Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, specifically to a concrete splicing template. Background Technology

[0002] Concrete splicing formwork, as the core temporary support structure for concrete forming in construction engineering, has been widely used in high-rise building walls, bridge piers, large stadiums and other engineering scenarios due to its advantages such as modular assembly, high turnover and high construction efficiency. Especially in projects with complex wind environments such as super high-rise buildings and cross-sea bridges, the formwork system must simultaneously meet multiple requirements such as splicing stability, concrete forming quality and resistance to wind load impact. The rationality of its structural design directly determines the construction safety and project economy. Currently, the technological development of concrete splicing formwork focuses on optimizing splicing efficiency and sealing performance. However, existing technologies still have certain shortcomings in terms of wind load adaptability design: most existing air guiding structures only achieve "single-time airflow guidance," that is, guiding airflow in a single direction through the channel without setting a secondary diversion mechanism. When strong winds impact the formwork, even if some airflow is guided by the air guiding channel, residual wind pressure will still accumulate in the channel and be transmitted to the splicing node through the formwork joint, causing the splicing blocks to loosen and the sealing gasket to deform, which in turn leads to grout leakage. Additional reinforcement supports (such as denser uprights and additional tie bolts) are required, which significantly increases construction costs. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a concrete splicing formwork that solves the problem that when airflow is guided to flow in a single direction through a trough, residual wind pressure will still accumulate in the trough even if some airflow is guided by the air guide trough. When the wind blows towards the formwork body, the airflow first enters the air guide trough and is guided and diverted. Subsequently, some airflow flows laterally through the ventilation trough, further dispersing the airflow energy and ultimately reducing the impact of wind load on the formwork system. The trapezoidal inclined side of the air guide trough can guide the airflow along the trough, balancing the guiding effect and structural stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a concrete splicing template, comprising a template assembly, a stabilizing assembly, and a splicing assembly. The template assembly includes a template body, the stabilizing assembly includes a stabilizing wall panel and a snap-fit ​​ring strip, and the splicing assembly includes a splicing clip and a splicing groove. A positioning plate is integrally formed vertically at one end of the template body along its length direction. The end of the positioning plate away from the template body extends to form a splicing plate. A second positioning plate is integrally formed vertically at the other end of the template body away from the positioning plate. The end of the second positioning plate away from the template body extends to form a splicing plate. The inner side of the stabilizing wall panel along the thickness direction of the template body is the rear end. The rear end of the stabilizing wall panel is vertically connected to an insert plate by full welding. The height of the insert plate is the same as the height of the stabilizing wall panel.

[0005] The beneficial effects of this utility model are as follows: when the wind blows towards the main body of the template, the airflow first enters the air guide groove and is guided and diverted. Then, part of the airflow flows laterally through the ventilation groove, further dispersing the airflow energy and ultimately reducing the impact of wind load on the template system. The trapezoidal inclined side of the air guide groove can guide the airflow along the groove, balancing the guiding effect and structural stability.

[0006] To provide a precise splicing reference for stable components through the symmetrical arrangement of positioning plate one and positioning plate two, while also distributing the stress on the splicing nodes: As a further improvement to the above technical solution: the thickness, height and length of the first positioning plate and the second positioning plate are the same, and the inner side of the first positioning plate and the second positioning plate are provided with positioning inner holes with a diameter of M16. They are arranged at equal intervals along the height direction of the first positioning plate and the second positioning plate, and the axis of the positioning inner holes is perpendicular to the surface of the template body.

[0007] The beneficial effects of this improvement are as follows: After the main body of two adjacent templates is spliced, the stabilizing wall panel is vertically inserted into the groove formed by the adjacent positioning plate 1 and positioning plate 2 along the height direction of the main body of the template. When inserting, ensure that the two sides of the stabilizing wall panel are completely in contact with the outer walls of positioning plate 1 and positioning plate 2 respectively. Then, M16 bolts are used to pass through the clearance screw holes and positioning inner holes of the stabilizing wall panel in sequence to achieve rigid splicing of the stabilizing wall panel with the adjacent positioning plate 1 and positioning plate 2. Through the symmetrical setting of positioning plate 1 and positioning plate 2, a precise splicing benchmark is provided for the stabilizing components, while dispersing the force of the splicing nodes.

[0008] To enable rapid positioning and splicing of adjacent template components, the splicing blocks and splicing slots use a transition fit to prevent lateral movement after splicing. As a further improvement to the above technical solution: the dimensions of the splicing plate one are the same as the thickness, height and length of the splicing plate two, and a splicing block is vertically welded to the end of the splicing plate one away from the positioning plate one, and a 15° guide slope is provided at the end of the splicing block one away from the splicing plate one.

