Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and in particular relates to a support unit and a system suitable for an assembled concrete frame shear wall structure. Background Art

[0002] Whether it is a cast-in-place structure or a prefabricated structure, the construction of the formwork support structure is an important part of engineering construction, and plays a key role in the control of construction speed, quality cost and construction safety.

[0003] For example, a Chinese patent (publication number: CN117846288A) discloses a support unit and system suitable for the construction of prefabricated concrete frame structures, wherein the support unit includes multiple groups of under-beam support units that are sequentially connected and enclosed to form a cavity, and under-plate support units that are located in the cavity and are respectively superimposed with the multiple groups of under-beam support units; the under-plate support unit includes an under-plate support assembly, two groups of superimposed plate back-rib systems installed on the under-plate support assembly, and a plate-strip back-rib system that is respectively connected to the two groups of superimposed plate back-rib systems and is located between the two groups of superimposed plate back-rib systems. In the present invention, the connection between adjacent vertical rods is achieved through horizontal rods under the beams, and the connection between adjacent vertical rods and vertical rods is achieved through horizontal connecting rods to form a support force system. There is a large space at the bottom of the under-beam support unit and the superimposed plate support unit, which is convenient for interlaced construction or safety inspections, and provides a convenient space; it can effectively support the superimposed plate and plate-strip formwork, but there are the following problems in actual application:

[0004] The back rib system has obvious design redundancy and complexity problems: especially in the back rib arrangement area of ​​the wooden formwork below the post-casting strip, the use of a large number of non-standard components not only increases the difficulty of material management, but also brings many inconveniences to the construction workers in the installation work. At the same time, the complex overall connection method makes the system difficult to adjust and cannot meet the needs of fast and precise adjustment during on-site construction, which brings significant challenges to the quality control of engineering construction; The setting method of horizontal connecting rods has obvious shortcomings: the current practice of using two shorter horizontal connecting rods at the same beam position has poor horizontal force transmission effect of the overall structure, and the lack of unified coordination between the arrangement of the support unit under the beam and the support unit under the plate makes it impossible for the horizontal connecting rod to maintain a horizontal state, reducing the overall performance of the plate-beam structure support structure; The setting of the triangular brace was over-designed: too many reinforcement measures were adopted around the edge of the support unit under the composite slab. This caused material waste and increased construction difficulty. In particular, when the length of the support position needed to be adjusted, the existing fixed triangular brace structure was difficult to adapt flexibly, which seriously affected the construction progress and efficiency.

[0005] The existence of these problems affects construction efficiency and quality, and also increases project costs; For example, a Chinese patent (publication number: CN118855219A) discloses a prefabricated floor slab free bottom formwork lattice support structure and construction method, the system includes a lattice frame, a U-shaped top support, a support beam, a composite slab and a cast-in-place floor slab; a plurality of lattice frames are installed on the floor slab of the lower layer of the cast-in-place floor slab at intervals, and a plurality of lattice frames extend upward to the bottom of the cast-in-place floor slab; a U-shaped top support is provided on the top of each lattice frame, so that a plurality of support beams are installed on the top of a plurality of lattice frames through the U-shaped top support; the composite slab is laid on a plurality of support beams, the steel bars of the cast-in-place floor slab are tied on the composite slab, and concrete is poured on the steel bars and the composite slab to form a cast-in-place floor slab. The present invention relates to the field of building construction technology, and can solve the problems of long construction period, high material consumption and great environmental impact in the prior art of floor slab construction. The prefabricated floor slab support structure has the following technical problems:

