Description

Truss support and formwork using same}

The present invention relates to a truss support and a formwork using the same, and more particularly, to a truss support, which is a constituent member of a formwork installed for slab construction, and a formwork using the same.

In general, the slab construction of a steel-framed concrete structure consists of installing a formwork for the slab, reinforcing reinforcement and pouring concrete, and curing it.When the concrete curing is completed, the formwork is dismantled and reused.

Since the above-described formwork is installed by combining various types of constituent members such as upper and lower plates, horizontal and vertical support members, and auxiliary members, it not only has a problem that a lot of time is required for installation work and dismantling for reuse. Since the shape, size, and dimensions of the slab structure are different for each construction, there is a problem in that the structural members of the formwork cannot be standardized and used in a certain form.

As a prior art related to a formwork for slab construction, for example, in Patent Document 1, a pair of first upper members parallel to the horizontal direction, a first lower member located in the lower center of the first upper member, and the first A first fixing member connected to the junction at one end of the upper member, a second fixing member connected to the first lower member at the junction, a fitting hole formed in a direction perpendicular to the junction, and a first lower member at the first upper member At least one first truss member connected in an inverted pyramid shape, a first connecting member coupled to the first upper and lower members to connect the first truss member, and installed connected to the first upper member in a longitudinal direction A main truss comprising a first support member and plywood coupling holes formed at both ends of the first support member; The second truss member is connected to the upper coupling part in the shape of an inverted pyramid from the second lower member and the vertical width is selected, and the second truss member is vertically connected to the coupling part and to the first upper member and the first connecting member of the main truss. A sub-truss comprising a plurality of second support members connected and installed in parallel in a vertical direction, and a second connection member installed on the second lower member; A truss formwork including a third connection member connecting the second connection member to the first lower member of the main truss is disclosed, and in the formwork frame in Patent Document 2, height adjustment is possible, and A first pair of frame members disposed along an edge and facing away from each other, and a first pair of frame members facing each other perpendicularly to the first pair of frame members, and the upper end thereof is more than the first pair of frame members. A frame member 100 having a second pair of lower frame members; It is vertically coupled to the first pair of frame members at the same height as the second pair of frame members between the first pair of frame members, and includes a second extension coupling portion for length extension at an end portion in the length direction, and height adjustment Possible auxiliary member 200; A connection member 300 coupled to the first extended coupling portion or the second extended coupling portion at an end portion in the longitudinal direction and coupled between the frame members or the auxiliary members; A formwork frame having a truss structure is disclosed, including a joist member 500, which is coupled to an upper portion of the auxiliary member and the second pair of frame members and has an upper end equal to the height of the first pair of frame members. Since many components of the formwork are required, the problem of taking a lot of time for installation work and dismantling work is still not solved.

The inventor of the present application completed the present invention by reducing the components of the truss support to improve the installation work and dismantling work, and at the same time weaving a truss support capable of stably installing a formwork.
