Description

Technical Field

[0001] This invention relates to the field of steel truss floor decking construction technology, and in particular to a grout-proof structure and construction method for steel truss floor decking in a sloping roof environment. Background Technology

[0002] Because the specifications of steel truss floor decking are fixed, and various errors exist in actual production and construction, the layout design of steel truss floor decking cannot be completely consistent with the actual construction layout. During construction, the last steel truss floor decking is often larger than the design width. In this case, the last steel truss floor decking needs to be placed on top of the previous steel truss floor decking by a certain width. As a result, grout leakage will occur when pouring concrete, affecting the appearance quality of the floor slab.

[0003] A search of CN111576706A reveals a grout-proof connecting plate for reinforced truss floor slabs, comprising a main plate, a first hook portion connected to a first end of the main plate and used for a mating connection with a first reinforced truss floor slab, and a second hook portion connected to a second end of the main plate and used for a mating connection with a second reinforced truss floor slab. The angle between the first hook portion and the main plate is equal to the bending angle of the first reinforced truss floor slab's mating connection, and the angle between the second hook portion and the main plate is equal to the bending angle of the second reinforced truss floor slab's mating connection. By placing a grout-proof connecting plate at the overlapping position of the reinforced truss floor slabs and fixing it with screws, grout leakage can be controlled during concrete pouring. However, this structure requires the modification of the grout-proof connecting plate structure, and therefore, the risk of grout leakage still exists. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steel truss floor deck grout leak prevention structure and construction method for sloping roof environments, which achieves efficient leak prevention between floor decks without damaging the connection structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grout-proof structure for steel truss floor decking in a pitched roof environment includes a main body. Each end of the main body is provided with a connecting part that bends inward at the top. The connecting parts of two adjacent main bodies are sealed together by a grout-proof component. The bottom of the grout-proof component is provided with a closing structure that clamps two connecting parts in its natural state. The connecting parts are provided with a sealing groove that seals with the closing structure.

[0007] Based on the above solution, the following improvements are made: a sealing area is integrally formed on the connecting part, and an anti-detachment part adapted to the sealing area is integrally formed on the anti-leakage part. After the sealing area is connected to the sealing groove, it is adapted to the anti-detachment part for sealing.

[0008] Based on the above solution, the following improvements are made: the connecting part includes an integrally formed installation part, a deflection part, and a connecting part. The deflection part is located between the installation part and the connecting part. The sealing groove is arranged on the installation part, and the deflection part is inclinedly arranged between the installation part and the connecting part. The sealing area is arranged at the free end of the connecting part. The installation part is integrally formed with the main body. When the anti-leakage grouting component is installed, the closing structure moves linearly along the length of the installation part. When sealing and connecting, the closing structure is in the sealing groove and applies pressure to the deflection part outward to deform it and adapt and hook the anti-detachment part and the sealing area.

[0009] Based on the above solution, the following improvements are made: the main body has an integrally formed limiting area protruding to the top, and a limiting groove is provided at the top inside the limiting area. The height of the limiting groove is lower than the center height of the sealing groove. The outer side of the closing structure has an integrally formed support area that matches the limiting groove.

[0010] Based on the above scheme, the following improvements are made: when the closing structure slides linearly along the length of the connecting part, the free end of the support area abuts against the inner side of the limiting area and is in an elastic compression state. When the closing structure and the sealing groove are adapted, the free end of the support area is inserted into the limiting groove in a natural state, while the deflected part is further pressured and supported.

[0011] Based on the above scheme, the following improvement is made: the cross-section of the limiting area is an inverted L-shaped structure.

[0012] Based on the above solution, the following improvements are made: a sealing gasket is provided on the side of the sealing groove that is adapted to the closing structure and on the side of the limiting area that is opposite to the supporting area.

[0013] Based on the above scheme, the following improvements are made: pressure ribs are arranged sequentially along the outer extension direction of the closing structure.

