Summary of the Invention

Problems to be Solved by the Invention

[0004] Since existing garages (warehouses) are installed on simple foundations, they are often deformed due to earthquakes or ground freezing. In particular, the roof is easily affected. When incorporating a retrofitted reinforcement structure inside the garage (warehouse), it is necessary to adjust the attachment level on the lower surface of the roof. However, there are no members corresponding to the unevenness for roof attachment, and it was not easily constructible by an ordinary person.

[0005] The garage roof reinforcement structure with a jack of the present invention solves the above problems and provides a post-installation reinforcement structure for the roof of a garage (warehouse) that can be easily constructed by an ordinary person even for on-site construction and level adjustment.

Means for Solving the Problems

[0006] The garage roof reinforcement structure with a jack according to the present invention is constructed retrospectively along the inner wall surface and the back surface of the roof of the garage (warehouse) 10. One unit consists of two column members 1-1 on the left and right, one long beam member 1-2, and four truss members 1-3. The left and right ends are a U-shaped frame member 1 with a truss structure, a short beam member 2 that supports the load received by the roof via a beam member 4 in the depth direction of the garage (warehouse), and a jack 3 for level adjustment provided between the long beam member 1-2 and the short beam member 2. One end of the truss member 1-3 has a length exceeding the upper surface of the short beam member 2 that extends the truss structure of the U-shaped frame member 1, and the short beam member 2 is clamped from the front and back in the depth direction of the garage (warehouse) using the two truss members 1-3. The other end of the truss member 1-3 is fixed to the U-shaped frame member 1, and the shaft of the jack 3 is rotatably fitted into coaxial holes provided in the long beam member 1-2 and the short beam member 2 (jack shaft movement restriction function). The depth thickness of the long beam member 1-2 and the short beam member 2 of the U-shaped frame member 1 is the same. By arranging a plurality of units of the above structure, the garage roof reinforcement structure with a jack according to the present invention is constructed.

Effects of the Invention

[0007] The garage roof reinforcement structure with a jack according to the present invention clamps the short beam member 2 that supports the roof load with the truss member 1-3 and arranges the jack 3 between the short beam member 2 and the long beam member 1-2, making it easy to adjust the level in the vertical direction of the garage roof. In addition, by pre-processing each component in a factory, even a layperson can easily perform on-site construction.

Mode for Carrying Out the Invention

[0009] Example 1 of the case where the garage roof reinforcement structure with a jack of the present invention is installed in a garage with a flat inner wall surface structure will be described below with reference to FIGS. 1 to 5.

[0010] (Example 1) As shown in FIG. 1, Example 1 is an example in which the garage roof reinforcement structure with a jack (1 unit) of the present invention shown in FIG. 2 is arranged in parallel and evenly in the depth direction of the garage so as to bear the horizontal force and the vertical snow load during an earthquake.

[0011] The garage roof reinforcement structure with jacks (1 unit) of the present invention, as shown in Fig. 2, is composed of U-shaped frame members 1 with a truss structure at both left and right ends, short beam members 2 that support the roof load, and leveling jacks 3 installed between the upper surface of the U-shaped frame members 1 and the short beam members 2. The U-shaped frame members 1 consist of two column members 1-1 on the left and right, one long beam member 1-2, and four truss members 1-3. As shown in Figs. 3 and 4, using two truss members 1-3 that extend the truss structure in the roof surface direction, the left and right ends of the short beam members 2 arranged in the garage frontage direction (short side direction) are clamped from the front and back in the depth direction of the garage. By this clamping, the movement of the short beam members 2 in the depth direction of the garage is suppressed. The column members 1-1 and the long beam member 1-2 are connected and fixed using end connection plates 1-4, and the truss members 1-3 are fixed to the U-shaped frame members 1 using bolts and nuts 1-5.

[0012] Also, as shown in Fig. 5, holes for inserting the shafts of the jacks 3 are provided on the long beam member 1-2 and the short beam member 2 on the same axis, and the shafts of the jacks 3 are rotatably fitted into these holes. As a result, the jacks 3 do not move from the installation locations (shaft movement restriction function of the jacks) and only move in the vertical direction, enabling the leveling of the depth direction beam members 4 of the garage arranged above the short beam members 2 that directly contact the back surface of the roof.

