Further, the right angle L-type profile includes the side being in contact with stair beam type part, and is mutually hung down with side Straight bottom surface, the surface mount of the bottom surface have the sheet for playing cushioning effect.

Further, between bottom surface and sheet, it is compressed with the noise reduction cotton for eliminating noise.

Further, there are several engraved structures on the bottom surface.

Further, the left beam form and right beam form surface are printed on the steel seal mark for distinguishing left and right directions respectively.

The utility model have the beneficial effect that the utility model makes the improvement is that it is whole using punching block, no In the beam type part for realizing beam type building using plank sheathing and foam insert.Relative to the prefabricated beam type of plank sheathing formwork, this reality With it is novel improve prefabricated precision and not requiring beam type one's duty inclination it is conveniently stripped and improve Prefabrication wheel number reduction Cost.The indent at stair both ends is realized relative to original the filling using foam of stringer type stairway, the utility model uses punching block Realization, which improves precision and saves cost and prevented secondary pour of stringer type stairway, smashes.Also, between adjacent mould parts It is additionally arranged plate, largely increases the efficiency of dismounting mold.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Appended drawing reference: left beam form 1, right beam form 2, upper internal model 3, upper internal model plate 4, core insert 5, core insert plate 6, overhanging Part 7 shores 8.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model 1, to the technical scheme in the embodiment of the utility model into Row clearly and completely describes, it is clear that and the described embodiments are only a part of the embodiments of the utility model, rather than all Embodiment.

A kind of stringer type stairway mold, comprising:

Beam form, beam form are divided into left beam form 1 and right beam form 2, and left beam form 1 and right beam form 2 are parallel to each other, the beam form be for The strip steel of cantilevered stairway beam type part；

Internal model, internal model are bolted on the end face of beam form, and the internal model is for cantilevered stairway built-in part Steel part；

Overhang part 7, the overhanging part 7 is the U-shaped steel material for cantilevered stairway beam type part, U-shaped steel material and beam form Tool is mutually perpendicular to place, and U-shaped steel surface has the bolt mounting holes for U-shaped steel material bolt to be fixed on to beam form top, U-shaped steel Material is bolted on beam form, and threaded hole of the multiple groups for cooperation, side can be arranged on beam form according to actual needs Just U-shaped steel material adjusts position.U-shaped steel material grows beam form part, the beam type portion as main cantilevered structure, for cantilevered stairway Point.

8 are shored, 8 is shored and is bolted between left beam form 1 and right beam form 2, play a supporting role, it is described to shore 8 For hollow square steel.Since certain extruding force can be generated in the casting process of beam type part, if not shoring 8 designs, beam form It may inwardly be tightened because extruding force is excessive, eventually lead to the beam type part deformation poured.

A kind of stringer type stairway mold, the internal model include upper internal model 3 and core insert 5, and upper internal model 3 and core insert 5 lead to respectively It crosses bolt to be separately fixed on the both sides of the face of beam form, upper internal model 3 is made of internal layer mold and outer layer mold, outer layer mold package In internal layer die surface, outer layer mold keeps internal layer mould not blocked by left and right beam as support construction, if internal layer mould surface is equipped with Dry for connecting the bolt hole of transition.Bolt is fixed mold by the bolt hole, after the completion of beam type part pours, is needed When to carry out tapping to mold makes it fall off, which can prevent the displacement generated during tapping.

A kind of stringer type stairway mold, the core insert 5 divide for left half module and right half module, press among left half module and right half module One block of plate, the plate are further secured among left half module and right half module by bolt, and core insert 5 is located at upper internal model 3 Other end, beam type part pours completion, when dismantling to mold, first by the disassembling bolts on plate, by plate crowbar It pulls out, then left half module and right half module is touched, disassembly can be completed.

A kind of stringer type stairway mold, the upper internal model 3 are fitted to each other place with beam form end face, are pressed between the two slotting Plate.Equally, when being dismantled to mold, first by the disassembling bolts on plate, plate is pulled out with crowbar, then light to upper internal model 3 It strikes, disassembly can be completed.

A kind of stringer type stairway mold, the plate, which is equipped with, is inserted into and agitates the through-hole of plate, the plate convenient for crowbar For rectangle sheet metal.Since plate is compacted sometimes, it is difficult to take out, need to pull out by crowbar.

A kind of stringer type stairway mold, the beam form are right angle L-type profile, and right angle bending place is welded with several for increasing Add the reinforced sheet of beam form bending strength, there is and shore the through-hole of 8 bolts assembly on the reinforced sheet.It can due to pouring beam type part Biggish pressing force can be generated to beam form, deformation occurs to avoid beam form, it is therefore desirable to further beam form is reinforced, Reinforced sheet is welded in beam form right angle bending place, and reinforced sheet plays the role of similar reinforcing rib.It can be placed equidistant with more according to actual needs Group reinforced sheet.

A kind of stringer type stairway mold, the right angle L-type profile include the side being in contact with stair beam type part, Yi Jiyu The perpendicular bottom surface in side, the surface mount of the bottom surface have the sheet for playing cushioning effect.Due to disassembly in disassembly process Tool and mold are very stiff and demanding relationship, therefore inevitably generate and damage to mold, thus to increase service life and number, Add sheet tapping position, plays buffer function.

A kind of stringer type stairway mold is compressed with the noise reduction cotton for eliminating noise between bottom surface and sheet.? During disassembly taps, there is biggish noise, therefore noise reduction cotton has been pasted between bottom surface and sheet.

A kind of stringer type stairway mold has several engraved structures on the bottom surface, in the case where not influencing beam form intensity, does Hollow design mitigates mold weight, convenient transportation and use.

A kind of stringer type stairway mold, the left beam form 1 and 2 surface of right beam form are printed on the steel for distinguishing left and right directions respectively Imprint, during practice of construction, it is often necessary to while multiple molds are used, left beam form 1 is identical with right 2 shape of beam form, only instead To on the contrary, to avoid construction personnel from selecting mistake, therefore in die surface printing steel seals mark.

It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms Type, therefore in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in All changes in justice and range are embraced therein.
