Abstract
The utility model discloses a support between two limbs lattice column posts, include: the two spinal branch vaulting poles of perpendicular setting, the bracing piece includes mobile jib, branch and gusset plate, divide the both ends rigid connection that branch passed through gusset plate and mobile jib, form two Y type structures, the mobile jib cross of two spinal branch vaulting poles is arranged and is adopted and to pass through the welding seam mutually and form each other and be articulated the connection. The supporting structure between the double-limb lattice column is simple, the load transmission is clear, and the double-limb lattice column has the technical and economic advantages of high bearing capacity, small steel consumption, convenience in construction, low manufacturing cost, attractive appearance and the like.
Description
Technical Field
The utility model provides a support between two limbs lattice column posts is applicable to the central bearing structure of two limb posts of lattice formula pipe.
Background
In order to ensure the normal operation of the load-bearing structure of the steel structure building, an inter-column support is generally required to be arranged between the longitudinal columns of the steel structure building, and the inter-column support is used for ensuring the longitudinal stability of the steel structure building and determining the calculated length of the steel column outside a plane. The existing forms of the support between the columns mainly comprise the following four forms: 1) the cross-shaped cross support has direct force transmission, simple structure, less material consumption and high rigidity, and is a common form; 2) the hollow door-shaped support is made of more materials and has poorer rigidity, and is only adopted when a door opening is arranged at the position or equipment is placed; 3) splayed supports, which are used when the ratio of the column pitch to the height of the support between the columns is greater than 2.5; 4) herringbone bracing is employed when the ratio of column pitch to the height of the bracing between columns is greater than 1.5. Overhead coal conveying trestle support is steel frame center bearing structure usually, because steel tubular construction appearance is pleasing to the eye to the cross-section distribution level difference is little, and two limb steel-pipe columns of lattice formula are often adopted, but, because the limb interval of two limb lattice columns is nearer, if every limb post all sets up the center and support then the interval of support is too little, and the inconvenient and appearance of construction is pleasing to the eye inadequately.
Therefore, the development of a novel supporting structure between columns of the double-limb lattice column is a problem to be solved urgently.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention provides a dual-limb lattice column support to solve the above problems.
The utility model provides a technical scheme is: a dual-limb lattice column support comprising: the two spinal branch vaulting poles of perpendicular setting, the bracing piece includes mobile jib, branch and gusset plate, divide the both ends rigid connection that branch passed through gusset plate and mobile jib, form two Y type structures, the mobile jib cross of two spinal branch vaulting poles is arranged and is adopted and to pass through the welding seam mutually and form each other and be articulated the connection.
Preferably, the main rod and the branch rods are hot-rolled steel pipes.
More preferably, the gusset plate is a hot-rolled steel plate.
The utility model provides a support between two limbs lattice column posts and be cross support, by the mobile jib, divide branch and gusset to constitute, in the steel shotcrete calculation plane, the mobile jib each other is articulated to be connected, and the member calculates 1/2 that length is axis length, and outside the steel shotcrete calculation plane, the calculation length of member equals axis length. The supporting rod is changed into two branches at the end part, a node plate is arranged between the branch rods, the main rod and the branch rods are rigidly connected, axial force and shearing force can be transmitted, and the inter-column support is divided into two limbs at the end part and is hinged with each limb column of the double-limb lattice column through a penetration welding line.
The utility model provides a support between two limb lattice column posts, simple structure, the load transmission is clear and definite, has the technical and economic advantages such as bear the weight of the dynamic height, the steel quantity is little, construction convenience, low in cost, appearance are pleasing to the eye.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and embodiments:
fig. 1 is a three-dimensional perspective view of a dual-limb lattice column support provided by the present invention;
fig. 2 is a plan view of the support between the columns of the dual-limb lattice column provided by the present invention;
FIG. 3 is a connection diagram between the main rods;
fig. 4 is a connection diagram of the main rod and the branch rod.
Detailed Description
The invention will be further explained below with reference to specific embodiments, without limiting the invention.
As shown in fig. 1 to 4, the utility model provides a support between two limbs lattice column posts, include: two spinal branch vaulting poles of perpendicular setting, the bracing piece includes mobile jib 1, branch 2 and gusset plate 3, divide branch 2 to pass through the both ends rigid connection of gusset plate 3 with mobile jib 1, form two Y type structures, and 1 cross-arrangement of mobile jib of two spinal branch vaulting poles just adopts to pass through the welding seam mutually and form each other and articulate the connection, and is preferred, mobile jib 1 is the hot rolling steel pipe with branch pole 2, gusset plate 3 is hot-rolled steel plate.
The support between the two-limb lattice column is a cross-shaped cross support and is composed of a main rod, branch rods and a node plate, wherein the main rods are hinged with each other in a steel support calculation plane, the calculated length of each rod is 1/2 of the length of the axis, and the calculated length of each rod is equal to the length of the axis outside the steel support calculation plane. The supporting rod is changed into two branches at the end part, a node plate is arranged between the branch rods, the main rod and the branch rods are rigidly connected, axial force and shearing force can be transmitted, and the inter-column support is divided into two limbs at the end part and is in hinged connection with each limb column 4 of the double-limb lattice column through a penetration welding line.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
