Formwork frame for cast-in-place concrete without scaffolding

Abstract

The invention discloses a template frame capable of realizing no-scaffold cast-in-situ concrete. The template frame comprises two main beams, as well as a plurality of horizontal support rods and a plurality of secondary beams, which are arranged between the two main beams, wherein supporting bars are arranged on the main beams; the two supporting bars are used for supporting different ends of the horizontal support rods and the secondary beams; different ends of the horizontal support rods are in bolted connection with the different supporting bars through different connecting bolts; different ends of the secondary beams are placed on the different supporting bars; the secondary beams are made of a material allowing fastening nails to be screwed and / or driven therein. The template frame provided by the scheme can replace a conventional all-round scaffold to solve the problems that the erecting workload of the template frame is heavy, the template transfer workload is heavy, and many risk points exist on the template frame.

Description

technical field

[0001] The invention relates to the technical field of jacking equipment, in particular to a formwork frame capable of realizing cast-in-place concrete without a scaffold. Background technique

[0002] Cast-in-place concrete is a form of floor slab that has been widely used in recent years. The social and economic benefits of the obtained cast-in-place concrete hollow floor in modern buildings are very obvious. It is different from the previous prefabricated slab. The floor has the following advantages: 1. It can reduce the height of the floor: there is no need to set beams under the floor, and the space occupied by the beams is saved. Taking the 10th floor as an example, it can save 4.5 to 7.0 meters; 2. Save decoration costs: the floor slab There is no beam edge, which reduces the plastering on the beam and improves the interior decoration effect; 3. Reduce the formwork investment: there is no beam under the floor, and there is no need to use a special form...

Embodiment 1

[0028] Such as figure 1 As shown, the formwork frame of cast-in-place concrete without scaffolding can be realized, including two main beams 1 and a plurality of horizontal support rods 8 and a plurality of secondary beams 9 arranged between the two main beams 1. Both support bars 2 are provided, and the two support bars 2 are used to provide support for different ends of the horizontal support bar 8 and the secondary beam 9;

[0029] The different ends of the horizontal support bar 8 are all bolted to different support bars 2 through different connecting bolts 7;

[0030] Different ends of the secondary beam 9 rest on different support bars 2 , and the secondary beam 9 is a material that can be screwed in and / or driven into the fastening nail 10 .

[0031] Specifically, this formwork frame is especially suitable for the steel structure frame erected by H-shaped steel 3 whose web is in the vertical direction, that is, the main girder provided by the basic plan is respectively f...

Embodiment 2

[0035] Such as figure 1 As shown, the present embodiment is further limited on the basis of Embodiment 1: in order to make each horizontal support bar 8 all play a good role in supporting the template 6, and each secondary beam 9 all play a good role in fixing the template 6, the horizontal support The rods 8 and the secondary beams 9 are arranged along the length direction of the support bar 2 , and the horizontal support rods 8 and the secondary beams 9 are evenly spaced. According to the specific application, such as the specific weight of cast-in-place concrete, one or more secondary beams 9 and two adjacent secondary beams 9 can be arranged between two adjacent horizontal support rods 8 according to the specific application. The form of a plurality of horizontal support rods 8 is set between.

[0036] In order to facilitate the positioning of the main beam 1 in the lengthwise direction of the H-shaped steel 3 , gaps 5 are provided on the upper and lower sides of both end...

Embodiment 3

[0043] Such as figure 1 As shown, this embodiment is further limited on the basis of any one of the technical solutions provided by any one of the above embodiments: as a form of realization of the secondary beam 9 that is convenient for ordinary iron nails or screws to be embedded, the material of the secondary beam 9 is timber. The secondary beam 9 made of wood is not only easy to insert the fastening nails 10, but also has high connection strength between the fastening nails 10 and the secondary beam 9, and meanwhile, the secondary beam 9 in this form can be recycled many times.

[0044] In order to enable the formwork 6 to be installed on the formwork frame evenly, and at the same time enable the secondary beam 9 to exert a certain bearing capacity, the upper surfaces of the horizontal support rod 8 and the secondary beam 9 are all located on the same plane.
