Description

A placing machine pouring system and pouring method for concrete in prefabricated building construction

Technical field

The invention belongs to the field of building construction, and mainly relates to a placing machine pouring system and a pouring method for concrete in prefabricated building construction.

Background technique

In recent years, prefabricated construction projects have gradually developed, and PC composite board components are the most important components of prefabricated buildings. They have a large installation area, and a single composite board itself has the characteristics of large plane size and small thickness. During construction It is especially important to take protective measures to prevent laminates from cracking.

Traditional non-fabricated construction construction placing machines are placed directly on the beams or slab steel bars of the cast-in-place floor slabs, and reinforcement measures are taken on the bottom of the formwork at the corresponding positions. However, in prefabricated construction projects, when the laminated panels are installed and the concrete is poured after the laminated panels are poured, the laminated panels The slab cannot directly bear the load of the placing machine's legs. Therefore, the placing machine was not used when pouring concrete. Instead, pipes were used to move concrete pumps on the slab. This resulted in low construction efficiency and also affected the installation quality of the laminated slabs.

Therefore, there is an urgent need to invent a new placing machine system and pouring method for prefabricated building concrete pouring construction, which can solve the problem of placing concrete on laminated slabs and make the installation and fixing of the base of the placing machine simple, safe and reliable.

Contents of the invention

The object of the present invention is to provide a concrete pouring method for prefabricated building construction in view of the above-mentioned problems, to reduce the damage to the laminated plates caused by the vibration of the distribution machine during the spreading process, and to prevent the laminated plates from being dislocated in the installation position due to vibrations. This will affect the quality of subsequent projects and prevent the moving position of the cloth machine.

The technical solution of the present invention is as follows:

A method for pouring concrete in prefabricated buildings using a placing machine, including the following steps:

S1. On the floor of the prefabricated building, pouring is carried out layer by layer from bottom to top. Construction openings are opened at the same position of the working floor and the lower floor that need to be poured. The steel bars on the four sides of the opening are left as construction joints. The traditional The stand of the spreading machine is increased and extended, and a crane is used to place the spreading machine on the lower floor through the reserved hole on the working floor;

S2. Set an installation base with a template at the reserved hole on the lower floor floor 16, fit the template under the reserved hole, and use the installation base to install and fix the distributor 1 and the template;

S3. The placing machine completes pouring concrete on the pouring floor;

S4. After the pouring is completed, the distribution machine stand and installation base are dismantled and separated. The tower crane lifts the distribution machine away from the working point. At the same time, the formwork and steel bars of the reserved holes on the lower floor slab are restored and tied, and the concrete on the working layer is used to pour the lower floor slab. Reserve holes for sealing.

In this way, construction is carried out layer by layer. When constructing the next layer of slab concrete, the reserved openings of this layer are poured and sealed. Since the construction is carried out layer by layer upward, there will be no damage to the floor below.

In step S1, the floor opening matches the size of the distribution machine's stand. The size of the floor opening should not be too large compared with the distribution machine. The distribution machine can be limited to prevent movement. On the other hand, the distribution machine can be reduced in size. The subsequent cost of sealing the hole.

Furthermore, when the working floor is the second floor, there is no need to open holes and seal the ground on the first floor, and the installation base without formwork is directly used to fix the distribution machine.

Fitting the formwork below the opening on the lower floor is beneficial to subsequent sealing construction. At the same time, a fixing frame is set below the opening to be fixed with the installation frame on the floor. The back-pull support is used to further increase the stability of the cloth machine and reduce the During the pouring construction, the dynamic load will cause vibrations to the working layer and the reserved openings in the lower layer. A cylinder is installed on the outside of the connecting rod at the opening of the lower floor so that the opening will not affect the connecting rod during the subsequent pouring and sealing process and facilitates the disassembly of the connecting rod.

Further, the horizontal mounting frame is I-beam, the vertical mounting frame is channel steel, the fixing frame is channel steel, and the connecting rod is round steel with threads at the upper and lower ends, from top to bottom. Use the connecting rod to pass through the vertical mounting frame, the horizontal mounting frame, the reserved hole in the floor surface, the template, and the fixed frame in sequence. The upper surface of the vertical mounting frame and the lower surface of the fixed frame are fastened with nuts. Using the vertical mounting frame to press the horizontal mounting frame can improve the stability of the installation base; using round steel to penetrate the detachable connection can achieve rapid assembly and disassembly of the cloth device to improve engineering efficiency.

Further, the four corners of the transverse mounting frame of the installation base are respectively provided with latch seats, and the four corners of the bottom of the stand of the cloth machine are equipped with latch sleeves corresponding to the positions of the latch blocks. The pins are inserted into the latch blocks and the latch blocks. The installation base is connected and fixed with the cloth machine in the set. The latching method can be used to quickly fix the cloth machine and the installation base. Compared with lateral fixation, latch fixation can effectively avoid lateral displacement of the cloth machine on the installation base.

Further, vibration-absorbing devices are provided at the bottoms of both ends of the transverse mounting frame. The vibration-absorbing devices are elastic bases to further dampen the vibration of the cloth machine.

Further, a bracket seat is provided around the frame body of the upright frame of the distribution machine, and a bracket is fixedly installed on the bracket seat.

Further, screw holes are provided on the bracket base and the bracket and are fixed by bolts.

Furthermore, the bottom of the bracket is covered with an anti-slip cover to further improve the stability of the support.

Furthermore, the stand height of the distributor is between 1.5 and 2 times the height of a single floor, which is conducive to the work of construction workers.

In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: the concrete placing machine system used in prefabricated buildings of the present invention separates the placing system of the placing machine from the pouring operation layer support system and places it on the operation layer. On the lower floor slab, the pumping impact of pouring concrete is carried by the next floor slab, ensuring that the laminated plates on the working floor will not be displaced or damaged, causing quality and safety problems; the previous method of directly moving the pump pipes to distribute materials has been changed, improving The construction efficiency is improved; the quickly fixed installation base is used to realize the rapid and stable installation of the cloth machine and the installation base, and a reinforcement system is added to reinforce and dampen the installation base to ensure safe and reliable construction; in the present invention, the formwork is added to Install it in the base to facilitate subsequent sealing of the reserved holes.
