Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and in particular relates to a self-locking, non-removable thermal insulation formwork anchor and its construction method. Background Technology

[0002] With the continuous development of prefabricated buildings, more and more buildings are adopting integrated insulation and structural construction methods, and non-removable insulation formwork is widely used. In the current construction process, after installing the non-removable insulation formwork and inserting the anchors, workers need to use tie wire to fix the anchors to the already tied wall reinforcement on the other side of the wall. At this time, because the reinforcement has already been tied, the working area is limited, and there are many anchors, making the tying work time-consuming and labor-intensive. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a self-locking, non-removable thermal insulation formwork anchor and construction method, which effectively solves the technical problems of cumbersome, time-consuming and labor-intensive fixing methods of non-removable thermal insulation formwork anchors and overcomes the shortcomings of the prior art.

[0004] The technical solution adopted in this invention is: a self-locking, non-removable thermal insulation template anchor, comprising:

[0005] The disc cover has a sleeve on one side;

[0006] The nail head is located at the end of the sleeve away from the disc cover;

[0007] An elastic connector is disposed inside the sleeve, with one end connected to the disc cover and the other end connected to the nail head.

[0008] Furthermore, the nail head is provided with a slot, which can engage with the elastic connector.

[0009] Furthermore, the elastic connector includes a spring and a steel wire rope connected together, with the end of the spring away from the steel wire rope connected to the disc cover, and the end of the steel wire rope away from the spring connected to the nail head.

[0010] Furthermore, a slider is provided between the spring and the wire rope, and the slider is slidably connected to the sleeve.

[0011] Furthermore, a fixed base is provided at the connection between the disc cover and the spring.

[0012] Furthermore, the number of steel wire ropes is set to multiple.

[0013] Furthermore, the nail head is configured to be tapered.

[0014] Furthermore, the outer wall of the sleeve is provided with an anchoring part, one side of which is connected to the outer wall of the sleeve, and the other side extends outward along the radial direction of the sleeve.

[0015] Furthermore, the anchoring part is provided in multiple parts, which are evenly arranged along the circumference of the sleeve.

[0016] The present invention also provides a construction method using a self-locking, non-removable thermal insulation formwork anchor as described above, comprising the following steps:

[0017] Install the non-removable insulation template;

[0018] Pass the sleeve through the non-removable insulation template;

[0019] Pull out the nail head, bringing out the elastic connector, and after passing around the wall reinforcement, fix the nail head to the elastic connector.

[0020] The advantages and positive effects of this invention are:

[0021] By stretching the nail head around the wall reinforcement, the wire rope is inserted into the groove of the nail head, and the anchor fixing work is quickly completed. This simplifies the operation steps, has a simple structure, is easy to operate, saves time and labor, improves the construction efficiency of workers, and helps to shorten the construction period.

In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of the present invention provides a self-locking, non-removable thermal insulation template anchor, comprising a cover 1, a sleeve 2, a nail head 7, and an elastic connector. A sleeve 2 is provided on one side of the cover 1, with one end of the sleeve 2 fixedly connected to the middle of the cover 1. The nail head 7 is located at the end of the sleeve 2 furthest from the cover 1. The elastic connector is located inside the sleeve 2, with one end connected to the cover 1 and the other end connected to the nail head 7. The elastic connector engages the nail head 7 at the end of the sleeve 2 furthest from the cover 1; pulling the nail head 7 extends the elastic connector. After inserting the sleeve 2 into the non-removable thermal insulation template 9, pulling out the nail head 7 brings out the elastic connector, passes it around the wall reinforcement 10, and then fixing the nail head 7 to the elastic connector, thus fixing the entire anchor. The structure is simple, the operation is convenient, and construction efficiency is improved.

[0031] Specifically, in order to facilitate the fixing of the nail head 7 and the elastic connector, the nail head 7 is provided with a slot 8, which can engage with the elastic connector.

[0032] Specifically, the elastic connector includes a spring 4 and a steel wire rope 6. The end of the spring 4 away from the steel wire rope 6 is fixedly connected to the cover 1, and the end of the steel wire rope 6 away from the spring 4 is fixedly connected to the nail head 7. The spring 4 ensures the elasticity of the entire elastic connector, allowing the nail head 7 to be pulled out freely. The steel wire rope 6 ensures the rigidity of the elastic connector, ensuring the reliability of the connection.

