top support sleeve 31 is vertically arranged. In this embodiment, the top support sleeve 31 is a tubular structure with an open upper end and a closed lower end. One end of the top support rod 32 is inserted into the top support sleeve 31, and the other end is connected to the top support head 33. The top support head 33 is used to connect the support strip 12 of the top support surface 11, and the top support head 33 and the support strip 12 are detachably installed in the form of bolt connections; a regulating head 311 is rotatably installed at one end of the top support sleeve 31 close to the top support rod 32, and the top support rod 32 passes through the regulating head 311 and is threadedly connected to the regulating head 311 (the threads are not shown in the figure).
[0039] The implementation principle of Embodiment 1 of this application is as follows: The support plate 13 is installed in the support area 121 through a connecting piece. After the top formwork 1 and the side formwork 2 are erected and supported and fixed respectively by the top support piece 3 and the inclined support piece 4, the steel bar truss and the steel plate are erected in the top formwork 1, and the steel bars are tied in the side formwork 2. Then, concrete is poured into the top formwork 1 and the side formwork 2. When the concrete reaches the design strength (the concrete is not completely solidified), the support plate 13 can be detached through the connecting piece, while the top support piece 3 and the inclined support piece 4 are retained, greatly shortening the use turnover cycle of the support plate 13, enabling the support plate 13 to be used in the next construction link faster, reducing the expenditure of the overall project cost, and improving the construction efficiency.
[0040] The arrangement of the reinforcing convex edge 131 and the reinforcing rib 132 improves the structural strength of the support plate 13 and reduces the possibility of deformation of the support plate 13. The reinforcing rib 132 is arranged at intervals with the plate surface of the support plate 13 to form an operation gap 133. On the one hand, the reservation of the operation gap 133 can facilitate the insertion of the worker's hand, thus facilitating the handling and transfer of the support plate 13; on the other hand, when the support plate 13 can be removed, the operation gap 133 can be used for the hook to extend and be hooked, so as to facilitate the detachment of the support plate 13.
[0041] Embodiment 2: This application embodiment discloses a detachable aluminum alloy bottom formwork truss floor slab formwork support system.
[0042] The difference between the detachable aluminum alloy bottom formwork truss floor slab formwork support system disclosed in this application embodiment and Embodiment 1 lies in: Refer to Figure 5 、 Figure 6 、 Figure 7 In this embodiment, there are two side formworks 2, and both sides of the top formwork 1 are lapped on the two side formworks 2 respectively. Under this working condition, the above-mentioned first support seats 5 are correspondingly arranged on both side formworks 2, and a second support seat 6 is installed between the first support seats 5 corresponding to the two side formworks 2. The second support seat 6 is provided with a docking component 7, and the second support seat 6 is installed between the first support seats 5 corresponding to the two side formworks 2 through the docking component 7.
[0043] The docking component 7 includes a docking rod 71 and an opposing member. There are two docking rods 71, and the two docking rods 71 are correspondingly arranged with the two first support seats 5. One end of each docking rod 71 is connected to the second support seat 6, and the other end is connected to the corresponding first support seat 5. The second support seat 6 is connected to the two first support seats 5 respectively through the two docking rods 71. A positioning post 51 is fixedly installed on each first support seat 5. A second socket 74 is fixedly installed at the end of the docking rod 71 away from the second support seat 6. The lower end of the second socket 74 is for the positioning post 51 to be inserted and fitted. One end of the docking rod 71 is connected to the positioning post 51 of the corresponding first support seat 5 through the second socket 74; the other end of the second socket 74 is for the top support sleeve 31 to be inserted and fitted.
