Abstract

The utility model relates to a novel early disassembling template support head, belonging to the field of a construction template member. The novel early disassembling template support head is composed of a top plate, a rod seat, and a plug. The novel early disassembling template support head depends on the spiral lifting and lowering of an adjusting nut on an adjusting rod to control the lifting and lowering of a beam support to achieve the purpose that a template is early disassembled in the construction of a cast-in-place floor plate. The novel early disassembling template support head is suitable for the template support systems of various frame materials. A large numbers of mould building investment can be saved, engineering cost is reduced, and a construction period is shortened.

Description

Early demountable form strut head

A kind of early stripping formwork system supporting member belongs to the construction formwork member.

In cast-in-place concrete floor construction, as the method for operating of the wire rack material formwork system of cast-in-situ floor load-bearing and maintenance and quality, duration and the cost that turnaround speed directly affects building structure construction.At present, the limitation of the Early dismounted shuttering column head that uses in the early stage form removal technology of domestic cast-in-situ concrete (Chinese patent application number 89208740.4) is bigger, only be applicable to steel wood gang form system, some construction departments must purchase a complete set of steel wood gang form and original other wire rack material formwork is on the shelf again, just can carry out the early stage form removal construction of cast-in-place concrete floor, this certainly will increase engineering cost greatly.In addition, because existing this Early dismounted shuttering column head is to articulate by the girder truss termination that the edge of a wing of corbel on the column cap and modulus are fixed, so the putting position that supports is required very harsh, and when institute between building a house depth and the standard width of a room in an old-style house not simultaneously, not only make the fragmentary assembly mould processing of floor and metope corner loaded down with trivial details, also can cause template and template, template and girder truss, template and column cap, the seam between the girder truss is more, makes the planeness of concrete floor bottom surface be affected.Descend owing to this column cap knocks to make the supporting plate translation realize corbel and drive girder truss by level again,,, when producing spillage, supporting plate is moved be obstructed, make troubles to construction if joint treatment is not very so the vibration in the operating process is bigger.

The purpose of this utility model provides a kind of fitting and is used with different wire rack material formwork systems, but flexible arrangement is set a roof beam in place, template, the early stripping formwork system supporting member that constructing operation is safe and simple.

For achieving the above object, the utility model has replaced existing percussive to descend with spiral decline.

Be described further below in conjunction with accompanying drawing:

Fig. 1 is an early stripping formwork system supporting member structural representation,

Wherein: 1. top board; 2. adjusting rod; 3. corbel; 4. pad; 5. adjusting nut; 6 sockets; 7. plug;

Fig. 2 is early stripping formwork system supporting member use principle figure,

Wherein: 8. regulate the seam plate; 9. composite board;

Fig. 3 is the local schematic diagram of arranging of early stripping formwork system

Mainly consisted of by 7 parts by early stripping formwork system supporting member shown in Figure 1, in use, the plug (7) of early stripping formwork system supporting member is inserted in the vertical support, top board (1) withstands on adjusting seam plate (8) and locates, girder is placed on the corbel (3), secondary beam is arranged on the girder, makes the shut die system layout shown in Fig. 2 (a) by adjusting nut (5) and adjusting rod (2). When concrete reach design strength 50% the time, with adjusting nut (5) downward modulation 10--15 centimetre, corbel (3) is descended, girder, secondary beam and multi-layer sheet (9) be corresponding falling also, sees shown in Fig. 2 (b), and at this moment supporting member top board (1) still keeps motionless with adjusting seam plate (8), support concrete floor, the primary and secondary beam of pulling down and multi-layer sheet namely can be used for turnover, when treating that floorslab concrete reaches the 70--100% of design strength, remove and support and regulate the seam plate.

Because the utility model adopts spiral lift, and the bottom surface of corbel also can be designed to by particular requirement step-likely, and therefore, vertical direction can be used according to the scene difference of multi-layer sheet thickness and primary and secondary depth of beam, the vertical height of flexible modulation shut die system. Again because in the horizontal direction, the primary and secondary beam can carry out cross-lapping by corbel, see shown in Figure 3, so just can be according to the difference of room depth and the standard width of a room in an old-style house, the fragmentary assembly mould of corner is transferred to according to the needs of support arrangement regulates seam plate place, overcome when the different and fragmentary piece in corner of absolute altitude is arranged at the bottom of beam floor and the variable cross-section floor plate, many troublesome problem of bringing to formwork, make the layout of cast-in-situ floor shut die system more flexible, and effectively reduced the floor seam, improved construction quality.

The utility model is applicable to used wire rack material formwork support system in the various cast-in-situ floor constructions, as the card system of shutting out, profit are built template system, steel pipe scaffold and door type frame etc., only need in the support of these shut die systems, to insert this early stripping formwork system supporting member that the utility model provides, just can reach the purpose of early tearing open. Namely save a large amount of shut die investments, reduced engineering cost, shortened the construction period again, had significant economic benefit.

Claims

1, tears supporting member a kind of morning open, by top board (1), socket (6), plug (7) constitutes, it is characterized in that the adjusting rod (2) between top board (1) and socket (6) is threaded, be with adjusting nut (5) on the adjusting rod (2), adjusting nut (5) and corbel (3) are added with pad (4) between propping up, the bottom surface of corbel (3) can be a level, also step can be arranged.
