Description

Technical Field

[0001] This utility model relates to the field of thermal insulation composite wall technology, and in particular to a pull tab connector and a thermal insulation composite wall. Background Technology

[0002] In existing technologies, integrating insulation materials with precast composite walls can form precast insulated composite wall panels. The final insulated composite wall is then formed on-site by pouring concrete into the cavity between the precast insulated composite wall panel and the aluminum formwork. During concrete pouring, tie rods are needed to connect the precast composite wall and the aluminum formwork to maintain the cavity width and prevent the aluminum formwork from bulging under concrete pressure.

[0003] The invention disclosed in CN118498575A presents a prefabricated insulated composite wall panel and a construction method for the insulated composite wall. The prefabricated insulated composite wall panel includes an insulation panel body, a space frame, and embedded components. The space frame is located within the insulation panel body or penetrates the side wall of the insulation panel body. The embedded components include hangers, fasteners, pull tab joints, and pull tabs. The hangers are located on the upper part of the space frame, and the fasteners are located on the lower part of the space frame, with the fasteners cooperating with adjacent hangers. One end of the pull tab joint is connected to the space frame, and the other end penetrates the insulation panel body and is movably connected to the pull tab. However, the pull tab type is not suitable for the production of FRP (glass fiber reinforced plastic) materials with low shear strength, low thermal conductivity, and low production cost. There is a risk of thermal bridging through the pull tabs, which may adversely affect the insulation performance of the insulated composite wall. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a pull tab connector and an insulated composite wall, which enables the use of materials with low thermal conductivity and low cost, avoids the risk of thermal bridging, and improves the thermal insulation performance of the insulated composite wall.

[0005] To achieve the above objectives, this utility model provides a pull tab connector, including a pull tab joint and a single-ended pull tab that can be connected together. The pull tab joint is a rectangular piece. A through hole is formed at one end of the pull tab joint away from the single-ended pull tab. A strip groove is formed at the other end of the pull tab joint near the single-ended pull tab. A protrusion is formed at the end of the single-ended pull tab near the pull tab joint. The protrusion can be hooked with the strip groove. A mounting hole is formed at the end of the single-ended pull tab away from the pull tab joint.

[0006] In this invention, the through hole on the pull tab joint can be used to pass through reinforcing bars, and the pull tab joint can be conveniently fixed by fixing the reinforcing bars at a preset position in the insulated composite wall. The pull tab joint is designed as a rectangular plate, so that when subjected to the tensile force of a single pull tab, the pull tab joint does not need to withstand additional shearing force. Its simple shape facilitates processing and allows for a wider selection of materials, enabling the use of materials with low shear strength and low thermal conductivity, such as FRP. Furthermore, the relatively low cost of FRP allows the pull tab joint to balance the requirements of low thermal conductivity to avoid thermal bridging and low production costs. By creating a gap hook between the slot and the protrusion, the single pull tab has a certain amount of movable space, allowing the mounting hole of the single pull tab to be easily adapted to the aluminum mold.

[0007] Optionally, the pull tab connector is a rectangular sheet structure arranged horizontally, the single-head pull tab is a spring structure arranged vertically, and the protrusion is located at the bottom of the pull tab connector and protrudes downward.

[0008] In this invention, the pull tab connector is arranged horizontally and the single-head pull tab is arranged vertically. When the protrusion is assembled into the strip groove, the single-head pull tab can be stably assembled onto the pull tab connector by the weight of the single-head pull tab. There is no need to design an additional structure to restrict the lateral dislodgement of the single-head pull tab, which further reduces the cost.

[0009] Optionally, a groove is provided on the side of the through hole near the strip groove, and the groove can be used to thread binding wire.

[0010] In this utility model, when a reinforcing bar is inserted inside, the tie wire can be inserted into the groove to fix the pull tab joint to the reinforcing bar, thereby achieving a more stable installation of the pull tab joint.

[0011] Optionally, the single-head pull tab has a "7" shaped structure, and the center of the mounting hole is on the same horizontal plane as the pull tab connector.

[0012] In this utility model, the assembly of the "7"-shaped single-ended pull tab and the pull tab connector is more convenient. The protrusion at the head of the single-ended pull tab can better receive the weight of the single-ended pull tab, so as to ensure a stable fit between the single-ended pull tab and the pull tab connector. The mounting hole is set at the same horizontal plane as the pull tab connector, so that the assembly position of the single-ended pull tab and the aluminum mold is more reliable.

[0013] Optionally, the material of the pull tab connector is glass fiber reinforced plastic.

[0014] In this invention, glass fiber reinforced plastic has good tensile properties and low thermal conductivity. Although its shear resistance and processing convenience are insufficient, it can be adapted to the rectangular shape of the pull tab joint in this application. While avoiding the risk of thermal bridging, it can effectively improve the production yield of the pull tab joint and reduce production costs.

[0015] Optionally, the material of the single-head pull tab is 50 manganese steel.

[0016] In this invention, the single-ended pull tab made of 50 manganese steel has the characteristic of being able to withstand high stress and can meet the assembly requirements of the single-ended pull tab and pull tab joint of the "7" shaped structure.

