Abstract

The utility model discloses a welded tensioning device, and belongs to the technical field of bridge construction. The welded tensioning device comprises a base, a panel and reinforcing ribs. The panel is perpendicularly fixed to one end of the base, and the base and the panel are made of rectangular steel plates. Rib penetrating holes are formed in the middle of the panel and are round, and the diameter of the rib penetrating holes is 3-4cm. The reinforcing ribs are made of right triangle steel plates, and the two right-angle sides of the reinforcing ribs are connected with the base and the panel respectively. The thickness of the panel is 1.4-2.6cm. The tensioning device is of a welded type, and auxiliary tools such as supports do not need to be erected. The welded tensioning device has the advantages of being simple in structure, convenient to manufacture, and beneficial for fast construction.

Description

A kind of welded type tensioning equipment
Technical field
The utility model belongs to technical field of bridge construction, more particularly, relates to a kind of welded type tensioning equipment.
Background technology
In the prestressed steel structure of civil engineering, rope membrane structure, curtain wall rope bar supporting construction, all there is drag-line need to apply prestressing force.Drag-line can be the various ways such as the parallel twisting of high-strength steel tow, the assembling of many steel strand or rod iron pull bar.At present, drag-line being applied to prestressed main method both at home and abroad is at the sandwiched force transmission beam in the shoulder place of stay cable end rope head, in the both sides of drag-line cable body, two or many hydraulic jack are arranged symmetrically on the force transmission beam of rope head both sides, synchronously the rope head is applied to stretching force with the feed-through hydraulic jack, and can rotate the branch sleeve that positive and negative tooth is arranged in the drag-line adjusting screw(rod) simultaneously, Jiang Suotou is fixed in the anchoring otic placode and keeps required stretching force in cable body.For example: China Patent No. is 200910196949.2, open day is on May 12nd, 2010, the patent document that a name is called a kind of tensioning equipment is disclosed, a kind of tensioning equipment, comprise holder and sliding seat, be provided with on holder and be convenient to the connecting portion that reinforcing bar or steel strand pass, on sliding seat, be provided with for locking the locking device of reinforcing bar or steel strand, it is characterized in that, the connecting portion place of described holder is provided with an enclasp device, described enclasp device comprise one by some cone keies, formed hold part tightly, with for described, holding the seat of holding tightly that part matches tightly, hold tightly in seat and be provided with bellmouth.This beneficial effect of the invention is: this invention, by setting up an enclasp device, comes off to prevent reinforcing bar or steel strand.This invention is simple and compact for structure, practical.
But, adopt above-mentioned stretching construction device to have the following disadvantages, before the stretch-draw operation, need to set up scaffold, after the stretch-draw end of job, need to remove scaffold, to waste time and energy, the cycle of stretch-draw operation is longer, and efficiency is low.
Summary of the invention
the problem that 1, will solve
For the above-mentioned problems in the prior art, the utility model provides a kind of welded type tensioning equipment, and it is a kind of welded type, without the tensioning equipment of the aids such as erection bracket, simple in structure, easy to make, is conducive to rapid construction.
2, technical scheme
In order to address the above problem, the technical scheme that the utility model adopts is as follows:
A kind of welded type tensioning equipment, comprise base, also comprises panel and reinforcing rib, and described panel vertically is fixed in an end of base; Described base, panel are made by rectangular steel plates; Described panel middle part has wears the muscle hole, and the described muscle hole of wearing is circular port, and its diameter is 3-4cm; Described reinforcing rib is made by the steel plate of right-angled triangle, and its two right-angle side is connected with panel with base respectively; The thickness of described panel is 1.4-2.6cm.
Further, described reinforcing rib has 4.
Further, the described muscle hole of wearing has 15-31.
3, beneficial effect
Than prior art, the beneficial effects of the utility model are:
(1) panel that the utility model is used band to wear the muscle hole is directly welded on stretch-draw girder steel body, without the tensioning equipment of the aids such as erection bracket, simple in structure, easy to make, is conducive to rapid construction;
(2) the utility model is provided with 4 reinforcing ribs, guarantees that panel can not deform in stretching process;
(3) the utility model is provided with 15-31 and wears the muscle hole, can construct flexibly according to the quantity of fining twisted steel.
The accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
In figure: 1, base; 2, panel; 3, reinforcing rib; 4, wear the muscle hole.
The specific embodiment
Below in conjunction with specific embodiment, the utility model further is described.
embodiment 1
As shown in Figure 1, a kind of welded type tensioning equipment, comprise base 1, panel 2 and reinforcing rib 3, and panel 2 vertically is fixed in an end of base 1; Base 1, panel 2 are made by rectangular steel plates; Panel 2 middle parts have wears muscle hole 4, wears muscle hole 4 for circular port, and its diameter is 3cm; Reinforcing rib 3 is made by the steel plate of right-angled triangle, and its two right-angle side is connected with panel 2 with base 1 respectively; The thickness of panel 2 is 1.4cm; Reinforcing rib has 4; Wear the muscle hole and have 23
During use, directly the panel of this tensioning equipment 2 is welded on the body of stretch-draw girder steel, and makes to wear muscle hole 4 and aim at and wear the muscle groove on the girder steel bodies, after carry out stretching construction; After stretch-draw finishes, dismountable.
embodiment 2
With embodiment 1, difference is, the diameter of wearing muscle hole 4 is 3.4cm, and the thickness of panel 2 is 2cm, and wearing the muscle hole has 15.
embodiment 3
With embodiment 1, difference is, the diameter of wearing muscle hole 4 is 4cm, and the thickness of panel 2 is 2.6cm, and wearing the muscle hole has 31.
Below schematically the utility model and embodiment thereof are described, this description does not have restricted, and shown in accompanying drawing is also one of embodiment of the present utility model, and actual structure is not limited to this.So, if those of ordinary skill in the art is enlightened by it, in the situation that do not break away from the utility model, create aim, without the creationary frame mode similar to this technical scheme and the embodiment of designing, all should belong to protection domain of the present utility model.
