Description

A new type of fair-faced concrete large formwork connector device

technical field

The utility model relates to the field of building construction, in particular to a novel large formwork connector device for fair-faced concrete.

Background technique

Fair-faced concrete building is a building form that has just emerged in China in recent years. It often uses carefully designed and arranged open joints, Zen joints (that is, joints between templates) and the combination of tension bolt holes to form a natural state as a decorative surface. An important design method to show architectural aesthetics. It has high requirements on the quality of concrete structure construction perception, so designers often dare not try it lightly. According to the requirements of "Construction Technology Standards for Fair-faced Concrete" (China Construction Industry Press), which is widely used in China at present, the gap between the fair-faced concrete Zen joints (joints between the templates) is not more than 2mm, so the gap between the templates is the fair-faced concrete formwork It is one of the key and difficult points of construction quality control.

At present, steel-wood system formwork is mostly used in the construction of fair-faced concrete wall structures in China, and adjacent large formworks are connected and fixed with connecting fixtures. The connecting fixtures widely used now only have the function of ensuring the connection and locking of adjacent clear water wall formworks, and do not have the functions of ensuring the smooth splicing of adjacent large formworks and the adjustment and correction of formwork misalignment. Therefore, in the construction of fair-faced concrete structures, it is difficult to control the quality of formwork joint construction and inconvenient to operate.

Contents of utility models

The purpose of this utility model is to provide a new type of large formwork connector device for fair-faced concrete, which can ensure that the joints of large formworks of clear-faced concrete walls are spliced tightly and evenly, and the staggering control is within 2mm, so as to meet the structural perception requirements of clear-faced concrete walls.

The utility model includes a "T"-shaped connector and a fastening fixture, and also includes a flatness adjuster, and the flatness regulator is installed at 200mm above the "T"-shaped connector and the fastening fixture.

The "T"-shaped connecting piece includes a first angle steel, a second angle steel and a square steel sheet, and the first angle steel and the second angle steel are welded through the square steel sheet.

The fastening fixture includes a dish-shaped gasket, a wedge-shaped steel sheet and a clamp pull rod. A small square hole is chiseled on the clamp pull rod, and one end of the wedge-shaped steel sheet is snapped into the square small hole on the clamp pull rod. , and fix the dish washer on the clamp rod.

The flatness adjuster includes a lead screw and a clamp. A clamp nut is arranged below the clamp, and the screw rod is fixed on the clamp through the clamp nut.

Both the first angle steel and the second angle steel are angle steels with a length of 550 mm and a thickness of 5 mm.

The fastening jig is a steel casting made of stereotypes.

The flatness adjuster is a steel casting made of stereotypes.

Compared with the prior art, the beneficial effects of the utility model are:

1) The quality control effect of formwork seams and staggering is good, meeting the requirement of fair-faced concrete for formwork staggering not greater than 2mm;

2) Simple operation;

3) It can be used repeatedly to reduce costs;

4) It has strong versatility and can also be applied to the quality control of ordinary concrete structure formwork installation.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is the overall structure schematic diagram of the present utility model. "T"-shaped connector 1 includes first angle steel 4, second angle steel 5, square steel sheet 6, first angle steel 4 and second angle steel 5 are welded through square steel sheet 6; fastening fixture 2 includes dish-shaped gasket 7. Wedge-shaped steel sheet 8 and clamp rod 9. A small square hole is chiseled on the clamp rod 9. Insert one end of the wedge-shaped steel sheet 8 into the square hole on the clamp rod 9, and fix the dish gasket 7 on the On the clamp rod 9 ; the flatness adjuster 3 includes a lead screw 10 and a clamp 11 , and a clamp nut 12 is installed below the clamp 11 , and the lead screw 10 is fixed on the clamp 11 through the clamp nut 12 .

Fig. 2 is a schematic diagram of installation and use of the utility model, and the specific installation steps are:

1) The large formwork of the fair-faced concrete wall is hoisted in place, temporarily supported by steel pipes, and the "T"-shaped connector 1 shown in Figure 1 is tightly connected to the channel steel back of the large clear-faced concrete formwork.

2) Install the fastening clamp 2: the operator first uses the clamp rod 9 to tighten the "T"-shaped connector 1 and the channel steel back of the clear-water concrete large formwork, and then wears the dish-shaped gasket 7 on the clamp rod 9 Then insert the wedge-shaped steel sheet 8 into the square hole on the pull rod 9 of the fixture. By hitting the wedge-shaped steel sheet 8 with a hammer, the fastening fixture 9 can connect the "T"-shaped connector to the channel steel back of the large clear-water concrete formwork. The corrugated card is tight, and the adjacent large templates are connected into a whole.
