Description

Technical Field

[0001] The utility model relates to the field of expansion strengthening belts, in particular to a reusable expansion strengthening belt steel wire mesh support mechanism. Background Technique

[0002] Expansion strengthening belts are used in construction projects to enhance the crack resistance and waterproof performance of concrete structures. Especially in structures such as building basements that require high-density concrete, they can effectively prevent groundwater from seeping into the indoor space. Currently, during the construction of expansion strengthening belts, it is usually necessary to use construction steel wire meshes to isolate both sides, which can enhance the tensile strength of local areas and prevent cracks caused by stress concentration. At the same time, it can avoid the displacement of the expansion strengthening belt due to the flow influence between concretes.

[0003] To ensure that the steel wire mesh does not shift or topple during the concrete pouring process, the traditional method is to add additional steel bars outside the design to form a support structure. However, this method not only increases the construction cost, but also these steel bars used for support still remain in the structure after the concrete pouring is completed and cannot be recycled and reused, further increasing the cost burden of the construction unit. In addition, due to the obstruction of the upper steel bar mesh of the floor slab, the traditional support structure is difficult to play an effective role. To solve the above problems, it is necessary to develop a special reusable expansion strengthening belt steel wire mesh support mechanism and its support method to reduce the construction cost and improve the resource utilization rate.

DETAILED DESCRIPTION

[0034] Example 1

[0035] As Figure 1-13 shown, a reusable expansion strengthening belt wire mesh support mechanism includes a plurality of telescopic expansion components 1 and node reinforcement components 2. The telescopic expansion components 1 and the node reinforcement components 2 are arranged alternately at intervals, and the two are connected by a connecting block 6. On both sides of the node reinforcement component 2, or on both sides of the node reinforcement component 2 and the telescopic expansion component 1, telescopic hooks 4 are arranged through a connecting rod 3 for fixing the support device on the upper layer of the steel mesh.

[0036] It should be noted that the number of the telescopic expansion components 1 and the node reinforcement components 2, and whether the telescopic expansion component 1 or the node reinforcement component 2 is arranged on the outermost side can be determined according to the actual situation. In this embodiment, the number of the telescopic expansion components 1 is two, and the number of the node reinforcement components 2 is three. During use, the telescopic expansion components 1 and the node reinforcement components 2 are inserted into the corresponding grids of the upper layer of the steel mesh, and are erected on the upper layer of the steel mesh through the connecting rod 3, and then the telescopic hooks 4 can be used to fix them on the upper layer of the steel mesh.

[0037] The telescopic expansion component 1 includes a first outer sleeve rod 100. A telescopic vertical support rod 101 is telescopically inserted into the first outer sleeve rod 100. Both ends of the first outer sleeve rod 100 are open, facilitating the telescopic vertical support rod 101 to penetrate and be inserted therein. A plurality of cross support components 102 that can expand to both sides are arranged below the telescopic vertical support rod 101. The number of the cross support components 102 is determined according to the length of the telescopic vertical support rod 101 passing through the upper layer of the steel mesh. In this embodiment, the number of the cross support components 102 is two.

[0038] When the cross support components 102 of all the telescopic expansion components 1 penetrate out of the first outer sleeve rod 100, they expand to both sides below the upper layer of the steel mesh and cooperate with the telescopic vertical support rod 101 to form a grid-like support structure. The node reinforcement component 2 is located at the docking position of adjacent cross support components 102 to provide support for them.

[0039] Designed in this way, while avoiding the upper layer of the steel mesh, an effective grid-like support structure can be formed for the wire mesh, which can effectively avoid the problems of wire mesh deviation or tipping. At the same time, by lifting upwards, the support device is pulled out from the poured concrete, achieving the effect of repeated use and effectively saving the construction cost.

