Technical Field
[0001] The utility model relates to the technical field of infilled walls, in particular to a forming structure for threaded blind holes of precast infilled walls. Background Art
[0002] The existing forming structure for threaded blind holes has poor effects, and metal bellows are generally used. This material is a consumable and cannot be reused for turnover. For this reason, we propose a forming structure for threaded blind holes of precast infilled walls. Content of the Utility Model
[0003] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a forming structure for threaded blind holes of precast infilled walls.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] A forming structure for threaded blind holes of precast infilled walls, including a forming hole shaft, and the forming hole shaft is in a conical shape;
[0006] A bolt hole is arranged in the middle of the forming hole shaft;
[0007] A grouting hole tooling shaft is fixedly installed on one side of the bottom of the forming hole shaft;
[0008] An out-grouting hole tooling shaft is fixedly installed on the other side of the bottom of the forming hole shaft and is symmetrical with the grouting hole tooling shaft.
[0009] As a preferred technical scheme of the utility model, holes one and two are respectively installed on both sides of the bottom end of the forming hole shaft, hole one is correspondingly connected with the grouting hole tooling shaft, and hole two is correspondingly connected with the out-grouting hole tooling shaft.
[0010] As a preferred technical scheme of the utility model, a reserved hole is left after the grouting hole tooling shaft is embedded into hole one.
[0011] As a preferred technical scheme of the utility model, a reserved hole is left after the out-grouting hole tooling shaft is embedded into hole two.
[0012] As a preferred technical scheme of the utility model, support seats are fixedly installed at the bottom ends of the grouting hole tooling shaft and the out-grouting hole tooling shaft, and the bottoms of the two support seats are aligned with each other.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] Good forming effect of the threaded blind hole: The forming effect of the threaded blind hole of the precast infilled wall component produced by using this tooling is good, and the visual quality of the component is guaranteed;
[0015] High turnover rate and low comprehensive cost: This tooling is a machined part and can be reused repeatedly. It replaces the metal bellows used in previous production. This material is a consumable and cannot be reused repeatedly. Therefore, by using this tooling, it can be used in various projects, improving the turnover utilization rate of the tooling and reducing the comprehensive cost of factory operation;
[0016] The quality of grouting operation is guaranteed: When using metal bellows for forming and supporting the use of grouting holes and slurry outlet holes for bellows forming, it is easy to be blocked during the production process, or due to problems such as the operation of the embedded workers and the length of the grouting bellows, quality defects such as difficult grouting are likely to occur. However, by using the one-hole forming tooling, problems such as blockage of grouting holes and slurry outlet holes and high grouting pressure can be effectively avoided. Description of the Drawings

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention;
[0023] Refer to Figures 1-3 , a forming structure for threaded blind holes in precast infill walls, including a forming hole shaft 1, and the forming hole shaft 1 is in a conical shape;
[0024] A bolt hole 4 is arranged in the middle of the forming hole shaft 1;
[0025] A grouting hole tooling shaft 2 is fixedly installed on one side of the bottom of the forming hole shaft 1;
[0026] A slurry outlet hole tooling shaft 3 is fixedly installed on the other side of the bottom of the forming hole shaft 1 and is symmetrical with the grouting hole tooling shaft 2.
[0027] On both sides of the bottom end of the formed hole shaft 1, a hole one 6 and a hole two 7 are respectively installed. The hole one 6 is correspondingly connected to the grouting hole tooling shaft 2, and the hole two 7 is correspondingly connected to the slurry outlet hole tooling shaft 3. The hole one 6 is the grouting hole, and the hole two is the slurry outlet hole.
[0028] After the grouting hole tooling shaft 2 is embedded into the hole one 6, a reserved hole is left.
[0029] After the slurry outlet hole tooling shaft 3 is embedded into the hole two 7, a reserved hole is left.
[0030] Support seats 5 are fixedly installed at the bottom ends of both the grouting hole tooling shaft 2 and the slurry outlet hole tooling shaft 3, and the bottoms of the two support seats 5 are aligned with each other.
[0031] The operation process is as follows: Screw the grouting hole tooling shaft 2 and the slurry outlet hole tooling shaft 3 into the hole one 6 and the hole two 7 on the threaded blind hole taper formed hole shaft 1 respectively.
[0032] Check the bottom die positioning hole of the assembled threaded blind hole forming tooling according to the detailed design drawing. After confirmation, use an M16 bolt to screw into the threaded blind hole and fixedly connect it to the bolt hole 2 of the bottom die of the mold;
[0033] Check whether the tooling is firmly connected to the mold, and whether the grouting hole shaft and the slurry outlet hole shaft are fully attached to the mold table;
[0034] After completing the above processes, carry out processes such as steel bar binding, embedding, and pouring. After the concrete strength reaches the form removal strength, use special tools to remove the grouting hole tooling shaft 2 and the slurry outlet hole tooling shaft 3.
[0035] Using this tooling to produce precast infill wall components has a good forming effect of threaded blind holes, and the visual quality of the components is guaranteed;
[0036] High turnover rate and low comprehensive cost: This tooling is a machined part and can be reused repeatedly. It replaces the metal corrugated pipe used in previous production. This material is a consumable and cannot be reused repeatedly. Therefore, using this tooling can be applied to each project, improve the turnover rate of the tooling, and reduce the comprehensive operation cost of the factory;
[0037] The quality of the grouting operation is guaranteed: When using the metal corrugated pipe to form, supporting the use of the grouting hole and the slurry outlet hole formed by the corrugated pipe, it is easy to be blocked during the production process, or due to problems such as the operation of the embedding worker and the length of the grouting corrugated pipe, quality defects such as difficult grouting are likely to occur. However, using the one-hole forming tooling can effectively guarantee and avoid problems such as blockage of the grouting hole and the slurry outlet hole and high grouting pressure.