[0033] Preferably, a slider 5 is provided between the spring 4 and the wire rope 6, and the slider 5 is slidably connected to the sleeve 2. When the nail head 7 is pulled, the slider 5 slides along the sleeve 2, which facilitates the free stretching of the spring 4. The side of the slider 5 closest to the spring 4 is fixedly connected to the spring 4 and does not contact the inner wall of the sleeve 2. The side of the slider 5 closest to the wire rope 6 is fixedly connected to the wire rope 6, and is slidably connected to the inner wall of the sleeve 2 in the circumferential direction. When the nail head 7 is pulled, the slider 5 slides along the inner wall of the sleeve 2, stretching the spring 4.

[0034] Preferably, a fixing base 3 is provided at the connection between the disc cover 1 and the spring 4. One end of the fixing base 3 is fixedly connected to the disc cover 1, and the other end is fixedly connected to the end of the spring 4. The shape of the fixing base 3 is not limited.

[0035] Preferably, the number of steel wire ropes 6 is set to multiple. By setting multiple steel wire ropes 6, the firmness of the anchor connection is ensured.

[0036] Specifically, in order to facilitate the passage through the non-removable insulation template 9, the nail head 7 is set to be tapered.

[0037] Specifically, the outer wall of the sleeve 2 is provided with an anchoring part, one side of which is connected to the outer wall, and the other side extends outward along the radial direction of the sleeve 2. The anchoring part can enhance the anchoring effect of the anchor. There are multiple anchoring parts, which are evenly arranged along the circumference of the sleeve 2, effectively strengthening the connection strength between the non-removable thermal insulation formwork 9 and the concrete layer.

[0038] Example: A self-locking, non-removable thermal insulation template anchor includes a cover 1, a sleeve 2, a nail head 7, and an elastic connector. A sleeve 2 is provided on one side of the cover 1, with one end of the sleeve 2 fixedly connected to the middle of the cover 1. The nail head 7 is located at the end of the sleeve 2 away from the cover 1. The elastic connector is located inside the sleeve 2, with one end connected to the cover 1 and the other end connected to the nail head 7. The nail head 7 has a slot 8. The elastic connector includes a spring 4 and a steel wire rope 6 connected together. The end of the spring 4 away from the steel wire rope 6 is connected to the cover 1, and the end of the steel wire rope 6 away from the spring 4 is connected to the nail head 7. A slider 5 is provided between the spring 4 and the steel wire rope 6, and the slider 5 is slidably connected to the sleeve 2. The side of the slider 5 closest to the spring 4 is fixedly connected to the spring 4 and does not contact the inner wall of the sleeve 2. The side of the slider 5 closest to the steel wire rope 6 is fixedly connected to the steel wire rope 6 and slidably connected to the inner wall of the sleeve 2 circumferentially. A fixed base 3 is provided at the connection between the cover 1 and the spring 4. One end of the fixed base 3 is fixedly connected to the cover 1, and the other end is fixedly connected to the end of the spring 4. Two steel wire ropes 6 are provided. The nail head 7 is tapered. Four anchoring parts are provided on the outer wall of the sleeve 2, evenly distributed along the outer circumference of the sleeve. One side of the anchoring part is connected to the outer wall, and the other side extends outward radially along the sleeve 2.

[0039] like Figure 4As shown, a construction method using a self-locking, non-removable thermal insulation formwork anchor as described above includes the following steps:

[0040] S1. Install the non-removable insulation template 9;

[0041] S2. Pass the sleeve 2 through the non-removable insulation template 9;

[0042] S3. The worker moves to the other side of the wall, pulls out the nail head 7, bringing out the steel wire rope 6, and after passing it around the wall reinforcement 10, aligns the nail head 7 slot 8 with the steel wire rope 6 and presses it down to fix it. Under the contraction force of the internal spring 4, the steel wire rope 6 can be firmly locked in the nail head 7 slot 8;

[0043] S4. Repeat the previous step until all anchors on the wall are fixed.

[0044] S5. Cast the concrete for the wall by closing the mold.

[0045] The advantages and positive effects of this invention are:

[0046] By stretching the nail head around the wall reinforcement, the wire rope is inserted into the groove of the nail head, and the anchor fixing work is quickly completed. This simplifies the operation steps, has a simple structure, is easy to operate, saves time and labor, improves the construction efficiency of workers, and helps to shorten the construction period.
