Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, and in particular to a set of tools and casting process for synchronous casting of embedded parts. Background Technology

[0002] In the field of construction engineering, especially in various installation projects, embedded parts are the core components of reserved connection nodes. Their installation quality directly determines the stability of subsequent equipment installation, the overall structural stress performance, and the safety of engineering use. They are widely used in many construction scenarios that require pre-set connection carriers, such as industrial plant equipment foundations, building curtain wall fixing, and bridge structure connection.

[0003] Currently, the mainstream methods for constructing embedded parts in the industry are mainly divided into two categories: pre-installed embedded parts and post-installed embedded parts. Pre-installed embedded parts are the traditional and widely used method. The core operation involves fixing the embedded parts to the internal steel reinforcement framework of the structure using methods such as wire binding and welding. Alternatively, in areas without reinforcement, steel supports are erected separately, and the embedded parts are welded to the supports. The positioning and fixation of the embedded parts are achieved through the support force of the steel reinforcement framework or supports. This method can adapt to the simultaneous progress of structural construction and can meet the foundation embedded needs of different reinforcement configurations. Post-installed embedded parts are implemented after the concrete structure has formed. The process typically involves drilling holes in the hardened concrete structure, cleaning the dust from the holes, injecting special chemical adhesive, and then inserting anchor bolts into the holes. After the chemical adhesive cures, a strong bonding system is formed, thereby fixing the embedded parts to the concrete structure. This method is often used in construction scenarios where embedded parts were not pre-installed or where the pre-installed position needs to be corrected.

[0004] However, the existing technology still has the following drawbacks: the construction of pre-installed embedded parts requires the separate construction of binding nodes or the erection of independent supports for each embedded part, and the fixing of each embedded part requires separate measurement, positioning and reinforcement, lacking a unified batch fixing support system; the construction of post-installed embedded parts also requires separate operation of drilling, gluing, and bolting for each embedded part. Both methods can only be carried out around a single embedded part, and cannot adapt to the synchronous positioning and fixing requirements of embedded parts in groups, resulting in low construction efficiency and difficulty in meeting the requirements of large-scale, high-precision batch embedded construction. Summary of the Invention

[0005] This application provides a set of tools and casting process for synchronous casting of embedded parts, which solves the problem that the existing technology cannot adapt to the synchronous positioning and fixing requirements of embedded parts in batches or groups, resulting in low construction efficiency and difficulty in meeting the requirements of large-scale, high-precision batch embedded construction.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a supporting tool for synchronous casting of embedded parts, comprising a combined steel template, wherein multiple combined steel templates are provided, and a horizontal support frame is installed on the top of each combined steel template. Each horizontal support frame has at least two through holes, and an embedded part is installed at the through hole. The upper surface of the embedded part is provided with two external threaded connecting rods. The two external threaded connecting rods pass through the through holes of the horizontal support frame and are respectively fitted with a lower limit nut and an upper limit nut. The upper limit nut abuts against the upper part of the horizontal support frame, and the lower limit nut abuts against the lower part of the horizontal support frame. Adjacent and collinear horizontal support frames are fixedly connected by a horizontal connecting frame, and the positions of each horizontal support frame near both ends can be fixed to the edge of the combined steel template.

[0007] Because this device uses multiple combined steel templates, each of which has at least two through holes for embedded parts, a horizontal support frame is installed above it. Two externally threaded connecting rods on the upper surface of the embedded parts pass through the through holes and are fixed to the horizontal support frame via lower and upper limit nuts. Adjacent collinear horizontal support frames are fixedly connected via horizontal connecting frames, and the horizontal support frames near their ends can be fixed to the edges of the combined steel templates. Therefore, when using this device, multiple combined steel templates can be spliced ​​together to form a pouring surface. Then, multiple embedded parts are installed simultaneously through the through holes of the horizontal support frames. The lower and upper limit nuts are used to precisely adjust and fix the height and verticality of the embedded parts. Simultaneously, the horizontal connecting frames connect the horizontal support frames into a whole, forming a unified batch fixing support system in conjunction with the fixing of the horizontal support frames and the combined steel templates. This achieves synchronous positioning and fixing of embedded parts in sections and groups, thus solving the problem in existing technologies where the synchronous positioning and fixing of embedded parts in sections and groups is not feasible, resulting in low construction efficiency and difficulty in meeting the requirements of large-scale, high-precision batch pre-embedded construction.

