The connector matched somebody with somebody, explosion-proof or shellproof Protection Product such as explosion proof fence is connected as by the high-strength cell board of polylith two-by-two, improves protection production
The explosion-proof performance of product.The intensity of the connector can be determined according to being actually needed, in order to avoid the different high-strength lists of Protection Product
Disconnected between first plate by explosive blast events, the connector of high intensity may be selected, such as high temperature part or high intrusion
Bar matches connection with the position that high-strength cell board both sides are used to connect.
The position that every piece of high-strength cell board both sides are used to connect can determine according to being actually needed, different high-strength cell boards two
The structure at the position that side is used to connect can be identical or different, and the application embodiment does not limit this.
In one embodiment, the position that the both sides of high-strength cell board are used to connect can be concaveconvex structure, that is, described
The both sides of at least one of the high-strength cell board of polylith high-strength cell board are respectively formed with concaveconvex structure.For example, high-strength cell board
Both sides can form concaveconvex structure by modes such as cuttings, and cutting mode may include but be not limited to respectively symmetrical cutting, divide equally not
Symmetrical expression cutting, do not divide equally symmetrical cutting and do not divide equally asymmetric formula cutting so that the high-strength cell board both sides are formed respectively
Concaveconvex structure accordingly in dividing equally symmetrical distribution, divide equally asymmetric formula distribution, do not divide equally symmetrical distribution or do not divide equally
Asymmetric formula distribution;Wherein, it is preferred to use divide equally symmetrical cutting mode and the both sides of high-strength cell board are cut, in this way,
The both sides of high-strength cell board form respectively symmetrical concaveconvex structure, since the high-strength cell board with the structure is being subject to
The power expanded outwardly during shock, expanded is basically identical, therefore has more preferable explosion-proof performance.High-strength cell board two
The cutting of side can be carried out by cutting equipment, and the cutting equipment may include but be not limited to water sand cutting machine.
Might as well be by taking the high-strength cell board with structure shown in Fig. 3 a or similar structures as an example, will using different cutting modes
At least one section of through hole is respectively cut into through hole of the high-strength cell board per side so that high-strength cell board both sides respective described at least one
Duan Tongkong is in that respectively symmetrical expression is distributed, respectively asymmetry formula is distributed, respectively symmetrical expression is distributed or respectively asymmetry formula is divided
Cloth.
For example, respectively symmetrical cutting can be carried out to the position at least formed with through hole of high-strength cell board both sides, in this way,
The through hole of high-strength cell board both sides is cut into multistage through hole respectively, three sections of through holes as shown in Figure 5 a or as shown in Figure 5 b
The length all same of two sections of through holes, each section of through hole length and the through hole being cut (i.e. divide by the length of convex portion and recess
Length is identical), and every piece of high-strength cell board both sides are respectively cut the multistage through hole to be formed and are distributed in symmetrical.Due to respectively
The power basic one that the high-strength cell board of symmetrical concaveconvex structure is expanded outwardly when being subject to shock, expanded
Cause, therefore the explosion proof fence that the high-strength cell board based on respectively symmetrical concaveconvex structure assembles is with preferably anti-
Quick-fried performance.
In another example respectively asymmetric formula cutting can be carried out to the position at least formed with through hole of high-strength cell board both sides,
In this way, the through hole of high-strength cell board both sides is cut into multistage through hole respectively, and two sections of through holes as shown in Figure 6, each section of through hole length
Spend and the length of through hole that is cut is not quite similar that (length of such as each convex portion is identical, but the length of convex portion and recessed
Partial length is different), and it is in that asymmetric formula is distributed that the multistage through hole to be formed, which is respectively cut, in every piece of high-strength cell board both sides.
In another example the position at least formed with through hole of high-strength cell board both sides can be carried out not divide equally symmetrical cutting,
In this way, the through hole of high-strength cell board both sides is cut into multistage through hole respectively, and three sections of through holes as shown in Figure 7, each section of through hole length
Spend and the length of through hole that is cut is not quite similar that (length of such as each convex portion is identical, but the length of convex portion and recessed
Partial length is different), and every piece of high-strength cell board both sides are respectively cut the multistage through hole to be formed and are distributed in symmetrical.
Cut in another example can not divide equally asymmetric formula to the position progress at least formed with through hole of high-strength cell board both sides
Cut, in this way, the through hole of high-strength cell board both sides is cut into multistage through hole, multistage through hole as shown in Figure 8, each section of through hole respectively
Length and the length for the through hole being cut be not quite similar (length of such as each convex portion or each recess point is not exactly the same,
And the length of the length and recess of convex portion point is also not exactly the same), and every piece of high-strength cell board both sides are respectively cut what is formed
Multistage through hole is in that asymmetric formula is distributed.
The high-strength cell board that the application embodiment provides is the integrally formed entirety of raw material, using Fig. 5 a, Fig. 5 b and
Cutting mode shown in Fig. 7, the fracture that can retain high-strength cell board raw material as far as possible in two ends of high-strength cell board are strong
Degree, that is to say, that all at least part of raw material in two ends of high-strength cell board are not switched off, the raw material being not switched off
Continuously distributed principle example can be found in shown in Fig. 5 c and Fig. 5 d, it is seen that the part being not switched off in end and high-strength cell board
In corresponding center section raw material fracture strength it is big, it is explosion-proof etc. to improve so as to make full use of its material property
Level, this is because the material of same horizontal plane is not cut off in high-strength cell board, circumferential direction is continuous.By two pieces of high-strength lists
First plate is removed and assembled into Protection Product in explosion proof applications, and end is the junction of different high-strength cell boards, and it is explosion-proof should
The part blown up or damaged is easiest in, and uses Protection Product obtained by the high-strength cell board assembling after program cutting,
The fracture strength for the raw material being not switched off can be made full use of between different high-strength cell boards, and then is effectively increased explosion-proof etc.
Level.By that to the high-strength flexible cutting mode in cell board both sides, can meet the assembling demand of different size anti-explosion product, application is non-
Often extensively.For example, cutting after polylith high-strength cell board between be two-by-two a tubular structure by connector detachable connection,
An i.e. available explosion proof fence, simple, convenient, flexible, the explosion-proof performance of explosion proof fence protrudes.Next further illustrate
Connection mode between wantonly two pieces adjacent high-strength cell boards is, it is necessary to illustrate, example below is merely illustrative, ability
Field technique personnel can be attached under this technical inspiration using other similar connections mode, these the same or similar connection sides
Formula is belonged in the protection domain of the application.
Alternatively, at least two pieces adjacent high-strength cell boards can be inserted using high duty metal in the high-strength cell board of the polylith
Bar mode carries out detachable connection, specifically, at least two pieces adjacent high-strength cell boards in the high-strength cell board of polylith
The concaveconvex structure that is each formed of sides adjacent it is complementary, the concaveconvex structure be through hole, two pieces interspersed successively by the inserted link
Each through hole of the sides adjacent complementation of adjacent high-strength cell board, using by two pieces of adjacent high-strength cell board detachable connections as one
Body.For example, any cutting modes of Fig. 5 a- Fig. 8 such as can be used to form the logical of multistage protrusion respectively in the both sides of high-strength cell board
Hole, by the complementary alignment of the concaveconvex structure of two pieces of high-strength cell board sides adjacents, (convex portion of one piece of high-strength cell board corresponds to another high
