Description

Technical Field

[0001] This utility model relates to the field of auxiliary device protection technology for civil defense engineering, specifically a new type of positioning template for wall-penetrating sleeves of civil defense doors. Background Technology

[0002] In building construction, air-raid shelter doors are key protective facilities in air-raid shelter projects. Their installation quality directly affects the reliability of the entire protection system. Wall sleeves, as an important component in the installation process of air-raid shelter doors, are used for the protection and sealing of pipelines when they pass through walls. Their positioning accuracy and installation verticality have a significant impact on the subsequent construction quality and overall structural safety.

[0003] Traditional methods for locating through-wall sleeves often involve manual measurement, marking, and slotting, which suffers from low efficiency, large errors, and difficulty in ensuring verticality. Especially in complex wall structures or civil defense projects with high-strength protection requirements, traditional methods cannot meet the high-precision positioning needs, easily leading to rework and repairs, increasing construction costs and schedule risks. In addition, during the formwork erection process, conventional formwork structures are simple and have poor adjustability, making it impossible to achieve synchronous positioning and unified calibration of the inner and outer sides, further affecting the installation quality of the through-wall sleeves.

[0008] Four first templates and two second templates are provided. The left and right ends of the two second templates are respectively fixed to the upper ends of the four first templates facing each other on one side wall by bolts, forming two sets of door frame templates.

[0009] Two fixing rods are fixedly connected to the lower side of the four first templates at their left and right ends, respectively, to reinforce the entire template.

[0010] Four third templates are fixed symmetrically to the right side walls of the two first templates on the right side.

[0011] Preferably, each of the four first templates, two second templates, and four third templates has a number of holes and slots linearly formed. The two sets of templates are respectively set on the inner and outer sides of the air-raid shelter door opening and are fixed by bolts passing through the holes and slots on the two sets of templates.

[0012] Preferably, it also includes a threshold template, which is fixed at the threshold of the air-raid shelter door, and the threshold template has three slots linearly formed on it.

[0013] Preferably, the width of the door frame template composed of the two first templates and the second template includes 860cm, 1260cm, 1560cm and 2060cm.

[0014] Beneficial effects

[0015] Compared with the prior art, this utility model provides a novel positioning template for wall-penetrating sleeves of air-raid shelter doors, which has the following beneficial effects:

[0016] In this utility model, two sets of door frame templates, consisting of four first templates and two second templates, are respectively set on the inner and outer sides of the air-raid shelter door opening, and their positions are corresponding. The holes and slots opened on the two sets of door frame templates and the threshold template can conveniently and accurately position the slots of the through-wall sleeves, and at the same time improve the verticality of the slots of the through-wall sleeves.

[0030] Two fixing rods 5 are fixedly connected to the lower side of the four first templates 1 at their left and right ends, respectively, to reinforce the entire template;

[0031] Four third templates 3 are fixed symmetrically to the right side walls of the two first templates 1 on the right side, one above the other.

[0032] Specifically, the two sets of door frame templates, consisting of four first templates 1 and two second templates 2, are adapted to the size and style of the air-raid shelter door openings.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, several holes and slots 4 are linearly opened on the four first templates 1, two second templates 2 and four third templates 3. The two sets of templates are set on the inner and outer sides of the air-raid shelter door opening respectively, and are fixed by bolts passing through the holes and slots 4 on the two sets of templates.
