Embodiment Construction
[0071] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0072] Embodiments of the present invention and concrete steps thereof are as follows:
[0073] Such as image 3 and Figure 4 As shown, the slab-type two-way load-bearing keel frame is mainly composed of the main truss extending along the first direction and the secondary truss extending along the second direction. The first direction and the second direction are on the same plane and perpendicular to each other. The main truss and the secondary truss have the same structure as figure 1 and figure 2 As shown, all include 1 / 4 of the truss upper chord profile, 2 / 5 of the truss lower chord profile and 3 / 6 of the truss diagonal web bar; / 4. The truss lower chord profiles 2 / 5 are arranged in parallel and spaced up and down respectively, the truss upper chord profiles 1 / 4 and the truss lower chord profiles 2 / 5 are connected by multiple oblique web bars,...

The invention discloses a deformation control method of a plate-type two-way load-bearing keel frame. Including plate-type two-way load-bearing keel frame, including two primary and secondary trusses arranged in perpendicular directions, both including truss upper and lower chord profiles and truss diagonal bars; the upper and lower chord profiles of the truss are connected by W-shaped truss diagonal bars; The planar trusses are arranged in two-way vertical intersections to form a truss grid; using steel materials, first obtain the three stiffnesses of the plate-type two-way load-bearing frame; The maximum deflection of the slab of the skeleton; the maximum deflection of the slab is compared with the first and second preset deflection thresholds to regulate the deformation of the slab bidirectional load-carrying frame. The invention has high degree of industrialization, standardization of materials, wide range of product applications, reduced cost, solves the problem of deflection control of bidirectional bearing trusses, solves the problem of engineering efficiency, and realizes the calculation and control of bidirectional anisotropic deflection.
Description
technical field [0001] The invention belongs to the technical field of construction engineering and relates to a two-way load-bearing truss, in particular to a method for controlling the deformation of a plate-type two-way load-bearing dragon frame. Background technique [0002] In the existing technical field of construction engineering, in order to have a certain out-of-plane bending bearing capacity, most of the various plate components need to be formed by combining metal wires and bonding materials (such as reinforced concrete floor slabs, etc.) or by setting various keels (such as lightweight The combination of steel keel and cladding panels, etc.), the processing and forming of such plate components are relatively complicated. [0003] In reinforced concrete floor slabs, it is necessary to connect steel bars and concrete into a composite member through the gripping force of concrete to form a plate member with bending resistance to bear external loads. In reinforced ...