[0006] In the prefabricated structure using composite slabs, composite beams and prefabricated columns, there are inevitably cast-in-place parts, which mainly include key areas such as connection nodes between components and post-casting strips. These cast-in-place parts must be reasonably arranged with building formwork to complete the concrete pouring. The support structure has the problem of low space utilization efficiency in structural design: although the spacing design between the lattice columns takes into account the passage needs of construction workers, the number of rods in the overall support system is too large, resulting in crowded lower space, which is not conducive to the development of construction work. When the building bay size is slightly larger than the ideal size of the system design, additional lattice columns need to be arranged according to structural safety requirements, which makes the arrangement density of the support system close to the level of traditional full-floor scaffolding; Therefore, a support unit and system suitable for prefabricated concrete frame shear wall structure are needed to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a support unit and system suitable for a prefabricated concrete frame shear wall structure to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a support unit and system suitable for an assembled concrete frame shear wall structure, comprising a plurality of early-dismantling heads, two wall formworks and two support members, an aluminum alloy short beam is connected between the two early-dismantling heads on one side, the sides of the early-dismantling heads on both sides that are far away from each other are connected to the aluminum alloy main beam, and the two corresponding early-dismantling heads in the middle are connected to the aluminum alloy main beam, the bottoms of the early-dismantling heads are connected to independent support rods, the same wooden formwork is provided on the plurality of aluminum alloy short beams on one side, a plurality of rigid supports are overlapped under the wooden formwork, the aluminum alloy main beam and the wooden formwork are provided with a composite plate, the composite plate is provided with a plurality of bolts, and the bolts The bolt passes through the rigid support, and the bottom end of the bolt is threadedly connected with a nut. One end of the aluminum alloy main beam is connected to the internal angle formwork, and the bottom of the internal angle formwork in the middle is connected to the inner side formwork of the beam. The bottoms of the two inner side formworks of the beams in the middle are connected to the same beam bottom formwork. The two corresponding independent support rods in the middle are provided with horizontal rods under the beam. The bottom of the internal angle formworks on both sides is connected to two wall formworks. A side of the wall formwork on one side away from the support is provided with a plurality of wall back ribs, and the same tension screw is connected between the plurality of wall back ribs. The plurality of wall back ribs in the middle are hinged to the top ends of a plurality of small diagonal braces through pins, and the bottoms of the plurality of small diagonal braces are hinged to a plurality of ground nails through pins.

[0009] This technology uses a two-way rigid beam system obtained by simplifying the horizontal bar system and horizontal beams under the beam to replace the original load-bearing beam and part of the horizontal bars under the beam as the overall transmission of horizontal force, solving the problem of "too redundant arrangement of horizontal connecting rods and unclear horizontal force transmission path"; by setting independent support rods, the problem of complex arrangement of vertical poles and the problem of too many rods caused by lattice columns are solved, further reducing the loss of consumables; the support structure realizes horizontal force transmission of the upper load through two-way rigid beams, and realizes vertical force transmission through independent support rod structures, thereby meeting the construction requirements of complex structures, and the support structure retains the advantage of aluminum formwork to realize early removal of formwork, thereby improving construction efficiency.

[0010] As a preferred solution, the tension screw rods are arranged throughout the wall formwork and the support member.

[0011] As a preferred solution, the horizontal bar under the beam is arranged below the inner side formwork of the beam.

[0012] As a preferred solution, the horizontal bar under the beam is arranged between two wall formworks.

[0013] As a preferred solution, the horizontal bar under the beam is arranged between a plurality of rigid supports on both sides.

[0014] As a preferred solution, the material of the rigid support is set to be FRP material.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts a bidirectional rigid beam structure as the template load-bearing beam. The overall force-bearing system formed by the bidirectional rigid beam effectively realizes the optimization of horizontal lateral resistance and anti-overturning performance. The uniqueness of this structural design is that no additional horizontal rod under the beam is required, thereby creating a spacious construction space under the template, significantly improving the working convenience of construction personnel, and enabling workers to walk and perform construction work safely and conveniently. The present invention gives full play to the inherent advantages of the prefabricated components of the composite slab, not only utilizes its excellent strength characteristics, but also fully considers the characteristics of concrete block molding, and significantly reduces the number of templates and support rods used; in the selection of template materials, aluminum alloy internal angle templates, wall templates, beam inner templates, aluminum alloy short beams, aluminum alloy main beams and FRP material rigid supports are used, making full use of the lightweight and high-strength material properties of aluminum alloy, so that the installation process of the reinforced concrete load-bearing beam of the floor slab does not need to rely on lifting equipment, matching the integrated construction of the assembled structure, and is more green and environmentally friendly; The present invention adopts a complete cast-in-place part formwork support scheme to solve the construction requirements of cast-in-place concrete load-bearing walls in prefabricated structures; The present invention adopts an independent support rod form, which significantly simplifies the rod structure of the support structure and ensures the safety and reliability of the support structure; The present invention mainly adopts the construction method of CRFP rigid support hoisting wooden formwork in the post-cast strip between the superimposed plates.

