[0002] At present, in the construction industry, casting formwork is used to shape concrete structures and components according to the specified position and geometric dimensions in engineering construction, so as to maintain their correct position. The materials of casting formwork used in my country's construction industry are wood, bamboo, plastic, steel, and aluminum castings. When pouring concrete, it is necessary to build the formwork used for pouring. The existing wood and bamboo formworks are mainly fixed by on-site carpentry. The installation period is long and the construction workers are required to have high proficiency. Generally, they are skilled workers, and the project is time-consuming and the labor cost is high. Moreover, after the cement hardens in the later stage, it is also time-consuming to disassemble. The formwork can only be reused a few times before it is scrapped.

[0003] However, the existing plastic, steel and aluminum casting template structures are relatively bulky, difficult to install and complex to disassemble due to their design characteristics, and require a lot of manpower, which is not conducive to the rapid advancement of the project.

[0004] In the process of disassembling the existing building formwork, both ends are fixed, so both ends need to be disassembled for demoulding; in the process of disassembling both ends, the formwork is likely to fall from a high altitude (generally 2.7-5 meters), which is prone to personnel safety accidents, and the formwork is easily damaged during the free fall from the high altitude, causing deformation or damage, affecting the use; and generally, at least two people are required to cooperate in demoulding during the disassembly process.

[0005] The following prior art was found through search:

[0006] Patent 1: Chinese patent application number: 202120448683.2 Application date: 2021-03-02, Patent name: A telescopic formwork keel connector. The utility model discloses a telescopic formwork keel connector, comprising an external formwork keel and an internal formwork keel, the internal formwork keel is detachably slidably penetrated in the inner cavity of the external formwork keel, characterized in that: at least one of the two ends of the external formwork keel is in an open form, and both ends of the internal formwork keel are in a closed form; when working, the internal formwork keel slides into or out of the inner cavity of the external formwork keel along the open end of the external formwork keel to achieve telescopic adjustment of the length of the entire formwork keel connector. The advantages of the utility model are: simple structure, easy installation and disassembly, wide range of use, strong practicality, and can well solve the problem of rising cost of formwork keel use caused by size changes of building surfaces on different floors or in different areas during on-site construction.

[0007] It mainly solves the telescopic problem and is a general technical reference material. It has no substantial technical contribution to the present invention and does not have any technical enlightenment effect.

[0008] Patent 2: Chinese patent application number: 201921034796.7 Application date: 2019-07-04, Patent name: A floor keel bracket for building formwork, the utility model discloses a floor keel bracket for building formwork, including a keel body, a bracket, a support rod, a first support edge and a second support edge, the keel body is in an inverted U shape, the bracket is inserted into the keel body from bottom to top, the upper end of the support rod abuts against the bracket to play a supporting role, and the first support edge and the second support edge are respectively detachably fixed horizontally on both sides of the lower edge of the keel body. Compared with the prior art, the utility model is a floor keel bracket for building formwork, which uses a support rod and a bracket to support the keel body, and uses the first support edge and the second support edge to support the aluminum formwork. After the pouring is completed, the first support edge and the second support edge can be removed, and the aluminum formwork can be removed, while the keel body still exists in the structure, thereby effectively improving the structural strength of the floor slab.

[0009] It discloses a floor keel bracket structure, which has a different structure and technical effects. It is a general technical reference material and has no substantial technical contribution to the present invention and no technical enlightenment effect.

[0010] Patent 3: Chinese patent application number: 201110163774.2 Application date: 2011-06-17, Patent name: An early dismantling formwork system and its construction method, the present invention relates to an early dismantling formwork system and its construction method, the early dismantling formwork system comprises an early dismantling formwork and a supporting mechanism, the early dismantling formwork comprises a facade formwork, a top formwork, and a transition formwork, the supporting mechanism comprises a joist supporting the top formwork, an adjustable supporting rod, and a positioning locking mechanism for adjusting the height of the joist position; the positioning locking mechanism is connected to the end of the joist, and the joist is supported by the adjustable supporting rod. The construction method of the early dismantling formwork system, the installation method thereof comprises: erecting the facade formwork and transition formwork of the wall and column; erecting the supporting mechanism and the joist; laying the top formwork on the joist. The disassembly method comprises: dismantling the facade formwork; lowering the height of the joist; making the top formwork separate from the cast concrete slab and fall on the joist; removing the top formwork to dismantle the joist and transition formwork; and dismantling the adjustable supporting rod.

