Description

A vertical reinforcement device for non-support points of Bailey beam brackets

technical field

The utility model belongs to the field of auxiliary equipment for building construction sites, in particular to a vertical reinforcement device for non-support points of Bailey beam brackets.

Background technique

In recent years, infrastructure has developed rapidly, and Bailey beams are widely used in the construction of long-span houses and bridge supports. However, in some terrain restrictions or in the design of special structural supports, the supporting steel pipes and other stressed members inevitably act on the non-supporting points of the Bailey sheet. In order to ensure the stress safety of the structure, the construction party often needs to vertically reinforce the non-support points of the Bailey sheet. The usual practice is to cut a channel steel of appropriate length and stuff it between the upper and lower chords of the Bailey sheet, so that the upper and lower chords can be effectively supported. However, it is difficult to control the accuracy of channel steel cutting and filling in this way, and it is not guaranteed whether the upper and lower joints are tight to the Bailey sheet, and the reinforcement measures have potential safety hazards. At the same time, on-site cutting and filling construction are inconvenient.

Contents of the invention

The utility model provides a vertical reinforcement device for the non-support point of the Bailey beam support in order to solve the problem of lack of a special device when the non-support point of the Bailey beam support needs to be vertically reinforced.

The utility model is realized through the following technical scheme: a vertical reinforcement device for the non-support point of the Bailey beam bracket, including an upper support, a top tightening screw and a lower support connected as a whole along the same vertical line, the upper support and the lower support They are tightly connected with the upper chord and the lower chord of the thunder beam support respectively, the upper support includes an upper support rod, the bottom of the upper support rod is provided with a second connecting plate, the lower support includes a lower support rod, and the top of the lower support rod is provided with a first The connection plate, the first connection plate and the second connection plate are composed of two horizontal plates arranged at intervals, the middle part of the first connection plate is provided with a circular through hole, and the middle part of the second connection plate is provided with a threaded hole, and the screw is tightened Including the lower smooth round rod and the upper threaded rod, a nut A is fixed at the junction of the smooth round rod and the threaded rod, a nut B is fixed at the bottom of the smooth round rod, and the smooth round rod is set on the circle in the middle of the first connecting plate The nuts A and B are respectively arranged in the two ends of the first connecting plate in the through-hole, and the threaded rods are threadedly connected with the threaded holes of the second connecting plate. Between two adjacent lower supports or between two adjacent upper supports Connection boxes fixed by connection bolts are respectively arranged.

The distance between the nut A and the nut B is 5-10 mm larger than the vertical dimension of the first connecting plate.

The upper support rod and the lower support rod are channel steels of the same type.

The connection box is a rectangular box structure welded by steel plates, and the width of the connection box is the same as the web size of the channel steel selected for the upper support rod and the lower support rod.

When the utility model is in use, the light round rod that tightens the screw rod rotates freely in the first connecting plate, and the threaded rod that tightens the screw rod moves vertically relative to the second connecting plate, thereby realizing upper support, lower support and shell The top and bottom chords of the thunder beam are tight.

The beneficial effect that the utility model has compared with prior art is:

The utility model has a simple structure and a reasonable design. The support member is closely attached to the top of the Bailey sheet by using the jacking bolts, which effectively solves the problem of strengthening the Bailey beam bracket at the non-support point, reduces construction safety risks, reduces labor intensity, and Help to improve construction efficiency.
