Description

A kind of prefabricated multi-faceted connected monomer and masonry wall frame and its assembly method

Technical field

The invention specifically relates to a prefabricated multi-faceted connected unit and masonry wall frame and its assembly method.

Background technique

The development of prefabricated buildings is crucial to promoting the process of construction industrialization. At present, the development technology of prefabricated horizontal components (such as floors and beams) is becoming more and more perfect, while the development of prefabricated vertical components (exterior walls) is slow and relatively traditional. Cast-in-place technology and prefabricated exterior walls are expensive and have no market application prospects. Its cost disadvantages are mainly due to the following reasons:

The existing prefabricated assembly adopts the overall pouring process of the exterior wall, which requires expensive large steel molds, and different building designs require different types of large steel molds, resulting in huge investment costs;

When pouring the entire exterior wall, the prefabricated components occupy a large area, and the prefabricated components require long-term maintenance to improve their strength. This makes the preparation of prefabricated components long, the product turnover rate is low, and the turnover cost is increased. However, standing mold pouring is used , although it can alleviate the problem of low turnover rate due to the large floor area, but due to the large vertical height, the concrete is significantly affected by gravity during the pouring process, which can easily cause large differences in strength and elastic modulus between the upper and lower wall panels;

Due to the large size of the entire exterior wall, the number of components needs to be limited during transportation, and additional component safety protection measures must be added to prevent wall panels from cracking and falling off. This seriously affects the transportation efficiency and adds additional costs;

At present, the entire exterior wall is connected on-site using grouting sleeve connection (because grouting sleeve connection is relatively safe and the quality is relatively stable). However, grouting sleeve connection requires extremely high manufacturing and assembly accuracy of the exterior wall, which is currently impossible to achieve. Due to the precision requirements of smart assembly, the steel bars of the prefabricated exterior walls can only be assembled manually on-site by bending them, which results in an extension of the construction period, and grouting requires pressurized construction to ensure grouting quality, all of which increase costs.

In response to the above problems, although there is currently a solution to reduce costs by "standardizing the size of building exterior walls, and when the exterior walls of this size are used in sufficient quantities, it will form a cost advantage." However, the general performance of the actual operation is lacking. The architectural design pursues a variety of styles, which is in conflict with the standardized component sizes. There are no relevant structural components and processing methods to resolve the contradiction between the two. Standardized component sizes cannot be used because they can gain cost advantages. All buildings are constructed in the same style, which contradicts the essential concept of architecture, so standardized component sizes are not feasible based on existing prefabricated facade technology.

In view of the contradiction between the standardization of prefabricated exterior walls and the diversity of buildings, the high cost problems caused by low turnover and transportation assembly efficiency, and high assembly accuracy requirements, currently, masonry structures mostly use manual masonry methods, and the efficiency and construction quality are uneven, and As labor costs rise, the low-cost advantage of masonry exterior walls gradually decreases.

The existing masonry construction uses a mortar layer applied between prefabricated blocks. Since the elastic modulus and strength of the mortar are significantly different from those of prefabricated multi-faceted connection units, higher requirements are placed on the uniformity of the mortar layer thickness. Engineering practice and experimental research have shown that the greater the thickness of the mortar layer, the worse the uniformity of the mortar layer, which can easily cause uneven settlement and then cause cracking problems. For this reason, machine coating, that is, 3D printing mortar layer, was proposed to reduce the thickness of the mortar layer. Practice has shown that although 3D printing can reduce the thickness of the mortar layer, the uniformity of the mortar layer is significantly different, especially the mortar layer at the beginning and end of spraying, which can easily lead to problems of less or more material, which in turn affects the quality between layers. Uniformity; and 3D printing has higher quality requirements for mortar, which will further increase costs.

