Abstract
Description
Technical Field
[0001] The utility model belongs to the field of building reinforcement construction, and in particular relates to a connection structure for reinforcing section steel between structural beams. Background Art
[0002] In recent years, with the increasing number of renovation projects and the increasing maturity of renovation and reinforcement technology, traditional renovation and reinforcement methods have also been continuously updated in pursuit of construction convenience and efficiency. For roof ventilation shaft renovation, concrete beams are often used as upper wall supports. However, the concrete beam formwork, formwork laying, steel bar binding and pouring and curing are relatively cumbersome and the construction period is long. This is not conducive to construction under tight construction schedules, which invisibly increases labor costs and time costs. Summary of the Invention
[0003] To overcome the shortcomings of existing technologies, this utility model provides a connection structure for reinforcing steel sections between structural beams. Specifically, a steel section support is installed at the beam location, the steel beam is fixed for support, the masonry width is installed on the beam, the slab is chiseled out, a concrete slab is reserved, and masonry is built on the concrete slab. This technology replaces traditional cast-in-place beam supports and uses a steel structure combined with a reserved slab, significantly shortening the construction period.
[0004] The technical solution adopted by the present invention to solve this technical problem is: a connection structure for reinforcing steel sections between structural beams, including a structural beam, "H"-shaped steel, an anchoring structure, a connection structure, a reserved plate strip and caulking glue. The structural beam is the main structure of the original building; the anchoring structure is composed of an anchor plate and anchor bolts, which are used to fix the structural beam and position the "H"-shaped steel; the connection structure is composed of a connecting steel plate and bolts, the end of the connecting steel plate is welded to the anchor plate or "H"-shaped steel, and the connecting steel plate and the "H"-shaped steel are connected by bolts; the "H"-shaped steel is used to connect the two ends of the structural beam and serve as a supporting member for the upper load; the reserved plate strip serves as the base of the upper guide wall; the caulking glue is used to fill the gap between the "H"-shaped steel and the reserved plate strip.
[0005] Furthermore, the anchoring structure consists of an anchor plate and anchor bolts. The thickness of the anchor plate is 14 mm. The anchor bolt material is a chemical anchor bolt with a specification of M16. The horizontal spacing of the anchor bolts is 70 mm, and the vertical spacing is 70 mm. The anchor bolts are plug-welded with the anchor plate.
[0006] Furthermore, the material of the “H”-shaped steel is Q345B, which is used to bear the upper load.
[0007] Furthermore, the connection structure is composed of a connecting steel plate and bolts. The thickness of the connecting plate is 8mm, and the end is fully welded to the anchor plate. The bolt material is a high-strength bolt with a specification of M12 and a bolt spacing of 160mm. It is mechanically connected and fixed to the "H" steel.
[0008] Furthermore, the reserved slab is made of plain concrete, the strength of which meets the design requirements, and the width of which is the same as the width of the upper guide wall.
[0009] The beneficial effect of this utility model is that it solves the problems of traditional cast-in-place beam support with complicated procedures and long construction period. The use of steel structure combined with plate strip reservation can reasonably shorten the construction period and improve construction efficiency while ensuring construction safety. It is easy to promote in the field of building reinforcement construction, which can effectively reduce costs and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