[0008] As a further improvement to the above solution, the transverse support frame is fixed to the edge of the combined steel formwork near both ends by a clamping mechanism. The clamping mechanism includes a step-by-step tightening buckle and a clamping plate located above the step-by-step tightening buckle. One side of the clamping plate is clamped and fixed to the bottom of the transverse support frame, and the other side of the clamping plate is provided with a stud running vertically through it. The lower end of the stud passes through the pressure plate of the step-by-step tightening buckle and abuts against the upper plane of the edge of the combined steel formwork. The latch of the step-by-step tightening buckle is pressed against the lower plane of the edge of the combined steel formwork. Thus, during assembly, construction personnel can quickly complete the positioning and fixing of the transverse support frame and the combined steel formwork. During disassembly, only the stud and the step-by-step tightening buckle need to be loosened to separate the two, which greatly reduces the difficulty of operation and construction time.

[0009] As a further improvement to the above solution, the clamping plate is provided with a slot for engaging with the bottom of the transverse support frame. The upper edge of one side of the slot extends inward to form a flange, and a rubber pad is provided on the inner wall of the other side of the slot. The flange can abut against the upper surface of the transverse support frame to form a limit, effectively preventing the clamping plate from slipping off the transverse support frame during assembly operations or concrete pouring vibration. At the same time, the rubber pad will undergo elastic deformation with the engaging action, which not only fills the small gap between the slot and the transverse support frame, increases the friction between the two, improves the tightness of the clamping connection, but also buffers the impact of pouring vibration on the connection structure.

[0010] As a further improvement to the above solution, two relatively parallel transverse support frames are connected by a longitudinal support mechanism. The longitudinal support mechanism includes a longitudinal support frame and a longitudinal connecting frame. The longitudinal support frame is vertically and fixedly connected to the transverse support frame, and the two ends of the longitudinal connecting frame are respectively fixedly connected to the close ends of the two longitudinal support frames. This significantly improves the overall rigidity and structural stability of the entire tool set, effectively resisting the lateral pressure generated during concrete pouring and the vibration impact caused by vibration operation, avoiding deformation or displacement of the support system, and thus ensuring that the positioning accuracy of the pre-embedded parts in sections and groups is not damaged.

[0011] As a further improvement to the above solution, the end of the longitudinal support frame is inserted into the interior of the longitudinal connecting frame, and a tightening bolt is installed on the side wall of the longitudinal connecting frame. One end of the tightening bolt passes through the interior of the longitudinal connecting frame and presses the end of the longitudinal support frame. Thus, during assembly, the end of the longitudinal support frame can be directly inserted into the longitudinal connecting frame, and the insertion depth can be flexibly adjusted according to the actual spacing at the construction site. There is no need to customize components for different construction scenarios, which improves the adaptability of the longitudinal support mechanism.

[0012] As a further improvement to the above solution, the inner wall of the longitudinal connecting frame is provided with a protrusion extending along its own length direction, and the side wall of the longitudinal support frame is provided with a groove extending along its own length direction. The groove of the longitudinal support frame and the protrusion of the longitudinal connecting frame are adapted to engage.

[0013] As a further improvement to the above solution, a right-angle reinforcing member is provided at the connection between the longitudinal support frame and the transverse support frame. The two right-angled sides of the right-angle reinforcing member are fixedly connected to the longitudinal support frame and the transverse support frame, respectively. This can effectively enhance the structural strength and rigidity of the connection between the two, disperse the force concentrated at the connection during concrete pouring and vibration operations, and avoid deformation, loosening or even damage at the connection due to excessive local stress.

