Hello
I am going to move an opening between an inner hall and the living room 34 cm as the kitchen is going to be enlarged. The opening is on the ground floor, above it there are four bedrooms and a bathroom. In one picture, you can see how I have opened to the left of a support, the opening is to be moved to the left.
The opening is in a load-bearing wall approximately in the middle of the house 3.6 m and 4.4 m from the exterior walls. The house is approximately 8 x 7 m in ground area, it is a two-story wooden house (from '53) with an attic.
The opening is 132 cm, above the opening there are currently two planks 5x19 cm; with a small gap fastened together with 9 boards on each side. The planks rest on two 95x45 mm studs nailed together on either side. And the opening is also roughly in the middle of the load-bearing wall.
Is it enough to put up two similar planks, just a little longer, with an additional wooden pillar?
I guess I should prop, two props on each side, studs above and below?
Grateful for any feedback.

You can create a so-called book spine as follows: place a plank, e.g., 45x195, on its flat side on the floor, 2.5-3.0m long, to be used as a base for a prop and jack, rent two arch props, place a similar plank or possibly two in the prop's forks, two assistants holding the props when placing the planks on their sides helps.
Helmet use applies to all involved.
Use a crank or hydraulic jack 1.5-2 tons and a post 75x75 or round timber, possibly an additional prop,
tighten the plank to the ceiling and unscrew the arch prop until you feel the wall is unloaded.
Now you can remove the beam and replace it with a longer one.
The new post you use to transfer the load must have a support in the joist and possibly even down to the basement. Good luck/MLj

Thank you very much for the response!
Just a few questions: you mean I need two supports on each side, right? Is a "valvstämp" a special type of support?
And I use the jack to simply press up the support's planks, before I lock the support?
Do you think it's enough to get two identical 5x19 planks, just longer, to support the whole thing? Or do I need laminated beams?

Hello!
I would start by unloading on one side first, meaning a total of two props. Place the prop as close to the wall as possible and on the side you are least concerned about with the ceiling, as there might be some imprint. Props can be rented from construction equipment rental services, adjustable height 2.2-3.0 with a fork at the top is common.
Lift gently with the jack while threading out the prop, it will creak a bit but that's okay. Work calmly and methodically.
I would replace the beam with two 45x220 K24 standing side by side, glued together with four-inch nails from both sides 2 pcs c300 so that the planks work together. This assumes that the wall frame is 90mm so the planks fit.
Planks side by side provide better support on the beams, not so jingling./MLj
