The invention relates to an explosion venting plate and a manufacturing method of the explosion venting plate. The explosion venting plate comprises a body layer, an explosion venting layer, an internally-arranged surrounding frame, an externally-arranged surrounding frame and a middle structure. A hole is formed in the body layer and is filled with the explosion venting layer. The internally-arranged surrounding frame is arranged on the periphery of the explosion venting layer and separates the explosion venting layer from the body layer. The externally-arranged surrounding frame is arranged on the edge around the periphery of the body layer. The middle structure is arranged between the body layer and the explosion venting layer and used for connecting the internally-arranged surrounding frame with the externally-arranged surrounding frame and supporting the internally-arranged surrounding frame. The space between the internally-arranged surrounding frame and the explosion venting layer is filled with flexible seam filling materials. The explosion venting plate has the explosion venting function, meanwhile has the bearing function, and can be used independently.

The invention provides a construction free formwork and a manufacturing method, belonging to the technical field of building materials, including inner steel wire mesh, outer steel wire mesh, thermal insulation core layer, cement column, outer plastering layer and anchor piece; thermal insulation core layer It is located between the inner steel wire mesh and the outer steel wire mesh; there is a pouring hole in the insulation core layer, the pouring hole is set along the vertical direction and runs through the insulation core layer, and the cement column is located in the pouring hole; the outer plastering layer is located on the outer steel wire The outer side of the net; the anchor piece runs through the insulation core layer and is respectively fixed on the inner steel wire mesh and the outer steel wire mesh. The non-dismantling formwork for buildings provided by the present invention can bear the load through the cement columns in the thermal insulation core layer, thereby improving the load-bearing capacity of the non-dismantling formwork for buildings. At the same time, the cement columns also improve the self-rigidity of the thermal insulation core layer, effectively Prevent distortion and deformation of the insulation core layer.

The invention discloses a prefabricated insulation composite wall panel and a manufacturing method thereof, and relates to the technical field of wall panel manufacture. The prefabricated insulation composite wall panel comprises a reinforcing mesh, a plurality of sleeves, a plurality of casing pipes and concrete, wherein the sleeves are arranged on the lower portion of the wall panel, the casingpipes are parallelly arranged along the length direction of the composite wall panel, the concrete is poured on the sleeves, the reinforcing mesh and the peripheries of the casing pipes, the sleeves and the casing pipes are arranged at intervals, the insides of the casing pipes are filled with insulation materials, and the reinforcing mesh is parallel to the length direction of the composite wallpanel. The prefabricated insulation composite wall panel is light in weight, realizes insulation, can be modularly constructed, has waterproof design and can effectively prevent water.

The invention discloses a grass-shaped lake benthic animal collector, which comprises a shell, a cutting board, a net pocket, a load-bearing cardboard and a double pull rope. The shell is fixed under the net pocket, the upper part of the shell is connected with the double pull rope, and the shell is installed inside Cutting board, the exterior of the shell is connected to the load-bearing card board; the cutting board can be used with double pull ropes to complete the cutting of surface sediments; the net bag can prevent the escape of benthic animals during the sample collection process, and can also be used for the initial screening of samples; load-bearing card The plate can determine the thickness of the surface sediment collected by the collector according to the scale line outside the casing; the double pull ropes are respectively connected with the casing and the cutting plate, and the descending and ascending operations of the collector are completed respectively. The grass-shaped lake benthos collector is easy to operate, can simultaneously collect submerged plants in grass-shaped lakes and benthic animals in surface sediments, and can improve the accuracy and efficiency of sampling.

The invention relates to the technical field of a hoisting system, and particularly relates to a keel type thread rack for a whole hot runner hoisting system. The keel type thread rack comprises a rack body, wherein a connecting piece and a thread jamming clamp are arranged on the thread rack body, and the thread rack body comprises a plurality of rod-like main beams; the connecting piece comprises a connecting plate; the thread jamming clamp comprises a thread clamp body which consists of a fixed frame, a mounting plate is arranged at the bottom of the fixed frame, a clamping slot is formed in the mounting plate, and fixed holes are formed in two sides of the clamping slot. According to the keel type thread rack, the main beam plays a certain role in supporting lines and pipelines and has certain bearing capability, and a power line, a temperature sensing line, an oil gas pipeline and a cooling pipeline provided by the whole hot runner system can be separately arranged so as to avoid mutual interference and play safety and protection roles; in addition, the thread jamming clamp is connected with the main beam by adopting a manner of butt-joining the two thread clamp bodies, the installation and regulation are convenient and fast, the rapid installation can be realized, and the design and installation and the follow-up maintenance cost can be reduced.

A locking bottom stud with an automatic leveling function is mainly composed of a bottom stud body base, a fixing rack A, an eccentric wheel A, a transmission column A, a crank A, a stud body, a spring, a base, a fixing rack B, an eccentric wheel B, a transmission column B, a crank B and a rubber blanket. The locking bottom stud has the advantages that the height of the bottom stud can be automatically adjusted, a locking function can be automatically achieved, rigid connection is adopted, the bearing capacity is achieved, the locking bottom stud is simple in structure and convenient to mount and use, and stable operation of a household appliance can be effectively ensured.

The invention relates to a rice straw brick preparation method as well as rice straw bricks and application of the rice straw bricks. According to the invention, rice straw is pre-treated through a NaOH solution with the mass fraction of 2%-5%, the rice straw brick preparation method is optimized from the five aspects of NaOH solution soaking concentration, temperature, soaking time, forming pressure and natural curing time, and optimal preparation conditions and method are established. The preparation method is simple and convenient, the sizes of formed products are changed slightly, and the formed products are low in density and excellent in anticorrosion effect and thermal performance. Through the preparation method, the rice straw is prepared into the straw bricks, and the straw bricks are used as building wall materials, so that improvement on thermal insulation performance of a building is facilitated, application and popularization of the straw bricks for building thermal insulation are facilitated, and the straw bricks are particularly suitable for thermal insulation of agricultural buildings.
