Description

  The present invention relates to a slope installed at an entrance of a warehouse such as a prefabricated refrigerator, a freezer or a storage.

  Generally, for example, a warehouse such as a prefabricated refrigerator, a freezer, or a storage is installed on the ground via a concrete base or the like, so that a step is generated between the floor of the warehouse and the ground. Therefore, slopes are used for loading and unloading luggage at the entrance of the warehouse.

  As this type of conventional slope, the front end is placed on the floor side edge of the warehouse and is placed on the rear end of the first tread structure panel (hereinafter referred to as the first panel) arranged in an inclined state. What comprises the tread board structure 2nd panel connected so that movement is possible is known (for example, refer to patent documents 1).

  The one described in Patent Document 1 is an inclination angle by selectively fitting two legs having different heights provided at the front part of the first panel into a recessed part provided at a floor side edge of a warehouse. When the height of the floor side edge is high, the inclination of the first panel is changed by the height-adjustable support mechanism provided at the rear end of the first panel. Yes.

It is comprised with the tread board member 30 constructed. In this case, the step main body 10, the floor member 20, and the tread member 30 are each formed of an extruded aluminum member.

  Further, height adjusting bolts 40 are attached to both ends in the longitudinal direction of the lower portion of each step body 10 of the step portion 5. By adjusting the height adjusting bolt 40, the tread member 30 of the step portion 5 can be adjusted in parallel to the height of the floor surface of the warehouse 2.

  As shown in FIG. 9A, the step body 10 is formed in a substantially T-shape including a horizontally long hollow rectangular upper portion 11 and a vertically long hollow rectangular lower portion 12. In addition, a screw pocket 7 having a substantially C-shaped cross section is formed in a longitudinal direction at a lower corner portion outside the upper portion 11 (outside the opposed step body 10). Further, a screw pocket 7 having a substantially C-shaped cross section is formed in a longitudinal direction at a lower corner portion inside the lower portion 12 (inward with respect to the opposed step body 10).

  The upper portion 11 is formed with a support portion 13 that sandwiches the floor member 20 between an upper support piece 13a and a lower support piece 13b extending in a horizontal direction from one side surface (inner side surface). In this case, in order to support the floor member 20 in a stable state, the lower support piece 13b is formed longer than the upper support piece 13a.

Also, a mounting wall 15 that locks the side wall 33 of the tread member 30 is formed by a locking wall 14 that rises perpendicularly to the other side surface (outer side) of the upper end portion of the upper portion 11 and the upper end surface.
An arcuate groove 14a having a narrow opening is formed on the outer surface of the locking wall 14 in the longitudinal direction. An arcuate ridge 62 projecting from a slope flooring 60 </ b> A constituting the slope portion 6, which will be described later, is rotatably fitted in the arcuate groove 14 a of the locking wall 14 provided in one step body 10. Is done. Further, a round bar-like backup material 16 is fitted into the arcuate groove 14 a of the locking wall 14 of the other step body 10.

  As shown in FIG. 9B, the floor member 20 has a central hollow portion 22 and left and right hollow portions 23 and 24 partitioned by two partition walls 21, and a hollow rectangular plate in which the lower portions of the left and right hollow portions 23 and 24 are opened. It is formed in a shape. A screw pocket 7 having a substantially C-shaped cross section is formed in the longitudinal direction at the upper position where the left and right hollow portions 23 and 24 face each other.

  As shown in FIG. 9C, the tread member 30 has side walls 33 on both sides in the width direction of the top plate 32 having anti-slip ridges 31 parallel to each other on the upper surface, and the top plate 32 extends from the center to both side walls 33. The lower surface of the top plate 32 is formed in an arc shape so as to gradually increase in thickness. In addition, the lower end of the side walls 33 is provided with a ridge 33a orthogonal to the inside. Further, screw pockets 7 having a substantially C-shaped cross-section opening outwardly are formed in the longitudinal direction at positions opposite to the left and right of the side walls 33.

Is screwed into an auxiliary fixing seat 93 a extending from a fixing seat 93 fixed to the tread member 30, and is suspended from the upper surface of the tread member 30.

  In the second embodiment, the other parts are the same as in the above embodiment, and therefore the same parts are denoted by the same reference numerals and description thereof is omitted.

According to the slope 1 of the said embodiment, the step part 5 is changed by changing the floor member 20 supported between the step main bodies 10, and the tread board member 30 by which both ends are latched by the upper end part of the step main body 10, and constructed. Therefore, it is possible to install the step unit 5 corresponding to the entrance / exit and the warehouse 2 of a different size.
Further, by adjusting the height adjusting bolt 40, the step part 5 can be made parallel to the height of the floor 2b of the warehouse 2, so that the height, type, refrigerator, freezer, storage, etc. It can also be used for the warehouse 2 and can safely load and unload luggage.

  In addition, a concave portion 17 having a narrow opening is provided in the lower portion of the step body 10 so as to extend downward, and a height adjusting bolt 40 is screwed into a nut 41 inserted into the concave portion 17 for height adjustment. Since the bolt 40 is attached, the height adjusting bolt 40 can be easily attached to an arbitrary position below the step body 10.

  Further, the surface of the tread board member 30 is prevented from freezing by inserting the anti-freezing heater H into the space 5a formed between the step body 10, the floor member 20, and the tread board member 30. Can do. In this case, the tread board member 30 is formed such that the central portion of the top plate 32 is thinned, both sides are gradually thickened, and the bottom surface of the top plate 32 is formed in an arc shape. The heat receiving area can be increased, and the heat conduction at the center of the top plate 32 can be improved.

  Further, an arcuate ridge 62 projecting from a slope flooring 60A constituting the slope portion 6 is rotatable in an arcuate groove 14a provided on the locking wall 14 of the step body 10 constituting the step portion 5. By fitting in, the fluctuation | variation and level | step difference of the connection part of the step part 5 and the slope part 6 can be prevented. As a result, it is possible to ensure the safety of loading and unloading work.

  Further, the slope tip member 60D that is grounded to the ground constituting the slope portion 6 is formed in a triangular shape, and the arc-shaped recess 60g provided in the side wall 60i of the slope tip member 60D projects into the side wall of the slope tip connection member 60B. A step formed between the step portion 6 and the ground 3 can be prevented by fitting the provided arcuate ridge 60f so as to be rotatable. As a result, it is possible to ensure the safety of loading and unloading work.

  Further, a guide roller 90 is provided on the upper portion of the tread plate member 30 so as to be pivotably in contact with the outer surface of the slide door that opens and closes the entrance 2a of the warehouse 2, and a stopper 91 that abuts when the slide door is closed. When the sliding door is provided at the entrance 2a of the warehouse 2, the sliding door can be opened and closed smoothly, and the sliding door can be reliably closed.