[0009] The beneficial effects of this improvement are as follows: When splicing the template components, the first template component is placed on a leveled support base. The levelness of the template body is calibrated with a level and the verticality is calibrated with a straightedge. Temporary supports are used for fixation. The splicing clip of the second template component is aligned with the splicing slot of the first template component and inserted vertically along the height direction of the template body until the inner side wall of the first splicing plate of the second template is completely flush with the outer side wall of the second splicing plate of the first template. A right-angle ruler is used to check the flatness of the end faces of the two template bodies, realizing the rapid positioning and splicing of adjacent template components. The splicing clip and the splicing slot adopt a transition fit to avoid lateral movement after splicing.

[0010] To achieve a dual guarantee of rigid fixation and elastic sealing at the splicing joints, effectively preventing grout leakage during concrete pouring: As a further improvement to the above technical solution: the height of the stabilizing wall panel is consistent with the height of the template body, the height of the inserting upright plate is consistent with the height of the splicing two plates, and the inner side of the stabilizing wall panel is provided with clearance screw holes, the diameter and spacing of the clearance screw holes are matched with the positioning inner holes, and the clearance screw holes are countersunk holes.

[0011] The beneficial effects of this improvement are as follows: After the initial splicing of two adjacent template components is completed, the insert plate is vertically inserted into the groove formed by the adjacent splicing plate 2 and splicing plate 1 along the height direction of the template body. When inserting, ensure that the top surface of the insert plate is flush with the top surface of the splicing plate 2 and the bottom surface is flush with the bottom surface of the splicing plate 2. Bolts are used to sequentially pass through the clearance screw holes and positioning inner holes. After tightening, the bolt heads are completely sunk into the clearance screw holes, realizing the rigid connection of one stable component to two adjacent template components at the same time. At the same time, the contact surface of the insert plate with the splicing plate 2 and splicing plate 1, together with the elastic seal of the subsequent snap ring and ring gasket, form a double guarantee of rigid fixation and elastic sealing of the splicing node, effectively preventing grout leakage during concrete pouring.

[0012] In order to disperse the impact of the lateral pressure of the concrete on the splice joint through the surface contact between the locking block and the locking slot: As a further improvement to the above technical solution: the size of the splicing block matches the size of the splicing slot, the splicing slot is opened on the side of the splicing plate away from the positioning plate, and the inner wall of the slot is sandblasted.

[0013] The beneficial effects of this improvement are as follows: by opening the splicing slot, a unique insertion path is provided for the splicing block, avoiding splicing misalignment. At the same time, the surface contact between the block and the slot disperses the impact of the concrete lateral pressure on the splicing joint.

[0014] To limit the lateral displacement of adjacent template bodies and enhance the shear strength of the splicing joints: As a further improvement to the above technical solution: an annular splicing groove is provided on the inner side of the splicing plate, and the splicing groove is continuously distributed along the circumference of the splicing plate. The end of the embedded upright plate away from the stable wall plate is integrally vulcanized with a snap-fit ​​strip, and the cross-sectional diameter of the snap-fit ​​strip is consistent with the diameter of the splicing groove.

[0015] The beneficial effects of this improvement are as follows: after the initial splicing of two adjacent template bodies is completed, the splicing groove of the first splicing plate is completely aligned and connected with the splicing groove of the second splicing plate. When the snap-fit ​​strip is inserted into the connected splicing groove along with the inserting upright plate, the snap-fit ​​strip and the splicing groove form an interference fit, which is used to limit the lateral displacement of the adjacent template bodies, while enhancing the shear strength of the splicing node and further improving the splicing stability.

[0016] To fill the tiny gaps between the splicing grooves and snap-fit ​​strips through elastic deformation, while simultaneously blocking the seepage path of concrete slurry: As a further improvement to the above technical solution: the inner side of the splicing plate 2 is provided with an annular splicing groove consistent with that of the splicing plate 1. The end of the snap-fit ​​ring strip away from the inserting upright plate is integrally vulcanized with a ring strip pad ring. The ring strip pad ring is a EPDM rubber pad layer with a Shore hardness of 70A and a thickness of 5mm. The outer diameter of the ring strip pad ring is 2mm larger than the diameter of the splicing groove.