[0013] In the above Example 1, jacks 3 with a shaft movement restriction function were used, but the garage roof reinforcement structure with jacks of the present invention can also use jacks without a shaft movement restriction function. In that case, as shown in Fig. 6, holes for inserting the movement restriction bolts 5 are provided on the long beam member 1-2 and the short beam member 2 on the same axis, and by rotatably fitting into these holes, the same leveling as the jacks 3 with a shaft movement restriction function can be performed.

[0014] Also, as shown in Fig. 7, by arranging load sensors -6 on the upper or lower part of the jacks 3, it becomes possible to easily grasp the snow removal timing of the roof by monitoring the snow load.

[0015] (Construction method) Next, an example of the construction method related to Example 1 is shown below. Each component member of the U-shaped frame material 1 of the present invention, namely, the column material 1-1, the long beam material 1-2, the truss material 1-3, the short beam material 2, and further the depth-direction beam material 4 of the garage, is pre-processed in the factory and assembled and fixed to the inner lower end of the garage (warehouse) 10 on-site. At this time, while adjusting the level of the short beam material 2 using the jack 3 provided between the long beam material 1-2 and the short beam material 2, it is necessary to arrange them so that there is no gap between the depth-direction beam material 4 of the garage and the inner surface side of the roof of the garage (warehouse) 10. In addition, the garage roof reinforcement structure with a jack of the present invention needs to have rigidity to resist the bending moment caused by the vertical force of the snow load and the horizontal force during an earthquake, and it is necessary to use a material with corresponding strength.

[0016] The following describes the construction procedure of the garage (warehouse) 10 when the inner wall surface has a flat plate structure. (1) The column material 1-1 is temporarily fixed with gum tape or the like at the inner lower end of the garage (warehouse) 10 to be reinforced so that the heights match. (2) The long beam material 1-2 is placed on the upper end of the column material 1-1, and the column material 1-1 and the long beam material 1-2 are temporarily fixed with bolts and nuts 1-5 by the end connection plate 1-4. (3) From below the hole of the short beam material 2 pre-processed in the factory, the upper shaft of the jack 3 with an axial movement limiting function is inserted and fixed. (4) The short beam material 2 incorporating the jack 3 is installed on the long beam material 1-2. The four truss materials 1-3 sandwich the short beam material 2, and the truss materials 1-3 are temporarily fixed with bolts and nuts 1-5 on both sides (front and back) of the column material 1-1 and the long beam material 1-2 so that both corners of the U-shaped frame material 1 form a truss structure. (5) Similarly, the above-mentioned component members are evenly arranged in the depth direction. Note that the number of installation locations is increased or decreased in consideration of the roof load. (6) The horizontal material (upper) 7, the horizontal material (lower) 8, and the truss material (diagonal) 9 are arranged on the side surface of the column material 1-1 and fixed with bolts and nuts 1-5. (7) The depth-direction beam material 4 is placed on the upper part of the short beam material 2. (8) Extend and retract the jack 3 to adjust the level so that the depth-direction beam member 4 of the garage lightly touches the lower surface of the roof. For fine adjustment, visually confirm and check based on the lateral movement status of the depth-direction beam member 4 of the garage. (9) Tighten the bolts and nuts 1-5 firmly. (10) Remove the temporary fixing gum tape etc. of the column member 1-1.

[0017] Also, when a load sensor-6 is used in combination with the jack 3, it becomes possible to monitor the snow load, making it easy to grasp the limit point of snow removal in the garage (warehouse) 10, and also an effect of reducing the number of snow removal times can be expected. Note that the above is the construction procedure for the garage (warehouse) 10 when the inner wall surface has a flat plate structure. In the case of a garage (warehouse) with a corrugated plate structure for the inner wall surface, the step (6) can be omitted.

[0018] (Example 2) Example 2 is a reinforcement method corresponding to the snow shelter that can be formed at the roof end of the entrance of the garage (warehouse) 10 depending on the wind direction during snowfall (occurring on the leeward side). As shown in Fig. 8, it is an example in which the jack-equipped garage roof reinforcement structure (1 unit) of the present invention is densely arranged near the entrance of the garage (warehouse) 10. Industrial applicability

[0019] The jack-equipped garage roof reinforcement structure of the present invention can also be applied to the roof parts of newly constructed garages and warehouses. Also, when a load sensor-6 is used in combination with the jack 3, it can also be applied to monitoring the snow load on the roofs of houses etc.
