Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0031] like figure 1 and 2 As shown in the figure, a template for improving the look and feel quality of the firewall of the main transformer of the substation is used for the segmented construction of the firewall, that is, the segmented firewall is poured through the template. The formwork includes two transverse formwork arranged oppositely, and a longitudinal formwork 7 is fixed between the opposite ends of the two transverse formwork.

[0032] The horizontal template is formed by splicing several sub-templates 6, and the number of the sub-templates 6 is determined according to the actual situation. image 3 The mortise and tenon structure 8 is spliced, and the mortise and ten...

Abstract

The invention discloses a formwork for improving the appearance quality of a firewall of a main transformer of a transformer substation and a construction method. According to the formwork, the pipe head of the pull bolt pipe is subjected to conical treatment, slurry leakage can be effectively prevented, the adjacent sub-formworks are spliced through mortise and tenon structures, the seam gap is reduced, the post-treatment difficulty is reduced, and meanwhile slurry leakage can be prevented. Sectional construction is adopted, flow construction is formed, the formwork turnover rate is increased, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a template and a construction method for improving the look-and-feel quality of a main transformer firewall of a substation, and belongs to the field of construction of a firewall of a main transformer substation. Background technique [0002] The construction of cast-in-place concrete firewall is a key project in the construction of substation engineering. Generally, there are two construction techniques for the construction of cast-in-place concrete firewalls: one-time casting and forming and composite steel formwork construction. One-time forming construction requires a lot of material input and formwork installation is difficult. At present, composite steel formwork is usually used. However, in the construction of combined steel formwork, there are defects such as slurry leakage contamination of the lower wall surface during the concrete pouring of the upper section of the slab wall, and the joint gap is large and difficult ...