[0017] The beneficial effects of this improvement are as follows: when the two adjacent template bodies are initially connected, the splicing grooves of the splicing plate one and the splicing plate two are fully connected. When the snap ring strip is inserted into the connected splicing groove, the ring strip gasket is inserted synchronously with the snap ring strip. After insertion, the ring strip gasket undergoes compression deformation in the splicing groove. Through elastic deformation, it fills the tiny gap between the splicing groove and the snap ring strip, while blocking the penetration path of the concrete slurry and ensuring the sealing performance of the splicing joint.

[0018] To ensure that the trapezoidal bevel of the air guide duct can guide the airflow along the duct body and balance the airflow guiding effect with structural stability: As a further improvement to the above technical solution: the inner wall of the front part of the template body is provided with air guide grooves at equal intervals along the length direction. The depth of the air guide groove is 1 / 5 of the thickness of the template body, and a 50mm thick template body substrate is retained at the bottom of the air guide groove. The spacing between adjacent air guide grooves is four times its width. The cross-section of the air guide groove is an isosceles trapezoid when viewed from above. The inner wall of the air guide groove is uniformly coated with a water-based concrete release agent. The air guide groove is centrally located along the height direction of the template body and its height is 1 / 2 of the height of the template body. The inner wall of the air guide groove is symmetrically provided with ventilation grooves, which are rectangular in cross-section and are arranged at equal intervals along the length direction of the air guide groove.

[0019] The beneficial effects of this improvement are as follows: when the wind blows towards the main body of the formwork, the airflow first enters the air guide channel and is guided and diverted. Subsequently, part of the airflow flows laterally through the ventilation channel, further dispersing the airflow energy and ultimately reducing the impact of wind load on the formwork system. The trapezoidal inclined side of the air guide channel can guide the airflow along the channel, balancing the guiding effect and structural stability.

[0020] In summary, the beneficial effects of this case are as follows: the trapezoidal inclined side of the air guide channel can guide the airflow along the channel body, balancing the air guiding effect and structural stability; the elastic deformation fills the tiny gaps between the splicing ring groove and the snap ring strip, while blocking the seepage path of the concrete slurry and ensuring the sealing performance of the splicing joint.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0029] like Figure 1-5As shown, a concrete splicing formwork includes a formwork assembly 1, a stabilizing assembly 2, and a splicing assembly 3. The formwork assembly 1 includes a formwork body 11. The stabilizing assembly 2 includes a stabilizing wall panel 21 and a snap-fit ​​ring strip 24. The splicing assembly 3 includes a splicing clip 31 and a splicing groove 33. A positioning plate 12 is integrally formed vertically at one end of the formwork body 11 along its length. The end of the positioning plate 12 away from the formwork body 11 extends to form a splicing plate 13. A second positioning plate 14 is integrally formed vertically at the other end of the formwork body 11 away from the positioning plate 12. The end of the second positioning plate 14 away from the formwork body 11 extends to form a splicing plate 15. The inner side of the stabilizing wall panel 21 along the thickness direction of the formwork body 11 is the rear end. The rear end of the stabilizing wall panel 21 is vertically connected to an insert plate 22 by full welding. The height of the insert plate 22 is the same as the height of the stabilizing wall panel 21.

[0030] The first positioning plate 12 and the second positioning plate 14 have the same thickness, height, and length. Both the first positioning plate 12 and the second positioning plate 14 have positioning inner holes 16 on their inner sides. The diameter of the positioning inner holes 16 is M16, and they are arranged at equal intervals along the height direction of the first positioning plate 12 and the second positioning plate 14. The axis of the positioning inner holes 16 is perpendicular to the surface of the template body 11. After the two adjacent template bodies 11 are spliced ​​together, the stabilizing wall panel 21 is vertically inserted into the adjacent first positioning plate 12 and the second positioning plate 14 along the height direction of the template body 11. When the groove formed by the second positioning plate 14 is inserted, it is ensured that the two sides of the stabilizing wall plate 21 are completely in contact with the outer walls of the first positioning plate 12 and the second positioning plate 14 respectively. Then, M16 bolts are used to pass through the clearance screw holes 23 and the positioning inner holes 16 of the stabilizing wall plate 21 in sequence to achieve rigid splicing of the stabilizing wall plate 21 with the adjacent first positioning plate 12 and the second positioning plate 14. Through the symmetrical arrangement of the first positioning plate 12 and the second positioning plate 14, a precise splicing benchmark is provided for the stabilizing component 2, while dispersing the force of the splicing node.

