Description

Prefabricated ecological crown beam Technical Field The utility model belongs to the technical field of civil engineering, and particularly relates to a prefabricated ecological crown beam. Background The crown beam is a reinforced concrete continuous beam structure arranged at the top of a foundation pit supporting structure in the building engineering, is mainly used for enhancing the overall stability and deformation resistance of a supporting system, is of an integral structure, is complex in die structure, complex in production operation procedures, low in production efficiency and high in die manufacturing cost, and is very inconvenient for later construction due to the fact that the whole concrete of the crown beam is large in using amount and heavy in unit weight. Disclosure of Invention In order to solve the technical problems, the utility model provides a prefabricated ecological crown beam, which comprises a front vertical plate, wherein a rear vertical plate is arranged at the rear side of the front vertical plate, the front vertical plate and the rear vertical plate are arranged in a front-rear mirror image mode, a plurality of first beam grooves uniformly distributed in the left-right direction are formed in the rear side surface of the front vertical plate, a second beam groove which is arranged in a front-rear mirror image mode with the first beam groove is also formed in the rear vertical plate, a beam is arranged between the front vertical plate and the rear vertical plate, and the front end and the rear end of the beam are respectively inserted into the first beam groove and the second beam groove. As a preferable technical scheme of the utility model, the cross beam is provided with bolt holes in the front-rear direction, the number of the bolt holes is at least two, and the bolt holes are through holes. As a preferable technical scheme of the utility model, counter sunk holes with the same number as the bolt holes are arranged on the front vertical plate and the rear vertical plate, the bolt holes are mutually aligned with the counter sunk holes, and one counter sunk side of the counter sunk holes is positioned on one surface of the front vertical plate and the rear vertical plate which are mutually far away from each other. As a preferable technical scheme of the utility model, the bolt hole and the countersunk hole are internally inserted with a connecting bolt, the connecting bolt penetrates from the countersunk hole at the front side, penetrates out from the countersunk hole at the rear side after penetrating through the bolt hole, and one threaded end penetrated out by the connecting bolt is connected with a fastening nut, so that the front vertical plate, the cross beam and the rear vertical plate are connected into a whole. As a preferable technical scheme of the utility model, a plurality of drain holes are formed on the plate surface of the rear vertical plate, and the drain holes are uniformly distributed in the left-right direction. As a preferable technical scheme of the utility model, the left and right ends of the front vertical plate and the rear vertical plate are respectively provided with an alignment hole. Compared with the prior art, the utility model has the beneficial effects that: 1. The whole structure of the crown beam is divided into the single components of the plate and the beam, so that the die structure becomes very simple in production and the die manufacturing cost is very low. 2. The crown beam can be split into single components, so that the production process can be split into component monomers, the operation process becomes simpler, and the production efficiency becomes high. 3. The storage space of the single component is reduced, the storage quantity of the storage capacity with the same area is increased, and the site occupation cost is reduced. 4. The monomer component of the utility model has small volume and light weight, thus being very convenient for transportation, loading and unloading and on-site transportation. 5. When the utility model is installed in an assembled mode on site, only one piece of small equipment is needed to realize hoisting, the hoisting equipment can be used for construction on sites where large hoisting equipment cannot pass, and the application scene is wider. 6. The ecological function of the crown beam is also obvious, plants can grow normally in soil on the crown beam, and the phenomenon that the plants soak water and rot roots is effectively avoided. 7. The decorative patterns can be set as stone-like patterns, bark-like patterns, brick-like patterns and the like according to the requirements, so that the rigid impression of the traditional concrete surface is changed, and the decorative patterns have a beautifying function.
