に設けた荷役装置によって養生室内に積卸される。[Conventional technology J] Conventionally, when forming concrete products, concrete placed in a formwork is transported to a curing chamber and heated at a predetermined temperature (approximately 80°C) for a certain period of time (1 week to 1 month). It is cured by drying. The formwork is integrally provided on a formwork truck, and is carried into the curing room together with this formwork truck. After pouring concrete, the formwork is loaded onto the car body together with the formwork truck, transported to the curing room, and unloaded into the curing room by a cargo handling device installed on the car body.

枠台車の搬入、搬出時に作業者がその都度子で開閉操作
している。After curing, the formwork truck is pulled out of the curing room, loaded onto the car body, and transported to the demolding process. The entrance to the curing room is usually closed by a door that can be opened and closed, and the worker manually opens and closes the door each time the formwork cart is brought in and taken out.
[発明が解決しようとする課題]
しかしながら、このような従来の養生室開閉扉において
は作業者が手で開は閉めしているため、その作業が面倒
で、しかも扉は重を物なため大きな操作力を必要とし、
作業者の負担が大きく、また誤って手を離すと危険であ
るという問題があった。[Problems to be solved by the invention] However, in such conventional curing room opening and closing doors, the operator has to open and close them by hand, which is a tedious task.Moreover, the door is heavy and has a large size. Requires operating power,
There was a problem in that it placed a heavy burden on the worker and was dangerous if the operator accidentally let go of the handle.
したがって、本発明は上記したような従来の問題点に鑑
みてなされたもので、その目的とするところは、比較的

A door opening/closing motor is installed on a column on the formwork carrier body that runs on a rail laid across the front, and the motor drives the door opening/closing motor to move up and down along the column. The door pushing member engages with the retaining portion from below to push up the door, and lowers the door when the door is lowered.
[作用]
本発明において、駆動モータの駆動によって扉押し上げ
部材を上昇移動させると、扉押し上げ部材が下から係合
部と当接して、これを押し上げる。[Operation] In the present invention, when the door push-up member is moved upward by driving of the drive motor, the door push-up member contacts the engaging portion from below and pushes it up.
したがって、扉も上昇し、養生室の入日を開く。Therefore, the door also rises, opening the daylight of the curing room.

(2) A driven sprocket 24 to which rotation of a driving sprocket 22 provided at the shaft 1 is transmitted via a chain 23;
A pair of left and right transmission sprockets 25 (25A, 25B) are attached to transmit the rotation of 9 to the sliders 14A, 14B. On the other hand, sprockets 26 (26A, 26B) are rotatably disposed at the lower ends of each of the pillar bodies 12A, 1.2B in correspondence with the transmission sprockets 25A, 26A, and these sprockets 25A, 25B, 2
An endless chain 27 (27
A, 27B) are stretched. Each end of the door pushing member 15 is connected to each of the endless chains 27A, 27B so as to be horizontal.
なお、扉開閉用モータ20を支柱12上に設置した理由
は、型枠台車11の搬入、搬出の邪魔にならないように
するためで、その限りにおいて他の適宜な場所を確保で
きる場合は上記位置に限定されるものではない。The reason why the door opening/closing motor 20 is installed on the support column 12 is to prevent it from interfering with the loading and unloading of the formwork cart 11, and to that extent, if another suitable location can be secured, it may be placed in the above position. It is not limited to.

の搬入を可能にする。Next, the operation of the curing chamber door r#4 closing/lid device having such a configuration will be explained. An entrance 3 of the curing chamber 1 is normally closed by a door 2. When the formwork cart transport body 10 stops in front of the curing room 1 to carry the formwork cart 11 into the curing chamber 1, the door push-up member 15 closely faces and engages with the door 2, as shown in FIG. The 0th order located directly below the section 4 drives the door opening/closing motor 20 and rotates its output shaft 21 through the drive sprocket 22 - chain 23 - driven sprocket 2
4-Transmission sprocket 25.26 and endless chain 2
7 to the door pushing member 15, the slider 1
4 rises along the support main bodies 12A, 12B, and the door pushing member 15 abuts on the retaining part 4 from below and pushes it up. Therefore, the door 2 opens as the door pushing member 15 rises, and when it is fully opened, it stops at the uppermost position by stopping the door opening/closing motor 20, allowing the formwork cart 1■ to be carried into the curing chamber 1. Make it.

反対方向に回転させると、今度は扉押し上げ部材15が
下降するためこれに保持されていた扉2も下降し、入口
3を再び閉める。After carrying in the formwork truck 11, when the door opening/closing motor 20 is rotated in the opposite direction to that described above, the door pushing member 15 descends, so the door 2 held by it also descends, and the entrance 3 is opened again. close.
したがって、扉2を作業者が手で直接開けたり、閉めた
りする必要がなく、安全で、作業者の負担を軽減させる
ことができる。Therefore, there is no need for the operator to open or close the door 2 directly by hand, which is safe and reduces the burden on the operator.
