Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation concrete blocks, in particular to a thermal insulation concrete block connecting nail and a thermal insulation concrete block. Background Art

[0002] The existing thermal insulation concrete blocks are composed of concrete blocks and foam blocks. During manufacturing, the foam blocks are placed in a forming mold, and then concrete is injected into the forming mold. The foam blocks and the concrete blocks are connected by a dovetail groove structure. At the same time, connecting nails are driven into the sides of the foam blocks, part of which is located in the foam block, and the other part of which is located in the concrete block, so that the connection between the concrete block and the foam block is further strengthened by the connecting nails.

[0003] During production, the connecting nails are first driven into the foam blocks and then put into the forming mold together with the foam blocks. Since the production site of the foam blocks and the production site of the thermal insulation blocks may not be in the same place, the pre-produced foam blocks cannot be neatly stacked due to the driving of the connecting nails, which protrude from the surface of the foam blocks, affecting the transportation of the foam blocks. Summary of the invention

[0005] The technical solution of the utility model is achieved in this way:

[0006] A heat-insulating concrete block connecting nail comprises a connecting nail body, wherein the connecting nail body is provided with a plug-in hole, the plug-in hole is arranged through the rear end of the connecting nail body, a movable nail is plugged into the plug-in hole, the movable nail is movably connected to the plug-in hole, and a limiting plate is provided at the rear end of the movable nail.

[0007] The utility model is further configured such that the diameter of the limiting plate is greater than the diameter of the connecting nail body.

[0008] The utility model is further configured that the front end of the connecting nail body is provided with an anti-drop barb.

[0009] The utility model is further configured to include a limiting rope, one end of which is connected to the limiting plate, and the other end of which is fixedly connected to the connecting nail body; when the limiting rope is straightened, the movable nail remains inserted in the plug-in hole.

[0010] The utility model is further configured that the front end of the connecting nail body is conical.

[0011] A thermal insulation concrete block comprises a foam block, wherein concrete blocks are respectively arranged on the left and right sides of the foam block, the left and right side surfaces of the foam block are respectively provided with the above-mentioned connecting nails, the connecting nail body is inserted into the foam block, and the movable nail is located in the concrete block.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0013] The thermal insulation concrete block connecting nail and the thermal insulation concrete block provided by the utility model have a connecting nail body inserted into a foam block, and a movable nail inserted into the connecting nail body. In this way, when the foam blocks are stacked, it is equivalent to that the connecting nail body and the movable nail are both in a state of being inserted into the foam blocks, which will not affect the neat stacking of the foam blocks; when the foam blocks are placed in a forming mold for use, the movable nail can be pulled out and then concrete can be poured.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] For reference Figure 1-6 The utility model is described as follows:

[0023] Embodiment 1: A thermal insulation concrete block comprises a foam block 7 (the foam block 7 usually has good thermal insulation performance, and being arranged in the middle can effectively reduce the heat transfer and improve the thermal insulation effect of the wall), concrete blocks 8 are respectively arranged on the left and right sides of the foam block 7, and connecting nails are respectively arranged on the left and right side surfaces of the foam block 7, and the connecting nail comprises a connecting nail body 1, and a plug-in hole 2 is arranged on the connecting nail body 1, and the plug-in hole 2 runs through the rear end of the connecting nail body 1 to provide a movable space and installation position for a movable nail 3, and a movable nail 3 is inserted in the plug-in hole 2, and the movable nail 3 is movably connected to the plug-in hole 2, and a limiting plate 4 is provided at the rear end of the movable nail 3, and the diameter of the limiting plate 4 is larger than the diameter of the connecting nail body 1, and the connecting nail body 1 is inserted into the foam block 7 to play a role in preliminarily fixing the foam block 7 and the concrete block 8, and the rear end of the movable nail 3 is located in the concrete block 8, and the front end of the movable nail 3 is inserted in the plug-in hole 2. When the movable nail 3 is not in use, it is fully inserted into the plug hole 2, saving space and not affecting the neat stacking of the foam blocks 7. When in use, the movable nail 3 is pulled out to enhance the stability and firmness of the connection. The diameter of the limit plate 4 is larger than the diameter of the connecting nail body 1, which can prevent the movable nail 3 from being over-inserted into the plug hole 2. At the same time, after the movable nail 3 is pulled out, it is limited to move toward the connecting nail body 1 to ensure that it plays a fixing role in the concrete block 8.

[0024] The movable nail 3 does not protrude when not in use, which is convenient for transportation and construction operation; it can be pulled out when the connection needs to be strengthened, which increases the flexibility of construction.

[0025] The front end of the connecting nail body 1 is conical. The conical design makes it easier for the connecting nail body 1 to penetrate the foam block 7 when inserted, reducing the resistance of insertion. The guiding effect helps to maintain the correct direction during the insertion process and improve the accuracy and efficiency of installation. The front end of the connecting nail body 1 is provided with an anti-detachment barb 5. Once the connecting nail body 1 is inserted into the foam block 7, the anti-detachment barb 5 can prevent the connecting nail body 1 from being easily pulled out, thereby increasing the stability and reliability of the connection. When subjected to an outward pulling force, the anti-detachment barb 5 will generate greater resistance with the inside of the foam block 7, thereby improving the pull-out resistance of the entire connection structure.

[0026] It also includes a restriction rope 6, one end of which is connected to the limit plate 4, and the other end of which is fixedly connected to the connecting nail body 1; when the restriction rope 6 is straightened, the movable nail 3 remains inserted in the plug hole 2, and this arrangement can ensure that the movable nail 3 will not be pulled out of the plug hole 2. When the movable nail 3 is pulled out for use, the restriction rope 6 can ensure that the movable nail 3 will not be accidentally pulled out of the plug hole 2, thereby avoiding possible unstable connection or construction errors.

[0027] The straightening of the limiting rope 6 limits the movable nail 3 from being pulled outward, so that the movable nail 3 is stably located in the insertion hole 2, and the movable nail 3 will not be accidentally pulled out or partially extended.

[0028] The connecting nail body 1 and the movable nail 3 are made of plastic or stainless steel.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