The wooden formwork is not only more economical than the aluminum alloy formwork, but also retains the characteristics of flexible and convenient local cutting and adjustment of the wooden formwork, thereby simplifying the load-bearing beam and support system below.

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the embodiments.

The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0020] See also Figure 1-6 The present invention provides a support unit and system suitable for an assembled concrete frame shear wall structure, including a plurality of early removal heads 1, two wall formworks 11 and two support members 17, an aluminum alloy short beam 2 is connected between the two early removal heads 1 on one side, the sides of the early removal heads 1 on both sides that are far away from each other are connected to the aluminum alloy main beam 3, and the two corresponding early removal heads 1 in the middle are connected to the aluminum alloy main beam 3, and the bottoms of the plurality of early removal heads 1 are connected to independent support rods 9, and the independent support rods 9 are set to be height-adjustable; A plurality of aluminum alloy short beams 2 located on one side are provided with a same wooden template 4, and a plurality of rigid supports 5 are overlapped under the wooden template 4. The rigid supports 5 are provided, and the rigid supports 5 refer to fixing plates made of FRP material with 16 waist-shaped bolt holes and slightly raised at both ends; A composite plate 6 is provided on the aluminum alloy main beam 3 and the wooden formwork 4, and a plurality of bolts 16 are provided inside the composite plate 6. By setting the aluminum alloy main beam 3 and the aluminum alloy short beam 2, the aluminum alloy main beam 3 and the aluminum alloy short beam 2 are bidirectionally connected through the early disassembly head 1 and fixed with pins; the wooden formwork 4 is used at the cast-in-place position of the floor slab, and the improved aluminum alloy short beam 2 directly contacts with the wooden formwork 4 by reducing the height of the beam body, thereby compensating for the thickness of the wooden formwork 4, ensuring the consistency of the template surface elevation and the overall horizontal force transmission of the rigid beam, and improving the overall rigidity; The bolt 16 penetrates the rigid support 5, and the bottom end of the bolt 16 is threadedly connected with a nut. By setting the rigid support 5 made of FRP material, the bolt 16 hole is reserved through the composite plate 6 to realize hoisting, and the large rigidity is utilized to effectively reduce the downward deflection of the wooden formwork 4 and the aluminum alloy short beam 2; One end of the aluminum alloy main beam 3 is connected to the inner corner formwork 7, the lower part of the inner corner formwork 7 in the middle is connected to the inner beam formwork 8, the bottoms of the two inner beam formworks 8 in the middle are connected to the same beam bottom formwork, and the two corresponding independent support rods 9 in the middle are provided with a horizontal rod 10 under the beam. By setting the horizontal rod 10 under the beam, the horizontal force transmission effect of the rigid beam system is assisted to improve, and the stability and support safety of the entire formwork system are enhanced; the height design of the horizontal rod 10 under the beam is higher than that of the ordinary support rod, so as to avoid the horizontal rod 10 under the beam interfering with the workers walking and working below, and to a certain extent, it can support the cast-in-place structural beam, share the large construction load of the beam body, and further improve the bearing capacity of the supporting structure; The lower part of the inner corner formwork 7 on both sides is connected to the two wall formworks 11, and a plurality of wall back ribs 12 are provided on the side away from the wall formwork 11 and the support 17 on one side, and the same tension screw 15 is connected between the plurality of wall back ribs 12, and the plurality of wall back ribs 12 in the middle are hinged to the top of a plurality of small diagonal braces 13 through pins, and the bottoms of the plurality of small diagonal braces 13 are hinged to a plurality of ground nails 14 through pins, respectively. By arranging the small diagonal braces 13 at the wall corners, it is possible to more effectively prevent the expansion of the mold during concrete pouring; The tension screw 15 is arranged through the wall formwork 11 and the support member 17. By setting the support member 17, the support member 17 can be flexibly set as a wall, a column or a beam according to actual conditions; The horizontal rod 10 under the beam is arranged below the inner formwork 8 of the beam, the horizontal rod 10 under the beam is arranged between two wall formworks 11, the horizontal rod 10 under the beam is arranged between several rigid supports 5 on both sides, and the material of the rigid support 5 is set to FRP material.

