Abstract
The utility model relates to a fixture for anchoring screw spikes of a railway concrete sleeper. The fixture is poured to be formed at one time by using a casting die, and comprises an anchoring frame base, spike sleeves, a cross rib, handheld handles and strong magnets between the spike sleeves and the handheld handles. The fixture is high in positioning speed, easy to operate and powerful in control, construction processes are reduced, the construction progress is accelerated, and the construction cost is reduced. Practice indicates that deviation of the screw spikes from the centers of preformed holes is within the range allowed by the standard, and the degree of skewness is controlled to be within the range of less than 2 degrees; drawing force is a standard value of more than 60 KN; and the original work efficiency of pouring 200 screw spikes (pure pouring) for eight hours every day by a single person is improved to the work efficiency of pouring 500 screw spikes (pure pouring) for eight hours every day by the single person.
Description
Technical field
The utility model belongs to the railroad track field of engineering technology, is specifically related to II, III type concrete sleeper screw spike anchoring jig that track engineering ballasted track main flow is used.
Background technology
In Environment in Railway Engineering Construction, concrete sleeper is a great the work items of engineering quantity, calculates with one 20 kilometers railways, and railway spike anchoring amount just reaches 160,000.For a long time, screw spike anchoring adopts artificial hand to insert the anchor type of single railway spike hand-hole always, and along with the development of society, this traditional prepared screw-bolt hole job practices can not adapt to the needs of railway engineering construction.Often occur screw spike center line off normal in the construction, degree of skewness waits greater than the requirement of standard and pulling capacity inadequately influences the entity project quality problems.The mode of handling above-mentioned several types of problems is not simply to repair and repair, but the railway spike that railway spike is perfused with quality problems withdrawing in the hole comes out, and pour in clear again hole; And even will to pour into whole concrete sleeper of quality defects discarded because of railway spike; So, withdrawing railway spike and empty time-consuming, effort, and effect is extremely low; Programming and cost have all been caused and adverse influence, and caused the waste of resource.
In recent years; Some units in charge of construction have utilized steel pipe and reinforcement fabrication some easy screw spike locating racks are applied to the pouring construction of screw spike, because the locating rack design is simple and easy; It is thorough inadequately that the location is provided with; It is not enough that firmware is made precision, causes the quality of railway spike anchoring and effect still not to be ensured to greatest extent, can't apply.
Through engineering practice, the utility model is developed and a kind ofly can be guaranteed the requirement of railway spike anchoring physical dimension, is convenient to construction and the fast again novel sleeper screw spike anchoring jig of effect again.
Summary of the invention
The purpose of the utility model is the weak point that has overcome existing screw spike pouring construction; A kind of easy to operate, construction cost is low, anchoring effect is good sleeper screw spike anchoring jig is provided; This jig has reduced working procedure; Accelerate construction speed, reduced construction cost, and reliable construction quality.
The technical scheme of the utility model is: adopt casting mould that the disposable perfusion of jig is shaped; Jig comprises anchor frame base, railway spike sleeve, cross rib, hand holding handle; The railway spike sleeve of two symmetries is connected on the anchor frame base; Between two railway spike sleeves, cross rib is arranged, the strong magnets between railway spike sleeve and hand holding handle.
Adopt the technical scheme of the utility model, can pour into two screw spikes at every turn, working procedure has been reduced rapidly in the location, and is simple to operate, and control is strong, has accelerated construction speed, has reduced construction cost.Show that through engineering practice after screw spike is accomplished, the construction quality of the screw spike that poured into is inspected by random samples, screw spike departs from the preformed hole center in the deviation range that standard allows, degree of skewness has been controlled in the scope less than 2 degree.Pulling capacity is all greater than the normal values of 60KN.Work efficiency is brought up to 500 (pure perfusion) of perfusion 8 hours present every days by 200 (pure perfusion) of perfusion 8 hours original single every days.

Among the figure, 1-anchor frame base, the 2-hand holding handle, the 3-strong magnets, the 4-cross rib, 5-railway spike sleeve, 6-reinforces rod member, 7-strong magnets, 8-anchored end.
The specific embodiment
The screw spike anchoring jig is made: like Fig. 1, shown in 2; Adopt casting mould that the disposable perfusion of jig is shaped; Jig comprises anchor frame base 1, railway spike sleeve 5, cross rib 4, hand holding handle 2; The railway spike sleeves 5 of two symmetries are connected on the anchor frame base 1, in 5 in two railway spike sleeves cross rib 4 are arranged, in the strong magnets 3 of 2 of railway spike sleeve 5 and hand holding handles.Be illustrated in figure 4 as the screw spike structural representation, the centre is a strong magnets 7, and the lower end is an anchored end 8.
The railway spike sleeve can accurately be located railway spike centre distance, and effectively controls the verticality of railway spike perfusion, and the railway spike sleeve adopts aluminium to cast shape.Use seccotine that strong magnets is bonded to railway spike sleeve top.Strong magnets can effectively be controlled the insertion length of railway spike, and the moment that anchor frame is put into the railway spike hole is guaranteed that railway spike does not break away from because of own wt and anchor frame, can guarantee that again railway spike can easily separate after anchoring with anchor frame simultaneously.Hand holding handle is to be inserted in soft plastics with steel pipe, steel tube surface to constitute, and steel pipe and railway spike sleeve welded top, steel tube surface are inserted in soft plastics and are convenient to the jig of holding in the work progress.
Screw spike anchoring jig method for using: cleaning concrete sleeper bottom plug-hole, the non-anchored end of railway spike is inserted in the jig railway spike sleeve, pour the sulphur-bonded mortar that has machined into the railway spike hole, the sulphur-bonded mortar degree of depth is so that 3mm is advisable from the aperture; Behind the sulphur-bonded mortar perfusion hand-hole, the jig that will have railway spike immediately inserts the railway spike hole, leaves standstill 30 seconds, jig is taken out the sulphur-bonded mortar that cleaning hole overflows after 10 minutes outward.
Claims (2)
1. railway concrete sleeper screw spike anchoring jig; It is characterized in that adopting casting mould that the disposable perfusion of jig is shaped; Jig comprises anchor frame base, railway spike sleeve, cross rib, hand holding handle; The railway spike sleeve of two symmetries is connected on the anchor frame base, between two railway spike sleeves, cross rib is arranged, the strong magnets between railway spike sleeve and hand holding handle.
