Description

A New Tool-type Dustpan Formwork for Improving the Forming Quality of Concrete at the Top of Structural Columns

technical field

The utility model relates to the technical field of building engineering formwork, in particular to a novel tool-type dustpan formwork for improving the quality of concrete forming at the top of a construction column.

Background technique

In the current structural column formwork construction technology, the top of the structural column is treated with a dustpan formwork, and the concrete at the mouth of the dustpan is removed after the concrete pouring of the structural column is completed. This method can achieve the compactness of the concrete at the top of the structural column, but the cost of labor and materials is relatively large, and the vibration during chiseling also causes a kind of damage to the wall. Another method is to treat the concrete at the top of the structural column by secondary filling with dry hard concrete or mortar. This method is prone to quality defects such as leaking reinforcement and honeycomb pitting, which will adversely affect the overall seismic performance of the structural column.

Utility model content

The purpose of this utility model is to aim at the defects and deficiencies of the prior art, and provide a new tool-type dustpan formwork for improving the quality of the concrete forming at the top of the structural column. It has a simple structure and a reasonable design. The low-cost tool-type construction column dustpan formwork is used to construct the concrete at the top of the construction column, which solves the problems of quality defects such as uncompacted concrete at the top of the construction column and secondary filling, and improves the quality of the one-time pouring and molding of the top concrete.

In order to achieve the above purpose, the technical solution adopted by the utility model is: it includes a dustpan template, a latch, a guide groove, a movable support, and a plug-in steel plate; It is fixed at the bottom of the dustpan formwork and is used to block the gap between the dustpan formwork and the construction column; one end of the movable support is provided with a hinge, and the movable support is movably connected to the middle of the bottom plate of the dustpan formwork through the hinge, and the plug-in steel plate is set At the dustpan mouth of the dustpan template, the bottom slide is arranged on the guide groove, and can be knocked and moved along the direction of the guide groove.

The bolt is a screw with a diameter of 12-14mm, which can be rotatably inserted into the two side plates of the dustpan formwork and the main keel on both sides of the construction column.

The front end of the plug-in steel plate has a slope angle of 45-60 degrees, which is convenient for inserting into concrete; the rear end is provided with angle steel, which is convenient for hammering into concrete.

The installation steps of the utility model are:

1. After the installation of the lower formwork of the structural column is completed, fix the dustpan formwork to the keels on both sides of the lower formwork through bolts;

2. Fix the guide groove at the bottom of the dustpan template and block the gap;

3. The bottom end of the movable support is fixed to the lower keel of the lower formwork;

4. After the structural column is completely filled with concrete, gently tap the plug-in steel plate into place from one side of the keel with a small hammer until it completely enters the other side of the keel.

After the plug-in steel plate is completely installed, the bolt can be rotated and removed, and the dustpan template and movable support can be removed and applied to the pouring of other structural columns.

After adopting the above-mentioned structure, the utility model has the beneficial effects as follows: it solves the problems of quality defects such as uncompacted concrete at the top of the structural column and secondary filling, and improves the quality of one-time pouring and molding of the top concrete; it is economical and practical, and can be applied to other buildings after the dustpan is removed. It can be reused on the construction column, which saves the time for processing and installing the dustpan formwork for each construction column.

Detailed ways

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

See as shown in Figure 1, the technical scheme that this specific embodiment adopts is: it comprises dustpan template 1, latch 2, guide groove 3, movable support 4, plug-in steel plate 5; Two bolts 2 are inserted, and the guide groove 3 is fixed on the bottom of the dustpan formwork 1, which is used to block the gap between the dustpan formwork 1 and the construction column; one end of the movable support 4 is provided with a hinge 4-1. The support 4 is movably connected with the middle part of the bottom plate of the dustpan template 1 through the hinge 4-1, the plug-in steel plate 5 is set at the dustpan mouth of the dustpan template 1, and the bottom slides on the guide groove 3, and can be knocked along the direction of the guide groove 3 move.

The bolt 2 is a screw with a diameter of 12-14mm, which can be rotatably inserted into the side plates on both sides of the dustpan template 1 and the main keel on both sides of the construction column.

The front end of the plug-in steel plate 5 has a slope angle of 45-60 degrees, which is convenient for inserting into concrete; the rear end is provided with an angle steel 5-1, which is convenient for hammering into concrete.

The installation steps of this embodiment are:

1. After the installation of the lower formwork of the structural column is completed, fix the dustpan formwork 1 to the keels on both sides of the lower formwork through the bolt 2;

2. Fix the guide groove 3 on the bottom of the dustpan template 1 and plug the gap;