[0021] The support structure supports the one-time casting and forming of vertical components, structural beams, composite plates 6 and post-cast strips between plates, which significantly optimizes the construction process; during the one-time casting process, the support structure needs to withstand large horizontal and vertical loads. Through the coordinated work of the bidirectional rigid beams and the independent support rods 9 structure, the formwork system can effectively disperse and transfer the load, avoiding the problem of formwork instability or deformation caused by local stress concentration; and one-time casting can reduce the construction process, avoid the construction joint problem caused by casting in batches, and improve the integrity and strength of the concrete structure; and the formwork joints and support structure stability are also optimized. The joints between the floor slab formwork and the cast-in-place beam formwork and the wall column formwork adopt a combination design of high-precision aluminum alloy formwork and wooden formwork 4, which reduces the joint gap, and sets sealing strips or stop-slurry strips at the joints to prevent leakage of concrete slurry; The support structure adopts a bidirectional rigid beam to transfer the horizontal force of the overall formwork support structure. The upper horizontal load is smoothly transferred to the wall column formwork and then to the ground, so as to realize the horizontal anti-overturning of the formwork support structure and optimize the arrangement of the independent support rods 9. The hanging formwork method rigid support 5 is adopted in the post-casting strip of the composite plate 6 to realize a construction method that fully utilizes the strength of the prefabricated components, and the strength of the composite plate 6 can be utilized in both the formwork erection link and the concrete pouring link. The complex arrangement of the horizontal and vertical rods of the lower support structure is simplified, and the horizontal rod 10 under the beam in the large space below is truly realized. New materials are used to adapt to the rapid construction of prefabricated structures, and the traditional construction system has the disadvantage of serious waste, but the aluminum-wood composite system retains the advantage of flexible adjustment of the traditional wooden formwork 4.

