Technical Field
The utility model relates to a tubular prefabricated bolt hole die, and belongs to the field of auxiliary tools for constructional engineering.
Background
At present, when large-scale equipment such as a mill and the like is installed, large-scale foundation bolts are usually required, a narrow wood board is enclosed into a long cylinder by a traditional bolt hole die, and the wood board is lifted out before the concrete is finally set after external grouting; the method is greatly influenced by factors such as environment, worker technology and the like, the conditions such as hole collapse or incapability of being lifted by a wood board are easy to occur due to careless operation, and once the conditions occur, manpower, materials and construction period are wasted.
Disclosure of utility model
The utility model aims to solve the technical problems that: the defect of the prior art is overcome, the tubular prefabricated bolt hole die is provided, the risk of hole collapse is solved by using the tubular prefabricated bolt hole die, labor and construction period are saved, a good construction effect is ensured, waste pipelines are utilized, material waste is reduced, funds are saved, and the environment is protected.
The tubular prefabricated bolt hole die comprises a support tube, wherein the bottom end of the support tube is fixedly connected with a lower sealing plate, a plurality of through holes are formed in the tube wall of the support tube, reinforcing steel bars are inserted into the through holes and welded and fixed with the support tube, and the reinforcing steel bars extend into the support tube and extend out of the support tube simultaneously.
The support tube adopts an old steel tube to replace a traditional wooden screw box to be used as an anchor bolt hole die; the lower sealing plate seals the bottom end of the support tube, so that concrete is prevented from entering the tube from the bottom end of the support tube. When the anchor bolt is used, the structure is placed at a designated position, then concrete pouring is carried out, and after the pouring is finished, the support pipe does not need to be taken out, so that the problem of hole collapse does not occur, the construction effect is ensured, after the concrete outside the support pipe is solidified, the anchor bolt is inserted into the support pipe, and then grouting in the pipe is carried out, so that the anchor bolt is fixed; because the bolt hole die is not required to be put forward, other works can be completed by workers within waiting time, and labor and construction period are saved. The reinforcing steel bars extend into the support tube and out of the support tube simultaneously, and the concrete poured in the later stage is anchored with the tube wall of the support tube, so that the support tube and the concrete fixing block can be firmly combined. The pipe diameter of the support pipe is larger than the diameter of the foundation bolt, so that the thickness of concrete between the support pipe and the foundation bolt is ensured to be large enough, and the strength is high enough.
Preferably, the outer edge of the lower sealing plate is larger than the pipe diameter of the supporting pipe, so that the reliable combination of the supporting pipe and the concrete is further ensured.
Preferably, the distance between the outer edge of the lower sealing plate and the outer tube wall of the supporting tube is 60mm-100mm.
Preferably, the length of the reinforcing steel bars outside the support tube is 100mm-130mm, and the length of the reinforcing steel bars inside the support tube is 10mm-30mm, so that the support tube and the concrete outside and inside the support tube can be reliably fixed.
Preferably, the reinforcing steel bars are uniformly arranged on the supporting tube, and the setting heights of the reinforcing steel bars are not uniform, so that the supporting tube and the concrete outside and inside the supporting tube can be reliably fixed.
Compared with the prior art, the utility model has the following beneficial effects:
The utility model has simple structure, reasonable design, simple assembly and easy popularization; the risk of hole collapse is completely avoided, the structural strength is high, the construction effect is guaranteed, the labor and the construction period are saved, the better construction effect is guaranteed, the waste steel pipes are fully utilized, the material waste is reduced, the fund is saved, and the environment is protected.

FIG. 2 is a view showing the state of use of the tubular prefabricated bolt hole die.
In the figure: 1. a support tube; 2. reinforcing steel bars; 3. a lower sealing plate; 4. a bolt; 5. and (3) concrete.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
Referring to fig. 1 and 2, the tubular prefabricated bolt hole die of the utility model comprises a support tube 1, wherein the bottom end of the support tube 1 is fixedly connected with a lower sealing plate 3, the tube wall of the support tube 1 is provided with a plurality of through holes, reinforcing steel bars 2 are inserted into the through holes, the reinforcing steel bars 2 are fixedly welded with the support tube 1, and the reinforcing steel bars 2 extend into the support tube 1 and extend out of the support tube 1 simultaneously.
In this embodiment:
The outer edge of the lower sealing plate 3 is larger than the pipe diameter of the support pipe 1, so that the reliable combination of the support pipe 1 and the concrete 5 is further ensured. The distance between the outer edge of the lower sealing plate 3 and the outer tube wall of the support tube 1 is 100mm.
The length of the reinforcing steel bars 2 outside the support tube 1 is 120mm, and the length of the reinforcing steel bars 2 inside the support tube 1 is 20mm, so that the support tube 1 and the concrete 5 outside and inside the support tube can be reliably fixed.
The reinforcing steel bars 2 are uniformly arranged on the supporting tube 1, and the setting heights of the reinforcing steel bars 2 are not uniform, so that the supporting tube 1 and the concrete 5 outside and inside the supporting tube are further ensured to be reliably fixed.
The support tube 1 adopts an old steel tube to replace a traditional wooden screw box to be used as an anchor bolt hole die; the lower sealing plate 3 seals the bottom end of the support tube 1 to prevent concrete 5 from entering the tube from the bottom end of the support tube 1. When the anchor bolt structure is used, the structure is placed at a designated position, then concrete 5 pouring is carried out, after the pouring is finished, the support tube 1 does not need to be taken out, so that the problem of hole collapse does not occur, the construction effect is ensured, after the concrete 5 outside the support tube 1 is solidified, the anchor bolt 4 is inserted into the support tube 1, and then in-tube grouting is carried out, so that the fixation of the anchor bolt 4 is completed; because the bolt hole die is not required to be put forward, other works can be completed by workers within waiting time, and labor and construction period are saved. The steel bars 2 extend into the support tube 1 and out of the support tube 1 simultaneously, and the concrete 5 poured in later stage is anchored with the tube wall of the support tube 1, so that the support tube 1 and the concrete 5 fixing blocks can be firmly combined. The pipe diameter of the supporting pipe 1 is larger than the diameter of the foundation bolt 4, so that the thickness and the strength of the concrete 5 between the supporting pipe 1 and the foundation bolt 4 are ensured to be large enough.