[0040] In a preferred embodiment, the cross brace assembly 102 includes a first telescopic cavity 1020 formed in the telescopic vertical brace 101, and two first receiving cavities 1021 respectively formed on both sides of the telescopic vertical brace 101. The first telescopic cavity 1020 is connected to the two first receiving cavities 1021 through a first communication groove 1022. A cross brace 1023 is hingedly provided at the top of the first receiving cavity 1021. The size of the first receiving cavity 1021 is adapted to the size of the cross brace 1023, facilitating the cross brace 1023 to be retractable therein. A first support rod 1024 is provided in the first telescopic cavity 1020. A first lifting shaft 1025 is slidably sleeved outside the first support rod 1024. A first strut 1026 with both ends hinged is provided between the first lifting shaft 1025 and the two cross braces 1023 through the first communication groove 1022. A first spring (1027) is sleeved outside the first support rod 1024. The first spring (1027) is located between the first lifting shaft 1025 and the inner bottom wall of the first telescopic cavity 1020.

[0041] With such a design, when the cross brace 1023 loses the restriction of the external first outer sleeve rod 100, it can be automatically sprung open by the tension of the first spring (1027), thereby achieving the effect of cross bracing. At the same time, when lifting, when the cross brace 1023 is resisted from above, it can be contracted by compressing the first spring (1027), so as to avoid the upper layer of steel mesh and lift it out.

[0042] In a preferred embodiment, the node reinforcement assembly 2 includes a second outer sleeve rod 200. A node reinforcement rod 201 is telescopically inserted into the second outer sleeve rod 200. Both ends of the second outer sleeve rod 200 are open, facilitating the node reinforcement rod 201 to be inserted therethrough.

[0043] The connecting block 6 is fixedly provided between the first outer sleeve rod 100 and the second outer sleeve rod 200, thereby connecting the two into one body. When the bottom of the node reinforcement rod 201 passes through the second outer sleeve rod 200, it is located at the rear side of the docking portion of the adjacent cross brace assemblies 102.

[0044] With such a design, the node reinforcement rod 201 can provide support for the docking portion of the two adjacent cross braces 1023 on the left and right, further improving its overall support.

[0045] In a preferred embodiment, connection cross beams 7 are provided at the tops of both the telescopic vertical braces 101 and the node reinforcement rods 201 for connecting all the telescopic vertical braces 101 and all the node reinforcement rods 201. A lifting lug 8 is further provided at the top of the connection cross beam 7, facilitating controlling the lifting of all the telescopic vertical braces 101 or all the node reinforcement rods 201 through the corresponding connection cross beam 7. The lifting lug 8 facilitates lifting the device out of the concrete.

[0046] Limit blocks 103 are provided at the bottom ends of the node reinforcement rod 201 and the telescopic vertical support rod 101, which can prevent the node reinforcement rod 201 and the telescopic vertical support rod 101 from being directly pulled out of the first outer sleeve rod 100 or the second outer sleeve rod 200.

[0047] In a preferred embodiment, the telescopic hook 4 includes a connection seat 401 provided at the end of the connecting rod 3. An adjustment cavity 402 with an open front end is provided in the connection seat 401. A hook body 404 inserted from the opening is telescopically provided in the adjustment cavity 402. An adjustment mechanism for adjusting the telescopic movement of the hook body 404 is further provided at the top of the connection seat 401.

[0048] It should be noted that the hook body 404 meets the requirement of hooking the steel bars of the upper steel bar mesh.

[0049] Among them, the adjustment mechanism includes an adjustment groove 403 provided at the top of the connection seat 401 and communicating with the adjustment cavity 402. A threaded plate 407 passing through the adjustment groove 403 is provided at the top of the end of the hook body 404. Two symmetrically arranged baffles 408 are fixedly provided at the top of the connection seat 401. An adjustment screw 405 is rotatably provided between the two baffles 408. The adjustment screw 405 is rotatably provided between the two baffles 408 through bearings. The threaded plate 407 is threadedly sleeved outside the adjustment screw 405. One end of the adjustment screw 405 penetrates through the baffle 408 and is connected with an adjustment handle 406.

[0050] With such a design, the adjustment screw 405 can be rotated by rotating the adjustment handle 406, and then the hook body 404 can be driven to expand and contract through the threaded plate 407, so as to achieve the effect of tightly hooking the steel bars of the upper steel bar mesh. Furthermore, the effect of fixing the device on the upper steel bar mesh can be achieved by the method of tightly hooking both ends simultaneously.