[0017] This utility model also provides an insulated composite wall, including an insulation board, a truss disposed on the insulation board, and the aforementioned tie plate connector. The truss is provided with a steel mesh, and steel bars can be inserted through the through holes. The steel bars can be tied to the steel mesh.

[0018] In this utility model, the steel bars with fixed pull tab joints can be tied to the preset positions on the steel mesh of the thermal insulation composite wall according to the design, or the pull tab joints can be directly installed on the steel mesh, which can achieve a stable and flexible installation effect of the pull tab joints.

[0019] Optionally, the insulation board is provided with a hanging member at the top and a fixing member at the bottom, and the fixing member can be connected with the hanging member of the adjacent insulation composite wall.

[0020] In this utility model, the upper and lower thermal insulation composite walls can be fixedly assembled by the cooperation of the hanging and fixing parts of the adjacent upper and lower thermal insulation composite walls.

[0021] Beneficial effects:

[0022] In this invention, the through hole on the pull tab joint can be used to pass through reinforcing bars, and the pull tab joint can be conveniently fixed by fixing the reinforcing bars at a preset position in the insulated composite wall. The pull tab joint is designed as a rectangular plate, so that when subjected to the tensile force of a single pull tab, the pull tab joint does not need to withstand additional shearing force. Its simple shape facilitates processing and allows for a wider selection of materials, enabling the use of materials with low shear strength and low thermal conductivity, such as glass fiber reinforced plastic. Furthermore, the relatively low cost of glass fiber reinforced plastic allows the pull tab joint to balance the requirements of low thermal conductivity to avoid thermal bridging and low production costs. By creating a gap hook between the slot and the protrusion, the single pull tab has a certain amount of movable space, allowing the mounting hole of the single pull tab to be easily adapted to the aluminum mold.

[0031] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the implementation methods and with reference to the accompanying drawings. Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0035] See Figures 1 to 3 According to an embodiment of the present invention, a pull tab connector includes a pull tab joint 1 and a single-ended pull tab 2 that can be connected together. The pull tab joint 1 is a rectangular piece. A through hole 11 is provided at one end of the pull tab joint 1 away from the single-ended pull tab 2. A strip groove 12 is provided at the other end of the pull tab joint 1 near the single-ended pull tab 2. A protrusion 21 is formed at the end of the single-ended pull tab 2 near the pull tab joint 1. The protrusion 21 can be interlocked with the strip groove 12. An installation hole 22 is provided at the end of the single-ended pull tab 2 away from the pull tab joint 1.

[0036] In this invention, the through hole 11 on the pull tab joint 1 can be used to pass through the reinforcing bar 3, and the pull tab joint 1 can be conveniently fixed by fixing the reinforcing bar 3 at a preset position in the thermal insulation composite wall. The pull tab joint 1 is designed as a rectangular plate, so that when subjected to the tensile force of the single-ended pull tab 2, the pull tab joint 1 does not need to bear additional shear force. Its simple shape facilitates processing, allowing for more material choices. It can be produced using materials with low shear strength and low thermal conductivity, such as FRP. Furthermore, since FRP material is relatively inexpensive, the pull tab joint 1 can balance the requirements of low thermal conductivity to avoid thermal bridging risk and low production cost. By achieving a gap hook connection between the strip groove 12 and the protrusion 21, the single-ended pull tab 2 has a certain amount of movable space, improving the installation error tolerance and allowing the mounting hole 22 of the single-ended pull tab 2 to be smoothly adapted to the aluminum mold.

[0037] Specifically, in actual production, stainless steel or other materials can be selected for the pull tab connector 1. However, compared with the pull tab connector 1 made of FRP material, stainless steel has a higher cost and higher thermal conductivity, which does not meet the needs of actual production. If other pull tab connectors 1 made of other lower cost materials are used, such as the Z-type pull tab in the prior art, it is difficult to ensure both low thermal conductivity and shear resistance at the same time. Moreover, the production process is more complicated and the cost is higher. The rectangular plate-shaped FRP pull tab connector 1 used in this application can meet the requirements of structure and cost.

[0038] See Figure 2 and Figure 3In some embodiments of this utility model, the pull tab connector 1 is a rectangular sheet structure arranged horizontally, the single-head pull tab 2 is a spring structure arranged vertically, and the protrusion 21 is disposed at the bottom of the pull tab connector 1 and protrudes downward.

[0039] In this invention, the pull tab connector 1 is arranged horizontally and the single-head pull tab 2 is arranged vertically. When the protrusion 21 is assembled into the strip groove 12, the single-head pull tab 2 can be stably assembled onto the pull tab connector 1 by the gravity of the single-head pull tab 2. There is no need to design an additional structure to restrict the lateral dislodgement of the single-head pull tab 2, which further reduces the cost.

[0040] See Figure 2 In some embodiments of this utility model, a groove 13 is provided on the side of the through hole 11 near the strip groove 12, and the groove 13 can be used to thread binding wire.

[0041] In this utility model, when the inner reinforcing bar 3 is inserted, the tie wire is inserted in the groove 13 to fix the pull tab joint 1 on the reinforcing bar 3, thereby achieving a more stable installation of the pull tab joint 1.

