As shown in fig. 4, the thickness of the block in this embodiment is smaller than the height of the U-shaped groove, based on which, when building the cornice 2, a layer of mortar needs to be coated on the bottom of the U-shaped groove, and then the block is clamped in the through groove on the upper part of the mortar to form the cornice 2. Of course, in the concrete implementation, the building blocks which are suitable for the upper and lower heights of the U-shaped grooves can be selected to build the cornices.
In S7, the U-shaped groove is sealed by the following method: as shown in fig. 5, a prefabricated drip edge is clamped in the U-shaped groove; the prefabricated dripping eave is fixed on the structure through mortar adhesion, and the adopted mortar and the concrete poured by the structure are the same in label. Before the building blocks are inserted or before the prefabricated dripping eave is clamped, a layer of steel wire mesh is fully paved in the U-shaped groove. Specifically, the prefabricated dripping eave is made of plastic or aluminum alloy and consists of a connecting plate and an epitaxial plate, and the epitaxial plate is oppositely and obliquely arranged to form a water guide plate. A plurality of through holes for bonding mortar are arranged on the connecting plate at intervals along the length direction of the dripping eave.
The embedded channel steel 1 is fixed by the following method: the embedded channel steel 1 comprises a horizontal plate 11 arranged up and down and a vertical plate 12 arranged between the two horizontal plates 11, and a plurality of opposite-pull perforations 13 are arranged at intervals in the length direction of the vertical plate; the embedded channel steel 1 sequentially passes through the vertical plates, the structure steel bars and the templates on the opposite sides of the embedded channel steel through a plurality of wire drawing rods and then is matched with the nuts to be fixed on the templates.
In order to avoid slurry leakage during pouring, a fixing plate 14 arranged towards the upper side and the lower side of the opening is arranged on one side of the opening of the embedded channel steel and the end parts of the two horizontal plates 11, and the fixing plate 14 is fixedly connected with the end parts of the horizontal plates or is formed by directly bending the horizontal plates vertically.
After the outer edge of the waterproof coiled material is clamped into the U-shaped groove, the end part of the opposite-pulling screw rod which is arranged in the U-shaped groove in a penetrating manner is fixed in the U-shaped groove through adhesive.
The vertical distance between the embedded channel steel and the roof is more than 30 cm.
When the template is erected, the bottom of the template is tightly attached to the roof structure, foam strips are sealed at the junction of the template and the roof, and when the concrete implementation is carried out, foam glue is also adhered at the junction of the side mould and the embedded channel steel 1 for sealing, so that slurry leakage is avoided. Before the construction template is installed, a positioning steel bar is required to be implanted along the installation position of the template and the length direction of the template; the supported templates comprise side dies on two sides and end dies fixed between the two side dies, a plurality of reinforced wood beams are arranged at intervals on the outer sides of the side dies, the side dies on two sides are fixed through opposite-pulling screws arranged at intervals in a plurality of rows, when the opposite-pulling screws are fixed, the lowest row of opposite-pulling screws are screwed first, then the opposite-pulling screws on the top are screwed, and finally the middle opposite-pulling screws are screwed.

Before concrete pouring, cement mortar with the same proportion as the concrete is adopted to carry out grouting treatment on the horizontal construction joint, and grouting is mainly used for preventing root rot of a wall body, and the thickness is controlled to be 50-100 mm.
After concrete pouring, the concrete needs to be vibrated: the insertion point distance of the vibrating rod is 1.5 times of the action radius of the vibrating rod, and is generally 400 mm. The arrangement of the insertion points should be uniform. The concrete is vibrated by quick and slow insertion and extraction until the bubbles in the concrete are exhausted. When pouring and vibrating concrete on the slope, the concrete should not be poured downwards from the upper part of the slope, but pouring the concrete upwards from the bottom of the slope.
The boundary of the two vibrating hands should be vibrated beyond 50 cm. After the lower layer concrete is vibrated, the vibrating rod should go deep into the concrete to be poured for 5cm vibration when the upper layer concrete is vibrated. The vibrating rod cannot excessively vibrate at the same position due to overlong vibrating time, so that stones are prevented from sinking, cement paste floats upwards and a template expands, and the strength and appearance quality of concrete are affected.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the technical solution, and although the applicant has described the present invention in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents of the technical solution of the present invention can be made without departing from the spirit and scope of the technical solution, and all such modifications and equivalents are intended to be encompassed in the scope of the claims of the present invention.
