Abstract

This invention belongs to the field of railroad construction, more directly, to the post-crane track device of the tower cranes.Purpose: to cheapen the post-crane track device, to decrease the labour costs involved with the equipment, and to economize inert substances.It comes through equipping cross post-crane ferro-concrete panels with a trough gully. The panels are set with the side edges close to each other, composing a chamfer for a gritty substratum. The gritty substratum acts as the lining and the even load distribution to the longitudinal mudsills with railing.

Description

Išradimas priskiriamas geležinkelio statybos sričiai, betarpiškai bokštinių kranų pokraninio kelio įrengimui.The invention relates to the field of railway construction, directly to the installation of a post-crane track for tower cranes.

Žinomas išradimas Viršutinio kelio statinio ant gelžbetoninių pobėginių pagrindų įrengimas (TSRS a.l. 1461810), turintis išilginius gulekšnius, sujungtus skersiniais brusais. Šio išradimo trūkumas tame, kad pagrindo įrengimui naudojamos medžiagos žvyras arba skalda tik iš dalies gali būti panaudojama pakartotinai, o didesnė šių medžiagų dalis pasiskleidžia aikštelėje ir įsispaųdžia į gruntą ir toliau nebepanaudoj ama.BACKGROUND OF THE INVENTION Installation of an upper road structure on reinforced concrete track bases (USSR a.l. 1461810) having longitudinal gullets connected by transverse beams. A disadvantage of the present invention is that the gravel or crushed material used for the foundation installation can only be partially reused, and the greater part of these materials is spread on the site and pressed into the soil and is no longer used.

Išradimo tikslas - pokraninio kelio įrengimo atpiginimas, darbo sąnaudų sumažinimas jų įrengimui.The object of the invention is to reduce the cost of installing a post-crane road, and to reduce labor costs for its installation.

Tikslas pasiekiamas įrengiant skersines pokranines gelžbetonines plokštes su lovine įlaja. Plokštės dedamos viena greta kitos šoninėmis briaunomis, sudarydamos lovį smėlinio pasluoksnio įrengimui. Smėlio pasluoksnis tarnauja išlyginimui ir išilginių gulekšnių su bėgiais tolygiam krūvio paskirstymui.The objective is achieved by installing transverse post-mortem reinforced concrete slabs with a trough. The panels are placed side by side along the edges, forming a trough for sandblasting. The sand bed serves for leveling and evenly distributing the load on the longitudinal sleepers with rails.

Išradimo esmė ta, kad skersinės plokštės pagamintos su įlajomis smėlio pasluoksnio po išilginiais gulekšniais įrengimui.The essence of the invention is that the transverse plates are made with slabs for the installation of a sand layer under the longitudinal beds.

Siūlomo išradimo privalumas tas, kad įrengiant pokraninius kelius, nebereikalingas žvyras arba skalda, tarnaujantys pokraninio kelio balastu. Baigus statybą, pokraninio kelio pagrindas iš gelžbetoninių plokščių su smėlio pasluoksniu lengvai išardomos ir panaudojamas kitų pokraninių kelių įrengimui. Tokiu būdu atsiranda galimybė daugkartiniam pokraninio kelio pagrindo panaudojimui, žvyro bei skaldos taupymui.An advantage of the present invention is that no gravel or rubble serving as a ballast for post-crane roads is required when installing aftermarket roads. After construction, the foundation of the post-crane road is easily disassembled from reinforced concrete slabs with sand layer and used for installation of other post-crane roads. In this way, it is possible to reuse the foundation of the postcranial road and save gravel and crushed stone.

Pagrindinis skirtumas yra tas, kad skersinė plokštė turi lovinę įlają smėlio pagalvės įrengimui, kuri tolygiai paskirsto apkrovas ir išlygina išilginius gulekšnius. Pokraninis kelias įrengtas ant pokraninės plokštės su smėlio pasluoksniu yra visiškai surenkamas ir išardomas.The main difference is that the transverse plate has a trough for the installation of a sand pillow, which evenly distributes the loads and smooths the longitudinal beds. The post-mortem path installed on the post-mortem slab with sand layer is completely prefabricated and dismantled.

Brėžinyje parodytas pokraninės plokštės skersinis pjūvis: skersinė plokštė 1, turinti lovinę įlają 2, į kurią pilamas smėlio pasluoksnis pasluoksnio uždėti išilginiai tvirtintais bėgiais 5.The drawing shows a cross-section of a sub-crane plate: a transverse plate 1 having a trough 2, into which a layer of sand is placed, with longitudinal rails 5 attached to the layer.

(pagalvė) 3. Ant smėlio gulekšniai 4, su priPokraninis kelias įrengiamas tokiu būdu: aikštelė išlyginama, dedamos gelžbetoninės plokštės 1 su lovinėm įlajom 2, į kurias užpilamas smėlio pasluoksnis (pagalvė) 3. Ant smėlio pasluoksnio 3 dedami išilginiai gulekšniai 4 su pritvirtintais bėgiais 5. Baigus statybos darbus, pokraninis kelias ir pagrindas išmontuojamas atgaline tvarka ir panaudojamas kituose objektuose.(cushion) 3. The sandbeds 4, with the pre-crane road, shall be arranged as follows: The site shall be leveled, reinforced concrete slabs 1 shall be placed with troughs 2, which shall be filled with a sand layer (pillow) 3. Longitudinal sleepers 4 with rails 5. Upon completion of the construction work, the sub-crane road and base shall be dismantled retrospectively and used in other facilities.

Daugkartinis gelžbetoninių pokraninių plokščių su smėlio pagrindu panaudojimas vietoje vienkartinių žvyro-skaldos pagrindų leidžia taupyti inertines medžiagas, mažinti darbe sąnaudas.Re-use of sand-based reinforced concrete post-slab panels instead of single-gravel-rubble foundations allows saving inert materials and reducing work costs.