[0051] In the preferred embodiment, the node reinforcement assembly 2 also includes a retractable diagonal brace 203 provided below the node reinforcement rod 201. The retractable diagonal brace 203 includes a second telescopic cavity 2030 provided below the node reinforcement rod 201 and a second accommodating cavity 2031 provided on the rear side of the node reinforcement rod 201. The second telescopic cavity 2030 is connected to the second accommodating cavity 2031 through a second connecting groove 2032. The top of the second accommodating cavity 2031 is hinged with a diagonal brace 2033. The size of the second accommodating cavity 2031 is consistent with the size of the diagonal brace 2033. The size is adapted to facilitate the accommodation of the diagonal support rod 2033 therein. A second support rod 2034 is provided in the second telescopic chamber 2030. The outside of the second support rod 2034 is provided with a second lifting shaft 2035. A second top support rod 2037 hinged at both ends is provided between the second lifting shaft 2035 and the diagonal support rod 2033 through a second connecting groove 2032. The outside of the second support rod 2034 is provided with a second spring 2036. The second spring 2036 is located between the second lifting shaft 2035 and the inner bottom wall of the second telescopic chamber 2030.

[0052] The design and working principle of this structure are the same as those of the cross brace assembly 102 , and therefore will not be described in detail here.

[0053] In order to provide support for the retractable diagonal brace 203, an interference support assembly 5 for providing support for the retractable diagonal brace 203 is provided on the connecting rod 3 on the rear side of the node reinforcement assembly 2;

[0054] The interference support assembly 5 includes a movable groove 500 arranged on the connecting rod 3, a rotating rod 501 is arranged through the movable groove 500, and the upper part of the rotating rod 501 is rotatably arranged in the movable groove 500 through an axis, and the bottom end of the rotating rod 501 is provided with a limiting hook 502 that can interfere with the end of the diagonal support rod 2033. A rotating pressure rod 503 is also provided on the top of the connecting rod 3, one end of the rotating pressure rod 503 is hinged to the top of the connecting rod 3, and the other end is provided with a pressure wheel 505 that can contact the rotating rod 501, and a threaded rod 506 is also provided on the top of the connecting rod 3. The rotating pressure rod 503 is provided with a strip groove 504 for the threaded rod 506 to pass through, and the threaded rod 506 is threadedly sleeved with a locking nut 507 located above the rotating pressure rod 503.

[0055] With this design, the pressure wheel 505 at the end of the rotating pressure rod 503 can be used to press the upper part of the rotating rod 501 by rotating the rotating pressure rod 503, so that the rotating rod 501 rotates, and then the limiting hook 502 at the bottom thereof conflicts with the end of the diagonal support rod 2033. Then, the posture of the rotating pressure rod 503 can be locked by rotating the locking nut 507, so that an effective overall support system can be formed, further strengthening its supporting force. For the specific connection relationship, please refer to Figure 2 shown.

[0056] To avoid affecting the retractable structure during concrete pouring, flexible bags 9 are provided between the first accommodation cavity 1021 and the cross strut 1023, and between the second accommodation cavity 2031 and the diagonal strut 2033. The flexible bags 9 enclose the first communication groove 1022 and the first top strut 1026, or the second accommodation cavity 2031 and the second top strut 2037, for protecting the retractable structure.

[0057] In addition, when the cross strut 1023 or the diagonal strut 2033 is in the retracted state, the flexible bag 9 can be located in the first accommodation cavity 1021 or the second accommodation cavity 2031.

[0058] In this embodiment, the flexible bag 9 is made of a soft rubber material with a smooth surface.

[0059] Secondly, it should be noted that when the device is lifted, it is not necessary to completely retract the cross strut 1023 and the diagonal strut 2033 into the first accommodation cavity 1021 and the second accommodation cavity 2031. During the lifting process, it can be appropriately rotated and avoided by contacting the upper steel mesh, and then it can be easily used again after cleaning. [[ID=1l]]