[0031] The dimensions of the first splicing plate 13 are the same as the thickness, height, and length of the second splicing plate 15. A splicing block 31 is vertically welded to the end of the first splicing plate 13 away from the positioning plate 12. The end of the splicing block 31 away from the first splicing plate 13 is provided with a 15° guide slope. When splicing the template assembly 1, the first template assembly 1 is placed on the leveled support base. The levelness of the template body 11 is calibrated by a level and the verticality is calibrated by a straightedge. Temporary supports are used for fixation. The splicing block 31 of the second template assembly 1 is aligned with the splicing slot 33 of the first template assembly 1 and vertically inserted along the height direction of the template body 11 until the inner side wall of the first splicing plate 13 of the second template is completely in contact with the outer side wall of the second splicing plate 15 of the first template. A right-angle ruler is used to check the flatness of the end faces of the two template bodies 11, so as to realize the rapid positioning and splicing of the two adjacent template assemblies 1. The splicing block 31 and the splicing slot 33 adopt a transition fit to avoid lateral movement after splicing.

[0032] The height of the stabilizing wall panel 21 is the same as the height of the template body 11, and the height of the inserting upright plate 22 is the same as the height of the splicing second plate 15. The inner side of the stabilizing wall panel 21 is provided with clearance screw holes 23, the diameter and spacing of which match the positioning inner hole 16, and the clearance screw holes 23 are countersunk holes. After the initial splicing of two adjacent template components 1 is completed, the inserting upright plate 22 is vertically inserted into the groove formed by the adjacent splicing second plate 15 and splicing first plate 13 along the height direction of the template body 11. When inserting, ensure that the top surface of the inserting upright plate 22 is... The top and bottom surfaces of the two-piece splicing plate 15 are flush with each other. Bolts are sequentially inserted through the clearance screw holes 23 and the positioning inner holes 16. After tightening, the bolt heads are completely sunk into the clearance screw holes 23, achieving a rigid connection between one stable component 2 and two adjacent template components 1. At the same time, the vertical plate 22 is inserted into the mating surfaces of the two-piece splicing plate 15 and the first-piece splicing plate 13. With the subsequent elastic sealing of the snap ring strip 24 and the ring strip washer 25, a double guarantee of rigid fixation and elastic sealing of the splicing node is formed, effectively preventing grout leakage during concrete pouring.

[0033] The size of the splicing block 31 matches the size of the splicing slot 33. The splicing slot 33 is opened on the side of the splicing plate 15 away from the positioning plate 14, and the inner wall of the slot is sandblasted. The opening of the splicing slot 33 provides a unique insertion path for the splicing block 31, avoiding splicing misalignment. At the same time, the surface contact between the block and the slot disperses the impact of the concrete lateral pressure on the splicing node.

[0034] The inner side of the splicing plate 13 is provided with an annular splicing groove 32, which is continuously distributed along the perimeter of the splicing plate 13. The end of the inserting upright plate 22 away from the stable wall plate 21 is integrally vulcanized with a snap-fit ​​strip 24, the cross-sectional diameter of which is the same as the diameter of the splicing groove 32. After the two adjacent template bodies 11 are initially spliced, the splicing groove 32 of the splicing plate 13 and the splicing groove 32 of the splicing plate 15 are completely aligned and connected. When the snap-fit ​​strip 24 is inserted into the connected splicing groove 32 along with the inserting upright plate 22, the snap-fit ​​strip 24 and the splicing groove 32 form an interference fit, which is used to limit the lateral displacement of the adjacent template bodies 11, while enhancing the shear strength of the splicing node and further improving the splicing stability.

[0035] The inner side of the second splicing plate 15 is provided with an annular splicing groove 32 that is consistent with the first splicing plate 13. The end of the snap-fit ​​ring strip 24 away from the embedded upright plate 22 is integrally vulcanized and connected to a ring strip pad 25. The ring strip pad 25 is a EPDM rubber pad with a Shore hardness of 70A and a thickness of 5mm. The outer diameter of the ring strip pad 25 is 2mm larger than the diameter of the splicing groove 32. When the two adjacent template bodies 11 are initially connected, the splicing groove 32 of the first splicing plate 13 and the second splicing plate 15 are completely connected. When the snap-fit ​​ring strip 24 is inserted into the connected splicing groove 32, the ring strip pad 25 is inserted synchronously with the snap-fit ​​ring strip 24. After insertion, the ring strip pad 25 undergoes compression deformation in the splicing groove 32. Through elastic deformation, it fills the tiny gap between the splicing groove 32 and the snap-fit ​​ring strip 24, while blocking the penetration path of the concrete slurry and ensuring the sealing performance of the splicing joint.

