Description

Technical Field

[0001] The utility model relates to the technical field of house construction, and particularly designs a pipe fixing device for fixing building materials for wall-penetrating pipes during house construction, in particular a building material fixing device for house construction. Background Art

[0002] In modern housing construction projects, pipeline building materials are an indispensable component and occupy an important position in plumbing construction. Traditional pipeline building materials are mainly made of rigid polyvinyl chloride pipes, random copolymer polypropylene pipes and aluminum-plastic composite pipes.

[0003] As the main water and heating pipes in buildings, they are generally large in diameter and need to be installed through the wall after drilling. Therefore, when large-diameter pipes are installed through the wall, they are generally required to be pre-fixed to ensure the positioning of the pipes during connection.

[0004] For example, in the patent document with patent publication number CN219035804U, a new type of wall-penetrating fixed sleeve for water pipes is disclosed, whose main structure includes an outer sleeve, an inner sleeve and a plurality of fixing bolts; the inner sleeve is sleeved in the outer sleeve, and there is a distance between the outer wall of the inner sleeve and the inner wall of the outer sleeve; and a plurality of fixing bolts are respectively screwed on the two ends of the outer sleeve, and the bottom ends of the plurality of fixing bolts can support the outer wall of the inner sleeve.

[0005] It can be seen from the above-mentioned wall-penetrating fixing sleeve that the position of the outer sleeve can be fine-tuned during positioning, and there is no need to make grooves or holes due to inaccurate reservations. However, this structure is only suitable for the positioning of horizontal wall-penetrating water pipes when fixing water pipe building materials in house construction. When the pipe building materials pass through the floor between the upper and lower floors, this wall-penetrating fixing sleeve is not suitable, because the vertical pipe has a greater downward gravity and does not have wall support like the horizontal pipe when it is installed.

[0006] To this end, the utility model optimizes the design for the problem of fixing pipe building materials during the installation of main pipes running through upper and lower floors during existing house construction. Hereby, a pipe fixing device is proposed for fixing wall-penetrating pipe building materials during house construction, so as to better solve the problems existing in the prior art. Utility Model Content

[0007] The utility model is to solve one of the above technical problems, and the technical scheme adopted is: a building material fixing device for house construction, comprising a through hole arranged on a floor slab, a vertically arranged main pipe is installed in the through hole, the upper end of the main pipe extends into the upper house, and the lower end of the main pipe extends into the lower house, a T-shaped pipe sleeve inserted into the through hole is arranged on the floor slab of the upper house, the vertical section of the T-shaped pipe sleeve extends into the through hole, the bottom of the horizontal section of the T-shaped pipe sleeve abuts against the top of the floor slab of the upper house, pipe jacking mechanisms are respectively installed on both sides of the main pipe in the upper house, the tops of the two pipe jacking mechanisms are used to press the outer side walls of the main pipe on both sides and clamp and position it, and the bottoms of the two pipe jacking mechanisms are both movable through the tightening through holes arranged at the corresponding positions of the T-shaped pipe sleeve and extend into the lower house.

[0008] In any of the above schemes, it is preferred that the pipe supporting mechanism includes a pressure-bearing rod which is inserted into the corresponding tightening through hole, the lower end of the pressure-bearing rod is a vertical section, the upper end of the pressure-bearing rod is inclined outward to form an inclined portion, an adjusting screw is screwed into the threaded through hole of the inclined portion, the upper end of the adjusting screw is movably inserted into the lateral positioning tube corresponding to the corresponding arc-shaped rubber seat through the insertion portion at its end, and the inner side wall of the arc-shaped rubber seat abuts against the outer side wall of the main pipe.

[0009] In any of the above solutions, preferably, an adjusting hand wheel is detachably fixedly mounted on the lower end of the adjusting screw.

[0010] In any of the above schemes, it is preferred that the angle between the central axis of the adjusting screw and the central axis of the main pipeline is 25°-35°.

[0011] In any of the above solutions, preferably, there is an interference fit between the tensioning through hole and the vertical section of the pressure-bearing rod.

[0012] In any of the above solutions, preferably, the two arc-shaped rubber seats are symmetrically arranged with respect to the central vertical plane of the main pipeline.

