A kind of safety shelter for building construction site

Abstract

A protective shelter for a stirring machine; provided is a protective shelter for a stirring machine, comprising a basic structure and a force-unloading structure (1); the basic structure comprises a steel structure support frame and a fixed protective layer (2), forming a support frame and the most basic overhead protection measure; the force-unloading structure (1) comprises a moving plate 1 (3), a moving plate 2 (4), and springs (5) connecting the moving plate 1 (3), the moving plate 2 (4), and the fixed protective layer (2), forming an energy absorption structure; the force-unloading structure (1) also comprises a sliding mesh (8) arranged on the upper surface of the moving plate 1 (3) and the moving plate 2 (4); the sliding of the sliding mesh (8) along the moving plate 1 (3) and the moving plate 2 (4) increases the strokes of falling objects during collision, reducing the interaction force during collision, such that the falling object cannot easily penetrate through the protection. The present protective shelter has a simple structure and rational design; when an object falls from a height, the force-unloading structure (1) can relieve the impact force of the falling object, preventing the impact force of the falling object breaking through the top protection.

Description

[0001] This case is a divisional application. The invention title of the original application is: a mixer shelter. The original application date is 2017-05-02, and the original application number is 201710298996.2. Technical field [0002] The invention relates to an engineering safety management facility, in particular to a protective shed for a mixer. Background technique [0003] Construction site operation is a high-risk production activity, and the mixers produced on the construction site need to be produced under the protective shed. There are many sources of danger in the construction site. Falling objects are one of the major sources of on-site construction. It is also a production safety accident that can easily occur at the construction site. This source of danger is always present and often hurts on-site construction and management personnel. It is fatal, and serious economic losses can also cause project losses. At present, the installation of fastener-type steel pipe...

Problems solved by technology

There are many danger sources in the building construction site. The falling of objects is one of the major danger sources in the construction site, and it is also a production safety accident that is very likely to occur in the construction site. It is fatal, and if it is serious, it will also cause economic losses to the project

At present, the construction of fastener-type steel pipe protective sheds on site is a common way for mixer protective sheds at present. However, since it is only a temporary facility, the gravity bearing capacity of the entire protective shed is relatively limited. A few have additional layers of stencils added for strength

Obviously, for objects falling from high altitude, such as bricks, steel structure parts, etc., such overhead protection is obviously easy to be penetrated
