Embodiment 1

[0035] see figure 1 , a wall connecting piece, including a limiting steel pipe 1 and a positioning steel pipe 2 fixed on the limiting steel pipe 1 . The wall connecting piece is fixed on the wall body 3 provided with positioning holes, the positioning steel pipe 2 is pierced in the positioning hole, the limiting steel pipe 1 is connected with the positioning steel pipe 2 and clamped on both sides of the wall body 3 to complete the wall connecting piece of the lock.

[0036]The limit steel pipe 1 includes a first limit tube 11 positioned inside the wall body 3 and a second limit tube 12 positioned outside the wall body 3. The lengths of the first limit tube 11 and the second limit tube 12 are consistent and mutually Parallel and arranged at the same height relative to the wall body 3 . Both the first limiting tube 11 and the second limiting tube 12 are arranged along the length direction of the wall body 3 . Between both ends of the first limiting tube 11 and the inner side ...

Embodiment 2a

[0044] In embodiment 1, self-made waterborne acrylic acid modified epoxy ester primer is made by following preparation method:

[0045] Step1, add 3kg water-based epoxy ester resin to the batching tank, add 0.3kg polyaniline, 0.15kg dispersant, 1.5kg deionized water, 0.02kg defoamer, 0.5kg anti-rust pigment, 0.01kg clay, 0.01 kg silane coupling agent KH570, 0.01kg graphene oxide, grind evenly by a three-roller machine, remove the filter residue through a 500-mesh sieve, and obtain a pigment slurry;

[0046] Step2, add the pigment slurry prepared in Step1, 0.01kg leveling agent and 0.2kg film-forming aid to 3.5kg of acrylic emulsion while stirring, and add 0.02kg of thickener to adjust the viscosity to obtain the water-based acrylic modified ring Oxygen ester primer.

[0047] in:

[0048] The dispersant was purchased from CNOOC Changzhou Environmental Protection Coatings Co., Ltd., the model is BYK-190;

[0049] The defoamer was purchased from CNOOC Changzhou Environmental P...

Embodiment 3a

[0066] The difference between embodiment 3a and embodiment 2a is that embodiment 3a also adds the pH neutralizer of 0.005kg and the anti-settling agent of 0.01kg in Step2, and the anti-settling agent is organic bentonite and fumed silica according to the mass ratio of 1:1 composite. The pH neutralizer is ammonia water.

[0067] The preparation method of embodiment 3b-embodiment 3e is the same as that of embodiment 3a, and the only difference is that the specific components and parameters of the pH neutralizer and the specific component parameters of the anti-settling agent are different. The specific results are shown in the table below (unit: kg):

[0068]

[0069] The primer prepared in Example 2a-Example 2e is sprayed on the wall connecting piece disclosed in Example 1, and the wall connecting piece is degreased and phosphated before spraying; the sprayed wall connecting piece is baked at 80°C until solidified After the temperature reaches 30%, spray UV-curable acrylic...

Abstract

The invention discloses a high-safety steel wall-connecting piece. The high-safety steel wall-connecting piece solves the problem that connection points between the wall-connecting piece and a wall body are mainly concentrated on the outer side of the wall body, and the connection points bear a large stress and is easy to cause potential safety hazards once cracks occur in the wall body connectionpoints. According to the key point of the technical scheme, the high-safety steel wall-connecting piece comprises a limiting steel pipe and a positioning steel pipe fixedly arranged on the limiting steel pipe, wherein the limiting steel pipe comprises a first limiting pipe arranged on the inner side of the wall body and a second limiting pipe arranged on the outer side of the wall body, the positioning steel pipe is correspondingly and vertically connected with the first limiting pipe and the second limiting pipe through fasteners, the stress points between of the wall body and the wall-connecting piece is dispersed, and the safety of the wall-connecting piece is improved.

Description

technical field [0001] The invention relates to scaffold construction, in particular to a high-safety steel wall connecting piece. Background technique [0002] Scaffolding has always been used in construction engineering, and in construction engineering, the scaffolding body is connected to the main structure of the building through a wall-connecting structure. The wall connection structure generally refers to a component that strengthens the stability of other structures by connecting with a reliable fixed end, and can transmit tension and pressure. The wall-attached connection realized by the wall-connecting structure plays a very important role in strengthening the overall stability of the scaffold, improving its stable bearing capacity and avoiding major accidents such as toppling or collapse. [0003] For example, the utility model whose authorized announcement number is CN203594218U belongs to the technical field of design and manufacture of equipment or facilities c...
