Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a floor slab support system suitable for aluminum alloy formwork construction. Background Technology

[0002] In the construction of concrete building structures, the support system consisting of aluminum alloy formwork and independent supports is one of the commonly used construction methods.

[0003] Aluminum formwork support systems are characterized by high overall rigidity and good construction quality, but their cost is higher compared to support systems composed of disc-lock scaffolding and wooden formwork. At the same time, aluminum formwork installation nodes are complicated, and the installation and early dismantling efficiency is low. The lack of adjustment tolerance in aluminum formwork installation often leads to positional conflicts in the construction of prefabricated concrete structures, which greatly reduces on-site construction efficiency. The aluminum formwork, keel, and other supporting structures are connected by pins and pin plates, resulting in a large number of connection nodes and low installation efficiency. When dismantling the formwork, the aluminum formwork must be removed first, followed by the keel (equivalent to the main back rib in this patent). Since there are no early-release components between the aluminum formwork and the keel, dismantling is quite difficult. The aluminum formwork keel has a straight early-release head, and when connecting the aluminum formwork and the keel, the early-release heads need to be staggered, which makes the independent support susceptible to large eccentric loads.

[0005] In some possible implementations, an adjustable back rib is provided between the main back rib and the aluminum mold C-channel plate parallel to the main back rib. The adjustable back rib is connected to the aluminum mold C-channel plate by a back rib connector. The adjustable back rib is connected to the adjacent main back rib by a mounting component. The adjustable back rib, which is on the same straight line as the main back rib, is connected to the vertical support adjustment component.

[0006] In some possible implementations, the back rib connector includes a support portion with a U-shaped groove for mounting an adjustable back rib or a main back rib, an end flange for connecting the support portion and the aluminum mold C-channel plate and arranged symmetrically, and a connecting plate installed on the end flange and the top of the support portion for supporting the plate mold.

[0010] In some possible implementations, the mounting component includes an L-shaped support plate mounted on the side of the main back rib along its length and in an L-shape, and a limiting member disposed on the L-shaped support plate for restricting the movement of the secondary back rib along the length of the main back rib.

[0011] In some possible implementations, the L-shaped support plate includes a support plate and a vertical plate mounted on the support plate and forming an L-shape with the support plate; the limiting member is disposed on the side of the support plate away from the support plate; The limiting component includes a rivet installed on the support plate and a limiting plate fitted on the outside of the rivet.

[0012] In some possible implementations, the vertical support adjustment assembly includes a vertical adjustment support, an early removal head mounted on the vertical adjustment support and connected to the main back rib and the adjustable back rib; the early removal head includes a support seat fitted on the outside of the vertical adjustment support and connected to one end of the main back rib or the adjustable back rib, and a top plate mounted on the top of the vertical adjustment support.

During unloading, by rotating the handle, the primary and secondary back ribs deform under their own weight, and the secondary back ribs can be quickly removed from the side, which is more efficient than aluminum molds. The new type of mold can use wooden templates, which, compared with the aluminum molds in the prior art, uses less aluminum material and is lighter, thus reducing the workload of workers.

[0017] The present invention will now be described in detail.

