Abstract
A reinforcing device for a combined steel formwork belongs to the technical field of building construction and comprises a steel formwork and a reinforcing part. The reinforcing device is characterized in that the reinforcing part consists of an opposite-pulling bolt (2) and a steel plate (1) which are welded together, and the reinforcing part is connected with the steel formwork (5) by the aid of a U-shaped clamp. The reinforcing part is made of full steel by means of welding, after a hole on the steel plate (1) and a central line of the opposite-pulling bolt (2) meet requirements, the steel plate (1) is welded with the opposite-pulling bolt (2), the height of a weld joint is not lower than 5mm, and finally, the reinforcing part is connected with the steel formwork (5) by the aid of the U-shaped clamp. The reinforcing device has the advantages that the reinforcing device can be processed and manufactured on a construction site, can meet urgent needs of engineering, shortens construction period, and reduces engineering cost.
Description
Technical field
The utility model belongs to technical field of building construction, particularly relates to a kind of bracing means of combined steel formwork, is applicable to the device in the cast-in-place concrete structure construction.
Background technology
In building structural element construction,, particularly important to improving workmanship, accelerating construction progress, reduction engineering cost because therefore the used form work engineering cost height of cast-in-situ concrete, adopts advanced formwork reinforcement technology.The template installation requirement is very tight, and the conventional way of formwork reinforcement is to punch on steel form, wears split bolt and reinforces, and not only steel form is damaged, and needs perforations adding after the use, wastes time and energy.Now change at split bolt two ends weldering pull-tab, by practice, the presentation quality of cast-in-place concrete structure can both meet design requirement.This reinforcement means can play the control template inside dimension simultaneously and prevent the rise effect of mould two aspects of concrete, and is promptly convenient, fast, saves fund again.
Summary of the invention
The purpose of this utility model is, a kind of bracing means of combined steel formwork is provided, and overcomes the high deficiency of operating expenses in the past, not only can satisfy the workmanship requirement, and can reduce engineering cost.
The utility model comprises steel form, girth member; Girth member is made up of split bolt and sheet steel, is welding between split bolt and the sheet steel, is to be connected with U-shaped card (be used for the adjacent steel template and add the supporting clamp that fastens) between girth member and the steel form.On sheet steel, finish earlier the center line of U-shaped card, punching, and then welding split bolt, split bolt and sheet steel double welding, weld bead height is not less than 5mm, and double welded joint length is not less than 35mm.
Horizontal stupefied and upright stupefied Φ 48 * 3.5 steel pipes that all adopt of steel form both sides, the connected mode of steel pipe and steel form is colligation.
The utility model girth member can be processed according to the split bolt quantity that template strength calculates, at any time adjust processing progress according to field demand, reduce the operation of template punching and perforations adding, split bolt two ends threading, promptly shorten the cycle, reduce processing cost again.
The beneficial effects of the utility model are after steel form adopts girth member, and convenient construction is saved engineering cost.

Fig. 2 is the sectional drawing of the chief component of the utility model girth member.Wherein, the hole 3 of sheet steel 1, split bolt 2, U-shaped card.
Fig. 3 is the utility model steel form and girth member scheme of installation.Wherein, sheet steel 1, split bolt 2, U-shaped card 4, steel form 5, horizontal stupefied 6, upright stupefied 7.
The specific embodiment
Fig. 1～Fig. 2 is a kind of specific embodiment of the present utility model.
The utility model comprises steel form, girth member; Girth member is made up of split bolt 2 and sheet steel 1, is welding between split bolt 2 and the sheet steel 1, is to use the U-shaped card connection between girth member and the steel form 5.
On sheet steel 1, finish earlier the center line of U-shaped card, punching, and then welding split bolt 2, split bolt 2 and sheet steel 1 double welding, weld bead height is not less than 5mm, and double welded joint length is not less than 35mm.
In Fig. 1, the distance between sheet steel 1 and the split bolt 2 55～60mm that will stagger, two holes adds steel form thickness for wall thickness, and the hole 3 of U-shaped card is the hole with power auger.
In Fig. 2, being connected between sheet steel 1 and the split bolt 2 is welding.
In Fig. 3, be to use the U-shaped card connection between steel form 5 and the sheet steel 1, being connected between the steel form 5 and horizontal stupefied 6 is colligation, being connected between horizontal stupefied 6 and upright stupefied 7 is colligation.
The key of steel form girth member processing is the welding of sheet steel and the location of split bolt.Before the sheet steel perforate, eject centre of location line earlier, carry out perforate with machinery again, with grinding machine the sheet steel bottom is polished flat after the perforate.The centre of location line of the good split bolt of bullet must guarantee that two sheet steel in same plane, guarantee that the split bolt position is accurate.