[0036] The inner front wall of the template body 11 is provided with air guide grooves 111 at equal intervals along its length. The depth of the air guide grooves 111 is 1 / 5 of the thickness of the template body 11, and a 50mm thick template body substrate is retained at the bottom of the air guide grooves 111. The spacing between adjacent air guide grooves 111 is four times its width. The cross-section of the air guide grooves 111 in plan view is an isosceles trapezoid. The inner wall of the air guide grooves 111 is uniformly coated with a water-based concrete release agent. The air guide grooves 111 are centrally located along the height direction of the template body 11, and their height is equal to the height of the template body 11. Half the height of the formwork body 11, the inner wall of the air guide 111 is symmetrically provided with ventilation slots 112. The ventilation slots 112 have a rectangular cross section and are arranged at equal intervals along the length of the air guide 111. When the wind blows towards the formwork body 11, the airflow first enters the air guide 111 and is guided and diverted. Then, part of the airflow flows laterally through the ventilation slots 112, further dispersing the airflow energy and ultimately reducing the impact of wind load on the formwork system. The trapezoidal inclined side of the air guide 111 can guide the airflow along the channel, balancing the guiding effect and structural stability.

[0037] The working principle of this utility model is as follows: When assembling the template assembly 1, the first template assembly 1 is placed on a leveled support base. The levelness of the template body 11 is calibrated using a level and the verticality is calibrated using a straightedge. Temporary supports are used for fixation. The splicing block 31 of the second template assembly 1 is aligned with the splicing slot 33 of the first template assembly 1 and vertically inserted along the height direction of the template body 11 until the inner side wall of the splicing plate 13 of the second template is completely flush with the outer side wall of the splicing plate 15 of the first template. A right-angle ruler is used to check the flatness of the end faces of the two template bodies 11, thus achieving rapid positioning and splicing of adjacent template assemblies 1. The splicing block 31 and the splicing slot 33 adopt a transition fit. To prevent lateral movement after splicing, when two adjacent template bodies 11 are initially connected, the splicing grooves 32 of the first splicing plate 13 and the second splicing plate 15 are fully connected. When the snap-fit ​​ring strip 24 is inserted into the connected splicing groove 32, the ring strip washer 25 is inserted synchronously with the snap-fit ​​ring strip 24. After insertion, the ring strip washer 25 undergoes compression deformation within the splicing groove 32, filling the tiny gap between the splicing groove 32 and the snap-fit ​​ring strip 24 through elastic deformation, while blocking the penetration path of concrete grout and ensuring the sealing performance of the splicing joint. At the same time, the stabilizing wall panel 21 is vertically inserted along the height direction of the template body 11 into the groove formed by the adjacent positioning first plate 12 and positioning second plate 14. During insertion, ensure that the stabilizing wall panel 21... The two sides are completely fitted to the outer walls of positioning plate 12 and positioning plate 24 respectively. Then, M16 bolts are used to pass through the clearance screw holes 23 and positioning inner holes 16 of the stabilizing wall plate 21 in sequence to achieve rigid splicing between the stabilizing wall plate 21 and the adjacent positioning plate 12 and positioning plate 24. The symmetrical arrangement of positioning plate 12 and positioning plate 24 provides a precise splicing benchmark for the stabilizing component 2, while dispersing the force on the splicing node. After the two adjacent template bodies 11 are initially spliced, the splicing groove 32 of splicing plate 13 and the splicing groove 32 of splicing plate 25 are completely aligned and connected. When the snap-fit ​​strip 24 is inserted into the connected splicing groove 32 along with the inserting upright plate 22, the snap-fit ​​strip 24 and the splicing plate 25 are connected. The groove 32 forms an interference fit to limit the lateral displacement of adjacent formwork bodies 11, while enhancing the shear strength of the splicing joint and further improving the stability of the splicing. The opening of the splicing slot 33 provides a unique insertion path for the splicing block 31, avoiding splicing misalignment. At the same time, the surface contact between the block and the slot disperses the impact of the concrete lateral pressure on the splicing joint. When the wind blows towards the formwork body 11, the airflow first enters the air guide duct 111 and is guided and diverted. Subsequently, part of the airflow flows laterally through the ventilation duct 112, further dispersing the airflow energy and ultimately reducing the impact of wind load on the formwork system. The trapezoidal inclined side of the air guide duct 111 can guide the airflow along the duct body, balancing the guiding effect and structural stability.