[0014] As a further improvement to the above solution, the edge of the outermost combined steel formwork is fixed to one end of the corresponding transverse support frame by a positioning and clamping mechanism. The positioning and clamping mechanism includes a C-shaped frame and a threaded rod. The threaded rod is threaded to the upper end of the C-shaped frame, and a lower clamping nut and an upper clamping nut are fitted to the outside of the threaded rod. The upper end of the threaded rod is provided with a T-shaped knob, and the lower end of the threaded rod is provided with an upper clamp. The lower end of the positioning and clamping mechanism is provided with a lower clamp. The lower clamp is located at the bottom of the edge of the combined steel formwork, and the upper clamp is located above the edge of the combined steel formwork. The lower clamping nut abuts against the bottom of the transverse support frame, and the upper clamping nut abuts against the top of the transverse support frame. Thus, when this device is in use, the threaded rod can be moved down by turning the T-shaped knob, so that the upper and lower clamps clamp the edge of the combined steel formwork. At the same time, the transverse support frame is locked by the upper and lower clamping nuts, forming a double clamping and fixing structure. This achieves precise positioning of the outermost transverse support frame and the combined steel formwork, and also provides reliable lateral constraint.

[0015] This invention also discloses a process for synchronous casting of embedded parts, which uses the aforementioned tools for synchronous casting of embedded parts, and is characterized by including the following steps: Step 1: Determine the distribution location and quantity of embedded parts and the assembly range of combined steel formwork according to the construction drawings. Assemble multiple combined steel formworks to form a pouring surface. Adjust the position and level of the combined steel formwork to meet the requirements of the construction specifications. Step 2: Place the horizontal support frames one by one on top of the combined steel formwork. Determine the position of each horizontal support frame by measuring and laying out the lines. Insert the upper threaded part of the embedded part through the through hole of the corresponding horizontal support frame, tighten the lower limit nut and upper limit nut, and precisely adjust the height and verticality of the embedded part before locking it in place. Connect and fix adjacent collinear horizontal support frames with horizontal connecting frames, and connect relatively parallel horizontal support frames through the longitudinal support mechanism to form an overall support system. Fix both ends of each horizontal support frame to the edge of the combined steel formwork through the clamping mechanism, and fix the outermost combined steel formwork and the horizontal support frame through the positioning and clamping mechanism to complete the fixing of the entire device. Step 3: After checking and confirming the position, height, verticality and overall stability of all embedded parts, continuously pour concrete into the combined steel formwork. During the pouring process, avoid direct impact on the embedded parts and support system, and at the same time carry out concrete vibration operation. Step 4: After the concrete has cured to the design strength, remove the positioning clamping mechanism, clamping mechanism, longitudinal connecting frame, longitudinal support frame and transverse connecting frame in sequence. Then tighten the upper limit nut and lower limit nut to separate the transverse support frame from the embedded parts, and complete the removal of the formwork and fixing device.

[0016] As can be seen from the above technical solutions, the present invention has at least the following technical effects or advantages: Because this device uses multiple combined steel templates, each of which has at least two through holes for embedded parts, a horizontal support frame is installed above it. Two externally threaded connecting rods on the upper surface of the embedded parts pass through the through holes and are fixed to the horizontal support frame via lower and upper limit nuts. Adjacent collinear horizontal support frames are fixedly connected via horizontal connecting frames, and the horizontal support frames near their ends can be fixed to the edges of the combined steel templates. Therefore, when using this device, multiple combined steel templates can be spliced ​​together to form a pouring surface. Then, multiple embedded parts are installed simultaneously through the through holes of the horizontal support frames. The lower and upper limit nuts are used to precisely adjust and fix the height and verticality of the embedded parts. Simultaneously, the horizontal connecting frames connect the horizontal support frames into a whole, forming a unified batch fixing support system in conjunction with the fixing of the horizontal support frames and the combined steel templates. This achieves synchronous positioning and fixing of embedded parts in sections and groups, thus solving the problem in existing technologies where the synchronous positioning and fixing of embedded parts in sections and groups is not feasible, resulting in low construction efficiency and difficulty in meeting the requirements of large-scale, high-precision batch pre-embedded construction.

