Connection structure of beam and support member with bracket

The present invention relates to a small beam member joining structure composed of horizontal large beam members and fittings in the center of a large beam member, which can reduce required air, can exhibit sufficient bonding stress, and are easily joined with a vertical column. .

Recently, precast concrete (PC) members are frequently used in construction sites for air shortening and construction convenience. However, PC member is a problem of joining between members, and various structures and methods have been derived from related industries and academia to solve the joining problem between PC members. -By embedding the steel, many methods are used to make steel joints or pin joints between PC members while enhancing the flexural tensile stress of PC members.

However, steel joints or pin joints are inadequately fastened due to high precision and high-altitude operation, and there are problems in terms of safety management of workers.

The present invention is to improve both ends of the existing beam member to exhibit a sufficient bonding stress, to reduce the required bonding air, to improve the ease of operation at high places, so that the safety of disaster prevention can be exhibited,

The joining structure in which the horizontal beam member joining plate parallel vertical grooves are perpendicular to each other at right angles to the vertical grooves of the parallel protruding latches mounted at various joints, and the vertical grooves of the parallel protruding latches protruding from the center of the horizontal large beam member It is an object of the present invention to provide a joining structure in which a junction plate parallel vertical groove and a cross-fitting / hanging are perpendicular to each other.

Means introduced to solve the above problems are as follows.

1.Metal fastening means for horizontal and small beam members

Friction combined with both ends of large and small beam members consisting of precast concrete steel (S, R, C) beams reinforced with steel and reinforcing bars and ordinary steel (H-Beam) beams, or reinforced concrete PC beams The bonding plate is such that the vertical grooves of the parallel protruding latches at the joints such as the H-shaped pillars, the CFT pillars, the PC pillars, the RC pillars, and the retaining wall are fitted at right angles to each other.

It is a fastening process of parallel protruding fastening that connects the vertical and vertical grooves of the horizontal and small beam joints of horizontal and small beams vertically. Can be saved.

2. Means for sufficient bonding stress

(1) Installation of parallel protrusion latch

Precast concrete steel frame reinforced with steel and rebar is installed in such a way that parallel protruding clasps can be integrally fixed to H-shaped steel columns, CFT columns, PC columns, RC columns, and retaining walls. It is a parallel vertical groove of the joining plate which is joined to both ends of the large beam member and the small beam member composed of S, R, C) beam and ordinary steel beam (H-Beam) beam, or reinforced concrete PC beam member. And the joint structure in which the vertical grooves of the parallel protrusion latches mounted on the retaining wall and the joining portion and the vertical plate vertical grooves of the horizontal beam members are inserted at right angles to each other so that the parallel projecting latches and the joint plates of the beam members intersect. Will be exercised.

(2) Fixed chain installation to control deformation of parallel projecting latch

Bonding stress is exerted in the joining structure that controls the deformation caused by the stress variation of the parallel projecting latch by inserting the fixed chain from the upper part of the parallel projecting latch and joining the fixed chain into the upper horizontal groove of the projecting latch.

(3) Filling with void high strength non-contraction filler

Both ends of the horizontal beam members are joined to the joints such as H-beam columns, CFT columns, PC columns, RC columns, and retaining walls by parallel protruding and horizontal large beam members, horizontal large beam members and horizontal small beam members. The joint is composed of voids of about 15 to 20 mm for improving workability, and soft lakes having an outer diameter of 30 mm around the joint void where the voids are generated . Wrapped in a mold, the voids exhibit a bonding stress in the bonding structure to fill the high-strength non-shrink filler.

According to the present invention has the following effects.

1. In order to quickly assemble a horizontal member to a vertical member, it is possible to maintain a certain tolerance between the members, but the tolerance of the joining member is a fatal cause of a significant decrease in the joining force, so that an artificial gap of about 15 to 20 mm is formed. The voids are eliminated by filling the high strength non-contraction fillers, but the high-strength non-contraction fillers may be weaker in tensile strength than the compressive force. Install a fixed chain on the top of the clasp to remove the weakened tensile force.

2. The simple and quick joining structure in which the vertical groove of the parallel protruding latch and the beam plate of the horizontal beam member are mounted so as to cross at right angles to each other. By shortening the working hours, the safety and risk factors can be reduced.

The present invention is composed of precast concrete steel (S, R, C) beam and reinforced steel (H-Beam) beam, or reinforced concrete PC beam, reinforced plate reinforced with steel and reinforcing bars joined to block both ends of the member The joining plate has a joining structure in which parallel vertical grooves are formed so that the joining plates of the parallel projecting latches and the beam members intersect with the vertical grooves of the parallel projecting latches mounted on the joints such as the various columns and retaining walls. to provide.