[0013] Preferably, in any of the above solutions, anti-slip grooves are provided on the inner side wall of each of the arc-shaped rubber seats.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The overall structure of the building material fixing device designed in the utility model is relatively simple, and it can complete the temporary lifting and positioning of the vertically arranged main pipelines running through the upper and lower floors, ensure the temporary positioning before connecting and installing the upper and lower adjacent main pipelines, effectively ensure the stability of the positioning, and avoid the main pipeline from falling after insertion.

[0016] 2. When positioning the main pipeline, the device relies on the T-shaped pipe sleeve to complete the lateral protection of the main pipeline, effectively avoiding the wear of the concrete at the inner end of the through hole when the main pipeline is inserted up and down, and reducing the resistance when the main pipeline is adjusted up and down.

[0017] 3. The pipe supporting mechanism in this device, which relies on plug-in positioning, can support its lower end on the outer wall of the main pipe in the upper house. By controlling the tightening force of each pipe supporting mechanism, the tightening force when frictionally tightening the outer wall of the main pipe can be effectively guaranteed, the effect of friction tightening braking can be guaranteed, and the vertical positioning stability of the main pipe can be improved.

[0018] 4. When the two pipe jacking mechanisms perform static pressure friction braking on both sides of the main pipe, the vertical pressure and horizontal pressure components are controlled by the angle between the pre-designed inclined portion of the pressure-bearing rod and the main pipe, effectively ensuring the tightening effect during tightening.

DETAILED DESCRIPTION

[0024] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 3 as shown in .

[0025] A building material fixing device for housing construction comprises a through hole 2 arranged on a floor 1, a vertically arranged main pipe 3 is installed in the through hole 2, the upper end of the main pipe 3 extends into an upper house 4, and the lower end of the main pipe 3 extends into a lower house 5, a T-shaped pipe sleeve 7 inserted into the through hole 2 is arranged on the floor 6 of the upper house 4, the vertical section of the T-shaped pipe sleeve 7 extends into the through hole 2, and the bottom of the horizontal section of the T-shaped pipe sleeve 7 abuts against the top of the floor 6 of the upper house 4, and pipe jacking mechanisms are respectively installed on both sides of the main pipe 3 in the upper house 4, the tops of the two pipe jacking mechanisms are used to press against the outer side walls of the main pipe 3 on both sides and clamp and position it, and the bottoms of the two pipe jacking mechanisms are both movable through the tightening through holes 8 arranged at the corresponding positions of the T-shaped pipe sleeve 7 and extend into the lower house 5. The building material fixing device for house construction in the present design is mainly used for the preliminary and temporary fixation of the main pipes 3 installed on the upper and lower floors before connection and positioning. By operating the pipe supporting mechanisms on both sides, the friction and tight positioning of the outer wall of the main pipe 3 can be effectively achieved, thereby preventing the main pipe 3 from falling downward. At the same time, this positioning method can be adjusted and controlled as needed during the installation process, which is convenient for temporary regulation.

[0026] In any of the above schemes, it is preferred that the pipe supporting mechanism includes a pressure-bearing rod 9 that is inserted into the corresponding tightening through hole 8, the lower end of the pressure-bearing rod 9 is a vertical section 901, and the upper end of the pressure-bearing rod 9 is inclined outward to form an inclined portion 902, and an adjusting screw 10 is screwed into the threaded through hole of the inclined portion 902, and the upper end of the adjusting screw 10 is movably inserted into the lateral positioning tube 12 fixedly connected to the corresponding arc-shaped rubber seat 11 through the insertion portion 1001 at its end, and the inner side wall of the arc-shaped rubber seat 11 abuts against the outer side wall of the main pipeline 3.

[0027] In any of the above solutions, preferably, an adjusting hand wheel 13 is detachably fixedly mounted on the lower end of the adjusting screw 10 .

[0028] It should be noted that: the pipe supporting mechanism designed in the utility model can effectively ensure the rotation control of the adjusting screw 10 by rotating the adjusting hand wheel 13 when in use. When the adjusting screw 10 drives the upper insertion part 1001 thereof to push the arc rubber seat 11 upward and laterally against the outer wall of the main pipe 3, the arc rubber seat 11 can be controlled to press against the outer wall of the main pipe 3 by the length and force of the upward screwing. When the adjusting screw 10 needs to be screwed downward, the arc rubber seat 11 can be controlled to move downward and outward at the same time by holding the hand.

