Description

{Support fixture for truss girders installation}

The present invention relates to a support for installing a truss girder together with a deck plate, more specifically, a deck plate is fixed to the lower part and a truss girder is fixed to the upper part, The present invention relates to a support for installing a truss girder.

Conventionally, a concrete structure of a ceiling slab is constructed by placing a reinforcing bar in a formwork having a plurality of formwork boards formed with a certain standard, placing the concrete therein, and disassembling the formwork when the concrete is cured.

This method of using the formwork is not only troublesome but also inconvenient for storing and transporting the formwork for reuse, and the construction period is also prolonged.

An improved structure for installing a truss girder from this structure has been proposed.

An example of a fixing structure of a truss girder for installing a deck plate is disclosed in Korean Patent No. 10-0894808. The truss-girder connector has a "C" -shaped fitting groove formed in the lateral direction so that the lower bolt of the truss-girder can be fixed to the lower panel by screwing the fixing bolt to the lower part of the connector body. It can be installed.

The fixing bolt is screwed to the lower part of the body and the lower reinforcing bar of the truss girder is fitted to one side of the upper part of the connecting body in a lateral direction so that the lower part of the lower plate has to be fixed with the fixing bolt, There is a problem that it is very inconvenient to work because the lower reinforcing bar must be joined to the side of the connector.

Another example of a truss girder fixing structure is disclosed in Korean Patent No. 10-1202377.

This truss girder integrated deck plate is characterized in that a reinforcing protrusion is formed in the deck panel in the longitudinal direction so that a truss girder can be coupled to an upper portion of the deck panel, Wherein the truss girder is welded to both sides of the upper reinforcing bar, and the lower reinforcing bars are respectively welded to the lower outer side of the lattice material, and a lattice foot formed on a lower portion of the lattice material of the truss girder, Wherein a reinforcing bar is coupled to an upper reinforcing bar and a lower reinforcing bar constituting a truss girder at both ends in the longitudinal direction of the deck plate so that the upper bent portion of the reinforcing bar is welded to the upper reinforcing bar, And the lower bending portions on both sides of the upper bending portion are lower And the lower connecting portion of the hooking bending portion is welded and coupled to the deck panel, respectively.

In such a structure, a reinforcing protrusion should be formed on the deck panel so that the truss girder can be coupled to the upper part of the deck panel. Since the truss girder is formed with a lattice foot from the lattice material so that the truss girder can be coupled to the reinforcing protrusion, The structure of the girder is very complicated, and the deck panel and the truss girder are fixed by the welding operation, so that the work process in the field is difficult.

[Patent Document 1] KR 10-0894808, Apr. 17, 2009 [Patent Document 2] KR 10-1202377, November 16, 2012

The present invention provides a truss girder which can be installed without a welding operation or a separate fastener, thereby improving the workability and reducing the construction cost

Technical features of the present invention to achieve the object of the present invention are as follows: a pair of vertical portions are formed so as to be parallel to both sides of a horizontal portion in contact with a deck plate in which holes for inserting screws for fixing the deck plate are formed, And a fixing groove in which a lower seal of the truss girder is inserted and supported from the upper surface of the vertical portion is formed.

Another feature of the present invention to achieve the object of the present invention is that a pair of vertical portions are formed in parallel to each other from both sides of the horizontal portion and a plurality of fixing grooves are formed through the lower surface of the truss girder, And the vertical portion is formed so as to extend further downwardly of the horizontal portion so as to fix the deck plate.

Wherein the fixing groove is formed to have an inner diameter equal to the diameter of the lower hook of the truss girder from the guide groove guiding the truss girder which is opened and inserted from the upper surface of the horizontal portion, And the inclined surface is formed to be smaller than the diameter of the lower barrel from the entrance formed to be larger than the upper barrel.

A groove is formed between the guide groove and the fixing groove so as to be opened from the upper surface of the horizontal portion, so that the groove can be elastically deformed.

In addition, the horizontal portion may have a plurality of locking protrusions, which can be folded with a plurality of locking projections, so that the ceiling panel can be used.

According to the present invention, the truss girder can be guided by the guide grooves to reach the fixing grooves, wherein the guide grooves are formed in a shape of a light beam so as to be continuous with the fixing grooves smaller than the diameter of the lower hook of the truss girder So that the truss girder inserted in the fixing groove is not arbitrarily detached.

The supporting rods of the truss girders according to the present invention can be used not only in fasteners such as fastening screws, bolts, or fastening wires, as well as fasteners such as fixing screws, The truss girder can be firmly installed even if the work is not performed. There is an advantage that the deck plate and the ceiling panel can be selectively installed.

The features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

Hereinafter, embodiments of the present invention will be described.

1 to 8 show drawings related to the first embodiment of the present invention.

As shown in this drawing, the supporting stand 1 for installing a truss girder according to the present invention is formed with a pair of vertical portions 11 and 11a arranged in parallel from both sides of the horizontal portion 10.

In the horizontal portion 10, a plurality of holes 100 and a carrying fixing portion 102 are formed at regular intervals.

The hole 100 can be inserted into the deck plate 2, or the screw 101 for fixing the die, so that it can be fastened to the deck plate or the die.

The carry fixing portion 102 is formed of a bent portion 104 and locking protrusions 105 and 105a formed by a punching groove 103 formed by press working.

The bent portion 104 is formed to have a narrower section than the end of the carrying fixing portion 102 by the concave grooves 106 and 106a formed by the punching groove 103 so that the bent portion 104 can be easily bent by hand It becomes possible to rotate the carry fixing part 102. [

A plurality of locking protrusions 105 and 105a are formed on both sides of the carrying fixing part 102 in a continuous manner.
