Description

Technical Field

[0001] This utility model belongs to the field of fixing device technology, specifically relating to a fixing structure and a steel mesh. Background Technology

[0002] Brick-concrete structures were once widely used in my country due to their ease of construction and low cost. However, they also suffer from poor seismic performance, limited spatial layout, restricted building height, and insufficient material durability. Therefore, over time, the walls of brick-concrete structures often require reinforcement. A common method is the double-sided steel mesh and cement mortar surface reinforcement process. This involves installing double-sided steel mesh on the original structural surface and then applying a high-strength cement mortar layer to achieve structural reinforcement. When installing the steel mesh, tie rods need to be installed in the wall to fix the reinforcing bars. The conventional method is to fix the tie rods to the wall and then bend them. This method has two drawbacks: firstly, the bending angle of the tie rods may not meet design requirements; secondly, bending the tie rods manually after installation is inconvenient, leading to low efficiency. Therefore, how to fix the reinforcing bars in the wall is a technical problem that needs to be solved. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

Therefore, they should not be construed as limitations on this utility model.

[0022] On one hand, this application provides a fixing structure for installation on a wall 12, the wall 12 having a first through hole 13. The fixing structure includes a sleeve 1 and two tie rods 4. The sleeve 1 is inserted into the first through hole 13, and the interior of the sleeve 1 is filled with adhesive material. The two tie rods 4 include a rod portion 2 and a bent portion 3. The rod portion 2 is inserted into the sleeve 1, and the bent portions 3 of the two tie rods 4 are respectively located on both sides of the sleeve 1.

[0023] The sleeve 1 is used to contain the adhesive material. Under the action of the adhesive material, the tie rod 4 and the sleeve 1 can be bonded together, and the two tie rods 4 can also be bonded together, so that the sleeve 1 and the tie rod 4 can form an integral structure.

[0024] The bent portion 3 of the tie bar 4 is used to hook onto the reinforcing bar. For example, when the fixing structure of the embodiment of this application is applied to the cement mortar surface reinforcement process of the double-sided steel mesh 11, the first through hole 13 of the wall 12 can be set at the intersection of two reinforcing bars of the steel mesh 11, and the tie bar 4 is hooked at the intersection of the two reinforcing bars.

[0025] The bent portions 3 of the two tie rods 4 are respectively set on both sides of the sleeve 1, so that the steel mesh 11 on both sides of the wall 12 can be fixed by the tie rods 4.

[0026] In this embodiment, the tie rod 4 and the sleeve 1 can be bonded together using the adhesive material, and two tie rods 4 can also be bonded together, allowing the sleeve 1 and the tie rod 4 to form an integral structure, ensuring the connection strength of the two tie rods 4. Simultaneously, the tie rod 4 can be pre-formed using mechanical bending, which, compared to bending on the wall, ensures that the bending angle meets design requirements and improves the fixing effect on the reinforcing steel. Furthermore, after inserting the tie rod 4 into the sleeve 1, it can be fixed using the adhesive material, making fixing convenient and quick.

[0027] In some embodiments, the adhesive material includes rebar adhesive.

[0028] Rebar adhesive has many advantages, such as high bonding strength, room temperature curing, low shrinkage during hardening, good temperature resistance, and excellent toughness and impact resistance after curing. Using rebar adhesive can improve the fixing reliability of the tie rod 4.

[0029] In some embodiments, the material of the tie rod 4 includes steel bars, and the surface of the steel bars is provided with transverse ribs.

[0030] The tie rod 4 is made of steel bars, which improves the structural strength of the tie rod 4 and ensures the reliability of the tie rod 4 in fixing the steel mesh 11.

[0031] The transverse ribs on the surface of the reinforcing bar can improve the reliability of the connection between the tie bar 4 and the bonding material, thereby improving the connection strength of the two tie bars 4.