[0019] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0020] This invention discloses a set of tools for synchronous casting of embedded parts, such as... Figure 1 , Figure 2 , Figure 6 As shown, it includes a combined steel formwork 1, of which multiple combined steel formwork 1s are provided. Each combined steel formwork 1 is equipped with a horizontal support frame 2. Each horizontal support frame 2 is provided with at least two through holes for embedded parts 0 to pass through. The two threaded portions at the upper end of the embedded parts 0 pass through the through holes of the horizontal support frame 2 and are fixed by a lower limit nut 3 and an upper limit nut 4. The upper limit nut 4 abuts against the upper part of the horizontal support frame 2, and the lower limit nut 3 abuts against the lower part of the horizontal support frame 2. Adjacent and collinear horizontal support frames 2 are fixedly connected by a horizontal connecting frame 5. The positions of each horizontal support frame 2 near both ends can be fixed to the edge of the combined steel formwork 1 by a clamping mechanism 6.

[0021] In this embodiment, the combined steel formwork 1 is assembled into a suitable construction formwork system according to the distribution range of the embedded parts 0 required for construction. The number of these formsworks can be flexibly adjusted according to the actual construction area. Multiple combined steel formworks 1 are spliced ​​together to form a continuous pouring surface. The transverse support frame 2 is made of steel profiles and has a long strip structure. Its length is adapted to the width of the corresponding combined steel formwork 1 so as to be stably erected above the combined steel formwork 1. Each transverse support frame 2 has at least two through holes spaced apart along its length. The diameter of the through holes is slightly larger than the outer diameter of the threaded part at the upper end of the embedded part 0 to ensure that the embedded part 0 can pass through smoothly. The embedded part 0 is a threaded columnar component with two externally threaded connecting rods 25 on its upper surface, which are used to engage with the lower limit nut 3 and the upper limit nut 4, respectively. After the embedded part 0 passes through the through hole of the transverse support frame 2, the lower limit nut 3 is first screwed on the threaded part below the transverse support frame 2 to make it tightly abut against the lower surface of the transverse support frame 2. Then, the upper limit nut 4 is screwed on the threaded part above the transverse support frame 2 to make it tightly abut against the upper surface of the transverse support frame 2. The embedded part 0 is fixed to the transverse support frame 2 by the clamping action of the upper and lower nuts. Adjacent transverse support frames 2 that are on the same straight line are fixed by transverse connecting frames 5. The two ends of the transverse connecting frames 5 are fixed to the ends of the two transverse support frames 2, forming a transverse integral support system. Each transverse support frame 2 is equipped with a clamping mechanism 6 near both ends. The clamping mechanism 6 firmly fixes the transverse support frame 2 to the edge of the combined steel formwork 1 to ensure that the transverse support frame 2 does not shift during the pouring process.

[0022] In actual installation, the combined steel formwork 1 is first assembled according to the construction drawings to form a pouring area that meets the requirements. Then, the horizontal support frames 2 are placed one by one on top of the combined steel formwork 1, and the position of the horizontal support frames 2 is adjusted to correspond with the preset position of the embedded part 0. Then, the upper threaded part of the embedded part 0 is inserted through the through hole of the horizontal support frame 2, and the lower limit nut 3 and the upper limit nut 4 are screwed in sequence to achieve the initial positioning and fixation of the embedded part 0 through bidirectional clamping. Next, the adjacent collinear horizontal support frames 2 are connected and fixed with the horizontal connecting frame 5 to form an overall horizontal support structure. Finally, the two ends of each horizontal support frame 2 are fixed to the edge of the combined steel formwork 1 by the clamping mechanism 6 to complete the assembly of the entire set of tools. This structure connects multiple horizontal support frames 2 into a whole through the horizontal connecting frame 5, and together with the clamping mechanism 6 and the fixing of the combined steel formwork 1, it forms a unified batch fixed support system, which can simultaneously realize the positioning and fixing of multiple embedded parts 0, solves the problem of having to operate a single embedded part separately in the existing technology, greatly improves construction efficiency, and meets the needs of large-scale embedded construction.