[0044] Referring to Figure 5 、 Figure 6 , an installation cavity 62 is formed in the second support seat 6, and a communication groove 63 communicating with the installation cavity 62 is formed in the top wall of the second support seat 6. The opposing member is arranged in the second support seat 6. The opposing member is used to force the two docking rods 71 to move away from each other. The opposing member includes a driving block 72 and an opposing block 73. The driving block 72 is slidably installed in the installation cavity 62 and can slide in the height direction. A first socket 61 for the top support sleeve 31 to be inserted is provided on the second support seat 6. In this embodiment, the first socket 61 is a tubular structure with an open top and a closed bottom. A rotating head 611 is integrally formed on the outer peripheral wall of the first socket 61. The cross-sectional shape of the rotating head 611 is polygonal for docking tools such as a wrench; a non-rotating head 612 is integrally formed on the inner wall of the first socket 61. The cross-sectional shape of the non-rotating head 612 is polygonal. A non-rotating groove 313 is formed on the lower end surface of the top support sleeve 31. The shape of the non-rotating groove 313 is adapted to the shape of the non-rotating head 612; the first socket 61 passes through the communication groove 63 and is threadedly connected to the inner wall of the connection groove (the thread is not shown in the figure). The lower end of the first socket 61 extends into the installation cavity 62 and is rotatably connected to the driving block 72.
[0045] Referring to Figure 6 , there are two opposing blocks 73. The two opposing blocks 73 are both slidably installed in the installation cavity 62 and can slide in the horizontal direction. The two opposing blocks 73 are correspondingly arranged with the two docking rods 71. One end of each docking rod 71 extends into the installation cavity 62 and is fixedly connected to the corresponding opposing block 73; the driving block 72 has a first pushing surface 721, and the opposing block 73 has a second pushing surface 731 for the first pushing surface 721 to abut against. When the driving block 72 moves downward, the two opposing blocks 73 move away from each other.
[0046] It should be noted that in other embodiments, the structure of the docking rod 71 can be set as a telescopic structure. The telescopic structure can refer to the structure of the diagonal brace 42 and the diagonal brace sleeve 41. By setting the docking rod 71 as a telescopic structure, the distance between the first support seat 5 and the second support seat 6 can be adjusted.
[0047] The implementation principle of Embodiment 2 of this application is as follows: The second support base 6 is connected to the two first support bases 5 through two docking rods 71, thereby "connecting in series" the two first support bases 5. By means of the opposing member, the two docking rods 71 are forced to move away from each other to abut against the corresponding first support base 5, enabling the two first support bases 5 to be in balanced force, and thus improving the support effect on the side mold 2.
[0048] After the second support base 6 abuts against the two first support bases 5, the jacking member 3 is installed in the first socket 61. On the one hand, the first socket 61 serves as a mounting carrier for the jacking sleeve 31 to limit the jacking sleeve 31. On the other hand, when the jacking member 3 supports the jacking surface 11, the jacking member 3 exerts a downward pressure on the first socket 61. This pressure can keep the first socket 61 in a tightened state, reducing the possibility of the first socket 61 rotating freely, and thus enabling the second support base 6 to remain in abutment against the two first support bases 5, greatly improving the stability of the overall structure.
[0049] Both the first socket 61 and the second socket 74 are used for the jacking sleeve 31 to be inserted. In actual application, when the distance between the two side molds 2 is less than 3 m, the jacking member 3 can be installed in the first socket 61, and the jacking member 3 may not be installed in the two second sockets 74.

The abutting block 52 has an abutting surface 521. When the second socket 74 is sleeved on the positioning post 51, the abutting surface 521 abuts against the outer peripheral wall of the second socket 74; the abutting block 52 is provided with a limiting component 8, and the limiting component 8 is used to force the second socket 74 to remain sleeved on the positioning post 51.
[0052] The abutting surface 521 is provided with a first limiting groove 522, and the outer peripheral wall of the second socket 74 is provided with a second limiting groove 741. When the second socket 74 is sleeved on the positioning post 51, the first limiting groove 522 is directly opposite to the second limiting groove 741; the limiting component 8 includes a limiting block 81, a limiting spring 82 and a pull rod 83. The limiting block 81 is slidably installed in the first limiting groove 522, the limiting spring 82 is arranged in the first limiting groove 522, one end of the limiting spring 82 is fixedly connected to the inner wall of the first limiting groove 522, and the other end is fixedly connected to the limiting block 81. Under normal conditions, the limiting spring 82 forces the limiting block 81 to partially insert into the second limiting groove 741, and a third limiting groove 312 for the limiting block 81 to embed is provided on the outer peripheral wall of the end of the top support sleeve 31 away from the top support rod 32; one end of the pull rod 83 is fixedly connected to the limiting block 81, and the other end passes out to the side of the abutting block 52 away from the positioning post 51 and is fixedly connected with a pull ring 84.
