The rapid disassembly device comprises a steel keel and formwork fixing plates arranged on both sides of the steel keel, wherein the bottom surface of the steel keel is at least provided with two hydraulic jacks for adjusting the steel keel and the formwork fixing plates to move up and down; the hydraulic jacks are connected with a control system; and the formwork fixing plates are L-shaped steel plates, and are fixed on both sides of the steel keel through pins. Due to the adoption of the technical scheme, the rapid disassembly device has the advantages of simple structure, uniform stress, high stability, easiness in disassembling and assembling, high turnover efficiency, high economic efficiency, practicability and suitability for floor formwork supporting and operating platforms.
Description
Technical field
The utility model belongs to construction engineering technical field, relates in particular to the fast attaching/detaching apparatus of a kind of ribbed slab floor formwork in work progress.
Background technology
At the realm of building construction, the bracing or strutting arrangement of ribbed slab floor adopts formwork, flitch, frame pipe etc. usually at present, and the frame pipe withstands formwork through the flitch on top; Firm in order to support, adopt a large amount of formworks, flitch, frame pipe usually, this just makes and installs, the form removal system needs great amount of manpower and time; And need tear frame pipe form removal shell more earlier open during dismounting; Behind complete removal, just can use, this just makes the turnover life cycle of formwork prolong.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of concrete floorslab formwork device for quickly disassembling is provided.
For realizing the purpose of the utility model, adopt following technical scheme:
A kind of concrete floorslab formwork device for quickly disassembling; Comprise steel joist and the formwork fixed head that is arranged on the steel joist both sides; Under the steel joist bottom surface, be provided with two hydraulic jack at least, be used to regulate steel joist and the formwork fixed head moves up and down, hydraulic jack is connected with the control system.
Above-mentioned concrete floorslab formwork device for quickly disassembling, said formwork fixed head is the L shaped steel plate, through the both sides of dowel fixes at steel joist.
Above-mentioned concrete floorslab formwork device for quickly disassembling is provided with reinforcing rib between two plates of said L shaped steel plate.
Above-mentioned concrete floorslab formwork device for quickly disassembling, said formwork fixed head is an angle steel.
Above-mentioned concrete floorslab formwork device for quickly disassembling; Under the bottom surface of steel joist, be fixed with base and vertical ribs; Base fits together with vertical ribs, and the top of hydraulic jack contacts with the bottom of base, and base is arranged on the center line of steel joist bottom surface with vertical ribs; On the bottom surface of steel joist, also be provided with horizontal ribs, laterally ribs is vertical each other with vertical ribs.
Above-mentioned concrete floorslab formwork device for quickly disassembling, the bottom of hydraulic jack is placed on the heelpiece.
Adopt technique scheme, the utility model has following advantage: the utility model is simple in structure, and is stressed even, good stability, and dismounting is simple, and all transfer efficients are high, and are economical and practical, support and operating platform applicable to floorslab formwork.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the schematic bottom view of steel joist.
Fig. 3 is that the utility model supports the formwork structural representation.
The specific embodiment
A kind of concrete floorslab formwork device for quickly disassembling as depicted in figs. 1 and 2; Comprise steel joist 2 and the formwork fixed head 3 that is arranged on the steel joist both sides; Under steel joist 2 bottom surfaces, be provided with two hydraulic jack 4 at least; Be used to regulate steel joist 2 and formwork fixed head 3 moves up and down, hydraulic jack 4 is connected with the control system, and the control system controls many tools hydraulic jack and moves up and down with stroke synchronously.
The used formwork fixed head 3 of the utility model is L shaped steel plates, through pin 1 be fixed on steel joist both sides, in order to save raw material, need not special thick steel plate, between two plates of L shaped steel plate, be provided with reinforcing rib 6, just can reach designing requirement.
In order to save the manufacturing process of formwork fixed head, the preferred plan of the utility model is: the formwork fixed head adopts angle steel, and directly buying just can be used.
The utility model is for stressed even; Under the bottom surface of steel joist, be fixed with base 7 and vertical ribs 8; Base 7 fits together with vertical ribs 8, and the top of hydraulic jack 4 contacts with the bottom of base 7, and base 7 is arranged on the center line of steel joist bottom surface with vertical ribs 8.In order to prevent angle steel side pressure distortion, on the bottom surface of steel joist, also be provided with horizontal ribs 9, it is mutual vertical with vertical ribs 8 laterally to strengthen 9 ribs.
The utility model is operated for ease, and the bottom of hydraulic jack 4 is placed on the heelpiece 5.
The course of work of the utility model is following: the utility model concrete floorslab formwork device for quickly disassembling is taked the early removing system of " first form removal shell, then tear hydraulic jack open ", thereby accelerates the turnover of formwork.Wherein, steel joist is a 60mm x 100mm rectangle girder steel, forming with 3mm steel plate compacting, at a distance from 400mm one section horizontal steel pipe 7 of 20mm is set along steel joist is vertically every, as pin hole, and steel joist is played a supportive role, in case the side pressure distortion; Angle steel is L50mm X 5mm, along the elongated setting of steel joist, and pin diameter 18mm, hydraulic jack is same model, and by the operation of control system synchronization.In order to withstand steel joist better, the bottom surface of steel joist is provided with base and vertical ribs, and is stressed so even.
Formwork 10 installation processes are following: formwork 10 is emitted on the formwork fixed head of steel joist both sides successively; Can regulate hydraulic jack according to the placement location of formwork; Make the formwork fixed head just withstand formwork,, between formwork and formwork fixed head, add foaming adhesive tape jam-packed for preventing spillage; And after adding the foaming adhesive tape, formwork is removed be more prone to.
Formwork 10 demolishing process are following: tear open and strike down earlier pin when touching, the form removal fixed head prizes with special-purpose crowbar gently, pulls down formwork 10; Phoresy to flooring, clean out, the brushing release agent; Being transported to the stacking place again puts well; Remove hydraulic jack and steel joist then, form removal speed like this is fast, has effectively accelerated the turnover of formwork.