[0016] The present invention proposes a brand-new structure and disassembly and assembly method: it comprises a building template keel structure, a template adopting the structure, and a disassembly and assembly method thereof; after adopting the present invention, the construction and installation are simple, convenient and fast, and the disassembly is also convenient; the template will not fall off freely, which protects the template and enhances the safety of the project; the demolding of the group unit can be completed independently without the cooperation of multiple people, which greatly improves the project efficiency, saves time, saves a lot of manpower and material resources, and has good project quality. Summary of the invention

[0017] The purpose of the present invention is to provide a building template keel structure and a template using the structure and a disassembly and assembly method thereof, which are simple, convenient and quick to construct and install, and are also convenient to disassemble. The template will not fall off freely, which protects the template and enhances the safety of the project. It also greatly improves the project efficiency, saves time, saves a lot of manpower and material resources, and has good project quality.

[0018] To achieve the above-mentioned object, the present invention proposes the following technical solution: a building template keel structure, comprising: a keel seat of a metal structure, and a hook plate arranged below the keel seat, wherein the hook plate is a symmetrical structure and is vertically fixed below the keel seat, and both ends of the hook plate are upwardly tilted to form a hook-shaped structure;

[0019] The two sides of the keel seat are respectively provided with side plates for connection;

[0020] The keel seat is a long strip structure with a U-shaped cross section, and its opening is downward; the hook plate is vertically welded in the U-shaped groove;

[0021] At least one hook plate is arranged on the keel seat.

[0022] Furthermore, two hook plates are provided on the keel and are symmetrically arranged in the middle position of the keel seat.

[0023] Furthermore, the hook plate includes a long bottom plate, hooks formed by bending upwards at both ends of the bottom plate, and connecting plates formed by bending upwards on both sides of the middle of the bottom plate.

[0024] Furthermore, the connecting plate is fixedly welded in the U-shaped groove of the keel seat, and is fixedly connected to the inner bottom of the keel seat and the two side surfaces of the U-shaped groove; the lower end of the connecting plate is longer than the groove edge height of the U-shaped groove; a gap is left between the bottom plate of the hook plate and the bottom of the keel seat.

[0025] Furthermore, a latch box is provided in the U-shaped groove of the keel seat, and the box body structure of the latch box is a U-shaped plate with a bottom opening, and the box body is encapsulated in the U-shaped groove to form a sealing structure; a latch that can move freely along the bottom opening is inserted therein.

[0026] Furthermore, a reinforcing sheet of the same size as the bottom projection is welded to the bottom surface of the latch box, an opening is provided on the reinforcing sheet corresponding to the box body, and the latch is inserted into the reinforcing sheet and the bottom opening of the box body; the upper end of the latch is provided as a plug so that it cannot leak out of the bottom opening; the latch can be sheet-shaped or columnar.

[0027] The present invention discloses another technical solution: a template with a keel structure, using the above-mentioned building template keel structure as a template connection seat; it also includes:

[0028] A first jacking support connected to both ends of the keel structure, and a support screw, a support nut, and a support sleeve connected in sequence below the jacking support;

[0029] A second keel for supporting the template below, a second top bracket connected to both ends of the second keel, and a support screw, a support nut, and a support sleeve connected in sequence below the top bracket;

[0030] The second keel and the supporting structure assembly can be arranged in multiple groups along the length direction of the template;

[0031] The template is hung on the hook of the hook plate of the keel seat through the template head arranged at the front end thereof, and the template is supported by the second keel;

[0032] The template head of the template is a semi-closed folding structure in cross section, which is bent downward and then horizontally bent inward to form a first folding edge, then vertically bent upward to form a second folding edge, and then bent vertically outward to form a third folding edge.

[0033] Furthermore, a template head is also provided at the other end of the template; a keel seat is provided at the other end of the corresponding template, which is connected to the first top support at both ends of the keel structure; and 0 to multiple groups of second keels and supporting structure groups are optionally provided in the middle of the template depending on the length of the template.

[0034] Furthermore, the templates installed on the keel seat are two templates symmetrically arranged on the left and right, and side supports for supporting the cover plate are arranged on the outer sides of the templates.

[0035] The present invention discloses a third technical solution: a method for disassembling and assembling a template with a keel structure, which is used for disassembling and assembling the template with a keel structure;

[0036] During installation: insert the template head of the template into the hook plate of the keel seat, and ensure that the hook head is blocked on the outside of the second folded edge of the template head; and connect the locking structure with the pin dropped from the pin box to fix the keel seat and template connected in pairs;

[0037] When disassembling: After the concrete above solidifies, remove the locking structure of the latch box at one end of the template, and the template falls down a certain distance H;

[0038] Then remove the other end of the template and make sure that the end of the template with the template head is hung on the hook. In this way, the template will be rotated 90 degrees vertically under the action of gravity, and finally the hook will block the outside of the third fold of the template, and the template will drop from the horizontal position to the vertical position;

[0039] Finally, lift the template upwards, let the template head slide over the hook head and remove the template, and the template disassembly is completed.