[0023] Furthermore, the clamping mechanism 6 includes a step-by-step clamping buckle 7 and a clamping plate 8 located above the step-by-step clamping buckle 7. One side of the clamping plate 8 is clamped and fixed to the bottom of the transverse support frame 2, and the other side of the clamping plate 8 is provided with a stud 9. The lower end of the stud 9 passes through the pressure plate 10 of the step-by-step clamping buckle 7 and abuts against the upper plane of the edge of the combined steel template 1. The latch 11 of the step-by-step clamping buckle 7 is pressed against the lower plane of the edge of the combined steel template 1.

[0024] In this embodiment, as Figure 3 , Figure 5 As shown, the step-by-step clamping buckle 7 is an existing mature fastening component, which includes a pressure plate 10 and a movable latch 11. The component can be clamped by the cooperation of the latch 11 and the pressure plate 10. The clamping plate 8 is a rectangular plate structure. One side of it is provided with a clamping structure that is adapted to the bottom of the transverse support frame 2, which can be tightly clamped to the bottom of the transverse support frame 2. The other side of the clamping plate 8 is provided with a threaded hole in the vertical direction. The stud 9 is threaded into the threaded hole. The length of the stud 9 is greater than the distance from the clamping plate 8 to the upper surface of the combined steel template 1. Its lower end is machined into a flat end face so as to fully contact the upper surface of the combined steel template 1. During assembly, first, one side of the clamping plate 8 is clamped onto the bottom of the transverse support frame 2. Then, the step-by-step fastener 7 is placed below the edge of the combined steel template 1, so that the latch 11 clamps the lower surface of the combined steel template 1. Then, the stud 9 is passed through the threaded hole of the clamping plate 8 and the pressure plate 10 of the step-by-step fastener 7. The stud 9 is screwed so that its lower end tightly abuts against the upper surface of the combined steel template 1. Through the upper and lower clamping action of the stud 9 and the latch 11 of the step-by-step fastener 7, the clamping mechanism 6 is fixed to the combined steel template 1, thereby firmly locking the transverse support frame 2 above the combined steel template 1.

[0025] In the above structure, the clamping mechanism 6 adopts a combination of step-by-step fasteners 7, studs 9, and clamping plates 8, which eliminates the need for complex welding or binding operations, making assembly and disassembly more convenient and reducing the operational difficulty for construction personnel. Moreover, through the bidirectional clamping method, the transverse support frame 2 and the combined steel formwork 1 can be firmly fixed, effectively preventing the transverse support frame 2 from shifting during the pouring process and ensuring the positioning accuracy of the embedded parts 0.

[0026] Specifically, the clamping plate 8 is provided with a slot for engaging with the bottom of the transverse support frame 2, with a flange 12 on the upper edge of one side of the slot and a rubber pad 13 on the other side of the slot.

[0027] In this embodiment, as Figure 4As shown, the slot on the clamping plate 8 is opened horizontally, and the width of the slot is adapted to the thickness of the transverse support frame 2 to ensure that the clamping plate 8 can be tightly engaged at the bottom of the transverse support frame 2. The upper edge of one side of the slot extends outward to form a flange 12, which is perpendicular to the body of the clamping plate 8. When the clamping plate 8 is engaged at the bottom of the transverse support frame 2, the flange 12 can abut against the upper surface of one side of the transverse support frame 2, forming upper and lower limits to prevent the clamping plate 8 from falling off the transverse support frame 2. A rubber pad 13 is attached to the inner wall of the other side of the slot. The rubber pad 13 is 2-5mm thick and made of highly elastic rubber. When the clamping plate 8 is engaged with the transverse support frame 2, the rubber pad 13 is compressed and undergoes elastic deformation, filling the gap between the slot and the transverse support frame 2, and increasing the friction between the clamping plate 8 and the transverse support frame 2.

[0028] In the above structure, the flange 12 enhances the stability of the connection between the clamping plate 8 and the transverse support frame 2, preventing the clamping plate 8 from slipping during assembly and use; the rubber pad 13 not only improves the tightness of the clamping, but also plays a buffering role, reducing the impact of casting vibration on the connection structure, and at the same time preventing wear caused by hard contact between the clamping plate 8 and the transverse support frame 2.