An assembly method using the masonry wall frame described in Specific Modes 1, 2 or 3. The assembly method is to equally divide a plurality of prefabricated multi-faceted connection units into four layers of transverse multi-faceted connection structures;

First, the first layer of transverse multi-faceted connection structure is overlapped as the underlying structure. One of the two prefabricated multi-faceted connection units at laterally adjacent positions in the transverse multi-facet connection structure of this layer passes through the first clamping part. Plug and match with the second snap-in part of another prefabricated multi-faceted connection unit. After the plug-in is completed, inject into each of the two long slots and short slots on the top surface of the first layer of transverse multi-faceted connection structure. Use a predetermined height of bonding mortar to ensure that the height from the injection surface of the bonding mortar to the top of the long slot and/or short slot is two-thirds of the total height of the slot, and then build it on the first layer of the transverse multi-faceted connection structure. Connected to the second layer of transverse multi-faceted connection structure, each long convex rib in the second layer of transverse multi-faceted connection structure is embedded and bonded in its corresponding long slot, and each short convex rib is embedded and bonded in its corresponding short slot.

Body, in each layer of the four-layer transverse multi-faceted connection structure, multiple transverse through-cavities are connected laterally to form a long transverse through-cavity, and thin steel wires or thin fiber bundles are straightened in the vertical through-cavity And apply prestressed force, and then pour polyurethane or quick-hardening bonding material into the vertical through cavity to form a prestressed wall frame;

Then, the prestressed wall frame is transported to the construction site. After the hoisting is completed, the longitudinal steel bars are inserted into the longitudinal through long cavities of the prestressed wall frame through the robotic arm. According to the structural design requirements, each longitudinal through long cavity is penetrated.

1. The masonry wall frame structure formed by transverse and longitudinal overlapping of multiple prefabricated multi-faceted connecting units of the present invention solves four contradictory points, which are:

First: Prefabricated exterior walls need to standardize exterior wall dimensions to reduce costs. Because of the high price of steel molds, unified standardization has not been popularized. Too many steel molds need to be produced, which has no market advantage. However, structural design must serve architectural design. Architectural design is full of art and diverse, and it is difficult to meet the diverse actual construction needs of buildings. In contrast, the masonry construction of the present invention can ensure high efficiency, small floor space, and low floor space requirements.

Second: the present invention eliminates the mortar layer of the masonry structure, forming a structural form without visible mortar on the outer wall.

Third: Due to the first multi-directional limiter, the second multi-directional limiter and the third multi-directional limiter, the transverse steel bars and the longitudinal steel bars can be assembled according to the corresponding predetermined positions, and it can also ensure that each steel bar is aligned with the predetermined position. Each horizontal and vertical through-cavity is effectively separated, eliminating the need to add additional steps to make a steel cage; a cavity is formed inside the wall through prefabricated hollow-core masonry and overlapping masonry, and then the reinforcing grouting process is used to form the whole. The entire process can be operated by machines, with high construction efficiency and strong wall integrity. Under the prefabricated process, the goal of "prefabrication equals cast-in-place" can be achieved, which not only achieves the high-efficiency and pollution-free industrialization goals of prefabricated assembly, but also solves the problem. It overcomes the shortcomings of poor overall stability of prefabricated assembly.

The present invention is suitable for a prefabricated masonry wall frame structure and assembly method for intelligent construction. Non-load-bearing walls, load-bearing walls and shear walls can be prepared according to engineering requirements, which solves the existing contradictions and greatly reduces costs. The cast-in-place system has obvious cost advantages and broad market application prospects.

The invention includes prestressed masonry hollow frame technology and reinforcing grouting assembly technology. This technology can be used to build and splice prefabricated multi-faceted connected units according to different architectural styles, and utilize prefabricated multi-faceted connected units to achieve construction requirements. It can meet the needs of building diversity at a lower cost; in addition, it also solves the problem of prefabrication The process occupies a large area, the uneven mortar layer leads to instability, the arrangement of steel bars is cumbersome, the integrity of the wall is poor, and the wall cracks during transportation.