[0032] In some embodiments, the sleeve 1 is further provided with two partial sealing parts 10, which are respectively disposed inside both ends of the sleeve 1. The top of the partial sealing part 10 is provided with a second through hole 8, and the bottom of the partial sealing part 10 is provided with a third through hole 9. The cross-sectional area of ​​the second through hole 8 is larger than the cross-sectional area of ​​the third through hole 9.

[0033] The partial sealing part 10 is used to partially block the end of the sleeve 1, which hinders the flow of adhesive material out of the sleeve 1, increases the filling effect of adhesive material on the internal space of the sleeve 1, and thus improves the fixing effect of adhesive material on the tie rod 4.

[0034] The top of the partial sealing part 10 refers to the part above the sleeve 1 after it is installed in the first through hole 13, while the bottom of the partial sealing part 10 is the part below.

[0035] The second through hole 8 can be used to allow the rod part 2 of the tie rod 4 to pass into the sleeve 1. At the same time, since the second through hole 8 is larger than the third through hole 9, it can be used to inject adhesive material into the sleeve 1.

[0036] The third through hole 9 can be used for the rod part 2 of the tie rod 4 to pass through. When the rod parts 2 of the two tie rods 4 are inserted into the sleeve 1, the rod parts 2 of the two tie rods 4 can be set up vertically. That is, the rod part 2 of one tie rod 4 can be inserted into the sleeve 1 through the second through hole 8, and the rod part 2 of the other tie rod 4 can be inserted into the sleeve 1 through the third through hole 9.

[0037] In embodiments where the tie bar 4 is made of reinforcing steel, the second through hole 8 and the third through hole 9 can prevent the tie bar 4 from detaching, reducing the risk of the tie bar 4 coming out of the sleeve 1 during the curing process of the adhesive material. Specifically, since the surface of the reinforcing steel is provided with transverse ribs, when the tie bar 4 tends to come out of the second through hole 8 or the third through hole 9, the transverse ribs can abut against the port of the second through hole 8 or the third through hole 9, reducing the risk of the tie bar 4 coming out of the sleeve 1.

[0038] Since the two partial sealing parts 10 are arranged opposite each other, that is, their third through holes 9 are arranged opposite each other, the rod part 2 of the tie rod 4 inserted into the third through hole 9 can pass through the third through hole 9 of both partial sealing parts 10 at the same time. The advantage of this arrangement is that, on the one hand, the shape and structure of the two partial sealing parts 10 can be set to be the same, so it is not necessary to block the third through hole 9 of one of the partial sealing parts 10 in order to increase the sealing effect on the adhesive material, thereby reducing manufacturing costs. On the other hand, in embodiments where the material of the tie rod 4 includes steel bars, the rod part 2 of the tie rod 4 passing through the two third through holes 9 can further increase the anti-detachment effect of the tie rod 4.

[0039] In the actual construction process, the partial sealing part 10 can be installed on the sleeve 1 first, then the sleeve 1 can be inserted into the first through hole 13 of the wall 12, and adhesive material can be injected into the sleeve 1 through the second through hole 8. Finally, the rod part 2 of the tie rod 4 can be inserted into the second through hole 8 or the third through hole 9.

[0040] In some embodiments, the partial sealing portion 10 includes a panel 5 and an arc segment 6. The panel 5 is semi-circular, and a third through hole 9 is disposed on the panel 5. The two ends of the arc segment 6 are connected to the panel 5, and the arc segment 6 and the panel 5 form a disk structure, with a second through hole 8 formed inside the arc segment 6.

[0041] The arc segment 6 and the panel 5 form a disc structure, which on the one hand allows the shape of the partial sealing part 10 to be adapted to the shape of the inner wall of the sleeve 1. On the other hand, the edge of the disc structure is a complete circle, which allows the partial sealing part 10 to be connected to the sleeve 1 by means of interference fit or threaded connection.

