Description

Oblique split bolt for constructional column

Technical Field

The utility model relates to a fixing device of building constructional column template, especially a constructional column slant is to drawing bolt.

Background

At present, it is known that, in order to enhance the integrity and stability of a building, reinforced concrete constructional columns should be arranged in the wall body of a multi-storey brick-concrete structure building and connected with each layer of ring beam to form a space frame capable of resisting bending and shearing, which is an effective measure for preventing a house from collapsing. The arrangement positions of the constructional columns are at four corners of the outer wall, the joints of the cross walls and the outer longitudinal walls at staggered layers, two sides of a larger hole, the joints of the inner wall and the outer wall of a large room, and the like. The constructional columns comprise rectangular constructional columns arranged in the middle of a straight-line-shaped wall body and T-shaped, cross-shaped, L-shaped and other constructional columns arranged at the joint of the filling wall body. Through statistics, in the frame shear structure, the T font, the cross, about 40% of L shape wall body constructional column total number, because constructional column horse tooth raft is short (only 6cm), these wall body handing-over position constructional column templates can' T directly adopt traditional perpendicular to pulling screw rod mode to consolidate the constructional column template, the operating personnel need chisel the wall body and set up to carry out the template reinforcement to the stay bolt or adopt step by step tight, cause the situation such as brickwork damage around the constructional column, not hard up, fracture (especially add the influence of gas block infilled wall more serious), the whole impression quality of wall body is poor, the later stage needs secondary shutoff, and easily make the outer wall leave the infiltration hidden danger.

Known, CN 201720404389-super thick overlength shear force wall corner template support system slant short screw rod is to drawing device, including two support pads, two threaded sleeve, 1 slant short screw rod, two nuts, two support pad symmetries set up, two support pads are close to the perpendicular setting of end extension line, are equipped with the preformed hole on the support pad, slope on the support pad lateral surface that the preformed hole corresponds and set up the threaded sleeve, slant short screw rod both ends pass preformed hole, threaded sleeve and threaded connection nut on the support pad that corresponds in proper order. The constructional column formwork construction device can be suitable for the change of the thickness of an indoor wall body, the change of the positions of various indoor constructional columns and the change of the connection mode of the constructional columns and the wall. However, the reinforcing device is only reinforced by the diagonal short screw rods in one direction, and if the reinforcing device is tightened, the external corner is easy to deform and collapse; if the concrete structure is loosened, the phenomena of mold expansion and slurry leakage are easy to occur, so that the external corner of the corner cannot be effectively reinforced, and the concrete structure is only suitable for reinforcing the corner of the concrete structure (namely the L-shaped wall).
