Abstract
The utility model discloses a blast resistant door. The door comprises a door leaf. The door leaf is provided with a blast impact resistant surface and a back surface opposite to the blast impact resistant surface. The blast impact resistant surface is arched. The blast resistant door is based on bearing characteristics of the blast resistant door under a blast load, i.e., the largest stress strain of the blast resistant door is concentrated on the central position of the door leaf, and the part having large stress strain of the blast resistant door is reinforced. The door achieves good blast resistance and penetration resistance, so that material utilization rate is improved, particularly for large-size blast resistant doors, and deformation of central part of the door leaf is reduced.
Description
Technical field
The utility model relates to a kind of blast-resistant door.This blast-resistant door is applicable to the safety protection field in the regions such as industrial construction, military engineering, chemical industry manufacturing industry.
Background technology
When blasting, blast-resistant door can, under the intact prerequisite of assurance self, ensure the intact of the interior personnel of building and equipment.Common blast-resistant door is generally steel blast-resistant door, also has wooden and wooden lining steel plate blast-resistant door.The shape of blast-resistant door mainly be take plain batton door as main, and its structure is comprised of doorframe, door leaf, and there is the pin-and-hole coordinating with door leaf bearing pin on doorframe both sides, wherein also has the lockhole mating with antiknock lock on one side; Door leaf is made by skeleton and the welding of interior outer panels, and bearing pin is all equipped with on door leaf both sides, Yi Bian hinge is wherein housed, another side is equipped with handle antiknock lock.There is following problem in this type of steel plateform blast-resistant door:
(1) when door leaf bears compared with huge explosion impact load, door leaf design thickness needs to increase, and can cause like this cost to improve, and the stock utilization at part-structure place is not very high;
(2), when door leaf size is larger, door leaf middle part deflection is excessive, cannot meet instructions for use.
Summary of the invention
The purpose of this utility model is blast-resistant door, and to solve, the stock utilization that existing blast-resistant door exists is low, the yielding problem in size larger blast-resistant door middle part.
For this reason, the blast-resistant door that the utility model provides comprises door leaf, and this door leaf is provided with explosion-proof shock surface and the back side relative with being provided with explosion-proof shock surface, and described explosion-proof shock surface is arcuate surface.
Other technologies of the present utility model are characterized as:
The axis of described arcuate surface is positioned at the long axis place of door leaf.
Described blast-resistant door also comprises doorframe, and described door leaf is installed in doorframe.
Described door leaf is assembled by skeleton and panel.
Compared with prior art, the utility model has the advantage of:
(1), when the utility model is subject to shock, under the intact prerequisite of assurance self, external impact energy can effectively dissipate.
(2) blast-resistant door of the present utility model is according to the loading characteristic of blast-resistant door under explosive load, be that the strain of blast-resistant door maximum stress concentrates on door leaf center, blast-resistant door ess-strain is strengthened compared with large part, anti-knock properties, penetration-resistant are better, thereby improved the utilization rate of material, especially to larger-size blast-resistant door, reduced the deflection at door leaf middle part.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is further explained to explanation.
Fig. 1 is the structural representation of door leaf of the present utility model;
Fig. 2 is the structural representation of Curved beam of the present utility model.
Specific implementation method
The utility model, according to the ess-strain distribution situation of dull and stereotyped blast-resistant door under explosive load, proposes more to meet the arch blast-resistant door of blast-resistant door force and deformation feature.Below a concrete example, so that the utility model is further explained to explanation.
Embodiment 1:
The blast-resistant door of this embodiment is comprised of doorframe and door leaf 1.
The basic structure of door leaf is made by the welding of girder steel skeleton and steel facing, and steel facing is the coated arcuate surface 2 that is finally formed with of steel frame, and when work, this arcuate surface 2 is directly met blast impulse.Steel frame is that three crosspieces and three vertical files are welded in length and breadth.Its middle rail is Curved beam, and this beam is to design according to the arch camber of arched door one side, the dull and stereotyped feature of one side, and the assembling that is conducive to door leaf is made, and specifically by three panels, is welded, and finished curved edges 3, the plane edge of a wing 5, web are 4, and crosspiece spacing is 270mm.With the steel facing of Curved beam finished curved edges welding with all adopt 10mm steel plate with the steel facing of Curved beam plane edge of a wing welding.
Four bearing pins and door lock have been assembled in one side of door leaf, and another side is equipped with four bearing pins.
Doorframe is Plate Welding rectangularity framework, corresponding with door leaf, and doorframe both sides are four pin-and-holes that coordinate with door leaf bearing pin of punching respectively, in pin-and-hole, can be equipped with guide; And one side of doorframe is provided with the pin-and-hole coordinating with door lock.
Claims (4)
1. a blast-resistant door, comprises door leaf, and this door leaf is provided with explosion-proof shock surface and the back side relative with being provided with explosion-proof shock surface, it is characterized in that, described explosion-proof shock surface is arcuate surface.