[0018] like Figures 1-9 As shown: A floor slab under-support system suitable for aluminum alloy formwork construction is located within and connected to the aluminum formwork C-channel plate 10. Specifically, there are four sets of aluminum formwork C-channel plates 10, which are sequentially spliced ​​to form a square cavity; the floor slab under-support system will be located within this cavity. The floor slab support system includes a formwork support unit 1 installed in a cavity for installing the formwork, and multiple sets of vertical support adjustment components 2 for supporting the formwork support unit 1. The vertical support adjustment components 2 are used to control the height of the formwork support unit 1, thereby enabling support for formwork at different floor heights. The plate mold support unit 1 includes a main back rib 11 installed on the vertical support adjustment assembly 2 and a secondary back rib 12 for plate mold support and connected to the main back rib 11; a support cavity 13 is formed between multiple sets of the main back ribs 11 or between multiple sets of the main back ribs 11 and the aluminum mold C-channel plate 10, and the secondary back rib 12 is located in the support cavity 13. Specifically, at the mid-span position, one end of each of the four main back ribs 11 will be installed on one of the four vertical support adjustment components 2. The four main back ribs 11 cooperate to form a support cavity 13 for installing the secondary back ribs 12. Multiple secondary back ribs 12 are located in the support cavity 13, and the multiple secondary back ribs 12 are parallel to two of the main back ribs 11 that are arranged in parallel. At the side span position, two sets of main back ribs 11 form an L-shaped structure through a set of vertical support adjustment components 2, or three sets of main back ribs 11 are connected through two sets of vertical support adjustment components 2 to form a U-shaped structure. The above-mentioned structure will be connected with two sets or one set of aluminum mold C-channel plates 10 to form a support cavity 13 for installing secondary back ribs 12. One end of the secondary back rib 12 will be connected to the aluminum mold C-channel plate 10. When there are two sets of main back ribs 11 and two sets of aluminum mold C-channel plates 10, the ends of the two sets of main back ribs 11 away from the vertical support adjustment components 2 will be connected to the two sets of aluminum mold C-channel plates 10. The secondary back ribs 12 are used for the installation of the plate mold. Multiple sets of equally spaced and parallel secondary back ribs 12 will be set in each support cavity 13. The plate mold is installed on the secondary back ribs 12, and the top surface of the plate mold is coplanar with the top surface of the main back ribs 11 and the aluminum mold C-channel plate 10. In order to effectively connect the aluminum mold C-channel plate 10 with the main back rib 11, a back rib connector 15 is provided on the aluminum mold C-channel plate 10 to connect with the main back rib 11. In order to effectively realize the installation of the secondary back rib 12, multiple sets of mounting parts 16 for installing the secondary back rib 12 are respectively provided on the main back rib 11 and the aluminum mold C-channel plate 10 connected to the secondary back rib 12 along its length direction. The mounting parts 16 on the main back rib 11 are evenly arranged along the length direction of the main back rib 11.

[0019] In some possible implementations, during actual construction, since the lengths of the main back rib 11 and the secondary back rib 12 are already determined, when the cavity size changes, a space will be formed between the main back rib 11, which is close to the aluminum mold C-channel plate 10, and the aluminum mold C-channel plate 10. In order to enable the plate mold to be installed effectively in this space, an adjustable back rib 14 is provided between the main back rib 11 and the aluminum mold C-channel plate 10 parallel to the main back rib 11. The adjustable back rib 14 in the same space and on the same straight line as the main back rib 11 is connected to the vertical support adjustment component 2, and the other adjustable back ribs 14 are connected to the adjacent main back ribs 11 through the mounting component 16.

[0020] The adjustable back rib 14 allows the length of the adjustable back rib 14 to be adjusted according to the width of the space formed during construction, thereby achieving the connection between the main back rib 11 of the aluminum formwork C-channel plate 10 and the aluminum formwork C-channel plate 10. Specifically, the adjustable back rib 14 includes an inner tube 142 connected to the aluminum mold C-channel plate 10 at one end via a back rib connector 15, an outer tube 141 fitted on the outside of the inner tube 142 and connected to the vertical support adjustment assembly 2 or the main back rib 11, an end 143 disposed at one end of the inner tube 142 and the outer tube 141 that are far apart from each other, and a locking member for locking the outer tube 141 and the inner tube 142. In the same space, the outer tube 141 of the adjustable back rib 14, away from the inner tube 142, is connected to the main back rib 11 or the vertical support adjustment assembly 2 via the mounting piece 16; the inner tube 142 and the outer tube 141 can be telescopically coupled along their axial direction, thereby enabling the length of the adjustable back rib 14 to be adjusted according to the width of the formed space.

[0021] In some possible implementations, the back rib connector 15 includes a support part 151 with a U-shaped groove for mounting an adjustable back rib 14 or a main back rib 11, an end flange 152 for connecting the support part 151 and the aluminum mold C-channel plate 10 and arranged symmetrically, and a connecting plate 153 installed on the top of the end flange 152 and the support part 151 for supporting the plate mold. Specifically, the end flange 152 is installed on both sides of the support 151 and is integrally formed with the support 151, connecting and fixing the support 151 to the adjustable back rib 14 or the main back rib 11; the opening of the U-shaped bracket is upward, and during installation, one end of the adjustable back rib 14 or the main back rib 11 is placed directly in the U-shaped bracket from the top. One outer side of the support part 151 is connected to the end flange 152 to form an L-shaped structure. The connecting plate 153 is set on the top of the L-shaped structure. This arrangement will greatly increase the support area for the plate mold and prevent the plate mold from falling off.

