The invention discloses a prefabricated assembled type steel structure house building system and a construction method thereof. The prefabricated assembled type steel structure house building system comprises groups of connecting bolts, prefabricated slabs and sets of connecting assemblies. The connecting bolts are arranged on a building foundation according to building pattern. The prefabricated slabs are divided into wall prefabricated slabs, window prefabricated slabs and door prefabricated slabs, wherein front slabs, back slabs and light steel frames of the window prefabricated slabs and the door prefabricated slabs are respectively provided with window openings and door openings, and windows and doors are respectively installed at the positions of the window openings and the door openings. The connecting assemblies correspond to the connecting bolts in a one-to-one mode, and one group of connecting bolts at the corresponding positions penetrate bases of central square pipes at the bottoms of the connecting assemblies to be matched with nuts so as to enable the connecting assemblies to be fixed on the building foundation according to the building pattern. The prefabricated slabs are combined with the connecting assemblies at the corresponding positions according to the building pattern to erect a building frame. A wall of the prefabricated assembled type steel structure house building system is modular and is broken up into parts, so that garbage and noise produced by slab cutting in a field are decreased while transportation is facilitated.

The invention discloses a box body and a refrigeration device, which includes a box shell and an inner tank, the inner tank is placed in the box shell, and further includes: a second spacer arranged between the box shell and the inner tank A flow guide part and a second flow guide part, wherein, the first flow guide part and the second flow guide part are respectively closely attached to the rear wall of the inner tank and the rear wall of the case to form a vertical Extended diversion channels. By changing the structure of the sheath of the air return pipe on the outside of the inner tank, the first deflector is formed to cooperate with another deflector on the outside of the inner tank, which increases the flow area of ​​the guide channel, and can effectively improve the inner tank and the box shell. The foaming efficiency and quality of the foaming material in the cavity are improved. At the same time, the integration of the deflector and the return air pipe sheath reduces manufacturing costs, reduces on-site operations, and improves production efficiency.

The invention provides a combined operating system for combined radiotherapy and imaging diagnosis, and relates to the technical field of medical imaging diagnosis equipment. The system includes: high-energy photon accelerators and cyclotrons arranged in the first area; positron emission computed tomography PET equipment arranged in the second area; computed tomography CT equipment arranged in the third area; A four-zone magnetic resonance imaging MRI apparatus; a plate that carries and restrains the subject in a fixed position thereon; and a shifter that controls the movement of the plate between the zones. The invention can reduce the damage caused by the rays to the operator and improve the treatment and diagnosis accuracy of the system.

The invention relates to a sandwich heat-preserving decorative board with mixed hollow porous fiber reinforced heat-preserving mortar and a manufacturing method.A heat-preserving core veneer of the heat-preserving decorative board is a formed veneer and provided with big and round through holes; a hanging part capable of being positioned is arranged at the inner side of a back plate and tightly attached to the back face of the heat-preserving core veneer, and the same big and round through holes are formed in the positions corresponding to the big and round holes in the heat-preserving core veneer; the ends of the hanging part capable of being positioned are provided with small and round holes, square holes and right-angled hooks used for connecting, installing and lapping the heat-preserving decorative board in a positioning mode; fiber grid cloth is arranged at the inner side of a panel and is spaced from the heat-preserving core veneer by 2 mm; the mixed hollow porous fiber reinforced heat-preserving mortar is poured into the periphery of the heat-preserving core veneer through sealed formworks, the panel, the back plate and sealed edges are formed after the mortar is hardened, and bridge-cutoff shear connectors are formed in the big and round holes; the decorative board has the advantages that a good integrated space stress structure is formed through overall pouring of the panel, the back plate, the bridge-cutoff shear connectors and the sealed edges, positioning and splicing are accurate, and the fireproof performance is improved.

The invention discloses a box body and a refrigeration device, which includes a box shell and an inner tank, the inner tank is placed in the box shell, and further includes: a second spacer arranged between the box shell and the inner tank A flow guide part and a second flow guide part, the first flow guide part and the second flow guide part are respectively closely attached to the rear wall of the inner tank and the rear wall of the box shell to form a vertically extending A flow guide channel; wherein, the first flow guide part is a hollow sleeve; the second flow guide part is a flat sheet-shaped second guide piece. By changing the structure of the sheath of the air return pipe on the outside of the inner tank, the first deflector is formed to cooperate with another deflector on the outside of the inner tank, which increases the flow area of ​​the guide channel, and can effectively improve the inner tank and the box shell. The foaming efficiency and quality of the foaming material in the cavity are improved. At the same time, the integration of the deflector and the return air pipe sheath reduces manufacturing costs, reduces on-site operations, and improves production efficiency.

The invention relates to a concrete crack width measuring instrument suitable for remote monitoring and a measuring method, which is mainly used for local automatic interpretation of the concrete crack width. The hardware module part includes camera, image acquisition module, DSP, image display module, network module, external storage space, interrupt control module, display and peripheral circuits. The image acquisition module converts the acquired analog video signal into a digital signal and sends it to DSP for processing. After the DSP receives the digital video signal, it processes the crack image, calculates the crack width value, and then sends the digital video signal with the crack width value to the network module or image display module. The processing methods mainly include image interception, image segmentation, anti-color processing, area marking, small area elimination, width measurement, image scale, width display, and output image synthesis. The invention reduces errors in concrete crack width measurement to a certain extent, and facilitates real-time monitoring of dangerous cracks.
