Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a door frame structure serving as an entrance / exit of a lead chamber or the like constituted by a partition.

(Prior Art) A lead plate is attached to the wall surface of the lead chamber to prevent X-rays from leaking to the outside of the room, and the lead plate is also attached to the door serving as the doorway and the door frame to which the door is attached. Has been done. The work of sticking the lead plate is not easy because the lead itself is heavy and soft, and it takes time for the small sticking area. Especially when it is a sticking work to a complicated place, it becomes more troublesome. 4a and 4b are a horizontal sectional view and a vertical sectional view showing a conventional type door frame. As shown in FIG. 4, the conventional door frame has a lead plate (a) attached to the door frame itself. There is. Further, the door frame is composed of two pieces of frame members (b), (c), (d), and (e) together with the vertical rail, and has a structure in which a reinforcing material (f) is combined inside. Since (a) must be attached to the reinforcing material (f) inside the frame materials (b) and (d), its workability becomes extremely low. In addition, since the lead plate (a) is not easily attached in this manner, the attachment state is poor, which causes quality problems such as variations in the thickness of the door frame.

(Purpose of the Invention) The conventional door frame structure with the lead plate thus stuck has the above-mentioned problems. The present invention is intended to solve this problem, and provides a door frame structure in which lead plates can be easily attached and the door frame can be easily assembled without lowering the strength of the door frame itself.

(Structure of the present invention) The door frame of the present invention facilitates the attachment work of the lead plate and considers the convenience of its assembly, and the lead plate is attached inside the frame material as in the conventional case. Without using a reinforcing member having an L-shaped cross section as a separate frame member, a lead plate is attached to the inside of the reinforcing member. A lead plate is attached to this L-shaped cross section reinforcing material in a separate step, and the L-shaped cross section reinforcing material to which the lead plate is stuck is only incorporated as one of the constituent members of the door frame assembly.

That is, the L-shaped cross-section reinforcing member is fixed to the stud and the horizontal crosspiece, and the vertical frame member and the horizontal frame member are fixed to sandwich a piece of the L-shaped cross-sectional reinforcing member to form a predetermined door frame. With the L-shaped cross section reinforcement fixed to the stud, another lead plate is attached from the stud to the L-shaped cross section reinforcement. The configuration in which the L-shaped cross-section reinforcing material is sandwiched between both frame members is the same for both the vertical and horizontal rails of the door frame.

Embodiments according to the present invention will be described below in detail with reference to the drawings.

(Embodiment) FIGS. 1 and 2 show an embodiment of a lead-containing partition door frame structure according to the present invention. FIG. 1 is a horizontal sectional view, and FIG. 2 is a vertical sectional view. In FIG. 1, 1 is a door, 2 is a door frame vertical rail, 3 is a door frame horizontal rail, 4 is a stud,
Reference numeral 5 denotes a panel, and 6 denotes a lead board. Here, the door frame to which the present invention is applied is the above-mentioned door frame vertical rails 2 and 2 and door frame horizontal rails 3.
3 is a gate-shaped frame, and the door frame vertical bar 2 is a cross section. Vertical frame material 7a and cross section of mold A vertical frame member 7b of a mold and a reinforcing member 8 having an L-shaped cross section are combined and configured. The reinforcing member 8 is screwed to a stud 4 which is vertically erected on a skirting board (not shown), and the vertical frame members 7a and 7b are screwed with another piece of the fixed reinforcing member 8 interposed therebetween. . FIG. 3 shows the reinforcing member 8 having an L-shaped cross section alone, and a lead plate 9 is attached to the inside of the reinforcing member 8. Although the work of attaching the lead plate 9 can be performed directly at the installation site, the lead plate 9 may be shipped after being attached at the factory. In the door frame structure of the present invention, the lead plate 9 is attached to the inside of the L-shaped cross-section reinforcing member 8 and the lead plate 10 for sealing between the reinforcing member 8 and the stud 4 after being fixed to the stud 4. It is attached. Lead plate 16 on one side of the stud 4
Is attached to the lead plate 16, and the lead plate attached to the back surface of the lead board 6 and the lead plate 10 are partially overlapped with each other. Here, the lead board 6 is a panel in which a lead plate is attached to one surface of a backing material such as a gypsum board and a surface material is attached to the other surface.

These vertical frame members 7a and 7b are attached to the stud 4 and the lead board 6 respectively.
A predetermined distance is provided between the side edge of the panel 5 and the side edge of the panel 5, and a joint 12 is fitted and screwed into the distance. On the other hand, the longitudinal cross section shown in FIG.
Is a cross section Cross section of the mold horizontal frame material 13a It is composed of a horizontal frame member 13b of a mold and a reinforcing member 14 having an L-shaped cross section. Here, the horizontal frame member 13a includes the vertical frame member 7a and the horizontal frame member 13b.
Is joined to the vertical frame member 7b to be framed, and therefore, their cross-sectional shapes are the same. Then, a lead plate 9 is attached to the inside of the reinforcing member 14 having an L-shaped cross section as shown in FIG. 3, and the reinforcing member 14 is screwed to the horizontal rail 15, and the space between the horizontal rail 15 and the reinforcing material 14 is secured. A lead plate 10 is attached to seal the. A lead plate 16 is attached to one surface of the horizontal rail 15 and the lead plate 16
Is a lead plate attached to the back of the lead board 6, and the lead plate 10
Are partially overlapped.

As described above, in the door frame structure of the present invention, each of the door frame vertical rail and the door frame horizontal rail is composed of one set of vertical frame member and horizontal frame member, and L-shaped cross-section reinforcing member, and the lead plate is the reinforcing member. Since it is attached only to the material, the following effects can be obtained.

(Effects) (1) In the door frame structure of the present invention, leakage of X-rays can be prevented by using an L-shaped cross-section reinforcing material and attaching a lead plate only to the reinforcing material. Therefore, its structure is simpler than the conventional structure, and the installation work of the door frame is particularly convenient. The work of attaching the lead plate to the L-shaped cross-section reinforcing material is simple, and the workability is improved because the lead plate can be incorporated in the attached state.

(2) Further, in this door frame structure, since the frame member is incorporated with one piece of the L-shaped cross-section reinforcing member sandwiched therebetween, the vertical and horizontal frame members are stable with the reinforcing member as a core, and the strength and rigidity are also increased.