[0029] In addition, the two relatively parallel transverse support frames 2 are connected by a longitudinal support mechanism, which includes a longitudinal support frame 14 and a longitudinal connecting frame 15. The longitudinal support frame 14 is fixed perpendicularly to the transverse support frame 2, and the two ends of the longitudinal connecting frame 15 are respectively fixed to the ends of the two longitudinal support frames 14 that are close to each other.

[0030] In this embodiment, as Figure 1 , Figure 8 As shown, the longitudinal support frame 14 is also made of steel profiles and is arranged perpendicularly to the transverse support frame 2. The longitudinal connecting frame 15 is a long strip-shaped component with an opening on one side. Its internal dimensions are adapted to the external dimensions of the longitudinal support frame 14. When there are two collinear longitudinal support frames 14, the two ends of the longitudinal connecting frame 15 are respectively fitted onto the close ends of the two adjacent longitudinal support frames 14, thereby realizing the connection of multiple longitudinal support frames 14 and enhancing the longitudinal stability of the entire support system.

[0031] In the above structure, the longitudinal support mechanism and the transverse support structure work together to form a three-dimensional support frame, thereby improving the overall rigidity and stability of the entire tool set. It can effectively resist the lateral pressure and vibration generated during concrete pouring, avoid deformation of the support system causing the 0 position of the embedded parts to shift, and further ensure the accuracy of the embedded construction.

[0032] More specifically, the end of the longitudinal support frame 14 is inserted into the interior of the longitudinal connecting frame 15, and a tightening bolt 16 is installed on the side wall of the longitudinal connecting frame 15. One end of the tightening bolt 16 penetrates into the interior of the longitudinal connecting frame 15 and presses the end of the longitudinal support frame 14.

[0033] In this embodiment, as Figure 8 As shown, the longitudinal connecting frame 15 has an open structure on one side and at both ends, with the inner diameter of the opening slightly larger than the outer diameter of the longitudinal support frame 14, ensuring that the ends of the longitudinal support frame 14 can be smoothly inserted. Both ends of the longitudinal connecting frame 15 have threaded holes, and tightening bolts 16 are screwed into the threaded holes. The length of the tightening bolts 16 is greater than the wall thickness of the longitudinal connecting frame 15, and an anti-slip pad is attached to one end of the bolt located inside the longitudinal connecting frame 15. During assembly, the ends of the two longitudinal support frames 14 are inserted into the openings at both ends of the longitudinal connecting frame 15, the insertion depth of the longitudinal support frames 14 is adjusted, and then the tightening bolts 16 at both ends are tightened, so that their ends are tightly pressed against the side wall of the longitudinal support frame 14 through the anti-slip pad, thus fixing the longitudinal support frame 14 to the longitudinal connecting frame 15.

[0034] The above structure adopts an insert-type connection with a tightening bolt 16 for fixation. This not only makes assembly convenient, but also allows for adjustment of the insertion depth of the longitudinal support frame 14 according to the actual construction spacing, adapting to different construction scenario requirements. The tightening bolt 16, together with the anti-slip pad, can ensure the firmness of the connection and prevent relative displacement between the longitudinal support frame 14 and the longitudinal connecting frame 15 due to vibration during the pouring process.

[0035] Furthermore, the inner wall of the longitudinal connecting frame 15 is provided with a protrusion extending in its own direction, and the longitudinal support frame 14 is provided with a groove extending in its own direction, the groove engaging with the protrusion of the longitudinal connecting frame 15.

[0036] In this embodiment, the inner wall of the longitudinal connecting frame 15 has two symmetrically distributed protrusions along its length. The protrusions are elongated structures with rectangular cross-sections. The side wall of the longitudinal support frame 14 has two grooves that fit the protrusions along its length. The grooves also have rectangular cross-sections. When the longitudinal support frame 14 is inserted into the longitudinal connecting frame 15, the protrusions on the inner wall of the longitudinal connecting frame 15 can accurately engage with the grooves of the longitudinal support frame 14, forming a guiding and positioning structure.

