Embodiment 1

[0024] Embodiment 1: a kind of building formwork for fire climbing ladder, as figure 2 , including four support columns 3, a top plate 4 fixed above the support column 3, a fixed column 6 fixed below the top plate 4 and passing through the formwork unit 5, at least two formwork units 5, each formwork unit 5 comprising a U-shaped frame 52 , the fixing plate 51 , the connecting bolt 53 , the connecting bolt 53 passes through the fixing plate 51 and connects with the U-shaped frame 52 . The distance between two adjacent support columns 3 is greater than the corresponding length or width of the template unit 5 , so that the U-shaped frame 52 and the fixing plate 51 can slide out from between the two support columns 3 .

[0025] Such as Figure 3-4 A first horizontal bar 511 is fixed on the fixing plate 51, a second horizontal bar 521 is fixed on the inner wall of the U-shaped frame 52, and one end of the first horizontal bar 511 and the second horizontal bar 521 abuts and at th...

Embodiment 2

[0028] Embodiment 2: A construction method for a fire-fighting ladder: a construction method for a fire-fighting ladder, comprising the following steps: 1) pouring the base 2, pouring the bottom of the steel bar main body in the base 2, and pouring the bottoms of the four supporting columns 3 at the same time In the base 2, and a top plate 4 is welded on the top of the support column 3; 2) Put the bottom formwork unit 5, the bottom of the bottom formwork unit 5 is horizontal (the formwork unit 5 consists of a U-shaped frame 52 and a fixed plate 51 , connecting bolts 53, first connecting block 514, and second connecting block 524), pour concrete to the bottom of the first groove 513, put it into the upper formwork unit 5, and the first formwork unit 5 of the upper formwork unit 5 A horizontal bar 511 and a second horizontal bar 521 squeeze the concrete in the lower formwork unit 5, then pour the concrete to the bottom of the first groove 513 close to the formwork unit 5, and put...

Abstract

The invention discloses a building template for a fire ladder. The building template comprises at least two template units; each template unit comprises a U-shaped frame and a fixing plate detachablyconnected with the U-shaped frame; the fixing plate is fixedly provided with a first transverse bar arranged horizontally; a second transverse bar arranged horizontally is fixed to the inner wall of the U-shaped frame; one end of the first transverse bar abuts against one end of the second transverse bar; and the first transverse bar and the second transverse bar are located at the same horizontalheight. According to the set height of the fire ladder, the corresponding number of template units is designed, according to the pouring mode, one of the template units is placed, concrete is poured,then another template unit is stacked on the original template unit, then concrete is poured, and the steps are repeated until the fire ladder reaches the required height; after initial setting of concrete, the template units are dismounted, when each template unit is dismounted, the fixing plate is horizontally moved and dismounted at first, and then the U-shaped frame is horizontally moved anddismounted.

Description

technical field [0001] The invention relates to the field of idea ladder construction, in particular to a building formwork for fire-fighting ladders and a construction method thereof. Background technique [0002] The fire ladder is suitable for the daily training of firefighters. Firefighters often climb various floors, and the fire ladder is used for ordinary training. Its structure is as follows: figure 1 As shown, it includes a reinforced concrete column 1, and an L-shaped annular groove 11 is provided along the height direction of the reinforced concrete column 1, and stepping and climbing are performed through the annular groove 11. [0003] At present, the construction method of the fire ladder generally adopts the method of pouring up layer by layer, that is, the upper layer is poured after the concrete of the lower layer is solidified, and the pouring efficiency is relatively low. Contents of the invention [0004] In view of the deficiencies in the prior art, t...
