The invention belongs to the technical field of gel spinning, and discloses an auxiliary tooling for dispersing gel fibers into a net, including a device shell, the top of the device shell is fixedly equipped with a lowering barrel, and the device shell is divided into an upper oval part and the lower rectangular part, a side door is fixedly installed on the left side of the lower rectangular part of the device housing, and an upper partition and a lower partition are fixedly installed in the inner chambers of the upper oval part and the lower rectangular part of the lower bucket. The present invention heats the airflow through the heating box. After entering the outer enclosure from the air inlet channel, the airflow will flow along the connection tangent between the outer enclosure and the air inlet channel, and finally form a ring around the inside of the outer enclosure. Downward vortex, the annular cyclone airflow will fill the inner cavity of the entire outer enclosure, and its flow direction is opposite to the rotation direction of the spinner, which improves the heat exchange rate and air-drying speed of the gel fiber filaments, and prevents the fiber embryos from The body produces fiber adhesion and improves the quality of spinning.

The invention discloses a beam-string-structured double-curved arched roof board beam structure. A concrete double-curved arch plate is used as an upper chord of a compression area of an arched beam string structure, a broken-line-shaped steel wire dragline of the arched beam string structure is used as a lower chord of the compression area of the roof boarding double-curved arch plate, the arched beam string structure and the roof board double-curved arch plate are combined for usage, have complementary advantages and work together in a cooperative mode. The arched beam string structure is hoisted to a roof of a factory building with a single story, pressure type steal plate micro-bending arch waves are paved between arch ribs, the concrete arch plate is poured on site, and a construction technology of breaking up a whole into parts fully embodies the advantages of industrialized prefabrication assembly. The novel roof board beam structure has the advantages of high bearing capacity, high span capacity, good structure stability, unification of the plate and the beam structure, good waterproof property, fast construction, low cost and the like, and is used for super-large span factory building roof board beam structures of 40-90 meters.

The invention provides a rigid-connection connector of a sandwich shear wall structure. The rigid-connection connector comprises an anchor socket, an inner anchor bar, an outer anchor bar and anchor body materials, wherein the anchor socket penetrates through and is fixedly arranged on a sandwich layer of a sandwich shear wall, the inner anchor bar and the outer anchor bar are fastened on the anchor socket, the anchor body materials are arranged on the anchor socket, and tensioning action on welding meshes which are preset in cavities of an inner wall and an outer wall can be respectively formed by the inner anchor bar and the outer anchor bar. The invention also provides the application of the rigid-connection connector in respect of inner wall or outer wall construction of the sandwich shear wall structure. According to the rigid-connection connector provided by the invention, the structural performance is reliable, the reliable force transmission of the inner wall and the outer wall of the sandwich shear wall is ensured, the whole structure is excellent, industrial production can be carried out, and the cost performance is high.

The invention discloses a joint of a cable support pentagonal and hexagonal grid single-layer reticulated shell and an installation and construction method for the single-layer reticulated shell. The joint comprises a bottom plate, a cover plate, a middle circular tube and an internal Y-shaped stiffening rib. The internal Y-shaped stiffening rib is adopted when necessary, and the cover plate is formed by cutting a circular plate and welded to the middle circular tube. Circular holes are formed in the corresponding positions where the middle circular tube is connected with inhaul cable so that inhaul cable ends with threads can penetrate into the joint from outside to inside, the inhaul cables are screwed up through nuts inside the joint, and prestressing force is applied to the inhaul cables. The installation and construction method for the single-layer reticulated shell constructed on the basis of the joint is carried out according to the following steps that components, rod pieces and the inhaul cables of a joint body are machined and manufactured in a factory firstly, then the joint body and the machined reticulated shell rod pieces are constructed and installed, the inhaul cables are installed, the nuts are tightened up, prestressing force is applied to the inhaul cables, and finally the cover plate and the middle circular tube are welded together. The joint of the form has the advantages of being reasonable in stress, simple in structure, convenient to machine, construct and install and the like.

The invention discloses a method and structure for reinforcing original plant concrete corbels. When the concrete corbel of an original plant concrete column is reinforced, a steel corbel is firstly manufactured below the concrete corbel on the concrete column, and then, a short concrete column for supporting the concrete corbel is poured on the steel corbel. In the invention, by additionally arranging one steel corbel on the basis of the original concrete column and pouring the short column for supporting the concrete corbel on the steel corbel, the bearing capacity of the original concrete corbel can be effectively reinforced on the basis of not occupying plant ground and not reforming a foundation, and thus, the structural safety is guaranteed. Therefore, compared with the prior art, the method and structure disclosed by the invention not only have the advantages of no plant ground occupation, easiness for construction and low manufacturing cost, but also have the advantages of simple structure, higher structural strength, short construction period and reliable structural properties.

The invention discloses a roof with an approximately quadrate plane and a super large space pre-stressed steel grid structure and a manufacturing method thereof. When the roof with the approximately quadrate plane of which the ratio of long side L1 to short side L2 is more than or equal to 1 and less than 1.5, L1 is more than or equal to 120 meters and less than or equal to 165 meters and L2 is more than or equal to 90 meters and less than or equal to 150 meters is manufactured, a fusiform space tube truss consisting of a top boom, a lower boom and a diagonal web member is orthogonally connected with another fusiform space tube truss at the same space height position so as to form a grid structure consisting of the fusiform space tube truss; four fusiform space tube trusses constituting the grid structure are manufactured into support stay bar type cable-stayed self-balancing orthogonal space tube trusses; and the central structural heights of all fusiform space tube trusses and the four fusiform support stay bar type cable-stayed self-balancing orthogonal space tube trusses are controlled to be between L2 / 18 and L2 / 16. The roof has the advantages of small occupied space height, small using amount of steel, reliable structural performance, easy manufacturing and construction, low cost and the like.
