Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and particularly relates to a method for fixing a steel wire mesh sheet on the outer side of a composite thermal insulation non-disassembly formwork. Background Art

[0002] With the development of green environmental protection, energy conservation and new technology applications, the construction industry pays more and more attention to the construction period while ensuring the construction quality, and the construction of thermal insulation non-removal formwork meets this demand. During construction, after the construction of composite thermal insulation non-removal formwork and cast-in-place concrete structure is completed, plastering work needs to be carried out on the outside of the composite thermal insulation non-removal formwork. The plastering layer has the function of protecting the base layer and increasing the beauty.

[0003] According to regulations, when the thickness of the plaster layer exceeds 35mm, reinforcement measures such as wire mesh should be taken for plastering construction. By adding wire mesh, cracking and falling of the plaster layer can be effectively prevented. The current method of fixing the wire mesh is to first punch holes from the outer side of the composite non-disassembly insulation formwork into the cast-in-place concrete structure to ensure the anchoring depth, and then fix the wire mesh to the outer side of the non-disassembly insulation formwork by lengthening the expansion screws. This method of fixing the wire mesh has a long length of lengthened expansion screws, which is inconvenient to operate, and its anchoring strength is limited, resulting in unreliable fixation of the wire mesh and extended construction period.

[0027] Example

[0028] Reference Figure 1-4 A method for fixing the outer steel wire mesh of a composite thermal insulation non-disassembly template comprises the following steps:

[0029] S1: Tie-up of steel cage 1;

[0030] S2: A composite thermal insulation non-removable formwork 2 is installed outside the steel cage 1;

[0031] S3: a hole is opened on the composite thermal insulation non-disassembly formwork 2, and an anchor tube 3 is inserted from the composite thermal insulation non-disassembly formwork 2 into the steel cage 1, wherein the inner wall of the anchor tube 3 is provided with a thread;

[0032] S4: the other side of the steel cage 1 is supported by formwork, concrete is cast in the steel cage 1 to form a concrete member 4, and the anchor cylinder 3 is anchored in the concrete member 4;

[0033] After the construction of the concrete component 4 is completed, the concrete component 4 is connected to the composite thermal insulation non-removal formwork 2 as a whole. The composite thermal insulation non-removal formwork 2 does not need to be removed, which can reduce the demolding process and the amount of formwork used, reduce construction costs, and after using the composite thermal insulation non-removal formwork 2, there is no need to install an additional insulation layer during the subsequent construction process, which simplifies the construction steps and improves construction efficiency.

[0034] S5: Lay a steel mesh 5 on the outside of the composite thermal insulation non-disassembly formwork 2, and the fixing bolts 8 pass through the steel mesh 5 and are threadedly connected to the inner wall of the anchor tube 3. After tightening the fixing bolts 8, the heads of the fixing bolts 8 fix the steel mesh 5.

[0035] The anchor tube 3 and the fixing bolt 8 are a complete set of products, which are custom-made by the factory. According to the area of ​​the wire mesh 5, a reasonable number of anchor tubes 3 and fixing bolts 8 are selected, and a corresponding number of holes are opened on the composite thermal insulation non-removal formwork 2. After the wire mesh 5 is fixed, plastering can be performed on the outside of the composite thermal insulation non-removal formwork 2 to form a plastering layer 6.

[0036] The present invention integrally casts the anchor tube 3 into the concrete member 4, which can ensure the anchoring strength of the anchor tube 3, and then fixes the wire mesh by threading the fixing bolts 8 with the inner wall of the anchor tube 3. The threaded connection method is more convenient to operate than the expansion bolts, has a higher connection strength, and can ensure that the wire mesh is firmly fixed.

[0037] In a specific embodiment, the outer wall of the anchor tube 3 is provided with a plurality of anchor rods 31, and the anchor rods 31 at the lower part of the anchor tube 3 are integrally cast in the concrete member 4, which increases the anchoring strength of the anchor tube 3, and the anchor rods 31 at the upper part of the anchor tube 3 can produce a certain degree of extrusion with the inner wall of the hole when the anchor tube 3 is inserted into the composite thermal insulation non-disassembly formwork 2, which has a certain fixing effect on the anchor tube 3. Preferably, the anchor rods 31 are inclined toward the tube mouth direction of the anchor tube 3.

[0038] In a specific implementation scheme, a limiting plate 32 is provided on the outer wall of the tube mouth of the anchor tube 3. After the anchor tube 3 is inserted into the composite thermal insulation non-removal formwork 2, the limiting plate 32 is in close contact with the composite thermal insulation non-removal formwork 2, which can effectively limit the anchor tube 3 and determine the insertion depth of the anchor tube 3.

[0039] In a specific implementation scheme, an anchor cap 7 can be inserted into the mouth of the anchor tube 3 before use. When fixing the wire mesh 5, the anchor cap 7 is removed and the fixing bolt 8 is screwed in. The anchor cap 7 can prevent mud and other debris from entering the anchor tube 3 and affecting the screwing in of the fixing bolt 8.
