Abstract
The utility model discloses a fixed structure for an access door-frame of a low-temperature cold storage, which comprises a doorway enclosure and a door-frame. The door-frame comprises an inner door-frame and an outer door-frame; a rail is connected between the inner door-frame and the outer door-frame through tenon-and-mortise, and the inner door-frame and the outer door-frame are connected into a whole by the rail; L-shaped right-angled steel plates fixed by self-tapping screws are uniformly arranged on the inner door-frame and the outer door-frame; and the other lateral plate of each L-shaped right-angled steel plate is fixed on a doorway maintenance structure through an expansion bolt. In the utility model, the door-frame and the doorway enclosure are connected through the expansion bolts and the L-shaped right-angled steel plates, belonging to rear-anchoring structure, so that the adjustment is easy, the installation is convenient and fast, and the popularization is convenient.
Description
Technical field
The utility model relates to a kind of doorframe fastening structure, is specifically related to a kind of fixed structure that is used for low-temperature cold-storage inlet doorframe.
Background technology
Continuous quickening along with China's urbanization progress, the rapid growth of extensive expansion, migration and the population in city, the rapid loss that the cities and towns periphery is ploughed, the food supply of urban population relies on the freezer of all kinds of distribute types more as transfer and collecting and distributing place, and the food place of production, processing factory and townsfolk's food supply is connected.Freezer passes through artificial cooling, make the certain low temperature of indoor maintenance, be mainly used in the freezing processing and the refrigeration of food, its wall, floor and flat-top all are laid with certain thickness heat-barrier material, to reduce the heat that the external world is imported into, Cold Storage Building is different with general industry and civilian construction, and it has own particular structure and quality requirement, comprises thermal insulation, sealing, soundness, frost resistance etc.
Storehouse, it is refrigerated storage room, it is most important main building in the freezer, it is the cryopreservation zone, the space enclosing structure of six faces in refrigerated storage room space to insulation, keep the storehouse temperature constant, every vapour, fire prevention very high requirement arranged, so refrigerated storage room space enclosing structure working procedure complexity, the number of plies is many, thereby has caused also more complicated of cold sotrage door inlet oral area structure.Refrigerated storage room inlet oral area is very big to the use influence of refrigerated storage room, and it mainly is made up of three parts from outside to inside: between cold sotrage door/air curtain, door opening (comprising inlet ground, doorframe and door pocket), the withdrawal of currency from circulation.
Doorframe and structure is connected as shown in Figure 1 in the existing freezer, in early days, the wall heat insulation material more than 10 of freezer adopts 700 thick rice husks, its pressure to doorframe (cover) is bigger, doorframe hair shelves 4 adopt the mode that concrete block and pre-embedded bolt are set on door opening gusset protection structure body of wall to fix, this kind built-in fitting fixed structure has the intensity height, the advantage of good endurance; Nowadays, freezer side wall heat insulating material great majority adopt the lower polyurethane of thermal conductivity, thickness reduces greatly, the template on border when door pocket, architrave just spray as the polyurathamc insulation layer, heat insulating material almost can be ignored to the pressure of doorframe (cover), tradition built-in fitting fixed structure has just become a burden, the fixing construction of built-in fitting is complicated, work efficiency is low, and its permanent position precision is difficult to guarantee, this just makes, and the doorframe that assembles is installed very difficulty, also is the comparison difficulty even split into that the doorframe of loose mail will accurately install.
Summary of the invention
The utility model purpose provides a kind of adjustment, low-temperature cold-storage quick and easy for installation inlet doorframe fixed structure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of low-temperature cold-storage inlet doorframe fixed structure, comprise door opening space enclosing structure and doorframe, doorframe and exterior door frame in described doorframe comprises, the tenon fourth of the twelve Earthly Branches is connected with crosspiece in the middle of the inside and outside doorframe, described crosspiece is connected as a single entity inside and outside doorframe, evenly is furnished with the fixing L shaped right angle steel plate of self-tapping screw on described crosspiece and the inside and outside doorframe, and the opposite side panel of L shaped right angle steel plate is fixed in the door opening space enclosing structure by expansion bolt.
Above, described door opening space enclosing structure is made of ground and door opening both sides constructional column, fixedlys connected with L shaped right angle steel plate by expansion bolt between described doorframe and the door opening space enclosing structure, belongs to the back anchor structure, is easy to adjust, and is quick and easy for installation; Though connectors such as the L shaped right angle steel plate of connection exterior door frame, expansion bolt belong to metal material, thermal conductivity is higher, but it is buried in heat insulating material after finishing, the exterior door frame connector is fixed on the peripheral structure, and the peripheral structure of cold store belongs to heat inertia index greater than 6 heavy type structure, and the heat fade degree is very big, time delay is very long, low temperature reaches the surface temperature influence after the space enclosing structure decay just very little, about below 0.2 ℃, so can not cause any dewfall situation.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the utility model is connected doorframe and door opening space enclosing structure by expansion bolt with L shaped right angle steel plate, belongs to the back anchor structure, is easy to adjust, and is quick and easy for installation, the work efficiency height;
2, connector such as the expansion bolt on the exterior door frame, L shaped right angle steel plate is buried in heat insulating material in doorframe (cover) completion back in the utility model, can not form obvious cold bridge or cause dewfall;
3, the utility model is simple in structure, is easy to realize, is fit to promote the use of.
