Description

Pedestal capable of improving appearance quality of bottom edge of T-shaped beam

Technical Field

The utility model relates to a prefabricated T roof beam pedestal, especially a pedestal that can improve T roof beam bottom edge appearance quality.

Background

With the continuous development of the national infrastructure career, bridge structures spanning terrains such as rivers, valleys and the like are also changed day by day, wherein the upper part of a bridge which is widely applied is constructed into a prefabricated T-shaped beam, a plurality of beam manufacturing pedestals are poured in a prefabricated beam field before the prefabricated T-shaped beam is constructed, and the beam manufacturing pedestals are used as bottom dies of the T-shaped beam on one hand and are convenient for demoulding of side dies of the T-shaped beam because the beam manufacturing pedestals are higher than the ground by a certain height on the other hand. In order to eliminate gaps between the side forms and the pedestal and avoid slurry leakage from influencing the appearance quality of the T-shaped beam, a C-shaped groove is usually formed in the positions of the left side and the right side below a steel plate at the top of the pedestal in construction, a compressible black rubber strip is respectively placed in the C-shaped groove, one part of the rubber strip is exposed outside the groove, and when the left side mold and the right side mold are installed, the exposed part of the rubber strip can be extruded, so that the rubber strip is expanded and deformed along the height direction, the deformed part of the rubber strip can be filled in the gaps between the steel plate at the top of the pedestal and the left side and right side form plates, and the slurry leakage can be effectively avoided when concrete is poured. When the C-shaped groove at the top of the pedestal is constructed, people often adopt channel steel, after the concrete of the pedestal has certain strength, a steel plate is laid on the top of the pedestal in a full-length mode to serve as a bottom die when a T beam is prefabricated, in order to fix the steel plate, the steel plate is often welded and connected with the side groove steel on the left and right sides of the lower portion of the steel plate, so that a row of protruding welding spots can be formed between the steel plate at the top of the pedestal and a channel steel gap, after the side die is installed at the moment, even if the gap between the side die and the pedestal can be filled with rubber strips, a certain gap still exists around the protruding welding spots between the channel steel and the steel plate, the rubber strips at the welding spots can be gradually worn and damaged, then the gaps around the welding spots are enlarged, when the T beam is poured, cement paste can flow into the gaps, after the die is removed, sawtooth lines. Meanwhile, the damage and the replacement frequency of the rubber strip in the construction process can be accelerated, the material cost is increased, and the construction progress is restricted to a certain extent.

Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified in conjunction with the accompanying drawings as follows:

referring to fig. 1 to 3, the pedestal capable of improving the appearance quality of the bottom edge of the T-beam comprises a pedestal foundation 1 and a pedestal 2, wherein the left side and the right side of the top of the pedestal 2 are respectively provided with an angle steel 4 with an outward opening, a T-beam bottom die 3 is supported and fixedly connected on the two angle steels 4, the T-beam bottom die 3 is horizontally arranged, the bottom of the T-beam bottom die is connected with the angle steel 4 through a welding line 5, and a groove-shaped structure with an outward opening is formed between the two angle steels 4.

In this embodiment, the angle iron 4 is preferably an equilateral angle iron. The side length of the angle steel 4 is 40-60 mm, and the thickness of the angle steel is 2.5-3.5 mm.

The above described stage is more specifically described as follows:

the pedestal foundation 1 is located below the ground below the pedestal 2 and used for dispersing load transferred by the self weight of the T beam and avoiding uneven settlement of the foundation, the pedestal 2 is located in the middle position above the pedestal foundation 1, the pedestal 2 is higher than the ground by about 46cm so as to facilitate die stripping of a side die, two ends of the pedestal 2 are respectively provided with a lifting beam hole with the length of 50cm and divide the pedestal 2 into 3 parts, namely, pedestal end parts 2-1, 2-3 and pedestal main bodies 2-2. The length of the left side and the right side of the top of the pedestal 2 is respectively provided with an equal-side angle steel 4, the top of the pedestal 2 is paved with a steel plate as a prefabricated T-beam bottom die 3, the T-beam bottom die 3 and the angle steel 4 on the left side and the right side below the T-beam bottom die form a C-shaped groove respectively, the C-shaped groove and the C-shaped groove are connected in a welding mode, and a welding line 5 is hidden below the T-beam bottom.

The working principle of the pedestal is as follows: after the construction of pedestal 2 is finished, in "C" groove that T roof beam die block 3 and its below both sides angle steel 4 formed, lead to long installation black rubber strip, the rubber strip is installed the back part and is exposed in "C" groove outside, and when the T roof beam side form was installed from the pedestal 2 left and right sides, because of the extrusion makes the partial rubber strip that exposes along direction of height inflation deformation, the clearance of T roof beam side form and pedestal 2 side can be filled by the rubber strip after the deformation this moment. Because the utility model discloses changed the channel-section steel into angle steel 4, so T roof beam die block 3 moves to the die block below with angle steel 4's welding seam by the die block outside, is located the cell type structure. At the moment, no welding seam exists between the T-shaped beam side die and the pedestal 2, and no gap caused by the welding seam exists, so that slurry leakage is avoided, and two side edges of the bottom surface of the T-shaped beam cannot form a sawtooth shape after the T-shaped beam is tensioned. The rubber strip can not be damaged in an accelerated manner due to the existence of the welding line, and the replacement of the rubber strip is reduced. And then guaranteed the construction quality of T roof beam bottom limit, practiced thrift steel and rubber strip, improved T roof beam construction progress.

Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is within the scope of the present invention.