[0022] Working principle and use process of the present invention: S1. Design and preparation before installation: The bidirectional aluminum alloy beam adopts the same standardized size and modular production method as the aluminum alloy formwork, which ensures rapid assembly and efficient turnover during the construction process, and is well adapted to the aluminum alloy formwork construction; usually, the cast-in-place aluminum alloy formwork system is equipped with one set of aluminum alloy formwork, back ribs, etc.; three sets of independent support rods 9 are configured for rapid turnover; the formwork support structure configuration can also achieve rapid turnover and save construction costs; Before starting the installation of the formwork support structure, designers need to establish a clear numbering system in the drawings based on the actual situation of the building bay, mark the specific installation locations, and complete the visual design drawings of the formwork support structure; The design drawings should include: aluminum alloy template number information and layout, aluminum alloy bidirectional rigid beam number information and layout, composite plate 6 opening position; Before formal construction, construction personnel must be fully familiar with the contents of the construction drawings, and clarify the layout of the template and main beam, the assembly sequence, the specific requirements of the connection nodes and the supporting structure; at the same time, they must conduct a comprehensive check of the on-site materials to ensure that the specifications of the main beams are consistent with the design requirements, and carefully check the appearance quality, size and performance of the aluminum alloy beams to ensure that the components are not deformed or damaged; through detailed technical explanations, construction personnel can fully understand the assembly and fixing methods, laying the foundation for ensuring construction quality and efficiency; S2. Wall column formwork installation: The wall column formwork is installed using a single formwork construction method; The construction workers first selected the templates with corresponding numbers according to the markings on the drawings, and systematically assembled the wall and column templates according to the designed positions; then they carefully moved the assembled temporary template structure to the corresponding position where the layout had been completed; To ensure construction safety, a minimum number of pin connections are required to prevent the formwork from falling apart, and temporary supports are provided in a timely manner to prevent the formwork from tipping over during installation, thereby achieving reliable fixation of the formwork; S3, installation of beam formwork and internal angle formwork 7: After completing the installation of the wall column formwork at both ends, the construction personnel start the installation of the aluminum alloy beam formwork in the middle; the construction personnel first reliably connect the single-piece beam bottom formwork with the early dismantling head 1 of the beam bottom on the ground through pins to form a beam bottom formwork as a whole, and then use a two-person cooperation method to install it to the designated position. When the beam is long, an independent support rod 9 can be temporarily supported in the middle of the beam to prevent the formwork from sagging and falling off in the middle of the span; Perform the supplementary installation work of the beam inner template 8 and the wall template 11, and gradually complete the installation of the beam inner template 8, the beam outer template and the wall template 11 in the order of installing the inner wall first and the outer wall later; finally, install the floor slab inner corner template 7 above the beam inner template 8, so as to realize the connection between the beam template and the floor slab template; during the whole operation, a worker passes the aluminum alloy template from the ground to the worker above, and a worker on the ladder carries a small hammer to complete the template pin fixing and installation work; S4, installation of two-way rigid beams: after completing the installation of the internal angle formwork 7, the installation of the two-way aluminum alloy rigid beam system needs to be carried out; the aluminum alloy beams, early dismantling heads 1 and other components should be classified and sorted according to the requirements of the construction drawings, and the short beam components required for the post-casting strip position should be specially identified; The installation process adopts the basic principle of "narrow first and wide later". For the main beam in the narrower direction of the span, the ground pre-assembly process is adopted: the early dismantling head 1 and the aluminum alloy beam are assembled into an integral component on the ground; Then the pre-assembled main beam is lifted into place as a whole, 2-3 people lift the main beam, establish pin connection with both sides of the fixed main beam through the inner corner template 7, and correct its elevation and horizontality in time, and temporarily support the independent support rod 9 at the early dismantling head 1 under the beam; The secondary beams in the wider span direction are installed in a different way: first install the early removal head 1 in place, and then install the aluminum alloy beams one by one on the early removal head 1; this step-by-step installation method can ensure that the connection nodes between the secondary beams and the main beams are accurately aligned, thereby ensuring the stability of the entire supporting structure; The post-casting zone requires special treatment and installation of a special short beam component; the height of this short beam is shorter than that of an ordinary beam by the thickness of a wooden template 4, so that after the wooden template 4 is supported at the post-casting zone, the upper surface of the rigid beam, the wooden template 4 and the lower surface of the composite board 6 are in the same plane; when the laying of the bidirectional rigid beam is completed, the construction personnel need to install an independent support