[0037] In the above structure, the engagement of the protrusion and the groove can guide the insertion direction of the longitudinal support frame 14, ensuring that the longitudinal support frame 14 and the longitudinal connecting frame 15 maintain the correct assembly posture.

[0038] In addition, a right-angle reinforcing member 17 is provided between the longitudinal support frame 14 and the transverse support frame 2, and the two right-angled sides of the right-angle reinforcing member 17 are fixed to the longitudinal support frame 14 and the transverse support frame 2 respectively.

[0039] In this embodiment, as Figure 9 As shown, the right-angled reinforcing member 17 has an L-shaped structure, with two fixing holes on each of its two right-angled sides. The right-angled reinforcing member 17 is installed at the connection between the longitudinal support frame 14 and the transverse support frame 2, with the two right-angled sides respectively abutting against the side walls of the longitudinal support frame 14 and the transverse support frame 2. The right-angled reinforcing member 17 is fixedly connected to the longitudinal support frame 14 and the transverse support frame 2 by bolts passing through the fixing holes. At least one right-angled reinforcing member 17 is installed at each connection, and the number can be increased according to the stress conditions.

[0040] In the above structure, the right-angle reinforcing member 17 can effectively enhance the strength and rigidity of the connection between the longitudinal support frame 14 and the transverse support frame 2, disperse the force at the connection, and prevent the connection from deforming or being damaged due to excessive local force during the pouring process, thereby further improving the load-bearing capacity and stability of the entire support system.

[0041] like Figure 6 The outermost edge of the combined steel template 1 is fixed to one end of the corresponding transverse support frame 2 by a positioning and clamping mechanism. The positioning and clamping mechanism includes a C-shaped frame 18 and a threaded rod 19. The threaded rod 19 is threaded to the upper end of the C-shaped frame 18 and is externally fitted with a lower clamping nut 20 and an upper clamping nut 21. The upper end of the threaded rod 19 is a T-shaped knob 22, and the lower end of the threaded rod 19 is an upper clamp 23. Correspondingly, the lower end of the positioning and clamping mechanism is a lower clamp 24. The lower clamp 24 is located at the bottom of the edge of the combined steel template 1, and the upper clamp 23 is located above the edge of the combined steel template 1. The lower clamping nut 20 and the upper clamping nut 21 abut against the bottom and top of the transverse support frame 2, respectively.

[0042] In this embodiment, as Figure 6 , Figure 7As shown, the opening of the C-shaped frame 18 faces the edge of the combined steel formwork, and the opening size is larger than the edge thickness of the combined steel formwork 1. The threaded rod 19 passes through the upper threaded cylinder of the C-shaped frame 18 and engages with the threaded hole on the threaded cylinder. A T-shaped knob 22 is welded to the upper end of the threaded rod 19 for easy manual tightening by construction personnel. The lower end is fixedly connected to an upper clamp 23 by bolts. The upper clamp 23 is a rectangular steel plate with an anti-slip rubber pad affixed to its lower surface. The lower clamp 24 of the positioning and clamping mechanism is integrally formed or fixedly connected to the lower end of the C-shaped frame 18, and its upper surface is also covered with an anti-slip rubber pad. During assembly, the opening of the C-shaped frame 18 is clamped onto the edge of the combined steel template 1, so that the lower clamp 24 is located at the bottom of the edge of the combined steel template 1 and the upper clamp 23 is located above the edge of the combined steel template 1. Then, one end of the transverse support frame 2 (which has an opening) is placed below the upper threaded cylinder of the C-shaped frame 18. The lower clamping nut 20 is screwed down to abut against the bottom of the transverse support frame 2, and the upper clamping nut 21 is screwed down to abut against the top of the transverse support frame 2. The transverse support frame 2 is clamped by the upper and lower nuts. Finally, the T-shaped knob 22 is screwed down to move the threaded rod 19 downward, so that the upper clamp 23 and the lower clamp 24 clamp the edge of the combined steel template 1, thus completing the fixing of the positioning and clamping mechanism.