[0053] The implementation principle of Embodiment 3 of this application is as follows: when the second socket 74 is connected to the positioning post 51, the pull rod 83 is pulled through the pull ring 84 to move the limiting block 81 into the first limiting groove 522, and then the second socket 74 is sleeved on the positioning post 51. At this time, the pull ring 84 is released, and the limiting block 81 can be embedded in the second limiting groove 741 under the action of the limiting spring 82, realizing the limiting effect on the second socket 74 and improving the connection stability between the first support base 5 and the second support base 6.
[0054] When the top support member 3 needs to be installed on the second socket 74, the limiting block 81 is pulled through the pull ring 84, and then the top support sleeve 31 is inserted into the second socket 74, and the third limiting groove 312 is forced to be directly opposite to the second limiting groove 741. At this time, the pull ring 84 is released, and the limiting block 81 can pass through the second limiting groove 741 and be embedded in the third limiting groove 312, realizing the limiting effect on the second socket 74, the limiting effect on the top support sleeve 31, and the anti-rotation effect on the top support sleeve 31, reducing the possibility of the top support sleeve 31 rotating freely during the process of rotating the adjustment head 311, and improving the operation convenience of the overall structure.
[0055] Embodiment 4: This application embodiment discloses a detachable aluminum alloy bottom formwork truss floor slab formwork support system.
[0056] The difference between the detachable aluminum alloy bottom formwork truss floor slab formwork support system disclosed in this application embodiment and Embodiment 3 is as follows: Refer to Figure 9 、 Figure 10, in this embodiment, a rotating rod 421 is fixedly installed on the outer peripheral wall of one end of the diagonal brace 42 close to the first support base 5. Both ends of the rotating rod 421 are rotatably connected to the first support base 5, and the diagonal brace 42 is rotatably installed on the first support base 5 through the rotating rod 421. A lifting block 511 for the top support sleeve 31 to abut against is slidably installed on the positioning post 51. A pressing strip 512 is slidably installed on the side wall of the first support base 5. The bottom wall of the pressing strip 512 has a pressing arc surface 514 for abutting against the rotating rod 421. In this embodiment, two pressing strips 512 are provided, and the two pressing strips 512 are symmetrically distributed on two opposite inner walls of the first support base 5. Both ends of the lifting block 511 are fixedly connected to the two pressing strips 512 respectively. It should be noted that the second socket 74 needs to be provided with an avoidance groove (not shown in the figure) for the lifting block 511 to pass through.
[0057] A return spring 513 is installed between the pressing strip 512 and the inner wall of the first support base 5. One end of the return spring 513 is fixedly connected to the pressing strip 512, and the other end is fixedly connected to the inner wall of the first support base 5. Under normal conditions, the return spring 513 forces the pressing strip 512 to lift, so that the pressing arc surface 514 of the pressing strip 512 disengages from the rotating rod 421 of the diagonal support sleeve 41; when the top support sleeve 31 abuts tightly against the lifting block 511, the lifting block 511 moves downward and drives the pressing arc surface 514 of the pressing strip 512 to abut tightly against the rotating rod 421; it should be noted that in this embodiment, the third limiting groove 312 is a strip-shaped groove, and both ends of the third limiting groove 312 extend along the length direction of the top support sleeve 31.
[0058] The implementation principle of Embodiment 4 of this application is as follows: after the top support sleeve 31 is inserted into the second socket 74, the lower end of the top support sleeve 31 abuts against the lifting block 511. When the adjusting head 311 is tightened, the top support sleeve 31 is forced to tightly press the lifting block 511. The lifting block 511 can drive the pressing strip 512 to move downward to abut tightly against the rotating rod 421 of the diagonal brace 42, restricting its free rotation, thereby further increasing the stability of the overall structure.
[0059] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
