Abstract
The utility model relates to a reinforced guy rope intersecting joint. The intersecting joint comprises a main pipe, a branch pipe and a lug plate, wherein the branch pipe is welded with the main pipe; two grooves are formed on the main pipe up and down; the lug plate is inserted into the groove of the main pipe and welded with the main pipe; a round steel pipe or square steel pipe is used as the main pipe; a casing can be arranged for reinforcement when larger force is stressed; the round steel pipe or the square steel pipe is used as the branch pipe; and a pin shaft hole which is a circular hole or elliptical hole is formed on the lug plate. The intersecting joint has the advantages of attractive structural appearance and direct and definite force transfer, and is convenient and easy to construct, prevents problem that manufacturing cost is increased due to the adoption of a cast steel joint, fully meets the requirements of structural stressing and is particularly suitable for a connecting joint between the guy rope and a main structure in a pre-stress space structure such as a diagonal structure, a cable-supported structure and the like.
Description
Technical field
The utility model relates to slant-pull structure, string in a kind of building structure and props up the drag-line in the Prestressed Space structures such as structure and the connected node of main structure, more specifically, relates to a kind of reinforced type drag-line tubular joint.
Background technology
The class main node that slant-pull structure, string prop up in the Prestressed Space structures such as structure is the node that drag-line is connected with structure, and the design of its node is the key of total system.For this category node, maximum characteristics are that the stretch-draw end or the fixed end of drag-line is attached thereto, and should be convenient to during design install and stretch-draw.Existing node commonly used has bolted spherical node, welded hollow spherical joints and tubular joint etc. in the engineering.Bolted spherical node is not suitable for welding a steel pipe or otic placode connects drag-line, can cause stress to concentrate again with the direct anchoring of drag-line, can not bear oblique pulling bigger in the design, so seldom use in the engineering.Using the node that connects drag-line in the space structures in the engineering has welded hollow spherical joints, and the steel pipe by one section band of welding otic placode on ball node is connected otic placode with bearing pin with drag-line.Can be distributed to several nodes to pulling force when the drag-line pulling force is big, but it is very complicated to do stressed meeting like this, power transmission is also indeterminate.Under the prerequisite of not disperseing pulling force, welded spherical node must have enough big diameter if want to bear bigger oblique pulling, and cost can be than higher like this.And tubular joint is also used in space structures to some extent, and major part is the tubular joint of cast steel.Cast steel node is suitable for the node of moulding complexity, by factory's integral cast, and steel pipe and otic placode, steel pipe casts in steel pipe, can satisfy the connection request of drag-line, can effectively reduce stress simultaneously and concentrate.But it also has weak point, promptly manufacturing processing technic is required strictness, and in present this stage, the construction period is longer, and cost is higher.
The utility model content
In order to overcome deficiency of the prior art, the utility model provides a kind of reinforced type drag-line tubular joint, and the casting before its handle in the tubular joint changes welding into, and its otic placode directly passes the person in charge, welds together with the both sides of being responsible for up and down respectively.
The technical solution of the utility model is as follows:
A kind of reinforced type drag-line tubular joint comprises the person in charge, arm and otic placode, and described otic placode and arm all are welded to connect with the person in charge.
Preferably, have the twice groove on the described person in charge, described otic placode inserts by groove and is responsible for, and is welded to connect with the person in charge.
Preferably, described otic placode is provided with pin shaft hole.
Preferably, described pin shaft hole is circular hole or elliptical aperture.
Preferably, described arm is provided with a row or multi-row, and every row is provided with one or more.
Preferably, described otic placode is provided with two.
Preferably, be responsible for and be provided with reinforcing sleeve and strengthen.
Preferably, the described person in charge adopts round steel pipe or square steel pipe, and described arm adopts round steel pipe or square steel pipe.
The beneficial effects of the utility model are: oblique pulling can be directly pass to below being responsible for and being responsible for each above arm by otic placode, pass on the following rod member by arm again, structure construction is succinct, the outward appearance grace, power transmission directly, clearly, easy construction, greatly reduce cost, shortened the duration, the cost of having avoided adopting cast steel node and having caused increases problem, and can fully satisfy the requirement of structure stress, be specially adapted to slant-pull structure, string and prop up the drag-line in the Prestressed Space structures such as structure and the connected node of main structure.

The specific embodiment
Embodiment one: shown in Fig. 1-4, reinforced type drag-line tubular joint comprises the person in charge 1, arm 2 and otic placode 3, be responsible for 1 and adopt round steel pipe, arm 2 adopts round steel pipe, otic placode 3 adopts solid steel plate, have the twice groove on the described person in charge 1, described otic placode 3 inserts by groove and is responsible for 1, adopts melt-through weld 5 to be welded to connect with the person in charge 1; Arm 2 adopts first fillet weld 6 to be welded to connect with the person in charge 1; Otic placode 3 is provided with pin shaft hole 4, and pin shaft hole 4 is circular hole or elliptical aperture, and the size of pin shaft hole 4 is bigger slightly than the bearing pin size that connects drag-line, so that install; Be responsible for 1 and be provided with three row's arms 2, every row's arm 2 is provided with three.
Embodiment two: as shown in Figure 5, be that with embodiment one difference otic placode 3 is provided with two, a row in the middle of arm 2 cancellations is provided with two row's arms 2 altogether, conveniently connects drag-line respectively in the both sides of being responsible for up and down, and it is shared to insert two otic placodes 3 of part of being responsible for.
