Ces trous de boulin de 20cm de côté passent complètement à travers l'épaisseur du mur et sont espacés d'1m à 1,4 m. Ils correspondent aux attaches des tirants de fixation en bois pour le coffrage du mortier.
Does it refer to 'tie beams'?

mounting bars/mounting rods
trous de boulin refer to an old time construction style.
The above should retain this old time way of calling these,.

spreaders
Strictly speaking, "tirants" work in tension, not compression, which is why they are generally metal, not wood. Wood works better in compressionfor the apparent purpose (keeping the sides of the formwork apart) and so I find it likely that these are spreaders.

"Small pieces of wood are cut the same length as the thickness of the wall and are placed between the forms to maintain proper distance between forms. These pieces are known as spreaders. The spreaders are not nailed but are held in place by friction and must be removed before the concrete covers them. A wire should be securely attached to each spreader so that the spreaders can be pulled out after the concrete has exerted enough pressure on the walls to allow them to be easily removed."

waler bars
Comme je le vois:
- Les trous de boulins traversants reçoivent des pièces horizontales qui en coffrage moderne seraient des tirants (tie-rods) comme l'explique Barbara, ou des écarteurs (spreaders) qui maintiennent la distance entre les coffrages avant de travailler en traction après le remplissage
- Perpendiculairement à ceux-là (donc dans le plan vertical) se trouvent les "tirants de fixation" à mon avis mal nommés, ça pourrait être des renforts de coffrage mais j'ai du mal à voir s'ils sont verticaux ou horizontaux (entre deux trous de boulins à la même hauteur ou superposés)?
En tous cas cette pièce de renfort de coffrage s'appelle "waler bar" (barre de traverse), voir page 38 de ce catalogue par exemple:

Discussion
On page 110, this paragraph gives me hope!!!
The presence of the putlog holes of the wooden
cross ties helps us to reconstruct the process of the
walls construction.

But then I wondered whether you're talking about the structure supporting a coffered ceiling, where "tie beams" might well be right.