[0022] In some possible implementations, in order to effectively achieve rapid positioning and assembly of the U-shaped bracket with the adjustable back rib 14 or the main back rib 11, a positioning hole 1511 is provided at the bottom of the U-shaped bracket to cooperate with the adjustable back rib 14 or the main back rib 11; and a positioning boss 111 is provided at the end 143 of the inner tube 142 in the adjustable back rib 14 and at each group of main back ribs 11 to cooperate with the positioning hole 1511.

[0023] In some possible implementations, in order to effectively connect the support part 151 with the adjustable back rib 14 or the main back rib 11, the end of the adjustable back rib 14 or the main back rib 11 is installed in a U-shaped bracket and connected to the support part 151 by a pin 155. The axial direction of the pin 155 is arranged along the length direction of the aluminum mold C-groove plate 10 on which the back rib connector 15 is installed. The adjustable back rib 14 and the main back rib 11 are respectively provided with pin holes that cooperate with the pin 155. In order to effectively realize the detachable connection between the back rib connector 15 and the aluminum mold C-channel plate 10, and thus enable the connection position of the two to be adjusted according to the usage requirements, the end flange 152 and the aluminum mold C-channel plate 10 are connected and fixed by a pin 154.

[0024] In some possible implementations, in order to effectively achieve quick assembly and disassembly of the back rib connector 15 and the aluminum mold C-groove plate 10 through the pin 154, the pin 154 includes a pin 1541 with one end passing through the aluminum mold C-groove plate 10 and the end flange 152 in sequence, and a wedge 1542 mounted on the pin 1541 and located on the side of the end flange 152 away from the aluminum mold C-groove plate 10. A through hole for inserting the wedge 1542 is provided on the pin 1541. The pin 1541 is in the form of a large and small head, with a through hole located on the side near the small head. The end with the small head passes through the aluminum mold C-slot plate 10 and the end flange 152 in sequence, and the through hole also passes through the aluminum mold C-slot plate 10 and the end flange 152. Then, the wedge 1542 is inserted into the through hole, and the side of the wedge 1542 near the end flange 152 abuts against the end flange 152, thereby connecting the back rib connector 15 to the aluminum mold C-slot plate 10.

[0025] In some possible implementations, the mounting member 16 includes an L-shaped support plate 161 mounted on the side of the main back rib 11 along its length direction and in an L-shape, and a limiting member 162 disposed on the L-shaped support plate 161 for limiting the movement of the secondary back rib 12 along the length direction of the main back rib 11. Furthermore, a support plate is provided on the L-shaped support plate 161. The support plate is used to support the plate mold and increase the contact area between the plate mold and the L-shaped support plate 161. The limiting member 162 will effectively prevent the secondary back rib 12 from slipping off the L-shaped support plate 161.

[0026] In some possible implementations, the L-shaped tray 161 includes a support plate 1611 and a vertical plate 1612 mounted on the support plate 1611 and forming an L-shaped structure with the support plate 1611; the limiting member 162 is disposed on the side of the support plate 1611 away from the support plate 1611. The limiting member 162 includes a rivet installed on the support plate 1611 and a limiting plate fitted on the outside of the rivet; After the secondary back rib 12 is installed, the rotating limiting plate makes the limiting plate cooperate with the vertical plate 1612 to restrict the movement of the secondary back rib 12 along the length direction of the main back rib 11; when the secondary back rib 12 is removed, the secondary back rib 12 can be removed from the side of the L-shaped support plate 161 by rotating the limiting member 162. Furthermore, a connecting plate is provided on the side of the support plate 1611 away from the vertical plate 1612, and the rivets will be connected to the connecting plate.

[0027] In some possible implementations, the vertical support adjustment assembly 2 includes a vertical adjustment support, an early removal head 24 mounted on the vertical adjustment support and connected to the main back rib 11 and the adjustable back rib 14; the early removal head 24 includes a support base 241 fitted on the outside of the vertical adjustment support and connected to one end of the main back rib 11 or the adjustable back rib 14, and a top plate 242 mounted on the top of the vertical adjustment support. Specifically, in the middle span, the early dismantling head 24 will be connected to the ends of the four main back ribs 11, so that the four main back ribs 11 form a support cavity 13; in the side span, the early dismantling head 24 will be connected to the three main back ribs 11 and the one adjustable back rib 14, or the early dismantling head 24 will be connected to the two main back ribs 11. The top plate 242 maintains its support for the floor slab after the main back rib 11 and the secondary back rib 12 are removed. After assembly, the formwork, the main back rib 11, and the top plate 242 will be on the same plane. During early dismantling, the secondary back rib 12 and the main back rib 11 will be removed in sequence, and the floor slab will be supported by the vertical adjustment support in conjunction with the top plate 242.

