Description

Small hollow block wall horizontal mortar joint plastering device

technical field

The utility model relates to a small-sized horizontal ash spreader for hollow block walls. the

Background technique

Small hollow block walls are currently widely used in masonry between reinforced concrete frames. During the masonry process, laying ash, that is, laying mortar is the dominant project. In the past, the method of using a large shovel to place ash multiple times to complete each small hollow block The solid part of the bottom surface is 25mm wide, 1100mm long, and 10mm thick horizontal mortar joints. The disadvantage is that there are as many as 16 ash spreading actions, and the ash spreading time is as long as ten seconds. It is easy to fatigue, and the width is uneven, which wastes mortar. The mortar is full The density is low and the horizontality of the blocks is not easy to control, which also increases the self-weight of the wall and reduces the thermal insulation capacity of the external wall, and the cost is high. The utility model uses a small-sized hollow block wall horizontal ash spreader for spreading ash, which can take advantage of the advantages and make up for the disadvantages, and the effect is remarkable. the

Accordingly, a new type of small-sized hollow block wall horizontal mortar joint plastering device can be produced for use on the construction site. the

Detailed ways

The specific implementation requirements of the utility model small-scale hollow block wall horizontal ash spreader are as follows:

⑴Each small hollow block wall horizontal ash spreader is composed of ash holding trough plate, vertical and horizontal ribs, connecting body, retaining shaft and handle. The small hollow block wall horizontal mortar joint plastering device is according to the size of Figure 1-4, and adopts the method of factory production to carry out batch processing and production in the factory and provide it to the construction site. The general plastic products factory can have this production capacity.

⑵During construction, the ash spread in the small hollow block masonry can be spread with a small hollow block wall horizontal ash spreader (hereinafter referred to as ash spreader). The operation method is: hold the ash spreader in the left hand with the bottom facing upwards, use a flat-headed ash shovel in the right hand to shovel a shovel of mortar in the ash bucket and buckle it to the ash spreader, and spread the mortar along the mortar ash storage tank for a circle and fill the middle with mortar. Scrape the ash trough once full, scrape out the remaining mortar and throw it into the ash bucket, according to the positional relationship between the center of the ash trough plate of the ash spreader and the center of each small hollow block in the horizontal ash joint, turn around and clamp the shaft of the ash spreader On the outer edge of the right-hand side of the small hollow block, turn over to the left-hand side to buckle the mortar on the small hollow block and lift the ash spreader, so far the ash spread process is completed. Afterwards, take a small hollow block and lay it down in the correct position according to the method of staggered joints and laying it down. Each small hollow block is pressed on the half of the length of the front and back two dustings. Under the action, the thickness of the mortar will be reduced by about 0.5mm, and finally the specified thickness of 10mm will be retained, and the fullness of the mortar will reach [(290×2×20.5+190×2×20.5+140×25)/(290×2× 25+190×2×25+140×25)=23180/27500=84.3%≥80%, which meets the requirements of relevant specifications, and the remaining 15.7% will be made up when the wall is plastered. When the small hollow block is prefabricated, the lower rib width is increased by about 25mm toward the inner side, and the bottom face is upward during masonry, so the size of the ash-bearing surface is sufficient, but the outer side is vertical. Since the mortar has a certain slump angle, the lower part of the upper block The outer sides of the two ribs along the length cannot touch the mortar, so the fullness of 84.3% is close to the maximum value. Even considering the influence of block dislocation and other factors, it is easy to reach 80% in the end. Compared with the previous large shovel point ash method, due to factors such as uneven ash spreading, it is difficult to reach the standard of 80% for the fullness of the ash spread, and the fullness of the mortar is an important indicator of the masonry quality. Tie reinforcement is usually installed between the frame column and the wall. The reinforcement is set in the mortar joint of the block. In the section with the tie reinforcement, it is advisable to add a shovel of mortar to cover the reinforcement tightly to play a protective role. Increase the durability of steel bars.