[0040] Beneficial effects: The present invention provides a building template keel structure, a template using the structure, and a disassembly and assembly method thereof; after adopting the present invention, the construction and installation are simple, convenient and quick, and the disassembly is also convenient. The template will not fall off freely, which protects the template and enhances the safety of the project; the demolding of the group unit can be completed independently without the cooperation of multiple people, which greatly improves the project efficiency, saves time, saves a lot of manpower and material resources, and has good project quality.

[0041] The invention discloses a keel structure of a building template, which particularly adopts a U-shaped groove structure, thereby reducing the weight of the keel while ensuring the support of the keel; the U-shaped groove is convenient for sealing to form a latch box structure, in which a latch that can move freely along an opening is arranged; when the structure is inverted and stored, the latch falls back into the latch box, does not occupy space and is convenient for carrying; when the structure is needed, the latch automatically falls down under the action of gravity, is convenient for fixed installation with other structures, and is convenient and practical.

[0042] The special design of the hook plate facilitates the fixing and removal of the formwork; and the hook plate is specially designed so that the lower end of the connecting plate is longer than the height of the edge of the U-shaped groove, so that there is a gap between the bottom plate of the hook plate and the bottom of the keel seat. This ensures that the template head of the connected formwork can leave a movable gap between the hook plate and the concrete poured above, which is convenient for rotation and removal operations.

[0043] The template of the present invention adopts this structure, and its specially designed template head is a folding structure with a semi-closed cross-section. Its multiple folds form a G-shaped folding structure, and each fold is perpendicular to each other; the fold is integrally hung on the inner side of the hook head of the hook plate and can only be rotated 90 degrees upward and downward on the hook plate. Due to the existence of the hook head and the docking with the folded edge, a hanging is formed and it will not fall off, which ensures construction safety while facilitating disassembly.

[0044] The present invention adopts the template disassembly and assembly method with the keel structure. After the concrete above is solidified, the locking structure of the latch box at one end of the template is disassembled, and the template falls off a certain distance H downward; then the other end of the template is disassembled, and it is ensured that the end of the template with the template head is hung on the hook head, so that the template will be vertically rotated 90 degrees under the action of gravity, and finally the hook head blocks the outside of the third folded edge of the template, and the template is lowered from the horizontal position to the vertical position; finally, the template is lifted up, and the template head is allowed to slide over the hook head and then the template is removed, and the disassembly of the template is completed.

[0045] This method requires only one-person operation, which completely changes the previous method in which the template needed the cooperation of multiple people to disassemble and the template was exposed to gravity during the disassembly process. After loosening a locking connection, the template is rotated 90 degrees and hung on the keel seat, ensuring construction safety and protecting the template from falling, avoiding damage to itself due to falling gravity.

[0090] The invention discloses a keel structure of a building template, which particularly adopts a U-shaped groove structure, thereby reducing the weight of the keel while ensuring the support of the keel; the U-shaped groove is convenient for sealing to form a latch box structure, in which a latch that can move freely along an opening is arranged; when the structure is inverted and stored, the latch falls back into the latch box, does not occupy space and is convenient for carrying; when the structure is needed, the latch automatically falls down under the action of gravity, is convenient for fixed installation with other structures, and is convenient and practical.

[0091] The special design of the hook plate facilitates the fixing and removal of the formwork; and the hook plate is specially designed so that the lower end of the connecting plate is longer than the height of the edge of the U-shaped groove, so that there is a gap between the bottom plate of the hook plate and the bottom of the keel seat. This ensures that the template head of the connected formwork can leave a movable gap between the hook plate and the concrete poured above, which is convenient for rotation and removal operations.

[0092] The template of the present invention adopts this structure, and its specially designed template head is a folding structure with a semi-closed cross-section. Its multiple folds form a G-shaped folding structure, and each fold is perpendicular to each other; the fold is integrally hung on the inner side of the hook head of the hook plate and can only be rotated 90 degrees upward and downward on the hook plate. Due to the existence of the hook head and the docking with the folded edge, a hanging is formed and it will not fall off, which ensures construction safety while facilitating disassembly.

[0093] The present invention adopts the template disassembly and assembly method with the keel structure. After the concrete above is solidified, the locking structure of the latch box at one end of the template is disassembled, and the template falls off a certain distance H downward; then the other end of the template is disassembled, and it is ensured that the end of the template with the template head is hung on the hook head, so that the template will be vertically rotated 90 degrees under the action of gravity, and finally the hook head blocks the outside of the third folded edge of the template, and the template is lowered from the horizontal position to the vertical position; finally, the template is lifted up, and the template head is allowed to slide over the hook head and then the template is removed, and the disassembly of the template is completed.

[0094] This method requires only one-person operation, which completely changes the previous method in which the template needed the cooperation of multiple people to disassemble and the template was exposed to gravity during the disassembly process. After loosening a locking connection, the template is rotated 90 degrees and hung on the keel seat, ensuring construction safety and protecting the template from falling, avoiding damage to itself due to falling gravity.
