Detailed Description
With respect to the above technical solutions, preferred embodiments are described in detail with reference to the drawings.
Referring to fig. 1 to 3, the narrow space formwork reinforcing structure of the present invention includes two vertical side formworks 10 arranged at an interval, and the two side formworks are made of wood or metal. The upper and lower ends between the two side formworks are respectively connected and fixed through a telescopic device 20. The telescoping device 20 comprises an outer sleeve 21 and an inner sleeve 22 which are sleeved with each other, and scales are respectively arranged on the inner sleeve 21 and the outer sleeve 22. A plurality of fixing holes 23 are formed in the outer sleeve 21 and the inner sleeve 22 at intervals along the length direction, and the relative position between the outer sleeve 21 and the inner sleeve 22 is fixed by a pin shaft passing through the fixing holes 23. The periphery of the non-inserted end of the outer sleeve and the inner sleeve is respectively provided with a fixed connecting seat 211 and a fixed connecting seat 221. Generally, the outer sleeve and the inner sleeve are made of steel pipes. The fixed connecting seats of the outer sleeve and the inner sleeve of the telescopic device are respectively connected to the templates on the two opposite sides through screws and nuts.
Four corners at the upper and lower ends of the side mold plate 10 are respectively provided with a telescopic device 20, and the distance between the two side mold plates is adjusted by adjusting the insertion depth of the inner and outer sleeves of the telescopic device 20, so that the side mold plate adapts to the size of a narrow space.
The top of the side template 10 is welded and fixed with a lifting hook 30, and the lifting hook 30 is made of steel bars. Through holes are further formed in the side templates 10 close to the two side edge portions for the wall-penetrating screws to penetrate through, and the template reinforcing structure is prevented from moving through the wall-penetrating screws. Between the two sideforms there is located a bladder 40, the bladder 40 extending from the top of the sideform to the bottom of the sideform.
