Description

one

The invention relates to the construction, in particular to the structures of formwork for the erection of partitions of frame buildings.

The purpose of the invention is to reduce .. 5 labor costs, improve transportation and serviceability and increase the reliability of the connection of formwork panels.

Fig. 1 shows a formwork for concreting partitions, side view; in fig. 2 - the same, end view; Fig. 3 shows the support section in the folded state, a plan view; in FIG. 4, node 1 in FIG. one; FIG. 5 shows a section A-A in FIG. four; in FIG. 5. 6 is a section BB in FIG. four.

The formwork for concreting the partition walls of frame buildings consists of

set of formwork panels 1 and sections 2 of the supporting structures mounted on the fixing frames 3. Sections 2 of the supporting structure are parallelepiped of pipes that have hinges at the joints, through which sections can be folded as shown in Fig 3 for easy transport. Top - 1 parts 2 are her fingers that are included in the sleeves of the upper section 2. The striker 4 is welded to the upper girder of section 2 with pins 5 that enter into the openings of the shelves of the corners 6 of the formwork panels 1. The sleeve 7 is welded to the lower bolt of section 2 axis 8 installed in it, on which the handle 9 is rigidly fixed

in the form of a lever and an eccentric clamp 10, which interacts with a wedge stop 11 of the formwork shield 1. On the uprights of the supporting structures 2 rotary stops 12 are installed. The locking frames 3 have a structure welded from four corners and welded into them, supporting four screws, including adjustment screws 13 with ball bearing. Working platforms 14 were hung on the sections' sections,

Before the start of concreting, locking frames 3 are installed on one side of the concrete partition and on them a set of sections 2 of the supporting structure. By rotating the adjusting screws 13 with a ball spore on each fixing frame 3, the supporting structure 2 is fixed with an emphasis on the floor and the ceiling or upper beams, after which the formwork panels 1 are hung on the pins 5 of the slats 4 of the sections 2 across the entire height of the partition and fixed with eccentric bolts clamps 10. Likewise, sections 2 of the supporting structures on the other side of the partition, as well as the formwork panels 1 of the first lower tier, are fixed on the fixing frames 3. When concreting the lower tier, the remaining formwork boards 1 are held in the upper position by means of the pivoting stops 12 and, as the concreting of the tiers are lowered, installed in the design position and fixed by turning the handle 9 of the lever-eccentric locks, as required, working platforms are hung on the crossbars of the supporting structure sections 14.

Concreting is carried out with the help of a mortar or concrete pump, feeding concrete mix through the hoses into the gap between the fixed and suspended on the rotary support 12 opal

side shields 1. Upper rus is filled with concrete mix through holes in the upper shuttering shields. When dismantling the formwork by turning the handle 9, the lever-eccentric lock is moved to the inoperative position, and the adjustment screws 13 with ball support are screwed into the nuts of the fixing frames 3, the sections of the supporting structures are lowered, the pins 5 come out of the corners of the corners 6 of the shuttering boards 1, The sections 2 of the support structures are detached from the formwork boards 1 and from each other.

Then the sections 2 of the support structures are detached from each other, folded for ease of transportation and, together with the formwork panels 1 and the fixing frames 3, are transferred to the concreting site of the next partition.
