Description

One kind building door body structure

Technical field

The utility model belongs to technical field of buildings, and in particular to one kind building door body structure.

Background technology

The building door body structure of the prior art, its structure design are unreasonable, it is necessary to improve.

Utility model content

First, technical problems to be solved

The technical problem to be solved by the present invention is to provide one kind to build door body structure, to solve the technical problem.

2nd, technical solution

To solve the technical problem, technical solution is used by the utility model：One kind building door body structure, it has Have an exterior door frame, the exterior door frame with one dodge gate of hinge connection, has a doorframe in one in side in the dodge gate, it is described in In doorframe with hinge connection one can two-way keying inside door, the dodge gate has a cross section in the whole door side of adjacent hinge First protrusion of arc-shaped evagination, the whole frame side on the inside of the doorframe have the first recessed of a relatively arc-shaped indent Portion, first protrusion are inserted when dodge gate is closed in first recess, and are had between the first recess for living The gap of dynamic door pivot pendulum；The whole door side of the inside door both sides has the second protrusion of the arc-shaped evagination in a cross section respectively, The frame side of the interior doorframe both sides has the second recess of a relatively arc-shaped indent respectively, and each second protrusion is closed in inside door Correspond to and inserted in each second recess when closing, and have between each second protrusion and corresponding second recess for inside door pivot The gap of pendulum.

First protrusion and second protrusion are in arc-shaped.

First recess is oblique tapered inwardly by outside respectively with second recess.

3rd, beneficial effect

The utility model is compared to the prior art, has the advantages that：

1st, be designed as inside door can be therefore electronic when fire resistant doorsets towards bidirectional opening with closing for the door body structure of the utility model When rolling door and dodge gate are automatically closed, survivor still can leave scene of fire by inside door, if inside door in one opening direction by During resistance, it can still be opened and escaped by another opening direction.

2nd, the door body structure of the utility model is equipped with the first recess in exterior door frame, and to be correspondingly provided with one first convex for dodge gate Go out portion, therefore when dodge gate is closed, it is absorbed in by the first protrusion in first recess, and make flare can not be directly by Penetrated between one protrusion and the first recess, to reach effective fireproof effect.

Embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in detail.

As shown in Figures 1 to 5, the utility model provides a kind of building door body structure, it is applied to Fireproof door structure, Yu Ben The electric rolling door B sides of the fire resistant doorsets A are arranged in embodiment, the electric rolling door B and door body C is automatic when fire occurs Close, the door body C-structure includes：One exterior door frame 1, the exterior door frame 1 connects a dodge gate 2 in side with hinge 11, described There is doorframe 21 in one in dodge gate 2, an inside door 3 is connected with hinge 22 in the interior doorframe 21, the inside door 3 can bidirectional opening And close.

The dodge gate 2 has one first protrusion 23, first protrusion 23 in the whole door side of adjacent hinge 22 Cross section is arc-shaped and evagination, the whole frame side of the inner side of exterior door frame 1 has one first recess 12, first recess 12 The arc-shaped indent with respect to the first protrusion 23, it is recessed that first protrusion 23 inserts described first when dodge gate 2 is closed In portion 12, and there is the gap put for 2 pivot of dodge gate between the first recess 12.

The whole door side of 3 both sides of inside door has one second protrusion 31 respectively, second protrusion 31 it is crosscutting Face is arc-shaped and evagination, the frame side of interior 21 both sides of doorframe have one second recess 211 respectively, and each second recess 211 is opposite Second protrusion 31 and arc-shaped indent, each second protrusion 31 correspond to when inside door 3 is closed and insert each second recess There is the gap for 3 pivot of inside door pendulum in 211, and between each second protrusion 31 and corresponding second recess 211.

In this present embodiment, first protrusion 23 and second protrusion 31 are in arc-shaped, and described first is recessed Portion 12 is oblique tapered inwardly by outside respectively with second recess 211.

The major advantage of the utility model is：

1st, be designed as inside door 3 can be towards bidirectional opening with closing, therefore as fire resistant doorsets A for the door body C-structure of the utility model When electric rolling door B is automatically closed with dodge gate 2, survivor still can leave scene of fire by inside door 3, if inside door 3 is opened in one When opening direction and being obstructed, it can still be opened and escaped by another opening direction.

2nd, the door body C-structure of the utility model is equipped with the first recess 12 in exterior door frame 1, and dodge gate 2 is correspondingly provided with one First protrusion 23, thus when dodge gate 2 is closed, it is absorbed in by the first protrusion 23 in first recess 12, and make fire Seedling can not be directly by penetrating, to reach effective fireproof effect between the first protrusion 23 and the first recess 12.

Certainly, above-described embodiment can be subject to some changes in the case where not departing from the scope of the utility model, therefore the explanation of the above Whole items shown in included and attached drawing should be regarded as illustrative, and is not used to limitation the utility model and applies for a patent model Enclose.
