Abstract

The utility model discloses a formwork for a concrete column, which belongs to building units. The formwork is an L-shaped plate formed from plate bodies (1, 2) that are intersected, a rib (3) is arranged on the upper end surface of the formwork, and a groove (3) matched with the rib (3) is arranged on the lower end surface of the formwork. The formwork is used for fabricating the concrete column by assembling on the periphery of colligated reinforcing steel bars from bottom to up and then pouring concrete into the hollow cavity of the formwork. The formwork needs not to be disassembled and can be used as the permanent surface of the concrete column.

Description

A kind of concrete column formwork

Technical field

The utility model relates to a kind of building unit, particularly a kind of formwork that is used to build the building concrete post.

Background technology

Present Building technology utilizes template to pour into a mould at the scene when the concrete column of construction of buildings mostly, and the cast rear pattern plate needs to remove, and with damaged surface out-of-flatness after the template, needs floating again.Operation is many, and speed of application is slow, takes a lot of work, requires great effort.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model need not removed after a kind of construction is provided, the surface does not need again floating and have the concrete column formwork of decoration functions concurrently, utilize the concrete column of its construction of buildings, can accelerate building speed greatly, and saving of labor, laborsaving.

The utility model is achieved by the following technical solution: a kind of concrete column formwork, its housing are L shape plate, are intersected by the two boards body to form, and the upper surface of housing has convex tendon, and its lower surface has the groove that adapts with described convex tendon.

The utility model can be prefabricated in factory.When utilizing the utility model to build concrete column, with the utility model assembly unit successively from the bottom to top, be connected with groove fit by convex tendon between the neighbouring formwork around according to the design reinforcing bar that colligation is good of concrete column.In the cavity that is formed by formwork, fluid concrete forms the concrete column of building after the assembly unit, and formwork need not removed, and it is as the permanent cylinder of concrete column.The convex tendon of working in coordination not only plays a part to be connected with groove, and when concreting, it also plays the effect that prevents that concrete from leaking outside.

To connect more firm and prevent that better concrete from leaking outside in order to make between formwork, the side end face of two boards body of the present utility model has convex tendon and the groove that adapts respectively, when the assembly unit formwork, is connected with groove fit by convex tendon between the adjacent formwork in the left and right sides.

For formwork is combined with concrete firmly, can also projection or groove be set at the housing medial surface of formwork, behind the fluid concrete, can form concavo-convex bonding surface between formwork and the concrete, can make formwork and concrete strong bonded.

Hull outside face of the present utility model can also be designed to have the surface of decoration functions, as the surface of band patterned surface or Fang Mountain stone etc., makes the concrete column external surface of construction have decorative effect.

The utility model is simple in structure, and is simple because of the formwork assembly unit when utilizing it to build concrete column, do not need after the construction to remove, and therefore can accelerate speed of application greatly; Secondly, the concrete column of construction not only external surface does not need replastering, and has decorative effect, can save construction investment.

The specific embodiment

Below in conjunction with accompanying drawing and non-limiting embodiment the utility model is further described:

Embodiment 1

Shown in accompanying

drawing

1,2, a kind of concrete column formwork, its housing are L shape plate, are intersected by plate body 1, plate body 2 to form, and the upper surface of housing has convex tendon 3, and its lower surface has the groove 4 that adapts with convex tendon 3.

The utility model can be prefabricated in factory, and the upright seam between the formwork is not on same straight line after the assembly unit in order to make, and the length of plate body 1, plate body 2 does not generally wait, and upright seam is staggered mutually.As shown in Figure 9, when utilizing the utility model to build concrete column, around the reinforcing bar that colligation is good,, be connected by convex tendon 3 and groove 4 between the neighbouring formwork formwork assembly unit successively from the bottom to top.After the assembly unit, fluid concrete in the cavity that forms by formwork, the concrete column of formation building, formwork need not removed as the permanent cylinder of concrete column.Being connected of convex tendon 3 and groove 4, concrete leaks outside in the junction in the time of also can preventing to pour into a mould.

For the external surface of the concrete column that makes construction has certain decorative effect, also the lateral surface of formwork can be designed to have the surface of decoration functions, as the surface of band patterned surface or Fang Mountain stone etc.

Embodiment 2

Shown in accompanying

drawing

3,4, a kind of concrete column formwork, its housing are L shape plate, by plate body 1, plate body 2 crossing forming, the upper surface of housing has convex tendon 3, and its lower surface has the groove 4 that adapts with convex tendon 3, and the side end face of plate body 1, plate body 2 has convex tendon 5 and the groove 6 that adapts respectively.In the present embodiment, being connected between the adjacent formwork can prevent that also the concrete of pouring into a mould from leaking outside simultaneously about when convex tendon 5 and groove 6 are used for assembly unit.

The formwork lateral surface of present embodiment also can with the embodiment 1 the same external surface made from decoration functions, its using method is identical with embodiment 1.

Embodiment 3

As accompanying drawing 5, shown in 6, a kind of concrete column formwork, its housing is a L shape plate, by plate body 1, plate body 2 crossing forming, the upper surface of housing has convex tendon 3, and its lower surface has the groove 4 that adapts with convex tendon 3, the side end face of plate body 1, plate body 2 has convex tendon 5 and the groove 6 that adapts respectively, and the inner surface of housing has at least one groove 7.

The lip-deep groove 7 of the formwork of present embodiment is behind fluid concrete, and the concavo-convex bonding surface of formation between the concrete, can increase the pull-out capacity between formwork and the concrete, and it is more firm that formwork is combined with concrete.

Make formwork combine firmly purpose with concrete in order to reach, the inner surface of housing can also be provided with at least one projection 8 separately, as shown in Figure 7, or be provided with simultaneously at least one the projection and at least one groove, as shown in Figure 8, behind fluid concrete, form concavo-convex bonding surface between described projection or groove and the concrete, it is more firm that formwork is combined with concrete.

The formwork lateral surface of present embodiment also can with the embodiment 1 the same external surface made from decoration functions, its using method is also identical with embodiment 1.

Above-mentioned listed embodiment is not to restriction of the present utility model only with the explanation of the present utility model of opposing, and those skilled in the art can also make a change on this basis.