[0042] The arc segment 6 and the edge of the panel 5 form a second through hole 8. This allows the second through hole 8 to be set as large as possible, facilitating the insertion of the tie rod 4 into the second through hole 8 and the injection of adhesive material into the sleeve 1. Users can also use the second through hole 8 as an operating hole, adjusting the position of the partially obstructed part in the sleeve 1 by hooking their fingers through the second through hole 8 onto the panel 5. Furthermore, the panel 5 is only used to house the third through hole 9, allowing for the reasonable design of the size and position of the third through hole 9 as needed.

[0043] In some embodiments, the inner wall of the sleeve 1 is provided with threads, and the partial sealing part 10 is threadedly connected to the sleeve 1.

[0044] In an embodiment where the partial sealing part 10 includes an arc segment 6 and a panel 5, the outer peripheral wall of the disc structure formed by the arc segment 6 and the panel 5 is correspondingly provided with threads, so that the partial sealing part 10 and the sleeve 1 can be threadedly connected.

[0045] The local sealing part 10 is threaded to the sleeve 1, which not only improves the connection strength between the local sealing part 10 and the sleeve 1, but also allows the position of the local sealing part 10 inside the sleeve 1 to be adjusted.

[0046] In some embodiments, the two opposite end faces of the two partial sealing portions 10 are respectively provided with arc protrusions 7, the concave side of the arc protrusions 7 faces the axis of the sleeve 1, and the outer wall of the arc protrusions 7 abuts against the inner wall of the sleeve 1.

[0047] In an embodiment where the partial sealing portion 10 includes a panel 5 and an arc segment 6, the arc protrusion 7 may be disposed on the panel 5.

[0048] To reduce costs, the local sealing part 10 can be designed as a thin-walled structure. However, the thin-walled structure has a small contact area with the inner wall of the sleeve 1, making it prone to misalignment or deformation damage. By providing an arc-shaped protrusion 7 in the local sealing part 10, the structural strength of the local sealing part 10 is increased.

[0049] In some embodiments, the arcuate protrusion 7 is disposed at the bottom of the partial sealing portion 10.

[0050] This design increases the support effect of the arc protrusion 7 on the local sealing part 10.

[0051] The arc protrusion 7 can be set along the edge of the panel 5, that is, if the panel 5 is semi-circular, then the arc protrusion 7 can also be semi-circular.

[0052] In some embodiments, the sleeve 1 is made of PVC.

[0053] The PVC sleeve 1 has good corrosion resistance, high tensile and compressive strength, good hardness, and wear resistance. This ensures that the performance of sleeve 1 meets the requirements.

[0054] On the other hand, this application provides a steel mesh 11, which includes the fixing structure in the above embodiments.

[0055] The reinforcing mesh 11 is the reinforcing mesh 11 required in the double-sided reinforcing mesh 11 cement mortar surface reinforcement process. The specific steps and required materials of the double-sided reinforcing mesh 11 cement mortar surface reinforcement process are well known to those skilled in the art and will not be described here.

[0056] When using the double-sided steel mesh 11 cement mortar surface reinforcement process, the fixing structure of this application embodiment can be constructed according to the following steps:

[0057] 1. Make the tendons 4.

[0058] 2. After the reinforcement mesh 11 is installed according to the design requirements, drill holes at the intersections of the reinforcement mesh 11 according to the hole spacing required by the design drawings. Generally, the holes are arranged in a quincunx or rectangular pattern to ensure accurate hole positions.

[0059] 3. Use an electric drill to drill a hole in wall 12, making sure the hole completely penetrates wall 12.

[0060] 4. Use an air pump or brush to clean the dust inside the hole to ensure it is clean.

[0061] 5. Insert sleeve 1 into the drill hole, with both ends of sleeve 1 flush with the wall 12.

[0062] 6. Start injecting adhesive from one side of sleeve 1, slowly push it in, and ensure that the inside of sleeve 1 is full of adhesive. Ensure that the adhesive is fully filled until the anchoring adhesive flows out naturally.

[0063] 7. Slowly rotate the prefabricated tie bar 4 into the sleeve 1, adjust the position of the tie bar 4, and ensure that the hook holds the node of the steel mesh 11.

[0064] 8. Curing adhesive.
