Abstract

The utility model discloses a formwork for horizontal construction joints of floor slabs. The width and height of the grooves are the steel bar diameter plus 2mm, and the distance between two adjacent grooves is the steel bar spacing. The utility model has the advantages of simple manufacture, convenient construction, can be used repeatedly, is not easy to leak slurry, and reduces the cost.

Description

A formwork for horizontal construction joints of floor slabs

technical field

The utility model relates to a formwork, in particular to a formwork used for horizontal construction joints of floor slabs.

Background technique

With the expansion of the building scale, the area of a single layer is getting larger and larger. In order to prevent the occurrence of temperature cracks, post-pouring belts are often set up. The support is particularly important, but at present, steel mesh and wooden squares are usually used for setting, resulting in slurry leakage, waste of materials, and poor visual quality, resulting in the phenomenon of chipping after the event.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a formwork for horizontal construction joints of floor slabs that does not cause grout leakage, reduces costs, has good visual quality, and does not cause subsequent chiseling.

The utility model relates to a formwork used for horizontal construction joints of floor slabs. The width and height of the grooves mentioned above are the steel bar diameter plus 2mm, and the distance between two adjacent grooves is the steel bar spacing.

The utility model has the advantages of simple manufacture, convenient construction, can be used repeatedly, is not easy to leak slurry, and reduces the cost.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail.

As shown in the accompanying drawings, a formwork for horizontal construction joints of floor slabs of the present utility model includes a formwork 1, and a plurality of grooves are opened at the bottom of the formwork or grooves are opened at the top and bottom of the formwork. A plurality of grooves, the width and height of the grooves are the steel bar diameter plus 2mm, and the distance between two adjacent grooves is the steel bar spacing.

The method of using this structure is: for single-layer steel bars, as shown in Figure 3, install wooden strips at the bottom of the formwork, the steel bars are inserted into the bottom groove of the formwork, and the back is reinforced and fixed with short wooden boards and iron nails; for double-layer steel bars, As shown in Figure 4, wooden strips are installed on the bottom and top of the formwork, the upper and lower steel bars are inserted into the upper and lower grooves of the formwork, and the back is reinforced and fixed with short wooden boards and iron nails.

Claims (1)

1. template that is used for the floor horizontal construction joint, it comprises template, it is characterized in that: the bottom of described template has a plurality of grooves or all has a plurality of grooves in top and the bottom of described template, described recess width and highly be bar diameter and add 2mm, the spacing of two adjacent grooves is rebar spacing.