rod 9 directly under each early demolition head 1, and these supports constitute an important foundation of the entire support structure; After the construction is completed, it is necessary to comprehensively check the fastening of the connection nodes and the independent support rods 9, adjust and check the elevation and levelness of the bidirectional rigid beam to ensure that the construction quality meets the requirements of the specifications; S5, connection of the horizontal rod 10 under the beam: For the independent support rods 9 adjacent to both sides of the beam body, the horizontal rod 10 under the beam is used, and a reliable connection is achieved through a special buckle device; it can effectively transfer the horizontal load generated during the construction process and improve the stability of the entire supporting structure; wherein, the horizontal rod 10 under the beam does not contact the lower surface of the beam bottom template and does not bear the vertical load of the beam body; S6, installation of back ribs and small diagonal braces 13: When installing the independent support rods 9, the installation of the wall back ribs 12 needs to be completed simultaneously; different from the traditional practice, this system cancels the setting of large diagonal braces and arranges small diagonal braces 13 at the corners of the wall formwork 11, which effectively prevents the expansion of the formwork that may occur during the concrete pouring process; S7, installation of rigid support 5 and laying of wooden formwork 4: After completing the installation of the main structure of the bidirectional rigid beam, the next step is to start the hoisting process of the composite plate 6; first complete the preliminary preparation work, confirm that the installation of the main structure of the bidirectional rigid beam is completed and check the firmness, then check the specifications and installation position of the composite plate 6, whether there are cracks in the composite plate 6 itself, and check the status of the hoisting equipment and the reliability of the hoisting equipment; At the post-casting strip, it is necessary to prepare a wooden formwork 4 above the aluminum alloy short beam 2, cut the wooden formwork 4 according to the design size, and temporarily fix it with foam glue. Then, the composite plate 6 is hoisted according to the position sequence marked on the construction drawing, and it is safely placed on the aluminum alloy beam to confirm that the gap between the composite plates 6 meets the design requirements; most of the composite plates 6 are placed on the two-way aluminum alloy beam, and the edge part is placed on the laid wooden formwork 4; after the hoisting is completed, the accurate position of the composite plate 6 needs to be adjusted, and the degree of consistency between the reserved channel and the design position needs to be checked; S8, hoisting of the composite plate 6: after the position of the composite plate 6 is adjusted, the worker above the composite plate 6 places bolts 16 everywhere in the reserved holes of the composite plate 6, and the worker below the composite plate 6 installs the rigid support 5 and tightens the bolts 16 to fix it; The post-cast strip is arranged unidirectionally, so the rigid support 5 under the composite plate 6 is also arranged unidirectionally; after the position of the composite plate 6 is adjusted in place, the construction workers on the upper and lower floors cooperate with each other: the workers on the upper floor insert the standard bolts 16 into the reserved holes of the composite plate 6, and check the verticality of the bolts 16 to prevent the subsequent installation difficulties caused by tilting; the construction workers on the ground align the rigid support 5 with the reserved hole position, accurately connect the top of the rigid support 5 with the bolts 16, and adjust the position and direction of the rigid support 5; the direction of the rigid support 5 under the composite plate 6 is perpendicular to the extension direction of the post-cast strip. If the post-cast strip of the composite plate 6 is arranged in two directions, the rigid support 5 is also arranged in two directions; S9. Overall pouring: When the formwork support structure is fully constructed, the concrete pouring operation can begin; the pouring sequence at this stage needs to be strictly operated in accordance with the construction specifications to ensure the quality of concrete pouring; S10, early demolition and turnover; after the concrete strength reaches the early demolition strength requirement, the component demolition work shall be carried out in accordance with the prescribed procedures; the early demolition sequence of the aluminum alloy formwork needs to follow the basic principle of "support first, then demolition, and then demolition", and the aluminum alloy bidirectional rigid beam, aluminum alloy beam formwork, and wall column formwork shall be demolished in turn, and the early demolition head 1, the lower independent support rod 9, the post-casting belt rigid support 5, and the wooden formwork 4 under the floor shall be retained to ensure the safety of the structure; in the process of dismantling the aluminum alloy wall formwork 11, the wall back rib 12 and the small diagonal brace 13 of the wall formwork 11 shall be dismantled simultaneously.

[0023] The removed formwork materials are transferred to the next layer through the reserved material transfer port for the construction and use of the formwork support structure of the next layer; S11. Construction quality inspection: After the concrete strength is fully formed, remove the rigid support 5, wooden formwork 4, early removal head 1 and independent support rod 9 at one time; the rigid support 5 is removed by removing the bolts 16 and nuts under the floor slab, and the bolts 16 remain in the floor slab after pouring. At the same time, remove the wooden formwork 4. After all formwork support components are removed, it is necessary to conduct a comprehensive inspection of the overall construction quality of the concrete, focusing on the forming effect of the concrete surface to ensure that it meets the design requirements and construction specifications.
