Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a pre-embedded rebar planting mold. Background Technique

[0002] In recent years, for the tie bars between the infill wall and the load-bearing wall, column, beam and slab, post-embedded rebars are often used in construction. Although this construction method is convenient, it often fails to firmly anchor the rebars due to quality problems of the anchoring glue or grouting material, and non-standard operations in drilling, hole cleaning, glue injection or grouting. Usually, after the main body is completed, the operators need to position and drill holes on the end face of the shear wall and the bottom surface of the beam and slab according to the drawing positions. Often, the rebars in the beam or wall are hit during drilling, resulting in the invalidation of this hole. The operators will continue to drill holes beside it until the depth required by the specification can be drilled, generally 100mm - 120mm. Due to avoiding rebars, secondary drilling is caused, and the situation of deviation accounts for about 30% of the total number of drilled holes; secondly, because the electric hammer needs to be carried manually for drilling, more than 40% of the rebar planting holes are not vertical, resulting in a messy state after rebar planting; after that, after drilling, a hair dryer and a brush are needed to clean the holes. The dust left by drilling will seriously affect the pull-out strength after rebar planting; finally, when planting rebars, it is also necessary to strictly mix according to the ratio of the rebar planting glue, wrap the rebar with the glue and then insert it until it overflows and wait for curing. Thus, the rebar planting work is completed. In this process, a series of problems will be involved, such as damaging the main structure rebars, the appearance of concrete, the deviation of the tie bar rebars in the construction column causing difficulty in closing the formwork, the pull-out strength of the rebar planting not meeting the requirements, dust pollution during drilling, noise pollution, occupational diseases, etc. Content of the Utility Model

[0003] The utility model aims to solve the above problems, and thus provides a pre-embedded rebar planting mold that can firmly anchor the rebars.

[0004] The technical solution adopted by the utility model to solve the above problems is as follows:

The inner side of the open end of the positioning shell is provided with internal threads. The outer side of the formwork is provided with a plug screwed to the open end of the positioning shell. A glue blocking component is arranged on the inner side of the positioning shell adjacent to the inner end of the internal threads, and a stirring hole is opened at the center position of the glue blocking component.

[0006] The utility model adopting the above technical solution, compared with the prior art, has the following prominent features:

[0024] The following further describes the present utility model in conjunction with embodiments, and the purpose is only to better understand the content of the present utility model. Therefore, the examples given do not limit the protection scope of the present utility model.

[0025] An embedded rebar planting mold includes a positioning housing embedded in a formwork. The positioning housing is tubular and blocked at one end. A rebar planting glue bag is arranged inside the positioning housing. The rebar planting glue bag is bag-shaped and filled with rebar planting glue inside. A base 4 that fits against the inner side of the formwork is arranged at the open end of the positioning housing. The base 4 ensures the perpendicularity of the positioning housing and the formwork. An internal thread is provided on the inner side of the open end of the positioning housing. A plug 5 that is screwed to the open end of the positioning housing is arranged on the outer side of the formwork. A hole is opened in the formwork according to the rebar planting position on the drawing. The plug 5 passes through the hole and is screwed to the open end of the positioning housing. One side of the plug 5 is an external thread structure for screwing with the internal thread, and the other side of the plug 5 is a handle. A clamping plate that is stuck on the outer side of the formwork is arranged in the middle of the plug 5. The plug 5 fixes the positioning housing. A glue blocking assembly is arranged on the inner side of the positioning housing and adjacent to the inner end of the internal thread. A stirring hole is opened at the center position of the glue blocking assembly. A hand drill enters the positioning housing through the stirring hole to stir and break the outer skin of the rebar planting glue bag. The glue blocking assembly ensures that the rebar planting glue bag does not leak out for a short time after being punctured.

[0026] Further, the positioning housing includes opposite left housing 1 and right housing 2. The left housing 1 and the right housing 2 are made of nylon material. A positioning groove and a positioning strip for cooperating use are arranged on the contact surface between the left housing 1 and the right housing 2. A positioning groove is arranged on the left housing 1, and a positioning strip is arranged on the right housing 2. Card slots are arranged at intervals on both sides of the housing of the right housing 2. Buckles 3 that cooperate with the card slots are arranged on both sides of the housing of the left housing 1.

[0027] Further, both sides of the rebar planting glue bag are clamped between the contact surfaces of the left housing 1 and the right housing 2, fixing the position of the rebar planting glue bag for easy puncturing and also preventing leakage of slurry between the left housing 1 and the right housing 2 when pouring concrete.

[0028] Further, the glue blocking assembly includes semi-circular elastic thin partitions 6 respectively arranged on the inner sides of the left housing 1 and the right housing 2 and close to the internal thread. The elastic thin partitions 6 are made of nylon. After the left housing 1 and the right housing 2 are butted, the two semi-circular elastic thin partitions 6 form a ring, and there is a stirring hole in the middle of the ring. The semi-circular elastic thin partition 6 is composed of several fan-shaped partition units. The elastic thin partition 6 ensures that the planting glue bag will not leak out in a short time after being punctured. The diameter of the steel bar is larger than the diameter of the stirring hole, and then the steel bar directly abuts against the ring-shaped elastic thin partition 6 and is inserted into the positioning housing.

[0029] Further, a plurality of layers of outer anti-slip ribs 7 are arranged on the outer periphery of the positioning housing along the circumferential direction, increasing the bonding performance with the concrete.

[0030] Further, a reinforcing rib 8 is arranged between adjacent outer anti-slip ribs 7 on the outer side of the positioning housing to prevent the positioning housing from deforming.

[0031] Further, a plurality of layers of inner anti-slip ribs 9 are arranged on the inner periphery of the positioning housing along the circumferential direction. The inner anti-slip ribs 9 and the outer anti-slip ribs 7 are located at the same horizontal position to increase the gripping force. The inner diameter of the inner anti-slip ribs 9 is adapted to the steel bar, increasing the stability of the steel bar in the positioning housing.

[0032] Further, a plurality of anti-tilting ribs 10 are arranged outside the open end of the positioning housing. One side of the anti-tilting ribs 10 is attached to the inner side surface of the formwork, and the anti-tilting ribs 10 further ensure the perpendicularity of the positioning housing and the formwork.

[0033] First, determine the drilling position, then fix the positioning housing on the formwork through the plug 5 for pre-embedding to prevent deviation, and ensure the perpendicularity of the planting hole by fitting the base 4 on the inner side surface of the formwork. After the concrete is formed, use a hand drill to stir and damage the planting glue bag through the stirring hole, insert the steel bar into the positioning housing, ensure that the steel bar is fully wrapped by the glue, complete the steel bar planting, avoid damaging the concrete, and secondly solve a series of problems such as traditional drilling dust pollution, noise pollution, and occupational diseases.