[0042] See Figure 3 and Figure 5 In some embodiments of this utility model, the single-head pull tab 2 has a "7" shaped structure, and the center of the mounting hole 22 is on the same horizontal plane as the pull tab connector 1.

[0043] In this utility model, the assembly of the "7"-shaped single-head pull tab 2 and the pull tab connector 1 is more convenient. The protrusion 21 at the head end of the single-head pull tab 2 can better receive the weight of the single-head pull tab 2, so as to ensure a stable fit between the single-head pull tab 2 and the pull tab connector 1. The mounting hole 22 is set at the same horizontal plane as the pull tab connector 1, so that the assembly position of the single-head pull tab 2 and the aluminum mold is more reliable.

[0044] In some embodiments of this utility model, the material of the pull tab connector 1 is glass fiber reinforced plastic.

[0045] In this invention, glass fiber reinforced plastic has good tensile properties and low thermal conductivity. Although its shear resistance and processing convenience are insufficient, it can be adapted to the rectangular shape of the pull tab joint 1 in this application. While avoiding the risk of thermal bridging, it can effectively improve the production yield of the pull tab joint and reduce production costs.

[0046] In some embodiments of this utility model, the material of the single-head pull tab 2 is 50 manganese steel.

[0047] In this utility model, the single-headed pull tab 2 made of 50 manganese steel has the characteristic of being able to withstand high stress and can meet the assembly requirements of the "7"-shaped single-headed pull tab 2 and the pull tab joint 1.

[0048] See Figure 4 and Figure 5 According to an embodiment of the present utility model, an insulated composite wall includes an insulation board 4, a truss 5 disposed on the insulation board 4, and the aforementioned tie plate connector. The truss 5 is provided with a steel mesh, and a steel bar 3 can be inserted through the through hole 11. The steel bar 3 can be tied to the steel mesh.

[0049] In this utility model, the steel bar 3 with the pull tab joint 1 can be tied to a preset position on the steel mesh of the thermal insulation composite wall according to the design, or the pull tab joint 1 can be directly installed on the steel mesh, so as to achieve a stable and flexible installation effect of the pull tab joint 1.

[0050] See Figure 4 In some embodiments of this utility model, the upper part of the insulation board 4 is provided with a hanging member 6 and the lower part is provided with a fixing member 7. The fixing member 7 can be connected with the hanging member 6 of the adjacent insulation composite wall.

[0051] In this utility model, the upper insulation composite wall and the lower insulation composite wall can be fixedly assembled by the cooperation of the hanging parts 6 and the fixing parts 7 of the adjacent upper and lower insulation composite walls.

[0052] Specifically, the lifting component 6 consists of a lifting plate and anchor bars. The lifting plate is connected to the truss 5 installed inside the insulation panel 4 via the anchor bars. The lifting component 6 has lifting holes and bolt holes. The lifting holes are relatively large and can be used to pass through the lifting hooks. After the lifting is completed, the lifting component 6 is connected to the fixing component 7. Both the lifting holes and bolt holes can be used for two bolts of the fixing component 7 to pass through. It is tightened with washers and nuts. The lifting plate is tied to the truss 5 via the anchor bars.

[0053] The fastener 7 is a steel plate with two bolts embedded in it. These bolts pass through the lifting holes and screw holes of the hanger 6 for fastening, so that the upper layer of insulated composite wall is fixed to the lower layer of ground or the lower layer of insulated composite wall after hoisting. Anchor steel bars 3 are welded to the bottom of the fastener 7 and are tied to the truss 5 set inside the insulation board 4 through the anchor steel bars 3.

[0054] The pull tab joint 1 and single-head pull tab 2 in this utility model are improvements on the joint and pull tab in the invention patent with publication number CN118498575B. Therefore, except for the structure and installation of the pull tab joint 1 and single-head pull tab 2, the structure of the insulation board 4 in the insulation composite wall, the structure of the truss 5, the hanger 6 and the fixing member 7 set on the insulation board 4, and the construction method of the insulation composite wall are all consistent with the contents described in the invention patent with publication number CN118498575B, the insulation composite wall and the construction method of the insulation composite wall.

[0055] During installation, a reinforcing bar 3 is inserted into the through hole 11 of the pull tab connector 1, and a binding wire is inserted into the groove 13 to tie and fix the pull tab connector 1 to the reinforcing bar 3. The reinforcing bar 3 with the pull tab connector 1 fixed thereon can be tied to the preset position of the reinforcing mesh of the thermal insulation composite wall according to the design, or the pull tab connector 1 can be directly installed on the reinforcing mesh. One end of the strip groove 12 of the pull tab connector 1 extends out of the thermal insulation composite wall, and the protrusion 21 of the single-head pull tab 2 is assembled into the strip groove 12, so that the mounting hole 22 of the single-head pull tab 2 and the pull tab connector 1 are at the same horizontal height. At the same time, the mounting hole 22 is adapted to connect with the aluminum formwork to realize the installation and fixation of the thermal insulation composite wall and the aluminum formwork.

[0056] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model.
