Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a step construction lofting mould for a stepped classroom. Background Art

[0002] Lecture halls are commonly found in universities and some primary and secondary schools. This type of classroom is large and can accommodate many people, but its biggest feature is that the floor is gradually raised in a stepped manner. The farther away from the podium, the higher the floor, and thus the higher the seats. This allows students who are far away from the podium to clearly see the blackboard and the podium without being blocked by the students in the front row.

[0003] like Figure 1 As shown, when constructing the steps of the lecture hall, it is necessary to build the ridge wall with non-clay solid bricks, then set up prefabricated panels on the ridge wall, and then lay the non-slip floor tile surface layer on the prefabricated panels. During the construction process, it is necessary to measure and lay out the lines to determine the position of the ridge wall. Due to the large number of lecture halls, manual measurement and positioning are time-consuming and laborious, resulting in serious delays in construction progress and affecting the construction period. Therefore, a lecture hall step construction layout mold has been developed to increase the speed of measuring and laying out the position of the ridge wall and speed up the construction period. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a step layout mold for the construction of a stepped classroom to solve the technical problems pointed out in the above background technology.

[0005] In order to achieve the above utility model purpose, the technical solution adopted is as follows:

[0006] A mold for laying out steps in a stepped classroom, comprising a mold body, the mold body comprising a rectangular plate-shaped main body portion, an upper end of the main body portion being integrally connected with a rectangular plate-shaped extension portion, and a side edge of the extension portion being flush with a side edge of the main body portion, six sides of the mold body are all provided with scale lines, and the mold body is provided with transverse control lines and longitudinal control lines, and the mold body is provided with a first handle for easy holding.

[0007] As a further improvement of the utility model, it also includes several height extension plates arranged along the height direction of the mold body, one end of the height extension plate is provided with a connecting protrusion, and the other end is provided with a connecting groove matching the connecting protrusion, and the bottom end of the mold body is provided with a card groove matching the connecting protrusion, and the connection between the height extension plate and the mold body is achieved through the cooperation of the connecting protrusion and the card groove, and the connection between multiple height extension plates is achieved through the cooperation of the connecting protrusion and the connecting groove.

[0008] As a further improvement of the present invention, the width dimension of the height extension plate is the same as the width dimension of the main body part, and the thickness dimension of the height extension plate is the same as the thickness dimension of the main body part.

[0009] As a further improvement of the present invention, a second handle is fixed on the height extension plate.

[0010] As a further improvement of the utility model, a through hole is provided on the first handle and the second handle, and a connecting screw is provided in the through hole. The connecting screw passes through the through holes on the first handle and the second handle in turn and is threadedly connected with a locking nut. The setting of the connecting screw can further enhance the connection strength between the several height extension plates and the mold body.

[0011] The beneficial effect of the utility model is that the utility model can improve the speed of measuring and setting out the position of the ridge wall and speed up the construction period. When in use, the horizontal control line and the vertical control line are arranged on the control mold body to coincide with the laser positioning line, and then the operator uses a marking pen to mark the wall along the circumference of the setting out mold to draw the position positioning line of the ridge wall. In addition, by setting a height extension plate, it is convenient to position the ridge walls of different heights. BRIEF DESCRIPTION OF THE DRAWINGS
