Description

A composite laminated board

technical field

The invention belongs to the technical field of prefabricated building boards, in particular to a prefabricated composite laminated board.

Background technique

Prefabricated buildings meet the requirements of building industrialization and green environmental protection, especially the industrial policy of green buildings and building industrialization in my country, and the demand for prefabricated buildings is increasing. Prefabricated wall panels and laminated floors are one of the main contents of prefabricated buildings. The existing prefabricated wall panels mainly include reinforced concrete wall panels and aerated concrete slabs, and the existing laminated floors are reinforced concrete single-material floors. Reinforced concrete wall panels and laminated floor slabs are heavy, poor thermal insulation performance, and high engineering cost; air-entrained concrete slabs are light in weight, but they need to be assembled on site, and the construction and material costs are relatively high.

The Chinese Patent Publication No. CN103056966A discloses a method for making prefabricated wall panels with finished blocks, which belongs to the field of construction. It is a pre-built masonry using block mortar. Its integrity and wind resistance are relatively poor, so it is difficult to apply into the exterior walls of high-rise buildings.

Chinese Patent Publication No. CN106351373A discloses a lattice prefabricated thermal insulation and sound insulation floor, which belongs to the technical field of building structure thermal insulation integration. Its main features are: 1. The upper and lower panels are installed at the same time; 2. The upper and lower panels are respectively provided with lattice ribs, and the lattice ribs of the upper and lower panels are not directly connected. The function of the lattice ribs should be to strengthen the rigidity and strength of the panels; 3. By setting lattice columns between the upper and lower panels to cooperate with the upper and lower panels to work at the same time; 4. The filling material between the upper and lower panels is used for thermal insulation and sound insulation; 5. The bearing capacity of the prefabricated floor is mainly provided by the upper and lower panels. The above-mentioned features of this patent need to exist simultaneously, and its essence is a kind of sandwich floor member. This kind of wallboard is a fully prefabricated wallboard, which has the advantages of large bearing capacity and light weight. However, panels must be installed on the upper and lower sides, which makes its production and installation complicated. The entire wallboard needs to be made very thick, otherwise the panel is prone to deformation or It is broken directly, which makes it occupy the room area and has the disadvantages of high cost.

Chinese Patent Application Publication No. CN107130733A discloses a composite prefabricated wall panel and its manufacturing method and Chinese Patent Application Publication No. CN107190895A discloses a composite prefabricated floor slab and its manufacturing method, which belongs to the field of construction and is a composite wallboard composed of reinforcing ribs and fillers. Composite panels, reinforcing ribs are generally made of reinforced concrete, and fillers are generally made of reinforced concrete or other lightweight materials. This structure can well achieve the goal of integrating thermal insulation, sound insulation and stress. It is a light-weight, high-strength integrated building industrialized building component, but the structure is relatively complex, and there is room for improvement in production efficiency.

Contents of the invention

The purpose of the present invention is to provide a composite laminated board which is easy to manufacture and install, light in weight, low in cost, and good in heat preservation and sound insulation performance in view of the existing composite prefabricated board with complex structure, low production efficiency and high cost.

The present invention is achieved through the following technical solutions:

A composite laminated board includes a reinforced concrete board and a lightweight board body, and the reinforced concrete and the lightweight board body are combined through bonding and/or mechanical connection.

It also includes a reinforcement layer combined with the light board body, and the light board body is between the reinforced concrete and the reinforcement layer. When used in building exterior walls, this reinforced layer together with the reinforced concrete slab acts as the main bearing layer to withstand wind pressure and wind suction, which can effectively increase the bearing capacity of the composite laminated slab.

The composite laminated board is provided with a hole, and the hole is a through hole; the composite laminated board is provided with a notch, and the notch is arranged on one side or a corner of the composite laminated board.

The reinforced concrete slab, the lightweight slab body and the reinforcing layer are bonded and/or mechanically connected to each other. The connection between the plates can be guaranteed as a whole. This connection can be the natural bonding of each layer after forming and hardening, or it can be bonded by adhesive, or connected by bolts, pins, etc., or the above-mentioned way combination.

At least one layer of the composite laminated board is prefabricated in a factory. Composite laminated panels are generally prefabricated in the factory as much as possible. In general, all building walls are prefabricated in the factory, and the floor surface (reinforcement or reinforced concrete slab) is poured on site. The composite laminated plate is stressed and deformed as a whole. Each layer is designed so that the overall force can make full use of the material strength and achieve the purpose of saving material costs.

The material of the light board is aerated concrete or foam concrete or ceramsite concrete or gypsum or light material; the light board is provided with steel bars or fiber materials. The light board body plays the role of heat preservation, sound insulation and reducing the weight of the composite laminated board. When the steel bar or fiber material is arranged in the light board body, the bearing capacity of the composite laminated board can be improved.

The reinforcing layer is reinforced concrete or a mortar layer equipped with steel bars or a mortar layer equipped with steel wire mesh or a mortar layer equipped with fibers or a steel plate or a fiber mesh or a fiber cloth. The role of the reinforcement increases the bearing capacity of the composite laminated plate.

The composite laminated board is a building wall board and/or a building floor board.

Beneficial effects of the present invention: the present invention can be used for the exterior walls and floor slabs of buildings, and can also be used for interior walls; the present invention can be provided with openings and wallboards adapting to various outer contour shapes when needed, and the present invention can be used as Plaster-free wall panels can also be used as exterior wall panels to decorate the exterior walls of the anti-beating process. The invention makes the wallboard a self-insulating light-weight wallboard with integrated bearing and heat preservation by setting the light filler with thermal insulation performance, which is especially suitable for high-rise residential buildings and external wall projects of public buildings. The invention has reasonable structure, good thermal insulation and sound insulation performance, light weight, convenient manufacture and installation, and economy.
