Abstract
The utility model discloses a main back of body is stupefied for knee wall phantom board, wall form is through the stupefied and typed wall bolt support of stupefied, the inferior back of the body of the main back of the body, the main back of the body is stupefied to include that two have the square pipe of certain length and the nozzle stubs of two connection usefulness, parallel arrangement and justify align are managed in two sides, respectively set up one between the both ends of two square pipes the nozzle stub, the nozzle stub with two side's sealing of tubes, distance between the two sides pipe slightly is greater than typed wall bolt's diameter, the cross section of two square pipes is rectangle or square. This owner carries on the back stupefied stable in structure, convenient to use, is convenient for deposit.
Description
Technical field
The utility model relates to building-supporting field, particularly relates to a kind of main back cord for supporting wall form.
Background technology
The back-supported of wall form is made up of two-layer keel, and the keel of direct support shuttering are secondary joist, also claims time back cord; For support internal layer keel for main joist, also claim main back cord.When being assembled into wall form, by the template drawknot of through-wall bolt by body of wall both sides, each through-wall bolt becomes the fulcrum of outer keel.
Early stage main joist or secondary joist are made by round log or the lumps of wood, widely use steel pipe at present, or secondary joist adopts the lumps of wood, main joist to adopt round steel pipe.But, use round log or the lumps of wood all can waste a large amount of forest reserves, and the easy breaking out of fire in storage process of round log or the lumps of wood; When adopting round steel pipe, circular configuration is unstable, is not easy to install.
Summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of Stability Analysis of Structures, be convenient to install and be easy to the main back cord of body of wall that stores.
For this reason, the technical solution of the utility model is as follows:
A kind of main back cord for supporting wall form, described wall form is supported by main back cord, secondary back cord and through-wall bolt, described main back cord comprises the short tube that two square tubes with certain length are connected with at least two, and described two square tubes be arranged in parallel and justify align; At least between the two ends of two square tubes, respectively arrange a described short tube, described short tube welds with described side cross tube; Distance between described side cross tube is slightly larger than the diameter of described through-wall bolt.
The cross section of described two square tubes is rectangle or square.
The length of described side cross tube is 50cm, and the distance between side cross tube is 2mm.
Described square tube and short tube are steel pipe or other suitable metal tube.
Main back cord for supporting wall form of the present utility model is made of metal, so save the forest reserves, and not easily initiation fire again; In addition, main back cord main body is square tube, and compared with round steel pipe, its structure is more stable, is convenient to install and deposit.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of main back cord of the present utility model;
Fig. 2 is the structural representation of another embodiment of main back cord of the present utility model.
Detailed description of the invention
Be described in detail below in conjunction with the structure of accompanying drawing to the main back cord of body of wall of the present utility model.
As shown in Figure 1, the main back cord for supporting wall form of the present utility model comprises: two have the square tube 10 of certain length and two short tubes be connected 11, and described two square tubes 10 be arranged in parallel and justify align; Between the two ends of two square tubes 10, respectively arrange a described short tube 11, short tube 11 welds with side cross tube 10; Distance between side cross tube 10 is slightly larger than the diameter of through-wall bolt, so that through-wall bolt passes between side cross tube 10, main back cord and time back cord is locked.
Another embodiment as shown in Figure 2, for improving intensity, can also be welded with a short tube 11 in the position between the middle part of two square tubes 10.
The shape of cross section of two square tubes 10 can be rectangle also can be square, and page is fixed according to specific needs.
The length of two square tubes is 50cm, and distance is therebetween 2mm.
Described square tube 10 and short tube 11 are steel pipe or other suitable metal tube.
Above exemplary description is done to the utility model; should be noted that; when not departing from core of the present utility model, any simple distortion, amendment or other those skilled in the art can not spend the equivalent replacement of creative work all to fall into protection domain of the present utility model.
