Description

Technical Field

[0001] This invention relates to the field of building foundation formwork construction technology, specifically to a large-volume building foundation formwork and construction method. Background Technology

[0002] Building foundation formwork, also known as construction formwork, is a temporary support structure. Fabricated according to design requirements, it shapes concrete structures and components according to specified positions and geometric dimensions, maintains their correct position, and bears the self-weight of the formwork and external loads acting upon it. The purpose of formwork engineering is to ensure the quality and safety of concrete works, accelerate construction progress, and reduce project costs.

[0003] The formwork structure used in the construction of cast-in-place concrete structures mainly consists of three parts: the panel, the supporting structure, and the connectors. The panel is the load-bearing plate that directly contacts the freshly poured concrete; the supporting structure is a temporary structure that supports the panel, the concrete, and the construction load, ensuring that the formwork structure is firmly assembled and does not deform or break; the connectors are the accessories that connect the panel and the supporting structure into a whole.

[0004] Construction formwork refers to the molds and supports used for casting concrete. Based on material properties, it can be categorized into construction formwork, plywood, film-faced plywood, multi-layer plywood, double-sided adhesive-coated formwork, and double-sided film-faced formwork. According to construction process conditions, it can be classified into cast-in-place concrete formwork, pre-assembled formwork, large formwork, and step-up formwork.

[0005] Modular steel formwork is a new type of formwork that "replaces wood with steel" in modern formwork technology. It has the advantages of strong versatility, convenient assembly and disassembly, and high turnover. When used for cast-in-place reinforced concrete structure construction, it can be pre-assembled into large formwork for beams, columns, walls, and floor slabs according to design requirements and hoisted into place as a whole. Alternatively, it can be assembled and disassembled piecemeal.

[0006] In the prior art, the publication number "CN116575709A" discloses a construction method for easy removal of the bottom formwork of a foundation connecting beam. When the method described in this invention is used for construction, the contact surface between the bottom formwork of the independent foundation connecting beam and the bottom formwork of the two sections of foundation connecting beam on both sides is inclined, which makes the formwork removal more convenient and can effectively reduce the formwork removal time. At the same time, the removal process is more labor-saving, avoids damage to the formwork caused by violent removal, increases the repeated service life of the formwork, and helps to save costs.

[0007] However, existing technologies still have significant shortcomings, such as:

[0008] In the above-mentioned device and the prior art:

[0009] 1. Large-volume building formwork is heavy, and when it is fixed by adsorption during lifting and moving, it is prone to shaking, which can lead to problems such as the formwork falling off.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1-8 The present invention provides a technical solution:

[0045] Example 1: A large-volume building foundation template: including an installation base 1, a lifting guide rail 2 and a lifting platform 3. The lifting guide rail 2 is installed on one side of the installation base 1, and the lifting platform 3 is installed on the moving end of the lifting guide rail 2. Electromagnetic slide rails 31 are embedded in the top and bottom of the lifting platform 3, and reciprocating sliders 32 are installed on the moving end of the electromagnetic slide rail 31.

[0046] The bottom of the mounting base 1 is equipped with electric drive casters 11, and the electric drive casters 11 are configured in several groups.

[0047] The building formwork adsorption and movement unit is located on the top of the reciprocating slider 32. It is used to adsorb, pick up and move the building formwork before installation to ensure the vertical and stable installation of the building formwork.

[0048] The building template adsorption and movement unit includes a vertical base 33, on which a first stepper motor 34 is installed. A first movable arm 4 is installed on the rotating end of the first stepper motor 34. The first movable arm 4 is configured as five sets. A storage groove 41 is provided on the surface of the first movable arm 4. A second stepper motor 51 is installed on the other end of the first movable arm 4. A second movable arm 5 is installed on the rotating end of the second stepper motor 51. An electromagnetic chuck 53 is installed on one end of the second movable arm 5. A horizontal locking hole 54 is provided on the surface of the second movable arm 5.