[0029] In any of the above solutions, it is preferred that the angle between the central axis of the adjusting screw 10 and the central axis of the main pipeline 3 is 25°-35°.

[0030] Setting a suitable angle can effectively control the upward pressing angle of the current adjusting screw 10 against the arc rubber seat 11, thereby effectively controlling the pressing effect of the current arc rubber seat 11 against the main pipe 3 and the positioning stability brought by static friction, thereby ensuring the supporting stability of the entire arc rubber seat 11 on the main pipe 3.

[0031] In any of the above solutions, preferably, there is an interference fit between the tensioning through hole 8 and the vertical section 901 of the pressure-bearing rod 9 .

[0032] It should be noted that the interference fit method can effectively ensure the stability of the vertical section 901 of the entire pressure rod 9 when it is inserted and positioned downward, thereby preventing the pressure rod 9 from shaking randomly.

[0033] In any of the above solutions, preferably, the two arc-shaped rubber seats 11 are symmetrically arranged with respect to the central vertical plane of the main pipeline 3 .

[0034] The symmetrically arranged arc-shaped rubber seat 11 can effectively rely on the current alignment clamping to effectively control the alignment clamping effect and the relative stability of the clamping when clamping and positioning the main pipe 3.

[0035] In any of the above solutions, preferably, anti-slip grooves are provided on the inner side walls of each of the arc-shaped rubber seats 11 .

[0036] When the inner wall of the arc-shaped rubber seat 11 is pressed against the outer wall of the main pipe 3 , the anti-slip pattern can effectively increase the friction effect, ensure the upward pressing and positioning effect, and ensure the stability of the entire main pipe 3 when it is in contact.

[0037] Specific working principle: This device is used for the preliminary and temporary fixation of the main pipeline 3 installed on the upper and lower floors before connection and positioning. Before using this device, it is necessary to first insert the T-shaped pipe sleeve 7 into the corresponding through hole 2, and then install the corresponding pipe jacking mechanism on both sides, insert the main pipeline 3, and when the main pipeline 3 is inserted in place, the adjustment handwheel 13 on the pipe jacking mechanism on both sides is adjusted to achieve the upward and inward pressing of the main pipeline 3 using the arc rubber seat 11, thereby completing the effective positioning of the main pipeline 3. In specific operation, by operating the pipe jacking mechanism on both sides, the friction and tight positioning of the outer wall of the main pipeline 3 can be effectively achieved, thereby preventing the main pipeline 3 from falling downward. At the same time, this positioning method can be adjusted and controlled as needed during the installation process, which is convenient for temporary regulation.

[0038] In summary, it can be seen that the overall structure of the building material fixing device of the present design is relatively simple, and it can complete the temporary lifting and positioning of the vertically arranged main pipe 3 running through the upper and lower floors, ensure the temporary positioning before the upper and lower adjacent main pipes 3 are connected and installed, effectively ensure the stability of the positioning, and avoid the main pipe 3 from falling after insertion; when the main pipe 3 is positioned by using the present device, the lateral protection of the main pipe 3 is completed by relying on the T-shaped pipe sleeve 7, and the wear of the concrete at the inner end of the through hole 2 when the main pipe 3 is inserted up and down is effectively avoided, and the resistance of the main pipe 3 when it is adjusted up and down is reduced; the pipe jacking relying on the insertion positioning The mechanism can support its lower end on the outer wall of the main pipe 3 in the upper house 4. By relying on the control of the clamping force of each pipe supporting mechanism, the clamping force when the outer wall of the main pipe 3 is frictionally clamped can be effectively guaranteed, the effect of friction clamping braking can be guaranteed, and the vertical positioning stability of the main pipe 3 is improved; when the two pipe supporting mechanisms perform static pressure friction braking on both sides of the main pipe 3, the angle between the inclined portion 902 of the pre-designed pressure-bearing rod 9 and the main pipe 3 is used to control the component of the vertical pressure and the horizontal pressure, effectively ensuring that the clamping effect can be effectively guaranteed when clamping.
