Definitions

  • the invention relates to a method for arranging raw mate­rials for masonry at a place of work, wherein the height at which the raw materials are arranged is adjusted depending on the progress of the masonry operation.
  • the present invention therefore has for its object to provide a method of the above described type wherein the above mentioned drawbacks do not occur.
  • the invention further relates to a device for height-ad­justable arranging of raw materials for masonry, comprising a support part and a lifting part.
  • the present invention therefore has for a further object to provide a device of the heretofore described type wherein the above stated drawbacks do not occur.
  • This is achieved according to the invention in that the support part and the lifting part are releasably connected to one another.
  • the support part has the form of a so-called scissor table a device is obtained that is simple and light of con­struction.
  • the scissor table preferably comprises at least two mutu­ally connected scissor parts arranged at an interval from one another.
  • the loads on the scissor table are hereby dis­tributed whereby excessive deformation and jamming of the scissor parts are avoided.
  • the lifting part can also be detached when the scissor table is situated in the fol­ded-out position.
  • the device can thus be used with fewer lifting parts than there are support parts present, which has a considerable cost-saving effect.
  • the scissor table preferably has a base and the fixation means comprise fixation hooks connected to the scissor parts and co-acting with fixation pins attached to the base.
  • the lifting part comprises a frame releasably con­nected to the base and a lifting member arranged movably on the frame and connected releasably to the top of the scissor table, and the frame further has a chain winch mechanism and the lifting member comprises a toothing releasably connected to the chain, the lifting member can be rapidly set at the correct height prior to connection to the table top.
  • a place of work 1 (fig. 1) are various height-­adjustable support parts 2 for arranging raw materials for masonry work, namely bricks 3 and mortar 4. Further present at the place of work 1 is a lifting part 5 which can be re­leasably connected to a support part 2 in order to carry the support part 2 to the desired height. When a support part 2 has been placed at the desired height it can be fixed there­on.
  • a mason works with bricks 3 and mortar 4 from one of the support parts 2 at a time.
  • the remaining support parts 2 not in use are meanwhile filled by a so-called hod-carrier with bricks 3 and mortar 4 and carried using the lifting part 5 to the desired height.
  • the support part 2 has the form of a scissor table (fig. 2) with a base 6, two scissor parts 7 arranged at an inter­val from one another and a table top 8.
  • the scissor parts 7 are mutually connected by connecting means 9.
  • the support part 2 is further provided with means for fixing the scissor parts 7 in a number of positions consisting of a number of fixation pins 13 attached at an interval from one another to the base 6 and two fixation hooks 14 connected mutually and to the scissor parts 7.
  • a line 15 enables disengaging of the fixation hooks from the fixation pins 13.
  • the form of the fixation hooks 14 is such that they cannot be disengaged when the top 8 of the scissor table is loaded.
  • tow wheels 10 are arranged on the base 6 and the table top 8 is provided with a hand-grip 11.
  • the base 6 is also provi­ded with a foot support 12.
  • the lifting part 5 comprises a frame 16 connected releas­ably to the base 6 and a lifting member 17 arranged movably on the frame 16 and for releasable connection to the top 8 of the scissor table.
  • Both the frame 16 and the lifting member 17 are L-shaped.
  • Their lying parts 18, 19 can be placed in engagement with tubular profiles of the scissor table respectively forming a part of the base 6 and of the top 8.
  • the lying part 19 of the lifting member 17 forms a small angle with the surface of the top 8 in order to trans­fer the loads acting on the support part 2 uniformly onto the lifting part 5.
  • the frame 16 has a chain winch mechanism 20 and the lifting member 17 comprises a toothing 22 (not shown here) for releasable connection to the chain 21 of the mechanism 20, which toothing can be placed in or out of engagement with the chain 21 by means of the control member 23.
  • Fig. 3 shows the support part 2 in collapsed state.
  • the scissor table 2 has a number of folded-out positions (fig. 4), which are determined by the position of the fixation pins 13 on the base 6.
  • the folded-out positions of the scissor table are selected such that they each corres­pond with an optimum working posture for a mason.
  • Suitable heights of the table top 8 above the ground are for instance 65 cm, 45 cm, 30 cm and 12 cm.