[0014] Based on the above solution, the following improvements are made: the anti-detachment part is arranged on the inner side of the anti-leakage grout component and the anti-detachment part is located on the outer or inner side of the sealing area.

[0015] A construction method for a steel truss floor decking anti-grout leakage structure in a pitched roof environment, the construction steps are as follows:

[0016] Install the two main parts in the designed positions according to the drawings. The installation parts of the two connecting parts are encompassed by the closing structure of the anti-leakage component. Slide it in a straight line along the length of the first connecting part until the end of the first connecting part and the closing structure of the anti-leakage component are flush. As the anti-leakage component is pulled upward, the closing structure will gradually apply pressure to the deflected part along the installation part until the closing structure and the sealing groove are adapted and sealed. The deflected part will drive the connecting part and the sealing area on it to move outward. The sealing area will adapt and seal the anti-detachment part. At the same time as the closing structure and the sealing groove are adapted and sealed, and the sealing area and the anti-detachment part are adapted and sealed, the support area will enter the limiting groove and change from the elastic compression state to the natural state to prevent the anti-leakage component from falling. At the same time, the closing structure is obliquely supported to further ensure the sealing effect of the closing structure and the sealing groove, and the sealing area and the anti-detachment part.

[0017] Compared to existing technologies, this invention offers the following advantages: During installation, the closing structure moves linearly along the length of the installation portion of the connecting part. When the closing structure and the end face of the connecting part are flush, the upward movement of the anti-leakage component allows the closing structure and the sealing groove to fit together. During this fitting process, the closing structure applies pressure to the deflected portion, ensuring a tight seal between the anti-detachment component and the sealing area. Simultaneously, the supporting area enters the limiting groove and transitions from an elastically compressed state (when the closing structure moves linearly along the length of the installation portion of the connecting part) to a natural state, preventing the anti-leakage component from falling. Furthermore, the oblique side support of the closing structure further ensures a tight seal between the closing structure and the sealing groove, as well as a tight seal between the sealing area and the anti-detachment component. In summary, this invention achieves triple protection against grout leakage without damaging the connecting structure. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a grout-proof structure for steel truss floor decking in a pitched roof environment includes a main body 1. Each end of the main body 1 is provided with a connecting part 2 that bends inward at the top. The connecting parts 2 of two adjacent main bodies 1 are sealed together by a grout-proof component 3. The bottom of the grout-proof component 3 is provided with a closing structure 4, which clamps the two connecting parts 2 in its natural state. The connecting part 2 is provided with a sealing groove 5 that seals with the closing structure 4. A sealing gasket is provided on the side of the sealing groove 5 that is adapted to the closing structure 4 to ensure that the two are in a highly efficient sealing state after adaptation.

[0025] Among them, the connecting part 2 has an integrally formed sealing area 6, and the anti-leakage part 3 has an integrally formed anti-detachment part 7 that is adapted to the sealing area 6. After the sealing area 6 is connected to the closing structure 4 and the sealing groove 5, it forms a hook state with the anti-detachment part 7 and is adapted to seal. The anti-detachment part 7 is arranged on the inner side of the anti-leakage part 3 and is located on the inner side of the sealing area 6. The cross-section of the anti-detachment part 7 and the sealing area 6 are both L-shaped structures. The outer extension direction of the closing structure 4 is provided with pressure ribs 14 in sequence. The pressure ribs 14 can ensure the clamping force of the closing structure on the sealing groove 5.

[0026] The connecting part 12 includes an integrally formed mounting part 8, a deflecting part 9, and a connecting part 10. The deflecting part 9 is located between the mounting part 8 and the connecting part 10. The sealing groove 5 is arranged on the mounting part 8, and the deflecting part 9 is inclinedly arranged between the mounting part 8 and the connecting part 10. The sealing area 6 is arranged at the free end of the connecting part 10. The mounting part 8 is integrally formed with the main body part 1. When the anti-leakage grouting component 3 is installed, the closing structure 4 moves linearly along the length of the mounting part 8. When sealing and connecting, the closing structure 4 is in the sealing groove 5 and applies pressure to the deflecting part 9 outward to deform it and adapt and hook the anti-detachment part 7 and the sealing area 6. When the deflecting part 9 deflects outward, the connecting part 10 can contact the inner wall of the anti-leakage grouting component 3 and undergo a certain deformation before sealing and installing with the anti-detachment part 7. Alternatively, when the deflecting part 9 deflects outward, the connecting part 10 can not contact the inner wall of the anti-leakage grouting component 3 and does not deform, and can directly seal and install with the anti-detachment part 7.

