Abstract
The utility model relates to a reverse bracket structure of foundation ditch steel shotcrete belongs to construction technical field. A reverse bracket structure of a foundation pit steel support comprises a support beam, a reverse bracket and a stand column; the side surface of the support beam is fixedly connected with the upright post; the bottom surface of the anti-bracket is placed on the support beam and is connected with the support beam through bolts, and the side surface of the anti-bracket is welded with the upright post. The bracket is placed on the bracket beam and connected with the bracket beam through the bolt, so that the problem that the bracket is buried in the floor slab due to insufficient net height of the support and the floor slab to influence the construction of the main structure can be avoided.
Description
Technical Field
The utility model relates to a reverse bracket structure of foundation ditch steel shotcrete belongs to construction technical field.
Background
In order to ensure the safety of the construction of the underground structure and the surrounding environment of the foundation pit, the side wall of the foundation pit and the surrounding environment need to be supported, reinforced and protected. In deep foundation pit engineering of high-rise buildings or subway construction, most of the deep foundation pit engineering is excavated in cities, various structures such as traffic main roads, built buildings or pipelines and the like usually exist around the foundation pit, and in order to ensure the safety of the surrounding environment of the foundation pit, save the construction period and the cost, the assembled prestressed beam-string steel support system is widely applied.
In the prior art, a common foundation pit steel support can be detached only after the basement floor is poured, the distance between a bearing surface and the floor is close, and a support beam and a bracket are arranged under the foundation pit steel support, so that the bracket often conflicts with the floor, an opening needs to be reserved for the bracket when the floor needs to be poured on site, or the bracket and the floor are directly poured together, and the construction difficulty is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an on anti-bracket structure puts the bracket on support upper portion and leg joint, avoids because support and the not enough bracket that leads to of floor clear height bury inside the floor, influence the major structure construction.
The utility model adopts the following technical proposal:
a reverse bracket structure of a foundation pit steel support comprises a support beam 3, a reverse bracket 1 and a stand column 2; the side surface of the support beam is fixedly connected with the upright post 2; the bottom surface of the anti-bracket 1 is placed on the support beam 3 and is connected with the support beam 3 through bolts, and the side surface of the anti-bracket 1 is welded with the upright post 1.
Preferably, the support beam 3 comprises a horizontal main body part and an upright support part, the main body part is welded and fixed with the upright post 2, and the support part is fixed below the main body part.
Furthermore, still include connecting plate 4, the horizontal one end of connecting plate 4 with the supporting part is fixed, and horizontal other end is fixed with stand 2.
Preferably, the supporting part is provided with an upright stiffening plate, and the connecting plate 4 is welded and fixed with the stiffening plate.
Preferably, the angle between the counter bracket 1 and the upright post 2 is 30-60 degrees.
Further, the floor elevation is lower than the support beam 3 and the connecting plate 4.
The beneficial effects of the utility model reside in that: place anti-bracket on the support roof beam, be connected through bolt and support roof beam, can avoid because support and the not enough bracket that leads to of floor net height bury in the floor inside, influence the problem of major structure construction.
Drawings
Figure 1 is the utility model discloses anti bracket structure's of foundation ditch steel shotcrete front view.
Fig. 2 is a sectional view a-a in fig. 1.
In the figure, 1 is a reverse bracket, 2 is a vertical column, 3 is a support beam, and 4 is a connecting plate.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-2, a reverse bracket structure of a foundation pit steel support comprises a support beam 3, a reverse bracket 1 and a vertical column 2; the side surface of the support beam is fixedly connected with the upright post 2; the bottom surface of the reverse bracket 1 is placed on the support beam 3 and is connected with the support beam 3 through bolts, and the side surface of the reverse bracket 1 is welded with the upright post 2.
In this embodiment, referring to fig. 1-2, the support beam 3 includes a horizontal main body part welded to the upright post 2 and an upright support part fixed below the main body part.
In this embodiment, referring to fig. 1-2, the device further comprises a connecting plate 4, wherein one transverse end of the connecting plate 4 is fixed to the supporting part, and the other transverse end of the connecting plate 4 is fixed to the upright post 2.
In this embodiment, see fig. 2, the support has upright stiffening plates to which the connection plates 4 are welded.
In this embodiment, the counter bracket 1 is at an angle of 30-60 degrees, preferably 45 degrees, to the upright 2, see fig. 1.
In this embodiment, see fig. 1, the floor level is lower than the bracket beams 3 and the connection plates 4.
The utility model discloses to prevent that the bracket is placed on the support beam, be connected with the support beam through the bolt, can avoid because support and the not enough bracket that leads to of floor net height bury in the floor inside, influence the problem of major structure construction.
The above are preferred embodiments of the present invention, and those skilled in the art can make various changes or improvements on the above embodiments without departing from the general concept of the present invention, and these changes or improvements should fall within the scope of the present invention.
