Abstract
The utility model discloses a detachable embedded piece for an outer wall formwork. The detachable embedded piece for the outer wall formwork comprises an external bolt and an embedded bolt, wherein one end of the external bolt is provided with adjustable threads, and one end of the embedded bolt is provided with fixed threads. An E-shaped clamp and an adjustable nut are arranged in the position of the adjustable threads from inside to outside in sequence, wherein the E-shaped clamp is sleeved at the position of the adjustable threads, and the adjustable nut is connected at the position of the adjustable threads in a threaded mode. The other end of the external bolt is provided with a fixed nut. The external bolt and the embedded bolt are connected with each other through the fixed nut and the fixed threads. The detachable embedded piece for the outer wall formwork is simple in structure, convenient to manufacture, low in production cost, reusable, high in utilization rate, and low in usage cost. When the detachable embedded piece for the outer wall formwork is used, the embedded bolt is embedded into a wall body in advance, and the end portion provided with the fixed threads is made to extend out of the wall body for 20-30mm. When the outer wall formwork of a shear wall is installed, the external bolt is connected to the exposed end portion provided with the fixed threads of the embedded bolt through the fixed nut, the adjustable nut is screwed up, and the outer wall formwork of the shear wall is pressed tightly through the E-shaped clamp, a round pipe and square timber. After pouring of concrete is finished, the embedded bolt stays in the wall body, the embedded bolt is hidden in a plastering layer of an outer wall, and therefore the embedded bolt which is embedded into the wall body in advance does not need to be cut.
Description
Technical field
The utility model belongs to the pre-buried technical field of tools of concrete shear wall structure exterior wall, particularly the detachable built-in fitting of a kind of outer wall template.
Background technology
At present, in building construction process, during cast-in-situ concrete shear wall structure external wall construction, need be in the shear wall body of wall pre-embedded bolt, be used for reinforcing the shear wall outer wall template.Traditional construction method is pre-buried harness cord through-wall bolt in body of wall, and material cost is higher; And before external wall plastering, need carry out cutting process to the pre-embedded bolt on the shear wall body of wall, and to waste time and energy, labour intensity is big, and operating efficiency is low.
The utility model content
The utility model provide a kind of simple in structure, be convenient to make, with low cost, can reuse and the detachable built-in fitting of outer wall template that utilization rate is high.
For achieving the above object, the technical solution of the utility model is: the detachable built-in fitting of a kind of outer wall template, comprise that an end is provided with the external bolt of regulating screw thread and the pre-embedded bolt that an end is provided with retaining thread, regulate the screw thread place and from inside to outside be arranged with mountain type card successively and be bolted with adjusting nut; External bolt other end end is provided with hold-down nut, and external bolt links to each other with retaining thread by hold-down nut with pre-embedded bolt.
Described hold-down nut is provided with the rinforcement bar that links to each other with external bolt.
The length of described external bolt and pre-embedded bolt is 250mm, and the length of regulating screw thread and retaining thread is 100mm.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises that an end is provided with the external bolt of regulating screw thread and the pre-embedded bolt that an end is provided with retaining thread, regulates the screw thread place and from inside to outside is arranged with mountain type card successively and is bolted with adjusting nut; External bolt other end end is provided with hold-down nut, and external bolt links to each other with retaining thread by hold-down nut with pre-embedded bolt, and it is simple in structure, is convenient to make, and low production cost can reuse, the utilization rate height, and use cost is low; During use, pre-embedded bolt is nuzzled in the body of wall in advance, make the retaining thread end stretch out 20～30mm outside the body of wall; When the shear wall outer wall template is installed, external bolt is connected the retaining thread end that pre-embedded bolt exposes by hold-down nut, screws adjusting nut, compress the shear wall outer wall template by mountain type card, pipe and the lumps of wood; Concreting finishes, and the shear wall outer wall template is removed the back and removed external bolt, and pre-embedded bolt is stayed in the body of wall, when external wall plastering, pre-embedded bolt is directly hidden in the exterior wall floated coat, need not to cut the pre-embedded bolt that is embedded in the body of wall, can save the engineering time greatly, increase work efficiency.
2, be provided with the rinforcement bar that links to each other with external bolt unthreaded portion at hold-down nut, can improve structural strength, can effectively increase the service life.
3, the utility model is applicable in any shear wall exterior wall seam areas template construction that comprises basement, and construction meets code requirement, and quality is guaranteed, is easy to promote, and has good economic and social benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the pre-buried schematic diagram of pre-embedded bolt among Fig. 1;
Fig. 3 is use view of the present utility model.
The specific embodiment
As Fig. 1, Fig. 2 and the detachable built-in fitting of outer wall template shown in Figure 3, it comprises that length is external bolt 1 and the pre-embedded bolt 7 of 250mm, external bolt 1 left end is provided with regulates screw thread 2, external bolt 1 right-hand member end is provided with hold-down nut 5, pre-embedded bolt 7 left ends are provided with retaining thread 71, and external bolt 1 is fixedly linked by hold-down nut 5 and retaining thread 71 with pre-embedded bolt 7.2 places from inside to outside are arranged with mountain type card 3 successively and are bolted with adjusting nut 4 at the adjusting screw thread, and type card 3 inboards, mountain are provided with pipe 11 and the lumps of wood 10, screw adjusting nut 4, make mountain type card 3 compress pipe 11 and the lumps of wood 10.In order to improve structural strength, be provided with the rinforcement bar 6 that links to each other with external bolt 1 unthreaded portion at hold-down nut 5, can effectively increase the service life.
In the present embodiment, external bolt 1 and pre-embedded bolt 7 are made by the waste material that the cutting of outer wall of basement sealing bolt produces, and can effectively utilize waste material, improve stock utilization; The length of external bolt 1 and pre-embedded bolt 7 is 250mm, and the length of regulating screw thread 2 and retaining thread 71 is 100mm, rinforcement bar 6 be diameter 6mm.
When the utility model used, specific operation process was: in the body of wall 8 of 1, pre-embedded bolt 7 being nuzzled in advance, make retaining thread 71 ends stretch out 20～30mm outside the body of wall 8; When 2, shear wall outer wall template 9 is installed, external bolt 1 is connected retaining thread 71 ends that pre-embedded bolt 7 exposes by hold-down nut 5, screws adjusting nut 4, compress shear wall outer wall template 9 by mountain type card 3, pipe 11 and the lumps of wood 10; 3, concreting finishes, and shear wall outer wall template 9 is removed the back and removed external bolt 1, and pre-embedded bolt 7 is stayed in the body of wall 8, and when external wall plastering, pre-embedded bolt 7 is directly hidden in the exterior wall floated coat.
