Description

TECHNICAL FIELD

The steel pipe bundle concrete structure not only has the characteristics of good stability of steel components, light structure dead weight and good seismic performance, but also can be produced by industrial production line, has high industrialization degree and fast installation and construction speed. In the steel pipe bundle concrete structure, the hollow lattice type steel pipe bundle is both a cast-in-place concrete form and a load-bearing structure, and is a new building form more suitable for assembly type structure. The hollow lattice type steel pipe bundle is integrated and processed, then assembled at the construction site, and finally connected together by cast-in-place concrete to form an assembly type structure, which is equivalent to a cast-in-place structure, and has fast construction, so that the building form has good application prospect.

[0003] The existing assembly type building has insufficient design refinement, cooperation and completion degree, and more bolts are used for fixing at the connecting position, so that the in-plane surface of the connecting position is not flat, and there are protrusions or other excess components, which are not conducive to the design of structure, thermal insulation and decoration integration. In addition, the vertical segmentation position of the assembly type structure is usually at the floor, and the next layer is installed after the floor concrete cast-in-place curing, although the construction is convenient, but the weak connection position is located at the position with large stress, resulting in poor connection performance between the vertical components, and the overall performance of the assembly type structure and the safety performance of the building depend on the firmness of the connection. If the vertical segmentation position of the assembly type structure is arranged at a position other than the floor, the interlayer position has small stress, not only enhances the reliability of the floor support plate connection, but also simplifies the connection structure, and also enhances the safety performance of the building.

[0004] Therefore, the application provides a steel pipe bundle buckle type connecting structure and wall limb assembly construction process, which is suitable for the assembly type steel pipe bundle concrete structure segmented at the interlayer, the steel pipe bundles are connected through buckles, connecting cover plates or buckling plates, has convenient and reliable connection, flat surface at the connecting position of the steel pipe bundle, and is conducive to the internal concrete pouring into one body.

[0026] 2、The design of the connecting cover plate considers the convenience of field installation according to the different height and span of the steel pipe bundle, and can be divided into several identical cover plate units along the axial direction. The connecting cover plates are staggered in sawtooth shape, which strengthens the connection between the connecting cover plate and the steel pipe bundle panel; the connecting cover plate is welded with vertical ribs between the second layer of steel plate fasteners in the same column, which can make up for the steel loss after cutting the vertical steel plate at the left and right ends of the steel pipe bundle; the connecting cover plate and the steel pipe bundle panel are in the same vertical plane, and after installing the temporary lateral support, the cast-in-place concrete is poured, and the bolts arranged inside the connecting cover plate make the structure and the cast-in-place concrete become one, which can ensure the safety and integrity of the connection between the steel pipe bundles, and is beneficial to speed up the construction progress and improve the construction quality.

[0027] 3、The length of the single steel plate fastener and the double steel plate fastener matches the edge width of the vertical steel plate opening of the steel pipe bundle, and after being buckled into the fastener, the edge position of the vertical steel plate opening is completely connected together by the fastener, ensuring the stability of the left, right and upper and lower connections, and preventing the fastener from falling off during assembly. After pouring the concrete, the fastener, the connecting cover plate and the steel pipe bundle are connected as a whole. The use of steel plate fasteners and connecting cover plates to connect the steel pipe bundle improves the steel ratio at the connection, ensures the strength and stiffness of the connection, and integrates the shear wall with the steel pipe bundle after pouring the concrete on site, which is beneficial to ensure the integrity and safety of the structure.

An L-shaped rib is welded on the floor support plate, and the height of the L-shaped rib matches the thickness of the assembled floor. The floor support plate is connected to the vertical steel plate at the slot of the steel pipe bundle panel using a wedge-shaped steel plate, and the connection between the floor support plate and the steel pipe bundle is strengthened. The L-shaped rib on the floor support plate is extended and welded with the vertical steel plate of the steel pipe bundle at the slot of the steel pipe bundle, and there is no gap between the two adjacent floor support plates during the horizontal assembly of the steel pipe bundle. During the pouring of the concrete on site, the floor reinforcement can be inserted into the L-shaped rib to realize the anchoring function of the floor reinforcement. The steel pipe bundle, floor support plate, L-shaped rib and assembled floor form a whole, ensuring the safety and reliability of the connection between the floor and the vertical steel pipe bundle concrete member.

[0029] 5. The connecting mode of horizontal or vertical buckling plate is adopted to solve the connection of steel pipe bundle, the horizontal buckling plate is staggered up and down on the left and right steel pipe bundles to facilitate the site pouring of concrete, the welding end of the horizontal buckling plate is alternately arranged in the left and right steel pipe bundles to ensure the integrity of the connection after the steel bar is inserted into the hole of the horizontal buckling plate, the vertical steel plate of the steel pipe bundle, and the vertical buckling plate is inserted into the hole on one side of the steel bar in the upper and lower steel pipe bundles, and the hole of the vertical steel plate of the steel pipe bundle should ensure that the horizontal steel bar can be inserted, or the non-welding side of the vertical buckling plate is welded with a bolt, to ensure the integrity of the connection of the upper and lower steel pipe bundles; the intersecting part of the steel bars connected by the horizontal buckling plate or the vertical buckling plate should be overlapped, so as to ensure the safety of the whole structure of the steel pipe bundle concrete.

[0030] 6. When the steel pipe bundle is longitudinally and transversely connected, the steel pipe bundle can be prefabricated into L-shaped, cross-shaped, T-shaped, Z-shaped or C-shaped shapes, and the production and connection refer to the L-shaped steel pipe bundle; when the site is spliced, first, the accurate fixing of the hollow lattice type steel pipe bundle yin and yang corner parts is ensured, then the installation is gradually installed from one end to the other end, which is convenient for the connection with the adjacent wall body, so that the construction is more convenient and fast, so that the steel pipe bundle buckling connection structure of the present application solves the steel connection problem of the prefabricated building construction site, and the connection is reliable and convenient, then the commercial concrete is uniformly layered and poured, which is equivalent to the cast-in-place structure, so that the level of building industrialization is improved.
