A half-honeycomb floor includes a top plate, a rib structure defining a plurality of recessed areas, and a plurality of circular blind holes formed in each of the recessed areas. The rib structure sequentially defines a first rib, a second rib, a third rib, a fourth rib, a fifth rib, a sixth rib, and a seventh rib from an edge of the top plate toward a center. The implementation of the present application can avoid burrs or fragmentation of the half-honeycomb floor during secondary processing, speed up the secondary processing speed, and reduce the weight of the half-honeycomb floor.

This invention relates to the field of subsea concrete sphere battery technology, and discloses a prefabricated subsea concrete sphere battery and its construction method. The battery includes a concrete base, with a prefabricated concrete sphere assembly mounted on the upper end of the concrete base. A generator set is installed inside the concrete base, and the generator set is connected to the prefabricated concrete sphere assembly via a first pipeline. A water pump is installed on one side of the generator set. The prefabricated concrete sphere assembly includes a concrete sphere top cover and a first sidewall component connected to one side of the concrete sphere top cover. A concrete sphere bottom cover is provided on the opposite side of the prefabricated concrete sphere assembly. The concrete sphere top cover, the first sidewall component, the second sidewall component, and the concrete sphere bottom cover are all connected and fixed using Ω-shaped compression sealing steel strips. This invention solves the problems of manufacturing, transportation, installation, and long-term sealing of ultra-large concrete spheres.

The invention relates to the technical field of bridge engineering construction, aims to solve the problems that in the prior art, an embedded steel bar and a bearing platform formwork conflict in installation, the lap joint length of the steel bar is difficult to guarantee, and the steel bar and a sleeve are difficult to align, so that connection is not solid, and the construction efficiency is low, and provides a connecting structure of an assembly type bridge pier column and a bearing platform and a construction method. The structure comprises a prefabricated bearing platform, a pier column, three types of reinforcing steel bars, a high-strength threaded sleeve and pouring joint concrete, efficient and stable connection is achieved through the four steps of bending reinforcing steel bar presetting, assembly standardization, double fixing and concrete packaging, and construction is divided into four steps, and the structure is suitable for construction of various assembly type bridges. The method has the advantages that the embedded steel bars and the bearing platform formwork are installed in a matched mode, the lap joint length of the steel bars is convenient to guarantee, the steel bars and the sleeves are easy to align, and connection stability and high construction efficiency are guaranteed.

This utility model discloses an H-beam assembly fixture, relating to the field of H-beam production and processing. It includes a base, a stop seat, a sorting mechanism, and two sets of flange plate positioning mechanisms. A support seat for placing the web plate is fixedly installed on the top of the base. The stop seat is fixedly installed at one end of the base, with its side contacting the web plate. The two sets of flange plate positioning mechanisms are symmetrically arranged on both sides of the support seat. Each flange plate positioning mechanism includes a bearing part, a pushing component, and a second hydraulic rod. The bearing part is integrally connected from an L-shaped plate and a long vertical plate. This utility model, by suspending the flange plate into the storage cavity of the bearing part and controlling the extension of the second hydraulic rod, moves the clamping plate towards the flange plate, causing multiple pulleys to contact the flange plate, thereby clamping and positioning the flange plate between the pulleys and the L-shaped plate. This significantly improves the stability of the flange plate during assembly. Furthermore, the friction is small when the pulleys initially contact the flange plate, making it easier to align the flange plate.

The utility model discloses assembly type building grouting sleeve template alignment ware, including sleeve: the sleeve right side inserts and unites the grouting pipe, the sleeve left side welding has the threaded butt joint pipe of being linked with its intercommunication, threaded butt joint pipe is connected with steel template thread, the inner chamber of sleeve is provided with the plugging component, the plugging component includes the guide pin of welding in sleeve inner chamber front side and rear side all welding, the inner chamber slidingly connected of sleeve has the plug, the right side of sleeve is provided with the grouting hole of being matched with plug. The utility model discloses through the setting of threaded butt joint pipe, makes sleeve and steel template connect, then under the use of threaded sleeve cooperation, makes sleeve and grouting pipe complete butt joint, simultaneously under the use of plugging component cooperation, realizes automatic opening and plugging, finally through grouting pipe and external grouting machine to the grouting in steel template, can reach the purpose of alignment simple and quick and automatic opening plugging.
