Abstract
A triangular truss screed includes first and second vertically oriented end brackets coupled to the first and second ends of the screed frame. Each end bracket includes front and rear vertically extending, spaced apart side members. A detachable guide bracket can be coupled to one of the screed end brackets for the purpose of supporting and guiding one end of the screed along a horizontally oriented guide member coupled to the wall of a building at a vertical position well above the concrete surface. The guide bracket includes first and second spaced apart side members which are detachably coupled to a screen end bracket. The guide bracket includes guide elements which laterally extend from the guide bracket to engage the wall-mounted guide member.
Claims8
A screed for leveling freshly poured concrete lying in an area between opposing side forms to produce a smooth, finished concrete surface, said screed comprising:
- a. a triangular truss frame having first and second ends and a top support member forming the apex of said triangular truss;
- b. front and rear screed blades coupled in a spaced apart relationship to the lower portion of the front and rear of said frame for leveling the upper surface of the concrete;
- c. first and second vertically oriented end brackets coupled to the first and second ends of said frame and including front and rear vertically extending, spaced apart side members, said first and second end brackets including an upper section extending above said top support member;
- d. a detachable guide bracket coupled to said first end bracket for supporting and guiding one end of said screed along a horizontally oriented guide member coupled to the wall of a building at a selected vertical position well above the concrete surface, said guide bracket including:
- i. a first vertically oriented side member including an upper section;
- ii. a second vertically oriented side member spaced apart from said first side member by a distance equal to the spacing between the front and rear side members of said first end bracket and including an upper section;
- iii. means for detachably coupling said first and second side members of said guide bracket to said first end bracket of said screed, whereby the upper sections of said first and second side members of said guide bracket extend above the top support member of said screed;
- and
- iv. guide means laterally extending from the upper sections of said first and second side members of said guide bracket for contacting said guide member to support the first end of said screed at a predetermined desired vertical position as said guide bracket is laterally translated along the length of said guide member;
- whereby the weight of the first end of the screed is transferred from said first end bracket through said guide bracket to said wall-mounted guide member to support the weight of the first end of said screed at a level above the top support member of said screed.
A screed for leveling freshly poured concrete lying in an area between opposing side forms to produce a smooth, finished concrete surface, said screed comprising:
- a. a triangular truss frame having first and second ends and a top support member forming the apex of said triangular truss;
- b. front and rear screed blades coupled in a spaced apart relationship to the lower portion of the front and rear of said frame for leveling the upper surface of the concrete;
- c. first and second vertically oriented end brackets coupled to the first and second ends of said frame and including front and rear vertically extending, spaced apart side members, said first and second end brackets including an upper section extending above said top support member and including a horizontal strut extending between said front and rear side members within the upper section of said bracket to maintain a predetermined horizontal spacing therebetween;
- d. a detachable guide bracket coupled to said first end bracket for supporting and guiding one end of said screed along a horizontally oriented guide member coupled to the wall of a building at a selected vertical position well above the concrete surface, said guide bracket including:
- i. a first vertically oriented side member including an upper section;
- ii. a second vertically oriented side member spaced apart from said first side member by a distance equal to the spacing between the front and rear side members of said first end bracket and including an upper section;
- iii. a spacing member coupled to the first and second vertically oriented side members within the upper section of said guide bracket for maintaining a predetermined horizontal spacing therebetween, said spacing member further including a lip extending under and around the horizontal strut of said first end bracket for locking together the horizontal strut of said guide bracket and the spacing member of said first end bracket;
- iv. means for detachably coupling said first and second side members of said guide bracket to said front and rear side members of said first end bracket;
- and
- v. guide means laterally extending from the upper sections of said first and second side members of said guide bracket for contacting said wall-mounted guide member to support the first end of said screed at a predetermined desired vertical position as said bracket is laterally translated along the length of said guide member,
- whereby the weight of the first end of said screed is transferred from said first end bracket through said guide bracket to said wall-mounted guide member to support the weight of the first end of said screed at a level above the top support member of said screed.
