Abstract
The utility model relates to a hoisting bracket used for transporting and installing a special-shaped precast concrete module; the method is characterized in that: the device comprises a basic frame, an auxiliary support and a lifting lug arranged at the top of the basic frame; the foundation frame specifically comprises four upright posts (3), and a bottom beam (2) and a top beam (4) which are respectively used for connecting the upright posts (3); the auxiliary support comprises a triangular steel frame (1), the number of the auxiliary supports is four, the auxiliary supports are respectively arranged on the side portion of each upright post (3), and every two auxiliary supports are symmetrically arranged and are parallel to each other. This hoisting support utilizes the all-round shroud of module that basic frame will be hoisted, avoids the emergence of the condition such as concrete extrusion, deformation fragmentation at whole hoist and mount in-process, can utilize basic frame to do the module support bracket concurrently before the prefabricated module location of dysmorphism simultaneously, can avoid hoist and mount process module to empty, the cracked scheduling problem of deformation to appear through its auxiliary support, ensures whole hoist and mount process safety.
Description
Technical Field
The utility model relates to a concrete construction field specifically is a hoisting support that is used for special-shaped precast concrete module to fall fortune, installation.
Background
Traditional building is mostly cast in situ concrete, and along with the development assembly type building of science and technology is more and more, and the heterosexual structure also develops thereupon, and the hoist and mount of concrete dysmorphism prefabricated module also becomes the common mode of assembly type building structure development. The common hoisting mode of the prefabricated modules is hoisting by utilizing the structural characteristics of the modules, hoisting by wrapping steel wire ropes or hoisting by prefabricating steel bar hoisting rings on the modules, but the hoisting mode adopted for large-sized special-shaped concrete modules has certain danger in the hoisting process.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide a hoisting support suitable for large-scale special-shaped precast concrete module is had bad luck, is installed.
In order to achieve the above object, the present invention is realized as follows:
a hoisting support for transporting and installing a special-shaped precast concrete module; the device comprises a base frame, an auxiliary support arranged on the outer side of the base frame and a lifting lug arranged on the top of the base frame; the foundation framework is of a box-type structure and specifically comprises four upright columns, and a bottom beam and a top beam which are respectively connected with the upright columns; the auxiliary support comprises a triangular steel frame, the number of the auxiliary supports is four, the auxiliary supports are respectively arranged on the side portion of each upright column, each two auxiliary supports are symmetrically arranged in a group, and the two groups of auxiliary supports are parallel to each other.
This hoisting support utilizes the all-round shroud of module that basic frame will be hoisted, avoids the emergence of the condition such as concrete extrusion, deformation fragmentation at whole hoist and mount in-process, can utilize basic frame to do the module support bracket concurrently before the prefabricated module location of dysmorphism simultaneously, can avoid hoist and mount process module to empty, the cracked scheduling problem of deformation to appear through its auxiliary support, ensures whole hoist and mount process safety.
Drawings
Fig. 1 is a schematic structural view of the hoisting bracket.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1, a hoisting bracket for transporting and installing a special-shaped precast concrete module; the device comprises a base frame, an auxiliary support arranged on the outer side of the base frame and a lifting lug arranged on the top of the base frame; the foundation framework is of a box-type structure and specifically comprises four upright posts 3, and a bottom beam 2 and a top beam 4 which are respectively used for connecting the upright posts 3; the auxiliary support comprises a steel frame 1 in a triangular shape, the number of the auxiliary supports is four, the auxiliary supports are respectively arranged on the side portion of each upright post 3, each two auxiliary supports are symmetrically arranged in a group, and the two groups of auxiliary supports are parallel to each other.
This hoisting support is actually adopted following mode to consolidate: stiffening plates 6, 7 and 8 with the thickness of 20mm are arranged at the corresponding joint positions of the top beam 4, the bottom beam 2 and the upright post 3; the welding seams of the auxiliary support 1, the top beam 4, the bottom beam 2, the upright post 3 and the lifting lug 5 which are connected in pairs are all full penetration one-level welding seams.
The hoisting bracket should be sized in the following manner:
1. determining the outline dimension of the foundation frame according to the maximum length, width and height dimensions of the precast concrete module;
2. determining the length of parts except two sides of a foundation frame according to the aggregate size of the concrete special-shaped prefabricated modules, and determining the length of an auxiliary support according to the length of the outer parts, wherein the included angle of the auxiliary support is smaller than 45 degrees;
3. determining the position of a lifting lug 5 at the top of the basic frame according to the gravity center position of an object to be hoisted, welding the lifting lug 5 at the position of a middle web plate of the top beam 4, welding the lifting lug 5 with a full penetration weld of a double-sided groove of the top beam 4, symmetrically welding the lifting lug 5 relative to the gravity center position, welding the lifting lug 5 within the range of 1/4 at two ends of the top beam 4, and enabling the distance between the lifting lug and the side of the upright post 3 to;
4. PL200mm x 200 longitudinal stiffening plates 6 are welded at the connecting positions of the top beam 4 and the bottom beam 2 of the foundation frame and the upright posts 3, the thickness of the stiffening plates is not less than 20mm, fillet welds are welded, and the size of the weld angle is not less than 12 mm;
5. the distance between the bottom beam 2 of the foundation frame and the bottom of the hoisted concrete module is easy to be 200mm, the gap is supplemented by H-shaped steel, and the gap is connected with the bottom beam 2 of the foundation frame in a welding mode.
This hoisting support utilizes the all-round shroud of module that basic frame will be hoisted, avoids the emergence of the condition such as concrete extrusion, deformation fragmentation at whole hoist and mount in-process, can utilize basic frame to do the module support bracket concurrently before the prefabricated module location of dysmorphism simultaneously, can avoid hoist and mount process module to empty, the cracked scheduling problem of deformation to appear through its auxiliary support, ensures whole hoist and mount process safety.
