Abstract

The shore (1) consists of a post (2) that is placed against the side brim of the wall opening (5), a cross-beam (3) fixed on the top of the post (2) and of which one end (4) is inserted into a to be pointed joint (A) between the building stones, an in height adjustable means (8-9) mounted on mentioned cross-beam (3), and a support (13-14) mounted on mentioned adjustable means and destined for carrying the girder (17), fitted in the wall opening. <MATH>

Description

  • The invention is for a shore designated for supporting a girder in a wall opening made in brick or blockwork masonry.
  • A shore is known from French patent FR-A-2002818 for supporting the horizontal girder of concrete formwork or scaffolding which shore comprises a post, which is jacked up against the wall, a means which can be adjusted in height with respect to the post, a support attached to said adjustable means for holding the girder.
  • This shore is nonetheless not suitable for supporting a girder in a wall opening, which wall is made in brick or blockwork masonry, without providing holes and bolts in the masonry to hold the shore against the wall.
  • A shore is likewise known from French patent FR-A-681943 and consists of a vertical post which is set up against the side edge of a wall opening and provided at the side and at a distance from the lower end with a horizontal crosspiece which is inserted in a joint between the bricks or blocks, and where a projecting slanting arm with a holding piece is attached by a pirot to the upper end of said post for holding the girder in the opening in the wall and where between said post and arm a removable adjusting wedge is inserted for maintaining said arm with holding piece in the desired position with respect to the post.
  • The main disadvantage of this shore is that because the pivoting arm projects at an inclined angle the post and arm are subjected to a bending force, particularly when heavily loaded, with the result that excessive bending and even failure of the shore may occur. Moreover the shore consists of a relatively large number of pieces, which has an adverse effect on its price. Other disadvantages are that the relatively complicated construction means that the shore is not easy to use, that the adjusting wedge may come loose, and that it is not possible to set the position accurately of the holding part which holds the girder.
  • It is an object of the present invention to obviate the aforesaid problems. This object is achieved by a shore according to claim 1.
  • As an example, a more elaborate description of a chosen in no way restricted form of execution of the shore in accordance with the invention follows hereafter. This description refers to the included drawing, in which:
    • fig. 1 respresents a perspective of the shore;
    • fig. 2 represents a side-view of the shore, fitted in a wall opening.
  • One notices in these figures, that shore 1 consists of a flat post 2 On which a flat cross-beam 3 is attached in such a way, that a T-shaped element is obtained. One end 4 of the cross-beam 3 has a thickness that is a little smaller than the width of the joints A between the building stones which border the wall opening 5. The other end of the cross-beam is provided with an opening 6 and a nut 7 welded to it, in which a tightening screw 8 can be adjusted in height. The lower end of the tightening screw is provided with a grip 9, and on the upper end of it, two nuts 10-11 are welded to it at some distance, between which a horizontally pivotable U-shaped support 13, supported by washer 12 is mounted. On the upper part of this support, a carrier 14 is fixed, which is provided with openings 15, and on which by means of wood screws 16, a girder 17 can be attached.
  • For the purpose of supporting a girder 17 to be placed in wall opening 5, one places a shore 1 to each side of the wall opening. For this purpose, one inserts the end of the cross-beam 3 of each shore 1 into a joint A of the masonry, until the post 2 rests against the side brim of wall opening 5. Subsequently, one places the girder 17 on the carrier 14 of the support 13 of each shore 1, one tightens tightening screw 8 of each shore, until the girder 17 is placed at a sufficient distance to the upper part of the wall opening in order to place the chanferred building stones, and one preferably attaches the girder to the carrier 14 of the support 13 of each shore, by means of wood screws 16. The later removal of the shores 1 takes place in reversed order.