[0043] In the above structure, the positioning and clamping mechanism is specifically designed to fix the outermost combined steel template 1 and the transverse support frame 2. Through double clamping (clamping of the transverse support frame 2 and clamping of the combined steel template 1), precise positioning and firm fixation are achieved, preventing the outermost support structure from shifting due to lack of lateral constraint, ensuring the edge stability of the entire support system, and further guaranteeing the consistency of positioning accuracy of all embedded parts 0.

[0044] This invention also discloses a process for synchronous casting of embedded parts, which uses the aforementioned tools for synchronous casting of embedded parts and includes the following steps: Step 1: Determine the distribution location and quantity of the embedded parts 0 and the assembly range of the combined steel formwork 1 according to the construction drawings. Assemble multiple combined steel formwork 1s to form the pouring operation surface. Adjust the position and level of the combined steel formwork 1 to ensure that it meets the requirements of the construction specifications. Step 2: First, place each individual horizontal support frame 2 on top of the combined steel formwork 1, and determine the precise position of each horizontal support frame 2 by measuring and laying out lines; then, insert the upper threaded part of the embedded part 0 through the through hole of the corresponding horizontal support frame 2, and tighten the lower limit nut 3 and upper limit nut 4 to precisely adjust the height and verticality of the embedded part 0 and lock it in place; then, use the horizontal connecting frame 5 to connect and fix adjacent collinear horizontal support frames 2, and connect the relatively parallel horizontal support frames 2 through the longitudinal support mechanism to form an overall support system; finally, use the clamping mechanism 6 to fix both ends of each horizontal support frame 2 to the edge of the combined steel formwork 1, and use the positioning clamping mechanism to fix the outermost combined steel formwork 1 and the horizontal support frame 2, completing the fixing of the entire device; Step 3: After checking and confirming the position, height, verticality and stability of all embedded parts 0 and the support system, continuously pour concrete into the combined steel formwork 1. During the pouring process, avoid direct impact on the embedded parts 0 and the support system, and at the same time do a good job of concrete vibration to ensure the pouring quality. Step 4: After the concrete has cured to the design strength, first remove the positioning clamping mechanism and clamping mechanism 6, then remove the longitudinal connecting frame 15, longitudinal support frame 14 and transverse connecting frame 5, and finally tighten the upper limit nut 4 and lower limit nut 3 to separate the transverse support frame 2 from the embedded part 0, thus completing the removal of the formwork and fixing device. The embedded part 0 is kept firmly connected to the concrete structure for subsequent equipment installation.

[0045] The above-mentioned casting process, in conjunction with the supporting tools, enables the synchronous positioning, fixing, and casting of embedded parts 0 in sections and groups, significantly reducing the procedures for individual embedded parts, shortening the construction cycle, and improving construction efficiency. At the same time, the precise positioning structure and stable support system ensure the installation accuracy of all embedded parts 0, avoiding rework caused by embedded deviations in the later stages and guaranteeing the quality of the project.

[0046] Furthermore, in traditional pre-installation methods, embedded parts are often fixed at a single point using wire binding or independent trestles. This results in insufficient overall stability of the fixing structure. During concrete pouring and vibration, the embedded parts are susceptible to horizontal or vertical displacement due to lateral pressure, vibration, and other external forces, making it difficult to meet high-precision construction requirements. In contrast, this device forms a three-dimensional integrated support system. The lower limit nut 3 and upper limit nut 4 limit the upper and lower positions of each embedded part 0. Combined with multi-point strong fixing using lateral constraints, it effectively resists various external force interferences during the pouring process, ensuring that the embedded part 0 maintains its preset position, height, and verticality throughout the entire construction process, significantly improving the consistency of batch pre-installation accuracy. On the other hand, the combined steel formwork 1, transverse support frame 2, longitudinal support frame 14, transverse connecting frame 5, and longitudinal connecting frame 15 of this device are all designed to be detachable. After construction, they can be completely disassembled and recycled. After simple cleaning and maintenance, they can be reused for subsequent pre-installation projects of different scales and scenarios, reducing material waste costs and the labor costs of repeated processing.
