Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building technology, specifically relating to a prefabricated component of a core-insulated panel with a steel mesh frame without studs. Background Technology
[0002] Currently, insulated walls are typically constructed using precast components. These components include insulation boards and multiple sets of steel mesh on both sides of the insulation boards. The precast components are prefabricated in the factory and then transported to the construction site for installation. The construction is convenient because formwork is erected on both sides of the precast components, and then the concrete is poured on-site.
[0003] To prevent the steel mesh from shifting during the pouring process, the precast components also include tie bars. The tie bars, which pass through the insulation board, fix the steel mesh on both sides of the insulation board. The two ends of the tie bars abut against the template on both sides, thereby limiting and fixing the steel mesh. However, since the tie bars are made of metal and have thermal conductivity, and since the tie bars pass through the insulation board, they will form thermal bridges, affecting the insulation performance of the insulation wall. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a prefabricated sandwich insulation panel component without studs and tie bars. The separate tie bars are connected using plastic connecting components, avoiding direct contact between the fixing and insertion parts of the tie bars, thus preventing thermal bridging. This ensures the insulation performance of the insulation wall while retaining the function of the tie bars themselves.
[0005] The specific technical solution adopted in this utility model is as follows:
[0006] A prefabricated component of a core-insulated panel with a steel mesh frame without studs includes multiple sets of prefabricated units connected end to end. Each prefabricated unit includes an insulation panel, a steel mesh frame, and tie bars. The tie bars include a fixed part and an insert part that are separately arranged. The adjacent ends of the fixed part and the insert part are separated and connected by a connecting component. The upper-level prefabricated unit and the lower-level prefabricated unit are arranged adjacent to each other vertically and connected by binding between adjacent steel mesh frames.
[0007] The connecting assembly includes a fixed sleeve and a plug rod that mates with the fixed sleeve. The closed end of the fixed sleeve is fixedly connected to the fixed part of the tie bar. An inclined limiting ring is provided inside the fixed sleeve, with the limiting ring inclined toward the fixed part. The end of the plug rod is fixedly connected to the plug part of the tie bar. The plug rod is provided with a barbed claw that hooks and mates with the limiting ring, with the claw inclined toward the plug part. The fixed part and the plug part of the tie bar are connected by the engagement of the limiting ring and the claw.
[0008] The hook claws are arranged in a ring array with the axis of the plug rod as the center. The diameter of the plug rod is smaller than the inner ring diameter of the limiting ring. The distance between the top of the hook claw and the axis of the plug rod is greater than the inner ring radius of the limiting ring and smaller than the outer ring radius of the limiting ring.
[0009] The limiting rings are arranged in multiple sets at equal intervals along the axial direction of the fixed sleeve.
[0010] The steel reinforcement mesh includes a first steel reinforcement mesh, a second steel reinforcement mesh, and a third steel reinforcement mesh arranged at intervals along the horizontal direction. The first steel reinforcement mesh and the second steel reinforcement mesh form an insulation chamber for placing the insulation board, and the second steel reinforcement mesh and the third steel reinforcement mesh form a casting chamber. The tie bars pass through the insulation chamber and the casting chamber and are respectively tied to the tie bars of the first steel reinforcement mesh, the second steel reinforcement mesh, and the third steel reinforcement mesh.
[0011] The first steel mesh is connected to the second steel mesh by means of multiple intersecting diagonal steel bars, and the first steel mesh and the second steel mesh are clamped and fixed with the insulation board by means of diagonal steel bars.
[0012] Plastic caps are provided at the abutting ends of the fixing part and the template, and at the abutting ends of the insertion part and the template, respectively. The two ends of the tie bar abut against the template by means of the plastic caps.
[0013] The beneficial effects of the utility model are:
[0014] The tie bar in this invention is a split structure, connected by a plastic connecting component, which avoids direct contact between the fixing part and the insertion part of the tie bar, thereby avoiding the generation of thermal bridges. While retaining the function of the tie bar itself, it ensures the thermal insulation performance of the insulation wall. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0021] Specific embodiments, such as Figure 1-4 As shown, this utility model provides a prefabricated component of a core-insulated panel 1 without studs and with a steel mesh frame. It includes multiple sets of prefabricated units connected end to end. Each prefabricated unit includes an insulation panel 1, a steel mesh frame, and tie bars. The tie bars include a fixing part 5 and a plug-in part 6 that are separately arranged. The adjacent ends of the fixing part 5 and the plug-in part 6 are separated and connected by a connecting component. The upper-level prefabricated unit and the lower-level prefabricated unit are arranged adjacent to each other vertically and connected by binding between adjacent steel mesh frames.
[0022] To prevent the steel mesh from shifting during the pouring process, the precast components also include tie bars. The tie bars passing through the insulation board 1 are used to fix and connect the steel mesh on both sides of the insulation board 1. The two ends of the tie bars abut against the templates 14 on both sides, thereby limiting and fixing the steel mesh. However, since the tie bars are made of metal and have thermal conductivity, and since the tie bars pass through the insulation board 1, they will form thermal bridges, affecting the thermal insulation performance of the insulation wall.
