Embodiment Construction
[0045] In order to make the purpose and technical solution of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.
[0046] like Figure 1-5 Shown, a kind of construction method of frame support clear-faced concrete protective cap comprises the steps:
[0047] Step 1, making a mold: the mold includes a cylinder body 1 and an arc structure part 2, the arc structure part 2 is fixedly arranged on the upper end of the inner wall of the cylinder body 1, and the arc structure part 2 is arranged close to the inner wall of the cylinder body 1; The inner side of the cross-section of the mold is a circle or a regular polygon with four or more sides; the arc structure 2 is a ring structure, and its inner surface is an upwardly concave arc surface 21, which is used to outline the upper part of the protective cap. Rounded corners 41; by setting the arc str...

Abstract
The invention discloses a construction method of a structural support bare concrete protective cap. The construction method includes the following steps that 1, a mold is manufactured, wherein the mold comprises a barrel and an arc structure part; 2, a cushion layer is laid; 3, the mold is installed, wherein a structural support pipe is sleeved with the mold; 4, concrete is poured, wherein pouring of a protective cap body and maintaining are carried out; 5, the mold is detached, and maintenance is carried out, wherein after the protective cap meets strength requirements, the mold is detached, the protective cap continues to be subjected to coverage and heat preservation and moisture preservation maintenance for 4 d to 5 d. Through the arrangement of the arc structure part, the concrete pouring process of the protective cap is improved, arc chamfers are formed at a time without secondary repairing, efficiency is high, and forming is good. The barrel and the arc structure part are arranged in a split mode, and replacement and maintenance are convenient. The barrel of the mold is made of glass fiber reinforced plastic, the circulation frequency of the mold is increased, energy is saved, and environment friendliness is achieved. By the adoption of the step-by-step pouring and repeated vibrating process, it is guaranteed that the compactness of the protective cap is good, the surface forming quality is good, and no pitted surface exists.
Description
Technical field: [0001] The invention belongs to the technical field of fair-faced concrete construction, and in particular relates to a construction method of a fair-faced concrete protective cap of a structure bracket with arc chamfering. Background technique [0002] In the prior art, the current main steps of the protective cap of the steel pipe structure support in the substation project are: making a wooden mold or a steel mold for the protective cap, installing the mold, pouring concrete, removing the mold, chamfering the arc, secondary repairing of the concrete surface, and concrete curing. [0003] There are following main deficiencies: [0004] 1. Using wooden moulds, the seams are of poor quality, easy to leak, and the number of turnovers is small. [0005] 2. The steel mold is used. Usually, the mold is spliced by two pieces, and the bending part of the mold is arc-shaped. It is easy to leak grout, and there will be an extra piece of concrete, which needs to b...