[0049] In this embodiment, when the building template is vertically and stably installed on both sides of the building reinforcement cage, the two sets of building reinforcement cages are locked and installed by the central screw. Before the building foundation template is adsorbed and locked, multiple sets of reciprocating sliders 32 are adjusted by driving the electromagnetic slide rail 31 to unfold. After unfolding, the reciprocating sliders 32 drive the vertical seat 33 to move to the corresponding position. Then, the first stepper motor 34 at the top of the vertical seat 33 drives the first movable arm 4 to flip and move closer to the side of the building foundation template. Then, the second stepper motor 51 readjusts the deflection angle of the second movable arm 5.

[0050] The template adsorption lateral stabilization unit is set in the area of ​​the building template adsorption and movement unit. After the building template is adsorbed and fixed, it needs to be installed on the side of the steel bar. During the installation process, the stability of the template is ensured.

[0051] The template adsorption lateral stabilization unit includes a rotating arm 7. An electric rotating roller 71 is installed on one side of the lifting platform 3. The rotating arm 7 is installed on the rotating end of the electric rotating roller 71. The rotating arm 7 is configured as two sets. A first movable cylinder 77 is installed on each of the two sets of rotating arms 7. A cylindrical insert rod 711 is installed on the movable end of one set of first movable cylinders 77, and a cylindrical insert tube 712 is installed on the movable end of the other set of first movable cylinders 77. A second movable cylinder 72 is embedded in the rotating arm 7. A lateral slider 74 is installed on the movable end of the second movable cylinder 72. A positioning slide rod 73 is installed on one side of the lateral slider 74. One end of the positioning slide rod 73 movably passes through the surface of the rotating arm 7. The cylindrical insert rod 711 and the cylindrical insert tube 712 are movably engaged.

[0052] In this embodiment, the second movable arm 5 drives the electromagnetic chuck 53 to adhere to the side of the building foundation template for adsorption and fixation. After the electromagnetic chuck 53 has finished adsorption and fixation, in order to ensure the stability of the second movable arm 5, the electric rotating roller 71 is driven, so that the electric rotating roller 71 drives the rotating arm 7 to rotate, so that the rotating arm 7 drives the cylindrical insert rod 711 and the cylindrical insert tube 712 to rotate to a state concentric with the transverse locking hole 54. Then, the two sets of first movable cylinders 77 are driven, so that the movable ends of the two sets of first movable cylinders 77 respectively drive the cylindrical insert rod 711 and the cylindrical insert tube 712 to pass through multiple sets of transverse locking holes 54. Then, the cylindrical insert rod 711 and the cylindrical insert tube 712 are fastened together, thereby completing the fixation between the cylindrical insert rod 711 and the cylindrical insert tube 712. At the same time, the fastened cylindrical insert rod 711 and the cylindrical insert tube 712 provide transverse support for multiple sets of second movable arms 5, ensuring stability when the building foundation template is adsorbed, locked and moved.

[0053] The horizontal reinforcement unit for building formwork installation is set on both sides of the lifting platform 3 to lock the lateral position of the building formwork when it is installed vertically.

[0054] The horizontal reinforcement unit for building formwork installation includes a horizontal clamping arm 76, a rotary motor 75 installed on one side of a horizontal slider 74, and the horizontal clamping arm 76 sleeved on the rotating end of the rotary motor 75.

[0055] In this embodiment, when the building foundation template is locked and moved, in order to ensure the lateral fixation of the building template, a rotary motor 75 is driven to rotate the transverse clamping arm 76. When the transverse clamping arm 76 rotates to the side parallel to the building template, the second movable cylinder 72 is driven to move the transverse slider 74 to fit against the side parallel to the building template until the adjacent transverse slider 74 drives the transverse clamping arm 76 to complete the clamping and fixing of both sides of the building template, further ensuring the stability of the building foundation template during adsorption, locking and moving.

[0056] The top of the second movable arm 5 is equipped with a vertical snap-fit ​​unit for the top of the template.

