The utility model relates to a template device belongs to the construction engineering technical field, concretely is a parapet wall internal corner integrated forming template device, including floor and parapet wall, the parapet wall fixed mounting is at one side of floor, still includes, stainless steel frame body, the stainless steel frame body sets up between floor and parapet wall, the inside fixed mounting of stainless steel frame body has the reinforcing rib, the utility model reached the effect that the stability and waterproofness of waterproof base layer have been improved significantly, solved the mode of the existing adoption mortar to do arc, because mortar and base layer bond not firm etc. cause arc loose cracking, rainwater is easy to penetrate along the crack, and then seriously influence waterproof effect, bring the problem of leakage hidden danger to building.

The invention relates to the field of foundation pit excavation, and discloses an embedded anchorage device structure for reducing the excavation volume of a foundation pit, which comprises a steel support, an operation cavity is formed in the steel support, a drilling hole is formed in one side, close to the center of a pile body, of the steel support, a drilling tool penetrates through the drilling hole, and a pressure-bearing part and an anchorage device are sequentially arranged on one side, close to the operation cavity, of the drilling hole; the outer diameter of the pressure-bearing piece is larger than that of the drilling opening, a first containing hole is formed in the pressure-bearing piece, the inner diameter of the first containing hole is smaller than that of the anchorage device, the first containing hole is used for allowing the anchor cable to penetrate through, and the anchorage device is matched with the anchor cable in size. A fertilizer groove filling layer is omitted, foundation pit excavation is reduced, the environment is protected, and green, energy-saving and low-carbon effects are achieved.

The invention relates to the field of foundation pit excavation, and discloses a construction method of an embedded anchorage device structure for reducing the excavation volume of a foundation pit, which comprises the following steps: step 1, preparing an embedded part and a reinforcement cage, and mounting the embedded part on a main reinforcement of the reinforcement cage; an operation cavity is formed in the embedded part, a drilling opening is formed in the side, close to the center of the reinforcement cage, of the embedded part, and a drilling tool penetrates through the drilling opening; secondly, a reinforcement cage is placed in the pile hole, and pile body concrete is poured; thirdly, a foundation pit is excavated, an embedded part is found, an anchor hole is drilled in the position of a drilling opening, an anchor cable is placed in the anchor hole, and grouting is conducted on the anchor hole; fourthly, a pressure-bearing piece and an anchorage device are sequentially placed on the drilling opening, the outer diameter of the pressure-bearing piece is larger than that of the drilling opening, a first containing hole is formed in the pressure-bearing piece, the inner diameter of the first containing hole is smaller than that of the anchorage device, the steel cable sequentially penetrates through the drilling opening, the first containing hole and the anchorage device, the anchor cable is tensioned, and the anchor is sealed. A fertilizer groove filling layer is omitted, foundation pit excavation is reduced, the environment is protected, and green, energy-saving and low-carbon effects are achieved.
