Abstract
The utility model provides a combined through-wall screw rod. The screw rod is divided into three sections; the internal screw rod has length being less than and close to the thickness of the wall body; threads at two ends of the internal screw rod are respectively connected with an internal thread of a connecting nut; the distance between the external end surfaces of the two connecting nuts connected on the internal screw rod is basically equal to the thickness of the wall body; the external sides of the two connecting nuts are respectively connected with one end of an external screw rod by the thread; the other end of each screw rod is provided with a thread that is connected with a fastening nut by the thread; and the external end surface of the connecting nut is indirectly contacted with a tyre plate by a position-limited pad with the diameter of the central through hole larger than that of the external screw rod. In the utility model, partial parts can be repeatedly used, an additional positioning rod is not needed, therefore a large amount of metal materials can be saved; the structure is simple, the installation and disassembly are convenient, the labor intensity is small, the construction cost is low, the period is short, the error is small, the positioning is exact, the quality is stable and reliable, and the operation is safe.
Description
Technical field the utility model relates to the auxiliary accessories that a kind of building trade is used.
Background technology is present, a large amount of mine dam lead screw through walls of using on building trade, its structure is: it has a lead screw, and this lead screw is positioned at the outer two ends of tire plate and is respectively equipped with the nut that is engaged with, and the lead screw middle part that has also is provided with perpendicular water bar.During use, this lead screw is vertically passed two parallel tire plates, and it is positioned at the outer part of two tire plates and vertically passes two steel pipe arranged side by side and the ingot pressing plates of being done sept by flitch again, and the end is located by clamp nut.Be to guarantee the thickness of body of wall, between two tire plates, establish two ends specially and vertically withstand on backstay on the tire plate.After the mortar between the two tire plates is frozen into body of wall, need to remove the auxiliary accessories that is positioned at outside the body of wall, promptly dismantle successively clamp nut, ingot pressing plate, steel pipe, flitch, cut away being exposed at the outer lead screw of tire plate, take off the tire plate, and then the lead screw that will be exposed at outside the body of wall cuts away, take off the tire plate, and then will be exposed at the outer lead screw of body of wall and cut away, polishing afterwards is positioned at the outer lead screw of body of wall, so that descend waterproofer's preface one.Because the lead screw self structure is limit, and makes it to exist some defective: 1, repeatedly cutting is thoroughly scrapped whole lead screw, because this lead screw consumption is many, wastes surprising; The spark that produces when 2, polishing splashes everywhere, and operation is very dangerous; 3, every lead screw all will be cut four times, complex operation, and labour intensity is big, the operating cost height, construction period is long; 4, backstay is subject to the mortar impact and is shifted, comes off when the cast mortar, thus the effect of thickness of wall body out of hand.
The summary of the invention the purpose of this utility model is to provide a kind of raw material, simple, construction cost combined type low, job safety lead screw through walls of loading and unloading of saving.
The utility model also includes lead screw and reaches the hold-down nut of two ends engagement with it, and wherein lead screw is divided into three sections, and promptly one section internal thread bar and two sections outside nut bars are linked to each other by the attaching nut between the Inside and outside screw bar.Above-mentioned internal thread bar be a length less than and can place lead screw in the body of wall near thickness of wall body, its both ends (or all) are provided with screw thread, its each be connected with attaching nut's inside thread.Distance between above-mentioned two attaching nut outer faces that are connected on the internal thread bar equals thickness of wall body substantially, for preventing that occurrence positions changes between attaching nut and the internal thread bar, can adopt welding or special process for stamping with both fixed-site.Above-mentioned two attaching nut outer faces that are connected on the internal thread bar contact with the tire plate, to replace backstay of the prior art to limit thickness of wall body, because the tire plate is wooden softer, and the attaching nut is the harder of metal, it gives the local externally applied forces of tire plate fragile tire plate, preferably attaching nut outer face and tire plate are by spacing pad mediate contact, and this spacing pad is the pad of central through hole diameter greater than the outside nut shank diameter.The middle part of best above-mentioned internal thread bar is provided with perpendicular continuous water bar.Each is connected with an outside nut bar threaded one end again in the above-mentioned two attaching nuts outside, and this two outside nuts bar and above-mentioned internal thread bar constitute a lead screw.Above-mentioned two outside nut bars are the lead screw that both ends (or all) are provided with screw thread, and the other end of this outside nut bar is provided with the screw thread that is threaded with clamp nut.
During use, select length and body of wall to connect the near internal thread bar of thickness, its two ends link to each other with attaching nut's inboard respectively, make the distance of attaching nut's both ends of the surface equal thickness of wall body substantially.Two blocks of vertical with it tire plates are abutted on attaching nut outer face or the spacing pad, the outside nut bar vertically passes through hole corresponding with it on the tire plate, be connected with attaching nut's outside screw, this lead screw is positioned at the outer part of tire plate and vertically passes two steel pipe arranged side by side and the ingot pressing plates of being made sept by flitch again, and the end is located by clamp nut.
The utility model compared with prior art has following advantage:
1, part parts (outside nut bar) are reusable, and part in addition with the backstay location, can not saved a large amount of metal material within the walls.
2, simple in structure, installation and removal are all convenient, labour intensity is little.
3, construction cost is low, the cycle is short, and error is little, the location is accurate, steady quality is reliable.
4, job safety.
Description of drawings
Fig. 1 is that schematic diagram cuts open in the utility model user mode office.
Fig. 2 is that schematic diagram cuts open in the office of the utility model lead screw.
The specific embodiment is in the schematic diagram of combined type lead screw through walls illustrated in figures 1 and 2, and this lead screw through walls includes lead screw and reaches the clamp nut of two ends engagement with it, and wherein lead screw is divided into three sections, i.e. one section internal thread bar 1 and two sections outside nut bars 2.The internal thread bar be a length less than and near the lead screw of thickness of wall body, the middle part is provided with perpendicular continuous water bar 3.Each is connected the screw thread at these internal thread bar both ends with attaching nut's 4 inside threads.Distance between above-mentioned two attaching nut outer faces that are connected on the internal thread bar equals thickness of wall body substantially, and attaching nut outer face and tire plate are by spacing pad 5 mediate contacts of central through hole diameter greater than the outside nut shank diameter.Each is connected with an outside nut bar threaded one end again in above-mentioned two attaching nuts outside, and the above-mentioned two outside nut bar other ends are provided with the screw thread that is threaded with clamp nut.This lead screw is positioned at tire plate 6 outer parts and vertically passes two steel pipe 8 arranged side by side and the ingot pressing plates 9 of being made sept by flitch 7 again, and the end is by clamp nut 10 location.
