Description

Downward-penetrating type vertical rod bottom support for stair area supporting frame

Technical Field

The utility model relates to a construction field especially relates to a regional support frame of stair is with wearing formula pole setting collet down.

Background

The stair position of building has all designed half floor height department of each floor and has had rest platform to the stair tread is the swash plate, all has the difficulty that the support frame was vertically set up when setting up the support frame. Because the frame body of the large non-stair part is erected at the bottom of the upper-layer structure at one time, the stair part is also installed with the large support and the template at the stair part for the convenience of construction in the construction site, and meanwhile, the rest platform floor slabs and the step slabs of the upper layer and the lower layer are constructed. The method generally adopted at present is to arrange a concrete test block with the same thickness as the platform plate at the bottom of an upright stanchion at a rest platform, and the upright stanchion is directly erected on a platform template or is provided with a reinforcement supporting base shaped like a Chinese character 'tu'. The methods have the safety risk that the vertical rods are not aligned to form a double-layer structure and simultaneously support the formwork, and the force for supporting the vertical rods to be directly transmitted to the base is directly transmitted to the formwork, so that great potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a regional support frame of stair is with wearing formula pole setting collet down to prior art not enough.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides an regional support frame of stair is with wearing formula pole setting collet down, includes a plurality of bases of being connected with the support frame pole setting, every the below of base all is provided with the lead screw, the lead screw passes the floor and cup joints the plastic sleeve at the position that passes the floor, still includes the top and holds in the palm, the top holds in the palm the setting in the below of floor, and the top that holds in the palm in the top is seted up the joint that supplies lead screw threaded connection.

Preferably, the top of the jacking is elongated to the bottom of the floor.

Preferably, a sweeping rod with a full length is transversely connected between the adjacent bases and used for connecting the bases into a whole.

Preferably, the elevation of the base is 30 to 50mm higher than the height of a floor.

Preferably, the height of the plastic sleeve is 20 to 30mm higher than the floor.

Compared with the prior art, the beneficial effects of the utility model are that: through the utility model discloses set up the stair template, can effectively save time and cost of labor, the installation is succinct convenient with the dismantlement process, and the security obtains showing to promote and reduces unexpected injury, and building quality further promotes the later stage and repairs the cost and reduce, and time, manual work, material, mechanical cost obtain effective control, and wear formula pole setting collet can reuse down, has further reduced material cost.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

FIG. 1 is a schematic view of a bottom-penetrating vertical rod bottom support;

fig. 2 is a using state diagram of the bottom-through type vertical rod bottom support.

In the figure: 1. the device comprises a base, 2, a screw rod, 3, a plastic sleeve, 4, a jacking and 5, and a floor sweeping rod.

Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.

Referring to fig. 1 and 2, a downward-penetrating type vertical rod bottom support for a support frame in a stair area comprises a plurality of bases 1 connected with a vertical rod of the support frame, a screw rod 2 is arranged below each base 1, the screw rod 2 penetrates through a floor slab and is sleeved with a plastic sleeve 3 at a position penetrating through the floor slab, the plastic sleeve 3 is used for isolating the screw rod 2 from concrete of the floor slab so as to be detached and circulated for use at a later period, the bottom support 4 is arranged below the floor slab, and a connector for connecting the screw rod 2 through threads is arranged at the top of the bottom support 4.

In order to reduce the length of the through-floor screw rod 2 and thus reduce the slenderness ratio of the screw rod 2 to improve the stability of the through-floor screw rod 2, the top of the next layer of jacking 4 is extended to the bottom of the plate. The specific operation is as follows: when a rest platform or a stair section inclined plate of a stair is constructed, a screw rod 2 with a plastic sleeve 3 is installed according to a hole reserved in the position of a through floor screw rod 2 on a next layer of template, and after the screw rod 2 is screwed with a top support 4 of the next layer, a support frame of the stair component on the layer is erected.

In order to improve the stability of the bases 1, a sweeping rod 5 which is long is transversely connected between the adjacent bases 1 and used for drawing each base 1 into a whole.

In addition, the elevation of the base 1 is 30 to 50mm higher than the floor height so as to facilitate concrete vibration and light collection, the corresponding plastic sleeve 3 is 20 to 30mm higher than the floor height, the concrete is prevented from flowing into the plastic sleeve 3 to influence later-stage screw rod 2 removal, after the concrete reaches the strength and a stair frame body is dismantled, a hole of a through floor is chiseled, the bottom is plugged by a foaming agent, and the upper portion is plugged by mortar.

Through the utility model discloses set up the stair template, can effectively save time and cost of labor, the installation is succinct convenient with the dismantlement process, and the security obtains showing to promote and reduces unexpected injury, and building quality further promotes the later stage and repairs the cost and reduce, and time, manual work, material, mechanical cost obtain effective control, just the utility model discloses can reuse, further reduce material cost, the stair support frame sets up the risk and reduces, sets up the support effect improvement of quality and support frame, has also stopped current construction method impression poor, has returned quality problems such as rust with exposed muscle.

As above, while the invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limiting the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