[0027] During installation, the sealing structure 4 of the anti-leakage component 3 is inserted through the outside of the two connecting parts 2. The anti-leakage component 3 is slid linearly along the length of the installation part 8 of the connecting part 2 until the end face of the anti-leakage component 3 is flush with the end face of the connecting part 2. Then, the anti-leakage component 3 is moved upward. The sealing structure 4 will first apply pressure to the deflection part 9, causing the deflection part 9 and the connecting part 10 to deflect outward. The anti-detachment part 7 and the sealing area 6 will gradually seal and adapt. When the sealing structure 4 and the sealing groove 5 are sealed and adapted, the anti-detachment part 7 and the sealing area 6 are also sealed and adapted, achieving a double sealing effect to ensure the anti-leakage effect, while not causing any substantial damage to the adjacent two floor deck structures.

[0028] Example 2, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the following improvements are made based on the above embodiment: A limiting region 11 protruding upward is integrally formed on the main body 1, and the cross-section of the limiting region 11 is an inverted L-shaped structure. A limiting groove 12 is provided on the top inner side of the limiting region 11, and the height of the limiting groove 12 is lower than the center height of the sealing groove 5. A support region 13 adapted to the limiting groove 12 is integrally formed on the outer side of the closing structure 4, and a sealing gasket is provided on the side of the limiting region 11 opposite to the support region 13. When the closing structure 4 slides linearly along the length of the installation portion 8 of the connecting part 2, the free end of the support area 13 abuts against the inner side of the limiting area 11, and at this time the support area 13 is in an elastic compression state. When the closing structure 4 and the sealing groove 5 are adapted, the free end of the support area 13 will automatically be inserted into the limiting groove 12. At this time, the support area 13 is in a natural state, and at the same time, the deflection portion 9 and the closing structure 4 are further pressured and supported, so that the anti-detachment portion 7 and the sealing node of the sealing area 6, the sealing node of the sealing groove 5 and the closing structure 4, the support area 13 and the limiting area 12 form a structurally stable triangle, preventing the anti-leakage component 3 from loosening when the concrete is poured into the floor deck.

[0029] A construction method for a steel truss floor deck grout leak-proof structure in a pitched roof environment, the construction steps are as follows:

[0030] Install the two main parts 1 in the designed positions according to the drawings. The installation part 8 of the two connecting parts is encompassed by the closing structure 4 of the anti-leakage grouting component 3. It slides straight along the length of the connecting part 2 until the ends of the connecting part 2 and the closing structure 4 of the anti-leakage grouting component 3 are flush. As the anti-leakage grouting component 3 is pulled upward, the closing structure 4 will gradually apply pressure to the deflection part 9 along the installation part 8 until the closing structure 4 and the sealing groove 5 are adapted and sealed. The deflection part 9 will drive the connecting part 10 and the sealing area 6 on it to move outward. The sealing area 6 will adapt and seal the anti-detachment part 7. While the closing structure 4 and the sealing groove 5 are adapted and sealed, and the sealing area 6 and the anti-detachment part 7 are adapted and sealed, the support area 13 will enter the limiting groove 12 and change from the elastic compression state to the natural state to prevent the anti-leakage grouting component 3 from falling. At the same time, the closing structure 4 is obliquely supported to further ensure the adaptation and sealing effect of the closing structure 4 and the sealing groove 5, and the sealing area 6 and the anti-detachment part 7.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
