Description
Technical Field
The utility model relates to the field of building electromechanical installation engineering, which is mainly used for connecting a direct-buried bridge frame with a bridge frame.
Background
At present, bridge holes are reserved in the conventional method of an electric well in the electric pre-buried stage, the method of replacing the original reserved holes with a direct-buried bridge is proposed at present, but the method has the problem that the connection is not easy after concrete pouring is completed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an accessory which is convenient to install, can be used for embedding various bridges and is beneficial to connection between the embedded bridges.
The utility model solves the technical problems through the following technical scheme:
the utility model provides a bridge transition joint piece for one-time pre-embedding, which is characterized by comprising two connecting plates, wherein each connecting plate is provided with a long strip-shaped waist-shaped hole and a row of small waist-shaped holes, the two connecting plates are respectively fixed on the opposite inner walls of an upper-layer bridge through first fastening bolts penetrating the corresponding long strip-shaped waist-shaped holes, the long strip-shaped waist-shaped holes of each connecting plate can adjustably and vertically move along the corresponding first fastening bolts, so that the first fastening bolts are positioned at the tops of the corresponding long strip-shaped waist-shaped holes, the bottoms of the connecting plates slide downwards to be pulled out of the bottom of the upper-layer bridge, and the small waist-shaped holes of the pull-out parts of the connecting plates are fixed on the adjacent lower-layer bridge through second fastening bolts penetrating the connecting plates.
Preferably, the number of the small waist-shaped holes in one row is four, the four small waist-shaped holes are vertically arranged, and the small waist-shaped holes are arranged in parallel with the strip-shaped waist-shaped holes.
Preferably, the thickness of the connecting plate is 1 mm.
Preferably, the upper layer bridge frame and the lower layer bridge frame both have the size of 200mm in length and 100mm in width, and the size of the connecting plate has the size of 180mm in length and 60mm in width.
On the basis of the common knowledge in the field, the above preferred conditions can be combined randomly to obtain the preferred embodiments of the utility model.
The positive progress effects of the utility model are as follows:
the transition joint piece is simple in form and can effectively play a role in connecting the bridge. After the concrete is cast and the template is removed, the transition section slides downwards and is pulled out for connection and fixation before the bridge frame is installed. The bridge pre-embedding construction method is suitable for bridge pre-embedding construction of a floor slab, and the phenomenon that the bridge cannot be connected after the bridge is pre-embedded in a concrete structure can be effectively solved.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1-3, the present embodiment provides a bridge transition piece for one-off pre-embedding, which comprises two connecting plates 1, wherein each connecting plate 1 is provided with a strip-shaped waist-shaped hole 2 and four small waist-shaped holes 3 which are vertically arranged, the small waist-shaped holes 3 are arranged in parallel with the strip waist-shaped holes 2, two connecting plates 1 are respectively fixed on the opposite inner walls of the upper layer bridge frame 5 through first fastening bolts 4 penetrating the corresponding strip waist-shaped holes 2, the strip waist-shaped hole 2 of each connecting plate 1 can adjustably and vertically move along the corresponding first fastening bolt 4, so that the first fastening bolt 4 is positioned at the top of the corresponding elongated kidney-shaped hole 2, the bottom of the connecting plate 1 slides downwards to be pulled out of the bottom of the upper layer bridge frame 5, the small kidney-shaped hole 3 of the pull-out part of the connecting plate 1 is fixed on the adjacent lower layer bridge frame 7 through a second fastening bolt 6.
In the stage of field structure construction, the size of a corresponding bridge transition joint piece is determined according to the size of a bridge, the sizes of the upper-layer bridge 5 and the lower-layer bridge 7 are both 200mm in length and 100mm in width, the size of the connecting plate 1 is 180mm in length and 60mm in width, and the thickness of the connecting plate 1 is 1 mm.
The matched connecting plate is manufactured according to the specification and the material of the bridge, the connecting plate is used for fixing and connecting the internal connection between the bridge and the bridge, the connecting plate is connected with the bridge through bolts for reserving 1mm, the connecting plate can slide after the template is detached conveniently, and the phenomenon that the bridge cannot be connected after the concrete structure is embedded can be effectively solved.
The construction mode of the transition joint piece is similar to that of a reserved sleeve, and the difference is that the transition joint piece needs to be prevented from being extruded to deform in the concrete solidification process, and fillers such as foam and the like can be filled in the transition joint piece, so that the integral stress performance of the transition joint piece is enhanced.
After the template is removed after the structure construction is finished, the connecting plate in the transition piece is drawn out to serve as a transition bridge for connecting the upper layer bridge frame and the lower layer bridge frame.
While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and that the scope of the utility model is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the utility model, and these changes and modifications are within the scope of the utility model.