[0057] The template top vertical fastening unit includes a vertical telescopic rod 52, an extension arm 6 is installed on the movable end of the vertical telescopic rod 52, a sealing block 63 is slidably installed through the surface of the extension arm 6, a horizontal frame 61 is installed on the top of the extension arm 6, a drive gear 62 is installed between adjacent horizontal frames 61, a groove 64 is provided on the side of the sealing block 63 near the drive gear 62, a straight toothed plate 65 is installed inside the groove 64, and the drive gear 62 meshes with the straight toothed plate 65 for transmission.

[0058] The sealing block 63 is provided with an anti-slip pad 66 on the side near the transverse frame 61.

[0059] In this embodiment, before vertically inserting the building foundation formwork into the side of the building reinforcement cage for vertical installation, the extension arm 6 is driven to descend vertically by the vertical telescopic rod 52. When the extension arm 6 descends to fit against the top of the building foundation formwork, the drive gear 62 is driven to rotate. The drive gear 62 meshes and drives the linear toothed plate 65 to move. As the linear toothed plate 65 moves downward step by step, the sealing block 63 will continuously protrude through the extension arm 6, and the anti-slip pad 66 on one side of the sealing block 63 will gradually fit against the top side of the building foundation formwork, thereby applying pressure to the top of the building foundation formwork, making the building foundation formwork stable during vertical installation, and further ensuring the vertical and stable installation of the building formwork.

[0060] Example 2:

[0061] Based on Embodiment 1, this embodiment considers that by adding a cylindrical insert rod 711 and a cylindrical insert tube 712 that can be laterally perforated in the region of the second movable arm 5, the structural rigidity of the region of the second movable arm 5 is improved. However, the region of the first movable arm 4 is also set to multiple groups. In order to improve the structural rigidity and structural stability of the region of the first movable arm 4, this embodiment 2 is provided with a movable arm lateral fastening locking unit to improve the structural rigidity of the region of the first movable arm 4.

[0062] The storage slot 41 is provided with a movable arm lateral fastening and locking unit. The movable arm lateral fastening and locking unit includes a deflection block 43. The first movable arm 4 is set into five groups. The five groups of first movable arms 4 are sequentially mounted with drive rollers 42. The deflection block 43 is mounted on the rotating end of the drive roller 42. Each group of deflection blocks 43 is provided with a mounting hole 44 and a plug 45 on its surface. Adjacent deflection blocks 43 are fixed by the plug 45 and the mounting hole 44.

[0063] In this embodiment, the first movable arm 4 is configured as five groups. The drive rollers 42 in the storage grooves 41 inside the five groups of first movable arms 4 are non-concentrically installed so that the five groups of deflection blocks 43 can be connected end to end in sequence. The bottom of the previous group of deflection blocks 43 can be attached to the top of the next group of deflection blocks 43 and locked by the mounting holes 44 and the inserts 45, thereby completing the integrated locking support of the five groups of first movable arms 4, thereby improving the structural rigidity of the area of ​​the first movable arm 4.

[0064] A construction method, based on the aforementioned large-volume building foundation formwork, includes the following steps:

[0065] S1: Drive the electric caster 11 to move the installation base 1 to the building steel cage installation area. At this time, drive the lifting guide rail 2 to make the lifting platform 3 drive the building foundation formwork to be vertically inserted into the side of the building steel cage for vertical installation, thereby ensuring the vertical and stable installation of the building formwork.

[0066] S2: The cylindrical rod 711 and the cylindrical tube 712 pass through multiple sets of transverse locking holes 54, and then the cylindrical rod 711 and the cylindrical tube 712 are fastened together, thereby completing the fixation between the cylindrical rod 711 and the cylindrical tube 712. At the same time, the fastened cylindrical rod 711 and the cylindrical tube 712 provide transverse support for multiple sets of second movable arms 5 to ensure stability when the building foundation template is adsorbed, locked and moved.

[0067] S3: The second movable cylinder 72 drives the horizontal slider 74 to move to fit against the side of the parallel building template until the adjacent horizontal slider 74 drives the horizontal clamping arm 76 to complete the clamping and fixing of both sides of the building template, further ensuring the stability of the building foundation template when it is adsorbed, locked and moved.