[0028] To make the vertical adjustment support adjustable, the vertical adjustment support includes an outer rod 21, an inner rod 22 fitted inside the outer rod 21 and extending and retracting along the axial direction of the outer rod 21, and a rotating handle 23 fitted outside the inner rod 22 for supporting a support base 241. The top plate 242 is installed on the top of the inner rod 22; the support base 241 is fitted outside the inner rod 22; and the rotating handle 23 is screwed into the inner rod 22. The inner rod 22 is fitted inside the outer rod 21 to achieve telescopic cooperation. After the overall height is adjusted to the required height, the two can be fixed. The top of the rotating handle 23 abuts against the bottom of the support base 241. During early disassembly, by turning the rotating handle 23, the support base 241 is moved away from the floor slab along the axial direction of the inner rod 22, thereby adjusting the position of the main back rib 11, the secondary back rib 12, and the adjustable back rib 14 to achieve disassembly.

[0029] In some possible implementations, the support base 241 is provided with four sets of cross-shaped grooves 2411 for connecting the four sets of grooves 2411 and for installing the central cavity of the top plate 242; the central cavity is coaxially arranged with the inner rod 22; a positioning through hole 243 is provided at the bottom of the groove 2411; the main back rib 11 and the adjustable back rib 14 are respectively connected to the support base 241 via pin A244; the positioning through hole 243 will cooperate with the positioning boss 111 to realize the quick positioning and installation of the main back rib 11 or the adjustable back rib 14 with the support base 241; the pin A244 and the pin 155 have the same structural dimensions; the end of the outer tube 141 of the adjustable back rib 14, which cooperates with the groove 2411, will be provided with a positioning boss 111 that cooperates with the positioning through hole 243 to achieve positioning; Preferably, the positioning hole 1511 and the positioning through hole 243 have the same structure and are both tapered holes; the positioning boss 111 has a tapered structure and is adapted to the tapered hole.

[0030] In this invention, the pin A244 and the positioning through hole 243 are used to form two support points at the top and bottom, thereby achieving near-rigid in-plane constraint. At the same time, it has high installation and disassembly efficiency. When installing the main back rib 11, it is only necessary to align the positioning boss 111 with the positioning through hole 243 first, and then quickly align the through pin A244 to complete the connection between the main back rib 11 and the early removal head 24. When removing the main back rib 11 and the secondary back rib 12, first remove the pins A244 around the perimeter. Since the positioning through hole 243 is slightly larger than the positioning boss 111, turn the rotating handle 23 to gently vibrate the early removal head 24, and the early removal head 24 will fall down accordingly, achieving the purpose of rapid early removal.

[0031] Specifically, when using a floor slab support system for construction, taking wooden formwork as an example: First, mark the lines and positions before installing the formwork and supports, and then install the aluminum formwork for the walls, columns and beams. Then, using the C-groove at the inside corner of the wall and beam as the boundary, install the main back rib 11 and the vertical support adjustment component 2 one by one, and adjust the elevation. First, complete the installation of all the main back ribs 11 and the vertical support adjustment component 2. Secondary back bracing 12 and adjustable back bracing 14 are laid and installed at the location of the cast-in-place strip of the cast-in-place floor slab or prefabricated composite slab, and the limiting piece 162 on the L-shaped bracket of the main beam is turned to prevent the side of the secondary beam from falling off. Wooden templates are laid on the secondary back ribs 12 and adjustable back ribs 14, and the template joints are reinforced and sealed with long strips of wood and adhesive strips. After installing the composite slabs, tying the reinforcing bars, and pouring the concrete, the support frame will be dismantled once the floor slabs have reached the predetermined strength. When dismantling, turn the rotating handles 23 on all independent supports downward by 1-2cm, and then dismantle them sequentially from the middle of the support to the periphery of the aluminum mold C-channel plate 10. First, remove the secondary back ribs 12 between the main back ribs 11, unscrew the rotating limit piece 162 of the L-shaped bracket, take out the secondary back ribs 12 from the side, and then remove the adjustable back ribs 14 connected to the aluminum mold C-channel plate 10 and the main back ribs 11. After removing the secondary back rib 12 and the adjustable back rib 14, remove the main back rib 11 and the wooden template in the order from the middle to the edge to complete the early dismantling work.

[0032] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