[0023] Therefore, the tie bar in this utility model is a split structure, which is connected by a plastic connecting component to avoid direct contact between the fixing part 5 and the plug-in part 6 of the tie bar, thereby avoiding the generation of thermal bridges. While retaining the function of the tie bar itself, it ensures the thermal insulation performance of the insulation wall.
[0024] like Figure 2-4 As shown, the connecting assembly includes a fixed sleeve 7 and a plug rod 8 that cooperates with the fixed sleeve 7. The closed end of the fixed sleeve 7 is fixedly connected to the fixing part 5 of the tie bar. An inclined limiting ring 9 is provided inside the fixed sleeve 7, and the limiting ring 9 is inclined toward the fixing part 5. The end of the plug rod 8 is fixedly connected to the plug part 6 of the tie bar. The plug rod 8 is provided with a barbed claw 10 that hooks and cooperates with the limiting ring 9. The claw 10 is inclined toward the plug part 6. The fixing part 5 and the plug part 6 of the tie bar are connected by the cooperation of the limiting ring 9 and the claw 10.
[0025] To ensure the strong connection between the fixing part 5 and the connecting part, the connecting component in this utility model adopts the form of a limiting ring 9 and a hook 10. Since the hook 10 and the limiting ring 9 are made of plastic, and plastic has a certain plasticity, when the plug rod 8 is inserted into the fixing sleeve 7, the plug rod 8 can be pushed forcefully, so that the hook 10 passes through the inner ring of the limiting ring 9. However, due to the inclined structure of the limiting ring 9 and the barbed structure of the hook 10, the hook 10 will hook with the limiting ring 9, thus preventing it from retracting and ensuring the connection strength between the fixing part 5 and the plug part 6.
[0026] In this utility model, the fixing sleeve 7 and the plug rod 8 are fixedly connected to the tie bar by bolts. The end of the plug part 6 is provided with two sets of fixing plates, and the plug rod 8 is bolted to the plug part 6 by bolts passing through the fixing plates.
[0027] like Figure 2 and Figure 4 As shown, at least two sets of hooks 10 are arranged in a ring array with the axis of the plug rod 8 as the center. The diameter of the plug rod 8 is smaller than the inner ring diameter of the limiting ring 9. The distance between the top of the hook 10 and the axis of the plug rod 8 is greater than the inner ring radius of the limiting ring 9 and smaller than the outer ring radius of the limiting ring 9.
[0028] like Figure 2-3 As shown, multiple sets of limiting rings 9 are evenly spaced along the axial direction of the fixing sleeve 7. Depending on the on-site construction requirements, the hook 10 can be used to select limiting rings 9 of different depths, thereby adjusting the length of the tie bar according to the required wall thickness.
[0029] like Figure 2 As shown, the connecting assembly also includes a limiting bolt 13. The fixing sleeve 7 is provided with limiting screw holes at equal intervals along the axial direction. The required limiting bolt 13 passes through the fixing sleeve 7 through the limiting screw holes, and the end of the plug rod 8 abuts against the limiting bolt 13. The limiting bolt 13 and the hook 10 together prevent the movement of the plug rod 8. The limiting ring 9 can prevent the hook 10 from retracting. However, when the pressure generated by pouring concrete is too large, it may cause the plug rod 8 to continue to move forward, causing the steel mesh to deform. Therefore, the limiting bolt 13 is provided. Through the obstruction of the limiting bolt 13 and the limiting ring 9, the plug rod 8 cannot move in either the forward or backward direction. By limiting the length of the plug rod 8, when the angle between the limiting ring 9 and the fixing sleeve 7 and the hook 10 abuts and hooks, the end of the plug rod 8 just passes through the next level limiting ring 9. At this time, the limiting bolt 13 can be installed in the corresponding limiting screw hole at the next level limiting ring 9, thereby locking the plug rod 8 and the fixing sleeve 7.
[0030] like Figure 1As shown, the steel reinforcement mesh includes a first steel reinforcement mesh 2, a second steel reinforcement mesh 3, and a third steel reinforcement mesh 4 arranged at intervals along the horizontal direction. The first steel reinforcement mesh 2 and the second steel reinforcement mesh 3 form an insulation chamber for placing the insulation board 1, and the second steel reinforcement mesh 3 and the third steel reinforcement mesh 4 form a casting chamber. The tie bars pass through the insulation chamber and the casting chamber and are respectively tied to the tie bars of the first steel reinforcement mesh 2, the second steel reinforcement mesh 3, and the third steel reinforcement mesh 4.
[0031] like Figure 1 As shown, the first steel mesh frame 2 is connected to the second steel mesh frame 3 by means of multiple intersecting oblique steel bars 11. The first steel mesh frame 2 and the second steel mesh frame 3 clamp and fix the insulation board 1 by means of the oblique steel bars 11. The oblique steel bars 11 can fix the insulation board 1 and at the same time prevent the first steel mesh frame 2 and the second steel mesh frame 3 from excessively squeezing the insulation board 1.
[0032] like Figure 1 As shown, plastic caps 12 are provided at the abutting ends of the fixing part 5 and the template 14, and at the abutting ends of the insertion part 6 and the template 14, respectively. The two ends of the tie bar abut against the template 14 with the help of the plastic caps 12. By providing plastic caps 12, the wall surface is flat, which makes the final wall surface flat and less prone to cracks.