[0068] S4: The anti-slip pad 66 on one side of the sealing block 63 will gradually adhere to the top side of the building foundation formwork, thereby applying pressure to the top of the building foundation formwork, making the building foundation formwork stable during vertical installation, and further ensuring the vertical and stable installation of the building formwork.

[0069] Working principle: During use, the operator moves the installation base 1 by driving the electric casters 11. When the installation base 1 moves to the building foundation formwork area, the lifting platform 3 is lowered by driving the lifting guide rail 2. After the lifting platform 3 is lowered into place, the operator uses the electromagnetic chuck 53 to attach and fix the building foundation formwork. Then, the operator drives the lifting guide rail 2 again to raise the building foundation formwork. Then, the electric casters 11 are driven to move the installation base 1 to the building rebar cage installation area. At this time, the lifting platform 3 is driven by driving the lifting guide rail 2 to vertically insert the building foundation formwork into the side of the building rebar cage for vertical installation, thereby ensuring the vertical and stable installation of the building formwork.

[0070] When the building formwork is vertically and stably installed on both sides of the building reinforcement cage, the two sets of building reinforcement cages are locked and installed by the central screw. Before the building foundation formwork is attracted and locked, multiple sets of reciprocating sliders 32 are adjusted by driving the electromagnetic slide rail 31 to unfold. After unfolding, the reciprocating sliders 32 drive the vertical seat 33 to move to the corresponding position. Then, the rotating end of the first stepper motor 34 at the top of the vertical seat 33 drives the first movable arm 4 to flip and move closer to the side of the building foundation formwork. Then, the second stepper motor 51 readjusts the deflection angle of the second movable arm 5. After the adjustment is completed, the second movable arm 5 drives the electromagnetic chuck 53 to adhere to the side of the building foundation formwork for attraction and fixation. After the electromagnetic chuck 53 is attracted and fixed, in order to ensure The stabilization of the second movable arm 5 drives the electric rotating roller 71, which in turn drives the rotating arm 7 to rotate. This causes the rotating arm 7 to rotate the cylindrical insert rod 711 and the cylindrical insert tube 712 to a concentric state with the transverse locking hole 54. Subsequently, it drives two sets of first movable cylinders 77, causing the movable ends of the two sets of first movable cylinders 77 to drive the cylindrical insert rod 711 and the cylindrical insert tube 712 through multiple sets of transverse locking holes 54. Then, the cylindrical insert rod 711 and the cylindrical insert tube 712 are fastened together, thus completing the fixation between the cylindrical insert rod 711 and the cylindrical insert tube 712. At the same time, the fastened cylindrical insert rod 711 and the cylindrical insert tube 712 provide transverse support for multiple sets of second movable arms 5, ensuring stability when the building foundation template is adsorbed, locked, and moved.

[0071] When the building foundation formwork is locked and moved, in order to ensure the lateral fixation of the building formwork, a rotary motor 75 is driven to rotate the horizontal clamping arm 76. When the horizontal clamping arm 76 rotates to the side parallel to the building formwork, the second movable cylinder 72 is driven to move the horizontal slider 74 to fit against the side parallel to the building formwork until the adjacent horizontal slider 74 drives the horizontal clamping arm 76 to complete the clamping and fixing of both sides of the building formwork, further ensuring the stability of the building foundation formwork during adsorption, locking and moving.

[0072] Before vertically inserting the building foundation formwork into the side of the building reinforcement cage for vertical installation, the extension arm 6 is driven to descend vertically by the vertical telescopic rod 52. When the extension arm 6 descends to fit against the top of the building foundation formwork, the drive gear 62 is driven to rotate. The drive gear 62 meshes and drives the linear toothed plate 65 to move. As the linear toothed plate 65 moves downward step by step, the sealing block 63 will continuously protrude through the extension arm 6. The anti-slip pad 66 on one side of the sealing block 63 will gradually fit against the top side of the building foundation formwork, thereby applying pressure to the top of the building foundation formwork, making the building foundation formwork stable during vertical installation, and further ensuring the vertical and stable installation of the building formwork.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
