Abstract

This is a door-shaped counterforce rack used for the structure test. The door shaped frame is composed of the two vertical columns and the crossbeam between the two vertical columns. The vertical columns adopt H formed steel. The rack is characterized in that the crossbeam is mounted on the flange slab of the H formed steel vertical column. Along the vertical orientation, a plurality of the column bolt hole units are set on the flange slab of the vertical column for the adjustment of the crossbeam's different mounting height. Also, the crossbeam is arranged with a plurality of the transom bolt holes for different spans. This utility model makes the height and the span of the door-shaped counterforce rack adjustable, so as to achieve a strong load-carrying ability, a simple structure and a convenient adjustment.

Description

The gate-type reaction frame that is used for structural experiment

Technical field:

The utility model relates to experimental provision, a kind of gate-type reaction frame that is used for structural experiment of more specifically saying so.

Background technology:

In field of civil engineering, the important structure part need be done the carrying experiment.During experiment, actuator need be installed on the special-purpose reaction frame and could load structural member.

The gate-type reaction frame is to be column with H shaped steel, cross-over connection crossbeam between two heel posts.Present employed gate-type reaction frame version such as Fig. 4, shown in Figure 5, its central post 1 is a H shaped steel, being connected across between two heel posts 1 is crossbeam 2, each other with bolted on connection, but, in this existing version, the two ends of crossbeam 2 are to be bound up on the H shaped steel web of column 1, and this makes the span of gate-type reaction frame not regulate; Simultaneously, the surface of contact of bolted on connection is less, and load-bearing capacity is less.

The utility model content:

The utility model is for avoiding above-mentioned existing in prior technology weak point, and a kind of simple in structure, span is adjustable, load-bearing capacity is strong gate-type reaction frame that is used for structural experiment is provided.

The technical scheme that the utility model technical solution problem is adopted is:

The utility model constitutes a shape frame by two heel posts and the crossbeam that is connected across between two heel posts, and column adopts H shaped steel; It is characterized in that:

Crossbeam is installed on the flange plate of column H shaped steel by bolt;

On the flange plate of column, the column bolt hole that many groups are used to adjust the different setting height(from bottom)s of crossbeam longitudinally is set, on crossbeam, the locational many group transom bolts of different spans holes are set.

Design feature of the present utility model also is:

Column bolt hole on each height and position and the locational transom bolt of each span hole are biserial.

By different crossbeam span correspondences the ground T-shape groove that many rows are used to install column is set, each ground T-shape groove is parallel to each other.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, version of the present utility model makes the gate-type reaction frame can regulate on height and span.

2, the utility model is fixedly mounted on column H shaped steel flange plate with crossbeam, and the installation site surface of contact is big, and load-bearing capacity is strong.3, the utility model is simple in structure, and is easy to adjust.

Number in the figure: anchor nut on 1 column, 2 crossbeams, 3 column bolts hole, 4 transom bolt holes, 5 ground T-shape grooves, 6 grounds, the 7 lower margin screw rods, 8,9 times anchor nuts, 10 train wheel bridges, 11 lower plates, 12 screw rods, 13 actuator, 14 bearings, 15 tested members.

Below pass through embodiment, and in conjunction with the accompanying drawings the utility model is further described.

Embodiment:

Referring to Fig. 1, Fig. 2 and Fig. 3, present embodiment constitutes a shape frame by two heel posts 1 and the crossbeam 2 that is connected across between two heel posts 1, and column 1 adopts H shaped steel;

Shown in the figure, in the present embodiment, crossbeam 2 is installed on the flange plate of column H shaped steel by bolt; On the flange plate of column 1, the column bolt hole 3 that many groups are used to adjust the different setting height(from bottom)s of crossbeam 2 longitudinally is set, on crossbeam 2, the locational many group transom bolts of different spans hole 4 is set, by different crossbeam span correspondences the ground T-shape groove 5 that many rows are used to install column 1 is set, each ground T-shape groove 5 is parallel to each other.

In order to strengthen load-bearing capacity, column bolt hole 3 on each height and position and the locational transom bolt of each span hole 4 all are set to biserial.

In concrete the enforcement, on the ground 6 of workplace, establish and be parallel to each other and equally spaced each ground T-shape groove 5, column 1 by lower margin screw rod 7, go up anchor nut 8, anchor nut 9 and ground T-shape groove 5 are fixed in the ground 6 down; Crossbeam 2 has two, is fixedly mounted on respectively on the flange plate of H shaped steel both sides of two root posts 1.

Routine equidistantly is provided with three road ground T-shape grooves 5, and the transom bolt hole 4 that connects with column 1 on the crossbeam 2 is along having three groups on the span direction of crossbeam 2, and every group of spacing equates with spacing between the adjacent two ground T-shape grooves; When two root posts 1 are installed in two adjacent ground T-shape grooves respectively, select that two adjacent groups transom bolt hole connects crossbeam mutually with column on the crossbeam for use, the gate-type reaction frame span of composition is one times of T type separation; When two root posts are installed at interval in two ground T-shape grooves of one respectively, select for use two groups of transom bolt holes that are positioned at two ends on the crossbeam that crossbeam is connect mutually with column, the gate-type reaction frame span of composition is a twice T type separation;

In addition, as shown in Figure 1, be provided with routinely, train wheel bridge 10 and lower plate 11 are fixedly mounted on the crossbeam 2 by screw rod 12 and supporting nut; Actuator 13 withstands on the lower plate 11 being placed on tested member 15 application of forces on the bearing 14.
